Abstract: Inclination of an image display unit is prevented at the time of using a wearable display unit in which the image display unit can move between a projection position where the image display unit comes in front of a user's eye and a retracted position where the image display unit has been retracted from the front of the user's eye. A display support member 27 is prevented from rotating in relation to a display support member housing part 31 in a direction included in a plane perpendicular to the longitudinal direction of the display support member 27, even in a state that the display support member can move. To that end, grooves 28a, 28b extending in the longitudinal direction are formed in the display support member 27, while guide rollers 34a, 34a in contact with these grooves are provided within the display support member housing part 31.

Abstract: Provided is a technology for improving the wear comfort of a head-mounted display device. Cushions mounted on a head mounting band have surfaces that make contact with the user's head. The area of the contact surface of the cushion on the side whereupon a display unit is mounted is formed to be larger than the area of the contact surface of the other cushion.

Abstract: A cross key is mounted on a headphone. When a support arm and a connection section are pivoted 180 degrees from the (a)-state to change the position of wearing the headphone between left and right, a head-mounted display is set for use by the right eye, and this turns the cross key upside down. Correspondingly, a function allocated to the upper key is allocated to the lower key and a function allocated to the lower key is allocated to the upper key to obtain the (b)-state. In the (b)-state, the functions are changed such that the function allocated to the upper key is allocated to the upper key and the function allocated to the lower key is allocated to the lower key. A cross key does not require any change in key functions and left as is.

Abstract: The head-mounted display has a rear arm, an accommodating part that is attached to the rear arm, a display arm that is held in the accommodating part so that this display arm can be accommodated, a display part which is attached to the tip end of the display arm so that this display part can pivot, and headphones which are disposed on both end parts of the rear arm, as main parts. A flat cable which supplies a power source and signals to the image display device is led into the accommodating part via a wiring attachment part, and is fastened to the accommodating part by the wiring attachment part. In the accommodating part, the intermediate part of the flat cable is fastened by a wiring retainer. Then, this flat cable enters the display arm from the rear end part of the display arm, and is further conducted to the image display device inside the display part via a spherical-surface coupling.

Abstract: The head mounted display of the present invention has a display part for displaying images to the wearer, a supporting part which supports the display part, which is fed out into a position in front of as eye from a position that is not located in front of the face, and which is moved from this position in front of as eye into this position that is not located in front of the face, and a mounting part which holds this supporting part, and which is mounted on the wearer in a position that is not located in front of the face, and is constructed so that the supporting part can move past the side of the head along the contour of the head. As a result, a display device is produced which is relatively free of unsightliness with respect to the wearer.

Abstract: Switches and the like 6 that are used to control video images displayed on the display part 5 are installed on the headphone 1 for the left ear to which no display arm holding part 3 or display arm 4 is attached. The user operates these switches and the like 6 with the left hand. Since these switches and the like 6 are attached to the headphone 1 for the left ear, which is on the side opposite from the headphone 1 for the right ear to which the display arm holding part 3 and display arm 4 are attached, there is no touching of the display arm holding part 3 or display arm 4 by hand during the operation, thus reducing the possibility of the position of the display part 5 being altered.

Abstract: A head mount display having a display part rotatable relative to a head mount band, which is improved in portability and in which the display part can be protected. A restraint part (170) is provided on the outside of the head mount band (110). The restraint part (170) is provided with a holding part (173) for holding an arm part (150) connected to the display part (160).

Abstract: A head mount display having a display part rotatable relative to a head mount part, in which, when the display part is rotated and retreated from in front of the eyes to the top of the head of the wearer when not is use, the display part is less possible to come into contact with the forehead or hair of the wearer during its rotation. The head mount display has an arm part at the forward end of which the display part is mounted and mounting parts for fitting the other end of the arm part to the head mount part. The other end of the arm is mounted by the mounting parts to the head mounting part so as to be rotatable in the direction where the forward end of the arm part is separated from the mounting parts and so as to be displaceable in the direction.

Abstract: In a visual training device and a visual training method, different targets are displayed for right and left eyes, respectively, and refractivities of the right and left eyes are measured. Based on the measured refractivities of the eyes, positions of the targets displayed for the right and left eyes are moved in the directions of the respective optical axes. At the same time, the targets are moved so that the visual axes of the right and left eyes incline outward toward the end. The directions of the visual axes of the right and left eyes incline outward toward the end, so that it is possible to relax the strain of musculus ciliaris and relieve visual fatigue through short, effective training.

In this microscope, at least two of the units are imparted with conducting properties with conducting abilities different from each other.

Abstract: The subjective eye refractive power measuring apparatus according to the present invention objectively measures the refractive power of an optical system to be tested. The subjective eye refractive power measuring apparatus comprises a measuring element that output a detection signal corresponding to the refractive power of the optical system to be tested, an arithmetic device that calculates a measured value related to the refractive power based upon an output signal from the measuring element, a determination device that determines whether or not specific conditions related to termination of a measuring operation are satisfied based upon, at least, either a measured value obtained by the arithmetic device or the length of measurement time required for measurement and a termination device that implements specific control for terminating a measuring operation when the judgement device has determined that specific conditions are satisfied.

Abstract: An ophthalmologic curvature measuring device measures the shape of a central portion and the shape of a peripheral portion of a curved surface such as a cornea of the eye or contact lenses. The measuring device has a small size and is capable of being hand held during measurement. A plurality of light beams are first projected onto the cornea and corneal periphery of the eye. A first projection unit then projects a first mark onto a first region of the subject eye while a second projection unit projects a pair of second marks onto a second region of the subject eye. An objective lens transmits reflected images of the first and the second marks to a measurement unit which measures the second marks at first and second timings.

Abstract: An ophthalmologic apparatus comprises an eye examining apparatus of the hand-held type, an auxiliary apparatus on which the eye examining apparatus is removably mounted, a discrimination circuit for discriminating whether the eye examining apparatus and the auxiliary apparatus are connected together or separated from each other, and a controller for operatively associating the eye examining apparatus and the auxiliary apparatus with each other when the discrimination circuit discriminates that the eye examining apparatus is connected.
