  FIG. 1 is a perspective view showing the main part of the appearance of the slot machine. This slot machine is configured, for example, as shown in FIG. That is, as shown in FIG. 1, in the slot machine 1, the front opening of the housing 3 is closed by the front panel 5 so that it can be opened and closed, and the operation plate 7 is disposed at a substantially central height position of the front panel 5. In addition, a front plate 9 is disposed above the operation plate 7.

  Three symbol display windows 11 are arranged side by side on the front plate 9, and symbols of a rotating reel (not shown) provided in the housing 3 can be visually recognized from each symbol display window 11. Further, the operation panel 7 has a bet switch 15 for reducing the number of credited medals and replacing it with a medal insertion, a start switch 17 for starting the rotation of each rotary reel, and stopping the rotation of each rotary reel. There are provided a stop switch 19, a medal slot 21, and a settlement switch 23 for paying out stored medals. Further, although not shown in the figure, there are a motor for rotating each rotary reel, a hopper unit for paying out game medals, a power supply box, a control board for controlling games, etc. Built in.

  The left and right side plates 31 of the housing 3 are respectively provided with handle holes 33 penetrating the side plates 31 so as to be easily lifted when the slot machine 1 is transported. The handle hole 33 has a horizontally long, substantially rectangular shape that is formed slightly above the center of the side plate 31 in the height direction. A handle hole cover described below is attached to the handle hole 33. In FIG. 1, the handle hole cover is not shown for convenience of explanation.

  FIG. 2 is a perspective view of a handle hole cover according to an embodiment of the present invention as viewed obliquely from below, and FIG. 3 is a perspective view of the handle hole cover as viewed obliquely from above. 4 to 6 are views showing the handle hole cover, FIG. 4 is a plan view, FIG. 5 is a bottom view, and FIG. 6 is a left side view. For convenience of explanation, FIG. 6 is shown enlarged compared to FIGS. 4 and 5.

  The handle hole cover 35 is integrally formed of a synthetic resin (for example, polypropylene), and extends to the opening of the cover main body 50 and the substantially rectangular tube-shaped cover main body 50 with the back 51 closed. A short square tubular insertion part 60 and a flange part 70 provided at the opening end of the insertion part 60 are provided. Here, the cross-sectional outer shape of the cover main body 50 and the fitting insertion portion 60 is substantially the same shape as the handle hole 33, that is, a horizontally long substantially rectangular shape.

  Further, as shown in FIG. 6, the cover main body 50 is formed so as to be inclined such that the upper surface 501 and the lower surface 502 are substantially parallel and the back portion 51 side (left side in the drawing) is higher. It is almost a parallelogram. On the other hand, the upper surface 601 of the insertion portion 60 is formed horizontally, and the lower surface 602 has the same inclination as the lower surface 502 of the cover main body 50 is extended as it is. As a result, strictly speaking, the outer shape of the fitting insertion portion 60 is a quadrangular frustum shape, the axis L1 of the fitting insertion portion 60 is almost horizontal, and the axis L2 of the cover main body portion 50 is on the back 51 side. (Left side in the figure) is upward from the axis L1 of the insertion portion 60.

  As shown in FIG. 5, movable portions 61 are provided on the lower surface 602 of the insertion portion 60 at positions close to the left and right ends in the drawing. As shown in FIG. 6, the movable portion 61 includes a base 611 extending to the fitting insertion portion 60, an elastic rod-shaped movable body 612, and a movable body 612 that swings at approximately the center in the left-right direction in the drawing. And a connecting portion 613 that is movably supported. Further, a hook 614 is formed at the tip of the movable body 612 located on the cover main body 50 side. The handle hole cover 35 is integrally formed of a synthetic resin. For this reason, the connecting portion 613 has flexibility, and the connecting portion 613 biases and supports the movable body 612 by the flexibility. That is, when the handle hole cover 35 is a single body, the connecting portion 613 biases the movable body 612 so that the hook 614 approaches the lower surface of the cover main body portion 50, and the movable body 612 includes the cover main body portion 50. It faces in a direction substantially parallel to the axis L2.

  Further, as shown in FIG. 5, guide protrusions 62 are respectively provided on the lower surface 502 of the cover main body 50 on the back side (upward in the figure) in the insertion direction of the movable portion 61. As shown in FIGS. 2 and 5, the guide protrusion 62 is formed in a U shape in plan view. Further, the guide projection 62 is provided so as to be inclined from the back side of the cover main body 50 toward the front side (from the left side to the right side in FIG. 2). The guide protrusion 62 can guide the insertion of the cover main body 50 into the handle hole 33, and when the cover main body 50 is inserted into the handle hole 33, the movable portion is prevented from colliding with the side plate 31. 61 can be protected.

  Also, as shown in FIGS. 2 and 5, a plurality of thin plate-like inclined protrusions 63 (five in this embodiment) are provided between the movable parts 61 at both ends. The inclined protrusion 63 is long in the insertion direction of the cover main body 50 into the handle hole 33 (vertical direction in FIG. 5), and is provided from the lower surface 502 of the cover main body 50 to the lower surface 602 of the fitting insertion portion 60. ing. A guide portion 631, which is a portion corresponding to the lower surface 502 of the cover main body portion 50, of the inclined protrusion 63 is formed to have substantially the same inclination as the guide protrusion 62 in a side view. Further, the contact portion 632 corresponding to the lower surface 602 of the fitting insertion portion 60 in the inclined protrusion 63 has a surface substantially parallel to the upper surface 601 of the fitting insertion portion 60 as shown in FIG. Is formed.

  Further, as shown in FIGS. 4 and 6, a retaining protrusion 52 is provided on the upper surface 501 of the cover main body 50 along the boundary with the upper surface 601 of the fitting insertion portion 60. The retaining projection 52 is formed long in the width direction (left and right direction in FIG. 4) of the handle hole cover 35, and stands upright with respect to the upper surface 601 of the fitting insertion portion 60 as shown in FIG. As shown, it is formed in a triangular shape in side view. Thus, in this embodiment, the contact portion 632 of the inclined protrusion 63 corresponds to the “contact protrusion” of the present invention.

  Next, attachment of the handle hole cover 35 to the handle hole 33 will be described. FIG. 7 is a partial cross-sectional view of the side plate 31 of the housing 3, and FIG. 8 is a partial cross-sectional view showing a state where the handle hole cover 35 is attached to the handle hole 33.

  When the cover main body 50 of the handle hole cover 35 is inserted into the handle hole 33 from the outside of the housing 3 (on the right side in FIGS. 7 and 8), the upper surface 501 and the lower surface 502 of the cover main body 50 become the inner periphery of the handle hole 33. Insertion is guided while being in sliding contact with the surface 331. Next, the insertion is further guided while the guide portion 631 and the guide protrusion 62 of the inclined protrusion 63 are in sliding contact with the inner peripheral surface 331 of the handle hole 33. Further, the insertion is guided while the contact portion 632 and the movable body 612 of the inclined protrusion 63 are in sliding contact with the inner peripheral surface 331. At this time, since the movable body 612 has elasticity and is slidably contacted with the inner peripheral surface 331 while being bent, for example, the movable body 612 does not hinder insertion into the handle hole 33. Further, since the connecting portion 613 biases the movable body 612 so that the hook 614 approaches the lower surface 502 of the cover main body portion 50, the hook 614 prevents the fitting insertion portion 60 from being inserted into the handle hole 33. There is nothing.

  When the fitting insertion portion 60 is fitted into the inner peripheral surface 331 of the handle hole 33, the retaining projection 52 is locked to the inner side surface 311 of the casing 3 on the upper peripheral edge of the handle hole 33, and the movable body. 612 is pushed by the inner peripheral surface 331 of the handle hole 33 and swings against the urging force, and the hook 614 engages with the inner side surface 311 of the casing 3 at the lower peripheral edge of the handle hole 33. Here, since the movable body 612 is pressed by the inner peripheral surface 331 of the handle hole 33, the hook 614 is reliably locked. Furthermore, the flange portion 70 comes into contact with a flange fitting insertion recess 312 a provided on the outer surface 312 of the casing 3 at the periphery of the handle hole 33. As a result, the handle hole cover 35 is securely fixed to the housing 3.

  Thus, according to this embodiment, the connecting portion 613 provided on the lower surface 602 of the fitting insertion portion 60, the hook 614 formed on the tip of the movable body 612 located on the cover body portion 50 side, and the connecting portion And a movable body 612 that is urged by 613 in a direction in which the hook 614 approaches the lower surface 502 of the cover main body 50 and is swingably supported, and the fitting insertion portion of the handle hole 33 to the inner peripheral surface 331 60, the movable body 612 swings and the hook 614 is locked to the inner surface 311 of the casing 3 at the periphery of the handle hole 33, and the flange portion 70 is positioned at the periphery of the handle hole 33. Therefore, the handle hole cover 35 can be securely attached to the handle hole 33 of the housing 3 by the locking by the hook 614 and the contact by the flange portion 70. Further, since another fixing member such as a screw is not used, it is only necessary to insert the cover main body portion 50 into the handle hole 33 and fit the fitting insertion portion 60 into the handle hole 33. Workability can be greatly improved.

  Further, according to this embodiment, since the rectangular tubular cover main body portion 50 with the back portion 51 closed is used and the flange portion 70 is inserted into the recess 312a of the handle hole 33, the housing 3 The handle hole 33 penetrating through the side plate 31 can be almost sealed, and an illegal so-called got action performed by inserting a foreign substance into the housing 3 from the outside can be surely prevented.

  Further, according to this embodiment, since the movable body 612 made of synthetic resin has elasticity, it is possible to prevent the movable body 612 from interfering with the insertion into the handle hole 33. Further, since the connecting portion 613, the movable body 612, the base portion 611, and the fitting insertion portion 60 are integrally formed of synthetic resin, it has flexibility, and the movable body 612 is urged by the flexibility. Thus, the connecting portion 613 supported can be easily realized with a simple configuration. Further, since the connecting portion 613 urges the movable body 612 so that the hook 614 approaches the lower surface 502 of the cover main body 50, the hook 614 prevents the cover main body 50 from being inserted into the handle hole 33. Can be reliably prevented.

  Further, according to this embodiment, the inclined protrusion 63 is provided along the movable portion 61 from the lower surface 502 of the cover main body portion 50 to the lower surface 602 of the fitting insertion portion 60. Since the abutting portion 632 corresponding to the lower surface 602 of the insertion portion 60 abuts on the inner peripheral surface 331 by fitting the fitting insertion portion 60 into the inner peripheral surface 331 of the handle hole 33, the movable body 612. Since an average force is applied to the contact portion 632, a situation in which an excessive force is applied only to the movable body 612 and the movable body 612 is damaged can be avoided.

  Further, according to this embodiment, the guide protrusion 62 for guiding the insertion of the cover main body 50 into the handle hole 33 is provided on the back side of the lower surface 502 of the cover main body 50 in the insertion direction of the movable body 612. Therefore, the cover body 50 can be smoothly inserted into the handle hole 33. Further, the guide protrusion 62 can prevent the movable body 612 from colliding with the inner peripheral surface 331 of the handle hole 33 and being damaged.

  Further, according to this embodiment, the upper end 51 a of the back portion 51 of the cover main body portion 50 is more than the upper surface 601 of the insertion portion 60 in a state where the insertion portion 60 is fitted to the inner peripheral surface 331 of the handle hole 33. Since it is located above, when the hand is inserted into the handle hole cover 35 so as to carry the housing 3, the fingertip faces upward at the back portion 51 of the cover main body portion 50 with respect to the fitting insertion portion 60. Can be carried easily.

  The present invention is not limited to the above embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention. For example, the handle hole cover 35 shown in FIGS. 9 and 10 may be used. FIG. 9 is a left side view showing another embodiment of the handle hole cover, and FIG. 10 is a partial sectional view showing a state in which the handle hole cover of FIG. 9 is attached to the handle hole. In FIG. 9 and FIG. 10, the same code | symbol is attached | subjected to the same component as the said embodiment.

  In this embodiment, the upper surface 501 of the cover main body 50 is substantially horizontal, that is, substantially parallel to the central axis L3 of the handle hole 33, and the lower surface 502 of the cover main body 50 is closer to the central axis L3 on the back side 51 side. Inclined in the direction. Further, the upper surface 601 of the fitting insertion portion 60 is substantially horizontal and extends on the upper surface 501 so as to form substantially the same surface as the upper surface 501 of the cover main body portion 50. Further, the lower surface 602 of the insertion portion 60 is inclined in a direction in which the cover main body 50 side approaches the central axis L3, and is extended to the lower surface 502 so as to form substantially the same surface as the lower surface 502 of the cover main body 50. ing. Thus, in this embodiment, the lower surface 602 of the insertion portion 60 corresponds to the “locking side surface” of the present invention, and the upper surface 601 of the insertion portion 60 corresponds to the “opposite surface of the locking side surface” of the present invention. .

  The procedure for attaching the handle hole cover 35 to the handle hole 33 shown in FIGS. 9 and 10 is exactly the same as that of the above embodiment. In this embodiment, the handle hole cover 35 is securely attached to the handle hole 33 of the housing 3. It can be attached, and it is possible to achieve the same effects as in the above-described embodiment, for example, the workability of attachment to the handle hole 33 can be greatly improved. However, in this embodiment, the upper surface 501 of the cover main body 50 is substantially horizontal from the upper surface 601 of the fitting insertion portion 60, and even if the hand is inserted into the handle hole cover 35 to carry the housing 3, the fingertip is not inserted into the fitting insertion portion 60. On the other hand, since it does not face upward at the back part 51 of the cover main body part 50, the above embodiment can be performed more easily for carrying the housing 3. In this embodiment, the guide protrusion 62 is formed on the lower surface 502 of the cover main body 50 (see FIGS. 9 and 10). However, the guide protrusion 62 is not particularly necessary and may be deleted. I do not care.

  In the above embodiment, the movable body 612 is provided on the lower surface 602 of the fitting insertion portion 60 and the retaining projection 52 is disposed on the upper surface 501 of the cover main body 50. However, the movable body 612 and the retaining projection are provided. The position where 52 is provided is not limited to this. For example, the movable body 612 may be provided on the upper surface 601 of the fitting insertion portion 60, and the retaining projection 52 may be provided on the lower surface 502 of the cover main body portion 50. Alternatively, they may be provided on other surfaces such as the left and right surfaces. However, considering the fixing force by locking, it is preferable to provide the movable body 612 and the retaining protrusion 52 on the surfaces facing each other. The positions where the movable body 612 and the retaining protrusion 52 are provided are the same in the configurations shown in FIGS.

  Moreover, in the said embodiment, although the handle hole 33 is made into the substantially rectangular shape, it is not restricted to this, Another shape may be sufficient. In this case, the cross-sectional outer shapes of the cover main body 50 and the fitting insertion portion 60 may be formed in substantially the same shape according to the shape of the handle hole 33.
