Description

[Detailed description of the invention] This invention is an indicator device installed in electrical equipment such as a television receiver or a composite device that combines this with a radio receiver, etc. This is related to indicator devices such as the channel selection display on the machine.Especially when downsizing electrical equipment, it is necessary to effectively utilize the space, in other words, to skillfully separate the part where the speaker or microphone is installed and the part where the indicator is installed. In combination,
The installation space for both of these components is minimized, and the space is effectively utilized to make the electrical equipment as small as possible.

In conventional electrical equipment, electroacoustic transducers such as speakers and microphones and indicators were installed in separate locations, which naturally required a large installation space. However, in recent years, with the miniaturization of electrical equipment and the emergence of the above-mentioned composite equipment, there has been an increasing need to effectively utilize space and downsize electrical equipment as much as possible. .

This invention was devised in view of such needs, and the indicator device will be explained below with reference to the embodiments shown in the figures.

Fig. 1 is a front view showing a part of the front of a television receiver equipped with the indicator device of this invention, Fig. 2 is a side sectional view thereof, and Fig. 3 shows some of its constituent parts. FIG.

In the figure, reference numeral 1 denotes a panel, and this panel 1 is provided with a circular opening 2, and on the outer periphery of the circular opening 2, there are channel numbers or scales for VHF television broadcasting and UHF television broadcasting. A display section 3 displaying the following information is attached. Reference numeral 4 denotes an annular body rotatably attached along the inner periphery of the circular opening 2, and this annular body 4 is provided with an index 5 for indicating the display section 3 described above. Further, a shaft 6 is disposed at the rear center of this annular body 4, and is fitted into a center hole 8 of a holding body 7 attached to the rear thereof, thereby forming a shaft bearing part and rotating the annular body 4. It is free to move. The shaft 6 is formed integrally with a gear 9 fitted on the outer periphery of the annular body 4, and is provided with a space 10 similar to the holder 7 shown in FIG. 3. Reference numeral 11 denotes a speaker, which is provided at the rear of the holder 7, or in other words, is arranged to face the circular opening 2. 1
Reference numeral 2 denotes a mesh made of wire mesh or the like to cover the opening of the circular opening 2, and is used to prevent damage to the speaker 11 and to improve its appearance.

A small hole 13 is provided on the side of the circular opening 2 of the panel 1, and a shaft 15 (rotating member) of a variable resistor 14 for channel selection is provided in the small hole 13. This variable resistor 14 is connected to the speaker 11.
A gear 17 is attached to the shaft 15 by press fitting or the like.
It is set in.

This gear 17 and the gear 9 provided on the outer periphery of the annular body 4 are meshed with each other via a two-stage gear 18, as shown in FIGS. 2 and 3.

Therefore, since the transmission member consisting of the gear 9, the two-stage gear 18, and the gear 17 is inserted between the annular body 4 and the shaft 15 of the variable resistor 14, the shaft 15 of the variable resistor 14 By rotating in an arbitrary direction, the annular body 4 is rotated by these gears in the same direction as the rotation direction of the shaft 15 of the variable resistor 14, and the indicator 5 causes the display unit 3 to be rotated. Specify any channel number (or scale, etc.).

The electronic tuning tuner of the tuning mechanism has variable resistor 1.
By rotating 4, the voltage can be varied and applied to the variable capacitance diode, and the desired frequency tuning can be obtained, and this is displayed on the display section by determining the rotation angle for each channel. This is variable resistor 1
Channel selection is possible by combining a plurality of gears with rotation angles and rotation ratios of 4.

The sound from the speaker 11 is transmitted to the space 1 of the holder 7.
0, etc., and is sent out to the outside from the net 12 fitted to the annular body 4 without any hindrance.

The embodiment described above is a channel indicator device for a television receiver, but it goes without saying that this invention can also be applied to display tuning of a radio receiver. However, instead of this speaker, a microphone or a microphone that also serves as a speaker may be used.

As described above, this invention consists of a circular opening provided in a panel with display parts such as numbers or scales attached to the outer periphery, and an indicator, which is attached rotatably along the inner periphery of the circular opening. an annular body, an electroacoustic transducer such as a speaker disposed opposite to and behind the circular opening, a rotating member provided on a side of the circular opening, and a rotation of the rotating member. The indicator device consists of a transmission member inserted between the annular body and the rotating member in order to rotate the annular body according to the movement of the annular body, so it is suitable for electroacoustic transducers such as speakers and microphones. The mounting part and the indicator mounting part are skillfully combined to minimize the installation space for both, making effective use of the space, making it extremely advantageous when downsizing or combining electrical equipment. In addition, since the circular opening for speakers, microphones, etc. is used and an indicator section is provided around it, the front display section can be displayed without taking up space, and the appearance is also good. Furthermore, since the circular opening is not blocked by channel selection knobs, etc., it has features such as good acoustics.
