Are arranged at every angular interval of. A plurality of sets of spool chuck means including a movable chuck and a fixed chuck are attached to the turntable body.

Therefore, when the spool is concentrically supplied to the spool chuck means arranged corresponding to the chuck starting means, the solenoid of the chuck starting means is excited to push the movable chuck toward the spool. . For this reason, the spool is chucked by the spool chuck means, and the turntable is rotated in this state, and the spool is arranged corresponding to the spool positioning joint. In this spool positioning joint, the spool positioning claw abuts on the spool, and the support shaft of the spool positioning joint and the support shaft of the movable chuck are electromagnetically connected under the exciting action of the electromagnetic coil. Thereafter, the movable chuck is rotated. Then, when the spool positioning claw contacts the positioning groove of the spool, the rotation of the spool is stopped.

Next, the positioned spool is disposed on the film winding joint integrally with the spool chuck means. In this film winding joint, the electromagnetic coil is excited to electromagnetically connect the support shaft of the film winding joint and the support shaft of the movable chuck. Furthermore, by the spool rotating under the action of the motor,

In addition, for example, the relative linear movement distance of the first and second support means is reduced as compared with the case where the centering is performed by supporting the flange of the spool,
The speed of the entire film winding process can be easily increased.

The first supporting means connected to the spool rotating mechanism includes a holding shaft engaged with one end of the spool, and a spring for pressing the holding shaft toward the spool. This makes it possible to securely clamp both ends of the spool with a simple configuration. The holding shaft includes a cylindrical body that abuts one end of a spool, and a rotating pin that is disposed in the cylindrical body via a spring so as to be able to advance and retreat, and that is engaged with one end of the spool. Then, under the action of the spool rotating mechanism, the spool is integrally rotated via the rotating pin and the cylindrical body, so that the spool can be driven to rotate reliably and with high precision.

In addition, the rotating pin has a groove for fitting a key provided at one end of the spool,
The groove is provided with a tapered portion for guiding the key. For this reason, the rotating pin can be smoothly guided into the groove so that the rotating pin can be securely engaged with the spool, and the photographic photosensitive film is wound around the spool with high precision under the rotating action of the rotating pin. It becomes possible to do.

Further, the spool rotation mechanism advances and retreats with respect to the first support means via the cam means, and the spool rotation mechanism and the first support means are connected via a mechanical clutch. Therefore, a series of operations can be performed mechanically in accordance with various operation timings, and the entire operation can be easily speeded up.

Further, the rotation positioning mechanism for positioning the spool has a locking claw that engages with a step of the spool to stop the rotation of the spool, and the locking claw is swingable. It is supported by the arm member via a spring. Therefore, the positioning of the spool is easily performed with a simple configuration, and the locking claw does not interfere with the movement of the spool.

Further, the spool chuck means is provided with a pressing roller for pressing the end of the photographic film wound on the spool, and the pressing roller operates under the action of cam means interlocked with the rotation of the turntable. Is moved forward and backward with respect to the end of the photosensitive film. Accordingly, the pressing roller is mechanically driven via the cam means, and the timing adjustment in the sequence of the entire film winding process is easily performed.
