    摘要： According to an aspect of the invention, an image forming apparatus includes an apparatus body, a sound absorbing device utilizing a Helmholtz resonator, and a hinged exterior cover operable to open and close relative to the apparatus body. The hinged exterior cover is a hinged cover configured to pivot about a pivot shaft arranged at a lower end portion of the hinged exterior cover. At least a part of the hinged exterior cover has a multiplex structure made by overlaying a plurality of plate-like members on one another. The sound absorbing device is formed by utilizing space between two plate-like members of the plurality of plate-like members making up the multiplex structure as a cavity of the Helmholtz resonator.

    摘要： A holding mechanism for an opening and closing detection device includes a cam, a torsion coil spring, and a pressing member. The cam is rotatably supported in a housing. The torsion coil spring is attached to the cam or an inside of the housing and includes two ends extending in two directions. The pressing member biases one end of the two ends of the torsion coil spring and bring the other end of the two ends of the torsion coil spring into contact with the cam to apply a load to the torsion coil spring. The pressing member is attached to an outside of the housing while biasing the other end of the two ends of the torsion coil spring through an opening of the housing.
