First, when the cartridge 11 is inserted and fixed in the cartridge fixing mechanism 13, the cartridge fixing completion sensor 24 turns on and recognizes that the cartridge 11 is fixed (step 1). Detect whether the cartridge 11 has come out of the predetermined position (step 2).At this time, if the sensor of the light receiving section 21 detects a light-blocking state (Fig. 5), the drawer block 12 is removed. Since the drawer block 12 is detached, the process moves to the next step 3. When the drawer block 12 is detached, a display indicating that the drawer block 12 is detached is displayed on the display 23 (step 3), and the drawer stop section 1
8 instructs the motor control circuit 17 to suspend the magnetic tape drawing operation (step 4). After that, the drawer block 12 is removed from the cartridge 1 by a staff member or the like.
Attach it correctly to 1. After this installation, the process returns to step 1 to check the state of the cartridge 11 again.

On the other hand, if the sensor of the light receiving section 21 detects the transmission state (FIG. 4), the drawer block 12 is correctly attached, and the process moves to the next step 5. If the drawer block 12 is correctly attached, the display on the display 23 (if the drawer block 12 was removed last time, a message to that effect is displayed) is erased (step 5). Next, the motor 16 in the magnetic tape pull-out mechanism 14 is driven, the pin 15 of the magnetic tape pull-out mechanism 14 for pulling out the pull-out block 12 is coupled with the pull-out block 12, the magnetic tape is pulled out, and the magnetic tape running guide (not shown) is driven. The magnetic tape passes through the mechanism and is wound onto a take-up reel by a magnetic tape running operation (step 6).

By the way, after returning to step 1 after the staff's processing, check that the cartridge 11 is fixed again in step 1, and then remove the drawer block 1 in step 2.
Check the status of step 2, but this time the staff has installed it correctly, so step 5 and step 6 are executed, the magnetic tape is pulled out, wound around the take-up reel, and moved to the magnetic tape running operation to transfer it to the magnetic medium. Recording and reproduction of information is performed.

Therefore, in this embodiment, since a detection mechanism is provided to detect whether the drawer block 12 has come off from the predetermined position of the cartridge 11, if the drawer block 12 has come off, it will notify you of this fact and temporarily stop the magnetic tape pullout operation. Since the lid is now able to be stopped temporarily, the magnetic tape can be run normally by installing the drawer block 12 correctly by the staff, etc., and the operation of the device can be resumed quickly. Effective.

Incidentally, if a mechanism is provided to automatically attach the detached drawer block 12, automatic operation becomes possible.

Furthermore, when the magnetic tape is rewound into the cartridge 11, it is detected whether or not the pull-out block 12 is out of its predetermined position.Since the pull-out block 12 is always in the correct position when the cartridge 11 is first used, the magnetic This is effective because the operation of the tape device is ensured.
