DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device including a display section that displays characters using a non-directional light emitting body.

[Conventional technology]

Such a display device can be used for various purposes, such as being placed corresponding to each article storage position of a shelf that stores multiple types of articles in different categories, and used to display the amount of articles to be taken out. will be used.

By the way, for example, when displaying the amount taken out of each of multiple types of articles stored on a shelf, it is difficult to determine which display device among the many installed display devices is displaying the amount taken out. It is also necessary to instruct the operator as to which of the following items is to be removed.

For this reason, in the past, a lamp was provided in a protruding state separately from the display device, and the article to be removed was displayed by lighting the lamp. That is, conventionally, a specularly transparent cover body is generally provided on the front side of the display section in a position parallel or substantially parallel to the display section. Therefore, if you check the display operation of the display section through the cover body, you can of course confirm that the item requires removal work, but the range in which you can confirm the display operation of the display section through the cover body is limited to Since the area is small enough to be viewed from the front side, it was necessary to provide another lamp in order to be able to check the display operation of the display unit from the sides of the display unit.

[Problem to be solved by the invention]

If a separate lamp is provided to ensure the display operation of the display unit, the lamp will make the entire device complicated and expensive, so improvements are being sought.

By the way, if a large number of display devices are installed on a shelf to display the amount taken out for a large number of items, a large number of lamps will be provided corresponding to each of the large number of display devices. The overall structure was quite complex and expensive due to the lamp.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to make it possible to confirm from the side that the display section is operating without providing a special lamp. It is in.

[Means to solve the problem]

In the display device according to the present invention, a diffusely transparent fixed wall is provided on the outer periphery of the front side of a display section that displays characters using non-directional light emitters.

Further, a force/<integrity is provided to cover the front side of the display section,
A part of the cover body is the fixed wall, and another part of the cover body is formed of a specularly transparent object.

[For production]

The effects of the above feature configuration are as follows.

In other words, the light emitted from the display section is irradiated to the sides of the display section due to the diffusion effect of the fixed wall, so it can be confirmed from the side that the display section is operating. .

In addition, when providing a convex force/NJ unit that covers the front side of the display section, a part of the cover body is made into a diffusely permeable fixed wall, and at least the part of the cover body facing the front side of the display section is It is made of a specularly transparent material, and the display operation of the display unit can be confirmed from the side while suppressing the adhesion of foreign matter with the cover body.

〔Effect of the invention〕

In other words, by simply modifying the device by installing a fixed wall that is diffusely permeable, it is now possible to confirm that the display is operating from the side. Compared to the conventional structure in which special lamps are provided, the structure for display can be simplified.

The container position determining means (102) manages the container position based on the information from the transport distance detecting means (100). To explain further, the conveyance distance detection means (100) detects, as described above, each time the container (Z) moves a distance corresponding to the spacing between the shelf portions (IA).
Since the measured time is cleared, the container position determination means (102) uses the destination information of the container (Z) supplied to the starting end of the transport conveyor (2) and the location where the container (2) is transported. The container position is determined by associating and managing the number of times the measurement time is cleared as the measurement time progresses.

Therefore, the display device (H) is connected to the work controller (7).
), the main and auxiliary indicator lights (1
1) and (12) are operated based on information from a controller provided in the display (H).

In other words, the work controller (7) manages the position of the containers (2) that are sequentially transported relative to each shelf section (IA), and displays the next supply to the indicator (H) of each shelf section (IA). The work data of each container (Z) is sent to the controller of the display (H), and as the next container (H) is supplied to the front side of each shelf section (IA), each display ( H) to display the next work data. and,
The main indicator light (11) is OR-connected to all the indicators (H) provided on the shelf (IA), and each indicator (1
