Separation and opening between the front door 3 and an outer frame 2 and the separation and opening between the rear mechanism unit 5 and the front door 3 are restricted by a locking device 900. Base plate boxes 411, 401 incorporating a discharge control base plate and a power source base plate, respectively, are displaced on the rear face plate of a resin base 550. When the separation and opening are restricted, the restricting part 443 of a door body is located on the left side of the side wall of each of the base plate boxes 401, 411 as viewed from rear, thereby restricting the slide movement of the base plate boxes 401, 411 in the directions |
