Abstract
A negative carrier for a photographic printer, which is installed on a photographic printer for print-exposing an image on a negative film onto a photosensitive material, and which effects the positioning of the negative film during print-exposure of the photosensitive material. The negative carrier includes a sensor disposed in a transporting passage of the negative film so as to detect information concerning the negative film; and a controlling device for determining the presence or absence of the negative film over the sensor on the basis of a detection signal from said sensor, and for calibrating the sensor if it is determined that the negative film is absent. The sensor is prevented from being calibrated erroneously in a state in which the negative film is present over the sensor, thereby facilitating the calibration of the sensor.
