摘要： A vibration damping apparatus is provided with a main body, an elastic deformation section provided on the main body, and a projection which is made to follow the actions of the elastic deformation section and deform in every direction. The elastic deformation section acts as a damper to enable the vibration damping apparatus to dampen external vibrations transferred to the projection. For that reason, in recording/reproducing apparatus and other electronic apparatus on which the vibration damping apparatus is installed, it is possible to realize a reduction in the time needed to write to and read from a recording medium.

摘要： A recording/reproducing apparatus including a door member having its upper edge abutted against a lower edge of a forward stationary plate. The lower end of the stationary plate and the upper edge of the door member are formed with inclined surfaces that are inclined relative to the direction of insertion and detachment of a recording medium. When the recording medium is inserted, the door member is rotated by having its inclined surface thrust by the forward edge of the recording medium so as to be separated from the forward stationary plate to open the front side of the cartridge holder holding the recording medium to prevent intrusion of dust and dirt into the inside of the apparatus.
