Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dial plate having a plurality of mounting holes for mounting and having dial display parts such as dial numbers printed on the surface thereof.

Traditionally, various instruments, transistor radios,
A dial plate having the above-mentioned configuration used in a stereo tuner or the like is made of, for example, a rectangular aluminum plate, and dial numbers for appropriately indicating frequencies are printed on the aluminum plate. However, it is extremely difficult to print dial numbers and the like in correct positions according to the predetermined shape of the aluminum plate. For example, when dial numbers, etc. are printed on an aluminum base plate, and then the aluminum base plate is die-cut into a predetermined shape, the above printing and the above die-cutting tend to cause vertical, horizontal, and angular misalignment with respect to each other. . Further, even if such a deviation occurs, it is difficult to confirm whether it is within an allowable range or not, and the assembly is often carried out without noticing the above-mentioned deviation. Such deviations are often discovered only when the indicator line does not match the reference frequency of the dial plate when the instrument is tuned to the reference frequency during the inspection of the final product. Moreover, such defective products must be disassembled and a new dial plate installed, which requires extra effort and is extremely troublesome.

The present invention aims to solve these problems, and has a plurality of mounting holes on the periphery for mounting with screws, etc., and a dial display part is printed on the surface. In the dial plate, a narrow positional deviation detection part that can detect a relative positional deviation of the mounting hole with respect to the dial display part, but cannot substantially detect angular deviation by itself, detects the printing of the dial display part. are formed along the edges of at least two of the mounting holes by printing in a printing process simultaneously with the above, and these at least two positional deviation detection parts detect the position of the mounting holes relative to the dial display part. The present invention is characterized in that it is configured such that both relative positional deviation and angular deviation can be detected. Therefore, according to the present invention, it is possible to check at a glance the vertical deviation, horizontal deviation, and angular deviation between the shape of the dial plate and the dial display part that occur due to die cutting, etc., so that defects can be detected before assembly. The dial plate can be removed and the above problems are solved.

Next, embodiments of the present invention will be described with reference to the drawings.

This embodiment shows the dial plate 1 of the stereo tuner.
This dial plate 1 is made of a rectangular aluminum plate, and display parts 2 and 3 consisting of lines and numbers representing the AM and FM frequencies are printed in the center. It is formed by Two circular lines 4 are printed on the upper and lower sides of the dial plate 1 on the right side, and the positional deviation (eccentricity) thereof can be detected with respect to the two circular mounting holes 5 formed by die cutting. There is. Furthermore, on the left side of the dial plate 1, two approximately oval lines 6 are printed on the upper and lower sides, and the positional deviation (eccentricity) of the line with respect to the adjustable oval mounting hole 7 formed by die cutting is detected. It is configured so that it can be done. Therefore, when the four mounting holes 5 and 7 are misaligned with respect to the display parts 2 and 3, these mounting holes 5 and 7 are correctly positioned in the center of the circular line 4 or the approximately oval line 6. It doesn't fit, shifts or protrudes. By checking at least two mounting holes 5 and 7 for misalignment or protrusion, you can check at a glance for vertical misalignment, horizontal misalignment, and angular misalignment between the shape of the dial plate and the dial display section. can do. For this reason, defects in die cutting can be easily recognized with the naked eye, and defective parts are not assembled as they are, and it is possible to appropriately correct and use them, or to compensate for deviations in the mounting position. You can also throw away items that are too far out of alignment to be usable.

Although the present invention has been described above with reference to embodiments, it goes without saying that these embodiments do not limit the scope of the present invention, and that modifications can be made based on the technical idea of the present invention.

Since the present invention has the above-described configuration, even if the dial display portion is printed on a dial plate formed in advance by die cutting or the like so that it is vertically misaligned, horizontally misaligned, or angularly misaligned, In addition, even if the molding process such as die cutting after the dial display part is printed causes vertical deviations, horizontal deviations, or angular deviations, these can be detected by simply looking at the periphery of the mounting hole of the dial plate before assembly. Since deviations can be detected and are not detected only by inspecting the final product as in the past, it is possible to reduce the defective rate of products incorporating the dial plate.

In addition, the positional deviation detecting section of each strip is formed along the edge of the mounting hole provided on the peripheral edge of the dial plate and for mounting with screws, etc. It is possible to detect relative positional deviations, but angular deviations cannot be detected by itself, so there is no need to make the positional deviation detection part of the thin cloth into any special shape. , it is possible to make it less noticeable than necessary, and even if the mounting hole for mounting with screws etc. is a small hole, the above-mentioned positional deviation can be accurately confirmed, and as a result,
Even if the mounting hole is a small hole, angular deviation can be accurately confirmed by at least two positional deviation detection parts.
