| 20090184884 | PORTABLE TERMINAL APPARATUS WITH TV FUNCTION AND TV ANTENNA WITH FUNCTION AS INPUT PEN - 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. | 07-23-2009 |
