Abstract: A mobile terminal apparatus includes upper and lower cases; a sliding-rotation-mechanism performing an opening-direction-sliding-movement through a sliding-supporting plate at opening manipulation, allowing the upper case to stand up at a predetermined angle with respect to the lower case after the opening-direction-sliding-movement, performing closing-direction-rotation-movement, standing up at the predetermined angle through the sliding-supporting plate at closing manipulation, and performing closing-direction-sliding-movement through the sliding-supporting plate after the closing-direction-rotation-movement; and a flexible board disposed so that electrical parts of the upper and lower cases are electrically connected to each other and a portion corresponding to a predetermined length just after the portion exposed from the upper case is adhered to the sliding-supporting plate through an adhesive.

Abstract: A slide rotation device includes a rail portion that is provided along a sliding direction of an upper case, a slide mechanism that has a slide assistance plate sliding the upper case along the rail portion of the upper case, and a rotation mechanism that is provided to be fixed in the vicinity of one end portion of a lower case and rotatably supports the slide assistance plate using a rotation shaft positioned in an extending direction of the slide assistance plate.

Abstract: Provided is a mobile terminal apparatus including: upper and lower cases; a sliding-rotation-mechanism fixed to the upper case, performing an opening-direction-sliding-movement on the upper case through a sliding-supporting plate at opening manipulation, allowing the upper case to stand up at a predetermined angle with respect to the lower case by performing an opening-direction-rotation-movement through the sliding-supporting plate after the opening-direction-sliding-movement, performing closing-direction-rotation-movement opposite to the opening-direction-rotation-movement, standing up at the predetermined angle through the sliding-supporting plate at closing manipulation, and performing closing-direction-sliding-movement opposite to the opening-direction-sliding-movement through the sliding-supporting plate after the closing-direction-rotation-movement; and a flexible board which is disposed between the upper and lower cases so that electrical parts of the upper and lower cases are electrically connected t
