Utilize said structure, when the operating portion 141 of surface direction (being left direction in Figure 13 in this example) sliding manipulation part 140 along shutter door 4, tapered portion 142 is similarly mobile along surface direction (being right direction in Figure 15 in this example) in the inner side of shutter door 4.Thus, slide between the taper surface 142a of tapered portion 142 and hold assembly 110,2 hold assemblies 110 move in the direction away from each other.When operator stops slide and makes finger leave from operating portion 141, functional unit 140 returns initial position B by the active force of spring 104, hold assembly 110 returns initial position P by the active force of spring 102, or, the housing section 52 of the USB storage 50 being installed on socket 3 is kept.Like this, functional unit 140 plays function as the slide switch that can be expanded hold assembly 110 by slide.In addition, the initial position P of this variation refers to the position of the hold assembly 110 under the state do not operated functional unit 140 shown in Figure 14 and Figure 15.

Next, with reference to Figure 16, method of operation during handling USB storage 50 is described.

When installing USB storage 50, as shown in Figure 16 (a), operator opens shutter door 4, such as, utilize thumb and forefinger to pinch the operating portion 141 of operating portion 140, and this operating portion 141 is slided to the direction shown in hollow arrow.Thus, tapered portion 142 side direction equidirectional in shutter door 4 moves, and slides between the taper surface 142a of tapered portion 142 and hold assembly 110, thus 2 hold assemblies 110 overcome spring 102 active force and away from.Its result is, the interval in plate portion 111,111 is opened, and therefore, operator inserts the connecting portion 51 of USB storage 50 to socket 3, thus USB storage 50 is installed to control device 1.

Then, when operator stops slide and makes finger leave from operating portion 141, as shown in Figure 16 (b), functional unit 140 returns initial position B by the active force of spring 104.Further, hold assembly 110 moves to direction close to each other by the active force of spring 102, and the elastomeric element 112 being arranged at plate portion 111 is clamped the housing section 52 of the USB storage 50 being installed on socket 3 from upper and lower both sides and keeps it.Like this, the installation of USB storage 50, and keep the state after installing with high confining force.

According to variation described above, except obtaining the effect identical with above-mentioned execution mode, following effect can also be obtained.That is, due to the slide switch that functional unit 140 is the surface direction movement along shutter door 4, compared with the situation being therefore button or tension-torsion with functional unit, the stroke of functional unit 140 (tapered portion 142) can be increased.Thus, compared with the situation being button or tension-torsion with functional unit, the inclination (inclination relative to moving direction) of tapered portion 142 can be reduced, therefore, it is possible to reduce the power required for operation of operating portion 141.Its result is, can improve the operability of functional unit 140.

In addition, the slide direction of operating portion 141 also can be made to be direction (rightabout of Figure 16 (a) hollow core arrow) contrary to the above.In this case, as long as the configuration making the conical part 142 shown in Figure 15, spring 104 and protuberance 44 relative to hold assembly about 110 on the contrary.
