Abstract

An information display device includes a dial plate having a display window; a rotatable date display plate provided under the dial plate and having dates to be selectively displayed through the window; an information display plate provided between the dial plate and the date display plate and including a display portion having an information item on a top surface thereof; an information display plate driver capable of moving the information display plate to any one of first and second positions. When the information display plate is in the first position, the display portion does not lie just under the window and a date in a position corresponding to the window is displayed through the window. When the information display plate is in the second position, the display portion is in a position corresponding to the window.

First claim

What is claimed is:

1. An information display device comprising:
a dial plate having a display window;
a rotatable date display plate provided under the dial plate, the date display plate having a plurality of dates to be selectively displayed through the display window;
an information display plate provided between the dial plate and the date display plate, the information display plate including an information display portion having a non-date information item on a top surface thereof, the non-date information item being different from the dates; and
an information display plate driver capable of moving the information display plate to any one of a predetermined first position and a second position, wherein, when the information display plate is in the first position, the information display portion does not lie just under the display window and a date of the dates in a position corresponding to the display window is displayed through the display window; and when the information display plate is in the second position, the information display portion is in a position corresponding to the display window.

2. The information display device according to claim 1 ,
wherein the information display plate is rotatable; and
wherein the date can be displayed through a predetermined part of the information display plate and through the display window.

3. The information display device according to claim 2 , further comprising an information display plate drive controller which controls the information display plate driver to operate according to information to be output,
wherein the date display plate rotates in conjunction with a rotation of the information display plate;
wherein the information display plate drive controller rotates the date display plate along with the information display plate to change the date to be displayed; and
wherein the information display plate drive controller rotates the information display plate while the date display plate is standing still to switch an information item to be displayed, so that one of the date and the non-date information item according to the information to be output is displayed through the display window.

4. The information display device according to claim 3 ,
wherein the date display plate rotates in conjunction with a predetermined part of the rotation of the information display plate; and
wherein the information display plate drive controller rotates solely the information display plate except for the predetermined part of the rotation of the information display plate to switch the information item to be displayed through the display window.

5. The information display device according to claim 1 , further comprising a wireless communication unit which performs wireless communications with an external device,
wherein the non-date information item corresponds to information received by the wireless communication unit from the external device.

6. The information display device according to claim 1 , further comprising:
an illuminator which illuminates the information display plate; and
an illumination controller which controls the illuminator to illuminate the information display plate while the information display portion is in a position corresponding to the display window.

7. An analog electronic timepiece comprising:
the information display device according to claim 1 ;
a time calculating unit which calculates a time; and
a plurality of rotatable hands provided on the dial plate, the hands pointing to the time calculated by the time calculating unit.
