Description

[Detailed Description of the Invention] The present invention relates to a dial display device used in radio receivers and other equipment, and the object thereof is to provide an excellent display device with a simple configuration.

Generally used dial display devices have a dial lobe suspended between a dial drum attached to the rotating shaft of the variable capacitor and a separate pulley, and a pointer is attached directly to this dial lobe so that the pointer can be seen through the display window. Many of them are composed of

However, this type of device requires a separate dial drum, pulley, dial lobe, etc.

Furthermore, there was a problem in that a considerable amount of work was required to suspend the dial lobe.

On the other hand, it is also known that a drum is attached directly to the rotating shaft of the variable capacitor and display characters are drawn on the side of the drum so that the display characters can be seen through the display window. The problem is that the size of the display itself is determined by the size of the display, making it impossible to display a large display.

This proposal eliminates the above-mentioned conventional drawbacks,
To provide an excellent dial display device that has a simple configuration and can display a relatively large display.

Hereinafter, five proposed dial display devices will be described with reference to drawings of one embodiment.

In the figure, 1 denotes a cabinet 22, a display window formed on the front panel of the cabinet 1, 3 denotes a mounting plate for the chassis, printed wiring board, and other components housed in the cabinet 1, and 4 denotes an operating shaft 5 formed on the above-mentioned mounting plate 3. is inserted into the through hole 6.

Variable capacitor 8 is attached to the mounting plate 3 by screws 7.7, 8 is a drum whose fitting hole 9 formed in the center of the side is fitted into the operating shaft 5 of the variable capacitor 4, and 10 is the drum 8. A bottle protruding from the side.

Reference numeral 11 indicates a display plate having a rotary shaft portion 13 inserted into a through hole 12 formed in the mounting plate 3 at one end and pivotally attached thereto, and a long hole 14 at the other end, and reference line 15 drawn on the display plate 11. +16
．． Reference numeral 17 denotes a washer and a screw for pivotally attaching the rotating shaft portion 13 of the display plate 110 to the mounting plate 3.

Note that the tip of the rotating shaft portion 13 of the display plate 110 is formed to have a small diameter, and the small diameter portion 13a is inserted into the through hole 12 and is pivotally attached by being tightened with a screw 17 via a washer 16.

Further, display symbols or display characters 18 are drawn in the vicinity of the display window 2, respectively.

In the above embodiment, the variable capacitor 4 is attached to the mounting plate 3,
After attaching the drum 8 to the rotary shaft 5 of the variable condenser 40, the display plate 11 is pivoted to the mounting plate 3, and the elongated hole 1 formed in the display plate 11 is
If you insert bottle 10 into 4.

The result is as shown in FIG.

゛Therefore, the assembly assembled in this way is
As shown in the figure, if the table board 11 is housed in the cabinet 1 so as to face the display window 2, and a part of the circumference of the drum 80 rows is made to protrude from the through hole 19 formed in the side surface of the cabinet 1, The completed dial display device is constructed as shown in FIG.

As described above, the above embodiment has the advantage of being simple in structure and extremely easy to assemble.

Then, in the completed dial display device, the through hole 1
When the drum 8 protruding from the drum 9 is driven to rotate in the direction of arrow A in FIG. Since the dial is rotated in the direction of the arrow in FIG. 3 around the center, the position of the indicator line 15 that can be seen through the display window 2 changes sequentially as shown in FIGS. 3 to 5, resulting in accurate dial display. can be done.

As is clear from the above embodiments, the dial display device according to the present invention can provide a unique and accurate display with a simple configuration, and is extremely advantageous in practice.

In the embodiment, the drum 8 is provided with a bottle 10 and the display board 11 is provided with a long hole 14, but it goes without saying that the drum may be provided with a long hole and the display board may be provided with a bottle. .
