In addition to amusement facilities such as so-called game centers, in addition to amusement facilities such as so-called game centers, the gamers (hereinafter also referred to as players) are motivated by using characters that are interesting and popular with prizes. Many are installed in malls. Conventionally, various kinds of prize acquisition game apparatuses have been proposed and commercialized.

  As the prize acquisition game apparatus as described above, for example, an apparatus having a UFO-like shape (hereinafter referred to as a prize acquisition unit) provided with a pair of open / close arms with claws is often used. In this case, the prize acquisition unit first moves horizontally within the housing in response to the player's operation, and then moves to the position immediately below the position and then opens and closes the arm, and further above the prize receiving port. Move and open and close the arm again. During such a series of operations, for example, if the prize is grasped and lifted by using a claw at the tip of the arm and can be carried without dropping to just above the prize receiving port, the prize can be obtained.

  Patent Document 1 discloses an arrival time detection means that detects the tension of the wire (21) generated by the weight of the catcher (20) as a prize acquisition unit and detects the arrival of the catcher (20) at the position of the prize (12). A game apparatus (crane game machine (1)) including a microswitch (30) as a controller and a controller (31) for stopping the lowering drive operation of the driving means based on a detection signal detected by the microswitch (30). It is disclosed. The fact that the prize acquisition unit descends and comes into contact with the prize or the like is detected using the looseness of the wire (21) at that time.

  In such a prize acquisition game device, the prize acquisition unit is lowered by sending out a wire that suspends the prize acquisition unit, and when the prize acquisition unit abuts on the prize or reaches the floor, There is one that detects the looseness to stop the rotation of the motor that sends out the wire, stops the lowering of the prize acquisition unit, and starts the gripping operation. There has also been proposed an apparatus that can further press down the prize acquisition unit even in a situation where a reaction force greater than its own weight is applied to the prize acquisition unit while suppressing an increase in the weight of the prize acquisition unit. (For example, refer to Patent Document 2).

  In Patent Document 3, a threshold for detecting a stress level (pressing pressure) generated when the catcher portion (14) is moved downward and pressed against a prize or the like is set in advance. A game device (premium acquisition game machine) is disclosed. When the control unit (30) in this game apparatus detects that the stress level detected by the stress sensor (37) has reached a preset threshold, the catcher unit (14) moves downward. Stop. In addition, the game device has a constant force to press the prize downward when the catcher part descends and comes into contact with the prize, and has a threshold value of several steps on how much pressing force is applied after the contact. Yes.

  Patent Document 4 discloses a prize acquisition game device configured to change the speed at which the prize acquisition unit ascends and descends and presses the prize downward by impact energy when contacting the prize.

The upper end side of the pipe 11a is fixed to the gift acquisition unit base 12, and the pipes 11b, 11c, and 11d slide so as to be movable up and down. A boss 35a of the coupler 35 is fitted and fixed to the lower end of the lowermost pipe 11d. The prize acquisition unit 4 is connected to the end of the coupler 35 via a bracket 36 (see FIGS. 6 and 10). In the state where the prize acquisition unit 4 is on the upper side, the loads of the nested pipes 11b, 11c, and 11d are applied to the prize acquisition unit 4. As the prize acquisition unit 4 descends, the stopper 22 of the pipe 11b reaches the lower end of the groove 23 of the pipe 11a, whereby the load of the pipe 11b is supported by the pipe 11a, and subsequently the load of the pipe 11c is supported by the pipe 11b. After that, the load of the pipe 11d is supported by the pipe 11c. Accordingly, when descending, the loads of the pipes 11b, 11c, and 11d act on the prize acquisition unit 4, and the pipe loads are suspended on the pipe 11a in the order of the pipes 11b, 11c, and 11d as the prize acquisition unit 4 descends.

  Further, an elevating device 37 as an elevating means for elevating the prize acquisition unit 4 up and down is wound by a take-up / rewind device 39 mounted on the gift acquisition unit base 12 and the take-up / rewind device 39. The wire 40 is taken. The wire 40 passes through the inside of the support portion 11 (see FIG. 7). The winding / rewinding device 39 includes a wire motor 41, a reduction gear mechanism (not shown) including a worm gear, a wire winding pulley 42, and a descending stop device 43. When the prize acquisition unit 4 is lowered to the lowermost part, the load of the three pipes 11a, 11b, and 11c is not applied to the prize acquisition unit 4, and the load applied to the wire 40 is the prize acquisition unit 4 and the lowermost pipe 11d. And only some load on the cable 64.

  The descent stop device 43 is based on a change in the tension of the wire 40 (for example, a decrease in tensile force when slack occurs) when the prize acquisition unit 4 descends and collides with or touches the bottom of the prize P or the play field 3. It is a device that detects that the prize acquisition unit 4 is in a bottomed state and stops the lowering of the prize acquisition unit 4 based on the detection signal (S3). For example, the descent stop device 43 in this embodiment includes a swing arm 47 that can swing around the dog rotation shaft 46, a lift-down sensor dog 47 a, and a tension pulley 45 that is rotatably supported by the swing arm 47. A coil spring (torsion spring) 48 that urges the swing arm 47 in the direction of lifting the prize acquisition unit 4 so as to press the tension pulley 45 against the wire 40, and a lift-down sensor 55. (Refer to FIG. 10 etc.).

  In addition, although the apparatus which stops the descent | fall of the prize acquisition part 4 based on the detection signal (S3) that the prize acquisition part 4 became the bottom state was illustrated as the descent stop apparatus 43 here, this is a suitable example However, the descent stop device 43 having a configuration other than this can be used. For example, the rotation time or the number of rotations of the wire motor 41 corresponding to the descending amount until the prize acquisition unit 4 is in a bottomed state is stored in advance, and the gift acquisition is performed using the rotation time or the number of rotations of the wire motor 41 as a parameter. The unit 4 may control the lowering.

  The wire 40 is fed out from the wire take-up pulley 42, passes through one side of the tension pulley 45, is introduced into the inside of the support portion 11, and is a cylindrical shape that can move up and down in the pipe at the outlet end of the pipe 11d. The connector 63 is coupled. The connector 63 has a receiving hole 63a at the center, and the upper end of a mandrel 62 having a switch actuator 61 fixed to the lower end is coupled to the receiving hole 63a (see FIG. 7). Note that reference numeral 64 in FIG. 7 denotes a cable for supplying power to the motor 74.

  The tension pulley 45 is pressed against the wire 40 connected to the prize acquisition unit 4 and is urged by a coil spring 48 via a swing arm 47 in a direction to lift the prize acquisition unit 4 (lifting urging means).

  The lift-down sensor dog 47 a is a detected piece formed at the free end of the swing arm 47 and swings with the swing arm 47. A lift-down sensor 55 is disposed at the lowest point in the swingable range of the lift-down sensor dog 47a.

  The lift-down sensor 55 is composed of an optical sensor, for example, and detects whether the lift-down sensor dog 47a is raised or lowered depending on whether the light is blocked.

  When the prize acquisition unit 4 collides with or touches the bottom of the prize P or the play field 3 and becomes a bottomed state, the tension of the wire 40 is loosened, so that the swing arm 47 swings upward by the action of the coil spring 48. . At this time, the lift-down sensor dog 47a that has shielded the lift-down sensor 55 also swings upward together, so that the bottom-down state can be detected by the lift-down sensor 55.

  As another example of the detection of the bottomed state, the rotation time and the number of rotations of the wire motor 41 are taken into account in accordance with the height and position of the play field 3 and the prize throwing guide 17 and the size of the arm 8. May be determined in advance, stored in the storage unit 31, and detected from the operation of the wire motor 41.

(Suspending urging force changing means 90)
Furthermore, the prize acquisition game device 1 of the present embodiment includes a lifting biasing force changing unit 90. The lifting biasing force changing means 90 is a means for changing the biasing force in the lifting direction by the coil spring 48. The specific configuration of the lifting biasing force changing means 90 is not particularly limited, but the lifting biasing force changing means 90 in the present embodiment is configured by a movable holding plate member 91 and an adjustment knob 92 ( Refer to FIG.

  The movable holding plate member 91 is a plate-like member that is rotatably attached to the dog rotation shaft 46, and is arranged so that the end of the coil spring 48 contacts. Here, one end (fixed end) of the coil spring 48 is hooked and fixed on the swing arm 47, and the other end (free end) is hooked on the movable restraining plate member 91. (See FIG. 10 etc.). For this reason, when the movable holding plate member 91 is rotated about the dog rotation shaft 46, the urging force of the coil spring 48 (that is, the tension pulley 45 is pressed against the wire 40 in accordance with the amount of rotation, and the prize acquisition unit 4. The strength of the urging force when the oscillating arm 47 is urged in the direction of lifting the oscillating arm 47 changes.

  Here, the force to lift the wire 40 by the tension pulley 45 is a force smaller than the load of the prize acquisition unit 4 including the weight of the arm 8 (a force less than the weight of the prize acquisition unit). For this reason, in this embodiment, it is supposed that the load of the prize acquisition unit 4 including the arm 8 is less than the force of suspending the wire 40 by the tension pulley 45.

  Further, the force for suspending the wire 40 by the tension pulley 45 may be a force slightly smaller than the load of the prize acquisition unit 4 including the weight of the arm 8. In such a case, when the prize acquisition unit 4 is in a bottomed state, a load applied from the prize acquisition unit 4 (for example, a pushing force applied to the prize P from the prize acquisition unit 4) becomes minute.

  When the prize acquisition unit 4 reaches the bottom of the play field 3, as described above, the loads of the four pipes 11a, 11b, 11c of the support unit 11 are supported by the prize acquisition unit base 12. Thus, the load of these pipes does not act on the prize acquisition unit 4. In this embodiment, even if it becomes such a state, it sets so that it can descend | fall with the dead weight of the prize acquisition part 4 and the lowermost stage pipe 11d.

  The adjustment knob 92 is a member for changing the angle of the movable holding plate member 91, and includes a screw mechanism that displaces the position of the distal end portion 92a in accordance with the amount of rotation. The distal end portion 92 a is in contact with the outer surface of the movable holding plate member 91 and is pressed against the repulsive force of the coil spring 48.

  The adjustment knob 92 is preferably rotatably supported at two locations by, for example, a channel-shaped knob support member 93 attached to the side plate (exterior member) 12a of the prize acquisition unit base 12 (FIG. 11). , See FIG. Although not shown, of course, the adjustment knob 92 may be supported by the side plate (exterior member) 12a of the prize acquisition unit base 12 and the channel-shaped knob support member 93 attached to the inside of the side plate 12a. Good. In any case, the knob portion 92b of the adjustment knob 92 is positioned outside the side plate 12a (see FIGS. 11, 12, etc.). As described above, when the knob portion 92b of the adjustment knob 92 is located outside the side plate 12a, the manager of the prize acquisition game device 1 (for example, the service providing side user) can view the prize acquisition section base 12 from the outside. Since the adjustment knob 92 can be operated by picking the knob portion 92b, it is easy to change the urging force. In addition, according to the adjustment knob 92 including the screw mechanism, the urging force of the coil spring 48 can be changed steplessly.

(Biasing force changing operation using the lifting biasing force changing means 90)
The urging force changing operation using such a lifting urging force changing means 90 will be described.

  When the adjustment knob 92 is rotated forward to move the tip end portion 92a forward, the movable holding plate member 91 is pushed in, and the urging force of the coil spring 48 is increased to be in the “spring strength” state (see FIGS. 15 and 16). ). As a result, the biasing force of the coil spring 48 that biases the swing arm 47 in the direction in which the premium acquisition unit 4 is lifted increases. As a result, the premium acquisition unit 4 itself acts via the swing arm 47 and the wire 40. The urging force in the lifting direction will also increase.

  On the other hand, when the adjustment knob 92 is reversed and the tip end portion 92a is retracted, the movable holding plate member 91 returns to the adjustment knob 92, and the urging force of the coil spring 48 is reduced to a “spring weak” state. (See FIGS. 13 and 14). As a result, the urging force of the coil spring 48 that urges the swing arm 47 in the direction of lifting the prize acquisition unit 4 is reduced. As a result, the prize acquisition unit 4 itself acts via the swing arm 47 and the wire 40. The biasing force in the lifting direction is also reduced.

  If the urging force in the lifting direction acting on the prize acquisition unit 4 changes in this way, the magnitude of the pushing force acting on the prize P from the prize acquisition unit 4 when the bottomed state is reached also changes. Therefore, in the prize acquisition game device 1 of the present embodiment, the pushing force acting on the prize P can be appropriately changed by changing the biasing force of the coil spring 48. Hereinafter, a specific example will be described.

  In recent years, the layout of the prize P in the play field 3 has been diversified. For example, the prize P is hooked on the prize drop opening 17a, and the prize P is positively pressed downward by the prize acquisition unit 4. (See FIG. 8 and FIG. 9), a prize P wider than the opening of the arm 8 is set so that a part of the prize P protrudes from the prize mounting table 20, and a predetermined position of the prize P is defined. There is a layout (see FIG. 17 and the like) that can be obtained by tilting or shifting by pressing or the like and finally dropping it from the prize placing table 20. If the magnitude of the force when applying the pressing force from the prize acquisition unit 4 to the prize P can be appropriately changed according to the diversification of the layout, the operation and mode of the prize P at the time of pressing are changed. It is also possible to appropriately control the acquisition rate (so-called payout rate) of the prize P (see FIG. 8, FIG. 9, etc.).

  For example, when the biasing force of the coil spring 48 is reduced to a “spring weak” state as described above (see FIG. 13), the prize is acquired when the prize acquisition unit 4 is in a bottomed state (see FIG. 14). Since the urging force in the lifting direction acting on the acquisition unit 4 itself is reduced, the magnitude of the load acting on the prize P from the prize acquisition unit 4 is relatively increased. Therefore, if the “spring is weak” state, the pushing force is set to “strong” (see FIG. 18).

  On the other hand, when the urging force of the coil spring 48 is increased to the “spring strength” state (see FIG. 15), the prize acquisition unit 4 itself when the prize acquisition unit 4 is in a bottomed state (see FIG. 16). Since the urging force acting on the hoisting direction is increased, the magnitude of the load acting on the prize P from the prize acquisition unit 4 becomes relatively small. Therefore, if the “spring is strong” state, the pushing force is set to “weak” (see FIG. 19). Further, in the state where the pushing force is set to “weak” as described above, depending on the magnitude of the biasing force of the coil spring 48, it is possible to reduce the pushing force to less than the weight of the prize acquisition unit 4. The pushing force can be greatly reduced as compared with the weight of the prize acquisition unit 4.

  Further, as a prize acquisition game device, the size of the arm 8 can be freely changed in accordance with a change in the shape and size of the prize P, a layout change, a position change of the prize insertion guide 17 (premium drop opening 17a), and the like. (See FIG. 20). When the size of the arm 8 is changed, the total weight of the prize acquisition unit 4 also changes. In this regard, in the prize acquisition game device 1 of the present embodiment, when the total weight of the prize acquisition unit 4 changes, the prize acquisition unit 4 acts on the prize P by appropriately changing the biasing force of the coil spring 48. The pushing force to be adjusted can be adjusted.

  As described above, in the present embodiment, when the prize acquisition game device 1 is configured to positively press the prize P downward by the prize acquisition unit 4, in the present embodiment, the prize acquisition unit 4 presses the prize P. It is possible to reduce the pressure by adjusting the pressure, especially less than the weight of the prize acquisition unit. Further, even when the weight of the prize acquisition unit 4 is changed by changing the arm 8 or the like, the pressing force before the change can be adjusted. Moreover, for the manager of the prize acquisition game device 1 (for example, a service providing user), the adjustment knob 92 is operated by turning the knob portion 92b located outside the side plate 12a of the prize acquisition unit base 12. This eliminates the need for cumbersome operations such as removing and attaching the housing. Further, according to the suspension biasing force changing means 90 having the configuration using the screw mechanism as described above, the stepless adjustment can be made while finely changing so as to obtain a desired biasing force.

  Each of the above embodiments is an example of a preferred embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. For example, in the embodiment described above, the wire 40 is moved upward by using the swing arm 47 that can rotate around the dog rotation shaft 46 as a configuration for pressing the tension pulley (pressed member) 45 against the wire 40. Although energized (see FIG. 10 etc.), this is only an example of energizing the wire 40 in the direction of lifting. For example, if the wire 40 is not overwhelmed, a tension pulley that urges the wire 40 between the fixed pulley and the wire take-up pulley 42 downward as a pulley that fixes the tension pulley 45 may be provided. Furthermore, tension may be applied to the wire 40 in the horizontal direction. Further, as a method of urging the wire 40, tension by a tension spring that pulls the wire 40 may be applied. In addition, a mechanism using a member that moves linearly (for example, a mechanism that rotates a pinion by a rack that linearly moves by an amount corresponding to the looseness of the wire 40) may be used. In short, the method of movement of the member is not particularly limited as long as it is configured to be displaced according to the slackness of the wire 40 and to detect the slackness amount of the wire 40 based on the displacement amount.

  In addition, the suspension biasing force changing unit 90 in the above-described embodiment is an example of a stepless adjustment using an adjustment knob 92 including a screw mechanism, but other configurations may be used. . For example, a plurality of spring locking means such as a locking hole, a locking groove, or a locking projection are provided on the side plate 12a, and the position where the end 48a of the coil spring 48 is locked is manually positioned stepwise. In addition, the biasing force of the coil spring 48 can be changed according to the changed position (see FIG. 21). Such a lifting biasing force changing means 90 can be adjusted in several steps (several ways) and cannot be adjusted steplessly. However, the lifting biasing force changing means 90 can be constructed with a relatively simple configuration. There is an advantage that you can. Although the locking means is not specifically shown in FIG. 21, the point is to change the position stepwise by hooking the end of the coil spring 48 such as the above-described hole, groove, or protrusion. Anything is possible.

  Further, the suspension biasing force changing means 90 in the above-described embodiment is such that an administrator (for example, a service providing side user) of the prize acquisition game device 1 manually turns the knob portion 92b of the adjustment knob 92 or the coil spring 48. Although the configuration is such that the urging force is changed by positioning the end portion in stages, a configuration other than this may be used. Although a detailed description is omitted here, for example, a driving device (such as a motor) for rotating the screw mechanism such as the adjustment knob 92 in the forward and reverse directions is used, and the urging force is automatically controlled by instructing the driving device from the outside It is also possible to make adjustments possible.

  FIG. 22 is a graph showing a change example of the urging force by the control of the lifting urging force changing means 90 accompanying the lowering operation of the prize acquisition unit 4 shown in FIGS. 18 and 19. When the prize acquisition unit 4 is in the uppermost stage, the load on the prize acquisition unit applied to the wire 40 is the load of the prize acquisition unit 4 and the pipes 11b, 11c, 11d, and 11e. Next, when the upper end of the pipe 11b reaches the lower end of the pipe 11a, the load applied to the wire 40 becomes the load of the prize acquisition unit 4, the pipes 11c, 11d, and 11e. The load applied to the wire 40 by the descending of the prize acquisition unit 40 finally becomes the prize acquisition unit 4 and the pipe 11e.

  In the automatic adjustment of the urging force, the height at which the prize P is arranged has several levels, and when the load on the pipes 11b, 11c, 11d applied to the prize acquisition unit 4 at that height changes, However, it is effective to keep the pressing force of the prize acquisition unit 4 constant.

  In this case, since the height when the prize acquisition unit 4 is lowered can be detected from the number of rotations and the rotation time of the wire motor 41, the telescopic pipe 11b according to the height when the prize acquisition unit 4 is lowered, As the load applied to the prize acquisition unit 4 by the loads 11c and 11d decreases, the screw mechanism of the adjustment knob 92 is driven to reduce the force applied in the lifting direction, thereby reducing the prize acquisition unit 4 The pressing force by can be kept constant. Thereby, regardless of the height position of the prize P, the pressing force can be kept constant by the prize acquisition unit 4. When the prize acquisition unit 4 rises, control is performed to restore the urging force.

  Even when the height of the play field 3 is constant, the pressing force when the prize acquisition unit 4 is lowered can be changed according to the position of the play field 3 (horizontal front, back, left and right). In this case, by setting a pressing force in the storage unit 31 of the control unit 30 in advance for each horizontal position of the play field 3, the position of the gift acquisition unit base 12 is determined as the X-direction position detection means and the Y-direction position. By acquiring the coordinate data from the detection means, it is also possible to control the suspension biasing force changing means 90 to the pressing force set for each position of the play field 3.

  Moreover, the wire 40 is only an example for suspending the prize acquisition unit 4, and other members may be used. Similarly, the coil spring 48 is only a suitable example for pressing the tension pulley 45 against the wire (hanging member) 40, and other urging members may be used. In addition to such a coil spring 48, a device such as a torsion bar that can similarly apply a lifting biasing force can be used as the lifting biasing means.

  The present invention is suitable for application to a prize acquisition game apparatus, particularly a prize acquisition game apparatus having a configuration in which a prize is positively pressed downward by a prize acquisition unit.
