  The present invention attaches a fixed object to a target object such as an island base on which a gaming machine is installed with a bolt, and prevents the fixed object and the bolt from being separated when the fixed object is removed from the target object. The present invention relates to a fixing device provided with a separation preventing member.

  Conventionally, a gaming machine such as a pachinko machine is installed in an installation space formed between a long plate-like upper island frame and a lower island frame provided on an island platform, and an island is tilted in the front-rear direction. It is designed to be fixed to the base. Depending on the adjustment of the inclination angle, the game balls of the gaming machine are greatly influenced. Therefore, the adjustment of the inclination angle is an important task in the game hall.

  By the way, in order to attach the gaming machine to the island base, it is generally performed by nailing the upper side portion and the lower side portion of the outer frame constituting the gaming machine. However, the fixing operation of the gaming machine must be performed within a range tilted once from the vertically upright state. Therefore, the fixing operation of the gaming machine is extremely difficult and skillful. It was work that required.

  Also, recently, in order to facilitate the fixing work of this gaming machine, the upper side of the outer frame is fixed to the island base with a nail or the like, while the inclination angle of the lower side of the outer frame is adjusted with a predetermined fixing device. The technique to fix is proposed (refer patent documents 1-3).

On the other hand, the separation preventing member prevents the fixed object and the screw shaft member from separating when the fixed object is removed from the object by loosening the screwing of the shaft portion by operating the head of the screw shaft member. To do.

  In the fixing device of the present invention configured as described above, the separation preventing member includes an insertion hole through which the shaft portion of the screw shaft member is inserted, and one end side of the insertion hole is substantially the same as the shaft portion of the screw shaft member. A locking portion formed in a diameter is provided. Accordingly, the shaft portion of the screw shaft member is inserted into the insertion hole of the fixed object and the insertion hole of the separation preventing member, and the screw shaft member is screwed by operating the head of the screw shaft member, so that the fixed object becomes the object. When attaching, the separation preventing member is positioned between the object and the fixed object, and the locking portion of the separation preventing member is locked to the shaft portion of the screw shaft member. That is, when the screw shaft member is screwed and the fixed object is attached to the object, the fixed object and the screw shaft member are integrally assembled by the separation preventing member, whereby the fixed object and the screw shaft member are separated. Is to prevent.

  Therefore, in the fixing device of the present invention configured as described above, when an unskilled operator operates the head of the screw shaft member and loosens the screw shaft member, the fixed object is removed from the object. Therefore, the fixed member and the screw shaft member are not separated from each other due to the screw shaft member falling off, and as a result, the screw shaft member can be prevented from being lost.

  In the fixing device according to claim 2, when the fixed member is attached to the object by screwing the screw shaft member, the separation preventing member is positioned between the object and the fixed object. The locking portion is locked to the distal end side of the fixed portion of the shaft portion of the screw shaft member, whereby the fixed object is screwed with the locking portion of the separation preventing member formed to have substantially the same diameter as the shaft portion of the screw shaft member. It will be in the state of being pinched and fixed with the head of a shaft member. Therefore, in the fixing device of the present invention configured as described above, the fixed object and the screw shaft member are more firmly assembled by the separation preventing member, and as a result, the fixed object and the screw shaft member are separated. It can prevent more reliably.

  Here, various specific configurations of the separation preventing member are conceivable, and for example, the following may be employed. In other words, the fixing device according to claim 3 uses a coil spring as the separation preventing member, and the coil spring has a tuna shape when the coil winding diameter is gradually reduced from one end side to the other locking portion side. If it is formed in a conical shape, the shaft portion of the screw shaft member is wound around. For this reason, the coil spring is arranged between the fixed object and the object with the engagement portion side having a small coil winding diameter on the head side (fixed object side) of the screw shaft member, and the coil spring having a large coil winding diameter. The side opposite to the stop portion can be disposed on the tip side (object side) of the shaft portion of the screw shaft member. In this state, the fixed object is firmly fixed by being sandwiched between the engaging portion of the end portion of the coil spring and the head portion of the screw shaft member that are formed to have substantially the same diameter as the shaft portion of the screw shaft member. It becomes.

  Therefore, in the fixing device of the present invention configured as described above, the separation preventing member can be realized with a simple configuration by using the coil spring, and the coil spring can be easily screwed without using a tool. Further, when the fixed object is removed from the object by loosening the screw shaft member, the coil spring can be prevented from unexpectedly jumping out and losing the coil spring. In addition, since the coil spring is formed in a circular shape (conical shape), it is easy to handle when attached to the screw shaft member, and is stable when placed between the fixed object and the object. And the weight is light, and even if the head of the screw shaft member is operated, it does not easily fall off from the shaft portion of the screw shaft member. As a result, the fixed object and the screw shaft member are separated. It can prevent more reliably.

  The fixing device according to claim 4 is configured such that a lower side portion of an outer frame of a gaming machine (for example, a pachinko gaming machine) is provided in a gaming machine installation space formed between an upper island frame and a lower island frame provided on the gaming island base. It shall be fixed by a fixed object. Thus, in this fixing device, the shaft portion of the screw shaft member is sequentially inserted from above into the insertion hole of the fixed object and the insertion hole of the coil spring, and the head portion of the screw shaft member is operated to screw the screw shaft member. Thus, the fixed object is brought into contact with the lower side portion of the outer frame of the gaming machine, and the outer frame is pressed to the lower island frame side below. That is, by screwing the screw shaft member from above against the urging force of the coil spring, the fixed object comes into contact with the lower side of the outer frame and presses the outer frame downward, so that the lower side of the outer frame Is fixed between the fixed object and the lower island frame so that the lower side of the outer frame of the gaming machine is fixed in the gaming machine installation space.

  Accordingly, in the fixing device of the present invention configured as described above, in a state where the screwing of the screw shaft member is weakened, the fixed object is moved away from the lower island frame (upward) by the biasing force of the coil spring. Therefore, it is possible to prevent the fixed object from falling downward due to its own weight. As a result, when inserting the gaming machine (outer frame) into the gaming machine installation space, insertion of the gaming machine (outer frame) into the gaming machine installation space The fixed object can be moved to a position where it is not obstructed, and the game machine (outer frame) can be easily fixed.

It shall be fixed by a fixed object. Thus, in this fixing device, the shaft portion of the screw shaft member is sequentially inserted from below into the insertion hole of the fixed object and the insertion hole of the coil spring, and the head portion of the screw shaft member is operated to screw the screw shaft member. As a result, the fixed object is brought into contact with the upper side of the outer frame of the gaming machine, and the outer frame is pressed toward the upper upper island frame. That is, by screwing the screw shaft member from below against the urging force of the coil spring, the fixed object comes into contact with the upper side of the outer frame and presses the outer frame upward, so that the upper side of the outer frame Is fixed between the fixed object and the upper island frame so that the upper side of the outer frame of the gaming machine is fixed in the gaming machine installation space.

  Therefore, in the fixing device of the present invention configured as described above, since the fixed object and the screw shaft member are firmly fixed by the coil spring, an unfamiliar operator operates the head of the screw shaft member from below. When the screw shaft member is loosened and the fixed object is removed, the screw shaft member falls due to its own weight, or the coil spring unexpectedly jumps out, and the screw shaft member and the coil spring are separated from the fixed object. As a result, the screw shaft member and the coil spring are mixed into the game island stand, and various devices constituting the game island stand do not function normally (for example, the screw shaft member and the coil). The problem that the spring may cause clogging of the ball or damage the device due to damage may be avoided.

Note that the conical coil spring 149 has a coiled diameter formed by gradually reducing the coil winding diameter from the upper end to the lower end, and the coil winding diameter of the lower end portion 149a is the male winding bolt 145. The screw diameter of the screw portion 173 is set almost the same. The coil spring 146 is disposed in the mounting member 142 so that one end of the coil spring 146 contacts the rear wall surface 159 of the mounting member 142 and the other end contacts the rear wall surface 170 of the screw receiving member 144. The receiving member 144 is always urged forward.

  Next, the slide adjusting mechanism 180 that fixes the upper gaming machine fixing device 140 and the prize ball supply device 14 to the upper island frame 4 so as to be slidable is described. In the following description, for the sake of convenience, only the slide adjustment mechanism 180 that fixes the upper gaming machine fixing device 140 so as to be slidable will be described. 6A and 6B, the slide adjusting mechanism 180 includes a slide base 181 screwed to the upper island frame 4 and a mounting flange portion 152 of the mounting base 141 constituting the upper gaming machine fixing device 140. A spacer 183 and a slide plate 184 attached and fixed to each other by a butterfly bolt 182, and a butterfly bolt 185 and a washer 186 attached to the slide plate 184.

  The slide base 181 is formed in an “L” shape in cross section, and its entire length is substantially the same as the lateral width of the outer frame 9. A plurality of mounting holes 188 for screwing are formed in the upper wall piece 187 of the slide base 181 fixed in surface contact with the upper end surface of the upper island frame 4, and spacers are provided in the side wall piece 189 of the slide base 181. A slide groove 191 that engages with 183 and the slide plate 184 is provided over the entire length of the slide base 181 by a pair of upper and lower groove forming walls 190.

  The spacer 183 is formed of a substantially square flat plate, and a screw hole 192 to be screwed with the butterfly bolt 182 is formed on the flat plate surface. On the other hand, the slide plate 184 is a horizontally rectangular flat plate that is slightly larger than the spacer 183, and screw holes 193 and 194 that engage with the butterfly bolts 182 and 185 are formed in the flat plate surface along the longitudinal direction. It is installed. The spacer 183 and the slide plate 184 are attached and fixed to the attachment flange portion 152 (attachment hole 151) of the attachment base 141 with butterfly bolts 182 through screw holes 192 and 193, respectively. Further, the lateral dimension of the spacer 183 is set to be substantially the same as the lateral width of the mounting flange portion 152, and the lateral dimension of the slide plate 184 is set to be longer than the lateral width of the mounting flange portion 152. For this reason, the spacer 183 is fixed to the mounting base 141 without protruding from the left and right sides of the mounting flange portion 152. On the other hand, the slide plate 184 is in a state where the spacer 183 is sandwiched between the slide plate 184 and one end thereof (the side where the screw hole 194 is formed) projects from one end of the attachment flange portion 152. It is fixed in the state. And the one end side part (part in which the screw hole 194 was pierced) of the slide board 184 protruded from the attachment flange part 152 comprises the attachment part 195 of the butterfly bolt 185 and the washer 186.

  Thus, the slide base 181 constituting the slide adjusting mechanism 180 is attached to the upper island frame 4 by screws through the mounting holes 188 for each pachinko gaming machine installed on the pachinko island base 1. Next, the spacer 183 and the slide plate of the slide adjustment mechanism 180 in which the mounting base 141 of the upper game machine fixing device 140 is fixed by the butterfly bolt 182 in the slide groove 191 of the slide base 181 fixed to the upper island frame 4 in this way. By sliding and inserting 184 from the side, the upper game machine fixing device 140 is slidably attached to the slide base 181 fixed to the upper island frame 4. Then, the upper gaming machine fixing device 140 is slid to a position where the upper side of the outer frame 9 constituting the pachinko gaming machine is fixed, and the butterfly bolt 185 attached to the mounting portion 195 of the slide plate 184 is tightened in this state. As a result, the groove forming wall 190 of the slide base 181 that forms the slide groove 191 is sandwiched between the slide plate 184 and the washer 186. As a result, the outer frame 9 is fixed by the upper gaming machine fixing device 140. It is fixed at a desired fixing position.

  Next, a procedure for fixing the pachinko gaming machine (outer frame 9) in the gaming machine installation space 10 so that the inclination angle can be adjusted by the upper gaming machine fixing device 140 described above will be described. In assembling the upper gaming machine fixing device 140, the attachment member 142 is attached to the attachment base 141 in one of two attachment states. That is, the fixing bolt 147 screwed to the mounting flange portion 162 of the mounting member 142 is screwed into the rear screw hole 154 formed in the base plate portion 150 of the mounting base 141, and the mounting member 142 is attached to the mounting base 141. When attached and fixed, as shown in FIG. 6A, the attachment member 142 is attached to the rear side of the attachment base 141, so that the attachment base 141 is screwed to the upper island frame 4. A pressing and fixing member 143 is disposed on the rear side. For this reason, when the depth of the outer frame 9 is set large, in other words, when the rear end surface of the outer frame 9 is installed in the rear, the press fixing member 143 is moved in the state shown in FIG. By arranging on the rear side, fixing work corresponding to the outer frame 9 having a large depth can be performed.

  On the other hand, the fixing bolt 147 screwed to the mounting flange portion 162 of the mounting member 142 is screwed into the front screw hole 153 formed in the base plate portion 150 of the mounting base 141, and the mounting member 142 is mounted to the mounting base 141. In the case of fixing, the attachment member 142 is attached to the front side with respect to the attachment base 141, so that the pressing and fixing member 143 is arranged on the front side with respect to the upper island frame 4 to which the attachment base 141 is screwed. For this reason, when the depth of the outer frame 9 is set to be small, in other words, when the rear end surface of the outer frame 9 is installed without entering the rear side, the depth of the outer frame 9 can be reduced by arranging the pressing fixing member 143 on the front side. The fixing work corresponding to the small outer frame 9 can be performed.

  Then, with respect to the upper gaming machine fixing device 140 described above, the gaming machine installation space with the upper surface of the upper side of the outer frame 9 in contact with the mounting flange portion 161 of the mounting member 142 as shown in FIG. When the outer frame 9 is inserted into the outer frame 9, as shown in FIG. 8 (B), the inclination angle of the outer frame 9 is then adjusted using the adjustment tool C for adjusting the inclination angle at the upper side of the outer frame 9. Adjust. Specifically, in a state where the pressing surface portion C1 of the adjustment tool C is in contact with the front surface of the upper side of the outer frame 9, the adjustment tool C is moved to a position where the adjustment recess C2 of the adjustment tool C contacts the front end surface of the upper island frame 4. Is adjusted to adjust the front / rear position of the upper side portion of the outer frame 9 relative to the upper island frame 4, thereby adjusting the inclination angle of the upper side portion of the outer frame 9. That is, the adjustment tool C is provided in advance with a plurality of types with different depth dimensions of the adjustment recess C2 so that the pachinko gaming machine can be set to a desired inclination angle. However, in this case, assuming that the lower side portion of the outer frame 9 is fixed, the inclination angle is adjusted by adjusting the position of the upper side portion of the outer frame 9 in the front-rear direction. At this time, the pressing fixing member 143 is in a state in which the pressing of the outer frame 9 by the pressing claw portion 168 is released, and in other words, the moving direction of the mounting bolt 145 with respect to the insertion hole 160 of the mounting member 142, in other words, the gaming machine installation The pachinko gaming machine (outer frame 9) installed in the space 10 can be slid along the front-rear direction. Therefore, when the outer frame 9 is pushed rearward by the adjustment tool C, the pressing fixing member 143 has the support portion 164a which is the front end portion of the side wall surface 164 in contact with the rear end surface of the upper side of the outer frame 9. In this state, it slides backward against the urging force of the coil spring 146.

  Thereafter, as shown in FIG. 8C, the male threaded portion 173 of the mounting bolt 145 is screwed into the threaded hole 172 of the threaded receiving member 144 to resist gravity and the biasing force of the conical coil spring 149. Then, the pressing fixing member 143 is moved in the direction approaching the mounting member 142 (upward), and finally, the pressing claw portion 168 is pressed to the position where the upper lower surface is pushed upward while being inserted into the upper lower surface of the outer frame 9. By moving the fixing member 143, the upper side portion of the outer frame 9 is pinched and fixed between the pressing fixing member 143 (the pressing claw portion 168) and the contact flange portion 161 of the mounting member 142. At this time, if necessary, the pressing bolt 148 is screwed into the screw hole 165a of the pressing fixing member 143 (see FIG. 5), so that the lower surface of the upper side of the outer frame 9 is pressed even at the tip of the pressing bolt 148. Thereby, even when the outer frame 9 is formed of a hard material such as hard plastic and the outer frame 9 having high hardness is fixed by the upper game machine fixing device 140, the pressing claw portion 168 is pushed back by the hard outer frame 9 Warping) can be suppressed, and the outer frame 9 can be securely fixed by a strong pushing force. However, if the outer frame 9 is made of a relatively hard material such as plastic, the screw 9 is screwed into the screw hole 165a of the pressing fixing member 143 in place of the pressing bolt 148 to fix the screw. Thus, the outer frame 9 can be fixed more firmly.

  In addition, when pressing and fixing the outer frame 9 from below by the pressing claw portion 168 of the pressing fixing member 143, a strong reaction force is received from the lower surface of the upper side of the outer frame 9 through the pressing claw portion 168. In the pressing state by the pressing claw portion 168, the contact portion 166a of the rear wall surface 166 of the pressing fixing member 143 comes into contact with the upper wall surface 157 of the mounting member 142, and the conical coil spring 149 contracts. The urging force of the conical coil spring 149 acts in a direction (downward) in which the pressing and fixing member 143 is moved away from the mounting member 142. Therefore, a strong reaction force applied to the pressing claw portion 168 that is one end portion of the pressing and fixing member 143 is received by the upper wall surface 157 of the mounting member 142 that contacts the contact portion 166a that is the other end portion of the pressing and fixing member 143. At the same time, since it is received by the conical coil spring 149, it is possible to avoid a situation in which the pressing and fixing member 143 is deformed by receiving a reaction force from the outer frame 9.

  Further, the upper gaming machine fixing device 140 is configured to include a coil spring 146 that is disposed in the attachment member 142 and biases the screw receiving member 144 forward. For this reason, the pressing and fixing member 143 attached integrally with the screw receiving member 144 via the mounting bolt 145 is also urged forward by the elastic force of the coil spring 146. Accordingly, when the pachinko gaming machine (outer frame 9) is fixed, the support portion 164a of the pressing fixing member 143 that supports the rear end surface of the upper side portion of the outer frame 9 always presses the upper side portion of the outer frame 9 forward. In other words, it automatically moves in a direction that eliminates the gap with the rear end surface of the upper side of the outer frame 9. As a result, the pachinko gaming machine (outside) by the upper gaming machine fixing device 140 in a state in which the outer frame 9 is securely supported by bringing the support portion 164a of the pressing fixing member 143 into close contact with the rear end surface of the upper side portion of the outer frame 9. The frame 9) can be fixed.

  Furthermore, by adopting a configuration in which the pressing and fixing member 143 is biased forward by the elastic force of the coil spring 146, the foremost position where the pressing and fixing member 143 can always slide and move in a state where the pachinko gaming machine is not fixed. Can be moved to. For this reason, the complicated operation | work which returns the press fixing member 143 from a back position to the front for every attachment and removal operation | work of the pachinko game machine to the game machine installation space 10 becomes unnecessary. Moreover, even when the depth of the pachinko gaming machine (outer frame 9) to be installed is different from that before replacement, the support portion 164a of the pressing and fixing member 143 always presses the upper side of the outer frame 9 forward. Direction, in other words, automatically moves in a direction that eliminates the gap with the rear end surface of the upper side of the outer frame 9, so that the pressing fixing member 143 is moved and adjusted in the front-rear direction according to the depth of the outer frame 9. Therefore, it is possible to easily fix the outer frame 9. In the case of a worker who is unfamiliar with the fixing operation of the pachinko gaming machine, a gap is generated between the support portion 164a of the pressing fixing member 143 and the rear end surface of the upper side portion of the outer frame 9, and the support state of the outer frame 9 The pachinko gaming machine may be fixed while being unstable, but with the configuration described above, the pachinko gaming machine can be fixed in a reliable support state regardless of the skill level of the fixing work. .

  Further, according to the configuration described above, when the support portion 164a of the pressing and fixing member 143 moves in the front-rear direction due to the elastic force of the coil spring 146, the pressing claw portion 168 of the pressing and fixing member 143 is also integrally moved back and forth. It is designed to move in the direction. Therefore, the upper gaming machine fixing device 140 presses a predetermined front position from the rear end surface of the upper side portion of the outer frame 9 even when the pachinko gaming machine (outer frame 9) having different depths is fixed. As a result, the depth of the outer frame 9 is set to be extremely short, or the position of the support portion 164a needs to be moved considerably forward by moving the outer frame 9 extremely forward as an adjustment of the tilt angle. However, it is possible to avoid the fixing position of the outer frame 9 by the pressing claw portion 168 from being the rear end, and the outer frame 9 can be reliably fixed.

  By the way, when the pachinko gaming machine before replacement installed in the gaming machine installation space 10 is removed by the upper gaming machine fixing device 140 by replacement of the pachinko gaming machine, it is originally pressed in the state shown in FIG. As shown in FIG. 9B, the pressing fixing member 143 is not detached from the upper gaming machine fixing device 140 (attaching member 142) by gradually rotating while visually observing the disengagement of the attaching bolt 145 from the fixing member 143. Thus, an unfamiliar worker rotates the mounting bolt 145 (operation unit 174) at once without adjusting with an electric tool or the like. As a result, as shown in FIG. The male threaded portion 173 of 145 is disengaged from the screw hole 172 of the screw receiving member 144, and therefore, the pressing fixing member 143 is detached from the upper game machine fixing device 140 (attachment member 142). It may be put away. However, in the upper gaming machine fixing device 140 of the present embodiment, the conical coil spring 149 is formed in the shape of a trough by gradually reducing the coil winding diameter from the upper end to the lower end, and the lower end portion 149a. The coil winding diameter is set to be substantially the same as the screw diameter of the male screw portion 173 of the mounting bolt 145. Therefore, the conical coil spring 149 is interposed between the press fixing member 143 and the mounting member 142 in a state where the lower end portion 149a is locked to the male screw portion 173 so that the lower end portion 149a contacts the upper wall surface 165 of the press fixing member 143. Will be placed.

  That is, as shown in FIG. 9C, the upper gaming machine fixing device 140 of the present embodiment includes an operation portion 174 of a mounting bolt 145 formed larger than the mounting hole 167 of the pressing fixing member 143 and a conical coil spring 149. Thus, the pressing and fixing member 143, the mounting bolt 145, and the conical coil spring 149 are assembled and integrally formed with the pressing and fixing member 143 sandwiched therebetween. Therefore, even if an unfamiliar operator rotates the mounting bolt 145 at a stroke to disengage the pressing fixing member 143 from the upper gaming machine fixing device 140 (mounting member 142), the mounting bolt 145 falls off the pressing fixing member 143 by its own weight. Even if the conical coil spring 149 disengages from the mounting bolt 145 and unexpectedly jumps and separates, that is, even if the pressing fixing member 143 is detached from the upper game machine fixing device 140, the mounting bolt 145 In addition, the conical coil spring 149 is prevented from being separated from the pressing and fixing member 143. Accordingly, when the pachinko gaming machine is replaced, the mounting bolt 145 and the conical coil spring 149 are separated from the pressing and fixing member 143 and fallen and stored in a ball storage tank or the like of the pachinko island 1. The mounting bolt 145 and the conical coil spring 149 can be prevented from being lost. As a result, the lost mounting bolt 145 and the conical coil spring 149 in the pachinko island base 1 cause It is possible to avoid troubles such as clogging and failure of the circulation device.

  Further, the conical coil spring 149 can be easily attached to or detached from the male screw portion 173 of the mounting bolt 145 without using a tool, and can be attached to or detached from the mounting bolt 145, and the conical shape is conical. Therefore, the operation at the time of attaching to the attachment bolt 145 is easy to perform, and the stability when arranged between the upper wall surface 165 of the pressing and fixing member 143 and the upper wall surface 157 of the attachment member 142 is very good. In addition, the conical coil spring 149 is light in weight, and the lower end portion 149a is locked to the male screw portion 173 without dropping from the male screw portion 173 even when the operation portion 174 of the mounting bolt 145 is rotated. Can be maintained.

  Next, the configuration of the lower gaming machine fixing device 300 will be described with reference to FIGS.

Further, by assembling the lower gaming machine fixing device 300 as described above, the conical coil spring 307 is disposed between the upper wall surface 315 of the pressing fixing member 303 and the upper wall surface 311 of the attachment member 302. The conical coil spring 307 always urges the pressing and fixing member 303 so that the upper wall surface 315 contacts the operation portion 324 of the mounting bolt 305. The conical coil spring 307 is formed in a circular shape by gradually reducing the coil winding diameter from the lower end to the upper end, and the coil winding diameter of the upper end portion 307a is the male winding bolt 305. The screw diameter of the screw portion 323 is set to be substantially the same. Further, the coil spring 309 disposed between the rear wall surface 320b of the screw receiving member 304 and the rear wall surface 312b of the attachment member 302 always urges the screw receiving member 304 forward as described above. However, the pressing and fixing member 303 connected by the screw receiving member 304 and the mounting bolt 305 is always urged forward.

  Thus, when the lower side of the outer frame 9 is fixed to the gaming machine installation space 10 by the lower gaming machine fixing device 300 described above, the outer frame 9 is first installed on the gaming machine as shown in FIG. Insert from the front of the space 10. At this time, the male screw portion 323 of the mounting bolt 305 is loosened with respect to the screw hole 322 of the screw receiving member 304, so that the pressing and fixing member 303 moves away from the mounting member 302 by the urging force of the conical coil spring 307 ( Moved upward). Thereby, even when the screwing of the mounting bolt 305 with respect to the screw receiving member 304 is weakened, it is possible to avoid the pressing claw portion 318 of the pressing fixing member 303 from dropping downward due to its own weight. Therefore, even when the outer frame 9 is inserted into the gaming machine installation space 10 from the front, the pressing claw portion 318 may be moved to a position that does not hinder the insertion of the outer frame 9 into the gaming machine installation space 10. The outer frame 9 can be easily fixed.

  At this time, the pressing fixing member 303 is loosened by screwing the mounting bolt 305 (male threaded portion 323) into the screw hole 322, and the pressing claw portion 318 is in contact with and pressed against the outer frame 9. Since there is no state, the moving direction of the mounting bolt 305 with respect to the insertion hole 311a of the mounting member 302, in other words, the sliding movement along the front-rear direction of the pachinko gaming machine (outer frame 9) installed in the gaming machine installation space 10 Is possible. Then, as shown in FIGS. 11B and 11C, the front and rear positions of the lower side of the outer frame 9 relative to the lower island frame 5 are adjusted by moving the lower side of the outer frame 9 in the front-rear direction on the support plate 7. This adjusts the inclination angle of the pachinko gaming machine at the lower side of the outer frame 9. However, in this case, assuming that the upper side portion of the outer frame 9 is fixed, the inclination angle is adjusted by adjusting the position of the lower side portion of the outer frame 9 in the front-rear direction. In addition, when the lower side portion of the outer frame 9 is moved in the front-rear direction, the pressing fixing member 303 has the support portion 314a that is the front end portion of the side wall surface 314 abutted with the rear end surface of the lower side of the outer frame 9. In this state, it slides backward against the ineffective force of the coil spring 309 or slides forward.

  Thereafter, as shown in FIG. 11 (D), by adjusting the front and rear position of the lower side of the outer frame 9, the adjustment of the inclination angle of the pachinko gaming machine is completed, and the male threaded portion 323 of the mounting bolt 305 is screwed together. By screwing into the screw hole 322 of the receiving member 304, the pressing fixing member 303 is moved in the direction approaching the mounting member 302 (downward) against the urging force of the conical coil spring 307, and finally the pressing claw The pressing and fixing member 303 is moved while the portion 318 is inserted into the upper surface of the lower side of the outer frame 9. Accordingly, the lower side portion of the outer frame 9 is sandwiched and fixed between the pressing fixing member 303 (the pressing claw portion 318) and the support plate 7. Further, at this time, if necessary, by screwing a pressure bolt (not shown) into the screw hole 319 of the pressure fixing member 303, the upper surface of the lower side of the outer frame 9 can be supplementarily pressed even at the tip of the pressure bolt. . Thereby, even when the outer frame 9 is formed of a hard material such as hard plastic and the outer frame 9 having high hardness is fixed by the lower gaming machine fixing device 300, the pressing claw portion 318 is pushed back by the hard outer frame 9 ( Can be suppressed, and the outer frame 9 can be reliably fixed with a strong pushing force. However, when the outer frame 9 is made of a relatively hard material such as plastic, the screw is replaced by screwing the screw into the screw hole 319 of the pressing fixing member 303 instead of the pressing bolt. Thus, the outer frame 9 can be fixed more firmly.

  When the outer frame 9 is pressed and fixed from above by the pressing claw portion 318 of the pressing fixing member 303, a strong reaction force is received from the upper surface of the lower side of the outer frame 9 through the pressing claw portion 318. In the pressing state by the pressing claw portion 318, the abutting portion 316a of the rear wall surface 316 of the pressing fixing member 303 comes into contact with the upper wall surface 311 of the mounting member 302, and the conical coil spring 307 contracts. The urging force of the conical coil spring 307 acts in a direction (upward direction) away from the pressing and fixing member 303 from the mounting member 302. Therefore, a strong reaction force applied to the pressing claw portion 318 that is one end portion of the pressing and fixing member 303 is received by the upper wall surface 311 of the attachment member 302 that contacts the contact portion 316 a that is the other end portion of the pressing and fixing member 303. At the same time, since it is received by the conical coil spring 307, it is possible to avoid a situation in which the pressing and fixing member 303 is deformed by receiving a reaction force from the outer frame 9.

  The lower gaming machine fixing device 300 also includes a coil spring 309 that is disposed in the attachment member 302 and biases the screw receiving member 304 forward, similarly to the upper gaming machine fixing device 140 described above. It has become. Therefore, the pressing and fixing member 303 that is integrally attached to the screw receiving member 304 via the mounting bolt 305 is also urged forward by the elastic force of the coil spring 309. Therefore, when fixing the pachinko gaming machine (outer frame 9), the support portion 314a of the pressing fixing member 303 that supports the rear end surface of the lower side portion of the outer frame 9 always presses the lower side portion of the outer frame 9 forward. In other words, it automatically moves in a direction that eliminates the gap with the rear end surface of the lower side of the outer frame 9. As a result, the pachinko gaming machine by the lower gaming machine fixing device 300 in a state in which the outer frame 9 is securely supported by bringing the support portion 314a of the pressing and fixing member 303 into close contact with the rear end surface of the lower side portion of the outer frame 9 ( The outer frame 9) can be fixed.

  Furthermore, by adopting a configuration in which the pressing and fixing member 303 is biased forward by the elastic force of the coil spring 309, the foremost position where the pressing and fixing member 303 can always be slid in a state where the pachinko gaming machine is not fixed. Can be moved to. For this reason, the complicated operation | work which returns the press fixing member 303 to the front from a back position for every attachment and removal operation | work of the pachinko game machine to the game machine installation space 10 becomes unnecessary. Moreover, even when the depth of the pachinko gaming machine (outer frame 9) to be installed is different from that before replacement, the support portion 314a of the pressing and fixing member 303 always presses the lower side of the outer frame 9 forward. Direction, in other words, it automatically moves in a direction that eliminates the gap with the rear end surface of the lower side of the outer frame 9, so that the pressing and fixing member 303 is moved and adjusted in the front-rear direction according to the depth of the outer frame 9. Therefore, it is possible to easily fix the outer frame 9. In the case of a worker who is unfamiliar with the fixing operation of the pachinko gaming machine, a gap is generated between the support portion 314a of the pressing and fixing member 303 and the rear end surface of the lower side portion of the outer frame 9, and the support state of the outer frame 9 The pachinko gaming machine may be fixed while being unstable, but with the configuration described above, the pachinko gaming machine can be fixed in a reliable support state regardless of the skill level of the fixing work. .

  Further, according to the configuration described above, when the support portion 314a of the pressing and fixing member 303 moves in the front-rear direction due to the elastic force of the coil spring 309, the pressing claw portion 318 of the pressing and fixing member 303 is also integrated with the front and rear. It is designed to move in the direction. For this reason, the lower gaming machine fixing device 300 presses a predetermined front position from the rear end surface of the lower side portion of the outer frame 9 even when the pachinko gaming machine (outer frame 9) having different depths is fixed. . As a result, the depth of the outer frame 9 is set to be extremely short, or the position of the support portion 314a needs to be moved considerably forward by moving the outer frame 9 extremely forward as an adjustment of the tilt angle. However, it can be avoided that the fixing position of the outer frame 9 by the pressing claw portion 318 becomes the rear end, and the outer frame 9 can be fixed securely.

  By the way, when the pachinko gaming machine before replacement installed in the gaming machine installation space 10 by the lower gaming machine fixing device 300 is removed by replacement of the pachinko gaming machine, originally, in the state shown in FIG. As shown in FIG. 12B, the fixing bolt 303 is rotated from the lower gaming machine fixing device 300 (attaching member 302) by gradually rotating the mounting bolt 305 from the pressing fixing member 303 while visually observing. A worker who is unfamiliar with the place that should be used so as not to be detached can rotate the mounting bolt 305 (operation unit 324) at once without adjusting with an electric tool or the like. As a result, as shown in FIG. The male threaded portion 323 of the mounting bolt 305 is disengaged from the screw hole 322 of the screw receiving member 304, so that the pressing fixing member 303 is removed from the lower gaming machine fixing device 300 (the mounting member 302). It may sometimes be out. However, in the lower gaming machine fixing device 300 according to the present embodiment, the conical coil spring 307 is formed in the shape of a trough by gradually reducing the coil winding diameter from the lower end to the upper end. The coil winding diameter of 307a is set to be substantially the same as the screw diameter of the male screw portion 323 of the mounting bolt 305. Therefore, the conical coil spring 307 is interposed between the press fixing member 303 and the mounting member 302 in a state where the upper end portion 307a is locked to the male screw portion 323 so that the upper end portion 307a contacts the upper wall surface 315 of the press fixing member 303. Will be placed.

  That is, as shown in FIG. 12C, the lower gaming machine fixing device 300 of the present embodiment includes an operation portion 324 of the mounting bolt 305 formed larger than the mounting hole 317 of the pressing fixing member 303 and a conical coil spring. The pressing and fixing member 303, the mounting bolt 305, and the conical coil spring 307 are integrally formed in a state where the pressing and fixing member 303 is sandwiched between the pressing and fixing member 303. Therefore, even if an unfamiliar operator rotates the mounting bolt 305 at a stroke to disengage the pressing fixing member 303 from the lower gaming machine fixing device 300 (the mounting member 302), the mounting bolt 305 falls off the pressing fixing member 303 and is separated. Or the conical coil spring 307 comes off from the mounting bolt 305 and unexpectedly jumps and separates, that is, even if the pressing fixing member 303 is detached from the lower gaming machine fixing device 300, the mounting bolt 305 and The conical coil spring 307 is prevented from separating from the pressing and fixing member 303. Accordingly, when the pachinko gaming machine is replaced, the mounting bolt 305 and the conical coil spring 307 are separated from the pressing and fixing member 303 and fallen and stored in a ball storage tank or the like of the pachinko island 1. The mounting bolt 305 and the conical coil spring 307 can be prevented from being lost. As a result, in the pachinko island 1, the lost mounting bolt 305 and the conical coil spring 307 cause the ball It is possible to avoid troubles such as clogging and failure of the circulation device.

  Furthermore, the conical coil spring 307 can be easily attached to or detached from the mounting bolt 305 by attaching / detaching it to / from the male screw portion 323 of the mounting bolt 305 without using a tool, and has a conical shape. Therefore, the operation at the time of attaching to the attachment bolt 305 is easy to perform, and the stability when arranged between the upper wall surface 315 of the pressing and fixing member 303 and the upper wall surface 311 of the attachment member 302 is very good. In addition, the conical coil spring 307 is light in weight, and the upper end portion 307a is locked to the male screw portion 323 without dropping from the male screw portion 323 even when the operation portion 324 of the mounting bolt 305 is rotated. Can be maintained.

As is apparent from the above description, according to the configuration of the pachinko gaming machine fixing device (upper gaming machine fixing device 140, lower gaming machine fixing device 300) according to this embodiment, the following effects are obtained. Play.
(1) When the pachinko gaming machine is replaced, even if the depth of the pachinko gaming machine (outer frame 9) to be replaced is different from that before replacement, the pressing and fixing member 143 depends on the depth of the outer frame 9. , 303 need not be moved and adjusted in the front-rear direction, and only the degree of insertion of the outer frame 9 into the gaming machine installation space 10 needs to be adjusted. As a result, the pachinko gaming machine (outer frame 9) can be easily fixed. It is possible to perform the replacement work of the pachinko gaming machine smoothly.
(2) When the pachinko gaming machine is fixed in the gaming machine installation space 10, the pressing claw portions 168 and 318 of the pressing fixing members 143 and 303 are rear end surfaces of the outer frame 9 regardless of the depth of the outer frame 9. The predetermined front position can be pressed from the front, and as a result, the pachinko gaming machine (outer frame 9) can be reliably fixed to the gaming machine installation space 10.
(3) To adjust the inclination angle of the pachinko gaming machine, the pressing and fixing members 143 and 303 are slid in parallel with the longitudinal direction of the pachinko gaming machine (outer frame 9) to adjust the positions of the support portions 164a and 314a. After that, it is only necessary to screw in the mounting bolts 145 and 305. As a result, the inclination angle of the pachinko gaming machine can be easily adjusted.
(4) Even if the pachinko gaming machine (outer frame 9) is fixed and the strong reaction force is received from the outer frame 9 via the pressing claw portions 168 and 318 of the pressing and fixing members 143 and 303, the pressing and fixing member 143 303, the abutting portions 166a and 316a of the rear wall surfaces 166 and 316 abut on the upper wall surfaces 157 and 311 of the mounting members 142 and 302, and the conical coil springs 149 and 307 contract, so that the pressing claw portion 168 318 is received by the upper wall surfaces 157 and 311 of the mounting members 142 and 302 and by the conical coil springs 149 and 307, so that the pressing and fixing members 143 and 303 are removed from the outer frame 9. It is possible to avoid the situation of deformation due to the reaction force.
(5) The conical coil springs 149 and 307 have coil winding diameters at one end portions (lower end portion 149a and upper end portion 307a) set to be substantially the same as the screw diameters of the male screw portions 173 and 323 of the mounting bolts 145 and 305 The pressing and fixing member 143 is engaged with the male screw portions 173 and 323 so that the one end portions (the lower end portion 149a and the upper end portion 307a) are in contact with the upper wall surfaces 165 and 315 of the pressing and fixing members 143 and 303. , 303 and the mounting members 142, 302, that is, the pressing and fixing members 143, 303, the mounting bolts 145, 305, and the conical coil springs 149, 307 are integrally assembled. Therefore, when replacing pachinko machines or maintenance work of the gaming machine fixing devices 140 and 300, an unfamiliar worker can attach the mounting bolt 145. Even if the pressure fixing members 143 and 303 are detached from the game machine fixing devices 140 and 300 by rotating the 305 at a stroke, the mounting bolts 145 and 305 and the conical coil springs 149 and 307 are separated from the pressure fixing members 143 and 303. As a result, the mounting bolts 145 and 305 and the conical coil springs 149 and 307 are mixed into the pachinko island base 1, and various devices constituting the pachinko island base 1 do not function normally. Can be avoided. In particular, in the upper game machine fixing device 140, there is a high possibility that the mounting bolt 145 will fall out of the pressing and fixing member 143 due to its own weight. Therefore, the separation of the mounting bolt 145 from the pressing and fixing member 143 is performed with the conical coil spring 149. Therefore, it can be surely prevented.
(6) The conical coil spring 307 moves the pressing and fixing member 303 in the direction away from the mounting member 302 (upward) by its biasing force in a state where the screwing of the mounting bolt 305 is weakened. As a result, when the pachinko gaming machine (outer frame 9) is inserted into the gaming machine installation space 10 from the front side, the pachinko gaming machine (outer frame 9) can be avoided. The pressing claw portion 318 can be moved to a position that does not hinder the insertion into the gaming machine installation space 10, and the fixing operation of the pachinko gaming machine (outer frame 9) can be facilitated.
