Abstract

Reduces energy consumption by running hands only when needed. By pressing down the mode changeover switch, the second hand can be selectively moved to the position of the pointer running start time setting mode (wake-up), the position of the pointer running stop time setting mode (sleep) and the position of the alarm time setting mode (alarm) . With the second hand at each setting mode position, set the hour / minute hand to the desired time by pressing the time setting switch, thereby setting the hand stop time, hand start time, and alarm time. When the pointer operation stop time is reached, the operation of the pointer is stopped, and when the pointer operation start time is reached, the time pointer is rapidly advanced to the normal time, and then the normal time display is performed. In the case that the pointer operation stops, within a predetermined period of time before the alarm time is reached, the pointer operates in a manner similar to the above, returning to a normal operating state, and then an alarm is generated when the alarm time is reached.

Description

technical field

[0001] The present invention relates to an electronic timepiece that can drive a time hand to rotate based on the rotation of a motor. Background technique

[0002] Traditionally, electronic timepieces are used to display the time, which is realized by the rotation of time hands such as the hour hand driven by a motor. The electric motor is powered by a battery, so the less energy the motor consumes, the better.

[0003] Conventionally, an electronic timepiece using a primary battery is designed to operate the electronic timepiece with a battery having a capacity to satisfy a predetermined service life based on current, and therefore, does not provide a power saving function to reduce power consumption.

[0004] Meanwhile, in the electronic timepiece described in Japanese Laid-Open Patent Publication No. 304555 / 1997 or Japanese Laid-Open Patent Publication No. 319143 / 1998, according to an energy generating timepiece using a storage battery charged by an ener...
