摘要:
A calendar timepiece has a main plate, a time indicator mounted on the main plate for undergoing rotational movement to indicate time information, a date indicator mounted for undergoing rotation to indicate date information, and a date indicator driving wheel mounted on the main plate for undergoing rotation. A date jumper is disposed on the main plate and has a train wheel comprised of a date indicator setting portion for controlling rotation of the date indicator by engagement with the inner teeth portion of the date indicator. The date indicator setting portion has a first setting portion for contacting a tip of a first tooth of the date indicator, a second setting portion, and a third setting portion for contacting a tip of a second tooth of the date indicator. Each of the first, second, and third setting portions has a generally linear surface portion disposed at an angle relative to one another.

An electronic timepiece with date display function reduces power consumption in conjunction with the user adjusting the date, and makes it easier for the user to set the date. A displayed date detection unit H has a day detector H1 for detecting the displayed day, a month detector H2 for detecting the displayed month, and a year detector H3 for detecting the displayed year. A control unit A controls a calendar mechanism drive unit F according to the date detected by detectors H1 to H3.

A timepiece comprises a standard time clock for counting standard time and means for calculating daylight saving time by adding a predetermined time correction value to the standard time when judging that the standard time is within the period of daylight saving time. When a time input for setting the timepiece is after a daylight saving time starting time as expressed in the standard time and before a daylight saving time starting time as expressed in daylight saving time, the timepiece corrects the input time by adding the time correction value thereto and sets the corrected time as daylight saving time for the standard time clock.A monitoring camera device comprises the timepiece. Time data output from the timepiece when an image is captured is added as image capturing time data to image data obtained by capturing the image.

To provide a winding stem structure, which can remove and disassemble two inner and outer winding stem portions, if any, and a watch provided with the winding stem structure. A winding stem structure of a watch comprises a first winding stem including a first gear and a first radially small portion; a second winding stem including a second gear to mesh with the first gear and a second radially small portion, and a joint ring for jointing the first and second winding stems. The joint ring includes a plate-shaped lever member having a first recess opened at its one end for accepting the first radially small portion of the first winding stem removably, and a second recess opened at its one end for accepting the second radially small portion of the second winding stem removably, and a return spring mounted removably and elastically on the plate-shaped lever member while covering the recesses of the first and second recesses of the plate-shaped lever member in the state where the first and second recesses of the plate-shaped lever member accept the first and second winding stems.

摘要:
A rectangular vibrating plate 10 in which a piezoelectric element and a reinforcing plate are stacked is supported on a main plate by a support member 11, and is urged toward the rotor 100 by an elastic force of the support member 11. This brings a projection 36 provided on the vibrating plate 10 into abutment with an outer peripheral surface of the rotor 100. In this construction, when the vibrating plate 10 vibrates in the horizontal direction in the figure by an applied voltage from a driving circuit (not shown), the rotor 100 is rotated in a clockwise direction in accordance with the displacement of the projection 36 due to the vibration.
