3 Slide the slide tab in the opening direction. At this time,
As shown in FIG. 6, the 3-4 contact switch is turned off in the detection unit DET, but since no power is supplied to the hard disk device, the Beeper sound is not generated from the 1-3 speaker. Next, the user slides the hard disk device in the direction of arrow removal in FIG. At this time, since the 3-3 electronic lock key is buried in the unlocked state, the hard disk device can be slid.

By the above operation, the hard disk device can be removed from the processing device main body.

Next, a description will be given of a case where the hard disk device is temporarily detachable from the processing device main body and the hard disk device is attached to the processing device main body while the hard disk device is removed from the main body.

First, in this state, the 2-4 LED is in the off state, and the user of the apparatus visually confirms that the processing apparatus main body is in a state where the hard disk device can be attached and detached. Next, the user slides the 4-4 slide type claw in the arrow opening direction in FIG. 4, then aligns the 4-2 positioning guide with the 3-2 positioning guide structure, and moves the hard disk device in the arrow mounting direction in FIG. Slide it.
At this time, since the 3-3 electronic lock key is buried in the unlocked state, the hard disk device can be slid. The hard disk device is slid until the 3-1 connector and the 4-1 connector are firmly connected, and finally the 4-4 slide type claw is slid in the arrow closing direction in FIG. 2 to fix the hard disk device to the processing apparatus main body.

Next, while the power source of the processing apparatus main body is ON and the hard disk apparatus is temporarily unremovable from the processing apparatus main body, let's remove the hard disk apparatus from the main body with the hard disk apparatus attached to the main body. The operation in such a case will be described.

First, in this state, the 2-4 LED is in a lighting state, and normally, the user of the apparatus confirms that the processing apparatus main body is in a state in which the hard disk device cannot be attached / detached by visually recognizing this. , The removal operation must be stopped. If the user does not confirm the 2-4 LED here, or for some reason 2-4L
When the warning by the ED is ignored, the user slides the 2-3 slide type claw in the opening direction.

Here, the 3-4 contact switch is turned off by sliding the slide type claws in the opening direction, and as shown in FIG. 6, the hard disk device is further supplied with power at this time. A beep sound for warning is generated from the three speakers. Again, if the user did not confirm the warning by the beep sound from the speaker, or if the warning was ignored for some reason,
The user next tries to slide the hard disk device in the direction of the arrow removal in FIG. However, at this time, the 3-3 electronic lock key protrudes from the bottom surface of the main body in the locked state and engages with the 4-3 electronic lock key receiving port, so that the hard disk device cannot be physically slid. As a result, in this state, the user cannot remove the hard disk device from the main body of the processing device.

Next, the operation when the hard disk device is temporarily unremovable from the main body of the processing device and the hard disk device is mounted on the main body of the processing device when the hard disk device is removed from the main body will be described. To do.

First, in this state, the 2-4 LED is in a lighting state, and the apparatus user visually confirms that the processing apparatus body is in a state where the hard disk cannot be attached / detached. I have to stop.

If the user does not confirm the 2-4 LED or if the user disregards the warning by the 2-4 LED for some reason, the user next moves the 4-4 slide type claw in the arrow opening direction in FIG. Slide to, then 4-2
Align the positioning guide with the 3-2 positioning guide structure and try to slide the hard disk drive.

However, at this time, since the 3-3 electronic lock key projects from the bottom surface of the main body in the locked state, the hard disk cannot be physically slid. As a result, in this state, the user cannot mount the hard disk device on the main body of the processing device.

As described above, in the present embodiment, the hard disk device removable state can be switched to the removable state and the non-removable state by switching the power supply state of the processing apparatus main body between the ON state and the OFF state.
