Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to input data inputted from an input means having various operation keys, and in response to a printing command given from the input means, continuous paper and its The present invention relates to a register having a dot-impact printer that prints on cut sheets inserted over continuous sheets.

[Prior art]

Conventionally, for example, P OS (point of 5a)
EcR (electronic cash regis) is one of the terminal devices in the system called EcR (electronic cash regis).
A register called ter) is used.

This type of register is designed to manage things such as the number of sold products, total sales, and change calculations, and most registers have at least a keyboard for inputting the names and prices of sold products. It is equipped with an input means and a printer that prints the data inputted from the input means, ie, the sales details showing the name, price, etc. of the sold products.

There are dot-impact type printers, but in conventional dot-impact printers equipped with registers, the printing force of the printing head on the paper is set to a constant level, and this printing force is equal to the printing paper. Settings are made to enable clear printing on paper depending on the gap between the print head and the print head.

Continuous paper such as roll paper is always inserted into the printer's printing unit, and the sales details are usually printed on this continuous paper. After printing on this continuous paper, the operator cuts the necessary portion of the continuous paper in the printing section and hands it to the customer who purchased the product as a receipt.

Incidentally, in some cases, a cut sheet such as a slip is inserted over an existing continuous sheet of paper in the printing section so that two sheets are stacked one on top of the other, and printing is performed on the upper cut sheet of the stacked sheet. In this case, naturally, the gap between the print head and the cut sheet became narrower than in normal use, and the printing pressure decreased, resulting in unclear print.

Therefore, in order to perform clear printing in such a printing form, there is a device constructed as follows.

It is equipped with an adjustment means for adjusting the voltage applied to the excitation coil for driving the print wire of the print head, and allows the operator to perform printing type B (printing on continuous paper and cutting paper stacked on continuous paper). Each time the form changes, an appropriate printing force is set by manually operating the adjusting means, taking into consideration the type of printing (printing, etc.).

[Problem to be solved by the invention]

However, in the conventional example described above, each time the printing format is changed, the operator has to take this into account and manually set the adjustment means, which not only takes a lot of effort, but also makes it difficult to determine which paper to use. The operator had to memorize the correspondence relationship of which stamping force should be used depending on the type of printing, which was troublesome.

The present invention has been devised in view of these circumstances, and by simply specifying the type of paper to be printed on, it generates the optimum printing force commensurate with the type of printing paper, making it possible to easily and stably print clearly. The purpose is to provide a registered register.

(Means for solving !I!llll) In order to achieve the above object, the present invention has the following configuration.

That is, the register according to the present invention, as shown in FIG. In a register equipped with a dot-impact printer 2 for printing on a cut sheet inserted over the continuous sheet, the input means 1 includes a designation means 3 for designating the type of sheet to be printed, and the The printer 2 can vary the printing force of the print head 4 on the paper during printing in Mm.
A printing force variable means 5 for changing the printing force, a storage means 6 in which the optimum printing force data for each Ili of the paper to be printed is stored, and a corresponding storage means 6 in response to the paper data from the specifying means 3. It is characterized in that it includes a control means 7 for controlling the operation of the stamping force variable means based on the stamping force data.

[Effect]

The effects of the configuration of the present invention are as follows.

When the paper data from the specifying means 3 is given to the control means 7, this control means 7 reads the stamping force data corresponding to the paper data from the storage means 6, and based on this stamping force data, the stamping force variable means 5 is controlled to set the printing force of the printing head 4 on the printing paper to an optimal condition, and the input data inputted from the input means 1 is printed.

In this way, the operator only needs to specify the type of paper to be used.

[Actual example]

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

An embodiment of the present invention is shown in FIGS. 2 to 8.

The print head 19 is moved by a carriage 21 in the print line direction.

The basic structure of this print head 19 will be explained with reference to FIG. That is, the printing head 19 is provided with a plurality of printing wires 25, and the printing wires 25 are driven forward and backward in the direction of arrow AB by an electromagnetic device 26.

The electromagnetic device 26 includes a U-shaped yoke 27, a coil 28 wound around one arm of the yoke, an armature 29, and a spring 30.

In the print head 19 having this configuration, the armature 29 is separated from the coil 28 (in the direction of arrow A) by the tensile force of the spring 30 when the coil 28 is not energized, and the magnetic force of the coil 28 when the coil 28 is energized. As a result, the armature 29 is pulled around the fulcrum O, and the printing wire 25 is made to protrude in the direction of arrow B. and,
In this embodiment, the supply voltage 9 is applied to the coil 28 by varying the energization time and application cycle using a drive circuit 43 shown in FIG. This corresponds to force variable means.

As a result, entry is made to the flowchart related to the operation of the printer side CPU 37 shown in FIG. 8, the paper data given from the register side CPU 31 is received in step S20, and the selected paper type is determined based on the received paper data in step 321. do. If it is determined in this step S21 that the paper is continuous paper P1, the process advances to step S22, and if it is determined that the paper is cut paper P8, the process advances to step 323.Step S22. S2
3 are processes for setting printing conditions (that is, the printing force applied to the printing paper by the print head 16, etc.), but the conditions are different. That is, in step 322,
The coil 2 of the printing head 16 is activated based on the printing force data read from the ROM 39 according to the selected paper type.
The voltage supplied to 8 is made relatively low, and the energization time is also made relatively short to set the application cycle to be short. On the other hand, in step 323, the supply voltage is made higher than the value set in step 322 based on the impression force data read from the ROM 39, and the energization time is also made longer to set a longer application cycle.

After that, in step S24, the print data given from the operation unit I3 through the register side CPU 31 is printed on the printing paper (this printing process is a well-known one, so its explanation will be omitted); In step S25, it is determined whether or not the printing has been completed. If the determination is YES, the above process is terminated, while if the determination is NO, the process returns to step S24 and is repeated until the printing is completed.

In the above embodiment, the paper types include printing on a single sheet of paper and overlapping printing, and a case is described in which the configuration is such that two types of printing are possible, but it goes without saying that the present invention is not limited to this. It can also be applied to those that perform printing formats. Furthermore, the structure of the print head 16 is not limited to that described in the embodiments, and in the embodiments, it is explained that both the supply voltage and the energization time are adjusted to vary the printing force. However, the configuration may be such that only one of them is adjusted.

〔Effect of the invention〕

As explained above, the register of the present invention allows the operator to automatically set the optimal printing force for the print head on the paper simply by specifying the type of paper to be printed on, making the operation extremely simple. This allows for stable and clear printing on each sheet of paper.

Therefore, according to the present invention, there is no need for the operator to remember the correspondence between the paper to be printed and the corresponding optimum printing force, and furthermore, the operator is freed from the troublesome work associated with adjusting the printing force. bring about an effect.

In addition, since the printing force can be set on the printer side according to each machine, when replacing the printer at the register for repairs etc., the printing force can be set for each printer using the input means or calculation means of the register. There is no need to readjust the hitting force, and it is only necessary to connect the input means of the register and the printer.
