面には案内レールか設置されている。For example, in commonly used front carding type image recording devices (electrophotographic copying machines), the external shape of the device has been designed to be compact so that it is suitable for transportation, space utilization during installation, and ease of operation of the paper feed cassette. It is configured into a rectangular parallelepiped. Therefore, a photoreceptor drum for forming an image, a toner development process for developing the image on the photoreceptor drum, and an optical system for projecting and exposing the document image onto the photoreceptor drum are arranged in the upper stage, and the image formation It makes up the department. A fixing device for fixing the toner image on the recording paper is also arranged. On the other hand, paper feed stackers with recording paper of various sizes set in the lower stage are installed in several stages according to size, and the configuration is such that the recording paper is fed one by one to the image forming section in the upper stage and images are recorded. There is. The configuration of such an image recording device is called a front loading type, and is described in Japanese Patent Application Laid-Open No. 59-45466,
It is described in JP-A-60-150062 and various publications. In addition, as a U-turn paper feeding method,
It is disclosed in Publication No. 337. Furthermore, Japanese Utility Model Application Publication No. 52-152740 discloses a transfer paper moisture-proofing device comprising a humidity controller, a temperature controller, a heater, an air blower, a control circuit, and a power supply line. On the other hand, the fixing device is designed so that it can be pulled out for cleaning, maintenance, etc. For this reason, a guide rail is installed at the bottom of the lower part of the fixing device.

ある。As described above, in the front loading type image recording apparatus, there is no partition plate between the image forming section installed in the upper stage and the recording stacker means installed in the lower stage, except for the guide rail portion of the fixing device. Therefore, even if the temperature of the entire copying machine changes, the recording paper in the lower paper feed stacker is difficult to dry and the dehumidification effect is poor. As a result, the recording paper at the top of the paper feed stacker and the second recording paper may become loose and not be separated during paper feeding, or the recording paper may curl, causing problems in paper feeding. are doing. Furthermore,
If high-humidity recording paper is fed, the recording paper will be rapidly heated during fusing, causing wrinkles, distorting the image, and making it impossible to obtain clear image recordings (copies). be.

装置である。An object of the present invention is to eliminate these drawbacks and provide a recording device that is always stable. To achieve the above object, the present invention provides an image recording apparatus including a recording paper stacker means for accommodating recording paper to be fed to the image forming section directly below the image forming section. A thermally conductive partition plate is provided to separate the means, and the heating fixing device of the image recording device is closely arranged above the partition plate, and the partition plate is heated by the radiant heat of the fixing device, and further below the heating fixing device. This is a recording paper dehumidifying device for an image recording apparatus, characterized in that the space above the recording paper stacker means is heated and dehumidified.

。Embodiments of the recording paper dehumidifier according to the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes an optical system for projecting and exposing the original onto the photosensitive drum of the image forming section 2. As shown in FIG. Reference numeral 2 denotes an image forming section that includes a photosensitive drum that forms an image projected by the optical system, a toner developing section that develops this image, a cleaning section, and the like. 3 is a paper feed stacker corresponding to various sizes of recording paper P, for example, the upper stage is a paper feed cassette 3A for A4 size, and the lower stage is a paper feed cassette 3A for 84 size.
It is B. By operating the select button, copy start button, etc. on the operation panel of the copying machine, the recording paper P set in the paper feed stackers 3A and 3B of the specified size is fed one by one from the top. The paper is fed and transported by the rollers of the section 4 and sent to the image forming section 2 installed on the upper stage. In the image forming section 2, the photoreceptor drum is rotated and exposed to light to form an image, which is then developed with toner. This toner image is then transferred onto a recording paper P, which is transported to a fixing device 6 by a transport belt 5. In this fixing device 6, the toner image transferred onto the recording paper P is fixed by a heat roller or the like, and then transported to the outside by a paper discharge roller 7. This fixing device 6 is designed so that the entire fixing device 6 can be pulled out for cleaning or maintenance, and for this purpose a guide rail 8 is installed on the bottom surface. Such a front-loading type copying machine has an image forming section 28 and a heat fixing device installed in the upper stage, and a paper feed cassette 3 installed in the lower stage. Further, when the upper image forming section 2 is in operation, the fixing device 6 is also in an operating state and is heated, and in particular, the fixing device 6 radiates heat. This radiant heat mainly radiates upward through the entire space of the image recording apparatus, and has little effect on dehumidifying the recording paper P set in the lower paper feed stacker. Therefore, a partition plate 9 made of a material with good thermal conductivity according to the present invention is installed to completely separate and shield the upper and lower stages. At this time, the structure is such that the heat of the fixing device 6 is transmitted to the partition plate 9 and the partition plate 9 is easily heated. By doing this, the partition plate 9 is heated, and the radiant heat warms the entire lower space where the paper feed stacker 3 is installed, rather than the upper space, by convection. In this way, the recording paper P in the paper feed stacker 3 is dried and dehumidified, and the recording paper P is prevented from being inseparable, curling, wrinkled, etc., and a clear image recording (copy) is always obtained. The partition plate 9 is preferably made of a metal plate such as aluminum that has good thermal conductivity, and if a material and shape with appropriate thickness, quality, and strength are selected, it will have the effect of reinforcing the main body of the copying machine and shielding electrical noise. It is also possible to have

鮮明で安定した画像が記録できるようになった。As described above, in the fixing device of the image recording apparatus of the present invention, the upper image forming section and the lower paper feed cassette are shielded by a partition plate with good thermal conductivity, so that conventional front loading type image recording is not possible. It is now possible to eliminate the effects of humidity on the recording paper set in the paper cassette, which had been a problem with the device. Therefore, there is no inability to separate the recording paper, no curling, no wrinkles during fixing, and clear and stable images can always be recorded.
