Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pointer type electronic timepiece having a display panel such as a combination watch.

[0002]

2. Description of the Related Art As a pointer type electronic timepiece, there is a combination watch having both a digital function and an analog function. In this type of pointer type electronic timepiece, in order to enlarge the digital display surface, a display panel having almost the same size as the display surface is used, a through hole is formed at the center of this display panel, and the display panel is formed in this through hole. The pointer shaft of the analog movement provided on the lower side is inserted, and the pointer is attached to the pointer shaft protruding to the upper surface side of the display panel. However, in such a pointer type electronic timepiece, since it is necessary to form a through hole through which the pointer shaft is inserted in the display panel, there is a problem that the manufacturing of the display panel is difficult and the cost is high. Therefore, in order to solve such a problem, conventionally, it has been considered to combine a plurality of display panels. In this pointer type electronic timepiece, a pointer shaft through hole is provided in the center of a housing made of synthetic resin, and two panel storage holes are provided so as to sandwich the pointer shaft through hole, and each side wall of the two panel storage holes is provided. It is necessary to provide elastic pressing pieces that press the display panels against the opposite side walls, and fix the two display panels in the panel housing holes by these elastic pressing pieces.

[0003]

However, in such a pointer type electronic timepiece, if the elastic pressing piece for fixing the display panel is simply provided on the side wall of the panel housing hole, the entire elastic pressing piece becomes the panel housing hole. It protrudes from the side wall,
There is a problem in that the size of the display panel is restricted by the elastic pressing piece, and the display surfaces of the two display panels become considerably smaller than the surface of the entire housing. The present invention has been made in view of the above circumstances, and an object thereof is that even if a plurality of display panels are combined, the display surface of the entire display panel is not so small with respect to the surface of the entire housing. It is an object of the present invention to provide a pointer type electronic timepiece equipped with a display panel capable of sufficiently securing the size of the display surface.

[0004]

In order to achieve the above-mentioned object, the present invention has a pointer shaft through hole formed at the center and two panel housing holes sandwiching the pointer shaft through hole. A housing made of synthetic resin, two display panels housed in the panel housing holes of the housing, and a display shaft provided below the two display panels, and a pointer shaft is inserted through the pointer shaft through hole. Each display panel has an analog movement protruding toward the front surface side, and each of the two display panels is located in a portion located between the pointer shaft through hole between the two panel storage holes and the outer peripheral portion of the housing. An elastic pressing piece that presses the opposing side walls of the storage hole is integrally formed.

[0005]

According to the present invention, the 2 provided on the housing
Since an elastic pressing piece that presses the two display panels against the opposite side walls of each panel housing hole is integrally formed in a portion located between the pointer shaft through hole and the outer peripheral portion of the housing between the two panel housing holes. , The entire elastic pressing piece does not project from the side wall of the panel housing hole, and only the abutting portion of the elastic pressing piece that abuts the display panel can project into the panel housing hole. The size of the panel is hardly restricted, and the size of the display surface of the two display panels can be sufficiently secured. In this case, as described in claim 2, a collar portion for locking the upper surface of each display panel is formed on each side wall of each panel housing hole facing the elastic pressing piece, and each elastic pressing piece is provided. Except for the part, if a flange that locks the upper surface of each display panel is formed on the side wall of each panel storage hole on the side of the pointer shaft through hole, each display panel arranged in each panel storage hole is elastically pressed. When pressing with one piece, even if each elastic pressing piece presses a position deviated from the center of each display panel, each collar can lock the upper surface of each display panel so that each display panel does not float up. .
