In the pachinko machine 100, the locking device 35 forms and releases the state in which the inner frame 1 is accommodated in the outer frame 2 and the state in which the front frame 4 is attached to the inner frame 1 as follows.
The front frame locking device 33 and the middle frame locking device 32 provided on the locking device 35 are respectively saddle-shaped ridges protruding from the middle frame 1 toward the front frame 4 and from the middle frame 1 toward the outer frame 2. A shaped portion 47 is formed. In the front frame 4 and the outer frame 2, an engaging portion (not shown) is provided at a position facing the hook-shaped portion 47 of the front frame locking tool 33 and the middle frame locking tool 32.
When the entire front frame 4 is attached to the front surface of the middle frame 1, the hook-shaped portion 47 of the front frame locking tool 33 is engaged with the engagement portion of the front frame 4, thereby causing the front frame 4 to move forward from the middle frame 1. Are not easily opened. Further, when the middle frame 1 is accommodated in the outer frame 2, the hook-shaped portion 47 of the middle frame locking tool 32 engages with the engaging portion of the outer frame 2, whereby the middle frame 1 is moved forward from the outer frame 2. Are not easily opened.

  The locking mechanism 34 provided in the locking device 35 is formed with a key hole for inserting a key on the front surface, and the front frame locking tool 33 and the middle frame locking tool according to the rotation of the key inserted into the key hole. A stress is applied to 32 in the vertical direction. When the front frame latching tool 33 and the middle frame latching tool 32 receive stress from the locking mechanism 34, they slide up and down along the longitudinal direction of the surrounding frame portion 16, and the front frame latching tool 33 and the middle frame latching tool 32 are engaged. The locked state between the hook-shaped portion 47 of the stopper 32 and the engaging portion of the front frame 4 or the outer frame 2 is formed or released. Then, in response to the formation or release of the locking state between the hook-like portion 47 and the engagement portion, the locking state of the middle frame 1 and the outer frame 2 or the middle frame 1 and the front frame 4 is formed or released. .

  For example, in the pachinko machine 100, the locking mechanism 34 includes a cylinder lock 58, the middle frame locking member 32 includes a spring and is always biased upward, and the engaging portion has a recessed portion upward. The hook-shaped portion 47 can be configured to engage with the recessed portion of the engaging portion. In such a case, normally, the inner frame 1 does not open to the front side of the outer frame 2, and when the key is inserted into the cylinder lock 58 and rotated, the locking mechanism 34 is acted upward by the spring. A stress that moves downward against the force is applied to the middle frame locking tool 32, and the state in which the hook-shaped portion 47 is engaged with the recessed position of the engaging portion is released, and the middle frame 1 is It can be opened in front of the frame 2.

  Thus, when the locked state of the middle frame 1 and the outer frame 2 or the locked state of the middle frame 1 and the front frame 4 is released, the middle frame 1 can be opened forward with respect to the outer frame 2, and The front frame 4 can be opened toward the front direction with respect to the middle frame 1.

  In this pachinko machine 100, as described above, the right surrounding frame portion 16d is formed so as to protrude slightly outward toward the front and cover the entire locking mechanism 34 from the front. 2, the locking mechanism 34 is surrounded by the thin portion 28 and the raised portion 27 of the right surrounding frame portion 16d and the outer frame thin portion 45 and the outer frame raised portion 44 of the right accommodating frame portion 39d ( FIG. 3). Therefore, according to this pachinko machine, since the space in which the locking mechanism 34 of the locking device 35 is disposed can be isolated from the space outside the pachinko machine, unauthorized access to the space in which the locking mechanism 34 is disposed from outside the pachinko machine. It can prevent intrusion and contribute to preventing goto.

  In the pachinko machine 100, the thin portion 28 of the middle frame 1 is formed so that the side surfaces of the game board 3 are opposed to each other. Therefore, in this gaming machine, the game board holding space 9 can be expanded, and the area in which the game board 3 can be disposed can be sufficiently expanded. The thin portion 28 and the thin outer frame portion 45 are formed on the middle frame 1 and the outer frame 2 so as to face each other. Therefore, there is no dead space between the outer frame 2 and the middle frame 1, and the space efficiency is further improved.

  Further, in the pachinko machine 100, a raised portion 27 and an outer frame raised portion 44 are formed on the middle frame 1 and the outer frame 2, respectively, and the middle frame 1 and the outer frame 2 are formed by the raised portion 27 and the outer frame raised portion 44. The strength of the can be ensured.

  Further, in this pachinko machine 100, the left and right surrounding frame portions 16 of the middle frame 2 are metal-formed. Therefore, even if the thin portion 28 is formed in the middle frame 2 to be thin, the strength of the pachinko machine 100 can be ensured as compared with the case where the thin frame 28 is formed using resin or wood.

  In this pachinko machine 100, the upper and lower surrounding frame portions 16 are resin-molded, and the weight of the pachinko machine 100 can be reduced compared to the case where it is metal-molded. In addition, if the upper and lower surrounding frame portions 16 are resin-molded, a sufficient degree of design freedom can be secured, so that the design shape of each member constituting the back member 8 attached to the upper and lower surrounding frame portions 16 is changed. Can respond immediately.

  Furthermore, since the upper and lower surrounding frame portions 16 are resin-molded, the game balls, which are metal bodies, flow down in the vertical direction as compared with the case where the upper and lower surrounding frame portions are metal-molded. The possibility that an excessively loud metal sound is generated when hitting 16 is suppressed, and the possibility of reducing the interest of the player is also suppressed.

  Further, in the pachinko machine 100, the left and right housing frame portions 39 are formed such that the outer frame raised portion 44 projects rearward from the raised portion 27 of the middle frame 1. When the pachinko machine 100 is formed in this way, the outer frame ridges 44 are formed in the outer frame 2 more than the outer frame ridges 44 formed in front of the ridges 27 of the middle frame 1. Since the restriction of the outer frame raised portion 44 due to the presence of the frame 1 is small, the outer frame raised portion 44 can be formed larger, and sufficient strength can be secured in the outer frame 2 of the pachinko machine 100.

  In this pachinko machine 100, the outer frame thin portion 45 is arranged so as to be located on the side of the outer frame raised portion 44 in the direction of taking out the game board 3 from the game board holding space 9 in the middle frame 1. If the outer frame 2 is configured so that the outer frame raised portion 44 is positioned in the direction of taking out the game board 3 more than the outer frame thin portion 45, the outer frame raised portion 44 interferes with the removal of the game board 3. To do. In such a case, in order to actually remove the game board 3 from the middle frame 1, the middle frame 1 is once removed from the outer frame 2 until the outer frame raised portion 44 of the outer frame 2 does not interfere with the removal of the game board 3. After opening, it is necessary to take out the game board 3, and the opening operation of the middle frame 1 becomes complicated. On the other hand, since the outer frame thin part 45 is formed thinner than the outer frame raised part 44, it does not become an obstacle to the take-out direction of the game board 3. Then, this pachinko machine 100 is arranged such that the outer frame thin part 45 is positioned on the direction side of taking out the game board 3 from the game board holding space 9 in the middle frame 1 from the outer frame raised part 44. The game board 3 can be easily attached and detached while the middle frame 1 is attached to the outer frame 2 without performing the operation of releasing the middle frame 1 from the outer frame 2. Can be easily performed.

  As described above, in the present embodiment, the first machine frame including the upper, lower, left, and right surrounding frame parts that surround the game board and can be detachably held, and surrounds the first machine frame and can be opened and closed. In a gaming machine having a second machine frame with possible upper, lower, left, and right housing frame portions, the left and right enclosure frame portions and the left and right housing frame portions are respectively inwardly of the gaming machine in the front-rear direction rear end side. The ridges and outer frame bulges that protrude upward are formed, and a thin part that is thinner than the bulge part and a thin outer frame that is thinner than the outer frame bulge part in front of the bulge part and outer frame bulge part Are formed toward the front end in the front-rear direction of the gaming machine, and the thin portion and the outer frame thin portion are formed to face each other when the first machine frame is housed in the second machine frame. The pachinko machine 100 is used as an example of the gaming machine. It explained.

  In particular, in the present embodiment, the first machine frame including the upper, lower, left and right surrounding frame parts that surround the game board and can be detachably held, and the first machine frame are surrounded and freely opened and closed. In a gaming machine having a second machine frame that includes upper, lower, left, and right storage frame portions, the first machine frame is located behind a rear end position of a portion facing the left and right surrounding frame portions and the side of the game board. The left and right surrounding frame portions located at the rear are formed with raised portions that protrude inward of the first machine frame, and are thinner than the raised portions in front of the first raised portions in the left and right surrounding frame portions. And the second machine frame is located inside the second machine frame at the rear part of the left and right storage frame parts located behind the rear end position of the opposing part of the left and right storage frame parts and the thin part. The outer frame bulge is formed in front of the outer frame bulges in the left and right housing frame parts. A thin outer frame thin portion is formed, and the outer frame raised portion is a second machine frame through which the raised portion passes when the first machine frame housed in the second machine frame is opened and closed. The case where it is formed outside the inner space has been described in detail as an example of the first embodiment.

In the gaming machine of the present invention, the thin portion may be formed to have a partial thickness in the width direction partially in the outer direction of the first machine frame. In addition, the outer frame thin portion may be partially formed with a width and thickness in the inner direction and / or the outer direction of the second machine frame to form the outer frame partial width thick portion.
Furthermore, the partial width thick portion and the outer frame partial width thick portion, and the raised portion and the outer frame raised portion may be formed hollow.
This will be described using the pachinko machine 100 as follows.

That is, in the pachinko machine 100, as shown in FIG. 7, the thin portion 28 of the left and right surrounding frame portions 16 has a partial width that is slightly wider than the thickness of the thin portion 28 in the outer direction of the middle frame 1. The thick part 50 may be partially formed. In addition, the outer frame thin portion 45 of the left and right housing frame portions 39 has an outer frame portion width thick portion that is slightly wider than the thickness of the outer frame thin portion 45 in the inner and / or outer direction of the outer frame 2. 51 may be partially formed.
According to such a pachinko machine 100, the strength of the frame portion can be further increased by forming the partial width thickness portion 50 and the outer frame partial width thickness portion 51 in the thin portion 28 and the outer frame thin portion 45. .

  In the pachinko machine 100, as shown in FIGS. 3 and 7, the partial width portion 50, the outer frame partial width portion 51, the raised portion 27, and the outer frame raised portion 44 are formed hollow.

  The partial width thick part 50, the outer frame partial width thick part 51, the raised part 27, and the outer frame raised part 44 are not limited to being formed hollow, but may be formed solid. However, if the raised portion 27, the outer frame raised portion 44, the partial width thick portion 50, and the outer frame partial width thick portion 51 are formed hollow, it is only lighter than the case where they are formed solid. It is preferable at the point which can provide the frame part which is excellent also in strength.

  In the left and right surrounding frame portions 16, the outer frame portion width / thickness portion 51 may be configured to be slightly wider in either the inner or outer direction, but from the point of efficiently increasing the strength of the pachinko machine 100, It is preferable to make the width and thickness both inward and outward. However, if the width is too large in the outer direction, the outer dimensions of the pachinko machine 100 will increase. If the thickness is too large in the inner direction, the outer frame 2 will be removed when the inner frame 1 is accommodated in the outer frame 2. Thus, the outer frame portion width thick portion 51 collides with the inner frame 1 and the inner frame 1 cannot be properly accommodated in the outer frame 2.

Further, in the pachinko machine 100, the screw holes 52 formed in the left and right surrounding frame portions 16 are portions excluding the formation portion of the outer frame portion width thick portion 50 in the outer frame thin portion 45 of the left and right housing frame portions 39 ( It is preferably arranged so as to face the partial width thick portion non-forming portion 65). According to such a pachinko machine 100, since the outer frame portion width thick portion 50 is formed, the screw head of the screw inserted into the screw hole 52 is a pan head having a thickness larger than that of the flat head. Even in this case, a space (in FIG. 7) between the region facing the thin portion 28 of the partial width / thickness portion non-forming portion 65 and the region facing the partial width / thickness portion non-forming portion 65 of the thin portion 28. The screw head can be accommodated in the space R). In the pachinko machine 100, various members constituting the pachinko machine and a part thereof may be arranged in the space R in addition to the screw heads.
Therefore, in this pachinko machine 100, the outer frame portion width / thickness part 50 can further secure the space R as a space where the screw head and the members constituting the pachinko machine are arranged while further increasing the strength of the frame part. it can.

  In the present invention, the cross-sectional shape intersecting with the longitudinal direction of the surrounding frame portion 16 for the raised portion 27 and the partial width thick portion 50 is not particularly limited, and the cross-sectional shape is triangular or square in addition to the P-shaped cross section. A polygonal shape such as a shape, a shape in which corners of a polygonal shape are chamfered, a cross-section may be a circle or a circle-like shape. The same applies to the cross-sectional shape that intersects the longitudinal direction of the housing frame portion 39 with respect to the outer frame raised portion 44 and the outer frame partial width thick portion 51.

  The raised portion 27 and the outer frame raised portion 44 are formed so that the bent tip faces the direction of the plate material when the raised portion 27 and the outer frame raised portion 44 are formed by bending a flat plate material. Is done. The bent tip may be separated without directly contacting the plate material. However, when the tip is in contact with the plate material, the folded tip is separated without directly contacting the plate material, for example, L Resistive force when stress such as torsion is applied to the outer frame 2 as compared with the case where the storage frame portion 39 or the surrounding frame portion 16 having a letter-shaped, T-shaped or U-shaped cross-sectional shape is formed. Is increased, and the impact resistance of the pachinko machine 100 is improved, which is preferable.

In the gaming machine of the present invention, in the state where the first machine frame is accommodated in the second machine frame, the partial width thick portion and the outer frame partial width thick portion, and the raised portion and the outer frame raised portion are They may be arranged at positions shifted alternately in the front-rear direction. Further, in this gaming machine, in a state where the first machine frame is housed in the second machine frame, the partial width thick portion is disposed on the front side in the front-rear direction of the gaming machine relative to the outer frame partial width thick portion, and is raised. The portion may be arranged on the rear side in the front-rear direction of the gaming machine with respect to the outer frame part width thick part, and on the front side in the front-rear direction of the game machine with respect to the outer frame raised part.
This will be described using the pachinko machine 100 as follows.

  That is, in the pachinko machine 100, in the state in which the inner frame 1 is accommodated in the outer frame 2, the partial width thick part 50 is disposed on the front side in the front-rear direction of the pachinko machine 100 with respect to the outer frame partial width thick part 51. May be arranged on the rear side in the front-rear direction of the pachinko machine 100 with respect to the outer frame partial width thick part 51 and on the front side in the front-rear direction of the pachinko machine 100 with respect to the outer frame raised part 44. In this case, the partial width thick portion 50 and the outer frame partial width thick portion 51, and the raised portion 27 and the outer frame raised portion 44 are arranged at positions shifted alternately in the front-rear direction of the pachinko machine 100. If it carries out like this, it can suppress that these are arrange | positioned in the position which overlaps in the front-back direction. In the pachinko machine 100, if there is no overlap of thick portions in the left-right direction, the thick and thick portions can be formed while suppressing the formation of dead spaces. Therefore, according to such a pachinko machine 100, the area where the pachinko machine 100 can be efficiently installed can be expanded, and the strength of the pachinko machine 100 can be further secured.

  And this pachinko machine 100 is arranged in the position shifted mutually from the front in the order of partial width thick part 50 and outer frame partial width thick part 51 from back. According to such a pachinko machine 100, it is possible to eliminate the need to consider the possibility that the partial width / thickness portion 50 is caught by the outer frame partial width / thickness portion 51 when the middle frame 1 is released from the outer frame 2.

Further, in the gaming machine of the present invention, the outer frame portion width / thickness portion is larger than the space inside the second machine frame through which the raised portion passes when the first machine frame housed in the second machine frame is opened and closed. Is also formed on the outside.
This will be described using the pachinko machine 100 as follows.

  That is, in the pachinko machine 100, the outer frame partial width thick portion 51 is outside the space (space T in FIG. 6) region occupied by the inner frame 1 in the outer frame 2 when the inner frame 1 is accommodated in the outer frame 2. And is formed outside the space inside the outer frame 2 (the space K in FIG. 6) through which the raised portion 27 passes when the middle frame 1 accommodated in the outer frame 2 is opened and closed. In such a pachinko machine 100, it is possible to eliminate the possibility that the outer frame partial width thick part 51 and the partial width thick part 50 collide when the middle frame 1 is released from the outer frame 2.

  In the present embodiment as described above, the raised portion 27, the thin portion 28, the partial width thick portion 50, the outer frame raised portion 44, the outer frame thin portion 45, and the outer frame partial width thick portion 51 are respectively left and right. In this pachinko machine 100, the raised portion 27, the partial width thick portion 50, and the outer frame portions 16c and 16d and the left and right receiving frame portions 39c and 39d are continuously formed in the longitudinal direction. The frame raised portion 44 and the outer frame partial width thick portion 51 may be formed intermittently and discontinuously. However, as shown in the present embodiment, the raised portion 27, the thin portion 28, the partial width thick portion 50, and the outer frame raised portion 44, the outer frame thin portion 45, and the outer frame partial width thick portion 51 are continuously formed. In this case, there is an advantage that the left and right surrounding frame portions 16 and the left and right housing frame portions 39 can be easily formed, and the strength can be improved as compared with the case where they are formed discontinuously.

In the present invention, among the upper, lower, left and right storage frame portions 39a to 39d of the outer frame 2, the outer frame raised portion 44 and the outer frame thin portion 45 form at least the left storage frame portion 39c and the right storage frame portion 39d. More preferably, the upper housing frame 39a also desirably forms the outer frame raised portion 44 and the outer frame thin portion 45. If it carries out like this, the area | region which can install the game board 3 can be expanded also to an up-down direction.
Further, in the pachinko machine 100, the outer frame raised portion 44 and the outer frame thin portion 45 can be formed on any one of the upper, lower, left and right housing frame portions 39a to 39d. In that case, the outer frame raised portion 44 and the outer frame thin portion 45 are formed in the right housing frame portion 39d far from the support shaft 56 that pivotally supports the middle frame 1 among the upper, lower, left and right housing frame portions 39a to 39d. It is preferable.

  In the present invention, the raised portion 27 and the thin portion 28 can be formed on any one of the upper, lower, left and right surrounding frame portions 16 a to 16 d of the middle frame 1. In that case, it is preferable to form the raised portion 27 and the thin portion 28 in the right surrounding frame portion 16d far from the support shaft 38 that pivotally supports the front frame 4 among the upper, lower, left and right surrounding frame portions 16a to 16d.

  In the present invention, the case where the outer frame 2 is formed by joining the upper, lower, left and right housing frame portions 39 using a joining member such as the outer frame fixture 54 and a screw is described as an example, but the outer frame 2 is not limited thereto. For example, joint portions may be formed to extend at the ends of the upper, lower, left, and right housing frame portions 39, and the upper, lower, left, and right housing frame portions 39 may be joined and formed using various joining means such as bolts and nuts. Further, the pachinko machine 100 may further improve the joining strength by using a reinforcing member or the like at the joining position of the upper, lower, left, and right housing frame portions 39.

In the pachinko machine 100, the left and right housing frame portions 39 may be configured to be made of metal, like the left and right surrounding frame portions 16. That is, the housing frame part 39 forming the outer frame raised part 44 and the outer frame thin part 45 may be made of metal. In such a case, the metal forming these is preferably an aluminum alloy or a magnesium alloy. When the left and right housing frame portions 39 are formed of metal, the outer frame 2 is removed except for the housing frame portions 39 (left and right housing frame portions 39) that form the outer frame raised portions 44 and the outer frame thin portion 45. The housing frame portion 39 (upper and lower housing frame portions 39) that are configured may be formed of metal, and the entire outer frame 2 may be made of metal. The housing frame 39 made of metal can be manufactured by metal forming. Specific examples of metal forming include a method of forming by deforming extrusion of an aluminum alloy or a magnesium alloy.
When the frame portion constituting the outer frame 2 is made of metal in this way, the strength of the pachinko machine 100 can be further improved. Since the metal outer frame 2 is superior in rigidity and heat resistance as compared with the case where it is made of wood, a part of the outer frame 2 is damaged by a bent rod heated by the player, and the pachinko machine. It is possible to suppress an illegal act such as contacting an internal part from the outside.

  Further, by making the frame part constituting the outer frame 2 made of metal, a connection area of the ground wire extending from the devices installed in the pachinko machine 100 is not limited, and a wide discharge area is secured. Therefore, the discharge efficiency can be improved, and the degree of design freedom can be ensured.

  In addition, when the frame portion constituting the outer frame 2 is manufactured from an aluminum alloy among metals, like the left and right surrounding frame portions 16 in the middle frame 1, the frame is reheated and melted, and then again the frame body. It can be easily reused as a molding material, and the recyclability can be improved. And the pachinko machine 100 which can respond | correspond suitably for the effective utilization of resources can be provided by improving recyclability.

  Further, when a metal having higher rigidity than wood is used as the molding material for each frame portion, the outer frame 2 can be formed thinner than the wooden frame portion. As a result, the pachinko machine 100 can expand the game board holding space 9 more efficiently.
