Description

[Detailed Description of the Invention] The present invention relates to an electronic timepiece structure having an analog display section and a digital display section.

In recent years, a watch that has integrated a luxurious analog watch and a highly functional digital watch into one watch, a combination in which a liquid crystal cell is placed in a window formed in a part of the dial of the analog display. Watches became popular.

However, although the combination watches currently on the market have the same level of functionality as digital watches, they are not as luxurious as analog watches.

The structure of a conventional combination watch will be explained below. FIG. 1 is a front view of a conventional combination watch, and FIG. 2 is a sectional view taken along line A-A in FIG.

1 is a combination watch, 2 is a case, 3 is a dial, 4a is an hour hand, 4b is a minute hand, and 4c is a second hand; dial 3, hour hand 4a, minute hand 4b, second hand 4c.
This constitutes the analog display section 4. Also, dial 3
A liquid crystal cell 5 is disposed in a window portion 3a formed by punching out a portion of the screen using a press, thereby forming a digital display portion 6.

In FIG. 2, 3 and 5 are the dial and liquid crystal cell shown in FIG. 1, 7 is a reflective plate, 8 is an IC, 9 is a circuit board, 10 is a conductive rubber, and 11 is a liquid crystal cell support frame. The IC 8 is mounted on a conductive pattern formed on the upper part of the circuit board 9. In addition, the liquid crystal cell 5 includes an upper polarizing plate 5a, an upper glass 5b, and a lower glass 5.
c, it has a laminated structure with a lower polarizing plate 5d.
A display pattern for driving the liquid crystal cell 5 is provided on the upper end surface 9a of the circuit board 9 on which the IC 8 is mounted. It is configured to establish electrical continuity with the display electrode. The liquid crystal cell support frame 11 fixes the circuit board 9, the conductive rubber 10, and the upper glass 5b so as to sandwich them from above and below. A liquid crystal cell spacer 12 that is slightly thicker than the IC 8 is provided between the conductive rubber 10 on the circuit board 9 and the IC 8 to prevent the IC 8 and the reflecting plate 7 from coming into contact with each other. The whole structure is
On the top of the circuit board 9 on which the IC 8 is mounted, a reflector 7, a liquid crystal cell 5, a cell support frame 11, and a dial 3 are placed.
It has a laminated structure. The liquid crystal cell support frame 11 needs to be hidden under the dial 3 in order not to damage its appearance, and the polarizing plate 5a is also hidden behind the dial 3.
In the conventional structure described above, the thickness of the dial 3 casts a shadow on the digital display section 6, and the user feels that the entire liquid crystal cell 5 sinks. In addition, there was a drawback that the dial 3 and the digital display section 6 lacked a sense of unity, detracting from the sense of luxury as a whole.

The purpose of the present invention is to eliminate the many drawbacks of conventional combination watches as described above, and to provide a combination watch that is as luxurious as an analog watch.

FIG. 3 is a sectional view of the main parts of the combination watch according to the present invention, showing the same cross section as FIG. It has the same structure as a conventional combination watch and is not shown in the drawings. In this embodiment, a bent portion 3b is formed downward around the window portion of the dial 3' by drawing, and this bent portion 3b is connected to the upper support end surface 11a of the cell support frame 11 and the upper deflection plate end surface 5e. The end surface of the bent portion 3b of the dial 3' is arranged in the same plane as the end surface 5e of the upper deflection plate.

According to the structure of this embodiment as described above, since there is no shadow cast on the digital display section due to the thickness of the dial plate, there is no sense of distance between the liquid crystal surface of the digital display section and the dial panel. This creates a sense of unity with the digital display, and also improves the sense of luxury by hiding the stamped-out traces of the window formed on a portion of the dial. In addition, since this invention can be made with a simple drawing process, there is no need to add complicated manufacturing processes, and it can be supplied at almost the same cost as conventional watches, which has a great effect on improving the product appeal of combination watches. be.
