PURPOSE:To connect surely a recording medium and a device-side connecting part by providing a cam member, which is driven while interlocking with opening/closing of a bucket, and a center core pushing member driven with the cam member. CONSTITUTION:In the state where a bucket 36 is opened, a magnetic sheet bag 21 is loaded to the bucket 36. In the process where the bucket 36 is closed, a cam member 55 is operated, and the member 55 drives a center core pushing member 63, and the member 63 presses a center core 23 of a magnetic sheet 22 in the bag 21 to a driving shaft 31. The shape of the member 55 and the operation timing are selected properly to drive the member 63 at a required timing. Thus, the recording medium is connected surely to the device-side connecting part in relation to the essential operation for loading the recording medium to the device.
