Abstract
In a display device, a precoiled plastic tape bearing informational indicia runs over a back-up surface to present the front side of the tape for observation and for manual access to enable translating the tape. The tape also runs over stationary pins which allow the tape to coil when translated in one direction. Opposed ends of the tape are provided with apertures which are entered by the pins when one end portion of the tape is nearly uncoiled so that further translation and complete uncoiling of the tape is prevented. The tape end portion is automatically disengaged from the pins by the inherent coil forming stress in the tape when reverse translation is initiated.
