BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet processing apparatus, and in particular, receives paper sheets from an upper portion of a storage section and stores them in a stacked state, and sequentially stores one sheet of paper sheets from a lower portion of the storage section. The present invention relates to a paper sheet storing and feeding device that feeds each sheet.

[0002]

2. Description of the Related Art As described above, paper sheets are received from the upper part of the storage part and stored in a stacked state, and the sheets are sequentially fed out one by one from the lower part of the storage part. For example, there is an apparatus described in Japanese Patent Application Laid-Open No. 2-166593.

The above publication discloses two different examples of the above-mentioned apparatus. One of them is that a temporary storage room is provided in an upper area in a storage section or in an upper position separately from the storage section. An openable / closable temporary holding plate is provided at the bottom of the temporary holding room. The temporary holding room is formed with a paper sheet inlet for feeding sheets one by one. Sheets fed one by one are temporarily stored in a stacked state on a temporary storage plate. Below the temporary holding plate, there is provided a receiving plate which can move up and down and can be opened and closed, and which is retracted outside the storage portion when opened, and this receiving plate is closed when receiving paper sheets, and the receiving plate is closed. When opened, the temporarily stored paper sheets in the stacked state are placed on the receiving plate. Then, the receiving plate is configured such that the upper surface of the stacked stacked sheets descends to a level lower than the temporary holding plate and stops, so that the temporarily stored sheets are placed on the receiving plate. The receiving plate is lowered each time it is placed. Further, when the receiving plate is lowered to a predetermined level, the stacking sheets which have been opened and are dropped thereon fall by their own weight, and the stacking sheets placed on the feeding means (feeding roller, central area roller). The paper is stacked on the stored paper sheets in a state, is united with the stored paper sheets, and is fed one by one by a feeding means. Another example is that the above-mentioned example does not have a temporary holding room, and the sheets fed one by one from the sheet feeding inlet of the storage unit are stacked on the receiving plate described above. It was done in. The receiving plate in this example is also lowered each time a sheet is fed, and is opened when the receiving plate is lowered to a predetermined level. Thereafter, the receiving device is completely the same as the above-described example.

[0004]

However, both of the above two examples require a receiving plate that moves up and down in the storage section, and it is necessary to move the receiving plate up and down and open and close it. The receiving plate retracts out of the storage section when it is opened, rises in the retracted state, closes when it reaches a predetermined height, and enters the storage section. It is necessary to secure a space that allows the board to move, and there are various problems such as an increase in the size of the apparatus. If the stacking temporary sheets on the temporary holding plate are dropped on the storage sheets on the feeding means by their own weight, when the amount of the storage sheets is small, the drop is large and the stacking collapses. It is easy to occur, and when this stacking collapse occurs, it causes a feeding failure. Further, if the sheets fed one by one from the sheet feeding inlet at the upper part of the storage unit without the receiving plate are directly fed to the upper surface of the storage sheets and stored in a stacked state, If the drop is large as described above, the sent paper sheets will stand up or break and ride on the upper surface of the stored paper sheets, and in this case, poor stacking will occur as in the case described above, which will hinder feeding. There is a problem that will cause.

In view of this, the present invention has been made in consideration of the paper sheets to be received (ie, temporarily stacked paper sheets in a stacked state or paper sheets which are fed one by one from a paper sheet feeding inlet, on a paper sheet mounting bottom plate or on the same. Paper sheets sent to the top of the stacked paper sheets above)
Paper stacking and feeding device which can receive and store stacks in a stack without disturbing the stacking state of paper sheets in the storage section, without complicating the apparatus configuration and increasing the size. It was done for the purpose of doing.

[0006]

As described above, according to the present invention, the paper sheet placing bottom plate in the storage section is formed so as to be able to move up and down, and when the paper sheets are received, it is raised to the receiving position and the paper sheets are placed on the upper surface. Is stacked in the stacking state, and when the sheets are fed, the sheet is lowered to the feeding position so as to function as the bottom plate of the storage unit at the time of feeding, so that the stacking state of the stacked sheets when storing the sheets. And does not hinder the delivery. In the case of the receiving plate used in the past, it was necessary to provide the receiving plate so as to be vertically movable and openable and closable, and to secure a space for moving the receiving plate outside the storage portion. When moving the paper sheet loading bottom plate, which is the bottom plate of the storage section, up and down, it is not necessary to open and close this bottom plate, just raise and lower in the storage section, so a large space is secured outside the storage section No need to do. Further, since the opening / closing operation is not required only by elevating and lowering, the structure of the apparatus can be simplified. Also, a paper sheet return lever having a paper sheet return portion is provided, and the central area roller is made reversible, so that when the paper sheet mounting bottom plate is raised from the feeding position to the receiving position, at the time of the start of lifting or immediately before the start of lifting. The central area roller is temporarily reversed, and the paper sheet return portion of the paper sheet return lever is swung upward to pull out the leading end of the paper sheet entering the gate section from the gate section. Since the mounting bottom plate is raised, the leading edge of the paper sheet to be fed out is raised together with the paper sheet mounting bottom plate without being damaged,
Some of the paper sheets left inside the gate, or the stacking state of the paper sheets may be disturbed or collapsed due to the rise of the paper sheet mounting bottom plate with the remaining paper sheets Then, when the paper sheet placement bottom plate is lowered again and is located at the feeding position, the paper sheets to be fed out on the paper sheet placement bottom plate are fed into the gate portion for the first time by the subsequent feeding operation. Therefore, there is an effect that the feeding operation is performed smoothly and no feeding defect occurs.
