Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-transmissive image unit using a relatively large-sized image film of Japanese Industrial Standard A4 to A2 or higher.

[0002]

2. Description of the Related Art Conventionally, an optical display device which can be viewed mainly by illumination from the rear using a composite image formed by superimposing two images containing the same image information is disclosed in Japanese Patent Publication No. 59-59. It is disclosed in Japanese Patent No. 502078 or Japanese Patent Laid-Open No. 6-250595.

An image plate for transmitted light and reflected light in which a semi-transparent plate is placed in the center and the same images are arranged on both sides of the plate and the images are completely aligned and fixed is disclosed in Japanese Patent Laid-Open No. 63-201.
There is 685 publication.

[0004]

Among the conventional examples, Japanese Patent Publication No. 502078/1984 is the same as the present invention in that a composite image obtained by superposing two identical images is used.
However, in this publicly known example, the effect of the optical display by adjusting the density of the image and the structure of the film whose thickness is studied so that the two images come into contact with or separate from each other has been earnestly studied. Therefore, the size of the film is A
Although it is not disclosed to handle a relatively large version of the image in rows 4 and above, and a structure in which transparent plates are provided in front of and behind the image plate is shown, a laminated body of the same size as the image plate is shown. It does not disclose the use of a transparent plate that remains and covers the image plate.

The second Japanese Laid-Open Patent Publication No. 6-250595 discloses a structure in which the same image is formed on a plurality of transparent films and superposed to form an image sheet, and a transparent plate is adhered to the surface. In this known example, the means for superimposing two transparent films to form an image sheet is the same, but a means for laminating a transparent plate with a size so as to cover the image sheet and providing an edge portion is a technical problem. Is different.

Further, in Japanese Patent Laid-Open No. 63-201685, a semitransparent plate is sandwiched in the middle so that the same images are fixed so that they are completely aligned with each other. Causes a decrease in luminous intensity or brightness,
It is not possible to obtain the three-dimensional feeling as when transmitting two images formed on a transparent plate. Regarding the light from the front, an image transmitted through one image plate and reflected by the semitransparent plate is viewed, and the present invention is different in the way of grasping the problem.

It is similar to the present invention in that it provides means for strengthening the weather resistance by applying or coating an ultraviolet absorbing film on the surface plate, but a large plate transparent plate for covering the image plate is used. The configuration is different from that of the present invention in which the edging portion is formed in the peripheral portion by using the edging portion.

An object of the present invention is to form two image sheets of a relatively large size, position them correctly, and superimpose them correctly to form an image sheet. A transparent plate larger than this image sheet is laminated to complete the image sheet. It provides an image unit that covers and has an edge portion on the periphery, and it is easy to load it into the frame for display using the edge portion, and multiple image units can be prepared and replaced according to the season or event In addition, the present invention provides an image unit that is large in size, can retain rigidity, is highly weather resistant, and can be used for a long period of time.

[0009]

[Means for Solving the Problems] The first invention is to provide two transparent films on which a same image is formed on a relatively large plate of Japanese Industrial Standard A row No. 4 or more, and two transparent films on the same. The image is correctly positioned and accurately overlapped to form an image sheet, and a transparent plate that is slightly larger and stronger than this image sheet is pressure-bonded integrally on the front and back surfaces, and a rim with edges at both edges or opposite edges The plate and the front and back laminate plates were a light-transmissive image unit which is a material having an ultraviolet ray blocking property.

In the second aspect of the invention, a light transmissive image unit using a light diffusing plate is used instead of the transparent plate on the back side to be laminated.

(Operation) In the first invention, two transparent films on which the same image is formed are provided on a relatively large plate of Japanese Industrial Standard A row No. 4 or larger, and the two transparent films are formed on the two transparent films. Images were correctly positioned and accurately superimposed to form an image sheet.

Since two relatively large transparent films of A4 size or more are superposed on each other to form an image sheet, a flexible transparent film tends to bend, but in the present invention, in order to prevent this, the image state in which the superposed images are accurately superposed. Was laminated with a laminate plate so as to cover the whole, and integrated by pressure bonding to complete an image unit.

When the thickness of the image sheet is set to, for example, about 0.1 mm and the image is irradiated from the rear side by the optical system, the two images are overlapped with each other and the contrast is good, the accuracy and the depth of the hue are increased, and the image can be clearly expressed. It became so.

By laminating transparent plates, which are slightly larger and stronger than the image sheet, on the front and back sides and press-bonding them together, there is no displacement of the image position, the surface is tough, and the rigidity as a whole can be obtained to form an image. Since the edging portion is protected and only the transparent plate is formed on the peripheral edge portion or the opposite end edge portions, the edging portion can be utilized to facilitate mounting on the frame body as the display device. For example, the edging portion of the image unit may be inserted into the slit portion provided in the frame body as the display device.

Further, by forming the transparent plates on the front and back sides of a material having an ultraviolet ray blocking property, it is possible to provide a light transmissive image unit having light resistance and capable of withstanding long-term use.

According to the second aspect of the invention, instead of the transparent plate on the back side to be laminated, a laminate plate using a light diffusion plate is used, and the laminate plates on the front and back sides are image units made of a material having an ultraviolet blocking property.

By using the light diffusing plate, light from the light source on the back side can be diffused as an image unit to display an image clearly, and the back side is clearer than the case where a transparent plate is used for both the front and back sides. There is the convenience that it can be used as a display simply by arranging it in front of the light source.

Further, by using the edging portion and inserting it into the slit portion provided in the frame of the display device, it is possible to easily combine them. When the slit portion of the frame is vertical, the laminated image unit can be dropped, and the horizontal slit portion can be easily assembled by sliding from the left and right.

[0019]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, two identical images are correctly positioned and overlapped to form an image sheet, and a strong transparent plate or a light diffusing plate, which is larger than the image sheet, is laminated on the front and back sides of the image sheet for pressure bonding. Since the image unit is formed into a small size, it is possible to provide image protection and rigidity, and it is possible to easily handle a relatively large image unit for display.

By providing an edge portion which is larger than the image sheet in the peripheral portion, it can be inserted into a gap provided in the frame of the display device for display or used as an advertisement image.
