Abstract
PURPOSE: To perform the switching of air with lesser noise by using an air switcher having a system in which vacuum and pressure switch timing operation is performed by the same drive source for a magnetic tape device.
CONSTITUTION: When switching is needed, a supply port A is closed and a supply port B is opened to send air, whereupon a piston 12 is moved to the left, a pressure switcher 13 is also moved to the left, and thereby a sending port D is closed and the small supply outlet of a sending port E is opened. On the other hand, a vacuum switcher is also moved to the left and the gas of a chamber 16 is exhausted through its opening 14' and treated in the same way as the case of the exhaust gas of a chamber 15. Under the condition, a vacuum function and a pressure function are both effected. The switching between the vacuum function and the pressure function is performed by adjusting the pressure compressed air supplied from the supply ports A and B or by adjusting the moving distance of the piston.
