[Prior Art]

 Conventional watch dials have a single board with surface treatments such as patterning, plating, painting, and printing. In addition, time display and decorative accessory parts are assembled to diversify the watch design and enhance the level of decorative effect. I came up for it. However, as the clock function has become more sophisticated in recent years, in addition to the conventional pointers for indicating the time and seconds, a clock for indicating 1 / 100th of a second, day, day, month, etc. by the pointer, and a clock. The design has become very popular. Ergonomics indicates that the marking and decoration around the rotation center of the pointer are the most natural to make it easier to read when the pointer is rotated to indicate the necessary items. As a result, it has become indispensable to combine a large number of needle rotation centers on the dial surface with markings and decorative finish at the rotation center. However, in order to manufacture these dials by the above-mentioned conventional method, it is necessary to add processing to one raw material that requires the number of processing times corresponding to the number of rotation centers, and the rotation center is arranged at the position where the pointer rotation center is arranged. Combined rotary processing has been added, and it has been necessary to devise processing jigs, processing holders, etc. so as not to impair the processing accuracy and aesthetics of the finished product. Also, these difficulties have created design constraints that have hindered the development of new designs. To solve such a problem, a combination of a dial main body and an upper plate manufactured separately from the main body as in JP-A-51-136447, JP-A-52-10759, and JP-B-61-24947 is solved. It can be understood that the measures are effective, but all of these proposals have different purposes, and are not necessarily effective for producing the dial plate of the multi-rotation center design as described above. In each of the proposals, the time marking piece was implanted in the dial main body, and the upper plate was subjected to the surface treatment only after the time stamping piece was released and punched, and then fixed on the main body to reduce the total thickness of the dial. It was trying to respond to the expansion of design variety while suppressing it. In other words, the thick marking piece is fixed to the main body, the surface finish is processed into the upper plate, and both are integrated to try to satisfy the appearance and functional quality of the dial.

[Problems to be solved by the device]

 As shown in FIG. 1, in the case of a dial for a multi-function, multi-hand watch, a conventional integrated dial, as shown in FIG. 1, the dial base 1 has a base pattern 4, and the auxiliary pointer rotating parts 9 and 10 are different from the base, respectively. The pattern a and the pattern b are formed, subjected to surface treatment such as plating, painting and printing, and the marking piece 2 and the auxiliary pointer rotating portion marking piece 7 are fixed to each other. Furthermore, in order to give a three-dimensional effect to the auxiliary pointer rotating part, as shown in FIG. 2, the auxiliary pointer rotating part is subjected to cutting processing centering on the center of rotation of the pointer and at the same time the ground slope 11 is formed. There is also. Although the method shown in FIG. 1 is relatively simple, resist processing is required to provide contrast between the base portion and the auxiliary pointer rotating portion, and the durability of the resist coating limits the finish that can be processed. In addition, according to the method shown in FIG. 2, a clear contrast can be expressed in the base portion and the auxiliary pointer rotating portion, which is a process of cutting, which can produce an attractive dial with a three-dimensional effect. Firstly, there are drawbacks in that the processing scratches on the dial surface during the processing must be prevented, and secondly, the thickness of the base plate of the pointer rotating portion is reduced by cutting. In any case, incidental work such as resist coating and removal after processing is required.In the latter case, the cutting depth, cutting tools, jigs and tools to ensure the aesthetics of the cutting boundary slope are further devised. It was In other words, in the design that two or more dials coexist in a single dial in terms of area ratio, the above problems were encountered. As described above, the present problems are proposed in the above-mentioned JP-A-51-136447, JP-B-52-10759, and JP-B-61-24947. The success of the method, such as simply providing an opening through which the indication part for the pointer or a part of the finish can be seen, is unsuccessful, and the solution was first seen by the present invention.

In order to solve the above-mentioned drawbacks, the present invention applies the finishing of the auxiliary pointer rotating portion to the dial main body, and finishes the rotating portion of the hour, minute main pointer or the hour, minute, second main pointer. In regards to the above, it is processed separately as an upper plate, and then the main body and the upper plate are fixed by adhesion, riveting, or welding.

The object of the present invention is to overcome the drawbacks of the above-mentioned conventional methods, improve the efficiency of the production of dials, and respond to the expansion of the design variety of dials. is there.

[0010]

According to the first embodiment of the present invention, two auxiliary pointer rotating parts on the dial main body are subjected to different surface treatments and pointer displays, respectively, to provide contrast, and then the upper plate. A surface treatment different from these appearances and indication for pointers were performed on the surface, and it was possible to give a triple contrast. Furthermore, a beveled mirror surface cut with a diamond cutting tool was used to create a valuable impact on the design at the opening edge for the upper plate pointer. In the conventional method as shown in Fig. 2, it is unavoidable to grind the auxiliary pointer rotating part to a certain depth and to insert a bevel cut with a diamond cutting tool at the edge, which will inevitably increase the plate thickness of the base material. The required thickness has reached 0.8 mm, which is a significant disadvantage now that thin watches have become commonplace. The second embodiment is an embodiment designed and implemented for a thin timepiece, in which quadruple contrast can be obtained, and at the same time, by applying a thin marking piece for the upper plate, the thickness can be reduced by about 20% of the conventional thickness. Came out. In the third embodiment, since the main pointer rotating part and the auxiliary pointer rotating part are each in a semi-finished state as separate parts, and a final dial is assembled into a single dial, the method is adopted. Masking by resist processing is no longer necessary, and three types of parts can be processed in parallel, leading to a reduction in total processing lead time. Furthermore, by standardizing the dimensions of each part, it is now possible to stock various types of auxiliary pointer rotating part finished parts as semi-finished products, and it has been possible to shorten the delivery time for the design and processing of various small-quantity products.

In summary, according to the present invention, the dial plate is divided into two parts, the main body and the upper plate, which are processed with equal specific gravities and then combined, whereby first, the design variety of the dial plate is dramatically improved. It brought about expansion. Second, it contributes to the total improvement of product quality by avoiding the risk of repeatedly applying to the same part the machining that may damage the surface once finished, such as cutting or masking. It was possible. Thirdly, by reducing the frequency of masking processing, processing efficiency could be increased by about 15% compared to the conventional method. Fourthly, the method of stocking each rotating part of the pointer as a separate semi-finished product has shortened the delivery time of design and production.
