Abstract
In an ink jet type print recording apparatus, when a purge gear is driven and a purge pump arrives at its origin position, an origin mark of a pump cam gear presses a cam receiver of a first actuator so that a movement transmitting portion of the first actuator presses a movement receiving portion of a second actuator. With this operation, a shutter of the second actuator is moved out of a common sensor and the common sensor is switched on. Furthermore, when a print sheet is supplied to a platen roller, a sheet detector of the second actuator is pressed by the print sheet, whereby the shutter is moved out of the common sensor and the common sensor is switched on. Various operations are performed on the basis of signals from the common sensor.
