Description

  The present invention relates to an input device that receives input of information when a touch surface is pressed, and an electronic device.

2. Description of the Related Art Conventionally, an input device (screen input device) having a touch panel for detecting a position where a touch surface is exposed to the outside through an opening formed in a case and pressed (operated) by a user on the touch surface is known. (For example, refer to Patent Document 1).
The input device includes a plurality of rubber switches that are pressed by movement of the touch panel by a user's pressing, and is configured to give a sense of moderation to the user when the rubber switches are activated.
The touch panel is moved in parallel (moved so that the touch surface is parallel to the initial position) or tilted against the urging force of the plurality of rubber switches when the touch surface is pressed by the user. (The touch surface moves so as to be inclined with respect to the initial position).

Japanese Patent Laying-Open No. 2003-271307 (FIG. 13)

By the way, among the positions on the touch surface, the parallel movement position at which the touch panel moves in parallel when pressed is provided, for example, by arranging the plurality of rubber switches at positions symmetrical with respect to the center of the touch surface. Generally, it is set at the center of the surface.
For example, when the touch surface is divided into a first region and a second region by a virtual line passing through the center of the touch surface and the first region or the second region excluding the parallel movement position is pressed, the position other than the parallel movement position is Since it will be pressed, a touch panel will carry out an inclination movement.
In addition, since the plurality of rubber switches are arranged at positions symmetrical with respect to the center of the touch surface, the pressing force required to tilt the touch panel (press the rubber switch) (pressing force on the touch surface) ) Is approximately the same pressing force when the first region is pressed and when the second region is pressed.

When a configuration is adopted in which the user operates the input device while checking an image corresponding to each position (coordinate) on the touch surface, the operability is good as shown below. There is a problem that it cannot be obtained.
The image includes an area provided for user operation and an area not provided for operation.
That is, as described above, since the pressing force required to tilt the touch panel in the first and second areas on the touch panel is substantially the same, the image provided for the user's operation is operated. The pressing force at the time is substantially the same as the pressing force at the time of manipulating the image of the area not used for the operation.
Therefore, it is necessary for the user to operate the input device with an unnecessarily large pressing force, and good operability cannot be obtained.

  An object of the present invention is to provide an input device and an electronic apparatus that can obtain good operability.

  The input device according to the present invention can move the surface member between a surface member having a touch surface, a first housing having a first opening that exposes the touch surface to the outside, and the first housing. A second casing sandwiched between the first casing, a position detecting means for detecting a pressed position on the touch surface, the surface member and the second casing, and the surface member is disposed between the first casing and the second casing. The urging member that translates or tilts the surface member in accordance with the pressure on the touch surface while urging the body side, and the amount of movement due to the parallel or tilting movement of the surface member becomes a certain amount or more. A movement detecting means for detecting whether or not the touch switch is disposed at a position facing the center of the touch surface, and when the position is pressed, -The translation position at which the face member translates is the first position shifted from the center of the touch surface when the touch surface is divided into a first region and a second region by a virtual line passing through the center of the touch surface. It is located in the area or the second area.

Here, the parallel movement of the surface member means that the surface member moves so that the touch surface is parallel to the initial position.
Further, the inclined movement of the surface member means that the surface member moves so that the touch surface is inclined with respect to the initial position.

In the present invention, since the input device includes the biasing member described above, the surface member is moved in parallel or inclined in accordance with the pressing on the touch surface, and the surface member is initialized by releasing the pressing on the touch surface. It can be returned to the position.
Further, since the parallel movement position is positioned at the above-described position on the touch surface, the pressing force (the pressing force to the touch surface) necessary for moving the surface member in parallel or tilting is not limited on the touch surface. It will be different at each position.
For example, when a plurality of urging members are provided, the surface member moves in parallel at the parallel movement position, and each urging member needs to be similarly deformed. To do.
On the other hand, except for the parallel movement position, the surface member tilts and there is no need to deform each urging member in the same way, and it is only necessary to deform the urging member disposed on the pressed side. A pressing force smaller than the pressing force at the position is sufficient.

In addition, when the pressing force at each position in the first and second regions is compared, the pressing force at each position in the region where the translation position is not positioned is within the region where the translation position is positioned. It becomes small compared with the pressing force at each position.
Therefore, when adopting a configuration in which the user operates the input device while checking an image corresponding to each position (coordinate) on the touch surface of the pixel, the following effects can be enjoyed.
In the following description, for convenience of explanation, it is assumed that the parallel movement position is located in the first area of the first and second areas.
That is, as the image, if an image provided for the user's operation is arranged corresponding to the second area, and an image not used for the user's operation is arranged corresponding to the first area, Since the pressing force at each position in the second region is relatively small, the user can operate the input device with a small pressing force.
Therefore, it is possible to configure an input device that can obtain good operability.

In the input device according to the aspect of the invention, the movement detection unit may include a push switch that is pressed between the surface member and the second housing, and may be disposed at a position facing the center of the touch surface. preferable.
In the present invention, since the input device includes the above-described push switch disposed at a position facing the center of the touch surface, the amount of operation required for pressing the push switch depending on the position of pressing on the touch surface ( The displacement amount of the surface member in parallel or inclined movement at each position where the touch surface is pressed does not vary greatly. Therefore, it is possible to configure an input device that can obtain better operability.

In the input device according to the aspect of the invention, the movement detection unit may move in parallel or tilt together with the surface member, and the second housing projects toward the first housing, and the surface member is moved in parallel or tilted. It is preferable that a pressing portion for pressing the movement detecting means is provided.
In the present invention, since the movement detecting means (push switch) is attached to the surface member side and the above-described pressing portion is provided on the second housing, the pressing switch contacts the pressing portion when the surface member is moved, The surface member can be favorably tilted using the pressing portion as a fulcrum.

According to another aspect of the invention, there is provided an electronic apparatus including the above-described input device and a second input device having a plurality of operation buttons, wherein the first housing has a second opening that exposes the plurality of operation buttons to the outside. The second region is positioned on the second opening side with respect to the first region, and the parallel movement position is positioned in the first region.
In the present invention, since the electronic apparatus includes the input device described above, it can enjoy the same operations and effects as the input device described above.
The parallel movement position is positioned in the first region located on the side away from the second opening that exposes the plurality of operation buttons to the outside of the first region and the second region.
Accordingly, if the image to be confirmed by the user when operating the input device is configured as described above, the second region where the pressing force is small and the plurality of operation buttons can be arranged close to each other. For this reason, compared with the configuration in which the second region where the pressing force is small and the plurality of operation buttons are arranged apart from each other (the configuration in which the parallel movement position is positioned in the second region), the operation is favorable. It is possible to configure an electronic device that can achieve high performance.

The tip of the convex portion 10B is formed in a spherical shape as shown in FIG. 4 or FIG.

As shown in FIG. 2 or FIG. 5, the clamping member 11 is formed in a substantially rectangular plate shape and is fixed to the back surface of the front case 41, so that the surface sheet 7 (capacitance sheet) is formed between the holding member 11 and the front case 41. 8) is movably held.
As shown in FIG. 2 or FIG. 5, a pressing portion 111 that bulges toward the front case 41 and presses down the tact switch 9 is provided in the clamping member 11 at a position facing the tact switch 9. .

Then, the surface sheet 7 is attached to the front case 41 side by the urging force of the tact switch 9 and the urging member 10 between the front case 41 and the clamping member 11, as shown in FIG. As a result, the tip portion 722A of the second projecting portion 722 comes into contact with the bottom portion of the recess 413 (a state in which it is located at the initial position).
In this state, the surface sheet 7 is disposed such that the touch surface 71A is positioned inside the pad opening 412 as shown in FIG.

In the state described above, when the touch surface 71 </ b> A is pressed against the urging force of the tact switch 9 and the urging member 10 by the observer, the four second protrusions 722 are guided by the side wall portions of the recesses 413. However, the surface sheet 7 moves in parallel or tilts into the exterior housing 4.
When the observer stops pressing the touch surface 71 </ b> A, the surface sheet 7 returns to the initial position by the urging force of the tact switch 9 and the urging member 10.

Hereinafter, in order to distinguish from the second input device 3B, the input device 3A is described as the first input device 3A.

[6. (Setting of translation position)
6 and 7 are diagrams for explaining the parallel movement position P. FIG. Specifically, FIG. 6 is a view of the arrangement positions of the tact switch 9 and the urging member 10 as viewed from the touch surface 71A side. FIG. 7 is a diagram comparing the pixel position of the keyboard screen FG with each position on the touch surface 71A.
In FIG. 6, the protrusion 72 and the overhang 73 are not shown for convenience of explanation.
The translation position P means a position where the surface sheet 7 translates when pressed, among the positions on the touch surface 71A.
In this embodiment, the parallel movement position P is set to be shifted from the center O of the touch surface 71A as shown in FIG. 6 or FIG.

In the following, in the four urging members 10, two urging members 10 located on the upper edge 7U side are referred to as urging members 10U, and the two urging members 10 located on the lower edge 7D side are urging members. 10D (FIG. 6).
In the present embodiment, the two urging members 10U and the tact switch 9 are set to have substantially the same urging force (elastic force).
On the other hand, the two urging members 10D are set to have a urging force (elastic force) smaller than that of the urging member 10U.

By setting the urging forces of the urging members 10U and 10D and the tact switch 9 as described above, the parallel movement position P is set to the two urging members 10U and the tact switch as shown in FIG. 9 is located between the center-of-gravity position Cg at each arrangement position 9 and the arrangement position of the tact switch 9.
That is, as shown in FIG. 6 or FIG. 7, the translation position P is virtually above the touch surface 71A along a virtual line VL that passes through the center O of the touch surface 71A and is parallel to the upper edge 7U or the lower edge 7D. When divided into a first region ArU on the edge 7U side and a second region ArD on the lower edge 7D side, it is positioned in the first region ArU shifted from the center O.

And when the parallel movement position P mentioned above is pressed, the surface sheet 7 will move in parallel as shown below.
That is, since the load applied to each biasing member 10U, 10D and the tact switch 9 by the pressing to the parallel movement position P and each biasing force of each biasing member 10U, 10D and the tact switch 9 can be balanced, the surface sheet 7 moves into the exterior housing 4 so that the touch surface 71A is parallel to the initial position.
On the other hand, when a position other than the parallel movement position P is pressed on the touch surface 71A, the balance described above is lost, so that the surface sheet 7 is inclined with respect to the state at the initial position of the touch surface 71A. Then, it moves (inclined) into the exterior housing 4.

Further, since the parallel movement position P is positioned at the above-described position, the pressing force (to the touch surface 71A) required for moving the surface sheet 7 into the exterior housing 4 (turning on the tact switch 9). ) Is different at each position on the touch surface 71A.
Specifically, at the parallel movement position P, the surface sheet 7 moves in parallel, and the urging members 10U and 10D and the tact switch 9 need to be similarly deformed. Therefore, the largest pressing force on the touch surface 71A is necessary. And
On the other hand, at a position other than the parallel movement position P, the surface sheet 7 is tilted and the urging members 10U and 10D and the tact switch 9 do not need to be similarly deformed, and the urging member 10 disposed on the pressed side. Therefore, a smaller pressing force than the pressing force at the parallel movement position P is sufficient.

Further, among the positions other than the parallel movement position P, the pressing force at each position in the second region ArD is provided with each biasing member 10D having a small biasing force in the second region ArD. A small pressing force is sufficient as compared with the pressing force at each position in the first region ArU in which each urging member 10U having a large urging force is disposed.
In the present embodiment, as shown in FIG. 7, the keyboard screen FG corresponds to the second area ArD in which the surface sheet 7 can be moved with a relatively small pressing force. Each key Ky provided for use is arranged.
On the other hand, as shown in FIG. 7, the keyboard screen FG is used for the operation by the observer in correspondence with the first area ArU that requires a relatively large pressing force to move the surface sheet 7. A character display area ArL that is not to be displayed is arranged.

The embodiment described above has the following effects.
In the present embodiment, since the first input device 3A includes the urging member 10, the surface sheet 7 is moved in parallel or inclined along with the pressing on the touch surface 71A, and the pressing on the touch surface 71A is released. Thus, the surface sheet 7 can be returned to the initial position.

Further, the parallel movement position P is positioned in the first region ArU on the touch surface 71A. In addition, for example, a keyboard screen FG to be confirmed by the observer when the first input device 3A is operated is arranged with a key Ky used for the observer's operation corresponding to the second area ArD. A character display area ArL that is not used for an observer's operation is arranged corresponding to the area ArU.
As a result, the pressing force required for moving the surface sheet 7 at each position in the second region ArD (turning the tact switch 9 to the ON state) becomes relatively small, so that it can be used with a small pressing force. A person can operate the first input device 3A.
Therefore, it is possible to configure the first input device 3A that can obtain better operability.

  In addition, since the first input device 3A includes the tact switch 9 disposed at a position facing the center O of the touch surface 71A, the tact switch 9 is turned on depending on the position of pressing on the touch surface 71A. The amount of operation required for (the amount of displacement that the surface sheet 7 is translated or inclined at each position of pressing on the touch surface 71A) is not greatly different. Therefore, it is possible to configure the first input device 3A that can obtain good operability.

  Further, since the tact switch 9 is attached to the back surface of the capacitance sheet 8 and the pressing member 111 is provided on the clamping member 11, the tact switch 9 abuts on the pressing unit 111 when the surface sheet 7 is moved, and the pressing is performed. The surface sheet 7 can be favorably tilted with the portion 111 as a fulcrum.

The parallel movement position P is positioned in the first region ArU located on the side away from the button opening 411 that exposes the plurality of operation buttons 5 to the outside.
As a result, the second region ArD having a small pressing force and the plurality of operation buttons 5 can be arranged close to each other. For this reason, as compared with the configuration in which the second region ArD and the plurality of operation buttons 5 having a small pressing force are arranged apart from each other (the configuration in which the parallel movement position P is positioned in the second region ArD). Thus, the controller 3 that can obtain good operability can be configured.
