When a recording medium is inserted into an insertion part, a locking part of a pull-in member locks a concave part of the recording medium because a pressed part is pressed to move a moving member. Simultaneously, a first switching member is switched, and a cam member rotates to move a power transmission means into the inside of an apparatus (Y1-direction). Thereby, since the moving member having the pull-in member mounted thereon also moves, the recording medium can be carried into the inside of the apparatus. If the recording medium is abnormally orientated, the locking part can lock the concave part. Therefore, the recording medium can be prevented from being carried into the inside of the apparatus.
