Since the illusion lamp is incorporated in other items such as animal figurines and stuffed animals, the display film surface display is enlarged and projected from the other items to the wall or screen. It can be seen by humans and is suitable for increasing the added value of other items.

Next, an embodiment of how the multi phantom lamp according to the present invention is practically described will be described. FIG. 1 is a front view for explaining the basic structure of a multi-illusion lamp according to the present invention. is doing. In this magnifying tube 2, a magnifying convex lens L is incorporated near the upper end.
The display film surface 1 is a medium for displaying information such as images viewed by a plurality of people by projecting on a wall surface or a screen with a phantom lamp, and is displayed in advance on a transparent film or the like by photographic technology or the like And
The support surface 3 and the support shaft 4 of the drive wheel W are attached and supported by a rectangular frame f shown in FIG. FIG. 2 is a cross-sectional view in the AA direction of FIG.

The large-diameter drive wheel W and the small-diameter support wheel ω are integrated, and rotate about the support shaft 4 supported by the frame f.
The endless belt-like body 5 is wound around the support wheel ω and the support surface 3 like a transmission belt. When the support wheel ω is rotated by the drive wheel W, the belt-like body 5 reciprocates in the direction of the arrow a1. Is done.
The support surface 3 is a flat surface facing the lower end of the expansion cylinder 2, and the display film surface 1 arriving at the center of the support surface 3 is held in the expansion cylinder in a state where the flexible belt-like body 5 is held flat. 2 is projected on the wall or screen, etc. so that it can be seen by multiple people.

The belt-like body 5 has a photographic negative film shape or a belt-like shape made of rubber or soft synthetic resin, and has a display film surface 1 such as a photograph at a constant pitch. Therefore, by rotating the driving wheel W with a finger and moving the belt-like body 5 in the direction of the arrow a1 with the support wheel ω, the display film is transferred to the position of the magnifying tube 2 in the state where the desired display film surface 1 is transferred. Since the display of the surface 1 is projected on the wall surface or the screen in a state of being magnified by the lens L, it can be viewed by a plurality of people.

As shown in FIG. 2, the support surface 3 has a window hole 3 h formed in a region through which the belt-like body 5 passes so that the light emitted from the backlight r can pass therethrough. Therefore, since the display film surface 1 is projected from the back side, it is magnified and projected on the wall surface or screen by the magnifying tube 2 and displayed clearly.
The backlight r in the illustrated example is made of a semiconductor such as a light emitting diode, but is not particularly limited as long as it is an element that emits light. A miniature light bulb may be used, but the power consumption is large. E is a battery, preferably a small size such as a button battery or a film battery. A condensing lens 6 may be provided between the light source r and the window hole 3h.

A support cylinder 7 is integrally formed on the inner side of the support surface 3, and a light emitting body r for backlight is inserted and supported therein from the back. Therefore, the battery E is also supported by the support cylinder 7. The support cylinder 7 may be a cylinder or a square cylinder.
Guide plates 8 and 8 of the belt-like body 5 are suspended from the outside of the support cylinder 7, and the support surface 3 is located between the guide plates 8 and 8 and the upper end of the support cylinder 7.
Therefore, the belt-like body 5 reaches the support surface 3 while being guided by the front and rear guide plates 8 and 8, and the desired display film surface 1 arrives at the lower end position of the expansion cylinder 2. If the space between the guide plates 8 and 8 and the support surface 3 is angular, the smooth running of the belt-like body 5 will be hindered. Therefore, it is desirable to make the curved surface as large as possible.

1 is hidden by a frame f in FIG. 2 so that the inside of the belt-like body 5 in FIG. 1 cannot be seen from the outside. That is, the guide plates 8 and 8, the support cylinder 7, the battery E, the drive wheel W, and the support wheel ω are built in the rectangular frame f.
The belt-like body 5 is exposed except in the region of the support wheel ω, but it is also possible to cover all except the display film surface 1.

In the case of FIG. 1 and FIG. 2, since the support surface 3 and the expansion cylinder 2 are separated, the interval and direction between the display film surface 1 and the expansion cylinder 2 are free. Inconvenient.
On the other hand, as shown in FIG. 3 and subsequent figures, the expansion cylinder 2 can be attached and fixed to the frame f side by adopting the connecting rectangular cylinder 9.

3 is a front view, FIG. 4 is a right side view, and FIG. 5 is a longitudinal sectional view in the BB direction of FIG.
As is apparent from FIG. 5, a rectangular tube 9 is provided to cover and cover the upper side of the frame f, and covers the front, rear, left and right of the frame f.
A receiving hole 9h into which the expansion cylinder 2 can be inserted is formed in the ceiling surface 91. Therefore, the expansion cylinder 2 is held by the square cylinder 9 by inserting the expansion cylinder 2 from above into the receiving hole 9h.
As shown in FIG. 1 and FIG. 2, the large diameter stopper 2s is formed on the outer periphery of the expansion cylinder 2, so that positioning when inserting into the receiving hole 9h is easy. The distance between the lower end of the display and the display film surface 1 is kept exactly constant.

As shown in FIG. 3, the rectangular tube 9 covers only the upper side of the frame f, so that the inside of the frame f is exposed on the lower side. As indicated by a chain line 92, the rectangular tube 9 can be extended to the lower end of the frame f so as to hide the entire frame f from view. In this case, needless to say, the large-diameter driving wheel W is exposed through the slit.
An operation button 10 is provided and held on the frame f so that the power switch SW of the battery E can be operated from the outside. The operation button 10 may be a push button type or a slide type.

As shown in FIG. 4, the belt-like body 5 shown in FIGS. 1 to 5 is formed by, for example, opening rectangular window holes H at regular intervals and attaching display sheets or films to the respective window holes H. The surface 1 can be formed.
Each display film surface 1 may be adhered and fixed to the belt-like body 5 with an adhesive, or a transparent belt-like film is stacked on the outside of the belt-like body 5 and each display film surface 1 is sandwiched therebetween. , May be held.
By positioning positioning pins formed on both sides of each window hole H into receiving holes opened on both sides of each display film surface 1, positioning and mounting support are possible.
Thus, in the case of the configuration in which each display film surface 1 is disposed in each window hole H, a large number of individual display film surfaces 1 are prepared, and the desired display film surface 1 can be set to an arbitrary window. Can be installed in holes H.

As shown in FIG. 5, since the protrusions 11 provided on the outer periphery of the support wheel ω at the predetermined intervals bite into the inner surface of the belt-like body 5 to prevent slipping, slipping is prevented and each display film surface is reliably expanded. 2 positions can be supplied. Making the outer peripheral surface of the support ring ω uneven or rough, or forming the support ring ω in a polygonal shape is also effective for preventing idling, that is, preventing the belt-like body 5 from slipping. A structure in which a pinch roller is provided on the outer periphery of the support wheel ω to sandwich the belt-like body 5 is also effective.

6 to 8, the belt-like body 5 is a film F. In addition, feed holes h are formed at regular intervals on both sides of the endless film F in a square shape or a circular shape.
On the other hand, on the outer periphery of the support wheel ω, feed claws 12 to be fitted into the feed holes h are arranged at regular intervals on both sides thereof.
Accordingly, when the support wheel ω is rotated by the drive wheel W, the feed claws 12 are rotated in a state where they are inserted into the feed holes h of the endless film F, so that the endless film F is reliably fed and a desired display film is obtained. The surface 1 can be supplied to the position of the enlarged cylinder 2.
Needless to say, various display contents are displayed on the endless film F at a predetermined interval (pitch) in advance. The display content may be an image, text information, or a mixture of both.

As another embodiment, the endless film F may be formed of a transparent body having high transparency, and each display film surface described with reference to FIGS.
The attaching method may be adhesion, or two transparent films F may be stacked and each display film surface may be sandwiched between them. In this case, in order to partition at a constant interval, it is convenient to bond only two partition portions of the two transparent films F and F at a constant interval.

Since the belt-like body 5 and the endless film F described above rotate continuously, it is difficult to accurately stop the display film surface 1, that is, the desired display film surface, at the position of the enlargement cylinder 2. May stop at. As a result, it is necessary to visually determine the stop position while projecting and displaying the display film surface 1 with the magnifying tube 2, which is inconvenient.
On the other hand, in the case of FIG. 9, since the arcuate protrusions 15 at the tip of the leaf spring 14 are fitted into the arcuate depressions 13 formed at regular intervals on the side surface of the support wheel ω, The support wheel ω can be stopped accurately at the position.

As a result, if the position of the recess 13 of the support wheel ω and the center position of each display film surface reaching the center of the window hole 3h are made to correspond to each other, the protrusion 15 at the tip of the leaf spring 14 is fitted into each recess 13. The center of each display film surface always arrives at the center position of the magnifying tube 2 and stops.
In this case, it goes without saying that the intervals between the depressions 13 are made to coincide with the intervals between the display film surfaces. In addition, you may provide the hollow 13 ... in the outer peripheral surface of the support wheel (omega).

In FIG. 9, the base of the leaf spring 14 is fixed and attached to the inner surface of the frame f. However, as shown in FIG. 6, a U-shaped slit 16 is formed in the frame f itself, and the inside thereof is attached to the leaf spring 14. You can also In this case, it is a matter of course that the thickness of the frame f is reduced or the material is rich in elasticity so as to ensure the elasticity as the leaf spring 14.

As described above, a plurality of displays can be enlarged and projected continuously or intermittently by driving a belt-shaped body made of soft rubber or film and supplying a desired display film surface to the position of the expansion cylinder. Since it can be viewed by multiple people at the same time, when it is attached to various straps, key holders, bags, etc. and used as love toys or jewelry, it can be viewed and enjoyed by multiple people by expanding the desired display. Will increase.
In addition, if a large amount of display information is mass-produced using a belt-like body to produce various contents, it can be effectively used as teaching materials or business equipment. It is also useful as a guide for sightseeing spots and various events, as a souvenir, or as a memory.
This illuminator may be used alone, but it is built in animal figurines, stuffed animals, and other items, and the display on the display film surface is projected from various items onto the wall or screen. It is suitable for increasing the added value of other products.
