Abstract
An image recording apparatus having a sheet cartridge in which a rolled photosensitive recording medium is accommodated. The sheet cartridge has a sheet retaining device for preventing the recording medium from being retracted into a cartridge casing. The retaining device also provides a light shielding member. The image recording apparatus also includes structure for preventing the cartridge from being removed in a case where a residual recording medium is still rolled in the cartridge casing. The image recording apparatus is provided with a wiper member for removing dusts deposited on a surface of a feed roller. Further, a sensor element is provided for detecting non-rotation of a takeup shaft or a slack of the recording medium.
