のである。EFFECTS OF THE INVENTION As described above, the ejecting motion converting mechanism of the present invention includes a linear motion member that has a passive part at one end and an actuating part at the other end and that linearly slides with respect to the chassis. Rotation about an axis having a passive portion on one side with respect to the rotation axis that engages with the driving portion of the linear motion member and on the other side with a driving portion for another member And a linear hinge member having an elasticity for integrally forming the linear motion member and the rotary member by connecting the vicinity of the driving part of the linear motion member and the vicinity of the passive part of the rotary member. The linear actuating force received by the moving member on its passive portion acts on the passive portion of the rotating member that engages with the driving portion of the linear moving member, causing the rotating member to rotate and rotating the rotating member. The other member is driven through the driving unit on the side different from the passive unit with respect to the shaft, and the hinge member serves as a linear motion member and a rotation member. By connecting them together and acting to return the linear motion member to its original position when the operating force on the linear motion member disappears due to its elasticity, the number of parts can be greatly reduced and production Since the workability in the process is improved and the use of grease is not necessary, there is no fear of occurrence of defects due to grease, and it is very useful for improving the quality of the cassette tape recorder. In particular, it is extremely advantageous in practical use in terms of cost reduction by reducing the number of parts and man-hours.
