That is, the hinge 35c-1 is moved along the hinge rail 35c-2 by the rotation of the connector module 50. Here, the hinge rail 35c-2 is preferably formed in an arc shape.

That is, when the button 33a is pressed, the multimedia terminal SP protrudes slightly out of the holder 31 together with the contact plate 35a. At this time, the contact plate 35a is rotated about the illustrated rotation shaft 35a-1, and rotates the connector module 50 connected to the lower portion of the multimedia terminal SP to the rear. And, since the hinge 35c-1 moves along the hinge rail 35c-2, the connector module 50 is rotated about the rotation shaft 35a-1 while being connected to the multimedia terminal SP. The connector module 50 may be connected to the multimedia terminal SP by the flexibility of the flexible cable FC even when the connector module 50 is rotated.

On the other hand, referring to Figure 7, the pressing force transmission member (35b) is different from the rack gear (35b-4), pinion (35b-5), bolt shaft (35b-6), nut (35b-7) and It may be configured to include a guide (35b-8).

The rack gear 35b-4 is integrally formed with the pressing member 33 installed on one side of the holder 31. The rack gear 35b-4 is movably inserted into the guide ring 31b provided in the holder 31. In addition, the rack gear 35b-4 is provided with the above-mentioned stopper 31a and is not detached from the holder 31. And the pinion 35b-5 is rotatably installed in the upper center of the holder 31, and engages with the rack gear 35b-4.
