Virtual image display apparatus

摘要

An optical unit housing section and a light guide device are supported by a frame. Durability of sections having an optical function in an entire apparatus is maintained. The frame is arranged on a side closer to the nose of an observer than the optical unit housing section and reduced in size. Consequently, a virtual image display apparatus can give an impression that the virtual image display apparatus is small in size in appearance as a whole. Further, it is possible to attain a reduction in the weight of the entire virtual image forming apparatus. Compared with a structure in which the entire apparatus is covered with a case-like member, the virtual image display apparatus can be formed in a shape closer to a form of eyeglasses. It is possible to attain design with apparent voluminousness suppressed.

主权项

1. A virtual image display apparatus comprising:
a video device; an optical unit housing section configured to house an optical unit including the video device; a light guide device arranged in front of eyes of an observer and configured to direct light emitted from the optical unit including the video device to the eyes of the observer and cause the observer to visually recognize an image; and a frame configured to support at least the optical unit housing section among components for image formation, wherein an outer edge of the frame is arranged on a side closer to a position where a nose of the observer should be arranged than an outer edge of the optical unit housing section, wherein a step is provided between the frame and the optical unit housing section, the frame supporting the optical unit housing section in a drooping state to form the step, the step being an expanding stair-like step, wherein the light guide device is adjacent, in a length-wise direction of the apparatus, to the optical unit housing section, and the light guide device is a fixed device, wherein the frame includes a metal frame portion and a disassemblable resin portion assembled to the metal frame portion to be dividable from the metal frame portion, the apparatus further including a boundary portion that separates the resin portion from the metal frame portion, and the frame includes a camera incorporated therein, a harness for the camera being incorporable in a state where the resin portion and metal frame portion are disassembled.
