Description

本発明は、ボタン数と操作数を極力減らし、勘違いや誤操作を起す複雑な調整を簡易化し、運転士の労力軽減を図った車両用バックミラーに関する。 The present invention relates to a vehicle rearview mirror that reduces the number of buttons and the number of operations as much as possible, simplifies complicated adjustments that cause misunderstandings and erroneous operations, and reduces the labor of a driver.

従来、車両用バックミラーの視界調整は、１ミラー当たり水平と垂直２方向を各正逆２つ、
計４つのボタンスイッチ（以下ボタンと言う）を一々押換え可逆調整をしていた。
しかし、バックミラーは左右にあるからボタンは切換えスイッチで共用し操作をするが、このため視線は、バックミラーの映像と離れた位置のボタン間を頻繁に往復し、所在確認をしながらで映像観察に集中できず、誤操作が多く常に反復修正を伴い大変手間がかかった。 Conventionally, the field of view of a vehicle rearview mirror is adjusted in two horizontal and vertical directions per mirror.
A total of four button switches (hereinafter referred to as “buttons”) were pressed and adjusted in a reversible manner.
However, since the rear-view mirror is on the left and right, the buttons are shared by the changeover switch, but for this reason, the line of sight frequently goes back and forth between the rear-view mirror image and the button at a distant position, and confirms the location. It was difficult to concentrate on the observation, and there were many erroneous operations, and it was always time-consuming with repeated corrections.

このアオリ作用は、ミラー裏面中心をピボットで旋回自在に取付け、水平垂直２方向に突
棒を連結し、当棒の上下作用で駆動するが、ネジを使うために切端があり、駆動モータは
必然的に正転・逆転の切換え操作をする構成に成っていた。
而して、ボタンを押替えず可逆操作ができる提案も有るが（特許文献1参照）、右巻きと左巻きのクロス溝を１軸に交差成形し上下端を繋ぐので、モータは一方回転のみで従動ピンを上下動するものであり、ミラーアオリ動作はエンドレスにしたものである。
更に、ミラー調整スイッチをレバーで前後、左右、味噌擂り運動状に捻り、操作するものもあるが
（特許文献２・３参照）、レバーを持ち変えず映像観察に集中できるものもある。 This tilting action pivots the mirror back center with a pivot, connects the projecting rods in two horizontal and vertical directions, and drives with the vertical motion of the rod, but there is a cut end to use screws, and the drive motor is inevitable Therefore, it was configured to perform forward / reverse switching operation.
Thus, although there is a proposal that allows reversible operation without changing the button (see Patent Document 1), the right-handed and left-handed cross grooves are cross-molded on one axis and the upper and lower ends are joined, so the motor can only rotate in one direction. The driven pin moves up and down, and the mirror tilt operation is endless.
In addition, some mirror adjustment switches are operated by twisting the mirror adjustment switch back and forth, left and right, and in taste buds (see Patent Documents 2 and 3), but there are also those that can concentrate on video observation without changing the lever.

以上述べた内、従来のバックミラーは、ネジの推力でアオリ駆動をするから回転力は微弱で済み、ピッチが細いので突棒送りが精密で微調ができ、走行振動による映像歪みもない利点はあるが、ボタン押替えは操作数多く、位置確認のため広範な視線移動が伴い映像観察に集中できず、勘違いやボタンの空押し、誤操作を起して、反復修正を伴い、非常に煩わしい課題があった。 Among the above-mentioned, the conventional rearview mirror is tilt-driven by the thrust of the screw, so the rotational force is very weak, and the pitch is thin, so that the tip feed can be precise and fine-tuning, and there is no image distortion due to running vibration However, there are many operations to change buttons, and it is not possible to concentrate on video observation due to a wide range of line of sight movement for position confirmation, causing misunderstandings, idle button presses, incorrect operations, repeated corrections, and extremely troublesome problems. there were.

従って、調整時間は分単位の長時を要し、馴れた人でも時には３０分を越え、車の便利さに照らせば一仕事終わるロスタイムであり、家庭や職場での供用車、或いは長距離走行の運転交代では、始業時の操作に悩まされ、長年この不便を強いられてきた経緯がある。
即ち、左右のバックミラーを切替えたつもりが不調に終わり、気付かぬまま視線を別のミラーに移し操作をするから、折角調整したミラーの適正視界を大きく狂わし、再調整に長時間を要すことも多く、このようなときは気分も滅入る大きな課題であった。 Therefore, the adjustment time takes a long time in minutes, and even a familiar person sometimes exceeds 30 minutes, and in terms of the convenience of the car, it is a loss time to finish one work, a service car at home or work, or long distance running In the change of driving, there are circumstances that have been troubled by the operation at the start of work and have been forced to have this inconvenience for many years.
In other words, the intention to switch the left and right rearview mirrors ended in a bad state, and the operation was moved to another mirror without being aware of it. There were many things, and it was a big problem that I felt depressed at such times.

また、アオリネジの雌ネジは、ネジ端部の脱落防止のためストッパーを設けるが、螺合に
より噛込み固着を生じ、この防止のため弾性爪を雌ネジに代用し、端部で大きな固着負荷
が掛かると当爪を撓ませネジ山飛ばしをするが、強力な推力に抗するため大きな離脱音と振
動を伴い、故障と見間違う問題もある。 In addition, the female screw of the tilt screw is provided with a stopper to prevent the screw end from falling off, but it is bitten and fixed by screwing, and an elastic claw is substituted for the female screw to prevent this, and a large fixing load is applied at the end. When hooked, the claws are bent and the threads are skipped, but there is also a problem that can be mistaken for a failure, accompanied by loud separation noise and vibration to resist strong thrust.

更には、ボタン配置を明確にするため水平垂直の十字配列にするが、四隅と中央が空域で、
ボタン９個分の占有面積を要し、この広面積は操作性がよい位置に必ずしも装着できず、所在確認が難しく、空押しエラーが多発し動作不調に気付く時間ロスは大きな課題である。 Furthermore, in order to clarify the button arrangement, it is made a horizontal and vertical cross arrangement, but the four corners and the center are airspace,
An area occupied by nine buttons is required, and this large area cannot always be mounted at a position where operability is good, it is difficult to confirm the location, time loss that frequently occurs due to a number of pressing errors, is a big problem.

更に、特許文献1は、左右巻溝のクロススレッドスピンドルなるクロス溝を従来のミラーアオリネジに替えただけのもの、同溝は上下端を連結し一方回転でピンが上下しアオリ作用をするので普通のボタンが使え、押替えも不要である点はよいが、ピンの移行を良くするため溝の捻じれ傾斜即ちピッチが大きくなり、僅かな軸回転でアオリ変位は過大になり微調整には向かない。 ピンの押し進め傾斜角も大きく高負荷がかかり、この高回転力が惰性停止を抑制し、位置決め精度がよいとしているが力学的な欠点であり、あたかも利点の如き主張は見当違い甚だしく、本発明の軽動作による瞬間停止とは比較に成らないものである。 Furthermore, in Patent Document 1, the cross groove, which is the cross thread spindle of the left and right winding grooves, is simply replaced with a conventional mirror tilt screw. It is good that normal buttons can be used and switching is not necessary, but to improve pin transition, the twisted inclination of the groove, that is, the pitch becomes large, and the tilt displacement becomes excessive with a slight rotation of the shaft. Not suitable. The pin push-in inclination angle is large and a high load is applied, and this high rotational force suppresses inertia stop and positioning accuracy is good, but it is a mechanical defect, as if the claims such as advantages are misplaced. It is not comparable to a momentary stop due to a light operation.

その点、特許文献２と３はボタンに変わる調整手段であり、対象は従来のアオリネジによる突
棒の上下動によるバックミラーの遠隔操作器で本発明とは同一ジャンルであるが、可逆調整手段は従来のままで改善されておらず、多ボタン押替え操作を１ノブで前後左右傾倒押引し、またレバーの捻り動作に替えたものであるから、従来の操作を念頭に行う調整は一般的に難解であり、レバーの捻り動作による応力は精密レバー機構に及ぼす操作負担が大きく、摩耗や損傷など強度上の課題を持つ。 In that respect, Patent Documents 2 and 3 are adjustment means that change into buttons, and the target is a conventional remote control device for a rearview mirror by a vertical movement of a protruding rod by a tilt screw, which is the same genre as the present invention. Since it has not been improved as before, the multi-button switching operation is tilted back and forth, left and right with a single knob, and replaced with the twisting operation of the lever. However, the stress due to the twisting operation of the lever has a large operational burden on the precision lever mechanism, and has strength issues such as wear and damage.

また実装に於いては、当該複雑動作のレバーが突出し異様であり、車両衝撃時の安全上も突起を嫌う内装品において好ましくなく、捻り作用は拳大の捻り占有空間が必要であるから、機器自体小型でも、操作空間が広く占有され必ずしも小さいとは言えない課題もある。 In mounting, the complicated operation lever protrudes and is unusual, and it is not preferable for interior products that dislike the protrusion for safety in the event of vehicle impact, and the twisting action requires a space occupied by a fist-sized device. Even if it is small in itself, there is a problem that the operation space is widely occupied and cannot always be said to be small.

本発明は、斯様な従来機構の持つ多くの問題を解決するため、ボタン数と操作数を極力減らし、勘違いや誤操作が起きない複雑な調整を簡素化し、運転交代時にかならず付随する煩わしさを解消する車両用バックミラーの実現を目的とするものである。 In order to solve many problems of such a conventional mechanism, the present invention reduces the number of buttons and the number of operations as much as possible, simplifies complicated adjustments that do not cause misunderstandings and erroneous operations, and always adds the troublesomeness that accompanies when changing driving. The purpose is to realize a vehicle rearview mirror that can be eliminated.

そして、本発明は、上記目的を達成するため二つの手段を挙げる。
その第一手段は、基本型（図１〜３）で、従来のようにミラーの映像を観察しながら適正視界を得るものであるが、ボタンは押しでミラーアオリを可逆させ、放しでは瞬間停止をして適正視界位置を正確に得るもので、ボタンの押替えがなく単純な押し放し操作だけであるから、視線はミラー映像から離れることがないものである。 The present invention enumerates two means to achieve the above object.
The first means is a basic type (Figs. 1 to 3), which obtains an appropriate field of view while observing the mirror image as in the past, but reversing the mirror tilt by pressing the button and momentarily stopping when released. Thus, the proper visual field position can be obtained accurately, and there is no need to push the button, and only a simple pressing operation is performed. Therefore, the line of sight does not leave the mirror image.

第二手段は、全一括調整型（図４・５）で、映像観察操作は全く不用なもの、個々の運転姿勢を選択スイッチで設定し、ボタンで起動するだけ、左右のバックミラー水平・垂直４モータは一括４連で同時に作動し、アオリ検知信号が運転姿勢設定回線に入ると自動的に瞬間停止をするものである。 The second means is an all-in-one adjustment type (Figs. 4 and 5) that does not require any video observation operation. Each driving posture is set with a selection switch and activated with a button, the left and right rearview mirrors are horizontal and vertical. The four motors operate simultaneously in four batches, and automatically stop instantaneously when the tilt detection signal enters the driving posture setting line.

これらの制御は、出力極性を変換する論理回路と同極信号を発する中継器でモータドライバを制御し、モータに正転・逆転・瞬間停止をさせるが、上記の基本型・全一括調整型、全機種に共通の制御ユニット.により作動するものである。 These controls control the motor driver with a relay circuit that generates the same polarity signal as the logic circuit that converts the output polarity, and causes the motor to rotate forward, reverse, and instantaneously stop. It is operated by a control unit common to all models.

而して、ミラーアオリの最大・最少変位での可逆動作は論理回路の作用によるが３種あり、
その１は、アオリネジ連動の摺動接点の回動が反転端子に接触し発生する信号であり、これを当該論理回路の入力端子に印加し、同論理回路の出力極性変換作用によるもので図１に示し請求項１に記載したものである。 Thus, the reversible operation with the maximum and minimum displacement of the mirror tilt depends on the action of the logic circuit.
The first is a signal generated by the rotation of the sliding contact interlocking with the tilt screw coming into contact with the inverting terminal, which is applied to the input terminal of the logic circuit and is due to the output polarity conversion action of the logic circuit. And is described in claim 1.

その２は、ミラー裏面のアオリ動作を直接発信器にあて可逆信号を得て論理回路に印加、上記機能同様に出力極性を変換しモータを操作するもので、図２に示し請求項２に記載したが、ミラー裏面が降下するとマイクロスイッチに接触する例で図示した。 The second is that the tilt operation on the back of the mirror is directly applied to the transmitter to obtain a reversible signal and applied to the logic circuit, and the output polarity is converted and the motor is operated in the same manner as the above function. However, an example is shown in which the microswitch comes into contact with the back of the mirror when it is lowered.

その３は、アオリネジの回転数をカウンタＩＣに出力させ、その計数信号を論理回路の入力端子に印加し、当該論理回路の出力極性を変換するものであり、これをモータドライバに入力しモ−タを可逆する構成にして図３に示し請求項３に記載したものである。 The third method is to output the rotation speed of the tilt screw to the counter IC, apply the count signal to the input terminal of the logic circuit, and convert the output polarity of the logic circuit. 3 is shown in FIG. 3 in a reversible configuration.

而して、ボタン放しでは中継器出力は負から正に変わり２入力端子を持つモータドライバへは２分して同極印加とするが、そのモータドライバの性質から作動中のモータは瞬間停止し、所定位置に正確に止められ、停止中のモータは停止を保持するものである。 Thus, when the button is released, the repeater output changes from negative to positive and the motor driver with two input terminals is divided into two to apply the same polarity. However, the operating motor stops instantaneously due to the nature of the motor driver. The motor that is stopped at a predetermined position and is stopped holds the stop.

即ち、上記の動作は、ボタン押しでモータドライバの２入力端子に論理回路の出力である正負または負正と印加し、モータを正転または逆転させ、放しでは中継器の出力を正正としモータドライバに印加しモータを瞬間停止するが、ボタンの押し作用は調整終了までは放すことはなく、視線はミラー映像から離れることがなく、勘違いや空押し、修復操作が起らないから、アオリ動作半サイクル内の短時間調整ができるものである。 That is, the above operation is performed by applying positive / negative or negative / positive output, which is the output of the logic circuit, to the two input terminals of the motor driver by pressing the button, causing the motor to rotate forward or reverse, and releasing it to set the output of the repeater to positive / negative The motor is momentarily stopped when applied to the driver, but the push action of the button is not released until the adjustment is completed, the line of sight does not leave the mirror image, misunderstanding, idle push, and repair operation do not occur, so the tilt operation It can be adjusted for a short time within a half cycle.

更に、第二の全一括調整型は、図１記載の反転端子間を複数に分割して停止端子とし、また図３記載のカウンタＩＣでは既設の複数の中間端子があるからこれを停止端子に用い両停止端子は選択スイッチを介して図４図５のように中継器に接続し、当該選択スイッチにて個々の運転姿勢を設定しボタンで起動させるものである。
而して、左右バックミラーの水平・垂直４モータは映像観察などの一切の操作がないから４連動で作動でき、上記運転姿勢設定回線にアオリ変位信号が入ると瞬間停止し自動調整ができるもので、反転端子間の停止端子構成は図４に示し請求項４に記載、カウンタＩＣの既設中間端子を停止端子とした構成は図５に示し請求項５に記載したものである。 Further, in the second all batch adjustment type, the inversion terminals shown in FIG. 1 are divided into a plurality of stop terminals, and the counter IC shown in FIG. 3 has a plurality of existing intermediate terminals. Both stop terminals used are connected to a repeater as shown in FIG. 4 and FIG. 5 via a selection switch, and each driving posture is set by the selection switch and activated by a button.
Thus, the horizontal and vertical 4 motors of the left and right rearview mirrors can be operated in conjunction with 4 because there is no operation such as video observation, and when the tilt displacement signal enters the driving posture setting line, it can be instantaneously stopped and automatically adjusted. The configuration of the stop terminal between the inverting terminals is shown in FIG. 4 and described in claim 4, and the configuration in which the existing intermediate terminal of the counter IC is used as the stop terminal is shown in FIG. 5 and described in claim 5.

本発明は、基本的にアオリ最大最少位置でボタンの押換えがなくボタンは押すだけ、ゆえに視線は映像観察に集中でき誤操作は起きず、ゆとりあるアオリ速度と相まって適正視界が明確に掴め、とっさにボタンを放し、モータはオーバランをせずに瞬間停止をするので、正確に視界位置に止まり、従来のようにバック寸動で微調修復をする手間が省ける効果がある。 In the present invention, basically, the button is not pressed at the maximum and minimum position of the tilt, and the button is pressed.Therefore, the line of sight can be concentrated on the image observation, and no erroneous operation occurs. When the button is released, the motor stops instantaneously without overrunning, so that the motor can stop at the position of view accurately, and there is an effect of saving the trouble of fine adjustment restoration by back movement as in the prior art.

ボタン押換え無しは、可逆作用をアオリネジ切端で弾性爪によるネジ飛ばしが起きず、従来の如きネジの離脱衝撃音や振動は起らず、静粛で円滑な動作が得られ耐久性も向上する。
更に、視線が映像観察に集中して操作数が従来の半分に成るだけではなく、勘違いや空押し誤作動による反復修正操作がなくなるから総体的な工数が減り、楽に高速調整ができる効果がある。 Without button switching, reversible action is not caused by the elastic claw at the end of the tread screw, and there is no screw release impact sound or vibration as in the conventional case, and a quiet and smooth operation is obtained and durability is improved.
In addition, the line of sight concentrates on video observation and the number of operations is halved compared to the conventional method. In addition, there is no need for repeated correction operations due to misunderstandings or false pressing malfunctions. .

従来、ボタン配置は水平垂直操作の明示上十字配置とし、さらに左右ミラーの切換スイッチを要したが、当発明のボタンは単純な押放だけであるから左右切換えスイッチもなく、４ボタンを２個２列配置になり、空域がないから小面積にまとまりコンパクトである。 更に、家電等で多く使われ品質よく安価な市販ボタンが使え、実施に際し新たな生産設備等は不要で経済効果も著しくよい。 In the past, the button layout was an explicit cross arrangement for horizontal and vertical operations, and a left / right mirror changeover switch was required. However, since the button of the present invention is a simple push-and-release switch, there is no left / right changeover switch. Since it is arranged in two rows and there is no airspace, it is compact in a small area. Furthermore, commercially available buttons that are often used in home appliances and the like and can be used at low cost can be used, and no new production facilities are required for implementation, and the economic effect is remarkably good.

第二手段の全一括調整型は、基本型の反転端子間に複数の停止端子を設けるか、カウンタＩＣの中間端子を停止端子に転用するので、基本型のボタン放で瞬間停止をさせるのに対し、選択スイッチによる運転姿勢設定で自動停止させ映像観察は無用になる効果がある。 The all-in-one adjustment type of the second means is provided with a plurality of stop terminals between the inversion terminals of the basic type, or the intermediate terminal of the counter IC is diverted to the stop terminal. On the other hand, there is an effect that the video observation is made unnecessary by automatically stopping by setting the driving posture by the selection switch.

バックミラーの視界調整を映像観察で行う場合は、視線を４モータ同時に追うことはできないから、必然的に一つ一つ順送り制御の直列操作になるが、本発明の誤動作修復がなく楽に高速調整ができることから何ら不便を感じない効課がある。
その点、全一括調整型は、選択スイッチで運転姿勢を設定しボタン起動だけであるから、この他に人の介在はなく自動並行制御ができ、運転交代時の煩わしさは全て解消され、映像観察では成し得なかった運転当事者以外の操作までこなす効果はかってなかったものである。 When visual field adjustment of the rearview mirror is performed by visual observation, it is not possible to simultaneously follow the line of sight of four motors, so it is inevitably necessary to perform serial operation of sequential feed control one by one. There is an effect that does not feel any inconvenience from being able to.
On the other hand, the all batch adjustment type only sets the driving posture with the selection switch and activates the button, so there is no other human intervention and automatic parallel control is possible. There was no effect of handling operations other than the driver who could not be achieved by observation.

以下、第一に、ボタン押しでアオリ作用をし、放しで瞬間停止をする映像観察調整式の「基本型」で車両用バックミラーの実施形態を図１〜３に沿って説明する。
図１の摺動接点調整ユニットに於いて、１はプリント基板、２は摺動接点、３は当接点２の軌
跡、４はプリント基板１に焼き付けた反転端子で軌跡３上にアオリ最大最少位置に対設したもの、５は摺動接点２に一体のコモン接点でリング６に摺動するように設置し、当該６は反転端子４と共にプリント基板１に焼付けた導電体である。 In the following, first, an embodiment of a vehicle rearview mirror of a video observation adjustment type “basic type” that performs a tilting action by pressing a button and instantaneously stops when released will be described with reference to FIGS.
In the sliding contact adjusting unit of FIG. 1, 1 is a printed circuit board, 2 is a sliding contact, 3 is a locus of a contact point 2, 4 is a reverse terminal baked on the printed circuit board 1, and a tilt maximum minimum position on the locus 3 The reference numeral 5 is installed on the sliding contact 2 so as to slide on the ring 6 with an integral common contact, and the reference numeral 6 is a conductor baked on the printed circuit board 1 together with the reverse terminal 4.

７は２つの入力端子に反転端子４を各々接続する出力極性を変換する論理回路、８は出力端子を２分し各々は論理回路７の２出力に合成した中継器で、その入力端子には図示しないがボタンを設け、合成出力端子はモータドライバ９の入力端子に接続し、２出力端子にはモータ１０を接続し、ミラーアオリを作動すると共に軸１１で摺動接点２を連係回動させるものある。 7 is a logic circuit that converts the output polarity to connect the inverting terminal 4 to the two input terminals, 8 is a repeater that divides the output terminal into two and each synthesizes the two outputs of the logic circuit 7, and the input terminal has Although not shown, a button is provided, the combined output terminal is connected to the input terminal of the motor driver 9, the motor 10 is connected to the two output terminals, the mirror tilt is operated, and the sliding contact 2 is linked and rotated by the shaft 11. There are things.

図２のアオリ直動調整ユニットは、上記摺動接点２に代わるもので、１２はミラー裏面Ｂのアオリ最大最少位置に設けた反転信号の発信器であり、図はマイクロスイッチで図示した。 図３の回転計数調整ユニットは、図９のようにアオリネジ１３と同軸にカム１４を設け、これに計数器１５を接触発信させ、当信号はカウンタＩＣ１６に入力し、その出力の初動端子Ｃとアオリ最大計数出力端子Ｄを上記同様に論理回路７にそれぞれ印加する構成とし、計数器１５はマイクロスイッチで図示したが、回転計数器として作動するシャフトエンコーダや磁気検知センサなども使用できるものである。 The tilting linear movement adjusting unit of FIG. 2 is an alternative to the sliding contact 2, wherein 12 is a reverse signal transmitter provided at the tilting minimum and minimum position of the mirror back surface B, and the figure is illustrated by a microswitch. The rotation counting adjustment unit of FIG. 3 is provided with a cam 14 coaxially with the tilt screw 13 as shown in FIG. 9, and a counter 15 is contacted and transmitted to this, and this signal is input to the counter IC 16 and the initial terminal C of its output and The tilt maximum count output terminal D is applied to the logic circuit 7 in the same manner as described above, and the counter 15 is shown as a microswitch, but a shaft encoder or a magnetic detection sensor that operates as a rotational counter can also be used. .

第二は、図４・図５に示す運転姿勢設定の「全一括調整型」の実施形態であり、図４は、図１の対設した反転端子４間に複数の停止端子１７を設け、それぞれは、一般運転姿勢の差を適宜区分したもので、それらは選択スイッチ１８を介し中継器８に接続する。 The second is an embodiment of “all batch adjustment type” of the driving posture setting shown in FIG. 4 and FIG. 5, and FIG. 4 is provided with a plurality of stop terminals 17 between the opposite inverting terminals 4 of FIG. Each of them is obtained by appropriately classifying the difference in the general driving posture, and they are connected to the repeater 8 via the selection switch 18.

図５は、カウンタＩＣ１６の場合であり、カウンタＩＣ自体は中間端子１９が複数既設されているから、之を上記停止端子１７同様機能に転用し、当該運転姿勢区分を割当て矢張り選択スイッチ１８を介し中継器８に接続する。
即ち、摺動接点２の駆動と計数器１５の計数機能は、それぞれミラーアオリに適正視界位置を決める同期手段に使われるもので、運転姿勢区分は細かい程調整精度は高くなるが、実用上ある程度の許容差が有り、あまり神経質に細分化する必要はない。 FIG. 5 shows the case of the counter IC 16. Since the counter IC itself has a plurality of intermediate terminals 19, it is used for the same function as the stop terminal 17, assigns the driving posture section, and sets the arrow selection switch 18. To the repeater 8.
In other words, the driving of the sliding contact 2 and the counting function of the counter 15 are used as synchronization means for determining the proper field of view position in a mirror tilt. The finer the driving posture section, the higher the adjustment accuracy, but to some extent practically. Therefore, it is not necessary to subdivide into nervousness.

以上、図１〜５のユニットは、摺動接点、アオリ直動、回転計数、停止端子による運転姿勢
設定、中間端子による運転姿勢設定の５種を、論理回路７と中継器８に組ませモータドライバ
９を制御するユニットで、左右のバックミラーの水平・垂直４調整を個々に駆動するものである。
従来のバックミラーはボタン押替えによる可逆操作でボタン数も多いが、これに比べれば操作数は半分、ボタンの押替え操作もなく、勘違い誤操作・空押し・逆転微調整を回避し、総体的省
力と操作時間短縮に極めて有用である。
さらに、選択スイッチ１８による運転姿勢設定では、スタート後の操作は一切なく装置任せの自
動制御で、古来よりミラー調整は映像観察によるとしてきた既成概念を打ち破るものである。 As described above, the units shown in FIGS. 1 to 5 are configured by combining the logic circuit 7 and the repeater 8 with five types of sliding contact, tilt linear motion, rotation count, driving posture setting using a stop terminal, and driving posture setting using an intermediate terminal. This unit controls the driver 9 and individually drives the horizontal and vertical 4 adjustments of the left and right rearview mirrors.
The conventional rearview mirror has a reversible operation by button switching and a large number of buttons. Compared to this, the number of operations is half, there is no button switching operation, avoids misunderstanding mistakes, idle pressing, and reverse rotation fine adjustment, and overall It is extremely useful for saving labor and shortening operation time.
Furthermore, in the driving posture setting by the selection switch 18, there is no operation after the start and automatic control is left to the device, and the mirror adjustment breaks the established concept that has been based on video observation since ancient times.

続いて、ミラーアオリ機構とアオリ変位検知発信機構の関係を図６〜９で説明すると、ミラー

点２の回転角整合は軸１１のエンドギヤ２４と中継ギヤ２５で連係させ、これら機構は筐体２６に収納されている。 尚、Ｅはバックミラーのハウジング、Ｐはピボットである。 Subsequently, the relationship between the mirror tilt mechanism and the tilt displacement detection transmission mechanism will be described with reference to FIGS.
The drive gear 20 rotates the tilt screw 13 that has a tilt action on A. The drive gear 20 meshes with a worm 21 coaxial with the motor 10, and a long nut 22 that is screwed to the tilt screw 13 is moved up and down. A projecting rod 23 connected to the rear surface B of A is placed, and the rotational speed of the drive source tilt screw 13 and the rotational angle alignment of the sliding contact 2 are linked by the end gear 24 and the relay gear 25 of the shaft 11. The body 26 is accommodated. E is a rear mirror housing, and P is a pivot.

以下、上記構成の動作を説明すると、図１の摺動接点と反転端子による調整ユニットでは、
ボタン押しで論理回路７の正負または負正出力信号は中継器８を経てモータドライバ９に印加しモータ１０に可逆作用をする。
このとき、ミラーアオリと共に軸１１が連動するから摺動接点２が回動し、リング６の接地がコモ
ン接点５を経て回動先の反転端子４に摺動接点２が接触伝導し、論理回路７の入力端子に印加される。
よって、論理回路７の出力電圧の極性が変換し、伝達さきのモータドライバ９によりモータ１０は逆転して、対設する反転端子４に向け回動するもので、当該反転端子４に接すると再度反転し最初の回動に戻り、この動作がエンドレスで続き、ミラ−Ａのアオリ作用をすることになる。 Hereinafter, the operation of the above configuration will be described. In the adjustment unit with the sliding contact and the reverse terminal in FIG.
When the button is pressed, the positive / negative or negative / positive output signal of the logic circuit 7 is applied to the motor driver 9 via the repeater 8 and reversibly acts on the motor 10.
At this time, since the shaft 11 is interlocked with the mirror tilt, the sliding contact 2 is rotated, and the ground contact of the ring 6 is conducted through the common contact 5 and the sliding contact 2 is contact-conducted to the reversing terminal 4 at the rotation destination. 7 is applied to the input terminal.
Therefore, the polarity of the output voltage of the logic circuit 7 is changed, and the motor 10 is reversely rotated by the motor driver 9 before being transmitted, and is rotated toward the reverse terminal 4 provided. It reverses and returns to the first rotation, this operation continues endlessly, and mirror-A tilting action is performed.

従って、ボタン押換えなしはボタンの設置位置確認の必要がなく、視線は適正視界位置の観
察に集中するから見過ごすことがなく、所定位置で間髪を入れずボタンを放し正確に瞬間停止をさせることができオーバランが起きず、従来のようにバック寸動による修復操作が不要になる。 即ち、ボタンを押し続ければアオリ動作はエンドレスになるが、適正視界位置を逃さない効果はアオリ反サイクル内の短時間で視界調整ができ、反復調整をすることはない。 Therefore, without pressing the button, there is no need to check the installation position of the button, and the line of sight concentrates on the observation of the appropriate field of view, so it will not be overlooked. Therefore, overrun does not occur, and a repair operation by back jogging is not required as in the prior art. In other words, if the button is kept pressed, the tilt operation becomes endless, but the effect of not losing the proper view position can be adjusted in a short time within the tilt anti-cycle, and no repeated adjustment is performed.

図２のアオリ直動調整ユニットでは、ボタン押しでミラーをアオリ、当該ミラー裏面Ｂで
発信器を作動させ、論理回路７に反転信号を送り、出力電圧の極性を反転させることは上記に同じで、モータドライバ９を経てモータ１０が駆動する。 このアオリ最大最小変位を検知する発信器１２はマイクロスイッチで描画しているが、図８に示す通りミラー裏面Ｂ中央を支えるピボットＰを振分けに左右に水平垂直線上に配置したもので、筐体２６の端部に固定しているが、上記変位が検知できる任意の位置に設置すればよい。 In the tilt linear motion adjustment unit of FIG. 2, the mirror is tilted by pressing the button, the transmitter is operated on the mirror back surface B, the inversion signal is sent to the logic circuit 7, and the polarity of the output voltage is inverted as described above. The motor 10 is driven via the motor driver 9. The transmitter 12 for detecting the maximum and minimum displacement of the tilt is drawn by a micro switch. As shown in FIG. 8, the pivot P supporting the center of the mirror back B is arranged on the horizontal and vertical lines to the left and right. Although it fixes to the edge part of 26, what is necessary is just to install in the arbitrary positions which can detect the said displacement.

図３の計数器１５はアオリネジの回転数を計測するもので、このミラーアオリ変位はネジのピッチに回転数を掛けた値で得られるので、これを計測すれば反転位置が分ものである。
依って、計数信号をカウンタＩＣ１６の初動端子Ｃとアオリ最大計数出力端子Ｄを上記同 様に論理回路７の入力端子に印加すれば、当出力電圧の極性を変換し、以後の動作は上
記２例に全く同じでモータ１０を可逆するものである。
次いで、ボタンを放すと、中継器８の入力は負になるから、出力は正で、これを２分し論理回路７の結線に合成されているので、モータドライバ９の２入力端子には正の同極が印加され、作動中のモータは瞬間停止をすることになる。 The counter 15 in FIG. 3 measures the rotation speed of the tilt screw, and the mirror tilt displacement is obtained by multiplying the pitch of the screw by the rotation speed.
Therefore, if the count signal is applied to the input terminal of the logic circuit 7 in the same manner as described above, the polarity of the output voltage is converted, and the subsequent operation is performed as described above. It is exactly the same as the example, and the motor 10 is reversible.
Next, when the button is released, the input of the repeater 8 becomes negative, so the output is positive, and this is divided into two and synthesized into the connection of the logic circuit 7. Therefore, the positive input is applied to the two input terminals of the motor driver 9. Are applied, and the motor in operation stops instantaneously.

図４の動作は、選択スイッチ１８で個々の運転姿勢を選択設定し、ボタンで起動するもので、論理回路７の出力極性を可逆変換することは上記３種と同じである。
しかして、対設した反転端子４・４間に複数の停止端子１７が設けられ選択スイッチ１８を介し中継器８に接続しているから、選択該当停止端子回線に信号が入ると中継器８に正の同極電圧を発することで、この先、モータドライバ９に当該同極信号を印加し、モータ１０を自動的に瞬間停止することになる。 The operation of FIG. 4 is performed by selecting and setting individual driving postures with the selection switch 18 and starting with a button, and reversible conversion of the output polarity of the logic circuit 7 is the same as the above three types.
Since a plurality of stop terminals 17 are provided between the opposite inverting terminals 4 and 4 and are connected to the repeater 8 via the selection switch 18, when a signal enters the selected stop terminal line, By generating a positive homopolar voltage, the homopolar signal is applied to the motor driver 9 and the motor 10 is automatically stopped instantaneously.

図５の動作は、選択スイッチ１８で個々の運転姿勢を選択設定し、ボタンで起動するもので、アオリネジ１３に設けたカム１４で計数器１５を作動するが、この発信信号は順次カウンタＩＣ１６に印加され、初動端子Ｃと最大アオリ対応端子Ｄに出力した時は、接続先の論理回路に印加され、当論理回路出力は極性が反転してモータドライバ９により、モータを可逆しアオリ作用をするまでは、図３と同じである。 The operation shown in FIG. 5 is performed by selecting and setting individual driving postures with the selection switch 18 and starting with a button. The counter 15 is operated by the cam 14 provided on the tilt screw 13. This transmission signal is sequentially sent to the counter IC 16. When it is applied and output to the initial movement terminal C and the maximum tilt corresponding terminal D, it is applied to the connected logic circuit, the polarity of the logic circuit output is reversed, and the motor driver 9 reverses the motor and performs the tilt action. The process up to is the same as FIG.

而して、この場合は複数の中間端子を停止端子にしているので接続した選択スイッチで運転姿勢を選択すると、この選択回線に信号が入ると接続さきの中継器から正の同極信号が発し、モータドライバ９の入力端子に印加され当該モータドライバ９の性質からモータ１０は瞬間停止をすることになる。 Thus, in this case, since a plurality of intermediate terminals are used as stop terminals, when a driving posture is selected with the connected selection switch, a positive homopolar signal is emitted from the repeater before connection when a signal enters the selected line. The motor 10 is applied to the input terminal of the motor driver 9 and the motor 10 stops instantaneously due to the nature of the motor driver 9.
