Document Type and Number:
Japanese Patent JP2015027895
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve detection precision and safety by further making detection of a string-like foreign substance easier.SOLUTION: On a door-end rear surface side of doors 3, 4, a swing bar is provided along height direction, and a micro switch is provided for detecting the displacement of swing bars 18, 19. The swing bars 18, 19 are rotatably attached around hinge pins 22, 29 vertical to the doors 3, 4, and based on the rotational operation, reciprocation is made in the opening/closing direction of the doors 3, 4. Thus, when an entrance is totally closed by the doors 3, 4, the swing bars 18, 19 of the doors 3, 4 are set so that they overlap each other in the direction perpendicular to the surfaces of the doors 3, 4.
