2. Description of the Related Art Image forming units such as copiers, printers, facsimile machines, and other image forming devices, printing devices, and the like that continuously form and print images on continuously fed paper The printer has a paper feeding device for continuously feeding paper one by one to the printing unit. The sheet feeding device includes a sheet feeding tray for stacking a sheet bundle, and a sheet feeding mechanism for coming into contact with the uppermost sheet of the sheet bundle in the sheet tray and taking out the sheets one by one to send them out. The paper feed tray is provided with a bottom plate supported in the tray main body so as to be movable up and down, and a bottom plate loaded with a stack of sheets is pushed up by a lifting mechanism so that the upper surface of the sheet bundle is placed on a paper feeding roller that constitutes the sheet feeding mechanism. Press it. By rotating the sheet feeding roller in the sheet feeding direction with the upper surface of the sheet bundle pressed against the sheet feeding roller, the uppermost sheets can be taken out one by one and conveyed to the image forming unit or the like.
Conventionally, in packing and carrying office equipment equipped with such a paper feed tray, in order to prevent rattling of the bottom plate, the bottom plate is fixed in the tray body using an adhesive tape, When peeling the adhesive tape from the bottom plate of the unpacked device, cover the part of the bottom plate with a sheet material and attach the adhesive tape from above the sheet material so that there is no adhesive residue on the bottom plate side. Only both ends are attached to the bottom of the tray body.

[0003]

However, in such a conventional bottom plate fixing method, the bottom plate should be fixed in the tray main body only by fixing the adhesive tape, but In order to eliminate the adhesive residue transferred from the tape, it is necessary to use an extra and dedicated sheet material that has nothing to do with the function of the device at the same time, which has caused the increase in dust. In addition, because the dedicated sheet material that has nothing to do with the function of the equipment is used, it is not necessary to pay attention to the existence of sheet material that is not related to the function of the equipment when unpacking and operating the equipment. As a result, there is a risk that the adhesive tape is forgotten and the device is operated to damage the device. The present invention has been made in view of the above, and is for fixing the bottom plate in the paper feed tray equipped in the paper feed device to the tray body when packing and transporting the device including the paper feed device. ,
The purpose is to attach a sheet material as an enclosed item required for the function of the device to the bottom plate and then fix it with an adhesive tape.

[0004]

In order to solve the above-mentioned problems, the invention of claim 1 is a paper feeding apparatus provided with a paper feeding tray and a paper feeding mechanism, which is supported by a tray body so as to be vertically movable. In the bottom plate pressing structure in which the bottom plate is fixed to the tray body with the adhesive tape via the adhesive-preventing sheet material attached to the bottom plate, as the sheet material, a sheet feeding device,
Alternatively, it is characterized by using a dual-use sheet material that is packed together for use in realizing the function of a device equipped with a paper feeding device. A sheet feeding device having a sheet feeding tray having a vertically movable bottom plate is installed in an image forming apparatus or the like.However, when the image forming apparatus is transported for shipping or the like, the bottom plate is affected by vibration or shock. There is a risk of rattling and causing damage such as breakage or damage. In order to eliminate such inconvenience, the device is provided for transportation with the bottom plate fixed to an appropriate place of the tray body in the immediate vicinity by an adhesive tape. At this time, if the adhesive tape is directly adhered to the bottom plate, the adhesive component (glue) adheres to the bottom plate, and the glue remains even when attempting to peel it off later, which may cause the transfer paper placed on the bottom plate to be torn or dirty. Become. Therefore, a fixing structure has been adopted in which a normal sheet material having no adhesive is previously attached to the surface where the bottom plate and the adhesive tape are in contact with each other, and the adhesive tape is adhered onto the ordinary sheet material and fixed to the tray body side. However, the conventional method requires a dedicated sheet material only for fixing the bottom plate, and this sheet material needs to be discarded after being removed, resulting in an increase in dust. Further, when the device is handed to a user and installed, it is often forgotten to release the fixing of the bottom plate, and if it is operated as it is, the device may not operate normally and may cause a failure. In the present invention, as the sheet material for preventing the adhesive from adhering to the bottom plate, sheet-like equipment (included when packaging the equipment) necessary for operating the equipment is used instead. Therefore, the sheet-like equipment cannot be taken out unless the bottom plate is unfixed at the time of unpacking. Therefore, the possibility of forgetting to release the fixation of the bottom plate is greatly reduced. It should be noted that the term "used to realize the function of a device" means a display sheet that is used by sticking it to a proper place of the device when the device is operated and used. Since it is bundled with, it is also used as a sheet material attached to the bottom plate. A second aspect of the present invention is characterized in that, in the first aspect, the combined sheet material packed together is a size indicating decal. In claim 2, since the enclosed sheet material is the size display decal, there is a work of sticking the display decal at the time of setup, so that the sheet fixed as the packaging material will not be forgotten.
