ABSTRACT:
A door assembly for a device for driving a recording medium has a panel defining an opening through which the device can be loaded with a recording medium or unloaded. A door is rotatably supported on the inside of the panel. A pair of springs are associated with the door for urging it in a direction in which it is rotated to close the opening. A shutter is slidably supported on the inside of the panel for closing the opening when the device has been loaded with a recording medium. A pair of levers are rotatably supported on the panel and are adapted for simultaneous rotation. Each lever has a first end connected to the shutter and a second end which is engageable by the recording medium for rotation in a direction in which its first end is rotated to move the shutter in a first direction in which it closes the opening. Another spring is connected between the levers for urging the first ends thereof in a direction in which they move the shutter in a second direction in which it clears the opening.
