Description

Detailed Description of the Invention The present invention provides an electronic cash register that prints slip authentication print data in a line using both a receipt printing section and a journal printing section. This invention relates to an electronic cash register which is capable of dividing data into two parts and printing slip authentication in one printing part twice.

For example, with electronic cash registers used in restaurants, slip authentication is often performed in which the registered total amount is printed on a slip that describes the customer's ordered items as a receipt. It is inserted into the slip insertion slot, and by operating the slip authentication key, the date, series number, amount, etc. are printed on the slip, and it is used as a receipt.

Conventionally, with this type of printer, authentication print data is printed on the slip using both the receipt print section and the journal print section due to the number of printing digits, but when the width of the slip is narrow, all of the authentication print data is printed on the slip. cannot be printed.

Therefore, only slips of a certain width could be used.

This invention was proposed to solve the above-mentioned defects, and for narrow-width slips, a cash register is provided in which authentication print data can be printed twice on either the receipt print section or the journal print section. The purpose is to obtain.

An embodiment of the present invention will be described below with reference to the attached drawings. FIG. 1 is a perspective view of a cash register;
It is equipped with a keyboard 1, a display 2, a drawer 4, a built-in printer, a receipt output port 5, and a slip insertion port 6.

, clear key 9, deposit/total key 10 for finishing registration and totaling for one customer, person in charge key 11, control key having registration, inspection, payment, setting, lock, and H positions and selecting the machine operation mode. 12, etc., and a slip authentication key 13 that is operated when printing slip authentication.

FIG. 3 is a schematic diagram of a built-in printer, in which the printer 14 has a receipt printing section and a journal printing section (not shown), and a slip insertion groove adjacent to the back side of the slip insertion slot 6 on the top surface. The slip 16 inserted into the slip 15 can be printed on both sides when the slip width is wide, or on one side when it is narrow.

17 is a receipt paper, and 18 is a journal paper.

Also, inside there is a slip detection switch 19, which is made of, for example, a photoelectric element, to detect the presence or absence of a slip, and a slip detection switch 19, which is located at the minimum width that allows printing both the receipt printing section and the journal printing section in a row. A slip width detection switch 20 is provided to detect whether the slip width is above or below the limit width.

FIG. 4 is a block diagram showing the circuit configuration of this cash register, in which key manual signals generated by key operations on the keyboard 1 are encoded through a display keyboard interface (hereinafter abbreviated as D/K interface) 21 and sent to the central processing unit as key data. (abbreviated as Itcho CPU) 22, and the CPU 22 uses the read-only mode in which the program is stored according to the key data.
It decodes instructions in a memory (hereinafter referred to as ROM) 23, reads or writes data to a random access memory (hereinafter referred to as RAM) 24 that stores data, performs arithmetic processing, or operates the D/K interface. 21, the data is displayed on the display 2, or the data is printed on the printer 14 via the blink interface 25.

A first slip print buffer 2 provided in the RAM 24
6, for example, series No. 6. , the amount, and the transaction, and the date in the second slip print buffer 27. Also, it is set when the slip authentication key 13 is operated for the first time, and reset when it is operated for the second time. There are provided an authentication operation flag 28 that is set when the slip width detection switch 20 detects a slip, and a slip width flag 29 that is set when the slip width detection switch 20 detects a slip.

The detection signals from both detection switches 19 and 20 are
When the slip detection signal is input to the CPU 22 via the input keyboard 30, a slip lamp (not shown) provided on the display 2 is lit, and when the slip width detection signal is input manually, the slip is detected. When the width flag 29 is set and the slip authentication key is operated in this state, the slip width flag 29 is set.
is set, the journal print section prints the data on the first slip print buffer 26, and at the same time, the receipt print section prints the data on the second slip print buffer 2.
γ data is printed, and if the slip width detection signal is not input, the slip width flag 29 has been reset, so judge this and print the data on the first slip print bus sofa 26 using only the journal print section on the slip. is printed, the authentication operation flag 28 is set, the slip authentication lamp (not shown) provided on the display 2 is lit, and the other subsequent keys are disabled, and the slip authentication key 13 is then pressed again. When operated, the data in the second slip print buffer 27 is printed and the slip authentication lamp is turned off.

The operation of the present invention having the structure as described above will be explained. When the operator follows the slip in which the items ordered by the customer are written, registers the amounts of those items, and operates the deposit/cash key 10,
The total amount is calculated and displayed on the display 2, and printed on the receipt and journal.

Here, when a slip is inserted into the slip insertion groove 15, the slip detection switch 19 detects that the slip has been inserted and sends a signal to the CPU 22 via the manual port, and the CPU 22 judges this and lights up the slip lamp. .

Now, if the slip is narrower than the limit width, the slip width flag 29 remains reset because no signal is input from the slip width detection switch 20.

Subsequently, when the slip authentication key 13 is operated, the authentication operation flag 28 is set, the slip authentication lamp is turned on, and the data in the first slip print buffer 26, that is, the series number. , amount, and transaction are printed on the slip using the journal printing section.

At this time, even if a key other than the slip authentication key is operated, no input is made and an error occurs.

Next, if the slip is inserted upside down and the slip authentication key 13 is operated again, the setting of the authentication operation flag 28 is determined, and the data, that is, the date, in the second slip print buffer 27 is printed on the slip by the journal print section. Print (see Figure 6a).

In this way, even authentication print data with a large number of digits can be printed twice on a narrow slip.

In addition, if a slip wider than the limit width is inserted, λ sets the slip width flag 29 by a signal from the slip width detection switch 20, and when the slip authentication key 13 is operated, it is determined that the receipt printing section and the journal Both printed parts are serial No.・Print the amount, transaction, and date at the same time.

(See FIG. 6b) As described above, the authentication print data can be printed on the slip once or twice depending on the slip width.

In the second invention, the operation selection between printing once and printing twice is possible by pressing the slip authentication key twice.
Types are provided so that the operator can select one.

That is, the keyboard has a first slip authentication key and a second slip authentication key.
A slip authentication key is provided, and in response to the operation of the first slip authentication key, the data in the first slip print buffer 26 is simultaneously sent to the journal print section, and the data in the second slip print buffer 27 is simultaneously sent to the receipt print section. When printing on a slip and operating the second slip authentication key, the data 26 of the first print bus sofa is printed on the slip in the journal print section, and the slip is reinserted upside down and the second slip is inserted again. When the authentication key is operated, the data in the second slip print buffer 27 is printed on the slip by the same journal printing section.

Of course, the receipt printing unit may also print the information.

With this configuration, if the width of a slip is above a certain limit, the first slip authentication key is used to print it once, and if it is below a certain limit, the second slip authentication key is operated twice to print the slip. It can be printed separately on the top and bottom.

In addition, instead of operating the second slip authentication key twice, a third slip authentication key is provided, and the second slip authentication key is operated to print the first slip print buffer 2 in the journal printing section.
After printing the data in the second slip print buffer 27, the third slip authentication key may be operated to print the data on the second slip print buffer 27 on the receipt printing section.

As explained above, according to the cash register of the present invention, it is possible to print authentication print data in two times even on narrow slips where both the receipt print part and the journal print part cannot be printed in one line. This has the excellent effect of widening the scope of application and increasing versatility.
