PURPOSE:To detect, stop and display an objective pattern corresponding to a pattern mark by directly counting/detecting a pattern mark. CONSTITUTION:A driving pulley 15 is positioned/connected to a motor 13 fixed on a set plate 11. A driven pulley 18 is positioned/held at a position a set axial distance away from the driving pulley 15. A pattern belt is fitted between both pulleys 15, 18. A pattern 1 for complex plural frames is suitably disposed at specific intervals on a pattern display belt used as the pattern belt. A pattern mark 2b corresponding to a unit frame of all patterns and a reference mark 2a corresponding to a suitably selected pattern 1 are formed along one side of the pattern display belt. A detection/reading means 27 for detecting the respective marks 2a, 2b is disposed on the set plate 11. The pattern belt is shifted/stopped according to driving conditions in a rotary drive control mechanism 12 and detecting conditions in the detection/reading means 27. |
