  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

  1 to 5 show a power supply apparatus according to an embodiment of the present invention. 1 is an external perspective view of the power supply device 1. FIG. 2 is a side view of the power supply device 1 on the right side, and a cross-sectional view of the right side AA 'on the left side (hereinafter, this direction is referred to as the front direction). ). 3 is an exploded perspective view from the front right side, and FIG. 4 is an exploded perspective view from the front left side. FIG. 5 is a side sectional view of the door lock mechanism 13.

  The power supply device 1 includes a circuit board (not shown) on which a circuit for supplying power to the device units of each part of a game table represented by a so-called pachislot table is mounted, and includes a case 11 for housing it. . Further, a cover door 12 is provided in the front direction of the power supply device 1, and the operation panel 41 is exposed when rotated in the direction of arrow O in FIG. 41 is coated.

  Further, the operation panel 41 includes a power switch 51 including a seesaw switch that allows switching of power ON / OFF, a hitting presence / absence setting switch 52 including a slide switch that allows switching of whether or not the game table is stopped, In order to collect medals at the time of maintenance, a medal collection switch 53 consisting of a slide switch that allows switching whether or not the medals are automatically paid out to the tray of the game stand, a key is inserted, for example, clockwise or counterclockwise Setting switches 54 each including a key-type switch that is mounted on a circuit board via a harness (not shown) are provided by allowing rotation of the game stand to change the setting of the game play rate.

  When the cover door 12 is closed, the operation panel 41 is covered so that the power switch 51, the hitting / non-stop setting switch 52, the medal recovery switch 53, and the setting switch 54 are not tampered with.

  On the upper left and right sides of the front side of the cover door 12, hinges 63-1 and 63-2 having substantially cylindrical rod shapes are provided, and the lower part 63b and the hinge 63-2 of the hinge 63-1 are respectively attached to the main body of the power supply device 1. The door opening / closing support portions 55-1 and 55-2 having substantially the same diameter as the hinges 63-1 and 63-2 are inserted. With such a configuration, the cover door 12 is configured to be rotatable about the hinges 63-1 and 63-2.

  Further, the upper part 63 a of the hinge 63-1 is inserted through the helical torsion coil spring 71. The torsion coil spring 71 has one end fixed to the spring receiving portion 56 and the other end fixed to the spring receiving portion 62. The torsion coil spring 71 generates a torque that biases the cover door 12 in the direction of arrow C in FIG. For this reason, the cover door 12 is closed so as to cover the operation panel 41 as shown in FIGS. 1 and 2 when no load is applied due to the torque generated by the torsion coil spring 71. The panel 41 is also covered. On the other hand, the arrow 14 shown in FIG. 1 is applied while a knob 14a is picked by the user at the lower part of the door lock cover part 14 provided at the right front portion and a load is applied to overcome the torque generated by the torsion coil spring 71 described above. By being pulled out in the O direction, the cover door 12 is rotated and opened about the hinges 63-1 and 63-2, the operation panel 41 is exposed, the power switch 51 on the operation panel 41, and whether or not to hit The switch 52, the medal recovery switch 53, and the setting switch 54 are operable.

  The door lock mechanism 13 includes a housing 31, a compression coil spring 32, operation guides 33-1 and 33-2, and a side part of the case 11, and a table 34 provided at the front right end of the operation panel 41. ing.

  The operation guide 33-1, the compression coil spring 32, and the operation guide 33-2 are sandwiched between the housing 31 and the base 34 while being inserted into the recess 31c of the housing 31 from above in this order.

  More specifically, the operation guides 33-1 and 33-2 abut the retaining pieces 33c-1 and 33c-2 against both ends of the compression coil spring 32, respectively, and the column portions 33d-1 and 33d. -2 is inserted into the recess 31c of the housing 31 together with the compression coil spring 32, and is sandwiched between the housing 31 and the base 34 in a state of being slidable in the recess 31c.

  Since the compression coil spring 32 generates a repulsive force in the directions of arrows A and A ′ shown in FIG. 5, the retaining pieces 33 c-1 and 33 c-2 are pressed against the arrows A and A ′, respectively. Although it is in a state, it is fixed in the housing 31 by contacting the step portions 31b-1 and 31b-2 in the housing 31. Accordingly, when the operation guides 33-1 and 33-2 are unloaded, the retaining pieces 33c-1 and 33c-2 are biased toward the step portions 31b-1 and 31b-2 from the directions of the arrows A and A ′. It is stationary with the Further, the retaining pieces 33c-1 and 33c-2 have a substantially elliptical horizontal cross-sectional shape on the sliding surface between the recess 31c of the housing 31 and the base 34, and are non-circular. −1, 33b-2 cannot be rotated about the pillars 33d-1, 33d-2 as axes.

  The operation guides 33-1 and 33-2 have predetermined distances (the operation surfaces 33a-1 and 33a-2 can be picked by at least two fingers of an average human hand, respectively). For example, the distance between the index finger and the thumb can be grasped), and the user can grasp both in the directions of arrows B and B ′ in FIG. 5 so as to overcome the repulsive force of the compression coil spring 32. When pressed, the pillars 33d-1, 33d-2 slide on the sliding surfaces formed by the recess 31c and the base 34 of the housing 31, respectively, and the retaining pieces 33c-1, 33c-2 When it comes into contact with the operation restricting protrusions 31a-1 and 31a-2, it stops.

  That is, if the operation guides 33-1 and 33-2 are urged by the repulsive force of the compression coil spring 32 and are not loaded, the retaining pieces 33c-1 and 33c-2 are respectively connected to the step portions 31b-1 and 31b-1. Although it is stationary by contacting 31b-2, when the operation surfaces 33a-1 and 33a-2 are pressed and the repulsive force of the compression coil spring 32 is overcome, the retaining pieces 33c-1 and 33c-2 are respectively removed. The column portions 33d-1 and 33d-2 are slid in the directions of arrows B and B 'within a range until they come into contact with the operation limiting protrusions 31a-1 and 31a-2. In other words, the operation limiting protrusions 31a-1, 31a-2 and the step portions 31b-1, 31b-2 restrict the slidable ranges of the operation guides 33-1, 33-2, respectively. Note that the operation guides 33-1 and 33-2 can slide independently of each other.

  Further, the operation guides 33-1 and 33-2 face the back surface of the cover door 12 when the cover door 12 is closed at the end where the operation surfaces 33a-1 and 33a-2 are provided. The engaging claws 33b-1 and 33b-2 are provided. The engaging claws 33b-1 and 33b-2 are configured to engage with the engaging pieces 61-1 and 61-2 provided on the door lock cover portion 14, respectively. More specifically, the engaging claws 33b-1 and 33b-2 include key portions 33e-1 and 33e-2, respectively, and conversely, the engaging pieces 61-1 and 61-2 are connected to the cover door 12. In the closed state, each has a key-like configuration with respect to the upper direction on the back side. That is, as shown in FIG. 5, the end portions 61 a-1 and 61 a-2 of the engagement pieces 61-1 and 61-2 protrude toward the back surface with respect to the surface of the operation panel 41, and reversely In addition, the curved surfaces 33b′-1 and 33b′-2 of the engaging claws 33b-1 and 33b-2 protrude from the surface of the operation panel 41 in the front direction. Further, the end portions 61a-1, 61a-2 of the engaging pieces 61-1, 61-2 and the curved surfaces 33b'-1, 33b'-2 of the engaging claws 33b-1, 33b-2 are respectively in the vertical direction. Since the end portions 61a-1, 61a-2 and the curved surfaces 33b'-1, 33b'-2 (key portions 33e-1, 33e-2) are engaged with each other, the cover is thereby covered. The door 12 is locked with respect to the main body 11.

  Next, an operation when the cover door 12 is closed with respect to the main body of the power supply device 1 will be described.

  When the cover door 12 is in an open state, when the load on the cover door 12 in the direction of arrow O in FIG. 1 by the user is released, that is, when the cover door 12 is not touching anything. The cover door 12 is rotated in the direction of arrow C in FIG. 1 by the torque generated by the torsion coil spring 71, and the cover door 12 closes the case 11 of the power supply device 1 to cover the operation panel 41. .

  Then, when the rotation of the cover door 12 in the direction of arrow C proceeds, the engagement pieces 61-1 and 61-2 of the door lock cover portion 14 immediately before the cover door 12 is closed with respect to the case 11 of the power supply device 1. End surfaces 61a-1, 61a-2, and curved surfaces 33b'-1, 33b'-2 of the engaging claws 33b-1, 33b-2 of the operation guides 33-1, 33-2 of the door lock mechanism 13. Are in contact with each other. However, even in this state, the cover door 12 is rotated in the direction of arrow C by the torque of the coil spring 71 to be twisted.

  Then, the end portions 61a-1 and 61a-2 of the engagement pieces 61-1 and 61-2 of the door lock cover portion 14 are engaged with the engagement claws 33b-1 and 33b- of the operation guides 33-1 and 33-2. The curved surfaces 33b'-1 and 33b'-2 in Fig. 2 are pressed in the directions of arrows B and B ', respectively. When the curved surfaces 33b'-1 and 33b'-2 of the operation guides 33-1 and 33-2 are pressed in the directions of arrows B and B ', respectively, the column portions 33d-1 and 33d-2 are changed to arrows B and B, respectively. Slide in the B ′ direction. As the pillar portions 33d-1 and 33d-2 slide in the directions of arrows B and B ', the retaining pieces 33c-1 and 33c-2 sandwich the compression coil spring 32 from the directions of arrows B and B'. Press.

  The compression coil spring 32 is not provided with a repulsive force that is greater than the force generated by the pressing action of the retaining pieces 33c-1 and 33c-2 based on the rotation of the cover door 12 in the arrow C direction. The sliding of −1, 33d-2 in the directions of arrows B and B ′ proceeds.

  The end portions 61 a-1 and 61 a-2 of the engagement pieces 61-1 and 61-2 of the door lock cover portion 14 are operated as the operation guides 33-1 and 33-3 as the cover door 12 rotates in the direction of arrow C. The curved surfaces 33b'-1 and 33b'-2 of the engaging claws 33b-1 and 33b-2 of 33-2 are continuously pressed in the directions of arrows B and B '. Then, the curved surface 33b'-1 operates so as to slide into the lower portion of the end portion 61a-1, and the curved surface 33b'-2 slides into the upper portion of the end portion 61a-2.

  For this reason, when the uppermost part of the curved surface 33b′-1 gets over the lowermost part of the end part 61a-1, the retaining piece 33c-1 receives the repulsive action of the compression coil spring 32, so that the column part 33d-1 is moved to the arrow A. When the key portion 33e-1 engages with the engagement piece 61-1, the engagement piece 61-1 and the engagement claw 33b-1 are engaged with each other. Similarly, when the lowermost portion of the curved surface 33b′-2 gets over the uppermost portion of the end portion 61a-2, the retaining piece 33c-2 receives the repulsive action of the compression coil spring 32, so that the column portion 33d-2 is moved to the arrow A. By sliding in the 'direction and the key portion 33e-2 is engaged with the engagement piece 61-2, the engagement piece 61-1 and the engagement claw 33b-1 are engaged.

  As a result, as shown in the right part of FIG. 6, the engaging claws 33b-1 and 33b-2 are moved in the directions of arrows B and B ′ by the action that occurs when the cover door 12 is closed in the direction of arrow C, respectively. After sliding, the state shifts to the left part of FIG. 6 and engages with the engagement pieces 61-1 and 61-2.

  For this reason, when the cover door 12 is closed, the engaging claws 33b-1, 33b-2 and the engaging piece 61- are caused by the torque generated by the torsion coil spring 71, even if the user does not perform any operation. 1 and 61-2 are engaged with each other, the cover door 12 is locked only by releasing the hand.

  The cover door 12 is restrained with respect to the case 11 of the power supply device 1 by engaging the engaging claws 33b-1 and 33b-2 and the engaging pieces 61-1 and 61-2. Therefore, even if the knob 14a of the door lock cover portion 14 is simply pulled in the direction of the arrow O, it cannot be rotated (the cover door 12 cannot be opened), and therefore cannot be easily opened. It becomes a state.

  Further, as described above, the retaining pieces 33c-1 and 33c-2 have a substantially oval shape in the horizontal sectional shape on the sliding surface between the recess 31c of the housing 31 and the base 34, and are non-circular. Even if the engaging claws 33b-1 and 33b-2 are illegally hooked with a tool (wire or the like), the engaging claws 33b-1 and 33b-2 have the pillar portions 33d-1 and 33d-2 as axes. Since it does not rotate, it is difficult to release the engagement between the engagement claws 33b-1 and 33b-2 and the engagement pieces 61-1 and 61-2. It can be suppressed.

  Next, an operation when the cover door 12 is opened with respect to the main body of the power supply device 1 will be described.

  As described above, the cover door 12 rotates in the direction of the arrow O when the engaging claws 33b-1 and 33b-2 are engaged with the engaging pieces 61-1 and 61-2. I can't. Therefore, in order to release this engaged state, as shown in FIGS. 7 and 8, the operation surfaces 33 a-1 and 33 a-2 are grasped with two fingers and pressed in the directions of arrows B and B ′. . By this operation, the pillar portions 33d-1 and 33d-2 slide in the directions of arrows B and B ', and are loaded on the operation surfaces 33a-1 and 33a-2 to the retaining pieces 33c-1 and 33c-2. As a result, the retaining pieces 33c-1 and 33c-2 compress the compression coil spring 32 so as to sandwich the compression coil spring 32 from the directions of arrows B and B ′.

  FIG. 7 shows a state where the operation surfaces 33a-1 and 33a-2 are pressed by the index finger and the thumb. FIG. 8 shows an enlarged view of the door lock mechanism 13 in FIG.

  When the pressing force in the directions of arrows B and B ′ is further applied to the operation surfaces 33a-1 and 33a-2 so as to overcome the repulsive force generated by the compression coil spring 32 from this state, the column portion 33d-1 , 33d-2 slide in the directions of arrows B and B ', and the key portions 33e-1 and 33e-2 are released from the state of being engaged with the engaging pieces 61-1 and 61-2. . In this way, the engagement claws 33b-1 and 33b-2 are released from the state in which the key portions 33e-1 and 33e-2 are engaged with the engagement pieces 61-1 and 61-2. Then, the engagement with the engagement pieces 61-1 and 61-2 is released, and the cover door 12 is released from the restraint by the case 11. However, even in this state, the cover door 12 is urged in the direction of the arrow C by the torque generated by the torsion coil spring 71, so that the cover door 12 is, for example, a knob 14 a of the door lock cover portion 14. The case 11 cannot be opened unless it is further pulled out in the direction of the arrow O.

  As described above, in order to open the cover door 12, the operation surfaces 33 a-1 and 33 a-2 are pressed against the directions of the arrows B and B ′, and at the same time, the key portions 33 e-1 and 33 e-2 are It is necessary to release from the state of being engaged with the engaging pieces 61-1 and 61-2. With the above-described configuration, the keys 33e-1 and 33e-2 are released from the state of being engaged with the engagement pieces 61-1 and 61-2, respectively, with at least two fingers. Operation is required.

  Further, since the cover door 12 is biased in the direction of arrow C by the torque generated by the torsion coil spring 71, it must be pulled out in the direction of arrow O by the knob 14a or the like.

  With the above-described configuration, in the power supply device 1 described above, the cover door 12 needs to grip the operation surfaces 33a-1 and 33a-2 with at least two fingers and pull out the knob 14a with at least one other finger. Furthermore, it is necessary to execute each operation at a different position (at a position that is not far enough to be operated with one hand). At this time, the operation directions of the operation surfaces 33a-1 and 33a-2 are perpendicular to the rotation direction of the cover door 12, and are independent operations. Therefore, at least two actions or more (a first action of picking the operation surfaces 33a-1 and 33a-2 with at least two fingers and a second action of pulling the pick 14a with at least another finger) If not operated, the cover door 12 cannot be opened from the case 11. For this reason, even if the front door of the gaming table can be slightly opened illegally, it is practically difficult to open the cover door 12, so that the cover door 12 is prevented from being opened illegally. Is possible.

  As a result, even if the front door of the game table can be opened even by a slight tool (wire or the like), the cover door 12 of the power supply device 1 is further opened, and the power supply on the operation panel 41 is then opened.
