Description

[Detailed description of the invention] [Industrial application field] This invention relates to improvements in electronic cash registers.

[Prior Art J] Conventionally, in an electronic cash register, when sales data of a product is inputted from, for example, a keyboard, the sales data is edited as print data and always printed out by a printer. Further, for example, if a printer runs out of paper, the operation of the printer is prohibited, so input of product sales data from the keyboard is prohibited.

[Problems to be solved by the invention] However, with such conventional devices, printing is always performed even when there is no need to issue a receipt, such as for maintenance work or cashier training, or when there is no need to print a journal, which reduces the lifespan of the printer. However, there was a problem in that paper was wasted. Furthermore, there is a problem in that when there is no paper in the printer, it becomes impossible to input product sales data, which hinders business operations.

This invention was made to solve these problems, and it is possible to perform business even when the printer's functions are stopped, and therefore, it is possible to perform business even when the printer is out of paper, and it is possible to perform printing even when the printer's functions are stopped. It is an object of the present invention to provide an electronic cash register in which data can be printed out later.

[Means for Solving the Problems] The present invention sets the operating state and stop state of the printer function in an electronic cash register that registers product sales data in a memory and prints out the sales data using a printer. a means for controlling the output of print data to the printer when the printer function is set to an operating state, and storing the print data to a storage memory without outputting it to the printer when the printer function is set to a stopped state; The apparatus is provided with storage control means and means for restoring the printer function from a stopped state to an operating state and controlling the output of print data in the storage memory to the printer.

[Function] In the present invention having such a configuration, the printer function is set to a stopped state, for example, when the printer runs out of paper or when printing is not required due to maintenance work, cashier training, etc. With this setting, product sales data is registered in the memory, but the print data of the sales data is stored in the storage memory without being output to the printer.

If the paper runs out, the printer can print by setting paper later. However, by restoring the printer function from the stopped state to the operating state in this lever state, the print data stored in the storage memory is printed out by the printer.

In this way, it becomes possible to print the sales data of the product that was previously input.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

In addition to the memory necessary for registering product sales data, the RAM 3 stores a print flag 31, a number buffer memory 32, a storage buffer memory 33, and a print buffer 1, as shown in FIG.
A memory 34 and the like are provided.

The keyboard 7 has number keys 71 as shown in FIG.
, a clear key 72 used for erasing the data set by the numeric key 71, and a PLLJ (price look up) key 7 used for registering single items.
3. Subtotal key 74 for displaying subtotal data during product registration 1. Various keys such as total key 75 are provided, which are used in various operations such as closing registration for customers and setting conditions in maintenance operations. It is being

The CPU 1 performs various controls and processes based on key signals from the keyboard 7, especially the numeric key 71 and the total key 7.
If there is key human power of 5, the processing shown in FIGS. 4 and 5 will be performed.

FIG. 4 shows the numeric key processing. When the numeric key 71 is pressed manually, the numeric data is stored in the buffer 33.

FIG. 5 shows total key processing in maintenance work. In this work mode, if there is key power for the total key 75, a check is made in advance to see if there is a numeric input using the numeric key 71. If there is no numeric key input, an error will occur. Also, if there is a number key input, the next number input will be "1"
, r2J, r3J, or other data. If the input power is "1", the print flag 31 is turned on, and the contents of the storage print buffer 33 are controlled to be output to the printer 11 via the printer/drawer interface 1°. Further, if the numeric input is "2", the print flag 31 is turned on.

Also, if the numeric input is r3J, turn off the print flag 31.
do. Further, if it is other than that, an error occurs.

Further, the CPU 1 performs the printing process shown in FIG. 6 when product sales data is input in the "registration" mode.

This is from the keyboard 7, for example, the numeric key 71 and PL (J
A single item code is input using the key 73, and based on that, the RA
When the registration process is performed on the memory in Ma, print data revealing it is stored in the print buffer 34 for printing. Next, it is checked whether the print flag 31 is turned on. If the print flag 31 is turned on, the contents of the print buffer 34 are output to the printer 11 and printed. Further, if the print flag 37 is OFF, the contents of the print buffer 34 are stored in the storage buffer 33.

That is, use the number key 71 to enter "2" and press the total key 7.
The process of cpu i when operating 5 indicates a means to set the operating state of the printer function, and the numeric key 71 is used to
cpv' when inputting 3J and operating total key 75
The + processing indicates means for setting the stop state of printer entertainment. In addition, when the number key 71 is used to input ``1j'' and the total key 75 is operated, the CPU i process recovers the printer from the stopped state to the operating state and prints out the print data in the storage buffer memory 33. It shows the means to do so.

In the embodiment of the present invention having such a configuration, in the "maintenance" mode, if the number "2" is entered using the number key 71 and the total key 75 is operated, the print flag 31 is turned on. However, in this state, when the mode switch 5 is set to the "registration J mode" and product sales data is registered, the print data is stored in the print buffer 1 memory 34 and then output to the printer 11 and printed.

Further, when the paper runs out, in the "maintenance" mode, enter "3" with the Wl number key 71 and operate the total key 75. As a result, the print flag 31 is turned off.

When the mode switch 5 is set to the "registration" mode and product sales data is registered, the print data is stored in the print buffer memory 34 and then stored in the storage buffer 33 without being output to the printer 11. After that, set the paper in the printer 11, enter "1J" with the number key 71 in the "maintenance" mode, and operate the total key 75. As a result, the print flag 31 is turned ON and the print data in the storage buffer memory 33 is The data is output to the printer 11 and printed.In this way, when the printer □ function is stopped due to paper shortage, the registered data can be restored from the stopped state to the operating state and printed out.

In addition, when performing pseudo registration processing in maintenance work, printing by the printer 11 is not necessary, so the number of strokes key 71 is used.
Enter "3" and operate the total key 75 to set the print flag 3.
1 as ONL, and then perform the registration operation. In this case, there is no need to restore the printer function to the operating state and print the data in the storage buffer 7 memory 33.

In this manner, when the printer 11 runs out of paper or when pseudo registration is performed for maintenance, the printer function can be stopped and product sales data can be registered. Moreover, the print data of the registered data is stored in the storage buffer memory 33 after stopping the printer function, and then the printer 1
1 can be printed out.

Therefore, wasteful use of paper and wasteful operation of the printer 11 can be prevented. In addition, normal registration work can be carried out without paper.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to perform business with the printer's functions stopped, and therefore, it is possible to perform the business even when the printer is out of paper, and moreover, it is possible to perform the business even when the printer is out of paper. It is possible to provide an electronic cash register that can be printed out later.
