Japanese Patent No. 5769917 JP 2010-22591 A JP 2013-85804 A

By the way, in general, pachinko machines are generally limited in width and depth to a certain level or less, and as described above, a sufficient space can be secured for providing a large effect device on the game board. In addition, there is a problem that it is not possible to provide an effect device that is large and has a depth.
In addition, in the gaming machine shown in Patent Document 1, the gaming board can be enlarged by arranging the locking devices in an inclined shape in plan view. However, it is required to provide a larger-sized production device on the game board so as to enhance entertainment.

Further, as described above, the conventional ball game machine pivotally supports the main body frame and the front frame on the machine frame, and the main body frame includes not only a game board but also a ball launching device and a ball dispensing device. In addition, heavy equipment such as a power supply device is provided, so if the front frame and the main body frame are opened forward, the center of gravity will move large and the weight balance will deteriorate, making it easy for the entire gaming machine to fall forward. It is difficult and the machine frame is always heavily loaded via the shaft support, so it is necessary to construct the machine frame and the shaft support robustly, which increases the manufacturing cost and increases the strength. In order to ensure, it is necessary to make the material constituting the machine frame thick and wide, there is a problem that the space in which component parts such as a large-sized production device can be provided has to be narrowed.
Further, in conventional ball game machines, a ball payout control board that counts and controls the number of game balls to be paid out to the player each time a game ball wins, and a variable prize opening provided on the game board is opened and closed. When inspecting whether the main control board that is being controlled has been modified such as replacing the ROM for illegal purposes, the state of these control boards must be changed unless the main body frame that cannot be opened and closed is opened. Since I could not see it, there is a problem that it takes time and effort to perform such an inspection.

The ball game machine according to the present invention is intended to solve the above-described problem, and forms a vertically long rectangular housing having a front surface opened and a depth in the front-rear direction so that it can be fixed to an island base of a game arcade.

If it is overhanging, it will collide with the opening edge of the chassis, so in order to avoid the collision, the back side that is diagonal to the rotation base point of the game board cannot be overhanged There is a problem, and for this reason, there is a problem that the inner back part of the other side edge of the chassis that is diagonal to the rotation base point of the game board becomes a dead space. On the other hand, in the present invention, the space can be effectively utilized by disposing a ball dispensing device that extends downward from the dispensing ball tank through the ball supply basket in this dead space. For this reason, the member provided in this space does not interfere with the mounting (storing) while rotating the game board. A large effect device can be provided on the back side of the game board as long as it does not collide with the opening edge of the chassis during rotation.
According to the present invention, in the above-described ball game machine, a transparent sealing case containing a ball payout control board is fixed to an inner lower front surface of the housing, and a front frame holding a transparent plate is attached to the front surface of the game board. The ball payout control board is supported on one side edge of the housing so as to be openable and closable, and the front frame is opened so that the ball payout control board is visible from the front.
For this reason, the presence or absence of unauthorized modification of the ball payout control board can be easily inspected simply by opening the front frame.
Further, the present invention provides a main control board that controls the opening and closing movement of a variable winning opening provided in the game board by fixing a transparent sealing case so as to be positioned below the lower edge of the game board.

A long hole 93a to 93c is formed, and an operating rod 95 which is mounted on one side of the vertically long plate 90 so as to be vertically movable by inserting pins 94a to 94c into the long holes 93a to 93c, and tension springs 96a and 96b. I have. The engaging members 80a and 80b are formed in a cam shape at the outer peripheral edge, the engaging groove 80c and the locking groove 80d are formed substantially in parallel, and a spring hooking portion 80e is formed on the back portion thereof. Then, the other ends of the tension springs 96a and 96b having one end hooked to the spring hooking portion 95d of the operating rod 95 are hooked to the spring hooking portion 80e of the engaging members 80a and 80b. Further, the tip of the rotating piece 91 is engaged with an engagement hole 95 c formed in the lower part of the operating rod 95. Further, latch pins 95a and 95b that can be engaged with and disengaged from the locking grooves 80d of the engaging members 80a and 80b are provided on the side surfaces of the operating rod 95.

  Therefore, when a key is inserted into the cylinder lock 79 and the rotary piece 91 is rotated clockwise to move the operating rod 95 upward, the latch pins 95a and 95b are pulled out of the lock groove 80d and the engaging members 80a and 80b are pulled. The engagement grooves 80c are rotated by the elasticity of the springs 96a and 96b so that the engagement grooves 80c face the engagement pieces 63a and 63b. At this time, if the hand is released with the key inserted into the cylinder lock 79, the latch pins 95a and 95b are brought into contact with the cam-shaped outer peripheral edges of the engaging members 80a and 80b by the elasticity of the tension springs 96a and 96b. Therefore, the rotating state of the engaging members 80a and 80b is maintained. That is, the engaging groove 80c is latched in a state facing the engaging pieces 63a and 63b. At this time, the operating rod 95 is maintained in the upward movement state by the pins 95a and 95b coming into contact with the outer peripheral edges of the engaging members 80a and 80b. When the front frame 70 is closed in this latched state, the engaging pieces 63a and 63b enter the engaging grooves 80c of the engaging members 80a and 80b and rotate the engaging members 80a and 80b upward, as shown in FIG. As described above, the engagement pieces 63a and 63b are engaged with the respective engagement grooves 80c, the latch pins 95a and 95b are engaged with the lock grooves 80d of the engagement members 80a and 80b, and the operating rod 95 is moved downward. Therefore, the front frame 70 is locked in the closed state by returning the key to the original rotation state and removing the key from the cylinder lock 79.

  An upward protrusion 86 is fixed to the upper portion of the vertically long plate 90 via a fixing member 86 a, and the upward protrusion 86 protrudes from the back surface of the front frame 70 so as to face the guide member 64. For this reason, when the front frame 70 is closed, the upward projection 86 rides on the guide member 64 so that the heavy front frame 70 is easily closed by the housing 40. Note that an elastic protrusion 87 projects from the upper edge of the back side of the front frame 70 so as to come into contact with the front surface of the game board 2 when the front frame 70 is closed.

  Further, by inserting a key into the cylinder lock 79 of the front frame 70 locked in the closed state and rotating the rotary piece 91 to move the operating rod 95 upward against the elasticity of the tension springs 96a, 96b, the latch pins 95a, Since 95b is removed from the locking groove 80d, the engaging members 80a and 80b are rotatable. In this state, the front frame 70 is pulled forward, so that the engaging pieces 63a and 63b are removed from the engaging groove 80c and the front frame is removed. 70 can be opened, and when the front frame 70 is in the open state, the latch pins 95a and 95b abut against the outer peripheral edges of the engaging members 80a and 80b as described above, so that the operating rod 95 is prevented from moving downward. It is maintained and latched in the upward movement state. In short, the open state of the locking device 78 is maintained even if the hand is released from the key. An interlocking tab 95e described below is bent at the lower end of the operating rod 95, and an engagement hole 95f is formed in the tab 95e.

  Next, the configuration of the entrance shutter device 100 shown in the exploded perspective view of FIG. 15 will be described. The entrance shutter device 100 is provided at the sphere entrances 84a and 84b of the front frame 70. The shutter member 100a is provided in the box-like body 101 having the sphere entrances 84a and 84b formed on the upper part thereof so as to be movable up and down. At the same time, the base end portion 102a of the transmission rod 102 is rotatably supported in the box-like body 101, and the tip of the pin 102b protruding from the substantially middle portion of the transmission rod 102 is engaged with the shutter member 100a. At the same time, the short shaft portion 102c formed at the other end of the transmission rod 102 is loosely fitted into the engagement hole 95f of the tab 95e. Reference numerals 103 and 104 denote lid bodies that are screwed to the box-shaped body 101. Further, the interlocking pin 100b is fixed to the shutter member 100a, the interlocking pin 100b is protruded from the notch 104a formed in the lid body 104, and when the front frame 70 is closed, the tip of the interlocking pin 100b is The engagement hole 68 is inserted. For this reason, when the operating rod 95 moves downward, the transmission rod 102 moves downward with the base end portion 102a as a fulcrum, and the pin 102b provided on the transmission rod 102 moves downward to move the shutter member 100a downward. For this reason, the ball inlets 84a and 84b are opened. When the front frame 70 is closed, the ball inlets 84a and 84b are aligned with the ball outlets 59a and 59b, and the shutter member 100a and the shutter member 66a are connected via the interlocking pin 100b. 100a moves downward to open the ball inlets 84a and 84b, and at the same time, the shutter member 66a moves downward to open the ball outlets 59a and 59b. Therefore, the game balls paid out from the ball payout device 55 flow from the ball outlets 59a and 59b to the ball inlets 84a and 84b, and are paid out to the upper ball receiving tray 74 or the lower ball receiving tray 75.

On the other hand, when the operating rod 95 and the shutter member 100a are moved upward by opening the locking device 78, the ball inlets 84a and 84b are closed. At the same time, the interlocking pin 100b is moved up and the shutter member 66a is moved up, so that the ball outlets 59a and 59b are closed. When the front frame 70 is opened, the interlocking pin 100b is detached from the engagement hole 68, but the shutter member 66a is maintained in the upward movement state by the elasticity of the spring 67. For this reason, when the front frame 70 is opened, the game balls do not spill out from the ball outlets 59a and 59b and the ball inlets 84a and 84b.
When the front frame 70 is closed, the engaging pieces 63a and 63b move the operating rod 95 downward via the engaging members 80a and 80b, and the shutter member 66a and the shutter member 100a move downward. , 59b and the ball inlets 84a, 84b are opened, and the game ball is paid out.

  The locking device 78 only needs to have a function of holding the front frame 70 in a closed state with respect to the housing 40, so that the key is rotated clockwise as in a conventional locking device of a ball game machine. There is no need for complicated key operations such as opening only the front frame or simultaneously opening the main body frame depending on whether it rotates or rotates counterclockwise. For this reason, the structure of a locking device is simplified and cost is also reduced. Since only the front frame 70 can be easily opened and closed by a key operation, it is possible to deal with a clogged ball in the game area on the front surface of the game board 2 during the game. Also, inspection and inspection of the main control board 23 and the ball payout control board 56 are facilitated. Furthermore, by operating the clamping devices 46a and 46b with the front frame 70 in the open state, the gaming board 2 can be easily replaced from the front of the gaming machine.

As described above, in the ball game machine according to the present invention, the payout ball tank 58 is provided in the inner part of the upper edge 40a of the housing 40, and the ball payout that continues downward from the payout ball tank via the ball supply rod 57a. Since the device 55 is fixed at the inner back of the other side edge of the housing 40 that is diagonal to the rotation base point of the game board 2, the dead space of the housing 40 is effectively used. For this reason, a large and deep production device 13 can be provided on the game board 2.
In addition, the present invention replaces the machine frame and main body frame of the conventional ball game machine with a case 40 fixed to an island base of the game hall, and the game board 2 is detachably attached to the case 40. Therefore, it is not necessary to pivotally support a heavy body frame so as to be rotatable by a robust shaft support portion as in the prior art. For this reason, the cost can be reduced, the space can be afforded, and the large effect device 13 can be provided to make the game more interesting and powerful and enhance the amusement of the ball game machine.
In addition, the state of important control boards such as the main control board 23 and the ball payout control board 56 in the sealing cases 21 and 53, which are strongly related to the advantages and disadvantages of the game, can be changed even if the main body frame is not opened as in the prior art. Since it can be seen simply by opening 70, it can be easily inspected for the presence or absence of unauthorized modification without requiring labor.

In this embodiment, bearing pieces 15a and 15b are provided on one side edge of the game board 2 so as to pivotally support the one side edge of the game board 2. However, in the present invention, the game board 2 is not necessarily in such a manner. It is not necessary to have a pivotal support structure. By rotating the game board 2 in the horizontal plane with the inner side of one side edge of the case 40 as the base point of the game board 2, the game board 2 is mounted in the case 40. You just need to be able to wear it.
In this embodiment, the hitting ball launching operation handle 76 is provided on the front frame 70, but the gaming ball launching operation handle may be projected from the lower front portion of the housing 40. In this embodiment, the locking device 78 and the cylinder lock 79 are provided on the front frame 70, but the locking device 78 and the cylinder lock 79 may be fixed to one side edge of the front surface of the housing 40. Further, the hitting ball supply device 72, the relay board case 73, the upper ball receiving tray 74, the lower ball receiving tray 75, etc. are not required to be replaced at the same time when the game board unit 1 is replaced. It may be formed.
Thus, since the front frame 70 can be lightened by reducing the number of parts provided in the front frame 70, the weight burden on the multi-axis hinges 77a and 77b that are the shaft support portions can be further reduced. At the same time, the weight balance when the front frame 70 is opened can be improved.
In addition, the shape of the housing 40 does not necessarily have to be formed in a box shape with the back surface closed as shown in this embodiment. However, the formation of the box shape increases the strength and is relatively thin. Even if it is molded with a steel plate, it can be made robustly, so it is easier to secure a space that can accommodate a large production device etc., and a strong structure that can be pivotally supported even with a heavy front frame can be easily obtained .
