IPC: G04G5/04
Filed: 1975-03-06
Abstract: 1474002 Electronic watches DAINI SEIKOSHA KK 21 Feb 1975 [7 March 1974] 7441/75 Heading G3T [Also in Division H1] In an electronic timepiece having a display (1), Fig. 1 (not shown) with several portions e.g. for the date, day, hours, minutes and seconds, a stem 17 is mounted on a base-plate 15 for axial and rotary movement and controls at least three switches to correct the display. Inner and outer positions of the stem are defined by a flange 27b of a spring 27 engaging the stem on respective sides of collar 17b. Square portion 17a of the stem carries a switch member 22, and a spring 24 biases this member and thus the stem to a central position in rotation. With the stem in its inner position as shown, all the switches are open and the watch runs normally. When the stem is pulled out, its end 17d allows a contact spring 18 to touch a contact pin 19, these parts forming an enabling switch 13 so that, by logic circuitry Fig. 2 (not shown), further switches 10-12 are rendered effective. The switch 10 is a function selector switch formed by a contact 25 and a lug 22a on member 22, so that if the stem 17 is now rotated clockwise this switch is closed and switch 11, which is a correcting switch, is connected via the logic to the date display (2) which becomes illuminated to show that it is available for correction. The switch 11 is formed by a second contact 26 and lug 22b and rotation of the stem anti-clockwise thus causes 1Hz pulses to pass to the date display. Subsequent clockwise rotations of the stem connect the switch 11 successively to the day, hours and minutes display portions (3-5), the selected portion being illuminated. Depression of the stem, while still in its outer position, against a spring 23 and contact spring 18, will cause the latter to touch a contact 20, thus closing switch 12 and setting the seconds counter (204) and display (6) to zero. The display is of liquid crystal type, illuminated by a lamp (9) when a switch 14 is closed. This switch is formed by the spring 18 and a further fixed contact 21 and is closed by depressing the stem in its inner position. The switch 12 is also thus closed but is ineffective since switch 13 is open.
