Description

[Detailed Description of the Invention] The present invention relates to a device that incorporates a color television receiver and a magnetic recording/reproducing device into the same housing, and records data on a recording medium using magnetic field lines from a degaussing coil of a color cathode ray tube. The aim is to provide a device whose state is not disturbed.

Recently, devices have been developed in which a television receiver and a magnetic recording/reproducing device such as a tape recorder are incorporated into the same housing. First, the general structure will be explained with reference to FIGS. 1 and 2. Reference numeral 1 is a housing, 2 is a cathode ray tube of a television receiver, 3 is a channel knob thereof, and 4 is its various adjustment knobs. The image receiving circuit portion is omitted from illustration. Further, 5 is a cassette tape type tape recorder section housed in the same housing 1, 6 is its cassette tape storage section, and 7 is its operation button.

However, when such a device is used as a color television receiver, a disadvantage arises in that the recording condition of the cassette tape is adversely affected. This is because when the degaussing coil 9 installed in the shield case 8 of the cathode ray tube 2 operates, considerably strong lines of magnetic force are generated from the degaussing coil 9, and the lines of magnetic force reach the cassette tape and destroy the recorded contents. This is because the data may be erased or disturbed.

Therefore, the present invention aims to eliminate such drawbacks, and one embodiment thereof will be described in detail below with reference to FIGS. 3 to 5. Here, first, a switch 10 is provided in the cassette tape storage section 6 of the tape recorder section 5, and by protruding its operation pin into the cassette tape storage section 6, the cassette tape can be loaded into the cassette tape storage section 6 as shown in FIG. 12
When the switch is attached, the operating pin 11 is pushed and the switch 10 is opened. 13 is a lid that can be opened and closed. and,
This switch 10 is connected to the degaussing coil 9 as shown in FIG.
When the cassette tape 12 is loaded and the switch 10 is open, no current flows through the degaussing coil 9 and the degaussing operation is stopped. In FIG. 5, 14 is an AC power plug, 15 is a power switch, 16 is a positive characteristic thermistor, and 17 is an image receiving circuit.

In this way, in this device, when the cassette tape 12 is loaded in the cassette tape storage section 6, the switch 10 is opened and the degaussing coil 9 is no longer demagnetized, so that the degaussing coil 9 is prevented from being degaussed by the lines of magnetic force during degaussing. It has become possible to completely eliminate the possibility of any adverse effect on the cassette tape 12. It should be noted that when the cassette tape 12 is not attached, the switch 10 is closed and the demagnetization effect is performed, so that the adverse effect on the color cathode ray tube can be almost eliminated.

It goes without saying that the present invention can be applied to devices other than tape recorders that use various recording and reproducing devices as long as they use magnetic recording media.

As detailed above, in the present invention, a switch is provided that stops the operation of the degaussing coil when a recording medium is loaded into the recording medium storage section.
Even in a device in which a color television receiver and a magnetic recording/reproducing device are housed in the same housing, a practical device that does not adversely affect the recording state of the recording medium can be obtained.

Further, since the switch is switched when a recording medium is stored in the recording medium storage section, there is no need to perform a switching operation again, and the operability is extremely good.
