  However, the pachinko gaming machine jig of Patent Document 1 facilitates the posture and orientation of the frame body (pachinko gaming machine) such as turning it over, standing up, and laying down when removing or assembling parts from the pachinko gaming machine. Although the pachinko gaming machine is configured by the frame body and the game board unit as described above, when assembling or disassembling the game board unit alone in a state of being detached from the frame body. Needless to say, this pachinko machine jig cannot be used.

  Therefore, development of a jig that can improve the efficiency of the game board unit, particularly when assembling, is demanded. Specifically, the game board unit has an accessory device that produces a game by decoration or predetermined movement or light emission inside a box-like board back cover on the back side of a game board such as veneer plywood or acrylic board. The assembled back panel unit is fixed. And in recent game board units (pachinko machines), in order to improve the interest of the game, this accessory device is diversified and complicated, and a large number of one board unit (board cover) is provided. There is a tendency, and when assembling the accessory device to the back cover, complicated work is required, which may cause an increase in manufacturing cost.

  An object of the present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an assembly jig for a back unit that can improve the efficiency of the assembly of the back unit in a gaming machine.

In order to solve the above problems, the assembly jig of the back panel unit of the present invention is:
Assemble the back unit with a back cover fixed on the back side opposite to the front side of the game board that forms the game area, with a decoration or an accessory device that produces a game by predetermined movement or light emission. Assembly jig for
The board back cover has a box-like form, and is provided with an assembly part in which an opening is formed on the front side fixed to the game board and an accessory device is assembled inside,
A main body having a plate-like shape that is detachably fixed to the front side of the back cover directly or indirectly through another member and can cover part or all of the opening, and the main body A shape predetermined on the back side of the main body so as to coincide with or face the opening of the back cover when it is fixed to the front side of the back cover, or to enter inside from the opening A lid-like member having a raised portion that rises,
When the main body is fixed to the front side of the back cover in a state in which the accessory device is disposed in the assembly part of the back cover, the raised portion contacts at least the front side of the accessory device. It is characterized in that the separation from the assembling part is controlled and the fixing operation of the accessory device by the fastening member from the outside of the back cover is supported from the front side (inside).

  According to the present invention, as a jig for assembling the back unit, a main body part that is detachably fixed to the front side of the back cover and a raised part that rises in a predetermined shape on the back side of the main body part And a lid-like member. Then, a lid-like member is arranged so as to cover the opening of the back cover in a state where the accessory device is placed in the assembly part of the back cover, and the main body is fixed to the front side of the back cover. Then, since the raised portion abuts at least the front side of the accessory device and the separation from the assembly portion is restricted, the fixing operation of the accessory device by the fastening member from the outside of the back cover is performed on the front side (inside). It is possible to support from the standpoint, and it is possible to improve the efficiency of the assembly of the back unit in the gaming machine. In other words, by defining the raised shape of the raised part for each model, even when multiple diversified and complicated accessory devices are provided on the back cover, it can be handled without problems, and the back unit Assembly work can be done.

  In addition, when the main body is fixed to the front side of the back cover, the raised portion enters the inside from the opening of the back cover, and enters the position near the side of the accessory device in the front-rear direction. It can be set as the structure which controls the detachment | leave from the assembly | attachment part of the said accessory device.

  According to this, since the raised portion enters the position in the vicinity of the side of the accessory device with respect to the front-rear direction, the accessory device is more stably held by the assembly portion, such as turning over, standing up, and lying down. The posture and orientation of the back unit can be changed stably, and the efficiency of the assembly work of the back unit can be improved.

Moreover, in the case where the main body of the lid-like member is fixed to the front side of the back cover indirectly via an other member so as to be detachable,
As other members, provided with a frame-shaped base having a frame-shaped form in which through holes are formed in the thickness direction corresponding to the openings of the back cover,
The frame-shaped base has a first fixing means for removably fixing the back cover at a predetermined position on one surface side in the thickness direction, and a second fixing means for removably fixing a lid-like member on the other surface side. Have
When the back cover and the lid-like member are fixed to the frame-like base, the raised portion of the lid-like member is aligned with or opposed to the opening of the back cover through the through hole, or inward from the opening. It can be configured to enter.

  According to this, since the assembly jig is provided with the frame-like base having the first fixing means for fixing the back cover and the second fixing means for fixing the lid-like member, the back cover and the cover are provided. The fixing member can be stably fixed to the frame-like base by the respective fixing means, and the lid-like member can be easily and stably fixed to the back cover. In addition, since the frame-shaped base has a frame shape in which a through hole is formed corresponding to the opening of the back cover, the through hole is provided to the back cover fixed at a predetermined position on one surface side. The accessory device can be disposed on the assembly portion from the other surface side. Therefore, since the opening of the back cover is fixed to the frame-like base, the rigidity of the back cover is enhanced and the stability is improved, and the assembly of the accessory device to the back cover is further facilitated. As a result, assembly work can be carried out with high accuracy without variation. In addition, if the shape of the back cover is the same, the frame-like base can be used universally across multiple types of gaming machines, which can contribute to cost reduction.

In addition, on one surface side of the frame-shaped base, when the back cover is disposed at a predetermined position, positioning means is provided for restricting displacement and movement in the surface direction of the back cover,
The first fixing means may be configured to regulate the separation from one surface of the back cover arranged at a predetermined position by the positioning means.

  According to this, since the positioning means for restricting displacement and movement in the surface direction is provided on one surface side of the frame-like base, the accuracy and workability of the placement of the back cover are improved. Needless to say, since the peripheral portion forming the opening of the back cover is held (fixed) by the positioning means, the rigidity of the back cover can be further enhanced and the stability can be improved. As a result, it is possible to more easily assemble the accessory device to the back cover, and to perform assembly work with high accuracy without variation.

Further, the assembly jig includes a base having a plate-like form placed on a placement surface such as a work table or a work line;
A pair of shaft supports that rotatably support the frame-like base around a rotation axis extending in parallel with one surface;
A pair of fixed struts erected from the base with a pair of shaft support portions at the top, and
The frame-like base can be configured to be rotatable around the rotation axis above the base while the back cover and the lid-like member are fixed.

  According to this, since the frame-shaped base is rotatably supported by the shaft support portions of the pair of fixed support columns erected from the base, by rotating the frame-shaped base around the rotation axis, the back cover and The lid-like member can be easily fixed to one surface side and the other surface side of the frame-like base. And the fixing operation by the fastening member can be performed very easily from the outside of the back cover of the accessory device arranged in the assembly part.

The assembly jig is erected from an area on one side of the base with the rotation axis as a boundary when viewed from above, and is brought into contact with the lower surface of the frame-shaped base at a position spaced in the radial direction of the rotation axis. A first movable strut that is changeable between a first restriction state that contacts and restricts rotation in one direction of the frame-like base and a first retraction state that retreats from the rotation trajectory of the frame-like base;
A second restriction state that stands from the region on the other side of the base and is in contact with the lower surface of the frame-like base at a position spaced apart in the radial direction of the rotation axis, and restricts rotation in the other direction of the frame-like base; A second movable strut that is changeable between a second retracted state retracted from the rotation trajectory of the base,
When the first movable support column is in the first restricted state and the second movable support column is in the second restricted state, the frame-shaped base is held in a rotation restricted state in which rotation in one direction and the other direction is restricted simultaneously. It can be.

  According to this, with the rotation axis viewed from above as a boundary, the movable support columns are erected from the regions on both sides of the base, and the movable support columns are in contact with the lower surface of the frame-shaped base. Since the rotation restricted state is formed, the frame-like base can be held while being restricted in a stable state. And since it is not necessary to arrange structures or parts in the space above the frame-like base (opposite the base), the assembly work is not hindered and contributes to miniaturization. be able to.

  Further, the first and second movable struts of the assembling jig are erected at substantially the same height from the base, and the frame-shaped base is held parallel to the base in the rotation restricted state. It can be configured.

  That is, the first and second movable support columns are erected at a height corresponding to the height of the rotation axis. According to this, since the frame-like base is held in parallel with the base, the accessory device can be stably and easily disposed on the assembly portion of the back cover.

In addition, when the frame-shaped base that rotates in the other direction comes into contact with the first movable support column of the assembly jig in the first restricted state, the first movable support column changes to the first retracted state in response to the contact. Allow rotation in the other direction,
When the frame-shaped base that rotates in one direction comes into contact with the second movable support column in the second restricted state, the second movable support column changes to the second retracted state in response to the contact and rotates in the one direction. An acceptable configuration can be adopted.

  According to this, when the first movable column is in the first restricted state, the frame-shaped base is restricted from rotating in one direction while being allowed to rotate in the other direction, and the second movable column is in the second restricted state. In addition, while restricting the rotation of the frame-shaped base in the other direction and allowing the rotation in one direction, each movable support column functions as a one-way clutch with respect to the frame-shaped base. It is possible to shift from the rotation position (state) where the frame-like base is not in the rotation restricted state to the rotation restricted state without requiring any operation. Therefore, since the operability of the assembly jig is improved, it is possible to increase the efficiency of the assembly of the back unit in the gaming machine.

  Further, the first movable support column of the assembly jig can be laid down on the base, abuts the frame-shaped base at a position closer to the base than in the first restricted state, and extends in the other direction of the frame-shaped base. It can be set as the structure changeable to the 3rd control state which controls rotation.

  According to this, since the 1st movable support | pillar falls and forms a 3rd control state, it can control rotation of an other direction with respect to a frame-shaped base, Therefore A frame shape with an attitude | position different from a rotation control state The base can be stably held, and the efficiency of operations such as assembly or inspection of the back unit can be improved.

  Moreover, it can be set as the structure by which the wiring hook part which latches wiring is formed in the lid-shaped member of the jig | tool for an assembly.

  According to this, since the wiring provided in the back panel unit can be hooked and stopped on the wiring hook part, it avoids the hanging state where the wiring spreads and shakes, and when the frame-shaped base rotates, It is possible to effectively suppress or prevent the wiring from being caught on the movable support column and being damaged. When the wiring is hooked on the wiring hook portion of the lid-like member, the through-hole is closed by the lid-like member, so it is effective to hang the wiring from the outer peripheral side of the frame-like base. In this case, a notch may be formed on the outer peripheral edge of the frame-like base for positioning the wiring.

  Moreover, the lid-like member of the assembling jig can be configured such that part or all of the lid-like member is formed with transparency.

  According to this, since the lid-like member has transparency, even when the lid-like member is fixed to the back cover, it is possible to visually inspect the accessory device and efficiently inspect it. Furthermore, when it forms so that it may have transparency according to the through-hole (visible region) in a game board, it can test | inspect more efficiently.

  The outer protrusion 29a is preferably disposed in the opening 4a of the back cover 4 at a location where the mounting flange 4c described above is not formed. That is, the outer protrusion 29a has a predetermined height, and an area in contact (contact) with the peripheral wall 4d forming the opening 4a is increased and can be stably held. Note that, on the first main surface 21a of the frame-shaped base body 21, an inner protrusion 29b is formed along the inner peripheral edge of the opening 4a corresponding to the outer protrusion 29a. According to this, since the peripheral wall 4d forming the opening 4a of the back cover 4 is sandwiched between the outer protrusion 29a and the inner protrusion 29b, the positioning of the back cover 4 in the surface direction is more stable. Is possible.

  The first fixing means 123 is disposed on the top (lower side in the drawing) of the outer protrusion 29a. The first fixing means 123 includes a fastening portion 123 a that can be rotated or moved in a plane direction parallel to the frame-like base body 21. As a result, the fastening portion 123a faces or presses the rear side of the portion 4e bent from the peripheral wall portion 4d of the back cover 4 (in other words, the mounting flange portion 4c). The cover 4 is fixed by being separated from the first main surface 21a. The second fixing means 124 can also have the same configuration as the first fixing means 123, and includes a fastening portion 124a that can be rotated or linearly moved in a plane direction parallel to the frame-like base body 21. The lid member 10 (main body portion 11) can be fixed to the frame-like base main body 21 by the fastening portion 124a.

(Modification 2)
Next, a second modification of the assembly jig described above will be described. In the following description, portions different from the above-described embodiment will be mainly described, and overlapping portions will be denoted by the same reference numerals, and description thereof will be omitted or simplified. Specifically, the frame-shaped base 20 is provided as it is, and the description of the configuration of the frame-shaped base 20 is omitted or simplified.

  An assembly jig 6 </ b> A according to the second modification includes a lid-like member 10 and a jig body 20 </ b> A including a frame-like base 20. The jig body 20A has a base 30 in the form of a plate placed on a mounting surface such as a work table or work line (not shown), and the frame-shaped base 20 parallel to one surface (first main surface 21a). A pair of shaft support portions 40 rotatably supported around a rotation axis O3 extending in a shape, and a pair of fixed support columns 50 each having the pair of shaft support portions 40 at the upper portion and erected from the base 30. ing. As a result, the jig body 20A can rotate around the rotation axis O3 above the base 30 with the back cover 4 and the lid member 10 fixed to the frame-shaped base 20 (FIG. 11B). And FIG. 12B).

  The shaft support portion 40 includes a shaft portion 41 that extends along the rotation axis O3 on the frame-like base 20 side, and a bearing portion 42 that supports the shaft portion 41 on the fixed support column 50 side. The shaft portion 41 is provided so as to be fixedly arranged at the center of a predetermined opposing side portion where the first and second fixing means 23 and 24 are formed in the frame-shaped base 20. Further, the shaft support portion 40 is formed so that the frame-like base 20 can rotate around the rotation axis O3 within a predetermined rotation angle range. As a specific aspect, the shaft portion 41 is formed with a groove portion 41a extending in the circumferential direction within a predetermined angle range on the peripheral wall portion, while the bearing portion 42 is inserted into the groove portion 41a. The regulation pin 42a is fixedly arranged. The frame-shaped base 20 can be rotated between rotation angle positions at which the regulation pins 42a abut against both end portions in the circumferential direction of the groove 41a by the grooves 41a and the regulation pins 42a. In addition, the control pin 42a is arrange | positioned so that it may be inserted from the downward side with respect to the groove part 41a of the axial part 41, as shown to FIG. 13AB.

  In the embodiment according to the second modified example, as shown in FIG. 13A, the first main surface 21a to which the back cover 4 is fixed is the upper rotation position (the second main surface 21b faces the base 30). 13B and the rotation position where the second main surface 21b to which the lid-like member 10 is fixed faces the front (rotation position orthogonal to the base 30 in a side view) as shown in FIG. 13B. Rotational displacement is possible. That is, the shaft support portion 40 fixes the frame-shaped base 20 so as to be rotatable within a predetermined rotation angle range of 270 degrees. Note that the shaft support portion 40 may be formed such that the posture of the frame-like base 20 can be temporarily held at every predetermined rotation angle. Thereby, even if the operator does not hold the frame-shaped base 20 by hand, the posture is temporarily held, so that the efficiency and safety of the assembly work can be improved.

  In addition, as shown in FIG. 10, the jig body 20A has a region (on the left side in the drawing) on one side of the base 30 with the rotation axis O3 as a boundary when the base 30 (jig body 20A) is viewed from above. An area (hereinafter also referred to as a first area 31) and a first movable support column 60, and the area on the other side of the base 30 (an area on the right side in the drawing; hereinafter also referred to as a second area 32). And a second movable strut 70 provided.

  The first movable strut 60 abuts the lower surface of the frame-shaped base body 21 at a position spaced in the radial direction of the rotation axis O3 and restricts rotation in one direction (counterclockwise rotation in FIG. 11B). The first restriction state (see FIG. 11B) to be changed and the first retraction state (see FIG. 12A) to retreat from the rotation trajectory of the frame-like base 20 can be changed. As a specific aspect, the first movable support column 60 is provided in the vicinity of the peripheral edge of the base 30 parallel to the rotation axis O3 from two positions at a predetermined distance along the rotation axis O3. It is formed in a gate-like form (inverted U-shaped form, horizontal U-shaped form) to be connected. That is, the first movable column 60 includes a rectangular columnar lower base end portion 61 that rises from the base 30 side to a midway position closer to the upper portion, and a boots-like (reverse L-shaped) upper side from the midway position to the front end. The distal end 62 is connected to the lower proximal end 61 and the upper distal end 62, and the upper distal end 62 can be swung around the swing axis O4 parallel to the rotation axis O3 with respect to the lower proximal end 61. And a columnar or cylindrical coupling portion 64 that couples two upper end portions 63 that are separated from each other by a predetermined distance.

  The second movable column 70 abuts the lower surface of the frame-shaped base 20 at a position spaced in the radial direction of the rotation axis O3 and restricts rotation in the other direction of the frame-shaped base 20 (clockwise rotation in FIG. 11B). It is possible to change between a two-restricted state (see FIG. 11B) and a second retracted state (see FIG. 12A) that retracts from the rotation trajectory of the frame-shaped base 20. As a specific aspect, the second movable support column 70 is erected in the vicinity of the peripheral portion of the base 30 parallel to the rotation axis O3 from two positions at a predetermined distance along the rotation axis O3. It is formed in a gate-like form (inverted U-shaped form, horizontal U-shaped form) to be connected. That is, the second movable strut 70 includes a prismatic lower base end portion 71 that rises from the base 30 side to a midway position closer to the upper part, and a boot-like (reverse L-shaped) upper side from the midway position to the front end. The distal end portion 72 is connected to the lower proximal end portion 71 and the upper distal end portion 72, and the upper distal end portion 72 can be swung around the swing axis O5 parallel to the rotation axis O3 with respect to the lower proximal end portion 71. And a columnar or cylindrical connecting portion 74 that connects two upper end portions 73 separated by a predetermined distance.

  Here, in the jig body 20A, when the first movable support 60 is in the first restricted state and the second movable support 70 is in the second restricted state, the frame-shaped base 20 can rotate in one direction and the other. At the same time, it is held in a restricted rotation restricted state (see FIG. 11AB). In addition, since the frame-shaped base 20 is fixed so as to be rotatable in the above-described predetermined rotation angle range via the shaft support portion 40, the first main surface 21a is positioned on the lower side from the rotation angle (posture) of FIG. 11B. Even in the rotation angle rotated 180 degrees counterclockwise, the rotation can be held in the rotation restricted state in which the rotation in one direction and the other direction is simultaneously restricted.

  The first movable strut 60 and the second movable strut 70 are erected at substantially the same height from the base 30, and the frame-shaped base 20 is held parallel to the base 30 in the rotation restricted state. Will be. Thereby, by setting the frame-shaped base 20 in the rotation and rotation-restricted state, the back cover 4 and the lid-shaped member 10 can be easily held at predetermined positions of the frame-shaped base 20, and eventually by the fastening member 5 v The accessory device 5 can be stably fixed to the back cover 4. That is, the assembly process described in the above embodiment can be realized more easily and stably.

  Returning to the description of the first movable support column 60, the first restriction state of the first movable support column 60 is that the upper distal end portion 62 rises along the extension line of the lower proximal end portion 61 by the joint portion 63. The first retracted state is formed when the upper end portion 62 is rotationally displaced from below the frame-shaped base 20 to the outside and the joint portion 63 is bent. An upper end portion of the upper end portion 62 is formed with a guide portion 62a that is inclined so as to enter inside as it goes upward (tip). Thereby, the 1st movable support | pillar 60 is the case where the frame-shaped base 20 (reinforcement part 25) which rotates to another direction (counterclockwise in FIG. 11B, FIG. 12B) contact | abuts from the downward direction in the 1st control state (pressing). In response to the contact, the rotation is changed to the first retracted state, and the rotation in the other direction is allowed.

  Further, the second restricting state of the second movable support column 70 is formed by the upper tip portion 72 rising along the extension line of the lower base end portion 71 by the joint portion 73, and the second retracted state is the upper retreating state. The distal end portion 72 is formed by the rotational displacement of the frame-shaped base 20 from the lower side to the outer side and the joint portion 73 being bent. The upper end portion of the upper end portion 72 is formed with a guide portion 72a that is inclined so as to enter inside as it goes upward (the end). Thereby, when the frame-shaped base 20 (reinforcing portion 25) that rotates in one direction (clockwise in FIG. 11B) abuts (presses) from below in the second restricted state, In response to the contact, the state changes to the second retracted state, and the rotation in the one direction is allowed.

  In addition, the frame-shaped base body 21 of the frame-shaped base 20 is reinforced with a metal plate or the like over the first main surface 21a, the side surface, and the second main surface 21b at the portion where the upper end portions 62, 72 are in contact. A portion 25 is formed. Further, the reinforcing portion 25 is formed to have a protruding portion 25a on the surface side on the counterclockwise leading side around the rotation axis O3. Thereby, by changing the height of the first movable column 60 and the second movable column 70 by the amount of the protrusion 25a, it is possible to prevent and prevent misassembly by accurately adjusting the direction and position of each assembly. The upper end portions 62 and 72 are urged from the first and second retracted states to the first and second restricted states by urging means (not shown), and contact (press) from the reinforcing portion 25. If is released, the mode automatically shifts to the first and second restricted states.

  Moreover, the 1st movable support | pillar 60 is supported by the hinge part 65 by the inner surface side (2nd movable support | pillar 70 side) with respect to the base 30, as shown to FIG. 13B thru | or FIG. As a result, the first movable column 60 can fall on the base 30. Further, the first movable support column 60 is formed with a collar portion 66 in a gate shape (inverted U shape, horizontal U shape) along the inside (opposite surfaces) of the pair of lower base end portions 61. ing. The flange portion 66 is provided so as to be able to reciprocate along the longitudinal direction of the lower base end portion 61, and fits into a hole receiving portion 34 formed on the base 30 corresponding to the flange portion 66. In the standing state. Therefore, by releasing the fitting between the flange portion 66 and the hole receiving portion 34, the first movable strut 60 is laid down via the hinge portion 65 and is received by the buffer portion 35 provided on the base 30. become. The flange 66 is biased by the coil spring 66a toward the base end side (downward) of the lower base end portion 61.

  As a result, as shown in FIGS. 13B to 15, the first movable support column 60 falls on the base 30 via the hinge portion 65 when the frame-shaped base 20 is in the rotational angle position where the frame-shaped base 20 stands up. Further, it is possible to change to the third restricted state in which the frame-like base 20 is brought into contact with the base 30 at a position closer to the base 30 than in the first restricted state and the rotation in the other direction of the frame-like base 20 is restricted. At this time, in the second modification, as shown in FIG. 13B, the end of the groove 41a abuts against the regulation pin 42a in a predetermined rotation angle range by the shaft portion 40 of the frame-shaped base 20, and the rotation is performed in one direction. Is a regulated rotational angle position. That is, the frame-shaped base 20 is held in a rotation restricted state in which the rotation in one direction and the other direction is simultaneously restricted. Accordingly, if only the lid-like member 10 is removed, the accessory device 5 itself and its assembled state can be efficiently inspected, and the assembly process of the back panel unit 3 can be further facilitated. it can.

  Here, the rotation angle range of the frame-shaped base 20 by the shaft support portion 40 is not limited to the above-mentioned 270 degree range, and is appropriately set according to the range (length) of the groove portion 41 a formed in the peripheral wall portion of the shaft portion 41. can do. For example, as shown in FIG. 13A, the first main surface 21a to which the back cover 4 is fixed is the upper rotation position (the second main surface 21b is opposite to the base 30) and the second main surface. You may make it rotationally displace between the rotation position (the 1st main surface 21b opposes the base 30) in which the surface 21a becomes an upper side. That is, the shaft support portion 40 may fix the frame base 20 so as to be rotatable within a predetermined rotation angle range of 180 degrees. According to this, at the rotation angle position of the frame-shaped base 20, the rotation angle position where the end of the groove portion 41a and the restriction pin 42a abut and the rotation in one direction or the other direction is restricted, and the first movable column 60 Since the rotation angle position held in the rotation restricted state in which the rotation in the one direction and the other direction is simultaneously restricted by the second movable support column 70 coincides, the rotation is performed only in the predetermined direction from the predetermined rotation restricted state. As a result, the assembling work of the back panel unit 3 can be performed efficiently.

  In the present invention, as an example of a gaming machine, a jig for assembling a back panel unit constituting a game board unit of a pachinko machine has been described. However, for example, a back panel unit such as an arrange ball game machine or a sparrow ball game machine may be used. The present invention can be applied to an assembly jig provided.
