In the illustrated embodiment, the minute wheel 32, hour wheel 36, and
The inner diameters of the internal teeth of the map image body 40 and the day / night display body 42 are made smaller in order, and they are respectively placed on the stairs of the upper outer periphery of the pedestal 10 in order from the lower tier to hold them concentrically and to be rotatable. In the illustrated embodiment, each of them is placed on the stepped portion of the pedestal 10, but they may be arranged such that sheet members having a small friction coefficient are sandwiched between the inner teeth so as to be stacked.

By the way, in the illustrated embodiment described above, the internal teeth 40a, 42a, 42b are formed on the map image body 40 and the day / night display body 42, respectively, toward the center thereof. However, not limited to the internal teeth, teeth extending in the axial direction may be formed so as to mesh with the gears on the apparatus main body side.

The display device according to the present invention is constructed as described above. Then, the timing motor 14 is driven to rotate the motor gear 22, and the 50/60 Hz switching gear 23 and 50/60 Hz
The rotation thereof is transmitted to the first gear 27 through the engagement with the corresponding gear 24. Then, the rotation of the first gear 27 is transmitted to the second gear 29, and the rotation of the second gear 29 is transmitted to the minute wheel 32 via the idler 31. By this, minute wheel 3
Rotate 2 once per hour. On the other hand, the rotation of the second gear 29 is transmitted to the fourth gear via the third gear 33, and the rotation of the fourth gear is transmitted to the hour wheel 36 via the idler 35. Then, the hour wheel 36 rotates once a day. Thereby, by reading the numerical values of the hour wheel 36 and the minute wheel 32 at the position of the time display mark 11, it is possible to know the time in Japan, for example. As shown in FIG. 5, the Japanese time mark 11
Not only the time display with country name and city name 44.4
If 5 is displayed on the outer circumference of the pedestal 10, the times of those countries or cities can also be known.

When performing time adjustment, the display device is lifted, the time adjustment knob 30 is pinched, and the time adjustment shaft 28 is rotated. Then, the second gear 29 rotates and similarly the minute wheel 3
2 and hour wheel 36 is rotated. At this time, the second gear 29
The first gear 27 meshing with the first gear 27 also rotates, but the first gear 2
7 slips between itself and the main shaft 25 to rotate its rotation.
5 is not transmitted.

By the way, when the 50/60 Hz compatible gear 24 rotates and the main shaft 25 rotates, the fifth gear 37 rotates and transmits the rotation to the map image body 40 via the idler 39. Then, the map image body 40 is rotated, for example, 800 times a day. Also,
When the main shaft 25 rotates, the sixth gear 38 rotates and transmits the rotation to the day / night display 42 via the idler 41.
Then, the day / night display body 42 is rotated one rotation less per day than the rotation of the map image body 40, for example, 799 rotations per day.

Then, the operating portion 19a of the blinking switch 19 for day and night display
By pressing, the light source 20 is turned on, and the light from the light source 20 is applied to the map image body 40 through the day / night display body 42, and the map image on the map image body 40 is displayed to indicate whether it is day or night. For example, as shown in FIG. 6, the day / night display body 42 is provided with a transparent portion a and a semi-transparent portion b, and the light transmitted through the transparent portion a illuminates the map image body 40 to make the map image of that portion appear bright. In this way, the light transmitted through the semitransparent portion b illuminates the map image body 40 so that the map image of that portion appears dark.

Now, the sunshine hours for one year change depending on the four seasons. Therefore, in the illustrated embodiment, internal teeth 42a and 42b are provided at the upper and lower ends, and the day / night indicator 42 is used as shown in FIG. 7 (A) when the northern hemisphere is summer, and the cap 13 is removed when winter. The day / night display 42 in the center is turned over as shown in FIG. 7 (B) and used. By doing so, it is possible to perform day and night display that matches reality with a simple configuration. Further, the cap 13 is removed, and the day / night display 42
Can be exchanged for another.

It should be noted that the map image body 40 and the day / night display body 42 are provided with marks so that they can be aligned with each other.

Therefore, according to this invention, since the map display body is rotated several times a day, it is possible to increase the fun of the display device. At the same time, the daytime display is rotated by one rotation less than the rotation of the map image body per day, so that the daytime display can be realized.
