Abstract: Provided is a heat dissipation mechanism that allows for a smaller device while also facilitating disassembly. The heat dissipation mechanism is provided with a heat dissipation element, which releases heat externally. The heat dissipation element and a heating element that generates heat are in thermal contact with each other via a thermal conduction film formed from a thermally conductive material having the ability to flow, and via a low-friction film having a lower friction coefficient than the heat dissipation element or the heating element.

Abstract: Provided is an input device which has excellent operability by not requiring a finger to be released from a key during operation requiring the finger to shift and preventing the finger from touching a plurality of keys at the same time. A key (12) surrounding a selection key (18) is arranged. On a board (41), four metal domes (14) are arranged at positions corresponding to the four positions, i.e., upper, lower, right and left positions, of the key (12). A touch sensor (13) is arranged on an upper layer above the metal dome (14). The touch sensor (13) is brought into contact with a touch sensor presser (53), and an electrical value (for instance, a resistance value) is changed corresponding to shift of the finger on the key (12). When the key (12) is strongly pressed down, the top of the metal dome (14) is pressed into the substrate (41) side and electricity is carried between contact points (14a, 14b).

Abstract: A portable terminal apparatus with TV function and a TV antenna with function as an input pen, in which the TV antenna is integrated with the input pen for the touch panel while ensuring sufficient sensitivity so that the internal space of the apparatus is effectively utilized, thus rendering the apparatus smaller and lighter. In the case of using a TV antenna with function as an input pen as an input pen, a mounting operation portion is pushed in a longitudinal direction with a fingertip for pushing it into the apparatus. Thereby, the hold state of the apparatus is released by a function of a latch switch, and the TV antenna with function as an input pen is pushed out to be pulled out of the apparatus. That is, the cellular phone has a configuration in which the TV antenna with function as an input pen cannot be pushed to be detached from the apparatus unless the user contracts a multistage antenna section and houses it completely in a pen body.
