The part of the laminated film on which the display of characters, figures, symbols, paintings, photographs, etc. is printed or drawn in advance, or the part of the laminated film to be drawn such an indication, that is, the display part of the laminated film is a laminated film. It is exposed to the outside world by feeding out. The fed laminated film is restored to the initial winding state by the residual stress, and the display portion of the laminated film is accommodated in the laminated film roll.

  According to the above configuration of the present invention, it is possible to provide a display device having a simple and inexpensive structure provided with a wound product capable of feeding out a display film displaying characters, figures, symbols, pictures, photographs and the like.

  According to a preferred embodiment of the present invention, a wound product obtained by winding a laminated film around a shaft member is accommodated in the housing, and an opening for drawing the laminated film from the laminated film wound material and drawing it out of the housing is provided. Formed on the housing.

  According to another preferred embodiment of the present invention, the laminated film rolls are arranged in parallel, the laminated films of each roll are stretched between the rolls, and the stretched portion of the laminated film is pressed. Film developing means is provided. A guiding means for turning the laminated film may be disposed between the film developing means and the laminated film roll, and the film developing means is constituted by a flexible membrane member that expands by enclosing an arbitrary fluid.

  FIG. 1A is a partially enlarged cross-sectional view of a laminated film illustrating the structure of a laminated film roll used in the present invention, and FIG. 1B and FIG. It is a perspective view which shows the mode at the time of delivery of a thing, and winding-up.

  FIG. 1A illustrates a cross-sectional structure of the laminated film 10. The laminated film 10 is composed of a laminated film having a multilayer structure or a multilayer structure in which the first layer 11, the second layer 12, the surface layer 13, and the back layer 14 are integrally laminated by a laminate film manufacturing method. Each layer 11-14 consists of a thin resin film made of a resin such as polyethylene, PET, or polypropylene. As desired, the first layer 11 or the second layer 12 is made of a metal vapor deposition film in which a metal thin film 15 such as an aluminum vapor deposition film is formed on a resin film. Since the basic manufacturing method itself for manufacturing a laminated film in which various films are bonded in this manner is already known, detailed description on the basic manufacturing method is omitted.

  Here, the laminated film 10 used in the present invention is formed by controlling the tension acting on the first layer 11 and the second layer 12 in the laminating process so that residual stress acts on the laminated film 10. is there. That is, the tensions P1 and P2 acting on the first layer 11 and the second layer 12 in the laminating process are set to different values, and the optimum values of the tensions P1 and P2 are obtained by integrally laminating the layers 11 to 14. The relationship is set such that the prestress remains in the laminated film 10 after releasing the tensions P1 and P2.

  The laminated film 10 thus manufactured is wound around a spindle 20 having a circular cross section with the surface layer 13 facing the outer surface, for example, as shown in FIG. It is formed around the support shaft 20. The support shaft 20 includes a fixed shaft 21 and a rotation shaft 22 supported on the fixed shaft 21 so as to be freely rotatable. The rotation shaft 22 rotates about the fixed shaft 21. One end (inner end) of the laminated film 10 positioned at the winding inner end is fixed to the rotary shaft 22 by an adhesive or a locking tool, and the other end (outer end) of the laminated film 10 is fixed to the winding roll 30. Located on the outer surface.

  The residual stress generated in the laminated film 10 by the above-described manufacturing tensions P1 and P2 is set so as to be eliminated (balanced) when the laminated film 10 is deformed into a winding state as shown in FIG. Yes.

  When the laminated film 10 is pulled out with fingers as shown by an arrow in FIG. 1B, the rotating shaft 22 rotates around the fixed shaft 21. As a result, the laminated film 10 is fed out from the laminated film roll 3 as shown in FIG. When the fingers are released from the laminated film 10 and the tension of the laminated film 10 (the pulling force applied to the laminated film 10 with fingers) is removed, the laminated film 10 is caused by internal stress existing in the laminated film 10, that is, residual stress. Then, an attempt is made to restore the initial state (the winding state shown in FIG. 1B). For this reason, as shown by the arrow in FIG. 1C, the laminated film 10 is wound around the laminated film roll 3 while rotating the rotating shaft 22 and restored to the initial state.

  In the portion of the laminated film 10 exposed at the time of feeding, characters, figures, patterns, etc., such as advertisements / advertisements, are printed or drawn in advance, and this is the surface layer that is exposed when the laminated film 10 is drawn. 13 as a display 35 is visually recognized from the outside.

  Therefore, the display device provided with the laminated film roll 3 configured as described above does not have any special urging means or driving means for forcibly rotating the winding shaft, and the sheet or film is partially special. The display 35 can be selectively displayed in accordance with the feeding operation or winding operation of the laminated film 10 without replacing the structure.

  Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to FIGS.

  FIG. 2 is a cross-sectional view and a partially broken perspective view showing the configuration of the display device according to the first embodiment of the present invention.

  The display 1 includes a rectangular housing (housing or casing) 2 and a laminated film roll 3 housed in the housing 2. The housing 2 is fixed to a support 5 such as a wall by fixing means 4 such as a fastener, an adhesive, an adhesive, and a suction cup. A slit-like opening 6 for pulling out the laminated film 10 is formed in the bottom wall 2 a of the housing 2. The laminated film roll 3 includes a laminated film 10 wound around a support shaft 20, a fixed shaft 21 and a rotary shaft 22 that constitute the support shaft 20, and a gripping portion 17 that can be gripped with fingers.

  Both ends of the fixed shaft 21 are fixed to the left and right end walls 2 b of the housing 2 and pass through the center of the rotating shaft 22. The rotating shaft 22 is supported in a loosely fitted state around the fixed shaft 21, and the inner end portion of the laminated film 10 is bonded to the outer surface of the rotating shaft 22. The outer end portion of the laminated film 10 passes through the opening 6 and hangs downward from the housing 2. As shown in FIG. 2A, the gripping portion 17 is attached to the leading end portion of the laminated film 10 and is normally positioned at the lower end of the laminated film 10 close to the opening 6.

  When the gripping part 17 is pulled downward with fingers, the rotating shaft 22 rotates around the central axis of the fixed shaft 21, and the laminated film roll 3 feeds the laminated film 10 correspondingly. As a result, the laminated film 10 is drawn downward from the opening 6 as shown in FIG. Anchoring means 8 such as a locking tool, an adhesive, and a suction cup for anchoring the gripping part 17 to the support 5 is provided on the gripping part 17 and / or the support 5. When the gripping portion 17 is moored to the support 5 by the mooring means 8, the laminated film 10 is stretched between the housing 2 and the mooring means 8 against residual stress, and displays characters 35, figures, patterns and the like 35 (FIG. 1) appears on the surface of the laminated film 10 (on the side opposite to the support 5).

  When the mooring means 8 releases the mooring of the grip portion 17, the laminated film 10 is deformed so as to be wound around the winding roll 30 while rotating the rotating shaft 22 due to the residual stress. When the gripping part 17 is raised to the highest position (FIG. 2 (A)), the laminated film 10 loses its residual stress and stabilizes and stops. Thus, the laminated film 10 is wound up in the initial state shown in FIG.

  3 and 4 are cross-sectional views showing the structure of the display device according to the second embodiment of the present invention.

  As shown in FIG. 3A, a plurality of laminated film rolls 3 can be connected by a laminated film 10. When the support shafts 20 are separated from each other as shown in FIG. 3 (B), the laminated film 10 is stretched between the laminated film rolls 3 against the residual stress, and displays 35 of characters, figures, patterns, etc. (FIG. 1) appears between the laminated film rolls 3.

The film developing means 7 is composed of a member that presses the laminated film 10 by manual operation or the like (for example, a roller-shaped member having a circular cross section).

  As shown in FIG. 4A, when the laminated film 10 is pressed in the orthogonal direction by the film unfolding means 7, the rotating shaft 22 rotates in the feeding direction indicated by the arrow in FIG. The thing 3 pays out the laminated film 10 equally. As a result, the laminated film 10 projects in the pressing direction of the film unfolding means 7, and the display 35 (FIG. 1) printed or drawn in advance on the outer surface of the laminated film 10 appears on the outside of the display tool 1.

  On the other hand, as shown in FIG. 4 (B), when the film developing means 7 is moved in the direction of the initial position (FIG. 4 (A)), the laminated film 10 is indicated by an arrow in FIG. 4 (B) due to residual stress. It winds in the winding roll 30, rotating the rotating shaft 22 in the rotation direction. When the film unfolding means 7 returns to the initial position (FIG. 4A), the laminated film 10 loses its residual stress and becomes stable and rests.

The mooring roller 71 is connected to the fixed shaft 21 of the laminated film roll 3 via a connecting member 77.

  When the gripping member 75 is pulled with fingers and the pulling roller 70 and the laminated film roll 3 are separated from each other as indicated by an arrow in FIG. 5A, the rotating shaft 22 rotates in the feeding direction, and the laminated film winding is performed. The recycle 3 feeds the laminated film 10. As a result, the laminated film 10 is stretched between the pulling roller 70 and the laminated film roll 3 so that the display 35 (FIG. 1) is exposed to the outside. The display tool 1 may be designed to display the display 35 only on one side of the display tool 1 or may be designed to display the display 35 on both sides of the display tool 1.

  On the other hand, when the gripping member 75 is released, the laminated film 10 is wound on the winding roll 30 while rotating the rotating shaft 22 in the rotation direction indicated by the arrow in FIG. At the same time, the pulling roller 70 and the laminated film roll 3 move relative to each other so as to approach each other. When the relative positions of the pulling roller 70 and the laminated film roll 3 return to the initial positional relationship shown in FIG. 5A, the laminated film 10 loses its residual stress and becomes stable and rests.

  When the pulling roller 70 is moved outward as indicated by an arrow in FIG. 6A, the rotating shaft 22 rotates in the feeding direction, and the laminated film roll 3 feeds the laminated film 10. As a result, the laminated film 10 is stretched between the pulling roller 70 and the guide roller 80 as shown in FIG. 6B, and the display 35 (FIG. 1) is displayed. The display tool 1 may be designed to display the display 35 only on one side of the display tool 1 or may be designed to display the display 35 on both sides of the display tool 1.

  On the other hand, when the external force of the pulling roller 70 is released, the laminated film 10 is wound around the winding roll 30 while rotating the rotating shaft 22 in the rotation direction indicated by the arrow in FIG. The display 35 (FIG. 1) between 70 and the laminated film roll 3 is retracted into the display 1. When the relative positions of the pulling roller 70 and the laminated film roll 3 return to the initial positional relationship shown in FIG. 6A, the laminated film 10 loses its residual stress and becomes stable and rests.

  FIG. 7 is a cross-sectional view and a partially broken perspective view showing the display device 1 of this embodiment attached to a ceiling or the like.

  The display tool 1 includes a rectangular housing 2 and a laminated film roll 3 housed in the housing 2. The housing 2 is fixed to a horizontal support, for example, the ceiling 9 by the fixing means 4. When the gripping member 75 is pulled downward with fingers, the rotary shaft 22 rotates and the laminated film roll 3 feeds the laminated film 10. The laminated film 10 is drawn downward from the opening 6 as shown in FIG. When the gripping member 75 is anchored to an arbitrary support by anchoring means (not shown) that stops the gripping member 75 at a predetermined level, the laminated film 10 is formed between the housing 2 and the anchoring means against residual stress. The display 35 (FIG. 1) is displayed on the surface of the laminated film 10. The display tool 1 may be designed to display the display 35 only on one side of the display tool 1 or may be designed to display the display 35 on both sides of the display tool 1.

  When the anchoring of the gripping member 75 by the anchoring means is released, the laminated film 10 is wound around the winding roll 30 while rotating the rotating shaft 22 by the residual stress. When the gripping member 75 is raised to the highest position (FIG. 7A), the laminated film 10 loses its residual stress and becomes stable and rests. Thus, the laminated film 10 is wound up in the initial state shown in FIG.
