A device that has a mechanism that allows it to be inserted into or removed from a device.

There is.

An example of the device (2) is shown in FIG. 1, and an example of the device (2) is shown in FIG. 2.

In FIG. 1, reference numeral a denotes a storage table, and a plurality of information storage media are stored on the storage table a. C is an information reading/writing device, and has an insertion slot i for an information storage medium. The mechanism for moving the information storage medium is composed of an arm e, an arm drive device d, a holder, a holder drive g, and a drive screw f. In FIG. 2, reference numeral 0 indicates an operable storage table, which is driven by a storage table drive device q and a drive screw p. An information storage medium r is accommodated on the accommodating table 0.

S is an information reading/writing device, and an insertion slot V for the information storage medium r.
There is. A mechanism for inserting and removing the information storage medium r into the information reading/writing device s is composed of an arm U and an arm driving device t.

Traditionally, the conventional device (■) has operating parts (d, e,
Since the mass of h) is small, the drive device g can be made small, but
Move the arm e for moving the information storage medium to the position on the storage stand a where the selected information storage medium is to be extracted, then extract the information storage medium and insert the information reading/writing device C. the information storage medium must be inserted into the insertion port i. Next, after the information reading/writing device C reads and writes information from the information storage medium,
The information storage medium must be taken out from the information reading/writing device C, moved to return to its original position on the accommodating table a, and an operation must be performed to store the information storage medium at its original position on the accommodating table a. Therefore, it has the disadvantage that access time becomes longer.

In addition, in the device (3), the storage table 0 is moved so that the selected information storage medium r is at a predetermined position, and the information storage medium r that has arrived at the predetermined position is inserted into the information reading/writing device S by the arm U. However, after the information reading/writing device S reads and writes information from the information storage medium r, it takes out the information storage medium r and stores it in the original position of the storage table 0.
The access time is shorter than the device in (2). However, when the amount of information storage media increases, the mass of the information storage media and the storage platform increases, and the drive device for operating the storage platform also becomes larger. In addition, the driving speed also becomes slower. The device (2) has the disadvantage that the access time becomes longer when the capacity increases, and the disadvantage that the drive device becomes larger.

<Object of the Invention> In view of the above-mentioned matters, an object of the present invention is to provide a large-capacity information holding and retrieval device in which the opening force at the time of access is short.

Example The configuration of the present invention will be explained below with reference to the drawings.

A large-capacity information holding and retrieval device according to an embodiment of the present invention is shown in FIGS. 3 and 4.

FIG. 3 is a schematic perspective view of the large-capacity information holding search E% in this embodiment, and FIG. 4 is a front view thereof.

In the figure, 1 is a frame of the large-capacity information holding and retrieval device, and 2 is a rotatably provided storage table, which is rotated by a storage table rotation device 50. A plurality of information storage media 5 are accommodated in the accommodating table 2 . Further, reference numeral 3 denotes a rotatably provided holding stand, on which an arm driving device 40 for driving the information reading/writing device 20 and the arm 30 is attached. The information reading/writing device 20 is provided with a guide 22 for smoothly inserting the information storage medium 5. Further, 21 is an insertion slot for an information storage medium. Further, 41 is a screw for driving the arm 30. A claw 31 (see FIG. 4) is attached to the arm 30.

Further, IO is a holding table rotating device for rotating the holding table 3.

In the large-capacity information holding and retrieval device as described above, the storage platform 2
When one of the above information storage media 5 is selected, the selected one of the information storage media 5 is inserted into the insertion slot 2 of the information reading/writing device 20.
1, the storage table 2 and the holding table 3 are rotated in opposite directions by the storage table rotation device 50 and the holding table rotation device IO, respectively. Next, the arm 30 is moved in the direction B in the figure by the arm driving device 40, and the information storage medium 5 is inserted into the information reading/writing device 20, resulting in the state 5' indicated by the broken line in the figure.

After the information is read and written here, the information storage medium 5
A part of the information reading/writing device 20 protrudes from the insertion slot due to the mechanism of the information reading/writing device 20 itself. Therefore, the information storage medium 5 is detected by a detection means (not shown) provided on the arm 30.
It is detected whether or not the arm 30 is in contact with the arm 30. If they are in contact, a solenoid (not shown) rotates the claw 31 in the downward direction in the figure to grip the information storage medium 5.

On the other hand, if there is no contact, the arm 30 is moved by the arm drive device 40 in the direction B in the figure until it comes into contact with the information storage medium 5, and at the same time the contact is detected, the same type 3
Grab the information storage medium 5 at the .

Next, the arm 30 is moved in the direction C in the figure by the arm driving device 40, and the information storage medium 5 is stored in the original position on the storage table 2, and the operation is completed.

<Effects> As described above, according to the present invention, since the holding parts of the on-board information read/write device for storing information storage media move simultaneously, it is possible to obtain a large capacity information storage and retrieval device with extremely short access time. .
