## Abstract

A tactile sensation providing apparatus, so as to reduce an influence by provision of a tactile sensation on detection of a position by a touch sensor, includes a touch sensor 11, a tactile sensation providing unit 12 disposed near the sensor 11 and configured to vibrate the sensor 11, a touch sensor control unit 20 configured to transmit a scanning signal to the sensor 11 and, by receiving the signal from the sensor 11, to detect the position of the contact to the sensor, signal lines 16, 18 configured to transmit the signal between the sensor 11 and the control unit 20, and a tactile sensation control unit 30 configured to, based on the position of the contact detected by the control unit 20, control the providing unit 12 to vibrate the sensor 11. The providing unit 12 is disposed avoiding overlapping with the lines 16, 18.

## Claims

### Claim 1

A tactile sensation providing apparatus comprising:
a touch sensor;
a tactile sensation providing unit disposed near the touch sensor and configured to vibrate the touch sensor;
a touch sensor control unit configured to transmit a scanning signal to the touch sensor and, by receiving the scanning signal from the touch sensor, to detect a position of a contact to the touch sensor;
a signal line configured to transmit the scanning signal between the touch sensor and the touch sensor control unit; and
a tactile sensation control unit configured to, based on the position of the contact detected by the touch sensor control unit, control the tactile sensation providing unit to vibrate the touch sensor, wherein
the tactile sensation providing unit is arranged avoiding overlapping with the signal line.

### Claim 2 (depends on 1)

The tactile sensation providing apparatus according to claim 1, wherein the touch sensor includes a capacitive type touch sensor.

### Claim 3

A tactile sensation providing apparatus comprising:
a touch sensor;
a tactile sensation providing unit configured to vibrate the touch sensor; and
a tactile sensation control unit configured to control such that a period in which scanning is performed for detecting a position of a contact to the touch sensor and a period in which the tactile sensation providing unit vibrates the touch sensor do not overlap with each other.

### Claim 4 (depends on 3)

The tactile sensation providing apparatus according to claim 3, wherein the touch sensor includes a capacitive type touch sensor.

### Claim 5 (depends on 3)

The tactile sensation providing apparatus according to claim 3, wherein the tactile sensation control unit, during the period in which the touch senor is vibrated, applies a drive voltage such that the tactile sensation providing unit generates vibration.
