SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the medium insertion mechanism in conventional automatic selection automatic processing devices and to provide a medium insertion mechanism that allows a disk cartridge to be smoothly inserted and removed.

According to the present invention, in a medium insertion mechanism comprising a conveyor for gripping and transporting a flat disc cartridge, and a storage group for storing the disc cartridge, the width of the disc cartridge and the height of the stone ,
a storage having a guide frame slightly wider than the above, a guide wall that guides approximately only the rear half of the disk cartridge; a gripping means for grasping and inserting/extracting the disk cartridge; and a gripping means for guiding the disk cartridge; and a guide frame that is slightly wider than the width and height of the disk cartridge, and a guide wall fr that guides only approximately the front half of the disk cartridge. A medium insertion mechanism is obtained which is characterized in that the medium is inserted and removed while being guided by a guide wall of either the storage bin or the conveyor.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a media inserter which is an embodiment of the present invention.

In FIG. 1, one embodiment of the present invention includes a disk cartridge storage 12 having a guide frame 12a-12ci provided with a guide wall 21 that completely guides only approximately the rear half of the disk cartridge 13, and a disk cartridge 13 that is gripped. Guide frames 36a to 3,6cf equipped with a gripping means 31 for inserting and removing, a guide frame 36 for guiding the disk cartridge 13, and a guide wall 35 for guiding only approximately the front half of the disk cartridge 13: a supporting portion 36 provided. A transport mechanism 11 having a transport mechanism 11 is included.

Q storage 12 for storing disk cartridges 13
It consists of a plurality of storage compartments stacked vertically in one or more stages and installed in large numbers horizontally as well. In this storage 12, disk cartridges 13 are arranged vertically or horizontally at equal intervals. In addition, in the case of something like a flombi disc, the discs may be arranged horizontally. Furthermore, guide walls 21 each having a length of about one-half of the disk cartridge are installed at equal intervals on the back side of this storage, and are used to regulate and position the disk cartridge in the width direction. This guide wall 21 is 0.5 to 0.0 mm wider than the width of the disk cartridge.
Seven gaps are installed at equal intervals. - The tensile conveyance machine 11 is supported by a lower rail 41 and an upper rail 42 installed parallel to the storage 12, and the grip part 3 moves in the horizontal direction.
0, and this gripping portion 30 is configured to wrap around the disk cartridge and be guided by a guide rod 38 and moved vertically by a ball screw 37 up and down.

Further, the gripping portion 30 is provided with a U-shaped support portion 36 for supporting the disk cartridge, and a gripping means (hand) 31 for gripping the cartridge 13, and this gripping means 31 is provided with a ball screw 32. The support part 36 is configured to reciprocate toward the storage 12 to insert and remove the disk cartridge 13 from the storage 12, and the support part 36 has guides 935 on the upper and lower rear sides of the support part 36, respectively. , installed below.

As a normal operation, the conveying machine 11 is positioned in the horizontal direction and the vertical direction by the hem motor 40 and the Y motor 39, respectively, to the position of one disk cartridge in the storage, and then comes to rest. Next, the opening means (hand) 31 opens the hangar 1 by means (not shown) of the Z motor 34.
It moves forward towards 2. When the gripping means (hand) 31 moves forward, it enters into the opening of the storage, and the gripping means (hand) is closed by means not shown and grips the rear &J 14' of the disk cartridge 13. 2 motors 3 again
4 is biased and drawn into the grip 30. Figures 2 and 3 show the operating state of inserting and removing the IJ (data car) from the storage compartment.

In FIG. 2, in this embodiment, the hand 31 moves the arrow 2
Although it is pulled out in the direction of 4 and inserted into the gripping part 30,
The disk cartridge 13 is regulated by the guide wall 21 of the storage 12, but not by the guide wall 35 of the grip part 30.

Therefore, if the center line 23 of the storage 1a12 and the center line 50 of the gripping part 30 are well aligned as shown in the figure, the end of the disk cartridge can easily become oblique due to the slight gap between the guide wall 21 and the disk cartridge 13. With 36, it's almost not difficult.

Next, when the disk cartridge 13 is further retracted, the terminal end 36 of the disk cartridge 13 is shown in FIG.
has already deviated from the regulation of the guide wall 21 and is regulated only by the guide wall 35, and is equal to the pull. In order to provide flexibility in the movement of the hand 31 during these series of movements, the guide 33 and the ball screw 32 are elastically deformed as shown in FIG. 1 so that the hand 31 can be pulled out more smoothly.

In this embodiment, if the gap between the disk cartridge 13 and the guide walls 21 and 35 is t +3.7 +am, then in the conventional technology, if there is a center deviation of 0.7 cm, it will be difficult to insert or remove the center, but if the center is about 2.51 cm, it will be difficult to insert or remove the center. It can also handle deviations. In this embodiment, the guide wall is provided in the width direction of the disk cartridge, but this method can also be applied in the vertical direction. In this embodiment, as shown in FIG. 4, the upper and lower guide frames 12a and 12cK of the storage 12 are tapered with a depth of approximately one-half the length of the disk cartridge.
5, and upper and lower guide frames 36a of the gripping portion 30.

Tapers 51 and 52 are provided at 36c. With this structure, even if the vertical centers M27, 53 are shifted, the disk cartridge can be inserted and removed smoothly as described above.

The present invention has a structure in which the guide of the hangar and the transport section is (-1), which is approximately half the length of the ice space cartridge. This has the effect that the disc cartridge can be inserted and removed smoothly even if the disc cartridge is slightly misaligned.
