  However, in the background art of Patent Document 2, although only a few operating bodies to be used can be protruded from the surface of the operation panel, a polymer actuator is used as the means for protruding, so that the repulsive force is weak. For this reason, there is a problem that the feeling of pressing when the operating body is operated is weak.

  The present invention solves the above-described problems, and an object of the present invention is to provide an input device and an input device that can provide a strong pressing feeling when an operating body that protrudes from an operation surface is operated.

In order to solve this problem, the input device of the present invention includes an operation body capable of moving up and down between a predetermined upper point and a lower point so that the head protrudes from the surface of the operation surface during ascending. An actuator that presses the body and raises the operating body; and a movable member that is movable to a position that inhibits the operating body from descending when the actuator is operated and the operating body is raised. has the movable member, when the operating body is pressed in the direction of Fudo the head, Ri Do an elastic member which expresses a biasing force in a direction to push back the operating member, the operating body Has a first notch for accommodating a part of the movable member when the operating body is at the lower point, and the first notch is configured to accommodate a part of the movable member. It is characterized by having a shape that inhibits the lifting of the operating body .

According to this, in the input device of the present invention, when the operation body is pushed down, the operation body comes into contact with the movable member in the middle of pushing down, and in addition to the repulsive force of only the actuator, the repulsive force from the movable member Therefore, it is possible to obtain a strong pressing feeling when the operating body is pressed down. Furthermore, when the operating body is at the lower point and a part of the movable member is accommodated, a part of the movable member obstructs the ascending of the operating body. Even if no other protrusion prevention mechanism is provided, it is possible to prevent the operation body at the lower point from protruding from the surface of the operation surface.

  The input device of the present invention is characterized in that the movable member has a click portion that generates a click feeling when the head of the operating body is pressed in the descending direction.

  According to this, when an operation of depressing the operating body is performed, a click feeling is obtained by the action of the click part, and thus a pressing feeling that the operating person has surely operated the input device is obtained.

  In the input device according to the present invention, the actuator includes a first electrode layer and a second electrode layer arranged to face each other, and an electrolyte layer provided between the first electrode layer and the second electrode layer. And a polymer actuator that is deformed in response to an electric field between the first electrode layer and the second electrode layer.

Moreover, the input device of the present invention is suitably used for an input device including a plurality of operation bodies, and can project or store only a desired operation body. Further, since the movable members are integrally formed, all of the movable members can be moved by a single operation, so that it is not necessary to provide a complicated mechanism for each operation body. In addition, since the movable member is accommodated in the first cutout portion of the operating body that is not lifted, the movable member can be moved to a position that hinders the raised operating body, and protrudes from the operating surface. In addition, when operating several operating bodies that are desired to be used, a pressing feeling or a clicking feeling can be obtained. Therefore, the present invention can provide an input device and an input device that can obtain a pressing sensation or a clicking sensation when operating several operating bodies desired to be used that protrude from the operation surface.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[First Embodiment]
FIG. 1 is a diagram illustrating the configuration of the input device 101 according to the first embodiment of the present invention, and is a plan view seen from the operation surface 15 side. 2A is a cross-sectional view taken from the X1 side of the II line shown in FIG. 1, and FIG. 2B is a cross-sectional view taken from the Y2 side of the II-II line shown in FIG. is there. FIG. 3 is a diagram illustrating an example of the operation state of the input device 101 according to the first embodiment of the present invention. FIG. 3A is a configuration diagram illustrating a state where the operating body 11 is at the lower point BDC. FIG. 3B is a configuration diagram showing a state in which the operating body 11 is at the upper point TDC.

  As shown in FIGS. 1 to 3, the input device 101 includes an operating body 11, an actuator 2, and a movable member 14, and is housed in a casing 8 that is a synthetic resin or metal exterior body. Yes. The operating body 11 is supported by the actuator 2 and can move up and down from the lower point BDC shown in FIG. 3A to the upper point TDC shown in FIG. At the upper point TDC shown in (b), the head 11 h of the operation body 11 protrudes from the operation surface 15 of the operation panel 5.

  The operating body 11 has a shape and size that can be pressed with a finger or the like for switch operation, and has a rectangular parallelepiped shape. The operation body 11 is made of general-purpose plastics such as ABS resin and polyethylene (PE). The shape and material of the operation body 11 are not limited to a rectangular parallelepiped shape or general-purpose plastics as long as the switch operation is secured and sufficient strength is obtained. In addition, a stopper 7 is provided between the operating body 11 and the actuator 2 so that the stopper 7 and the operation panel 5 are in contact with each other to prevent the operating body 11 from being detached from the housing 8.

  The actuator 2 supports the operating body 11 and operates the actuator 2 so that the operating body 11 can be moved up and down by pressing the operating body 11. The operation of the actuator 2 is performed by a separately provided control circuit unit (not shown). Further, when the operating body 11 is pressed downward by a finger or the like for switch operation, the actuator 2 is elastically deformed while increasing a repulsive force that presses the operating body 11. The actuator 2 may be a simple mechanism for moving the operating body 11 up and down and an actuator that elastically deforms when the operating body 11 is pressed downward. In particular, a polymer actuator is preferably used. .

  FIG. 4 is a schematic diagram illustrating an example of the ion conductive polymer actuator 2P among the polymer actuators. As shown in FIG. 4 (a), the ion conductive polymer actuator 2P includes a first electrode layer 12 and a second electrode layer 22 which are disposed to face each other, the first electrode layer 12 and the second electrode layer. And an electrolyte layer 32 provided between the electrode layer 22 and the electrode layer 22. The electrolyte layer 32 is a gel-like film in which an ionic liquid is mixed with a base polymer, and the first electrode layer 12 and the second electrode layer 22 are the same base polymer and ionic liquid as the electrolyte layer 32, and a conductive filler. Are mixed to form a gel. For example, polyvinylidene fluoride can be used as the base polymer. In addition, as the conductive filler, carbon nanotube, carbon fiber, or the like can be used.

  As shown in FIG. 4B, when a voltage is applied to the first electrode layer 12 and the second electrode layer 22, they are sandwiched between the first electrode layer 12 and the second electrode layer 22. An electric field is generated in the electrolyte layer 32, and the cation CA moves to the first electrode layer 12, and the anion AN moves to the second electrode layer 22. Therefore, in the direction of the electric field of the polymer actuator 2P. Accordingly, the polymer actuator 2P is displaced. Further, by changing the strength of the electric field applied to the polymer actuator 2P, the amount of deformation that is deformed according to the electric field can be changed.

  When the polymer actuator 2P is applied to the actuator 2 of the input device 101 according to the first embodiment of the present invention, the polymer actuator 2P fixes the center of the polymer actuator 2P as a fulcrum as shown in FIG. Thus, both ends are bent and deformed upward. Thereby, the operating body 11 can be moved, and the operating body 11 can be moved up and down to an arbitrary position by changing the strength of the electric field. Accordingly, it is possible to easily move the operating body 11 up and down by operating the polymer actuator 2P without applying a complicated mechanism simply by applying an electric field to the polymer actuator 2P.

  As shown in FIG. 2, the movable member 14 is disposed at a position where the operation body 11 is prevented from descending when the operation body 11 is moved up. Further, in order to cause the operating body 11 to protrude from the operating surface 15, when the operating body 11 is raised, the movable member 14 moves to a position that does not prevent the operating body 11 from being lifted. The movable member 14 also moves to a position that does not prevent the operating body 11 from descending when the operator 11 is descended. These series of operations are performed by controlling a driving unit such as a motor, for example, that drives the movable member 14 in conjunction with a control circuit unit that controls the operation of the actuator 2 by the operation control unit.

  Further, the movable member 14 has a biasing force in a direction to push back the operation body 11 when the operation body 11 descends and comes into contact with the movable member 14 when the head 11h of the operation body 11 is pressed for the switch operation. It consists of an elastic member that develops. As the shape of the movable member 14, as shown in FIGS. 1 and 2, a plate shape is preferably used, but various shapes such as a rod shape, a dome shape, and a U-shape can be used. The movable member 14 is made of synthetic resin, metal, or the like, but stainless steel, phosphor bronze, steel, or the like that is usually used as a leaf spring material is preferably used.

  FIG. 5 is a diagram illustrating an example of the operation state of the input device 101 according to the first embodiment of the present invention. FIG. 5A is a configuration diagram illustrating a state where the operating body 11 is at the upper point TDC. FIG. 5B is a configuration diagram showing a state in which the operating body 11 is moved downward by a finger or the like for the switch operation and is in contact with the movable member 14, and FIG. It is a block diagram which shows the state which moved down further and the movable member 14 deform | transformed.

  In order to project the usable operating body 11 from the operating surface 15, when the operating body 11 is moved up by operating the actuator 2 from the lower point BDC shown in FIG. Move to a position that does not hinder the ascent. Then, when the operating body 11 is moved up to the upper point TDC shown in FIG. 3B, the movable member 14 is positioned at a position that inhibits the lowering of the operating body 11 as shown in FIG. 5A. Moving. When the operating body 11 is pressed downward from the upper point TDC shown in FIG. 5A by a finger or the like for switch operation, the actuator 2 increases the repulsive force that presses the operating body 11. Elastically deforms. Further, the operating body 11 is moved downward, and the operating body 11 comes into contact with the movable member 14 as shown in FIG. Furthermore, when the operating body 11 is moved downward, the movable member 14 is elastically deformed while increasing the repulsive force that presses the operating body 11 as shown in FIG. Then, after the switch is turned on or off, when the downward pressing applied to the operating body 11 is released, the operating body 11 is pushed back by the repulsive force of the movable member 14 and the actuator 2, and FIG. The operating tool 11 returns to the state of the upper point TDC shown in a).

  With the above operation, when the operating body 11 is pressed downward with a finger or the like for switch operation, in addition to the repulsive force of the first actuator 2, the repulsive force of the movable member 14 is applied midway. As a result, when the operation body 11 is pushed down, the operation body 11 comes into contact with the movable member 14 while the operation body 11 is being pushed down, and the repulsive force from the movable member 14 is added to the repulsive force of only the actuator 2. A strong pressing feeling when the operation body 11 is pushed down can be obtained. For example, when a 7 mm wide polymer actuator 2P is used for the actuator 2 and a stainless steel spring material having a thickness of 0.5 mm is used for the movable member 14, the initial repulsive force is about 200 mN, and the repulsive force from the middle is It became 1000 mN or more.

  As described above, the input device 101 of the present invention pushes back the operating body 11 when the head 11h of the operating body 11 is pressed for the switch operation and the operating body 11 descends and comes into contact with the movable member 14. Since the repulsive force from the movable member 14 is added in addition to the repulsive force of the actuator 2 alone, a strong pressing feeling when the operating body 11 is pushed down is obtained. Be able to.

  In addition, the actuator 2 includes a first electrode layer 12 and a second electrode layer 22 that are arranged to face each other, an electrolyte layer 32 provided between the first electrode layer 12 and the second electrode layer 22, Since the polymer actuator 2P is deformed according to the electric field between the first electrode layer 12 and the second electrode layer 22, a complicated mechanism is provided only by applying an electric field to the polymer actuator 2P. The operating body 11 can be easily moved up and down by operating the polymer actuator 2P.

  As shown in FIG. 6, the movable member 24 has a click portion 24 c on both sides of the actuator 2 so as to sandwich the actuator 2, and is arranged at a position that inhibits the operation body 11 from descending. In addition, the click part 24c has a gently curved surface whose center part is convex downward (not shown) with respect to the width direction orthogonal to the longitudinal direction, and reverses when a certain load is applied from the upper side. It is like that.

  The input device 102 according to the second embodiment of the present invention performs the same operation as the operation illustrated in FIGS. 5A to 5C of the input device 101 according to the first embodiment of the present invention, and the movable member 24. 7 is elastically deformed while increasing the repulsive force that presses the operating body 11 as shown in FIG. When further pressed downward, as shown in FIG. 7B, the click portion 24c of the movable member 24 is reversed and the repulsive force is temporarily reduced. Then, after the switch is turned on or off, when the downward pressing applied to the operating body 11 is released, the operating body 11 is pushed back by the repulsive force of the movable member 24 and the actuator 2, and FIG. The operating tool 11 returns to the state of the upper point TDC shown in c). Moreover, the click part 24c of the movable member 24 reverses reversely, and the elastic deformation of the movable member 24 is eliminated.

  With the above operation, when the operating body 11 is pressed downward with a finger or the like for switch operation, in addition to the repulsive force of the first actuator 2, the repulsive force of the movable member 24 is applied from the middle. Due to the reversal of the portion 24c, the repulsive force temporarily decreases. As a result, when an operation of depressing the operating body 11 is performed, a click sensation is obtained by the action of the click part 24c in the middle of depressing.

  As described above, the input device 102 of the present invention has the click portion 24c that generates a click feeling when the movable member 24 presses the head 11h of the operating body 11 in the descending direction. Since the click sensation is obtained by the action of the unit 24c, a pressing sensation that the person who operates the device has operated the input device 102 with certainty is obtained.
