Abstract

PURPOSE:To prevent sale data dissipated even when no print output is obtained by prohibiting execution to clear the sale data when recording paper is exhausted in the middle stage of performing accounting processing. CONSTITUTION:It is discriminated whether or not the prescribed amount of recording paper remains when it is discriminated that input is registration input, and when only a small amount of recording paper remains and it is less than prescribed amount, no registration processing in which a message in message memory M3 without recording paper is read out, and is printed, displayed, and outputted is executed. When it is discriminated that the recording paper remains, it is discriminated whether or not unexecuted data exists by a scheduler, and when the contents of all the schedulers are executed in the past, the registration processing to update the data in sale data memory, etc., is executed. When an unexecuted scheduler exists, processing in accordance with the unexecuted scheduler, for example, the processing stored in scheduler memory M1 is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sales data processing device such as an electronic cash register or POS system that executes settlement processing.

[Prior Art] Conventionally, in a sales data processing device such as an electronic cash register (ECR), stored sales data is updated every time sales data is input (registered). It is generally known that there is a method disclosed in Japanese Patent Application Laid-open No. 1546i58/1983, in which the sales data is output when the sales data is completed, and the payment process is cleared for registration on the next day. There is.

[Problem to be Solved by the Invention] However, if the operator leaves the place for some errand after specifying to execute the payment process, and the recording paper for printing runs out,
There was an inconvenience that the sales data was cleared before the sales data could be output, resulting in the sales data being lost.

The reason for this is that even if the recording paper runs out, the payment process is executed to the end and the sales data is cleared.

It is clear that if the payment processing is interrupted and the sales data is not cleared when the recording paper runs out, the sales data will not be lost.

An object of the present invention is to make it possible to prohibit clearing of sales data when recording paper runs out during payment processing.

[Means to solve the problem] The means of this invention are as follows.

Input means A (see the functional block diagram in Figure 1; the same applies hereafter)
enter sales data.

The sales data storage means B stores the sales data inputted from the input means A.

The printing means C prints the sales data stored in the sales data storage means B on recording paper.

The recording paper detection means detects the presence or absence of recording paper in the printing means C.

The settlement control means E executes a settlement process of printing and clearing the sales data in the sales data storage means B by the printing means C.

[Action Co. The operation of the means of this invention is as follows.

The sales data input from the input means A is stored in the sales data storage means B, and the sales data in the sales data storage means B is recorded by the printing means C as the payment processing is executed by the payment control means E. Printed on paper and cleared. In this case, if the recording paper detection means C detects that there is no recording paper in the printing means C, clearing of the sales data stored in the sales data storage means B by the settlement control means E is not executed.

Therefore, if the recording paper runs out during payment processing, clearing of sales data can be prohibited.

[Example] An example will be described below with reference to FIGS. 2 and 3.

In this embodiment, the present invention is applied to an electronic cash register (ECR).

Figure 2 is a block diagram of the ECR. The ECR processes sales data with the CPU 1 at its core. and a drawer 8 are connected. Then, the CPU 1 performs various processing on the sales data inputted from the key personnel section 2 according to a program stored in advance in the ROM 3, stores the processing results in the RAM 4, displays them on the display section 6, and prints them out on the printing section 7. etc.

The key input unit 2 includes a number key 2aN, a function key 2b1 for inputting function information, and a current/deposit key 2.
CN clear key 2d, settings, registration, power OFF
It has a mode changeover switch 2e for switching between F, inspection, and payment modes. In addition, mode changeover switch 2
e settings are for setting data for presets, registration is for normal money transfers, power OFF is for not using ECR, inspection is for reading stored data without clearing it, and payment is for storing stored data. Used to clear after reading.

The RAM 4 includes a schedule memory M1, an error message memory M2, a message memory without recording paper M3, a sales data memory M4, and other memories. A command area where commands are stored, a start time area where the time to start execution of each of the above processes is preset, an unexecuted flag area where a flag indicating that the scheduler could not be started, and messages corresponding to the contents of each command are stored. It is made up of a message area to be stored. Then, when the payment process is started at the time set in the schedule memory M1, when the recording paper such as journal paper and receipt paper provided in the printing section 5 is about to run out, M2 displays a message on the payment report. For example, message data such as "Kirokushigire@Zchuushi" is stored to indicate this. M3 also stores a message that is printed and displayed when the recording paper is about to run out, such as "Kirokushigire Kokansurukoto". Although not shown, the sales data memory M4 is configured to store sales data such as unit price, character, and number of units sold for each product. It will be updated. Further, the number of sold items in the sales data memory M4 is cleared after the payment is made.

The clock circuit 5 measures and stores the current time, the display section 6 displays input sales data, etc., and the printing section 7 includes recording paper such as receipt paper and journal paper.
This device is equipped with a sensor that detects when the amount of recording paper has fallen below a predetermined amount. This sensor is composed of, for example, a pair of optical light-emitting section and light-receiving section. In this case, the light from the light emitting part is blocked by the roll paper, and when roll paper is used and the diameter becomes small, the light from the light emitting part enters the light receiving part to detect a near end without roll paper. The drawer 8 is for storing money and the like.

Next, the operation of this embodiment will be explained.

FIG. 3 is a diagram showing the overall operation of the ECR.

First, this ECR executes the scheduler, so even if the mode selector switch 2e is turned off, if the power line (not shown) is connected, the input will be invalid, but internal processing will be possible, and when the power starts being supplied, the ECR will be disabled. Proceeding to step S1, it is determined whether any input has been made from the key human power unit 2. If no input has been made, the process proceeds to step S2, where the current time of the clock circuit 5 and the start time of either of the schedule memory M1 are determined. If the scheduler matches, it is determined whether the scheduler contents should be executed, and if the scheduler is to be executed, the process proceeds to execute the command contents corresponding to the matched time, which will be explained in detail later (step S3).
. Further, even if there is some input in step S1 when the mode selector switch 2e is in the OFF position, the process proceeds to step S2 and the same processing as described above is performed.

Further, if the mode selector switch 2e is in a position other than the OFF position and it is determined that some input has been made in step S1, the process proceeds to step S4, where it is determined whether the input is product data input, that is, registration input, and if preset etc. If the input is other than the registered input, processing according to the input content is executed. (Step S5). However, if it is determined in step S4 that it is a registration input, check whether there is more than a predetermined amount of recording paper or step S4
If the remaining recording paper is less than a predetermined amount, the process proceeds from step S6 to step S7, where the message from the message memory M3 without recording paper is read out, printed, and displayed. If it is determined in step S6 that there is recording paper, the process advances to step S8.
In this step S8, it is determined whether there is an unexecuted flag in the scheduler memory M1 to determine whether there is an unexecuted scheduler, and if the contents of all schedulers have been executed in the past, the unexecuted flag is flagged. Since all have been cleared, the process advances to step S1, where registration processing such as updating the data in the sales data memory is executed, and step S1
Return to Also, if there is something unexecuted in the scheduler,
For example, the Z message "Seisan Mishuuryo" stored in the scheduler memory M1 corresponding to the unexecuted scheduler is printed (step 510).
). Then, the process proceeds to step S1, where it is determined whether the unexecuted scheduler is a payment process, and if it is not a payment process, the process proceeds to step S12, where the process of the unexecuted command content is executed. Further, when it is determined in step Sll that the payment is to be made, the sales data stored in the sales data memory M3 is read out for each product, and the print unit 7 prints it on the rent and journal (step 513), after which,
When it is determined in step S14 that all the sales data of the sales data memo UM3 has been printed, the process proceeds to step S15, and a process (step 515) is performed to clear the sales data such as the number of sales items of the sales data memo UM3. Ru.

Furthermore, step S12 and step S13.14.1
When the scheduler contents are executed in step 5,
Proceeding to 1f3, the unexecuted flag corresponding to the scheduler memory M1 in which the executed scheduler command is stored is cleared, and it is determined in step S17 whether an unexecuted flag is stored separately, and if there is another unexecuted flag. If it has been stored, the process returns to step Sll and the above-described operations are repeated, but if all of the unexecuted schedule contents have been executed, the process returns to step S17 to step S.
Return to 1.

In this way, when the first registration is performed after operating the mode selector switch 2e and turning on the power, if there is no recording paper in the determination in step S6, the process advances to step S7 to prompt the replenishment of recording paper, and When paper is replenished, if the scheduler has been interrupted in the past as determined in step S8, the process proceeds to step S9.The first registration is deemed invalid and the process proceeds to step S7, where the scheduler is automatically executed with priority. do.

Next, FIG. 4 is a diagram showing a part of the operation of the ECR, and shows a process that starts when the current time of the clock circuit 5 and the start time of any one of the scheduler memories M1 match, and shows the process that starts in step S3 described above. FIG.

First, in step S31, it is determined whether the command data corresponding to the matching start time is a payment command (Z command) for executing payment processing (step 5
32). Then, if it is determined in this step S32 that it is a Z command, the payment process is executed below.
In the settlement process, when it is determined in step S33 that there is a predetermined amount or more of recording paper in the printing section 5, the sales data stored in the sales data memory M3 is read out for each product, and
The printing unit 7 prints on the receipt and journal (step 534). Thereafter, when it is determined in step S35 that all the sales data in the sales data memory M3 has been printed, the process proceeds to step 83B, where the sales data such as the number of sold items in the sales data memory M3 is cleared and the settlement process is ended. However, in step S35, the sales data memory M
If it is determined that all of the sales data of No. 3 is not printed, the process returns to step S33. In addition, if it is determined in step S33 that the recording paper provided in the printing unit 5 is not more than a predetermined amount (near end without paper, etc.), the process proceeds to step S37, interrupts the execution of the payment process, and reads the payment command in the scheduler memory M1. Turns on the corresponding non-execution flag, prints an error message on recording paper (step 538), performs payment processing,
The data in the sales data memory M3 is not cleared.

Further, if it is determined in step S32 that the command is other than a payment command, the process advances to step S39 and processing in accordance with the contents of the command is executed.

[Effects of the Invention] According to this invention, if the recording paper runs out during the payment process, the sales data is not cleared, so that the sales data disappears even if the recording paper runs out and no printout is obtained. can be prevented.
