PURPOSE:To eliminate malfunction and to enable satisfactory processing of a photosensitive body by detecting the information on the processing time which varies with various photosensitive bodies to be processed. CONSTITUTION:A sensor to determine developing time is constituted by disposing projections S1-S3 indicating the kind of a roll film F on the outside wall of a housing 32 and providing a microswitch to detect said projections to the inside wall surface of a body 11 facing the housing 32 when the housing 32 is loaded. The information of whether the film F to be developed is color or black and white as well as the length of the film F, etc. is detected by the sensor and the developing time is determined therefrom. As a result the automatic setting of the developing time meeting the kind of the film F is made possible simply by loading the film F or the housing 32. |
