Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotor sign device attached to a customer service panel of a vending machine.

Conventional technology The rotor sign device installed below the customer service panel and in the background of the samples arranged on the sample display shelf is
For example, as shown in FIGS. 9 and 10, triangular prisms 1a, 1b, 1c ... Are arranged side by side and rotated in unison around the support shaft 2 to change the front surface of each peripheral surface. Therefore, in this case, the display contents can be switched to three types.

Problems to be Solved by the Invention In such a conventional configuration, since the display contents can be switched to only three types, as shown in FIG. 11 and FIG. Prism
3a, 3b, 3c… It is possible to make them, but adjacent square poles
When 3a and 3b, 3b and 3c, ... Are formed with a pitch p of parallel arrangement so as not to hinder rotation, the gap g between the square pillars 3a and 3b, 3b and 3c ,. Bigger than that,
There is a problem that the displayed contents are unsightly.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rotor sign device capable of switching display contents to four types and further reducing a gap g between adjacent prisms.

Means for Solving the Problems The rotor sign device of the present invention is a rotor sign device that rotates the prisms so that the peripheral surfaces of the prisms arranged in parallel appear on the front of the vending machine and switches the display contents. The prismatic body is a quadrangular prism, and a concave portion that allows the apex of an adjacent prismatic body to escape is formed on each peripheral surface, and the rotation timing of the adjacent prismatic body is shifted.

Operation According to this configuration, the square pillars arranged in parallel do not rotate at the same time, for example, after every other square pillar rotates 90 ° at the same time and stops, the square pillars between them rotate 90 °. When configured to stop, the pitch of the parallel arrangement can be reduced to a position where the apex of the square pillar does not contact the surface of the adjacent square pillar.

Further, the prismatic body is a quadrangular prism, and a concave portion is formed on each peripheral surface thereof to allow the apex of the adjacent prismatic body to escape, and the apex of the adjacent rectangular prism passes through the concave portion.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 8. It should be noted that components having the same functions as those of FIGS. 11 and 12 showing the conventional example are designated by the same reference numerals and described.

1 and 2 show the principle of the rotor sign device of the present invention. The square pillars 3a, 3b, 3c ... arranged in parallel have a first state in which every other square pillar 3b, 3d ,. Quadrangular prism
The switching of the display is executed in two steps, that is, the second state in which the 3a, 3c, ... With such an adjacent square pole 3a
Since the timing of rotation is staggered in 3b, 3b and 3c, ...
Regarding the quadrangular prisms 3a, 3b and 3c, the pitch p of the parallel arrangement can be brought close to the point where the apex 4 of the quadrangular prism 3b does not contact the surface 5 of the quadrangular prisms 3a, 3c. Therefore, the gap g can be made smaller than that in the case where they are all rotated at the same time, and the displayed contents are easy to see. In addition, as a concrete drive device for shifting the rotation timing of the adjacent square pillars, separate power sources are provided for the square pillars 3a, 3c, ... And the square pillars 3b, 3d ,. It can be easily realized by connecting between the support shafts 2 of the square poles by at least one of a gear, a belt or a link mechanism.

In the above principle diagram, the surface 5 of the quadrangular prisms 3a, 3b, 3c ... Is flat, but when the recess 6 is formed in the surface 5 as in the embodiment shown in FIGS. The pitch p can be made smaller than that in the principle diagrams shown in FIGS. 1 and 2,
The gap g can be made smaller.

FIG. 5 and FIG. 6 show a structure in which the symbol sheet 7 representing the display content is detachably attached to the square pole 3a, and here the concave surface 6 is shown.
Corresponding to the above, as shown in FIG. 6, a transparent synthetic resin plate 8 bent into a substantially cylindrical shape is put on the quadrangular prism 3a. As a result, the design sheet 7 between the synthetic resin plate 8 and the quadrangular prism 3a is pressed against and held by the concave surface 6 of the quadrangular prism 3a by the reaction force of the synthetic resin plate 8. Each of the square pillars 3b, 3c, ... Is covered with a synthetic resin plate 8 and holds the design sheet 7.

In the above-mentioned embodiment, the pattern sheet 7 is held on each surface 5 by one synthetic resin plate 8 which is bent into a substantially cylindrical shape with respect to one quadrangular prism. This is as shown in FIG. The holder 9 is attached to, and the rectangular synthetic resin plates 10a to 10d are respectively inserted between the holders 9,
The same applies when the pattern sheet 7 is pressed by the reaction force of the inserted synthetic resin plate.

In each of the above-mentioned embodiments, the concave portion 6 of the quadrangular prisms 3a, 3b, 3c, ... Is formed of a smooth curved surface. However, as shown in FIG. 8, the concave portion 6 is formed by the combination of the flat surfaces 11a and 11b. The same applies to the case.

EFFECTS OF THE INVENTION As described above, according to the present invention, since the prisms arranged in parallel are square prisms, the number of display contents to be switched can be increased by one, compared with the prismatic prisms having four prisms. further,
Since the configuration is made such that the rotation timings of the adjacent prismatic bodies are shifted, the gap between the prismatic bodies being displayed can be reduced and the displayed contents can be easily viewed.

Further, when the prismatic body is a quadrangular prism and a concave portion is formed on each peripheral surface to allow the apex of the adjacent prismatic body to escape, the gap between the prismatic bodies being displayed can be further reduced, and the displayed contents can be more easily viewed. You can do it.
