Description

本発明は操作部材の移動量に応じて電気抵抗(出力電圧)を変化させる可変抵抗器に関する。   The present invention relates to a variable resistor that changes electric resistance (output voltage) in accordance with the amount of movement of an operation member.

従来の可変抵抗器において、摺動子は抵抗回路部上を摺動する。この抵抗回路部は直列抵抗回路を形成しているものであり、その直列抵抗回路は導体部と抵抗体部とが摺動子の軌道上に交互に配列されたものである。導体部は、銀の層がカーボンでの層で覆われた2層構造であり、抵抗体部は導体部のカーボンの層と連続したカーボンのみの1層から成っている。   In the conventional variable resistor, the slider slides on the resistance circuit portion. This resistance circuit portion forms a series resistance circuit, and the series resistance circuit is configured such that conductor portions and resistor portions are alternately arranged on the track of the slider. The conductor part has a two-layer structure in which a silver layer is covered with a carbon layer, and the resistor part consists of a single carbon layer continuous with the carbon layer of the conductor part.

摺動子が抵抗体部上を移動するとき、可変抵抗器の出力電圧は変動する。摺動子が導体部上を移動するとき、出力電圧は一定に維持される。したがって、例えば、第1〜第4抵抗体部が直列接続され、第1,第2抵抗体部間に第1導体部が位置し、第2,第3抵抗体部間に第2導体部が位置し、第3,第4抵抗体部の間に第3導体部が位置した抵抗回路部について、この抵抗回路部に対する摺動子の位置と出力電圧との関係を考えると、出力電圧の特性は次のようになる。   When the slider moves on the resistor portion, the output voltage of the variable resistor varies. When the slider moves on the conductor portion, the output voltage is kept constant. Therefore, for example, the first to fourth resistor parts are connected in series, the first conductor part is located between the first and second resistor parts, and the second conductor part is located between the second and third resistor parts. Considering the relationship between the position of the slider with respect to the resistance circuit portion and the output voltage for the resistance circuit portion where the third conductor portion is located between the third and fourth resistor portions, the characteristics of the output voltage Is as follows.

摺動子が第1抵抗体部から第3導体部まで摺動する際、まず、摺動子は第1抵抗体部の一端から他端まで移動する。この間、出力電圧は0段階から第1段階まで漸次上昇する。次に、摺動子が第1抵抗体部を通過して第1導体部の一端に達し、この第1導体部の他端まで移動する間、出力電圧は第1段階に維持される。次に、摺動子が第1導体部を通過して第2抵抗体部の一端に達し、この第2抵抗体部の他端まで移動する間、出力電圧は第1段階から第2段階まで漸次上昇する。次に、摺動子が第2導体部の一端に達し、この第2導体部の他端まで移動する間、出力電圧は第2段階に維持される。次に、摺動子が第2導体部を通過して第3抵抗体部の一端に達し、この第3抵抗体部の他端まで移動する間、第2段階から第3段階まで漸次上昇する。次に、摺動子が第3抵抗体部を通過して第3導体部の一端に達し、この第3導体部の他端まで移動する間、出力電圧は第3段階に維持される。   When the slider slides from the first resistor portion to the third conductor portion, first, the slider moves from one end to the other end of the first resistor portion. During this time, the output voltage gradually increases from the zero stage to the first stage. Next, while the slider passes through the first resistor portion, reaches one end of the first conductor portion, and moves to the other end of the first conductor portion, the output voltage is maintained at the first stage. Next, while the slider passes through the first conductor portion and reaches one end of the second resistor portion and moves to the other end of the second resistor portion, the output voltage is changed from the first stage to the second stage. Gradually rises. Next, while the slider reaches one end of the second conductor portion and moves to the other end of the second conductor portion, the output voltage is maintained at the second stage. Next, while the slider passes through the second conductor portion and reaches one end of the third resistor portion and moves to the other end of the third resistor portion, the slider gradually rises from the second stage to the third stage. . Next, while the slider passes through the third resistor portion and reaches one end of the third conductor portion and moves to the other end of the third conductor portion, the output voltage is maintained at the third stage.

特開平9−193646JP-A-9-193646

前述した従来の可変抵抗器は、第1〜第3段階の出力電圧をそれぞれ摺動子の位置に関係なく一定に維持するための領域として第1〜第3導体部を有するが、それら第1〜第3段階以外の値の電圧、すなわち0段階と第1段階との間の高さ電圧、第1段階と第2段階の間の高さの電圧、第2段階と第3段階との間の高さの電圧(以下これらの電圧を「中間出力電圧」という)も、出力電圧として生起させる。   The conventional variable resistor described above has first to third conductor portions as regions for maintaining the output voltages of the first to third stages constant regardless of the position of the slider. ~ Voltage other than the third stage, that is, the high voltage between the zero stage and the first stage, the high voltage between the first stage and the second stage, between the second stage and the third stage Voltage (hereinafter referred to as “intermediate output voltage”) is also generated as an output voltage.

ここで、例えば、第1〜第3段階の出力電圧を電気機器の制御のための指令信号として用い、中間出力電圧を不要な出力電圧として扱うことを考えた場合、可変抵抗器の出力電圧が第1〜第3段階のいずれであるかどうかの判定を行う必要がある。この判定では、第1段階の出力電圧と、第1段階に近い電圧値ではあるが第1段階よりも低くい中間出力電圧との違い、および、第1段階の出力電圧と、第1段階に近い電圧値ではあるが第1段階よりも高い中間出力電圧との違いを判定する精度、すなわち、第1段階の出力電圧なのかそうでないのか判定の確実性が要求される。第2,第3段階についても同じく、その判定の確実性が要求される。   Here, for example, when the output voltage of the first to third stages is used as a command signal for controlling the electric equipment and the intermediate output voltage is considered as an unnecessary output voltage, the output voltage of the variable resistor is It is necessary to determine whether it is any of the first to third stages. In this determination, the difference between the output voltage of the first stage and the intermediate output voltage that is close to the first stage but lower than the first stage, and the output voltage of the first stage and the first stage The accuracy of determining the difference from the intermediate output voltage that is a close voltage value but higher than the first stage, that is, the certainty of whether the output voltage is the first stage or not is required. Similarly, the certainty of the determination is required for the second and third stages.

本発明は前述の事情を考慮してなされたものであり、その目的は、摺動子の移動量の連続した変化に対し、段階的、かつ、断続的に異なる高さの出力電圧を生起させることができる可変抵抗器を提供することにある。   The present invention has been made in view of the above-described circumstances, and its purpose is to generate output voltages of different heights stepwise and intermittently with respect to continuous changes in the amount of movement of the slider. It is to provide a variable resistor that can.

本発明は前述の目的を達成するために次のように構成されている。   The present invention is configured as follows to achieve the above-described object.

〔1〕 本発明は、複数の抵抗体部と複数の導体部とを有して前記抵抗体部と前記導体部とが交互に接続された抵抗回路部と、摺動子とを備え、前記摺動子が複数の前記導体部のうちのいずれかに選択的に接触することにより出力電圧が段階的に変化する可変抵抗器であって、前記摺動子の軌道上において前記導体部が絶縁体部に挟まれて位置することを特徴とする。 [1] The present invention includes a resistor circuit portion having a plurality of resistor portions and a plurality of conductor portions, the resistor portions and the conductor portions being alternately connected, and a slider, A variable resistor in which an output voltage changes stepwise when a slider selectively contacts any one of the plurality of conductor portions, and the conductor portion is insulated on a track of the slider. It is characterized by being sandwiched between body parts.

この「〔1〕」に記載の本発明において、摺動子は抵抗回路部上で複数の導体部間を摺動する際、絶縁体部と導体部に交互に接触する。導体部と抵抗体部は交互に接続されているので、摺動体が複数の導体部間で移動を行えば、出力電圧は段階的に増減することになる。また、摺動子は導体部に接触する前後に必ず絶縁体部を通過し、この通過の間は摺動子と抵抗回路部は電気的に切断された状態になるので、すなわち可変抵抗器がオフ状態になるので、摺動子の移動量が連続的に変化する一方で出力電圧は断続する。このように「〔1〕」に記載の本発明によれば、摺動子の移動量の連続した変化に対し、段階的、かつ、断続的に異なる高さの出力電圧を生起させることができる。   In the present invention described in “[1]”, when the slider slides between the plurality of conductor portions on the resistance circuit portion, the slider alternately contacts the insulator portion and the conductor portion. Since the conductor portions and the resistor portions are alternately connected, if the sliding body moves between the plurality of conductor portions, the output voltage increases or decreases stepwise. Also, the slider always passes through the insulator part before and after contacting the conductor part, and during this passage, the slider and the resistance circuit part are in an electrically disconnected state, that is, the variable resistor is Since it is in the OFF state, the output voltage is intermittent while the moving amount of the slider continuously changes. As described above, according to the present invention described in “[1]”, output voltages having different heights can be generated stepwise and intermittently in response to a continuous change in the moving amount of the slider. .

〔2〕 本発明は「〔1〕」に記載の発明において、前記摺動子の摺動方向において前記抵抗体部は前記導体部を挟んで位置し、前記絶縁体部のそれぞれは前記摺動子の軌道上に前記抵抗体部のそれぞれが露出しないよう、前記抵抗体部のそれぞれを前記摺動子の軌道側から覆って位置することを特徴とする。 [2] In the present invention according to [1], in the sliding direction of the slider, the resistor portion is located across the conductor portion, and each of the insulator portions is the sliding member. Each of the resistor parts is positioned so as to be covered from the track side of the slider so that the resistor parts are not exposed on the track of the child.

〔3〕 本発明は「〔1〕」に記載の発明において、前記抵抗体部は前記摺動子の軌道外に配列されたことを特徴とする。 [3] The present invention is the invention described in “[1]”, wherein the resistor portion is arranged outside the track of the slider.

〔4〕 本発明は「〔1〕」または「〔3〕」に記載の発明において、前記摺動子の軌道を含む平面上に、前記抵抗体部の列と前記導体部の列とが平行して位置し、前記導体部の列のみが前記摺動子の軌道上に位置することを特徴とする。 [4] In the present invention according to “[1]” or “[3]”, the row of the resistor portions and the row of the conductor portions are parallel to each other on a plane including the track of the slider. And only the row of the conductor portions is located on the track of the slider.

「〔4〕」に記載の発明によれば、摺動子の摺動方向において隣り合った抵抗体部の間隔寸法によって、同方向における導体部の寸法が制限されず、すなわちその間隔寸法よりも導体部の寸法を大きく設定でき、摺動子の摺動方向における導体部の寸法の自由度を、「〔2〕」に記載の発明よりも大きくすることができる。   According to the invention described in “[4]”, the size of the conductor portion in the same direction is not limited by the interval size of the resistor portions adjacent in the sliding direction of the slider, that is, more than the interval size. The size of the conductor portion can be set large, and the degree of freedom of the size of the conductor portion in the sliding direction of the slider can be made larger than that of the invention described in “[2]”.

本発明によれば、前記述したように、摺動子の移動量の連続した変化に対し、段階的、かつ、断続的に異なる高さの出力電圧を生起させることができる。これにより、出力電圧が各段階のうちのいずれに該当するものであるかの判定の確実性が向上し、電気機器の制御に利用する場合における可変抵抗器の扱い安さの向上に貢献できる。   According to the present invention, as described above, output voltages having different heights can be generated stepwise and intermittently with respect to a continuous change in the moving amount of the slider. This improves the certainty of determining which of the stages the output voltage corresponds to, and contributes to improving the handling ease of the variable resistor when used for controlling an electrical device.

[First Embodiment]
A first embodiment will be described with reference to FIGS. FIG. 1 is a sectional view of a variable resistor according to a first embodiment of the present invention. FIG. 2 is a top view of a resistance circuit unit provided in the variable resistor shown in FIG. 3 is a cross-sectional view taken along the line III-III in FIG. FIG. 4 is a characteristic diagram of the output voltage obtained by the resistance circuit unit shown in FIGS.

図1に示すように、第1実施形態に係る可変抵抗器1は、この可変抵抗器1全体の基礎となる基板2を備えている。この基板2にはカバー部材5が取り付けられている。このカバー部材5は基板2に対向して位置する上板部5aを有する。この上板部5aには長孔5bが形成されている。この長孔5bに基板2側から操作部材6が挿通されている。この操作部材6は長孔5bの長手方向(矢印S方向)にスライド可能である。   As shown in FIG. 1, the variable resistor 1 according to the first embodiment includes a substrate 2 that is the basis of the entire variable resistor 1. A cover member 5 is attached to the substrate 2. The cover member 5 has an upper plate portion 5 a located facing the substrate 2. A long hole 5b is formed in the upper plate portion 5a. The operation member 6 is inserted into the long hole 5b from the substrate 2 side. The operation member 6 is slidable in the longitudinal direction (arrow S direction) of the long hole 5b.

操作部材6は、カバー部材5の上板部5aと基板2との間において基板2と平行に広がった鍔部6aを有する。この鍔部6aには、摺動子7が基板2の方向に突出して設けられている。摺動子7は片持ち梁状に形成されていて、その可撓性により基板2に常時弾性的に押し付けられている。摺動子7の先端部は、図示してないが、二股に分岐して後述の抵抗回路部3に接触する第1摺動部と、後述の集電パターン10に接触する第2摺動部を成している。   The operation member 6 includes a flange portion 6 a that extends in parallel with the substrate 2 between the upper plate portion 5 a of the cover member 5 and the substrate 2. A slider 7 is provided on the flange 6 a so as to protrude in the direction of the substrate 2. The slider 7 is formed in a cantilever shape and is always elastically pressed against the substrate 2 due to its flexibility. Although not shown, the tip of the slider 7 is bifurcated to come into contact with a resistance circuit portion 3 described later and a second sliding portion contacted with a current collecting pattern 10 described later. Is made.

図2に示すように、抵抗回路部3は摺動子7の摺動方向に沿って延びて位置する。この抵抗回路部3は直列抵抗回路を形成している。この直列抵抗回路は、複数の抵抗体部、すなわち第1抵抗体部11、第2抵抗体部12、第3抵抗体部13および第4抵抗体部14(以下、これらをまとめて「第1抵抗体部11等」という)と、複数の導体部、すなわち第1導体部21、第2導体部22および第3導体部23(以下、これらをまとめて「第1導体部21等」という)とを有する。摺動子7の摺動方向において、第1抵抗体部11と第2抵抗体部12間には第1導体部21が位置し、第2抵抗体部12と第3抵抗体部13の間には第2導体部22が位置し、第3抵抗体部13と第4抵抗体部14の間には第3導体部23が位置する。   As shown in FIG. 2, the resistance circuit portion 3 is positioned so as to extend along the sliding direction of the slider 7. The resistance circuit unit 3 forms a series resistance circuit. The series resistor circuit includes a plurality of resistor parts, that is, a first resistor part 11, a second resistor part 12, a third resistor part 13, and a fourth resistor part 14 (hereinafter referred to as “first Resistor section 11 etc.) and a plurality of conductor sections, that is, first conductor section 21, second conductor section 22 and third conductor section 23 (hereinafter collectively referred to as "first conductor section 21 etc.") And have. In the sliding direction of the slider 7, the first conductor portion 21 is located between the first resistor portion 11 and the second resistor portion 12, and between the second resistor portion 12 and the third resistor portion 13. The second conductor portion 22 is located in the second conductor portion 23, and the third conductor portion 23 is located between the third resistor portion 13 and the fourth resistor portion 14.

第1導体部21等は、図3に示すように、基板本体2aにプリントされた銀の層と、この銀の層を覆ってプリントされたカーボンの層との2層構造である。第1抵抗体部11等は第1導体部21等のカーボンの層と連続したカーボンのみの1層から成っている。   As shown in FIG. 3, the first conductor portion 21 or the like has a two-layer structure of a silver layer printed on the substrate body 2a and a carbon layer printed covering the silver layer. The first resistor portion 11 and the like are formed of a single layer of only carbon that is continuous with the carbon layer of the first conductor portion 21 and the like.

摺動子7の第2摺動部の軌道9上には、集電パターン10がプリント成形により設けられている。集電パターン10は抵抗回路部3の第1導体部21等と同じく、銀の層がカーボンでの層で覆われた構造である。   A current collecting pattern 10 is provided on the track 9 of the second sliding portion of the slider 7 by printing. The current collection pattern 10 has a structure in which a silver layer is covered with a layer of carbon, like the first conductor portion 21 and the like of the resistance circuit portion 3.

特に第1実施形態においては、抵抗回路部3が、第1抵抗体部11等の抵抗体部と同数の絶縁体部、すなわち第1絶縁体部31、第2絶縁体部32、第3絶縁体部33および第4絶縁体部34(以下、これらをまとめて「第1絶縁体部41等」という)を有する。これらの第1絶縁体部31等はいずれも絶縁性の樹脂の層から成っている。第1絶縁体部31等は、第1抵抗体部11等がそれぞれ摺動子7の第1摺動部の軌道8上に露出しないよう、その軌道8側から第1抵抗体部11等のそれぞれを覆って位置する。つまり、第1摺動部の軌道8において第1導体部21等の導体部は、第1絶縁体部31等のそれぞれの絶縁体部に挟まれて位置する。具体的には、軌道8において第1導体部21の第2導体部22側とは反対側の領域には第1抵抗体部11を覆った第1絶縁体部31が設けられていて、第1導体部21と第2導体部22の間の領域は第2抵抗体部12を覆った第2絶縁体部32から成っている。同様に、軌道8において第2導体部22と第3導体部23の間の領域は第3抵抗体部13を覆った第3絶縁体部33から成っていて、第3導体部23の第2導体部22側とは反対側の領域には第4抵抗体部14を覆った第4絶縁体部34が設けられている。これにより、摺動子7の第1摺動部は、軌道8から分かるように、第1絶縁体部31上、第1導体部21上、第2絶縁体部32上、第2導体部22上、第3絶縁体部33上、第3導体部23上、第4絶縁体部34上の順に、絶縁体部上と導体部上とを交互に摺動するようになっている。   In particular, in the first embodiment, the resistance circuit unit 3 has the same number of insulators as the resistor parts such as the first resistor part 11, that is, the first insulator part 31, the second insulator part 32, and the third insulator. It has a body part 33 and a fourth insulator part 34 (hereinafter collectively referred to as “first insulator part 41 etc.”). Each of these first insulator portions 31 and the like is made of an insulating resin layer. The first insulator portion 31 and the like are arranged such as the first resistor portion 11 and the like from the track 8 side so that the first resistor portion 11 and the like are not exposed on the track 8 of the first slide portion of the slider 7. It is located over each other. That is, the conductor portion such as the first conductor portion 21 is positioned between the respective insulator portions such as the first insulator portion 31 in the track 8 of the first sliding portion. Specifically, a first insulator portion 31 that covers the first resistor portion 11 is provided in a region of the track 8 opposite to the second conductor portion 22 side of the first conductor portion 21. A region between the first conductor portion 21 and the second conductor portion 22 includes a second insulator portion 32 that covers the second resistor portion 12. Similarly, the region between the second conductor portion 22 and the third conductor portion 23 in the track 8 is composed of a third insulator portion 33 that covers the third resistor portion 13. A fourth insulator portion 34 that covers the fourth resistor portion 14 is provided in a region opposite to the conductor portion 22 side. Thereby, as can be seen from the track 8, the first sliding portion of the slider 7 is on the first insulator portion 31, on the first conductor portion 21, on the second insulator portion 32, and on the second conductor portion 22. On the third insulator part 33, on the third conductor part 23, and on the fourth insulator part 34, the insulator part and the conductor part are alternately slid in this order.

このように構成された可変抵抗器1における、摺動子7の抵抗回路部3に対する接触位置と出力電圧の関係について説明する。   The relationship between the contact position of the slider 7 with respect to the resistance circuit unit 3 and the output voltage in the variable resistor 1 configured as described above will be described.

図2において摺動子7が矢印S方向に第1抵抗体部11から第3導体部23まで摺動する間、摺動子7の第1摺動部は、第1抵抗体部11上、第1導体部21上、第2抵抗体部12上、第2導体部22上、第3抵抗体部13上、第3導体部23上の順に摺動する。この間、摺動子7の第2摺動部は第1摺接部と平行して集電パターン10上を摺動する。つまり、摺動子7は第2摺動部において集電パターン10に常時接触した状態で、第1摺動部において第1抵抗体部11、第1導体部21、第2抵抗体部12、第2導体部22、第3抵抗体部13および第3導体部23に対し、この順番で摺動する。   In FIG. 2, while the slider 7 slides from the first resistor portion 11 to the third conductor portion 23 in the arrow S direction, the first sliding portion of the slider 7 is on the first resistor portion 11. It slides on the first conductor part 21, the second resistor part 12, the second conductor part 22, the third resistor part 13, and the third conductor part 23 in this order. During this time, the second sliding portion of the slider 7 slides on the current collection pattern 10 in parallel with the first sliding contact portion. That is, the slider 7 is always in contact with the current collecting pattern 10 at the second sliding portion, and the first resistor portion 11, the first conductor portion 21, the second resistor portion 12, The second conductor part 22, the third resistor part 13 and the third conductor part 23 slide in this order.

その順番での摺動の間、まず摺動子は第1絶縁体部31の一端(図2における右端)から他端まで移動する。この移動の間(図4の領域Z1)において常に、摺動子7と抵抗回路部3は第1絶縁体部31により電気的に切断された状態になる。このため、可変抵抗器1がオフ状態に維持される。この状態において、第1絶縁体部31の電気抵抗値は無限大なので、出力電圧は0Vに維持される。   During sliding in that order, the slider first moves from one end (right end in FIG. 2) of the first insulator portion 31 to the other end. During this movement (region Z1 in FIG. 4), the slider 7 and the resistance circuit portion 3 are always electrically disconnected by the first insulator portion 31. For this reason, the variable resistor 1 is maintained in the off state. In this state, since the electrical resistance value of the first insulator portion 31 is infinite, the output voltage is maintained at 0V.

次に、摺動子7は第1絶縁体部31を通過し、これと同時に第1導体部21の一端に接触し、これにより可変抵抗器1はオンする。その後、摺動子7が第1導体部21の他端まで移動する間(図4の領域D1)、出力電圧は第1段階L1に維持される。   Next, the slider 7 passes through the first insulator portion 31 and simultaneously contacts one end of the first conductor portion 21, whereby the variable resistor 1 is turned on. Thereafter, while the slider 7 moves to the other end of the first conductor portion 21 (region D1 in FIG. 4), the output voltage is maintained at the first stage L1.

Thereafter, while the slider 7 moves to the other end of the second insulator portion 32 (region Z2 in FIG. 4), the variable resistor 1 is maintained in the off state (output voltage is 0 V) as in the case of the region Z1. Is done.

次に、摺動子7は第2絶縁体部32を通過し、これと同時に第2導体部22の一端に接触し、これにより可変抵抗器1はオンする。その後、摺動子7が第2導体部22の他端まで移動する間(図4の領域D2)、出力電圧は第1段階L1よりも高い第2段階L2に維持される。   Next, the slider 7 passes through the second insulator portion 32 and simultaneously contacts one end of the second conductor portion 22, thereby turning on the variable resistor 1. Thereafter, while the slider 7 moves to the other end of the second conductor portion 22 (region D2 in FIG. 4), the output voltage is maintained at the second stage L2 higher than the first stage L1.

なお、図4において、2点差線で示した特性線は、摺動子7が第1抵抗体部11等上を直接摺動した場合、すなわち、第1抵抗体部11等が第1絶縁体部31等に覆われていない、前述した従来の可変抵抗器における出力電圧の特性を示している。   In FIG. 4, a characteristic line indicated by a two-point difference line indicates that the slider 7 is slid directly on the first resistor part 11 or the like, that is, the first resistor part 11 or the like is the first insulator. The characteristic of the output voltage in the conventional variable resistor mentioned above which is not covered by the part 31 grade | etc., Is shown.

第1実施形態によれば次の効果を得られる。   According to the first embodiment, the following effects can be obtained.

第1実施形態において、摺動子7は抵抗回路部3上で第1導体部21等のうちの複数の導体部間で摺動する際、導体部と絶縁体部(第1絶縁体部31等のうちのいずれか)とに交互に接触する。導体部と抵抗体部は交互に接続されているので、摺動子7が複数の導体部間で移動を行えば、出力電圧は図4で示したように段階的に増減することになる。また、摺動子7は各導体部に接触する前後に必ず絶縁体部を通過し、この通過の間は摺動子7と抵抗回路部3は電気的に切断された状態になるので、すなわち可変抵抗器1がオフ状態になるので、摺動子7の移動量が連続して変化する一方で出力電圧は断続する。要するに、第1実施形態に係る可変抵抗器1によれば、摺動子7の移動量の連続した変化に対し、段階的、かつ、断続的に異なる高さの出力電圧を生起させることができる。したがって、出力電圧が各段階のうちのいずれに該当するものであるかの判定の確実性は向上する。   In the first embodiment, when the slider 7 slides between the plurality of conductor portions of the first conductor portion 21 and the like on the resistance circuit portion 3, the conductor portion and the insulator portion (first insulator portion 31). Etc.) alternately. Since the conductor portions and the resistor portions are alternately connected, if the slider 7 moves between the plurality of conductor portions, the output voltage increases or decreases stepwise as shown in FIG. Also, the slider 7 always passes through the insulator part before and after contacting each conductor part, and during this passage, the slider 7 and the resistance circuit part 3 are in an electrically disconnected state, that is, Since the variable resistor 1 is turned off, the amount of movement of the slider 7 continuously changes while the output voltage is intermittent. In short, according to the variable resistor 1 according to the first embodiment, output voltages having different heights can be generated stepwise and intermittently with respect to a continuous change in the moving amount of the slider 7. . Therefore, the certainty of determining which of the stages the output voltage corresponds to is improved.

なお、前述の第1実施形態に係る可変抵抗器1は、操作部材6が直線的にスライド操作されるものであり、これに対応して抵抗回路部3が直線状に形成されていたが、本発明はこれに限定されるものではなく、例えば、二輪車用シフトペダルセンサとしての可変抵抗器のように操作部材が回転操作されるものであって、抵抗回路部3に相当する抵抗回路部が操作部材の回転中心線周りに円弧状に形成されたものであってもよい。この場合、シフトペダルのブレが生じても所定の出力段階を確実に維持できるので、出力安定性に寄与する。   In the variable resistor 1 according to the first embodiment described above, the operation member 6 is linearly slid, and the resistance circuit unit 3 is formed linearly corresponding to this, The present invention is not limited to this. For example, the operating member is rotated like a variable resistor as a shift pedal sensor for a motorcycle, and a resistance circuit unit corresponding to the resistance circuit unit 3 is provided. It may be formed in an arc shape around the rotation center line of the operation member. In this case, a predetermined output stage can be reliably maintained even if shift pedal blur occurs, which contributes to output stability.

[Second Embodiment]
A second embodiment will be described with reference to FIGS. FIG. 5 is a top view of a resistance circuit unit provided in a variable resistor according to the second embodiment of the present invention. 6 is a cross-sectional view taken along the line VI-VI in FIG. FIG. 7 is a characteristic diagram of an output voltage obtained by the resistance circuit unit shown in FIGS. In FIG. 5, the same reference numerals as those shown in FIG. 2 are used for the elements equivalent to those shown in FIG.

第2実施形態に係る可変抵抗器は、第1実施形態とは異なる抵抗回路部40を備えている。この抵抗回路部40以外の構成については、第2実施形態に係る可変抵抗器は第1実施形態に係る可変抵抗器1と同様である。   The variable resistor according to the second embodiment includes a resistance circuit unit 40 different from the first embodiment. Regarding the configuration other than the resistor circuit section 40, the variable resistor according to the second embodiment is the same as the variable resistor 1 according to the first embodiment.

抵抗回路部40において、第1抵抗体部11、第2抵抗体部12、第3抵抗体部13および第4抵抗体部14は、摺動子7の軌道8を含む平面上に、すなわち、基板本体2aの上面に、
第1抵抗体部11等の列と第1導体部21等の列とが平行して位置する。そして、第1導体部21等の列のみが摺動子7の軌道8上に位置する。
In the resistance circuit unit 40, the first resistor unit 11, the second resistor unit 12, the third resistor unit 13 and the fourth resistor unit 14 are on a plane including the track 8 of the slider 7, that is, On the upper surface of the substrate body 2a,
A row of the first resistor portion 11 and the like and a row of the first conductor portion 21 and the like are positioned in parallel. Only the rows of the first conductor portions 21 and the like are located on the track 8 of the slider 7.

基板2の表面は、耐摩耗性かつ絶縁性の樹脂材(例えばフェノール系インク)でコーティングされている。第1導体部21等の導体部はそれぞれ第1摺動部の軌道8において、その耐摩耗性かつ絶縁性の樹脂材からなる絶縁体部に挟まれて位置する。つまり、第1導体部21の第2導体部22側とは反対側の領域、第1導体部21と第2導体部22の間の領域、第2導体部22と第3導体部23の間の領域、および、第3導体部23の第2導体部22側とは反対側の領域のそれぞれにおいて、耐摩耗性かつ絶縁性の樹脂材は、第1絶縁体部41、第2絶縁体部42、第3絶縁体部43、第4絶縁体部44を成している。これにより、摺動子7の第1摺動部は、軌道8を見て分かるように、第1絶縁体部41上、第1導体部21上、第2絶縁体部42上、第2導体部22上、第3絶縁体部43上、第3導体部23上、第4絶縁体部44上の順に、絶縁体部上と導体部上とを交互に摺動するようになっている。   The surface of the substrate 2 is coated with a wear-resistant and insulating resin material (for example, phenol-based ink). The conductor parts such as the first conductor part 21 are positioned on the track 8 of the first sliding part, sandwiched between the insulating parts made of the wear-resistant and insulating resin material. That is, a region of the first conductor portion 21 opposite to the second conductor portion 22 side, a region between the first conductor portion 21 and the second conductor portion 22, and between the second conductor portion 22 and the third conductor portion 23. In each of the region and the region of the third conductor portion 23 opposite to the second conductor portion 22 side, the wear-resistant and insulating resin material is the first insulator portion 41, the second insulator portion. 42, a third insulator portion 43, and a fourth insulator portion 44 are formed. Thereby, as can be seen from the track 8, the first sliding portion of the slider 7 can be seen on the first insulator portion 41, on the first conductor portion 21, on the second insulator portion 42, and on the second conductor. On the part 22, on the third insulator part 43, on the third conductor part 23, and on the fourth insulator part 44, the insulator part and the conductor part are slid alternately.

図7に示すように、第2実施形態に係る可変抵抗器によっても第1実施形態と同様の出力電圧が得られる。図7において、領域Zaは摺動子7が第1絶縁体部41上にあるときの出力電圧を示し、領域Zbは摺動子7が第2絶縁体部42上にあるときの出力電圧を示し、領域Zcは摺動子7が第3絶縁体部43にあるときの出力電圧を示す。また、領域Daは摺動子7が第1導体部21にあるときの出力電圧を示し、領域Dbは摺動子7が第2導体部22にあるときの出力電圧を示し、領域Dcは摺動子7が第3導体部23にあるときの出力電圧を示す。   As shown in FIG. 7, the output voltage similar to that of the first embodiment can be obtained also by the variable resistor according to the second embodiment. In FIG. 7, a region Za shows an output voltage when the slider 7 is on the first insulator portion 41, and a region Zb shows an output voltage when the slider 7 is on the second insulator portion 42. Region Zc shows the output voltage when the slider 7 is in the third insulator portion 43. The area Da shows the output voltage when the slider 7 is on the first conductor portion 21, the area Db shows the output voltage when the slider 7 is on the second conductor portion 22, and the area Dc shows the slide voltage. The output voltage when the moving element 7 is in the third conductor portion 23 is shown.

第2実施形態によれば次の効果を得られる。   According to the second embodiment, the following effects can be obtained.

第2実施形態において、摺動子7は抵抗回路部40上で第1導体部21等のすべての間またはいくつかの間を摺動する際、導体部と絶縁体部(第1絶縁体部41等のうちのいずれか)とに交互に接触する。導体部と抵抗体部は交互に接続されているので、摺動子7が複数の導体部間で移動を行えば、出力電圧は図7で示したように段階的に増減することになる。また、摺動子7は導体部に接触する前後に必ず絶縁体部を通過し、この通過の間は摺動子7と抵抗回路部40は電気的に切断された状態になるので、すなわち可変抵抗器がオフ状態になるので、摺動子7の移動量の連続変化する一方で出力電圧は断続する。要するに、第2実施形態に係る可変抵抗器によっても、摺動子7の移動量の連続した変化に対し、段階的、かつ、断続的に異なる高さの出力電圧を生起させることができる。したがって、出力電圧が各段階のうちのいずれに該当するものであるかの判定の確実性の向上に貢献でき、電気機器の制御に利用する場合における可変抵抗器の扱い安さの向上に貢献できる。   In the second embodiment, when the slider 7 slides between all or some of the first conductor portions 21 and the like on the resistance circuit portion 40, the conductor portion and the insulator portion (the first insulator portion 41 and the like). Any one of them). Since the conductor portions and the resistor portions are alternately connected, if the slider 7 moves between the plurality of conductor portions, the output voltage increases or decreases stepwise as shown in FIG. The slider 7 always passes through the insulator part before and after contacting the conductor part, and the slider 7 and the resistance circuit part 40 are electrically disconnected during the passage, that is, variable. Since the resistor is turned off, the output voltage is intermittent while the moving amount of the slider 7 is continuously changed. In short, even with the variable resistor according to the second embodiment, it is possible to generate output voltages of different heights stepwise and intermittently with respect to a continuous change in the moving amount of the slider 7. Therefore, it is possible to contribute to improving the reliability of determination as to which of the stages the output voltage corresponds to, and to contribute to improving the handling ease of the variable resistor when used for the control of electrical equipment.

特に第2実施形態においては、第1導体部21等はそれぞれ第1抵抗体部11等の列から摺動子7の軌道8上に突出して位置する。これにより、摺動子7の摺動方向において隣り合った抵抗体部の間隔寸法51〜53によって、同方向における第1導体部21等の寸法が制限されず、すなわち間隔寸法51〜53よりも大きく設定できるので、段階的な出力電圧の増加量(例えば図7に示す出力電圧L1とL2の差の電圧)とは独立して所定の電圧の維持距離(例えば図7のDaやDbなどの長さ)を大きくできる。つまり、摺動子7の摺動方向における第1導体部21等の寸法の自由度を、第1実施形態よりも大きくすることができる。   In particular, in the second embodiment, the first conductor portion 21 and the like are positioned so as to protrude from the row of the first resistor portion 11 and the like on the track 8 of the slider 7. Thereby, the dimension of the 1st conductor part 21 grade | etc., In the same direction is not restrict | limited by the space | interval dimension 51-53 of the resistor part adjacent in the sliding direction of the slider 7, That is, rather than the space | interval dimension 51-53. Since it can be set to a large value, a predetermined voltage maintaining distance (for example, Da or Db in FIG. 7) is independent of the stepwise increase in output voltage (for example, the difference voltage between the output voltages L1 and L2 shown in FIG. 7). (Length) can be increased. That is, the degree of freedom of dimensions of the first conductor portion 21 and the like in the sliding direction of the slider 7 can be made larger than that in the first embodiment.

なお、前述の第2実施形態に係る可変抵抗器も、操作部材が直線的にスライドされるものであり、これに対応して抵抗回路部40が直線状に形成されていたが、本発明はこれに限定されるものではなく、操作部材が回転操作されるものであって、抵抗回路部40に相当する抵抗回路部が操作部材の回転中心線周りに円弧状に形成されたものであってもよい。   In the variable resistor according to the second embodiment described above, the operation member is linearly slid, and the resistance circuit portion 40 is formed linearly corresponding to this, but the present invention is not limited to this. However, the present invention is not limited to this, and the operation member is rotated, and the resistance circuit portion corresponding to the resistance circuit portion 40 is formed in an arc shape around the rotation center line of the operation member. Also good.
