This coin sorting apparatus is provided with a coin insertion part on one side and a coin discharge part for sending out coins into the apparatus main body on the other side, and a regular discharge part is provided between the coin insertion part and the coin discharge part. A sorting / returning unit for disparate coins different in size from the coin and a returning unit for surplus coins are provided.

Next, an outline of a basic structure of a coin sorting apparatus to which the present invention is applied will be described with reference to FIGS. FIG. 10 and FIG. 11 are front views showing the entirety of two general types of coin sorting devices A and A ′ used exclusively for a throttle machine (commonly known as a pachislot) installed in a pachinko parlor. 12 (a) is a cross-sectional view of the coin return section of FIG. 10 taken along line W′-W ′, and FIG. 12 (b) is a cross-sectional view of the coin return section of FIG. 11 taken along line Y′-Y ′.

In FIG. 10 and FIG. 11, a coin C inserted through a coin slot 9 provided in a device body (hereinafter sometimes abbreviated as device body) of a throttle machine (not shown) passes through a coin insertion portion 1a. Through the coin sorting device A,
It is guided into A 'and sent out from the coin discharge section 1b into the apparatus body.

[0005] The coin sorting devices A and A 'are based on a plate-shaped coin sorting device body (hereinafter referred to as the device body) 1 attached to the inside of the front surface (door) of the device body, and have one side (FIGS. 10 and 10). 11 on the left side of the drawing) coin insertion section 1a
However, a coin discharge portion 1b is disposed on the other side (the right side of the paper surface of FIGS. 10 and 11). The coin insertion portion 1a and the coin ejection portion 1b are connected by a coin guide passage 3 which is formed by linearly protruding the surface of one side edge (lower side of the paper in FIGS. 10 and 11) of the apparatus main body 1, and The coin C inserted from the coin insertion part 1a is guided to the circumference by the coin guide passage 3 and rolls to the coin discharge part 1b. The other side edge of the apparatus main body 1 (upper side in FIGS. 10 and 11) is inclined closer to the front side of the apparatus main body than one side edge of the apparatus main body (lower side in FIGS. 10 and 11). The coin C is guided by the inner surface of the apparatus main body 1 to the side of the coin C and moves to the coin discharge section 1b.

In the apparatus main body 1, different coins different in size from regular coins are removed from the coin sorting apparatus and returned to a coin return slot (not shown) of the apparatus main body in order from the coin insertion portion 1a side. A sorting unit 2; a coin return unit 5 for returning excess coins exceeding a predetermined number (for example, three) necessary for operating a device such as a throttle machine to a return port of the device body; Coin C
And a detection unit 4 for detecting the passage of the vehicle. A cover 10 is rotatably attached to the apparatus main body 1 by a shaft 10b in the different kind coin sorting section 2, and is normally urged in a closing direction by a spring 10a.

[0007] The coin return section 5 has an opening 5 through which a part of the coin guide path 3 is cut out to drop excess coins.
a is formed and normally closed by an openable / closable lid 7. In the example (coin sorting device A) shown in FIGS. 10 and 12 (a), a solenoid 6 is provided to face the opening / closing lid 7, and when the solenoid 6 is excited, the opening / closing lid 7 is attracted to the solenoid 6. Thus, the opening 5a is opened. On the other hand, in the example (coin sorting device A ′) shown in FIGS. 11 and 12 (b), a solenoid 6 is provided so as to face the opening / closing lid 7, and when the solenoid 6 is excited, the opening / closing lid 7 is attracted to the solenoid 6. Thus, the opening 5a is closed.

[0008] The coin return section 5 of the apparatus main body 1 includes:
An openable / closable cover 11 is provided for the apparatus main body 1. A helical spring 11a is wound around a shaft 11b for holding the cover 11 openably and closably on the apparatus main body 1, and constantly urges the cover 11 in the closing direction. When cleaning and repairing the coin sorting devices A and A ', the cover 11 can be opened to perform work. When the cover 11 is closed, a gap is formed between the cover 11 and the apparatus main body 1 so that the coins C can pass in a single line, and the coin C flows to the next coin discharge section 1b through this gap. FIG. 10
In the example shown in FIG. 12A (coin sorting device A), the opening / closing lid 7, the solenoid 6, and the like are attached to the front side of the cover 11 via the bracket 12. on the other hand,
Examples shown in FIGS. 11 and 12B (coin sorting device A ′)
In this case, the opening / closing lid 7 is provided via a bracket 12, and the solenoid 6 is directly attached to the front side of the cover 11.

The coin sensing means 4 includes two sets of sensors 4 disposed above the coin return section 5 and near the coin discharge section 1b.
d, 4e, and these sensors 4d, 4e are mounted on the back side of the apparatus main body 1 via mounting members 4a. Holes 4b and 4c of substantially the same size are opened at the same position above the opening 5a of the apparatus body 1 and the cover 11, and the sensors 4d and 4e are opened from the holes 4b and 4c.
Projecting to the top of a. Each of the sensors 4d and 4e has a light emitting tube and a light receiving tube which are provided opposite to each other with the coin guide passage 3 interposed therebetween, and the coin C emits a light beam traversing between the light emitting tube and the light receiving tube. It is a photoelectric sensor that outputs a coin sensing signal by blocking. Therefore, the surface of the light emitting tube and the light receiving tube facing the coin guide passage 3 does not protrude from the inner surfaces of the apparatus main body 1 and the cover 11 so that the coin C can pass smoothly between the light emitting tube and the light receiving tube. Are arranged so as to be included in substantially the same plane as the inner surface.

When the coin C sequentially crosses the sensors 4d and 4e, a detection signal is output from the sensors 4d and 4e to a control device such as a sequencer provided in the apparatus main body. The control device counts the number of coins C passing from the number of times the detection signal is input, and outputs a command signal when it is determined that a predetermined number of coins have been sent to the device main body, and outputs a command signal as shown in FIGS. In the example (a) (coin sorting device A), the solenoid 6 fixed to the back side of the bracket 12 is excited, and the opening / closing lid 7 which is normally closed by the urging means 12a (coil spring) is opened to open the opening 5a. Is opened. 11 and 12
In the example shown in (b) (coin sorting device A '), the cover-1
The excitation of the solenoid 6 fixed to the front side of the solenoid 1 is released, and the open / close lid 7 which is normally closed by the excitation of the solenoid 6 is opened.
Is opened by the urging means 12a (coil spring) to open the opening 5a. As a result, surplus coins fall from the opening 5a and are returned to the coin return slot of the device body.

As shown in the cross-sectional views of the coin return portion 5 in FIGS. 12A and 12B, in the structure of the conventional coin return portion, when the open / close lid 7 shown by a solid line is closed, The upper surface of the bent front end portion 7a of the opening / closing lid 7 contacts the lower edge 1c of the apparatus main body 1, and the opening 5a is located at the front end portion 7a of the opening / closing lid 7.
And the lower end of the apparatus main body 1 are completely closed. On the other hand, FIG. 10, FIG. 11 and FIG.
As shown in (b), the cover 11 in the opening 5a

A slight gap is provided so as not to hinder contact with the lower edge 1c.

The coin sorting apparatus A configured as described above
Alternatively, when playing a game with the throttle machine device body to which A 'is attached, the opening / closing lid 7 of the coin return unit 5 operates as follows. (1) At the start of the game Before the coin C is inserted into the throttle machine, the opening / closing lid 7 is closed, and up to a predetermined number (for example, three) of regular coins C are inserted. The opening / closing lid 7 remains closed until the coin is discharged from the coin discharge section 1b to the apparatus main body. (2) When a predetermined number of coins C have been sent to the device body,
Throttle machine equipment itself is ready for play.
When a play start trigger (knob or the like) on the front of the throttle machine device body is operated, reels of a predetermined number (for example, three) of reel units start to rotate, and simultaneously, the opening / closing lid 7 is opened, and coins are played during play. Even if C is inserted, the coin C is returned from the coin return unit 5 to a "cancel" state. (3) When all of the predetermined number of reel rotation stop triggers (push buttons, etc.) on the front of the throttle machine device main body are operated or all reels stop rotating, play ends and the next play starts. For preparation, the open / close lid 7 of the coin return unit 5 is closed.

[0013]

However, the structure of the coin return section of the conventional coin sorting apparatus as described above has the following problems. That is, as described above, at the end of the play of the throttle machine device body, the opening / closing lid 7 of the coin return unit 5 closes in preparation for the start of the next play. FIG. 13 shows the relationship between the timing of coin C being inserted for the next play and passing through the coin return unit 5.
The following phenomena as shown in (a) and (b) occur.
13 (a) and 13 (b) correspond to FIGS. 10 and 1 respectively.
2 (a) (coin sorting device A) and FIGS. 11 and 1
In the example shown in FIG. 2B (coin sorting device A ′), three open / close positions including the fully closed position and the fully open position of the open / close lid 7 and the operation of the device main body 1, the cover 11 and the coin in the coin return unit 5 are described. It is a schematic sectional drawing which shows the example of a relationship.

(1) Before or immediately after the closing operation of the opening / closing lid 7 is started, the coin return unit 5 is
When the coin C is inserted at the timing when the coin C reaches the coin return unit 5 when the opening 5a of the coin C is hardly closed and the opening 5a is still substantially open, the coin C is returned. It is returned from the unit 5 (the state shown by the two-dot chain line in FIG. 11, the coin C ₃ , the open / close lid 7 ₃ , and the open / close lid tip 7 a ₃ ).

(2) After the closing operation of the opening / closing lid 7 is completed or closed.
Immediately before the end of the operation, the coin return unit 5 is
After the opening 5a is substantially closed, the coin C
The coin C is inserted at the timing of passing through the in-return unit 5.
When the coin is released, the coin is discharged from the coin ejection section 1b to the slot machine.
Sent to the thin device body (the solid line in FIG.
₁, Opening and closing lid 7₁, Open / close lid tip 7a₁State).

(3) Just before the closing operation of the opening / closing lid 7 is completed, the coin C can fall from the opening 5a between the front end 7a of the opening / closing lid 7 and the lower edge 1c of the apparatus main body (base plate) 1. The tip part 7a of the opening / closing lid 7 is falling when the limit gap is open or when the lower end of the coin C starts dropping to a position slightly lower than the lower end of the apparatus main body (base plate) 1. When the coin C is inserted so that the coin C reaches the coin return portion 5 at a timing such that the coin C comes into contact with the side surface of the coin C, the coin C is moved to the front end portion 7a of the opening / closing lid 7 and the device main body 1. May be caught between the lower edge 1c of the cover 11 and the inner surface of the cover 11 (FIG. 13).
(A state shown by a dashed line, a coin C ₂ , an opening / closing lid 7 ₂ , and an opening / closing lid tip 7 a ₂ ).

Although the phenomena such as the above (1) and (2) are not special problems, when the phenomena such as the above (3) occurs,
Since the coin C is jammed in the coin return section 5, the next play becomes impossible. Therefore, when such a clogging of the coin C occurs, the throttle machine detects this and issues an alarm, so that an employee such as a pachinko parlor can solve such a trouble and play the throttle machine. It must be restored to a state. Also, if such troubles occur frequently, simultaneously, continuously or intermittently with multiple throttle machines, the troubles will not be resolved in time, and the customer will lose trust in the store, or You have to deal with trouble by increasing the number of uneconomical.

The present invention solves the problems of the conventional coin sorting apparatus as described above, particularly due to the structure of the coin return section, and at what timing after the end of the previous play on a throttle machine or the like. It is an object of the present invention to provide a highly reliable coin sorting apparatus that hardly causes a coin clogging in a coin return section even when a play coin is inserted.
