Camera reading information applied to a film unit

A camera adapted to be loaded with a film unit having film including a plurality of frames, a cartridge containing said film therein and information-recorded means, said camera including:

• first recording means for recording on said information-recorded means information relating to photographed frames indicative of which of the frames of said film is a photographed frame;
• first reproducing means for reproducing from said information-recorded means said information relating to photographed frames recorded by said first recording means;
• second recording means for recording on said information-recorded means discriminative information indicative of whether the reading-out of said information relating to photographed frames by said first reproducing means is necessary;
• second reproducing means for reading out said discriminative information recorded by said second recording means from said information-recorded means;
• film feeding means for feeding said film;
• and
• control means for causing said first recording means to record on said information-recorded means information on the basis of a feeding direction by said film feeding means.

A recording method of a camera capable of loading therein a film unit which has a film including a plurality of frames, a cartridge and an information-recording portion, comprising:

• recording on said information-recording portion first information relating to photographed frames indicative of which of the frames of said film is a photographed frame;
• recording on said information-recording portion second information indicative of whether the reading-out of said first information is necessary;
• reading out said second information from said information-recording portion when said film unit is loaded into said camera;
• and
• reproducing from said information-recording portion said first information when the read out second information indicates that reading-out of said first information is necessary and not reproducing from said information-recording portion said first information when said read out second information indicates that reading-out of said first information is unnecessary.

A recording method of a camera capable of loading therein a film unit which has a film including a plurality of frames, a cartridge and an information-recording portion, comprising:

• recording, on the basis of a film feeding direction, on said information-recording portion first information relating to photographed frames indicative of which of the frames of said film is a photographed frame;
• reproducing from said information-recording portion said first information;
• recording on said information-recording portion second information indicative of whether the reading-out of said first information is necessary;
• and
• reading out said second information from said information-recording portion when said film unit is loaded into said camera.

A device adapted to be loaded with a film unit having film including a plurality of frames, a cartridge containing said film therein and information-recorded means, said device including:

• first recording means for recording, on said information-recorded means information relating to photographed frames indicative of which of the frames of said film is a photographed frame;
• first reproducing means for reproducing from said information-recorded means said information relating to photographed frames recorded by said first recording means;
• second recording means for recording on said information-recorded means discriminative information indicative of whether the reading-out of said information relating to photographed frames by said first reproducing means is necessary;
• second reproducing means for reading out said discriminative information recorded by said second recording means from said information-recorded means;
• and
• control means for operating said second reproducing means when said film unit is loaded into said device, and operating said first reproducing means when said discriminative information read out by said second reproducing means indicates that the reproducing of said information relating to photographed frames is necessary, and saving the operation of said first reproducing means when said discriminative information indicates that said reproducing is unnecessary.
