Thus, a predetermined cartridge is installed in the disc recording and reproducing apparatus 104.

Since the cartridge insertion mechanism in the conventional disk storage device is configured to support sliding both sides of the cartridge with the clamper as described above, a large power is required when opening the clamper, and the capacity of the motor must be increased, and the cartridge When gripping and releasing, the stopper needs to be moved back and forth at the same time as the clamper is opened and closed, and the structure of the gripping mechanism is complicated. There was a problem that the moving body is difficult to move.

In the conventional holding device, when the stopping device is suddenly stopped while moving the holding device in the clamped direction, the clamper is widened by the inertial force of the gripper, and the clamping member is peeled off the clamper, and the clamper may be out of the clamp position. It is necessary to constrain the gripping body by means of, and there is a problem that the whole device becomes large.

In addition, the conventional disk storage apparatus detects and stops the stop position of the forward movement by the same sensor attached to the front of the support, even when the cartridge insertion mechanism removes the cartridge from the stocker or the recording / reproducing apparatus, or inserts it into the stocker. If the relative positional relationship with the recording / reproducing device is misaligned, the forward movement distance may be too long to push the cartridge excessively, or the cartridge may be too short to hold the cartridge. Therefore, a rigid positional relationship must be obtained. There is a problem that it is necessary to increase the rigidity of the support material such as a stocker, and work is difficult in order to obtain accurate dimensional accuracy in the front and rear directions.

In the conventional disc storage device, when a cartridge in the disc recording and reproducing apparatus is exchanged with another cartridge, the cartridge in the disc recording and reproducing apparatus is discharged first, and the cartridge is composed of a carrier, a guide rail, a vertical motor, and the like. The conveying mechanism is accommodated in the storage shelf, and then the desired cartridge in the other storage shelf is taken out, then conveyed to the cartridge recording and reproducing apparatus by the conveying mechanism, and allowed to stand, and then put into the apparatus. In order to replace, the up-and-down motion by the conveyance mechanism increased, and as a result, the time required was long.

This is to make the S dimension as small as possible, to make the support 28 as small as possible to reduce the load of the cantilever support, and to make the whole apparatus of the present invention small. In the figure, a pair of clampers 40 are attached to the link 77 freely with the pins 85 in the form of a sands position between two sheets of thin plates. It is attached freely by rotation. The link 77 is connected to the rocking lever 66 with a pin 83, and in the drawing, the rocking lever 66 is rotated by the spring force of the rocking motor 44 in the direction of arrow G, and the stopper 86 In the abutting state, the center of rotation of the swing lever 66 and the center of the pin 83 and the center of the pin 84 are arranged in a straight line. This is a toggle link structure that simultaneously opens and closes the left and right clampers 40 symmetrically. According to this structure, even if the moving body 29 is quickly moved in the direction of the arrow K by the horizontal moving means, the inertia force of the cartridge 1 held by The clamper 40 is not opened by this. That is, the cartridge 1 can be supported in a completely gripped state with the guide 52 provided at the open end of the support 28 and the clamper 40 provided at the movable body 29.

8 shows a state in which the clamper 40 is opened by rotating the swing lever 66 by a certain amount in the arrow J direction. Numeral 76 is a pusher, which is inserted into the stocker 2 and the reproducing apparatus 3 while pushing the front part of the cartridge 1 to the front face.

The operation will be described below. The main operation of the device is to selectively take out the cartridge 1 housed in the stocker 2, insert it into the reproducing apparatus 3, or vice versa to return the cartridge 1 to its original position. It is also important that the device accurately stores the disc information in the cartridge 1, and it is not good to give an impact or intense vibration during conveyance. It is also important to read a lot of information in a short time, and it is also an important function to increase the conveyance speed, that is, shorten the access time of the cartridge 1.

As an example, an operation of taking out the cartridge 1a shown in FIG. 4 and inserting it into the reproducing apparatus 3a will be described. First, a command is input to the apparatus to take out the cartridge 1a and insert it into the reproducing apparatus 3a. Then, the lifting motor 10 and the horizontal movement motor 31 are driven by a controller (not shown) built in the apparatus, and the operation center of the insertion / removing mechanism 4 is the center of the front of the cartridge 1a in the stocker 2. The insertion and removal mechanism 4 is moved until it coincides with, and the positioning is performed by the slit scale and the photoelectric sensor (not shown), and the motors all use a pulse motor. The tip end of step (4) is moved in a speed pattern such that the vibration is low, and then the swing motor (44) of the gripping mechanism provided in the movable body (29) is operated, the clamper (40) is opened, and the motor (31) is opened. Driven, the movable body 29 is advanced toward the cartridge, first the guide 52 provided in front of the movable body 29 is engaged with the thickness direction of the cartridge, and then the front of the cartridge 1a is detected by the sensor 64. Forward movement stops. The energized state of the rotor 44 is released, and the clamper 40 is closed by the force of the spiral spring in the swinging motor to engage with the engaging portions provided on both sides of the cartridge 1a, and at the same time to support both sides of the front portion of the cartridge 1a. do.

The state is shown in FIG. Subsequently, when the closed state of the clamper 40 is confirmed by a sensor (not shown), the motor 31 reversely rotates and pulls the cartridge 1a toward the occluded end from the open end of the support 28. At this time, the cartridge (1a) is moved while the horizontal position is maintained by the guide 53 provided in the open end of the support (28). When the cartridge 1a is drawn to the position indicated by the dashed-dotted line in FIG. 2, the motor 10 and the motor 23 are driven to operate the center of the insertion / removing mechanism 4 at the center of the insertion opening of the regeneration device 3. Move until the position matches. During this movement, a command for selecting the front and back surfaces of the cartridge 1a is given, and if necessary, the motor 44 is driven so that the insertion / removal mechanism 4 is rotated by 180 ザ. When all the movement is completed, the motor 31 is driven to advance the cartridge 1a. At this time, the cartridge 1a is pushed by the pusher 76 provided on the upper portion of the movable body 29, and the latching portion of the clamper 40 is formed to have a gap with the locking portion of the cartridge 1a. . This is to open the clamper 40 with a light force, and to reduce the capacity of the swinging motor 44 accordingly. When the cartridge 1a is advanced and inserted into the reproducing apparatus 3, a sensor (not shown) installed in the reproducing apparatus 3 acts to stop the driving of the motor 31. At the same time, the swinging motor 44 is energized to open the clamper 40. When the spreading of the clamper 40 is completed, the motor 31 is then reversed to retract the holding mechanism. Subsequently, the energization of the swinging motor 44 is released to close the clamper 40, and the standby state is reached. When the recording or reproducing of the reproducing apparatus 3 is completed, a command to return the cartridge 1a to the original position of the stocker 2 is issued. The operation at this time may be reversed to the operation described above. However, the difference is that when the cartridge 1a is inserted into the stocker 2, the sensor 65 provided at the rear of the stocker 2 detects the rear portion of the cartridge 1a, and stops the driving of the motor 31. It is to let. In addition, the position of the cartridge 1a is maintained by the jersey spring 87 provided in the stocker 2, and it is not pushed out of the stocker 2 by vibration or the like.

Next, an embodiment of another gripping apparatus of the present invention will be described with reference to the drawings.

FIG. 9 is a front view of the gripping apparatus, and FIG. 10 is a sectional view taken along the line X-X of FIG. 2 showing the gripping mechanism.

You can respond simply if different.

The stopper 86 for restricting the rotational angle of the swing lever 66 is fixed. However, if the adjustment screw is attached to the clamper and the adjustment screw and the swing lever are brought into contact with each other, the assembling becomes easy. In addition, the provision of an elastic agent at the contact portion of the clamper 40 in contact with the gripping member and the stopper 86 in contact with the swing lever 66 protects the contact surface and prevents noise.

In the present embodiment, the disk storage device has been described. However, the disk storage device may be used for a cassette holding device of an audio product or an automatic warehouse arrangement.

In addition, when used in the hand portion of the robot, as well as assembly of parts or handling means has the same effect as the above embodiment.

In the present embodiment, it has been described that the guide 52 is engaged in the thickness direction of the cartridge 1, but when the grip portion of the clamper 40 is combined with the shape of a person, the gripped body is to be embraced. Guide 52 has the same effect even without installation.

The figure shows a state in which the pinion 25 attached to the shaft end of the motor 23 is rotated to engage the gear 26 to invert the insertion and removal mechanism 4 in the direction of the arrow P. FIG. The stopper 78 attached to the support 28c is held in position by an adjusting screw 82 attached to the horizontal movable table 5. At this time, the sensor 79 attached to the stopper 78 is adjusted with the adjustment screw 81 so as to be in a state where the inverted position is detected. Here, the reason why the center position N point of the inverter is slightly leftward from the inversion center M point is explained. This means that the center position is on the left side, and the force for always rotating the inverted body in the direction of arrow P is acting, and the adjustment screw 82 is always in contact with the stopper 78, for example, the cartridge 1 In the operation step of inserting into the stocker 2, when the vibration comes in from the outside of the device, the reverse position is moved so that the tip of the cartridge 1 collides with the stocker 2. To prevent this, the design of the device is centered at the position shown in the inversion center.

FIG. 11 is a schematic view showing the inverted state in FIG. 10. Since the center is to the right of the center of inversion after inversion, the stopper 78 always comes into contact with the adjusting screw.

The holding mechanism 40a provided in the movable body 29 is shown in FIGS. 7 to 10, and its configuration and operation are as described in the above embodiments.
