PURPOSE:To obtain an automatic ticket examination machine with safety even when an accident occurs by providing a first pressing means which moves a door element to a position to constrain, and a second pressing means which releases an engaging state with a rocking arm. CONSTITUTION:The rocking arm 4 is turned by pressing a lock bar 5 from the outside, and the door side protrusive terminal engaging part 34 of the arm is fitted in the recessed part 23 of the door element 3. Thereby, a retainer plate 6 is released, and it is turned in a direction of arrowhead B by the pressing force of a retainer spring 16. Thus, a door 1 is constrained via the door element 3 and the rocking arm 4. Also, the retainer plate 6 can be moved by applying the function of a couple of forces in a direction of arrowhead C to the retainer plate 6, which releases constraint on the rocking arm 4, and also, the fitting state of the door side protrusive terminal engaging part 34 of the rocking arm 4 with the recessed part 23 of the door element 3 can be released. Furthermore, a release solenoid 8 releases the door 1 set at a locked state by electric control. |
