の良いものがなく、動力窓開閉装置等で）手を挾む危険
性があった。Until now, there has been no suitable device for detecting when an object has been pinched, especially when there is no device that is conveniently placed near the window glass of a car. There was a risk.
よって、本発明の目的は検出部を線状に長く配設でき、
コンパクトで見ばえが良い物体抑圧検出装置にすること
にある。Therefore, an object of the present invention is to enable the detection section to be arranged in a long linear manner,
The objective is to create an object suppression detection device that is compact and has a good appearance.
以下、本発明装置を自動車の窓部に取付けた一実施例に
ついて説明する。An embodiment in which the device of the present invention is attached to a window of an automobile will be described below.
第１図において、１は窓カラスであり公知の動力窓開閉

光を良く通ず棒状の光ファイバーの群体である。５は発
泡ウレタンゴムであり、ゴノ、カバー３内に充填され、
前述の光ファイバーからなる光伝導部材４を位置決めす
るものである。In FIG. 1, reference numeral 1 denotes a window crow, which is driven in the direction of the arrow 1 by a known power window opening/closing device to close the window 2. 2 is a part of the car body; 2 is a metal plate on the ceiling; 3 is a long hose-like rubber cover.・1 is a large number +lll1 lined up in the rubber cover 3,
It is a group of rod-shaped optical fibers that transmit light well. 5 is foamed urethane rubber, which is filled in the gono and cover 3;
This is for positioning the light conductive member 4 made of the above-mentioned optical fiber.
このようにして形成された光伝導ヘルド６にり）力が作
用しないときは、光伝導部材４は各々の軸心が略−直線
になるように、きれいに並んでいるので、第３図の如く
、一方の端から発砲タイオード７によって光伝導ベルト
６内に光を矢印■方向に導入すると、他方の端から導入
した光の何割かが導出される。When no force is applied to the photoconductive heald 6 formed in this manner, the photoconductive members 4 are neatly lined up so that their axes are approximately straight, as shown in FIG. , when light is introduced into the photoconductive belt 6 from one end in the direction of the arrow {circle around (2)}, a percentage of the light introduced from the other end is extracted.
８は光を受ける特にポトトランジスフであり、この場合
は充分な光を受けるので、ポトトランシスフＩ３は側ン
し、検出回路９は光伝導ベルトに所定の押圧力が作用し
ていないことを感知する。なお、−１１３は電源の１極
である。Reference numeral 8 denotes a pottransistor that receives light, and in this case, it receives sufficient light, so the pottransistor I3 turns to the side, and the detection circuit 9 senses that a predetermined pressing force is not acting on the photoconductive belt. . Note that -113 is one pole of the power supply.
−力、第２図の如く、手灯１０か窓ガラス１の上端１．
−１と天井金属板２の間に挾まれると、光伝導ヘルド６

-1 and the ceiling metal plate 2, the photoconductive heald 6
The comb cover 3 is deformed and the urethane rubber 5 is compressed 2, so that a gap is formed between the optical fibers 4 at a portion of the cut portion 4a of the rod-shaped optical fibers 4 as shown in FIG.
従って、この場合は、第３図の発光ダイオード７により
導入された光は光伝導ベルト６内で大きく吸収され、ホ
トトランジスタ８がオンし５得ず、検出回路９が、押圧
力を感知することになる。Therefore, in this case, the light introduced by the light emitting diode 7 shown in FIG. become.
なお、光伝導部材４は一般に光ファイバーといわ１１て
いる２層ガラス構造のものでなくても良く、例えばクリ
スタルガラスで作った棒状ガラス材であっても良い。ヌ
、その断面は円形でなくても良く、だ円形や長刀形でも
良い。又、複数個を束ねたものでも良い。Note that the light-conducting member 4 does not need to have a two-layer glass structure, which is generally called an optical fiber 11, and may be a rod-shaped glass material made of crystal glass, for example. The cross section does not have to be circular, and may be oval or long sword-shaped. Alternatively, a bundle of a plurality of pieces may be used.
又、弾性部材３と５は一種類のゴム−Ｃ形成しても良い
。Further, the elastic members 3 and 5 may be formed of one type of rubber-C.
なお、本発明装置は自動車の天井部−扉開閉装置（ラン
ルーフ）、乗降用オートドアやエレベータ等にも使用で
きる。The device of the present invention can also be used in automobile roof-door opening/closing devices (run roofs), automatic entry/exit doors, elevators, and the like.
以上述べたように本発明においては、光を使用している
ので、保守が容易であり、コンパクトであって見ばえが
良好であり、又、線状に長く感知部分を配設することが
できるので、種々の押圧作用の検出に応用でき、装置の
安全性等を商めることかできるという効果がある。As described above, since the present invention uses light, it is easy to maintain, is compact and has a good appearance, and also allows the sensing portion to be arranged in a long linear manner. Therefore, it can be applied to the detection of various pressing effects, and has the effect of improving the safety of the device.
