Attempts have been made to open the insertion slot on the same front panel.

[0004]

By the way, when two insertion ports are opened in the same front panel, if door members are individually provided for each of the insertion ports, when one door member is opened and closed, The problem of interference with the other door member occurs. For this reason, it is necessary to dispose both door members sufficiently apart from each other so that they do not hit each other. However, as is well known, the space on the front surface of the front panel is limited, and the two door members are provided in this limited space. In order to dispose the members, the outer dimensions of each door member had to be reduced, and operability had to be sacrificed.

[0005]

According to the present invention, when one door member is opened, the door member is overlapped with the other door member in a plane. With this configuration, when one of the door members is opened and closed, the door member does not collide with the other door member. Therefore, the degree of freedom in design including the size and arrangement position of both door members is improved, and operability is improved. It is possible to realize a door opening / closing device that is excellent in quality.
