ABSTRACT:
An electronic pen has a body frame in a rod-like or pillar-like shape with an input mechanism and an output mechanism respectively on each end. A slope detecting mechanism changes a circuit system corresponding to the slant state of the body frame of the electronic pen, so that power is supplied from a battery to only either an input mechanism control circuit or an output mechanism control circuit. Consequently, power is supplied only to a circuit system in use. Thereby, unnecessary power consumption is prevented, and the device can be used for a long time.
