Patent ID: 7771050

Claim:
An ophthalmic apparatus which performs measurement of a plurality of eye characteristics of an examinee's eye, the apparatus comprising: a first measurement unit comprising a first measurement system for performing measurement of a first characteristic of the examinee's eye; a first alignment detecting unit arranged to detect an alignment state of a first measurement axis of the first measurement system with respect to the examinee's eye; a second measurement unit comprising a second measurement system for performing measurement of a second characteristic of the examinee's eye; a second alignment detecting unit arranged to detect an alignment state of a second measurement axis of the second measurement system with respect to the examinee's eye; a measurement unit comprising the first and second measurement units and the first and second alignment detecting units, the first and second measurement units being placed such that a height of the first measurement axis of the first measurement system and a height the second measurement axis of the second measurement system are different from each other; a movement mechanism unit arranged to move the measurement unit in a height direction, a right/left direction, and a back/forth direction; and measurement mode changeover means arranged to generate a changeover signal for carrying out a changeover between a first measurement mode for performing the measurement by the first measurement unit and a second measurement mode for performing the measurement by the second measurement unit; a memory arranged to store information on a position of the measurement unit that is detected at the time of the measurement in the first measurement mode, the information comprising at least information on a position in the height direction of the measurement unit; and a control unit arranged to control the movement mechanism unit, based on the stored information on the position of the measurement unit in the memory, such that the height of the second measurement axis at the time of the measurement in the second measurement mode becomes the same as the height of the first measurement axis at the time of the measurement in the first measurement mode when a changeover from the first measurement mode to the second measurement mode is carried out based on the changeover signal.
