Description

Paper transfer guide of cash register printer

The present invention relates to a paper transfer guide device for a cash register printer, and more particularly, by reducing the load during paper feeding by using a paper guide and a freely rotating roller. It relates to a paper transfer guide device for a cash register printer to provide a printing environment.

In general, a cash register installed in convenience stores, supermarkets, restaurants and department stores is a device that performs functions such as transaction history, sales amount calculation, tax calculation, receipt issuance, and the like. As input, the corresponding amount is displayed on the display device, and a receipt is output through the printer device.

Here, the term "printer" refers to a device in which a printer device performing printing, and a printer body in which a printer device and a printer paper are accommodated are combined.

On the other hand, a printer mounted on a conventional cash register uses a roll type printer paper as an output device of a cash register which prints a transaction history and issues a receipt and an audit paper. The printer using such a roll-type printer paper is provided with a separate storage space for storing the printer paper, the printer paper is configured to be integrated into the paper input port of the printer device by the user.

A perspective view showing the appearance of a printer mounted on a general cash register is shown in FIG. 1, and a diagram showing a process in which printer paper is discharged after being fed into the printer device and printed is shown in FIG. 2.

As shown in Fig. 1 and Fig. 2, a printer device 2 for printing transaction details is mounted in the printer main body 1, and a roll-shaped printer paper 3 supplied to the printer device 2 is provided. The adjacent point of the printer apparatus 2 is accommodated. Here, the roll-shaped printer paper 3 is mounted to be rotatable by the support member 4 extending in the vertical direction from the bottom of the printer body 2.

With this structure, when the user inserts the end of the printer paper 3 into the paper insertion opening of the printer device 2 and inputs the paper feeding key among the plurality of function keys mounted at the predetermined position of the printer body 1, The printer paper 3 is fed to the printer apparatus 2, printed, and ejected to the outside of the printer body 1.

3 and 4, a paper guide 5 for guiding the inserted paper is integrally mounted to the printer device 2 at the paper input port of the printer device 2. This paper guide 5 not only guides the printer paper 3 to be inserted so that the user can easily insert the printer paper 3 into the printer device 2, but also the printer paper 3 that has already been loaded is not attached to the printer device. It serves to prevent the printer paper 3 from being separated when it is fed to (2).

By the way, in the case described above, since the paper guide 5 is integrated with the printer device 2, when the printer paper 3 is fed to the printer device 2 in a folded state, as shown in FIG. A sliding phenomenon occurs between the printer paper 3 and the paper guide 5. Therefore, in order to overcome this sliding phenomenon, the printer device 2 must pull a strong force to pull the printer paper 3, and this causes a problem in that the printed font shape is distorted (distorted).

In addition, when the printer paper 3 is replaced, since the weight and volume of the printer paper 3 are the largest, the printer device 2 is a printer paper in order to feed the printer paper 3 to the printer device 2. (3) Since the pulling force must be stronger, there is a problem that the distortion degree of the printing state is increased.

In addition, there is a problem that the printer paper (3) was fed when the printer device (2) is too strong to pull the printer paper (3).

Therefore, the present invention is to solve the above-described problems, the object of the present invention is to add a roller that is freely rotated in front of the paper guide, and the printer paper is applied to the printer paper by supplying the printer device through the roller, The present invention provides a paper transfer guide device for a cash register printer which reduces power and provides an optimal printing environment.
