Power saving device for cordless electronic device such as optical mouse, has motion switch which reactivates electronic device that has assumed standby state after predetermined time

摘要

The device includes a motion switch (23) arranged on a circuit board in the electronic device, and connected to the input of a microprocessor (25), as well as to the circuit board power supply Vcc. After a predetermined time without activity, the electronic device assumes a standby state and is deactivated. After the motion switch closes, the electronic device returns to operating state by resuming supply of power to the microprocessor and the remaining components on the circuit board. An independent claim is included for a further power saving device.
