[Problem that the invention seeks to solve]

The cartridge insertion/removal mechanism in conventional disk storage devices is configured so that both sides of the cartridge are held and slid by clampers, so a large amount of power is required to expand the clampers, which reduces the capacity of the motor. In addition, when gripping and releasing the cartridge, it is necessary to move the stopper back and forth as the clamper opens and closes in order to correct the positional deviation of the cartridge, and the structure of the gripping part 111 is complicated. As a result, the volume and weight of the movable body increase, resulting in problems such as difficulty in moving the movable body at one high speed.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a disk storage device with a gripping mechanism that has a simple structure and can reliably insert and remove a cartridge.

[Means for solving problems]

In the disk storage device according to the present invention, when inserting a cartridge into a stocker or a playback device, a pusher of a movable body provided in the insertion/removal mechanism is brought into contact with the front of the cartridge and pushed in, and the cartridge is inserted into the stocker or playback device. When the cartridge is pulled out from the cartridge, the locking portion of the clamper provided on the movable body is engaged with the drawer side surface of the recessed locking portion of the cartridge, and the cartridge is pulled in.

[Effect]

In the insertion/removal mechanism according to the present invention, when inserting a cartridge into a stocker or a playback device, the cartridge is pushed by the abutting part of the movable body, and there is a gap between the locking part of the clamper and the locking part of the cartridge. Therefore, when releasing the grip on the cartridge, the clamper can be expanded with a light force.

In FIG. 7, the gripping mechanism provided on the movable body will be explained. The figure shows the cartridge (1) being gripped with the clamper ■ closed, and the left and right are the swing levers (
66). This is done by making the S dimension shown in the figure as small as possible, and by making the holding body 2
5 to make it as small as possible. In the figure, a pair of clampers ■ are composed of thin plates, and are rotatably attached to a pin (85) by being sandwiched between the two plates, and on the opposite side of the stop shown in the figure is a link () with a pin (84).

) is connected to the swing lever (aS) by a pin (83), and the figure shows the swing lever (66) rotated in the direction of arrow G by the spring force of the swing motor and in contact with the stopper (86). At this time, the center of rotation of the swing lever (66), the center of the bottle (83), and the center of the bottle (84) are arranged in a straight line. This is a toggle link structure that opens and closes the left and right clampers (A) symmetrically at the same time.
According to this structure, even if the movable body moves quickly in the direction of the arrow with the lateral movement means, the clamper (2) will not open due to the inertial force of the gripped car (IJ) (1). That is,
The cartridge (1) can be held in a completely gripped state by a guide (52) provided at the open end of the holder (c) and a clamper provided on the movable body.

Selectively take out the cartridge (1) stored in the stocker (1) and insert it into the playback device ( The main operation of this device is to return the cartridge (1) to its original position by inserting it into the cartridge (1) or vice versa. The important role of this device is to accurately store the disc information in the cartridge (1), and it is not good to subject it to shocks or extreme vibrations during transportation. It is also important to read a lot of information in a short time, and it is also an important function to increase the transport speed, that is, to shorten the access time of the cartridge (11).

Below - as an example, the cartridge (1a) shown in Figure 4
The operation of taking out and inserting it into the playback device (3a) will be explained. First, take out the cartridge (1 &) and install it for playback.

The insertion/ejection machine # (41) is moved until it faces and coincides with the center of the front of the cartridge (la) inside. At this time, the position is confirmed using a photoelectric sensor (not shown) using a scale with a slit. All use pulse motors, and the tip of the insertion/removal mechanism (4) is moved at a speed pattern that reduces vibration.Then, the swing motor of the gripping mechanism provided on the moving body is activated. and clamper (
At the same time as the motor G1) is opened, the movable body moves forward toward the cartridge.
) When the guide (52) provided at the front engages with the thickness direction of the cartridge, and then the sensor (64) detects the front of the cartridge (1 &), the forward movement stops. When the condition is released, the clamper ■ closes due to the force of the spiral spring inside the swing motor, and the cartridge (1&)
It engages with the locking parts provided on both sides of the cartridge (1&) and holds both front sides of the cartridge (1&).

The state is shown in FIG. Next, when the closed state of the clamper is confirmed by a sensor (not shown), the motor rotates in reverse to draw the cartridge (L&) from the open end of the holder (C) toward the closed end. At this time, the cartridge (

is rotated by 180 degrees. When all the movements are completed, the motor (b) is driven to advance the cartridge (1&). At this time, press the push button () provided on the top of the moving body.
6), so that the locking part of the clamper (2) has a gap with the locking part of the cartridge (la). This is to open the clamper ■ with a light force, thereby reducing the capacity of the swing motor.
When the cartridge (1a) moves forward and is inserted into the playback device (3), a sensor (
(not shown) operates, and the driving of the motor c11) is stopped. At the same time, the swing motor is energized and the clamper ■
opens. When the clamper is completely expanded, the motor (b) is then reversed to retract the gripping mechanism. Next, the swing motor is de-energized, the clamper (2) is closed, and the machine enters a standby state. When the recording or reproduction of the reproduction device (3) is completed, a command is issued to return the cartridge (1a) to its original position in the stocker (2). The operation at this time may be the reverse of the operation described above. However, the difference is that when the cartridge (l&) is inserted into the stocker (2), the sensor (65) provided at the rear of the stocker (2) detects the rear of the cartridge (1&), and the motor 01) is driven. By stopping the stocker (2), the stocker (2) is held in its position and will not protrude from the stocker (2) due to vibration or the like.

〔Effect of the invention〕

As described above, according to the present invention, when the cartridge is pushed into the insertion/removal mechanism, the contact part of the movable body is brought into contact with the front of the cartridge, and when the cartridge is pulled out, the mechanism is pressed.
Since the locking part of the clamper provided on the movable body and the recessed locking part of the cartridge are configured to be pulled by engaging, the power of the motor that expands the clamper can be reduced, and the structure of the gripping mechanism is simple. This has the effect of allowing a moving object to move at high speed.
