Abstract

An operating device includes a push operation mechanism that allows a push operation of an operation unit, a tactile feeling presenting unit including a drive transmission mechanism for presenting an operational feeling by driving the operation unit via the push operation mechanism, a detection unit that detects a motion of the operation unit, and a drive control unit that intermittently drives the operation unit by a drive control signal that is generated based on an activation pulse signal and an advance vibration pulse signal that includes a prescribed number of pulses and a voltage smaller than that of the activation pulse signal.

Claims

1. An operating device, comprising:

a push operation mechanism that allows a push operation of an operation unit;

a tactile feeling presenting unit comprising a drive transmission mechanism for presenting an operational feeling by driving said operation unit via said push operation mechanism;

a detection unit that detects a motion of said operation unit; and

a drive control unit that intermittently drives said operation unit by a drive control signal that is generated based on an activation pulse signal and an advance vibration pulse signal that comprises a prescribed number of pulses and a voltage smaller than that of said activation pulse signal.

2. The operating device according to claim 1, wherein said drive control unit stops outputting an advance vibration pulse signal after said detection unit detects a motion of said operation unit.

3. The operating device according to claim 1, wherein said drive control unit intermittently drives said operation unit by outputting an additional pulse signal which is larger than said advance vibration pulse signal after outputting said advance vibration pulse signal if said detection unit doesn'"'"'t detect a motion of said operation unit when the prescribed time elapses.

4. The operating device according to claim 2, wherein said drive control unit presents an operational feeling by a main vibration control to drive said operation unit by said drive transmission mechanism via said push operation mechanism after said detection unit detects a motion of said operation unit.

5. The operating device according to claim 2, wherein said advance vibration pulse signal is set as a pulse line the voltage value or the pulse width of which gradually increases.

6. The operating device according to claim 3, wherein said activation pulse signal comprises a plus pulse a direction of which is equal to a direction of driving said operation unit and a minus pulse a polarity of which is opposite to that of said plus pulse.

7. The operating device according to claim 1, wherein said operation unit comprises a touch panel.

8. The operating device according to claim 1, wherein said drive transmission mechanism comprises a rotary drive means and a cam mechanism.

9. The operating device according to claim 8, wherein said push operation mechanism comprises a linking member supported by a body to which the operation unit is attached, and

wherein said cam mechanism is configured to be rotatable between an engagement position to transmit a drive force of the rotary drive means to the linking member and a non-engagement position not to transmit the drive force of the rotary drive means to the linking member.

10. The operating device according to claim 8, wherein said cam mechanism is configured to convert a rotary motion of the rotary drive means into a reciprocating motion of the operation unit.
