<p>PURPOSE:To enable ophthalmological measurement in a short time by arranging a switch means for actuating a measuring device manually to operate the measuring device automatically when alignment is detected while the measuring device is allowed to operate manually when the alignment is almost achieved. CONSTITUTION:In an arithmetic processing circuit 10, an eye to be inspected aligns with respect to a device and when a photoelectric transducer 7 receives a specified quantity of light and detects it standing at the best point, a signal is outputted automatically to a driving circuit 17 to drive the device. On the other hand, when an manual switch 15 is activated with an alignment almost obtained, the arithmetic processing circuit 10 outputs a signal to the driving circuit 17 by the operation of the manual switch 15 even when the alignment is not at the best point. Thus, accurate measurement of an eye pressure is possible in a short time.</p> |
