A new and efficient input device of an electrode contact type which has a high mechanical strength and durability and can assure accurate detection of coordinates. The input device comprises an elastic flexible insulator spacer having a conductive element embedded therein which may be a gauze of thin wires of a good conductive material knit into the form of a grid. Upon depression of an outermost insulator protective sheet, a portion of the spacer is deformed to expose the conductive element bel...

Input unit for electronic equipment, consisting of a body of insulating material with finger guides in which sensor contacts and pushbutton switches are arranged. By moving the finger along the guides characters can be written and the sensor contacts produce corresponding electrical signals. By operating a corresponding pushbutton it is indicated that the writing-in operation is completed.

An input device for use in a display unit serving as a terminal of a computer has first and second insulating sheets and an insulating spacer sandwiched between the first and second sheets. The first sheet has first terminal leads on its both ends, while the second sheet has second terminal leads which extend in perpendicular relation to the first terminal leads. The upper surface is covered with a flexible, insulating, protective sheet. The spacer includes lattice-like conductors and consists o...

An input buffer circuit for translating TTL level inputs to CMOS levels and which constitutes a part of a monolithic semiconductor device is provided. An input inverter stage has the source of its load transistor connected via a bipolar transistor to a first voltage level. When a second voltage level at which the monolithic semiconductor device is intended to operate exceeds the first voltage level, an MOS transistor coupled in parallel with the bipolar transistor bypasses the bipolar transistor...

A display panel disposed on the front surface of a device shows information related to an operation input. A sensor for detecting a touch of an object is disposed on the back surface of the device. A mark representing the touch position is displayed at a position directly above the position of a touch detected by the sensor on the display panel. When the mark representing the touch position and the display position of the information are overlapped, an input process corresponding to the overlapp...
