Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pop-up type card or book in which a three-dimensional object having a beautiful coloring pops out when a spreadable card or book is opened.

[0002]

2. Description of the Related Art A polarizing plate and a retardation plate are used in a liquid crystal display panel.
By sandwiching more than one retardation plate, various colors can be made to appear according to the retardation value of the retardation plate.
For example, on the cover page of "Nikkei Microdevice, October 1988", a color photograph taken with a retardation plate sandwiched between two polarizing plates is posted.

Utilizing such a property, various applications in which a polarizing plate and a retardation plate are combined have been proposed, and the applicant (or the present inventor) of the present invention has the following applications. I am applying.

(A) JP-A-4-105091 (clock) A polarizing plate is arranged at the rear side of the region surrounded by the side frame, a polarizing plate is arranged at the front side, and a retardation plate is arranged at the center. A timepiece in which at least one of the layers is rotated by the output section of the drive mechanism section installed near the side frame.

(B) Japanese Patent Application Laid-Open No. 4-293889 (Blind) A large number of strip-shaped equal-width polarizing plates whose alignment directions are at right angles to each other are alternately planar so that their long sides are in contact with each other. To form a blind plate, and prepare two blind plates, one of which is the front blind plate and the other of which is the rear blind plate, and these are stacked in front and back, and these are short plates A blind that is configured to be relatively movable in the lateral direction and further has a retardation plate interposed between a front blind plate and a rear blind plate.

(C) Japanese Patent Application Laid-Open No. 4-307300 (stained glass) A phase difference obtained by color matching and cutting according to the design on a substrate made of glass, an optically isotropic film, a retardation plate or a polarizing plate. A stained glass having a structure in which plate pieces are attached in a mosaic shape, and polarizing plates are laminated so that the polarizing plates are located outside both surfaces of the retardation plate piece attached to the substrate.

(D) Japanese Unexamined Patent Publication No. 5-196893 (Membrane-like color space image forming body) An adhesive sheet having a retardation plate adhered and arranged on one surface of a polarizing plate is A film-like color space image forming body is shown which is formed of a tubular body formed inwardly.

(E) Japanese Utility Model Publication No. 5-66615 (Cylindrical body having a three-dimensional pattern) A cylindrical body having a three-dimensional pattern having the same structure as the above (D).

[0009]

The method of combining a polarizing plate and a retardation plate can be expected to be applied to decorations, displays, or practical products that also function as decorations and displays.

However, of the above (A) watches,
In the blind of (B) and the stained glass of (C), although the colors revealed by combining the polarizing plate and the retardation plate are extremely beautiful, there is a limit that they remain flat. (Although it can be rotated or slid).

On the other hand, the film-like color space image forming body of (D) and the cylindrical body having a three-dimensional pattern of (E) are three-dimensional and, in addition, create a virtual image based on the illusion of the eye. It is rich in sex. However, since these use a three-dimensional tubular body as a figurine, etc., the image itself is surprising, but it does not move as a structure (although it can be rotated), and it is bulky. It is also inconvenient in terms of handing over, mailing and storing.

[0012] Under such a background, the present invention is a pop-up type spreader in which a beautifully colored three-dimensional object appears to pop out while it can normally be closed flat, and the color changes richly depending on the viewing angle. It is intended to provide the body.

[0013]

The pop-up spreader of the present invention is made of a polarizing plate consisting of a cylinder or a separating piece by utilizing a fold between both pages of a spreadable substrate (1) or both pages. The outer body (2) is provided so that it can be converted into two states, a folded state and a pop-up state, and when the outer body (2) is a cylinder, the outer body (2) is placed inside the cylinder. When it is a separating piece, the base body in the middle part sandwiched by the separating piece.
(1) It has a structure in which the inner body (3) made of a retardation plate is provided so as to be convertible into two states, a folded state and a pop-up state.

The present invention will be described in detail below.

Examples of the spreadable substrate (1) include cards and books made of cardboard, sheets, cloth, etc., boxes having lids and inner lids, foldable doors, accordion curtains, and the like.

As the polarizing plate constituting the outer body (2), a polarizing element film can be used as it is, but usually, a polarizing element film having a protective layer laminated on at least one surface (particularly both surfaces) thereof is used. Here, as the polarizing film, vinyl alcohol type polymer / iodine type, vinyl alcohol type polymer / dichroic dye type, vinyl alcohol type polymer / polyene type, polyhalogenated vinyl / polyene type, polyacrylonitrile / polyene type System, poly (meth) acrylate / polyene system and the like. In the above, the vinyl alcohol-based polymer is polyvinyl alcohol, ethylene-vinyl alcohol copolymer, or the like. Examples of the protective layer include optically isotropic transparent films such as a cellulose triacetate film, a polycarbonate film and a polyarylate film.

The outer body (2) made of a polarizing plate is formed of a cylindrical body forming a polygonal cylinder such as a square cylinder, a hexagonal cylinder, an octagonal cylinder or the like in a pop-up state, or from two separating pieces separated from each other. Become.

The outer body (2) made of this polarizing plate can be converted into two states, a folded state and a pop-up state, between the left and right (sometimes upper and lower) pages of the base body (1) which can be opened. It is provided by using the fold line or both of its left and right pages (which may be upper and lower). In this case, the outer body for the substrate (1)
A suitable support piece (4) for supporting the outer body (2) may be used to facilitate the support of (2) and pop-up.

The retardation plate constituting the inner body (3) includes polyvinyl alcohol, ethylene-vinyl alcohol copolymer, polycarbonate, polyvinyl chloride, polyarylate, polymethylmethacrylate, polyolefin, polystyrene and polyester. There is used a molecularly oriented retardation film made of various polymers described above or a laminate of the above-mentioned protective layer on at least one surface thereof. The molecular orientation is usually performed by stretching in a uniaxial direction, but in some cases, it may be stretched in a biaxial direction or a triaxial direction. The stretching ratio is often about 1.1 to 5 times, and after stretching, heat setting and aging are appropriately performed.

The retardation value of the retardation plate is preferably selected from the range of about 30 to 1000 nm, and may be set in other ranges. Transparency (visible light transmittance) is 6
It is preferably 0% or more. In order to adjust the retardation value of the retardation plate, two or more retardation plates may be laminated and used.

The shape of the inner body (3) has various shapes which become a solid in a pop-up state. In this case, it is also possible to make various pieces of the retardation plate, make appropriate cuts, and engage the pieces so that the pieces are engaged with each other at the cut portions. It is also possible to make the inner body (3) move by providing a devised fold in or providing an appropriate operation piece.

When the outer body (2) described above is a cylinder, the inner body (3) made of the retardation plate is inside the cylinder and the outer body (2) is a separating piece. At this time, it is provided on the intermediate body (1) sandwiched by the separating pieces so as to be convertible into two states, a folded state and a pop-up state. In this case, the external body
A suitable support piece (4) for supporting the inner body (3) may be used to facilitate the support of the inner body (3) to the (2) and the substrate (1) and to facilitate pop-up.

In the pop-up state, the inner body (3) made of the retardation plate is placed on the front side of the outer body made of a polarizing plate.
You will see through (2) and the outer body (2) made of a polarizing plate on the other side. In this case, the outer body made of polarizing plate on the front side
The orientation direction of (2) and the orientation direction of the outer body (2) made of a polarizing plate on the other side are often orthogonal to each other, and the orientation direction of the inner body (3) made of the retardation plate Also, it is preferable to adjust accordingly to obtain good color development.
When trimming the pieces for the outer body (2) and the inner body (3) from the original polarizing plate and the original retardation plate, respectively, pay attention to the orientation direction. Of course, it can be sufficiently used even if it is not orthogonal.

The pop-up spread body of the present invention is manufactured by taking the above-mentioned arrangement relationship. A typical example of such a spread body is a pop-up greeting card (a greeting card, a card to be sent for Christmas or birthdays, or a gift card), or a pop-up book (a book that pops up when opened). ) Or a trick book.

To the pop-up spreader, it is possible to add a device such as playing music, emitting light, or generating a scent when the spread is opened.

[0026]

In the pop-up spreader of the present invention,
Since the outer body (2) and the inner body (3) are in the folded state when the base body (1) is closed, the entire body becomes flat, and manual handling, mailing, and storage can be easily performed.

On the other hand, when the base body (1) is opened, both the outer body (2) and the inner body (3) are in a pop-up state, and in this state, the inner body (3) is the outer body (2). Located inside or in the middle of. Therefore, when viewed from the outside, although they are spatially separated, the inner body (3) made of the retardation film is in a positional relationship sandwiched by the outer body (2) made of the polarizing plate. The inner body (3) looks beautifully colored. And the retardation value changes where the pieces of the retardation plate that compose the inner body (3) appear to overlap each other in a double or triple manner (if the orientation direction of the retardation plate is the same, the retardation value is added And is subtracted when the orientation directions are orthogonal to each other), so that they have different colors.
Therefore, if you change the viewing angle (slightly shift the angle),
You can enjoy rich color changes.
