FIG. 5 is a perspective view of an example of the configuration of the attachment 100, viewed obliquely from above. FIG. 6 is a perspective view of the same configuration example as viewed obliquely from below. The attachment 100 includes an alternative portion 104 , a link mechanism portion 105 , a renewal mounting portion 120 , a renewal claw portion 122 and a base portion 124 .

The alternative portion 104 is a member that can be attached to the attachment portion 38 instead of the claw portion 9 . Specifically, one end has the same configuration as the base of the claw portion 9 (for example, a structure that engages with the retaining pin 38p), and the other end has a connection portion with the link mechanism portion 105 (link portion 110). have As a matter of course, the substitute portion 104 attached to the mounting portion 38 swings integrally when the mounting portion 38 is swung by the driving portion 40 .

The link mechanism part 105 is a mechanism that converts the swinging motion of the replacement part 104 attached to the attachment part 38 in the swinging direction into the gripping/ungrasping motion of the prize 4 by the plurality of renewal claws 122 . It has a member 106 and a link portion 110 .

The cross member 106 is a member provided along a direction crossing the swinging direction of the mounting portion 38 , and is prepared for each substitute portion 104 . Specifically, the cross member 106 is a rod-shaped member having an arc-shaped cross section when viewed from above.

The link portion 110 is a structural portion that links the crossing member 106 with the replacement portion 104 , and converts the rocking motion of the replacement portion 104 mounted on the mounting portion 38 in the rocking direction to the vertical movement of the crossing member 106 . Specifically, the link portion 110 includes a connecting rod 111 whose one end is supported by the alternative portion 104 so as to be able to swing vertically and whose other end is connected to the cross member 106, and a guide portion which guides the movement direction of the connecting rod 111. 113 and .

The guide portion 113 has a slit 113s that opens toward the outer edge portion. The connecting rod 111 is inserted through the slit 113s, and the slit 113s guides the vertical swing direction of the connecting rod 113s, thereby stabilizing the operation direction. Since the slit 113s is open in the outer edge direction, the connecting rod 111 can be swung and escaped outside when inserting and extracting the substitute portion 104 into and out of the mounting portion 38, resulting in good workability.

The renewal mounting portion 120 is a part for detachably mounting the claw portion 9 as the renewal claw portion 122 . In this embodiment, the mounting part for renewal 120 is attachable to and detachable from the pedestal part 124 . In this embodiment, the number of renewal mounting portions 120 is shown as two per one cross member 106 . However, originally, N pieces (N≧3) are prepared in advance for each cross member 106 so that the user can arbitrarily select the number to be attached to the pedestal 124 (the number to be used) within the range of 0 to N. It's becoming

FIG. 7 is a perspective external view of the mounting portion 120 for renewal and the pedestal portion 124 as viewed obliquely from above. FIG. 8 is a perspective external view of the mounting part 120 for renewal and the pedestal part 124 as viewed obliquely from below.

As shown in FIGS. 5 to 8, the renewal mounting portion 120 includes a swinging base portion 120j which is a portion for attaching and detaching to the lower surface of the pedestal portion 124, a fixing plate 120k extending from the swinging base portion 120j, and a swinging end portion 120y supported by a swinging shaft 120s of the swinging base portion 120j so as to be capable of swinging up and down.

The upper end of the swing base 120j forms a projection 120t that engages with a positioning hole 126h of a fixing portion 126 provided on the base portion 124. As shown in FIG.

The fixing plate 120k has an insertion hole through which a fixing bolt 126b (see FIG. 6) provided at the center of the base portion 124 in top view is inserted and tightened with a wing nut or the like. By fixing the fixing plate 120 k to the base portion 124 , the mounting portion 120 for renewal is fixed to the base portion 124 .

The swinging end portion 120y has the same configuration as the mounting portion 38, and the renewal claw portion 122 can be detachably inserted and removed. The swinging end portion 120y (renewal mounting portion 120) has an insertion hole portion 120h through which the cross member 106 is inserted. In other words, the mounting portion 120 for renewal has an insertion hole portion 120 h that functions as a part of the link portion 110 .

The hole diameter of the insertion hole portion 120h is set to be slightly larger than the diameter of the circular cross section of the cross member 106, and the contact position of the cross member 106 inserted through the insertion hole portion 120h can be freely moved along the arc shape. It can change. As a result, even if there are variations in machining accuracy and assembling accuracy of each part, the mounting part 120 for renewal can be moved up and down smoothly by swinging the replacement part 104 .

The renewal claw portion 122 is a claw portion for renewal that is connected to the cross member 106 to perform a gripping/ungrasping operation in accordance with the elevation of the cross member 106 . In this embodiment, the configuration is similar to that of the claw portion 9, and the claw portion 9 and the renewed claw portion 122 can be used interchangeably. Of course, the renewal claw portion 122 can also be designed as a dedicated part having a shape different from that of the claw portion 9 .

The pedestal portion 124 is a member serving as a base for mounting the attachment 100 on the driving portion 40 . Therefore, the upper surface of the pedestal portion 124 is provided with an engaging structure for attachment to and detachment from the lower surface of the driving portion 40 . In this embodiment, an engaging piece 125 is provided (see FIG. 5). The engaging piece 125 forms a gap between itself and the pedestal portion 124 for fitting the bent portion provided at the lower end of the drive portion 40 . Note that the engagement structure can be set as appropriate. It may be screwed to the drive unit 40 .

A guide portion 113 of the link portion 110 is attached to the upper surface of the pedestal portion 124 .

In addition, the pedestal portion 124 has a plurality of fixing portions 126 to which the mounting portion for renewal 120 can be attached, M locations (M >N).

Specifically, the fixing portion 126 has a positioning hole 126h and a fixing bolt 126b (see FIG. 6). The positioning holes 126h are provided radially from the center of the base portion 124 in a top view (see FIG. 7). In addition, the fixing|fixed part 126 is not restricted to the said structure. For example, a configuration is possible in which a screw hole for screwing the renewal mounting portion 120 is provided instead of the positioning hole 126h.

Next, the operation of the catch mechanism section 31 will be described.
As shown in FIG. 2, in the initial state at the start of game play, the catching mechanism section 31 is in a state where the renewal claw section 122 is open. At this time, in the catch mechanism section 31, as shown in FIG. 4(1), the mounting section 38 is in a state of being swung upward. The alternative portion 104 attached to the attachment portion 38 is in a state of being swung upward integrally with the attachment portion 38 .

Since the connecting rod 111 of the link portion 110 is connected to the alternative portion 104 at the pivot end side, when the alternative portion 104 is in a state of being pivoted upward integrally with the mounting portion 38, the connecting rod 111 and The cross member 106 is pulled upward and ready. Then, the renewal mounting portion 120 connected to the cross member 106 is in a state where the swinging end portion 120y is lifted, and the renewal claw portion 122 mounted thereon is also swung upward. At this time, if the attachment 100 and the catch mechanism portion 31 are viewed as a whole, the renewal claw portion 122 is in an open state.

When the user performs an operation input to move the acquisition mechanism section 30 to the lowered position, the acquisition mechanism section 30 automatically lowers the catch mechanism section 31 after moving according to the operation input under movement control by the control board 50 . Let Then, when the descent is performed, the catch mechanism section 31 is controlled to perform a gripping operation.

When the gripping operation starts, in the catch mechanism section 31, the motor 41 is driven to rotate in a predetermined direction by the control board 50, and the mounting section 38 swings downward. Then, the substitute portion 104 is also swung downward integrally with the mounting portion 38 . Then, when the alternative portion 104 is swung downward, the connecting rod 111 and the cross member 106 are lowered. Then, the swing end portion 120y of the renewal attachment portion 120 swings downward, and the renewal claw portion 122 attached thereto is swung downward.

FIG. 9 is a partial transition diagram for explaining the gripping operation of the catch mechanism portion 31, showing the renewal attachment portion 120, the renewal claw portion 122, and part (1) of the link portion 110. It is a top view and (2) a partial perspective view. The left side of the white arrow indicates the starting state of the grasping motion, and the right side of the white arrow indicates the state in the middle of the grasping motion.

In the gripping process, the crossing member 106, which is arc-shaped in top view, descends so as to draw an arc in side view, thereby changing the relative positional relationship between the crossing member 106 and the renewal mounting portion 120 during the gripping process. Specifically, the relative position where the crossing member 106 and the insertion hole portion 120h of the renewal attachment portion 120 come into contact with each other and the relative posture of the two change, and the positions are separated from each other with the connecting rod 111 of the link portion 110 as a reference. Misalignment occurs. In FIG. 9(1), the black band portion of the cross member 106 shown in the state diagram during the gripping motion on the right side of the white arrow indicates the contact position at the start of the gripping motion (left side of the white arrow). Even if there is a change in geometry due to such gripping motion, the hole diameter of the insertion hole portion 120h is appropriately set so that the cross member 106 can be loosely fitted. The renewal claw portion 122 is swung smoothly.

Then, as shown in FIG. 4(2), when the mounting portion 38 swings downward until it reaches a predetermined angle, the control board 50 automatically stops the gripping operation. At this time, if the attachment 100 and the catch mechanism portion 31 are viewed as a whole, as shown in FIG. 10, the renewal claw portion 122 is in a closed state. Specifically, the plurality of renewal claws 122 are in a state in which the tips of the respective renewal claws are close to each other during the gripping operation.

When the grasping motion is finished, the catching mechanism 31 is pulled up to the original position again and moved to a designated position in the game space 6 (a position above the prize acquisition area where the prize placement area parts 18 are not attached), where the player ungrabs. Action is started.

When the unclamping operation starts, in the catch mechanism section 31, the control board 50 reversely drives the motor 41, the mounting section 38 swings upward, and the replacement section 104 swings upward integrally with the mounting section 38. . Then, when the substitute portion 104 swings upward, the connecting rod 111 and cross member 106 rise. Then, the swinging end portion 120y of the renewal attachment portion 120 swings upward, and the renewal claw portion 122 attached thereto is swung upward. That is, the tip of each renewal claw portion 122 is separated by the grasping and releasing operation.

When the ungrasping action is completed, the catch mechanism 31 is moved to a predetermined initial position within the game space 6, and one play ends.

As described above, according to the present embodiment, it is possible to realize a new prize acquisition device 10 capable of changing the number and position of attachment of claws for grasping a prize.

Moreover, if the attachment 100 and the exterior case 32 are prepared, conventional products can be used as they are up to the catch mechanism 31, so that the prize capturing device 10 of the present embodiment can be realized at low cost and low man-hours. In addition, since both the renewed claw portion 122 and the claw portion 9 can be used, the existing claw portion 9 can be used without newly preparing the renewed claw portion 122 .

Then, the user of the prize acquisition device 10 can set the catch mechanism 31 suitable for the size and shape of the prepared prize 4 by appropriately changing the number and position of attachment of the replacement mounting portion 120 to the pedestal portion 124 . will be able to do by themselves.

Specifically, as shown in the attachment 100B of FIG. 11, one of the two crossing members 106 is equipped with only one renewal claw portion 122, and the other is equipped with two renewal claw portions 122. Then, the catch mechanism portion 31 with three claws can be realized. Further, if two renewal claw portions 122 are attached to both of the two crossing members 106, the catch mechanism portion 31 having four claws can be realized. Depending on which fixing portion 126 the renewal claw portion 122 is attached and fixed to, the position to which the claw tip of the renewal claw portion 122 is separated in an open state can be freely set. At that time, the mounting position of the renewal claw portion 122 can be mounted and fixed in a symmetrical position on the left and right of both of the two cross members 106 (see FIG. 12), or it can be mounted and fixed in asymmetrical position on the left and right. (See FIGS. 5 and 6).
