BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper feed tray for accommodating paper such as photographic paper or copy paper formed in a predetermined size, and a video image on the photographic paper taken out from the paper feed tray. The present invention relates to a paper feeding device used in a printer that leaves a recorded image of a hard copy in color printing or the like, or a copying machine that copies the written content of an original document to a copy sheet that is also taken out.

[0002]

2. Description of the Related Art Generally, a paper feeding tray of this type and a paper feeding device using the paper feeding tray are said to be for domestic use and commercial use such as a home video printer and a commercial copying machine. Regardless of, it is used in various electronic devices.

Conventionally, the paper feed tray used in this type of paper feeding apparatus is composed of only a box type tray main body for accommodating a large number of printing papers or copy papers in a stacked state. The loading port for replenishment was largely open. When photographic paper or the like is fed to a printer or the like using this paper feed tray, if the photographic paper or the like is fed in a laterally displaced state, printing or the like is performed in such a displaced state, or
If the paper is supplied in an obliquely inclined state, printing or the like is performed in such an inclined state, and in any case, a problem of defective printing occurs.

As a method for preventing the occurrence of such a problem and preventing the photographic paper or the like from being rampant and supplying a stable supply, for example, the following two methods can be considered. The first is a method in which the width of a paper storage unit that stores paper such as photographic paper matches the width of the photographic paper and the like so that no gap is created between the photographic paper and the paper feed tray. In addition, the second is that while pressing the printing paper or the like with a spring from a direction orthogonal to the paper feeding direction to apply a lateral pressure to the printing paper or the like, while pressing one side of the printing paper or the like against one side wall surface of the paper feed tray. It is a method of conveying in the paper feeding direction.

[0005]

However, in the paper feeding method using the conventional paper feeding tray as described above, in the first method, the size of the printing paper or the like is formed larger than the size of the paper accommodating portion. However, if the size of the printing paper is smaller than the size of the paper storage unit, the printing paper will move laterally in the paper storage unit. Or, the posture may be changed obliquely, so that the paper cannot be fed in a normal state and a paper feeding failure occurs. Further, although it is possible to load and feed photographic paper of a specific size or the like that matches the paper feed tray, there is the problem that it cannot be used for photographic paper of a different size.

In the second method described above, when the lateral pressure is applied to the photographic printing paper or the like too much, the photographic printing paper or the like is detached from the tray by the force applied from the lateral direction during the paper feeding and is obliquely supplied to form the diagonal printing. There is a problem that the photographic paper or the like is deformed to form wrinkles, and the wrinkles are printed on the wrinkles.

The present invention has been made in view of the above conventional problems, and by pressing the paper contained in a paper feed tray with a lid from above, the paper comes off the paper feed tray or is deformed. It is an object of the present invention to provide a paper feed tray capable of preventing the paper feed and a paper feeding device using the paper feed tray.
