Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for an analog clock inside a lighting lamp, which is installed independently in the interior of a vehicle, for example.

In a conventional analog watch of this kind, for example, as shown in FIG. A lamp lighting circuit board 4 is attached to the outside of the protective cover 3, and an illumination lamp 5 is attached to the substrate 4 via a socket 6. Further, a receiving plate 8 of the dial 7 is attached to the front surface of the protective cover 3 via mounting screws 9, and the peripheral edge of this receiving plate 8 is sandwiched between the outer case 10 and the front cover 11. Moreover, they are integrally fixed by mounting screws 12. 13 is a circuit board located inside the protective cover 3 and for driving the movement; 14 is a minute hand 15;
This is a correction knob. In this way, in conventional analog watches, the circuit board 13 for driving the movement and the circuit board 4 for lighting the lamp are constructed from separate members, and they each use mounting parts at separate locations. Furthermore, the dial 7 is fixed and held by the support plate 8, which not only increases the number of parts but also increases the number of assembly steps. The product cost is high, and the receiving plate 8 impairs the illumination level of the dial 7.

The present invention was devised to solve these problems, and in particular, by using a single circuit board instead of the two circuit boards shown in the conventional example, the number of parts and assembly man-hours can be significantly reduced. It is an object of the present invention to provide a mounting device for an analog watch that can reduce the product cost.

The present invention will be explained in detail below based on the embodiment shown in FIG.

21 is a movement of a watch 22, and this movement 21 is housed in a protective cover 23, and this protective cover 23 has mounting legs 2.
4 are integrally formed. Reference numeral 25 denotes an exterior case that houses the protective cover 23 that houses the movement 21, and the exterior case 25 and the mounting legs 24 of the protective cover 23 are connected to the mounting screws 2.
6 so that it can be fixed. 27 is a printed wiring board attached to the movement 21, and this printed wiring board holds an electronic component 28 for driving the movement 21 and a socket 30 for an illumination bulb 29. 31
is a dial plate located on the front side of the movement 21, and the periphery of this dial plate 31 is the outer case 2.
5, the front cover 32 is held by a mounting means such as a snap fit. Reference numeral 33 indicates an hour and minute adjustment knob held through the center of the front cover 32, and reference numeral 34 indicates a minute hand.

The above is the configuration of this embodiment. Since the movement 21 in this embodiment is fixed to the back surface of the outer case 25 via the protective cover 23 with the mounting screws 26, the receiving plate 8 described in the conventional example can be omitted. Therefore, the degree of transmitted illumination of the dial 7 caused by the receiving plate 8 is not impaired, and the dial 31 in this embodiment is effectively transmitted illuminated by lighting the illumination bulb placed behind it. . Furthermore, in the conventional example, the movement mounting screws 9 appear on the front of the dial 7, but in this embodiment, the movement mounting screws are located at the back, so the design effect of the dial may be lost. It can be resolved. Furthermore, in this embodiment, since the single printed wiring board 27 serves as both the circuit board for driving the movement and the circuit board for lighting the light bulb, the number of parts and the installation process can be reduced.

As described above, in the present invention, the circuit board 27 for driving the movement 21 is positioned and fixed on the outside of the protective cover 23 to the movement 21 housed and protected within the protective cover 23, and the movement 21 is mounted on the exterior. A light source 29 that is housed in the case 25 and attached to the rear of the outer case 25 and that illuminates the dial 31 is attached to the circuit board 27 and is detachable from the rear of the outer case 25. Since this is a mounting device for an analog watch, the movement drive circuit and the lighting circuit for the light source 29 are configured on one circuit board 27, so the two circuit boards shown in the conventional example can be combined into one circuit. As a result, the number of circuit boards and the parts to which the circuit boards are attached can be reduced, and the number of man-hours required to attach the circuit boards can also be reduced, resulting in a significant reduction in product costs. Furthermore, according to the present invention, the movement mounting screws are located behind the protective cover and the outer case, and are not located on the surface of the dial as shown in the conventional example, which hinders the design effect of the dial. It has some unique features.
