Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite electronic device in which at least two different electronic devices, such as a television receiver and a radio receiver, are incorporated into the same housing. This makes it easy to switch the operation of the radio receiver.

In one example of the present invention, at least a television receiver circuit and a radio receiver circuit are incorporated into one housing, and an indicator for a cathode ray tube of the television receiver and an indicator for the television receiver is provided on one side of the housing. A speaker and an indicator for the radio receiver, which are shared by the television receiver and the radio receiver, are installed on the second surface perpendicular to this one surface. When viewing a television receiver, the first side on which the cathode ray tube etc. are installed faces the front, and when operating a radio receiver, the first side on which the speakers etc. are installed faces. Rotate the housing so that the side 2 faces the front, and in conjunction with the rotation of the housing, switch the supply of power supply voltage to the television receiver and radio receiver, and switch the operation of each electronic device. This is what I decided to do.

An embodiment of the present invention will be described below with reference to the accompanying drawings. Figures 1 to 3 show the basic configuration of the composite electronic device according to the present invention. In the figure, 1 is a housing (hereinafter referred to as the device main body) in which a television receiver circuit and a radio receiver circuit are incorporated. ), the cathode ray tube 2 of the television receiver, the channel indicator 3 for the television receiver, the channel selection knob 4 for the television receiver, and the VHF/TV receiver are displayed on the first side.
A UHF band switching knob 5 is installed. Further, the device main body 1 has a speaker 6 shared by a television receiver and a radio receiver, and an indicator 7 for the radio receiver installed on a second surface orthogonal to the first surface. The device body 1 has a power switch/volume adjustment variable resistor knob 8 and a radio receiver tuning knob 9 installed on a third surface perpendicular to the first and second surfaces. There is. Reference numeral 10 denotes a base, which contains a power supply circuit including a power transformer, a rectifying and smoothing circuit, a voltage stabilizing circuit, and the like. The device main body 1 is rotatably connected to the base 10 using two plate-like swing arms 11 and 12. These two swing arms 11 and 12 have both ends connected to the device body 1,
The second base 10 is rotatably connected to each of the bases 10, and the second speaker 6 and the like are installed as shown in FIG.
so that the side faces the front, and as shown in Figure 2.
The device main body 1 is rotatably provided with respect to a base 10 so that the first surface on which the cathode ray tube 2 and the like are installed faces the front. At this time, the device main body 1 is stably set in the state shown in FIG. 1 and the state shown in FIG. 2, respectively.

Therefore, when operating the radio receiver, as shown in FIG. Set to .
Here, by operating the power switch/volume adjustment variable resistor knob 8 and the channel selection knob 9, it is possible to listen to the radio broadcast of a desired broadcast station. In FIG. 3, the state of the device main body 1 and swing arms 11, 12 at this time is shown by solid lines.

On the other hand, when viewing a television receiver, the device main body 1 is rotated using the swing arms 11 and 12 so that the first surface on which the cathode ray tube 2 and the like are installed faces the front. At this time, the second surface on which the speaker 6 and the like are installed faces upward.
In FIG. 3, the state of the device main body 1 and the swing arms 11, 12 at this time is shown by dashed lines.

In the state shown in FIG. 1, the cathode ray tube 2 faces downward and faces the base 10, so that it can be protected. Furthermore, in each of the states shown in FIGS. 1 and 2, the indicators 3 and 7 face the front, and in the case of a television receiver, the operating section is also located in the front, which improves operability. In addition, switching (rotating) the television receiver and radio receiver to their respective usage states can be easily performed, and at this time, the device body 1 is rotated so that it is positioned at the rotation axis of the swing arms 11 and 12. If an elastic body is installed that exerts a biasing force on the device body 1,
The rotation operation can be performed more smoothly.

The present invention automatically switches the supply of power supply voltage to the television receiver circuit and the radio receiver circuit when the main body of the device rotates. Therefore, when the radio receiver is operating as shown in Fig. 1, if the device body 1 is rotated and set as shown in Fig. 2, power is supplied to the television receiver circuit instead of the radio receiver circuit. voltage is supplied,
After rotation, the television receiver can be operated without having to operate a switch again.

The configuration of this changeover switch section will be explained using FIGS. 4 to 6. In the figure, 13 is a television-radio changeover switch, which is fixed to a mounting bracket 14. This mounting bracket 14 is fixed to a cabinet constituting the device main body 1 with a plurality of screws 15 to secure the television-radio changeover switch 13 to the device main body 1. The changeover switch 13 includes a projecting piece 16 and an elastic contact piece 17.
When the contact piece 17 presses the protrusion 16, the radio receiver circuit 18 is connected to the power supply circuit 19 as shown in FIG. 20 is connected to the power supply circuit 19.

Opposed to the contact piece 17 of the changeover switch 13, an opening 21 is provided in the cabinet of the device main body 1, and the contact piece 17 can be accessed from the outside through this opening 21.
It is possible to control the In this example, a pusher 22 is integrally provided on one of the swing arms 11 to project, and the contact piece 17 is controlled by the swing arm 11 and the pusher 22.

FIG. 4 shows a case where the device main body 1 is set so that the radio receiver can operate as shown in FIG.
2 enters into the device main body 1 through the opening 21 and presses the contact piece 17, and further presses the protruding piece 16, so that the changeover switch 13 switches the + from the power supply circuit 19.
B voltage is supplied to the radio receiver circuit 18. In order to watch the television receiver next time from this state, when the device body 1 is rotated as shown in FIG. 5, the pusher 22 separates from the contact piece 17, so the changeover switch 13 is switched and the radio receiver circuit is turned. 18
Instead, the +B voltage from the power supply circuit 19 is supplied to the television receiver circuit 20. Although FIG. 5 shows the state in the middle, this state does not change even after the device main body 1 has been completely rotated as shown in FIG. Therefore, assuming that the tuning knob 4 has been tuned in advance, it is possible to receive television broadcasts and display images on the cathode ray tube 2 at the same time as the rotation. This also applies when viewing a television receiver and switching to a radio receiver.

In the above embodiments, a combination of a television receiver and a radio receiver has been described, but the present invention is not limited to this and can be applied to combinations of other electronic devices.

As described above, according to the present invention, at least two different types of electronic devices are built into one housing, at least the main functional parts of each are arranged on two sides of the housing, and the housing is put into use. The housing is rotatably installed so that the surface on which the functional parts are arranged faces the front, and a switch is provided to select each functional part arranged on two sides of the housing. By configuring it to operate in conjunction with the rotation of the body, each functional section is automatically switched when the housing is rotated, eliminating the need for additional switch operations, making it extremely convenient in practice. Become something.
