Abstract
PURPOSE:To reduce the cost, by providing a mobile body which is supported possibly for reciprocation for a given straight line section and a chain 13 which moves in a given timing and a part of which is suspended in parallel with the said section. CONSTITUTION:A mobile body 15 as an original stand is fixedly provide with a latch piece 16 such as an actuator, and a latch groove 16a is formed on the piece 16. A chain 13 is fitted with a roller 27 latched to the latch piece 16. Since the forward moving of the mobile body 16 is made through chain drive by latching the roller 27 provided with the chain 13 with the piece 16 provided with the mobile body 15 and the start of movement of the body 15 is made detaching the piece 16 from the roller 27, low cost manufacture can be made in comparison with conventional methods using gear, chain and wire.
