Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic digital display timepiece using an electro-optical display as a display means.

Traditionally, electronic digital display watches have been
Using a crystal oscillator as a reference signal source, LCD, LED, EC
(Electrochromic) etc. are used as a display means.The present invention relates to the improvement of such digital display watches. This is an attempt to accommodate variety.

Being able to create many different watch designs with one type of movement is ideal in all respects, not only for digital display watches but for all watches, especially for women's watches or dress watches. However, in reality, there is a limit to the variety of designs that can be achieved with a single type of movement, and this type of watch on the market currently has a small movement, such as a women's watch, instead of a large one. They can be found in men's dress watches with various designs, but until now, watches of the same size but with completely different design systems have not appeared.

Against this background, the present invention aims to make it possible to obtain watches of various designs of the same watch size using a type of movement in an electronic digital watch that uses an electro-optical display as a display means. This will be explained below using examples.

Figures 1 and 2 and Figures 3 and 4 are plan views of watches showing one embodiment of the present invention, and all are various watches designed with the same movement.
As shown, the watch has a completely different appearance.
As is clear from Fig. 1 (Fig. 3) and Fig. 2 (Fig. 4), the gist of this invention is to use the same movement with the watch band 1 (the watches shown have a watch band and a watch case). ), by arranging them both vertically and horizontally, the aim is to obtain a variety of designs with almost the same size, and the aspect ratio of the movement's external dimensions becomes clear. The more different you are, the more you can get watches with different design families.

Hereinafter, embodiments of the present invention will be described in detail.

Figures 5 and 6 are similar to Figure 1 (Figure 2, Figure 3,
The structure shown in FIG. 4 is similar. ) is an assembled sectional view and an assembled plan view of a so-called liquid crystal display watch that uses a well-known liquid crystal panel as a display body. In the liquid crystal panel 2, liquid crystal is sealed between an upper panel glass 3 and a lower panel glass 4, and an upper polarizing plate 5 and a lower polarizing plate 6 with a reflective surface are integrally constructed as shown in the figure. It is connected to the circuit block by connectors 8 and 9 made of well-known zebra-type conductive rubber.
The connectors 8 and 9 are arranged on the shorter side of the liquid crystal panel in order to make the watch smarter. This is because the thickness of the watch case needs to be increased by the connector space in the area where the connector is placed, and the aim is to reduce the thickness when the movement is placed vertically or horizontally relative to the watch band. In the case of the example, the connectors were placed on two sides of the movement, but if the number of display segment terminals on the liquid crystal panel is small, such problems can be further improved by placing the connectors on only one side. . The circuit block has a MOSIC chip 11 bonded onto a double-sided copper-clad circuit board 10 made of epoxy resin or the like, and a mold frame 13 which is also a frame for molding the MOSIC chip part and a guide member for a button-shaped small battery 12 for power supply. Further, a crystal oscillator 14, a trimmer capacitor 15, a cathode terminal plate 16 and an anode terminal plate 17 of the battery 12, etc. are arranged on the copper foil pattern by soldering or the like. Also, on the circuit board 10 (on the surface opposite to the liquid crystal panel 2), zebra-shaped conductive rubber 18 and 19 are provided as switches.
Select electrode and positive electrode extended by MOSIC,
Button 2 of the external operation member, which will be described later, is arranged so as to straddle the set electrode and the positive electrode, respectively.
The well-known switching operation of select and set for adjusting the display time can be performed by touching and separating the 0.21. On the other hand, the relationship between the movement and the outer case is such that the display surface of the display panel is as wide as possible, and the wall thickness of the outer case is as narrow as possible.In order to obtain a watch with a smart design and high design flexibility, the outer case is A panel frame 25 made of plastic is incorporated into the body 24 of the case that holds the glass 22 and the waterproof ring 23 as a guide for the liquid crystal panel and as an interference member in the event of an impact. The above-described liquid crystal panel 2, connectors 8 and 9, circuit blocks, etc. are assembled, and then the movement is made of plastic material and given a name, a circuit receiver 26 having a springy part 26a is arranged around the outer circumference of the movement, and a back cover is installed. 27 pushes up the spring portion 26a of the circuit holder and the circuit board 9 to fix the movement. Note that on the back lid 27, the buttons 20 and 21 of the external operating members described above are mounted on a pipe 28, a button 29, and a button 29, which are fixed to the back lid by brazing.
Button ring 3 for determining ring-shaped button degree
As shown in the figure, the buttons 20 and 21 are constructed to such a size that the heads of the buttons 20 and 21 do not protrude from the bottom surface of the back cover.

Next, the liquid crystal panel will be explained in detail.

FIG. 7 is an explanatory diagram of segments of the liquid crystal panel in the timepiece shown in FIGS. 1 and 3. FIG. 8 is an explanatory diagram of the segments of the liquid crystal panels in the watches shown in FIGS. 2 and 4. Although the two liquid crystal panels have extremely different display characters 2a relative to the outer shape of the panel glass in the vertical and horizontal directions, First, wiring is done so that the positional relationship of the circuit block coupling terminals 2b to each display segment 2a is the same. In this way, by wiring the liquid crystal panel and the circuit block, it is possible to arrange liquid crystal panels having display characters of various designs that match the needs of the watch case design, as long as the positions of the coupling terminals can be kept constant.

In the explanations so far, we have assumed that the ranges with different LCD panels are the same movement, but even now, especially in fashion-oriented watches, when the color tone of the liquid crystal or the color tone of the polarizing plate is different, or the displayed text is different. Even if the fonts are different, they are treated as the same movement, and there are almost no problems with the processing.

FIGS. 9 and 10 are plan views of timepieces according to other embodiments of the present invention, and like the previous embodiments, both are timepieces designed with the same movement. This is because when placing the external operating member on the back cover poses a problem with operability as in the above embodiment, for example, by operating the external operating member against the normal time display on the display, This is very effective for watches that display month/day or seconds.

FIG. 11 is a partial plan view of the movement in the timepiece of FIGS. 9 and 10, which also has zebra-shaped conductors 31, 32, and
33.34 to external operating members 35.36 and 37.
By arranging them at positions corresponding to 38, switching operations can be performed by operating the buttons of each model. Of course, this conductive rubber is 31, 32 and 10 for the watch shown in Figure 9.
For the clock shown in the figure, only 33 and 34 need to be incorporated, and basically, by arranging multiple parts for each function button in the movement for button switching operation, It becomes possible to use the same movement.

Although the above embodiments have all been described using a liquid crystal panel as a display, the invention is not limited to this, and the same applies to any digital display.

As described above, according to the present invention, the liquid crystal panel and the circuit board are made into almost the same rectangular shape, the batteries are arranged inside the outer periphery of the liquid crystal panel, and one of the pair of electrodes serving as terminals with the same function is connected to the circuit board. One button is placed on the short side of the board and the other on the long side, so even if the button position relative to the case is different,
In addition, even if the button position relative to the case is the same, a common movement can be used even if the longitudinal direction of the LCD panel is parallel or perpendicular to the band, reducing costs and increasing product variety. It is something. In addition, the liquid crystal panel and circuit board are fixed by placing each component in a recess in the outer body and fixing the back cover, so the combination of the liquid crystal panel, module (movement), and case is easy. It is easy to make and has the advantage of allowing retailers to select designs according to their tastes.
