ABSTRACT:
Two bar code sensors are disposed at opposite sides of a passage of a photographic film, each bar code sensor having first and second photosensor arrays. The first and second photosensor arrays are located at the passages of the clock track and the data track, respectively, along a line perpendicular to the transportation direction of the photographic film. The DX bar code data and frame number bar code data are discriminated automatically based on the bar code data configuration read out with the bar code sensor units. The setting condition of the photographic film is detected, also based on the bar code data configuration. In case of an abnormal state of the setting conditions, an alarm display is output. The bar code data is written in a memory when the data change, or synchronously with reading the clock track of the DX bar code. The number of a frame set at the film mask is calculated by measuring the feed amount of the read-out frame number bar code.
