Title
(EN) DEVICE FOR ATTACHING DISK-LIKE RECORDING MEDIUM
(FR) DISPOSITIF D"ATTACHE D"UN SUPPORT D"ENREGISTREMENT EN FORME DE DISQUE
Abstract
(EN)
This device for attaching a disk-like recording medium prevents the central hole (11b) of a disk (11) from being damaged upon depression of the recording medium such as a floppy disk or the like onto a drive shaft (12) by the alignment of the central axis of the recording medium with that of the drive shaft (12) before pressing the recording medium onto the drive shaft (12). After the disk (11) is set at the drive shaft (12), a flange (13) is pressed toward the direction of an arrow (14). When the flange (13) is thus pressed, a protrudent member (18) is lowered through a pressing member (17). The protrudent member (18) is then outwardly expanded by the tapered portion (17a) of the pressing member (17) to thereby make contact with the central hole (11b) of the disk (11). When the protrudent member (18) makes thus contact with the central hole (11b), the disk (11) is moved to cause the central axis (11a) thereof to align with the central axis (12a) of the drive shaft (12). When the flange (13) is further pressed, the pressing member (17) is further lowered to thereby press the disk (11) onto the drive shaft (12).
(FR)
Ce dispositif d"attache d"un support d"enregistrement en forme de disque empeche que le trou central (11b) d"un disque (11) ne soit endommage lors de l"abaissement du support d"enregistrement tel qu"un disque souple sur un arbre d"entrainement (12) par alignement de l"axe central du support d"enregistrement avec celui de l"arbre d"entrainement (12) avant de presser le support d"enregistrement sur l"arbre d"entrainement (12). Une fois le disque (11) pose sur l"arbre d"entrainement (12), une bride (13) est pressee en direction d"une fleche (14). Lorsque la bride (13) est ainsi pressee, une saillie (18) est abaissee par l"intermediaire d"un element pressant (17). La saillie (18) s"etend vers l"exterieur par la partie conique (17a) de l"element pressant (17) pour etre en contact avec le trou central (11b) du disque (11). Lorsque la saillie (18) est ainsi en contact avec le trou central (11b), le disque (11) est deplace pour que son axe central (11a) soit aligne avec l"axe central (12a) de l"arbre d"entrainement (12). Lorsque la bride (13) est pressee davantage, l"element pressant (17) est encore abaisse pour ainsi presser le disque (11) sur l"arbre d"entrainement (12).
