PURPOSE:To make the equipment compact and inexpensive by having a driving motor positioned at both ends of a rail running in linkage with a pulley and a pulley fixed on a type wheel through a transmission member. CONSTITUTION:Two driving motors 15 and 18 with the same output positioned at both ends of a rail 13 are made to run linkage with two pulleys 16 and 19 and a pulley fixed on a type daisy wheel 22 rotatably mounted on a carriage section 14 sliding on the rail 13 through one continuous transmission wire 25. By the operation of the two driving motors 15 and 18, the sliding of the carriage 14 and the rotation of the type daisy wheel 22 are done. This obviates the need for the type daisy wheel driving motor as in the past. |
