SIMPLE PHOTOGRAPH PRINTER

PURPOSE:To set appropriate printing process conditions with high probability by setting the printing process conditions based on two or more sets of agreed printing process information which are read by means of a sensor. CONSTITUTION:An original film 10 is normally carried from an edge part along a longitudinal direction on a carrying path P by means of a normal carrying part. When a data track 21 and a timing track 22 of the original film 10 pass right above the sensor 30, reading operation is started by sequentially reading the printing process information. The reading signal of the sensor 30 is sent to an information processing part and the normal carrying part normally carries the original film 10 and the reading operation is continued until read values agree at least twice or more. When at least two or more sets of read values agree, the printing process conditions re set based on said agreed read values. Thus, the appropriate printing process conditions can be set with high probability by simple constitution.
