When the detector 8 turns into ON state, the drawing out roller 2 is rotated and the bank note 4 is drawn out.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper sheet dispensing device that is built in, for example, an automatic teller machine used in banking.

Among paper sheets such as banknotes, slips, and cards, a feeding device that handles paper sheets such as the above-mentioned example feeds the paper sheets into the feeding section of a case that stores the paper sheets, and is equipped with rollers that are disposed on the tray inside the case. A push stand with a constant spring pressure is applied to the rear side of the paper sheets arranged in a row, and the front side of the paper sheets is urged against a feeding roller to be fed out.

However, as the frequency of use of such dispensing devices has increased in recent years, the storage capacity of paper sheets in the case must be increased. At the same time, the frictional force increases and it becomes impossible to feed out. In this case, it is sufficient to increase the biasing force, but if the amount of paper sheets stored decreases as the paper sheets are fed out, an excessive biasing force will be applied to the paper sheets, inducing two sheets to be fed out. Currently, there is a limit to the storage capacity for paper sheets.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a paper sheet dispensing device that does not cause unfeeding or double dispensing even if the storage capacity of paper sheets is increased.

According to this invention, since a detector is provided to detect the feeding force against the paper sheet when feeding the paper sheet,
The pusher is equipped with a biasing force variable device that can determine whether or not the paper sheet is being fed with the appropriate biasing force, and further adjusts the feeding force based on the detector. By adjusting the urging force of the pusher with the urging force variable device, it is possible to feed out the paper sheets with the optimal feeding urging force as appropriate.

In other words, when the storage capacity of paper sheets is increased, the four forces are increased to eliminate the inability to feed paper sheets, and when the storage capacity of the paper sheet is decreased, the biasing force is weakened according to the degree of decrease to achieve optimal feeding. As a result, the occurrence of two cards etc. becomes completely rare. Therefore, according to this device, it is possible to always maintain an appropriate feeding state for the paper sheets being fed.

An embodiment of the present invention having such characteristics will be described in detail below with reference to the drawings.

...There was a limit. However, as the frequency of use of such dispensing devices increases in recent years, it is desirable to increase the storage capacity of paper sheets in the case. The dispersion of the frictional force on the table top surface, etc. increases at the same time, making it impossible to feed the paper sheet.In other words, as shown in Fig. 5, the frictional resistance and the hooking resistance between the paper sheet and the upper, lower, left and right guide members of the paper sheet increase. It shows the relationship between the resistance value for paper sheets including When the number of stored sheets increases when applying force, the variation B
