PURPOSE:To prevent a set value from being changed by mistake, and to execute intended photographing by providing a click on a photographing information setting member, and inhibiting a release operation when the setting member is not positioned in the clock position. CONSTITUTION:Switches SWA, SWB are switched by being interlocked with a setting member 62, and the SWA is constituted of brushes 69, 71, lever 66 and a common electrode part pattern part 65, and the SWB is constituted of brushes 70, 71, the lever 66 and the pattern part 65. Also, the switches SWA, SWB detect an up-mode and a down-mode, supply a detecting signal to an input port of a CPU detects a driving direction of the member 62 by discriminating a phase of two signals whose phases are different from each other, and increases or decreases a set value. In this case, a click consisting of a recessed part 67 and a plate spring 68 is provided on the member 62. When the member 62 exists in other position than the click, the CPU inhibits a release operation. |
