Electronic device with opening/closing door

Abstract

An electronic device with an opening/closing door of the present invention includes a device body in which an opening is defined, a shutter system capable of covering and exposing the opening, and a loosely fixing mechanism. The shutter system includes a door capable of moving back and forth between a closed position for covering the opening and an open position for exposing the opening, an arm swingably supported by the device body and having a front end engaging with the door, a motor for opening and closing the door by driving the arm, and a controller for controlling the operation of the motor. The controller is capable of switching the function of the motor between an electric motor and an electric generator. The loosely fixing mechanism is linked to the arm of the shutter system, and loosely fixes the arm when the door is placed at the open position, while loosely fixing the arm when the door is placed at the closed position. The controller causes the motor to function as an electric motor in the process of opening and closing the door, while causing the motor to function as an electric generator when the door is loosely fixed at the open position or at the closed position.
