JP 2001-202198 A

  By the way, various electronic devices such as portable information terminals and AV devices have been miniaturized, and the market strongly demands simplification and thinning of the structure of the mounted switch. The slide operation switch of Patent Document 1 has a mechanical configuration including many parts. Specifically, a resistance circuit formed on the surface of the substrate, a case fixed to the substrate, a sliding operation body mounted on the case, and linear movement in the X direction and the Y direction with the slide operation of the operation body It is equipped with a set of upper and lower moving bodies, a set of contacts attached to each side of the moving body and in sliding contact with the resistance circuit on the substrate surface, a set of coil springs that automatically return the moving body to the origin position, etc. The number of parts is large and the structure is complicated. In addition, a three-dimensional component is incorporated, the bulk of the entire switch is large, and it is difficult to reduce the thickness of the switch. In addition, the spring constant gradually decreases due to the expansion and contraction of the coil spring accompanying the sliding operation. Then, since the urging force to the moving body is weakened, the moving body may not automatically return to the origin position.

  The present invention has been made against the background of the prior art as described above. That is, an object of the present invention is to provide a thin slide operation switch having a simple structure.

  In order to achieve the above object, the present invention is configured as follows.

  That is, the present invention provides a slide operation switch including a fixed member and an operation member that can move laterally along the surface direction of the fixed member, and provides a slide electrode on either the fixed member or the operation member. An X-coordinate variable resistor and a Y-coordinate variable resistor whose resistance values change according to a change in a contact position with the sliding electrode due to a lateral movement of the operation member are provided on any one of the other members. Provide a slide operation switch.

  In the present invention, a sliding electrode is provided on one of the fixed member and the operating member, and the resistance value changes according to a change in the contact position with the sliding electrode due to the lateral movement of the operating member on either one of the above. An X coordinate variable resistor and a Y coordinate variable resistor are provided. Then, a change in physical value detected by both variable resistors, for example, an output voltage value associated with a lateral movement operation of the operation member, is detected, a lateral movement position is calculated, and coordinate input is performed. As described above, the fixed member, the operation member, the sliding electrode attached to these members, and the two types of variable resistors are used, and the number of parts is small and a simple structure can be realized. Further, since the side movement position is input by the sliding contact between the sliding electrode having a planar configuration and the variable resistor, the thickness can be reduced.

  In the slide operation switch according to the present invention, the fixing member and the operation member are made of an insulating sheet.

  According to the present invention, since the fixing member and the operation member are formed of the insulating sheet, it is possible to realize a reduction in thickness and weight. As the insulating sheet, an elastic sheet or a resin film made of a rubber-like elastic body such as a thermosetting elastomer such as silicone rubber or a thermoplastic elastomer can be used.

  The present invention is such that the variable resistor is rectangular in plan view with respect to the slide operation switch.

  According to the present invention, since the variable resistor is formed in a rectangular shape in plan view, the resistance value of the variable resistor changes in proportion to the amount of movement of the contact point between the variable resistor and the sliding electrode. . Therefore, linear coordinate input accompanying the movement amount of the operation member can be easily controlled.

  The present invention is such that the variable resistor has an arc shape in plan view with respect to the slide operation switch.

  According to the present invention, since the variable resistor is formed in an arc shape in plan view, when the sliding contact point between the variable resistor and the sliding electrode approaches the end of the variable resistor, the resistance of the variable resistor The amount of change in value changes in a curved or analog manner. Therefore, it is possible to easily control coordinate input so that the speed of coordinate movement is accelerated according to the movement amount of the operation member.

  In the present invention, the slide operation switch is provided with an elastic sheet for returning the origin of the operation member that moves laterally to the operation member.

  According to the present invention, since the elastic member for returning the origin of the operation member that moves sideways is provided on the operation member, the repulsive force of the deformed elastic sheet can be obtained simply by releasing the operation of the operation member moved sideways. Thus, the operating member can be automatically returned to the origin position.

  In the present invention, the slide operation switch is provided with a contact switch that is input by a pressing operation of the operation member below the operation member at the origin position.

  In the present invention, since the contact switch that is input by the pressing operation of the operating member is provided below the operating member at the origin position, the coordinate input by the lateral movement operation and the input by the pressing operation are performed by the operating member. Can do. Specifically, it is possible to perform an operation of selecting an item on the screen by a side movement operation and determining the selection of the item by a pressing operation of the operation member. In this case, the contact switch can be provided on a surface of the fixed member facing the operation member. In addition, the contact switch can be provided on the substrate by providing a substrate on the back side of the fixing member.

  In the slide operation switch according to the present invention, the X-coordinate variable resistor and the Y-coordinate variable resistor are formed of a linear body and are provided at an outer position of the contact switch.

  In the present invention, since the X-coordinate variable resistor and the Y-coordinate variable resistor are formed in a linear body and provided at the outer position of the contact switch, the contact for performing a definite input or the like by pressing the operation member The switch can be arranged below the operation member at the origin position.

  The concrete form of the sliding electrode by the above this invention can be comprised as follows, for example.

  The first is to form the sliding electrodes as two straight lines that are in contact with each other in an orthogonal state with respect to the X coordinate variable resistor and the Y coordinate variable resistor. According to this, when comparing the case where the linear sliding electrode is in contact with each variable resistor and the case where the linear sliding electrode is orthogonal and in contact with each variable resistor, The contact width of the sliding electrode with respect to the body is larger for the former and smaller for the latter. Therefore, according to the first embodiment, the effective movement length of the sliding electrode can be increased for each variable resistor, and the range of coordinate input can be set large.

  Secondly, the sliding electrode is formed into a straight line extending outward from two different points on the circumference of the circular portion and the circular portion of the circular portion in plan view. According to this, a contact switch can be provided in the annular part of a sliding electrode, or the press area | region can be provided.

  Moreover, the above-mentioned this invention can be comprised further as follows.

  The slide operation switch of the present invention can be configured to include a sliding body having a small sliding friction of the operation member between the fixed member and the operation member. According to this, when the operating member is moved laterally, the frictional resistance with the sliding body is small and smooth movement is possible. Therefore, the operator can perform a lateral movement operation with a light force.

  About the slide operation switch of the said invention, at least any one of a fixing member or an operation member can be comprised as what consists of a low friction body. According to this, when the operation member is moved sideways, the frictional resistance with the fixed member is small and a smooth movement can be performed. Therefore, the operator can perform a lateral movement operation with a light force. The low friction body is made of a material having a small friction coefficient or has a low surface gloss. Examples of the material having a small friction coefficient include fluorine resins, silicone resins, polyacetal resins, and high molecular weight polyethylene resins. Those having a low surface gloss are, for example, those having a glossiness of 60 degrees and 14 or less.

  According to the slide operation switch of the present invention, it is composed of a fixed member, an operation member, a sliding electrode, and two types of variable resistors, and has a small number of parts and realizes multi-directional input by a slide operation with a simple configuration. can do. Further, since the input of the lateral movement position is performed by the sliding contact between the sliding electrode having a planar configuration and the variable resistor, the thickness can be reduced. Furthermore, since there are few components and manufacture is easy, an inexpensive slide operation switch is realizable.

  Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. In addition, about the structure which is common in each embodiment, the same code | symbol is attached | subjected and duplication description is abbreviate | omitted.

First Embodiment [FIGS. 1 to 5]
The slide operation switch 1 according to the first embodiment includes a fixing member 2 and an operation member 3. The fixed member 2 is provided with an X coordinate variable resistor 4 and a Y coordinate variable resistor 5, and the operation member 3 is provided with a sliding electrode 6.

  The slide operation switch 1 is obtained by superposing the fixed member 2 and the operation member 3 so that the X coordinate variable resistor 4 and the Y coordinate variable resistor 5 and the slide electrode 6 face each other. The operation member 3 moves sideways on the surface of the fixed member 2 within a range where the sliding electrode 6 is always in contact with both the variable resistors 4 and 5.

  The fixing member 2 is formed of an insulating sheet such as a polyethylene terephthalate resin film, a polycarbonate resin film, a polybutylene terephthalate resin film, and these aloe resin films. On the surface of the fixing member 2, a rectangular / linear X-coordinate variable resistor 4 in a plan view along the X-axis direction and a rectangular / linear Y-coordinate variable resistor in a plan view along the Y-axis direction are provided. A body 5 is provided. Each wiring is a separate wiring, and wirings 7 and 8 are connected to the X coordinate variable resistor 4, and wirings 9 and 10 are connected to the Y coordinate variable resistor 5. The X-coordinate variable resistor 4 and the Y-coordinate variable resistor 5 as described above can be formed by printing resistor ink containing carbon black on the fixed member 2. The wirings 7 to 10 can be formed by screen-printing conductive ink containing carbon black. The conductive ink is obtained by adding a large amount of a conductive material such as metal or carbon black to a polymer serving as a binder, and the resistor ink has a smaller amount of conductive material added than the conductive ink. .

  The operation member 3 is formed of an insulating sheet similar to the fixing member 2. A sliding electrode 6 is provided on the back surface of the operation member 3. The sliding electrode 6 is an L-shaped unit consisting of two straight lines orthogonal to each other in plan view. The electrode 6 can be formed by screen printing a conductive ink containing a silver filler.

  Here, a method of position detection accompanying the lateral movement of the operation member 3 will be described with an example.

  When detecting the X coordinate, as shown in FIG. 3, a power source is connected to the wires 7 and 8 to generate a voltage distribution in the longitudinal direction of the X coordinate variable resistor 4. Thereby, the voltage at the contact position with the sliding electrode 6 in the longitudinal direction of the X coordinate variable resistor 4 is uniquely determined, and this voltage signal passes through the sliding electrode 6 and the Y coordinate variable resistor 5, It is detected through the wirings 9 and 10. When detecting the Y coordinate, a power source is connected to the wirings 9 and 10 to generate a voltage distribution in the longitudinal direction of the Y coordinate variable resistor 5. Thereby, the voltage at the contact position with the sliding electrode 6 in the longitudinal direction of the Y coordinate variable resistor 5 is uniquely determined, and this voltage signal passes through the sliding electrode 6 and the X coordinate variable resistor 4, It is detected through the wirings 7 and 8. In this way, each movement direction and each movement amount (X coordinate, Y coordinate) in the X direction and the Y direction are detected.

The principle of voltage detection and position detection of both variable resistors 5 and 6 will be further described by taking the X coordinate variable resistor 4 as an example. This description is the same for the Y-coordinate variable resistor 5. As shown in FIG. 4, the X coordinate variable resistor 4 is connected to the ground line G from the power supply voltage VCC through the X coordinate variable resistor 4. The magnitude of the output voltage V ₀ of the X coordinate variable resistor 4 varies depending on the position of the sliding electrode 6 in contact with the X coordinate variable resistor 4. Using this amount of change, the position of lateral movement is detected and coordinates are input. FIG. 5 shows the measurement results for the movement amount (slide amount) of the X coordinate and the output voltage value in this embodiment. In this case, the output voltage value changes linearly with respect to the movement amount. For this reason, the coordinate input corresponding to the movement amount can be accurately controlled.

  Next, functions and effects of this embodiment will be described.

  The slide operation switch 1 is composed of a fixed member 2, an operation member 3, an X coordinate variable resistor 4, a Y coordinate variable resistor 5, and a slide electrode 6, and has a simple configuration with a small number of parts. Multi-directional input by slide operation can be realized.

  Furthermore, in this embodiment, the fixed member 2 made of an insulating sheet is provided with an X coordinate variable resistor 4 and a Y coordinate variable resistor 5 having a planar configuration, and the operation member 3 made of an insulating sheet is planar. The sliding electrode 6 having the configuration is provided. For this reason, it becomes thin and lightweight, and further thinness and lightness of the portable device can be realized.

  The X coordinate variable resistor 4 and the Y coordinate variable resistor 5 are formed in a rectangular linear body in plan view. For this reason, the resistance values of the variable resistors 4 and 5 change proportionally with the amount of movement of the sliding contact between the variable resistors 4 and 5 and the sliding electrode 6 (FIG. 5). Therefore, linear coordinate input associated with the amount of movement of the operation member can be easily controlled.

  The sliding electrode 6 is an integrated body composed of two straight lines orthogonal to each other in plan view. For this reason, the sliding electrode 6 does not contact the X-coordinate variable resistor 4 and the Y-coordinate variable resistor 5 obliquely, but contacts in an orthogonal state where the contact width is the smallest, so that both the variable resistors The effective movement length of the sliding electrode 6 in the bodies 4 and 5 can be increased. Therefore, the coordinate input range can be set large.

Modification of First Embodiment [FIGS. 6 to 8]
Finally, a modification of the first embodiment will be described.

  In the first modification, as shown in FIG. 6, the X coordinate variable resistor 11 and the Y coordinate variable resistor 12 are formed in a rectangular planar body in plan view. For this reason, a contact area becomes large and the sliding electrode 6 can be made to contact reliably. Moreover, since the contact area is large, the sliding electrode 6 can be made small, so that there is an advantage that the operation member 3 can be miniaturized. In the first modification, variable resistor electrodes 11a and 12a that are slightly longer than the short sides are provided on the short sides of the variable resistors 11 and 12 connected to the wiring. For this reason, a voltage can be reliably applied also to the corner portions of the rectangular and planar variable resistors 11 and 12.

  In the second modification, as shown in FIG. 7, the X coordinate variable resistor 13 and the Y coordinate variable resistor 14 are formed in an arc shape in plan view. According to this, when the sliding contact points between the variable resistors 13 and 14 and the sliding electrode 6 (not shown) approach the end portions of the variable resistors 13 and 14, the variable resistors 13 and 14 The amount of change in resistance value changes in a curve. This phenomenon will be described using the X-coordinate variable resistor 13 as an example with reference to FIG. The same applies to the Y coordinate variable resistor 14. FIG. 8 is an enlarged view from the center portion to the right end portion of the X coordinate variable resistor 13. The amount of movement when the sliding electrode 6 is linearly moved in the X direction at a constant speed is equally divided into five sections (a to e) and indicated by arrows. The arc length of each section of the X-coordinate variable resistor 13 gradually increases as it moves from the central portion a to the right end portion e. That is, the amount of change in the resistance value in each section gradually increases as it moves from the central portion a to the right end portion e. Therefore, coordinate input can be performed such that the speed of coordinate movement increases as the operating member moves away from the origin position.

Second Embodiment [FIGS. 9 to 11]
The slide operation switch 15 of the second embodiment is different from the slide operation switch 1 of the first embodiment in that the configuration of the operation member 16, the spacer 17, and the substrate 18 are provided. The operating member 16 is provided with a sliding electrode 19, and the substrate 18 is provided with a contact switch 20. The configuration of the fixing member 2 is the same as that in the first embodiment.

  The slide operation switch 15 is obtained by superposing the fixing member 2 and the operation member 16 with the spacer 17 interposed therebetween so that the X-coordinate variable resistor 4 and the Y-coordinate variable resistor 5 are opposed to the slide electrode 19. It is. The operation member 16 moves sideways on the surface of the fixed member 2 within a range where the sliding electrode 19 is always in contact with both the variable resistors 4 and 5. A substrate 18 provided with a contact switch 20 is installed on the surface opposite to the surface facing the operation member 16 of the fixing member 2.

  The operation member 16 is made of silicone rubber. The operation member 16 is formed with an annular thin portion 16b extending outward at the upper end of a cylindrical base portion 16a, and a leg portion slightly thicker than the thin portion 16b on the outer side of the thin portion 16b. 16c is provided. A spacer 17 is fixed to the back surface of the leg portion 16c. A columnar protrusion 16d is provided on the surface of the base portion 16a. The protrusion 16d is coaxial with the base portion 16a and has a smaller diameter than the diameter of the base portion 16a. A cylindrical pusher portion 16e is provided on the back surface of the base portion 16a toward the substrate 18. The pusher portion 16e is formed coaxially with the base portion 16a and smaller in diameter than the diameter of the base portion 16a. The tip of the pusher portion 16 e is in contact with the surface of the fixing member 2. Further, a sliding electrode 19 formed on the annular resin film 21 is provided so as to surround the pusher portion 16e. The sliding electrode 19 is formed by a circular annular portion 19a in plan view and linear portions 19b and 19c extending outward from two different points on the circumference of the annular portion 19a. The sliding electrode 19 can be formed by metal vapor deposition on the resin film 21.

  The spacer 17 is made of hard resin and is formed in a square ring shape. The spacer 17 is formed so that the X-coordinate variable resistor 4 and the Y-coordinate variable resistor 5 and the sliding electrode 19 are in contact with each other.

  The board | substrate 18 is formed in the flat plate with resin. On the surface of the substrate 18, a contact switch 20 using a metal disc spring is provided below the origin position of the base portion 16 a of the operation member 16.

  Next, operations and effects of the second embodiment will be described, but only those unique to the second embodiment will be described, and description common to the first embodiment will be omitted.

  The operation member 16 is provided with an annular thin portion 16b. Since the thin portion 16b is made of silicone rubber, when the operation of the base portion 16a moved laterally is released, the base portion 16a can be automatically returned to the origin position by the repulsive force of the deformed thin portion 16b.

  The slide operation switch 15 is provided with a contact switch 20 below the base portion 16a at the origin position. The contact switch 20 is pressed and input by the pusher portion 16e in accordance with the pressing operation of the protrusion 16d. For this reason, both the coordinate input by the side movement operation and the input by the pressing operation can be performed.

  In addition, since the X coordinate variable resistor 4 and the Y coordinate variable resistor 5 are formed in a linear linear body and provided at the outer position of the contact switch 20, the pressing operation of the contact switch 20 at the origin position is performed. Even if it repeats, it is hard to apply a pressing load to both variable resistors 4 and 5, and it can make it difficult to damage both variable resistors 4 and 5.

  Since the sliding electrode 19 is formed of a circular annular portion 19a and linear portions 19b and 19c in plan view, the pusher portion 16e and the contact switch 20 can be provided inside the annular portion 19a. . Therefore, even if the pressing operation of the contact switch 20 is repeated, it is difficult to apply a pressing load to the sliding electrode 19 and it is difficult to break.

  The operation member 16 is formed of silicone rubber which is a low friction body. For this reason, when the base portion 16a is moved laterally, the frictional resistance between the tip of the pusher portion 16e and the surface of the fixing member 2 is small, and a smooth movement is possible. Therefore, the operator can perform a lateral movement operation with a light force. In this embodiment, the operation member 16 is made of silicone rubber having both characteristics of elasticity and low friction. However, the operation member 16 is formed using a rubber-like elastic body other than this, and the fixing member 2 is used. The same effect can be realized even if a layer made of a low friction body is provided at the tip of the operating member 16 in contact with.

Modification of Second Embodiment [FIG. 12]
Finally, a modification of the second embodiment will be described.

  In the modification of the second embodiment, the leg portion 16c is thick, and the X-coordinate variable resistor 4 and the Y-coordinate variable resistor 5 and the sliding electrode 19 are in contact with each other and fixed to the fixing member 2. is there. According to this, the structure can be further simplified by the abolition of use of the spacer 17.

Third Embodiment [FIGS. 13 to 15]
The slide operation switch 22 of the third embodiment is different from the slide operation switch 1 of the first embodiment in that the configuration of the operation member 23, the operation body 24, the slide body 25, and the substrate 18 are provided. The operating member 23 is provided with a sliding electrode 19, and the substrate 18 is provided with a contact switch 20 similar to that of the second embodiment. The remaining configuration is the same as in the first embodiment.

  The slide operation switch 22 is configured such that the fixed member 2 and the operation member 23 are overlapped with the slide body 25 sandwiched so that the X-coordinate variable resistor 4 and the Y-coordinate variable resistor 5 face the slide electrode 19. Is. The operation member 23 moves sideways on the surface of the fixed member 2 within a range where the sliding electrode 19 is always in contact with both the variable resistors 4 and 5. An operation body 24 provided with a thin portion 24a is fixed to the surface of the operation member 23 opposite to the surface facing the fixing member 2. A substrate 18 provided with a contact switch 20 is installed on the surface of the fixing member 2 opposite to the surface facing the operation member 23.

  The operation member 23 is formed of an insulating sheet similar to the fixing member 2. The operation member 23 is formed with a hole 23a penetrating the wall thickness, and a pusher portion 24b of the operation body 24 is inserted into the hole 23a. On the surface of the operation member 23, a base portion 24c of the operation body 24 is fixed to an edge portion of the hole 23a. On the back surface of the operation member 23, a sliding electrode 19 is provided on the outer periphery of the hole 23a. The sliding electrode 19 can be formed by screen printing a conductive ink containing a silver filler.

  The operation body 24 is made of silicone rubber. The operating body 24 is formed with a thin portion 24a extending outward on the side surface of the cylindrical base portion 24c. The thin portion 24 a is fixed to a member (not shown) having an outer edge portion around the slide operation switch 21. A cylindrical pusher portion 24b is provided on the back surface of the base portion 24c toward the substrate 18, and the pusher portion 24b is coaxial with the base portion 24c and has a smaller diameter than the diameter of the base portion 24c. The tip of the pusher portion 24 b penetrates into the hole 23 a of the operation member 23 and is in contact with the surface of the fixing member 2.

  The sliding body 25 is provided as an insulating layer containing spherical particles. The sliding body 25 is formed by screen printing on the surface of the fixing member 2, and the surface has a fine irregular surface with a slight difference in height of about 2 μm to 3 μm with slightly exposed spherical particles.

  Next, operations and effects of the third embodiment will be described, but only those unique to the third embodiment will be described, and descriptions common to the first embodiment will be omitted.

  The operating body 24 is provided with a thin portion 24a. Since the thin portion 24a is made of silicone rubber, when the operation of the base portion 24c moved laterally and the operation member 23 fixed thereto are released, the base portion 24c and the operation member 23 are moved to the original position by the repulsive force of the deformed thin portion 24a. Can be automatically restored.

  The slide operation switch 21 is provided with a contact switch 20 below the base 24c at the origin position. The contact switch 20 is pressed and input by the pusher portion 24b in accordance with the pressing operation of the base portion 24c. For this reason, both the coordinate input by the side movement operation and the input by the pressing operation can be performed.

  In addition, since the X coordinate variable resistor 4 and the Y coordinate variable resistor 5 are formed in a linear linear body and provided at the outer position of the contact switch 20, the pressing operation of the contact switch 20 at the origin position is performed. Even if it repeats, it is hard to apply a pressing load to both variable resistors 4 and 5, and it can make it difficult to damage both variable resistors 4 and 5.

  Since the sliding electrode 19 is formed by the circular annular portion 19a and the linear portions 19b and 19c in plan view, the pusher portion 23b and the contact switch 20 can be provided inside the annular portion 19a. . Therefore, even if the pressing operation of the contact switch 20 is repeated, it is difficult to apply a pressing load to the sliding electrode 19 and it is difficult to break.

  The sliding body 25 reduces sliding friction with the operation member 23 by a fine uneven surface. For this reason, when the operation member 23 is moved sideways, the frictional resistance with the sliding body 25 is small and a smooth movement is possible. Therefore, the operator can perform a lateral movement operation with a light force.

Modification of Third Embodiment [FIG. 16]
Finally, a modification of the third embodiment will be described.

  In the modification of the third embodiment, the contact switch 20 is arranged on the surface of the fixing member 2. The contact switch 20 is disposed at the origin position of the operation member 23. Accordingly, the pusher portion is formed shorter than the pusher portion 24b. According to this, the board | substrate 18 can be eliminated and it can reduce in thickness.
