Includes seven types or 14 days of week series in which different days of the week are displayed depending on the days of the week (for example, one day) of each month for at least 11 months. The types are arranged along the moving direction. The date table 21 includes seven types of calendar areas configured from at least one month's worth of calendar dates, and these seven types of calendar areas are used for predetermined days (for example, 1
The date is classified according to the day of the week, and is formed by shifting the position along the moving direction. The chronological table shows a plurality of years, and a predetermined day of a predetermined month (for example, January 1st) in the represented year is classified into 7 types depending on the day of the week, and the movement is performed for each type. The display of each year is arranged at different positions along the direction. The day-of-the-week display window 12 is formed so that one or two columns of the above-mentioned day-of-the-week table 22 on the back plate 2 can be seen as partitioned. The date display window 13 is formed so that one type of calendar area of the date table 21 on the substrate can be divided and viewed. Then, the distance between the date display window 13 and the year displayed in the chronological table 11 becomes a calendar of a predetermined month (for example, January) of the year, and one kind of calendar area of the date table 21 and the reference point 23. Is set equal to the distance between. Also, the day display window 1
The distance between 2 and the year displayed in the chronological table 11 is set to be equal to the distance between the day of the week row and the reference point 23 of the day of the week table 22 corresponding to the year.

The perpetual calendar according to the third invention of the present application is based on the date of the date table 21 displayed on the back plate 2 seen from the date display window 13 in the perpetual calendar according to the first or second invention of the present application. It has an auxiliary plate 3 capable of concealing a part.

[0010]

In the fountain calendar according to the first invention of the present application, by setting the reference point 23 at a position corresponding to one year in the chronological table 11, the date table 2 seen from the date display window 13 is displayed.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view of a front plate 1 of a fountain calendar of one embodiment, FIG. 2 is a schematic view of a back plate 2 of the fountain calendar, and FIG. 3 is a schematic of an auxiliary plate 3 of the fountain calendar. FIG. 4 to FIG. 6 are schematic diagrams of the usage state of the calendar for the same year.

First, this perpetual calendar has a front plate 1 and
The front plate 1 includes a back plate 2 arranged on the back surface and an auxiliary plate 3 inserted between the plates 1 and 2.

The front plate 1 is provided with a column in which a plurality of years are arranged vertically.
Timeline 11 with seven columns side by side and day of the week display window 12
And a date display window 13, a month display means 14 from January to December is formed along the day of the week display window 12, and one week from Sunday to Saturday is formed along the date display window 13. A day of the week display means 15 is formed.

In the chronological table 11, the position where each year is described is determined depending on the day of the week based on a specific day of a specific month (for example, January 1 in this embodiment).
Since there are 7 days in a week, there are 7 positions. That is, the year shown in the chronological table 11 is classified into seven types according to the day of the week on which a given day (eg, January 1st) of a given month in the year is, and each type has a horizontal direction. The display of each year is arranged in different positions along the line.

In this embodiment, the date before February is used as a reference, but after March when a change occurs in the leap year, the table becomes different from that in this embodiment. In addition, it is desirable to change the color of the description of the normal year and the leap year so that the normal year and the leap year can be easily distinguished. In the drawings, leap years are underlined. Further, in this embodiment, the display from 1995 to 2100 is directly written on the front plate 1, but which year is displayed may be changed appropriately. Further, the card may be replaced by a replaceable card instead of being written directly. Alternatively, the chronological table may be described on a belt or roller that can be sequentially fed, and the chronological table on the belt or roller may be viewed from a window opened in the front plate 1. In this case, it is not necessary to vertically arrange a plurality of years, and only one example may be used, or one year may be written on a belt or a roller at a predetermined position so that the years can be seen in sequence.

The day display window 12 and the date display window 13 are formed by cutting out the front panel 1, but the front panel 1 is formed of a transparent synthetic resin plate, and the day display window 12 and the date display window are formed. 1
It may be used as a window by coloring parts other than 3.
The entire front plate 1 may be left transparent, and only the outer peripheral lines showing the day of the week display window 12 and the date display window 13 may be described as a window. In short, the day of the week display window 12 and the date display window 13
Is sufficient if it can be seen from the other side of the front plate 1 and its back side can be seen.

The month display means 14 and the day of the week display means 15 are
Although the month and the day of the week are shown on the front plate, the month and the day of the week can be shown without the description by simply adding a scale or by the shapes of the day of the week display window 12 and the date display window 13 themselves. You may make it recognize. For example, the date display window 13 is formed with a division line 15a for Sunday display that divides only the Sunday portion, but even with only this, the day of the week can be recognized. The partition line 15a may be provided on Saturday, or the partition line may be slidable so that it can be changed according to the convenience of the user. Further, instead of the dividing line, only the Sunday portion of the date display window 13 may be covered with a red colored transparent plate. Further, in this embodiment, "normal year" is displayed on the left side of the upper part of the day display window 12.
Display 12a is displayed, and "Leap year" display 12b is displayed on the right side.
Is described.

In addition to the above construction, the front plate 1 is provided with a back plate slit 16 and an auxiliary plate slit 17. In this embodiment, since the back plate 2 and the auxiliary plate 3 are set to slide in the left-right direction, the back plate slit 16 and the auxiliary plate slit 17 are also extended in the left-right direction.

Next, the back plate 2 will be described.
Includes a date table 21 showing dates for one month or more, and a day table 22 showing a plurality of days of the week (day of the week or seven kinds of displays corresponding to the days of the week) horizontally and a plurality of columns vertically. , Reference point 23
Are formed.

In this embodiment, the date table 21 adopts a description system in which dates for one week are arranged in horizontal rows, and a basic array portion 21a in which 1st to 31st days are arranged according to a normal calendar. And an additional array portion 21b additionally described. Explaining the additional array portion 21b, first, in the calendar, when a specific day of the month (for example, one day) is a day of the week from Sunday to Saturday is different depending on the month. 7 types
It is a kind. Therefore, it suffices if the date table 21 can display 7 ways, and since one kind of arrangement is made in the basic arrangement part 21a, the additional arrangement part 21b is provided so that the remaining 6 ways can be displayed. Form. In the case of this embodiment, since the description method in which the dates for one week are arranged in the horizontal columns is adopted, the arrays (2 to 7, 9 to 14, 16) corresponding to the dates for 6 days of 2 to 7 are adopted. ~ 21,23 ~ 28,30 ~
31) may be formed. In this embodiment, the additional array portion 21b is provided on the left side of the basic array portion 21a, but it may be on the right side or may be divided into left and right sides.

From another point of view regarding the date table 21, the date table 21 includes seven types of calendar areas composed of calendar dates for at least one month, and these seven types of calendar areas are also included. The calendar area is classified according to the day of the week on which a predetermined day (for example, one day) corresponds, and is formed by shifting the position along the left-right direction. The areas divided by the two-dot chain line in FIG. 2 indicate the calendar areas 211 and 217. In the figure, two calendar areas (a calendar area 211 in which one day is Sunday and a Saturday in one day) are included in order to prevent complexity. Although only the calendar area 217) is shown,
The calendar areas 211 and 217 are deviated by one day, so that one day is Monday, one day is Tuesday, and one is Tuesday.
There are 5 types of day, Wednesday is 1st, Thursday is 1st, and Friday is 7th in total.
It includes the types of calendar areas.

Further, in this embodiment, the description method in which the dates for one week are arranged in the horizontal row is adopted, but the description method in which the dates for 1 to 31 days are arranged in one horizontal row may be changed. In the case of arranging in one horizontal row, it suffices to form an additional array part for only 1 to 6 days after the basic array part for 1 to 31 days.

In the present embodiment, the date display window 13 employs a description system in which dates for one week are arranged in horizontal rows, so that seven days in the horizontal direction and six days in the vertical direction are used. It is formed in such a size that the date table 21 appears. In addition, from 1 to 31 days,
In the case of adopting the description system arranged in one horizontal row, the date display window 13 is formed in a size in which the date table 21 for 31 days appears laterally.

According to the day of the week table 22, a predetermined day (for example, one day) of at least 11 months (12 months in this embodiment) of one year corresponds to a day of the week. 7 or 14 kinds (14 kinds in this embodiment) of day groups 22a and 22b in which different days are displayed are arranged along the moving direction. In other words, the day of the week table 22 is based on a specific day of one month (for example, one day in this embodiment), and a specific day of each month (for example, this implementation) from January to December. It is a table in which what day of the week (in the example, 1 day) is described. That is, for example, the day of the week table 2
If January 1st of a year is Saturday, then February 1st is Tuesday, March 1st is Tuesday, and December 1st is Thursday, as shown in the leftmost vertical column of 2. The days of the year are constant, except for leap years, no matter what the year. The leap year is 2 if January 1st of a year is Saturday, as shown in the second column from the left in the day-of-week table 22.
Tuesday is the 1st of the month, Wednesday is the 1st of March, and Friday is the 1st of December, so a day of the year is constant no matter what the year. Since there are 7 days in a week, there are 7 combinations for specific days in each month, 7 combinations for normal years and 7 combinations for leap years, for a total of 14 combinations.

Therefore, on a specific day (eg, 1
7 types of weekday categories 22a displaying the days of the week, 7 types of leap year categories 22b displaying the days of a specific day (for example, 1 day) of each month of the leap year, and 22 categories To display. In this embodiment, January and February are the same for both the normal year and the leap year, and therefore the weekday group 22a and the leap year group 22b in which January and February are the same are arranged side by side. . In addition, it is desirable to change the color of the description between the normal year and the leap year so that the normal year and the leap year can be easily distinguished. In the drawings, leap years are underlined. Since the leap year is only one day off from the normal year after March (for example, if March 1st is a Tuesday, March 1st is a Wednesday), only the weekday group 22a May be displayed, and the leap year / day category row 22b may not be displayed, and the leap year / day category row 22b may be adjusted by the user. Further, in the embodiment, each type of day-of-the-week column is arranged vertically in one column.
It may be arranged in two columns from December to December.

The seven rows of the weekday category row 22a and the seven columns of the leap year category row 22b respectively correspond to the seven positions of the years listed in the chronological table 11. Specifically, it corresponds to seven types of positions determined by the day of the week on the basis of a specific day of a specific month (for example, January 1 in this embodiment). More specifically, "1995", which is the farthest left of the chronological table 11, is the day of the week table 2
The weekday group 22a (1) listed on the rightmost side of 2
It corresponds to the column indicating that the 1st day of the month is the “Sunday” day), and the “20
The "00" year corresponds to the weekday category column 22a (column indicating that January 1st is "Saturday") that is listed on the leftmost side of the weekday table 22.

In the present embodiment, the above-mentioned day of the week display window 14 includes both the weekday category row 22a and the leap year category row 22b in the day category table 22. The vertical size is such that the days of the week for December appear.
If you do not enter the leap year / day category column 22b, enter 1 beside it.
The size may be set such that the day of the week for December appears vertically in rows. At this time, it is desirable to describe in the vicinity of the day-of-the-week display window 14 that "the leap year deviates from the normal year by one day after March".

The reference point 23 indicates a reference for operating the calendar table in accordance with the chronology 11 on the front plate 1, and can be confirmed from the front plate 1. In this embodiment, the reference point 23 is the back plate slit 1
It is a knob-like projection that fits in 6 and can be slid. Then, the reference point 23 (that is, a knob-shaped protrusion)
The back plate 2 is slid while holding, and the reference point 23 is aligned with the position corresponding to the desired year in the chronological table. As described above, in this embodiment, the reference point 23 serves both as a reference to correspond to the chronological table 11 and as a knob as the operation means of the back plate, and the back plate slit 16 is provided. Is provided below (or above) the chronological table 11, but both functions may be realized separately. For example, the arrow-shaped reference point 23a is projected from the upper end of the back plate 2 to make the timetable 11 of the front plate 1
Be able to point to the chronological table 11 from above the outside of the
The knobs for sliding the back plate 2 may be provided at completely different positions. Also, for sliding the back plate 2,
The back plate 2 may be slid in a dial type using a rack and a pinion. The front plate 1 and the back plate 2 need only be relatively movable, and the front plate may be moved. Further, the front plate 1 and the back plate 2 may be separated so that when used by a person, the two may be manually overlapped and used.

Next, the auxiliary plate 3 is a part of the date of the date table 21 displayed on the back plate 2 which can be seen from the date display window 13 in the calendar (specifically, 28 corresponding to a small month).
It is a plate-shaped object that can conceal (from day to 31st)) and is provided with a sliding knob 31. The knob 31 projects from the auxiliary plate slit 17 of the front plate, and the user can move the knob 31 to hide a part of the date table 21. Although the auxiliary plate 3 is arranged between the front plate 1 and the back plate 2, it may be arranged on the front plate 1 to hide a part of the date display window 13. Further, in this embodiment,
The auxiliary plate 3 is provided with an auxiliary date display 32 from the 1st to the 14th so that a part of the date table 21 can be hidden and a part of the date of the next month can be displayed.

Here, a specific method of using this perpetual calendar will be described by taking January 1995 and February 1995 as an example. First, FIG. 4 is an example showing a calendar for January 1995, and the operation is as follows.
The back plate 2 is simply slid so that the reference point 23 comes under the display of "5".

Next, FIG. 5 is an example showing a calendar for February 1995, and the operation is as shown in FIG.
The day of the week in the position of February on the day of week display window 12 is confirmed. In this case, since there is no underline in 1995 of the chronological table 11 and it is a normal year, the day of the week (left side) of the normal year, that is, “Wednesday” is confirmed. This "Wednesday" indicates that February 1st is Wednesday, so slide the back plate 2
The "1" of the date display 21 is brought to the "water" position of the date display window 13. With this, 199 in the state where up to 31 days are displayed, which is similar to the calendar shown in the above-mentioned conventional example.
The February 5 calendar is shown. In the case of a leap year, check the days of the week (right side) and move the back plate based on the result.

In order to bring the "1" of the date display 21 to the "water" position of the date display window 13, while directly looking at the "1" of the date display 21 appearing in the date display window 13, You can go, but you can use other methods. For example, at the same positions as the seven positions of the year described in the chronological table 11, seven types of day-of-the-week display 7 for positioning from Sunday to Sat.
(See FIG. 6). Then, by moving the reference point 23 to the position of "water", the same calendar as that described above starting on Wednesday can be displayed. By thus providing the day of the week display 7 for positioning, it is possible to display the calendar for each month of each year only by operating the reference point 23. Moreover, in this case, the day of the week table 2
The day of the week 2 and the day of the week display 7 for positioning may be set to other seven types of display (for example, alphabets A to G) instead of displaying the day of the week.

In the claims, "The day-of-week table 22 shows different days depending on how many days of the year (for example, one day) a predetermined day of at least 11 months of the year corresponds to. There are seven types of day-of-the-week series, which are displayed along with the type, and are arranged along the movement direction. ”For the following reason. That is, for one month in December of the year, as described above, the reference point 23 should be under the display of "1995" of the chronological table 1 without looking at the day of the week table.
It can be displayed only by sliding the back plate 2, and it is only for 11 months that the day of the week table needs to be viewed. Therefore, the description can be omitted by omitting the description of one month that can be determined without looking at the day of the week table.

Finally, in order to more accurately show the February 1995 calendar, the auxiliary plate 3 is slid as shown in FIG. That is, since February 1995 is until 28th, the date after 29th is hidden by the auxiliary plate 3. In this embodiment, the auxiliary date display 32 displays the first half of the next month (March). In addition, the above 1
Also in the case of January 995, the auxiliary plate 3 may be slid to display the date of the first half of February.

The above operation is realized from the following first and second positional relationships. First of all, the first positional relationship is chronological table 1
When the reference point 23 is aligned with the position corresponding to one year of 1, the date of the date table 21 visible from the date display window 13 and the day of the weekday display means of the date display window 13 are set to a predetermined value of the year. The chronological table 11, the date display window 13, and the reference point 23 are arranged in the positional relationship that matches the date of the month (for example, January) and the day of the week.
And the date table 21 are arranged. More specifically, the distance between the date display window 13 and the year displayed in the chronological table 11 (for example, a1 in 1995, a2 in 2000) is determined by a predetermined month (for example, a1). The distance between one type of calendar area of the date table 21 that serves as a calendar for January and the reference point 23 (for example, a1 ′ in the case of 1995,
In the case of 2000, it is set equal to a2 ').

The second positional relationship is that when the reference point 23 is aligned with the position corresponding to one year in the chronological table 11, the days of the week displayed on the day of the week display window 12 and the day of the week display window 12 are displayed. The chronological table 11 and the day-of-the-week display window are arranged in such a positional relationship that the month of the month display means coincides with the predetermined date (for example, the first day) of each month from January to December of the year and the day of the week. 12, the reference point 23, and the day of the week table 22 are arranged.
