Description

TECHNICAL FIELD The present invention relates to an optometry apparatus capable of improving the degree of freedom in posture of a monitor unit.

It has a measuring head which is movable up, down, left, right, front and rear facing the subject and performs inspection while observing the image of the subject's eye through an optical system, and a joystick for operating the head, and the image of the subject's eye. There is known an optometric apparatus configured to increase the degree of freedom in arranging the operation/display unit with respect to the measurement head by connecting a cable to the operation/display unit that displays on the monitor section (see, for example, Patent Document 1. ).

Also known is an optometric apparatus in which a monitor section is rotatable with respect to a main body section of a controller device as an operation/display unit. The display screen of the monitor unit is a touch panel screen, and operation buttons and various image information are displayed on the touch panel screen.

The touch panel screen is directed to the side facing the examiner and the side facing the subject by rotating the monitor unit around the horizontal axis. The image information displayed on the touch panel screen is reversed vertically and horizontally, and the position of the button before rotation and the position of the button after rotation are visually the same. The position is controlled by a control circuit (see Patent Document 2, for example).

Also known is a monitor support device for an ultrasonic diagnostic apparatus that allows a user to easily move the monitor unit to suit his or her posture (see, for example, Patent Document 3). Furthermore, an ophthalmologic apparatus is also known in which a holding means is provided on the rear side of the measuring head to hold the monitor section so that it can be tilted from a substantially vertical state to a horizontal state (see Patent Document 4).
