Description

[Detailed explanation of the idea] The present invention relates to a dial mechanism for audio equipment, etc.

Conventionally, frequency display sections of audio equipment and the like have been placed at the front center or on the top surface of the set body due to the purpose of use and design. On the other hand, the tuning knob has been placed on one side or side of the set body for ease of operation. For this reason, the dial mechanism section, including the tuning mechanism section and the frequency display section, occupies a large space in the set body and overlaps with other parts, causing problems in workability when assembling the main body set or replacing parts for repairs. It was hot. Furthermore, when the frequency display section position is different due to a set of different sizes of the main body or a design change, it is necessary to design and form a new dial mechanism section. By the way, as a device that can adjust the positional relationship between the tuning operation axis and the pointer, there is
A technique disclosed in Publication No. 55-15056 is known, but this technique corrects the discrepancy between the display of the dial pointer and the content of the received frequency, etc.
It was not possible to solve the above-mentioned problems.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a dial mechanism that eliminates the above-mentioned drawbacks.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the first board, FIG. 2 is a diagram showing the second board, and FIG. 3 is a diagram showing the first board attached to the second board. In FIGS. 1 and 2, 1 is a first substrate made of synthetic resin, etc., 2a, 2b, 2
c is a dial rope guide pulley installed on the first substrate 1, 3 is a dial pointer guide rib integrally molded with the first substrate 1, 4 is a fixing screw mounting hole of the first substrate 1, and 5 is the first A locking part integrally molded with the substrate 1, 6 a second substrate, 7a and 7b a second substrate 6
Dial rope guide pulley installed in 8
9 is a long hole into which the locking part 5 of the first board 1 is inserted;
Numerals a and 9b are mounting holes for fixing screws of the first substrate 1 provided on the second substrate 6, numeral 10 is a tuning shaft provided on the second substrate 6, and numeral 11 is formed integrally with the second substrate 6. The dial rope guide rib 12 is a through hole for mounting a drum that drives a tuned variable capacitor. 1st
As shown in FIG. 3, the substrate 1 and the second substrate 6 are attached by inserting the locking portion 5 of the first substrate 1 into the elongated hole 8 of the second substrate 6 and fitting the locking portion 5. FIG. 4 is a diagram showing a state in which the first board 1 is fixed by the fixing screws 9c at the positions of the first board 1 fixing screw attachment holes 9a of the second board 6. Normally, in this state, tuning axis 1
The dial pointer 15 is slid through the drum 14 by rotating the tuning knob 13 fitted to the dial 14, thereby performing a dial tuning operation. However, in the past, parts that overlapped the first board 1 had to be assembled before assembling the dial mechanism, and when replacing parts, it was necessary to remove the dial mechanism beforehand. According to the method, as shown in FIG. 5, by removing the screws 9c for fixing the first substrate 1 and sliding the first substrate 1 along the elongated holes 8 of the second substrate 6, the portion overlapping the first substrate 1 is removed. The parts can be easily assembled and replaced without removing the dial mechanism. Also, if the size of the main body case is small or if the dial display section is close to the dial tuning mechanism section, for example, the first board 1 shown in FIG.
If the first board 1 is fixed with a screw at the position of the fixing screw attachment hole 9b, the same dial mechanism parts can be used in common. In addition, the fixing screw mounting hole 9a,
The same dial mechanism can be used in many types of audio equipment by providing a plurality of similar mounting holes between the dials 9b or by forming only the first board depending on the travel distance of the pointer.

As detailed above, according to the present invention, not only can the same dial mechanism be commonly used for a set of multiple models with different frequency display positions, but also
When assembling and replacing parts located behind the first board,
The work can be easily carried out by simply moving the first substrate in the direction in which it overlaps with the second substrate.
