The video information stored in the 0 storage area can be read. Then, by moving the pickup 22 to a predetermined position, a cueing state in which the video information of the DVD 10 can be read from the beginning is formed.

This DVD drive unit 5
The operation is controlled by the control unit 8. That is, the operation state of the drive mechanism and the position of the pickup 22 are controlled by the control unit 8. The video information read by the pickup 22 is input to the control unit 8.

The image display unit 3 functions as an image display device of the present invention.
It has an image display unit composed of an FT liquid crystal or the like. The operation of the image display unit 3 is also controlled by the control unit 8. That is, the control unit 8 expands the video information read by the pickup 22 to generate image data for display, and causes the generated image data (that is, the advertisement video) to be displayed on the video display unit. The image display unit of the image display unit 3 may use another image display device such as a plasma display. And, as in the present embodiment, the image display unit 3 can be made thin by forming the image display unit with a liquid crystal device,
This contributes to a reduction in the thickness of the display device 1.

The sensor unit 6 functions as a purchaser detecting means of the present invention. The sensor unit 6 is for detecting a purchaser who is in the vicinity of a selling fixture, which will be described later, and includes a detection unit 6a constituted by, for example, an infrared sensor. The detection signal from the detection unit 6a is output to the control unit 8, and the control unit 8 determines whether or not there is a purchaser near the sales furniture based on the detection signal. Note that the detection unit 6a of the sensor unit 6 is not limited to the infrared sensor as long as it can detect a purchaser near the selling furniture. For example, a surface temperature sensor that can measure the surface temperature of an object in a non-contact manner may be used. Further, the sensor unit 6 may be configured separately from the casing 2 so that the sensor unit 6 and the control unit 8 are electrically connected. For example, the sensor unit 6 may be constituted by a floor mat provided with a pressure-sensitive sensor as the detection unit 6a on a floor mat laid on the floor of a store.

The speaker 7 outputs audio based on audio information included in the video information. That is, the control unit 8 extracts audio information from the video information read by the pickup 22, amplifies the audio information as appropriate, and supplies the amplified audio information to the speaker 7.

Next, the manner in which the above-described display device 1 is attached to the furniture for sale will be described.

FIG. 3 is a diagram illustrating a state in which the display device 1 is attached to a product display shelf (a kind of furniture) 31 in a store. In this example, the display device 1 is attached using a support shaft 33 having a clamp portion 32 attached to one end portion and a rotary joint 34 attached to the other end portion. That is, the rotation joint 3 of the support shaft 33
4 is joined to the arm member 12, the clamp portion 32 is fitted to the upper end portion of the back plate 35 of the product display shelf 31 from above, and the back plate 35 is sandwiched by the clamp portion 32 from the front-rear direction. Is fixed to the product display shelf 31.

In this fixed state, the display device 1 is rotatable up and down about the mounting position of the support members 13 and 13 and is horizontally rotatable about the rotary joint 34. Therefore, by adjusting the tilting state of the display device 1, the image display unit of the image display unit 3 can be made easily viewable by the purchaser.

In this configuration, since the back plate 35 of the product display shelf 31 is merely sandwiched and fixed by the clamp portion 32, the mounting operation is easy. Further, since the depth of the display device 1 and the arm member 12 in the front-rear direction is short, the display device 1 and the arm member 12 can be installed even in a slight space above the back plate 35. Further, since the display device 1 is operated by the power supply unit 9 constituted by a storage battery, there is no need to provide a power supply line for connecting to an outlet, and the display device 1 can be arranged relatively freely. In addition, since the display device 1 is arranged above the back plate 35, it is possible to display products on the lower side of the display device 1.
For this reason, the display apparatus 1 can be installed without reducing the amount of displayed products from the past.

Therefore, it is not only possible to install the display device 1 suitably in a store having a relatively large sales area such as a department store or a supermarket, but also in the convenience store where the installation of the display device 1 has conventionally been difficult due to the small sales area. It can be suitably installed even in a small store such as a store. By displaying a product to be explained on the lower side of the display device 1, the display device 1 and the product can be brought closer to each other, and the product can be surely appealed to the purchaser. Differentiation from other commodities arranged together on the display shelf 31 can also be achieved.

FIG. 4 shows an example in which the display device 1 is supported by the casing 2 and the arm member 12 by rotating the arm member 12 rearward of the casing 2. In this example, since no special fixing member is required, the configuration is simple. In addition, since the display device 1 can be freely placed on the shelf (see FIG. 3) of the product display shelf 31, it is easy to change the installation location of the display device 1.

FIG. 5 shows an example in which the display device 1 is attached to a so-called net screen member in which a net portion 42 in which a plurality of wire members 41 are assembled in the vertical and horizontal directions is attached to a rectangular frame. This net screen member is also a kind of sales furniture.
A hook (not shown) is attached to the hook, and a stationery such as a writing instrument or a tool such as a nail or an adhesive tape is hooked on the hook, and the stationery or the tool is displayed as a product. In this configuration, a mounting member 43 joined to the arm member 12 and a holding plate 44 paired with the mounting member 43 are provided.
Then, the display device 1 is fixed to the net portion 42 by sandwiching the net portion 42 from the front-back direction and tightening the attachment member 43 and the holding plate 44 with screws 45 or the like.

FIG. 6 shows an example in which the tip of a fixing bolt 51 is embedded in a concrete pillar or wall, and the display device 1 is mounted on a pillar or wall of a store with the fixing bolt 51. This example is useful when, for example, the display device 1 is attached so as to correspond to a refrigerated display (a type of sales furniture) in a store. That is, in this refrigerated display cabinet, it is difficult to install the display device 1 in the refrigerator due to a temperature problem, and it is also difficult to directly attach the display device 1 to a glass door portion due to dew condensation. Then, by attaching the display device 1 to a pillar, a wall, or the like of a store, the display device 1 is located immediately near the refrigerated display cabinet.
Can be arranged. As a result, the advertisement video of the refrigerated product can be broadcast immediately near the refrigerated display cabinet.

In addition, the display device 1 is also used in vending machines (a kind of vending equipment) installed indoors and outdoors, for example, vending machines for selling juices and cigarettes. Can be installed.

Next, the operation of the display device 1 described above,
That is, the control by the control unit 8 will be described with reference to the flowchart of FIG. In the display device 1, when the power is turned on, first, an initialization process (S1) is performed. In this initialization process, the area of the RAM is cleared, the pickup 22 is moved to a predetermined position, and the unit video information stored in the first unit information storage area 21A of the DVD 10 can be read from the beginning. I do.

After performing the initialization process (S1), it is determined whether or not a purchaser has arrived near the selling furniture (S1).
2). This determination is made based on a purchaser detection signal (purchaser detection information) from the sensor unit 6. For example,
A buyer is detected, and the detection status is maintained for a certain period of time (for example,
If it continues for one second), it is determined that the purchaser has arrived, and the process shifts to the first unit video broadcasting process (S3). On the other hand, if the buyer is not determined to have arrived,
The purchaser detection process of S2 is repeatedly executed.

Here, on condition that the purchaser has been detected for a certain period of time, the first unit video broadcasting process (S
The reason for shifting to 3) is to simply exclude passers-by. That is, it is considered that a buyer who is staying near the selling furniture is likely to be somewhat interested in the product, and by broadcasting an advertisement image of the product to such a buyer, It can increase purchase motivation.

In the first unit image broadcasting process (S3), the advertisement image of the product is displayed on the image display unit 3 sequentially from the beginning. In the present embodiment, the unit video information stored in the first unit information storage area 21A of the DVD 10, that is, the advertisement video explaining the outline of the product is displayed on the video display unit of the image display unit 3. Then, as described above, since the broadcast processing in S3 is started on condition that the buyer comes near the selling furniture, the attention of the buyer can be obtained, and a high appealing effect can be obtained. it can.

When the broadcasting of the first unit video is started, the control unit 8 (display control means) executes the second unit video broadcasting process (S
5) Buyer detection processing for determining whether or not a purchaser is present in the vicinity of the sales furniture to determine whether or not to perform (5)
I do. This purchaser confirmation processing is also performed by the sensor unit 6.
For example, when the detection state of the purchaser continues for a certain period of time (about one second), it is determined that there is a purchaser.

The purchaser detection process in S4 can be performed at any time after the execution of the first unit video broadcasting process (S3) and before the execution of the second unit video broadcasting process (S5). It is preferable that the processing be started a predetermined time before the end of the first unit video broadcasting process and be completed at the end of this process. This is for the following reason. That is, it is considered that the buyer whose existence has been confirmed at the end of the broadcast of the advertising video of the outline description is highly likely to be interested in the product. Then, when the presence of the purchaser is confirmed at the end of the broadcast of the advertisement video, the second unit video broadcast processing of S5 is performed to broadcast a more detailed advertisement video. By ending the detection processing in S4 at the end of the broadcast, a detailed advertisement video can be broadcast immediately after the video of the outline description. As a result, interested buyers can be attracted.

When the presence of the purchaser is confirmed in the purchaser detection processing, the process proceeds to the second unit video broadcasting processing (S5) as described above, while the existence of the purchaser cannot be confirmed. If so, the cueing process of S6 is executed.
In the cueing process (S6), the DVD drive unit 5 is controlled so that the video information stored in the first unit information storage area 21A of the DVD 10 can be read from the beginning.
When the cueing process is completed, the process proceeds to S2,
Execute buyer detection processing.

In the second unit video broadcasting process (S5), an advertisement video based on the unit video information stored in the second unit information storage area 21B is broadcast. That is, an advertisement video that describes a product in more detail than the advertisement video of the first unit video broadcast process (S3) is broadcast.

When the second unit video broadcasting process is started,
At an arbitrary timing, a purchaser confirmation process (S7) for determining whether or not there is a purchaser near the selling furniture is performed. This purchaser confirmation processing is also performed based on the purchaser detection signal from the sensor unit 6 in the same manner as the processing in S4. Here, when the presence of the purchaser is confirmed, the process proceeds to the third unit video broadcasting process (S8) after the completion of the second unit video broadcasting process, and the unit stored in the third unit information storage area 21C. Broadcasts advertising videos based on video information. That is, the advertisement video explaining the product in more detail than the advertisement video of the second unit video broadcasting process (S5) is continuously broadcast. On the other hand, if the presence of the purchaser cannot be confirmed, the cueing process of S6 is executed, and the DVD drive unit 5 is controlled so that the video information stored in the first unit information storage area 21A can be read from the beginning. I do. Then, when the third unit video broadcasting process (S8) ends and the broadcasting of the advertisement video of the detailed product description ends, the cueing process of S6 is executed, and the process shifts to the purchaser detection process of S2.

As described above, in the display device 1 of the present embodiment, the control unit 8 (control means) receives the purchaser near the furniture for sale based on the purchaser detection information from the sensor unit 6 as the purchaser detection means. It is determined whether or not (S
2). If it is determined that the purchaser has arrived, the advertisement video of the product is displayed from the beginning (S3). Further, the control unit 8 (display control means) continuously displays, after the previous advertisement video displayed based on the unit video information, the advertisement video after the product description is more detailed than the advertisement video, Here, the control unit 8 (control means) determines whether or not there is a buyer near the furniture for sale before starting the display of the advertising image thereafter (S4, S7). In addition, the advertisement video for explaining the product in more detail than the broadcasted advertisement video is continuously displayed (S5, S8). on the other hand,
If it cannot be determined that there is a purchaser, or if the advertisement video has been broadcast to the end, the control unit 8 (cueing means) performs a cueing process (S6) to start the advertisement video of the product. A displayable state is formed from.

In the above description of the operation, the control section 8 (the cueing means) can read the video information stored in the first unit information storage area 21A of the DVD 10 from the beginning in the cueing processing in S6. Although the DVD drive unit 5 is controlled to the state, the present invention is not limited to this configuration, and the position of the cue can be set arbitrarily.

For example, the unit information storage areas 21A, 21
B, 21C, the video information of each product constituting the series product is stored corresponding to each of the first unit information storage area 21A, the second unit information storage area 21B, the third unit information storage area 21C, the first unit In the display device 1 configured to sequentially display the advertisement video in the order of the information storage areas 21A, if it is determined that the advertisement video in the third unit information storage area 21C is not to be displayed, the second cueing process is performed. The DVD drive unit 5 may be controlled so that the advertisement video in the unit information storage area 21B can be displayed from the beginning. In the case where a plurality of information storage areas 21 are provided on the DVD 10 and video information on a plurality of types of commodities constituting a series product is stored in each information storage area 21, each information storage area 21 What is necessary is just to control a video display.

The advertisement video storage medium for storing the video information may be any storage medium that can store the video information and can perform the cueing at a high speed.
A memory may be used. And, when the DVD 10 is used, it is possible to provide a video of high image quality and sound quality to the purchaser,
In addition, there is an advantage that the image is not degraded even if it is repeatedly reproduced.

As described above, the present invention has the following effects. According to the invention described in claim 1, the control means determines that the purchaser has arrived near the sales furniture based on the purchaser detection information from the purchaser detection means, and on the condition that the purchaser has arrived. Since the advertisement image of the product is displayed from the beginning, it is possible to attract the purchaser and obtain a high appeal effect. Also, since the video information reading means is controlled by the cueing means so that the video information of the advertisement video storage medium can be read from the beginning, the clerk or the like can perform a troublesome operation such as rewinding the video tape without performing a troublesome operation. The work load can be reduced.

According to the second aspect of the present invention, since the advertisement video storage medium is constituted by an exchangeable digital video disk, the display device can be made compact, and the area of a store such as a convenience store is small. Even in a store where it is difficult to secure an installation space for an advertisement display device, it can be easily installed. Also, the advertising content can be changed only by replacing the digital video disc. Furthermore, with this digital video disc, there is no deterioration in image quality even if it is repeatedly played back, so that high-quality and high-quality sound images can be provided to purchasers over a long period of time, and high appealing power is exerted over a long period of time.
