Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic computer that executes a predetermined notification operation when power is supplied.

Electronic computers, so-called office computers, are used for payroll calculations, year-end adjustment calculations, billing, etc.
Processes that have a predetermined execution date are often performed. Therefore, before starting computer operation every morning, operators currently check a schedule, calendar, etc. to determine the programs to be processed that day. This confirmation work was extremely troublesome, and I sometimes forgot it.

On the other hand, recently, electronic computers equipped with a clock device have been developed for purposes such as displaying the time on a CRT screen, omitting the date preset that is performed every morning before starting operations, or printing time stamps on slips. Therefore, in order to solve the above-mentioned problems, it is possible to provide this clock device with an alarm function, but since electronic computers, which are generally called office computers, shut off the power at the end of each day's work, it is difficult to detect the alarm time. At times, if the power to the computer was cut off, the notification operation could not be executed.

This invention was made in view of the above circumstances,
Power is supplied as needed at the start and end of work, etc.
It is an object of the present invention to provide a computer that is shut off and performs a predetermined notification operation such as automatically displaying a comment of a program to be processed on that day when power is supplied.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. In the figure, 11 is the central processing unit (CPU)
), and power is supplied/cut off by a power switch (not shown). This CRU1
1 is connected to a keyboard 12, a CRT display device 13, and a magnetic disk storage device 14. This magnetic disk 14 stores comments 141 regarding programs to be processed in the future. Examples of comments are program name, file
No., business code, etc. can be considered.

Reference numeral 15 denotes a clock device equipped with an internal power supply 151, a clock circuit 152 that keeps time at all times and creates current date and time data consisting of year, month, day, hour, minute, and second, and a clock circuit 152 that measures the current time and creates current date and time data consisting of year, month, day, hour, minute, and second. A date memory 153 that presets the date of execution of the program to be processed, and the date data preset in this date memory 153 and the clock circuit 15
2, and a comparison circuit 155 which sets a flip-flop 154 when a match is detected. The set output of the flip-flop 154 is sent to the CPU 11 as an interrupt signal A, and when the power of the CPU 11 is turned on, a predetermined notification process is executed. Then, upon completion of the notification process,
A reset signal B is output from the CPU 11 to reset the flip-flop 154.

Next, the operation of the computer configured as described above will be explained. First, if there are several programs that must be processed in the future, a comment (program name, etc.) and the date of execution of the programs are created in the magnetic disk 14. Next, the date of execution of each program is input from the keyboard 12. Through this input operation, a plurality of years, months, and days are stored in the date memory 153 within the clock device 15.

Since the clock device 15 is constantly supplied with power by the internal power supply 151, it operates even when the power to the CPU 11 is cut off, and the clock circuit 15 is constantly supplied with power.
Current date data and date memory 153 created by 2
A comparator circuit 155 compares the date data stored in the date data. When the two dates match, the comparison circuit 155 outputs a match detection signal and sets the flip-flop 154. The set output of the flip-flop 154 is sent to the CPU 11 as an interrupt signal A, but since the dates usually match at 12 o'clock in the morning, the power to the CPU 11 is cut off, and the CPU 11 does not accept this interrupt signal A.

When the CPU 11 is powered on in the morning, the flip-flop 154 remains in the set state, so the CPU 11 detects the interrupt signal A. This interrupt causes the CPU 11 to execute a comment display program. That is, the comment 141 of each program is read from the magnetic disk 14, the date stored with the comment is checked, and the comment of the program to be executed on that day is sent to the CRT display unit 13 for display.

Therefore, when the power is turned on to the CPU 11 at the start of work in the morning, the comments of the programs to be executed that day are automatically displayed on the CRT screen.

Note that in the above embodiment, the comment of the program to be executed on the day is displayed when the CPU is powered on, but the present invention is not limited to this, and an alarm sound may be generated to indicate that there is a program that must be processed on the day. There are various possibilities, such as displaying a warning on the CRT screen.

Further, in the above embodiment, the year, month, and day are set as the execution date of the execution program, but it is also possible to set only the month and day, or to include information on the day of the week.

As explained above, according to the present invention, the detection signal of the match/mismatch between the data created by the timekeeping circuit and the arbitrarily set and stored date data is temporarily held, and the held content is updated when power is supplied. Depending on the situation, predetermined notification operations (for example, displaying comments for programs to be executed on the day, generating alarm sounds, displaying warnings, etc.)
Since the program is executed, the operator is freed from the troublesome task of checking the program to be processed that day from the schedule every morning, and can also prevent mistakes such as forgetting to execute the program.
