Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a television game device in which a game function is integrally added to a television receiver.

<Prior Art> Conventional general television game devices include those that integrally have a game-specific CRT (cathode ray tube) as a display device, and those that utilize the CRT screen of an existing television receiver. Particularly in the latter case, the game output is usually RF converted into an empty channel carrier wave within the television game device and then supplied to the antenna terminal of the television receiver.

Problems> Therefore, in this case, not only is it necessary to have an RF converter built into the video game device, but also the receiving sensitivity of the television receiver during gaming is poor, which makes the screen easily distorted and reduces the interest in the game. .

Furthermore, in conventional devices, the program contents of several types of games are usually stored in the device from the beginning, so it is impossible to change the program contents later, and it is impossible to change the program contents afterward. It was a matter of switching.

Solution to Problems> The present invention has been made in view of the above points.A cassette storage is provided in a part of a television receiver incorporating a game CPU and various interfaces, and a cassette storage is provided in the storage in advance. To provide a television game device in which a tape cassette or a read-only memory (RC)M (read only memory) cassette containing game program contents can be selectively loaded.

<Examples> The present invention will be described below according to examples shown in the drawings. 1st
The figure shows an external view of one embodiment of the television game device of the present invention, and FIG. 2 shows a block diagram of the same embodiment.

First, in FIG. 1, l indicates the main body of the television receiver, and inside the receiver main body 1 there are built-in a general television receiver circuit including CBr4, a game CPU, various interfaces, etc. A cassette storage 3 is provided at the lower front, and a control signal input terminal 4 is also provided, and a game control unit 6 is connected to the input terminal 4 via a cable 5. A ROM cassette 7 containing game program contents is detachably attached.

Next, in Figure 2, 8 is an antenna, 9 is a tuner, l
O/''i video intermediate frequency amplification/detection circuit, 11 is an audio circuit, 12 is a speaker, 13 is a video amplification circuit, 14 is a chroma circuit, 15 is a video output circuit, and 16 is a synchronization/deflection circuit. A television receiver circuit similar to that of the color television receiver is configured.Furthermore, in this case, a signal switching circuit 17 and a game signal generation interface 18 are added to such a normal television receiver circuit.
, RAMI 9 for video, CPU for game control
20 and an external input interface 7/8 21 are additionally built-in, and a game function is provided as well as a television reception function.

The television reception operation of the apparatus constructed from the above is well known, and its explanation will be omitted here, and the operation of the television game will be particularly explained below.

First, when the power is turned on and the television receiver circuit is operating, insert the ROM cassette 7 of the desired game into the cassette storage 3 on the front of the receiver body 1. is input to the game control cPU 20, and at this time the CPU 20
The television reception mode is switched to the television game mode based on a command from the television reception mode. That is, at this time, due to the switching operation of the signal switching circuit 17, the game signal obtained from the composite signal generation interface 18 is transferred to the audio circuit 11 and the video amplification instead of the television video signal obtained from the video intermediate frequency amplification/detection circuit 10. The signal is supplied to the circuit 13 and the chroma circuit 14.

In this case, when the ROM cassette 7 is installed in the cassette storage 3, the program contents previously stored in the ROM in the cassette are read out via the external input interface 7 Ace 21 and temporarily stored in the video RAM 19 based on the instructions of the CPU 20. After being written, it is read out again and supplied as a game signal to each of the circuits 11, 13, and 14 via the interface 18 and signal switching circuit 17. As a result, an image corresponding to the game content is displayed on the screen of the CBr 4, similar to a normal video game device, sound effects are emitted from the subica 12, and the player operates the game control unit 6 while looking at the screen. You can enjoy the game.

And if the player wants to exchange game contents, RO
By simply replacing the M cassette 7, it is possible to enjoy a game with a different program content as desired.

Although the ldROM cassette 7 is used in the above embodiment, a tape cassette may be used instead.

Effects> According to the television game device of the present invention, since the game CPU and various interfaces are built into the television receiver body as described above, the game signal output is particularly
Since the signal can be supplied to the television receiver circuit in place of the television video signal without RF modulation by the F converter, there is no risk of image disturbance during the game, and the game becomes more interesting.

Further, according to the television game device of the present invention, since the device is tilted vertically, it is possible to easily enjoy various games by simply replacing the cassette.
