摘要： A mounting device on a camera has a mounting member to fit with an accessory so as to mount the accessory on the camera by sliding it. The mounting member which is molded out of plastic in one piece has eaves-like portions overhanging from an upper portion thereof in opposite directions intersecting perpendicularly to a mounting direction of the accessory, thus having a generally T-shaped cross section. The mounting member has a groove running in the mounting direction at a top central portion for receiving a projecting portion of the accessory so as to determine a horizontal (lateral) position of the accessory relative to the camera. The eaves-like portions receive mating members of the accessory thereunder so as to determine a vertical position of the accessory relative to the camera. The groove is narrower at the front end than at the back end where an insertion opening for the accessory mounting is provided, where the projecting portion of the accessory is similarly narrower at the front end from which the accessory is inserted into the groove.
