Image recording apparatus

摘要

An image recording apparatus includes a cartridge mounting portion including an optical detector comprising a light-emitting portion configured to emit light and a light-receiving portion configured to receive the light emitted from the light-emitting portion. The light-receiving portion is configured to output a signal depending on an intensity of light received by the light-receiving portion. The image recording apparatus also includes an ink cartridge including a projecting portion configured to act on the light emitted from the light-emitting portion, causing the intensity of light received by the light-receiving portion to change, during an insertion of the ink cartridge into the cartridge mounting portion. The image recording apparatus further includes a controller configured to allow ink to be consumed in the image recording apparatus, based on a change of the signal output from the light-receiving portion.
