  In the inspection of game nails in a ball game machine, there is room for improvement from the viewpoint of facilitating the inspection.

The present invention according to claim 1, which has been made in view of the problem, is a spacer that is detachably provided on a ball game machine, and has a substantially cylindrical body and a circular shape having a larger diameter than the body. A plurality of game nails having a head are planted on a game board, and are used in a ball game machine that pays out a prize ball when a game ball wins a prize opening formed in the game board, A contact portion that is in contact with a part of the winning opening, and a location where at least two of the plurality of game nails should be positioned when a part of the winning opening is brought into contact with the corresponding contact portion A game nail insertion portion through which a game nail can be inserted is provided .

Furthermore, in the present invention described in claim 1 , the game nail insertion portion includes a head insertion portion which is a through hole through which the head passes, and the trunk portion of the game nail passing through the head insertion portion. A slit-shaped through-hole that can be positioned, and a width of the first body portion insertion portion that is substantially equal to the diameter of the body portion, and when the contact portion is in contact with a part of the winning opening A first head position indicating section that indicates a normal position of the head of the game nail inserted through the first body insertion section, and the contact section is brought into contact with a part of the winning opening The body portion of the game nail in a normal position is located in the first body portion insertion portion .

The present invention according to claim 2 is a spacer provided detachably on the ball game machine, and has a plurality of substantially cylindrical body parts and a circular head part having a larger diameter than the body part. A game nail is planted on a game board, and when a game ball is awarded to a prize opening formed on the game board, the game nail is used for a ball game machine that pays out a prize ball, and a part of the prize opening The game nail can be inserted into a position where at least one of the plurality of game nails is to be located when a part of the winning opening is brought into contact with the corresponding contact part. A game nail insertion portion, wherein the game nail insertion portion positions the head insertion portion which is a through hole through which the head passes and the trunk portion of the game nail passing through the head insertion portion. A first body part insertion portion having a width substantially equal to the diameter of the body portion, and the abutting portion of the winning opening When brought into contact with the parts, the first barrel portion insertion portion, the body portion of the game nail in the normal position, characterized in that position.
Here, in the first claim, the first head position indicating section “represents the normal position of the head of the game nail” is not limited to the meaning that the correct position of the head in the three-dimensional coordinates can be specified. Absent. For example, the first head position indicating unit may indicate only one component of the coordinates, or may be an arrow or a mark indicating the normal position.

Further, the spacer is larger when the abutting portion is larger than a portion of the winning opening abutted against the corresponding abutting portion, and the abutting portion is inserted when the gaming nail in a regular position is inserted into the gaming nail insertion portion. There may be so that with the contact position indicator unit indicating a position, to be contact with the winning openings.
Examples of the contact position indicating part include a mark printed on the contact part of the spacer, a sticker attached to the corresponding contact part, a relief-like mark formed on the corresponding contact part, a hole formed on the corresponding contact part, etc. Can be illustrated.
By the way, when the cross section of the winning opening is substantially U-shaped or substantially saddle-shaped, the contact portion can be configured as a straight edge. It is assumed that one game nail insertion portion is formed in the spacer in order to ensure that one game nail is in a normal position. As a result of mounting the spacer, when the game nail is inserted into the game nail insertion portion and the abutment portion is in close contact with the upper end of the winning opening, the distance between the gaming nail and the winning opening (more precisely, the winning The distance from the straight line connecting the two upper ends of the mouth is correct. However, this spacer cannot guarantee that the game nail is not slightly displaced in the direction parallel to the straight line connecting the upper ends. A similar problem may occur in a spacer having a plurality of game nail insertion portions and a ball game machine in which the upper ends of the winning holes are not aligned. Therefore, according to the configuration of the spacer as described above, the contact portion of the spacer is configured to be larger than the portion of the winning opening that is in contact with the corresponding contact portion, and the game nail in the regular position is replaced with the game nail. An abutting position indicating unit is provided that represents a position where the abutting portion should abut the winning opening when inserted through the insertion portion. According to the spacer, when the deviation occurs, the contact position indicating unit indicates a position shifted from the position where the winning position should be contacted, so that it is possible to ensure that there is no deviation.

The spacer is used for a ball game machine whose cross section parallel to the game board of the winning opening is substantially U-shaped or substantially bowl-shaped, and at least one recess is formed at the lower end of the spacer. It is, may be as a said abutment depressions Mino bottom comes into contact with the upper end of the winning openings.
According to such a spacer configuration, the cross section of the winning opening is substantially U-shaped or substantially bowl-shaped, and at least one depression is formed at the lower end of the spacer, and the bottom of the depression is the winning opening. It is the contact part which contacts each upper end of. This is a configuration in which the depression acts close to the spacer contact position indicating portion described above. Therefore, when the shift occurs, the position of the upper end of the winning opening is shifted in the recess, so that the generated shift is easy to find. It is to be noted that when there are two depressions, the width of each depression is the same as the width of the two upper ends of the winning opening (exactly slightly larger), and each depression enters the corresponding upper end, When a deviation occurs, the spacer cannot be brought into contact with the winning opening, and there is a high possibility that the game nail itself cannot be inserted into the game nail insertion portion. In this aspect, it is possible to guarantee that the above-mentioned deviation is not caused by the fact that the spacer is mounted on the ball game machine.

  Here, “the cross-section is substantially U-shaped or substantially saddle-shaped” means that there are walls on both the left and right sides of the place where the game ball enters and the height of the upper end of the wall is the same. Pointing. Accordingly, a winning opening provided with members for the purpose of ensuring design and strength on the left and right outer sides of these walls, the lower part of the bottom, or the near side is also included. In addition, by providing a rib in the entrance that does not hinder the entry, a winning opening having a bowl shape in the cross section is included depending on the position.

The present invention according to claim 3 is a spacer provided detachably on the ball game machine, and has a plurality of substantially cylindrical body parts and a circular head part having a larger diameter than the body part. A game nail is planted on a game board, and when a game ball is awarded to a prize opening formed on the game board, the game nail is used for a ball game machine that pays out a prize ball, and a part of the prize opening A second body part insertion part that is a slit having a width substantially equal to the diameter of the body part of the nail, and the contact part is formed in one of the winning holes. And a second head position indicating section representing a normal position of the head of the game nail inserted through the second trunk section insertion section when brought into contact with the section .
Here, the second head position instruction section itself may be the same as the first head position instruction section (the same applies to a third head position instruction section described later).
The spacer according to claim 3 is different from the spacer according to claims 1 and 2 in that the head insertion part is not a constituent element, and the second trunk insertion part is configured instead of the first trunk insertion part. It differs in the requirements. Note that, as described above, the first head position indicating unit and the second head position indicating unit are substantially the same except that the related trunk insertion units are different. The difference between the first body portion insertion portion and the second body portion insertion portion is that the former is a through hole formed in the spacer, whereas the latter is a notch formed from the contact portion (in the claims, “ It is expressed as “slit”. Therefore, in order to position the body portion of the game nail in the body insertion portion, it is necessary to first move the game nail after inserting the game nail into the head insertion portion, The second body insertion portion can move the body directly from the contact portion. For this reason, the spacer according to claim 1 has two game nail insertion portions, and the two game nails inserted into each game nail insertion portion have a C-shaped posture. In contrast, the spacer according to claim 3 is configured such that the entrance of the second body portion insertion portion formed in the abutting portion is positioned at the position of the game nail (in the above example, the C shape). It is possible to attach a spacer by adjusting to the details described later, and it can be ensured that the game nail is in a normal posture.

In addition, the spacer is larger when the contact portion is larger than a portion of the winning opening that is in contact with the corresponding contact portion, and when the game nail in a normal position is inserted into the second body insertion portion, the contact portion part position should contact the winning openings, it may be so that with the contact position indicator unit indicating a.
According to such a spacer configuration, when a deviation occurs, the contact position indicating unit indicates a position different from the position where the winning opening should be contacted. it can.

The present invention according to claim 4 is a spacer detachably provided in a ball game machine, and has a plurality of substantially cylindrical body parts and a circular head part having a larger diameter than the body part. The game nail is planted on a game board, and is used for a ball game machine that pays out a prize ball when a game ball wins a winning opening formed on the game board. The same number of the games in the normal position in the back of the third trunk part insertion part and the plurality of third trunk part insertion parts, both of which are substantially equal in width to the diameter of the trunk part of the nail. And a winning opening position indicating section that indicates the position of the winning opening when the body portions of the nails are brought into contact with each other .
The spacer according to claim 4 is different from the spacer according to claim 3 in that the second head position indicating portion is not a constituent feature, and the third trunk portion insertion portion is replaced with the second trunk portion insertion portion. The difference is that the configuration requirement is different from the configuration in which a winning opening position indicating unit is used instead of the contact portion.
The difference between the second body part insertion part and the third body part insertion part is that first, at least one of the former needs to be present, whereas a plurality of the latter need to exist. Secondly, the former has a normal position of the trunk in one of the slit-shaped second trunk insertion parts, whereas the latter has the normal position of the trunk in the innermost part of the third trunk insertion part. It is a point limited to. Thus, in the gaming machine according to the fourth aspect, since the normal position of the trunk is relatively easy to understand, the second head position indicating unit is not a constituent requirement. The difference between the abutting portion and the winning opening position indicating portion is that the former needs to be in contact with at least a part of the winning opening, whereas the latter need not be in contact with the winning opening depending on the mode (of course. May contact).
According to the spacer according to claim 4 configured as described above, when the trunk portion is positioned at the innermost part of the third trunk portion insertion portion, the winning opening position indicating portion correctly represents the position of the winning opening. Whether or not the game nail is in the correct position can be assured.

According to the spacer of the first aspect, since the game nail insertion portion is formed at a position where the game nail should be positioned when the contact portion is brought into contact with the winning opening, the gaming nail is correct with respect to the winning opening. Whether or not it is in the position can be easily determined by looking at the mounted spacer. The winning opening is a relatively robust structure fixed to the game board, whereas the game nail may be bent or tilted as a whole. Therefore, if the game nail is not in the correct position with respect to the winning opening, the cause is mostly the game nail. And since the contact part of a spacer is contact | abutted to a winning opening, and a game nail is inserted in a game nail insertion part, it can be determined whether the game nail is in the correct position, without seeing a spacer from the front. Thereby, it is possible to guarantee to the delivery destination that the game nail of the ball game machine is in the correct position. During the game, it is only necessary to release the game nail from the game nail insertion portion and remove the spacer of the present invention, which does not hinder the game. As described above with respect to the “ regular position”, the “location to be positioned” of the game nail is not limited to the meaning of the correct position of the game nail in the three-dimensional coordinates. That is, it may be only one component of the coordinates may be the distance from Jo Tokoro linear up game nails.

Moreover, according to the spacer of Claim 1 , the said spacer can be moved along the 1st trunk | drum insertion part, with the trunk | drum of a game nail inserted in the 1st trunk | drum insertion part. Thereby, desorption of a spacer can be performed easily. In order to show a specific example of this, for a ball game machine in which a decorative board (described later) larger than the winning opening is provided in front of the winning opening (front side as viewed from the player), Consider a case in which a spacer having a game nail insertion portion, which is a circular through hole with no distinction between one trunk portion insertion portion, is attached. In this case, the spacers are pushed in from the front by aligning the positions of the game nail insertion part and the game nail in the direction parallel to the game board, but depending on the shape of the decorative board, the decorative board may become an obstacle to the pushing. There is sex. In this regard, according to the spacer according to claim 1, by forming the head insertion portion in a position where it does not interfere with spacer escutcheon, by aligning the head insertion portion and gaming nails, spacer from the front The spacer may be moved to the normal position along the first body insertion portion. In other words, in the state where the contact portion is in contact with the winning opening, even if there is a positional shift along the first trunk insertion portion in the game nail, there is a possibility that the spacer can be mounted. When the positional deviation exists, the head of the game nail is not located at the position indicated by the first head position indicating unit, so that the existence of the positional deviation can be easily known.

  FIG. 5 shows a state where the spacer 11 is mounted on the first start port 47. FIG. 5A is an enlarged view of the spacer 11 and the first start port 47 as viewed from the front. FIG. 5B is a right side view of the spacer 11 and the first start port 47. Note that the game board 40 is partially cross-sectional. As is well shown in the figure, the spacer 11 is a plate-like member, and is installed at the upper portion near the tip of the first starting port 47 (front side as viewed from the player). A decorative plate 12 for design purposes is attached to the tip of the first start port 47. FIG. 5C shows a state in which the decoration plate 12 is removed from the first start opening 47 and viewed from the front. As shown in the figure, the first starting port 47 has a U-shaped cross section, and the lower end 11a of the spacer 11 is in contact with the upper end 47a. The spacer 11 is formed with two through holes 13 through which the head 43h of the game nail 43S passes. The spacer 11 may be made of metal or plastic, but it is desirable that the spacer 11 has a strength that does not easily bend. In the case of plastic, acrylic resin, polycarbonate, vinyl chloride and the like can be exemplified.

  The game nail 43S is planted substantially perpendicular to the game board 40, and has a circular head 43h as viewed from the player, a trunk 43b having a smaller diameter than the head 43h, and a tapered shape. When used, the game board 40 is pierced and has a tip part 43t embedded in the game board 40 together with a part of the body part 43b.

  FIG. 6A shows a state where only the spacer 11 is taken out. As shown in this figure, the through-hole 13 includes a circular head insertion portion 14 and a trunk portion insertion portion 15 having a smaller diameter than the head insertion portion 14. The diameter of the head insertion portion 14 is slightly larger than the diameter of the head 43h of the game nail 43S, and the diameter of the trunk portion insertion portion 15 is slightly larger than the diameter of the trunk portion 43b of the game nail 43S. Reference numeral 17 denotes a knob that is gripped when the spacer 11 is attached to or detached from the pachinko machine 10. The trunk portion insertion portion 15 can be regarded as a part of a slit-shaped hole as indicated by a broken line 15a. The width d of the slit-shaped hole (see FIG. 6B) is configured to be slightly larger than the diameter of the trunk portion 43b of the game nail 43S. The distance w between the centers in the width direction (X-axis direction) of the two trunk portion insertion portions 15 corresponds to the distance between the two game nails 43S at the normal position. The distance between the two game nails 43 </ b> S (more precisely, the distance between the two trunks) is the size of the entrance of the first start port 47.

  When the lower end 11 a comes into contact with the upper end of the first start port 47, if the game nail 43 </ b> S is in the normal position, the trunk portion 43 b is located in the trunk portion insertion portion 15. A distance L from the center of the trunk portion 43b to the lower end 11a corresponds to a distance from the game nail 43S in the normal position to the upper end 47a of the first start port 47 (not shown). When the lower end 11a comes into contact with the upper end of the first start port 47, the head position indicating unit 16 indicates a position where the head 43h of the game nail 43S is located when viewed from the front. The head position indicating unit 16 is an arc-like broken line printed on the surface of the spacer 11, and the diameter thereof is substantially the same as the head 43h of the game nail 43S.

  In order to attach the spacer 11 to the pachinko machine 10, the two head insertion portions 14 and the heads of the two game nails 43S are aligned with each other when viewed from the front, and the spacer 11 is in the back direction (parallel to the Z axis). The two game nails 43 are inserted through the two head insertion portions 14, respectively. At this time, if the decorative plate 12 is in the way, the lower end 11a of the spacer 11 may be first positioned behind the decorative plate 12. When the two game nails 43 are inserted through the two head insertion portions 14, the entire spacer 11 is shifted downward, and the body portions 43 b of the two game nails 43 are positioned at the two body insertion portions 15. . At this time, if both of the two game nails 43 are in the normal position, the lower end 11 a of the spacer 11 comes into contact with the upper end 47 a of the first start port 47. When viewed from the front, the head position indicating unit 16 overlaps with the head 43h of the game nail 43S and is hardly visible (FIG. 5A).

  On the other hand, when the two game nails 43S are at a position slightly lower than the normal position, when the spacer 11 is attached and viewed from the front, the head position indicator 16 protrudes from above the head 43h of the game nail 43S. (FIG. 6C). When the two game nails 43S are at a position slightly higher than the normal position, the entire spacer 11 is lifted by the two game nails 43S, and the lower end 11a of the spacer 11 is connected to the first start port 47. It cannot be brought into contact with the upper end 47a (FIG. 6D). In addition, in FIG.6 (c) and FIG.6 (d), the decoration board 12 is removed for convenience of illustration.

  When only one of the two game nails 43S is higher (or lower) than the normal position, the body 43b of the two game nails 43S cannot be positioned in the body insertion part 15, It is considered that the state is close to 6 (c). When the positional deviation between the two game nails 43 </ b> S is large, the head 43 h cannot be inserted into the head insertion part 14, and there is a high possibility that the spacer 11 cannot be attached to the pachinko machine 10. In addition, even when the interval between the two game nails 43S is too wide (or too narrow), the body 43b cannot be positioned on the body insertion part 15, and is considered to be in a state close to FIG. It is done.

  The pachinko machine 10 to which such a spacer 11 cannot be attached can determine that the game nail 43S is not in the normal position. The pachinko machine 10 in which the spacer 11 is mounted on the upper part of the first starting port 47 is configured so that the lower end 11a of the spacer 11 is in contact with the upper end 47a of the first starting port 47 and whether it is viewed from the front. Whether or not the game nail 43S is in the normal position can be determined by checking whether or not the position of the head 43h of 43S is shifted from the head position instruction unit 16. In addition, when manufacturing the pachinko machine 10, it is possible not only to confirm that the position and posture of the game nail are appropriate, but also to ensure that the position and posture of the game nail 43S of the pachinko machine 10 delivered through transportation is appropriate. Can also be confirmed. In addition, the two game nails 43S define the size of the entrance of the first start port 47 by the inner distance of each body portion 43b. It can be easily confirmed that it is appropriate.

  Here, the correspondence between the configuration of the present embodiment and the configuration requirements of the present invention is shown. The through hole 13 corresponds to the “game nail insertion portion” of the present invention, the lower end 11a of the spacer 11 corresponds to the “contact portion” of the present invention, and the first start port 47 corresponds to the “winning port” of the present invention. And the trunk | drum insertion part 15 corresponds to the "1st trunk | drum insertion part" of this invention.

[Second Embodiment]
A second embodiment of the present invention will be described with reference to FIG. FIG. 7A is a front view of the spacer 11 according to the second embodiment of the present invention. The difference from the spacer 11 according to the first embodiment is that the body portion insertion portion 15 has a slit shape that is long in the upward direction (Y-axis direction).

  When the spacer 11 of the second embodiment is mounted on the pachinko machine 10, when the two game nails 43S are in the normal position, the head position indicating unit 16 overlaps the head 43h of the game nail 43S and is hardly visible. It becomes a state close to 5 (a). The difference from FIG. 5A is that the upper part of the trunk part insertion part 15 appears to protrude from above the game nail 43S. When the two game nails 43S are at a position lower than the normal position, not only the upper part of the trunk insertion part 15 but also a part of the head position indicating part 16 (depending on the degree of the low) Appears to protrude.

  When the two game nails 43S are at a position higher than the normal position, unlike FIG. 6 (d), the lower end 11a is not shown in the first start opening 47 because the trunk portion insertion portion 15 is long in the upward direction. (If the height is too large, the spacer 11 is in a floating state as in FIG. 6D). And the trunk | drum insertion part 15 which protrudes from the upper direction of the game nail 43S becomes small (it becomes completely invisible depending on the grade of height). A part of the head position indicating unit 16 can be seen from below the game nail 43S.

  Further, since the trunk portion insertion portion 15 is longer in the upward direction than the spacer 11 of the first embodiment, even when only one of the two game nails 43S is higher (or lower) than the normal position, 2 There is a high possibility that the body 43b of the game nail 43S can be positioned in the body insertion part 15 together. In that case, by checking whether or not the head 43 h of the game nail 43 </ b> S is displaced with respect to the head position indicating unit 16 with the lower end 11 a of the spacer 11 being in contact with the upper end 47 a of the first start port 47. Whether or not there is a deviation from the normal position can be determined.

[Third embodiment]
A third embodiment of the present invention will be described with reference to FIG. FIG. 7B is a front view of the spacer 11 according to the third embodiment of the present invention. The difference from the spacer 11 according to the first embodiment is that there is not a single knob 17 at the upper part of the spacer 11 but two protruding from the left and right of the spacer 11, and the vertical direction (parallel to the Y axis). (Direction) is smaller than the spacer 11 according to the first embodiment.

  In the game board 40 shown in FIG. 4, there is nothing that prevents the rolling of the game ball above the game nail 43S. However, depending on the game machine, a normal symbol operation gate 46 or the like is arranged above and near the game nail 43S. Some have done. In such a gaming machine, there is a possibility that the knob 17 of the spacer 11 according to the first embodiment becomes an obstacle to wearing, or the main body of the spacer 11 (the part excluding the knob 17) becomes an obstacle. Like the spacer 11 according to the third embodiment, the knobs 17 are arranged on the left and right sides, and the vertical dimension is made small, so that it can be mounted on a pachinko machine where the space above the game nail 43S is narrow. It becomes.

[Fourth embodiment]
A fourth embodiment of the present invention will be described with reference to FIG. FIG. 7C is a front view of the spacer 11 according to the fourth embodiment of the present invention. The difference from the spacer 11 according to the first embodiment is that marks 18 and 18 indicating the position of the upper end 47a of the first starting port 47 are formed on the lower end 11a.

  As described above, by using the spacer 11 according to the first embodiment, the game nail 43S is shifted in the vertical direction from the upper end 47a of the first start port 47, or the two game nails 43S are It can be detected that the interval is not a regular value. However, the two game nails 43S are substantially the same in the lateral direction (the direction parallel to the X-axis) (“substantially” means that the two body parts 43b can be inserted through the corresponding body part insertion parts 15 together. This means that an error of a certain level is allowed). If there is a deviation, the deviation cannot be detected by the spacer 11 of the first embodiment. The same applies to the spacers 11 of the second and third embodiments.

  In this regard, according to the spacer 11 according to the fourth embodiment, since the marks 18 and 18 indicating the position of the upper end 47a of the first starting port 47 are formed on the lower end 11a, the two game nails 43S are arranged in the lateral direction. Even when the amount of deviation is almost the same, the deviation can be detected. The marks 18 and 18 correspond to the “contact position instruction section” of the present invention. The marks 18 and 18 may be formed by printing on the lower end 11a of the spacer 11 or in the vicinity thereof, may be a seal attached to the same portion, or may be formed by surface processing by laser or etching. Alternatively, it may be raised on the surface of the spacer 11 in a relief shape.

[Fifth embodiment]
A fifth embodiment of the present invention will be described with reference to FIG. FIG. 7D is a front view of the spacer 11 according to the fifth embodiment of the present invention. The spacer 11 of this embodiment is close to the spacer 11 according to the fourth embodiment, and the difference is that recesses are formed at locations corresponding to the marks 18 and 18. When the spacer 11 is attached to the pachinko machine 10, the bottom surface (positionally upper surface) 19 of the recess comes into contact with the upper end 47 a of the first start port 47. Therefore, in the spacer 11 according to the fifth embodiment, the position of the lower end 11a is lower than the spacer 11 according to the first to fourth embodiments by the depth of the recess.

  According to the spacer 11 according to the fifth embodiment configured as described above, the same effects as those of the spacer 11 according to the fourth embodiment can be obtained. In the pachinko machine 10 in which the decorative plate 12 is provided at the first start port 47, the marks 18 and 18 of the spacer 11 according to the fourth embodiment may be difficult to see. In that case, it can be considered that the marks 18 and 18 are enlarged upward or looked in from above to determine whether the positions of the marks 18 and 18 and the upper end 47a of the first starting port 47 coincide. In this regard, according to the spacer 11 according to the fifth embodiment, since the concave portion is fitted into the upper end 47a of the first starting port 47, even if the decorative plate 12 is present, it does not look into from above. It can be determined whether or not the two game nails 43S are not substantially displaced in the horizontal direction. In the fifth embodiment, the “contact portion” of the present invention corresponds to the bottom surface 19 instead of the lower end 11a.

[Sixth embodiment]
A sixth embodiment of the present invention will be described with reference to FIGS. First, FIG. 8A is a front view of the spacer 11 according to the sixth embodiment of the present invention. Unlike the spacers 11 according to the first to fifth embodiments, the spacer 11 according to the present embodiment does not include the head insertion portion 14. Two slits 23 are formed from the lower end 11 a of the spacer 11. According to the spacer 11 configured in this way, it is not necessary to fit the spacer 11 from the front of the game nail 43S, and it is only necessary to insert the spacer 11 from above the game nail 43S. Then, by checking whether the position of the head 43 h of the game nail 43 </ b> S when the lower end 11 a of the spacer 11 is brought into contact with the upper end 47 a of the first start port 47 is not deviated from the position of the head position indicating unit 16. It can be determined whether or not the game nail 43S is in the normal position. The slit 23 corresponds to the “second body portion insertion portion” of the present invention.

  Then, by taking advantage of the feature that it can be mounted by inserting from above the game nail 43S, the spacer 11 as shown in FIGS. 8B to 8C can be configured. FIG. 8B is a front view of the spacer 11, and FIG. 8C is a view of FIG. 8B viewed from below. The spacer 11 is not a plate but a block. The two game nails 43 </ b> S are not perpendicular to the game board 40, but are planted in a shape that is open in a C shape (the narrow side is the game board 40 side) when viewed from above. In accordance with this, the slit 23 is formed in a C-shaped groove shape as shown in FIG.

  FIG. 9A is a right side view showing a state in which the spacer 11 is mounted on the corresponding pachinko machine. In addition, the same code | symbol is attached | subjected about the structure of the same name as 1st Example, such as a game nail and a 1st start port. The two game nails 43S are in the shape of a letter C when viewed from above or below, and are viewed horizontally when viewed from the side. As shown in the figure, the thickness of the spacer 11 is slightly thinner than the length of the trunk portion 43 b exposed from the game board 40. On the other hand, when the spacer 11 has a plate shape, for example, as shown in FIG. 5 (b), the spacer 11 to be mounted near the head 43h of the game nail 43S is attached to the body 43b of the game nail 43S. The position of the game nail 43S is changed by forcibly mounting it in the middle of the game, or the position of the game nail 43S is detoured by applying a force in the back direction to the spacer 11 mounted near the head 43h of the game nail 43S. There is a risk of changing.

  In this regard, the thickness of the spacer 11 according to the sixth embodiment is not a position to be originally mounted because it has a thickness that is slightly thinner than the length of the trunk portion 43b exposed from the game board 40. There is little risk that the position of the game nail 43S will be changed by attaching it to a location or applying an excessive force after installation. Further, since it is thicker than the plate-like spacer 11, it is relatively robust, and the possibility that the spacer 11 itself is deformed or damaged by mounting operation or the like is small.

  In addition, although 17 of the spacer 11 which concerns on 6th Example is provided only in the head 43h vicinity, you may form over the whole region of thickness direction (direction parallel to Z-axis). Further, the knob 17 may be formed only at substantially the center in the thickness direction. In this way, when the spacer 11 is detached, the spacer 11 can be easily grasped and the balance is good.

  Moreover, you may make the depth which forms the slit 23 into the position corresponding to the trunk | drum 43b in a regular position (FIG.9 (b)). In this configuration, if the body 43b abuts on the upper end of the slit 23 for mounting the spacer 11 and the body 43b of the game nail 43S is in the normal position, the lower end 11a of the spacer 11 is in contact with the upper end 47a of the first start port 47. It will abut. If the body portion 43b of the game nail 43S is higher than the normal position, the lower end 11a of the spacer 11 cannot contact the upper end 47a of the first starting port 47, and the spacer 11 of the second embodiment is shown in FIG. ) Will be the same as if it was floating. If the body 43b of the game nail 43S is at a position lower than the normal position, the head position indicating unit 16 protrudes from the top of the head 43h of the game nail 43S. As described above, it is possible to determine whether or not the game nail 43S is in the normal position also by the spacer 11 shown in FIG. 9B. Of course, marks 18 and 18 may be formed on the spacer 11 shown in FIG. 8 or the spacer 11 shown in FIG. 9B like the spacer 11 of the fourth embodiment, or the spacer of the fifth embodiment. 11 may be provided with a recess.

[Seventh embodiment]
A seventh embodiment of the present invention will be described with reference to FIG. FIG. 10A is a front view of the spacer 11 according to the seventh embodiment of the present invention. The spacer 11 of this embodiment is similar to the spacer 11 of the sixth embodiment shown in FIG. 8A, but the upper end of the slit 23 is the normal position of the body 43b and the lower end 11a is more The difference is in the high position. It should be noted that the lower end 11a is at a high position only in the portion sandwiched between the two slits 23, and the other portion 24 is the same height as the spacer 11 of the sixth embodiment (position in the Y-axis direction). ). Therefore, when the spacer 11 according to the seventh embodiment is attached to the pachinko machine 10, the height of the portion 24 coincides with the height of the upper end 47a of the first start port 47 when the game nail 43S is in the normal position. When the game nail 43S is at a position higher than the normal position, for example, as shown in FIG. 10B, a gap g is provided between the portion 24 and the upper end 47a. On the contrary, when the game nail 43S is at a position lower than the normal position, the upper end 47a of the first starting port 47 is indented between the two parts 24, 24, and the low degree is large. The lower end 11 a contacts the upper end 47 a of the first start port 47.

  Also with such a spacer 11 according to the seventh embodiment, whether or not the game nail 43S is in the normal position can be determined from the positional relationship between the part 24 and the upper end 47a of the first start port 47. In the present embodiment, the lower end 11a is not a portion that should come into contact with the upper end 47a of the first start port 47, and therefore does not correspond to the “contact portion” of the present invention. The present embodiment shows an embodiment of the present invention that does not include an abutting portion. The portion 24 corresponds to the “winning hole position indicating portion” of the present invention, and the slit 23 is the “third body portion insertion portion of the present invention. Part.

[Eighth embodiment]
An eighth embodiment of the present invention will be described with reference to FIGS. 11 (a) and 11 (b). FIG. 11A is a front view of the spacer 11 according to the eighth embodiment of the present invention. The spacer 11 of the present embodiment is obtained by printing the horizontal stripe pattern 25 between the two trunk portion insertion portions 15 using the spacer 11 of the first embodiment as a transparent plastic plate member. The actual striped pattern 25 is formed at a narrower interval than that shown in FIG. 11A and is printed on both the front and back surfaces of the spacer 11. According to the spacer 11, when the interval between the two game nails 43S is narrower than the normal position, this can be easily determined.

  FIG. 11B is a plan view showing a state in which the spacer 11 is mounted on the pachinko machine 10 in such a case, and shows the vicinity of the striped pattern 25 in an enlarged manner. If the spacer 11 is forcibly mounted when the interval between the two game nails 43S is narrower than the normal position, the spacer 11 bends. In addition, in FIG.11 (b), this bending is emphasized and the printing of the striped pattern 25 is also exaggerated. When the spacer 11 is bent, the interval between the stripe patterns 25c and 25d inside the bend becomes larger than the interval between the stripe patterns 25a and 25b inside the bend. When the spacer 11 is viewed from the front (arrow V), the position of the front and back stripes 25 does not change much near the center in the left-right direction (X-axis direction). The position of 25 is greatly shifted. Accordingly, it can be determined that moire occurs and the spacer 11 is bent, that is, the interval between the two game nails 43S is narrower than the normal position. In addition, the spacer 11 may be bent unevenly. In this case, irregular moire occurs, so that it can be determined that the interval between the two game nails 43S is narrower than the normal position. Note that the direction of bending may be reversed depending on the manner of wearing, but the determination can be made in the same manner.

[Ninth embodiment]
A spacer for determining whether or not the position of the game nail 43 planted in the vicinity of the winning opening other than the first start opening 47 is in a normal position is also conceivable. An example of this is shown in FIG. 12 as a ninth embodiment. FIG. 12A is a front view showing the normal winning opening 45d and the game nails 43U, 43V, 43W, 43X, 43Y planted in the vicinity thereof. FIG. 12B is a front view of the spacer 11 according to the eighth embodiment of the present invention. The spacer 11 according to the present embodiment is a plate-like member, and a head insertion portion 14 is formed at a slightly lower left of the center. In addition, since this spacer 11 is not provided with the trunk | drum insertion part, the head insertion part 14 is corresponded also to the "game nail insertion part" of this invention. On the upper right of the spacer 11, a body contact portion 26 that is an arc-shaped depression is formed.

  The spacer 11 is attached to the pachinko machine 10 as shown in FIGS. 12 (c) and 12 (d). That is, first, the spacer 11 is rotated counterclockwise by a predetermined angle (90 degrees in FIG. 12C), and the game nail 43U is inserted into the head insertion portion 14. If the spacer 11 is not rotated by a predetermined angle, the game nail 43V and the game nail 43w are obstructed and are difficult to mount. Next, the spacer 11 is rotated clockwise so that the body abutting portion 26 is brought into contact with the body 43b of the game nail 43V and the lower end 11a is brought into contact with the upper end 45a of the normal winning opening 45d (FIG. 12D). )).

  At this time, if the head insertion part 14 protrudes from the periphery of the head 43h of the game nail 43U when viewed from the front, it can be determined that the game nail 43U is not in the normal position. Moreover, if the head 43h of the game nail 43U and the head insertion part 14 are exactly overlapped, it can be determined that the distance between the game nail 43U and the game nail 43V is appropriate. Note that the distance between the game nail 43U and the game nail 43V (more precisely, the inner distance between the body portions of both game nails) is the size of the entrance of the normal winning opening 45d. Therefore, according to the spacer 11, it can be easily confirmed that the size of the entrance of the normal winning opening 45d is appropriate.

  A modification of the spacer 11 of FIG. 12 is shown in FIG. The spacer 11 shown in FIG. 13A has a step 27 at its lower end 11a. The procedure for attaching the spacer 11 to the pachinko machine 10 is the same as that of the spacer 11 shown in FIG. 12. First, as shown in FIG. 13B, the spacer 11 is turned counterclockwise by a predetermined angle (90 degrees in this figure). The game nail 43U is inserted through the head insertion part 14 by rotating. Next, the spacer 11 is rotated clockwise to bring the trunk contact portion 26 into contact with the trunk portion 43b of the game nail 43V, and the step 27 is brought into contact with the inner side of the upper end 45a on the left side of the normal winning opening 45d (FIG. 13 (c)).

  This means that the position of the lower end 11a is lower than the spacer 11 shown in FIG. 12, and the vertical dimension is larger in the spacer 11 shown in FIG. Although such a spacer 11 seems to be difficult to rotate from the state of FIG. 13B to the state of FIG. 13C while the game nail 43U is inserted through the head insertion portion 14, Since there is a gap between the head insertion portion 14 and the body portion 43h of the game nail 43S, the state of FIG. 13 (b) is changed to the state of FIG. 13 (c) by appropriately moving the spacer 11 up and down and left and right. It is possible to do. The same applies to the spacer 11 shown in FIG. However, this means that the spacer 11 in FIG. 12 can be slightly moved up and down and left and right even in the state of FIG. 12D, and the contact of the lower end 11a with the upper end 45a and the game nail There is also a side where it is not natural to position the spacer 11 at a fixed position only by contact with the 43V body contact portion 26.

  In this regard, according to the spacer 11 shown in FIG. 13, the position of the spacer 11 in the left-right direction can be determined by bringing the step 27 into contact with the inner side of the upper end 45 a on the left side of the normal winning opening 45 d. Can be more reliably positioned at a fixed position. In place of the step 27, a protrusion may be provided at the lower end 11a of the spacer 11 in FIG. Instead of the step 27, it is also conceivable that one recess similar to the recess of the spacer 11 of the fifth embodiment is formed at the lower end 11a and fitted into the upper end 45a on the left side of the normal winning opening 45d. Incidentally, when the game nail 43U is not present, the size of the entrance of the normal winning opening 45d is the distance between the upper end on the left side of the normal winning opening 45d and the game nail 43V (more precisely, the inner distance between the two). . Also for such a regular winning opening 45d, according to the spacer 11 shown in FIG. 13, it is possible to easily confirm that the distance between the upper end on the left side and the game nail 43V is appropriate. In addition, when confirming with respect to such a normal winning opening 45d, a spacer without the head insertion part 14 may be used.

  Further, the through hole 13 of the spacer 11 shown in FIG. 12 may be provided with a body insertion portion 15 above the head insertion portion 14 like the spacer 11 shown in FIG. The spacer 11 is attached to the pachinko machine 10 as follows. First, as shown in FIG. 12C, the spacer 11 is rotated counterclockwise by a predetermined angle, and the game nail 43 </ b> U is inserted through the head insertion portion 14. Next, the spacer 11 is moved to the right, and the body portion of the game nail 43U is brought into contact with the body insertion portion 15. Then, with the corresponding contact, the spacer 11 is rotated clockwise, the body abutment portion 26 is brought into contact with the body portion 43b of the game nail 43V, and the step 27 is placed inside the upper end 45a on the left side of the normal winning opening 45d. The contact is made (FIG. 12D). If it carries out like this, the head insertion part 14 (namely, spacer 11) will not move unnecessarily around the trunk | drum of the game nail 43U during the said rotation. Therefore, it is possible to prevent the spacer 11 from colliding with the game nail 43V or the game nail 43W due to the movement and damaging the spacer 11 or changing the posture of these game nails.

  In addition, although the two recessed parts of the spacer 11 of 5th Example were formed in the lower end 11a, it is also considered to form only one wide recessed part like the spacer 11 shown in FIG.13 (d). If the width of this recess is the same as the width of the first start opening 47, the game nail 43S will be displaced in either the left or right direction when the spacer 11 shown in FIG. 13 (d) cannot be mounted on the pachinko machine 10. Can be determined.

[Other embodiments]
