JPS59149547A - 6-weekday arithmetic processor - Google Patents

Abstract

PURPOSE:To obtain six weekdays in a simple way by storing previously the data on the six weekdays in an ROM and calculating the meaning of an input date of solar calendar through an operation. CONSTITUTION:An ROM 1 stores the 6-weekday data on the 1st day of each month of the solar calendar, the relation between the 1st day of the lunar calendar and its corresponding day of the solar calendar and arithmetic processing programs of the six week days of the 1st day of the lunar calendar and the six weekdays respectively. The date to be obtained from an input part 4 is supplied in the solar calendar. Then the date is stored in an RAM 3. A central processing unit 2 decides whether the corresponding date is set before or after the 1st day of the lunar calendar. The processings to calculate the weekdays centering on the 1st day of the lunar calendar are different from each other. The codes are set opposite to each of six weekdays [a lucky day set at (0), an unlucky day set at (1), etc.], and the six weekdays of the corresponding day are calculated from the periodicity of the six weekdays.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a rokuyo arithmetic processing device for reading rokuyo such as Daian and Butsumetsu.

[Technical background of the invention and its problems]

For example, when deciding on a scheduled date for a wedding, it may be necessary to quickly find out which of the Rokuyo days, such as Taian or Butsumetsu, falls on that day.

[Purpose of the invention]

The present invention has been made in consideration of the above-mentioned circumstances, and it is an object of the present invention to provide a rokuyo arithmetic processing device that can easily satisfy the above-mentioned demands.

[Summary of the invention]

The present invention allows you to easily obtain the Rokuyo of any year, month and day (solar calendar) by memorizing the Rokuyo of each year, month, day and the first day of the month, and the Rokuyo of that day. This was done because it was better to do so.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a professional diagram showing the configuration of the same embodiment. ROM1 contains data on the Rokuyo of each month in the solar calendar, whether the first month of the lunar calendar falls on the regular day of the solar calendar, Data and the rokuyo arithmetic processing program shown in FIG. 2 are stored. CPU
(Central processing unit) 2 performs rokuyo arithmetic processing according to instructions from ROM 1. RAM 3 is switch (input section) 4
Input data from the CPU 2, calculation results from the CPU 2, etc. are stored. The input/output section 5 receives data from the input section 4' fcRAM.
,? or transfer the data of the Rokuyo calculation results to the display unit 7. The input unit 4 uses a switch or the like to request the calculation of the Rokuyo data of the year, month, and day (solar calendar). Decoder 8 decodes display data. The display section 7 displays Rokuyo. Based on the output of the oscillator 10, the frequency dividing circuit 9 divides the CPU', ? '! Send out a clock pulse to move i.

Below, according to Fig. 2, we will explain how to obtain the Rokuyo total of "January 7, 1982" as an example. First, from the input section 4 to 1
Request what Rokuyo is on January 7, 982 in RAM 3
The CPU 2 determines whether the above "7th day" is on the first day of the month. That is, according to the correspondence between the lunar calendar and the solar calendar, the first day of the month is January 25th in the solar calendar, so the result of 7<25 is "No". According to the above correspondence table, January 1st, 1982 is Akakuchi, so the code for this day is 11".
, assume that the left column is '3'', the leading negative is 14'', and Butsumetsu is 5''), and set this '1# as rokuyo data. Next, subtract 1'' from this rokuyo data < (1-1 = 0) '0' is entered in the rokuyo of the tsumashi.Next, CPU 2 subtracts '6#' from the above date 'January 7th', and if the subtraction result is negative, it adds '6' to that day. do. Here, 7-6=1
" , "1-6=-5" is negative, so '-5+6
= 1'' and set this as day data.Next, add all the day data of the above calculation result to the set value of Rokuyo and set the result as Rokuyo data.
1=1" as the Rokuyo data. Next, when comparing this Rokuyo data with '6#, we find that since the Rokuyo data is small, the above "1#=Akaguchi" is the Rokuyo data of January 7, 1982. This is displayed on the display unit 7 as day of the week data.

Next, as another example, a method for determining the Rokuyo of "January 31, 1982" will be explained. Above - as in the example '31
# is '25# in the above correspondence table, so in this case, @31-25+1=7'' is set as the day data.Next, the Rokuyo of the first day of the month (January 25th in the solar calendar) Since this day is the first win, I set all the codes ``2#'' and ``2-1''
= 1" as Rokuyo data. Next, CPU 2
is based on the data 67# of the above day, ``7-6=1'''1-
Performs the calculation 6=-5#, which is a negative value, so @-5+
The calculation result of 6=1'' is set as day data.

Next, the Rokuyo data set above “1# and day data”
1# is added, and the resulting value °°2# is set as Rokuyo data.

This data is compared with '6'' in CPU 2, and in this case, since '2# is smaller than '6', the above Rokuyo data '2#
The first win of the month is displayed as it is on the display section 7 as the Rokuyo of January 31, 1982.

As mentioned above, the Rokuyo data of each month in the solar calendar,
If you memorize what day in the solar calendar the first day of the month falls on and its six days of the year, you can do it without having to memorize a huge correspondence table between each day of each year and month of the solar calendar and its six days of the year. The processing program shown in FIG. 2 is used to obtain the Rokuyo of a desired date in the solar calendar.

〔Effect of the invention〕

As explained above, according to the present invention, the Rokuyo of a desired year, month, and day in the solar calendar can be found by simply remembering the Rokuyo and the first day of each month of each year and their Rokuyo. , it is possible to provide a rokuyo arithmetic processing device with a simplified configuration.
