Description

  The present invention relates to a gaming machine such as a pachinko machine.

  Generally, in gaming machines such as pachinko machines, a gaming machine main body (inner frame) is provided to be openable and closable with respect to a fixed frame (outer frame) from the viewpoint of maintenance and the like. Therefore, the gaming machine is provided with a locking device so that a person other than the store clerk cannot open the gaming machine body without permission. Such a locking device includes a cylinder lock that is operated using a dedicated key, a plurality of hook members that are detachably attached to a plurality of locked portions that are provided on a fixed frame, and a cylinder that uses a key. There has been known one provided with a transmission mechanism for interlocking a plurality of scissors members according to an unlocking operation of the lock. And in a locked state, each gutter member engages with the corresponding to-be-latched part, respectively, and a game machine main body cannot open | release with respect to a fixed frame. On the other hand, when the cylinder lock is unlocked with a dedicated key, the hook members are simultaneously detached from the locked portions via the transmission mechanism, and the gaming machine main body can be opened.

  In the game hall, illegal actions to acquire a lot of game media are carried out by illegally unlocking the gaming machine main body during operation and illegally operating or replacing the control device provided on the back side of the main body There is. Such unauthorized unlocking is usually performed by inserting a wire such as a wire from the gap between the gaming machine main body and the fixed frame, and hooking the wire to a hook member of the locking device and moving it in the unlocking direction. When an unauthorized unlocking operation is performed on the heel member, the heel member is detached from the locked portion, and the gaming machine main body can be opened.

Conventionally, the fixed frame that supports the gaming machine main body is configured in a rectangular frame shape by assembling wooden members. On the other hand, in recent years, in consideration of durability, recyclability, and the like, a fixed frame constituted by a metal member such as an aluminum alloy instead of a wooden member has been proposed. For example, the upper side frame component, the lower frame component, the left frame component, and the right frame component are all formed integrally by die-molding such as aluminum die casting, or only a part of the frame components on both the left and right sides. There is a hybrid type using a manufactured member (for example, see Patent Document 1).

  When the front frame set 14 is unlocked, a key is inserted into the key hole 702 of the cylinder lock 700 and rotated counterclockwise when viewed from the front side of the pachinko machine 10 (see FIG. 1). As a result, the cam plate 720 rotates in the same direction, and the upper engagement claw 720a pushes down the first sliding rod 605 downward against the tensile force of the coil spring C1.

  When the first sliding rod 605 slides downward, the engagement of all the front frame set locking portions 610, 611, 612 and the front frame set collars 17a, 17b, 17c is released, and the front frame set 14 Opening is allowed.

  Next, locking and unlocking of the inner frame 12 will be described in detail. In the locked state of the inner frame 12, when the second sliding rod 635 takes the reference position, the inner frame flange portions 637 and 638 are engaged with the flange receiving portions 84 and 85 of the outer frame 11. Opening is restricted (see FIG. 17).

  Then, when unlocking the inner frame 12, a key is inserted into the key hole 702 of the cylinder lock 700 and rotated in the clockwise direction when viewed from the front side of the pachinko machine 10. As a result, the cam plate 720 rotates in the same direction, and the lower engagement claw 720b pushes up the second sliding rod 635 upward against the tensile force of the coil spring C1. When the second sliding rod 635 slides upward, the engagement between the inner frame collar portions 637 and 638 and the collar receiving portions 84 and 85 is released, and the opening of the inner frame 12 is allowed (see FIG. 18). .

  Next, the locking and unlocking of the second control board unit 202 and the back pack unit 203 will be described in detail.

  In the locked state of the second control board unit 202, the second sliding bar 635 takes the reference position as in the case of the inner frame 12, so that the board unit bar 620 can receive the metal fitting 205 of the second control board unit 202. And the opening of the second control board unit 202 is restricted.

  Similarly, in the locked state of the back pack unit 203, when the second sliding bar 635 takes the reference position, the back pack bar parts 621 and 622 are engaged with the receiving bracket 204 of the back pack unit 203, and the back pack unit 203 is engaged. The opening of the unit 203 is restricted.

  Then, when unlocking the second control board unit 202 and the back pack unit 203, after opening the inner frame 12, the key inserted into the key hole 702 of the cylinder lock 700 is clicked as in the case of the inner frame 12. Rotate clockwise as viewed from the front side of the machine 10. As a result, when the cam plate 720 rotates in the same direction and the lower engagement claw 720b pushes up the second sliding rod 635 upward against the tensile force of the coil spring C1, the board unit collar 620 and The engagement with the receiving metal fitting 205 is released, the opening of the second control board unit 202 is allowed, and the engagement between the back pack collar parts 621 and 622 and the receiving metal fitting 204 is released, and the back packing unit 203 is opened. Is acceptable.

  As a procedure for closing the inner frame 12 and the like, the inner frame 12 in the open state as shown in FIG. 18 is closed, and the inclined portions of the heads of the inner frame collar parts 637 and 638 are the hook receiving parts 84 and 85. When it hits the lower edge of the hole portions 84a and 85a, an upward external force is applied to the second sliding rod 635, and the second sliding rod 635 slides upward against the tensile force of the coil spring C1. Move. Then, when the heads of the inner frame collar parts 637 and 638 get over the lower edge parts of the hole parts 84a and 85a of the collar receiving parts 84 and 85, the second sliding collar 635 is restored to the original by the tensile force of the coil spring C1. Return to position. Thereby, the inner frame collar parts 637 and 638 are locked to the collar receiving parts 84 and 85, and the inner frame 12 is in a closed state as shown in FIG. Of course, the front frame set 14, the second control board unit 202, and the back pack unit 203 can be locked by the same locking method.

  As described above in detail, in the present embodiment, since the left side frame constituting portion 11c and the right side frame constituting portion 11d are made of an extruded material made of an aluminum alloy, durability is improved as compared with the case of being made of wood. At the same time, recyclability is improved.

  Further, if the left side frame constituting part 11c and the right side frame constituting part 11d are made of metal, the thickness can be made relatively thin while maintaining the necessary strength. In this way, as in the pachinko machine 10, in the gaming machine whose outer shape is configured to be substantially the same shape as a standard, the space surrounded by the outer frame 11 is expanded in the left-right width direction, The space can be used more effectively.

  Furthermore, in the conventional wooden outer frame, router processing or the like has been applied to the frame components on both the left and right sides in order to expand the inner space in the left and right direction. Such work is not required, and the work process can be simplified.

  In addition, a plurality of protrusions such as ribs 821 and 822 protruding inward of the outer frame 11 are formed along the vertical direction on the inner side surfaces of the left side frame constituting portion 11c and the right side frame constituting portion 11d. Thereby, the clearance gap between the inner frame 12 and the outer frame 11 can be reduced. Therefore, even when a wire rod such as a wire is inserted from the gap between the inner frame 12 and the outer frame 11 and an unauthorized act of unlocking the inner frame 12 is attempted, the inner frame collars 637 and 638 of the locking device 600 are used. It is possible to make it difficult to wrap the wire up to the engagement portion between the hook receiving portions 84 and 85. As a result, the defense performance against unauthorized unlocking using a wire or the like can be enhanced while the thicknesses of the left side frame constituting part 11c and the right side frame constituting part 11d are made relatively thin. That is, it is possible to achieve both of the effects of reducing the thickness of the left side frame constituting part 11c and the right side frame constituting part 11d and improving the defense performance.

  Furthermore, when the inner frame 12 is closed, the folded-back portion 816 of the right side frame constituting portion 11d is fitted into the groove portion 820 of the inner frame 12. Further, the inner frame 12 is formed with a side wall portion 901c of a mounting groove 901 that separates the locking device 600 from the ribs 821, 822 and the like. Thereby, the said effect can be heightened further.

  In addition, by forming a plurality of protrusions such as the ribs 821 and 822, it is possible to suppress distortion and bending of the left side frame constituting part 11c and the right side frame constituting part 11d. As a result, since the strength of the left side frame constituting part 11c and the right side frame constituting part 11d is increased, it is possible to further reduce the thickness, and to further reduce the weight and further expand the internal space.

  Conventionally, when installing a pachinko machine in a game hall, it is common to fix the wooden outer frame by hitting it with a nail or the like at the game machine installation location. Therefore, if the frame configuration portions 11a and 11b on both the upper and lower sides are made of a wooden plate material as in this embodiment, the pachinko machine 10 can be fixed with nails or the like as in the prior art, so that the game hall side is newly fixed. There is no need to prepare means, and the burden on the game hall side is reduced.

  Moreover, since the left side frame constituting part 11c and the right side frame constituting part 11d are made of an extrusion molding material, it is not necessary to perform mold forming using a mold apparatus, so that the manufacturing process can be simplified.

  Further, the main body wall portions of the left side frame constituting portion 11c and the right side frame constituting portion 11d are formed by continuously forming a concave wall portion having a substantially U-shaped cross section and a convex wall portion having a substantially inverted U-shaped cross section in the width direction alternately. It has been configured. As a result, the boundary portion between the concave wall portion and the convex wall portion functions as a reinforcing rib. The thickness can be reduced. As a result, more effective use of space can be achieved.

  Further, in the present embodiment, an extending wall portion 830 that covers the entire upper and lower sections corresponding to the locking device 600 from the back side of the inner frame 12 is formed in the right side frame constituting portion 11d. Accordingly, it becomes more difficult to allow a wire rod or the like to enter from the back side of the outer frame 11 and to operate each flange portion such as the inner frame flange portions 637 and 638 by the wire rod or the like. As a result, the defense performance can be further improved.
