Abstract: A head-mounted display has a rear arm, an accommodating part attached to the rear arm, a display arm that is held in the accommodating part, a display part which is pivotably attached to a tip end of the display arm, and headphones which are disposed on both end parts of the rear arm. 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. The 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: 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where the image display unit comes in front of a user's eye and a retracted position where the image display unit has been retracted from the front of the user's eye.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: Video display apparatus, remote controller for reproduction apparatus, and reproduction apparatus meeting user's usage conditions with high operability have structure including: remote controller for video display apparatus, the remote controller having connection section connected to video display section, operation members receiving operations by user to the video display section, and control section having at least two action modes for operating the video display section responding to operations to the operation members; attachment member attaching the remote controller for video display apparatus to user's clothes etc.

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.

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.

Abstract: The head-mounted display 1 has a rear arm 2, an accommodating part 3 that is attached to the rear arm 2, a display arm 4 that is held in the accommodating part 3 so that this display arm 4 can be accommodated, a display part 5 which is attached to the tip end of the display arm 4 so that this display part 5 can pivot, and headphones 6 which are disposed on both end parts of the rear arm 2, as main parts. A flat cable 12 which supplies a power source and signals to the image display device 7 is led into the accommodating part 3 via a wiring attachment part 13, and is fastened to the accommodating part 3 by the wiring attachment part 13. In the accommodating part 3, the intermediate part of the flat cable 12 is fastened by a wiring retainer 14. Then, this flat cable 12 enters the display arm 4 from the rear end part of the display arm 4, and is further conducted to the image display device 7 inside the display part 5 via a spherical-surface coupling 10.
