Abstract
An image recording apparatus forms the image by using a photo-sensitive sheet accommodated in a cartridge, one side of which has a bar code attached. In this recording apparatus, a remaining amount of the sheet in the cartridge at a given time is calculated by substracting a used amount of the sheet detected by a rotary encoder installed on a motor shaft of a sheet feeding device from a total amount of the sheet detected by reading the bar code through a bar code reading device, and is displayed on a display. And, this recording apparatus corrects the remaining amount of the sheet in the cartridge based on a rewound amount of the sheet detected by the rotary encoder when a single copy mode is selected. Further, the apparatus displays copyable numbers according to the remaining amount of the sheet based on a copy size set. Therefore, it is possible by the recording apparatus to precisely recognize the remaining amount of the sheet in the cartridge at an arbitrary time and a timing for exchanging the old cartridge for a new cartridge.
