FISHING GAME DEVICE
This invention relates to a fishing game apparatus and, 5 more particularly, to a novel game apparatus having a casting rod to be electrically connected to a television monitor to allow casting with the casting rod, thereby playing a fish game on the game screen.
Conventionally, fishing games has been popular in video game. Playing a fishing game on a television is costly because of a need to prepare a video game console and :5 fishing game software. With a controller attached to the video game console, there is short of a sense of reality. Hence, nowadays the controllers dedicated for fishing games have bee available in the market. The use of such an exclusive controller pushes the costs up. 20
On the other hand, fishing game apparatus of a casting rod shape is also available. This fishing game apparatus has, in a casting rod, an acceleration switch built-in, the game processor and a liquid crystal display. A casting action in an actual manner gives an acceleration to the rod. If the 25 magnitude of the acceleration is greater than a certain value, the acceleration switch turns on. The game processor detects the timing when the acceleration switch turns on. On the basis of the timing, the game processor determines kind and size of available fishes by making reference to a data table, 30 thereby determining whether a fish is to be hooked up or not. The game player is allowed to watch a series of processes with displaying a fishing field or water place on the liquid crystal display.
In the latter conventional art, not a TV game, a game player needs not to prepare a costly video game apparatus, therefore the player can enjoy a fishing game readily. However, the LCD screen is too small to watch the game image, the fishing game still lacks reality.
Therefore, it is a primary object of the present invention to provide a fishing game apparatus which displays a game ^ scene on a television monitor to allow a fishing game to be played with such a realistic sensation as not to be offered by the conventional TV video game.
The present invention is a fishing game apparatus for displaying a game scene of a fishing game on a television 50 display, the fishing game apparatus comprising: a casting rod; an acceleration sensor provided in the casting rod to output an acceleration signal during casting; and a game processor provided in the casting rod to determine a casting distance on the game screen by processing an acceleration 55 signal.
The casting rod incorporating the acceleration sensor and game processor is connected to the television monitor through an AV cable, etc. When a game player does casting action using the casting rod (casting) toward the monitor go screen, the game processor calculates a casting distance in accordance with an acceleration signal from the acceleration sensor, and displays on the screen a splashdown point in a position according to the distance.
Incidentally, in the case the casting rod has a function of 65 a light gun, the game processor calculates a position of a light spot on the television monitor according to an output
from light spot detecting means and displays a rod on the game screen as if a line is casted in the direction of the light spot.
According to the invention, a fishing game can be readily enjoyed because of unnecessity of preparing a video game console or game software. Displaying a game image on a television monitor allows a game player to have more realistic sensation than that of the conventional liquid crystal display.
Further, it is possible to detect a casting intensity, or casting distance, according to an acceleration signal sent from an acceleration sensor. Thus, reality is further enhanced.
The above described objects and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawing.

BEST MODE FOR CARRYING OUT THE
A fishing game apparatus 10 of an embodiment of the present invention as illustrated in FIG. 1 includes a casting rod 12. The rod 12 is connected to an AV terminal 14 of a television monitor 16 through an AV cable 18. When a game player does casting action using the casting rod 12 toward a screen of the television monitor 16, a rod all (FIG. 2) casts a line on the game screen of the monitor 16. The television monitor 16 can use a display capable of displaying an image by a video signal for television monitor such as, raster scanning display and a dot matrix display. However, in the case a direction identifying function cooperative with the television monitor 16 is added, as hereinafter described, a raster scanning display must be used as the television monitor 16.
The casting rod 12 has a housing 30 (FIG. 3) formed of plastic, or the like. The housing has, on the top surface, a power supply switch 20, a select key 22 and a tension key 24. The select key 22 on a menu screen is operated to select a lure kind and a fishing field (water place). The tension key 24 is used to adjust a tension of a fish line displayed on the game screen, and includes upward and downward keys for increasing and decreasing the tension.
A reel handle 26 is provided in a lower part of the housing of the casting rod 12 which the game player is allowed to reel in order to hook a fish during fighting, or the like. The casting rod 12 has a relatively tough fish line 28 formed of plastic, or the like. The fish line 28 has one end fixedly held at tip of the casting rod 12, and the other end is elastically held at the lower part of the housing the reel handle is provided. When shaking the casting rod 12 for casting, the
