Description

[Detailed description of the invention] [Industrial application field] This invention stores date information including year, month, day, etc., and changes this date information as necessary to print it on slips, etc. Related to date changing devices for electronic devices such as those displayed on CRTs, etc.

[Summary of the idea]

The present invention provides a memory that stores date information separately from a clock circuit that generates date information, and allows the date information in this memory to be changed arbitrarily. It allows you to change the date information without destroying the information.
Moreover, this changed date information in the memory can be easily converted into the generated date information.

[Conventional technology]

In recent years, many electronic computers such as so-called office computers and electronic cash registers print the current date on printed paper such as slips.
In the case of conventional devices of this type, the current date is preset in the memory each morning by key input from the key input device or by operating an external switch, or if the device is equipped with a clock device, the date is not printed. Each time, the current date is read out from the clock device and printed.

[The problem that the idea attempts to solve]

By the way, with the above-mentioned devices, generally, due to circumstances such as issuing slips (for example, when it is revealed from the slip that the customer brought in that there is a defect in the slip issued one week ago, and it is necessary to reissue it), There are times when it is necessary to print a date other than the current day, and in that case, the preset date is changed to deal with it, but there was a problem that the date had to be changed again to the current day. . Furthermore, in order to prevent fraudulent issuance of slips by operators themselves, various types of data management, such as management using operator-specific codes, daily inspections, settlements, time-of-day aggregations, and weekly/monthly cumulative totals, are performed on the above equipment and host machine. The management data will also be updated and changed if the slip is reissued.

In addition, with devices that are equipped with a clock circuit and read date information from this clock circuit, if the date on the clock is changed, timekeeping will continue with the changed date, which may interfere with other operations. There was a problem.

An object of the present invention is to use a simple configuration to make it possible to arbitrarily change the date information without destroying the date information generated by a date information generating means such as a clock circuit, and to easily change the changed date to the date generated above. The goal is to make it possible to convert it into information.

[Means to solve the problem]

The present invention includes a date information generation means (for example, realized by a clock circuit 8, etc.) that generates date information including year, month, day, etc., a date information memory (date memory 9, etc.), and a date information generation means. A transfer means ₍ interface ₁
0, etc.), a changing means (key input device 6, etc.) for changing the date information stored in the date information memory to arbitrary date information, and changing means (key input device 6, etc.) for changing the date information stored in the date information memory to arbitrary date information. Instruction means (preset button, etc.) for instructing the transfer means to transfer the date information generated by the information generation means.
and output means for outputting the contents of the date information memory.

[Effect]

Now, as the date information in the date information generation means, 1980
Assume that June 13, 2016 has been generated (of course, hours and minutes may be included). The transfer means transfers this date information to the date information memory upon receiving a control signal from, for example, a CPU. As a result, date information is stored in the date information memory. Here, the operator may enter arbitrary date information different from this date information, for example, April 20, 1980, for convenience such as issuing a slip.
If you want to output the date, there is no need to do anything with the date information generation means, just use the changing means to change June 13, 1980 in the date information memory to April 20, 1980. The output means outputs the contents of the date information memory by printing or displaying. Therefore, the date information can be easily changed and output without destroying the generated date information.

Moreover, if the operator outputs arbitrary date information like this, the date information memory will contain 1980.
It is no longer necessary to memorize April 20, 2017, and the date information generated by the date information generation means, that is, 1980, is no longer necessary.
It is necessary to correct the date on June 13th (or the 14th if it is set to June 14th), but the operator can simply give an instruction using the instruction means (for example, by operating a preset button, etc.), and the date information will be transferred to the date information memory using the transfer means. Since the date information is transferred, it can be fixed very easily.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings. FIG. 1 is a system configuration diagram of an embodiment in which this invention is applied to an office computer. 1 in the figure is a CPU (central processing unit), and as is well known, this CPU 1 is a device that controls the operation of the entire system, and as shown in the figure, it is a device that controls the operation of the entire system.
It is connected to internal devices such as a RAM (random access memory) 3, and external devices such as a CRT display 4, a disk memory 5, a key input device 6, and a printer 7, respectively. Note that either the Western calendar date including the current year (year, month, day, hour, minute) or the era name date including the year (Showa year, month, day, hour, minute) is stored in a part of the area 5a of the disk memory 5 by the printer 7. In order to be able to print it, at the beginning of the year, the difference value between the Western calendar and the year date of the era name, for example, in the case of 1980 AD, the last two digits of this Western calendar ``80'' and the era name 1975. The difference value "25" from the numerical value "55" of the year and date of the year is preset by a key input operation on a key input device or an external switch operation. The key input device 6 is also provided with a preset button (not shown) that is operated to preset date data of the Western calendar or era name in the date memory 9, which will be described later.

The clock circuit 8 is a circuit for obtaining the above date according to the Western calendar. Therefore, when updating the hour and minute data of the Western calendar or era name date data stored in the date memory 9 every minute, the clock circuit 8
An interrupt signal is output to the CPU 1 once per minute. At this time, the CPU 1 outputs a control signal to the interface 10, reads out only the hour and minute data of the current date data from the clock circuit 8, and causes it to be newly set in the date memory 9 via the interface 10. In addition, when presetting the date data of the era name in the date memory 9, the CPU 1 outputs a control signal and a subtraction command to the interface 10, and at this time the interface 10
Then, the above difference value "25" is subtracted from the year data "80" of the date data by Nishimaro from the clock circuit 8 to calculate the era name year data "1980", which is stored in the date memory 9. It is becoming more and more like this. Further, when the date data in the date memory 9 is changed at any time by key input operation of the key input device 6, the date data by the key input operation is changed to the interface 10.
The date is set in the date memory 9 via the . Note that the symbols Y, M, D, H, and M shown in the date memory 9 indicate the year and year of the date data, respectively.
This is a data storage section for month, day, hour, and minute.

Next, the detailed configuration of the interface 10 will be explained in the second section.
This will be explained using figures. Control signal C ₁ output from CPU 1 when presetting era name date data in date memory 9 and when updating date data every minute.
is input to each first input terminal of AND gates 11-16. Also, when presetting the above,
A control signal _C2 output from the CPU 1 is input to each second input terminal of the AND gates 11-14. Further, the difference value "25" read from the disk memory 5 is input to the third input terminal of the AND gate 11. Further, among the date data read from the clock circuit 8, the year, month, and day data are respectively input to the third input terminals of the AND gates 12, 13, and 14, and the hour and minute data are input to the third input terminals of the AND gates 12, 13, and 14, respectively. It is input to each second input terminal of AND gates 15 and 16. Therefore, the output data "25" and "80" of the AND gates 11 and 12 are respectively input to the subtraction circuit 17, but when the subtraction command is output from the CPU 1 to the subtraction circuit 17, that is, when the At the time of presetting to change the year data to the era name, the subtraction circuit 17 executes subtraction for both input data "25" and "80", and the year data "55" of the era name, that is, "1980" is calculated, and the OR gate is executed. Date memory 9 through 18
given to. On the other hand, when the year data is used without changing the Western calendar, the subtraction command is not output, and therefore "80" is given to the date memory 9 via the OR gate 18 as is. Furthermore, each output of AND gates 13 and 14,
The month and day data are given to the date memory 9 via OR gates 19 and 20, respectively, and the AND gate 1
The respective outputs 5 and 16, hour and minute data are directly given to the date memory 9. Furthermore, of the date data directly input from the key input device 6, year, month, and day data are provided to the date memory 9 via OR gates 18, 19, and 20, respectively.

Next, the operation of the above embodiment will be explained. clock circuit 8
year, which is always running and is date data according to the Western calendar.
Month, day, hour, minute, i.e., the current date is April 1980.
If it is 10:58 a.m. on the 11th, get that date data,
AND gates 12-1 in interface 10
It is given to 6. In addition, the above date data "80", "4", and "11" according to the Western calendar are normally stored in each memory section Y, M, and D in the date memory 9, respectively.
April 11, 1980 is retained. On the other hand, storage unit H,
The contents of M (hours, minutes) change as the time changes, but currently the hour and minute data "10:00 a.m." and "58 minutes" are stored in memory sections H and M, respectively, and 10:58 a.m. is memorized. When the time changes from 58 minutes to 59 minutes, an interrupt signal is output from the clock circuit 8 to the CPU 1. Therefore, the CPU 1 outputs only the control signal C ₁ and gives it to the AND gates 11 to 16, but only the AND gates 15 and 16 are opened at this time, and the clock circuit 8 sends out the hour and minute data of the date data at that time. 10 o'clock" and "59 minutes" respectively.
The data is outputted via AND gates 15 and 16 and applied to storage sections H and M of date memory 9, respectively, and new hour and minute data "10:59 a.m." is written therein.

The time/minute data update operation for April 11th described above is 1.
This is done every minute, and the date data is not updated all the time.

On the other hand, if it is desired to change the date data currently stored in the date memory 9 based on the Western calendar to date data based on the era name, the preset button on the key input device 6 is operated once. At this time, the control signals C ₁ , C ₂ and the subtraction command are sent from the CPU 1 to the interface 10.
Output for. Therefore, in the interface 10, the AND gates 11 to 14 are opened at the same time, and the AND gates 11 and 12 output data "25" and "80", respectively, and are applied to the subtraction circuit 17. Then, the subtraction circuit 17 executes subtraction on both input data "25" and "80", and obtains data "55".
is calculated and given to the storage section Y of the date memory 9. For this reason, the memory section Y contains the year data by era name "Showa 55".
"Year" is stored in memory until the next time the preset button is operated. On the other hand, the outputs of the AND gates 13 and 14 are "4" and "11", respectively, and the month/day data in the date memory 9 remains unchanged as "April 11". By operating the preset button above, the date data in the date memory was converted to the era name.
Date data based on this era name can be printed on the slip by the printer 7 or displayed on the CRT display.

Furthermore, if it is desired to change the year, month, and day data among the date data in the date memory 9 by operating keys on the key input device 6, the necessary year, month, and day data are input by operating a predetermined key. The date data entered at this time is the OR gate 1 in the interface 10.
8, 19, and 20, respectively, to storage units Y, M, and D in the date memory 9, and are stored therein. Therefore, if a printing or display operation is performed in this state, the date specified by the above key operation will be printed or displayed. Thereafter, by operating the preset button, the date data of the current day is preset into the date memory 9 by the clock circuit 8.
The preset button operates in a binary manner, and does not issue a subtraction command to the subtraction circuit 17 depending on the current operation.

In the above embodiment, the date data from the clock circuit that performs timekeeping processing based on the Western calendar can be converted to the name of the era, but this is, of course, not a limiting factor.

In addition, in the above embodiment, after the preset button is operated, the converted date data is retained until the next preset button is operated, but after the changed date data is printed or displayed, it is returned to the original year before conversion. The data may be automatically restored.

Further, in the above embodiment, this invention was applied to an office computer, but it can also be applied to various electronic devices having a printing device and a display device.

[Effect of the invention]

As explained above, according to the present invention, the date information stored in the date information memory can be changed to any date information using the changing means and outputted. It is possible to easily output any date information without destroying the date information stored in the date information, and furthermore, by simply giving an instruction using the instruction means, the contents of the changed date information memory can be easily converted into date information generated by the date information generation means. Since the date can be quickly corrected, operators can easily change the date without having to go through any troublesome work, speeding up business processing.
