SIMPLE PHOTOGRAPH PRINTER

PURPOSE:To surely attain reading by accompanying with the position displacement of the width direction of tracks and selecting each fine light receiving part of a line-shaped optical sensor which reads printing process information recorded in two or more tracks by means of an information processing part. CONSTITUTION:The line-shaped optical sensor 30 made up of the plural fine light receiving parts in one line is in a position facing the data track 21 and a timing track 22 of an original film 10 in the carrying path P of the original film 10 and arranged to extend along a direction B vertical to the carrying direction A of the original film 10. Each fine light receiving part simultaneously reads the printing process information recorded in the data track 21 and the timing track 22 in a state where reading positions in the carrying direction A of the original film 10 agree with high accuracy. Thus, reading of the printing process information can surely be attained by simple constitution.
