JPH04232589A - Paper money recognizing device - Google Patents

Abstract

PURPOSE:To easily change the denomination of paper money desired to be recognized. CONSTITUTION:Optical information and magnetic information are read from paper money 2 carried on a paper money carrying path 1 by an optical sensor 3 and a magnetic sensor 4. These information are compared with basic data for recognition stored in a RAM card 7, which is freely attached to and detached from a device, by a comparing operation circuit 6.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a banknote recognition device, and more particularly to a method for storing basic recognition data used in banknote recognition in a banknote recognition device.

0002

2. Description of the Related Art Conventionally, in a banknote recognition device, basic recognition data used for banknote recognition is stored in a ROM (read only memory), and this ROM is mounted on a board. Therefore, basic data for recognition can only be stored in the capacity of the ROM, and the types of banknotes that can be recognized are limited. Furthermore, in order to change the type of banknotes to be recognized, the ROM had to be converted, that is, the board had to be replaced.

[0003] In such a conventional banknote recognition device, the RO
The basic data for recognition is stored in the limited capacity of M, so if you want to change the type of banknote you want to recognize,
Since the ROM is directly soldered to the board, there is a problem in that the board itself must be replaced.

OBJECTS OF THE INVENTION The present invention has been made to eliminate the problems of the conventional devices as described above, and an object of the present invention is to provide a bill recognition device that can easily change the type of bill to be recognized.

[0005]

[Structure of the Invention] A banknote recognition device according to the present invention is a banknote recognition device that recognizes a conveyed banknote based on recognition data stored in advance, and includes a detachable banknote recognition device in which the recognition data is stored. It is characterized by having a memory card.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, a banknote transport path 1 transports banknotes 2 in the direction of arrow A. At this time, when the banknote 2 conveyed on the banknote transport path 1 passes the detection position, the optical sensor 3 reads the optical information of the banknote 2 and sends it to the A/D (analog/digital) conversion circuit 5. Moreover, when the banknote 2 conveyed on the banknote conveyance path 1 passes the detection position, the magnetic sensor 4 reads the magnetic information of the banknote 2 and sends it to the A/D conversion circuit 5.
Send to.

The A/D conversion circuit 5 A/D converts the optical information of the banknote 2 from the optical sensor 3 and the magnetic information of the banknote 2 from the magnetic sensor 4, respectively, and compares and calculates the converted digital signals. The signal is sent to circuit 6.

The comparison calculation circuit 6 compares the digital signal from the A/D conversion circuit 5 with basic data for recognition stored in a RAM (random access memory) card 7, and compares the digital signal from the A/D conversion circuit 5 with the recognition data stored in the RAM (random access memory) card 7. The second type is recognized and the recognition result is sent to the outside.

[0010] Here, the RAM card 7 can be freely attached to and removed from the device, and the stored basic data for recognition can be freely rewritten. Therefore, by rewriting the basic recognition data stored in the RAM card 7, different types of banknotes can be easily recognized using the same device.

[0011] In this way, a RAM that can be freely attached to and detached from the device
By using the recognition basic data stored in the card 7 to recognize the type of banknote 2 conveyed on the banknote conveyance path 1, the type of banknote to be recognized can be easily changed. For example, when using a banknote recognition device used in Japan in a foreign country, the basic data for recognizing banknotes used in the foreign country can be transferred to the RAM card 7.
Just write it in.

[0012] In one embodiment of the present invention, the RAM card 7
However, a plurality of ROM cards each storing basic recognition data according to the type of banknote 2 may be used, and the present invention is not limited thereto.

[0013]

Effects of the Invention As explained above, according to the present invention, banknotes are recognized based on recognition data stored in a memory card that can be freely attached to and removed from the device. This has the effect that the type can be easily changed.
