PURPOSE:To prevent an ambulacral from twisting upon circulating of a pulse motor by composing of a connector having a connecting unit vertically to a platen for supplying a control signal, elevationally drive means for connecting and disconnecting the connector, and rotatably drive means for rotating a base by one revolution. CONSTITUTION:A male connector 8 of an ambulacral 2 is secured to a large gear 5 which is elevationally movably coupled to a main frame 14, and a female connector 9 is secured to the frame 14. The gear 5 is engaged in mesh with a rotary motor 7 via a pinion 6, can rise via an air pipe 3, and can fall by a spring 13. Further, an air connector base 17 is rotatably coupled to the frame 14 in such a manner that the rotary operation is synchronized by a guide bar 15 with the gear 5. This bar 15 is made free from the upward and downward movements of the gear 5. |
