Abstract
An analog electronic time piece includes a dial plate in which two openings are formed, two electric-optical display panels arranged below the openings, and a shutter plate rotatably arranged between the dial plate and the display panels. There two openings are closed by the shutter when it is rotated to a first position. One of the two openings is closed and the other is opened by the shutter when it is rotated to a second position. The above described one opening is opened and the other is closed by the shutter when it is rotated to a third position. The two openings are opened by the shutter when it is rotated to a fourth position.
Claims28
An analog electronic timepiece comprising:
- a dial plate in which at least two openings are formed;
- time-indicating hand means for pivotally moving hands on said dial plate to indicate the time;
- at least two electric-optical display means mounted below said dial plate to correspond to the openings;
- a single shutter plate rotatably mounted between said dial plate and said electric-optical display means;
- and
- shutter-plate movement control means for controlling said single shutter plate to move it to a desired position including first, second, and third positions in its rotational direction;
- wherein said single shutter plate is formed in such a shape that it opens all the openings of said dial plate when said shutter plate is located at its first position in its rotational direction, closes all the openings of said dial plate when said shutter plate is located at its second position in its rotational direction, and opens at least one of the openings and also closes at least one of the remaining ones of the openings when said shutter plate is located at its third position in its rotational direction.
