Abstract

PURPOSE:To make it unnecessary to provide with a data controller for exclusive use, by changing optionally the sequence of expression of year, month, and day of date data. CONSTITUTION:If a switch B-1 constituting a specification changeover switch 7 is turned on when the print of the date is instructed by a function key of a keyboard 4, day data is set in buffer memories PB7 and PB8 of a print buffer 8, and month data is set in buffer memories PB4 and PB5, and year data is set in buffer memories PB1 and PB2. Next, when the print command of a CPU1 is applied to a controller 9, data of the buffer 8 are sent to a printer 10 and are printed in the order of the day, the month, and the year. Meanwhile, if a switch B-2 is turned on, month data is set in memories PB7 and PB8, and day data is set in memories PB4 and PB5, and year data is set in memories PB1 and PB2, and date data is set in the order of the month, the day, and the year.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a date control device that obtains date data of the year, month, and day using a timekeeping means and controls the data to be printed or displayed.

The above-mentioned date control device is installed in, for example, an electronic desktop calculator or a cash register and used for date management, etc., but conventional devices of this type do not print or display date data such as year, month, and day. Since the order is fixed, there are the following drawbacks.

In other words, even though in Japan it is normal to express the year d, month, day, in Europe it is expressed as day, month, year, and in the United States it is expressed as month, day, day.
It is common to express them in chronological order.

In this way, dates are expressed differently in each country.
In addition, since it has become a habit to express dates in this way, conventional devices in which the order of date expression is fixed are not versatile at all. Equipment had to be prepared.

In view of these conventional drawbacks, the present invention provides a date control device that can arbitrarily change the order of representation of year, month, and day as date data. An embodiment of the inventive device will be described in detail.

FIG. 1 is a block diagram of an electronic device equipped with the device of the present invention. In the figure, 1 is the central processing unit (CPU), 2 is the CPU
A control memory (ROM) stores a program for controlling the I, and a data memory (RAM) 8 temporarily stores data for controlling the program.

4 is a keyboard that is equipped with a numeric keypad and function keys that can input numerical values or perform special tasks on the CPUI, and is connected so that these key signals can be transferred to the CPU 1 via the key controller 5; 6 is a device mode; The mode selector switch (MODESW)
), 7 is a specification changeover switch (SW-B) for changing the device specifications, i.e., the printing or display order of year, month, and date.
), and consists of two switches B-1 and B-2.

8 is equipped with a buffer memory of PBI to PBIO, and
Print buffer that stores print data from the UI, 9
is a printer controller that controls the transfer of print data in the print buffer 8 to the printer 10 for printing under the control of the CPUI.

On the other hand, 11 is equipped with a DBI-DBIO buffer memory and stores display data sent from the CPU 1, and 12 is a display buffer that transfers the display data in the display buffer to the display unit 13 under the control of the CPU 1. The display controller 14 calculates and automatically updates the date based on the reference oscillation signal f, and outputs two-digit data each for the year, month, and day (the year data is the last two digits of the Western calendar) to the CPUI. This is a date data output device.

Next, the operation will be explained in detail based on the flowchart shown in FIG.

First, in accordance with the input of a function key instructing date printing on the keyboard 4, the on/off state of switch B-1 constituting the specification changeover switch 7 is determined (judge J1). If the result of the determination is that it is on, the date data (2 digits) is set to PB8 in step A1, and the date data (2 digits) is set in buffer memory PB4 in step A2.
and set it in PB5, and enter the year data (2 digits) in step A3.
Set ノ(in sofa memory FBI and PB2).

In this way, when the date data is stored in the buffer memory in the form of day, month, and year, the program proceeds to step A and prints a dot "." in buffer 1 memory PB8 and PB6 to distinguish the date data. Data is set, and blank data is further set in the buffer memories PB9 and PBIO in step A5.

Here, each buffer 7 memo IJPBI to PBIO corresponds to a printing digit, and therefore, the CP is now sent to the controller 9.
When the print command U1 is applied, the data in the print buffer 18 is sent to the printer 10 and printed in the order of day, month, and year.

On the other hand, if the judge J1 determines that the B-1 switch constituting the specification changeover switch is off, the judge J2 further determines whether the B-2 switch is on or off. Here, if the B-2 switch is on, proceed to step B1 and transfer the monthly data to the buffer memory IJ.
Set the day data to PB7 and PB8, and set the day data to 7 (sofa memory PB4 and PB5 in step B2,
Furthermore, in step B3, buffer 1 memo IJ of year data
Set to P B 1 and FB2. Then, as described above, the process proceeds to step A6 via steps A and A, and the date data in these five cases is printed in the order of month, day, and year.

Furthermore, if the B-2 switch is in the OFF state as determined by the judge J2, the flow advances to step C. That is, in step C1, year data is first set in sofa memories PB7 and PB8, proceeding to step C2, month data is set in buffer memories PB4 and PB5, and furthermore, in step C3, day data is set in buffer memories FBI and PB2.
Set to . After that, step A4A3. Proceed to A6,
Printed in the order of year, month, and day. The above operations can be summarized as shown in the table below.

Note that the display buffer 11 includes a print buffer 7.
Since it is structured so that the same content as the data entered in 8 is entered, the date data can be displayed in exactly the same order as in the case of printing.

In the above embodiment, the state of the specification changeover switch 7 is determined to change the printing or display order of the year, month, and day of the date data. The printing or display order of date data may be changed by storing the year, month, day and their order in the memory 8 as numerical data.

As described above, in the device of the present invention, the printing or display order of date data (year, month, and day) can be changed arbitrarily, so a number of dedicated date control devices can be installed according to the specifications. This has the great effect of eliminating the need for preparation.
