[0002]

2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine, when a game ball in an upper plate becomes full, or when ending a game, an operating body arranged near the upper plate is opened. , A ball extracting device is provided so as to extract the game balls on the upper plate to the lower plate. Conventionally, this ball extracting device is provided with an opening / closing plate for opening and closing the extraction hole of the upper plate, and an urging spring for urging the opening / closing plate in the normally closed direction. Generally, a normally-closed type in which a user slides an opening / closing plate in an opening direction against an urging spring by an operating body.

[0003] However, the normally closed ball extracting device has a drawback in that the operation body must be continuously operated in the opening direction during the extraction of the game ball, and the operation is very troublesome. Therefore, the applicant of the present invention has conceived a toggle-type ball extracting device configured to bias the open / close plate in the closing direction when the open / close plate is at the closed position and in the open direction when the open / close plate is at the open position. ing.

[0004]

In this toggle type ball extracting device, once the operating body is operated in the opening direction to open the extracting hole, the opening / closing plate can be held at the open position.
It is not necessary to keep operating the operating body to the open position side during the removal of the game ball, and the operation is easier than the conventional normally closed ball removal device, and when removing the game ball during the game, Very convenient.

However, in the toggle type ball extracting device, it is necessary to return the opening / closing plate to the closed position by operating the operating body in the closing direction after operating the opening / closing plate to the open position and extracting the game ball. If the previous player left the game ball with the game ball removed, when the later player put the game ball in the upper plate, all the game balls will be pulled out from the extraction hole to the lower plate side through the extraction passage. There is a disadvantage.

70c are respectively locked to the first mounting portions 73.

In this toggle mode of use, FIG.
When the operating body 16 is positioned on the left end side of the operation hole 41 as shown in FIG. 7, the opening / closing plate 18 closes the extraction hole 21 at the closed position C. At this time, the spring force of the first urging spring 70 acts on the opening / closing plate 18 via the swing arm 17 and the interlocking arm 36 in the closing direction, and urges the opening / closing plate 18 to the closed position C to hold it. Therefore, the player operates the operating body 16
The opening / closing plate 18 does not move in the opening direction unless is operated in the opening direction.

When a large number of game balls are put into the storage section 23 of the upper plate 6 during a game, the game balls in the storage section 23 are guided in a line by the alignment section 24 and move downstream to open and close. Plank 18
Ball feeding means from the ball supply hole 27 along the upper inclined surface 18a
You will be guided to the 14 side. Then, when the player operates the firing handle 11 of the firing means 10, the firing means 10 operates to fire the game balls on the firing rail 13 one by one to the game board 5 side, and in conjunction with this firing operation. The ball feeding means 14 operates to supply the next game ball on the firing rail 13.

On the ball feeding means 14 side, as shown in FIG. 9, the ball feeding member 64 is lowered so that the game balls are prevented from falling at the entrance side of the ball feeding case 62. Therefore, when the player operates the firing handle 11 to operate the firing means 10, the ball receiving member 63 rises in conjunction with the firing operation, and the ball feed member 64 connected to the ball receiving member 63 rises. Therefore, the game ball on the entrance side of the ball feed case 62 falls on the ball receiving member 63. Then, when the ball receiving member 63 descends after the firing operation, the game balls on the ball receiving member 63 are supplied onto the firing rail 13, and at the same time, the ball feeding member 64 descends, and the next game ball is moved to the entrance side of the ball feeding case 62. Regulate with.

When the game balls in the upper plate 6 are full or when the game is finished, the game balls in the upper plate 6 are pulled out to the lower plate 8 side. Then, the player operates the operating body 16 in the opening direction (the direction indicated by the arrow a in FIG. 5). That is, the operating body 16 includes the sliding plate 46, the swing arm 17
When the opening / closing plate 18 is at the closed position C where the extraction hole 21 is closed, it is located on the left end side of the operation hole 69 as shown in FIG.

When the operating body 16 is operated in the direction indicated by the arrow a along the operation hole 69, the sliding plate 46 slides integrally with the operating body 16 in the direction indicated by the arrow a. Since the upper side of the swing arm 17 is operated in the direction of the arrow b through the interlocking pin 59 that engages with the engagement recess 60, the swing arm 17 swings about the pivot 53 in the direction of the arrow b, and 58, The opening / closing plate 18 is operated in the opening direction via the engaging pin 38.

Then, the sliding plate 46 slides in the direction of the arrow a integrally with the operating body 16, and the upper side of the swing arm 17 is moved through the interlocking pin 59 which engages with the engaging recess 60 on the lower side. Since the swing arm 17 is operated in the direction indicated by the arrow b, the swing arm 17 swings around the pivot 53 in the direction indicated by the arrow b, and operates the opening / closing plate 18 in the opening direction via the elongated hole 58 and the engaging pin 38. Therefore, the opening / closing plate 18 is guided by the sliding guide portions 39 and 40, and slides in the opening direction (the direction indicated by the arrow c) against the first biasing spring 70.

A locking portion 70 for locking the first biasing spring 70 to the swing arm 17 is located at an intermediate point of the sliding range of the opening / closing plate 18.
Until b reaches a line connecting the pivot 53 and the first mounting portion 73, the first urging spring 70 urges the opening / closing plate 18 in the closing direction. If you cancel the first
The opening / closing plate 18 automatically returns to the closed position C by the spring force of the urging spring 70.

However, the opening / closing plate 18 is in the open position O from the intermediate point.
When the locking portion 70b of the first urging spring 70 exceeds the line connecting the pivot 53 and the first mounting portion 73, the first urging spring 70
The urging direction of the opening / closing plate 18 is switched, and the first urging spring 70 urges the opening / closing plate 18 in the opening direction. Then, the opening / closing plate 18 slides to the open position O 1 by the spring force of the first biasing spring 70 to open the extraction hole 21 as shown in FIG. Therefore, the storage section of the upper plate 6
Arrangement of the game balls in 23, alignment hole 24, extraction hole 21, extraction passage
It can be pulled out to the lower plate 8 side through 20,21.

When the opening / closing plate 18 exceeds the intermediate point toward the open position O, the first urging spring 70 urges the opening / closing plate 18 in the opening direction. The open position O
The opening / closing plate 18 does not return to the closed position C even if the operating force on the operating body 16 is subsequently released. For this reason, even if it becomes necessary to remove the game balls in the upper plate 6 during the game, the user can concentrate on the game after operating the operating body 16 in the opening direction, which is very convenient.

After the game balls have been extracted, the opening / closing plate 18 is closed at position C.
To close the extraction hole 21, the operating body 16 is operated in the direction indicated by the arrow f in FIG. 13 until the opening / closing plate 18 exceeds the intermediate point. In this case, until the opening / closing plate 18 reaches the intermediate point,
Since the spring force of the first biasing spring 70 is acting in the opening direction,
The opening / closing plate 18 is slid against the first biasing spring 70.

However, when the opening / closing plate 18 exceeds the intermediate point toward the closing position C, the first biasing spring 70 biases the opening / closing plate 18 in the closing direction. Opening / closing plate 18
Slides to the closed position C, and the opening / closing plate 18 closes the extraction hole 21 as shown in FIG. For this reason, after the game balls in the upper plate 6 are extracted, if the operating body 16 is operated halfway in the closing direction, the opening / closing plate 18 is closed by the spring force of the first biasing spring 70.
Returning to C, the extraction hole 21 can be closed easily and smoothly.

Therefore, the operation of opening and closing the opening / closing plate 18 by the operating body 16 when removing the game ball from the upper plate 6 is much easier than before, and the operability of the operating body 16 is significantly improved. When using the normally closed type, remove the first biasing spring 70,
As shown in FIGS. 14 and 15, a second biasing spring 71 is provided between the common mounting portion 72 of the swing arm 17 and the second mounting portion 74.
Intervene.

In this normally closed type, the second biasing spring 71 is provided with an opening / closing plate.
When the operation body 16 is operated in the opening direction to open the extraction hole 21, the opening and closing plate is opposed to the second urging spring 71 as shown in FIG. 14 slides in the opening direction, and when the operating force of the operating body 16 is released, FIG.
As shown in FIG.
Slides in the closing direction. Therefore, the opening / closing plate 18 can open the extraction hole 21 only while the operation body 16 is operated in the opening direction.

Accordingly, it is possible to change a single ball game machine to either a toggle type or a normally closed type as required, and the first urging spring 70 and the second urging spring 71 can be changed. If two types are prepared, one type of upper plate unit can be used for both the toggle type and the normally closed type, so that the production cost can be reduced by mass production.

In the case of a normally closed type in the assembling stage, the locking portion 71b at one end of the second biasing spring 71 is moved to the swing arm.
After locking the locking portion 71c on the other end side to the second mounting portion 74 on the common mounting portion 72 of the 17 respectively, the support plate 25 may be fixed to the front plate 4 with screws or the like. Of course, it is also possible to change from a toggle type to a normally closed type or from a normally closed type to a toggle type according to the needs of a player in a game store or the like. In this case, since the front plate 4 is detachable from the front frame 1, first remove the front plate 4 from the front frame 1, and then remove the screws fixing the front plate 4 and the support plate 25. The front plate 4 is separated from the upper plate 6, the upper plate cover 7, and the like.

Then, since the rear side of the support plate 25 is opened, one of the first urging spring 70 and the second urging spring 71 is used, and one end of the urging springs 70, 71 is connected to the common mounting portion. 72
In addition, the other end side can be easily locked to the first mounting portion 73 or the second mounting portion 74, and it is sufficiently possible to change the wrapping spring used in a game shop or the like.

Structurally, the operating body 16 and the opening / closing plate 18 are linked via a swing arm 17, and the operating body 16 is operated to operate the opening / closing plate 18 via the swing arm 17. Therefore, by appropriately selecting the link ratio of the swing arms 17 on the upper and lower sides of the pivot 53, the movement amount of the opening / closing plate 18 can be made larger than the operation amount of the operating body 16, and the opening amount of the extraction hole 21 can be increased. The game ball in the upper plate 6 can be easily and smoothly and quickly extracted.

The operation body 16 operable in the left-right direction is arranged above the extraction hole 21, and the operation body 16 and the interlocking arm 36 are interlocked via the vertical swing arm 17. The operation body 16 can be easily arranged above the upper plate 6 and the operation amount of the operation body 16 in the left-right direction can be easily secured.
The overall size in the left-right direction can be reduced.

The opening / closing plate 18 has the upper plate 6
There is an interlocking arm 36 protruding on the opposite side to the opposite side, and a common mounting portion 72 for locking each of the urging springs 70, 71 is provided on the distal end side of the interlocking arm 36. 7
