Abstract

PURPOSE:To eliminate the troubles of key operations and to improve the operability of a camera by attaching a bar code at a prescribed part of the camera for setting the operation modes, etc., of the camera, recognizing the bar code, and setting an operation mode, a necessary variable, etc., which are prescribed by the bar code. CONSTITUTION:A bar code member 20 includes a bar code part 20A and a caption part 20B and can be freely bent at the boundary between both parts. When a time setting mode is shown at the part 20B, for example, a bar code is shown at the part 20A against the time setting mode. In other words, the member 20 unifies an instruction manual and a bar code and also can be firmly set into the camera body owing to its flexibility by pushing the level difference parts 21 and 22 into a storing part 13. As a result, the operations including the transition of key modes, etc., can be quickly carried out with no key input operation of the camera. Furthermore the number of keys can be decreased so that the misoperations of keys are eliminated and the operability of the camera is improved.
