Camera with bar code reader

A method of setting up a camera by use of a bar code provided on a roll film, the method comprising the steps of:

• rotating a motor in a first direction to cause a take-up spool to rotate so as to move the roll film in a film winding direction while a rewind shaft is allowed to rotate freely;
• reading a bar code of a roll film presently loaded in the camera while a first frame recording area of a film-strip of the presently loaded roll film is transported by the take-up spool to an exposure position behind an exposure aperture;
• checking if bar code data read from the bar code of the roll film is proper;
• writing the bar code data in a nonvolatile memory when the bar code data is proper, the nonvolatile memory being renewed each time proper bar code data is obtained;
• and
• if the read bar code data is proper, setting up the camera in accordance with the bar code data read from the bar code of the presently loaded roll film;
• if the read bar code data is improper, rotating the motor in a second direction to cause the rewind shaft to rotate so as to move the roll film in a rewinding direction while the take-up spool is allowed to rotate freely, then rotating the motor in the first direction to cause the take-up spool to rotate so as to move the roll film in the film winding direction while the rewind shaft is allowed to rotate freely, reading the bar code a second time;
• if the bar code data is read the second time and is determined to be improper, setting up the camera in accordance with bar code data stored in the nonvolatile memory.

• if the bar code data is read the second time and is determined to be improper and a mode selector is set to a first mode, allowing a user to choose between bar code stored in the nonvolatile memory and data entered through a manual data entry device;
• if the bar code data is read the second time and is determined to be improper and a mode selector is set to a second mode, substituting the bar code data stored in the nonvolatile memory for the read bar code data;
• and
• if the bar code data is read the second time and is determined to be improper and a mode selector is set to a second mode, requiring the user to enter data using the manual data entry device which is used to replace the improper read bar code data.
