Abstract

PURPOSE: To eliminate wear and tear of display films and to simplify the structure by making diameters of guide rolls different by display films and coaxially attaching them so that they can be relatively rotated. CONSTITUTION: Guide rolls 27a and 27b have diameters different by respective display films 12 and 13 and are relatively rotatably attached on the same shaft 24. Consequently, display fulms 12 and 13 are relatively moved, and displays recorded on display films 12 and 13 are combined to easily display, for example, a price in many display steps, thereby copying with the variance of the price. Since display films 12 and 13 are guided by guide rolls 27 and 27b different by diameters in this manner, they don't come into contact with each other and are protected from wear and tear; and since guide rolls 27a and 27b are supported on the same shaft, the structure is simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a display device that is installed at a filling station such as a gas station and displays, for example, the price of gasoline in an advertising manner.

[Prior Art] Many of these display devices are internally illuminated with fluorescent lights for reasons such as the ability to see clearly at night and the freedom to use fonts.In this case, in order to display effectively, teeth,
It is preferable to install it in a place higher than the ground, for example, on the top of a sign ball facing the road. Therefore, when changing the price, it is preferable to use a remote control method from the viewpoint of workability.

In addition, the fl rating of the oil type displayed at gas stations is often
Since it is displayed in 3 digits, 10 can display 0 to 999 yen.
If you use a film with 00 step numbers printed on it,
Weight and storage size increase.

For this reason, prices are often displayed using film with numbers printed in 100 steps from 100 to 199 yen.In this case, if the price falls outside the set price range, it cannot be used, and the film Replacement is troublesome as it requires work at heights, and it is impossible to respond to price fluctuations.

In contrast, in Japanese Patent Application No. 62-109882, the present applicant has provided first and second films that are overlapped and are movable relative to each other in the longitudinal direction, and the first film has, for example, oil type and price. Enter the first display symbol of the digit,
A second display symbol of the 10th and 100th digits of the price is written in a part of the second film other than the display symbol written part of the first film, and the first and second display symbols are combined. proposed a price display device that displays prices in many display steps.

This proposal itself is effective, but since the first and second films are overlaid, both films may become skewed over time, and since guide rollers are provided for each film, The structure is complex.

[Object of the Invention] Accordingly, an object of the present invention is to provide a price display device with a simple structure, which does not cause damage to the display film and has a minimum number of guide roller shafts.

[Structure of the Invention] According to the present invention, in a display device in which a plurality of display films are wound onto and unwound from each take-up reel via a guide roller, the guide roller has a different diameter for each display film, and are coaxially mounted so as to be relatively rotatable.

[Operations and Effects of the Invention] Therefore, by relatively moving each display film, and by combining the displays written on each display film, it is possible to easily display, for example, a price in many display steps, and to respond to price fluctuations. In addition, since each display film is guided by guide rollers of different diameters, they do not come into contact with each other, preventing damage to the two, and since each guide roller is supported coaxially, The structure is simplified.

Moreover, by overlapping each film, internal illumination light is prevented from leaking to the outside through the gap between both films.

[Preferred Embodiment] In carrying out the present invention, it is preferable that the difference in the outer diameters of both guide rollers is, for example, about 4a+a, and the amount of overlap between both films is, for example, 10 m.
