And a switch means for supplying a signal for driving the tray 3 to the main body side connection terminal 25a of the apparatus main body 21 connected to the disk side connection terminal 4a of the hard disk unit 4 for inputting / outputting a signal to the hard disk unit 4 and supplying power. A slide switch 6, a power supply circuit 23 for supplying power to the hard disk unit attaching / detaching device (the device main body 21 and the hard disk unit 4: hereinafter, abbreviated as the attaching / detaching device), a control circuit 24 for controlling the entire attaching / detaching device, It has a connection terminal 25a so that communication between the control circuit 24 and the hard disk unit 4 is possible. And a relay printed circuit board 25 for the exchange.

The drive means includes a worm 1b press-fitted into a rotatable shaft 1a in the tray drive motor 1, a reduction gear 2 rotating about a support shaft 2c, and a rack 3a formed on one side of the tray 3. It is composed of A worm wheel 2a that meshes with the worm 1b of the tray drive motor 1 is formed below the reduction gear 2, and a flat gear 2b that meshes with the rack 3a of the tray 3 is formed below the reduction gear 2. The worm wheel 2a and the spur gear 2b are integrally formed. The rotational force of the tray drive motor 1 is transmitted to the rack 3a while being reduced by the reduction gear 2, so that the tray 3 is slid in the direction A.

As shown in FIG. 2, the reduction gear 2 is urged upward by a compression spring 7, and the spur gear 2b normally meshes with the rack 3a of the tray 3 as indicated by a solid line. I have. In addition, a hole 21a is provided in a case portion 21b of the apparatus main body 21 at a location where the drive means is provided from the outside, and a rod-shaped body B or the like is inserted therefrom. Reduction gear 2

Further, when the tray 3 is inserted to the mounting position, a signal is switched by the protrusion 3c of the tray 3, and the mounting switch 5b detects that the tray 3 is mounted.

In the hard disk unit attaching / detaching apparatus configured as described above, the control circuit performs a control operation as shown in FIG. First, in step # 1, it is confirmed whether or not the slide switch 6 for instructing the ejection or mounting of the hard disk unit 4 is pressed. If the slide switch 6 is pressed in a state where the tray 3 and the hard disk unit 4 are at the mounting position, the mounting switch 5b detects that the tray 3 is at the mounting position at the time of proceeding to step # 2. Next, in steps # 3 and # 4, if the hard disk unit 4 is being driven, a drive stop command is output to the hard disk unit 4 to stop the operation of the hard disk unit 4.
Then, when it is detected that the predetermined time has elapsed, the power supply to the hard disk unit 4 is stopped (Step #).
5, # 6) Then, the tray drive motor 1 is rotated forward until the ejection switch 5a detects the protrusion 3c of the tray 3. Thereby, the disk-side connection terminal 4a of the hard disk unit 4 is detached from the main-body-side connection terminal 25a of the apparatus main body 21, and the tray 3 and the hard disk unit 4 are automatically moved to the discharge position.

On the other hand, if the slide switch 6 is pressed while the tray 3 on which the hard disk unit 4 is mounted is at the take-out position, the steps # 2 to #
10, the tray 3 is operated by the discharge switch 5a.
Is detected to be at the discharge position. Next, steps # 11 to # 13 are executed, and the tray drive motor 1 is
The rotation is reversed until the mounting switch 5b detects the protrusion 3c of the tray 3. As a result, the tray 3 and the hard disk unit 4 are automatically moved to the mounting position, and the disk connection terminal 4a of the hard disk unit 4 is connected to the main body connection terminal 25a of the apparatus main body 21. At this time, similarly to the state where the tray 3 is at the discharge position, the state where the input / output of the signal from the apparatus main body 21 to the hard disk unit 4 and the power supply are not performed is maintained. Thereafter, when it is detected that a predetermined time has elapsed, the power supply to the hard disk unit 4 is started (steps # 5 and # 6), and then the driving of the hard disk unit 4 is started.

According to this configuration, the hard disk unit 4 mounted on the tray 3 can be automatically attached and detached and moved only by operating the slide switch 6, and the hard disk unit 4 can be easily attached and detached. In addition, since there is no manual removal operation of the hard disk unit 4 as in the related art, an unreasonable load due to an erroneous operation is not applied.

When the hard disk unit 4 is ejected from the apparatus main body 21, the operation of the hard disk unit 4 is stopped and the power supply is stopped, and after the hard disk unit 4 is in a safe state, the tray 3 is moved. Since the discharging operation is performed, troubles such as breakage of the hard disk unit 4 due to the movement of the hard disk unit 4 during driving of the hard disk unit 4 do not occur.

Further, when the hard disk unit 4 is ejected from the apparatus main body 21, the hard disk unit 4
After the operation stop command is executed, after a time delay, the power supply to the hard disk unit 4 is stopped, and then the tray drive motor 1 for driving the tray 3 is started. To the hard disk unit 4 from the device body 21 side.
In a safe state where power is not supplied to the
The hard disk unit 4 can be separated from the side. As a result, problems such as breakage of the hard disk unit 4 can be more reliably prevented, and reliability is improved.

When the hard disk unit 4 is mounted on the apparatus main body 21, the tray drive motor 1 is first activated to move the tray 3, and the hard disk unit is mounted on the apparatus main body, that is, the movement of the tray 3 is completed. After that, the operation command of the hard disk unit 4 is executed, so that the hard disk unit 4 does not move, and the hard disk unit 4 is not moved, so that troubles such as damage of the hard disk unit 4 do not occur.

When the hard disk unit 4 is mounted on the apparatus main body 21, after the tray 3 is moved and the connection terminals 4a and 25a are securely connected to each other, the power supply to the hard disk unit 4 is delayed. Since the supply is started and thereafter the operation command of the hard disk unit 4 is executed, the power supply from the apparatus body 21 to the hard disk unit 4 is safe without causing a short circuit between the connection terminals 4a and 25a. The hard disk unit 4 is started to be driven in a stable state, and the reliability is improved.

If the tray 3 on which the hard disk unit 4 is mounted is located between the discharge position and the mounting position, and neither the discharge switch 5a nor the mounting switch 5b is in the ON state, the slide switch is used. When the button 6 is operated, the same discharging operation as described above may be performed so as to prevent a short circuit between the connection terminals 4a and 25a, but this is not restrictive. Further, a switch for giving a discharge instruction and a switch for giving a mounting instruction may be separately provided.

Further, when an outlet is connected to the apparatus main body 21 and the slide switch 6 is pressed in a standby mode in which the main power is off, the main power is automatically turned on.
When the tray 3 is configured to be operated to the mounting position or the discharging position, the trouble of turning on the main power can be omitted, and after the main switch is turned off after the slide switch 6 is operated, the main power is turned off again. There is no need to operate the slide switch 6 or the like, and the operability is improved.

In the above configuration, when the hard disk unit 4 attached to the apparatus main body 21 is taken out, if the hard disk unit 4 cannot be taken out by the tray drive motor 1 due to the failure of the apparatus main body 21, the hole of the apparatus main body 21 is removed. By inserting the rod-shaped body B or the like from 21a and pressing down the reduction gear 2 from above, the drive force transmission path between the worm 1b and the worm wheel 2a or between the spur gear 2b and the rack 3a is interrupted, so that the tray 3 is manually operated. The slide becomes possible, and the removal and attachment of the hard disk unit 4 can be performed manually.

Here, in the above-described embodiment, a case has been described in which the operating means for interrupting the driving force transmission path is not provided, but instead, the following transmission path interrupting means may be provided. Good.

That is, as shown in FIG. 4, a switching arm 8 is provided as a transmission path blocking means which rotates about a fulcrum 8a, and the reduction gear 2 is controlled by a gear pressing portion 8b provided at the end of the switching arm 8. It is configured so that it can be pressed from above.

According to this configuration, when the hard disk unit 4 mounted on the apparatus main body 21 is taken out and the hard disk unit 4 cannot be taken out by the tray drive motor 1 due to the failure of the apparatus main body 21, the switching arm 8 is moved to the arrow. In the counterclockwise direction and rotate counterclockwise to hold down the reduction gear 2 against the compression spring 7 from above.
b and the worm wheel 2a or between the spur gear 2b and the rack 3a by cutting off the driving force transmission path.
Can be manually slid, and the removal and attachment of the hard disk unit 4 can also be performed manually. Further, since it is not necessary to search for the rod-shaped body B as in the above-described embodiment, the convenience is improved.

Further, as shown in FIG. 5, a concealed door 9 which pivots around the fulcrum 9a to cover and hide the operation portion of the switching arm 8 from the outside, and a switch attached to the tip of the concealed door 9 A door state detection switch 10 which can be freely contacted with the holding portion 9b and detects opening and closing of the hidden door 9 may be provided.
The door state detection switch 10 is turned on when the hidden door 9 is closed
It turns off when opened.

In this configuration, when the hard disk unit 4 cannot be taken out by the tray drive motor 1 due to the failure of the apparatus main body 21, when the hidden door 9 is opened for the purpose of blocking the drive force transmission path by the switching arm 8, Since the door detection switch 10 is switched from ON to OFF, this signal is detected, and the control circuit 24 issues a command to stop the operation of the hard disk unit 4. As a result, the hard disk unit 4 stops driving the head and the disk, so that when the switching arm 8 is operated thereafter, the safe removal of the hard disk unit 4 becomes possible.

Although not shown, the worm wheel 2a and the spur gear 2b of the reduction gear 2 are formed as separate members, and a force of a predetermined value or more is applied between these members from the tray drive motor 1 side to the tray 3 side. A clutch mechanism for preventing transmission may be provided. According to this configuration, when the tray 3 is forcibly fixed during the operation of moving the tray 3, or when the tray 3 is moved from the mounting completed position or the ejection completed position, the movement of the tray 3 is performed. Even when an excessive load is applied when the operation is restricted, the clutch mechanism slips and no extra load is applied to the downstream parts.
Therefore, according to this configuration, it is possible to prevent the driving force transmission path and the connection terminals 4a and 25a from being damaged, thereby improving the reliability.

As shown in FIG. 6, the removable hard disk unit 4 may be housed in the cartridge 11, and the cartridge 11 storing the hard disk unit 4 may be installed in the tray 3. Here, as the cartridge 11, the upper case 11a and the lower case 11b can be docked, and the connection terminal 4a of the hard disk unit 4 is

Further, the portions of the upper case 11a and the lower case 11b other than the unit holding portion 11c are made of a material having relatively large rigidity, while the unit holding portion 11c is made of an elastic body which easily absorbs vibration.

According to this configuration, the hard disk unit 11 can be handled while the hard disk unit 4 is housed in the cartridge 11, and the convenience is improved. In addition, since the vibration when the hard disk unit 4 is attached and detached is absorbed by the unit holding portion 11c of the cartridge 11, the vibration when moving is hardly transmitted to the hard disk unit 4, and the damage due to the vibration of the hard disk unit 4 is more surely prevented. Can be prevented.
