<p>PURPOSE:To transport correctly and smoothly by stopping a conveyor at a proper position with a position detector, storing the position as an expected correction and fitting/removing position, and performing the subsequent control in the control device of a video cassette conveyor, etc. CONSTITUTION:The expected fitting/removing position of each reproducer 8 in reference with a reference point C where a conveyor 5 is to be stopped is stored in a controller 4 as the number of drive pulse C0 of a step motor 7 required for the shift from the reference point C. Then, the conveyor 5 is shifted to the expected fitting/removing position and is stopped. At this time, the motor 7 is correction-driven based on the relative position between a photosensor 11 and a shutter 12 to perform the position correction properly. Next, the expected fitting/ removing positions for other reproducers 8 are corrected likewise. Subsequently, the predetermined time control is performed based on this correction result. According to this constitution, the transportation can be performed smoothly, correctly, and automatically even if the stop position is changed with the passage of time.</p> |
