Abstract
A door mechanism comprises a frame having an insertion port and first and second door panels. The first and second door panels have respective pivot shafts rotatably connected to the frame. These door panels are supported by the frame such that they can swing about the respective pivot shafts between closed positions in which they close the insertion port, and open positions in which they open the insertion port. The first and second door panels are swung apart in opposite directions when they are shifted from the respective closed positions to the respective open positions. The first and second door panels are urged by a spring toward the respective closed positions. The spring has a first coil section mounted on the pivot shaft of the first door panel, a second coil section mounted on the pivot shaft of the second door panel, arm sections each extending from one end of a corresponding one of the first and second coil sections and urging the first and second door panels toward the respective closed positions, and a connecting section bridging another end of each of the first and second coil sections.
