Are provided separately in the vertical direction, a plurality of light beams from the floodlight are provided in the vertical direction and the distance between the light beams in the left-right direction is set to be smaller than the width of the hand, and the light beams on both left and right sides are made visible. It will be.
（実施例） 以下、この考案の実施例を図面に基づいて詳細に説明
する。(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
第１図を参照するに、プレス機械１はフレーム３の上
部にスライド５が上下動自在に設けられ、そのスライド
５の下方にボルスタ７が設けてある。前記プレス機械１
の操作側すなわち前面側（第１図において左側）には、
光線式安全装置９である投光器11と受光器13が設けてあ
り、その投光器11と受光器13はフレーム３の左右の側壁
に設けた支持板15に支承されたブラケット17に係止して
ある。Referring to FIG. 1, in the press machine 1, a slide 5 is provided on an upper portion of a frame 3 so as to be vertically movable, and a bolster 7 is provided below the slide 5. The press machine 1
On the operating side, that is, on the front side (left side in FIG. 1),
A light source safety device 9 is provided with a light transmitter 11 and a light receiver 13. The light projector 11 and the light receiver 13 are locked to brackets 17 supported by support plates 15 provided on the left and right side walls of the frame 3. .
前記投光器11と受光器13間を走る複数本の光線19Aの
うち、所定本数（例えば左右端）の光線19Bのみを可視
光である着色光線を採用する。なお着色光線の色は何色
でも自由である。Among a plurality of light rays 19A running between the light projector 11 and the light receiver 13, only a predetermined number (for example, right and left ends) of the light rays 19B is a colored light ray which is visible light. The color of the colored light beam can be any color.
上記構成において、例えば第６（Ａ），（Ｂ）図およ
び第７図に示すごとく、人間の手の厚みH1は手の幅L1よ

のが一般的である。このため、投光器11、受光器13を上
下方向に取付け、光線19A,19Bを上下に走らせて幅方向
を検出するようにしたので、不感帯の影響を受けにく
く、多くの場合必ず光線19A,19Bを遮光するので、誤っ
て手などを挿入しても確実に検出することができる。In the above structure, as shown in FIGS. 6 (A), (B) and FIG. 7, the thickness H 1 of the human hand is smaller than the width L 1 of the hand, and even if the processing material W is used, the plate thickness H 2 Generally, the board width L 2 is wider. Therefore, the light emitter 11 and the light receiver 13 are attached in the vertical direction, and the light beams 19A and 19B are run vertically to detect the width direction. Since the light is shielded, it is possible to reliably detect even if a hand or the like is inserted by mistake.
また、従来型の場合に不感帯に入ってしまった材料Ｗ
等が、動いたり、傾むいたりした時に発生するチャタリ
ング現象を減少させることができる。In addition, the material W that has entered the dead zone in the case of the conventional type
It is possible to reduce the chattering phenomenon that occurs when the subject moves or leans.
更に、例えば光線の左右側のみを可視光である着色光
線19Bとすることにより、作業者に対して光線式安全装
置９の防護範囲を明確かつ容易に認識できると共に、光
線の有無すなわち安全装置が作用状態にあるか否かの識
別ができ安全性の向上を図ることができる。Further, for example, by making colored rays 19B that are visible light only on the left and right sides of the light beam, the operator can clearly and easily recognize the protection range of the light beam safety device 9, and the presence or absence of the light beam, that is, the safety device It is possible to discriminate whether or not it is in an operating state and improve safety.
なお、光線式安全装置９がプレス機械１の前面側左右
方向に設けられたものに対しても可視光線19Bを採用す
ることにより、例えば上限、下限の光軸を着色すること
で防護高さを認識することができ安全性を増すことは勿
論である。Even if the light beam safety device 9 is provided on the front side of the press machine 1 in the left-right direction, by adopting the visible light beam 19B, for example, by coloring the upper and lower optical axes, the protective height is increased. Of course, it can be recognized and safety is increased.

ある。As can be understood from the above description of the embodiments, in short, the present invention is provided with the light beam safety device (9) in front of the operating region of the slide (5) which is vertically movable in the press machine (1). The light emitter (11) and the light receiver (13) are vertically separated from each other, a plurality of light rays (19A) from the light emitter (11) are vertically provided, and the distance between the light rays (19A) in the left and right direction is set. It is provided at intervals smaller than the width of the hand (L 1 ), and the light rays (19B) on both left and right sides are made visible.

線19Aは上下方向に設けてあり、かつ左右方向の間隔は
手の幅L1の間隔よりも小さく設けてある。そして、左右
両端側の光線19Bは可視光線にしてある。As is apparent from the above configuration, in the present invention, the plurality of light beams 19A from the projector 11 in the light beam safety device 9 provided on the front side of the operation area of the slide 5 in the press machine 1 are provided in the vertical direction, In addition, the distance in the left-right direction is set smaller than the width L 1 of the hand. The light rays 19B on the left and right ends are visible rays.
したがって、本考案によれば、スライド５の作動領域
に手を近づけようとすると、かならず光線19Aを遮断す
ることになり、確実な安全性が確保できるものである。Therefore, according to the present invention, when the hand is brought close to the operation area of the slide 5, the light ray 19A is always blocked, and reliable safety can be secured.
また、左右両端側の光線19Bは可視光線に設けてある

識することができるものである。Further, since the light rays 19B on both the left and right ends are provided as visible rays, it can be confirmed whether the light beam safety device 9 is ON or OFF by checking whether or not there are visible rays on both ends. In addition, when visible light cannot be visually inspected despite being ON, it can be detected that the projector 11 has a failure. That is, when visible light is not visually observed, it can be recognized as abnormal (including OFF).
さらに、両端側の可視光線によって、光線式安全装置
