Abstract

PURPOSE:To make the behaviors of a carriage at the times of forward and return movements, by connecting a running wire or belt to the carriage through a tension spring. CONSTITUTION:A fixing pin 8 is provided to a carriage 1 and a wire or belt 3 is passed through the transmission part receiving part 10 provided to the carriage 1 to be fixed to the fixing pin 8 through a tension member 9. Then, the carriage and the wire or belt of a transmission system can be fixed on the upper surface of the carriage and the vibration models at this time are almost equal at the time of the forward and return movements of the carriage. Since the vibration models are almost equal, the behaviors of the carriage at the times of forward and return movements are same. Therefore, the speed controls at the time of forward and return movements can be made same.

Therefore, in the present invention, the fixing pin 8 is attached to the carriage 1.
The wire or belt 3 is passed through the transmission part receiving part 10 provided on the carriage 1, and the wire or belt 3 is passed through the transmission part receiving part 10 provided on the carriage 1 and
It is fixed to the fixing pin 8 via two members 9. With this configuration, the carriage and the transmission wire or belt can be fixed on the upper surface of the carriage,
The vibration model at this time is as shown in FIGS. 3 and 4, and is almost the same during reciprocating movement. Since the vibration models are almost the same, the behavior of the carriage during reciprocating movement is the same. Therefore, the conventional control of slowing up and slowing down the carriage can be performed in the same way during forward and backward movement. With conventional technology, the vibration model differs between forward and backward, so each slow-up,
Considerations such as slowdown are different, and very difficult control must be performed.
