Thus a TV picture receiving circuit is connected to a power supply circuit. The pressure element 23 is detached from the bar 17 when a device main body 1 is turned so that the bar 17 releases the pressure of the bar 16. Then the switch 13 connects a radio receiver circuit to the power supply circuit.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite electronic device that incorporates at least two different electronic devices, such as a television receiver and a radio receiver, into the same housing. The operation of the radio receiver, the operating field of the radio receiver, and the operating state can be easily determined.

At least a television receiver circuit and a radio receiver circuit are incorporated into one housing, and a cathode ray tube of the television receiver and an indicator and operation unit for the television receiver are installed on one side of the housing, A speaker and a radio receiver indicator that are shared by the television receiver and radio receiver are installed on a second surface perpendicular to this − surface, and the housing can be rotated relative to the base. When viewing a television receiver, the first side on which the cathode ray tube etc. are installed faces the front, and when operating the radio receiver, the second side on which the speakers etc. are installed faces the front. The housing is rotated to face the camera, and in conjunction with the rotation of these two bodies, the power supply voltage is switched to the television receiver, radio receiver, and the operation of each electronic device is switched. Composite electronic devices have been proposed.

Figures 1 to 3 show the basic configuration of the above-mentioned composite electronic device. In Figure 5, 1 is a housing (hereinafter referred to as the device main body) in which a television receiving 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 tuning knob 4 for the television receiver, and VHF, UHF are displayed on the first surface.
A band switching unit 6 is installed. The device body 1 also has a television receiver on a second surface perpendicular to this first surface.

A speaker 6° shared by the radio receiver and an indicator 7 for the radio receiver are installed.

The device main body 1 has a power switch and volume adjustment resistor knob 8 on a third surface perpendicular to the first and second surfaces. A tuning knob 9 for the radio receiver is installed. Reference numeral 10 denotes a base, which houses a power supply circuit consisting of an electric transformer, a rectifying and smoothing circuit, a voltage stabilizing circuit, etc. The main body of the device is rotatably connected by 1° to this base 10 using two plate-like swing arms 11 and 12.

These two swing arms 11 and 12 have both ends rotatably connected to the device main body 1 and the base 1o, respectively.
As a result, as shown in Figure 1, the second
The device main body 1 is rotatably provided with respect to the base 1o so that the surface faces the front, and as shown in FIG. 2, 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, set the device main body 1 on the base 1o so that the second surface on which the speaker 6 and indicator 7 for the radio receiver are installed faces the front, as shown in FIG. do.

Here, by operating the switch 89 of the power switch/volume-adjusting resistor switch 9, the radio broadcast of the desired broadcasting station can be listened to. 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 listening to a television receiver, use the swing arms 11 and 12 to rotate the device body 1 so that the first recess in which the cathode ray operator 2, etc. is installed faces the front. do. At this time, the second speaker installed with speaker 6 etc.
The side faces upward.

In the third example, the state of the device body 1 and the swing arm 11, 12 at this time is shown by a chain line.

In the state shown in FIG. 1, the blade 2 faces the base 10 with its lower blade facing, so that it can be protected. Further, in each of the first and second states, the indicators 3 and 7 face the front, and in the case of a television receiver, the operating section is also located at the front, which improves operability. In addition, the switching (rotation) operation for each of the television television, radio receiver, and radio receiver can be easily performed, and at this time, the device body is positioned at the rotation axis of the swing arms 11 and 12. By installing an elastic body that exerts a biasing force in the direction of rotation of device 1, the device body 1 can be rotated smoothly.

In addition, when the main body of the device rotates, this composite electronic device automatically switches the supply of power supply voltage to the television receiver circuit and the radio receiver circuit. Therefore, when the radio receiver is operating as in the first example, if you rotate the device body 1 and set it as shown in Figure 2, the power supply voltage will be applied to the television receiver circuit instead of the radio receiver circuit. After being supplied and rotated, 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 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.
When the contact piece 17 presses the protruding piece 16, the radio receiver circuit 18 is connected to the power supply circuit 19 as shown in FIG. The machine circuit 2o is connected to the power supply circuit 19.

Opposing the contact piece 17 of the changeover switch 13, an opening 21 is provided in the cabinet of the stoneware body 1, and the contact piece 17 can be controlled from the outside through this opening 21. 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.

The fourth problem is when the device main body 1 is set so that the radio receiver can operate as shown in the first problem, and in this case, the presser 22 of the swing arm 11 is pushed through the opening 21 into the device main body 1. 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. Next, from this state, when we want to watch the television receiver, as shown in the fifth example, when the main body 1 is rotated, the presser 22 is separated from the contact piece 17, so the changeover switch 13 is switched, and the radio reception is started. A voltage of 10 B from the power supply circuit 19 is supplied to the television reception circuit 20 in place of the machine circuit 18. The fifth position shows a state in the middle of the rotation, but the state does not change even if the device main body 1 is completely rotated as shown in the second position.

Therefore, assuming that the tuning knob 4 has been tuned in advance, it is possible to receive television broadcasting and display images on the diversion tube 2 at the same time as the tuning knob 4 is turned five times. The same is true when switching to a radio receiver while watching a television receiver.

However, as shown in FIGS. 4 to 6, the operating range of the selector switch 13 as the radio receiver circuit 18 is limited to a miserable and narrow range, and the base 1o There is a drawback that it cannot be used if it is installed in a place where the front side is sloped even slightly low, and for this reason, although not shown in the drawing, a biasing force acts between the swing arms 11 and 12 in the rotational direction of the device body 1. At the same time, it was necessary to set the elastic force of the elastic body to be large in order to stably maintain each usage state. This method not only results in an increase in costs, such as the use of expensive materials, but also causes a decrease in operability.

Also, when watching a television receiver and switching to a radio receiver, the cathode ray tube 20 operates as a television receiver circuit 2o until the image projection direction is almost downward and faces the base 1o. For this reason, there is also the disadvantage that under normal operating conditions, changes in the image projection surface of the cathode ray tube 2 cannot be determined, and the operation of the television and radio selector switch 13 cannot be easily and clearly confirmed. For this reason, the second
It is necessary to arrange a dedicated pilot lamp and install a light indicator, etc. to display the operating status of the radio receiver circuit 18 on the surface of the radio receiver circuit 18, which causes problems such as a complicated assembly structure and an increase in cost.

The present invention eliminates the above-mentioned drawbacks, and the electronic device in which the main functional part is arranged on the first surface operates only when the first surface of the device main body is installed in a normal use state, and the electronic device The electronic equipment, whose main functional parts are located on the second side, operates in conjunction with the rotation of the main body, and switching between the operation of the television receiver and the operation of the radio receiver has excellent operability. It is designed so that it can be easily performed in the current state.

An embodiment of the present invention will be described below with reference to FIGS. 7 to 10. Components that are the same as those in FIGS. 1 to 8 are designated by the same numbers and their descriptions will be omitted.

The major difference from FIGS. 4 and 6 is that a suppressor 23 is integrally provided on the swing arm 12', and the contact piece 17 is controlled by the swing arm 12' and the suppressor 23. The second point is that when the pusher 23 is separated from the contact piece 17, the operation of the changeover switch 13 is switched to the radio receiver circuit 18.

FIG. 7 shows the state in which the composite electronic device according to an embodiment of the present invention is used as a television receiver. Presser 2 that protrudes integrally
3, the television receiver circuit 20 is connected to the power supply circuit 19 as shown in FIG. 8, and the television is ready for use.

- 10,000, by rotating the main body 1 of the device so that the contact piece 17 releases the pressure of the protruding piece 16, the swing arm 12'
The suppressor 23, which is integrally provided on the radio, is separated from the contact piece 17, and the changeover switch 13 connects the radio receiver circuit 18 to the power supply circuit 19, so that the radio is ready for use.

FIG. 9 shows a case where the main body 1 of the device is set so that the radio receiver can operate normally as shown in FIG. 1, and the contact piece 17 of the changeover switch 13 and the other swing arm 1
1' is in a free state.

Therefore, even if the base 10 is arranged at an incline, there will be no malfunction of the radio.

FIG. 10 shows the configuration of the main parts in a state in which the device body 1 is rotated. Even in this state, a suppressor 23 integrally protrudes from the contact piece 17 of the changeover switch 13 on the swing arm 12'. Since the voltage is separated, the radio receiver circuit 18 is supplied with a voltage of 10 B from the power supply circuit 1e, and the radio can be used in a stable state.

As explained above, the present invention is an invention in which the arrangement of the presser which is integrally provided on the swing arm is moved from the structure shown in FIGS. 4 and 5, and the following effects can be obtained.

j) The elastic force acting on the pusher of the swing arm that presses the protruding piece of the changeover switch and the contact piece is structured to maximize the use of the weight of the device itself, so the operating conditions are independent of the installation location. This will stabilize the situation.

2) When switching from a television receiver to a radio receiver, I was in awe! Since the change in the projection circle of the tube serves as an indicator for switching the operation of the television and radio, there is no need for a dedicated operation switching display section in the second enclosure containing the speaker fc.

3) In the conventional example, it is absolutely necessary to use an elastic body that repulses each other between both swing arms, and as a result, when the main body of the device rotates, an unreasonable reaction is caused to the base and the blade edge. However, in the present invention, by rationally setting the fulcrums of both swing arms, even if the elastic body is removed, stable cutting operation and stable use can be achieved using only the weight of the device itself. The state is obtained.

4) Since the mutual dimensional tolerance between the changeover switch, the aperture, and the suppressor of the swing arm can be set to be large, it is possible to promote grand prize production using inexpensive means and contribute to cost reduction.

6) In electronic equipment that has a television receiver on the first side and a radio receiver and speakers on the second side, operability has improved dramatically and the operation switching has improved. can be done naturally. Although the above embodiments have been described in terms of a combination of a television receiver and a radio receiver, 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 casing is rotatably installed so that the surface on which the functional parts are arranged faces the front, and a changeover switch is provided to select each functional part arranged on two sides of the casing. By configuring the structure so that it operates in conjunction with the rotation of the body and immediately responds to the first surface, each function is automatically switched when the housing is rotated, and it is necessary to operate the switch again. There is no need to do this, making it extremely convenient in practice.

Furthermore, the operating states of both functions can be determined extremely easily.

In particular, the effect can be further enhanced by application to an electronic device having a cathode ray tube, a pilot lamp, a light indicator, etc. whose first surface changes in luminescence pattern depending on the operating state.
