Safety Standard of Machinery, Equipment and Tools Article 12-4
A laser-sensitive safety device for a press brake shall have the following performances:1. A construction can make the slider stopped when it detects a body part shading the light and the slider has a risk to catch the body.2. A construction can make the slider speed reduced to be less than 10 millimeters (hereinafter referred to as the low closing speed) when it detects a body part or a workpiece shading the light or the slider is asked to keep moving in closing action even the slider having reached a set position.A laser-sensing safety device can be applied to a press brake complying with the following provisions:1. A construction can adjust the slider to the low closing speed when it is in closing move.2. A construction can make the slider not activated in the low closing speed except it is operated at the operating portion.The detecting construction of the laser-sensitive safety device for a press brake shall have the following performances:1. The emitter and receiver is provided at the location where a body part may be caught by the slider. If the slider of the press brake is a dropping type, the construction of the detector has the motion in conjunction with the slider motion.2. A construction can make detecting function invalidated while the slider is in closing motion and the low closing speed.

摺床用雷射感應式安全裝置,應具有下列性能:
一、具有檢出機構,且於身體有被夾之虞者,遇身體之一部將光線遮斷時能檢出,並使滑塊等停止作動之構造。
二、滑塊等在閉合動作中,檢知身體之一部或加工物遮斷光線,或滑塊等到達設定位置仍須使滑塊等繼續動作者,具有能將滑塊等之移動速度降為每秒十毫米以下(以下簡稱低閉合速度)之構造。
雷射感應式安全裝置,適用於符合下列規定之摺床:
一、滑塊等在閉合動作時,具有可將滑塊等之速度調至低閉合速度之構造。
二、使滑塊等在低閉合速度動作時,具有非在操作部操控,無法作動滑塊等之構造。
摺床用雷射感應式安全裝置之檢出機構,應具有下列性能:
一、投光器及受光器須設置在能檢知身體之一部可能受滑塊等夾壓之位置;摺床採滑塊等下降動作者,其檢出機構具有與滑塊等動作連動之構造。
二、滑塊等在閉合動作中,且在低閉合速度時,具有得使檢知機能無效化之構造。
