The protrusion 38A of the slide portion 38 is inserted into the guide portion 40 (groove). The guide portion 40 guides the protrusion 38A of the slide portion 38 that moves in conjunction with the movement of the support portion 34 in the insertion direction or the extraction direction.

The guide portion 40 has a first guide groove 52 that guides the protrusion 38A of the slide portion 38 in the insertion direction, and a second guide groove 54 that guides the protrusion 38A in the extraction direction. The guide portion 40 branches into a first guide groove 52 and a second guide groove 54 at a portion spaced apart from the end 50 on the extraction direction side in the insertion direction. The first guide groove 52 extends from a branching portion 55 between the first guide groove 52 and the second guide groove 54 in a direction crossing the insertion direction, bends in the insertion direction, and extends along the insertion direction to the end.

The groove bottom of the branch portion 55 between the first guide groove 52 and the second guide groove 54 is lower than the groove bottom of the second guide groove 54 and is approximately the same as the groove bottom of the first guide groove 52 . The groove bottom of the branch portion 62 between the first guide groove 52 and each first branch groove 58 is lower than the groove bottom of the first guide groove 52 on the extraction direction side from the branch portion 62. It is approximately the same as the groove bottom of the first guide groove 52 on the insertion direction side. The groove bottom of the first branch groove 58 is inclined to become higher as it goes from the branch part 62 to the locking groove 56, and the groove bottom of the second branch groove 60 is sloped higher as it goes from the lock groove 56 to the branch part 64. It is slanted so that The groove bottom of the locking groove 56 is lower than the groove bottom of the end of the first branch groove 58 on the locking groove 56 side.

Next, the operation of the holding unit 24 will be explained. In the holding unit 24, when the USB memory 18 is not inserted, the support part 34 is located at the end on the insertion opening 20 side inside the cylindrical frame 26, and the slide part 38 is fixed to the support part 34. The protrusion 38A at the tip is located at the end 50 of the guide portion 40 (groove) in the extraction direction. Note that when the support portion 34 is located at the end on the insertion port 20 side inside the cylindrical frame 26, the support portion 34 does not need to be urged by the urging portion 36.

When the connector section 18A of the USB memory 18 inserted from the insertion port 20 is connected to the device side connector section 30 attached to the support section 34, the USB memory 18 and the main board 42 are connected via the flexible board 32. (See Figure 4).

In this state, the USB memory 18 is inserted into the cylindrical frame 26 by the operator pressing the USB memory 18 with a pressing force greater than the urging force of the urging section 36 . When the USB memory 18 is inserted, the support part 34 moves inside the frame 26 in the insertion direction in response to the insertion, and the protrusion 38A of the slide part 38 that is linked to the movement of the support part 34 moves on the guide part 40. It is guided along the first guide groove 52.

Note that the groove bottom of the branch portion 55 (see FIG. 5) is lower than the groove bottom of the second guide groove 54 and approximately the same as the groove bottom of the first guide groove 52. Therefore, the protrusion 38A is guided from the branch portion 55 to the first guide groove 52 in response to insertion of the USB memory 18.

Further, the groove bottom of each of the plurality of branch parts 62 (see FIG. 5) is approximately the same as the groove bottom of the first guide groove 52 on the insertion direction side from the branch part 62, and The groove bottom of the groove 58 is inclined to become higher from the branch portion 62 toward the locking groove 56. Therefore, the protrusion 38A is guided from the branch portion 62 to the first guide groove 52 in response to insertion of the USB memory 18.

After the entire USB memory 18 is inserted into the cylindrical frame 26, the operator releases the USB memory 18, thereby releasing the USB memory 18. When the USB memory 18 is released from insertion, the support part 34 moves in the ejection direction due to the urging force of the urging part 36, and the protrusion 38A of the slide part 38, which is interlocked with the movement of the support part 34, moves in the ejection direction. It is guided from the nearest branch portion 62 to the locking groove 56 through the first branch groove 58 .

Note that the groove bottom of the branching portion 62 (see FIG. 5) is lower than the groove bottom of the first guide groove 52 on the extraction direction side from the branching portion 62, and is lower than the groove bottom of the first branching groove 58 from the branching portion 62. is inclined to become higher from the branch portion 62 toward the locking groove 56. Therefore, the protrusion 38A is guided from the branch portion 62 to the locking groove 56 through the first branch groove 58.

The bottom of the second branch groove 60 from the locking groove 56 (see FIG. 5) is inclined to become higher from the locking groove 56 toward the branch portion 64. Therefore, the protrusion 38A guided by the locking groove 56 remains in the locking groove 56 and is locked in the locking groove 56 by the urging force of the urging section 36.

In this embodiment, the projection 38A of the slide portion 38 is pulled out of the first guide groove 52 by the urging force of the urging portion 36 when the USB memory 18 inserted from the insertion port 20 is released. It is guided and locked in the locking groove 56 closest to the exit direction.

Therefore, as shown in FIG. 6, for example, by locking the slide portion 38 in the second locking groove 56 in the insertion direction from the insertion port 20, the length in the insertion/extraction direction is the first length. Memory 18 can be housed within housing 12. For example, as shown in FIG. 7, by locking the slide portion 38 in the first locking groove 56 in the insertion direction from the insertion port 20, the length in the insertion/extraction direction is shorter than the first length. A second length of USB memory 18 can be accommodated within the housing 12.

When removing the USB memory 18, the operator presses the USB memory 18 and then releases the press. The groove bottom of the locking groove 56 (see FIG. 5) is lower than the groove bottom of the end of the first branch groove 58 on the locking groove 56 side. Therefore, when the USB memory 18 is pressed, the protrusion 58A is released from the locking groove 56 and is guided to the second guide groove 54 through the second branch groove 60. Thereafter, when the pressure on the USB memory 18 is released, the urging section 36 urges the support section 34 so that the support section 34 returns to the end on the insertion port 20 side inside the cylindrical frame 26. The protrusion 38A of the slide portion 38, which is interlocked with the movement of the support portion 34, returns to the end portion 50 of the guide portion 40.

As described above, in this embodiment, the protrusion 38A of the slide portion 38 is released from the locking groove 56 and guided to the second guide groove 54 in response to pressure in the insertion direction with respect to the USB memory 18. Thereby, even if the length of the USB memory 18 in the insertion/extraction direction is different, the USB memory 18 can be extracted.
