For example, the second accommodating part 332 includes a fixing part 332a and a cover part 332b which is coupled to the fixing part 332a to cover the second memory card 12. The cover part 332b may be rotatably coupled to the fixing part 332a so that the fixing part 332a may be opened. Therefore, the memory card 12 may be removed from the fixing part 332a by opening the cover part 332b. In addition, the second storage unit 332 may be replaced with another memory card.

The cover part 332b includes an opening 332c. The opening 332c is formed to expose a contact portion of the second memory card 12 in electrical contact with the connector 400.

The first and third accommodating parts 331 and 333 also include a fixing part, a cover part, and an opening part, and the shape and function thereof are substantially the same as the second accommodating part 332, and thus redundant description thereof will be omitted.

However, the shapes of the first to third accommodating parts 331, 332, and 333 are not limited thereto. For example, the first to third memory cards 11, 12, and 13 may be formed in a pack shape in which one region is opened so as to be accommodated by sliding.

The protrusion 10 is formed on the second rotating member 320. The protrusion 10 is spaced apart from the rotation shaft 301 by a distance substantially equal to a distance from which the first to third accommodating parts 331, 332, and 333 are spaced apart from the rotation shaft 301. It is formed to be symmetrical. That is, the protrusion 10 is formed to have substantially the same shape as the first to third accommodating parts 331, 332, and 333.

The protrusion 10 may contact the connector 400 by the rotation of the second rotating member 320. That is, when the user does not want to contact all of the first to third memory cards 11, 12, and 13 with the connector 400, the protrusion 10 may be connected to the second rotating member 320. Rotate in contact with 400). As a result, it is possible to prevent shaking due to an external pressure of the second rotating member 320 installed in the first rotating member 310 by the rotating shaft, thereby making it possible to secure the internal structure.

Referring to FIG. 6, the connector part 400 is formed to face the second rotating member 320 of the terminal body. The connector part 400 includes a connector body 400, a contact protrusion 420, and first and second guide parts 431 and 432.

The connector body 410 is formed to protrude from the terminal body to a predetermined height, and the contact protrusion 420 is formed on the connector body 410. The contact protrusion 420 may be in electrical contact with one of the contacts of the first to third memories 11, 12, and 13 to transmit and receive information. The contact protrusion 420 and the contact portion may be formed to be parallel to the tangent of the radius of rotation of the first and second rotating members 310 and 320. For example, the connector body 410 may be formed in a quadrangular shape including first to fourth surfaces. The connector body 410 may include a first surface adjacent to the rotation shaft 301, a second surface facing the first surface, a third surface connecting the first and second surfaces and facing each other, and the fourth surface. It may include cotton. The contact protrusion 420 may be arranged to be adjacent to a second surface parallel to the tangent line. In addition, the contact protrusion 420 may be formed to protrude from the connector body 410.

Therefore, since the contact parts are stably contacted with the contact protrusion 420, and the contact protrusion 420 is pressed while being coupled to the inside, damage due to rotation can be minimized.

The first and second guide parts 431 and 432 are formed adjacent to the third and fourth surfaces, respectively. The first and second guide parts 431 and 432 guide the movement of the first to third memory cards 11, 12 and 13 and the protrusion 10. That is, the first to third memory cards 11, 12, and 13 pass through the first guide part 431 by the rotation of the first and second rotating members 310 and 320, and thus the connector body 410. After overlapping with the second guide portion 432 passes.

One end of each of the first and second guide parts 431 and 432 has a first height that is substantially the same as the height of the connector body 410, and the other end of the first and second guide parts 431 and 432 is formed. It is formed to a second height lower than the height. The second height is formed to be lower than a distance between one of the first to third memory cards 11, 12, and 13 that do not overlap the connector unit 400, and the terminal body.

For example, surfaces of the first and second guide parts 431 and 432 may be formed in a curved surface. Therefore, the connector body 420 may protrude without overlapping the protruding connector body 420. Therefore, the rotation of the first and second rotating members 310 and 320 can be freed and damage to the memory card and the connector 400 can be prevented.

Hereinafter, the method of contacting and releasing the memory card with the connector unit 400 by the operation of the first and second rotating members 310 and 320 and the rotating shaft 301 will be described.

7A is a cross-sectional view of the memory card and the connector separated from each other. 7B is a cross-sectional view of a state where the memory card and the connector are in contact with each other.

Referring to FIG. 7A, the rotating shaft 301 is formed to protrude from the second rotating member 320 toward the first rotating member 310, and has a space formed to accommodate the elastic member 301b therein. It includes an outer wall 301a. One end of the outer wall 301a may be provided with a hook portion so that the second rotating member 320 is not separated from the first rotating member 310.

The elastic member 302b elastically supports the second rotating member 320 from the first rotating member 310, and the first rotating member 310 and the second rotating member 320 due to the hook portion. Should not be separated.

 The first memory card 11 and the protrusion 10 do not overlap the connector 400. In this case, the second rotating member 320 is the elastic member 301b disposed inside the central shaft 301 to elastically support the second rotating member 320, the elastic member 301b is the maximum Expanded to However, since the second rotating member 320 overlaps the connector portion 400 and the hook portion is coupled to the first rotating member 310, the second rotating member 320 is the first rotating member 320. It is not separated from the rotating member 310.

When the first and second rotating members 310 and 320 rotate, the first memory card 11 and the protrusion 10 rotate in one direction. The first memory card 11 moves along the first guide part 431 by rotation. The first guide part 431 includes a shape that is higher in the connector body 410 toward the connector body 410, and has a curved surface. Therefore, as the first memory card 11 moves in contact with the first guide part 431 to the connector main body 410, the elastic member 301b of the rotation shaft 301 is compressed to form the first and the first parts. The gap between the two rotating members 310 and 320 is narrowed.

The first memory card 11 passes through the first guide part 431 to be in contact with the connector body 410. Accordingly, the contact protrusion 420 is pressed by the contact portion to make electrical contact.

When the second rotating member 320 rotates, the first memory card 11 moves to be spaced apart from the connector body 410 along the second guide part 432.

Since the elastic member 301a elastically supports the second rotating member 320, the contact portion and the contact protrusion 420 may be stably connected. In addition, the first guide part 431 may be formed to contact the connector body 410 on which the first memory card 11 protrudes. The first memory card 11 may be moved away from the connector body 410 without impact by the second guide part 432.

Therefore, the contact can be stabilized and the internal impact can be minimized to improve durability.
