Description

  The present invention relates to an operation panel in which a pointing operation and an input operation such as a character and a figure are performed by an input unit such as a finger or a position indicator, and an input device including the operation panel.

  As a conventional operation panel of this type, there is one described in Patent Document 1, for example. Japanese Patent Application Laid-Open No. 2004-228561 describes a coordinate detection apparatus that performs coordinate input to a computer as an external device.

  The coordinate detection apparatus described in Patent Document 1 is a cable that extends from a circuit board to the outside of the casing in order to electrically connect the circuit board, a casing that wraps the circuit board, and the circuit board and an external device. It has. In this coordinate detection device, a check pin guide hole is formed in a part of the housing, and an input / output signal to / from an external device is extracted from a portion of the circuit board corresponding to the check guide pin hole. A check terminal is provided.

JP-A-6-214700

  Usually, when drawing a figure or the like on paper using a writing instrument such as a pen, it may be difficult to draw depending on the direction of the line to be drawn or the direction of the paper. In that case, the paper is rotated to change the orientation of the paper so that it is easy to draw. However, the coordinate detection apparatus described in Patent Document 1 does not have a configuration for rotating the housing as when actually drawing on paper with a writing instrument. Therefore, when drawing a figure or the like, if the orientation of the casing is poor and it is difficult to draw, the body position is changed to a position where the user himself can easily draw with respect to the casing. As a result, the position of the body must be changed as needed depending on the direction of the line to be drawn.

  An object of the present invention is to provide an easy-to-use operation panel and input device that can easily rotate the casing in a user-friendly direction without changing the position of the body in consideration of the above-described problems. It is to provide.

And a rotation center member that is disposed inside the region surrounded by the plurality of leg members and abuts against the placement surface when an input operation of the input unit is performed. The friction coefficient for the mounting surface of the rotation center member is set to be larger than the friction coefficient for the mounting surfaces of a plurality of leg members, and the case can be rotated with the rotation center member as the rotation center when the input unit is input. It is characterized by comprising.

  The input device of the present invention includes an operation panel for inputting information, and an input unit for inputting information to the operation panel. The operation panel is as described above, and includes a housing having an input unit, and a plurality of members that are attached to the housing and are in contact with the placement surface and support the housing. A leg member, and a rotation center member that is disposed inside a region surrounded by the plurality of leg members in the housing and that abuts against the placement surface when an input operation is performed at the input unit. Yes. The friction coefficient for the mounting surface of the rotation center member is set to be larger than the friction coefficient for the mounting surfaces of a plurality of leg members, and the case can be rotated with the rotation center member as the rotation center when the input unit is input. It is characterized by being configured.

  According to the operation panel and the input device of the present invention, by providing the rotation center member that rotatably supports the casing, the casing can be easily rotated in a user-friendly direction. Ease can be improved.

  Embodiments for carrying out an operation panel and an input device of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the following embodiments.

FIG. 1 is a perspective view showing an input device, and FIGS. 2 to 13 are views showing an operation panel of the present invention.
As shown in FIG. 1, an input device 1 according to an embodiment of the present invention (hereinafter referred to as “this example”) inputs an operation panel 2 to which information is input, and inputs information to the operation panel 2. The pen-type position indicator 3 is provided. This pen-type position indicator 3 is merely a specific example of input means. The input device 1 is used as an input device for these external devices by connecting the operation panel 2 to an external device (not shown) such as a personal computer or PDA (Personal Digital Assistant) via a cable 10.

  The position indicator 3 of the input device 1 is for instructing the position to the operation panel 2 by an electromagnetic induction method. That is, the position indicator 3 has a resonance circuit that resonates with an electromagnetic wave having a specific frequency transmitted from the operation panel 2, and operates by transmitting a resonance signal detected by the resonance circuit to the operation panel 2. The position is instructed to the panel 2.

  The operation panel 2 of the input device 1 includes an input unit 4 that is a touch panel, a case 5 having a hollow thin rectangular parallelepiped shape having the input unit 4, and a rotation center member 6 that rotatably supports the case 5. The plurality of leg members 16a to 16d are configured.

  As will be described later with reference to FIG. 5, the housing 5 includes an upper case 7 having an opening 11 that exposes an input surface of the input unit 4, a lower case 8 superimposed on the upper case 7, and the upper case 7 and a frame 9 that partitions the space formed by the lower case 8 vertically.

FIG. 2 is a block diagram for explaining the configuration and operation of the operation panel.
As shown in FIG. 2, the input unit 4 has a thin flat plate shape, and includes an electromagnetic induction type position detection unit 105 and a display unit (not shown) disposed on the back of the position detection unit 105. Yes.

  The display unit is a display device having a horizontally-long rectangular flat plate shape having the same size as the position detection unit 105. An image similar to the image displayed on the display unit of the external device is displayed on the display unit. A liquid crystal display panel, an organic EL (Electroluminescence) panel, or other display monitor is applied to the display unit. A backlight panel is disposed as a light source on the back surface of the display unit. In addition, although the example which provided the display part as the input part 4 was demonstrated in this example, this display part itself is not essential for the input part 4. FIG.

Position detecting unit 105 has, for example, a forty loop coils _X 1 _{to X 40} of which is arranged in the X-axis direction, of the 40 present, which is arranged in the Y-axis direction and the loop coil _Y 1 _{to Y 40} ing. The loop coils X _{1 to} X ₄₀ and the loop coils Y _{1 to} Y ₄₀ are connected to a selection circuit 106 that selects each loop coil. In this embodiment, the number of loop coils is 40, but the present invention is not limited to this.

  The selection circuit 106 is connected to a transmission / reception switching circuit 107, and an amplifier 108 is connected to the reception side of the transmission / reception switching circuit 107. The amplifier 108 is connected to a detection circuit 109, and the detection circuit 109 is connected to a sample hold circuit 112 via a low-pass filter (LPF) 110. Further, the sample hold circuit 112 is connected to an analog / digital conversion circuit (AD conversion circuit) 113, and this analog / digital conversion circuit 113 is connected to a CPU (central processing unit) 114. The CPU 114 supplies control signals to the selection circuit 106, the sample hold circuit 112, the analog / digital conversion circuit 113, and the transmission / reception switching circuit 107 described above.

Further, the operation panel 2 is provided with an oscillator 116 that generates an alternating current signal having a frequency f ₀ and a current driver 117 that converts the alternating current signal into a current. The current driver 117 is provided on the transmission side of the transmission / reception switching circuit 107. It is connected. Namely, the contact of reception switching circuit 107 by a control signal supplied from the CPU114 is the switched to the transmission side, a magnetic field is generated from the loop coil _X 1 _{to X 40} and loop coils _Y 1 _{to Y 40} of the position detecting section 105.

When the position indicator 3 approaches the position detection unit 105, the resonance circuit built in the position indicator 3 resonates and an induced voltage is generated. Then, when the contact point of the transmission / reception switching circuit 107 is switched to the reception side by the control signal supplied from the CPU 114, the position detection unit 105 does not supply the magnetic field to the position indicator 3. As a result, a magnetic field is generated from the position detection coil built in the position indicator 3 by the induced voltage generated at the time of reception. The position detection unit 105 detects the position of the position indicator 3 by detecting the magnetic field generated by the position detection coil. As a result, the operation panel 3 detects the position indicated by the position indicator 3 from the selected positions of the loop coils X _{1 to} X ₄₀ and Y _{1 to} Y ₄₀ as XY coordinates.

  In this example, the example in which the electromagnetic induction method is applied as the coordinate detection method of the position detection unit 105 has been described. However, the present invention is not limited to this. For example, a capacitance method, a pressure-sensitive method, a light detection method, and other coordinate detection methods can be applied.

  Moreover, as shown in FIG. 1, the upper case 7 has comprised the thin container shape by which one surface was opened. The upper case 7 includes a rectangular opening 11 that exposes the input surface of the input unit 4, and two touch pad units 12 and 13 that are disposed on both the left and right sides of the opening 11. The input portion 4 described above is fitted into the opening portion 11. The two touch pad units 12 and 13 are provided with various operation buttons for setting the size of the drawing area, scrolling the screen, zooming in / out the screen, and the like. As shown in FIG. 4, a plurality of fixing portions 14 for fixing the lower case 8 (see FIGS. 3 and 5) and the frame 9 with fixing screws 18 are provided on the back side of the upper case 7. .

FIG. 3 is a view of the operation panel according to the embodiment of the present invention as seen from the back side.
As shown in FIG. 3, the lower case 8 has a thin lid shape and is overlaid so as to close the opening of the upper case 7. The lower case 8 is fixed to the upper case 7 with fixing screws 18. In addition, as a fixing method of the upper case 7 and the lower case 8, not only the fixing screw 18 but also an adhesive, welding, or other fixing methods can be used in order to strengthen the fixing. Four leg members 16 a, 16 b, 16 c, and 16 d that support the housing 5 in contact with the mounting surface G such as a desk are provided on the rear surface, which is the lower surface of the lower case 8.

  The four leg members 16a, 16b, 16c, and 16d have a substantially cylindrical shape, and are fixed to four corners on the back surface of the lower case 8 with an adhesive or the like. Note that the fixing method of the four leg members 16a to 16d to the lower case 8 is not limited to the adhesive, and other fixing methods such as screwing and fitting are also conceivable. The heights of the four leg members 16a to 16d are set to be substantially the same, and one end in the axial direction is located in the same plane. Thereby, when the operation panel 2 is placed on a desk or the like, it can be used without rattling. And as a material of these four leg members 16a-16d, a thing with a low friction coefficient with respect to the mounting surface G is good, for example, felt etc. are preferable. Further, an insertion hole 17 (see FIG. 6) through which the rotation center member 6 is inserted is provided in a substantially central portion of the lower case 8, that is, inside a region surrounded by the four leg members 16a to 16d.

  In this example, the number of leg members 16 is four, but the present invention is not limited to this. For example, in order to support the housing 5 in a balanced manner, at least three leg members may be provided, or five or more leg members may be provided. Furthermore, in this example, the shape of the leg member 16 is a columnar shape, but is not limited to this. For example, the shape of the leg member 16 is a prism shape, a truncated cone shape, or a truncated pyramid shape. Good.

  As the material of the upper case 7 and the lower case 8, engineering plastic is usually used, but metals such as stainless steel can be used in addition to the engineering plastic.

FIG. 4 is a view showing a state where the lower case is removed from the operation panel of this example. FIG. 5 is a cross-sectional view of the operation panel of this example cut in the longitudinal direction.
As shown in FIGS. 4 and 5, the frame 9 has a flat plate shape and is housed in the housing 5 so as to partition the space formed by the upper case 7 and the lower case 8 in the vertical direction. . The frame 9 covers the entire back surface of the input unit 4 via the spacer 19. The frame 9 is fixed to the upper case 7 by a fixing method such as screwing. Further, a recessed portion 21 that is recessed in a substantially rectangular shape is formed in a substantially central portion of the frame 9. The material of the frame 9 is generally a steel plate such as stainless steel, but may be a plastic plate such as engineering plastic in addition to the steel plate.

  Further, as shown in FIG. 5, a control board 15 on which the CPU 114 and the like are mounted is disposed on the back surface of the input unit 4. As shown in FIG. 4, a cable 10 is connected to the control board 15, and an input signal from the input unit 4 is transmitted from the cable 10 to an external device (not shown).

FIG. 6 is an enlarged view of the rotation center member and the elastic body of this example, and FIG. 7 is a perspective view thereof.
As shown in FIGS. 6 and 7, the recessed portion 21 is recessed toward the input portion 4 in a state where the frame 9 is fixed to the upper case 7. The recessed portion 21 is provided with two fixing portions 22a and 22b, and a leaf spring 24 showing a specific example of an elastic body is fixed to the two fixing portions 22a and 22b by two fixing screws 23a and 23b. The Thus, by fixing the leaf spring 24 to the recessed portion 21 that is recessed toward the upper case 7, it is possible to prevent the casing 5 from becoming thick due to the thickness of the leaf spring 24.

FIG. 8 is an exploded perspective view showing the attachment structure of the rotation center member 6 and the elastic body (leaf spring 24) of this example.
As shown in FIG. 8, the leaf spring 24 has a substantially rectangular shape, and has two fastening holes 25a and 25b on one side in the longitudinal direction and an engagement hole 26 on the other side in the longitudinal direction. . Two fixing screws 23 a and 23 b are screwed into the two fastening holes 25 a and 25 b, and are fixed to the two fixing portions 22 a and 22 b provided in the recessed portion 21. An engagement groove 28 of the rotation center member 6 described later is engaged with the engagement hole 26, and the rotation center member 6 is attached. In addition, although this example demonstrated the example which applied the leaf | plate spring as an elastic body, it is not limited to this. For example, other elastic members such as a coil spring and rubber may be used. Further, in this example, since the plate spring 24 having a thickness smaller than that of the coil spring or the like is used instead of a thick elastic body such as a coil spring or the like, the thickness of the housing 5 can be reduced. .

FIG. 9 is a view showing the rotation center member 6 used in this example.
As shown in FIGS. 9A to 9C, the rotation center member 6 has a cylindrical shape, and has an engagement groove 28 on the outer periphery of one end portion in the axial direction. The engagement groove 28 is a recess that is continuously recessed in the circumferential direction of the rotation center member 6. Further, the rotation center member 6 is provided with a contact portion 29 that comes into contact with the mounting surface G such as a desk, at the other end portion in the axial direction opposite to the engagement groove 28. The contact portion 29 has a spherical shape, and the center portion is the highest. Thereby, the contact portion 29 of the rotation center member 6 makes point contact with the placement surface G.

  In addition, although the example which formed the shape of the contact part 29 in the spherical shape was demonstrated in this example, it is not limited to this. For example, the shape of the contact portion 29 may be formed in a circular shape or a square shape, or may be formed in a truncated cone shape or a truncated pyramid shape so as to be in surface contact with the mounting surface G.

  In addition, an axial hole 30 is provided at one end of the rotation center member 6 in the axial direction over a predetermined length from the end surface in the axial direction. The axial hole 30 reduces the rigidity of one end of the rotating center member 6 in the axial direction so that it can be easily elastically deformed. As a result, the end of the rotation center member 6 on the axial hole 30 side is easily elastically deformed, so that the engagement groove 28 can be easily engaged with the engagement hole 26 of the leaf spring 24. Further, the outer flange portion 31 and the inner flange portion 32 are formed by forming the engaging groove 28 on the outer periphery of one end portion in the axial direction of the rotation center member 6. The diameter of the inner flange portion 32 is set larger than the diameter of the outer flange portion 31. In this example, an example in which the shape of the rotation center member 6 is a cylindrical shape has been described. However, the present invention is not limited to this, and for example, the shape of the rotation center member 6 may be a prism shape. is there.

Furthermore, as shown in FIG. 10, the friction coefficient μ _{1 with} respect to the placement surface G of the rotation center member 6 is set to be larger than the friction coefficient μ _{2 with} respect to the placement surface G of the four leg members 16 a to 16 d ( μ ₁ > 4 × μ ₂ ). Therefore, the material of the rotation center member 6 is preferably a material having a larger coefficient of friction with respect to the placement surface G than the material of the leg member 16, and examples thereof include silicon rubber. Alternatively, the surface of the contact portion 29 of the rotation center member 6 may be coated with a material having a large friction coefficient or roughened to increase the friction coefficient with respect to the mounting surface G from the leg member 16. .

Here, when a force smaller than the friction coefficient μ ₁ of the rotation center member 6 and larger than the friction coefficient μ ₂ of the four leg members 16 a to 16 d is applied from the side surface of the housing 5, the friction force of the contact portion 29 is large. Therefore, the rotation center member 6 does not move, but the four leg members 16a to 16d having a small frictional force slide on the placement surface G. As a result, as shown in FIG. 1 and FIG. 10, the housing 5 rotates with the rotation center member 6 having a large friction coefficient as a rotation axis, substantially parallel to the input surface of the input unit 4.

  As described above, the casing 5 rotates approximately horizontally with the input surface of the input unit 4 about the rotation center member 6 as a rotation axis, so that the orientation of the casing 5 can be changed to a direction that is easy for the user to use. . Thereby, a user-friendly operation panel can be provided, and the working efficiency can be improved by rotating the housing 5 in a direction that is easy for the user to use.

  Further, as shown in FIGS. 7 and 8, the rotation center member 6 is attached to the leaf spring 24 by engaging the engagement groove 28 with the engagement hole 26 of the leaf spring 24. As shown in FIG. 6, when the lower case 8 is overlapped with the upper case 7, the contact portion 29 of the rotation center member 6 protrudes from the insertion hole 17 of the lower case 8 to the back side of the housing 5. . At this time, the rotation center member 6 is located inside the region surrounded by the four leg members 16 a to 16 d on the back surface of the lower case 8. And when the housing | casing 5 is mounted in the mounting surface G, in order to prevent the backlash of the housing | casing 5, the protrusion height from the lower case 8 of the rotation center member 6 is 4 leg members 16a-16d. It is preferable that the height is set substantially the same as the height in the axial direction.

  However, it is difficult for the lower case 8 to manufacture all products completely flat in the manufacturing process, and variations easily occur between products. Therefore, if the rotation center member 6 is simply provided in the lower case 8, it will not be substantially the same as the height of the four leg members 16a to 16d. Therefore, if the rotation center member 6 protrudes, rattling occurs, and if the rotation center member 6 is retracted, the contact portion 29 does not come into contact with the placement surface G, which may be useless.

  Therefore, in this embodiment, as described above, the rotation center member 6 is attached to the frame 9 via the elastic leaf spring 24. Therefore, as shown in FIG. 11, even when the four leg members 16a to 16d and the rotation center member 6 are not the same height, when the housing 5 is placed on the placement surface G such as a desk, the housing The leaf spring 24 is elastically deformed by its own weight. As a result, the protruding height of the rotation center member 6 from the lower case 8 and the heights of the four leg members 16a to 16d in the axial direction can be made the same. That is, the tip of the contact portion 29 of the rotation center member 6 and one end of the four leg members 16a to 16d can be arranged in the same plane. Thereby, it is possible to prevent or suppress rattling that occurs when the housing 5 is placed on the placement surface G, and the input surface of the input unit 4 can be kept substantially horizontal.

  In the present embodiment, the example in which the engagement groove 28 is engaged with the engagement hole 26 of the leaf spring 24 as the fixing means of the rotation center member 6 has been described. However, the present invention is not limited to this. FIG. 12 shows another embodiment of the rotation center member according to the operation panel 2 of the present invention. The rotation center member 61 according to this example has a cylindrical shape, and has a fixing hole 62 into which the fixing screw 63 is screwed. The leaf spring 24 has a screw hole 64 into which the fixing screw 63 is screwed instead of the engagement hole 24. The rotation center member 61 is fixed to the leaf spring 24 with a fixing screw 63. Also by such a rotation center member 61, the same effect as the rotation center member 6 mentioned above can be acquired.

  In the present embodiment, the example in which the rotation center member 6 is attached to the frame 9 via the leaf spring 24, which is an elastic body, has been described. However, the present invention is not limited to this. As shown in FIG. 13, the rotation center member 6 may be directly attached to the lower case 8 by engaging the engagement groove 28 of the rotation center member 6 with the insertion hole 17 of the lower case 8. In FIG. 13, the rotation center member 6 is directly attached to the lower case 8 without using an elastic body. However, the rotation center member 6 is attached to the lower case 8 through an elastic body as in the present embodiment. Of course, it may be attached.

  The operation panel 2 having such a configuration can be assembled as follows, for example. First, the input unit 4 is fitted into the opening 11 of the upper case 7 and fixed by a fixing method such as screwing. Then, as shown in FIG. 4, the frame 9 is arranged via a spacer 19 so as to cover the back surface of the input unit 4 attached to the upper case 7, and is fixed to the upper case 7 with a fixing screw 18.

  Next, as shown in FIG. 7, the leaf spring 24 is fixed to the fixing portions 22a and 22b provided in the recessed portion 21 of the frame 9 by screwing with fixing screws 23a and 23b. Next, the outer flange portion 31 side of the rotation center member 6, that is, the side opposite to the contact portion 29 is caused to face the engagement hole 26 of the leaf spring 24 fixed to the frame 9. Then, the engagement groove 26 of the rotation center member 6 is engaged with the engagement hole 26 of the leaf spring 24, and the rotation center member 6 is attached to the leaf spring 24. At this time, since the axial hole 30 is provided in the rotation center member 6, the rotation center member 6 is elastically deformed by the axial hole 30, so that the engagement groove 28 is easily engaged with the engagement hole 26. Can be combined.

  Next, the rotation center member 6 attached to the leaf spring 24 is inserted into the insertion hole 17, and the lower case 8 is overlapped with the upper case 7 so as to close the opening of the upper case 7. At this time, four leg members 16a to 16d are previously attached to the four corners of the back surface of the lower case 8 by a fixing method such as an adhesive. Then, the lower case 8 is fixed to the upper case 7 with a fixing screw 18. Thereby, the assembly of the operation panel 2 is completed.

  As described above, according to the operation panel of the present invention, the rotation center member having a larger coefficient of friction with respect to the placement surface than the leg member is provided in the casing. And this rotation center member is arrange | positioned inside the area | region enclosed by several leg members. Therefore, if a force smaller than the coefficient of friction of the rotation center member and larger than the coefficient of friction of the leg member is applied to the housing, the rotation center member does not move, but the leg member having a small coefficient of friction slides on the mounting surface. . Thereby, a housing | casing rotates centering on a rotation center member. As a result, when drawing a figure or the like using a pen-type input means, if the orientation of the housing is poor and difficult to draw, the housing can be easily rotated in a direction that is easy for the user to draw. Therefore, since the housing can be easily rotated in a direction that is easy for the user to draw without changing the position of the user's body, an easy-to-use operation panel can be provided.

  Furthermore, the rotation center member was attached to the housing via an elastic body. Therefore, even when the height of the rotation center member and the height of the leg member are not equal, the elastic body is elastically deformed when the casing is placed on the placement surface. As a result, the height of the rotation center member and the leg member can be made equal. Thereby, while being able to keep the input surface of an input part horizontal, the rattling of a housing | casing can be prevented or suppressed. Moreover, since the shape of the contact part which contacts the mounting surface in the rotation center member is a spherical shape, the contact part makes point contact with the mounting surface. Thereby, the housing can be easily rotated.

  The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention described in the claims. For example, in the above-described embodiment, an example in which a pen-type position indicator is used as a specific example of the input unit has been described. However, when the coordinate detection method of the position detection unit of the input unit is a pressure-sensitive method, The user's finger can be applied. In addition, although the case and the input unit have been described as a quadrangle, the shape of the case and the input unit may be a circle, a triangle, a hexagon, an octagon, or the like.
