Abstract

PURPOSE:To easily confirm transacted contents in the past by printing clock data at the time of the start of a journal and the clock data at the time of the finish of it on the endmost edge of a form immediately before the form is used up. CONSTITUTION:When it is decided that the remaining quantity of the form is less prescribed quantity, the clock data is read out of a clock circuit 10, and the read out result is stored by a finish time data storage means 9b. Further, the stored contents of a start time data storage means 9a and the stored contents of the finish time data storage means 9b are read out, and the read-out result is outputted to a printer driving means 5a, and is printed by its printer 5. Accordingly, the clock data at the time of the start of the journal and the clock data at the time of the finish of it are printed at the endmost edge of the form immediately before the form is used up. Thus, the transacted contents in the past become easy to confirm.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic cash register that is used as a standalone device or connected to a POS system or the like.

2. Description of the Related Art In conventional electronic cash registers, sales data is registered by storing the sales data entered using a keyboard or the like at the time of selling a product in a storage device such as an R/λM provided inside the device. This registered sales data is output to a printer to print receipts and journals.

The journal printed in this way is kept as a backup of the registered sales data.

Problems to be Solved by the Invention Generally, a journal printed by such an electronic cash register is a record of registered sales data printed in chronological order.

For this reason, based on requests from customers, past transaction details, etc.
For example, when checking sales data, etc. at a specific time, it is necessary to check all the journals that are wound up into a cylindrical shape and stored. This work is very laborious and requires a lot of time.

Additionally, in order to solve this problem, when the paper runs out while printing a journal, a process is carried out in which the end time of printing is written with a pen, etc. at the end of the paper. It is troublesome and there is a risk of forgetting this task.

Means for Solving the Problem In an electronic cash register that stores sales data such as sales amount inputted by an input means in a storage means and performs data processing such as printing of journals based on the stored contents of the storage means, paper Start time data reading means for reading out clock data from a clock circuit at a predetermined timing from after replenishment until the first journal printing is completed; and start time data for storing the read result by the start time data reading means. a storage means, a remaining paper amount determining means for determining whether the remaining amount of the paper is less than or equal to a predetermined amount, and the remaining paper amount determining means determines that the remaining amount of the paper is less than or equal to the predetermined amount. end time data reading means for reading out clock data from the clock circuit when the end time data reading means is executed; end time data storage means for storing successive results of the end time data reading means; and storage contents of the start time data storage means and the end time data. a start/end data reading means for reading out the stored contents of the data storage means; and a start/end data output for outputting the read result by the start/end data reading means to a printer driving means and printing by the printer. We have provided means.

The action start data reading means reads out clock data from the clock circuit at a predetermined timing from the time the paper is replenished until the first journal printing is completed, and the read result is stored by the start time data storage means; When the paper remaining amount determining means determines that the remaining amount of paper is less than a predetermined amount, the end data reading means reads clock data from the clock circuit, and the reading result is stored in the end data storage means; , the storage contents of the start time data storage means and the storage contents of the end time data storage means are read by the start/end time data reading means, and the read result is outputted to the printer driving means by the start/end time data output means. Print using a printer.

Therefore, the clock data at the start of the journal and the clock data at the end of the journal can be printed on the final edge of the paper just before the paper runs out.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 7. As shown in FIG. 2, this electronic cash register l includes a keyboard 2 as an input means, a cashier display 3, a customer display 4, a printer 5, and a drawer 6.
As shown in Fig. 3, its hardware configuration includes a CPU 7, a ROM 8, and a RAM.
9 are connected to form a microcomputer, and further, a display controller 3a to which the cashier display 3 is connected to the CPU 7, a display controller 4a to which the customer display 4 is connected; a keyboard controller 2a to which the keyboard 2 is connected;
A printer controller 5a serving as printer driving means to which the printer 5 is connected, a drawer controller 6a to which the drawer 6 is connected, and a clock circuit 10 are connected.

However, the ROM 8 contains information that controls the CPU 7 and is connected to the RAM 9, the display controller 3a, the display controller 4a, the keyboard controller 2a, the printer controller 5a, the trolley controller 6a, and the clock circuit IO. By exchanging various data and various commands, etc., fixed data such as programs for performing various tasks such as registration, inspection, and payment are stored.

Further, as shown in FIGS. 4 and 5, the RAM 9 includes a journal start time area 9a as a start time data storage means for storing clock data consisting of year, month, day, hour, and minute;
Journal end time area 9b as end time data storage means for storing clock data consisting of year, month, day, hour and minutes; a sales data area (not shown) as storage means for storing i-recorded sales data; a near end flag (not shown); (not shown)
, a print flag (not shown), etc. are provided.

In such a configuration, as shown in FIG. 1, when the journal printing process is started, the CPU 7 transfers the sales data stored in the sales data area of the RAM 9 to the printer based on the program stored in the R○M 8. The data is output to the controller 7a, and the journal is printed by a printer.

At the same time, as shown in FIG. 6, the paper remaining amount determination means determines whether the remaining amount of paper is less than a predetermined total amount (hereinafter abbreviated as "near end"), and if it is near end, Near-end detection processing is repeated at predetermined time intervals, in which the near-end flag is set to 1 and the near-end flag is cleared when the near-end is not detected.

Then, when the printing of the journal described above is completed, it is determined whether the near-end flag is 1 or not. It is determined whether or not this is the -th time after the paper was replenished.

However, as will be described later, this print flag is set to 1 when the paper is at the near end during the main journal printing process.

If it is determined that the print flag is 1, the start time data reading means reads the clock data (year, month, date, hour, and minute) from the clock circuit 1o, and then reads the journal start time area 9a.
, clear the print flag, and end the journal printing process.

Further, if it is determined that the print flag is not 1, no processing is performed and the journal printing process is ended.

On the other hand, in the process of determining whether or not the near-end flag is 1, if it is determined that the near-end flag is 1, after setting the print flag to l, the end data reading means reads the clock circuit. The clock data (year, month, date, hour, and minute) is read out from 10 and stored in the journal end time area 9b.

Furthermore, after the start/end time data successive output means reads out the stored contents of the journal start time area 9a and the stored contents of the journal end time area 9b, the start/end time data output means outputs these read results to the printer controller. 5a, and the printer 5 prints the data, thereby completing the journal printing process.

As shown in FIG. 7, the journal printed by the printer 5 as a result of such journal printing processing includes the clock data (year, month, date, hour, and minute) at the start of the journal and the end of the journal at the end of the paper 11. The clock data (year, month, date, hour, and minute) at the time is printed.

In this way, the clock data at the start of the journal and the clock data at the end of the journal are printed on the last edge of the paper 11 just before it runs out, so when checking past transaction details, etc. By simply checking the clock data printed on the last end of each journal wound into a shape, you can find the journal that records the transaction you are looking for, saving you the time and effort required to do so. It is possible to significantly shorten the time and at the same time make effective use of journals.

Effects of the Invention As described above, the present invention reads clock data from the clock circuit at a predetermined timing from the time when paper is replenished until the first journal printing is completed by the start data reading means, and reads out the read result. is stored by the start data storage means, and when the paper remaining amount determining means determines that the remaining amount of paper is below a predetermined whole body, the end data reading means reads clock data from the clock circuit, and the reading result is read out. The end time data storage means stores the stored contents, and the start/end time data reading means reads out the stored contents of the start time data storage means and the end time data storage means, and the read result is read at the start/# completion time. The data is output from the data output means to the printer driving means and printed by the printer. Therefore, the clock data at the start of the journal and the clock data at the end of the journal can be printed on the final edge of the paper just before the paper runs out. As a result, when confirming past transaction details, etc., you can simply check the clock data printed on the final end of each journal wound into a cylindrical shape, and the journal containing the desired transaction details can be retrieved. This greatly reduces the effort and time required in this case, and at the same time allows for effective use of journals.
