  However, in the above-described conventional example, when the input device is applied to a device used in an environment in which vibration is applied from the surroundings, such as a vehicle-mounted device, the large key (operation unit) 921 having the input pad 924 vibrates due to vibration. There is a risk of it. In addition, even when vibration is applied to the input device, when a hard spring is used as the reinforcing spring S so that the large key (operation unit) 921 does not vibrate, the resistance force when the large key 921 is pressed increases.

  Next, the electrical configuration of the input device 100 will be described with reference to FIG. FIG. 7 is a block diagram showing an electrical configuration of the input device 100.

  As shown in FIG. 7, the input device 100 includes an operation unit 1, a press detection unit 11, a control unit 12, an electromagnetic solenoid 4, a current supply unit 13, and a coil 7.

  A coordinate input unit 1 a provided in the operation unit 1 is connected to the control unit 12, detects the contact position of the operation body 500, and determines an electrical state such as a capacitance or a resistance value according to the operation state. The change is converted into current, voltage, etc. and output to the control unit 12.

  The press detection unit 11 is connected to the control unit 12, and contact / separation of the contact is switched according to the pressure when the pressing operation unit 11 a is pressed, or an electric current due to a change in electric resistance, capacitance, voltage, or the like. A signal is generated and output to the control unit 12.

  The control unit 12 is connected to the coordinate input unit 1 a, the press detection unit 11, the electromagnetic solenoid 4, and the current supply unit 13. Based on the detection result of the coordinate input unit 1 a, the control unit 12 controls the current supply unit 13 to supply a current to the coil 7 when it is determined that the operating body 500 is in contact with the coordinate input unit 1 a. In addition, the control unit 12 can process the detection result of the press detection unit 11 and detect that the operating body 500 is pressing the operation unit 1. The control unit 12 outputs a control signal to the external device 600 based on the detected operation coordinates of the operating body 500 and the presence / absence of a pressing operation, or outputs a drive signal to the electromagnetic solenoid 4 to cause vibrations to the operation. Feedback to the operator can be performed.

  The current supply unit 13 is connected to the control unit 12 and the coil 7, and supplies or stops current to the coil 7 based on the control of the control unit 12.

  The coil 7 is connected to the current supply unit 13, and is configured such that when the current supply unit 13 supplies current to the coil 7, the magnetic pole generated in the coil 7 is opposite to the magnetic pole of the permanent magnet 5.

  Next, the operation of the input device 100 will be described with reference to FIGS.

  First, an operation when the input device 100 is not operated and no current is supplied to the coil 7 will be described. The magnetic force generated by the permanent magnet 5 is shown in FIG. 6B by a dashed arrow, from the N pole as the first magnetic pole to the first yoke 8, the first extending portion 6 b of the magnetic path constituting member 6, It reaches the S pole, which is the second magnetic pole, through the outer peripheral portion 6a, the second extending portion 6c, and the second yoke 9.

  The force attracted by the magnetic force generated by the permanent magnet 5 and the permanent magnet 5 in which the first yoke 8 and the second yoke 9 are arranged is supported by the support member 4b supporting the permanent magnet 5. When moving along the first movable direction, the distance D1 is the maximum when the distance D2 is the same. As described above, the distance D1 between the first yoke 8 and the first extending portion 6b is arranged to be larger than the distance D2 between the second yoke 9 and the second extending portion 6c. Therefore, the permanent magnet 5 has a force F directed toward one side (Z1) so that the force attracted by the magnetic force is maximized.

  Since the magnetic path constituent member 6 is fixed to the housing 2, the force F toward the one (Z1) side generated by the magnetic force of the permanent magnet 5 is applied to the support member 4b and the support member 4b on which the permanent magnet 5 is supported. The urging force (F) that urges the operating portion 1 toward one side (Z1) together with the transmission member 3 being held is provided. The urging force is an operating force when the operator presses the operation unit 1 against the urging force.

  Next, an operation when it is determined that the operating body 500 has come into contact with the coordinate input unit 1a and current is supplied from the current supply unit 13 to the coil 7 will be described. When a current is supplied to the coil 7, the magnetic pole generated in the coil 7 is opposite to the magnetic pole of the permanent magnet 5, so one (Z1) side of the first direction (Z 1 -Z 2 direction) of the coil 7 becomes the S pole, The other (Z2) side is the N pole. For this reason, the magnetic force generated by the coil 7 is shown in FIG. 6 (c) by the second extending portion 6c and the second extending portion 6c of the magnetic path constituting member 6 from the N pole generated by supplying the current, 2 reaches the south pole through the yoke 9, the permanent magnet 5, the first yoke 8, and the third extending portion 6d.

  The support member 4b that supports the permanent magnet 5 is movable because the permanent magnet 5 in which the first yoke 8 and the second yoke 9 are arranged and the magnetic path component 6 attract each other by the magnetic force generated by the coil 7. If the distance D3 and the distance D2 are the same when moving along the first direction, the maximum value is obtained. The magnetic force generated by the coil 7 is opposite to the magnetic force generated by the permanent magnet 5, and acts to reduce the magnetic force generated by the permanent magnet 5. As described above, the distance D3 between the first yoke 8 and the third extending portion 6d is larger than the distance D2 between the second yoke 9 and the second extending portion 6c. Therefore, a force R directed toward the other (Z2) side is generated between the permanent magnet 5 and the magnetic path constituting member 6 so that the force attracted by the magnetic force generated by the coil 7 is maximized. The current supplied to the coil 7 is set so that the force attracted by the magnetic force generated by the coil 7 is smaller than the biasing force generated by the permanent magnet 5, and the force R generated by the magnetic force generated in the coil 7 is the force F generated by the permanent magnet 5. Smaller.

  Since the magnetic path constituting member 6 is fixed to the casing 2, the force R generated by the magnetic force of the coil 7 toward the other (Z2) side acts as a small reaction force with respect to the urging force generated by the magnetic force of the permanent magnet 5. To do. As a result, the supporting member 4b that supports the permanent magnet 5 and the urging force that urges the operation unit 1 to one side (Z1) together with the transmission member 3 held by the supporting member 4b are generated by the permanent magnet 5. It is given by the combined force of the force F toward the (Z1) side and the reaction force R generated by supplying a current to the coil 7.

  In this way, by supplying current to the coil 7, the force F generated by the permanent magnet 5 is canceled out by the reaction force R generated by the coil 7, so that the operation unit is operated only when the operation unit 1 is pressed. The urging force applied to 1 is weakened, and the pressing operation is facilitated. As a result, an urging force (operation force) with good operability can be applied. Further, since the magnitude of the reaction force R can be set by changing the magnitude of the current supplied to the coil 7, a desired biasing force (operation force) can be easily set.

  When the operation unit 1 is pressed beyond the urging force, the support member 4b moves to the other side in the first direction (Z1-Z2 direction) via the transmission member 3, and the drive unit 4e is pressed. The force P by the pressing operation is transmitted to the pressing operation unit 11a. The press detection unit 11 switches contact / separation according to the pressure when the pressing operation unit 11a is pressed, or generates an electrical signal due to a change in electrical resistance, capacitance, voltage, or the like to generate a control unit 12. Output to. The control unit 12 detects a pressing operation based on the electrical signal output from the pressing detection unit 11, and operates as an input device corresponding to the pressing signal by outputting a control signal corresponding to the pressing operation to the external device 600. . In addition, by outputting a drive signal for driving the electromagnetic solenoid 4 in response to the pressing operation, it is possible to feed back a tactile sense due to vibration to the operation.

  Hereinafter, the effect by having set it as this embodiment is demonstrated.

  In the input device 100 of the present embodiment, the operation unit 1 that can be pressed by the operating body 500, the press detection unit 11 that detects that the operation unit 1 has been pressed, and the operation unit 1 in the first direction (Z1). -Z2 direction) and a support member 4b capable of reciprocating in the first direction (Z1-Z2 direction) integrally with the operation unit 1 and the first support member 4b. A housing 2 having a restricting portion 22b for restricting movement to one side (Z1) in the direction (Z1-Z2 direction) at a predetermined position, and a control portion 12 for processing the detection result of the press detection portion 11. The support member 4b is held by the support member 4b so as to surround the periphery of the support member 4b with a surface orthogonal to the first direction (Z1-Z2 direction), and one (Z1) side of the first direction (Z1-Z2 direction) is the first. The other pole (Z2) is the second pole (S pole). The magnetized permanent magnet 5 is held by the housing 2 and is disposed so as to surround the periphery of the permanent magnet 5 with a plane orthogonal to the first direction (Z1-Z2 direction). A magnetic path constituent member that generates an attractive force, a coil 7 disposed in the magnetic path constituent member 6, and a current supply unit 13 that supplies or stops current to the coil 7. Reference numeral 6 denotes the outer peripheral portion 6a and one (Z1) side in the first direction (Z1-Z2 direction) of the outer peripheral portion 6a to one side (Z1) side in the first direction (Z1-Z2 direction) of the permanent magnet 5. The first extending portion 6b that is extended and the other end (Z2) side of the outer peripheral portion 6a are extended toward the other (Z2) side of the first direction (Z1-Z2 direction) of the permanent magnet 5. The coil 7 is disposed between the first extension 6b and the second extension 6c of the magnetic path component 6. The permanent magnet 5 is between the first extending portion 6b and the second extending portion 6c, and the supporting member 4b is moved in the first direction (Z1-Z2) by the magnetic force generated by the permanent magnet 5. When the current supply unit 13 supplies current to the coil 7, the magnetic force generated in the coil 7 causes the support member 4b to move in the first direction (Z1−). A reaction force R smaller than the biasing force is generated on the other (Z2) side in the Z2 direction).

  Accordingly, the biasing force (F) that can prevent the vibration of the operation unit 1 even when vibration is applied by the magnetic attraction force generated between the permanent magnet 5 and the magnetic path constituting member 6 in the first direction. It can give to the operation part 1 toward one side (Z1) of (Z1-Z2 direction). Further, when the current supply unit 13 supplies current to the coil 7, the urging force (F) is reduced by the reaction force R, so that the pressing operation can be performed without impairing the operability. Therefore, it is possible to provide an input device that can prevent vibration of the operation unit 1 even when vibration is applied from the surroundings while maintaining good operability. Further, since the magnitude of the reaction force R can be set by changing the magnitude of the current supplied to the coil 7, a desired biasing force (operation force) can be easily set.

  In the input device 100 according to the present embodiment, the magnetic path component member 6 includes the first extending portion 6b and the second extending portion between the first extending portion 6b and the second extending portion 6c. A third extending portion 6d extending from the outer peripheral portion 6a is provided along the setting portion 6c, and the coil 7 is disposed between the second extending portion 6c and the third extending portion 6d. The first yoke 8 is disposed on one (Z1) side of the first direction (Z1-Z2 direction) of the permanent magnet 5, and the second yoke 9 is disposed on the other (Z2) side. The yoke 8 and the second yoke 9 are disposed between the first extending portion 6b and the second extending portion 6c, and the restricting portion 22b is provided with the first yoke 8 and the first extending portion 6b. The distance D1 between the first yoke 8 and the third extending portion 6d is greater than the distance D2 between the second yoke 9 and the second extending portion 6c. So that it grows It has a configuration which restricts the movement in the first direction of the member 4b (Z1-Z2 direction).

  Thus, the distance D1 between the first yoke 8 and the first extending portion 6b is made larger than the distance D2 between the second yoke 9 and the second extending portion 6c by the restricting portion 22b. Since the support member 4b is regulated, a stable urging force (F) can be applied. Further, the distance D3 between the first yoke 8 and the third extending portion 6d is arranged to be larger than the distance D2 between the second yoke 9 and the second extending portion 6c. Therefore, when the current supply unit 13 supplies a current to the coil 7, a desired reaction force R can be obtained with a small current.

  Moreover, in the input device 100 of this embodiment, the coordinate input part 1a which detects the contact position of the operation body 500 is formed in the surface of the operation part 1, and the control part 12 is based on the detection result of the coordinate input part 1a. When it is determined that the operating body 500 is in contact with the coordinate input unit 1 a, the current supply unit 13 is controlled to supply current to the coil 7.

  Thereby, when a contact with the coordinate input unit 1a provided in the operation unit 1 is detected, a current is supplied to the coil 7, so that when the pressing operation is performed on the operation unit 1, the urging force (F) is surely applied. Can be reduced. Further, when no contact is detected, no current is supplied to the coil 7 and the urging force (F) is not reduced, so that the operation unit 1 can be prevented from vibrating even if vibration is applied.

  In addition, the input device 100 according to the present embodiment includes the electromagnetic solenoid 4 having the main body portion 4a, and the support member 4b is disposed on the main body portion 4a at one end (Z1 side) in the first direction (Z1-Z2 direction). The main body 4a is fixed to the housing 2 and is supported so as to be reciprocally movable in the first direction (Z1-Z2 direction).

  Accordingly, since the electromagnetic solenoid 4 having the support member 4b that can reciprocate in the first direction (Z1-Z2 direction) is provided, it is possible to give the operator an operational feeling due to vibration when an operation is detected. Moreover, since the support member 4b is provided in the electromagnetic solenoid 4, it is not necessary to use another component, and a structure becomes simple.
