(4) An operation command is issued to a block other than the junction block. → (5) The stop position of the junction carrier deviates from a specified position (at this time, the mechanical part of the other block has already started moving) → (6) As described above. It is detected by a sensor or the like that the upper control board 60a has shifted from the stop position. → (7) Upper control board 6
0a issues an operation stop command to a moving part (mechanical part of the other block) in the system.

As described above, the control method using a sensor or the like provided at the junction requires a large amount of time until it is determined that the stop position of the junction carrier is abnormal, and the procedure for stopping is very difficult. It gets complicated.

The present invention has been made in view of the above points, and an object of the present invention is to provide an apparatus having a recording medium moving means capable of detecting a stop position shift of a junction conveyance body correctly and with a simple control procedure.
