[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an advertising device for expanding a sheet displaying an advertising medium, and by winding the sheet around a pair of winding rollers, winding the sheet on a winding roller or unwinding the sheet from the winding roller, switching between different advertising media. The present invention relates to an advertising device for displaying.
[0002]
[Prior art]
An advertising device for extending a sheet displaying an advertising medium is known. There are many advertisement devices that spread this sheet, such as an advertisement device installed on the wall surface or the roof of a building and an advertisement device installed on the entire surface of a truck body.
[0003]
[Problems to be solved by the invention]
The above-described large-sized advertising device that spreads a sheet on which a known advertising medium is displayed simply fixes the spread state of the sheet and displays only one advertising medium for advertisement. In an advertising device having a large display area such as a wall surface of a building, a rooftop, or a vehicle body surface, displaying only one advertisement medium does not effectively use a large display area for advertisement. There is a problem that.
In the past, in order to display different advertising media on this large display area, another sheet displaying the different advertising media had to be prepared, and the sheet was replaced and expanded. is there.
The present invention makes it possible to switch and display a plurality of advertisement media with a time lag without occupying the display area for this advertisement by only one advertisement, thereby making the display area for advertisement effective. It is intended to provide a novel advertisement apparatus which can provide advertisements at low cost.

In addition, the advertising device of the present invention is provided with a pair of parallel drive rollers, each of which is capable of reciprocating or reciprocating by forward and reverse rotation, and a pair of wrapping transmission devices provided at both ends of each drive roller, and A sheet displaying a plurality of advertisement media is stretched between the wrapping transmission devices via an elastic body, and one of the sheets is fed into one drive roller, and the other sheet is put on the other drive roller. When the sheet is displayed in a stretched state, the different advertisement media can be switched and displayed by operating the pair of driving rollers to perform the extension or extension operation. That is, this allows a plurality of different advertising media to be switched and displayed by a single advertising device, and not only can the display area of the advertising device be used effectively, but also the sheet can be prevented from bending and a good spread state of the sheet can be obtained. Can be
[0008]
Furthermore, the advertising device of the present invention is provided with a rotating shaft for both ends tuning inside the pair of driving rollers, and a forward / reverse rotating driving motor at a longitudinal center position of each rotating shaft for both ends tuning and a position between the shafts. The rotational force of the forward / reverse rotation drive motor is transmitted to the both-end tuning rotary shaft via an endless belt or an endless chain, and between both ends of the both-end tuning rotary shaft and both ends of the drive roller via an endless belt or an endless chain. In this case, the rotational force is transmitted to rotate both drive rollers synchronously. In other words, this makes it possible to average the entire surface of the sheet of the relatively large advertising apparatus without biasing the spread state of the sheet.
[0009]
In addition, the apparatus of the present invention is provided with a bending-preventing pressure roller which opposes each driving roller and presses the driven sheet. That is, this also prevents the sheet from being bent, and provides a good spread state of the sheet.
Further, in the apparatus of the present invention, sheet guide rolls are provided in parallel at outer front positions of the respective winding rollers or drive rollers, and are extended via these sheet guide rolls. That is, a display area having a larger width between the pair of winding rollers or the driving rollers can be obtained.
[0010]
Further, the device of the present invention is provided with a guide member for guiding each of the wrapping transmissions. That is, this prevents the wrapping transmission from being distorted toward the seat due to the elastic force of the elastic body. In addition, in the apparatus of the present invention, the wrapping transmission is composed of a chain and a sprocket. That is, by this, the transmission can be transmitted without causing the winding transmission to slip, and the sheet can be evenly rotated without bias.
