SAFETY APPARATUS |
摘要 |
The present invention uses a sensor (10n SIMILAR 15n, 16) which transmits detection data of an object (M) by the decrease of an output signal energy, as a sensor for detecting people, and a sensor which transmits the detection data of the object (M) by the increase of the output signal energy, as a sensor (21 SIMILAR 26) for detecting a work. Driving of a mechanical movable portion is permitted only when the logical sum of the outputs from both sensors is a logical value 1 corresponding to the high energy state. In this way, the present invention provides a safety apparatus which has a high fail-safe function and can reliably secure safety of operators. |
