Satellite radio-controlled wristwatch

摘要

In a satellite radio-controlled wristwatch, processing ranging from a user's operation through a reception operation to the completion of time adjustment is rapidly accomplished. The satellite radio-controlled wristwatch according to the present invention includes: a satellite radio wave reception unit including an antenna, a high frequency circuit, and a decoder circuit; an analog indication member for indicating at least that a reception operation is in process and a reception result; a clock circuit for holding and counting an internal time; an operating member for receiving an operation of a user; and a controller for controlling timings of at least: an activation operation of activating the satellite radio wave reception unit; an acquisition and tracking operation of acquiring and tracking a certain satellite radio wave; a time information acquisition operation of acquiring time information from the satellite radio wave; a continuous operation detection operation of detecting that the operating member is operated continuously; and a reception indication movement operation of moving the analog indication member to a position indicating that the reception operation is in progress, the controller being configured to carry out such control that the reception indication movement operation overlaps with at least one of the activation operation or the acquisition and tracking operation.

主权项

1. A satellite radio-controlled wristwatch, comprising:
a satellite radio wave reception unit comprising an antenna for receiving a satellite radio wave, a high frequency circuit, and a decoder circuit; an analog indication member for indicating at least that a reception operation is in process, and for indicating a reception result; a clock circuit for holding and counting an internal time; an operating member for receiving an operation of a user; and a controller for controlling timing of at least:
an activation operation of supplying power to the satellite radio wave reception unit for activation thereof;an acquisition and tracking operation of acquiring and tracking a certain satellite radio wave by the satellite radio wave reception unit;a time information acquisition operation of acquiring time information from the satellite radio wave received by the satellite radio wave reception unit;a detection operation which detects if the operating member is operated continuously for a predetermined operation reception time period; anda reception indication movement operation of moving the analog indication member to a position indicating that the reception operation is in progress, the controller being configured to carry out such control that the reception indication movement operation overlaps with the acquisition and tracking operation, wherein the controller starts the activation operation during the continuous operation detection operation after the detection operation is started.
