A coupling device for connecting a carriage to an actuator includes a reciprocating and rotating key pin assembly supported by the actuator, and a slotted latch plate mounted to the carriage. The key pin assembly is normally biased by spring means towards the actuator. To couple the carriage and actuator, the spring bias is removed and the key pin assembly is advanced towards the latch plate, rotated and firmly engaged therewith. A rotary shaft supported by and movable with the actuator reciprocates and rotates the key pin assembly. When the actuator and carriage are stationary at home position, the shaft is linked to an engaging acceptor means located at a predetermined position in a stationary housing. |
