PROBLEM TO BE SOLVED: To prevent dishonest actions using a clearance formed at the joint of a front surface door and a case body. SOLUTION: A first cover 26 is provided on the inner side of the respective side wall surfaces of an upper front surface door 4 and a lower front surface door 5. Inside the case body 3, a second cover 27 and a moving mechanism for moving the second cover 27 are provided corresponding to the first covers 26. When the lower front surface door 5 is closed, a first solenoid 42 starts an operation and moves the second cover 27 upwards. When the second cover 27 is moved upwards for a prescribed amount, a second solenoid 43 starts the operation and the second cover 27 is moved to the rear surface side of the case body 3. The tip 26b of the first cover 26 is inserted to the groove part 27a of the second cover 27 and the tip 27c of the second cover 27 is inserted to the groove part 26a of the first cover 26 respectively. Thus, the clearance 65 formed at the joint of the respective front surface doors 4 and 5 and the case body 3 is covered from the inner side and the insertion of a foreign matter is prevented.
