Description

  The present invention relates to a gaming machine in which an electronic lock is added to a cylinder lock so that these can be used properly.

  Conventionally, there is a pachinko gaming machine as a representative type of gaming machine. The pachinko gaming machine includes a gaming machine main body to which a gaming board is mounted and a transparent plate holding frame that is disposed on the front surface of the gaming machine main body and is pivotally attached to the gaming machine main body. A cylinder lock is attached so that the frame can be opened only when necessary.

  However, in a pachinko gaming machine equipped with the cylinder lock, for example, in the pachinko hall, each pachinko gaming machine is closely packed with a player and is playing a game. If this occurs, it becomes necessary to open the transparent plate holding frame, and the staff in the hall must interrupt it, insert the key into the keyhole of the cylinder lock, and open the transparent plate holding frame. This is undesirable in terms of service because it interferes with other players. For this reason, there has been a demand for easy unlocking of the cylinder lock using a key.

  On the other hand, recently, remote-operated unlocking means, that is, electronic locks, have been appearing that actuate an actuator by wireless means such as radio waves and infrared rays without using a key. In this electronic lock, for example, the transparent plate holding frame and the main body frame cannot be unlocked in a place where the power cannot be removed, and the transparent plate holding frame cannot be supplied with power after the pachinko machine is installed in the pachinko hall. Even if the main body frame is accidentally closed, there is a problem that the transparent plate holding frame and the main body frame cannot be opened unless the locking device is destroyed from the front side of the pachinko gaming machine.

  In view of these points, for example, as shown in Patent Document 1, a pachinko gaming machine has emerged in which an electronic lock is added to a cylinder lock so that the cylinder lock and the electronic lock can be used properly.

These engaging protrusions 40, 40 engage with the movable plate 35 as the movable plate 35 moves downward, and lower the tip portion against the resilient means. A pair of engaging pieces 42, 42 having an upward claw at the front end of the rear end edge of the fixed plate 34 at the front end and the front end being always urged upward by a resilient means such as a spring It is worn. These engaging pieces 42 are engaged with the movable plate 35 as the movable plate 35 moves upward, and lower the tip portion against the elastic means.

  As shown in FIG. 1, the pair of engagement protrusions 40, 40 are detachably engaged with upper and lower engagement rods 41, 41 provided on one side of the back surface of the transparent plate holding frame 2. The engaging pieces 42, 42 are detachably engaged with a locking rod (not shown) provided on one inner surface of the machine frame 4. Therefore, when the main body frame 5 is closed, the pair of engaging pieces 42 and 42 in the locking device 33 on the main body frame 5 side are engaged with the pair of locking rods of the machine frame 4. When the transparent plate holding frame 2 is closed, the pair of engaging protrusions 40 and 40 in the locking device 33 on the main body frame 5 side engage with the pair of engaging rods 41 and 41 of the transparent plate holding frame 2. ing.

  Therefore, for example, when a key (not shown) is inserted into the key hole 28 of the cylinder lock 24 and rotated in the clockwise direction, the movable plate 35 of the locking device 33 is moved upward, and a pair of engagement pieces 42, 42. And the pair of locking rods on the machine frame 4 side are disengaged, and the main body frame 5 can be opened. On the other hand, when the key inserted into the key hole 28 is rotated in the counterclockwise direction, the movable plate 35 of the locking device 33 is moved down, and the pair of engaging protrusions 40, 40 and the pair on the transparent plate holding frame 2 side are moved. The engagement with the engagement rods 41 and 41 is released, and the transparent plate holding frame 2 can be opened. Even in the electronic lock 38, the same operation as the cylinder lock 24 can be performed by outputting a command from the central control device of the pachinko hall to the electronic lock 38. Incidentally, when the main body frame 5 and the transparent plate holding frame 2 are opened, the engagement protrusions 40 and the engagement pieces 42 are automatically engaged with the engagement rods 41 and the engagement rods by simply pushing them back as they are. Match. In these explanations, the electronic lock 38 is fixed together with the cylinder lock 24. However, when the electronic lock 38 is not used in the pachinko hall, the support plate 24b is attached to the first mounting member 63a as in FIG. The cylinder lock 24 is arranged on the side, a screw (not shown) shorter than the screw rod 67 is inserted into each screw insertion hole 64 and the mounting hole 69, and a nut 70 is screwed to each screw on the front side of the holding piece 68. Tighten. Thereby, the cylinder lock 24 is fixed. Pachinko machines P are almost shipped from the assembly factory in this state.

  By the way, in the pachinko gaming machine P having the cylinder lock 24 and the electronic lock 38 as in the present invention and taking advantage of these advantages, the key cover member to be attached with the key hole 28 exposed to the cylinder lock 24. 44 (44 a) and a key cover member 44 (44 b) having a front side wall 45 that closes the key hole 28. The key cover member 44 will be described in more detail. The key cover member 44 is formed of a synthetic resin material, and there are two types as shown in FIG. One key cover member 44 a is formed in a short cylinder shape whose both end faces are open, and has an outer diameter that is substantially the same as the inner diameter of the insertion hole 26 provided in the main body frame 5. It is formed approximately the same as the diameter. The other key cover member 44b is formed in a short cylinder shape with the front end face completely closed by the front side wall 45 and the rear end face opened. Similarly, the other key cover member 44 b has an outer diameter that is substantially the same as the inner diameter of the insertion hole 26 provided in the main body frame 5, and an inner diameter that is substantially the same as the outer diameter of the cylinder lock 24. ing.

  For example, while the assembly of the pachinko gaming machine P is finished at the assembly factory and placed on the pachinko hall installation island, while the pachinko gaming machine P is removed for replacement or change of the placement location in the pachinko hall, Or, when the pachinko gaming machine P is moved from one pachinko hall in the same group to another pachinko hall, it may be desired to open the transparent plate holding frame 2 using a key. In such a case, it is necessary to make the cylinder lock 24 usable. For this reason, the screw 59 is removed with the main body frame 5 opened, the locking device 33 is removed, and the cylinder lock 24 is removed from the decorative member 22. Next, one key cover member 44a whose both end surfaces are opened is attached to the cylinder lock 24. Then, the locking device 33 is attached to the original position again with the screw 59, and the cylinder lock 24 is inserted into the insertion through hole 26 as shown in FIG. In this state, the key hole 28 of the cylinder lock 24 is exposed to the front surface of the pachinko gaming machine P through the insertion hole 26, and the cylinder lock 24 can be operated by inserting a key into the key hole 28 from the front side of the pachinko gaming machine P. It has become. The other key cover member 44b whose front end face is closed is inserted into the insertion holding hole 46 provided in the lower part on one side of the main body frame 5 as shown in FIG. As shown in FIG. 6, the insertion holding hole 46 is closed at the front end surface and opened at the rear end surface, and the inner diameter thereof substantially coincides with the outer diameter of the key cover members 44a and 44b. The length of the insertion holding hole 46 along the central axis is set slightly longer than the length of the key cover members 44a and 44b in the same direction, and a claw piece 47 facing downward is provided on the upper edge of the rear end edge. Yes. The claw pieces 47 are for preventing the key cover members 44a and 44b inserted into the insertion holding holes 46 from coming out and dropping unnecessarily.

  On the other hand, for example, when the electronic lock 38 is added to the pachinko gaming machine P provided with the cylinder lock 24 in the pachinko hall and only the electronic lock 38 is used, both the cylinder lock 24 and the electronic lock 38 are used in the pachinko hall. In the case of using only the electronic lock 38 in the pachinko gaming machine P in which is arranged, it is necessary to keep the cylinder lock 24 unusable in order to prevent mischief and illegal acts. For this reason, for each pachinko gaming machine P, with the main body frame 5 opened, the screws 59 are removed, and the cylinder lock 24 of the locking device 33 is removed from the decorative member 22. Then, one key cover member 44a whose both end faces that have been attached to the tip of the cylinder lock 24 are opened is removed. Then, the other key cover member 44 b whose front end face is closed is attached to the tip of the cylinder lock 24. Then, the locking device 33 is attached to the original position again with the screw 59, and the cylinder lock 24 is inserted into the insertion through hole 26 as shown in FIG. In this state, the key hole 28 of the cylinder lock 24 is blocked by the front side wall 45, and it becomes impossible to operate the cylinder lock 24 by inserting the key into the key hole 28 from the front side of the pachinko gaming machine P as it is. Incidentally, the one key cover member 44a with both end surfaces opened is inserted into the insertion holding hole 46 provided at the lower part on one side of the main body frame 5 and stored.

  In order to replace the key cover member 44, the screw rods 67 and 67 for assembling the cylinder lock 24 and the electronic lock 38 to the locking device 33 are removed without removing the locking device 33 as described above, and the cylinder lock 24 and the electronic lock are removed. 38 may be removed and the key cover member 44 may be replaced.

  As a result, in the pachinko hall, the cylinder lock 24 can be switched to the electronic lock 38. For example, in order to solve the trouble caused by the clogging of balls during business, the pachinko gaming machine P in which trouble has occurred Then, the electronic lock 38 is electrically operated to open the transparent plate holding frame 2 and a pachinko hall attendant deals with it. In addition, when cleaning all the pachinko gaming machines P after business, the transparent plate holding frame 2 can be opened for all the pachinko gaming machines P by electrically operating all the electronic locks 38, The cleaning can be performed smoothly. On the other hand, the cylinder lock 24 is attached by the other key cover member 44b, and the front keyhole 28 is closed, so that a foreign object such as a toothpick can be inserted into the keyhole 28 of the cylinder lock 24 or the cylinder lock 24 can be inserted.
