Description

The present invention relates to a home - use crane game machine.
Recently, as one of game machines which is often found in the entrance of an amusement arcade, a bookstore, a CD shop or the like, there is a crane game apparatus which a prize on the inside is caught by controlling a crane. Many prizes are housed inside of the crane game apparatus, when a player stops the crane at the arbitrary position by controlling the movement in the lateral and longitudinal direction thereof with buttons after inserting a coin, the crane moves down to the bottom at this position with a catcher being opened and then moves up with the catcher being closed, then, the player can get a prize if the catcher catches it successfully. One example of such a game machine is disclosed in WO 2005/025704 .
However, this crane game apparatus could not be played in the home because it is generally very large in size. So, downsized home-use crane game machines to play in the home are provided. For example, a game machine, of which a crane moves in lateral direction after inserting a coin, and where a player stops the lateral movement of the crane and controls the vertical movement of a catcher by operating a lever for getting a prize, is provided in Japanese Patent Application Publication H06-319869 .
In a conventional home-use crane game machine described above, the crane keeps moving for a fixed time after inserting a coin, thus, the player can catch prizes many times with one coin. And, the crane only moves in a lateral direction, thus, the player only controls the vertical movement of the catcher by operating the lever. Although the appearance and game structure of the conventional home-use crane game machine are similar to the crane game apparatus disposed in the amusement arcade or the like, they are two completely different game machine, the player does not have a sensation of strain that the game can not be started over because multiple challenges can be done with one coin.
Additionally, a prize drops on moving the crane or cannot be caught often because the catcher is small and for that reason the prize can not be easily caught, thus, young children can not play easily.
The present invention was made in view of above problem, an object of this is to provide a home-use crane game machine which is similar to a real machine, which the player has a sensation of strain during the play and which young children can play easily.
The present invention provides a home-use crane game machine according to claim 1.
Preferably, the housing part is a cylinder having a square section which four transparent plates are disposed between four support columns, and light emitting diodes (LEDs) are internally fitted in the support columns and one of the four transparent plate is openably and closably fixed.
Moreover, the base part may have an infrared sensor which detects falling of a prize, and the control device reversely rotates the Z axis motor that serves as the power of the catcher, operates a sound output device, and turns on the light emitting diodes internally fitted in the support columns of the housing part when the infrared sensor reacts.
Also, the base part may have a prize receiving tray, and the prize receiving tray is protruded from the base part to the front side.
The catcher may comprise a catcher main body part and upper supporting part mutually interlocked with each other, wherein a first chain is connected to the catcher main body part and a second chain is connected to the upper supporting part, the catcher main body part is opened when the catcher is hung by the second chain and the catcher main body part is closed when the catcher is hung by the first chain.
According to the present invention described above, since the first button becomes unoperatable after the crane main body was moved in X axis direction with the catcher by pressing the first button, the catcher can be moved only once in X axis direction and Y axis direction with one coin, thus, the home-use crane game machine which is similar to real machine and is played with a sensation of strain can be provided.
Also, since the standing wall plates are formed to the catcher, the prize does not drop when the crane main body and catcher move, thus, young children can play easily. And, since the prize receiving tray is protruded to the base part, young children can easily take the prize.
And, since one of the transparent plates of the housing part is fitted being opened and closed, prizes may be easily housed in the housing part. And, since LEDs are output with linking sounds, young children's interest can be aroused.
Additionally, since the prize receiving tray of which the center is lowered is provided on the base part, the small number of residual prizes can be gathered in the center thereof, thus young children can easily move the catcher to the position of prizes. And, since the prize-holding space of the catcher and the size of prize are approximately equal, the prize can be easily held with the catcher.

Then, the action of the crane game machine 1 of the embodiment is described below. When batteries are housed and the main switch 102 is turned ON, as shown in Fig. 6, the control device 101 determines whether the crane main body 54 is in an initial position by using signals from the X axis first switch 112 or Y axis first switch 114 (STEP S1), and moves the crane main body 54 to the initial position if it is not in the initial position (STEP S2). If it is confirmed that the crane main body 54 is in the initial position in the STEP S1, the insertion charging of a coin is operated (STEP S3), and the sound begins to be output and the LED group 108 begins to be emitted if the coin is inserted (STEP S4). In this time, the voice of characters and the like is supplied firstly and then the BGM (Back Ground Music) and the like are supplied. When the output of the voice of characters is completed in this sound output step, the first button 24 can be operatable.
And then, the control device 101 determines whether a button operatable prescribed time passes after inserting the coin (STEP S5), the control device 101 returns to the standby state of before inserting the coin if the prescribed time has passed. If the prescribed time has not passed, the control device 101 determines the X axial motor movable signal generated by pressing the first button 24 (STEP S6), and the crane main body 54 starts to move in the X axis direction if the X axial motor movable signal is output (STEP S7)
Continuously, the control device 101 determines whether the X axial motor movable signal is continuously output (STEP S8), the movement of the crane main body 54 in X axis direction is stopped if the X axial motor movable signal is not output (STEP S10). If the X axial motor movable signal is continued, the control device 101 determines the X axial motor stop signal which is output in case that the crane main body 54 moves to the limit position so as to press the X axis second switch 113 (STEP S9), the movement in X axis direction is stopped if the X axial motor stop signal is output (STEP S10). The control device 101 continues to move the crane main body 54 in X axis direction if the X axial motor stop signal does not output in the STEP S9 detecting the X axial motor stop signal. And, when the axial motor movable signal does not continue or the movement in X axis direction is stopped by inputting the X axial motor stop signal, the first button 24 can not be operated (STEP S11).
The control device 101 confirms again whether the prescribed time has passed after inserting the coin after the first button 24 was operated (STEP S12), the crane main body 54 is returned to the initial position so as to be finished if the prescribed time has passed (STEP S2). And, when the prescribed time has not passed, as shown in Fig. 7, the control device 101 determines the Y axial motor movable signal generated by pressing the second button 25 within a prescribed time frame (STEP S13). And then, the crane main body 54 starts to move in Y axis direction if the Y axial motor movable signal is output (STEP S14).
And, the control device 101 determines whether Y axial motor movable signal is continuously output (STEP S15), the movement of the crane main body 54 in Y axis direction is stopped if the Y axial motor movable signal is not output (STEP S17). If the Y axial motor movable signal is output, the control device 101 determines the Y axial motor stop signal which is output in case that the crane main body 54 moves to the limit position so as to press the Y axis second switch 115 (STEP S16), the movement in Y axis direction is stopped if the Y axial motor stop signal is output (STEP S17). Where, the crane main body 54 continues to move in Y axis direction if the Y axial motor stop signal is not output in STEP S16.
When the movement of the crane main body 54 in Y axis direction is stopped, the Z axis motor 111 for moving the catcher 65 starts to rotate forwardly and the catcher 65 is moved down with opening (STEP S18) . And, after the catcher 65 is moved down to the bottom end with the passage of prescribed time, the Z axis motor 111 starts to rotate reversely and the catcher 65 is moved up with closing (STEP S19). And, when the catcher 65 is moved up to the upper end by the time same as falling time, the crane main body 54 is returned to the initial position (STEP S20),
The catcher 65 starts to move downwardly by forwardly rotating the Z axis motor 111 of the crane main body 54 returned to the initial position by the control device 101 (STEP S21), and the success and failure of the acquisition of prize 6 is detected by the infrared sensor 106 (STEP S22). At this point, when the control device 101 receives the acquisition success signal from the infrared sensor 106 in case that the prize 6 was successfully caught, the sound which praise the success of acquisition is output and the LED group 108 are emitted (STEP S23), and then the catcher 65 is returned to the initial position with reversely rotating the Z axis motor 111 (STEP S24) and all operations are finished. On the other, since the infrared sensor 106 does not react if the prize 6 was not caught, the control device 101 moves the catcher 65 downward with continuing the forwardly rotating of the axis motor 111 (STEP S25), and then moves the catcher 65 upwardly with reversely rotaring the Z axis motor 111 (STEP S26) and all operations are finished.
In accordance with the crane game machine 1 of the present embodiment, the crane main body 54 is controlled by the first button 24 for controlling the movement in X axis direction and the second button 25 for contrelling the movement in Y axis direction, and the first button 24 does not react even it is pressed again after releasing, thus, one play can be by one coin. Therefore, the crane game machine 1 close to a real machine can be provided, and a player can be enjoyed with a sensation of strain during the play by paying attention the timing of releasing the first button 24 or second button 25.
Also, the front edge of the catcher 65 is formed like a hook so as to be horizontal state in case of closing, and wall surfaces are formed using the part of the holding member 73 in the side surfaces facing each other and standing wall plates 76 are mounted at the opening sides, thus, the crane game machine 1 which young children can catch the prize 6 with a high success rate can be provided. Moreover, the more popular crane game machine 1 among young children can be provided by adjusting the picture of characters or sounds to the machine. And, since the prize receiving tray 35 is protruded from the base part 2, young children can easily take out the prize 6 which is successfully caught.
