Abstract: A light direction adjustment mechanism and an imaging device that enables size reduction are provided. The adjustment mechanism includes a first optical element (201), a second optical element (202) having a same optical axis as that of the first optical element (201), and a rotation mechanism (63). The rotation mechanism (63) allows the first optical element (201) to rotate while the rotation mechanism (63) changes a rotation angle of the first optical element (201) relative to the second optical element (202) when the first optical element (201) is rotated about the optical axis in a first direction. The rotation mechanism (63) allows the first optical element (201) to rotate while the rotation mechanism (63) does not change the rotation angle of the first optical element (201) relative to the second optical element (202) when the first optical element (201) is rotated about the optical axis in a second direction.

Abstract: A fixing structure 14 comprises a plate-like member 15, a housing 16, and an adhesion body 17. The plate-like member 15 has an engaging portion 18. The housing 16 has a protrusion 19. At least part of an outer peripheral wall surface of the protrusion 19 faces an inner peripheral wall surface defining the engaging portion 18. The protrusion 19 has a recess formed from a tip thereof along a protruding direction. The adhesion body 17 is interposed between the engaging portion 18 and the protrusion 19 and fixes the plate-like member 15 to the housing 16. The protrusion 19 has communicating portions that communicate between the recess and an outer periphery of the protrusion 19 and are distributed around an axis extending in the protruding direction. The adhesion body 17 is located from the recess to a space between the engaging portion 18 and the protrusion 19 through the communicating portions.

Abstract: An image display device includes optical elements that are a left eye member and a right eye member. The image display device has an image display element that displays an image to an observer through the left eye member and the right eye member. The left eye member and the right eye member each have at least one part shape formed so as to avoid the contact with the nose of the observer. The surface of the at least one part shape is substantially parallel to the direction of a principal ray from the image display element.

Abstract: A head-mounted device to be worn on a user's head includes a first pressing member to press, for example, an occipital region, a second pressing member to press, for example, a parietal region, and first and second linear members connected to the first and second pressing members respectively. The first and second linear members are guided so that a change in lengths of the first and second linear members causes the first and second pressing members to move in the first and second directions respectively. An adjustment unit to adjust the lengths of the first and second linear members includes first and second wind-up units connected to a rotational operation member and to wind up the first and second linear members respectively.

Abstract: The invention provides a head mounted image-sensing display device including a pair of image-sensing units (18R, 18L) that stereoscopically capture a physical space and output a pair of stereoscopic images, and display units (13R, 13L) for displaying images for the right eye and images for the left eye. Image sensing parameters that are previously measured for the image-sensing units are stored in image sensing parameter storage units (26R, 26L). As a result, a difference in parallax between captured images of a physical space and images of a virtual object is reduced.
