Abstract:
A diaphragm (10) is fixed to a bottom board (102) by a screw (13). A lever (20) is formed with a spring section (23), a rotor attaching section (25), and an insertion hole (22), the insertion hole (22) having a shaft (21) inserted therein to turnably support the lever (20) on the shaft. The spring section (23) is abutted against an eccentric pressure-adjusting cam (26), the latter being turned to change the elastic force of the spring section (23) so as to adjust the pressing force actuating the diaphragm (10) through a rotor (100).
Abstract:
An electronic timepiece provided with a month-end non-correction device for a simple calendar in which date can be read positively in a short time. A date detection pattern (71) consisting of a reflection part and a non-reflection part is formed on the rear surface of a date plate (70), a transition across the boundary is read by a photosensor (81) when the date plate (70) rotates and the number of days required by a control circuit (20) is decided by a permanent calendar circuit to drive a date plate drive mechanism (51, 52).
Abstract:
The electronic clock movement comprises an analog display device with a date ring (6) and a stop watch hand (4) associated with a graduation (5) of a usual small counter. This ring and this hand are driven by one and the same electric motor (10) via a set of permanent gears, the stop watch hand being mounted on a wheel of this set of permanent gears which wheel is arranged between the driving pinion (14) and a runner comprising a date drive wheel (24). The date ring and the date drive wheel respectively comprise two tooth sets forming a permanent mesh with a relatively large amount of lash making it possible to define a determined angular dead zone for the date drive wheel because the date ring is positioned by a jumper. This angular dead zone is used to drive the stop watch hand independently of the date ring. The set of permanent gears is arranged in such a way that the torque for positioning the rotor gives rise, at the date drive wheel, to enough of a blocking torque to perform a shock-proof function.
Abstract:
A date display assembly (100) for displaying the day of the month in an electronic device. The assembly comprises a units ring (105) and a tens disc (120), the units ring comprising at least one series of numerals from 0 to 9 and the tens disc comprising a series of numerals from at least 1 to 3 and optionally the numeral 0. The units ring and the tens disc are positioned relative to each other so as to display in the space of a window (122) two numerals side by side, one of which is carried by the units ring (105) and the other of which is carried by the tens disc (120). The units ring is divided into ten sectors or a multiple of ten sectors each separating the numerals 0 to 9, the one sector separating the numerals 9 - 0 having an angular extent equal to 3/4 of the angular extent of the sectors separating the other numerals. In the preferred embodiment, the device is a timepiece and a wristwatch in particular.
Abstract:
A date display assembly for an electronic device, the assembly comprising a ones date ring assembly (21), a tens date disc assembly (6) and a gear assembly (7B) comprising a four-legged blocking star (12) and a four-legged driving star (11). The driving star (11) is used for driving the tens disc (6) and the blocking star (12) is used to maintain the proper orientation of the tens disc.
Abstract:
A timepiece comprising a date display, comprising a date display assembly comprising a date ring, a first gearing assembly being meshingly coupled to the date ring for causing the rotation of the date ring; and a stepping motor comprising a rotor, wherein the rotor of the stepping motor is rotateable coupled to the at least one or more wheels of the first gearing assembly, wherein the rotation of the rotor causes the date ring to rotate; a date-keeping assembly operatively coupled to the date display assembly, comprising: at least a second gearing assembly comprising at least an hour wheel and a detection wheel assembly, wherein at least certain rotational increments of the detection wheel, and the clockwise or counterclockwise direction thereof, causes the rotor of the stepping motor to rotate so that the date ring can be rotated in one of a clockwise or counterclockwise direction; whereby the rotation of the hour wheel through a predetermined midnight position results in that the stepping motor causes the date ring to rotate a predetermined number of degrees, thereby advancing either in the forward or backward direction a displayed digit on the date ring representing a valid date. Methodologies for setting and adjustment are also provided.
Abstract:
An electronic timepiece comprising a calendar feed device that allows a date correction in a short time and is resistant to an external impact, a date plate feeding convertor (51) that is started by a 24-hr switch (12) generating a date plate drive signal every 24 hours, and a Geneva wheel used in a date feed mechanism (date train wheel) (52) and stabilizing a date plate (70), wherein an eccentric cam provided coaxially with the Geneva wheel controls a bounding lever.
Abstract:
An electronic apparatus comprising function driving means (59 and 60) which generate function driving signals corresponding to a plurality of functions, a plurality of function display means (1 and 10) which are so provided as to correspond to the functions, and a driving means (22) which transmits driving forces to the function display means (1 and 10) simultaneously in accordance with the function driving signals from the function driving means (59 and 60). The function display means comprises a time lapse display means (10) whose display state is successively changed according to the driving force from the driving means (22) and a calendar display means (1) whose display state is intermittently changed according to the driving force from the driving means (22).
