Description

[Technical Field]

[0001] The present invention relates to a prize acquisition game device such as a crane game. [Background technology]

[0002] In amusement facilities, etc., prizes such as stuffed toys are dispensed by operating the prize gripper. Increasing the gripping force of the prize gripping part makes it easier to carry the prize. The number of prizes dispensed increases, and weakening the gripping force of the prize gripper reduces the number of prizes dispensed. Therefore, a prize acquisition game device capable of adjusting the gripping force of the prize gripping part is has been proposed (see, for example, Patent Documents 1 and 2).

[0003] The crane game machine described in Patent Document 1 has a control unit that counts the number of prizes that can be won. The gripping force of the arm is changed so that the rate approaches a preset prize acquisition rate. More specifically, if the prize acquisition rate is below the target, the motor that opens and closes the arms is turned off. If the prize acquisition rate exceeds the target, the motor drive time is shortened. If the drive time is extended, the coil spring of the arm will stretch accordingly, and the gripping force will become stronger. become.

[0004] The game device described in Patent Document 2 has a pair of upper pressing parts that hold the base ends of multiple arms. a coil spring that biases the lower pressing member toward the upper pressing member; and a peripheral wall plate that restricts the movement of the upper pressing member. The arm moves up and down by the ball screw. The gripping force of the arm is applied to the upper pressing member. The force of the coil spring that follows the upper pressing member is determined by the force of the coil spring. When the coil spring approaches the upper pressing member, the coil spring is compressed and the gripping force of the arm increases. do.

[0005] The crane game machine described in Patent Document 1 monitors the prize acquisition rate and adjusts the motor drive time. The angle of each arm is not taken into account. The game device described in Patent Document 2 detects the positional relationship between a single upper pressing member and a coil spring. The force of the coil spring is adjusted by the In other words, in the prize acquisition game devices described in Patent Documents 1 and 2, each arm The gripping force of the prize gripping portion cannot be adjusted based on the opening and closing angle.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-29825 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-1430372 Summary of the Invention [Problem to be solved by the invention]

[0007] However, not all arms come into contact with the prize at the same time. The energy storage of the biasing member such as a coil spring that determines the gripping force of the arm starts from the arm that has stopped. The opening and closing angle of the arm varies depending on the time difference, and the gripping force of the arm changes depending on the opening and closing angle. The driving time of the drive source is adjusted based on the opening and closing angle of each arm. Without this, it is not possible to suitably adjust the gripping force of the arm. Therefore, the present invention is a device that can adjust the gripping force of the prize gripping part based on the opening and closing angle of each arm. The object of the present invention is to provide a prize acquisition game device. [Means for solving the problem]

[0008] One aspect of the present invention is a prize acquisition game having at least one prize gripping unit for gripping a prize. The gripping force of each prize gripping part is adjusted by a control part. The unit includes a single drive source, a plurality of arms, and a plurality of sensors. The driving force supplied from the arm is distributed to multiple arms. When the driving force is distributed, each arm The arms open and close. A sensor is installed on each arm. Each sensor The control unit detects the opening and closing angles of the corresponding arms. The driving of the single driving source is controlled based on the above.

[0009] According to this aspect, even if the opening and closing angles of the arms vary, the opening and closing angles can be adjusted. In a configuration in which a single drive source is used to open and close multiple arms, Instead of detecting the opening and closing angles of all the arms at once, Since the prizes are detected individually, the gripping force of the prize gripping portion can be suitably adjusted.

[0010] In the above embodiment, each prize gripping portion is connected to each arm, and when the arms are closed, and a spring seat member attached to each arm, which is rotated in the direction of closing the arms. The device may further include a coil spring that stores energy when the member moves.

[0011] According to this aspect, a coil spring is used as the biasing member interposed between the arm and the driving source. In the case of a coil spring, the opening and closing angle of the arm relative to the movement of the spring seat member can be adjusted. It is easy to grasp the biasing force stored as a delay. It may be a torsion coil spring that receives a torsional moment around the central axis from the Alternatively, the spring may be a tension coil spring that receives tensile stress in the expansion / contraction direction from the spring seat member.

[0012] In the above-mentioned embodiment, each prize gripping portion converts the rotational movement of the screw shaft into the linear movement of the nut. and a link mechanism connecting each arm to the nut. A single drive source rotates the screw shaft, and each arm moves in response to the linear movement of the nut. The door may be rotated in the opening or closing direction.

[0013] According to this aspect, a single feed screw and a link mechanism are combined to form a simple structure. The driving force of the drive source can be distributed to multiple arms. Since it can be configured at a low cost, it is particularly suitable for a prize acquisition game device with a small housing.

[0014] In the above aspect, the control unit is configured to adjust the opening / closing angle of the arm that is the largest in the closing direction. The driving of a single driving source may be controlled based on the above.

[0015] The arm with the largest opening and closing angle has a weaker grip than the other arms. When the arms grasp the prize, even if one arm has a strong grip, the other arm will grasp the prize from the opposite direction. If the gripping force of the supporting arm is weak, the prize will slip away and it will not be possible to grip it tightly. The arms with weak gripping strength have a large effect on the gripping strength of the prize gripping portion as a whole. The drive of the single drive source is controlled based on the opening and closing angle of the arm with the weakest gripping force. The gripping force of the holding portion can be suitably adjusted.

[0016] In the above aspect, when the number of arms is 2n+1, the control unit The drive of a single drive source is controlled based on the opening and closing angle of the arm that is the (n+1)th largest. If the number of arms is 2n, the control unit calculates the opening and closing angle of the arm with the nth largest opening and closing angle in the closing direction. angle, the opening and closing angle of the n+1th largest arm, or the opening and closing angle of the nth largest arm and n + the average value of the largest arm opening angle or the single drive source Drives.

[0017] Depending on the shape of the prize and the number of arms, the arm with the weakest gripping power may be used instead of the other arms. In this embodiment, if the number of arms is, for example, three, The gripping force of the prize gripping section as a whole is adjusted appropriately based on the opening and closing angle of the arm of the second gripping force. When the number of arms is four, for example, the third arm of the gripping force can be adjusted. The opening and closing angle of the arm of the first gripping force can be used as the basis, or the opening and closing angle of the arm of the second gripping force can be used as the basis. You can also use the average value of these as a standard. The gripping force of the gripping portion can be suitably adjusted.

[0018] In the above embodiment, the control unit is configured to adjust the arm that has the largest opening / closing angle in the closing direction to the other arms. A weighted average with a weight greater than the weight of the system is calculated, and a single The driving of the driving source may be controlled.

[0019] According to this aspect, the opening and closing angles of the plurality of arms, i.e., the gripping force, can be appropriately adjusted according to the opening and closing conditions. We carefully considered the weight of each opening and closing angle to match the shape of the prize and the number of arms, The gripping force of the prize gripping portion can be suitably adjusted.

[0020] In the above aspect, a prize dispense sensor is further provided to detect the number of dispensed prizes. The control unit may obtain a payout index based on the number of prizes paid out, and The driving of a single driving source may be controlled based on the above.

[0021] An example of a payout index is the payout calculated by dividing the purchase price of the prize paid by the amount invested. For example, if you purchase a prize for 500 yen and get it for 1000 yen, the payout rate is 5 According to this embodiment, the control based on the detection results of the multiple sensors described above is In the Amusement In facilities, operators frequently monitor the payout rate and manually control the gripping force of the prize gripper. There is no need to manually adjust the amount, which reduces the burden on the operator. The indicator is not limited to the payout rate, but may be the number of prizes paid out per unit time, etc. The dispensing index may be calculated by the control unit itself, or may be externally acquired via a network or the like. may be obtained from the department. [Effects of the Invention]

[0022] According to the present invention, the gripping force of the prize gripping portion can be adjusted based on the opening and closing angle of each arm. A prize acquisition game device can be provided. [Brief explanation of the drawings]

When a sensor dog (not shown) blocks the light, the nut 54 moves to the end of its movable range. It is also possible to detect contact of the sensor dog with a pressure-sensitive sensor. .

[0050] FIG. 7 is a block diagram showing an example of the internal configuration of the prize gripping unit 40. As shown in FIG. The control board 60 includes a control unit 61 and a storage unit 62. The memory unit 62 is not limited to the control board 60 mounted on the prize gripping unit 40, but may be any other memory unit. The structure 5 or the intermediate field structure 6 may include a substrate mounted thereon.

[0051] The storage unit 62 has the function of storing various programs and an operating system. The storage unit 62 is a work area in which the control unit 61 temporarily stores various data during processing. The storage unit 62 is realized by, for example, a ROM. The ROM may store various programs necessary for controlling the driving of the motor 42. ROM is a volatile memory such as DRAM. non-volatile memory such as mask ROM, and flash memory. It is composed of one of the following rewritable nonvolatile memories or an appropriate combination of these. It is done.

[0052] The control unit 61 can be realized by the functions of a CPU mounted on the control board 60, for example. The CPU loads the program stored in the ROM onto the memory of the storage unit 62 and executes it. By making the devices that make up the product gripping unit 40 realize various functions, other hardware can be A gripping force control unit that adjusts the gripping force of the prize gripping unit 40 in cooperation with the accessory unit and components. and an adjustment means for determining an adjustment index to be referred to when the gripping force control means is executed. The control unit 61 determines the payout amount based on the number of prizes paid out. The dispenser 610 may further include a dispense index calculation means 613 for calculating a dispense index.

[0053] FIG. 8 shows a procedure for controlling the driving of a single motor 42 based on a plurality of opening and closing angles α, β, and γ. 1 is a flowchart showing an example of the operation of the player when the operation of the first operation unit 31 is input. The prize gripping section 40 moves in response to the player's operation (step S1). When all of the steps are completed, the prize gripping unit 40 descends and closes the arms 43. (Step S2). The arm 43 stops when it comes into contact with a prize or closes to the limit angle. If the arm 43 is not stopped, the control unit 61 returns to step S2 and stops the arm 43. The closing operation is repeated (step S3).

[0054] On the other hand, if the arms 43 are stopped, the opening and closing angles of the respective arms 43 are detected (step S3). The control unit 61 (adjustment index determination means 612) determines whether the detected opening / closing angle is set by the operator. The adjustment index for the grip force is determined by applying the specified conditions (for example, the largest opening and closing angle) ( Step S5). The adjustment index for the gripping force is the angle of the arm with the largest opening and closing angle in the closing direction D1. The opening and closing angle α of the arms 43A is not limited to this, and conditions can be appropriately selected depending on the shape of the prize and the number of arms 43. can.

[0055] For example, if the number of arms 43 is 2n+1, the opening and closing angle in the closing direction D1 is the n+1th opening angle. For example, if the number of arms 43 is 2n, It may be the opening / closing angle of the (n+1)th largest arm 43, or the opening / closing angle of the (n+1)th largest arm 43 It may be the opening / closing angle of the arm 43 that is the n+1th largest. It may also be an average value of these.

[0056] For example, the arm 43A having the largest opening / closing angle in the closing direction D1 is the other arm 43B, The weighted average (w1×α+w2×β+w3×γ) / (w The control unit 61 (gripping force control) may calculate the weighted average value of the weighted average value. The control means 611) controls the single motor based on the adjustment index of the gripping force determined in step S5. The drive of the motor 42 is controlled (step S6).

[0057] Furthermore, the control unit 61 can also add a correction value such as a payout index to the main adjustment index. The control unit 61 (payout index calculation means) acquires a payout index based on the number of paid-out prizes. An example of a payout index is the payout rate, which is the number of prizes paid out divided by the amount of money inserted. The payout index is not limited to the payout rate, but may be the number of prizes paid out per unit time. The payout index may be calculated by the control unit itself, or may be obtained by the network. It may also be obtained from outside via a network or the like.

[0058] When adjusting the gripping force of the prize gripping portion 40 based on the payout index, the fields 18 and 19 are By dividing the field into multiple fields, the payout rate can be counted for each field, and the prize gripping portion 40 can be gripped. The force may be adjusted. Figure 9 shows an example in which the field 18 is divided into multiple areas. As shown in FIG. 9, areas 181-182 and areas 183-184 are filled. Field 18 may be divided into two.

[0059] Although not shown, the field 18 is divided into two areas, 181 to 183 and 184. The field 18 may be divided into two areas, an area 181 and areas 182 to 184. Good. Area 181, Area 182-183, and Area 184 are three fields. It can be divided into smaller parts. For example, it can be divided into smaller parts according to the number of prizes in stock. By reducing the area where you place the prizes and adding other prizes in the empty spaces, The prizes that have been collected can be arranged in a visually appealing way.

[0060] In the example shown in Figure 9, an additional physical partition is placed at the boundary of field 18. Setting up a physical partition makes it easier to understand visually. This prevents prizes from being mixed in adjacent areas, so the types of prizes are clearly separated. Furthermore, the gripping force is adjusted for each area as described above with reference to FIGS. 1 to 8. If so, the payout rate of prizes with different unit prices for each divided field will be considered and handled appropriately. It is possible to determine where the prize gripping part 40 is located in the area divided by the partition. The presence or absence of the prize is determined by a sensor provided in the horizontal movement mechanism of the prize gripping part 40 (not shown) or a sensor that performs horizontal movement. This can be determined from the number of steps in the stepping motor.

[0061] The prize acquisition game device 1 of this embodiment configured as above is driven by a single motor 42. The power is distributed to a plurality of arms 43. The prize gripping unit 40 can be configured compactly and inexpensively. Therefore, it is suitable for a prize acquisition game device 1 that is divided into two sections, upper and lower, and has small prize storage sections 16, 17. As shown in FIG. 5, since angle sensors 44 are provided on all the arms 43, Therefore, even if the opening and closing angles of the arms 43A, 43B, and 43C vary, the opening and closing angles of the arms 43A, 43B, and 43C can be adjusted. Since the angles α, β, and γ can be detected individually, the gripping force of the prize gripping portion 40 can be suitably adjusted. can be done.

[0062] When α>β>γ, for example, the largest opening / closing angle α among the opening / closing angles α, β, and γ is The drive of the motor 42 is controlled based on the above. The prize is grasped by a plurality of arms 43A, 43B, and 43C. When holding the object, even if the gripping force of one arm 43C is strong, the arm supporting it from the opposite direction If the gripping force of 43A and 43B is weak, the prize will escape and it will not be possible to grip it tightly. If the opening and closing angle of the arm 43A having the weakest gripping force is used as a reference, the driving force of the single motor 42 is This allows the gripping force of the prize gripping portion 40 to be suitably adjusted.

[0063] Depending on the shape of the prize and the number of arms 43, the arm 43A with the weakest gripping force may be used instead of the other arms. In some cases, it may be more preferable to use the arms 43B and 43C as the reference. For example, w1>w2>w3 Weighted average value with weights of (w1×α+w2×β+w3×γ) / (w1+w2+w3) The drive of the motor 42 is controlled based on the shape of the prize and the number of arms 43. By setting the weight of the closing angle in detail, the gripping force of the prize gripping portion 40 can be suitably adjusted. For example, The driving of the motor 42 may be controlled based on the arm 43 having a medium gripping force. The conditions for determining the number of arms 43 are not particularly limited and can be selected appropriately depending on the shape of the prize and the number of arms 43.

[0064] Next, referring to FIGS. 10 to 16, the cabinet 2 of the prize acquisition game device 1 of this embodiment will be described. The features will be explained below. First, the coin chute 25 will be explained with reference to FIGS. 10 and 11.

The coin slots 21 and 22 are located at the bottom of the cash box 26. The first coin slot 21 is located only in the side field structure 5. The second coin slot 22 is located on the left side of the front panel of the structure 5, and is located on the middle field structure It is located on the right side of the front panel of 6.

[0065] The prize acquisition game device 1 of this embodiment receives a coin inserted into the second coin insertion slot 22 on the upper level. It is equipped with a coin chute 25 that guides coins to a cash box 26 on the lower level. If the coin chute 25 is configured vertically, the coin will fall into the coin chute due to the impact of the coin falling. There is a risk of damage to the chute 25 or the cash box 26. 11, the first to third inclined portions 251, 252 that constitute the coin chute 25 are Both 52 and 253 have gradients δ, ε, and ζ to absorb the impact of the coin falling. In the illustrated example, the structure is such that ε>δ,ζ, and the first and second In the first and third inclined portions 251 and 253, the coins roll along the gentle gradients δ and ζ. In the second inclined portion 252, the coin slides down the steep gradient ε. This protects the Coin Chute 25 and Cashier from the impact of a direct drop of coins. This can prevent damage to the box 26.

[0066] Next, the locking structure of the front doors 11 and 12 will be described with reference to FIGS. 12 and 13. The front doors 11 and 12 have substantially the same shape and function, so the front door The front door 12 will be explained in detail, and the overlapping explanation of the front door 11 will be omitted. If the doors 11 and 12 are double doors, the front doors 11 and 12 may obstruct pedestrians while prizes are being replenished. do.

[0067] As shown in FIG. 12, in this embodiment, the front door 12 is positioned on the left side so as not to obstruct pedestrians. It is configured as a right-sliding door. If it is a left-sliding door type, it usually has a left sliding door and a right sliding door. However, as in this embodiment, the key cylinder is installed in two stages on the left and right sides. If the space is small, in addition to the key cylinder 27 that locks the left sliding door 12L, It is difficult to secure space for the key cylinder to lock the 12R. Since there are multiple fields, installing two key cylinders for each field would be costly. become.

[0068] Therefore, as shown in Figures 12 and 13, only the left sliding door 12L can be unlocked and locked from the outside. When replenishing prizes, the key cylinder 27 is attached to the left sliding door 12L. Unlock Linda 27 and slide the left sliding door 12L to the right. When placing prizes in the designated area, slide the right sliding door 12R to the left to replenish the prizes. For such cases, there is a locking mechanism on the inside of the right sliding door 12R that can be unlocked by hand. There is a structure 28.

[0069] As shown in FIG. 13, the lock mechanism 28 includes a lock bar 281 and a locking mechanism 282. It consists of a guide 282 that holds the device in an upright position and a hole 283 that fits into the lock bar 281. The lock bar 281 is lifted and removed from the hole 283, allowing the right sliding door 12R to be opened to the left. To lock the door, slide the right sliding door 12R to the right. When the right sliding door 12R is returned to its original position, it is guided by the guide 282 and the lock bar 281 falls into hole 283 under its own weight, and the right sliding door 12R is locked.

[0070] Next, the left side panel 13, the right side panel 14, and the back panel 15 are secured between the middle field structure 6.
