A control device permits execution of a print process on condition that an object sensor detects an object at a detection position. A switch mechanism, in accordance with a release operation, releases an interlock between a first displacement member and a closing operation of a cover portion. In a state where a second displacement member is located at an actuation position, a detected portion is located at the detection position. When the second displacement member is located at a retreat position, a first contact portion is not in contact with the cover portion. When the cover portion is closed, the cover portion displaces the second displacement member from a standard position to an actuation position. When the first displacement member is displaced from a first relay position to a second relay position, the first displacement member displaces the second displacement member from the standard position to the retreat position.
