Claims

[Claims for Utility Model Registration] Cassette holder transfer means are provided on both sides of the cassette holder in the transfer direction, and have gear portions that mesh with the gears of the synchronous shaft. One of these transfer means is the drive side, and this drive Of the gear portions of the side transfer means, a portion corresponding to the position where the cassette holder reaches the position immediately before mounting is missing, and the drive side transfer means has an intermediate gear coaxially arranged to transmit the rotation of the cassette loading motor. and an elastic body is interposed between the drive-side transfer means and the intermediate gear to provide elastic force against rotation in both forward and reverse directions, and the intermediate gear A cassette mounting device for a magnetic recording and reproducing apparatus, characterized in that the gear is provided with a partial gear that meshes with the gear of the synchronizing shaft at the missing portion of the gear portion of the drive-side transfer means.
