Abstract
A camera has a bar code reader for reading a bar code from a roll film loaded therein. Bar code data read from the bar code is checked out whether it has a proper format or not. If the bar code data read from the bar code of the loaded roll film is proper, the bar code data is written in a nonvolatile memory, and the camera is set up in accordance with the bar code data. The bar code data of the nonvolatile memory is renewed each time proper bar code data is obtained. If the bar code data read from the bar code of the loaded roll film is improper, a display device displays film data represented by bar code data having been stored in the nonvolatile memory, along with an error indicia. If the displayed film data is invalid for the loaded roll film, the photographer enters film data of the loaded roll film through manual operation switches. Then, the camera is set up with the manually entered film data. If no film data is manually entered, the camera is set up in accordance with the displayed film data.
