<p>PURPOSE:To extremely improve the assembling efficiency by extending the guide holes up to the end face of a side frame for production of the open grooves and putting a guide pin through these open grooves to set a cassette holder into a frame. CONSTITUTION:A frame 10 having a U-shaped section is produced by a press molding process, and the guide holes 11a and 11b are formed in a side frame 10b together with the open grooves 12a and 12b formed continuously to both holes 11a and 11b at a reinforcing bent part 13. A cassette holder 3 can be set into the frame 10 in an extremely simple way, that is, the holder 3 is just engaged to the frame 10 via an existing slip-out preventing means after the holder 3 is put into the grooves 12a and 12b.</p> |
