## Abstract

A tactile presentation device includes a housing, a detection part one end portion of which is rotatably attached to the housing by a supporting member and which is operable to detect an operation performed on an operation surface thereof, and a vibration part attached to the detection part so as to cause the detection part to rotationally vibrate around the supporting member when the detection part detects the operation.

## Claims

### Claim 1

A tactile presentation device, comprising:
a housing;
a detection part one end portion of which is rotatably attached to the housing by a supporting member and which is operable to detect an operation performed on an operation surface thereof; and
a vibration part attached to the detection part so as to cause the detection part to rotationally vibrate around the supporting member when the detection part detects the operation.

### Claim 2 (depends on 1)

The tactile presentation device according to claim 1, wherein the vibration part causes the detection part to vibrate in a direction substantially horizontal to the operation surface.

### Claim 3 (depends on 1)

The tactile presentation device according to claim 1, wherein the vibration part is attached to a rear surface of an other end portion opposite the one end portion of the detection part.

### Claim 4 (depends on 2)

The tactile presentation device according to claim 2, wherein the vibration part is attached to a rear surface of an other end portion opposite the one end portion of the detection part.

### Claim 5 (depends on 2)

The tactile presentation device according to claim 2, wherein the vibration part causes the detection part to vibrate in a direction substantially orthogonal to a longitudinal direction of the detection part.

### Claim 6 (depends on 1)

The tactile presentation device according to claim 1, wherein the vibration part comprises a vibrator on a rear surface of an other end portion opposite the one end portion of the detection part, and
wherein the vibrator is adapted to vibrate at a constant amplitude and frequency.

### Claim 7 (depends on 6)

The tactile presentation device according to claim 6, wherein the detection part is connected to an electronic device to be controlled according to an increase or decrease of a set value, and
wherein the detection part outputs a detection signal for increasing the set value when an operator traces the operation surface in a direction from the one end portion to the other end portion, and the detection part outputs a detection signal for decreasing the set value when the operator traces the operation surface in a direction from the other end portion to the one end portion.

### Claim 8 (depends on 7)

The tactile presentation device according to claim 7, wherein the vibration part is operable to provide the operator with a tactile sensing an increase in vibration of the detection part when the operator traces the operation surface in the direction from the one end portion to the other end portion and to provide the operator with a tactile sensing an decrease in vibration of the detection part when the operator traces the operation surface in the direction from the other end portion to the one end portion.
