摘要： An ophthalmologic alignment device for aligning a measuring system at a predetermined position for an eye to be examined. The user moves the measuring system with a joystick for aligning purposes while observing a frontal eye image with an observation unit. A second moving unit further moves the measuring system moved by the user. An index projection/detection system projects an index onto the eye and detects the reflected index. The controller causes drivers to drive the second moving unit on the basis of the result of the detection of the index projection/detection system. A mode switch switches the movement of the measuring system from a mode in which the observation unit is moved by the first moving unit to a mode in which the observation unit is moved by the second moving unit, whereby the alignment of the eye and the measuring system is achieved easily and with high accuracy, irrespective of the degree of the user's skillfulness in handling the alignment device.

摘要： In a non-contact type tonometer for blowing compressed gas against an examined eye through a nozzle, when a piston returns to an initial position by a biasing unit for biasing so as to return the piston to the initial position, a piston driving unit is actuated so as to attenuate the piston return speed by applying a force in the upwardly moving direction. Further, the piston is attached a piston rod so as to move in the axial direction of a cylinder, and is provided a gas passage which is closed when the gas is compressed and is opened when the piston returns to the initial position by the movement of the piston rod. Thus, the air compression chamber within the cylinder is caused to conductively connect to the atmospheric open chamber to thereby restrain the interior of the cylinder from becoming negative in pressure. In this way, it is possible to suppress the sucking-in of tears, dust, eyelashes and the like through the nozzle as effectively as possible with a simple structure.
