Abstract

PURPOSE:To secure the safety of information recorded on an optical disk cartridge in a device by adopting such structure to the device that the cartridge cannot be taken out at the time of turning on a key switch. CONSTITUTION:When a key switch 11 is turned on, a shutter is opened by the depression of a shutter switch 10 by an operator, since the circuit of a shutter motor 12 and a control circuit 13 is closed, and the operator can take a cartridge 3 out of the device 4. When the key switch 11 is turned off, the circuit in the shutter motor 12 and the control circuit is opened, and a current is not supplied to the shutter motor 12 even when operator depresses the shutter switch 10 and the shutter is not opened, and therefore, the cartridge is not taken out. Thus, the cartridge is safely preserved.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a large-capacity optical disk storage device.

[Conventional technology]

FIG. 6 is a perspective view of a conventional large-capacity optical disk storage device disclosed in, for example, Japanese Unexamined Patent Publication No. 64-42058, and FIG. 7 is a front view of a conventional large-capacity optical disk storage device disclosed in the same publication. It is. In Fig. 6, (1) is the main body of the large-capacity optical disk storage device, (2) is a storage shelf that stores several W optical disk cartridges, and (3) is the information storage shelf that is removably attached to the storage shelf (2). (4) is a recording/playback device that records and plays back information on the optical disk; (5) is a cartridge that stores an optical disk as a medium for recording/playback; (5) is a cartridge between the recording/playback device (4) and the storage shelf (2).

Insert the cartridge (3) into the target recording/reproducing device (4) or storage shelf (2).

[Problems that the invention helps solve]

Conventional large-capacity optical disk storage devices are structured as described above, so when the cartridge (3) inside the device is taken out, if the device is waiting for the shirt-taper switch αO to be pressed, the shirt-taper There is a possibility that an unspecified number of people who can press the button αO can take it out. For this reason, there are problems in ensuring the safety of information, such as the possibility that the cartridge, which records important information inside the device, may be taken out by the user without permission or destroyed.

This invention was made in order to solve the above-mentioned problem, and has a large structure that allows the cartridge stored inside the device to be removed only by a specific person authorized by the user or in specific cases. The purpose is to obtain a capacity optical disk storage device.

[Means for solving problems]

A large-capacity optical disk storage device according to the present invention has a key switch, and the optical disk cartridge can be removed from the cartridge loading/unloading port only when the key switch is in the ON state.

[Effect]

In the large-capacity disk storage device of the present invention, when the key switch is turned OFF, the shirt sleeve does not open and the cartridge cannot be taken out of the device, allowing the cartridge to be stored safely.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figures to FIG. 3, αD is a key switch. 0 is a shirt opening/closing motor, (13 is a control circuit, and a4 is a t source.

Next, we will explain the operation of the 0 storage shelf (2) and the recording/playback i.
N When taking out the cartridge (3) in (4) to the outside of the device, the transport machine moves to the storage shelf (2) where the target cartridge is located or to the recording/reproducing device (4) from which the target cartridge (3) was ejected. IJW bearing (
6), and the gripping section (50 moves forward to grip the cartridge (3), then retreats and pulls it into the conveyor (5). Move the tray (7) to the front of the tray (7a). 3
), then release and retract. The feeding/discharging mechanism (7) into which the cartridge (3) is inserted into the tray (7 turtle) is turned over 180 degrees to direct the mouth of the tray (7&) toward the feeding/discharging port (8). If the key switch α is ON in this state, the circuit between the shutter motor 0 and the control circuit α3 is closed, so when the operator presses the shirt switch α0, the shutter (9) opens and the operator presses the cartridge (3) It is possible to take out b. But key switch 0 is OFF
When the voltage is VC, the circuit between the shutter motor 0 and the control circuit is opened, and even if the operator presses the shutter switch, current is not supplied to the shutter motor (self) and the shutter (9) does not open. Conversely, when inserting the cartridge (3) into the storage shelf (2) or recording/playback device (4) from outside the device, the supply/ejection mechanism (
7) with the opening of the tray (7 &) facing the supply/discharge port (8), the conveyor (5) in front of the tray, and waiting for the cartridge (3) to be inserted, the operator inserts the shirt When switch αO is pressed, if key switch 0 is ON, the circuit with control circuit O is closed, so shirt starter motor 0 operates, so shirt starter (9) opens and cartridge (3) is inserted. If the 0 key switch is OFIF, the circuit with the control circuit a3 is open, so the shutter will not open and the operator can open the cartridge (3).
) When the operator inserts the cartridge (3) into the tray (7) from the supply/discharge port (8) and presses the shirt-taper switch QQ, the shirt-taper (9) closes and the supply/discharge mechanism (
7) is reversed so that the tray (10) faces the conveyor.The conveyor (5) pulls in the cartridge (3) and places the cartridge (3) in the target recording/reproducing device (4) or storage shelf (2).
Insert.

Storage shelf (2) inside the device and record playback! ! The cartridge exchange (3) between (4) and (3) is the same as before.

In the above embodiment, the key switch 0 is installed in the circuit that supplies current to the shirt starter motor (self) that opens and closes the shirt starter (9).
The operation of the shirt starter was restricted by opening and closing the circuit, but as shown in Figure 4, the key switch (self) was installed in a circuit independent from the drive circuit of the shirt starter motor (6). O N , (VP may be detected by the control circuit O, and the operation of the shirt shutter may be limited by a relay or the like provided in the control circuit, or may be limited by software. Also, in this case, When removing the cartridge (3) from the outside of the device, key switch 0 is set to 071.
If it is in that condition, it is impossible to remove the shirt holder (9) or the supply/discharge mechanism (
7) does not operate, and when inserting the cartridge (3) into the interior, its operation is not restricted regardless of whether the key switch is in the 0υ shape, allowing for fine control. In addition, a numeric keypad for entering numbers is provided in place of the key switch as shown in Figure 6, and when taking out the cartridge, the user enters the password, and if the entered number is equal to the preset number, the cartridge is removed. Rather than allowing this, the software of the control circuit 0 may be used to control it.

In the above embodiment, a large-capacity optical disk storage device has been described, but instead of an optical disk cartridge, a VTR, cassette magnetic tape, magneto-optical disk cartridge, magnetic disk cartridge, 7-bit disk, etc. can be used as a device that automatically exchanges the recording medium. [Effects of the Invention] As described above, according to the present invention, when an optical disc cartridge stored inside a large-capacity optical disc storage device is taken out from the device, the key switch is turned ON. I was worried that I couldn't do it without it, so the key switch was 071.
In the F state, the optical disc cartridge cannot be removed unless the user has the key to the key switch, which has the effect of ensuring the safety of the information recorded on the optical disc cartridge inside the device.
