Problems solved by technology

[0008] However, in the case of rollers utilizing active elements, since the rotation of the rollers is detected by supplying power to the elements, power is supplied to each active element even in the standby mode in which the rollers are not working, which causes a disadvantage of wasting power

Abstract

The object of the present invention is to provide an electronic device capable of reducing consumption of power supplied to active elements used for a rotary operation unit in a stand-by time. <??>The electronic device according to the present invention includes the rotary operation unit that is freely rotatable, active elements 31 and 32 for detecting rotation of the rotary operation unit, and control means 43 for controlling the power supply to the active elements 31 and 32 depending on a state of the device.

Description

technical field [0001] The present invention relates to electronic equipment suitable for application in mobile telephone units, PDAs (Personal Digital Assistants) or similar devices comprising rotary operating means. Background technique [0002] Conventionally, what is called a jog dial has been developed as a rotary operating device that can be incorporated into electronic equipment such as mobile phone units. The mechanism for detecting the rotation of the roller consists of a rotating disk and a fixed disk pressed almost parallel to it, forming a rotary encoder. In addition, for example, a group of counter electrodes arranged on a rotating disk is in slidable contact with several groups of counter electrodes arranged on a fixed disk, each electrode is slightly offset in the circumferential direction, and when the rotating disk rotates, A pulse signal having a phase difference depending on the direction of rotation is obtained in order to detect rotation (for example, r...
