Claims

[Scope of Claim for Utility Model Registration] In order to guide the tape from the cassette drawer part in the cassette loading part around the drawer cylinder, or vice versa, to guide the drawn tape to the cassette drawer part.
The cylinder is rotatably disposed on the chassis around the cylinder, and is rotated normally and reversed to a loading completion position or an unloading completion position by transmitting the rotational force from the gear means to teeth formed on the outer peripheral surface. In order to pull out the tape from the loading disk and the cassette drawer and guide it to the capsun side, and also to guide the pulled out tape to the cassette drawer, the rotational force from the gear means is applied and the loading ring is rotated in the correct direction. A device that is attached to the chassis so as to be slidable in a loading direction when the chassis is rotated and in an unloading direction when the chassis is reversed; a sliding plate device in which second sliding plates overlap, are engaged by an elongated member and a post, and are drawn toward each other by a spring, and the rotational force of the gear means is applied to the teeth of the second sliding plates; a sun gear that rotates as a sun gear; an internally toothed wheel gear that is spaced apart around the sun gear and whose internal teeth are oriented coaxially with the sun gear; A planetary gear is engaged with the planetary gear, a planetary wheel is rotatably coaxially supported by the bearing portion of the sun gear, and has a shaft at an eccentric position that rotatably supports the planetary gear, and the planetary wheel is engaged with the planetary wheel. The rotational force of the motor is rotatably supported at a fixed position so that it can be engaged or disengaged, and when in the engaged state, the rotational force of the motor is transmitted to the internal toothed wheel gear 7, and when it is in the disengaged state, the rotational force of the planetary wheel is transmitted to the internal gear. A wheel lock lever for switching the direction of transmission of the rotational force of the motor, and a rotational circumference of the loading ring, so that the rotational force of the motor is transmitted to the mode switching cam that allows rotation and is interlocked with the planetary wheel. When the loading ring comes to a predetermined position, which is the loading completion position, the roller at the tip of the rotation is moved to A ring lock is rotatably attached to the chassis so as to press it against the bottom, and the roller side is urged by a spring toward the rotating peripheral surface of the loading ring.
bar, and the wheel lock lever locks the planetary wheel, and the ring and lock lever are locked while the internal toothed wheel gear is loading the loading ring and slide plate device via the gear means. When the roller is within the ■-shaped range of the cam portion, the second
The post provided on the slide plate is the wheel lock lever.
A magnetic recording/reproducing device comprising means for setting the post movement trajectory of the sliding plate device so as to release the planetary wheel lock state in conjunction with each other.
