Description

  The present invention relates to a launching handle for a gaming machine and a gaming machine equipped with the launching handle.

  For example, the launch handle of a pachinko machine (game machine) is formed in a bowl shape such as a pseudo hemispherical shape that opens on one side, and is fixed to the pachinko machine with the openings facing each other. A pair of fixing members that can be held with fingers are provided. The pair of fixing members includes a cap on the front side (player side) and a grip body on the rear side (game machine side), and further, pivots around a rotational axis in the front-rear direction. An operable rotation lever (rotation operation member) is disposed.

  In such a launch handle, a predetermined dimension is provided in the direction of the rotation axis between the rotation lever and the cap and between the rotation lever and the grip body so that the rotation lever can be smoothly rotated. An axial gap having a (width dimension) is formed. However, such a gap in the axial direction is easily used by the player to insert a foreign object such as a coin or a match stick to fix the rotating lever. Such insertion of foreign objects may cause the lever to be twisted and prevent smooth rotation, deformation or damage to the fixing member, widening of the axial gap, deformation or peeling of the metal part. If this happens, the rotation angle of the rotating lever may be poorly detected, or the human body (player's hand) may or may not be touched (touch sensing), which may result in inability to launch the game ball and poor launch strength adjustment. Become. As a result, the durability (lifetime) of the launch handle is shortened, and the launch handle must be frequently replaced, which affects the durability of the entire pachinko machine.

  Therefore, in a gaming machine equipped with a launching handle for launching a game medium (game ball) like a pachinko machine, a foreign object such as a coin or a match stick is inserted into the axial gap to fix the rotation lever. It is demanded to prevent (block) such acts, and various solutions have been proposed. For example, the act of inserting and fixing foreign matter such as coins and match sticks in the axial gap by an extension that extends parallel to the rotary axis from the main body of the rotary lever (operation lever) and covers the axial gap. In addition to preventing (blocking), it is disclosed to form a radial gap that makes it difficult to insert and fix a foreign object compared to the axial gap (see Patent Document 1).

Japanese Utility Model Publication No. 61-127780

  According to Patent Literature 1, a certain result can be obtained in the prevention of the above-described action. However, since the pivot lever has a symmetrical shape in the pivot axis direction (front-rear direction), when the operator installs the pivot lever between the cap and the grip body, As a result, the axial gap and the radial gap may deviate from the specified dimensions (set values). Even if an assembly error can be found during inspection after assembly or during assembly work, the cycle time (tact time) for repair becomes longer and the product yield deteriorates, resulting in an increase in manufacturing cost. Will be invited.

  An object of the present invention is to prevent an assembly error of a rotating operation member with a simple configuration, and to prevent a prolonged cycle time and a deterioration in product yield by forming a predetermined axial gap and a radial gap. Another object of the present invention is to provide a launching handle for a gaming machine that can suppress an increase in manufacturing cost and a gaming machine having the same.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, a launch handle for a gaming machine according to the present invention includes:
A fixing member that is formed in a bowl shape that opens on one side and is fixed to the gaming machine;
It is arranged so as to be rotatable around a rotation axis in the front-rear direction with the player side as the front side and the gaming machine side as the rear side, and from the end surface of the opening peripheral wall portion of the fixing member to the periphery from its own center portion An axial gap having a predetermined dimension in the rotational axis direction is formed between the end surface of the main body portion extending in the radial direction to the portion and gripped by the player and formed on the outer peripheral surface. In a launching handle for a gaming machine comprising a rotation operation member arranged in
The main body portion of the rotation operation member is formed with an extending portion extending in parallel with the rotation axis so as to cover the axial gap from the outside in the radial direction,
The rotating operation member forms at least the main body while the inner peripheral surface of the extending portion forms a radial gap having a predetermined dimension in the radial direction between the outer peripheral surface of the opening peripheral wall portion of the fixing member. The outer diameter of the portion is reduced in diameter toward the front side in the rotation axis direction.

  In the gaming machine launch handle, an extending portion is formed extending from the main body of the rotating operation member (for example, a rotating lever) in parallel with the rotating axis and covering the axial gap from the outside in the radial direction. The inner peripheral surface forms a radial clearance with the outer peripheral surface of the opening peripheral wall portion of the fixing member (for example, cap or grip body). In addition, as the outer diameter of the main body portion is reduced toward the front side (continuously or intermittently), it becomes difficult for the operator to mistake the assembling direction (front-rear direction) when assembling the rotating operation member. Even in such a configuration, the axial gap and the radial gap are maintained at specified dimensions (set values). Therefore, it is difficult to perform an action of inserting and fixing a foreign object such as a coin or a match stick with respect to the radial gap thus formed (of course, also to the axial gap). In other words, if the operator notices a mistake in the direction of assembly of the rotating operation member, the operator can immediately correct the orientation, so that the cycle time (tact time) for repair and the deterioration of product yield are suppressed, and the manufacturing cost increases. Can be suppressed.

  In addition, since the outer diameter of the main body portion of the rotation operation member decreases toward the front side (continuously or intermittently), the player can grasp the rotation operation member and perform the rotation operation. A feeling of fitting improves and a player's feeling of fatigue is reduced. Therefore, the frequency of performing the action of inserting / fixing a foreign object in the radial gap is reduced, and the radial gap is enlarged, the fixing member (opening peripheral wall) is deformed / damaged, and the metal part is deformed / peeled. The moving operation member can be smoothly rotated, and the radial gap can be stably maintained over a long period of time, thereby improving durability. In addition, poor detection of the rotation angle of the rotating operation member, poor detection of the presence / absence of touch (touch sensing) of the human body (player's hand), etc. are less likely to occur, resulting in inability to launch game balls and poor launch strength adjustment. It becomes difficult to do. As a result, the durability (life) of the launch handle is improved, and the launch handle need not be frequently replaced, so that the durability of the entire gaming machine is also improved.

  When the rotation axis of the rotation operation member is arranged in the front / rear direction with the player side as the front side and the gaming machine side as the rear side, it is arranged in the middle direction (oblique direction) of the front / rear / up / down / left / right. There is. In addition, the launch handle for the gaming machine is constituted by a rotation operation member (for example, a rotation lever) and a pair of fixing members (for example, a cap and a grip body), for example, a rotation operation member that also serves as a cap and a grip body. And may consist of

Therefore, for example, a rotation operation member (rotation lever) that can be rotated around a rotation axis in the front-rear direction is disposed between a pair of fixing members including a front cap and a rear grip body. Can be used as a launch handle for gaming machines. At that time, for example, a method of arranging the pair of fixing members and the rotation operation member includes:
(1) A method in which a sphere (including a pseudo sphere) is separated after cutting along a plane including a diameter, and a rotating operation member is disposed between them;
(2) A method in which a sphere (including a pseudo sphere) is cut by two cut surfaces that are parallel to a plane including a diameter, and an intermediate member between the cut surfaces is removed, and then a rotation operation member is disposed;
(3) A method of separating a spheroid (including a pseudo spheroid) after cutting along a plane including a major axis (principal axis), and disposing a rotating operation member therebetween;
(4) A spheroid (including a pseudo spheroid) is cut by two cut surfaces spaced in parallel from a plane including the major axis (main axis), and the intermediate body between the cut surfaces is removed to rotate. A method of arranging the operation members;
Etc. Of course, the fixing member may have a shape other than a sphere or a spheroid (for example, a connected curved surface formed of a plurality of curved surfaces having different curvatures).

Therefore, the above-mentioned launch handle for gaming machines is specifically,
Each is formed into a bowl shape that opens entirely on one side and closes in whole or in part on the other side, and when the player side is the front side and the gaming machine side is the rear side, the openings are facing each other A pair of fixing members that are arranged in the front-rear direction so as to face each other and are fixed to the gaming machine;
Between the pair of fixing members, they are arranged so as to be rotatable around a rotation axis in the front-rear direction (and in the horizontal direction), and from the end surface of the opening peripheral wall portion of each fixing member to the peripheral portion from its own central portion An axial gap having a predetermined dimension in the rotational axis direction is formed between the end surface of the main body portion extending in the radial direction and gripped by the player and formed on the outer peripheral surface. In a launch handle for a gaming machine comprising a rotation operation member arranged,
The main body portion of the rotation operation member is formed with an extending portion extending in parallel with the rotation axis so as to cover the axial gap from the outside in the radial direction (in a bowl shape),
The rotating operation member forms a (cylindrical) radial gap having a predetermined dimension in the radial direction between the inner peripheral surface of the extension portion and the outer peripheral surface of the opening peripheral wall portion of the fixing member. On the other hand, at least the outer diameter of the main body may be reduced (continuously or intermittently) toward the front side in the rotation axis direction.

Moreover, in order to solve the above-mentioned problem, the launch handle for the gaming machine of the present invention is:
Each is formed into a bowl shape that opens entirely on one side and closes in whole or in part on the other side, and when the player side is the front side and the gaming machine side is the rear side, the openings are facing each other A pair of fixing members that are arranged in the front-rear direction so as to face each other and are fixed to the gaming machine;
Between the pair of fixing members, they are arranged so as to be rotatable around a rotation axis in the front-rear direction (and in the horizontal direction), and from the end surface of the opening peripheral wall portion of each fixing member to the peripheral portion from its own central portion An axial gap having a predetermined dimension in the rotational axis direction is formed between the end surface of the main body portion extending in the radial direction and gripped by the player and formed on the outer peripheral surface. In a launch handle for a gaming machine comprising a rotation operation member arranged,
The main body portion of the rotating operation member is formed with extending portions extending in parallel with the rotating axis so as to cover each axial gap from the outside in the radial direction (in a bowl shape over the entire circumference). And
The rotation operation member has a (cylindrical) radial gap having a predetermined dimension in the radial direction between the inner peripheral surface of each extending portion and the outer peripheral surface of the opening peripheral wall portion of the corresponding fixing member. On the other hand, at least the outer diameter of the main body decreases toward the front side in the rotation axis direction (continuously or intermittently),
Furthermore, the inner diameter of the extension part on the front side is smaller than the inner diameter of the extension part on the rear side, and the outer diameter of the opening peripheral wall part of the fixing member arranged on the front side is fixed on the rear side. It is characterized by being formed smaller than the outer diameter of the opening peripheral wall portion of the member.

  Even in such a launching handle for a gaming machine, if the operator notices a mistake in the direction of assembly of the rotating operation member, the operator can immediately correct the orientation, thereby prolonging the cycle time (tact time) for repair and increasing the product yield. Deterioration can be suppressed and an increase in manufacturing cost can be suppressed. In addition, since the outer diameter of the main body portion of the rotation operation member decreases toward the front side (continuously or intermittently), the player can grasp the rotation operation member and perform the rotation operation. A feeling of fitting improves and a player's feeling of fatigue is reduced. Therefore, the frequency of performing the action of inserting and fixing foreign matter in the radial gap is reduced. As a result, the durability (life) of the launch handle is improved, and the launch handle need not be frequently replaced, so that the durability of the entire gaming machine is also improved.

  Moreover, the inner diameter of the extension part on the front side is formed smaller than the inner diameter of the extension part on the rear side, and the outer diameter of the opening peripheral wall part of the fixing member arranged on the front side is arranged on the rear side. By forming it smaller than the outer diameter of the opening peripheral wall portion of the fixing member, it is possible to clearly recognize a mistake in the assembling direction of the rotating operation member and prevent an assembling error in advance. In addition, it becomes easy to form axial gaps and radial gaps arranged at the front and rear of the main body so as to have minute dimensions in which foreign matter is not easily inserted and fixed.

  When the dimensional difference as described above is provided, it is easy to make the former smaller than the latter when comparing the average diameter of the radial gap on the front side and the average diameter of the radial gap on the rear side. As a result, the thickness of the front and rear opening peripheral wall portions and the front and rear extension portions are kept uniform, and a thin portion is not formed in a specific part, so that the durability of the entire launch handle can be improved in a balanced manner. Become.

Furthermore, in the launch handle for the gaming machine,
The outer peripheral surface of the main body and the outer peripheral surface of the extending portion constitute a continuous or intermittent tapered surface, and the gripping surface is formed across the outer peripheral surface of the main body and the outer peripheral surface of the extending portion. Is desirable.

  As described above, the outer peripheral surface of the main body portion and the outer peripheral surface of the extending portion constitute a continuous or intermittent tapered surface, so that it is more difficult to make a mistake in the assembly direction of the rotating operation member. Therefore, the manufacturing cost can be further suppressed. Specifically, if the outer peripheral surface of the main body portion and the outer peripheral surface of the extension portion are continuously formed on a tapered surface having a common taper ratio or intermittently formed on tapered surfaces having different taper ratios, The main body portion and the extension portion of the moving operation member have a truncated cone shape, and for example, the rotation operation member can be easily manufactured by integral molding.

  The “taper” used here is a draft angle (draft slope, allowance) provided to facilitate removal of a molded product from a mold when a polymer material (for example, synthetic resin) is integrally molded by injection molding or the like. Is generally set larger. Usually, the draft angle is about 1/60 to 1/40 (the taper ratio is 1/30 to 1/20, and the taper angle is about 2 ° to 3 °). By setting the ratio to about 1/10 to 1/3 (about 5 ° to 20 ° in taper angle), in addition to assemblability during work and operability during game play, design is also improved.

  Further, when the radial gap is formed over the entire circumference of the extending portion, it becomes easier to prevent the foreign matter from being inserted. Furthermore, when the finger hook portion that protrudes outward in the radial direction from the gripping surface (outer peripheral surface) of the main body portion is disposed within the full width of the main body portion in the rotation axis direction, the finger hook portion rotates around the fulcrum. It becomes more difficult to widen the radial gap by twisting the operating member.

  The radial gap as described above may constitute an expanded gap whose dimension in the radial direction increases at least partially with respect to the width of the extending portion in the rotational axis direction toward the distal end of the extending portion. Good.

  As a result, foreign matter such as coins and match sticks inserted into the expansion gap is likely to fall mainly inward or outward in the radial direction due to its own gravity, thereby making it easy to prevent foreign matter from being inserted and fixed. The expanding gap may be formed by gradually reducing the outer diameter of the fixing member due to the curvature of the fixing member.

At that time, the outer diameter of the opening peripheral wall portion of the fixing member gradually increases in a section extending from the end surface of the opening peripheral wall portion to a position that is a predetermined distance away from the opening in the rotational axis direction. By diameter, it is positioned closer to the base side than the tip position (end face position) of the extension part (when the opening peripheral wall part is viewed from the end face side, the apparent total thickness of the opening peripheral wall part is set in the radial direction. Step) is formed,
In the first gap forming portion that reaches the stepped portion on the base side of the extending portion, the radial gap forms a parallel gap that is parallel to the rotation axis and has a constant radial dimension, and extends from the stepped portion. In the second gap forming portion that reaches the tip (end surface) of the protruding portion, an expanding gap in which the radial dimension increases toward the tip of the extending portion may be configured.

  As a result, the insertion tip of the foreign object is caught by the step portion, and it becomes difficult to widen the axial clearance by twisting the rotation operation member. In addition, it becomes difficult for foreign matter to be inserted into the radial gap due to the stepped portion, and it is difficult to widen the radial gap. Further, since the apparent total thickness of the opening peripheral wall portion increases in the radial direction at the stepped portion, the contactable area with the rotating operation member increases, the strength of the opening peripheral wall portion increases, deformation, damage, etc. Less likely to occur. Furthermore, by forming the radial gap in two stages, foreign matter such as coins and match sticks inserted into the widening gap is likely to fall mainly inside or outside in the radial direction due to its own gravity.・ It becomes easy to prevent fixation.

  Note that “the apparent total thickness of the opening peripheral wall portion when the opening peripheral wall portion is viewed from the end surface side” is “the opening peripheral wall portion expressed when the opening peripheral wall portion is projected onto a plane orthogonal to the rotation axis”. In other words, the apparent total thickness.

  When the width dimension in the rotation axis direction of the second gap forming portion corresponding to the widening gap is smaller than the width dimension in the rotation axis direction of the first gap forming portion corresponding to the parallel gap. This makes it easier for the foreign matter inserted into the expansion gap to fall down and further prevent the foreign matter from being inserted and fixed. Further, the stepped portion is desirably formed over the entire circumference of the opening peripheral wall portion of the fixing member, which makes it easier to prevent foreign matter from being inserted and fixed.

  Alternatively, the radial gap described above is formed on an inclined surface that is inclined outward in the radial direction as the inner peripheral surface of the extending portion is directed toward the tip, thereby extending over the entire width of the extending portion in the rotation axis direction. You may comprise the expansion gap from which the dimension of a radial direction becomes large as it goes to the front-end | tip of a part.

  By the inclined surface formed on the inner peripheral surface of the extension portion, the radial dimension of the expansion gap can be relatively increased, and foreign matter such as coins and match sticks inserted into the expansion gap is his / her own. Gravity makes it easy to fall mainly inside or outside in the radial direction, and it becomes easy to prevent foreign matter from being inserted and fixed. In addition, if used together with an expansion gap formed by gradually reducing the outer diameter of the fixing member due to the curvature of the fixing member, the radial dimension of the expansion gap will be further increased. It becomes easy to prevent.

Therefore, in order to solve the above problems, the gaming machine of the present invention is:
A launch handle for a gaming machine as described above is provided.

  Thus, the assembly direction (front-rear direction) can be changed when the operator installs the rotation operation member only by reducing the outer diameter of the main body of the rotation operation member (for example, the rotation lever) toward the front side. It becomes difficult to mix them up, and the axial gap and the radial gap are maintained at specified dimensions (set values) even with a simple configuration. Therefore, it is difficult to perform an action of inserting / fixing foreign matter such as coins and match sticks in the radial gap. In addition, the feeling of fitting when the player holds and rotates the rotation operation member is improved, and the player's feeling of fatigue is reduced. Therefore, the frequency of the action of inserting and fixing foreign objects in the radial gap is reduced, the durability (life) of the launch handle is improved, and the launch handle does not need to be frequently replaced. Also improves.

(Example 1)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view illustrating a pachinko machine equipped with a launching handle for gaming machines (hereinafter also simply referred to as a launching handle) according to the present invention. As shown in FIG. 1, on the board surface (front surface) of the game board 2 of the pachinko machine 1 (game machine), the left half of the circumference is partitioned by two inner and outer launch rails 2b to form a circular game area 2a as a whole. Has been. A liquid crystal display unit 3 is mounted at the center of the game area 2a, and a big winning device 4 (winning device) is disposed below the liquid crystal display unit 3 (lower center of the game region 2a). In addition, a start winning device 5 composed of an electric tulip (electric Chu) is disposed between the liquid crystal display unit 3 and the big winning device 4. Further, a lower right portion of the pachinko machine 1 is operated by a player in order to fire a game ball by operating a ball striking device (launching device; not shown) by driving means (not shown) such as an electric motor. A firing handle 6 is attached.

  In this specification, the up and down direction means a direction (for example, a vertical direction) in which the game ball flows down along the board surface of the game board 2. Further, the left-right direction means a direction (for example, a horizontal direction) intersecting with the up-down direction in a form along the board surface of the game board 2, and means the left side and the right side when viewed from the player side. Further, the front-rear direction means a direction intersecting (for example, orthogonal) with the game board 2, the player side (front side) is the front side, and the game machine 1 side (back side), which is the opposite side, is the rear side. Become the side.

  2 is a front view and a bottom view showing an example of a firing handle according to the present invention, FIG. 3 is an exploded perspective view showing the firing handle, and FIG. 4 is a half sectional view in side view. As shown in FIGS. 2 and 3, the grip body 10 (fixing member) and the cap 20 (fixing member) are fixed to the pachinko machine 1, and a rotation lever 30 (rotation) is provided between the grip body 10 and the cap 20. Operating members), which constitute the main part of the firing handle 6.

  The grip body 10 is formed in a bowl shape that is open in a circular shape entirely on one side and partially closed on the other side, and its mounting portion 13 is fixed to the gaming machine 1 (see FIG. 1). The cap 20 is formed in a bowl shape that opens in a circular shape entirely on one side and is entirely closed on the other side, and is fixed to the grip body 10 by a plurality of (for example, three) mounting screws B (fastening members). ing. Specifically, the grip body 10 is disposed on the rear side and the cap 20 is disposed on the front side so that the openings face each other and face each other like a palm.

  The rotation lever 30 is rotatably disposed around a rotation axis O in the front-rear direction (for example, the horizontal direction), extends in the radial direction from the center to the periphery, and has a gripping surface 32 gripped by the player. It has the main-body part 31 formed in the surface. A plurality of (for example, three) finger hooks 33 project in a square shape from the gripping surface 32 (outer peripheral surface) of the main body 31 toward the outer side in the radial direction, and these finger hooks 33 are formed in the direction of the rotation axis O. It arrange | positions within the full width of the main-body part 31 (gripping surface 32) (refer FIG.2 (b)). In addition, a torsion coil spring 34 (biasing means) is stretched between the rotation lever 30 and the cap 20 in order to pull the rotation lever 30 back to the rotation reference position (game standby state). Further, in order to detect the rotation angle of the rotation lever 30 and adjust the launch strength of the game ball, the rotation shaft 35a of the variable resistor 35 (rotation angle detector) has its center aligned with the rotation axis O. In form, it is fixed to the turning lever 30.

  An internal cap 23 (fixing member) fixed to the inside of the cap 20 is for holding the rotating lever 30, the torsion coil spring 34, and the like (see FIG. 4). Further, in order to detect whether or not the player's hand is in contact, a part of the outer peripheral surface of the grip body 10 or the rotation lever 30 may be plated.

  As shown in FIG. 4, the end surface 11 a of the opening peripheral wall portion 11 of the grip body 10 and the rear end of the body portion 31 of the rotation lever 30 in order to enable the rotation lever 30 to rotate with respect to the grip body 10. An axial gap SA having a predetermined dimension (for example, 0.5 mm) in the rotation axis O direction is formed in an annular shape in the front-rear direction between the cut-out bottom surface 31b (end surface) on the part side.

  The main body 31 of the rotation lever 30 extends rearward in parallel with the rotation axis O so as to cover the axial gap SA from the outside in the radial direction, and forms an extension 320. In order to make the turning lever 30 turnable with respect to the grip body 10, it is between the notch wall surface 320 b (inner peripheral surface) of the extension portion 320 and the outer peripheral surface 11 b of the opening peripheral wall portion 11 of the grip body 10. The radial gap SR having a predetermined dimension in the radial direction is formed in a cylindrical shape in the front-rear direction. As the outer diameter gradually decreases due to the curvature of the grip body 10, the radial gap SR is an expanded gap SR <b> 2 whose radial dimension increases toward the rear end (end surface 320 c) of the extension portion 320. Is configured. Therefore, the axial gap SA and the radial gap SR have an L shape in cross section.

  In order to start a game in such a pachinko machine 1, the player holds the cap 20 of the firing handle 6 so as to wrap it in the palm of the hand, grasps the main body 31 (gripping surface 32) of the rotating lever 30, and moves the finger. The turning lever 30 is turned by putting a finger on the hanging portion 33. At this time, the launch strength is adjusted according to the rotation angle of the rotary lever 30 detected by the variable resistor 35, and a ball hitting basket (not shown) is operated to direct the game ball toward the game area 2a of the pachinko machine 1. Fired (fired).

  As shown in the enlarged view of FIG. 4, some players do not grasp the main body 31 (gripping surface 32) of the rotation lever 30, and the notched wall surface 320 b (inner peripheral surface) of the extension 320 and the grip body An act of launching a game ball in a state in which a foreign object such as a coin C is inserted from the lateral direction into the expansion gap SR2 formed between the outer peripheral surface 11b of the ten opening peripheral walls 11 and the rotating lever 30 is fixed. May try to try. However, foreign matter such as coins C inserted into the expansion gap SR2 falls downward (inward or outward in the radial direction) indicated by the arrow due to its own gravity, and it is difficult to fix the foreign matter in the expansion gap SR2. become.

  On the other hand, in order to enable the rotation lever 30 to rotate with respect to the cap 20, between the end surface 21 a of the opening peripheral wall portion 21 of the cap 20 and the front end surface 31 a of the main body portion 31 of the rotation lever 30. The axial gap SA having a predetermined dimension (for example, 0.5 mm) in the direction of the rotation axis O is formed in an annular shape in the front-rear direction.

  The opening peripheral wall portion 21 of the cap 20 reaches a position separated from the end surface 21a of the opening peripheral wall portion 21 in the rotation axis O direction by a predetermined distance (for example, 4.5 mm) forward (on the opposite side to the opening). In this section, a stepped portion 22 whose outer diameter is increased stepwise (stepwise) is formed over the entire circumference. Therefore, when the opening peripheral wall portion 21 is viewed from the end surface 21a side, the (apparent total) thickness of the opening peripheral wall portion 21 increases in the radial direction (vertical direction). Further, the end position on the front side (opposite side of the opening) in the step portion 22 of the cap 20 is more than the front end positions (end surface 320c position) of the extending portions 321 and 322 in the rotation lever 30 in the rotation axis O direction. It is arranged on the rear side (base side).

  The main body 31 of the rotation lever 30 extends to the front side in parallel with the rotation axis O so as to cover the axial gap SA from the outside in the radial direction, and forms extension portions 321 and 322. The extending portions 321 and 322 also cover the stepped portion 22 located on the front end side (front end side) with respect to the axial gap SA from the outside in the radial direction. In order to make the rotation lever 30 rotatable with respect to the cap 20, the inner peripheral surface 320 d of the extending portions 321 and 322, the outer peripheral surface 22 b of the stepped portion 22 of the cap 20, and the outer peripheral surface 21 b of the opening peripheral wall portion 21. A radial gap SR having a predetermined dimension in the radial direction is formed in a cylindrical shape in the front-rear direction.

  Specifically, the radial gap SR is parallel to the rotational axis O and has a constant radial dimension in the first gap forming portion 321 reaching the stepped portion 22 on the rear side (base side) of the extended portion. A parallel gap SR1 that is (for example, 0.5 mm) is formed. On the other hand, in the second gap forming part 322 extending from the step part 22 to the front end (end surface 320c) of the extension part, an expansion gap SR2 is formed in which the radial dimension increases toward the front end of the extension part. . And the width dimension b (for example, 1.0 mm) of the rotation axis O direction of the 2nd clearance gap formation part 322 (formation area of the expansion clearance SR2) is the 1st clearance gap formation part 321 (formation area of the parallel clearance SR1). ) In the rotational axis O direction (b <a) (b <a). Here, the outer diameter is gradually reduced by the curvature of the cap 20 to form the expansion gap SR2. The axial gap SA and the parallel gap SR1 are L-shaped in cross section.

  As shown in the enlarged view of FIG. 4, the coin C is also applied to the widening gap SR2 formed between the inner peripheral surface 320d of the second gap forming portion 322 and the outer peripheral surface 21b of the opening peripheral wall portion 21. In some cases, an act of launching a game ball may be attempted in a state in which a foreign matter such as the above is inserted from the lateral direction and the rotation lever 30 is fixed. However, by forming the radial gap SR in two stages, that is, the parallel gap SR1 and the spread gap SR2, foreign matter such as coins C inserted into the spread gap SR2 is moved downward (radius) by its own gravity. In the direction), it becomes difficult to fix the foreign matter in the expansion gap SR2.

  Further, in the parallel gap SR1, the first gap forming portion 321 (inner peripheral surface 320d) of the rotating lever 30 and the outer peripheral surface 22b of the stepped portion 22 are parallel and located at a constant interval. (Thin) can be formed, and it becomes easy to prevent insertion of coins C and the like. Further, in the stepped portion 22, the (apparent total) thickness of the opening peripheral wall portion 21 increases in the radial direction, so that the contactable area with the end surface 31 a of the rotating lever 30 (main body portion 31) increases and the opening peripheral wall The strength of the portion 21 increases, and deformation and damage are less likely to occur.

  In FIG. 4 again, the main body portion 31 and the extension portions 320, 321, and 322 of the turning lever 30 are reduced in diameter toward the front side in the direction of the turning axis O. It has a trapezoidal shape. That is, the outer peripheral surface of the main body 31 and the outer peripheral surfaces of the extending portions 320, 321, and 322 constitute a continuous tapered surface (inclined surface) having a common taper ratio, and the gripping surface 32 is the outer periphery of the main body 31. It is formed across the surface and the outer peripheral surface of the extended portions 320, 321, 322. Specifically, the entire width of the main body 31 and the extending portions 320, 321, and 322 in the direction of the rotation axis O is L, the maximum outer diameter of the extending portion 320 on the rear end side is D1, and the extending portion 322 on the front end side. The taper ratio of the tapered surface 32 is represented by (D1-D2) / L, and is larger than the normal draft (for example, taper ratio≈1 / 10, taper angle α≈5). °) is set.

  Further, the inner diameter d2 of the front end side extending portion 322 is formed smaller than the inner diameter d1 of the rear end side extending portion 320 (d2 <d1), and the outer diameter D22 of the stepped portion 22 of the cap 20 is It is formed smaller than the maximum outer diameter D11 of the opening peripheral wall portion 11 of the grip body 10 (D22 <D11). Thereby, among the radial gaps SR formed before and after the main body 31 of the rotating lever 30, the average diameter of the front parallel gap SR1 is formed smaller than the average diameter of the rearward expansion gap SR2. ing.

  As described above, since the inner diameter d2 <the inner diameter d1 and the outer diameter D22 <the maximum outer diameter D11, it is difficult for the operator to mistake the assembling direction (front-rear direction) when assembling the rotating lever 30, and an assembling error occurs. Can be prevented in advance. Further, since the outer diameter of the main body 31 of the turning lever 30 is reduced toward the front side, the fit feeling when the player holds and turns the turning lever 30 is improved. A person's feeling of fatigue is reduced. Therefore, the frequency of performing the action of inserting / fixing a foreign object into the expansion gap SR2 is reduced, and as a result, the durability (life) of the firing handle 6 is improved and the firing handle 6 need not be frequently replaced. The durability of the entire gaming machine 1 is also improved.

(Modification 1)
FIG. 5 is an enlarged cross-sectional view showing a modification of the rotating lever. As shown in FIG. 5, in order to turn the turning lever 30 (turning operation member) relative to the grip body 10 (fixing member), the end surface 11 a of the opening peripheral wall portion 11 of the grip body 10 and the rotation An axial gap having a predetermined dimension (for example, 0.5 mm) in the direction of the rotation axis O (see FIG. 4) between the bottom end 31b (end face) on the rear end side of the main body 31 of the moving lever 30. SA is formed in an annular shape in the front-rear direction.

  The main body 31 of the rotation lever 30 extends rearward in parallel with the rotation axis O so as to cover the axial gap SA from the outside in the radial direction, and forms an extension 320. In order to make the turning lever 30 turnable with respect to the grip body 10, it is between the notch wall surface 320 b (inner peripheral surface) of the extension portion 320 and the outer peripheral surface 11 b of the opening peripheral wall portion 11 of the grip body 10. The radial gap SR having a predetermined dimension in the radial direction is formed in a cylindrical shape in the front-rear direction. As the outer diameter gradually decreases due to the curvature of the grip body 10, the radial gap SR is an expanded gap SR <b> 2 whose radial dimension increases toward the rear end (end surface 320 c) of the extension portion 320. Is configured. Therefore, the axial gap SA and the radial gap SR have an L shape in cross section.

  On the other hand, in order to make the rotation lever 30 rotatable with respect to the cap 20 (fixing member), the end surface 21a of the opening peripheral wall portion 21 of the cap 20 and the end surface 31a on the front side of the main body portion 31 of the rotation lever 30 are provided. Between the two, an axial gap SA having a predetermined dimension (for example, 0.5 mm) in the rotation axis O direction is formed in an annular shape in the front-rear direction.

  The main body 31 of the rotation lever 30 extends to the front side in parallel with the rotation axis O so as to cover the axial gap SA from the outside in the radial direction, thereby forming an extension 320. In order to allow the turning lever 30 to turn with respect to the cap 20, there is a predetermined radial direction between the inner peripheral surface 320 d of the extension portion 320 and the outer peripheral surface 21 b of the opening peripheral wall portion 21 of the cap 20. A radial gap SR having the following dimensions is formed in a cylindrical shape in the front-rear direction. The radial gap SR constitutes an expanded gap SR2 in which the radial dimension increases toward the front end (end face 320c) of the extension part 320 as the outer diameter gradually decreases due to the curvature of the cap 20. is doing. Therefore, the axial gap SA and the radial gap SR have an L shape in cross section.

  The main body part 31 and the front and rear extension parts 320, 320 of the rotating lever 30 have a plurality of (two in this case) cones with their outer diameters decreasing toward the front side in the rotating axis O direction. It has a shape in which a table is stacked on the front and back. In other words, the outer peripheral surface of the main body 31 and the outer peripheral surfaces of the extension portions 320 and 320 are intermittently tapered surfaces whose taper ratio (taper angle) changes at a midway portion (taper change point P) in the rotation axis O direction. The gripping surface 32 is formed across the outer peripheral surface of the main body 31 and the outer peripheral surfaces of the extending portions 320 and 320.

  Specifically, the width in the rotation axis O direction from the rear end face 320c to the taper changing point P is L1, the maximum outer diameter of the extending portion 320 on the rear side is D1, and the outer diameter of the main body 31 at the taper changing point P. Is D0, the taper ratio of the rear taper surface 32 is expressed by (D1-D0) / L1, which is considerably larger than the normal draft (for example, taper ratio≈1 / 4, taper angle α1≈15 °). Is set. On the other hand, the width in the rotation axis O direction from the taper change point P to the front end face 320c is L2, the outer diameter of the main body 31 at the taper change point P is D0, and the minimum outer diameter of the extension part 320 on the front side is D2. Then, the taper ratio of the front tapered surface 32 is represented by (D0−D2) / L2, and is set to be slightly larger than the normal draft (for example, taper ratio≈1 / 10, taper angle α2≈5 °). Yes.

  Further, the inner diameter d2 of the front extension 320 is formed smaller than the inner diameter d1 of the rear extension 320 (d2 <d1), and the maximum outer diameter D21 of the opening peripheral wall 21 of the cap 20 is The opening peripheral wall portion 11 of the grip body 10 is formed smaller than the maximum outer diameter D11 (D21 <D11). As a result, of the radial gaps SR formed before and after the main body 31 of the rotating lever 30, the average diameter of the front expansion gap SR2 is made smaller than the average diameter of the rear expansion gap SR2. Has been.

(Modification 2)
FIG. 6 is an enlarged cross-sectional view showing another modification of the rotating lever. As shown in FIG. 6, the main body 31 and the front and rear extension parts 320, 320 of the rotation lever 30 (rotation operation member) have an outer diameter in the direction of the rotation axis O (see FIG. 4). It has a single stratified volcano (lateral crater) shape that decreases in diameter toward the top. That is, the outer peripheral surface of the main body 31 and the outer peripheral surfaces of the extending portions 320 and 320 form a curved surface (inclined surface) whose curvature continuously changes in the direction of the rotation axis O, and the gripping surface 32 is the main body 31. Are formed across the outer peripheral surface of each of the extending portions 320 and 320. Specifically, the gripping surface 32 extends forward from the maximum outer diameter D1 of the rearward extension part 320 in the entire width L of the main body part 31 and the extension parts 320 and 320 in the rotation axis O direction. It exhibits a curved surface (inclined surface) that gradually changes to the minimum outer diameter D2 of the portion 322.

(Example 2)
FIG. 7 is a half sectional view in side view showing another example of the firing handle. In the turning lever 30 (turning operation member) of the launching handle 106 (game machine launching handle) shown in FIG. 7, the outer peripheral surface of the main body 31 and the outer peripheral surfaces of the front and rear extending portions 320, 320 are configured. The form of the tapered surface 32 (gripping surface) is the same as that of the first embodiment (FIG. 4). The forms of the axial gap SA and the radial gap SR are basically the same as in Modification 1 (FIG. 5).

  However, the radial gap SR on the rear side has a notch wall surface 320b (inner peripheral surface) of the rearward extending portion 320 at the rear end (end surface) in addition to the outer diameter gradually decreasing due to the curvature of the grip body 10. 320c) is formed with an inclined surface that is inclined outward in the radial direction, and thus, an expansion gap SR2 in which the radial dimension increases toward the rear end (end surface 320c) of the extension portion 320 is formed. ing. Similarly, the radial gap SR on the front side is gradually reduced in outer diameter due to the curvature of the cap 20, and the inner peripheral surface 320d of the extension part 320 on the front side is closer to the front end (end surface 320c). Along with the formation of the inclined surface that is inclined outward in the radial direction, an expanding gap SR2 is formed in which the radial dimension increases toward the front end (end surface 320c) of the extending portion 320. In addition, the maximum inner diameter d2 of the extension part 320 on the front side is formed smaller (d2 <d1) than the maximum inner diameter d1 of the extension part 320 on the rear side.

  Thus, in addition to the reduced diameter due to the bending of the grip body 10 and the cap 20, the radial dimension of the expansion gap SR <b> 2 is formed by the inclined surfaces formed on the inner peripheral surfaces 320 b and 320 d of the front and rear extension portions 320 and 320. Is relatively large. As shown in the enlarged view of FIG. 7, foreign matter such as coins C inserted into the expansion gap SR2 is likely to fall down (inside or outside in the radial direction) indicated by an arrow due to its own gravity, and the foreign matter is inserted.・ It becomes easy to prevent the act of fixing.
