Description

The present invention relates to a paper sheet conveying device and a paper sheet handling device.

In recent years, for example, in order to strengthen security, paper handling devices, which are automatic teller machine (ATM) banknote deposit and withdrawal machines, have become more and more secure. Increasingly, there are structures in which the cassette section is separated from the cassette section. Specifically, the bill depositing and dispensing machine is divided into an upper unit and a lower unit. The upper unit has functions for counting bills input by the end user, primary storage, and bill counting during withdrawal, and the lower unit stores bills. It consists of a cassette. The lower unit is installed in a safe surrounded by a thick metal plate and has a high level of security that only a limited number of people can access, while the upper unit is classified as a low level of security. As described above, in recent years, bill depositing and dispensing machines have become mainstream to have a structure that increases security by separating the people who can use the machine at the top and bottom.

In a structure divided into such an upper unit and a lower unit, a device for conveying paper sheets such as banknotes between the upper unit and the lower unit is conventionally disclosed in, for example, Patent Document 1. In the invention of Patent Document 1, a passage member that forms a passage is provided in a partition between an upper unit and a lower unit. The passage member protrudes to the upper side and the lower side with the partition wall in between, and has an upper end portion and a lower end portion formed in a comb-like shape in which convex portions and concave portions are alternately arranged. The comb teeth at the upper end of the passage member mesh with the comb teeth of a pair of guides forming a connection path of the upper unit. The comb teeth at the lower end of the passage member engage with the grooves at the banknote entrance of the storage cassette of the lower unit. Therefore, in the invention of Patent Document 1, the passage in the partition wall continues seamlessly so as to partially overlap the connection path in the upper unit and the banknote inlet in the lower unit.
