Document Type and Number:
Japanese Patent JPH0824272
Kind Code:
B2
Abstract:
PURPOSE:To reduce the power consumption by making on/off a receiving means periodically while waiting transmission signals. CONSTITUTION:The first power source circuit 26a makes an intermittent operation that turns on for T1 (for instance 0.05sec) and turns off for T2 (for instance 0.25sec), and judges whether there is a received signal or not during time T1 (time of power source on). When there is no receiving signal, the intermittent operation is continued, and when there is receiving signal, a code is read after continuing ON of the first power source circuit 26a. In the case where the reading of the code is completed, or the code is not sent in within a fixed time, the first power source circuit 26a is turned off.
