PROBLEM TO BE SOLVED: To easily switch an automatic ticket checking on machine to be exclusive for entrance or exit by vertically dividing a housing forming the main body of the automatic ticket checking on machine, providing a hook to be turnable from the outside on its one side and providing the lock element of hook on another side. SOLUTION: Upper and lower housings H1 and H2 are freely turnably connected by a turn table mechanism provided at the central part of their divided plane, and when a lock mechanism R is unlocked, the upper casing H1 can be turned by half through this turn table mechanism. The lock mechanism R is provided with a rotary shaft 30, which can be turned from the outside of main body by a 10-yen coin or the like, and hooks 32a and 32b fixed on both the sides of the rotary shaft 30 are turned at the same angle by the turns of the rotary shaft 30. When the top ends of hooks 32a and 32b are turned to the side of lower housing H2 by the rotary shaft 30, lock elements 34a and 34b provided on a frame F1 of the lower housing H2 confronted with these hooks 32a and 32b are respectively engaged with the hooks 32a and 32b and turned to locked states and the locked states are stably held by a coil spring provided at one hook 32a. |
