Description

[Detailed description of the invention] Industrial application field] The present invention is a system for circulating multiple advertising posters by installing them in public transportation vehicles such as trains and buses, or in public buildings such as stores and underground passages. This invention relates to a poster circulation display device that sequentially updates and displays posters.

[Prior Art] Conventionally, for example, in public transportation vehicles such as trains and buses, a ceiling-hanging poster display device as shown in FIG. 14 has been used.

This type of conventional ceiling hanging poster display device supports a main rod (62) on the ceiling (C) of a train etc. via a bracket (61), and a pair of clamping plates (61) are attached to the main rod (62). 63) so that it can be opened and closed, and a poster (P) is sandwiched between the clamping plate (63) and the main rod (62) so that both sides of the poster (P) can be displayed to passengers inside the car. It was configured.

[Problem to be solved by the invention] However, since the conventional ceiling-hanging poster display device is configured as described in 1., there is a restriction on the number of posters (P) that can be displayed, and there is a limit to the advertising capacity. .

Furthermore, since the same poster (P) is likely to be displayed in the same place for a long period of time, passengers may become bored with the poster, and the advertising effectiveness will decline over time. Moreover, because the poster (P) was displayed in a stationary state with little variation, passengers often only glanced at the poster (P), and a sufficient advertising effect could not be expected. .

Therefore, the object of the present invention is to provide a poster circulation display device that can efficiently display a large amount of advertisements in a narrow space, and that can arouse the attention and interest of viewers and perform varied and effective advertisements. It is about providing.

[Means for Solving the Problems] A poster circulation display device according to the present invention includes a support means for supporting a plurality of holders on which posters are hung in parallel in a substantially horizontal plane, and a support means for supporting a plurality of holders from which posters are suspended, from the front end to the rear end of the support means. It is comprised of a conveyance path formed in a substantially annular shape so as to extend, and a conveyance means that sequentially conveys the holder at the forefront of the support means along the conveyance path to the rearmost portion of the support means.

[Operation 1] In the present invention, a plurality of posters are hung in parallel from a support means via a holder, and in this state, an advertisement is displayed on the front of the frontmost poster. Then, when this poster at the forefront is conveyed along with the holder to the rearmost portion of the supporting means by the conveying means, an advertisement on the rear side of the poster is displayed.

Therefore, by repeating this circulation operation, a plurality of posters are updated and displayed one after another.

Therefore, a large amount of advertisement can be displayed efficiently in a small space, and the circulation movement of the poster can arouse the attention and interest of viewers, making it possible to carry out a variety of effective advertisements. Furthermore, since the poster is conveyed along the annular conveyance path, there is no risk of the poster becoming curly.
