JPH07110303B2 - Joystick device with image display - Google Patents

Description

The present invention relates to a joystick device for a home video game machine.

(Prior Art) In a conventional home video game machine, a game cartridge containing a game program is set in the main body of the video game machine, an image is displayed on a home TV, and a joystick for operation is mounted on the video game machine. You can enjoy the game by connecting and operating the characters in the game screen.

(Problems to be Solved) These home video game consoles cannot be used in a place without a TV because they use a TV set in a home for projecting images, and cannot be played outdoors.

Recently, a handheld video game console was developed,
A liquid crystal monitor is provided in the main body of the video game, and a product in the form of enjoying the game by setting the game cartridge in the main body and operating the operation unit provided on the main body surface is becoming mainstream, but in terms of operability The home video game console has a separate joystick, which makes it extremely light and easy to operate, and the home video game console is by far superior in terms of the type and performance of the game cartridge of the video game itself.

Therefore, the present invention provides a joystick device that enables the home video game console itself to be used outdoors, such as in an automobile without a television.

(Means for Solving the Problems) Therefore, in the present invention, a game cartridge containing a game program is set in the main body of the video game machine, an image is displayed on a home-use television, and a joystick for operation is displayed on the television game machine. In a joystick used in a home-use television game machine of a type in which a player is connected to enjoy a game, a direction operation switch and a push button switch are arranged on the surface of the joystick and a liquid crystal display element is provided.

A signal line for sending a signal from at least the operation switch to the joystick terminal of the home video game machine is provided inside the joystick.

Further, in the joystick, a converter circuit for converting a television signal from a home video game machine and a conversion signal from the converter circuit are sent to a driver circuit, and the driver circuit converts the signal into an image projected on the liquid crystal display element. An image signal is sent to the liquid crystal display element to display an image.

Furthermore, the joystick with an image display is provided with a sound amplification circuit for amplifying a sound signal from a television signal, and the sound amplification signal from the sound amplification circuit is sent to a sounding means including a speaker or an earphone jack.

(Embodiment) An embodiment of the present invention will be described in detail. FIG. 1 shows a joystick with a liquid crystal display connected to a home video game machine.

A liquid crystal screen 2 is provided on the surface of a joystick 1 with a liquid crystal display, and a cross direction operation plate 3 is provided around the liquid crystal screen 2.
Also, a plurality of push buttons 4 are provided and connected to a commercially available home video game machine 6 with a connection cord 5.

In the home video game machine 6, the game cartridge 8 is set in the game cartridge insertion slot 7, and the connection cord 5 of the joystick with liquid crystal display 1 is connected to the joystick insertion slot 9 and the TV signal outlet 10.

FIG. 2 shows a block diagram of the internal circuit of the joystick with liquid crystal 1. From the connection cord 5, the signal lines for the joystick cross direction operation switch 3 and various push buttons 4 are directly or via the control circuit 20. It is connected.

Next, the video signal, the composite signal or the RGB signal coming from the television signal outlet 10 of the home video game machine through the connection cord 5 enters the converter conversion circuit 21 and is sent from the home video game machine 6. The signal is converted into a signal for the liquid crystal screen 2 and displayed as an image on the liquid crystal screen 2 via the driver circuit 22.

Furthermore, the sound signal in the TV signal is a sound amplification circuit.
It is amplified at 23 and connected to the speaker 24 or the earphone jack 25, and the volume 26 is connected to the sound amplification circuit to adjust the volume of sound.

Furthermore, in order to make the display on the liquid crystal screen easier to see, it is possible for the fluorescent backlight 28 to illuminate the liquid crystal screen 2 from the rear via the inverter circuit 27.

Power supply line for operating the circuit and liquid crystal screen 2
Vcc is powered by a dedicated power adapter (not shown).

The description of the present invention has been made by taking the home video game console as an example, but the application software that can be operated by using the joystick can be used not only in the home video game console but also in a personal computer which needs a separate video display monitor. Of course.

(Operation and Effect) The operation and effect will be described based on the present invention described above. By inserting a liquid crystal display in the joystick, the home video game machine can be separated from the home TV, and the video game machine body can be separated. Since it can be done separately, the weight can be reduced, the hands do not get tired even for long hours of play, the LCD can be operated easily, and you can play in a place without a TV such as in a car, Furthermore, by separating it from the main body of the video game console, it can be made very light, and the performance of the home video game console can be used as it is, and it is possible to play freely from a wide variety of game cartridges.
