Abstract
A tape conveying device has a loop bin which accomodates a meandering endless tape. The tape loop bin comprises a tape drive means, a tape running speed detecting means for detecting the running speed of the endless tape from the operating condition of said tape drive means, a tape conveying means for conveying the endless tape to meanderingly run in said loop bin to an exit from said loop bin, and a tape conveying control means complying with a running speed signal of the endless tape received from the tape running speed detecting means. Endless tape fed into the loop bin by a tape driving means travels toward an outlet from the loop bin. The tape conveying means is controlled to comply with a tape running speed signal sent from the tape running speed detecting means so that the operation of the tape conveying means is stopped before movement of the endless tape is stopped. After conveying of endless tape is stopped, the endless tape continues moving for a while as the tape running speed of the endless tape decreases. Therefore endless tape accumulation near the loop bin outlet is prevented.
