发明名称 ANALOG ELECTRONIC TIMEPIECE WITH POSTURE SENSOR
摘要 <p>An analog electronic timepiece of the invention includes a plurality of motors, a plurality of display members operated by rotation of the plurality of motors for displaying time information, an attitude sensor 610 for detecting an attitude of the analog electronic timepiece, an attitude detecting portion 340 for detecting the attitude of the analog electronic timepiece based on an output signal of the attitude sensor 610 and an output determining portion 344 for outputting a signal for controlling operation of the rotation of the plurality of motors based on an output signal of the attitude detecting portion 340. When the attitude detecting portion 340 determines that the analog electronic timepiece is brought into a previously determined attitude, based on the output signal of the attitude detecting portion 340, all of themotors are stopped. The output determining portion 344 is constituted to measure a difference between current time and time at which an hour hand, a minute hand and a second hand are stopped. When the attitude detecting portion 340 determines that the analog electronic timepiece is not brought into the previously determined attitude, based on the output signal of the attitude detecting portion 340, the hour motor 210 is driven to accelerate to reach a position at which the hour hand indicates the current time, the minute motor 240 is driven to accelerate to reach a position at which the minute hand indicates the current time and the second motor 270 is driven to accelerate to reach a position at which the second hand indicates the current time. &lt;IMAGE&gt;</p>
