  The contact detection unit 20 is normally disposed on the front side of the display unit 30 and makes contact with an object displayed on the display unit 30 by an operator's finger, stylus pen, or the like (hereinafter simply referred to as “contact object”). , Detection is made on the contact surface of the corresponding contact detector 20. The touch detection unit 20 may be a touch sensor configured by, for example, a resistance film method, a capacitance method, an optical method, or the like.

  The display unit 30 displays an object such as a push button switch (push button switch) or the like as an image. This object is an image that suggests an area to be touched by the contact detection unit 20 to the operator. The push button switch is a button, key, or the like (hereinafter, simply referred to as “key, etc.”) used for operations such as an operator inputting characters or moving a cursor. The display unit 30 is configured using, for example, a liquid crystal display panel (LCD), an organic EL display panel, or the like.

  The control unit 40 controls and manages the entire electronic device 1 by controlling each functional unit constituting the electronic device 1. When the contact detection unit 20 detects contact, the control unit 40 determines that there is a request for tactile sensation based on the detection, and presents the tactile sensation. Specifically, the control unit 40 presents a tactile sensation by vibrating the vibrating unit 10 for a predetermined time.

  In addition, when the vibrating unit 10 is requested to present a tactile sensation, the control unit 40 stops the vibration of the vibrating unit 10 when the vibrating unit 10 is vibrating due to a predetermined event. Preferably, the vibration is stopped for a predetermined time, for example, 0.1 second.

  Next, the operation of the electronic apparatus 1 according to the present invention will be described with reference to the flowchart shown in FIG.

If there is a request for tactile sensation, the process proceeds to step S12. If there is no tactile sensation request, step S11 is repeated.

  Subsequently, when the control unit 40 has requested tactile sensation, the control unit 40 determines whether or not the vibration unit 10 is vibrating due to a predetermined event (step S12). When the vibration part 10 is vibrating, it progresses to step S13. When the vibration part 10 is not vibrating, it progresses to step S14.

  When the vibration unit 10 is vibrating, the control unit 40 stops the vibration of the vibration unit 10 (step S13). Preferably, the vibration is stopped for a predetermined time, for example, 0.1 second. On the other hand, when the vibration part 10 is not vibrating, the control part 40 operates the vibration part 10 for a predetermined time (for example, 0.1 second etc.) and presents tactile sensation (step S14).

  As described above, the control unit 40 determines the vibration state of the vibration unit 10 and stops the operation of the vibration unit 10 when the vibration is in progress, so that the user can recognize that the user operation has been input. It can be recognized by stopping. Therefore, according to the present invention, it is possible to notify the user that a user operation has been input without competing with the vibration during vibration of the vibration unit 10 based on the event.

  When the electronic device 1 according to the modification determines that the vibration unit 10 is vibrating in a normal vibration pattern in step S12, the control unit 40 causes the vibration unit 10 to be a first vibration different from the normal vibration pattern. The pattern is vibrated (step S15). Preferably, the amplitude of the first vibration pattern is set to be distinguishable from the vibration of the vibration unit 10 based on the event by making it larger than the amplitude of a second vibration pattern (normal vibration pattern) described later. .

  On the other hand, if it determines with the vibration part 10 not vibrating in step S12, the control part 40 will vibrate the vibration part 10 by a 2nd vibration pattern (step S16).

  As described above, according to the electronic device 1 according to the modification, the control unit 40 determines the vibration state of the vibration unit 10 and vibrates the vibration unit 10 with a vibration pattern different from the normal vibration pattern when the vibration unit 10 is vibrating. By presenting a tactile sensation, the user can be notified that a user operation has been input without competing with the vibration even during vibration of the vibration unit 10 based on the event.

Is different.

  The pressure detection unit 50 detects pressure on the touch surface of the contact detection unit 20, and for example, a strain gauge sensor or a piezoelectric that changes physical or electrical characteristics (strain, resistance, voltage, etc.) according to the pressure. An element such as an element is used. When the pressure detection unit 50 is configured using, for example, a piezoelectric element or the like, the piezoelectric element of the pressure detection unit 50 is the magnitude (or load) of the load (force) related to the pressure on the touch surface of the contact detection unit 20. In accordance with the speed (acceleration) at which the magnitude of (force) changes, the voltage magnitude (voltage value (hereinafter simply referred to as data)), which is an electrical characteristic, changes.

  The tactile sensation providing unit 60 is configured by using, for example, a piezoelectric vibrator and vibrates the contact detection unit 20. The tactile sensation providing unit 60 presents a tactile sensation to the contact object that is in contact with the contact detection unit 20 by generating vibration according to a predetermined vibration pattern. In the present embodiment, the tactile sensation providing unit 60 generates vibration based on the drive signal supplied from the haptic control unit 72.

When the vibration part 10 is vibrating, it progresses to step S23. When the vibration part 10 is not vibrating, it progresses to step S24.

  When the vibration unit 10 is vibrating, the main control unit 71 stops the vibration of the vibration unit 10 (step S23). Preferably, the vibration is stopped for a predetermined time, for example, 0.1 second.

  Then, the main control unit 71 passes a notification that the vibration of the vibration unit 10 has been stopped to the haptic control unit 72. After receiving the notification, the haptic control unit 72 causes the tactile sensation providing unit 60 to present a tactile sensation (step S24). Specifically, the haptic control unit 72 supplies a drive signal to the tactile sensation providing unit 60, and the tactile sensation providing unit 60 presents a tactile sensation.
