Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing an external configuration of a crane game machine 10 according to the present embodiment. As shown in FIG. 1, the crane game machine 10 includes an upper housing 12 and a lower housing 13. The upper housing 12 is partially covered with a transparent plate 15 such as an acrylic plate on the front and side surfaces, and a prize field 16 inside the housing can be seen through the transparent plate 15. The transparent plate 15 is configured to be openable and closable on the front side, for example, and can be opened when a premium is exchanged or supplemented in the premium field 16 or when a premium is placed on a seesaw plate 19 described later. Further, the transparent plate 15 may be removable.

  In the crane game machine 10 according to the present embodiment, the prize field 16 is divided into two on the left and right by the partition plate 14 so that two players can simultaneously execute the game. A prize can be loaded on each of the two prize fields 16 divided by the partition plate 14. In addition, on the front side (player side) of the crane game machine 10, a prize drop opening 20 is provided horizontally. In the crane game machine 10 according to the present embodiment, a prize drop opening 20 is provided over almost the entire width of the casing, and a prize drop opening for a player who plays the left half on the left side and a player who plays the right half on the right side. 20 is used. In the vicinity of the boundary with the prize drop 20 on the prize field 16, a prize drop guard 22 is provided. The prize drop guard 22 supports the prize loaded in the prize field 16 so as not to fall into the prize drop opening 20.

  Above the left and right prize fields 16, crane arms 18 whose operations are controlled by player operations are mounted via mechanisms that operate the crane arms 18.

  On the front side of the lower housing 13, a prize outlet 21 and a panel part 23 that is operated by a player are provided. The prize take-out port 21 is for taking out a prize from the inside of the casing (prize field), and communicates with a prize dropping port 20 provided in the casing. By operating the crane arm 18, the prize is dropped to the prize dropping port 20, whereby the prize can be taken out from the prize taking-out port 21.

  The control panel 23 is provided with a joystick 24 and buttons 25 for operating the crane arm 18, a coin slot 26, a display device 27 (for example, a 7-segment display), and the like. In addition, a speaker is provided for outputting sound effects, music, message sounds, and the like during game execution (not shown).

  Above the prize field 16 in the upper housing 12, the crane arm 18 and the crane arm 18 are moved above the prize field 16, for example, in the X-axis direction, the Y-axis direction, and the Z-axis direction (vertical direction). A mechanism (not shown) is provided. When the crane arm 18 is moved to a predetermined position in the XY direction by a mechanism that operates in response to a player operation on the joystick 24 or the button 25, the crane arm 18 is moved downward in order to hold a prize on the prize field. Two gripping claws 18a (arms) for gripping prizes are provided at the tip of the crane arm 18 (three or four gripping claws 18a may be provided). The operation of the gripping claws 18a is controlled so as to be closed (gripping an object) at a position where the crane arm 18 is lowered to reach the prize.

  In the crane game machine 10 according to the present embodiment, a seesaw plate 19 is provided above the prize drop opening 20. In the configuration example shown in FIG. 1, a fulcrum is provided at the center in the lateral direction of the housing, and both ends of the seesaw plate 19 are moved up and down. That is, the seesaw plate 19 is inclined in the direction of either the prize drop 20 for the right player (first prize drop) or the prize drop 20 for the left player (second prize drop). Can do. A premium can be placed on the seesaw plate 19. The seesaw plate 19 is kept in a horizontal state when the left and right balance is achieved by the prize placed, but for example, a prize acquired from the prize field 16 by operating the crane arm 18 is applied to the seesaw plate 19. If the balance between the left and right is lost due to the addition, the side on which the prize was added falls and tilts. As a result, the prize placed on the seesaw plate 19 is dropped into the prize drop opening 20.

  In the crane game machine 10 shown in FIG. 1, a prize drop opening 20 is provided in a horizontally long manner on the front side (player side) of the crane game machine 10, and the left half operates a left panel control unit 23. The right half is used as a prize drop opening 20 for a player who is operating the left panel unit 23. Therefore, by providing the fulcrum of the seesaw plate 19 in the center, whether the prize placed on the seesaw plate 19 is dropped to the left side or the right side of the prize dropping port 20 is set to the left and right panel parts 23, respectively. You can contend between the two players operating.

  It should be noted that the installation position, size, length, etc. of the seesaw plate 19 can be arbitrarily determined according to the installation position and shape of the prize drop opening 20.

  FIG. 2 is a block diagram showing a functional configuration of the crane game machine 10 according to the present embodiment. The crane game machine 10 is realized by installing a computer function. Note that FIG. 2 shows only components that are operated by one player.

  As shown in FIG. 2, the crane game machine 10 includes a central control device 30, a storage unit 31, an arm control unit 33, an input control unit 34, and an output control unit 35.

The central control device 30 is constituted by a processor, a memory, and the like, and controls the crane game machine 10 as a whole. The central controller 30 realizes various functions by executing various programs stored in the storage unit 31.
The storage unit 31 is configured by a hard disk device or the like, and stores various programs and data.

  The arm control unit 33 controls driving of the X-axis motor 42, the Y-axis motor 43, the Z-axis motor 44, and the arm motor 45 under the control of the central control device 30. The arm control unit 33 selectively drives the X-axis motor 42, the Y-axis motor 43, and the Z-axis motor 44 in accordance with, for example, the player's operation on the joystick 24 to move the crane arm 18, and the arm motor 45 is moved. The gripping claw 18a is operated so as to grip the prize placed in the prize field 16 by driving.

  The input control unit 34 controls input from various input devices, controls input from the joystick 24, button 25, and coin sensor 46, and notifies the central controller 30 of input data. The coin sensor 46 is installed in the passage of coins inserted from the coin insertion slot 26 and detects a coin inserted from the coin insertion slot 26 (or the type of coin inserted).

  The output control unit 35 controls audio output from the speaker 49, display by the display device 27 (remaining play time, number of credits, various messages, etc.) and the like under the control of the central control device 30.

  3 and 4 are diagrams for explaining the arrangement of the seesaw plate 19. FIG. 3 is a plan view seen from above the prize field 16 inside the housing, and FIG. 4 is a perspective view.

  As shown in FIGS. 3 and 4, the seesaw plate 19 is attached above the prize drop opening 20. The seesaw plate 19 is arranged along a prize drop opening 20 that is configured to be horizontally long, and is shorter than the width of the prize drop opening 20. For this reason, the prize can be dropped in the vicinity of the both ends of the prize drop opening 20 that is not covered by the seesaw plate 19 (the first prize drop opening and the second prize drop opening).

  As shown in FIG. 4, the seesaw plate 19 is supported by a fulcrum mechanism 60 provided at the center in the lateral direction of the casing, and both ends thereof are moved up and down on the prize drop opening 20.

  FIG. 5 is a diagram showing a detailed configuration of the fulcrum mechanism 60 of the seesaw plate 19. For example, the fulcrum mechanism 60 is divided into two parts. The fulcrum mechanism 60 is configured to be separated into two parts, and the rotation shaft members 60a and 60b fixed to the bottom of the seesaw plate 19 and the support base 62a that rotatably supports the rotation shaft members 60a and 60b. , 62b. In the example shown in FIG. 5, the fulcrum mechanism 60 is divided into two parts, and the seesaw plate 19 is supported by the two rotary shaft members 60 a and 60 b. The structure attached with the support stand may be sufficient.

  The rotary shaft members 60a and 60b are rotatably supported by the support bases 62a and 62b, respectively. The support bases 62a and 62b support the shaft portions at both ends of the rotary shaft members 60a and 60b so as to be sandwiched so as to be rotatable. Screws 65 that penetrate from the outside to the shafts of the rotary shaft members 60a and 60b are attached to the support bases 62a and 62b. The screw 65 is used to adjust the braking force applied to the rotary shaft members 60a and 60b.

  The screw 65 penetrating the support base 62a can be switched between a fixed state and an open state with respect to the support base 62a. When adjusting the braking force, the screw 65 is opened to enable the screw 65 to rotate. At the time of game operation after the adjustment is completed, the screw 65 is fixed. By fixing the screw 65 to the support base 62a, the rotary shaft member 60a is braked by the braking function provided inside the rotary shaft member 60a via the screw 65. That is, the ease of tilting of the seesaw plate 19 can be changed by adjustment with the screw 65. As a result, for example, even if there is only one difference in the number of prizes placed on the left and right of the seesaw plate 19, it can be easily inclined, or if there are not a plurality of differences, it can be prevented from being inclined.

FIGS. 6A and 6B are diagrams illustrating an example of a braking function provided in the rotary shaft member 60a. In addition, the detailed description is abbreviate | omitted as the rotating shaft member 60b being the same structure as the rotating shaft member 60a.
As shown in FIGS. 6 (A) and 6 (B), the rotary shaft member 60a is hollow, and one end of a spring 67 is attached to the hollow inner bottom portion where the screw 65 is not penetrated. The end is attached to a screw 66 that engages the screw 65. Since the position of the screw 66 changes in the axial direction by turning the screw 65, the length of the spring 67 can be changed, that is, the tensile strength by the spring 67 can be adjusted.

  As shown in FIG. 6A, for example, when the length of the spring 67 is set to the state A, the spring 67 is strongly pulled, so that a large braking force acts on the rotation of the rotary shaft member 60a. For this reason, even if a prize is placed on the seesaw plate 19, it is difficult to tilt.

  On the other hand, when the position of the screw 66 is changed by rotating the screw 65 and the length of the spring 67 is set to a B state shorter than the A state as shown in FIG. Since the pulling of 67 becomes weak, a small braking force acts on the rotation of the rotating shaft member 60a. For this reason, when a prize is placed on the seesaw plate 19, it is easy to tilt.

  Since the spring 67 is an elastic member, if the prize placed by the seesaw plate 19 inclining falls, it will return to its original state. For this reason, the seesaw plate 19 recovers to a horizontal state after dropping the prize.

  In this way, by making it possible to adjust the ease with which the seesaw plate 19 is inclined, it is possible for the administrator to adjust the ease with which the prize placed on the seesaw plate 19 is acquired. Therefore, it can be used for adjusting the payout rate. In addition, since the prizes handled by the crane game machine 10 have various sizes and weights, the prizes can be adjusted according to the types of prizes placed on the prize field 16 or the seesaw plate 19. For this reason, it is possible to improve the player's willingness to challenge the game by making the inclination easy according to the prize.

  In the configuration shown in FIG. 6, the spring 67 is provided to realize the braking function, but other elastic members can also be used. For example, elastic rubber or plastic may be used to function similarly to the spring 67. Further, as shown in FIG. 6, the configuration is not limited to the configuration in which the elastic member (spring 67) is housed in the rotary shaft member 60a. For example, the seesaw plate 19 (or the rotary shaft member 60a integrated with the seesaw plate 19) is used. ) And the fixed support base 62a are connected by an elastic member to define the positional relationship between the seesaw plate 19 and the support base 62a, and the same effects as described above can be obtained.

FIGS. 7A and 7B are diagrams illustrating an example of a braking function provided in the rotary shaft member 60a.
In the configuration shown in FIGS. 7A and 7B, a screw hole is formed in the rotary shaft member 60a, and a brake pad 69 is provided at a position where the screw 65 reaches. When the brake pad 69 comes into contact with the screw 65, the brake pad 69 acts to brake the rotary shaft member 60a by friction.

  Therefore, as shown in FIG. 7A, by screwing the screw 65 deeply, the contact surface between the screw 65 and the brake pad 69 becomes large, and a large braking force acts on the rotation of the rotary shaft member 60a. . For this reason, even if a prize is placed on the seesaw plate 19, it is difficult to tilt.

  On the other hand, as shown in FIG. 7B, by making the screw 65 shallow, the contact surface between the screw 65 and the brake pad 69 becomes small, and a small braking force is applied to the rotation of the rotary shaft member 60a. work. For this reason, when a prize is placed on the seesaw plate 19, it is easy to tilt.

  Thereby, it is possible to adjust the ease of inclination of the seesaw plate 19 by adjusting the screw 65 in the same manner as in the configuration shown in FIGS. In the configuration shown in FIGS. 7A and 7B, the prize is not restored to the horizontal state after the prize has dropped from the seesaw plate 19, but can be realized with a simple configuration.

Next, the effect of the crane game machine 10 in this embodiment is demonstrated.
In the crane game machine 10 according to the present embodiment, a prize is placed on the seesaw plate 19 by an administrator. The number of prizes placed on the seesaw plate 19 can be arbitrarily adjusted by the manager based on the size, weight, unit price, etc. of the prize.

  For example, as shown in FIG. 8, prizes are placed in advance so that the right and left sides of the seesaw plate 19 can be balanced (maintain a horizontal state). In the example shown in FIG. 8, a plurality of prizes 70 of the same type are placed, so that the same number of prizes 70 are placed on the left and right in the same arrangement and balanced.

  The player inserts coins from the coin insertion slot 26 when attempting to play a game. When the coin sensor 46 detects that a coin has been inserted, the central control device 30 starts game control.

  The central controller 30 drives the X-axis motor 42 and the Y-axis motor 43 through the arm control unit 33 when the operation of the crane arm 18 is instructed by the player's operation on the joystick 24 or the button 25, and the crane arm 18. Is moved horizontally on the prize field 16.

  In order to acquire a prize placed in the prize field 16, the crane arm 18 is moved horizontally (XY direction) to the target prize. Thereafter, the central controller 30 drives the Z-axis motor 44 through the arm controller 33 to lower the crane arm 18 to a position where it reaches the prize, and drives the arm motor 45 to grip the prize with the gripping claws 18a. After operating so as to close, the crane arm 18 is moved upward. Then, the central control device 30 moves the crane arm 18 to above the prize drop opening 20. At this time, the central control device 30 first moves the prize drop opening 20 to the upper side where the seesaw plate 19 is installed, and then moves it along the prize drop opening 20. For example, the crane arm 18 provided on the right side of the crane game machine 10 is moved from the left side where the seesaw plate 19 of the prize dropout 20 is provided to the right side.

  The central control device 30 operates to open the gripping claws 18a of the crane arm 18 at that time, for example, when the button 25 is pressed by the player while the crane arm 18 is moved above the prize drop opening 20. In other words, if the prize is being gripped by the crane arm 18, the player can specify the position where the prize is dropped by operating the button 25.

  When the button 25 is not operated, the central control device 30 determines the position of the prize drop opening 20 where the seesaw plate 19 is not provided (for example, the prize drop opening 20 in the crane arm 18 provided on the right side). After moving to the right end), the gripping claw 18a is operated to open. In other words, if the prize is being gripped by the crane arm 18, the prize can fall to the prize dropping port 20 and can be taken out from the prize outlet 21.

FIGS. 9 and 10 are diagrams showing a series of situations when the prize 72 is dropped from the crane arm 18 to the seesaw plate 19.
For example, as shown in FIG. 9, it is assumed that the prize 72 is dropped to the right side of the seesaw plate 19 by operating the crane arm 18. In this case, since the right side of the seesaw plate 19 becomes heavy, the seesaw plate 19 is inclined to the right side. Therefore, the plurality of prizes 70 placed on the left side of the seesaw plate 19 also slide on the seesaw plate 19 and move to the right side.

  As a result, the plurality of prizes 70 originally placed on the seesaw plate 19 and the prizes 72 newly acquired by the crane arm 18 all fall to the right side of the prize dropping port 20. Thereby, the player who was playing on the right side of the crane game machine 10 can acquire a plurality of prizes 70 and 72 collectively.

  When the seesaw plate 19 is adjusted so as not to easily tilt, the seesaw plate 19 does not tilt only by dropping one prize 70 on the seesaw plate 19 as described above. In this case, it is possible to inspire the player to challenge the player to drop the prize on the seesaw plate 19 by operating the crane arm 18.

  Further, if the rotary shaft member 60a is configured as shown in FIG. 6, after the prize is dropped from the seesaw plate 19, the seesaw plate 19 automatically recovers to a horizontal state. Then, as described above, the crane arm 18 performs the operation of gripping the prize in the prize field 16 and then moves it so as to pass above the seesaw board 19, so that the seesaw board 19 can be moved regardless of the player's intention. The prize may be dropped, and the prize can be put on the seesaw plate 19 again. Thereby, the operation | work which an administrator mounts a prize on the seesaw board 19 can be reduced.

  In this way, in the crane game machine 10 according to the present embodiment, a prize can be placed on the seesaw plate 19 provided above the prize drop opening 20, and the prize acquired by the crane arm 18 is stored. When the seesaw plate 19 is dropped, the seesaw plate 19 can be tilted so that a plurality of prizes placed on the seesaw plate 19 can be dropped together into the prize drop opening 20. Accordingly, a plurality of prizes can be provided collectively to the player without the administrator performing a task of stacking prizes in a special form. Further, this can be realized by a simple configuration in which the seesaw plate 19 is inclined by the fulcrum mechanism 60.

  Further, in the crane game machine 10 in which two players can play at the same time, the seesaw plate 19 is arranged by arranging the fulcrum mechanism 60 so that both ends of the seesaw plate 19 are positioned at the prize drop opening 20 for each player. It is possible to provide a new way to enjoy the prize placed between the two players.

Next, another configuration example of the fulcrum mechanism that supports the seesaw plate 19 will be described.
FIG. 11 is a perspective view showing the peripheral structure of the fulcrum mechanism 80 that supports the seesaw plate 19. As shown in FIG. 11, the fulcrum mechanism 80 is provided at the center in the lateral direction of the housing. Both ends of the seesaw plate 19 are configured to move up and down above the left and right prize drop openings 20a and 20b.

  An adjustment hole 81 for adjusting the inclination strength of the seesaw plate 19 is provided in the center of the upper surface portion of the seesaw plate 19. For example, by inserting a screwdriver into the adjustment hole 81 and rotating the adjustment shaft provided inside the housing of the fulcrum mechanism 80, the braking force on the seesaw plate 19, that is, the inclination when the prize 70 is placed. You can adjust the ease.

  By adjusting the braking force to the seesaw plate 19, the seesaw plate 19 can be inclined even when the balance of the prize 70 placed on the left and right of the seesaw plate 19 is slightly lost as shown in FIG. , And vice versa.

  FIGS. 13A, 13 </ b> B, and 13 </ b> C are diagrams illustrating a detailed configuration inside the fulcrum mechanism 80. 13A is a side view, FIG. 13B is a front view of a cross section taken along line AA in FIGS. 13A and 13C (viewed from the front of the player), and FIG. It is a top view of the cross section by the BB line of FIG. 13 (A) (B). In addition, when the fulcrum mechanism 80 is mounted in the crane game machine 10, the side surface side shown to FIG. 13 (A) shall also be covered.

  The horizontal cross section of the housing 82 has a substantially rectangular shape as shown in FIG. The seesaw plate 19 is connected to the upper portion of the housing 82 via a shaft member 84 for rotatably connecting the seesaw plate 19 at both ends in the longitudinal direction. The seesaw plate 19 can be inclined with the shaft member 84 as a fulcrum.

  A shaft support member 86 is fixed to the inner side surface of the housing 82 via a fixing member 87. The shaft support member 86 supports the adjustment shaft 88 so as to be vertical. An adjustment hole 81 is provided in the seesaw plate 19 immediately above the adjustment shaft 88.

  The adjustment shaft 88 is supported by a shaft support member 86 so as to be rotatable by a driver inserted from the adjustment hole 81, and a groove 88 a (concave portion) that is engaged with the tip of the driver is provided at the top of the adjustment shaft 88. Yes.

  A spring adjustment member 90 is coupled to the adjustment shaft 88 so as to be slidable in the vertical direction. The spring adjustment member 90 is engaged with the adjustment shaft 88 and moves up and down as the adjustment shaft 88 is rotated.

  Two spring stopper members 92 having a predetermined length are horizontally attached to the spring adjustment member 90 along the longitudinal direction of the casing 82, that is, the axial direction in which the seesaw plate 19 is rotated by the shaft member 84. It has been. One end of a spring 94 that can be expanded and contracted is attached to the tip of each spring stop member 92.

  On the other hand, at the bottom of the seesaw plate 19, two connecting members 98 are fixed at a predetermined interval on a shaft on which the seesaw plate 19 rotates by a shaft member 84. In the vicinity of the lower end of the connecting member 98, two spring stoppers having a predetermined length along the axis on which the seesaw plate 19 is rotated by the shaft member 84 so as to be rotatable by the shaft member 97. 96 are mounted horizontally. The other end of the spring 94 is attached to the tip of each spring stop member 96. That is, the spring 94 is attached between the spring retaining member 92 and the spring retaining member 96.

  Since the spring stopper member 96 is attached to the seesaw plate 19 via the connecting member 98, the distance from the seesaw plate 19 is fixed. On the other hand, the spring stop member 92 is attached to the spring adjustment member 90. Since the spring adjustment member 90 moves in the vertical direction as the adjustment shaft 88 rotates, the spring stop member 92 also moves up and down as the spring adjustment member 90 moves in the vertical direction. Accordingly, the spring 94 attached between the spring stoppers 92 and 96 expands and contracts as the spring adjustment member 90 is moved in the vertical direction, and the tensile strength changes.

Next, the adjustment and action effect of the braking force by the fulcrum mechanism 80 will be described.
When adjusting the braking force by the fulcrum mechanism 80, as shown in FIG. 14, the driver 100 is inserted from the adjustment hole 81 provided in the center of the seesaw plate 19, and the tip of the driver 100 is the groove of the adjustment shaft 88. 88a is engaged.

  Here, as shown in FIG. 15, when the adjustment shaft 88 is rotated counterclockwise by the driver 100, for example, the spring adjustment member 90 moves downward as the adjustment shaft 88 rotates. Thereby, the spring 94 attached between the spring stopper members 92 and 96 is extended.

  In this case, since the spring 94 is strongly pulled, a large braking force acts on the rotation of the seesaw plate 19. For this reason, even if the prize 70 is placed on the seesaw plate 19, it is difficult to tilt.

  On the other hand, as shown in FIG. 16, when the adjustment shaft 88 is rotated clockwise, for example, by the driver 100, the spring adjustment member 90 moves upward as the adjustment shaft 88 rotates. As a result, the spring 94 attached between the spring stoppers 92 and 96 contracts.

  In this case, since the tension of the spring 94 is weakened, a small braking force acts on the rotation of the seesaw plate 19. For this reason, when the prize 70 is placed on the seesaw plate 19, it becomes easy to incline.

  As described above, in the fulcrum mechanism 80 shown in FIGS. 11 to 16, in addition to the same function and effect as the case where the fulcrum member 60 shown in FIGS. The adjustment work can be facilitated by inserting the driver 100 into the hole 81 so that the braking force can be adjusted.

  In the fulcrum mechanism 80 as well, the spring 94, which is an elastic member, is used, and the two connecting members 98 are fixed on the shaft on which the seesaw plate 19 is rotated by the shaft member 84. Therefore, the seesaw plate 19 is inclined. When the prize 70 placed in step S3 falls, the seesaw plate 19 can be restored to the horizontal state by the action of the spring 94.

  Further, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
