Virtual image display apparatus with registration mechanism
First Claim
1. A virtual image display apparatus comprising:
- a virtual image formation unit that not only transmits environment light but also forms a virtual image from image light;
a positioning member that is attached in a predetermined position corresponding to a standard position of an optical system of the virtual image formation unit, the positioning member displaying a marker that allows a wearer in an apparatus worn state in which the wearer is wearing the virtual image formation unit to recognize the standard position and hence works as an index for positioning; and
a registration mechanism that moves the optical system of the virtual image formation unit and the positioning member attached to the optical system to adjust the position of the virtual image formation unit relative to a wearer'"'"'s eye,wherein the positioning member is detachably provided in the predetermined position, the positioning member being detachable without detaching the optical system.

Abstract
A wearer of a virtual image display apparatus can adjust the position of the virtual image display apparatus relative to the position of each of the wearer'"'"'s eyes by using a registration mechanism while checking a marker member that is a positioning member, whereby an optimum adjusted position is readily achieved. Further, registration according to person-to-person differences in the position of each of the eyes can be readily achieved, whereby it is not necessary to increase the light flux width of image light in advance or provide the image light with a margin so that the wearer can recognize an image even when the position of the eye deviates from a normal position to some extent, and the size of the apparatus will not increase.

11. A position adjustment method used with a virtual image display apparatus including a virtual image formation unit that not only transmits environment light but also forms a virtual image from image light, a positioning member that is attached in a predetermined position corresponding to a standard position of an optical system of the virtual image formation unit, the positioning member displaying a marker that allows a wearer in an apparatus worn state in which the wearer is wearing the virtual image formation unit to recognize the standard position and hence works as an index for positioning, a registration mechanism that moves the optical system of the virtual image formation unit and the positioning member attached to the optical system to adjust the position of the virtual image formation unit relative to a wearer'"'"'s eye, and
an information storage section that stores information on an adjusted position provided in the adjustment made by the registration mechanism, the method comprising: -
displaying the standard position by using the positioning member to allow the wearer to recognize a discrepancy between the standard position and the position of the wearer'"'"'s eye; and storing information on the adjusted position provided in the adjustment made by the registration mechanism based on the standard position displayed in the standard position display in the information storage section, wherein the positioning member is detachably provided in the predetermined position, the positioning member being detachable without detaching the optical system. - View Dependent Claims (14, 15)
