Description

  The present invention relates to an attachment mechanism for a gaming machine having a simple structure with a smooth attachment and adjustment of an inclination angle when the gaming machine is attached to an island frame.

  In general, gaming machines such as pachinko machines and slot machines are installed by attaching a rectangular base frame that fits and accommodates them to the island frame. At the time of this installation, either the upper or lower end is used as an island frame. On the other hand, the tilt angle with respect to the gaming machine is adjusted by positioning the front and rear and fixing the other end portion to adjust the front and rear (for example, Patent Document 1).

  In the above prior art invention, the fixing part for fixing the frame (outer frame) to the island frame presses and fixes the frame with the bolts in the vertical direction from above at the upper part of the frame, and the tilt adjustment is performed under the island frame. The base plate placed on the frame is moved back and forth with a screw jack-like slide movement mechanism, and an L-shaped plate is mounted on the base plate at the bottom of the island frame. It is a mechanism for positioning and fixing the frame to adjust the inclination angle.

  However, although the above frame positioning / tilting adjustment mechanism has the advantage that the mechanism is simple and can be procured at low cost, it is difficult to finely adjust the tilt and front / rear position of the frame and the front of the gaming machine with respect to the island frame. Since the L-shaped support plate that receives and supports the lower frame is exposed on the front side of the underframe, there are disadvantages such as complicated installation of a front decorative plate that covers the front frame. In addition, since a large number of sheet metal finishing parts are mounted on the island frame to support the frame, there is a problem that the support of the frame is unstable and vibration noise is severely generated during use.

  The mechanism of the present invention for solving the above-mentioned problem firstly comprises a frame 1 for accommodating and supporting a gaming machine, and an island frame 2 for accommodating the frame 1 and supporting it on the floor side, Fixed bases 7 and 26 attached to the island frame 2 side, movable bases 8 and 27 attached to the fixed bases 7 and 26 so as to be slidable back and forth and connected to either the upper or lower end of the base frame 1 side; Between the fixed bases 7 and 26 and the movable bases 8 and 27, the rail portions 7a and 26a in the front-rear direction and the rail grooves 8a and 27a that are fitted to the rail portions 7a and 26a and slide in the front-rear direction are combined. An adjustment tool including a slide mechanism and a driving unit that slides the movable bases 8 and 27 with respect to the fixed bases 7 and 26 is provided.

  Second, the adjustment tool 4 positions the upper or lower end of the frame 1 and the tilt adjustment tool adjusts the tilt angle of the frame 1 by adjusting the front and rear positions of the other end. It is characterized by consisting of six.

  Thirdly, the drive part of the tilt adjusting tool 6 includes a screw shaft 9 pivotally supported on the front end side of the front side of the fixed base 7 and positions a screw nut 11 that is screwed to the screw shaft 9. The boss portion 8b that is fixedly supported is integrally formed in front of the movable base 8, and the position of the movable base 8 is adjusted to slide back and forth with respect to the fixed base 7 by rotating the screw shaft 9. It is a feature.

  Fourth, a cover 13 that covers the upper portion of the fixed base 7 is attached to the fixed base 7 of the tilt adjuster 6, and the driven gear 12a is axially mounted so as to rotate integrally with the rear side of the screw shaft 9, and the driven gear 12a. A drive gear 12b that meshes with the cover 13 is rotatably supported on the cover 13 side in the vertical axis direction, a drive shaft 16 that rotationally drives the screw shaft 9, and a cylindrical shape that rotatably supports the drive shaft 16 A single shaft case 17 is mounted on the cover 13 so as to protrude.

  Fifth, the mounting bracket 8c including the shaft support portions 8d and 8e for rotatably mounting the connecting portion 18 for releasably locking the locking portion 3a projecting on the rear surface side of the underframe 1 is attached to the tilt adjuster. It is characterized by being integrally formed behind the movable table (8).

  Sixth, a pin case 38 that houses a clamp pin 36 that positions and locks the frame frame 1 with respect to the island frame 2 and a spring 34 that biases the clamp pin 36 in the vertical direction, and moves the pin case 38 up and down.
