Abstract

PURPOSE:To change a radio band received depending on a location placed with a radio set by providing a scale plate and a tuning variable resistor at each radio band to each face of a polygonal prism and providing a band switch turning on/off a power supply at each radio band to a face different from the face of radio bands. CONSTITUTION:When the radio set is placed on a horizontal face at a location possible for an FM band, an FM band switch 10 is turned on, the FM band is in received state, an FM broadcast is received by adjusting an FM tuning variable resistor 4 while observing the FM scale plate 5 and an FM sound volume 3 adjusts properly the sound volume from a speaker 6. In replacing the radio set to a position at which an MW band is viewed, an MW band changeover switch 15 is turned on while being contacting a horizontal face, an MW band is received and a desired broadcast on the MW band is listened to the same as the FM band. The band switch turning on/off the power supply of each radio band is activated by placing the receiver on a horizontal face, and the activated radio band differs from the placed face, then it is not required to change over the band changeover switch when the radio band is changed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a radio receiver that can change the receiving radio band depending on how it is placed on a stand such as a desk or table.

BACKGROUND OF THE INVENTION In recent years, there has been a growing demand for fashionable radio receivers and cassette tape recorders with radio receivers, and products of varying shapes and colors have been produced. However, most radio receivers had a display on one side with operation switches, volume, and tuning controls on the adjacent side.

A conventional radio receiver will be described below with reference to the drawings. Figure 4 shows a conventional radio receiver.
19 is a band selection switch, 20 is a tuning volume, 21 is a volume volume, 22 is an earphone jack, 2
3 is a scale plate, 24 is a spinach 25 is a power switch.

In the radio receiver configured as described above, when the power switch 25 is turned on, the user selects the desired radio band with the reband selector switch 19 depending on the radio reception state, and tunes the broadcast station with the tuning volume 20 while looking at the scale plate 23. Select it, and receive the broadcast while adjusting the volume of the speaker 24 appropriately using the volume volume control 21. Band selection switch 1
9 is often used in common with the power switch 25.

Problems to be Solved by the Invention However, in the configuration as described above, there is a scale plate or a speaker in front of the user, and a switch, volume, jack, etc. is arranged on that side or on an adjacent side. There were so many cases that the receivers often looked very similar in design.

In view of the above-mentioned problems, the present invention has been designed to be different from conventional ones in terms of design, and provides a radio receiver in which when the receiver body is placed on a horizontal surface, the radio bands that can be received can be changed depending on the surface on which the receiver is placed. be.

Means for Solving the Problems In order to solve the above problems, the present invention provides a scale plate and a tuning volume for each radio band on each face of the polygonal prism, and further provides a 0N power supply for each radio band. −
This device has a configuration in which a band switch to be turned off is provided on a surface different from the surface of the corresponding radio band.

Effect of the present invention With the above-described configuration, for example, when a radio receiver is placed with one side facing down, the band switch on that side is turned on, and the corresponding radio band on the other side can be received. If you turn the other side down, the switch on that side will turn on and you will be able to receive the radio bands on the other side, making it possible to realize a radio receiver that can change the radio bands that can be received depending on the position where the radio receiver is placed.

Embodiments Hereinafter, radio receivers according to embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a radio receiver according to an embodiment of the present invention, with the FM band visible from the front. Figure 2 shows the position where the MW band can be seen from the front, Figure 3 shows the position of the S
This is a perspective view of each radio receiver placed in a position where the W band can be seen from the front.

In Figure 1, 1 is the FM band surface of one of the radio receivers where the FM radio band is installed, and 2 is the non-locking SW band switch that turns on when placed on a horizontal surface, turning on the SW band power.3 is FM volume volume, 4 is F
5 is an FM scale plate, 6 is a speaker, 7 is an earphone jack, and 8 is an antenna.

5. In Fig. 2, 9 is the MW band surface of one of the radio receivers into which the MW radio band is introduced, and 1o is the non-band surface that turns on the FM band when placed on a horizontal surface. FM band switch of lock, 11 is MW volume volume, 12 is MW detuning volume, 13 is MW scale plate.

In Fig. 3, 14 is one SW band surface of a radio receiver with a built-in SW radio band, 15 is a non-locking MW band switch that turns on when placed on a horizontal surface and turns on the MW band power, 16 17 is a SW detuning volume, and 18 is a SW scale plate.

, First, if the radio receiver of the embodiment is placed on a horizontal surface in a position where the FM band is visible as shown in Fig. 1, then the FM band shown in Fig. 2 is
The band switch 1o is turned on, the FM band is in the receiving state, and while looking at the FM scale plate 5, adjust the FM detuning volume 4 to receive the FM broadcast, and adjust the volume from the speaker 6 appropriately using the FM volume volume 3. adjust.

Next, as shown in Fig. 2, when the radio receiver is placed in a position where the MW band can be seen, it comes into contact with a horizontal surface and the MW band changeover switch 15 is turned on, and the MW band is received. Similarly, you can listen to desired broadcasts in the MW band.

If you want to receive the SW band at the same time, all you have to do is place the radio receiver in a position where you can see the SW band, as shown in Figure 3.

When the radio receiver does not need to be operated, the speaker 6,
If the side with the earphone jack 7 and antenna 8 or the opposite side is in contact with a horizontal surface, each band switch 2, 10, 15 is a long lock type, so none of the switches will be turned on and the radio receiver will turn on. It will not work as such.

As described above, according to this embodiment, the band switch for operating each non-locking radio band provided on each surface of the radio receiver corresponding to each radio band is operated by placing the radio receiver on a horizontal surface. You can change the reception radio band by changing the position and placing it on a horizontal surface.

In addition, in the embodiment, FM/MW, SW radio receivers are used as radio receivers.
Taking a 3-band radio receiver as an example, if it is a 2-band radio receiver, one side of the embodiment may not be used, and if it is a 4-band radio receiver, the shape of the radio receiver can be changed to a rectangular shape. Or, you can change the shape of the radio receiver to a polyhedron according to the 1/2 band.

Further, a volume volume volume is also provided for each band, but only one volume volume may be used in common.

Furthermore, the positions and order in which the band switches are installed can be different from those in this embodiment.

Effects of the Invention As described in 1-1- above, in the radio receiver of the present invention, the band switch that turns on and off the power of each radio band operates in the j: -) mode when the receiver is placed on a horizontal surface. Since the radio bands that operate are different, there is no need to change the band selection switch each time the radio band is changed, and the design is extremely advantageous in terms of practical use as it can be made into a polyhedron and can be diversified. 3
