【Example】

 An embodiment of the present invention will be described with reference to the drawings. The base material 3, the date display panel 4 and the day of the week search panel 5, which are constituent materials of the present invention, are all made of a suitable material such as a synthetic resin material or a hard paper material. It is formed in a substantially circular shape using a plate material of a material. In this embodiment, since a locking portion 6 which can be locked to a key ring or the like is projected from an upper portion of the base 3, it is particularly suitable as a portable perpetual calendar.

As shown in FIG. 1, a base 3 formed in a slightly larger circular shape and a date display panel 4 formed in a smaller circular shape than the base 3 are provided on the front part of the perpetual calendar of the present invention. Thus, a calendar display unit 1 is provided. The base 3 is provided with a day display column 8 on its outer peripheral frame (outside the periphery of the date display panel 4). The day of the minute is shown. In other words, in this column, two days of the week are displayed such that the last day of the next week starts on Sunday and ends on Sunday.

A date display panel 4 is provided at the front of the base 3 so as to be rotatable around a pin 7 described later as a fulcrum. The date display panel 4 is provided with a rectangular frame line, and a date display box 9 in which six vertical lines and four horizontal lines are drawn. In the date display column 9, numbers 1 to 7 are displayed from the left in the uppermost row, and numbers 8 to 14 are displayed in the next row. Monthly dates are displayed sequentially. Further, outside the upper frame of the date display section 9, a connection line 12 for connecting the vertical line of the above-mentioned date display section 9 and the dividing line of the day display section 8 of the base 3 is written. The connection line 12 is provided for communicating and displaying the day of the week starting from the day of the first day of the month to be displayed on the calendar and the dates 1 to 7.

Next, the day of the week search unit 2 will be described with reference to FIG. The day-of-week search unit 2 includes a base 3 and a day-of-week search panel 5 formed in a circular shape smaller than the date display panel. The day of the week search board 5 is provided with a search day of the week display column 11 in which, like the day of the week display column 8 of the base 3, starting from Sunday, the last day of the next week is Sunday. I have. Since the pin 7 is inserted from outside the center of the day of the week search board 5, each component is rotatable around the pin as a fulcrum.

A year / month display section 10 is provided on the outer peripheral frame of the base 3, and the year / month display in the year / month display section 10 indicates a single number of each month in one section. Instead, one or more month numbers are displayed in one section. This shows the months starting from the same day of the week in one block, and the first day of the month follows the order of the day of the week, so that the first day of the month follows the day, month, fire, and so on. They are arranged in order. That is, as shown in FIG. 2, January 1 and October 1 correspond to the same day of the week, and May 1 corresponds to the day following January 1 and October 1. It is supposed to do it. The most important part of the present invention is that the search day display column 11 and the year / month display column 10 are configured to correspond to each other.

The perpetual calendar of the present invention configured as described above has a day of the week display field 8 provided on the base 3 of the calendar display unit 1 and a date of the date display field 9 provided on the date display panel 4. Is displayed so that the calendar of the specific month to be displayed on the calendar is displayed. The combination of the day of the week and the date is performed through the following procedure.

For example, assuming that today is October 20 but it is desired to know what day March 3 was this year, a procedure for displaying a March calendar on the calendar display unit 1 will be described. Will be described.

First, the day of the week of March 1 is searched by the day of the week search unit 2 on the back side of the calendar. In this case, it is confirmed that October 1 is Tuesday, and October is designated as a search reference month, and Tuesday is designated as a search reference day. Then, as shown in FIG. 2, when the numeral “10” displayed in the year / month display section 10 is matched with “Tue” in the search day display section 11, the 3 displayed in the year / month display section 10 is matched. It is determined that the first day of the month (the day of March 1) is “Fri”. Therefore, on the front side of the calendar, as shown in FIG. 1, "Fri" of the day of the week and "1" of the number representing March 1 of the date are communicated. The calendar for March of this year, in which the day of the week and the days 1 to 7 are respectively contacted, such as "day" is contacted with "3", is displayed. As a result, it turns out that March 3 was Sunday. The above is the method of searching for the day of the week and the method of displaying the calendar within the same year.However, the search reference month shown here is not necessarily limited to the month when it is used, and the search reference day is clearly identified. You can specify any month as the search reference month.

Next, a calendar display of a specific month in a future year or a past year will be described. In other words, to search for the day of the week in the next year, specify the search reference day of the week next to the search reference day of the current year, and in the case of last year, specify the day of the week before the search reference day of the year. I do. That is, if the current year is 1996, the search reference month is October, and the search reference day is Tuesday, in 1997, as shown in FIG. 4, the search reference month is October, and the search reference day is October. On Wednesday so that they match. Conversely, in 1995, the search reference month is designated as October, and the search reference day is designated as Monday. In addition, when displaying a calendar before or after several years, the search base day is moved up or down based on the search base month of this year according to the difference in years from the past or future. To Based on the day of the month that should be displayed as a result, the calendar is displayed in the manner described above.

Furthermore, leap years come once every four years. In the Christian era, the last digit comes in the order of 4, 8, 2, 6, 0, so it is necessary to consider this point. However, only in the cases of 2 and 6, when the last two digits are odd, the last two digits are odd, and for example, the last two digits are even, such as 1992, 1996, 2000, and 2004. It is important to keep in mind that 2,6 are not leap years.

Next, another embodiment of the present invention will be described with reference to FIG. In this embodiment, two bases are provided. A date display panel 4 similar to the above embodiment is mounted on the base 3 to form a calendar display section 1, and a day of the week search panel is provided on the rear surface of the base 3A. 5 to form the day of the week search section 2. Further, since the locking portion 6 is connected to the base 3A, the base 3A is rotated so as to match the date display section 9 of the calendar display section 1, so that the date displayed on the calendar is always in the front position. It can be provided. Therefore, the perpetual calendar of this embodiment is suitable for hanging on a wall or the like.

In FIG. 2 of the previous embodiment, an example is shown in which the partition between the year / month display column 10 and the search day display column 11 is made smaller and the margin is increased. The column 11 may be displayed over the entire circumference, and the section of the year / month display column 10 may be expanded accordingly.
