The present invention has a structure that can be used as an advertising display device, which reduces costs by reducing the number of leaves, and allows easy attachment and replacement of leaves.

である。 2. Description of the Related Art Conventionally, there has been a display device of a falling and reversing type with a display leaf as shown in FIGS. 1 and 2. In this system, the display contents of 24 to 60 pages are displayed in cooperation with two display leaves, one above the other. Such conventional technology requires a large number of display leaves (hereinafter referred to as leaves) of about 24 or more, and when used for advertising that requires display conversion from 4 pages to 6 pages, the problem shown in Fig. 3 a. As shown, the state in which the upper leaf A ₁ rotates toward the front can be seen from the position where it falls backward, which is not practical. This is because one leaf A hits the pawl 2 at the top of the machine frame 1 and faces completely forward, and then the bobbin rotates and the open side of leaf A comes off the pawl 2 and turns over at a slight angle. This is because only bobbin rotation is allowed, and when there are only a few leaves, there is a limit to the deflection of the leaves and the front-facing display time ratio decreases.

そこで第３図ｂのように正常な表示を行なわせ

辺には５か所の軸受孔B₂がある。 Fig. 4 shows the state immediately before the leaf A5 in Fig. _3b falls and reverses, and the same state is illustrated in Fig. 6. There is a bobbin B rotating at a low speed by a drive source. There are five bearing holes _B2 around the left and right bobbin flanges _B1 .

Ａに取り付けた構成である。 On the other hand, Leaf A has a double structure in which the plastic display panel 3' that forms the display surface on the front side is bent at the rotation axis side of Leaf A to form the display panel 3'' on the back side, and the bent portion of the display panel 3 In order to protrude as the rotation axis of the left and right leaves A, make it the leaf shaft part 4, and reinforce the shaft part 4,
The steel wire 5 is connected to the display face plate 3 on the rotation axis of the leaf A.
Glue and fix it to the leaf A, and further along the rotation axis of leaf A,
A spring wire 6 is rotatably stored between the double front and back display panels 3' and 3'', one end of the spring wire 6 is bent and fixed to the display panel 3 with adhesive, and the spring wire 6 is The other end is bent in the direction away from the rotational axis of leaf A at the point where it exits near the shaft portion 4 of leaf A to form a spring rod 6', and a receiving part 7 for securing the fulcrum position of the spring rod 6' is attached as described above. This configuration is attached to leaf A at the outlet of the spring rod.

Ａに対応して５個の突起部B₃が設けられている。 Five such leaves A are fitted into each shaft part 4 in each bearing hole B ₂ of the left and right bobbin flanges B ₁ , and when each leaf A wraps around to the back side with the rotation of the bobbin B, the leaf A There are protrusions B3 around the bobbin flange _B1 against which the spring rods 6' of the leaves are pressed in the direction of lifting the leaf, and five protrusions _B3 are provided corresponding to the five leaves A. .

る。 Now, when _the bobbin B is rotated by an arbitrary drive source such as an electric motor with a speed reducer and reaches the position shown in _Figs . show
The leaf A ₄ is being displayed facing the front side (right side of the figure), and its spring rod 6' is not pushed by the protrusion B ₃ and the leaf is being displayed as in the conventional leaf type display device.
By bending A ₄ , it can be freely attached and detached from bobbin B. At this time, leaf A ₅ is displayed on the front side, so it is possible to attach and detach it from the front side, but it is somewhat difficult because its spring rod 6' is strongly pressed against protrusion B ₃ . The spring wire 6 has a torsional deflection angle of approximately 100° between the joint portion of the display face plate 3 and the spring rod 6', and generates a torsional stress that tends to flip the leaf A ₅ toward the front side.

から離れ、自由なリーフの脱着ができる。 Next, if the bobbin B rotates a little, the open end of the leaf A ₅ will come off the claw part 2 provided at the top of the window of the machine frame 1 shown in FIG. _A5 is turned over while falling to the front side, falls to the position shown by the two-dot chain line in Fig. 6, and displays a display on the front side that cooperates with the leaf display of _A1 . At this time, the spring rod 6' of the leaf of A ₅ is located at the protrusion B ₃
The leaf can be attached and detached freely.

ーフの直立待期によつてもたらされている。 Next, bobbin B rotates a little further, and the leaf of A ₄ tries to wrap around from the bottom side to the back side, and when it comes to the leaf position of A ₄ shown by the three-dot chain line in Fig. 6, the protrusion B ₃ begins to hit the spring rod 6' of leaf A ₄ , and as the bobbin B rotates, the protrusion B ₃ starts to push the spring rod 6' in the direction that lifts the leaf A ₄ on the back side, as shown in Figure 6. The leaves that have come to the back side like A ₁ and A ₂ are all lifted by the torsional stress of the spring wire 6 in the same direction as the rotation direction of the bobbin B, and the leaves A ₁ in the figure
When the leaf comes to the upper side, such as the leaf shown in FIG. Therefore, when the leaf displayed on the upper side is reversed, as in the case where the leaf _A5 falls to the position indicated by the two-dot chain line in the figure, the display shown when the number of leaves is simply reduced on a conventional leaf-type display device is An upright display in a position that is easy to see on the front side without making the surface difficult to see is provided by the upright position of the upper leaf, such as Leaf _A1 .

することもできる。 In the present invention, the leaf shaft portion 4 is made of two sheets, as shown in FIG. 7, in which a steel wire 5' is protruded to the left and right on the center line of rotation of a rectangular leaf, and a plastic core material 8 for maintaining the distance is joined together. It can also be implemented as a double structure with the display face plates 3', 3'', and the core material 8
It is also possible to extend both ends of the leaf so that they protrude to the left and right of the leaf, thereby forming a leaf shaft. Alternatively, the leaf may be made of injection molded plastic, and the spring rod receiving part 7, the spacing core 8, etc. may be integrally formed.

である。 As described above, according to the present invention, normal display can be performed on the front side even with only a few leaves, and by reducing the number of leaves, a low-cost display device for advertising can be provided.
The leaf can be attached and detached integrally with the spring rod, and there is no need to adjust the spring, making it easy for even amateurs to do so. According to the season or advertising requirements of the day, only the leaf that needs to be changed in display content can be replaced. Or, while rotating the bobbin with a driving source, replace the fallen and reversed leaves one after another with the leaves with the new advertising text.
Since all the leaves can be replaced, it is practical for advertising purposes, and is highly useful as it is easy to assemble and can reduce production costs.
