To watch the TV receiver, the main body 1 is set on the base 10 by being turned that the 1st surface faces the front, the switch is changed over similarly through the swing arms 11 and 12.

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,
In addition, the cathode ray tube of the television receiver and the indicator and operation unit for the television receiver are installed on one side of this housing, and the second side perpendicular to this side is installed for the television receiver and the radio receiver. When listening to shared spill power and radio images, the first side on which the cathode ray tube etc. are installed faces the front, and when operating the radio receiver, the first side on which the speakers etc. are installed faces. Fully rotate the casing so that the side 2 faces the front, and in conjunction with the rotation of the casing, cut off the supply of power supply voltage to the television receiver and radio receiver, It is designed to switch the operation.

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 vaned case (hereinafter referred to as the main body of the device) in which a television receiver circuit and a radio receiver circuit are assembled. ), and a cathode ray tube 2 for the television receiver, a channel indicator 3 for the television receiver on the first side. A channel selection knob 4 for a television receiver and a VHF/UHF band switching knob 5 are 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 main body 1 has a power switch and volume adjustment variable resistor knob 8 on a third surface perpendicular to the first and second surfaces. A tuning knob 9 for the radio receiver is installed. Also, 1° is the base, which has a power transformer and rectifier and smoothing circuit inside.

It has a built-in power supply circuit consisting of a voltage stabilization circuit, etc. The device main body 1 is rotatably connected to the base 1o using two plate-like swing arms 11 and 12'i. These two swing arms 11 and 12 each have both ends attached to the device body 1. It is rotatably connected to each side of the base 1C, so that the second surface on which the speaker 6, etc. are installed faces the front, as shown in FIG. A device main body 1 is provided rotatably with respect to a base 1o.

At this point, 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 a radio receiver, spill force 6. The device body is set on the 1,000 base 1o so that the second surface on which the indicator 7 for the radio receiver is installed faces the front.

Here, by operating the knob 89 of the power switch/variable resistor for volume adjustment and the channel selection knob 9, it is possible to listen to the radio broadcast of the 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 watching a television receiver, the swing arm 11. , 12 to rotate the main body 1 of the device so that the first surface on which the negative REI 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.

Figure 3 shows the equipment body 1 and the swing at this time.
7 The state of arms 11 and 12 is shown by a dashed line.

In the state shown in FIG. 1, the cathode ray tube 2 faces downward and faces the base 1o, so that it can be protected. Further, in each of the states shown in FIGS. 1 and 2, the indicators 3.7 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, the switching (rotation) operation of the television receiver and radio receiver to their respective operating states can be easily performed. By installing an elastic body that exerts a biasing force in the direction of rotation, the device body 1 can be rotated 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, as shown in Figure 1, when one radio receiver is operating, one
If you turn the switch and set it as shown in Figure 2, the power supply voltage will be supplied to the television receiver circuit instead of the radio receiver circuit. It can be made to work.

The configuration of this changeover switch section will be explained using FIGS. 4 to 6. In the figure, 13 is a TV-radio selector switch,
It is fixed to the mounting bracket 14. This mounting bracket 14 is fixed to the cabinet constituting the device main body 1 with a plurality of screws 16 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.
7. With the protrusion 16 pressed, the radio receiver circuit 18 is connected to the power supply circuit 19 as shown in FIG.
When the contact piece 17 releases the pressure on the protruding piece 16, it switches to connect the television receiver and sleep circuit 20 to the power supply circuit 19.

An opening 21 is provided in the cabinet of the main body 1 of the device opposite to the contact piece 17 of the changeover switch 13, and the contact piece 17 can be controlled from the outside by passing through the opening 21 entirely. In this example, one swing arm 1
A pusher 22 is integrally protruded from the swing arm 1.
1 and a pusher 22 to control the contact piece 17.

FIG. 4 shows a case where the device main body 1 is set so that the radio receiver can operate as shown in FIG. By entering the inside and pressing the contact piece 17 and further pressing the protruding piece 16, the changeover switch 13 supplies the 10B voltage from the power supply circuit 19 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 is separated from the contact piece 17, so the changeover switch 13 is switched, and the radio receiver circuit is turned. A voltage of 10 B is supplied from the power supply circuit 19 to the television receiver circuit 2o instead of the voltage 18. Figure 6 shows the state in the middle, but the second
Even if the main body 1 of the device is completely rotated as shown in the figure, the state remains unchanged.

Therefore, assuming that the tuning knob 4 has been tuned in advance, it is possible to receive television broadcasting and display images on the cathode ray tube 2 at the same time as the rotation. The same thing happens when you are watching a television set and then switch to a radio receiver.

In addition, although the case of the combination of a television receiver and a radio receiver was demonstrated in the said Example, this invention is applicable not only to this but also to the combination 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 all of the main functional parts of each are arranged on two sides of the housing, and the housing is put into use. The functional parts are arranged accordingly and are rotatably installed so that the facing side faces the front, while a changeover switch is provided to select each functional part arranged on two sides of the case, and this changeover switch is By configuring it to operate in conjunction with the rotation of the casing, when the casing is rotated, each functional section is automatically switched.There is no need to perform switch operations again, making it practical. This makes it extremely convenient.
