An image display apparatus includes a camera, a distance measurement sensor, an illuminance sensor, a brightness/darkness determinator, an image generator, an image storage, an image retriever, a visual image decider, and a display. The camera captures an image of a real object in front of a user to obtain a camera image. The image generator generates a distance image which corresponds to the camera image and represents a distance to each position of the real object based on data of the distance measurement sensor. The brightness/darkness determinator determines whether a place in which the user is present is a bright place or a dark place based on data of the illuminance sensor. The image storage stores the camera image and the distance image obtained in the bright place as a set.

Image display apparatus and image display system

A projector includes: a white light generator that uses a blue laser as a light source to generate blue light and yellow light based on the blue laser and generates white light including the generated blue light and yellow light; and an optical system that modulates light based on the white light generated by the white light generator with an image display element and projects the modulated light, wherein the white light generator includes: a dichroic mirror that is irradiated with the blue light from the blue laser as the light source; a first condenser lens that focuses blue light being reflected by or passing through the dichroic mirror; a diffusion plate that diffuses the blue light focused by the first condenser lens; a second condenser lens that focuses the blue light passing through or being reflected by the dichroic mirror; and a phosphor that emits yellow light.

Projector

A projector generates white light from a laser light source and uses the white light for image display. The white light generator has a rectangular light generating lens that generates excitation light of a rectangular shape from the blue light of a blue laser and a phosphor wheel, coated with a phosphor that is irradiated with the excitation light, to emit yellow light. In the phosphor wheel, a length in the vertical direction of a rectangular shape of an irradiation region is represented by v, and a length in the horizontal direction is represented by h, wherein h&#x3c;v; and a center of the rectangular shape is within any one of a region having an angle of 45&#xb0; or more and 135&#xb0; or less and a region having an angle of 225&#xb0; or more and 315&#xb0; or less in the phosphor coat region of the phosphor wheel.

An electric toothbrush includes a grip portion, a brush portion on which a replaceable toothbrush is mounted, and an illumination ring between the grip portion and the brush portion. The illumination ring is provided around the toothbrush as an annular structure so that a user can view the illumination ring no matter what angle he/she is holding the toothbrush.

The projector appropriately generates white light from a laser light source and uses the white light for image display. A white light generator that generates white light from blue light and yellow light includes a dichroic mirror that is irradiated with blue light from a blue laser, a first condenser lens that focuses the blue light that has passed through the dichroic mirror, a diffusion plate that diffuses the focused blue light, a second condenser lens that focuses the blue light obtained by allowing the diffused blue light to pass through the dichroic mirror, and a phosphor that is irradiated with the focused blue light to emit yellow light; the diffusion plate is an alumina ceramic plate; the dichroic mirror has a first region that transmits one of the blue light and the yellow light and reflects the other and a second region that reflects or transmits both.

An electric toothbrush includes a grip portion, a brush portion, and a joint arrangement for connecting the two portions. The joint arrangement has an upper cylinder portion and a lower cylinder portion, with an axis of the upper cylinder portion being inclined a predetermined angle with respect to an axis of the lower cylinder portion. The grip portion is connected to the lower cylinder portion and the brush portion is connected to the upper cylinder portion, so that the grip portion and the brush portion are inclined by the predetermined angle.

Electric toothbrush with rigidly connected grip portion and brush portion

An electric toothbrush includes a grip portion, a brush portion on which a replaceable toothbrush is mounted, and an illumination ring between the grip portion and the brush portion. The brush portion is inclined with respect to the grip portion. The illumination ring is provided around the toothbrush, so that a user can view the illumination ring no matter what angle he/she is holding the toothbrush.

A belt includes a belt main body extending in a long, narrow band. A frame-shaped body is attached to a first belt portion corresponding to a side on an end in a lengthwise direction of the belt main body. Multiple through-holes are formed in alignment in the lengthwise direction in a second belt portion corresponding to a side opposite to the first belt portion in the lengthwise direction of the belt main body. A locking member is included for attachment to a through-hole of the second belt portion so as to protrude from a front surface of the second belt portion. When the belt main body is mounted on the target object, the second belt portion is passed through the frame-shaped body, and the side of the frame-shaped body locks the locking member so as to prevent the second belt portion from coming out of the frame-shaped body.
