PURPOSE: To output a signal by automatically switching a relative coordinate and an absolute coordinate corresponding to a contact area. CONSTITUTION: At the time of operating a tablet 51 by means of a finger and a pen, a detection circuit 61 detects the contact areas. Then, when the contact area is larger than a prescribed value, a signal corresponding to the relative coordinate of a point P at which the finger or the pen is brought into contact with the tablet 51 is outputted but when the contact area is not larger than the prescribed value, a signal corresponding to the absolute coordinate is outputted to be supplied for a transmission module 65. The signal supplied for the transmission module 65 is FM-modulated and then transmitted through a transmission antenna 66. Keys 52 and 53 are used at the time of click operation. When a power supply switch 64 is operated, power supply voltage from a battery 63 is supplied for a circuit through a power supply circuit 62. |
