ないという欠点があつた。 Conventionally, when making a watch module smaller, there are cases where it is not possible to install the extrusion part using the ejector pin during injection molding of the injection molded parts that make up the watch module.In such cases, it is necessary to make the injection molded parts larger and make the watch module larger. The drawback was that it had to be dealt with either by reducing the size of the parts other than the injection molded parts that make up the wristwatch module, such as the battery or the liquid crystal panel.

を防止することをも目的としたものである。 The present invention eliminates these drawbacks and makes the watch module as small as possible by providing a protrusion on the outer periphery of the injection molded parts that make up the wristwatch module. By providing a tightening allowance, the purpose is to prevent rattling between the watch module and the watch case when the watch module is assembled into the watch case.

のがたつきを防止できるわけである。 Next, we will take a panel frame as an example of an embodiment of the present invention.
To explain this with reference to the drawings, conventionally, when making a wristwatch module smaller and increasing the size of the liquid crystal panel, a method has been used in which the substrate and panel frame are integrated by heat staking. However, even with this method, it may not be possible to install an extrusion portion using an ejector pin during injection molding of an injection molded part such as a panel frame.
In such a case, you must either make the watch module larger or reduce the size of the LCD panel. Therefore, on the outer periphery of the panel frame 1, a protrusion 2 is provided that contacts the inner periphery of the wristwatch case with a tightness margin.
By using the watch module as an extrusion part using an ejector pin during injection molding, the watch module can be made as small as possible, and when the watch module is assembled into a watch case, it is possible to prevent rattling between the two. That's why.

りと組み込めると言う効果を有する。 As described above, by providing a protrusion on the outer periphery of the injection molded part constituting the wristwatch module according to the present invention, the protrusion part can be attached to the ejector pin during injection molding of the injection molded part constituting the wristwatch module. In addition, when the watch module is assembled into a watch case, the protrusions provided at three or more locations on the side surfaces of the maximum outer diameter of the injection molded part engage with the inner wall of the watch case with a tight fit. It has the effect that it can be firmly assembled into the watch case without any wobbling due to deformation.
