Only one of these notification means may be provided in the gaming machine, or both may be used together, or other means may be added.

With reference to FIG.1 and FIG.2, the specific structural example of the locking part R which is the principal part of a locking device is demonstrated.
In FIG. 1, a base member 41 having an L-shaped cross section is fixed to the open end side rear surface of the inner frame 3. Upper and lower locking solenoids 31 and 32 are surrounded by an upper and lower mounting plate 43 and fixed to upper and lower ends of a standing wall 42 provided on the base member 41. Plungers 29 and 30 of the upper and lower locking solenoids 31 and 32 are inserted into upper and lower engaging holes 27 and 28 provided in the vertical frame portion 33, and lock the inner frame 3 to the outer frame 1.

  The cylinder lock 44 attached to the base member 41 is connected to the cam mechanism 46 (see FIG. 9). In the present embodiment, the cam mechanism 46 is provided on a part of the light shielding plate 47. The cam mechanism 46 is connected to a slide member 45 provided on the opposite surface side of the standing wall 42. The slide member 45 is provided with engagement hooks (not shown) at a plurality of locations so as to be engaged with a hook receiving member (not shown) provided on the front frame 4. When the cylinder lock 44 is rotated in a predetermined direction, the slide member 45 is slid through the cam mechanism 46 and the engagement between the engagement hook (not shown) and the hook receiving metal is released to release the front frame 4 from the inner frame 3. Can do. The front frame 4 and the inner frame 3 may be locked by a locking solenoid (not shown).

FIG. 1 shows a state where the upper and lower locking solenoids 31 and 32 are OFF. At this time, the plungers 29 and 30 are inserted into the vertical engagement holes 27 and 28, and the inner frame 3 is locked. In FIG. 2, when the cylinder lock 44 is rotated in a predetermined direction, the upper and lower locking solenoids 31 and 32 are turned ON. At this time, the plungers 29 and 30 come out of the vertical engagement holes 27 and 28, and the inner frame 3 is unlocked.
In FIG. 2, since the upper and lower locking solenoids 31 and 32 are provided at the upper and lower end portions of the inner frame 3 (in the vicinity of the upper horizontal frame portion 25 and the curtain plate 17), the image processing control board 21a and the main control board 21b are connected to the vertical frame. There is no obstacle between the unit 33 and the unit 33. For this reason, there is no possibility of interfering with the outer frame 1 as the inner frame 3 is opened and closed, and the size of the image processing control board 21a and the main control board 21b is enlarged as much as possible in accordance with the enlargement of the installation area of the game board 5. be able to.

  In FIG. 8, when the inner frame 3 is opened from the outer frame 1, the trajectory drawn by the structure 61 including the image processing control board 21 a, the main control board 21 b, the variable display device 7, etc. is represented by E as the conventional rotation path. The rotation locus according to the example is displayed as F. Thereby, the installation area | region of the structure 61 provided in the back surface side of the inner frame 3 can also be expanded from the area | region G to the area | region H. FIG.

Here, the control operation of the gaming machine locking device will be described with reference to the flowchart of FIG.
The locking part R shall be in the locked state of FIG. When the key is inserted into the keyhole 16 (see FIG. 4) from the front frame 4 side and the cylinder lock 44 rotates in a predetermined direction, the inner frame release switch 36 (rotation detecting means) is turned on. It is determined whether or not the frame release switch 36 is turned on (step S1). When the inner frame release switch 36 is turned on, the process proceeds to step S2 and the upper and lower locking solenoids 31 and 32 are turned on. When the upper and lower locking solenoids 31 and 32 are turned on, the plungers 29 and 30 come out of the upper and lower engagement holes 27 and 28 in FIG. 2 and the locking portion R is unlocked.

  Next, in step S3, the main control board 21b and the like determine whether or not the inner frame open confirmation switch 37 (open / close detection means) is ON. When the inner frame release confirmation switch 37 is turned on, the inner frame 3 is separated from the outer frame 1, so that it is determined that the inner frame 3 is normally opened, and the process proceeds to step S4. When the inner frame release confirmation switch 37 is omitted, step S3 is omitted.

  In step S4, the main control board 21b and the like perform data communication of the determination result to the hall computer 35 through the external output relay board 34 (normally open data communication). Thereby, the hall computer 35 can recognize that the corresponding gaming machine is normally opened of the inner frame 3 including maintenance opening, and the open / closed state of each gaming machine can be centrally managed as data.

  Next, the process proceeds to step S5, and the main control board 21b and the like notify that the inner frame 3 is normally opened by lighting or blinking the opening notification LED 38 in a normal opening notification pattern. Alternatively, a sound is output from the speaker 40 through the sound control board 39 in a normal opening notification pattern to notify that the inner frame 3 is normally opened. Alternatively, by using these together, it is notified that the opening of the inner frame 3 of the gaming machine is a normal opening.

  Next, the process proceeds to step S6, and when the inner frame 3 released by the attendant is closed, the inner frame release confirmation switch 37 is turned off. Therefore, the main control board 21b or the like has determined whether the inner frame release confirmation switch 37 has been turned off. Determine whether. When the inner frame release confirmation switch 37 is turned off, it is determined that the inner frame 3 has been closed, and the process proceeds to step S7 to release the normal release data communication from the main control board 21b to the hall computer 35. When the inner frame release confirmation switch 37 is omitted, step S6 is omitted. Next, in step S8, the main control board 21b and the like stop lighting or blinking the open notification LED 38, stop the voice output from the speaker 40 through the voice control board 39, and perform a notification operation from the gaming machine. finish.

  In step S9, the main control board 21b determines whether the inner frame release switch 36 is turned off. When the inner frame release switch 36 is turned off, the cylinder lock 44 is locked, so that the process proceeds to step S10 and the upper and lower locking solenoids 31, 32 are turned off. When the upper and lower locking solenoids 31 and 32 are turned OFF, the plungers 29 and 30 are inserted into the upper and lower engagement holes 27 and 28 in FIG. 1 and the locking portion R is locked.

  In step S1, when the inner frame release switch 36 is in the OFF state, the main control board 21b or the like proceeds to step S11 and determines whether or not the inner frame release confirmation switch 37 is turned on. If the inner frame release confirmation switch 37 is in the OFF state, the inner frame 3 remains normally closed. Therefore, the process returns to step S1 and the main control board 21b and the like monitor the state of the inner frame release switch 36.

  In step S11, if the inner frame release confirmation switch 37 is ON, the inner frame 3 is separated from the outer frame 1 even though the inner frame release switch 36 is OFF. Are determined as abnormal opening (injustice) of the inner frame 3. Accordingly, the process proceeds to step S12, and the main control board 21b and the like perform data communication of the determination result to the hall computer 35 through the external output relay board 34 (abnormal release data communication). Thereby, abnormal opening of the inner frame 3 including unauthorized opening or failure opening can be centrally managed on the hall side, and the unauthorized monitoring system for each gaming machine can be strengthened.

  Next, the process proceeds to step S13, and the main control board 21b and the like notify the staff by lighting or blinking the opening notification LED 38 in an abnormal opening notification pattern. Alternatively, the voice is output from the speaker 40 through the voice control board 39 in the abnormal release notification pattern to notify the staff. Alternatively, by using these together, it is notified that the inner frame 3 of the gaming machine has been abnormally opened. As a result, it is easy to identify the gaming machine in which the inner frame 3 is abnormally opened, and the staff can quickly respond.

  If the key inserted into the cylinder lock 44 is turned by mistake while the inner frame 3 is opened, the inner frame release switch 36 is turned off and the upper and lower locking solenoids 31 and 32 are turned off. When the upper and lower locking solenoids 31 and 32 are turned OFF, the plungers 29 and 30 protrude from the outer edge of the inner frame while the inner frame 3 remains open. When the inner frame 3 is closed in this state, it does not close due to interference with the outer frame 1. Therefore, when the inner frame release confirmation switch 37 is turned on, the main control board 21b and the like ignore the detection result even if the inner frame release switch 36 is turned off. As a result, it is possible to eliminate a problem caused by turning a key that is erroneously inserted into the cylinder lock 44 with the inner frame 3 opened.

As described above, the locked state of the inner frame 3 is centrally managed by the main control board 21b or the like, and whether the opened state of the inner frame 3 is a normal release or an abnormal release (illegal act) for each gaming machine. Can be determined. In addition, when the main control board 21b or the like determines normal opening or abnormal opening of the inner frame 3 and determines that the inner frame 3 is abnormally opened, an unauthorized action or failure occurs by notifying with a notification pattern corresponding to the determination result. This makes it easy to identify the gaming machine that has been played, and allows the staff to respond quickly. In addition, the main control board 21b or the like can communicate the determination result to the hall computer 35 to strengthen the hall-side monitoring system and prevent fraud.
In addition, if the gaming machine includes the above-described locking device, each gaming machine can be easily managed on the hall side and the reliability is improved, so that the commercial value of the gaming machine can be increased.
In the present invention, the pachinko gaming machine has been mainly described as an example of the gaming machine.
