Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prize ball tray provided on the front of a pachinko machine for receiving a prize ball released when a prize ball enters.

[Prior Art] In the case of a so-called motor-driven pachinko machine equipped with an automatic hit ball launching device, two prize balls are provided on the upper and lower sides, and the released prize balls are first referred to as upper prize balls, that is, generally referred to as upper plates. The ball is received by the prize ball tray, which is then guided to the hitting ball supply device and sent to the firing position one by one so that continuous automatic firing can be performed. When there is a released prize ball exceeding the number of fired balls, this tray is received. At the same time, the overflowing prize balls are guided to the lower prize ball receiver, that is, the lower plate through the overflow passage, and are stored therein. When the prize balls guided to the lower plate are taken out, they are scraped out by hand and transferred to a ball box, or are taken out through a ball hole formed in the bottom of the lower plate.

At present, most pachinko machines usually have a ball hole in the bottom of the lower plate, that is, the bottom of the prize ball tray below, and in normal times this ball hole is closed by a shutter biased by a spring and the ball is closed. The spill is prevented, and the shutter is pushed open against the biased spring when removing.

The bias by this spring is to prevent the ball from falling due to forgetting to tighten, and it is automatically closed in normal times, so that forgetting to tighten is avoided, but it is always urged in the closing direction. There was an inconvenience that the shutter had to be held down by hand to prevent the shutter from closing when hitting the ball. In particular, the fulfillment of certain prize conditions relaxes the prize conditions for a certain period of time, so that pachinko machines and the like that are set so that a large amount of prize balls are continuously released, continue withdrawing work to the ball box and continuing the game. The task of opening the shutters is very cumbersome, since it is often necessary to perform the operations simultaneously.

[Problems to be Solved by the Invention] In view of such inconvenience, recently, a shutter that has been opened with stopper means provided on the prize ball receiving tray is locked.
A prize ball saucer having a structure that does not arbitrarily close even when the hand is released has been proposed and put into practical use.

However, the prize ball tray provided with the stopper means leaves the shutter open unless the locked state is released after the removal, and there is a problem that the prize ball is sowed if used without knowing this.

[Means for Solving the Problems] The present invention has been researched and developed in order to solve the problems in the prize ball saucer provided with such stopper means. The ball box used when extracting the prize ball stored in the ball saucer is associated with the stopper means provided on the prize ball saucer, and the stopper means is used only when the ball box faces the prize ball saucer for extracting the prize ball. By exerting the engagement function, the shutter can be maintained in the open state, and when the ball box is removed, the engagement function is released so that the shutter is not opened in the state where the ball box is not present. The company will provide a prize ball saucer for pachinko machines.

The present invention will be described in further detail.In a winning tray of a pachinko machine in which a ball punching hole provided in a bottom portion is closed with a shutter biased by a spring to prevent a prize ball to be stored from falling, a ball receiving hole is provided below a prize ball tray. When the shutter is in the open state, stopper means are provided corresponding to the position of the locking part provided on the shutter, and the stopper means is always kept apart from the locking part by a spring force or its own weight. A prize ball in which the ball box presses the stopper means when the ball box faces downwardly of the ball punching hole, thereby enabling the engagement with the locking portion of the shutter to hold the shutter open. It is to provide a saucer.

In the present invention, the shutter may be configured to slide along the bottom of the prize ball receiving tray as long as the shutter is always urged in the closing direction by a spring to close the ball hole, and the slide is guided by a guide and linearly moved. Even if it slides,
Further, the opening may be opened and closed by sliding so as to rotate in a spiral shape around one point.

On the other hand, it is appropriate that the stopper means is provided at a position where it engages with the edge of the ball box when the ball box faces below the winning ball tray, and retreats from the sliding range of the shutter which normally slides. Engagement with the engaging portion provided in this is avoided, and the ball box is inserted under the winning ball tray and positioned below the ball hole, so that the engagement with the engaging portion is enabled. Is set.

Preferably, the stopper means is such that a member that engages with the engaging portion of the shutter projects forward from under the winning ball saucer, and can be disengaged by a fingertip. It is desired that after the completion of the process, the device returns to the original state and automatically returns to the engageable state.

[Operation] In the prize ball tray of the present invention, the shutter is normally closed by the bias of the spring, and the ball hole is closed to prevent the prize ball from spilling. This shutter opens when the slider is slid against the bias of the spring, and the prize ball inside the dish can be removed in the same way as the conventional prize ball saucer with a shutter. When the hand is released, it is automatically closed by the spring. Will do. On the other hand, insert a ball box under the prize bowl to remove the ball,
When the stopper means is pressed with the ball box, the locking portion provided on the shutter and the stopper means can be engaged. As a result, when the shutter is opened with a finger, the locking portion is engaged with the stopper means and opened. The state is maintained, and the ball-pulling is continued. On the other hand, when the stopper means is disengaged from the engaging portion by operating the stopper means with a finger in this state, the shutter automatically closes, and the ball box is separately pulled out from under the winning ball tray, and the stopper means is removed. Is released, the engagement with the locking portion is automatically released, and the shutter is closed by the bias of the spring.

A ball hole 13 is formed in the bottom portion 12, and a shutter 14 provided on the lower surface of the bottom portion is closed to prevent the ball from flowing out.

The shutter 14 in this embodiment is housed on the upper surface of a frame plate 15 (which may be considered as a part of the bottom portion 12 or an auxiliary member) provided in parallel with the lower surface of the bottom portion 12. The frame plate 15 forms a gap between the bottom 12 and the shutter 12. The shutter slides in the gap in the left-right direction to open and close a hole 13 provided on the right side. Normally, the spring 18 is contracted between a groove-shaped accommodation chamber 16 provided on the lower surface of the shutter and a wall 17 provided on one side of the frame plate 15 in the direction of the ball hole to close the hole. It is supposed to.

The shutter has a knob 20 which also serves as a locking portion 19 at the front edge, and projects forward through a horizontally long opening formed between the bottom 12 and the front edge of the frame plate 15.

In the figure, reference numeral 21 denotes stopper means for locking the shutter 14, reference numeral 22 denotes a slider of the stopper means, and reference numeral 23 denotes an operation piece extended from the slider 22.

The slider 21 is housed so as to be able to slide up and down in a box-shaped holding portion 24 provided integrally with the rear edge of the frame plate 15, and a spring 25 always contracted between the holding portion 24 and the slider. Urged downward to abut on the bottom of the holding portion. Then, an abutting rod 26 erected from the lower surface of the slider is projected downward through a hole 27 formed in the holding portion 24.

On the other hand, the operation piece 23 extends forward through a window 28 formed on the front surface of the holding portion 24, and its tip end projects forward of the knob 20 of the shutter 14.

This operation piece is made of a synthetic resin material and has a spring property, and a right triangle-shaped engaging projection 29 is provided on the upper surface corresponding to the knob 20, and the height of the knob 20 is always set by the spring 25. Below this, the knob 20 is separated from the locking portion 19 which is one end of the knob 20. The engaging projection 29 of the operation piece 23 is provided so as to face a position immediately below the locking portion 19 of the knob 20 provided on the shutter 14 when the shutter 14 is moved to the open position, so that both correspond considerably. It is.

In the figure, reference numeral 30 denotes a shelf horizontally provided below the prize ball receiving tray 9;
Reference numeral 32 denotes a ball box placed on this shelf, and 32 denotes a guide for positioning and supporting the edge of the ball box at a fixed position so as to face an abutment rod 26 provided on the slider 21 of the stopper means. It is.

The shelf 30 is horizontally provided forward from a mounting table 33 for fixing the pachinko machine, and has a sufficient size on which the ball box 31 can be placed on the upper surface. The guide 32 is fixed to the front plate 11 to be passed to the lower front surface of the outer frame 1 of the pachinko machine main body so that the hook-shaped tip protrudes forward so that the edge of the ball box can be hooked. The upper edge of the edge faces the abutment rod 26 so that it can be pushed up from below.

In the prize ball receiving tray 9 according to the above-described configuration, the shutter 14 closes the ball punching hole 13 by the urging of the spring 18 in a normal state, so that the prize ball from the taxiway 10 can be stored. In order to remove the prize balls accumulated in this state, if you push the shutter knob 20 by hand and slide it while reducing the spring 18, you can open the ball hole 13 and drop the prize ball down Can be. At this time, if the hand is removed from the knob 20, the shutter automatically closes by the action of the spring 18, and the removal of the ball can be stopped.

As described above, the prize ball receiving tray 9 can release the ball by opening the shutter 14 by hand, but when the ball box 31 faces the prize ball receiving tray, the shutter means 14 is opened by operating the stopper means 21. The state can be maintained, and continuous prize balls can be extracted.

That is, when the ball box 31 is inserted under the prize ball tray for removal of the prize ball and placed on the shelf 30, the edge of the box that has entered under the guide 32 and penetrated hits the abutting rod 26 which hangs down. Slider 21 pressed down by spring 25 because of contact and pushing up
Operating piece which rises inside the holding part 24 and protrudes forward from the window 28
23 is raised to a position along the lower surface of the frame plate 15, and the engaging projection 29 provided on the upper surface of the tip portion is accordingly moved to the shutter 14.
(See FIG. 7). As a result, when the knob 20 is manually operated and the shutter is slid to open the hole for removing the ball as described above, the knob 20 abuts on the engaging projection 29, and this abutment is ignored. Then, when the shutter is further slid, the knob is guided by the inclined surface 29a of the projection 29, flexes the operation piece 23, climbs over the projection, and engages the upright surface 29b of the projection 29 with the locking portion 19 after passing. Will be. For this reason shutter 14
Return is blocked and the ball hole is left open (see FIG. 6).

The open state of the shutter can be released by pushing up the tip of the operation piece 23 with a finger to remove the engagement projection 29 from the locking portion 19, and the ball box 31 inserted under the prize ball tray 9 to remove the ball. Can also be released by extracting

When the ball case is removed, the thrust of the abutment rod 26 is released, the slider 21 urged by the spring 25 descends, and the operation piece 23 descends as shown in FIG. Is released from the height of the knob 20 of the shutter 14, the engagement state is automatically released, and the shutter is automatically closed by the spring 18.

FIG. 9 to FIG. 12 show a second embodiment of the present invention. This embodiment uses the spring force of the operation piece 23 in the first embodiment described above to disengage the shutter and close the shutter, whereas the operation piece engaged with the locking portion of the shutter is used. This is another embodiment in which a spring is inserted between the abutment piece receiving the edge of the ball box and the contraction of the spring releases the engagement of the locking portion so that the shutter can be closed by hand. . In the description of the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals in the drawings, and description thereof will be omitted.

FIG. 9 is an enlarged bottom view of the prize ball saucer according to the present invention,
FIG. 10 is an exploded perspective view of a main part, and FIGS. 11 and 12 are FIG. 9 XI.
It is a longitudinal cross-sectional view explaining the operation state made into the cross section along the -XI line.

The prize ball receiving tray 9 in this embodiment is provided with a frame plate 15 in parallel with the lower surface of the bottom portion 12 as in the previous embodiment, and the shutter 14 is housed in a space formed therebetween so as to be freely slidable in the left-right direction. The shutter 18 is pressed rightward by a spring 18 which is always contracted between a wall 17 provided on one side edge of the frame plate and a housing chamber 16 on the lower surface of the shutter, and the ball hole 13 formed on the bottom is closed. It is like that.

In the drawings, reference numeral 34 denotes a bearing provided on the lower surface of the frame plate 15, reference numeral 35 denotes an operation piece pivotally connected via a support shaft 36 passing to the bearing, and reference numeral 37 denotes a number of the operation piece. It is an abutting piece which is attached so as to overlap downward and one end of which is pivotally attached to the support shaft 36 so as to be freely swingable.

As shown in the drawing, the operation piece 35 is pivoted by passing a support shaft 36 through a bearing 38 provided in the middle of the length of the operation piece 35 in the longitudinal direction, and one end facing forward is provided with a knob 20 provided on the shutter 14. The other end of the shutter 14 projects backward from the rear edge of the shutter 14 so as to face a locking portion 39 extending rearward from the shutter. An engagement protrusion 40 having a right-angled triangular shape is provided on the upper surface of the rear end so as to be able to engage with the locking portion 39.

On the other hand, the abutment piece 37 has a bearing 41 at one end inserted between the bearings 38 of the operation piece 35, and is mounted on a support shaft 36 passing between the bearings so as to swing freely. A spring 42 is inserted between the end and the end, and the operating piece is positioned below the spring via the spring.

The operation piece 35 with the abutment piece 37 is provided at a predetermined position so that the engaging projection 40 can face the place where the locking portion 39 is located when the shutter 14 is opened. As shown in FIG. 11, the rear end side longer than the position of the bearing 38 serving as a fulcrum is lowered by its own weight, the engaging projection 40 projecting from the upper surface thereof is lowered below the height of the locking portion 39 of the shutter, and the abutment piece 37 The extension of the spring 42 causes its free end to hang below the rear end of the operation piece.

Therefore, when the shutter 14 is slid to the left against the spring 18 in the above state, the ball hole 13 is opened,
The prize balls stored in the prize ball tray 9 can be extracted, but when the hand is released from the knob 20, the shutter 14 is automatically closed by the bias of the spring 18.

On the other hand, when the ball box 31 is next inserted under the prize ball tray 9 and the abutting piece 37 hanging down at the edge thereof is pushed up, the rear end of the operating piece connected via the spring 42 is pushed up. The engaging projection 40 provided on the shutter 14 rises to the height of the locking portion 39 of the shutter 14 (see FIG. 12). Therefore, when the knob 14 is operated to open the shutter 14,
As the locking portion 39 slides, it comes into contact with the engagement protrusion 40. Then, when the sliding portion is further slid, the locking portion 39 rides over the spring 42 while compressing the spring 42 by guiding the slope 40a of the engaging protrusion, and at the time when the spring 42 is over, the spring 42 is restored to the vertical surface 40b of the engaging protrusion 40. Will engage. Therefore, after the ball box is inserted under the winning ball tray and faces the ball hole 13, the shutter remains open due to the engagement even if the hand is released from the knob 20 of the shutter.

The opening of the shutter 14 can be automatically released by removing the ball box 31 and lowering the engagement projection 40 of the operation piece. On the other hand, even when the ball box 31 is inserted, the tip of the operation piece 35 protruding forward of the prize ball tray is pushed up, the pivot 36 is swung to the fulcrum, and the engagement projection 40 is lowered. The open state can be released. Of course,
In this latter case, it is needless to say that when the knob is operated and the shutter is opened, the locking portion 39 is engaged with the engagement projection 40 again, so that the ball hole can be left open.

[Effects of the Invention] As described above, the present invention has been described based on the embodiments. As is clear from both embodiments, the prize ball saucer of the present invention always closes when the ball box is not inserted under the prize ball saucer. It acts to be closed by being urged in the direction, so when it is opened, it is necessary to hold an open state by putting a hand on a knob or the like, but it can be freely opened and closed, while receiving a prize ball When the ball box is inserted under the prize bowl, the engagement between the locking portion of the shutter and the stopper means becomes possible,
Since the open state is maintained by the engagement of the two, the shutter can be kept open even if the hand is released from the shutter, and the ball can be continuously removed.

The prize ball saucer of the present invention can automatically close the open state of the shutter by removing the ball box from under the prize ball saucer, and at the same time, manually engages the stopper means while the ball box is inserted. It is very advantageous when a player removes a ball because the shutter can be closed by removing the shutter.

In particular, the prize ball saucer of the present invention does not scatter the ball on the floor and always keeps the ball open when the ball box is removed, since the stopper function of the stopper means is lost and the shutter automatically closes when the ball box is removed. Since the box receives the ball falling through the box, it is possible to effectively avoid problems such as the forgetting of tightening which occur in the conventional prize ball tray with stopper.
