Abstract

PURPOSE:To make a perpetual calendar usable in any calendar month by displaying seven groups of numerals or numerals, characters, symbols, etc., equable to the seven groups of numerals by coloring them in seven different colors or together with the colors in a calendar day display section. CONSTITUTION:The color of a day-of-the-week frame 32 in a day-of-the-week display section 14 is made the same as that of the row of a calendar day display section, to which the same numeral as the numeral after hyphen of the frame 32 belongs. When, for example, it is required to know what day of the week is the 13th February, 1989, the calendar day display column 282 having a calendar year index column 30 described as '1989' is first checked in the calendar day display section 14 and it is found that the first Sunday of February, 1989 is the 5th February. Since the day-of-the-week frame 32 of this February, 1989, is green, it is known that the 12th February, 1989 is Sunday from the group of green-colored numerals '5, 12, 19, and 26'. Therefore, it can be found that the 13th February, 1989, in question is Monday.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a perpetual calendar that can be used in any calendar month.

[Prior Art] A perpetual calendar has a calendar day display section consisting of 31 numbers "1 to 31" indicating consecutive calendar days from the 1st to the 31st belonging to one month.

The most common form of such a perpetual calendar is to use these 31 numbers as "1-7", "8-144 r15-
214 r22-28J r29-31" is displayed in five lines. In addition, the present inventor previously provided 31 consecutive numbers "1 to 31" in Japanese Patent Application No. 62-328098 and the patent application dated February 10, 1986, as three rows of numbers. There is a calendar that is divided into four rows of numbers, and the numbers in the two adjacent rows are arranged differently (this second type of perpetual calendar will be explained in more detail later).

In any calendar, it would be convenient if groups of numbers indicating calendar days that are offset by one hour could be easily recognized together. Let me explain this.

Such a group of numbers is “1, 8, 15, 22.29J
group, r2.9.16, 23.30J group, r3.10
．． 17, 24, 31'' group, r4, 11, 18, 25J
group of r5,12°19.26J, r6.13,2
0.27J group, and "7, 14, 21.28J group,
There are seven groups. If the numbers in each group are collectively recognized as belonging to each group, for example, if a calendar user indicates that the first day of a certain month is Sunday, it will be recognized as "1° 8.15". You can immediately know that the calendar days indicated by .22.29J all correspond to Sundays.

Also, for example, the group of numbers ``1, 8, 15.22.29J and the group r2.9, 16.23, 30J can be easily recognized as being in different groups, so ``1, 8.15.22 ．．
r2.9,16 when you know that the group of digits 29J indicates a calendar day in the column that corresponds to Sunday, for example.
．． It can be immediately seen that the group of numbers 23.30J indicates a calendar day corresponding to Tuesday.

[Problem to be solved by the invention] The problem to be solved by the invention is to solve the problem in the above-mentioned perpetual calendar.
1, 8.15, 22, 29J numbers, r2.9.16.
23, 30J numbers, ``3゜10.17, 24.31J
number, r4,11゜18.25J number, r5,12
, 19, 26J, r6, 1B, 20.27J, and r7.14, 21.28J, respectively, to provide a calendar that can be recognized as a group.

[Means for Solving the Problems] The above problems are solved by the configuration described in the characterizing part of claim 1.

In addition, in the present invention, "numbers, characters, symbols, etc." that indicate a calendar year, calendar month, or calendar day are "1, 2, etc."
Arabic numerals such as ``...'', rI, II...
Roman numerals such as ``-12...'', Chinese numerals such as ``-12...'', and other numbers such as ``1st'' and ``Tsutachi J r
It broadly refers to characters such as "First day J," or Japanese and foreign characters, symbols, and other items with equivalent meanings.

Furthermore, in the present invention, the term "color" refers to all chromatic colors, achromatic colors, metallic colors such as gold and silver, transparent/semi-transparent colors, and anything that can be visually discerned.

[Function] Since the numbers of the seven groups described above are associated with each of the seven different colors, the numbers of each group can be easily recognized as a group.

[Embodiment] In the embodiment shown in FIGS. 1 and 2, IO indicates the entire perpetual calendar of the present application, and this perpetual calendar IO consists of a calendar day display section 12 and a day of the week display section 14. . For simplicity, the day of the week display section 14 is shown only by a dashed-dotted frame line in FIG. 1, and details are shown in FIG. 2.

In the calendar day display section 12, the numbers "1 to 28" are displayed as 7
Divide each number into four horizontal lines and write them sequentially. In other words, the first line contains the numbers "1 to 7" and the second line contains the numbers "8".
-14'', the third line has numbers 15-21, and the fourth line has numbers 22-28. Furthermore, in the fifth line, numbers "29 to 31" are written.

Each of these numbers is printed in black within another circular area 1B colored in the respective color. This other circular area IB is shown only by a circular outline in the figure for simplicity.

31 each containing 31 numbers from "1 to 31" inside
The colors of the other circular areas IB are different for each of the seven groups into which these numbers are divided. In the illustrated embodiment, "1, 8.15.22, 29" belonging to the leftmost vertical column
The other circular area 16 containing the number J is colored red.

Similarly, r2,9, belonging to the second vertical column from the left,
The other circular area 16 containing the numbers 16.23.30J is
r3.1 colored in navy blue and belonging to the third vertical row from the left
Other circular area 1B containing the numbers 0.17.24.31
is colored yellow and belongs to the fourth vertical column r4,11
．． The other circular area 16 containing the number 18.25J is colored sky blue and contains the number “5°12.19” belonging to the fifth vertical column.
, 26J are colored green, and belong to the 6th vertical column r6, 1B, 20, 27J.
The other circular area 1B containing the numbers is colored pink,
r7.14.21.28 belonging to the rightmost vertical column
The other circular area 16 containing the number 4 is colored purple.

In each other area 16, the numbers such as rlJ r2J may be colored black or the like, or may be outlined.

In the figure, "red -", "navy →", etc. are displayed, but these are not displays that form part of the calendar of the present invention.
It is for explanation of the figure.

These displays indicate that all other circular areas belonging to the vertical column to which the display is attached are colored in the color.

In addition to this embodiment, there are various methods of color-coding the numbers belonging to the above seven groups into seven different colors in the calendar date display section.

7 to 11 show examples of changes in this respect.

In addition, although characters such as "red" and "navy blue" or these characters and arrows are shown in the figures in these figures, this is for the purpose of explanation and does not apply to the calendar of the present application. It is not an indication that it forms a part.

In FIG. 7, "1, 8, 15.22.
Bars 17 of the same color (red in this embodiment) are arranged between the numbers 29J. Similarly, the second
Another bar 17 of the same color (in this example, navy blue) is arranged between the numbers r2.9.16.23, 30J of the third group, and r3, 10.17 of the third group. , 24.31J, there are other numbers of the same color (in this example,
A yellow) bar 17 is arranged. Although not shown, bars 17 of different colors are similarly arranged between the numbers in the fourth to seventh groups.

In FIG. 8, "1, 8.15.22.
The number 29J is placed in the same color (in this example, red) frame 1.
8 and belongs to the second group r2.9.16,2
The number 3.30J is surrounded by another frame 18 of the same color (in this example, navy blue) and belongs to the third group r3.10.
, 17°24.31J are each further surrounded by another frame 18 of the same color (yellow in this example). Although not shown, r4.1 belongs to the fourth column from the left.
Numbers 1, 18, 25J, 5th column r5.12.19
．． Number 26J, 6th column r6, 13, 20, 27J
The numbers 7, 14, and 21.28J in the rightmost column are also surrounded by frames 18 of different colors.

In Figure 8 above, each number in each group is individually surrounded by a frame, but instead, as shown in Figure 9, all the numbers belonging to each group are surrounded by a single elongated rectangle. frame 20
It may be surrounded by

In this case as well, the color of the frame 20 is different for each group. In the illustrated embodiment, the numbers belonging to the leftmost vertical column are surrounded by a red frame, the numbers belonging to the next vertical column are surrounded by a dark blue frame, and the numbers in the third vertical column are surrounded by a yellow frame. ing.

In the above modification example, the 31 numbers "1 to 31" in the calendar day display section are printed entirely in the same color, such as black,
Other areas surrounding the number 16, frame 1g, 20. Alternatively, although the bar 17 is shown colored in seven different colors, instead of this, as shown in FIG. 10, the numbers themselves belonging to each group may be printed in different colors.

In the modified example of FIG. 11, the calendar 10 includes a lower sheet 22 having a calendar date display section, and a transparent upper sheet 24 that is hingedly connected at one side of the lower sheet 22.
The upper sheet 24 is provided with a plurality of band areas 26 colored in different colors.
2.24, one of the seven groups of numbers displayed on the lower sheet 22, for example, r7.14.2.
One band area 26 (for example, the purple one at the left end) overlaps one band area 26 (for example, the purple one at the left end), and the numbers in that group are colored in that color and can be visually observed.

The other area 16 may have any shape such as an oval, a square, a rectangle, a triangle, a rhombus, a hexagon, or the like.

This also applies to frame 18. Also,
The frame 20 and the band region 2B may be oval or other shapes.

The bar 17 in FIG. 7 may be an interrupted line or a curved line.

The method of coloring each of the seven groups of numbers is not limited to the above, and any method may be used. In short, it is sufficient that the viewer can immediately understand the relationship between each group of numbers and each color. In the characteristic part of the claims, it is stipulated that "the numerals in seven groups are displayed in seven different colors or together with these colors", but this does not mean " The 31 numbers themselves from 1 to 31 are printed in seven different colors,
The idea is that the numbers themselves are all printed in one color (eg, black), with all cases where each group of numbers is associated in some way with a particular color.

Note that the specific hues of the seven colors are not limited to those in this example.

In the embodiment of FIG. 1, for example, "4 days"
A small number "5" is shown above the number "4". This indicates that May 4th is a national holiday. Similarly, two small numbers "9" and "11" are shown above the number "23" indicating that it is the 23rd. This indicates that September 23rd and November 23rd are both national holidays.

As described above, in this embodiment, the number of the month of the calendar month in which a specific calendar day is a holiday is shown in small letters near the number indicating the calendar day. This makes it possible to immediately know all the calendar months and calendar days of public holidays during the year.

Some numbers are marked with an asterisk (*) next to the number above the number indicating the calendar month. For example, "*3" above "20". This indicates that although March 20th is the vernal equinox, the vernal equinox may fall on a different calendar day depending on the year.

In the embodiment shown in FIG. 1, in order to indicate that a specific calendar day is a holiday in a certain calendar month, the number representing the month is displayed in small size above the number representing the calendar day. In short, all manners of use that can be distinguished from numbers representing adjacent calendar days, such as displaying the number representing the month in a larger size, using a different font, or displaying it in a different color, fall within the scope of this invention. . Further, the display position may be in the vicinity of the number representing the calendar day, and it does not matter whether it is above, below, to the left or to the right.

In the calendar date display section 12, "1" and "2" representing the calendar day are displayed.
Instead of arithmetic numerals such as rlJ rIIJ, Roman numerals such as "-" and "two" may be used, and
roneJ rtwoJ or “firstJ
Characters such as rsecondJ may also be used. In short, a wide range of numbers, letters, symbols, and other symbols that are objectively recognized as indicating calendar days may be used.

Although not shown, instead of the calendar date display section in Figure 1,
〜7'' ``8〜14J r15〜21'' ``22〜28
A row of seven numbers "Jr29-31" may be arranged in the vertical direction. In this case, "1, 8, 15.22.2
Groups of numbers such as 9J are arranged horizontally. In other words,
Rows of numbers colored in the same color extend horizontally.

Next, the calendar date display section 14 will be explained with reference to FIG. In this figure as well, characters such as ``yellow'' and ``purple j'' are for explanation purposes only and are not part of the calendar.

As described above, in this embodiment, seven different colors are given to the seven rows of numbers in the vertical direction, and these seven rows can be clearly distinguished and recognized by these colors. Therefore, the numbers in the leftmost column all indicate calendar days that correspond to the same day of the week (e.g., Sunday), and the numbers in the second column from the left all correspond to the next day of the week (e.g., Monday). Easily recognized as indicating a calendar day. Therefore, when using this perpetual calendar, for example, if you know that the first day of a certain month is Sunday, you can use "1, 8.15,
Since 22 and 29J are colored the same color but different from the other groups, it can be quickly and easily determined that the 8th, 15th, 22nd, and 29th also correspond to Sundays. . Also, r2,9°16.23,30J adjacent to this
Since the numbers are colored in different colors, it can be easily and quickly determined that the calendar day indicated by these numbers corresponds to the next day of the week, that is, Monday.

In the calendar date display section 14 of FIG. 2, small rectangular portions are arranged in 7 rows and 13 columns. Each row is called a day of the week display column 28.

In each day of the week display field 28, there is a calendar year heading field 30 at the left end. This has numbers indicating the calendar year inside a rectangular frame. For example, "1988" is written in the calendar year heading field 30 of the day of the week display field 28□ on the first line, indicating that this day of the week display field 28□ relates to 1988.

Similarly, the day of the week display field 28□ on the second line was set in 1989, the day of the week display field 283 on the third line was set in 1990, and the fourth
The day of the week display field 284 on the fifth line was created in 1991, the day of the week display field 285 on the fifth row was created in 1992, and the day of the week display field 28 on the sixth row was created in 1992. is for the year 1993, and the day of the week display column 28□ on the seventh line is for the year 1994.

In each of the day of the week display fields 281 to 287, twelve rectangular day of the week frames 32 are displayed on the right side of the calendar day heading field 30 and adjacent thereto.

Each day of the week frame 32 is a rectangular colored area 3.
4 is displayed by connecting two numbers with a hyphen, such as rl-34.

To explain the day of the week frame 32 belonging to the day of the week display column 281 on the first line, each day of the week frame from the leftmost day of the week frame to the rightmost day of the week frame has “1-3J r2-7J
r3-6J r4-3J r5-IJ r6-
5J r7-3J r8-7J r9-4Jrl
It is displayed as o-2J rll-6J rl2-4J.

In the display of each day of the week frame 32, the first number, that is, the number before the hyphen, indicates the calendar month to which each day of the week frame 32 corresponds. In other words, if "1-3" is displayed,
The display of r2-7J indicates that it is a day of the week frame for January, and the display of r2-7J indicates that it is a day of the week frame for February.

Among the displays in each day of the week frame 32, the last number, that is, the number after the hyphen, indicates the calendar day corresponding to the first Sunday in the calendar month to which the day of the week frame belongs. For example, the leftmost day of the week frame 32 of the day of the week display column 28 in 1988
is displayed as rl-3J, which indicates that the first Sunday of January of this year is the 3rd. In the day of the week frame 18 to the right, r2-7J is displayed, indicating that the first Sunday of February of this year is the 7th.

Regarding the day of the week display column 281 in the first line, the third r3-6J indicates that the first Sunday in March is the 6th, and the fourth "4-3" indicates that the first Sunday in March is the 6th. The first Sunday of May is the 3rd, and the fifth r5-IJ is the first Sunday of May.
The 6th r6-5J means that Sunday is the 1st, and the 7th "7-3" means that the first Sunday in June is the 5th.
means that the first Sunday in July is the 3rd, and the 8th r8
-7J means that the first Sunday of August is the 7th, and the 9th r9-4J means that the first Sunday of September is the 4th.
The 10th "10-2" means that the first Sunday in October is the 2nd, and the 11th rll-6J means that the first Sunday in November is the 6th. 4” is 1
This indicates that the first Sunday of February is the 4th.

Each day of the week frame is colored differently, and the color is determined as follows. In other words, the leftmost day of the week frame 32 in the day of the week display column 28□ for 1988 on the first line has rl
-34 is displayed, and at the same time this frame is colored yellow.The reason is that "
This is because the number "3" is colored yellow in the calendar date display section of FIG.

In other words, rl-3J means that the first Sunday in January is January 3rd, but in Figure 1, the number "3" representing the 3rd and the calendar days that differ by 3rd and 7 days are shown. (i.e. calendar days that fall on the same day of the week as the 3rd), the 10th, 17th, 24th,
A row of numbers (in the illustrated example, the third vertical row from the left) consisting of the numbers rlo indicating the 31st and 17.24.31J is colored yellow.

With this structure, when you look at the calendar date display section and find out that the first Sunday of January 1988 is January 3rd from the entry in the day of the week display field 28□ on the fth line, If you look at the part in the calendar date display that is colored the same as the yellow color of the day of the week frame where the 3rd is written, that part will be 1
It corresponds to the number indicating the calendar day that falls on a Sunday in January 988. In this way, by comparing the colors and with the help of the colors, it is easy to determine that the calendar days corresponding to Sundays in January are the 3rd, 10th, 17th, 24th, and 31st. You can know it instantly.

Since the display of r2-7J to the right of the display of rl-3J is purple, look for the purple part in FIG. In Figure 1, the purple parts are “7, 14.21, 2” belonging to the rightmost column.
8J, and from this we immediately know that the calendar day corresponding to the first Sunday in February 1988 is February 7th, and the following Sundays are the 14th, 21st, and 28th. You can know.

In this way, in the present invention, each day of the week frame 32 in the day of the week display section 14 is colored in the same color as the column to which the same number as the number after the hyphen in the day of the week frame 32 belongs in the calendar day display section. has been done.

A detailed explanation of how to use the calendar of this embodiment is as follows.

For example, suppose you want to know what day of the week February 13, 1989 is.

First, in the day of the week display section 14, look at the day of the week display field 282 that has the calendar year heading field 30 written as r1989J, and then look at the second day of the week frame among the 12 day of the week frames 32 adjacent to this field, and look at the day of the week column 282 that has the calendar year heading field 30 written as r1989J. We know that the first Sunday of the month is February 5th.

Here, since the color of the day of the week frame 32 for February is green, r5.12 is colored green in the calendar day display section 10.
．． From the group of numbers 19.26J, we can easily know that February 12th is a Sunday. And finally, I want to know February 1
Since the 3rd is the day after February 12th, we can know that February 13th is a Monday.

Also, suppose you want to know what day the third Tuesday of March in 1990 is.

First, in the same way as above, look at the day of the week column for 1990 and find that r3-4J is written in the third day of the week frame. Since it is known from r3-4J that March 4th is the first Sunday in March, the user searches the calendar day display section 12 for the same color as the sky blue of this day of the week frame. r4, 11.18.
Since the number ``25'' is displayed in that sky blue color, we know from this that the third Sunday of this month is the 18th.

Finally, you can find out that the third Tuesday of the month you want to know is the 20th, which is the day after the 18th.

The day of the week pieces 32 may be arranged vertically instead of horizontally. Furthermore, the 12 day of the week frames for each calendar year may be arranged in two rows.

Displays in the calendar year heading column 28 include, in addition to those shown in the figure, r1988J r88J r' 88J "88
``-9 to 9 J rlIX■■'' ``Showa 63
Any display that makes it easy to understand the calendar year may be used.

Also, the display in the day frame 32 is "January 3rd" and "January 3Jr13Jrl/3J" instead of rl-3J etc.
rl: 3J r■3J rl 3J, etc., or by using different colors for "1" and "3", the key is to clearly distinguish and recognize the characters indicating the calendar month and the letters indicating the calendar day. It's fine as long as it's possible.

Also, rJan to represent a calendar month and calendar day.

Words such as IJ rJanuary 1stJ may also be used.

Also, the method of coloring each day of the week frame 32 is also different from the day of the week display section 1.
As in the case of the number 2, you can fill the rectangular area with each color and write a number such as "rl-3" on top of it. Alternatively, the frame of the day of the week frame 32 can be painted in red, etc. It is also possible to omit such a frame line and use the color r.
The numbers themselves, such as l-3j, may be colored, or all the numbers may be printed in black, and the hyphens between the numbers may be displayed in the color assigned to each day of the week frame. In short, frame 3 for each day of the week
2 may be associated with a specific color. Further, when the outer shape of the day of the week frame 32 is drawn by a frame line, the frame line may be a circle, a diamond, a triangle, or any other arbitrary shape in addition to a rectangle.

In this embodiment, the day of the week display section 14 displays the first Sunday of each month. However, instead of this, the second Sunday, the third Sunday, and the fourth Sunday may be displayed, or the specific number of days of the week other than Sunday (e.g., Monday, Tuesday, etc.) (e.g., the second Monday) may be displayed. In short, in each calendar year, a specific day of the week (for example, Sunday) of the same number (for example, the first day) throughout each calendar month may be displayed.

3 and 4 are examples of changes in the arrangement of 31 numbers indicating "1st to 31st" in the calendar date display section 12, respectively. In this case, the day of the week display section 14 is the same as that shown in FIG.

The details and operation of the calendar date display section 12 shown in FIGS. 3 and 4 are described in U.S. Pat.
Please refer to the specification of No. 176578. In the following, we will only briefly describe the configuration.

In the embodiment shown in FIG. 3, the calendar date display section 12 is configured as follows. In the first vertical column, that is, the leftmost column, the numbers "1, 2°3" are arranged, and in the second vertical column, r4.5.6,7J.
Each number is arranged differently. In other words, "4
” is placed above the number “1”, the number “5” is placed between the numbers “1” and “2”, and the number “6” is placed above the number “2” and “3”. The number "7" is placed below the number "3". Similarly, in the third column, r8, 9 . If the IOJ number is between "4" and "5", "5" and "6", or "6", respectively
and "7". Similarly, in the fourth column, the numbers "11 to 14" correspond to the numbers "4 to 14" in the second column.
The numbers ``7'' are arranged in the same position as the numbers ``15-17'' in the fifth column, and the numbers ``8-10'' in the third column.
It is placed in the same position as the number. Similarly,
The numbers "18-21" are in the sixth column, the numbers "22-24" are in the seventh column, and the numbers "22-24" are in the eighth column.
The numbers 5 to 28 are also 29 to 28 in the ninth column.
The numbers ``31'' are placed on each.

Furthermore, in the embodiment shown in FIG. 4, the numbers [1°2.3,4J are arranged in the first column in the vertical direction, that is, the leftmost column, and in the second column in the vertical direction. , "5"
The number "6" is placed between the numbers "2" and "3", the number "7" is placed between the numbers "3" and " It is placed between the numbers 4. In the third column, the number "8" is placed directly to the right of the number "1", that is, above the number "5", and the number "9" is placed directly above the number "5".
” and “6”, the number “10” is placed between “6” and “7”, and the number “11” is placed directly to the right of “4”, that is, “7”.
” is placed below. Similarly, in the fourth column, the numbers "12 to 14" correspond to the numbers "5 to 7" in the second column.
are placed in the same position as the numbers in the fifth column.
The numbers "15-18" are placed in the same positions as the numbers "8-11" in the third column. Thereafter, in the same way, the numbers "19 to 21" in the sixth column, the numbers "22 to 25" in the seventh column, and the numbers "26 to 25" in the eighth column.
-28'' numbers are arranged.

In the ninth column, numbers "29 to 31" are arranged. At this time, the number "29" becomes "
Above ``26'', the number ``30'' is ``26'' and ``27''.
In addition, the number "31" is "27" and "28"
The number ``25'' is left blank.

As mentioned above, in the embodiments shown in FIGS. 3 and 4, 3
Since the 1 digits and the 4 digits are arranged differently from each other, the advantage of identifying the 7 groups of digits by color is even greater.

In the embodiments shown in Figures 3 and 4, rows of numbers such as "1-3" and "4-7" or rows of numbers such as "1-4" and "5-7" are arranged in the vertical direction. Alternatively, these numbers may be arranged horizontally. In that case, rows of identically colored numbers appear vertically.

In all of the above embodiments, the day of the week display column 28 for each year in the day of the week display section 14 displays several years together in one place below the calendar day display section 12. Alternatively, the day of the week display section 14 made up of a group of day of the week display columns 28 for several years may be arranged above, on the left side, or on the right side of the calendar day display section 12. Furthermore, such a group of day of the week display columns may be written on a relatively large sheet of paper at a location away from the calendar day display section.
