1. TECHNICAL FIELD

The invention relates to the technical field of bill management, in particular to a bill binding and encoding device and a classification filing system.

2. BACKGROUND ART

The various types of bills are essential for the operation of today's social organizations, accompanying the life cycle of each organization from its emergence to its dissolution, and serving as important documents of proof or for inspection by the relevant authorities at the required time.

For every organization, especially those with frequent social activities, there emerge a large number of bills and the storage and management of these bills is a time-consuming task. The existing bill management usually binds the same type of bills for a period of time such as one month, and then places the same type of bills of different time periods after binding into a book, with arranging them in chronological order for easy subsequent search and management.

However, by adopting such bill management method, it is easy to disrupt the chronological order after taking out and putting back the bill book several times when looking for the required bills, resulting in frequent inaccuracies in the subsequent search by chronological order and confirmation requirement by looking up the contents of the bill book, which leads to a lot of time waste for each bill search.

For organizations with frequent social activities, it is even more troublesome to search for bills each time as they have more bills.

It is possible to pull the exposed end of the ink ribbons 41 directly when being used next time, avoiding the time consumption of finding the end.

The surface of the press roll 36 has a release layer. The release layer is a release paper or a release film provided on the surface of the press roll 36. Since the adhesive surface of the ink ribbons 41 are in contact with the press roll 36 when the ribbons 41 are pulled, providing the release layer on the surface of the press roll 36 can prevent the ink ribbons 41 from sticking to the press roll 36, resulting in difficulty in pulling and destruction of the adhesion.

One end of the press roll 36 is fixed and the other end is unlocked, so that the ink ribbon 41 can be inserted from the unlocked end when the ink ribbon 41 is put in for the first time.

Referring to the FIG. 10 to FIG. 12, further, the surface of the first arc-shaped elastic sheet 31 is provided with the electrostatic generation layer 311; and the surface of the second arc-shaped elastic sheet 33 is provided with the electrostatic generation layer 311.

The electrostatic generating layer 311 is provided for generating static electricity by friction between the ink ribbons 41 and the electrostatic generating layer 311 when pulling and moving the ink ribbon 41, and the generated static electricity can cause the smooth surface of the ink ribbons 41 to attach to the first arc-shaped elastic sheet 31 and the second arc-shaped elastic sheet 33, shaping the ink ribbons 41 pulled out to prevent the ink ribbons 41 from being arched. Thereby, when pressing the bill book 50 into the encoding groove 13, the ink ribbons 41 can be attached to the bill book 50 in a predetermined position.

Referring to the FIG. 3 and FIG. 14, further, the supporting column 241 is provided at one tail end of the installation cylinder 24; the length of the installation cylinder 24 is equal to the width of the plurality of ink ribbon spools 40; one end of the installation cylinder 24, which is far away from the supporting column 241, is provided with the thread groove, and the fixing nut 242 is in screw-thread fit with the thread groove; the fixing spring 243 is provided on the installation cylinder 24 in the penetrating mode and is provided between the ink ribbon spools 40 after being mounted and the fixing nut 242.

When encoding, multiple colored ink ribbons 41 can be applied for deeper encoding, such as one color for the year plus one color for the month, and one color for the type plus one or more colors for the time period, as referring to the FIG. 16.

The installation cylinder 24 can be installed with a variety of colored ink ribbons 41 for encoding. When installing or replacing the ink ribbons 41, removing the fixing nut 242 and fixing spring 243, then installing one or more kinds of ink ribbons 41, then installing the fixing spring 243 and fixing nut 242 in turn, and the fixing spring 243 is arranged tightly with the ink ribbons 41.

Referring to the FIG. 2 and FIG. 3, further, indication scales 15 are further provided on one side of the sliding rail 11, and the scales of the indication scales 15 are provided in corresponding to the positioning teeth 121 in sequence one by one; the control block 26 is provided with the indication mark 261 pointing to the indication scale 15.

For example, when adopting the month for encoding, the indication scale 15 is set to 1-12, and moving the sliding block 21 to move the indication mark 261 to the selected indication scale 15, which means the numbering of that position on the bill book 50.

The invention further provides a classification filing system, comprising the above bill binding and encoding device.

By encoding the bound bill book 50 and then classifying and filing the encoded bill book 50, the invention allows the quick finding and returning during subsequent administration.
