Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a timepiece.

[0002]

2. Description of the Related Art A fixed structure of a timepiece display panel (for example, a liquid crystal display element, an electroluminescence display element, and an electrochromic display element) of a timepiece includes a seat for receiving a lower surface of the timepiece display panel and an upper surface of the timepiece display panel. It has a flange arranged oppositely, and one of the flanges is formed on a hook, and by bending this, a structure for incorporating a watch display panel from a clock viewing direction, and a structure of a display panel fixing frame. There is a structure in which the watch display panel is dropped from the back cover side and incorporated.

FIG. 1 is a sectional view of a timepiece module according to the prior art. The clock module includes a display panel fixing frame 1, a clock display panel 2, a circuit board 3, a battery 4, conductive rubber 6,
It is composed of a battery holding plate 7, fixing screws 5, and the like. The display panel fixed frame 1 has a fixed frame hook portion 1a, a movable hook 1
b, a fixed flange 1c and a seat 1d are formed. In this structure, the watch display panel 2 is dropped by bending the movable hook 1b on the display panel fixing frame hook 1a from the viewing direction, and the movable hook 1b, the fixed flange 1c, and the base 1d of the display panel fixing frame 1 are bent. The clock display panel is fixed vertically.

FIG. 2 is a sectional view of another timepiece module according to the prior art. The components are the same as those in FIG. 1, but the display panel fixing frame 11 has a fixing frame hole 11 a and a fixing flange 11.
b, 11c are formed. In this structure, the timepiece display panel 2 is inserted into the display panel fixing frame hole 11a from the circuit board 3 side.

[0005]

The structure shown in FIG. 1 has a seat 1d having functions of preventing the conductive rubber 6 from falling down, fixing the timepiece display panel 2 in the vertical direction, and preventing the circuit board 3 from bending.
Can be formed on a part of the display panel fixing frame 1, but it is difficult to assemble if the watch display panel fixing hook 1a is strong in strength, and it is easy to assemble if the strength is weak, but the watch display panel is easily detached. There is a problem.

[0006] The structure shown in FIG.
Since d cannot be formed, the conductive rubber 6 is likely to fall down until the timepiece module is completed, and the timepiece display panel 2 is not fixed in the vertical direction, so that there is a difficulty in assembling work.
When the circuit board 3 is pushed from the battery 4 or the like at the time of completion of the module, the circuit board 3 is bent because there is no seat 1d, and the watch display panel 2 and the potting resin 3a covering the IC
There is a possibility that a dent or the like may occur on the watch display panel 2 due to collision. The present invention is directed to a timepiece having a seat for preventing the conductive rubber from falling down, positioning the watch display panel downward, and preventing the circuit board from bending while having a strong fixing flange for fixing the display panel for the watch on the display panel fixing frame. The purpose is to get.

[0007]

Means for Solving the Problems A display provided with a plurality of opposing flange portions on a watch display panel for holding at least an upper end portion of the watch display panel and an insertion port for horizontally inserting the watch display panel from the lateral direction. The watch has a panel fixing frame.

There is provided a panel stopper for positioning the timepiece display panel in the lateral direction after being inserted into the panel frame. Further, a hook for preventing the panel from coming off in the direction of the insertion port is provided in the clock display panel insertion port of the display panel fixing frame.

[0009]

FIG. 3 is a top view, a front sectional view, and a side sectional view of a module structure of a wristwatch having a liquid crystal display device according to an embodiment of the present invention. In FIG. 1, only the display panel fixing frame 12 and the liquid crystal display element 10 are displayed. The display panel fixing frame 12 has a concave portion for positioning the liquid crystal display element 10 in the vertical direction (the direction of the arrow in the drawing) and a fixing flange 12 for positioning the liquid crystal display element 10 in the vertical direction.
b, 12c and a pedestal portion 12d are formed, and a display panel insertion opening 9 for slidingly housing the liquid crystal display element 10 from the lateral direction (the direction of the arrow in the figure) is formed.

The liquid crystal display element 10 is housed in the display panel fixing frame 12 by moving horizontally between the fixed flanges 12b, 12c and the seat base 12d from the liquid crystal display element insertion slot 9 in the horizontal direction. As shown in FIG. 3, a panel stopper 1 which is a wall or a flange for positioning a side of the liquid crystal display element 10 in the 3 o'clock direction.
2a is formed on the display panel fixing frame 12, and the liquid crystal display element 1
It is preferable to adopt a structure in which the positioning is carried out when the O is inserted until the O contacts the panel stopper.

The liquid crystal display element 1 is provided in the panel insertion port 9.
0 The liquid crystal display element detachment prevention hook 8 for preventing the liquid crystal display element 10 from shifting to the opposite side to the arrow in the figure after storage.
Is preferably provided. Liquid crystal display element detachment prevention hook 8
Is used for temporary fixing, and final fixing is performed by pressing the fixing flanges 12b and 12c of the display panel fixing frame 12 with conductive rubber after the module is assembled.

[0012]

As described above, since there is no structure for fixing the timepiece display panel to the display panel fixing frame by the movable hook, the fixing strength of the display panel fixing frame in the vertical direction can be increased.

[0013] By inserting the clock display panel into the display panel fixing frame from the lateral direction, the structure of the display panel fixing frame has one of the upper and lower surfaces of the clock display panel mounting space for mounting the clock display panel. There is no structural restriction for incorporation that the direction is open. In this manner, the display panel fixing frame forms a fixing flange for firmly fixing the timepiece display panel, and a pedestal having functions of preventing fall of the conductive rubber, positioning of the timepiece display panel in the vertical direction, and preventing bending of the substrate. Can be.
