As a result, an output is generated from the terminal 22C of the decoder 22, and the electrode 12C in FIG. 4 is selected.

Therefore, Tuesday of the first week, ie, the third day, is selected.

In this way, the items are sequentially selected up to the 7th. and midnight on the 8th
When the time comes, the counted contents of the counter 20 go through one cycle, an output is generated from the terminal 22a of the decoder 22, and the electrode 12a corresponding to Sunday in FIG. 4 is selected.

On the other hand, a pulse is generated from the terminal 20a of the counter 20, and the contents of the counter 21 are incremented by one.

Therefore, the electrode 13b corresponding to the second week in FIG. 4 is selected, and the Sunday of the second week, ie, the 8th, is selected.

The current date is selected sequentially.

Then, when the month changes, turn the rotary knob 4a shown in FIG. 1 to wind up the sheet 1 so that the month of March falls within the window 7.

On the other hand, the switch 16 in FIG. 5 is closed to reset the counter 21 and select the electrode 13a corresponding to the first week.

As a result, March 1st is selected, and the dates of that day are subsequently selected in the same manner as above.

In this manner, the manual operation involves winding up the calendar and closing the switch 16 when the month changes.

In this example, the current date is selected for several years during the months and years printed on the sheet.

By the way, in the above example, the current month and the months before and after it are also displayed, and the current day can be selected from among them, but if it is not necessary to display the months before and after, the window can be set to only one and only the current month can be selected. may be displayed.

Further, in the above embodiment, a sheet with a calendar for many months printed on it and rolled up was used as a display means, but the date of each month is printed on a separate sheet of paper,
You can also insert the current month's calendar into the window.

Next, an example in which a perpetual calendar is used as the calendar will be explained.

In FIG. 6, 25 is a frame provided with windows 25 a t 25 b, and 26 is a calendar disposed within the window 25 b.

The calendar 26 is a piece of cloth or the like on which a date is written as shown in FIG. 7, and both ends of the calendar are folded, and the calendar is fed by rollers 27 and 28 as shown in FIG.

The roller 27 is fixed to a shaft 29, the upper end of the shaft 29 is rotatably fixed to the frame 25 in FIG. 6, and the lower end is fixed to the frame 25.
It penetrates to the outside and fixes the knob 30.

The rollers 28, 31 are each fixed at both ends to shafts 32, 33 which are rotatably fixed to the frame 25.

The rollers 31 sandwich the calendar 26 and are in close contact with the rollers 27.

A clock device 34 is disposed in the window 25a in FIG. 6, and a liquid crystal panel 35 is disposed in front of the calendar 26 in the window 25b as shown in FIG.

Electrodes are formed on the opposing glass substrates of the liquid crystal panel 35, respectively, as shown in FIGS. 10 and 11.

In FIG. 10, one glass substrate 36 has electrodes 3 similar to those in FIG. 4 corresponding to the first to fourth weeks of the calendar 26.
6a...36d are formed, and electrodes 36et36f and electrodes 36g correspond to the fifth and sixth weeks.
36h is formed.

Reference numerals 37 and 38 indicate switches, which are switched between open and closed states each time the operation buttons 39 and 40 in FIG. 6 are pressed.

Electrodes 36a...36e and 36g are connected to terminals 24a...24f of the circuit of FIG. 5, respectively.

In FIG. 11, the glass substrate 41 has the electrode 12 shown in FIG.
a...Similar to 12g, the electrodes 41a and 41a correspond to each Yota.
... 41g are formed, and the electrodes 36f and 3 in Fig. 10 are formed.
Electrodes 41h...41n are also formed opposite to 6h.

42...48 are switches connected to the electrodes 41h...41n, respectively, and the switches 3γ and 38 in FIG.
6, and 49...55 in FIG. 6 are operation buttons for the switches 42...48, respectively.

The electrodes 41a...41g are respectively the terminals 22a in FIG.
...Connected to 22g.

Next, the operation will be explained.

First, date adjustment of the calendar 26 will be explained.

For example, if the first day of the current month is a Sunday, rotate the knob 30 in FIG. 6 to rotate the roller 27 in FIG. 8, turn the calendar 26 to the position shown in FIG. Make the 1st correspond to Sunday.

In this way, the date is made to correspond to the day of the week, and a voltage is applied to the electrodes 36a...36g and the electrodes 41a...41g of the liquid crystal panel 35 in exactly the same manner as in the above embodiment to select the date.

Now, the moon has a dog moon and a small moon, and February has two
There are up to the 8th or 29th, and dates after the 29th must be displayed selectively depending on the month.

Therefore, this selection operation will be explained. For example, assume that the correspondence between dates and days of the week is as shown in FIG. 6, and that this month is a small month.

In this case, the electrode 36f does not correspond to the fifth week in FIG.
The switch 37 connected to the electrode 41J corresponding to Tuesday in FIG. 11 is closed by operating the button 39 in FIG. 6, and the switch 44 connected to the electrode 41J corresponding to Tuesday in FIG. 11 is closed by operating the button 51 in FIG.

As a result, a voltage is applied only between the electrodes 36fj and 41J, the liquid crystal between them responds, and the 31st day in FIG. 5 becomes invisible.

By operating the switch button corresponding to the week and day of the week of the date to be erased in this way, the liquid crystal corresponding to that date is made to respond and becomes invisible.

Further, in the above embodiment, the date is automatically selected by counting the midnight signal from the clock device, but the invention is not limited to this, and a manual switch for selecting each day of the week and a manual switch for selecting each week can be provided. The selection may be made according to the following.

As detailed above, according to the present invention, the date on the display means is selected by driving the liquid crystal means provided opposite to the monthly calendar recorded on the sheet, so that simple operations can be performed every month. You can display dates over many years and months with just one.
