 Technical field

 [0001] The present invention relates to a perpetual calendar. Specifically, it relates to a perpetual calendar that displays days and holidays.

 Background art

 [0002] The calendar is indispensable for daily life, and various items are provided every year to be replaced with new ones every year. The calendar is mainly used every year, but there is a so-called perennial calendar that can use one calendar every year. This perennial calendar is designed to accommodate any calendar by shifting the day of the week or changing the combination of day and day.

 [0003] Conventionally, various perennial calendars have been proposed. For example, FIG. 8 is a schematic diagram for explaining a conventional perpetual calendar, but Patent Document 1 discloses a base as shown in FIG. 101 and recesses S1-S6, recesses M1-M6, recesses T1-T6, recesses W1-W6, recesses TH1-TH6, recesses F1-F6, recesses SA1-SA6 Describes 31 daily pieces K1 to K31 that are detachably attached to the 12-month piece G1 to G12 and a fountain force render A that is composed of power.

 Further, Patent Document 1 is provided with a locking portion 110 that suspends the perpetual calendar A on the base 101, and the surface of the base 101 has seven days of the week (SUN, MON, TUE, WED, T (HU, FRI, SAT) is displayed, and seven display units 111 are provided. The upper left of the display unit 111 is provided with a month display unit 112 that displays the month. Or the two sides of the cube indicate that the numbers are the same, but the circumference of the numbers is different, so that days off and days off are not identified.

Furthermore, in Patent Document 1, 31 daily pieces K1 to K31 are inserted into each recess by identifying the days of holidays and the days when there are no holidays, and among 12 pieces of monthly pieces G1 to G12. One month piece corresponding to the month is inserted into the first recess M, and the remaining 11 month pieces represent the moon in the recesses where 31 daily pieces K1 to K31 are not inserted. Make sure that the side without numbers is on the front It is stated that it should be fitted in.

 And by changing the surface of the daily piece in this way, the days of rest and the days of no rest are displayed in different colors, so that it is easy to view and user-friendliness is improved.

And an extruding member 8.

 [0020] The first date display member, the second date display member, and the third date display member are the "29" date display block body 5A, "30" date display block bodies 5A and "31", respectively. The power of the day display block body 5A is included. These day display block bodies are not fixed to the adjacent day display block body 5A or the plain block body 5B, but only the 28th month, only the 29th day. Depending on the month and the month until 30th, depending on the month and the month until 31st, the surface on which the day is displayed cannot be seen so that it is placed upside down and has the same appearance as the plain block body 5B. Become. Fig. 1 shows an example of the calendar for June, so the date display block 5A of "31" cannot see the surface on which the day is displayed! /, So it is placed inside out! RU

 Also, the plain blocks 5B are arranged together with the day display members without being fixed, and the lengths of the respective rows are made equal to facilitate sliding in the left-right direction.

 Next, an example of using a perpetual calendar to which the present invention is applied will be described.

 When the month changes and the calendar is changed to a new month, the month display member 3 fitted in the bottom plate groove 2E is taken out, and the month display member 3 displaying the current month is turned over and is fitted into the bottom plate groove 2E again.

 Next, release the stopper 7 and the stopper receiving portion 5C, and slide the date display member 5 and the plain block body 5B to the left or right to align the first to seventh date display members 5 and the day of week column. To do.

 In addition, there are seven day-of-week display members 4 for each day of the week, and they are detachably attached to the main body 2. Therefore, only the type in which a week starts from Sunday, that is, the day-of-week display member is arranged at the leftmost position. It can also be in the form of a week starting on Monday.

In addition, for example, the date display block body 5A of “4” of the fourth date display member is connected to the first date display section. When placing in the same row as the “1” day display block body 5A, move the plain block body 5B adjacent to the “4” day display block body 5A and move the “25” day display block body. Solid block adjacent to 5A Place at the bottom to be adjacent to 5B. On the other hand, for example, when the “3” date display block 5A of the third date display member is arranged in the same row as the “8” date display block 5A of the first date display member, the Move the plain block 5B placed at the bottom and place it on top so that it is adjacent to the “3” date display block 5A.

 In addition, in order to display the day display member 5 arranged in the row of the day of the week display member 4 on Sunday as Sunday, or to display the day display block body 5A corresponding to a holiday as a holiday, use the extruded member 8 to display the date. When the holiday display member 6 is pushed out, the day / holiday display member 6 in a hidden state is seen from the surface of the day display member 5 on which the day is displayed, and a part of the day / holiday display member in red is displayed. Acclimate.
