Beverages accounted for 40.2%, followed by tobacco (24%). It is common for consumers to view advertisements (commercial) of products on mass media such as televisions, radios, and magazines, and purchase memorable products at vending machines. This tendency is particularly strong for new products and products purchased for the first time.

Similarly, a business in which a large number of products are arranged on a display shelf or a display case in a retail store or the like so that the consumer can see them, the consumer selects a desired product, and pays the charge to make a sale. Also in terms of form, mass media such as television, radio, and magazines are often used to advertise products.

In such a case, it is general that the place where the advertisement of the product is viewed is separated from the place where the product is sold by an automatic vending machine or the like. For this reason, even if the consumer is motivated to buy by the advertisement, the product cannot be purchased on the spot.

[0005]

A method of using a poster or the like is generally used as an advertising method on the spot where products are sold. However, poster-based advertising has a problem in that the work of preparing the poster, securing a place to paste it, and replacing it occurs. In addition, in an advertisement using a poster, there is a problem that it is difficult to perform an advertisement near a displayed product and it is difficult to appropriately perform an advertisement corresponding to a specific product.

[0006] With the above-described advertising method, it is difficult to advertise products in a timely manner in a situation where the product lineup of various products displayed in a short period of time is changed one after another. Further, it has been difficult to carry out an advertisement in the vicinity of the displayed product, which is aimed at consumers who have come to purchase the product and stimulates the purchase will.

In view of the above points, an object of the present invention is to provide an advertisement display device capable of advertising a product in the vicinity of the product without requiring a new installation place.

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) A first embodiment of the present invention will be described below with reference to FIGS.
The advertising system according to the first embodiment uses an vending machine as a product display device, and advertises products displayed on the vending machine using a front transparent panel of the vending machine.

FIG. 1 shows the overall schematic configuration of the advertising system of this embodiment. As shown in FIG. 1, the advertisement distribution server 10 and a plurality of advertisement display devices 20 are connected by a communication network 30. As the communication network 30, the Internet, LAN, general telephone network, wireless telephone network or the like can be used. The advertisement distribution server 10 is owned by an advertisement provider that provides advertisements, and the advertisement display device 20 is provided.
Is installed in a vending machine 40 that displays and sells products.

The advertisement distribution server 10 is a server computer. The advertisement distribution server 10 includes software for creating advertisement information, is configured to be able to create arbitrary advertisement information, and to distribute the advertisement information to the advertisement display device 20 via the communication network 30. . The display format of the advertisement information created by the advertisement distribution server 10 can be arbitrarily set, and character information, image information (still image, moving image) and the like can be appropriately combined and used.

FIG. 2 is a block diagram showing a schematic configuration of the advertisement display device 20. As shown in FIG. 2, the advertisement display device 20 includes an advertisement display unit 21 that displays advertisement information and a drive circuit 22 that drives the transparent display 21.
The advertisement display unit 21 is composed of a transparent display having transparency. The transparent display 21 is configured so that the brightness of advertisement display can be arbitrarily adjusted.

In the advertisement display device 20 of the first embodiment,
An illuminance sensor 23 that detects the illuminance of the place where the transparent display 21 is installed, a control circuit 23 that performs various arithmetic processes and controls, and a communication interface circuit (communication means) that communicates with the advertisement information distribution server 10 via the communication network 30. 24 are provided.

The control circuit 24 is provided with a flash memory (storage means) and can store the advertisement information data received from the advertisement information distribution server 10. Further, the control circuit 24 controls the drive circuit 22 to display the advertisement information on the transparent display 21, and the illuminance sensor 23.
The brightness of the advertisement information displayed on the transparent display 21 can be controlled based on the detected illuminance in the vicinity of the vending machine 40.

FIG. 3 is a perspective view showing an installed state of the transparent display 21, and FIG. 4 is a sectional view of the same. Figure 3,
As shown in FIG. 4, the transparent display 21 is provided on the rear surface side of the front transparent panel 41 of the vending machine 40. The consumer can see the product (or its model) 42 through the front transparent panel 41 and the transparent display 21. The transparent display 21 is fixed to the back side of the front panel 41 with a transparent adhesive or a transparent double-sided tape.

As the transparent display 21, an inorganic EL is used.
An inorganic EL display using an (electroluminescence) element, a liquid crystal display, a fluorescent display tube display, or the like can be used, and a transparent EL display is used in this embodiment. An EL display is a known one in which a light emitting layer is sandwiched from both sides by an insulating layer and electrodes, and both outer sides are sandwiched by glass substrates, and the light emitting layer emits light when a voltage is applied between the electrodes. Is.

Since the EL display is self-luminous, it has high brightness and high contrast, and the advertisement display is easily visible even when the vending machine 40 is installed outdoors. Further, since the EL display has high transparency and high transmittance, the front panel 4 of the vending machine 40 is used when no advertisement is displayed, that is, when no light is emitted.
It does not interfere with the product display in 1. Furthermore, by using the transparent display 21, the advertisement and the product 42 can be displayed even when the display 21 emits light to advertise.
And can be seen superimposed.

Since the vending machine 40 is normally operated continuously and unmanned, safety measures are required. As a safety measure, it is conceivable that the temperature of the transparent display 21 does not rise excessively and the adhesive is not peeled off, and that scattering of fragments is prevented when the transparent display 21 is impacted.

In the first embodiment, the transparent display 2
A temperature sensor (not shown) is provided at the position where the temperature is most likely to rise, and the power supply to the transparent display 21 is cut off when the temperature exceeds a predetermined temperature. Alternatively, the vending machine 40 may be provided with a cooling function and the temperature of the transparent display 21 may be managed.

The advertisement display device 20 can notify the advertisement distribution server 10 via the communication network 30 when an abnormality occurs such as when the advertisement display device 20 is overheated. Further, when the stock of the products in the vending machine 40 is low, the advertisement distribution server 10 may be notified of that fact.

On the surface of the transparent display 21,
A transparent protective film (not shown) is attached. Thereby, even if the transparent display 21 is cracked due to stress, it is possible to prevent the fragments of the display 21 from scattering.

Since the vending machine 40 is often installed outdoors and the brightness of the EL display is lower than that of the sunlight, the advertisement display cannot be seen when the sunlight is directly applied to the EL display. Therefore, if an antireflection film is used as the protective film, the reflectance of the transparent display 21 can be reduced to improve the brightness, and the advertisement display can be made easier to see.

By the way, in order to enhance the advertisement display effect of the transparent EL display 21, 1) the brightness of the EL display, 2) the brightness of the product 42, and 3) the brightness of the place where the vending machine 40 is installed. Balance is important.
The brightness of the installation location of the vending machine 40 varies greatly depending on the time of day.

Therefore, in the first embodiment, the brightness of the installation place of the vending machine 40 is detected by the illuminance sensor 23 as described above, and the brightness of the EL display 21 and the product 4 are detected.
The brightness of 2 is adjusted so as to be balanced. Even when the vending machine 40 is installed indoors, it is desirable to perform the same adjustment.

The content of the advertisement information displayed on the transparent display 21 can be set arbitrarily. Cigarettes and beverages are suitable for the product 42 advertised on the transparent display 21, but any product that can be sold by the vending machine 40 can be applied. In particular, regarding cigarettes, in recent years, it has become impossible to carry out advertisements that stimulate purchase intentions due to advertisement regulations in the mass media. Therefore, it is considered very effective to advertise the cigarettes in the vending machine 40 immediately before the purchase to consumers who purchase the cigarettes.

Further, the advertisement content can be changed depending on the installation place of the vending machine 40 and the time zone. The customer base of consumers who purchase products from the vending machine 40 is
It is considered to vary depending on the installation location and time of day. Therefore, an effective advertisement can be performed by changing the content of the advertisement depending on the place where the vending machine 40 is installed and the time zone, and by performing the advertisement adapted to the customer base. For example, advertisements are focused on snacks during the time when students come to purchase snacks, and advertisements are focused on beverages during times when drinks are often purchased.

In such a case, in the advertisement system of the first embodiment, since the plurality of advertisement display devices 20 are connected to the communication network 30, the advertisement contents displayed on each advertisement display device 20 are simultaneously broadcast. Can be changed to For example, when a new product is released, the display contents can be changed all at once by linking with a TV commercial, and the advertising effect can be improved.

Further, in the advertisement system of the first embodiment, the individual advertisement display devices 2 installed in the vending machine 40.
The advertisement content can be changed even from 0. In this case, the advertisement display device 20 makes a change request (update request) for the advertisement information to the advertisement distribution server 10, and the advertisement distribution server 10 transmits the advertisement information to the advertisement display device 20 in response to this request. For example, a vending machine 40
In the store where is installed, it is possible to proactively advertise the product that the user wants to obtain on a predetermined day.

The seller (advertisement provider) who sells the product at the vending machine 40 can place an advertisement about his or her product sold at the vending machine 40 on the transparent display 21 of the vending machine 40. Further, in addition to the advertisement of the product sold by the advertisement provider, the advertisement provider concludes an advertisement contract with the advertisement client who desires the advertisement, and sells the product of the advertisement client to the vending machine 4.
The product can be sold for 0 and the product can be advertised. In this case, the advertisement provider can charge the advertisement requester for the advertisement fee.

FIG. 5 is a conceptual diagram showing an advertising contract between an advertising provider and an advertising client. As shown in FIG. 5, a manufacturing, sales, or rental company of the vending machine 40 equipped with the transparent display 21 rents or sells the vending machine 40 to a company that sells products by the vending machine 40, and the vending machine 40
A company that sells products (advertiser) has an advertising contract with a company that manufactures and sells other similar products (advertiser).

For example, a domestic cigarette maker uses a vending machine 4
It is possible to purchase 0 and sell other companies' cigarettes in the vending machine 40 in addition to their own cigarettes. Vending machine 4
The installation location of 0 may be a retail store that has a sales contract for a product, a convenience store, a supermarket, or a store managed by itself.

The advertisement fee can be changed depending on the time zone for advertising, the number of days, the number of vending machines displaying advertisements, the advertisement area, and the like. For example, the advertisement fee can be set high during the time when many consumers use the vending machine, and the advertisement fee can be set low during the time when there are few consumers. Further, when the advertisement provider creates the advertisement information, the advertisement creation fee can be obtained from the advertisement requester.

Further, the transparent display 21 can display an advertisement of a third party unrelated to the product sold by the vending machine 40. In this case, an advertisement contract is separately signed with a third party who wants an advertisement, and the price for the advertisement is charged. For example, road show information of a movie theater, bargain information of a grocery store, advertisement of other products, and the like can be performed.

Further, the display contents of the transparent display 21 are not limited to advertisements, and information which the consumer may be interested in, such as weather forecast, news, TV programs, etc., may be mixed with the advertisement information and displayed. . As a result, a person passing in front of the vending machine 40 can be interested in the display itself of the vending machine 40, and the advertising effect can be improved.

The advertisement system having the above structure operates as follows. First, as shown in FIG. 1, the advertisement distribution server 10 creates and stores advertisement information. Next, the advertisement distribution server 10
Distributes advertisement information to the advertisement display device 20 via the communication network 30. The advertisement information can be distributed from the advertisement distribution server 10 to the advertisement display device 20 in response to a request from the advertisement display device 20.

In the advertisement display device 20, the advertisement distribution server 1
The advertisement information received from 0 is stored in the memory. Next, the advertisement display device 20 displays an advertisement of the product displayed on the vending machine 40 on the transparent display 21.

As described above, by advertising using the transparent display 21, it is possible to advertise using the front transparent panel 41 of the vending machine 40. Consumers
Products sold at vending machine 40 and transparent display 2
Since the advertisement displayed in 1 can be seen in a superimposed manner,
The product can be directly advertised, and the advertising effect can be enhanced. Consumers can know the characteristics of a new product or a specific product when purchasing the product. As a result, the consumer's willingness to purchase can be increased, and the sales of the advertising product can be improved.

The front transparent panel 4 of the vending machine 40
Since 1 is used to advertise, there is no need to prepare a special place for advertisement. Further, since the display 21 is transparent, if the display is turned off, there is no problem in displaying the product in the vending machine 40.

Further, since the advertisement information is distributed from the external advertisement distribution server 10 connected by the communication network 30, the contents of the advertisement displayed on the plurality of vending machines 40 can be easily changed. Furthermore, the content of the advertisement can be changed depending on the time of day, the advertisement of the new product can be easily performed, and the advertisement can be effectively performed.

Although the advertising contract shown in FIG. 5 is adopted in the first embodiment, the present invention is not limited to this, and other advertising contract forms may be used.

For example, as shown in FIG. 6, a commercial contract is made with a company (advertiser) who manufactures or sells a vending machine 40 having a transparent display 21 or a rental company (advertiser) manufactures or sells products. The vending machine may be installed with a store such as a convenience store or a rental contract, or the vending machine may be installed in a store operated by the company.

Alternatively, as shown in FIG. 7, each store (advertiser) who installs a vending machine equipped with a transparent display 21 sells or rents the vending machine 40 and the owner of the vending machine. Therefore, an advertising contract may be made in which an advertising contract is made with a manufacturer (advertiser) who manufactures and sells products sold by the vending machine.
