Abstract

PURPOSE:To allow an examinee in receiving compressed measuring gas at its necessary minimum, by providing a spraying block means for blocking the spraying of the measuring gas from a nozzle. CONSTITUTION:An eye H to be examined is irradiated with infrared rays by a projection system. Next, a piston 11 is raised by the revolution of a rotary solenoid 1 to compress the air in a compression chamber 14 to spray compressed air to the eye H to be examined from a nozzle 25. The cornea of the eye H to be examined is flattened under pressure by this spraying and, when an applanation detection signal is outputted from an applanation detection circuit 32, a control apparatus 37 stops output. The supply of a current to the rotary solenoid is stopped but the piston 11 further compresses the air in the compression chamber 14 by inertia. A current is supplied by the operation of a drive circuit 34 to operate a solenoid 18 and, since a valve 17 closes an air outlet 15 by this operation, the compressed air compressed by the inertia of the piston 11 is not supplied to the nozzle 25. Therefore, the spraying of the compressed air is blocked and compressed air is sprayed to an examinee at a necessary minimum.
