AUTOMATIC VENDING MACHINE

The sales of tombola lottery tickets from stands in streets and market places, shopping centres and in other places, where a lot of people are circulating
have recently become more and more unprofitable for the organizers of the lotteries, mostly charity organizations, clubs and associations, since a non-negligible part of the income from the sales of the lottery tickets is
consumed by salaries to the staff that handles the
sales. Furthermore, it may be difficult to recruit such staff at a reasonable cost, especially in case of
providing personnel for a tombola stand which is placed outdoors in winter.
Attempts have already been made to solve the
problem by making the sales of the lottery tickets
completely automatic such that the purchaser of the
lottery tickets serves himself by a coin operated vending machine. The most frequent automatic lottery vending
machine does not, however, operate with common rolled tombola tickets but with tickets of the slip type, which by the pull of a handle are dispensed one at a time from a roll of such lottery tickets in a continuous path. The printing of the lottery tickets of the roll is made in such a way that the alotment of the numbers is accidental, and thus it is not possible to foresee which number will follow on a lottery ticket just dispensed.
However, it is a desire of purchasers of lottery tickets as well as organizers that an automatic lottery vending machine dispenses lottery tickets of the
appearance which is commonly used for the usual manually operated tombola, i.e. lottery tickets in the form of a rolled piece of paper which is sealed at its ends, but so far no such automatic lottery vending machine has
been designed, which has had any practical application

/ of significance.
The purpose of the invention is to satisfy said desire, and more generally the invention relates to an automatic vending machine having the characterizing features appearing from claim 1.
Although the automatic vending machine according t the invention has been created to be used as an automat lottery vending machine and to satisfy the existing nee for such a machine which is operating with conventional tombola lottery tickets the automatic vending machine according to the invention may be arranged for automati sales of other objects than lottery tickets, for instan goods in packages of different kinds provided that uniform packages are used in each individual case.
In order to elucidate the invention an embodiment thereof will be described in more detail in the
following with reference to the accompanying drawings in which
FIG. 1 is a perspective view, partly a sectional view of an automatic lottery vending machine
according to the invention,
FIG. 2 is an enlarged fragmentary perspective view of the ticket container proper with a dispensing device ,
FIG. 3 is a side view, partly a vertical cross
sectional view, of the ticket container with the dispensing device,
FIG. 4 is a plane view of the ticket container wit the dispensing device and
FIG. 5 is an electrical circuit diagram for the automatic lottery vending machine.
The automatic lottery vending machine shown comprises a frame 10 having a substantially cylindrical portion 11 which is provided with a base 12 at the lowe end and provided with a top lid 13 at the upper end. A supporting device 14 placed inside the cylindrical portion 11 supports a container 15 which comprises a cylindrical wall 16 and a bottom 17 the container being bevelled at its free edge 18. The container 15 is
supported with its bottom 17 in a sloping position. In the present case the slopinq angle is approximately 60° but it may deviate more or less from this angle in one direction or the other. A cylindrical hopper 19 is detachably mounted inside the cylindrical portion 11 in a vertical position by means of a suitable fastening device, e.g. a pivoted flap 20, as shown, the open lower end 21 of the hopper, which is bevelled, projecting downwards into the container 15.
On the upper surface of the bottom 17 of the
container a cylindrical disc 22 is rotatably mounted, which covers the bottom. The disc is mounted on the shaft of an electrical drive motor 24 by means of a screw connection 23, said motor being mounted to the lower side of the sloping bottom 17. The disc 22
suitably is made of a transparent material, e.g. plexiglass, and has on its upper surface a number of rib-shaped dogs 25 arranged obliquely. Along the periphery the disc is formed with a number of recesses 26 which are distributed regularly over the circumference of the disc. These recesses have almost the shape of triangular notches in the edge of the disc, defined by a bottom wall 27 and an end wall 28 at the end which is the rear end as seen in the intended rotational direction of the disc, indicated by an arrow in the drawings.
The hopper 19 is adapted to receive a large number of tickets of the conventional tombola type, consisting of a rolled piece of paper, which is sealed at its ends, and when a hopper containing such tombola tickets is positioned inside the cylindrical portion 11, the tickets will partly fall down into the container 15. The slope of the bottom 17 and the disc 22 must be sufficiently great to make possible the accumulation of tickets in the lower region of the container 15. In the figures a number of tombola tickets 29 are shown in the lower region of the container. The recesses 26 are dimensione to receive easily one ticket each but not more,- and when the disc 22 is rotated by means of the motor 24 tickets will thus be transported by the disc 22, lying in the recesses 26, the tickets being lifted from the lower region of the inclined container 15 to the upper region thereof. Simultaneously the tickets in the container 15 are stirred by means of the rib-shaped dogs 25 arranged on the disc 22.
In the upper region of the container 15 there is arranged in the corner between the side wall 16 and the bottom 17 an opening 30, partly in the side wall and partly in the bottom, adjacent the edge of the disc 22, through which a ticket lying in the recess 26 which is jus then passing the opening, can fall from the container 1 To the opening 30 a chute 31 is connected which at its lower end opens into a pocket 32 of the cylindrical portion 11 said pocket being accessible from the outsid to receive a ticket which falls from the container 15 through the opening 30. In the pocket 32 the ticket whi has fallen out can easily be picked up manually.
As tickets are discharged to the pocket 32 one after the other from the container 15 via the opening 30 and the chute 31 by the rotation of the disc 22 the tickets in the hopper 19 will fall down into the container 15.
The discharge of the tickets in the manner describ is controlled automatically and electrically in
dependence of the insertion of a coin into a coin slot 33 externally of the cylindrical portion 11 by means of the circuit shown in FIG. 5. The coin slot 33 may be of

a conventional type and includes an electrical switch 34 which is normally opened but is instantaneously closed by an inserted coin when it passes down into a coin collecting container 35.
The electrical control circuit is connected to a power source of e.g. 12 V the poles of which are
indicated at 36 in FIG. 5. Over the current source a relay coil 37 is connected via a thyristor 38 and a transistor 39 coupled in parallel therewith, and this relay coil forms part of a relay for controlling the power supply to the motor 24 which can operate by mains voltage. When the relay coil is energized, the motor is energized for rotating the disc 22. The switch 34 is connected via a resistor 40 between one pole of the power source 36 and the control electrode 38 of the thyristor and is connected to the other pole of the current source via a capacitor 41. The resistor 40 has a great resistance and therefore the current through this resistor is not sufficient to trigger the thyristor.
However, the capacitor 41 is charged via the resistor

40 and the capacitor has such a capacity that the stored electricity is sufficient to trigger the thyristor once. If the switch 34 is locked in locked position e.g. by a coin getting stuck or by damage, the current supplied to the thyristor 38 via the resistance 40 will not be sufficient to trigger the thyristor continuously. When the thyristor has been triggered by a discharge of the capacitor 41 this is again charged via the resistor 40 in order to make possible that the thyristor is triggered again by another discharge when a coin the next time closes the switch 34. When the thyristor has been triggered it will be
conducting until the current through the thyristor is interrupted or the thyristor is short-circuited.
A photo-transistor 42 is connected at its collector via a resistor 43 to one of the poles of the power source 36, while the emitter thereof is connected to the base of the transistor 39, and this photo-transistor 42 forms a light circuit together with a light emitting diode 44 associated with the photo-transistor, which is connected over the power source 36 via a resistor 45. It can be seen that the transistor 39 is connected in parallel with the thyristor 38. The transistor 39 is conducting only when the photo-transistor 42 is conducting, which it is when it is illuminated by the diode 44 (the light circuit is closed). Due to the fact that the transistor 39 is conducting the thyristor 38 is thus short-circuited and if it is then triggered and is conducting it will again become non-conducting by the short-circuiting. As long as it is conducting the transistor 39 - instead of the thvristor 38 - holds the circuit through the relay coil 37 closed but when it becomes non-conducting due to interruption of the light circuit, the current through the relay coil 37 will be interrupted and the thyristor 38 must be triggered again in order to energize the relay coil .
The photo-transistor 42 and the light emitting diode 44 are mounted on the container 15 at both sides of the disc 22 at a distance from the opening 30 which corresponds to the spacing of the recesses 26 in the disc 22, in order to sense if there is a ticket in the recess 26 which is next in turn to pass to the opening 30 at the rotation of the disc 22. When the light from the diode 44 is shielded from the photo-transistor 42 by a ticket 29A located in the said recess, the photo-transistor 42 is non-conducting, while it is conducting when there is no lottery ticket in this recess.
The function of the described lottery machine will now be as follows: If it is supposed that a coin is inserted into the coin slot 33 the switch 34 will be closed for a short while so that the thyristor 38 is triggered and becomes conducting and continues to be conducting after opening of the switch 34 when a coin has passed the switch. If it is further supposed that a ticket 29A is located in the recess 26 which is in turn to pass to the opening 30 at the rotation of the disc 22 the photo-transistor 42 and thus the transistor 39 are non-conducting when the relay coil 37 is
energized as a consequence of the thyristor 38 becoming conductive. When the relay coil 37 is energized the motor 24 starts and rotates the disc 22 in the direction of the arrow. Thereby, the ticket 29A is transported to the opening 30 and falls out through it whereafter it slides along the chute 31 into the pocket 32, where the lottery ticket purchaser picks up the ticket. When the ticket has passed from the position thereof between the diode 44 and the photo-transistor 42 so that the light circuit is again closed through the transparent disc 22 the transistor 39 will be conducting in parallel with the thyristor 38 whereby the thyristor will be non-conducting due to short-circuiting of the transistor 39 and the energization of the coil 37 henceforth will take place through the transistor. When the light circuit is again interrupted because a new ticket is transported by the disc 22 into the space between the diode 44 and the photo-transistor 42 and intercepts the light circuit, the photo-transistor 42 and thus the transistor 39 ceases to conduct so that the current through the relay coil 37 is interrupted. As a consequence thereof the motor 24 and the disc 22 are stopped.
Normally the recess 26 which is located behind the recess with the ticket 29A as seen in the rotational direction of the disc 22, will contain a new ticket which means that the photo-transistor 42 is shielded from light from the diode 44 already when the disc 22 has rotated only to the extent that corresponds to the spacing of the recesses 26, because the relay coil is no longer energized when the photo-transistor 42 is shielded from light. Thus, the disc 22 will stop and have a new ticket in position to be dispensed next time a coin is inserted into the coin slot 33. If on the other hand no ticket should be located in the following recess 26 next to that which has just delivered a ticket the disc 22 will be rotated until a recess 26 having a ticket located therein is inserted between the diode 44 and the photo-transistor 42. Then, the rotation of the disc 22 is again stopped. In other words the lottery machine is automatically made ready for dispensing a new ticket each time a ticket has been delivered to the pocket 32. However, in practice all recesses 26 will contain tickets so that the normal movement of the disc 22 consists of an intermittent movement corresponding to the spacing of the recesses, at least as long as there is a large number of tickets in the container 15. Only when a few tickets are left in the container 15 it may occur that an empty recess 26 will arrive at the diode 44 and the photo-transistor 42, but the arrangemen of the container 15 and the disc 22 guarantees that even the last ticket in the container will be picked up by the disc 22. In order to avoid an instantaneous inter-ception of the light circuit by the disc 22 when the portions separating adjacent recesses 26 pass between the diode 44 and the photo-transistor 42, the disc 22 is made from a transparent material. However, it may also consist of non-transparent material if the relay for the motor 24 or the electric circuit according to FIG. 5 has a sufficient inherent inertia in order not to react to the instantaneous shielding of the photo-transistor 42 which occurs when the said portions intercept the light circuit.
Suitably, signal lamps are provided to indicate the rotation of the disc 22 and to block simultaneously the coin slot 33 so that no coin can be inserted into the lottery machine during this time. Furthermore, the machine should suitably have means for indicating that the machine is short of lottery tickets and for blocking the coin slot 33 also in this case. For the last-mentioned purpose there may be arranged an oscillator which generates clock pulses and a counter which starts counting the clock pulses each time the motor 24 starts. When a certain number of clock pulses has been counted the motor circuit is interrupted via a thyristor which remains conductive until resetting takes place by interruption of the current through the thyristor or by short-circuiting of the thyristor. When the thyristor is conductive it can operate a relay which interrupts the circuit to the motor 24, blocks the coin slot and energizes an indicating lamp which indicates that the lottery tickets have run out of stock. Resetting takes place when new tickets are supplied. The time for deenergizing the motor is set by chanqing the frequency of the clock pulses.
An automatic lottery ticket vending machine
according to the invention is operating completely automatically; the only thing one has to do in order to obtain a ticket is to insert a coin in the coin slot and then to pick up the dispensed ticket at the place where lottery tickets are delivered. Furthermore, the machine can easily be arranged to operate with a supply of a large number of tickets, e.g. 5,000. The selection of the ticket to be delivered at each instance is guaranteed to be completely accidental, and it is completely impossible to ascertain the number of the next ticket.
