PURPOSE:To improve the reliability of a preventing machanism for door opening including a latch while facilitating its handling, by providing the mechanism to a main-body function part and also by providing a solenoid as its driving source to a fixed part. CONSTITUTION:Solenoid 15 is fitted to the fixed part of operation button 8 via metallic fitting 16 and reset plate spring 12 and operation button 8, latch 9, and stop plate 26 are fixed to frame body 1 of the main-body function part. The tip of armature 19 is positioned in groove part 27 of latch lever 23. When the door opening-closure preventing mechanism is not in operation, latch 9 engages latch lever 23 because solenoid 15 releases armature 19, so pushing the operation button releases the door. When the preventing mechanism for door opening is in operation, the solenoid is energized to suck armature 19 and then latch lever 23 is drawn downward to disengage from latch 9, leaving the door closed. Thus, the reliability can be improved. |
