Head-mounted image display

Claim 2

A head-mounted image display comprising: a housing having a configuration of a dimension for covering a user's eye; means for removably mounting the housing on a head of the user; means provided at a predetermined position in the housing for emitting image light in a direction away from the user to form an image; a pair of right and left convex lenses, respectively, provided in a line of sight of the right and left eye of the user in the housing for enlarging the image produced by the image light emitting means; and optical means provided within the housing for guiding the image formed by the image light emitting means to the pair of right and left convex lenses for observation by the user.

Claim 3

A head-mounted image display according to claim 1, wherein the image light emitting means includes a liquid crystal display plate.

Claim 4

A head-mounted image display according to claim 1, wherein the image light emitting means is provided between the convex lenses in the housing.

Claim 5

A head-mounted image display according to claim 1, wherein the optical means comprises a prism disposed opposite to a light emitting surface of the image light emitting means and reflectors for guiding the image light emitted from the prism to the right and left convex lenses.

Claim 6

A head-mounted image display according to claim 1, wherein a convex lens is provided close to the light emitting surface of the image light emitting means.

Claim 7

A head-mounted image display according to claim 1, further including a small television tuner mounted on the user and operatively connected to the means for emitting image light.

Claim 8

A head-mounted image display according to claim 6, further including an image signal terminal on one side of the housing and a power terminal on the other side of the housing.

Claim 9

A head-mounted image display according to claim 6, wherein the means for emitting image light projects its image towards the user.

Claim 10

A head-mounted image display comprising: a housing for covering a user's eyes; a means for removably mounting the housing on a head of the user; means, fixed at a position that would be between both of the user's eyes when mounted with the housing and having a directed forward light emitting surface for emitting image light to form an image; a pair of right and left convex lenses provided at positions in front of the eyes in the housing for enlarging the image produced by the image light emitting means; a prism having an isosceles-triangular cross-section fixed within the housing and having a bottom surface facing the light emitting surface of the image light emitting means; and a pair of right and left reflector mirrors for guiding to the right and left convex lenses separately the image from the image light emitting means and exiting from left and right tilted surfaces of the prism so as to be perpendicular to those tilted surfaces.

Claim 11

A head-mounted image display comprising: a housing for covering a user's eyes; a means for removably mounting the housing on a head of the user; means, fixed at a position that would be between both of the user's eyes when mounted with the housing and having a directed forward light emitting surface for emitting image light to form an image; a pair of right and left convex lenses provided at positions in front of the eyes in the housing for enlarging the image produced by the image light emitting means; a prism having an isosceles-triangular cross-section fixed within the housing and having a bottom surface facing the light emitting surface of the image light emitting means; and a pair of right and left reflector mirrors for guiding to the right and left convex lenses separately the image from the image light emitting means and exiting from left and right tilted surfaces of the prism so as to be perpendicular to those tilted surfaces.

Claim 12

A head-mounted image display comprising: a housing for covering a user's eyes; means for removably mounting the housing on a head of the user; means in the housing for emitting image light to form an image; a pair of right and left convex lenses, respectively, providing in a line of sight of the right and left eye of the user in the housing for enlarging the image produced by the image light emitting means, the means for emitting image light is located within a plane containing the right and left convex lenses; and a plurality of sets of right and left reflectors provided between a light emitting surface of the image light emitting means and the right and left convex lenses for guiding the image from the image light emitting means separately to the right and left convex lenses.

Claim 13

A head-mounted image display comprising: a housing for covering a user's eyes; means for removably mounting the housing on a head of the user; means in the housing for emitting image light to form an image; a pair of right and left convex lenses, respectively, providing in a line of sight of the right and left eye of the user in the housing for enlarging the image produced by the image light emitting means, the means for emitting image light is located within a plane containing the right and left convex lenses; and a plurality of sets of right and left reflectors provided between a light emitting surface of the image light emitting means and the right and left convex lenses for guiding the image from the image light emitting means separately to the right and left convex lenses.

Claim 14

A head-mounted image display according to claim 10, wherein the image light emitting means is fixed within the housing such that the light emitting surface of the light emitting means faces the face of the user, and comprises a pair of first right and left reflector mirrors disposed in the form of a V opposite to the light emitting surface of the image light emitting means, and a pair of second right and left reflector mirrors for guiding the image in the image light emitting means reflected by the pair at first reflectors to the right and left convex lenses.
