  According to these inventions, when the display member is moved by the display member moving means or the image member is moved by the image member moving means, the transmission portion of the display member corresponds to each image out of the light transmitted through the image member. Each pixel portion is passed through the side opposite to the image member side, that is, the observer side where the observer observes the image display device. Therefore, an image composed of pixels corresponding to the pixel portion, for example, an advertisement image, is displayed on the viewer side by light transmitted through only the pixel portion corresponding to each image. Thereby, since each image can be displayed without using an element for each pixel as in the prior art, the manufacturing cost can be reduced. Moreover, since the advertisement image can be displayed by the light emitting means without using an element for each pixel as in the prior art, the power consumption can be reduced and the maintenance cost can be reduced.

  In the present invention, the image display device further includes a condensing unit that condenses light passing through the transmission unit.

  According to the present invention, the light that has passed through the pixel portion corresponding to each image facing the transmissive portion of the pixel portion of the image member and passed through the transmissive portion to the viewer side of the display member is collected by the light collecting means. For example, it can be set as the state which condensed in the area | region which an observer observes. Therefore, since the diffusion of the light that has passed to the viewer side is suppressed, the image can be displayed brightly, and the visibility of the viewer is improved.

  According to the present invention, in the image display device, the area of each transmissive portion is smaller than the area of one pixel portion of the image member.

  According to this invention, since the area of each transmission part is narrower than the area of one pixel part of the image member, each image of the light transmitted through the pixel part corresponding to each image among the pixel parts of the image member. Only a range that is slightly narrower than the range of the pixel portion corresponding to is passed through the transmissive portion to the viewer side of the display member. Therefore, it is possible to suppress the light passing through the transmissive part to the viewer side of the display member from including light transmitted through other than the pixel part corresponding to each image. Thereby, the noise of the displayed image can be suppressed.

  In the present invention, the image display device is characterized in that the plurality of images are still images of each frame of a moving image.

  According to the present invention, the transmission unit allows light that passes through only the pixel unit corresponding to the pixels constituting the still image of each frame of the moving image to pass through the viewer side in the display order of each frame of the moving image. Therefore, even if a moving image, for example, a moving image advertisement is displayed, the manufacturing cost and the maintenance cost can be reduced.

  In the present invention, the image display device further includes a diffusing unit that diffuses light emitted from the light emitting unit, and the light transmitted through the image member is diffused by the diffusing unit.

  According to the present invention, for example, by diffusing means between the light emitting means and the image member, or by using the image member itself as the diffusing means, the light transmitted through the image member is diffused. Therefore, the intensity of the light passing through the transmission part of the display member can be made uniform regardless of the positional relationship of each transmission part with respect to the light emitting means. As a result, on the viewer side, the light transmitted only through the pixel portion corresponding to each image becomes uniform, and an image composed of pixels corresponding to this pixel portion, for example, a part of the advertisement image is suppressed from being darkened. can do.

  The image display device according to the present invention has an effect that the manufacturing cost and the maintenance cost can be reduced.

  Next, as shown in FIG. 4, a plurality of (M × N) pixel unit groups in which each K × M × N pixel units of the pixel unit group are divided into pixel units in each pixel unit group. They are arranged in vertical M rows and horizontal N columns according to the division position in the advertisement image. In this embodiment, nine pixel unit groups (M1N1 group to M3N3 group) in which the pixel units A11 to I33 of the pixel unit group 31 are divided into nine pixel unit groups (M1N1 group to M3N3 group). ) Are arranged according to the division positions in the advertisement images A to I of the pixel portions A 11 to I 33. Here, the nine pixel unit groups are arranged in three rows and three columns. Thereby, the pixel unit group 31 has the upper column (M = 1) in the order of the M1N1 group, the M1N2 group, and the M1N3 group, the middle column (M = 2) in the order of the M2N1 group, the M2N1 group, and the M2N3 group, and the lower side. Column (M = 3) is in the order of M3N1 group, M3N1 group, and M3N3 group.

  Next, as shown in FIG. 5, the image portions arranged on the image member are different from each other in the image portion corresponding to the same image in each of the X image portion groups adjacent to each other in the moving direction of the display member, that is, the rotation direction. It arranges within each pixel part group so that it may become a row. In this embodiment, all of the image portions A11 to I33 of the pixel portion group 31 arranged on the image member 3 are in three (X = 3) image portion groups adjacent in the rotation direction of the pinhole panel 4. The image portions corresponding to the same image are arranged in different rows. For example, in the pixel portions A11, A12, A13 corresponding to the advertisement image A that is the same image in the M = 1 group (M1N1 group, M1N1 group, M1N3 group) of the pixel portion group 31, or the advertisement image D that is the same image. The corresponding pixel portions D11, D12, and D13, the pixel portions G11, G12, and G13 corresponding to the advertisement image G that is the same image, and the like are arranged in different rows. In the group of M = 2 and M = 3, the image portions facing the same image are similarly arranged in different rows.

  Then, as shown in the figure, the image portions arranged on the image member are arranged in the pixel portion groups in which the pixel portions adjacent in the moving direction of the display member, that is, the rotation direction are in the display order of K advertisement images. Arrange. In this embodiment, all of the image portions A11 to I33 of the pixel portion group 31 arranged on the image member 3 are adjacent to each other in the rotation direction of the pinhole panel 4 with 9 (K = 9) advertisement images A. Are arranged within each pixel unit group (M1N1 group to M3N3 group) so as to be in the display order of .about.I. For example, as shown in the figure, image portions A11 to I33 adjacent to each other in the rotation direction of the pinhole panel 4 are A11, B11, C11, D12, E12, F12, G13, As shown in the order of H13, I13 and the order of A23, B23, C23, D21, E21, F21, G22, H22, I22, the image portions corresponding to the pixels constituting the advertising images A to I in the rotation direction are A. Arranged to repeat the sequence of ~ I.

  The pinhole panel 4 is a display member, and is formed in a ring shape as shown in FIG. 1, and is housed in a casing 5 so as to surround the light source 2 and the image member 3 as the light emitting means. That is, the pinhole panel 4 is disposed to face the light source 2 with the image member 3 interposed therebetween. The pinhole panel 4 is disposed on the casing 5 such that one surface thereof, that is, the surface on the viewer side where the viewer 100, which is the side opposite to the image member side, observes the image display device 1 is exposed from the casing 5. It is fixed. The pinhole panel 4 is configured by printing a transparent film in black except for a transmission portion described later, and the portion printed in black does not transmit light. Therefore, the light from the light source 2 that has passed through the image member 3 other than the portions facing the transmitting portions 41a to 41i, which will be described later, does not reach the outside of the casing 5, that is, the viewer side by the pinhole panel 4. The pinhole panel 4 may be formed of, for example, a black plastic plate or a metal plate as long as it does not transmit light. The pinhole panel 4 may be provided so as to face the casing 5 with the image member 3 interposed therebetween. Thereby, an image can be displayed from both side surfaces of the image display device 1.

  As shown in FIG. 6, the pinhole panel 4 includes a transmissive portion that transmits light diffusing through the image member 3 to the opposite side of the image member side, that is, the viewer side. M × N are formed so as to correspond to each of the above, and at least one set of the transmission portion group consisting of M × N is provided. In this embodiment, three sets of transmission parts including nine transmission parts 41a to 41i, 42a to 42i, and 43a to 43i so as to correspond to the respective pixel part groups (M1N1 group to M3N3 group) of the pixel part group 31. The groups 41, 42, and 43 are formed so as to be adjacent to each other in the moving direction of the pinhole panel 4 that is a display member. The transmissive portions 41a to 41i, 42a to 42i, and 43a to 43i of the transmissive portion groups 41 to 43 are respectively the advertisement images A to I33 among the pixel portions A11 to I33 of the pixel portion groups (M1N1 group to M3N3 group). The pixel portion corresponding to I is formed to face the pixel portions A11 to A33 corresponding to the advertisement image A in this embodiment. Thereby, the transmission parts 41a to 43i are only the pixel parts corresponding to the advertisement images A to I among the pixel parts A11 to I33 of the image member 3, for example, only the pixel parts A11 to A33 corresponding to the advertisement image A, or the advertisement. Light that passes through only the pixel portions C11 to C33 corresponding to the image C and only the pixel portions G11 to G33 corresponding to the advertisement image G is allowed to pass to the viewer side. Each of the transmission parts 41 a to 43 i is formed so that the area thereof is the same as the area of one pixel part formed on the image member 3.

  The pinhole panel 4 is supported by two rollers 51 and 52 rotatably supported by the casing 5 so as to be rotatable in the rotation direction of the rollers 51 and 52. A motor 53 which is a display member moving unit is connected to the roller 51. The motor 53 is supplied from a power supply unit (not shown) when displaying an image, here an advertisement image, by the image display device 1. The roller 51 is rotated in the arrow S1 direction by electric power. The pinhole panel 4 rotates in the rotation direction which is the arrow S2 direction with respect to the image display member 3 when the roller 51 rotates in the arrow S1 direction. In addition, when the rotation speed of the motor 53 is high, a reduction gear may be interposed between the rollers 51.

  Next, the operation of the image display device 1 will be described. As shown in FIG. 7, first, the pinhole panel 4 is placed on the image member 3 so that the pixel portions A11 to A33 corresponding to the advertisement image A are opposed to the transmission portions 41a to 41i of the transmission portion group 41, respectively. Arrange. Therefore, in the display advertising device 1 in this state, light that passes through the image parts A11 to A33 corresponding to the advertisement image A passes through the transmission parts 41a to 41i and reaches the viewer side. Thereby, the advertisement image A is displayed on the viewer side, and the viewer 100 visually recognizes the advertisement image A from the image display device 1.

  Next, by driving the motor 53, the pinhole panel 4 rotates in the rotation direction with respect to the image member 3 when the pinhole panel 4 is rotated in the rotation direction (the direction of arrow S <b> 2 in FIG. 1). Therefore, each transmission part 41a-43i moves to a rotation direction, and the image part of the image member 3 which opposes each transmission part of the part exposed outside from the casing 5 among each transmission part 41a-43i is shown in FIG. As shown, the image portions A11 to A33 corresponding to the advertisement image A are changed to image portions B11 to B33 corresponding to the advertisement image B, and the light transmitted through the image portions B11 to B33 passes through the transmission portions 41a to 41i and is observed. It will reach the person side. Thereby, the advertisement image B is displayed on the observer side, and the observer 100 visually recognizes the advertisement image B from the image display device 1.

  Further, when the pinhole panel 4 rotates in the rotation direction with respect to the image member 3 by driving the motor 53, the image portion of the image member 3 facing the transmission portions 41a to 41i is as shown in FIG. From the image parts B11 to B33 corresponding to the advertisement image B to the image parts C11 to C33 corresponding to the advertisement image C, the image parts D11 to D33 corresponding to the advertisement image D, the image parts E11 to E33 corresponding to the advertisement image E, the advertisement image The image portions F11 to F33 corresponding to F, the image portions G11 to G33 corresponding to the advertisement image G, the image portions H11 to H33 corresponding to the advertisement image H, and the image portions I11 to I33 corresponding to the advertisement image I are changed in this order. , Light that passes through the image parts C11 to C33, light that passes through the image parts D11 to D33, light that passes through the image parts E11 to E33, light that passes through the image parts F11 to F33, and image parts G11 to G11 Light transmitted through 33, so that the light transmitted through the image portion H11～H33, through the transmissive portion 41a~41i in the order of light transmitted through the image portion I11~I33 reach the observer side. Thereby, the advertisement images A to I are displayed in order on the viewer side, and the viewer 100 visually recognizes the advertisement images A to I from the image display device 1 in order. If the image member 3 continues to rotate in the rotation direction with respect to the pinhole panel 4 by driving the motor 53, the advertisement images A to I are repeatedly displayed in order on the viewer side.

  As described above, when the pinhole panel 4 serving as the display member is rotated by the motor 53 serving as the display member moving unit, each of the transmission portions 41a to 41a of the transmission portion groups 41 to 43 of the pinhole panel 4 serving as the display member. 43i passes through the light transmitted through and diffused through the image member 3 to the opposite side of the image member side, that is, the observer side where the observer observes the image display device 1 for each pixel portion corresponding to each advertisement image A to I. Let Therefore, the advertisement images A to I including the pixels corresponding to the pixel portions are sequentially displayed on the viewer side by the light that passes through only the pixel portions corresponding to the advertisement images A to I. Therefore, the image display device 1 can repeatedly display one moving image advertisement having nine advertisement images A to I as respective frames.

  As a result, an image, here, a moving image advertisement can be displayed without using an element for each pixel as in the prior art, and thus the manufacturing cost can be reduced. Moreover, since the advertisement image can be displayed by the light emitting means without using an element for each pixel as in the prior art, the power consumption can be reduced and the maintenance cost can be reduced. Further, when changing each image displayed by the image display device 1, it is only necessary to replace the image member 3, thereby suppressing an increase in maintenance cost and changing each image displayed by the image display device 1. It can be done easily.

  An image display device using a lenticular lens is also conceivable as an image display device that reduces manufacturing costs and maintenance costs. This lenticular lens displays different images depending on the viewing angle. Therefore, the image display device using the lenticular lens can display a moving image by displaying a plurality of images or continuous still images. However, in the image display device using this lenticular lens, the number of images that can be displayed depends only on the number of divisions of each image in the moving direction of the observer. This is because each image cannot be divided in a direction orthogonal to the moving direction of the observer. That is, the image display device using the lenticular lens has a problem that it is difficult to display a moving image on the image display device because the number of images that can be displayed is small. However, in the present invention, since each image can be divided vertically and horizontally, the number of images that can be displayed can be increased as compared with an image display device using a lenticular lens. Thereby, since many still images of each frame of a moving picture can be displayed, a moving picture can be displayed smoothly.

  In addition, the image display device using this lenticular lens has a problem that each image and moving image, that is, all the images that can be displayed cannot be viewed unless the observer moves. However, according to the present invention, each of the transmissive portions 41a to 43i of each of the transmissive portion groups 41 to 43 allows the viewer to transmit light that passes through only the pixel portion corresponding to each of the advertisement images A to I in the display order of each of the advertisement images A to I. Since the advertisement images A to I are displayed on the side, all advertisement images that can be displayed by the viewer 100 can be viewed without the viewer 100 moving.

  In this embodiment, since the image member 3 itself is a diffusing unit, the light transmitted through the image member 3 can be diffused. Therefore, the intensity of the light passing through each of the transmission parts 41a to 43i of the pinhole panel 4 that is a display member can be made uniform regardless of the positional relationship of each of the transmission parts 41a to 43i with respect to the light source 2 that is the light emitting means. it can. As a result, the light transmitted only through the pixel portions corresponding to the respective advertisement images A to I is uniform, and the advertisement images A to I configured from the pixels corresponding to the pixel portions are prevented from being partially darkened. Can do.

  Here, the advertisement images A to I in the above embodiment may be still image advertisements. In this case, the image display device 1 repeatedly displays a plurality of still image advertisements in order. Further, by intermittently rotating the motor 53, the rotation of the pinhole panel 4 can be stopped, and it corresponds to the pixel portion facing each of the transmission portions 41a to 43i while the rotation of the pinhole panel 4 is stopped. The advertisement image to be displayed can be displayed for a long time.

  Further, in the pinhole panel 4 in the above embodiment, three sets of transmission portion groups 41 to 43 are formed, but each of the transmission portions 41a to 41i of the one transmission portion group 41 in the rotation direction of the pinhole panel 4. May be formed.

  Moreover, in the said Example, as a selection method of 1 pixel part corresponding to each advertisement image AI included in each pixel part group (M1N1 group-M3N3 group), in each pixel part group (M1N1 group-M3N3 group) Although it selected so that it might become the same as the division | segmentation position in each advertisement image of this image part, this invention is not limited to this. For example, even if the division position in each advertisement image of the image part in each pixel part group (M1N1 group to M3N3 group) is the same and the division position in each advertisement image for each row is selected to be continuous, You may select so that the division position in each advertisement image of the image part in each pixel part group (M1N1 group-M3N3 group) may be continuous, and the division position in each advertisement image of each line may become continuous.

  9 and 10 are diagrams showing another configuration example of the image member. As shown in FIG. 9, each pixel unit of each pixel unit group (M1N1 group to M3N3 group) has the same division position in each advertisement image A, B, and C in each row (X = 3). A pixel portion where division positions are continuous, a division position in each advertisement image D, E, F is the same, a pixel portion where division positions are continuous with other rows, and a division position in each advertisement image G, H, I is the same. Selection is made so that the pixel portion is continuous in row and division position. For example, in the M1N1 group, the pixel portions A11, B11, C11 in which the division positions in the respective advertisement images A, B, and C are the same and the division positions are continuous in the other rows and the respective advertisement images G, H, and I in the respective rows.
