CLAIMS:

1. A braille terminal (2) which extends in a transverse direction (6) and which has a plurality of cells (26), wherein each cell (26) has a plurality of pins (28) that can be felt by a user and are arranged in a plurality of columns (32) and a plurality of rows (30), and wherein the cell (26) is designed to represent an individual character, wherein a respective pin (28) can be actuated in each case individually by means of a piezoelectric bending transducer (54), and the piezoelectric bending transducers (54) are secured on a plurality of printed circuit boards (52), characterized by a plurality of modules (4) which are juxtaposed in the transverse direction (6) and which each have a module housing (12), wherein a plurality of cells (26) are integrated in the module (4).

2. A braille terminal (2) according to the preceding claim, wherein the columns (32) extend in a longitudinal direction (8) perpendicular to the transverse direction (6), wherein the printed circuit boards (52) are arranged above each other in the module housing (12) and, on each printed circuit board (52), a plurality of individual bending transducers (54) arranged next to each other in the transverse direction (6) are contacted and secured, wherein the bending transducers (54) of a respective printed circuit board (52) serve to drive the pins (28) of a respective row of all cells of the module (4).

3. A braille terminal (2) according to claim 1 or 2, wherein the module housing (12) has a closed design, with an upper wall (18) in which passages (60) for the pins (28) are introduced.

4. A braille terminal (2) according to claim 1, 2 or 3, wherein, in the region of the passages (60), an operating module (24) is mounted on the upper wall (18), which operating module (24) has the pins (28) extending through it and has an actuating button (34) for each cell (26) of the module (4).

5. A braille terminal (2) according to claim 4, wherein a holding plate (70) is placed inside the operating module (24), through which holding plate (70) the pins (28) are guided individually, and in which the pins (28) are held captive in order to permit removal along with the holding plate (70).

6. A braille terminal (2) according to claim 4 or 5, wherein a receiving space (36), in which a master board (38) lies, is formed between the actuating buttons (34) and the upper wall (18).

7. A braille terminal (2) according to claim 6, wherein the master boards (38) of adjacent modules (4) are connected to each other via plug connectors (44) which are mounted laterally on the master boards (38) in order to permit serial interconnection of the individual modules (4).

8. A braille terminal (2) according to any preceding claim, wherein the upper wall (18) has a further passage (62) for electrical contacting of the printed circuit boards (52).

9. A braille terminal (2) according to any preceding claim, wherein, on an upper face of the respective printed circuit board (52), spring contacts (58) are formed in order to permit electrical contacting with an underside of a printed circuit board (52) arranged above.

10. A braille terminal (2) according to any preceding claim, arranged such that signals and a supply voltage are routed serially and in a loop via the individual printed circuit boards (52).

11. A braille terminal (2) according to any preceding claim, wherein, on each printed circuit board (52), a driver chip (56) is arranged for driving the pins (28) that are assigned to the printed circuit board (52).

12. A braille terminal (2) according to any preceding claim, wherein the module housing (12) has a front part (22) and also a receiving cassette (20) which is closed at the front by the front part (22), wherein the printed circuit boards (52) are secured on the front part (22), and the printed circuit boards (52) with the bending transducers (54) secured thereon extend into the receiving cassette (20).

13. A braille terminal (2) according to claim 12, wherein the front part (22) for each printed circuit board (52) has an insert well (64) into which the respective printed circuit board (52) can be inserted, in the process of which the mutual contacting of the printed circuit boards (52) takes place automatically via the spring contacts (58).

A braille terminal (2) according to any preceding claim, wherein the module housing (12) has transverse passages (48) which lie opposite each other in the longitudinal direction (8) and which extend in the transverse direction (6) and have a connecting rod (46) guided through them.

15. A module for a braille terminal (2) according to preceding claim, which module has a module housing (12), wherein a plurality of cells (26) are integrated in the module housing (12), wherein each cell (26) has a plurality of pins (28) that can be felt by a user and are arranged in a plurality of columns (32) and a plurality of rows, and wherein the cell (26) is designed to represent an individual character, wherein a respective pin (28) can be actuated in each case individually by means of a piezoelectric bending transducer (54), and the piezoelectric bending transducers (54) are secured on a plurality of printed circuit boards (52).
