Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a disk loading device for loading and unloading a disk into and from a device body.

Conventional Structure and Problems Conventionally, a disk mounting device has been used that horizontally moves the disk to attach and detach the disk to and from the main body of the device. FIG. 1 is a perspective view schematically showing an apparatus using such a disk mounting device. In such a conventional device, a first drive motor and drive means are provided to move the disk 1 horizontally, and a second drive motor and second drive means are provided to move the disk 1 up and down. By rotating the drive motor to operate the first drive means, storing the pedestal 3 that supports the disk 1 inside the main body 38, and rotating the second drive motor to operate the second drive means. I was trying to attach Disc 1 to the turntable. However, since such a disk mounting device uses two drive motors and drive means, it requires many parts.
The drawback was that assembly was time consuming and costly. Another problem was that it was difficult to make the device smaller and lighter.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and provides a disk mounting device that has a simple configuration and can smoothly and reliably mount and remove a disk from a device body. With the goal.

Structure of the Invention The present invention includes a movable member that is provided to be slidable horizontally, a holding member that is provided to be able to slide up and down with respect to the movable member for holding a disk, and the movable member. a drive member that is held by the movable member and is slidably provided in the same direction as the movable member and linearly driven by a drive means; and an attachment provided on the movable member so as to bias the drive member against the movable member. a disk mounting device equipped with a means for
The movable member is simultaneously operated according to the movement of the driving member by the urging force of the urging means, and when the movable member stops at a predetermined position, only the driving member resists the urging force of the urging means. The holding member is operated in conjunction with this operation, and the urging means is operated to reverse the urging force generated by the urging means, thereby causing the driving member to operate. The disk can be attached to the main body of the device by reversing the biasing force in the direction.

Reference numeral 7 denotes a shaft that rotatably supports the driven pulley 10, transmission gear 11, and drive gear 12.

The operation of the disk loading device of this embodiment configured as described above will be explained below. now,
As shown in FIG. 8, when the disk 1 is placed on the holding member 2 and an opening/closing button (not shown) is pressed, the drive motor 9 is driven and the drive member 18 moves into the long groove formed in the base 8 integrally with the movable member 7. 8a, it is linearly driven in the direction of arrow A. When the driving member 18 and the movable member 7 move together in the direction of arrow A, and the movable member 7 moves to the position shown in FIG. Contact with 8c,
Although the movable member 7 stops moving, the drive motor 9 continues to rotate and the drive member 18 further moves in the direction of arrow A along the movable member 7. Cam part 1
8f engages with the lock arm 21 provided on the base 8, rotates it in the direction of arrow B, and engages the engaging portion 21a provided at the tip of the lock arm 21 with the lock shaft 31 provided on the movable member 7. Furthermore, since the drive shaft 18g provided on the drive member 18 engages with the sliding arm 5b provided on the rotary cam 5 to rotate it, the cam groove 5a provided on the rotary cam 5 The holding member 2 provided with the sliding shaft 2b that engages with is rotated in the direction of arrow C along the sliding surface provided between the holding member 2 and the pedestal 3, and move it downwards along. Since the holding member 2 is moved further below the surface of the turntable 25, the disk 1 is placed on the surface of the turntable 25 during the downward movement of the holding member 2. On the other hand, the cam shaft 24 provided on the clamp plate 23 engages with the cam groove 18c provided at the tip of the drive means and moves along the slope in the cam groove 18c, moving the clamp plate 23 in the direction of arrow D. Therefore, the clamper 26 provided at the tip of the clamp plate 23 moves together with the clamp plate in the direction of arrow D, and is placed on the upper surface of the disk 1 placed on the turntable 25, and the clamper 26 is rotated as shown in FIG. 25 to press the disk 1.

On the other hand, since the biasing gear 19 meshing with the small rack portion 18d provided on the drive member 18 rotates in conjunction with the movement of the drive member 18, the hook of the spring 20 provided on the biasing gear 19 rotates in conjunction with the movement of the drive member 18. The portion 19a passes through the center of rotation of the biasing gear 19, and the direction of the rotational moment applied to the biasing gear 19 by the spring 20 is reversed. That is, the biasing force applied to the drive member 18 is as shown by the arrow in FIG. 12B.
X Flips in _two directions. When the drive means 18 has moved to the position shown in FIG. 9, the switch A29 is operated by the cam piece 18e provided on the drive means 18 to stop the drive motor 9, thereby completing the operation. Although the drive motor 9 stops, the drive member 18 is activated by the biasing means 19 and 20.
Since it is biased in the _two directions of the arrow X, the stopped state is reliably maintained.

The shape of the drive member 18 at the portion that slides on the lock arm 21 after the lock arm 21 is rotated in the direction of arrow B is formed approximately equal to the movement locus of the drive member 18. Cam portion 18 provided on drive member 18
After being rotated in the direction of arrow B by f, it contacts the drive member 18 but does not rotate.

On the other hand, when taking out the disk 1, the drive motor 9 is reversed by operating an opening/closing button (not shown), and the drive member 18 is moved in the direction opposite to the direction of arrow A. The clamp plate 23 is rotated in the direction opposite to the direction of the arrow D, and the clamper 26 is moved away from the disk 1. The rotary cam 5 responds to the operation of the drive shaft 18g provided in the drive member 18 in parallel therewith.
is rotated by the spring 6 in the direction opposite to the direction of arrow B, and in conjunction with this, the holding member 2 is rotated in the direction of arrow C.
The disc 1 is lifted from the turntable 25 by moving upward while rotating in the opposite direction. Thereafter, the cam portion 1 provided on the drive member 18
8f is separated from the lock arm 21, and the lock arm 21 is rotated by the wire spring 22 in the direction opposite to the direction of the arrow B, releasing the engagement with the lock shaft 31 provided on the movable member 7. Therefore, the movable member 7 becomes movable and the drive member 18
After moving to the through-hole end 7b of the movable member 7, it moves together with the movable member 7 in the direction opposite to the arrow A. When the movable member 7 moves to the position shown in FIG. Complete the extraction operation of step 1.

Effects of the Invention As described above, according to the present invention, when the driving member is urged against the movable member to move horizontally together, and when the movable member stops at a predetermined position, only the driving member moves along the movable member. moves, and in conjunction with this movement, a holding base provided on the movable member so as to be slidable up and down is moved up and down, and in conjunction with this movement, the urging force of the urging means is reversed. Therefore, the movable member can be moved in the horizontal direction and the holding member can be moved in the vertical direction using one driving means. In addition, since horizontal movement and vertical movement are performed while one of the movements is stopped, reliable operation is possible. Furthermore, by making two movements possible with one linear movement, it is possible to smoothly mount and remove a disk with a simple structure.
