Apparatus having a film condition judging device

An apparatus having a film condition judging device which judges a used condition of a film based on data obtained by reading out bar codes of a bar code disk equipped on a film cartridge, wherein the bar code disk is initially stopped at a predetermined rotational position in response to the used condition of the film, comprises:

• a reading out sensor which reads out the bar codes of the bar code disk;
• a motor rotation amount detector which detects a rotation amount of a motor which drives the bar code disk to rotate;
• an inclination detector which detects output from the reading out sensor at a plurality of times during rotation of the bar code disk and detects inclination changes of the sensor's output based on the sensor's detected output and pulse numbers which are detected by the motor rotation amount detector;
• a counter which counts the sensor's output as a correct signal when the inclination which is detected by the inclination detector is a prescribed value or more, and on the other, does not count the sensor's output when the inclination is less than the prescribed value;
• and,
• a judging device which judges the used condition of the film based on a counted value by the counter.

• a reading out sensor which reads out the bar codes of the bar code disk;
• a counter for counting the sensor's output;
• a detector which detects a non-indication zone of the bar code disk based on a bar code detected signal which is output from the reading out sensor;
• and, a judging device which judges the used condition of the film based on number of the bar codes counted by the counter until a first non-indication zone is detected after a motor which drives the bar code disk is ON, and confirms whether the judgment result is correct based on number of bar codes counted by the counter until a second non-indication zone is detected.

• a reading out sensor which reads out the bar codes of the bar code disk;
• and
• a microcomputer which carries out an inclination detection in which output from the reading out sensor is detected at a plurality of times during rotation of the bar code disk and inclination of the rising/falling of the output is detected based on the sensor's output and intervals between the detected times;
• a count in which the sensor's output is counted as a correct signal when the detected inclination is a prescribed value or more, and is not counted when the inclination is less than the prescribed value;
• and a judgement in which the used condition of the film is judged based on the counted value.
