Abstract
An image recording apparatus having a sheet cartridge which stores therein an elongated photosensitive recording medium. A locking mechanism is provided selectively engageable with the sheet cartridge or a light shielding member which is positioned to prevent the cartridge from being exposed to light. A control means is provided to provide locking state of sheet cartridge or the light shielding member by controlling the locking mechanism to its locking position. This control is made in response to a signal indicative of the installation of the sheet cartridge at its predetermined position. The control means is also adapted to provide unlocking state of the sheet cartridge or the light shielding member by controlling the locking mechanism to its unlocking position. This control is made in response to a signal indicative of the complete discharge of the elongated photosensitive recording medium out of the sheet cartridge. The locking state is also provided in response to the signal indicative of the installation of the sheet cartridge plus a signal indicative of a complete closure of the light shielding member. The locking state is also provided upon complete sheet loading along a sheet path in the image recording apparatus.
