Claim:
An operating switch mechanism of a data recording and play device comprising: a first member comprising first and second cam surfaces with predetermined shapes; a second member comprising first and second rollers, energized by an energizing member toward the first and second cam surfaces, the second member sliding and transferring relatively to the first member along the first and second cam surfaces; and projected portions arranged to the first and second cam surfaces, wherein the first roller is abutted against the projected portion of the first cam surface so as to generate first reactive force in one direction along the slide direction, and the second roller is abutted against the projected portion of the second cam surface so as to generate second reactive force in the direction opposite to the one direction and holds the second member at a predetermined stable position, the operating switch mechanism further comprising: a sliding operating member that slides and transfers the second member by the sliding operation of an operator; and a third member that forms a part of the exterior of the data recording and play device and that can assemble the second member and the sliding operating member, wherein the first member is integrated to the main body of the data recording and play device, and the third member comprises an attaching portion that can be attached/detached to/from the main body of the data recording and play device or the first member in a state in which the second member and the sliding operating member are assembled.
