Description

  The present invention relates to a mirror system including a projector that projects an image and a half mirror that transmits the image.

  Conventionally, various video display apparatuses using a projector and a screen have been proposed (see, for example, Patent Document 1).

  In Patent Document 1, a wall separating a user's room and an adjacent room, the wall surface on the user's room side is constituted by a rear projection screen, and the projection light from the projector and the projector is reflected to reflect the rear. A video display system is described in which a reflecting mirror for incidence on a projection screen is arranged inside a wall.

  In the video display system described in Patent Document 1, since the projector and the reflecting mirror are arranged inside the wall that partitions the user's room and the adjacent room, the floor area of the user's room is substantially reduced. It is possible to display an image on a screen by a projector without reducing the size and without disturbing the user's room due to wiring or the like.

Further, by causing the projection light from the projector to enter the screen via the reflecting mirror, the optical path of the projection light from the projector is folded by the reflecting mirror, so that the wall thickness can be reduced.

Embodiments of the present invention will be described below with reference to the drawings. In the description of the drawings, the same parts are denoted by the same reference numerals.
(First embodiment)
With reference to FIG. 2, the external configuration of the mirror system according to the first embodiment of the present invention will be described. The mirror system 1 is used as a “partition” when forming a plurality of areas having different uses such as a bed and a washstand in a room. The mirror system 1 includes a first half mirror 23 provided on one side surface of the housing 33 and a deck 31 protruding from the lower end of the first half mirror 23. Although not shown in FIG. 2, a second half mirror is provided on the other side surface facing the one side surface of the housing 33.

  The configuration of the mirror system according to the embodiment of the present invention will be described with reference to FIGS. 1 (a) and 1 (b). FIG. 1A shows a state in which the mirror 22 reflects the image projected from the projector 21 toward the first space AS, and FIG. 1B shows the mirror 22 in the second space BS. The state where the image projected from the projector 21 is reflected is shown.

  The mirror system 1 includes a projector 21 that projects an image, a mirror 22 that reflects the image projected from the projector 21 by rotating itself, toward the first space AS or the second space BS, and the mirror 22. A first half mirror 23 that transmits the reflected image toward the first space AS, and a second half mirror 24 that transmits the image reflected by the mirror 22 toward the second space BS. .

  The projector 21 projects light rays constituting a predetermined image. The mirror 22 reflects the light beam projected from the projector 21 toward the first space AS or the second space BS. In the state of FIG. 1A, the mirror 22 reflects the light beam projected from the projector 21 toward the first space AS, and in the state of FIG. 1B, the mirror 22 projects the light beam projected from the projector 21. Is reflected toward the second space BS. The first space AS is a space on the side where the deck 31 is installed.

  The reflection direction is switched by rotating the mirror 22 itself. The way the mirror 22 rotates depends on whether the reflecting surface RS of the mirror 22 is only one side or both sides. When the reflecting surface RS of the mirror 22 is only one surface, it may be rotated counterclockwise from the state of FIG. 1A to the state of FIG. When the reflecting surface RS of the mirror 22 is double-sided, it may be rotated clockwise or counterclockwise from the state of FIG. 1A to the state of FIG.

  The first half mirror 23 faces the first space AS and transmits the light beam reflected by the mirror 22 in the state of FIG. 1A toward the first space AS. For example, by forming a diffusion layer for diffusing incident light rays on the surface of the first half mirror 23 on the mirror 22 side, the light rays are diffused when passing through the first half mirror 23. Therefore, the first half mirror 23 displays a predetermined image composed of light rays projected by the projector 21.

  The second half mirror 24 is provided to face the first half mirror 23 and faces the second space BS. Further, the second half mirror 24 transmits the light beam reflected by the mirror 22 in the state of FIG. 1B toward the second space BS.

That is, the first half mirror 23 and the second half mirror 24 are provided on both side surfaces of the housing 33, and the mirror 22 and the projector 21 are provided inside the housing 33.

  The projector 21 is disposed in the approximate center between the first half mirror 23 and the second half mirror 24 in the third space CS, and is approximately on the surface of the first half mirror 23 and the surface of the second half mirror 24. Project images in parallel directions.

  The projector 21 projects an image from the floor surface side to the ceiling side (upward), and the reflection surface of the mirror 22 that reflects the image faces obliquely downward. The image may be projected downward, leftward, or rightward, and the reflecting surface of the mirror 22 may be directed obliquely upward, rightward, or leftward.

  Further, the mirror 22 may be rotated by using a mirror rotating device, or may be operated by a lever operation by a user by protruding levers fixed to the mirror 22 from both side surfaces of the housing 33. I do not care. In FIG. 3, a case where a mirror rotating device is used will be described.

  With reference to FIG. 3, the configuration of the mirror system 1 relating to the control system of the projector 21 and the mirror 22 will be described. The mirror system 1 further includes a mirror rotating device 25 that rotates the mirror, a projector 21, a control unit 11 that controls the mirror rotating device 25, and a computer 10 that includes a memory 12 that stores video data projected by the projector 21. .

  The control unit 11 constitutes a part of a microprocessor having an arithmetic processing function such as a CPU of the computer 10 and operates according to a predetermined control program. The control part 11 receives the operation signal which a user transmits by wired or wireless from user interfaces, such as a remote control and a speech recognition apparatus. The projector control unit 13 transmits a control signal for controlling the operation of the projector 21 to the projector 21 based on the operation signal. The mirror control unit 14 transmits a control signal for controlling the operation of the mirror rotating device 25 to the mirror rotating device 25 based on the operation signal.

  The projector 21 receives a control signal from the control unit 11 and a video data signal stored in the memory 12 and projects a predetermined video, and the video is output 180 degrees according to the control signal from the control unit 11. And an image rotating unit 21b (image rotating means) for rotating. The image projected on the first half mirror 23 in the state of FIG. 1A is rotated 180 degrees by rotating the mirror 22 to the state of FIG. 1B. Therefore, the image rotation unit 21b rotates the image to be projected by 180 degrees in accordance with the rotation of the mirror 22. Thereby, the image transmitted through the first half mirror 23 and the image transmitted through the second half mirror 24 can be displayed in the same direction.

  The mirror rotating device 25 rotates the mirror 22 between the state of FIG. 1A and the state of FIG. 1B in accordance with a control signal from the control unit 11.

  With reference to FIG. 4, the installation example of the mirror system 1 shown in FIGS. 1-3 is demonstrated. In FIG. 4, the mirror system 1 is installed as a simple “partition” when a wash corner NS with a chair 44 and the like placed in a part of a room 41 which has been used as a bedroom MS by installing beds 42 a and 42 b. An example is shown. If the first space AS in FIG. 1 is a wash corner NS and the second space BS is a bedroom MS, the deck 31 can be used in the wash corner NS. Here, although the case of the bedroom MS and the wash corner NS is shown, the present invention is not limited thereto, and the bedroom and the study or study room may be partitioned.

  As described above, according to the first embodiment of the present invention, the following operational effects can be obtained.

  As the mirror 22 rotates, the image projected from the projector 21 is reflected toward the first space AS or the second space BS, and the first half mirror 23 reflects the image reflected by the mirror 22 to the first space AS. The second half mirror 24 transmits the image reflected by the mirror 22 toward the second space BS. Thereby, the mirror system 1 divides these areas even in one room and displays an image suitable for each application on the surface of each area (the bedroom MS and the wash corner NS) in the partition. be able to. In addition, by using the half mirrors 23 and 24 as the partition surface, the user can also use the mirror as a mirror. Therefore, even if the mirror system 1 is installed in the room, a feeling of pressure that makes the room narrower is used. Rarely feel. Therefore, the room can be shown wide when the image is not displayed.

  By providing the mirror 22 in the third space CS between the first half mirror 23 and the second half mirror 24, a desired image can be displayed in each of the facing rooms. Further, by providing the mirror 22 in the third space CS closed by the first half mirror 23 and the second half mirror 24, the reflectance of the mirror 22 is improved. Furthermore, by using the third space CS as a space for arranging the mirror 22, the space can be effectively used.

  By providing the projector 21 in the third space CS, the floor area for installing the projector 21 becomes unnecessary, and the floor is not messed up by the wiring connecting the projector 21. By providing the projector 21 and the mirror 22 in the third space CS, the image light projected from the projector 21 is folded back by the mirror 22 and passes through the first and second half mirrors 23 and 24. The distance between the half mirror 23 and the second half mirror 24 can be shortened.

The projector 21 includes the image rotation unit 21b that rotates the image by 180 degrees, so that the image transmitted through the first half mirror 23 and the image transmitted through the second half mirror 24 can be displayed in the same direction.
