Description

[Detailed Description of the Invention] This invention relates to a calendar printing device for creating a calendar in a small electronic device equipped with a printing function, such as an electronic desktop calculator with a printer.

Generally, in an electronic desktop calculator with a printer equipped with a calendar creation function, each time a calendar for a desired specified period is created, date information necessary for the calendar to be created is inputted by complicated key operations.

By the way, there are many cases where you want to create a calendar for a specified period that corresponds to the current date information, such as a calendar for the current month, but each time you do this, you have to enter the current date information using keystrokes. However, this type of input operation has the disadvantage of being cumbersome.

This invention was made based on the above circumstances, and its purpose is to obtain and print calendar information for a specific period based on date information from a clock circuit, so that it corresponds to the current date information. A calendar for a specific period can be created by simple operation of a specific key.
Therefore, it is an object of the present invention to provide a calendar printing device that simplifies key operations.

An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

Figure 1 shows a schematic diagram of the country in which an embodiment of this invention is applied to an electronic desk calculator with a printer. It is provided with a numeric keypad 2 used for input, and function keys consisting of a decimal point key 3, a multiplication key 3□, a division key 33, a minus key 34, a plus key 35, and an equal key 36, and furthermore, it is provided with function keys for inputting date information. A date (DATE) key 4 used when issuing a calendar, and a calendar (CALE) key 5 used when issuing a calendar are provided.

The input section 1 is supplied with a sampling timing signal KP from a CPU (central processing unit) 6, and when a key is operated in the input section 1, the timing signal KP is selected according to the operation key, and the timing signal KP is selected according to the operation key. It is given to the CPU 5 as a signal Kl.

The CPU 6 includes a control unit, arithmetic unit, etc. that store various microinstructions, an X register that stores the year, month, and date data input through the input unit 1, and various types of registers used for printing, display, and transfer. A register is provided.

A print control section 7 and a clock circuit 8 are connected to the CPU 6, and the print control section 7 is selected by a control signal OP outputted from the CPU 6, and a print buffer provided in the print control section 7 is selected. Print data PD is output from the CPU 6 and written.

Further, the clock circuit 8 measures date information such as current year information and month information, and sends it to an M register provided therein for storage.

The clock circuit 8 receives an address designation signal from the CPU 6 via the address bus line AB, and exchanges data with the CPU 6 via the data bus line DB.

The printing control section 7 is connected to the printing section 9, and the printing section 9 sends a printing position signal TP of a printing drum (not shown) provided therein to the printing section 9, and also connects the printing section 9 to the printing section 9. 7 internally sends to the printing section 9 a print drive signal MD generated by the coincidence between the print position signal TP and the print data PD in the print buffer.

Then, the printing section 9 performs a printing operation when a predetermined hammer is driven according to this printing drive signal (2),
Calendar information and the like are printed out on recording paper 10.

Next, the operation of the electronic desk calculator with printer configured as described above will be explained.

When creating a calendar for August 197, which indicates the current year and month, when the calendar key 5 is operated, the operations shown in the flowchart of FIG. 2 are performed.

First, in the execution of step S1, whether or not the content stored in the X register in the CPU 6 is rOJ, in other words, whether or not a key operation for inputting date data was performed immediately before operating the calendar key 5. If the determination is YES, step S2 is executed, and if the determination is NO, step S3 is executed.

In this case, the calendar key 5 is operated without inputting date data, so the answer is YES and the process moves to step S2.

In executing step S2, an address designation signal is applied from the CPU 6 to the clock circuit 8 via the address bus line oil to designate the address of the M register.

Then, date data consisting of current year data and month data stored in the M register is read out and written to the X register in the CPUG via the data bus line DB.

Next, step S3 is executed, and the CPU 6 outputs the control signal OP to select the print control section 7.
Date data stored in the X register is read out and given to the print buffer.

Then, a print drive signal M based on the contents of the print buffer
D is applied to the printing unit 9, a predetermined hammer is driven, date information '1979-8J shown in FIG. 1 is printed on the recording paper 10, and the paper is then fed by one line.

Next, step S is executed, and in the CPU 6,
Based on the date data stored in the register, it is determined whether the month is a large or small month, or whether the year is a leap year, and as a result, the last day of the month is calculated. .

Furthermore, the day of the week of the first day of the month is calculated based on the date data, and although the details of this calculation method are omitted, the number of days from the hypothetical base date to the desired date is calculated, and this calculated number of days is calculated. This is done by correcting 1+IJ and then dividing by 17yo to find the remainder.

In this case, the 31st is calculated as the last day of the month, and Wednesday is calculated as the 1st day of the week.

Next, step S5 is executed, and one week's worth of calendar information is sent to the print buffer based on the day of the week.
It is printed by the printing section 9.

After printing is completed, the next week's calendar information is sent to the print buffer.

Thereafter, the calendar information obtained in step S4 is printed on a weekly basis until the end of the month.

As a result, the calendar for August 1, '197 is printed on the recording paper 10, and thereafter, the paper is fed by a predetermined amount, and the calendar creation operation in this case is completed.

By the way, if you want to create a calendar for a month different from the current year and month, for example, a calendar for June 1, 2019, use the numeric keypad 11, (9), (2), old 1, date key 4, and numeric keypad 6. , date key 4 are operated in sequence, this operation signal is given to the CPU 6 as a key manual signal Kl and written into the X register.

Next, when the calendar key 5 is operated, step S1 is executed. In this case, it is determined that the contents of the X register are not rOJ, and then the process moves to step S3, in which the date data stored in the ,
Printed on recording paper.

Next, step S1. S5 is executed, and as a result, a calendar of ``197CR-, June'' is printed on the recording paper.

In the above embodiment, a case has been described in which a monthly calendar is created, but the present invention is not limited to this. For example, a calendar can be created in units of arbitrary periods, such as creating a weekly calendar. It's okay.

Further, in the above embodiment, the case where this invention is applied to an electronic desktop calculator with a printer has been described, but it is not limited to this, and can be applied to other small electronic calculators equipped with a printing function. .

According to this invention, in a small electronic device such as an electronic desktop calculator with a printer, a calendar table for any month can be printed extremely easily on a recording paper provided in the main body of the device.

In addition, the present invention includes a clock circuit that measures and stores current date information, a determination means that determines whether or not date information has been input before a specific key is operated, and, if date information has been input, the date information. , and in the case of no date information input, calculation means for calculating calendar information within a specific period based on the date information stored in the clock circuit. A calendar table can be printed very easily with only one operation, and a calendar table for any month can be printed out simply by inputting the desired month and operating the above-mentioned specific keys.
