PURPOSE:To electric discharge the electric charge of a main capacitor in order to secure the safety in work when a disposable camera equipped with a flash lamp which is recovered is disassembled. CONSTITUTION:A cover body 8 which can be freely demounted is installed on a part of a camera outside box 1, and a projection which holds the contact point of a switch SW3 which is connected in series with an electric power source circuit and has an always opened contact point, into closed state, and holds the contact point of a switch SW4 which is connected in series with an electric discharge circuit for a main capacitor and has an always closed contact point, into opened state, in the state where the cover body 8 is installed on the camera outside box 1, is installed. When the cover body 8 is demounted, the switch SW3 is opened, and the SW4 is closed, and the electric charge is suspended, and a main capacitor is electric-discharged. |
