Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a mounting structure of a device bay unit according to an embodiment before an ejection operation is performed, FIG. 2A is a plan view seen from a direction of an arrow A in FIG.
FIG. 2B is a side view of FIG.
FIG. 2C is an enlarged view of a portion C in FIG.

In the structure shown in FIGS. 1, 2 (a), 2 (b), and 2 (c), a movable claw (engaging portion) n provided displaceably on the personal computer main body side is connected to the device bay unit a.
The operation of removing the device bay unit a from the groove (engaged portion) f provided on the side surface and the operation of applying an external force in the direction of the arrow e to the device bay unit a are linked, so that the device bay unit a can be removed by one operation.

The eject mechanism 1 includes a rotating lever h for applying an external force (a pushing force) in the direction of arrow e to the back of the device bay unit a, an eject bar j connected to the rotating lever h with a pin, and an eject bar j. And a spring p for urging in the opposite direction. The eject bar j is disposed so as to be located on the side of the device bay unit a. When the tip is pushed, the eject bar j moves in the direction opposite to the direction in which the device bay unit a is taken out, and rotates the rotation lever h.

Below the eject bar j, a rack and pinion mechanism k comprising a rack provided on the eject bar j side and a pinion rotatably supported at a fixed position is provided. A gear m is provided so as to mesh with the pinion of the mechanism k. The gear m is provided with a movable claw n that catches in a groove f on the side surface of the device bay unit a. Here, a gear m having a rack and pinion mechanism k and a movable claw n constitutes an engagement release mechanism.

In this structure, the spring p
The eject bar j, the rotation lever h, and the rack
The pinion mechanism k and the gear m are held in the state shown in FIG. The state of FIG. 2 indicates that the connection between the eject bar j and the rotation lever h is in the state of FIG. 2C.

FIG. 3 is a perspective view showing a state where the eject bar j has begun to be pushed in the direction of arrow q from the state of FIG. 2, and FIG.
3 is a plan view seen from the direction of arrow d in FIG. 3, and FIG.
4 (c) is a side view as viewed from the direction of arrow e in FIG.
FIG.

As shown in FIGS. 4A and 4B, the pinion of the rack and pinion mechanism k rotates in the direction of arrow r when the eject bar j moves in the direction of arrow q from the state of FIG. , And the gear m rotates in the direction of arrow s. As a result, as shown in FIG. 4B, the movable claw n comes out of the groove f of the device bay unit a.

In this state, as shown in FIG.
Since the eject bar j moves along the straight groove t of the rotation lever h, the rotation lever h does not move. Accordingly, it is possible to provide a time lag between the operation of removing the movable claw n from the groove f on the device unit a side and the operation of pushing out the device bay unit a from the back surface to take out the device bay unit a. The operation of detaching the movable claw n can be performed independently, and the device bay unit a can be reliably prevented from falling off.

Next, FIG. 5 is a perspective view showing a state where the eject bar j is further pushed in the direction of arrow q from the state shown in FIG. 3, and FIG. 6 (a) is a plan view seen from the direction of arrow in FIG. FIG. 6 (b) is a side view of FIG.
FIG. 7C is an enlarged view of a portion A in FIG. 6A.

When the eject bar j is further pushed in the direction of the arrow q, as shown in FIGS. 6A and 6B, the pinion and the gear m of the rack and pinion mechanism k are moved in the directions of the arrows r and s, respectively.
Rotate further in the direction. And the rotating lever h is shown in FIG.
As shown in (a) and (c), the eject bar j rotates in the direction of the arrow w by moving in the direction of the arrow q, and pushes out the device bay unit a in the direction of the arrow e.

That is, by one operation of pushing the eject bar j in the direction of the arrow q, the movable claw n which has prevented the device bay unit a from dropping is removed from the groove f (disengagement), and the device bay unit a is released. a can be taken out in the direction of arrow e.

In the above embodiment, the device bay unit a is detached by pushing the eject bar j by hand, but as shown in FIG.
The eject bar j is operated using a rack and pinion mechanism by a gear z attached to a shaft of the electric motor y,
Thereby, the device bay unit a can be removed from the personal computer main body.

[0022]

As described above, according to the first and second aspects of the present invention, the operation of releasing the movable claw (engaging portion) from the groove (engaged portion) on the side surface of the device bay unit, Since the eject operation for moving the unit in the removal direction is linked, the device bay unit can be easily removed by one operation, and the operation is not troublesome.

According to the third and fourth aspects of the present invention, it is possible to realize a structure for easily taking out the device bay unit at low cost. In addition, it is possible to provide a time difference between the operation of removing the movable claw from the groove on the side surface of the device unit and the operation of pushing out the device bay unit from the back surface to remove the device bay unit, and the operation of removing the movable claw from the groove on the side surface of the device bay unit. Can be performed independently. This makes it possible to reliably prevent the device bay unit from falling off.
