PROBLEM TO BE SOLVED: To provide a drawer-type door with an opening function or an auxiliary opening function similar as that of a rotary door, and to obtain the function without increasing magnetic force of electromagnetic device. SOLUTION: When an user performs the operation to open the drawer-type door, the operation is detected by an operation detecting means (S2), the electromagnetic device is acted (S3-S5), and the drawer-type door is energized in the opening direction. Thus the opening function or the auxiliary opening function similar to that of the rotary door can be achieved in the drawer-type door. Here, the electromagnetic devices are mounted on a part of the door and another part at an opposite side, and power distribution of the other electromagnetic device is implemented after a prescribed time from the power distribution to one of the electromagnetic devices on the basis of the detecting operation of the operation detecting means (S3-S5), thus the drawer-type door can be easily opened, and the magnetic force of the electromagnetic devices can be reduced so much.
