PURPOSE: To decrease the injection amount of air and to perform an economical operation by constituting a slide surface plate so that a high pressure air is not injected from the fluid injection port of a slide surface plate located at the position where no sliding machine exists in the case of sliding the sliding machine onto a slide surface plate face with a low friction force.
CONSTITUTION: A solenoid valve 4 closing each of a lot of fluid injection ports 3 opened at specific pitch in the longitudinal and horizontal direction is provided on a slide surface plate 2 face. An antenna wire 5 is imbedded in the longitudinal and horizontal directions corresponding to the pitch of the injection port, a magnetic line of force M generated by the high frequency impressed on the sliding machine 1 which slides in a low friction state on the slide surface plate face is sensed by the antenna wire 5, only the solenoid valve 4 of the fluid injection port 3 of the lower face where the recognized slide machine 1 exists, is opened and the solenoid valve 4 of the fluid injection port of the part where no sliding machine 1 exists is closed. Thus the injection of unnecessary high pressure liquid is eliminated.
