Abstract
A input device is provided which includes a clock signal generator that generates a clock signal; a delay unit that has a capacitive sensor where an electrode is formed on a substrate; protective sheets each of which is formed of a dielectric and which are disposed on front and rear surfaces of the capacitive sensor; a logical product unit that transmits an output signal on the basis of a clock signal obtained from the clock signal generator and a delay signal obtained from the delay unit; and a controller that makes a predetermined program executed in accordance with an output signal obtained on the basis of the logical product unit.
Claims10
An input device comprising:
- a clock signal generator that generates a clock signal;
- a delay unit that has a capacitive sensor where an electrode is formed on a substrate;
- protective sheets each of which is formed of a dielectric and which are disposed on front and rear surfaces of the capacitive sensor;
- a logical product unit that transmits an output signal on the basis of the clock signal obtained from the clock signal generator and a delay signal obtained from the delay unit;
- and
- a controller that makes a predetermined program executed in accordance with an output signal obtained on the basis of the logical product unit.
An electronic apparatus comprising:
- a capacitive sensor in which a detection electrode is formed on a film substrate;
- a first insulating sheet that is disposed so as to cover a front surface of the capacitive sensor;
- a second insulating sheet that is disposed so as to cover a rear surface of the capacitive sensor and has a different thickness from a thickness of the first protective sheet;
- and
- an input device that is composed of a discrimination unit to discriminate between input operation on the first insulating sheet and input operation on the second insulating sheet,
- wherein the input device is built in a case, and
- a detection signal output from the capacitive sensor at the time of performing input operation on the first insulating sheet is different from a detection signal output from the capacitive sensor at the time of performing input operation on the second insulating sheet.
An input device comprising:
- a capacitive coordinate detecting sensor in which an X electrode is formed on a front surface of a film substrate and a Y electrode is formed on a rear surface of the film substrate;
- a first insulating sheet that is disposed so as to cover the X electrode side of the capacitive coordinate detecting sensor;
- a switch member that is provided at the Y electrode side of the film substrate and enters an on/off state through pressing operation of the first insulating sheet side;
- a second insulating sheet that is disposed so as to cover a rear surface of the switch member;
- and
- a discrimination unit that discriminates between input operation on the first insulating sheet and input operation on the second insulating sheet,
- wherein a detection signal output from the capacitive sensor at the time of performing input operation on the first insulating sheet is different from a detection signal output from the capacitive sensor at the time of performing input operation on the second insulating sheet.
