Abstract

PURPOSE:To eject a cassette tape to the outside without damaging the tape even when respective motors do not move by providing a transmission system which can obtain driving force instead of a mode motor, a reel motor and a cassette loading motor. CONSTITUTION:A gear 41b is provided to the shaft 41a of the mode motor 41 and a gear 51 meshing with the gear 41b is provided. By rotating the gear 51 by a disk 52, the gear 41b can be rotated and it can function instead of the motor 41. Then, a worm gear 61 meshing with a gear 60 which is press- fitting in the driving shaft 13 of the reel motor 12 is provided. The motor 12 can be rotated by rotating a disk 64 by the use of the gear 61. Therefore, the motor 12 can be rotated even when the motor 12 does not move. In the case of the cassette loading motor, the motor can be rotated in the same way.

Further, the tips of the reel stands 11m and 11b are shaped to engage with the reel ha and Sb of the cassette case 1. The cassette case 1 is inserted through the force set insertion port (not shown) by the cassette loading mechanism (shown in FIG. 3), and the reel knobs 3a and 3b engage with the reel bases 11&, 1lb. It is moved to a predetermined position.

When the cassette case 1 is in a predetermined position, the guide A20 and the guide B2i are inserted into the holes on the back side of the cassette case 1, and the guides A20, B21, and C22 are used to position the cassette case 1 in the front, back, left, and right directions. is positioned. When the cassette case 1 is in a predetermined position, the front lid is opened, and there is a boat 53 to which the entry guide roller 50 and the inclined posts 51 and 52 are integrally attached, and a drawer arm to which the guide post 54 is attached. 35. Mechanical elements such as the Vinci roller 57 that is pressed onto the drive shaft 36a of the cab stan motor 36 to send out the magnetic tape 2, the Vinci roller arm 39 to which the guide post 38 is attached, and the exit drawer arm 40 are used to feed the magnetic tape. These mechanical elements are located on the opposite side of the rotary cylinder 100 across the mode motor 4.
1, the magnetic tag 2 moves in the directions of arrows A, B, C, and D in the figure, and wraps the magnetic tag 2 around the rotating cylinder. In particular, the boat 33 is positioned by a carriage 42 fixed to the mechanical chassis 1S, so that the magnetic tag 2 is accurately wound around the rotating cylinder 1o. Next, referring to FIGS. 1 and 2, the operation from the mode motor 41 to the operation of the mechanical elements will be explained in detail. The mode motor 41 is attached to the mounting portion 13 of the mechanical chassis 15.

There are 7a and 47b mechanical gears 48. When a voltage is applied to the mode motor 41, the mode motor 41 rotates, the locking gears 45, 44, 45 and the mode gear 46 rotate, and on the other hand, the ring gear 4B moves via the gear 47. The boat 35 and the ring gear 48 are flexibly connected by a connecting member (not shown), and when the ring gear 48 rotates clockwise when viewed from above, the boat 55 moves in the direction indicated by the arrow in the figure. catcher 42

One part forms a gear, and rotates in the direction of arrow B in the figure as the ring gear 480 rotates in mesh with the ring gear 48. On the other hand, in conjunction with the slider 49 having a boss that engages with the mode gear 460 cam tile, the pinch row 2 arm 59 and the output side pull-out arm 4o operate, and as the ring gear 4B rotates, the pinch roller arm 59 and the output side pull-out arm 4o operate. The side drawer arms 4G move in the directions of arrows C and D in the figure, respectively. As described above, in response to the operation of the mode motor 41, the boat 55, the pull-out arm 35, and the exit-side pull-out arm 4o of the Vinci roller arm 59 pull out the magnetic tape 2 in the cassette case 1 and wrap it around the rotating cylinder 1o. On the other hand, a shaft 5o parallel to the mode motor 41 is held in the mechanical chassis 13, and a gear 51 is press-fitted into one end, and a disk 52 is press-fitted into the other end.
It slides in the G direction and is always biased in the G direction by a spring 53 at the other end. And the arrow from the outside? When force is added in the direction, the entire axis 50 becomes an arrow? The gear 51 press-fitted into the end meshes with the gear 4lb press-fitted into the mode motor 41. Therefore, for example, if a hole is made in the front panel of the device so that the disc 52 is visible, a groove is provided on the surface of the disc 520, and a screwdriver is inserted from the outside into the groove on the surface of the disc 52. The ring gear 48 can be rotated by applying force in the direction of the arrow r, meshing the gear 51 and the gear 4lb, and rotating the driver. Therefore, if the driver is rotated so that the ring gear 48 rotates counterclockwise even if the mode motor 41 does not move, the boat 53, which is a mechanical element,
The drawer arm 35, bi/tirola arm 39, and exit side drawer arm 40 return to their positions in the cassette case 1. On the other hand, the 1% air tape 2 is attached to the drive shaft 1 of the reel motor 12.
