  By the way, there are cases where it is necessary to remove the signal line from the connector on the functional component side due to manufacturing, maintenance or recycling. However, in the conventional game board, there is no space in the component mounting hole. Therefore, when the signal line is easily removed from the connector located in the component mounting hole, it is difficult to insert a fingertip or the like into the component mounting hole, and the workability cannot be said to be good.

  In addition, a functional part such as a gate having a game ball detection function has a detection switch having a connector portion, and the detection function is demonstrated by connecting the signal line to the connector portion from the rear side of the game board. It is supposed to be. In this case, if the detection switch is damaged and needs to be replaced, the detection switch itself needs to be removed in addition to the signal line. In general, the detection switch is disengaged from the signal line in the same direction as the signal line, so that the removal operation is performed from the rear side of the game board as in the case of the signal line. However, since the detection switch is also located in the component mounting hole, the removal operation cannot be easily performed.

  The present invention has been made in view of the above problems, and a first object thereof is a game board of a ball game machine capable of easily performing a work of removing a signal line from a functional component attached to the game board. Is to provide. A second object of the present invention is to provide a game board of a ball game machine that can easily perform the work of removing the game ball detection means from the game ball detection device that is a kind of the functional component.

In order to solve the above-mentioned problem, the invention described in claim 1 is a game ball detection device having a function of detecting the passage of a game ball, through which component mounting holes that open at the front surface and the rear surface of the game board are formed. Is attached to the component mounting hole, and a signal line for sending a game ball detection signal to the control device side disposed in the machine is detachably connected to the game ball detection device from the rear side of the game board, A game board of a ball game machine in which a connection portion between the game ball detection device and the signal line is disposed in the component attachment hole, and the game ball detection device attached to the component attachment hole includes: In order to detect a game ball passing through the passage, a detection device body in which a passage portion allowing passage of the game ball is located on the front side of the game board, a detection means holding portion is located in the component mounting hole, and It is held in the detection means holding part of the detection device body. A game ball detection means, and a detection means side connector portion detachably connected to a signal line side connector portion provided at a rear end of the game ball detection means and provided at a tip of the signal line, The component mounting hole has a substantially oval shape when viewed from the front, the major axis of the opening on the front side of the game board is larger than the diameter of the gaming ball, and the minor axis of the opening on the front side of the gaming board is larger than the diameter of the gaming ball. Formed so as to be small, and at the opening edge on the rear surface side of the game board of the component mounting hole, a recess having a size that allows the operator to insert a fingertip is formed over the entire periphery of the hole in a front view. The game ball detecting device is mounted and fixed in the component mounting hole by screwing a screw from the front side of the game board into which a game nail is driven. Is the gist.
In this case, the depth of the recess is set such that the tip of the game nail and the tip of the screw do not protrude, and the side wall surface of the recess is perpendicular to the front surface of the game board and the rear surface of the game board. The bottom surface of the recess is preferably parallel to the front surface of the game board and the rear surface of the game board (Claim 2). In addition, provided with a rear portion of the detection means holding portion of the detection device main body, the locking means is detachably locked to the game ball detection means, the locking means is a long diameter of the recess It is preferable that it is configured to be engaged and disengaged along the radial direction. In addition, the locking piece as the locking means has its tip disposed in the recess, while the detection means side connector portion is not disposed in the recess but in the component mounting hole. It is preferable that they are arranged (claim 4). The gaming ball detection device includes a decorative portion having a flange portion that comes into contact with the front surface of the game board, and a boss for preventing rattling is protrudingly provided on the back surface side of the flange portion. It is preferable that the boss is inserted into the component attachment hole and disposed in contact with the inner wall surface of the hole, and a space is provided between the inner wall surface of the hole and the detection means holding portion.

Therefore, according to the first aspect of the present invention, since there is a space in the vicinity of the connection site in the component mounting hole due to the formation of the recess, it is easy to insert a fingertip or the like into the component mounting hole. Therefore, by operating the connection part in the part attachment hole fingertip or the like, a signal line can be easily removed in a kind of game ball detection apparatus or al game board rear direction of the functional components. For the same reason, a signal line can be easily attached to a game ball detector that is a kind of functional component.

  Here, the “component mounting hole” is a through hole that opens at the front surface of the game board and the rear surface of the game board, and is mounted in a state in which a part of the functional component is inserted into the component mounting hole. The cross-sectional shape of the component mounting hole can be selected as appropriate according to the shape and type of the functional component to be mounted therein. For example, the cross-sectional shape is generally circular, the cross-sectional shape is generally oval, the cross-sectional shape is generally oval, and the cross-sectional shape is generally triangular. And a substantially rectangular shape in cross section.

In addition, it is preferable that the said component attachment hole is comprised so that a game ball cannot pass. That is, the component mounting hole is small enough to prevent the game ball from passing therethrough. Accordingly, or a recess in the component mounting hole, unless interest is larger than the opening area of the game board front side opening the opening area of the game board rear surface side opening portion of the part attachment hole, game balls can pass Compared with the case where the component mounting hole is configured to be, it becomes more difficult to insert a fingertip or the like into the component mounting hole. Therefore, the effect of forming the recess and the effect of making the opening area of the opening on the rear side of the game board larger than the opening area of the opening on the front side of the gaming board are components attached so that the game ball can pass. It becomes larger than the case where a hole is comprised.

  Examples of the functional components include a game ball detection device having a function of detecting the passage of game balls such as a gate, a start winning opening, a normal winning opening, and a big winning opening. In addition, a symbol display device for displaying a symbol variation game by variably displaying a plurality of types of symbols may be used. Further, various effect devices that contribute to the effect expression of the symbol variation game, specifically, side lamps attached to the left side portion or the right side portion on the front side of the game board, and the like.

  In addition, as a game related function of a functional component, when a functional component is a game ball detection apparatus, the function etc. which detect passage of a game ball are mentioned. In addition, when the functional component is a symbol display device, a function for displaying a symbol variation game is exemplified. Furthermore, when the functional component is a light emission effect device that performs a light emission effect or the like in accordance with the symbol variation game, for example, a side lamp, a function of lighting (flashing) the side lamp can be cited.

  Here, the connection part between the functional component and the signal line may be a connection part when the functional component and the signal line are directly connected, or may be a connection part when the functional component is connected indirectly. May be. The connection part in the case where the functional component and the signal line are directly connected means a part composed of the rear end portion of the functional component and the front end portion of the signal line. On the other hand, as a connection part when the functional component and the signal line are indirectly connected, for example, the functional component side connector portion provided at the rear end of the functional component and the signal line side connector provided at the front end of the signal line And a part composed of a part.

  The component mounting hole can be formed through by a conventionally known processing method, and it is preferable to employ, for example, rotational cutting (for example, cutting with a milling machine having an end mill). In the case of rotary cutting, the recess may be processed at the same time as the part mounting hole is processed. According to this method, the recess can be formed without changing the tool, so that the game can be efficiently performed without increasing man-hours. A board can be obtained.

  Further, the side wall surface of the recess is preferably perpendicular to the front surface of the game board and the rear surface of the game board, and the bottom surface of the recess is preferably parallel to the front surface of the game board and the rear surface of the game board. . Since the concave portion having such a shape can be easily formed by a processing method using a rotary cutting tool, the concave portion can be processed together with the processing of the component mounting hole.

  Moreover, the said recessed part may be formed in a part of opening edge of the said component attachment hole, and may be formed over the perimeter of the opening edge of the said component attachment hole. However, if the size of the component mounting hole is such that a fingertip cannot be inserted, the recess is preferably formed over the entire circumference of the opening edge of the component mounting hole. In this way, the direction in which the fingertip is inserted into the component attachment hole is not limited, and therefore the signal line attaching / detaching operation becomes easier.

  Further, since the game nail is driven into the front side of the game board and the functional component is fixed with a screw, the depth of the recess is set to such an extent that the tip of the game nail and the tip of the screw do not protrude. It is preferable. In other words, the thickness of the portion where the recess is formed in the game board may be set to be larger than the amount of game nails and screws buried in the game board. In this way, when a fingertip or the like is inserted into the component mounting hole, the finger or the like can be prevented from coming into contact with the tip of the game nail or the tip of the screw, and the operation can be performed with peace of mind. The depth of the recess (the distance from the rear surface of the game board to the bottom surface of the recess) is not particularly limited, but considering that the amount of game nails and screws buried is usually about 1/3 of the thickness of the game board It is preferable to set the thickness to about 1/4 to 1/2 of the thickness. That is, if the recess is too shallow, the fingertip cannot be sufficiently inserted. Conversely, if the recess is too deep, the tip of the game nail and the tip of the screw are likely to protrude. Moreover, if the amount of burying is reduced so as to avoid protrusion of the game nail or the screw, the fixing strength of the game nail or the screw is deteriorated.

  In addition, it is preferable that the opening area of the game board rear surface side opening part of the said component attachment hole is set to the magnitude | size which an operator can insert a fingertip at least. In this way, a space in which the fingertip can be inserted is secured in the opening on the rear side of the game board, so that the signal line can be attached and detached more easily. In addition, when the cross-sectional shape of the game board front side opening and the game board rear side opening of the component mounting hole is substantially circular, elliptical or oval, the maximum diameter of the game board rear side opening is the front of the game board. It is good that it is larger than the maximum diameter of the side opening.

By the way, according to the first aspect of the invention, the locking means can be easily released from the game ball detection means by hooking a fingertip or the like on the locking means in the component mounting hole. By operating the game ball detecting means, the game ball detecting means can be easily detached from the game ball detecting device in the direction of the rear surface of the game board. For the same reason, the game ball detection means can be easily attached to the game ball detection device.

  Here, the “connection portion between the game ball detection device and the signal line” refers to a connection portion when the game ball detection device and the signal line are indirectly connected. That is, the said connection part means the site | part which consists of the detection means side connector part provided in the rear end of the game ball detection apparatus, and the signal line side connector part provided in the front-end | tip of a signal line.

  As the locking means, a locking claw that is integrally formed at the rear part of the detection means holding part and detachably engages with the rear surface of the game ball detection means, or a rotating shaft part at the rear part of the detection means holding part. There is a locking piece that is provided via the hook and that is detachably locked to the game ball detection means, but is preferably a locking claw. This is because it is possible to suppress an increase in the number of parts constituting the game ball detection device.

  For example, the locking means engages / disengages in a direction (that is, a direction along the front surface of the game board and the rear surface of the game board) substantially perpendicular to the direction of attaching / detaching the signal line (that is, a direction perpendicular to the front surface of the game board and the rear surface of the game board) When comprised, it is preferable that the recess is formed so as to extend in the engagement / disengagement direction of the locking means. According to this configuration, a space that allows the locking means to be engaged and disengaged is secured in the vicinity of the locking means.

As described above in detail, according to the invention described in claim 1 to 5, is possible to perform the operation of removing the game ball detection apparatus or al signal line which is a kind of the game board to the attached functional unit product readily I can .

As a result, the speaker 21 outputs sound based on the sound control signal.

  Next, a procedure for removing the signal line 34 from the gate 31 attached to the game board 11 will be described. First, a fingertip is inserted into the recess 43 from the game board rear surface 11 b side of the game board 11. Next, the signal line side connector portion 34a is grasped with the fingertip and pulled in the direction of the rear surface 11b of the game board (the direction of the arrow F1 shown in FIG. 11). As a result, the signal line side connector portion 34a is pulled out from the detection switch side connector portion 33, and the signal line 34 is removed (see FIG. 11).

  Further, a procedure for removing the game ball detection switch 36 from the gate 31 from which the signal line 34 has been removed will be described. First, the fingertip is inserted again into the recess 43. Next, the fingertip is hooked on the locking piece 37 and the locking piece 37 is operated to elastically deform the locking piece 37 (see the broken line portion in FIG. 12). As a result, the locking of the locking piece 37 with respect to the game ball detection switch 36 is released. Further, in this state, the rear end portion of the game ball detection switch 36 is gripped and pulled in the direction of the game board rear surface 11b (the direction of the arrow F2 shown in FIG. 12). As a result, the game ball detection switch 36 is pulled out from the switch holder 39 and the game ball detection switch 36 is removed (see FIG. 12).

  Next, a procedure for attaching the game ball detection switch 36 to the gate 31 will be described. First, the rear end portion of the game ball detection switch 36 is grasped and inserted into the switch holder 39. At this time, the locking piece 37 is pressed against the side surface of the game ball detection switch 36 and elastically deforms (see the broken line portion in FIG. 12). Thereafter, when the game ball detection switch 36 is completely inserted into the switch holder 39, the locking piece 37 is restored to the state before the deformation, and locked to the rear end of the game ball detection switch 36 (see FIG. 6). . As a result, the game ball detection switch 36 is attached to the gate 31.

  Thereafter, if the signal line side connector portion 34a at the tip of the signal line 34 is grasped with a fingertip and inserted into the detection switch side connector portion 33, the signal line 34 is connected to the gate 31 to which the game ball detection switch 36 is attached. It is attached.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) In the gaming board 11 of the present embodiment, since the formation of the recess 43 creates a space in the vicinity of the detection switch side connector portion 33 and the locking piece 37 in the component mounting hole 42, It will be easier to insert your fingertips. Therefore, by grasping and pulling the signal line side connector part 34a connected to the detection switch side connector part 33 with a fingertip, the signal line 34 is directed from the gate 31 to the rear surface 11b of the game board (the direction of the arrow F1 shown in FIG. 11). Can be easily removed.

  Further, when the signal line 34 is connected to the game ball detection switch 36, it becomes easy to grasp the signal line side connector portion 34 a with the fingertip and insert it into the detection switch side connector portion 33. Therefore, since the signal line 34 can be easily and reliably attached to the gate 31, the game ball detection switch 36 can be normally operated, and the passage of the game ball A1 can be reliably detected. Therefore, malfunction of the game ball detection switch 36 due to poor connection of the signal line 34 can be prevented.

  (2) In the present embodiment, the formation of the recess 43 makes it easy to insert a fingertip or the like into the component mounting hole 42. Therefore, by operating the locking piece 37 by hooking the fingertip on the locking piece 37. The locking of the locking piece 37 with respect to the game ball detection switch 36 can be easily released. Furthermore, by holding and pulling the game ball detection switch 36 with a fingertip in this state, the game ball detection switch 36 can be easily removed from the gate 31 in the direction of the rear surface 11b of the game board (the direction of arrow F2 shown in FIG. 12). it can.

  Also, when the game ball detection switch 36 is attached to the gate 31, it becomes easy to hold the game ball detection switch 36 with a fingertip and insert it into the switch holder 39. Therefore, since the game ball detection switch 36 can be reliably held by the switch holder 39, the positional relationship between the game ball passage hole 47 and the passage portion 38 can be appropriately maintained. Therefore, since the possibility that the game ball A1 passing through the game ball passage hole 47 (passage portion 38) is caught is reduced, the game ball detection switch 36 can reliably detect the passage of the game ball A1.

  (3) In the present embodiment, the side wall surface 43a of the recess 43 is perpendicular to the game board front surface 11a and the game board rear surface 11b. For this reason, the concave portion 43 can be formed without tilting the rotary cutting tool when performing the rotary cutting process. Therefore, compared with the case where the side wall surface 43a of the recessed part 43 is inclined with respect to the game board front surface 11a and the game board rear surface 11b, formation of the recessed part 43 becomes easy. Further, the bottom surface 43b of the recess 43 is parallel to the game board front surface 11a and the game board rear surface 11b. For this reason, compared with the case where the bottom surface 43 b of the recess 43 has an undulating shape, the fingertips inserted into the component mounting holes 42 are less likely to contact the bottom surface 43 b of the recess 43.

  (4) By the way, on the game board rear surface 11b side of the game board 11, a large number of boards, electrical components, and the like are provided densely, so it is difficult to secure a space for forming the recess 43. Therefore, in the present embodiment, the recess 43 is formed to have a substantially oval shape when viewed from the front. Thereby, the opening area of the recessed part 43 can be suppressed to the minimum. In addition, it is possible to secure at least a space where the connection part B1 is arranged and a space where a fingertip or the like can be inserted. Specifically, it is possible to secure a space in which the connection site B1 is arranged at a substantially central portion in the recess 43, and to secure a space where a fingertip or the like can be inserted on each side of the connection site B1.

  In addition, you may change embodiment of this invention as follows.

  -In the said embodiment, the opening area of the recessed part 43 was set to the magnitude | size which an operator can insert a fingertip. However, the opening area of the recess 43 may be further increased. In this way, since the space secured in the recess 43 becomes wider, the attaching / detaching work of the signal line 34 and the game ball detection switch 36 becomes even easier.

  In the above embodiment, the recess 43 may be deeper. In this way, the connection portion B1 is easily exposed in the recess 43, and thus the signal line side connector portion 34a and the game ball detection switch 36 are more easily gripped.

  In the above embodiment, the recess 43 is formed in the component mounting hole 42 to which the gate 31 is mounted. However, the present invention is not limited to this, and the recess 43 is formed in the component mounting hole to which other than the gate 31 is mounted. You may make it form. For example, a component mounting hole 61 to which the lighting device 18 and the normal winning ports 23a and 23b are mounted, a component mounting hole 62 to which the starting winning port 14 and the like are mounted, and a center accessory 22 provided with the liquid crystal symbol display device 15 are mounted. The recessed portion 43 may be formed in the component mounting hole 63 or the like (see FIG. 2).

  In these cases, the recess 43 may not be formed over the entire circumference of the component mounting hole but may be formed only in a part of the component mounting hole. In particular, when the opening area of the component mounting hole is large, such as a component mounting hole to which the center accessory 22 is mounted, it becomes difficult to insert a fingertip or the like even if the recess 43 is formed in a part of the component mounting hole. Such an adverse effect is less likely to occur.
