Abstract

A light source is provided in the casing and emits a light beam for forming an image. A first sensor receives the light beam emitted by the light source and outputs a light reception signal. A cover opens and closes relative to the casing. A shutter prevents the first sensor from receiving the light beam when the cover is at an open position, and allows the first sensor to receive the light beam when the cover is at a closed position. A controller is configured to: execute a lighting process of lighting the light source; execute a first determining process of determining whether the light reception signal is outputted from the first sensor, in response to the lighting process; and determine that the cover is at the open position upon determination in the first determining process that no light reception signal is outputted.
