Description

  The present invention relates to an input device capable of analog output by pressing an operating body, and in particular, can obtain different output operations depending on the pressing position of the operating body, and is used for obtaining an analog output and a digital output. The present invention relates to an input device that can clearly separate operations.

Patent Document 1 listed below discloses an input device for game machines.
FIG. 9 is a cross-sectional view showing an operation lever provided in the game machine input device. The back side of the paper is the + Y direction, and the front side of the paper is the -Y direction.

As shown in FIG. 9, when the operation lever 101 is tilted in the −X direction, the operation point Q of the operation lever 101 moves in the −X direction and deviates from the position when it is on the neutral axis N during non-operation. Move to position. In this state, of the conductive elastic bodies 102 a and 102 b, the conductive elastic body 102 a in the −X direction of the movement transmitting member 103 is pushed downward by the movement transmitting member 103. Then, the conductive elastic body 102a contacts the resistor 104a corresponding to the conductive elastic body 102a among the resistors 104a and 104b. The contact area between the conductive elastic body 102a and the resistor 104a corresponds to the amount of movement of the operation lever 101. For this reason, at the location between the conductive elastic body 102a and the resistor 104a, the resistance value changes due to the change in the contact area, and the current flowing through the resistor 104a changes. By looking at the voltage change from the change in current, the azimuth and the tilt angle that moved the operating point Q of the operating lever 101 are detected. The detected signal is input as an analog signal from the flexible board 105 to the computer game machine via a cable or the like.

  However, in the invention described in Patent Document 1, a change in the contact area between the conductive elastic body 102a and the resistor 104a can be detected, but the contact point where the conductive elastic body 102a and the resistor 104a are in contact with each other. The contact position in the XY plane of the resistor 104a cannot be detected.

  For example, in order to increase the types of games that can be operated, it is necessary to be able to obtain both the analog output and the digital output. However, in the invention described in Patent Document 1, in order to obtain not only the analog output but also the digital output by tilting the operation lever 101, for example, digital output is provided between the resistors 104a and 104b and the plate 106. Even if a member such as a switch is provided, in order to obtain an analog output and a digital output separately, for example, when obtaining a digital output, the tilting amount of the operation lever 101 is increased to obtain an analog output. Sometimes it is necessary to reduce the amount of tilt of the operation lever 101. That is, the amount of tilt of the operation lever 101 must be changed with a finger or the like. It is difficult to change the amount of tilting with a finger or the like.

  The present invention solves the above-described conventional problems, and can obtain different output operations depending on the pressed position of the operating body, and can clearly separate an operation for obtaining an analog output and an operation for obtaining a digital output. The object is to provide a device.

The present invention includes an operation member having a plurality of operation members extending radially, and the elastic pressing member that is elastically deformed by a pressing operation on the operation member, by being deformed by the elastic pressing member, each of the operation An input device provided with detection means for outputting a detection signal according to a position and a direction in which a pressing operation is performed on the body ,
It said detecting means includes a plurality of resistance members extending in the same radial direction as the operating body, and the connection electrode for electrically connected respectively inner circumferential side of the end portion to each other or the outer peripheral side end portion each other of the resistive member of multiple, It is opposed to the resistance member, and by the pressing operation is provided and the counter electrode are found in contact with the resistance member, from the end portion of the resistive member to a contact position between the resistor member and the counter electrode the detection signal in accordance with the resistance value is outputted is characterized in Rukoto.

  In the present invention, since the position of the pressed portion in the radial direction on the operating body can be output in an analog manner, different output operations can be obtained depending on the position at which the operating body is pressed. For example, when the inner part of each operating body is continuously pressed in the circumferential direction of the concentric circle, an output with a high operation speed can be obtained, and the outer part of each operating body is continuously connected in the circumferential direction of the concentric circle. When it is pressed automatically, an output with a slow operation speed can be obtained.

  In the above, it is preferable that a plurality of the counter electrodes are provided and each of the counter electrodes is arranged to face each of the resistance members.

  If it arrange | positions in this way, only the resistance member which opposes the counter electrode which deform | transformed below corresponding to the pressed operation body among several resistance members will contact with a counter electrode. For this reason, it is provided at the same time as the counter electrode provided below the operating body to be pressed, and below the operating body that should not be pressed, for example, the adjacent operating body. It is possible to prevent the counter electrode being pressed from being accidentally pressed.

  In addition, it is preferable that the resistance member is formed in a shape in which the width dimension gradually increases in the radial direction from the inner peripheral side toward the outer peripheral side.

  With this shape, if the boundary (position to be used as a threshold value) for discriminating between the inner peripheral side and the outer peripheral side is set to a position on the outer peripheral side with respect to the middle point of the resistance member, the inner peripheral side functions. Since the operation area can be enlarged and a wider resolution can be obtained, the operability on the inner peripheral side can be improved.

  In the present invention, it is preferable that a reversing switch is provided on the lower side of the detecting means and at a position facing the plurality of operating bodies extending in the radial direction, and a protrusion is provided on the lower surface of the operating member. It is preferable that the reversing switch be reversed when pressed by the protrusion.

  According to the above means, when the operating member is pressed, the operator can be given a click feeling, so that the switch can be clearly recognized. Further, since the switch is provided, an analog output can be obtained on the detection means side, and an on / off digital output can be obtained on the switch side.

  Further, it may be configured to have switching means for applying a predetermined voltage to both ends of the plurality of resistance members at a predetermined period, and voltage detection means for detecting a voltage generated at the counter electrode at a predetermined period.

  In the above means, the operation direction and the operation position corresponding to the pressing operation given to the operation member can be detected as a voltage.

  In the input device of the present invention, different output operations can be obtained depending on the pressed position of the operating body, and operations for obtaining an analog output and operations for obtaining a digital output can be clearly separated.

When the outer peripheral side is operated, FIG. 6B shows a case where the inner peripheral side is operated. FIG. 7 shows the output waveform of the input device when a pressing operation is continuously given to each operating body at a constant speed . FIG. 7A shows a case where the inner peripheral side is operated, and FIG. 7B shows a case where the outer peripheral side is operated. Is shown. In addition, the dotted line part in FIG. 4 has shown the center switch provided below the center operation part.

  As shown in FIGS. 1 and 2, the input device 10 has an operation member 20 formed of synthetic resin or the like. As shown in FIG. 1, the operating member 20 has a central operating portion 20A and operating bodies 21, 22, 23, 24, 25, 26, 27 and 28 extending radially in 8 directions.

  As shown in FIG. 2, a central protrusion 20a is formed below the central operation portion 20A. A slit-like recess 20c is formed on each of the lower surfaces 20b of the operating bodies 21 to 28, and a protrusion 20d is formed in the vicinity of each recess 20c.

  Elastic pressing members 13 are provided below the operating bodies 21 to 28, respectively. As shown in FIG. 2, the elastic pressing member 13 is formed of a material such as synthetic rubber or silicone rubber whose cross-sectional shape is concave with respect to the operating body and which can be compressed and deformed. Each elastic pressing member 13 is integrally formed with an elastically deformable rib 13d, and the elastic pressing member 13 and the rib 13d are integrally formed of the same material. The rib 13d prevents the elastic pressing member 13 from tilting.

  Further, an insertion hole 13a penetrating in the Z1-Z2 direction is formed at the center of the elastic pressing member 13, and the central protrusion 20a of the central operation portion 20A is inserted into the insertion hole 13a from above. In the insertion hole 13a, the diameter of the opening is formed smaller than the diameter on the insertion side, and in the central protrusion 20a, the diameter on the tip side is formed larger than the diameter on the base side. For this reason, it is difficult for the operating member 20 to come out of the elastic pressing member 13 when the central protruding portion 20a is inserted into the insertion hole 13a.

  As shown in FIG. 2, the upper edge portion 13 c of the elastic pressing member 13 is in contact with the operation member 20. That is, the upper edge portion 13c has a flat shape and comes into contact with the flat surface of the lower surface 20b of the operation bodies 21 to 28. When the operation member 20 is pressed, only the upper edge portion 13c is moved by the operation member 20. Pressed.

  In the present invention, the elastic pressing member 13 is formed thin, and as shown in FIG. 2, when the operation member 20 is not operated, the protruding portion 20 d is separated from the lower top portion 13 b 1 of the elastic pressing member 13. It is in.

  A sheet substrate 14 is provided on the lower surface of the elastic pressing member 13. As shown in FIG. 3, the sheet substrate 14 is formed of a lower sheet 14a and an upper sheet 14b. The sheet substrate 14 is provided with detection means 16 at a position facing the lower top portion 13b1 of the elastic pressing member 13, and the protruding portion 20d faces the lower top portion 13b1.

  As shown in FIG. 3, the detecting means 16 includes a soft lower sheet 14a and an upper sheet 14b that are stacked via a spacing sheet (not shown), and resistors are provided on the opposing surfaces of the lower sheet 14a and the upper sheet 14b, respectively. Is provided. Both the lower sheet 14a and the upper sheet 14b are formed of a synthetic resin material such as PET (polyethylene terephthalate) resin having flexibility and insulation.

  As shown in FIGS. 3 and 4, the resistors of the lower sheet 14a are eight resistor members 16a formed in a radial pattern (individually, the resistor members 16a1, 16a2, 16a3, 16a4, 16a5, 16a6, 16a7, 16a8). Show.) The resistor of the upper sheet 14b is the counter electrode 16b. The eight resistance members 16a and the counter electrode 16b are supported so as to be able to contact and separate. The resistance member 16a is formed of a resistance material having a sufficiently higher specific resistance than the counter electrode 16b.

  Instead of the spacing sheet, an insulating resin film may be formed on one or both of the lower sheet 14a and the upper sheet 14b so as to ensure a space between the lower sheet 14a and the upper sheet 14b. Good.

  The resistance member 16a is formed of a carbon film or the like, and the counter electrode 16b is formed of a film having a lower electric resistance than the resistance member 16a, for example, a metal film such as silver, gold, or copper.

  As shown in FIG. 4, one end on the inner peripheral side of the resistance member 16 a is connected to each of the circular connection electrodes 16 c, and is divided and arranged radially in the circumferential direction of the concentric circles of the connection electrodes 16 c. In this embodiment, eight resistance members 16a1, 16a2, 16a3, 16a4, 16a5, 16a6, 16a7, and 16a8 are provided. Although the conductive connection is made, the connection electrode 16c may be provided on the outer peripheral side, and the end portions on the outer peripheral side of the respective resistance members 16a1 to 16a8 may be conductively connected.

  Conductive wire patterns made of silver, copper, or the like are wired at the outer peripheral ends of the resistance members 16a1 to 16a8, respectively, and a power source of a power supply device (not shown) is connected via a switching means (not shown) provided outside. It can be connected to the terminal (+ terminal). The connecting electrode 16c is connected to the ground terminal GND of the power supply device.

  In the case where the connecting electrode 16c is configured to electrically connect end portions on the outer peripheral side of the respective resistance members 16a1 to 16a8, the conductive wire pattern is connected to end portions on the inner peripheral side of the resistance members 16a1 to 16a8. The voltage may be applied by connecting the connecting electrode 16c to the + terminal and connecting each conductor pattern to the ground terminal GND, or vice versa. In other words, when the switching means is driven and the contacts are continuously switched at a predetermined cycle, between the radially outer end of each of the resistance members 16a1 to 16a8 and the other inner peripheral end. In addition, it is sufficient that the predetermined power supply voltage Vcc can be applied clockwise or counterclockwise at a constant cycle.

  The configuration of the detection means 16 is not limited to the above configuration. For example, the detection member 16 is not a stack of three sheets, but a resistance member formed on a single sheet. An elastic pressing member in which a low-resistance conductive member is formed on the resistance member may be opposed.

  As shown in FIGS. 2 and 3, the sheet substrate 14 is installed on a rigid base 15 formed of a highly rigid member such as metal or synthetic resin. The base 15 is provided with a switch 29 (see FIG. 4) for generating a click feeling at a position facing the central protrusion 20a, and a reversing switch 17 for generating a click feeling at a position facing the protrusion 20d. Is provided. The structure of the central switch 29 is the same as that of the inverting switch 17.

  The reversing switch 17 is provided between the base 15 and the detecting means 16 of the sheet substrate 14, and a metal dome-shaped reversing plate 17b is provided on a synthetic resin sheet 17a such as PET resin, and the reversing plate 17b. The peripheral edge portion 17b1 is fixed to the sheet 7a. Further, a conductive pattern 17c is formed on the surface of the sheet 17a at a position facing the inner center of the reversing plate 17b, and another conductive pattern 17d is connected to the peripheral edge portion 17b1 of the reversing plate 17b.

  As shown in FIG. 2, in the input device 10 of the present invention, the operation member 20 is inserted into the opening 18 a of the housing 18 in the Z1 direction from the Z2 side, and the base 15 is fixed to the support member 19 in the housing 18. ing. The operation member 20 is biased in the Z1 direction by the elastic pressing member 13, and the surface of the operation member 20 is protruded from the opening 18a of the housing 18 in the Z1 direction.

  Further, on the inner peripheral side of each elastic pressing member 13, a convex portion 13t protruding in the Z1 direction (upward direction) is integrally formed. Each convex portion 13t is inserted into a slit-like concave portion 20c formed on each lower surface 20b of the operating bodies 21 to 28, and the operating member 20 does not rotate around the central projection portion 20a as an axis. It regulates so that.

FIG. 3 shows an initial state in which the operation member 20 is not operated.
If the operation member 20 is pressed at an arbitrary operation point P, the operation member 20 is counterclockwise in FIG. 2 with the central protrusion 20a as a fulcrum, that is, one operation body 27 faces downward, The operating body 23 is tilted so as to face upward. At this time, as shown in FIG. 5, the lower surface 20 b on the operation body 27 side presses the upper edge portion 13 c of the elastic pressing member 13, so that the elastic pressing member 13 is elastically deformed.

  As shown in FIG. 5, when the elastic pressing member 13 is elastically deformed, the upper sheet 14 b and the counter electrode 16 b of the sheet substrate 14 are deformed in a convex shape toward the lower direction. Is brought into contact with the resistance member 16a7 provided at the position corresponding to.

  The switching means is driven at a predetermined cycle (frequency), and a predetermined power supply voltage Vcc is applied to the eight resistance members 16a1 to 16a8. The voltage of the counter electrode 16b is detected at a predetermined cycle by voltage detection means (not shown). The period (frequency) of detection of the counter electrode 16b may be the same as the period of the switching means, but is preferably at least shorter than the period of the switching means (high in frequency).

  When the voltage of the counter electrode 16b, that is, the potential of the contact point P0 is detected using the voltage detection means, the resistance value between the one end on the outer peripheral side of the resistance member 16a7 and the contact point P0, the contact point P0, and the connecting electrode 16c. The position of the contact point P0 on the resistance member 16a7 (the position in the radial direction) can be detected from the resistance ratio to the resistance value between the two. Therefore, it is possible to detect from the detection voltage the position in the radial direction of the operating point P corresponding to the contact point P0 and that the operating body 27 among the operating bodies 21 to 28 has been operated.

  In addition, even when the portion located in the inner direction (the connecting electrode 16c side) of the operating body 27 is pressed, the radial position of the pressed portion of the operating body 27 is detected in the same manner as described above. Even when an operating body other than the operating body 27 is pressed, the pressed operating body and the position in the radial direction can be specified in the same manner as described above.

Here, for example, a voltage value Vcc / 2 is half the power supply voltage Vcc applied to the resistor member 16a as a threshold V _th, the control unit (not shown), the voltage value at the contact point P0 and the threshold V _th Compare. For example, FIG. 6 shows a case where the operating bodies 21 to 28 are continuously pressed in the clockwise direction at a constant time interval Δt.

As shown in FIG. 6A, when the position of the operation point P is pressed as the outer peripheral side on each operation body, the voltage value output from each contact point P0 of the resistance members 16a1 to 16a8 is from the threshold value _Vth . Also grows. For this reason, it can be determined that the outer peripheral side of the operating bodies 21 to 28 has been pressed.

On the other hand, as shown in FIG. 6B, when a pressing operation is performed with the position of the contact point P0 as the inner peripheral side on each operating body, the voltage value output from each contact point P0 of the resistance members 16a1 to 16a8 is the threshold value. It becomes smaller than the value _Vth . For this reason, it can be determined that the inner peripheral side of the operating bodies 21 to 28 has been pressed.

  The control unit continuously detects the pressing operation on the operating bodies 21 to 28 at a predetermined sampling period, so that the operation on the operating bodies 21 to 28 can be obtained as a continuous analog amount.

In addition, for example, an outer portion where the voltage value at the contact point P0 is detected as a value larger than the portion where the threshold value _Vth is detected is continuously along the circumferential direction of a concentric circle centering on the connection electrode 16c. Suppose that it pressed. That is, the outer portion of the operating body 21 is first pressed, then the outer portion of the operating body 22 is pressed, the outer portion of the operating body 23 is further pressed, and so on. When the positions outside the operating bodies are sequentially pressed at a constant speed , the voltage values output from the contact points P0 of the resistance members 16a1 to 16a8 are shown as shown in FIG. 7B .

On the other hand, when the same operation is performed at an inner position where the voltage value at the contact point P0 is smaller than the threshold value _{Vth, the} voltage value output from each contact point P0 of each resistance member 16a1 to 16a8 is As shown in FIG. 7A .

That is, as shown in FIGS. 7A and 7B, when the outer peripheral side is operated and the inner peripheral side is operated in a state where the speed is substantially constant, the output pulse cycle is higher on the inner peripheral side. It can be seen that it is shorter than the outer peripheral side. That is, when the inner peripheral side is operated, an output with a higher operation speed can be obtained compared to when the outer peripheral side is operated.

When equipped with an input device 10 having the above-mentioned features to the mobile phone, when for example the inner portion of the operating member 20 is continuously pressed in the circumferential direction of the concentric circles, the display of the mobile phone an image or the like displayed on the part set to be scrolled in a predetermined direction at a faster rate, when the outer portion of the operating member 20 was continuously pressed in the circumferential direction of the concentric circles, the image or the like at a slower speed It can be set to scroll in a predetermined direction.

  In the present invention, it is preferable that a plurality of counter electrodes 16b are provided and one counter electrode 16b is disposed so as to face one resistance member 16a. With such an arrangement, when an arbitrary operating body is pressed and the counter electrode 16b provided below the operating body corresponding to the operating body is deformed downward, a plurality of resistors Of the member 16a, only the resistance member 16a facing the counter electrode 16b deformed downward is in contact with the counter electrode 16b. Therefore, at the same time as the counter electrode 16b provided below the operating body to be pressed, an operating body that should not be pressed in the vicinity of the operating body to be pressed, for example, below the adjacent operating body. It is possible to prevent the counter electrode 16b being pressed from being accidentally pressed.

  Further, in the present invention, as shown in FIG. 4, each resistance member 16 a preferably has a shape in which the width dimension gradually increases in the radial direction from the inner peripheral connection electrode 16 c toward the outer peripheral side. Here, FIG. 8 is a graph showing the relationship between the position in the length direction of each resistance member and the output voltage at that position, and the solid line in the figure gradually increases the width dimension of the resistance member as shown in FIG. In the case of the wide resistor a, the alternate long and short dash line indicates a case where the resistor member is a rectangular resistor (constant width resistor) b having a constant width dimension.

  The origin of the horizontal axis of the graph is the innermost peripheral side of the resistance member, and the direction of the horizontal axis indicates the outer peripheral direction of the resistance member.

When the threshold value _Vth is set to a voltage value Vcc / 2 which is ½ of the power supply voltage Vcc, the resistor b having a constant width has an inner peripheral side at the midpoint position L / 2 of the length L. The boundary with the outer peripheral side is set, and in the case of the wide resistor a, the boundary between the inner peripheral side and the outer peripheral side is set at a position L1 (0 <L1 <L / 2) inside the midpoint position L / 2. Is done. Therefore, in the wide resistor a, when the boundary between the inner peripheral side and the outer peripheral side is set at the midpoint position L / 2, the threshold value _Vth is set between the voltage value Vcc / 2 and the power supply voltage Vcc. The relatively high voltage level Va can be set, and the resolution on the inner peripheral side can be made wider than that on the outer peripheral side. For this reason, if the boundary between the inner peripheral side and the outer peripheral side is further set on the outer peripheral side than the midpoint position L / 2, even if the size (major axis) of the input device 10 is relatively small, The operation on the inner peripheral side can be facilitated. That is, when the boundary (threshold value) for discriminating between the inner peripheral side and the outer peripheral side is set to a position (outer peripheral position) outside the midpoint position L / 2, an operation area that functions as the inner peripheral side is set. In addition to being able to enlarge, it is possible to obtain a wider resolution, so that the operability on the inner peripheral side can be improved. In this case, the outer peripheral side operation area and the resolution are narrowed. However, since the outer peripheral side operation area is originally located outside the inner peripheral side, the operation on the outer peripheral side operation area is performed. There is no such thing as inferior to the inner circumference.

  In addition, in order to avoid an erroneous operation input by the operator, it is necessary to provide a dead zone region with a certain width near the boundary (threshold value) between the inner peripheral side and the outer peripheral side so as not to accept an operation. . As shown in FIG. 8, if the width dimension in the length direction of the dead zone region is W, the dead zone voltage width that cannot be used as the output voltage V for the dead zone ΔW is the dead zone voltage width in the case of the resistor b having a constant width. In contrast to ΔVb, in the case of the wide resistor a, the dead band voltage width ΔVa can be made narrower (ΔVb> ΔVa). For this reason, in the wide resistor a, the range that can be used as the output voltage V can be widened compared to the resistor b having a constant width, so that detection with a wide resolution and high accuracy is possible.

  In addition, when the resistance member 16a is formed by the resistor b having a constant width, the distance between the adjacent resistor b and the resistor b (the area of the opposing region or the opposing region is compared with the case where the resistor member 16a is formed by the wide resistor a. (Dimension) becomes wide. Therefore, the output signal of the input device 10 is formed with a long non-signal time period that is not output as a signal. That is, since the duty ratio tends to be small, it is difficult to supplement the operation between the adjacent constant width resistor b and the constant width resistor b. Further, in order to supplement the operation during this period, a separate identification unit or the like is required, and the configuration of the input device 10 is complicated. However, when the resistance member 16a is formed of the wide resistor a whose width is gradually increased as in the present invention, the area of the opposing region between the adjacent wide resistor a and the wide resistor a (or the opposite) Since the duty ratio of the output signal of the input device 10 is increased, it becomes easy to supplement the operation between the adjacent wide resistor a and the wide resistor a. For this reason, it becomes possible to provide the input device 10 with high detection accuracy.

  In the present invention, as shown by a dotted line in FIG. 3, for example, when a portion corresponding to the protruding portion 20 d of the operating body 27 is pressed, the protruding portion 20 d is pushed down, and the protruding portion 20 d is the lower top portion 13 b 1 of the elastic pressing member 13. Press. For this reason, the elastic pressing member 13 can be deformed in a balanced manner when the operating body 27 is pressed.

  Thereafter, the sheet substrate 14 is pressed by the elastic pressing member 13 according to the same principle as described above, and the central portion of the reversing plate 17b provided in the reversing switch 17 is deformed into a concave shape to generate a click feeling. Simultaneously with the click feeling, the inner surface of the reversing plate 17b connected to the conductive pattern 17d comes into contact with the surface of the conductive pattern 17c by the reversing operation, and the output of the reversing switch 17 is switched from off to on. That is, digital output is performed.

  The digital output as described above is performed in the same manner even when an operation body other than the operation body 27 is pressed.

  In this way, when the operator is given a click feeling, the operator can easily and accurately recognize that the reverse switch 17 has been pressed.

  Further, in the present invention, when the inverting switch 17 is provided, an analog output can be obtained on the detection means 16 side, and an on / off digital output can be obtained on the inverting switch 17 side. Thereby, for example, when the input device 10 of the present invention is mounted on a mobile phone, the scroll function can be operated by analog output, and operations such as selection and determination of menus and images by digital output. Can be performed.

  In the present invention, as described above, an analog output can be obtained by continuously pressing the inner part or the outer part of the plurality of operating bodies 21 to 28 in the circumferential direction of the concentric circle. A digital output can be obtained by pressing one operating body. In this way, in the present invention, the operation for obtaining the analog output and the operation for obtaining the digital output are clearly separated, so that the operator can reliably perform the operation for obtaining the desired output. And the operability of the input device 10 can be improved.
