Description

Device for preventing paper unwinding of cash register.

The present invention relates to a cash register used for sales calculation, tax calculation, receipt issuance, etc. in convenience stores, supermarkets, restaurants, etc., and more particularly relates to a cash register of the cash register that can stably feed the printer paper toward the printer. .

Typically, the cash register has a cash drawer for storing cash as shown in Figs. 1 and 2, and also has a calculator having a calculation function and a paper 42 as an ink ribbon for printing a receipt. A printer 44 is provided for printing the contents calculated in the board (calculated), and a pulley 24 for seating the paper 42 to be printed on the paper mount 18 is provided. In this case, as shown in FIG. 3, the shaft 26 of the pulley 24 having the paper 42 inserted therein is seated in the opening 40 formed at the upper end of the paper mounting table 18. .

When a conventional cash register configured as described above performs a printing process, first, when one end of the paper 42 is supplied toward the entrance of the printer 44, the pulley 24 and the paper 42 are wound and rotated. 42 is supplied to the printer 44 while being unwound. After that, the printer 44 performs the printing process while pulling the paper 42.

However, the cash register configured as described above is rotated by the pulling force of the printer when the printer finishes the printing process because the shaft of the pulley into which the paper is inserted is seated from the top to the bottom without receiving a predetermined force from the opening of the paper holder. The shaft of the pulley being rotated continues to rotate due to the inertia force to rotate. Due to this, there is a problem that the paper jam phenomenon occurs while the paper is continuously unwound and fed to the printer crookedly.

In order to solve the above problems, the purpose of the present invention is to mount the shaft of the pulley in which the paper is inserted into the paper mounting table at a constant pressure (force), so that the paper jam prevention device of the cash register that can prevent the paper jam from the printer side To provide.

Another object of the present invention is to provide a cash register preventing device of the cash register that can prevent the paper from further unwinding when the printer stops printing.

Another object of the present invention is to provide a paper register preventing device of the cash register that can prevent the paper inserted in the pulley to be inclined into the printer.

In order to achieve the above object, the present invention provides a cash register having a pulley for inserting a sheet of paper into a paper mount and a printer for printing the sheet of paper with an ink ribbon, wherein the cash register includes a sheet of paper fitted to the pulley. The spring is provided with a constant compression force is inserted into the groove of the paper support in order to prevent the paper from being unwound excessively when is supplied to the printer while being released.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Figure 4 is a perspective view showing the shape of the spring to prevent the paper is mounted on the paper support of the cash register according to an embodiment of the present invention. Figure 5 is a cross-sectional view showing a state in which the paper and the pulley is mounted on the paper support of the cash register according to an embodiment of the present invention.

As shown in FIGS. 4 and 5, the cash register has an opening 22 of the paper support 18 so that the pulley 24 having the paper 42 inserted into the paper support 18 is seated under a constant force. Spring 10). That is, the spring 10 is formed of a leaf spring having a constant elastic force to prevent the paper 42 from being excessively loosened when the paper 42 inserted into the pulley 24 is supplied toward the printer 44 while being unwound. do. And, both sides of the spring 10 is formed with each fixing portion 12 is fitted into the grooves 20 formed on both sides of the opening 22 of the paper support 18, the center of the spring 10 The seating portion 16 seated in the opening 22 of the paper support 18 to mount the shaft 26 of the pulley 24 is formed to be rounded (rounding) smaller than the radius of the shaft 26 have.

Referring to the operating state of the paper unwinding device of the cash register of the present invention configured as described above are as follows.

First, the fixing parts 12 formed on both sides of the spring 10 are inserted into the grooves 20 of the paper mounting table 18. At this time, the seating portion 16 of the spring 10 is naturally seated in the opening 22 of the paper mount 18 receives an elastic force in the direction of the central axis. Thereafter, the shaft 26 of the pulley 24 into which the paper 42 is inserted is inserted into the seating portion 16 of the spring 10. At this time, the shaft 26 is subjected to a predetermined pressure.

Then, when one end of the paper 42 is fed to the printer 44 inlet and then printing is performed, the pulley 24 and the paper 42 are rotated to unwind the paper 42 while the printer 42 is unwound. It is supplied to). After that, the printer 44 performs the printing process while pulling the paper 42. Thereafter, when the printing process of the printer 44 is completed, the printer 44 no longer pulls the paper 42, and at the same time, the shaft 26 of the pulley 24 is driven by friction with the spring 10. The rotation is stopped and the paper 42 stops without being unloaded anymore, thus ending the printing process.

As described above, in the cash register preventing device of the cash register according to the embodiment of the present invention, the frictional force between the pulley and the spring cancels out the property of the paper being released due to the inertia force when the printing operation of the printer is stopped. Can be stopped quickly, and the next time the next printing operation is performed again, the paper state is always fed in parallel with the entrance of the printer to prevent the paper from skewing and to prevent the paper jam phenomenon. It has an effect.
