  • Second Embodiment A second embodiment is shown in FIG. 12 and FIG. In the second embodiment, while the configuration is the same as that of the first embodiment, the control content for preventing the discomfort is changed.
  • the control unit 130 stops the operation of the drive unit 120 when the finger F moves and exceeds a predetermined position in the intermediate area ca.
  • control unit 130 determines whether the finger F has reached a predetermined position (threshold) in the intermediate area ca (vibration occurrence area).
  • the predetermined position is an intermediate position cp. If it determines with no by S300, control part 130 will perform control of usual pulling in by S310. That is, as shown in FIG. 13, a pull-in vibration is generated, and a vibration is generated so as to increase in magnitude toward the threshold (according to the position of the finger F).
  • control unit 130 performs vibration output for a fixed time in S320 to stop the vibration generation.
  • the intensity of vibration is gradually reduced for a fixed time to stop the vibration.
  • the control unit 130 stops the operation of the drive unit 120 when the finger F exceeds a predetermined position (for example, the middle position cp) in the middle region ca. Therefore, it is possible to give a certain degree of pull-in feeling due to the predetermined vibration, and to make it impossible to give the finger F more vibration addition, thereby making it possible to prevent the operator from feeling uncomfortable.
  • a predetermined position for example, the middle position cp
  • the vibration can be smoothly stopped, and the discomfort due to the sudden stop of the vibration can be eliminated.
  • the intensity of the vibration may be kept constant and stopped.
  • the vibration for retraction control is the vibration that reciprocates in the movement direction of the finger F along the operation surface 111, but instead, the vibration for the operation surface 111 is used.
  • vibration in a crossing (orthogonal) direction may be added with orthogonal vibration (for example, constant vibration intensity).
  • orthogonal vibration for example, constant vibration intensity
  • the input device 100A of the fourth embodiment is shown in FIGS. 14A and 14B.
  • the setting positions of the housing 113 and the drive unit 120 are changed to the housing 113A and the drive unit 120A in the first embodiment.
  • the housing 113A is formed in a plate shape, and is disposed on the back surface side of the operation surface 111.
  • the drive unit 120A is disposed on the back side of the operation surface 111.
  • the drive unit 120A is located between the back side of the operation surface 111 and the housing 113A.
  • the driving unit 120A generates vibration in, for example, two axial directions of the x and y axes, and one driving unit 120A is disposed at a central portion on the back surface side of the operation surface 111.
  • the driving unit 120A uses, for example, an electromagnetic actuator such as a voice coil motor capable of generating vibrations in two axial directions as described in the first embodiment.
  • the number of drive units 120A is not limited to one, and a plurality of drive units may be used.
  • the basic operation is the same as in the first embodiment, and the same effect can be obtained.
  • the vibration control parameter (vibration map) provided in advance is used to control the strength of the vibration, but the present invention is not limited to this, depending on the operation state of the finger F.
  • the vibration pattern may be obtained by calculation.
  • the operation unit 110 is a so-called touch pad type, but the present invention is not limited to this, and a so-called touch panel type in which the display screen 52 of the liquid crystal display 51 is transmitted and visually recognized on the operation surface 111 Is also applicable.
  • a click feeling vibration giving a click feeling is generated.
  • the present disclosure basically generates an induction force (retraction force) by causing the vibration intensity to have a maximum value at an intermediate position cp of the operation area (1111, 1112), and When F is stopped or exceeds a predetermined position, the pull-in vibration is stopped. Therefore, S140 to S160 may be eliminated.
  • the operating body is described as the finger F of the operator.
  • the present invention is not limited to this, and a stick imitating a pen may be used.
