Abstract

PURPOSE:To prevent a shape change due to humidity in atmospheric air or other factors and damage and fouling in the end section of recording paper directly exposed and left to stand in atmospheric air from a recording-paper lot by covering a space, in which the recording-paper lot is housed, in a box shape and driving and controlling a dehumidifying means provided outside. CONSTITUTION:A box-shaped space is formed by a recording-paper lot inserting mouth 102 at one end and a recording-paper extracting mouth 103 at the other end in a recording paper stocker 101, and a humidity sensor 104 is installed inside. The recording-paper lot inserting mouth 102 is opened to the upper section of the recording paper stocker 101, and a recording paper lot 204 is inserted and mounted. The recording-paper lot inserting mouth 102 keep closed at the normal time except said time. When humidity in atmospheric air is elevated and humidity in the recording paper stocker 101 is also increased, the humidity sensor 104 detects the increase of humidity. The inside of the recording paper stocker 101 is dehumidified before getting subject to a shaped change due to the absorption of humidity in the end of recording paper. Accordingly, dehumidification operation is conducted only at the time required, and a dehumidifying means can be scaled down.

Conventional technology One feature of an image recording device that consists of winding recording paper around a drum and scanning by rotating the drum and scanning by parallel movement of a recording pad placed opposite the drum is that it can provide a wide drawing area. For example, in the case of an on-demand inkjet recording system, if there is no restriction on the drum size or the overall size of the apparatus, it is possible to record images of any size. However, in recent years, image recording using fully multi-layered printers, such as those using heat-sublimation thermal heads, is currently limited to the size of A5 to A4 size paper due to limitations from head length and ink sheet. It is difficult to obtain a larger drawing area. Therefore, an image recording apparatus that can record a wide drawing area, for example, an AI plate or 81 plate size in one scan, has a great feature.

FIG. 2(a) shows the external appearance of the image recording apparatus. When the drum cover 211 is opened, the drum 20 shown in FIG. 2(b) is set. Recording paper lots 204 packed in bags for each lot are placed on the recording paper mounting table 210, and only one end of the bag is opened in order to take out the recording papers 202 one by one from the recording paper loft 204. The reason why the recording paper is placed in a bag on the recording paper mounting table is to protect the recording paper.
For example, paper for inkjet recording usually has a special coating on its surface in consideration of ink absorption, etc., and the price is high if it is large, so such installation is done to protect the recording paper. There is. Winding around the drum 201 is as follows:
A groove 203 is formed in a part of the drum 201, the paper end 202a pulled out from the recording paper loft 204 is correctly inserted into the groove 203, and the adhesive tape 208 is used to attach the paper to the drum 201.
When the drum 201 is rotated in this state, the recording paper 202 is drawn out from the recording paper lot 204 while being in close contact with the drum 201. Then, by adhesively fixing the other end 202b with adhesive tape 208, the drum 20
The paper winding to 1 is completed.

Problems to be Solved by the Invention However, in the image recording apparatus having the above configuration, if the paper end 202a is not inserted parallel to the drum 201 over its entire width, the entire recording paper 202 will not be brought into close contact with the drum properly, and some of the paper will be damaged. This may cause problems as it may float or be installed at an angle with respect to the skin drawing area. Therefore, insertion of the paper end 202a into the groove 203 is extremely important.

On the other hand, as the groove 203 itself becomes wider, the drum itself inevitably becomes larger. However, it is also necessary to reduce the weight of the entire device as much as possible, so a configuration is adopted in which the wall thickness of the drum 201 is made as thin as possible. As a result, the area that can be grooved becomes narrower, so it is not possible to make a very large groove 203.
At present, the limits are a gap of about 2 to 3 m and a depth of about 3 to 5 m. Therefore, the shape of the paper edge 202a is required to be as smooth as possible across the width of the paper. However, as described above, only a portion of the recording paper lot 204 is unsealed and only that portion is directly exposed to the atmosphere. Therefore, the unsealed portion of the recording paper 202 is particularly prone to absorb moisture when the relative humidity is high, for example. As a result, the smoothness is impaired, and the influence of high humidity immediately appears as a wavy change in shape of the paper edge 202a of 2-3 or more. This paper end 202 a
The wavy shape change makes it extremely difficult to insert the paper end 202a into the groove 203 on the drum 201. Especially B
If the recording paper is larger than the size of one version, it will be as wide as 728 mm or more on the short side, so it will be almost impossible to correctly insert it into the groove 203 described above.

The present invention has been made in view of the above problems, and includes an image recording apparatus that winds paper around a drum.
The end portion 202a of the recording paper is left exposed directly to the atmosphere.
The purpose is to protect the material from changes in shape due to atmospheric humidity or other factors, as well as damage and dirt between the parts.

When the humidity in the atmosphere increases and the humidity inside the recording paper stocker 101 also increases, the humidity sensor 104 detects this. The inside of the recording paper stocker 101 is dehumidified before the end of the recording paper reaches a state where its shape changes due to humidity absorption. This is carried out by operating the humidity sensor 104, which is set according to conditions determined in advance in relation to the humidity absorption characteristics of the recording paper, and driving and controlling the air conditioner adjuster 120. The air conditioner digital recorder 120 is the recording paper stocker 10.
1 through an absorption pipe 121 and a suction pipe 122. Recording paper stocker 10 sucked from suction pipe 121
The air in the recording paper stocker 101 is guided to a near conditioner 120, dehumidified, and then returned to the recording paper stocker 101 via a suction pipe 122. As a result, it is possible to maintain a dehumidified atmosphere in the recording paper stocker 101, and it is possible to keep the particularly important edges of the recording paper smooth.

Furthermore, the effect becomes more pronounced as the recording paper size becomes larger. In addition, other effects include making only the paper stocker part box-shaped, minimizing the space for dehumidification management, and using a humidity sensor to control the dehumidification and dehumidifying only when necessary, making the dehumidification means more compact. It is also possible to achieve a configuration with good performance. In addition, by fixing one lid of the recording paper stocker to a part of the drum cover and opening and closing the drum cover and opening and closing of the recording paper stocker, it is possible to realize that the recording paper stocker is a sealed box-shaped space. To realize smooth paper removal from the storfka without any unnecessary work.
