Abstract: The present invention provides a digitizer for a fingertip tactile-sense input device to which switches can be added without having to increase the number of wires.

Abstract: A small switch having a liquid crystal display includes an operation button; a liquid crystal display device having a liquid crystal panel for displaying information including characters and/or pictures on the operation button and a printed circuit board on which an IC chip, which serves as a driver circuit for the liquid crystal panel, is mounted, the liquid crystal display device being housed in the operation button; a switch body including a contact mechanism for opening and closing an electrical path by vertically moving the operation button; and backlight sources having different colors. The liquid crystal panel is an antiferroelectric liquid crystal panel. The backlight sources are sequentially turned on at high speed below the antiferroelectric liquid crystal panel, and liquid crystal screens having different display contents for every color are displayed in synchronization with the turning on of the backlight sources to achieve multicolor display.

Abstract: A display switch includes switch elements disposed on a display which is capable of electrically changing images displayed thereon. Above the switch elements are disposed a plurality of buttons formed of a transparent material and supported by a frame member. A depression is formed in each of at least two opposite side surfaces of each button, and the frame member has flange portions that engage with the depressions in order to limit movement of the buttons. Also, elastic members are disposed under the buttons in order to allow each button to move during operation while imparting a feel to a user and to automatically return the button to its original position.

Abstract: An electronic display device for use in a motor car wherein the contents of the display are determined by the respective positions of a manually operated switch and the ignition switch is disclosed. A control circuit detects the respective positions of the two switches and thereby determines the data to be displayed.

Abstract: A digital electronic timepiece comprises oscillator means for generating reference clock-pulse signals, a plurality of counter means of successive stages for successively counting the reference clock-pulse signals and respectively producing output signals for displaying numerals at respective digit positions for seconds, tens of seconds, minutes, tens of minutes, hours, and tens of hours, means for digitally displaying time in response to signals for output display of the counter means, and means for supplying a time correction reset signal to the counter means for producing as output signals for display at the digit positions respectively for seconds, tens of seconds, minutes, and tens of minutes. The time correction reset signal resets the counter means for seconds, tens of seconds, minutes, and tens of minutes so that the output signal thereof becomes a signal for "O" display.
