Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is provided with an article placement section located lower toward the front end, and a stopper for receiving an article is provided at the front end of the article placement section. A display device for displaying article retrieval information is provided at the front part of the stopper. .

[Conventional technology]

Such a shelf is capable of moving the articles on the article placing section to the front end side by its own weight, and has the advantage of making it easy to take out the articles.Moreover, an indicator indicates that the articles can be taken out easily. It also has the advantage of displaying article removal information such as quantity and allowing appropriate article removal.
Furthermore, in order to accommodate differences in the viewpoints of workers due to differences in height, etc., the display device also has the advantage of being able to adjust the posture of the display device up and down to make it easier for the worker to see.

By the way, conventionally, as shown in FIGS. 10A and 10B, in order to pivot the display H at the front part of the stopper 29 so that it can freely swing up and down, the swing axis at the rear end of the display P was located on the lower end side of the display H.

[Problem that the invention attempts to solve]

According to the above conventional means, when the display H is adjusted to swing downward, a large gap is formed between the upper part of the rear end of the display H and the stopper 29, and the tip of the display H is It will protrude significantly downward. Therefore, due to the existence of the large gap, the item to be taken out enters the gap and is likely to get caught on the rear end of the display H, and the display H that protrudes significantly downward. It may get in the way if something hits the tip (for example, if there is another article placement section below, an object such as an article hits it when taking out an article from that article placement section). Therefore, there was a problem in that workability when taking out articles deteriorated.

The present invention has been developed in view of the above-mentioned circumstances, and its purpose is to make the display device adjustable up and down, making it easy for workers to see, while also making it easier to read when taking out items. The aim is to solve the conventional problem of poor workability.

[Means for solving problems]

The characteristic configuration of the shelf according to the present invention is that the pivot axis on the rear end side of the display is located on the upper end side of the display, and its functions and effects are as follows.

[Effect]

In other words, the upper part of the rear end of the display device, which swings around the swing axis on the rear end side and the upper end side, remains at a substantially constant position regardless of the swinging, and as a result,
A large gap is not formed between the upper part of the rear end of the display and the stopper. Moreover, since the swing axis of the display is located on the rear end side and the upper end side, and is located higher than that of a conventional display, the display swings around the swing axis. teeth,
Compared to the conventional case, the tip portion is prevented from protruding significantly downward.

[Effect of idea]

Therefore, although the posture of the display device is oscillated and adjusted to make it easier for workers to see, it is possible to avoid objects from getting caught on the rear end of the display device, and to prevent the downward movement of the display device. This prevents objects from hitting the tip of the protruding display (for example, if there is another article placement section below, objects such as articles will hit it when taking out an article from that article placement section). As a result, the work of taking out items can now be carried out smoothly.
