A finger is inserted into the concave portion provided on the upper storage box 153a side, and the locking claw 177 of the storage box cover 156 is pulled up.

Next, a mounting method for mounting the polishing apparatus 54 to the mounting substrate 70 will be described with reference to FIGS. 9A and 9B. The mounting substrate 70 is provided with a locking member 179 and a locking member 180 for mounting the polishing device 54. Further, at the end of the locking member 179, a locking portion 179a for locking the bottom of the polishing device 54 is formed, and at the end of the locking member 180, the upper portion of the polishing device 54 is locked. Are formed.

When the polishing apparatus 54 is mounted on the mounting substrate 70, the locking portions 180 a formed on the locking member 180

Is fixed to the mounting board 70 by the locking portions 180a and the locking portions 179a. The polishing apparatus 54 is mounted on the mounting substrate 70.
It is necessary to rotate the connecting arm 151 (see FIG. 6) against the urging force of the elastic member 160 (see FIG. 6) so that the connecting arm 151 does not come into contact with the roller 157.

As described above, the polishing device 54 is mounted on the mounting substrate 70.
The attachment and detachment operation of the polishing device 54 is facilitated because the attachment device is configured to be detachable. Moreover, since the polishing device 54 can be attached to the mounting substrate 70 with the polishing cloth 63 laid therein in advance, the polishing device 54 on which the polishing cloth 63 is laid is prepared in advance. 54 can be quickly replaced.

FIG. 11A is a sectional view taken along line AA of FIG. In the upper storage box 153a, the ball guiding member 1 constituting the upper wall of the ball guiding path 154 (see FIG. 6) is provided.
68 is fixed by a screw 169 via a fixing member 172b. On the other hand, a ball guide member 170 constituting the lower wall of the ball guide path 154 (see FIG. 3) is fixed to the lower storage box 153b by a screw 169 via a fixing member 172a. The upper storage box 153a and the lower storage box 153b are provided with a locking claw 173 and a locking portion 17.
4 (see FIGS. 8 and 11 (b)), and is locked at the illustrated position, and the storage box cover 156 covers the front surface at that position.

The ball guide members 168 and 170 are made of a synthetic resin material.
Are formed. On the other hand, a concave groove 170a is formed on the upper surface of the ball guiding member 170, and an elastic member 175 as an urging means for pressing the polishing pad 63 against the pachinko ball is fitted in the concave groove 170a. . The elastic member 175 is made of a soft rubber material or the like, and has a concave groove 175a having a semicircular cross section whose inner diameter is substantially the same as the outer diameter of the pachinko ball is formed on the upper surface. This elastic member 17
Numeral 5 is detachably attached to the concave groove 170a, and when it has deteriorated due to long-term use, it can be easily replaced by opening the upper storage box 153a.

In this embodiment, a concave groove 175a is formed on the upper surface of the elastic member 175.
If the elastic member 75 is appropriately formed of an elastic member having an elastic restoring force, the elastic member 17 can be formed without forming the concave groove 175a.
5 itself is elastically deformed along the lower half of the pachinko ball and the polishing cloth 63 is adhered to the pachinko ball, so that the pachinko ball can be polished effectively.

The polishing cloth 63 used in this embodiment is a ribbon-shaped woven cloth of ultra-fine fiber yarn having a thickness of 0.5 mm, a width of 15 mm, and a length of about 7 m. Reel 65
The contact surface with the pachinko ball is 120 mm,
It is possible to use the polishing pad once a day under the control of the polishing cloth to be described later, so that the polishing pad can be used continuously for about 60 days.
In this case, the setting is such that about 50,000 pachinko balls can be effectively polished within one day.

The yarn diameter of the ultrafine fiber yarn used for the woven fabric forming the ribbon-shaped polishing cloth 63 is about 20 μm, which is the yarn diameter used in conventional woven fabrics and nonwoven fabrics. In this case, as shown in FIG. 13 (a), since the thickness of the fat or the like adhering to the pachinko ball is about 10 μm, the thin oil or fat film having a thickness of about 10 μm has a yarn diameter of about 20 μm. In the case of woven or nonwoven fabrics, it is not good to take the wiping and the wiping oils and fats into the interior of the fiber, and a thin film of the oils and fats remains as wiping residue. By making the microfiber yarn of 10 μm or less, for example, a yarn diameter of about 2 μm as in this embodiment, the wiped oil film and dirt move to the gap inside the microfiber yarn constituting the woven fabric by capillary action. And there The trapped state. Therefore, the pachinko ball can be wiped off without leaving any dirt on the surface thereof, and no oil film or the like remains on the sliding surface of the polishing pad 63, so that the oil film or dirt can be wiped off repeatedly.

The weaving method of using these ultrafine fiber yarns as a woven fabric may be plain weaving, twill weaving, satin weaving, tricot, circular knitting, or the like. In order to eliminate the ground thickness and increase the bulk, and to appropriately achieve appropriate water absorption (oil absorption) and workability, a double woven, twill, satin or circular knit is preferred.

Further, the synthetic resin used as these ultra-fine fiber yarns can be processed into the above-mentioned ultra-fine fiber yarns of about 10 μm or less, and can sufficiently withstand friction with pachinko balls. It is preferably one having strength, and synthetic fibers such as nylon (polyamide), polyester, acrylic, saran, polyvinyl alcohol, and polyolefin can be used. In particular, in this embodiment, FIG.
As shown in FIG. 3 (b), a polyester resin having a hard segment having high crystallinity and a soft segment having low crystallinity and high flexibility in a molecular chain, and the hard segment and the soft segment form a sea-island structure. You are using As described above, the polyester resin having the sea-island structure can easily make the spun fiber ultrafine by performing a process of eluting a part of the soft segment as the sea portion into a predetermined solvent after spinning. Not only that, since the polyester resin itself has relatively high chemical resistance, it is also possible to impregnate the obtained woven fabric with chemicals and the like, for example, by impregnating a deodorant or an antibacterial treatment agent in advance. Is also good.

As shown in FIG. 12 (a), the polishing cloth 63 in the form of a ribbon according to the present embodiment, as shown in FIG.
7 is an angle α (30 degrees in this embodiment), and the weft 68 is an angle β
(In this embodiment, 120 degrees), and the warp yarn 67 has a higher weave yarn density than the weft 68 weave yarn density. Has a relatively large expansion / contraction ratio in the width direction and a relatively small expansion / contraction ratio in the longitudinal direction.

As described above, by making the expansion and contraction rate in the longitudinal direction of the polishing cloth 63 lower than the expansion and contraction rate in the width direction, the contraction rate in the longitudinal direction which is a moving direction to which a large tension is applied becomes low, 63 can be brought into contact with a pachinko ball, which is a game medium, with a high pressure, and a higher clean state can be obtained. However, the present invention is not limited to this.

Further, in this embodiment, as described above, the warp 67 and the weft 68 of the woven fabric are cut so as to have predetermined angles, and the warp 67 and the weft 68 have different yarn densities. Due to the difference in frictional force between the warp 67 and the weft 68, as well as the difference in frictional force between the warp 67 and the weft 68, as shown in FIG. It rotates in the direction of the middle arrow, and the pachinko balls are polished evenly over the whole.

As described above, in this embodiment, as a method of appropriately rotating the pachinko balls in the horizontal direction with respect to the traveling direction so that the pachinko balls are uniformly polished, the cutting direction of the woven cloth is changed to the warp 67 as described above. And the weft 68 is cut so as to have a predetermined angle. However, the present invention is not limited to this. As a method of appropriately rotating these pachinko balls in the horizontal direction with respect to the traveling direction. In the longitudinal direction of the polishing cloth 63, the fiber density in the left and right regions is formed to be different from each other, and the friction coefficient of both regions is made different, so that the pachinko ball is given a horizontal rotation with respect to the traveling direction. You may do it.

Further, as described above, the warp 67 has the angle α =
The angle of the weft thread 68 is not limited to 30 degrees, and the angle of the weft thread 68 is not limited to 120 degrees. These angles are determined so that the pachinko balls are evenly polished depending on the surface condition of the polishing cloth 63 to be used and the length of the polishing process. Then, it may be appropriately selected.

The method of forming a region having a large frictional resistance and a region having a small frictional resistance may be realized by, for example, changing the fiber density of a woven fabric. May be used,
Further, a coating agent or the like having an appropriate friction coefficient may be applied to the sliding contact surface of the polishing cloth 63 to form a region having a large friction resistance and a region having a small friction resistance.

The ultrafine fiber yarn made of the polyester resin used for the polishing cloth 63 of the present embodiment is a long fiber without fluffing, so that it does not self-dust and is substantially dust-free. Has characteristics.

Further, both ends of the polishing cloth 63 of this embodiment are
Heat cutting is performed in which a predetermined width of the cut end is cut by a heat roller heated to a predetermined temperature to form a heating portion 66 at the time of cutting. The terminals can be fused to each other to suppress dust generation. As described above, the use of the heat-cut woven cloth capable of suppressing dust generation from the cut end portion suppresses the generation of lint and dust from the cut end portion during polishing, and these dusts are used to remove pachinko balls. Frequently enter the transfer path of the
However, the present invention is not limited to this, because it does not become entangled with the drive shaft of the lift motor 122 and can reduce failures.

The polishing cloth 63 can be subjected to various treatments. In this embodiment, a relatively high electric conductivity is provided at predetermined intervals inside the warp 67 having the high density. The antistatic yarn (fiber) 67 ′ having the following is woven, so that the static electricity generated by the sliding contact with the pachinko balls and other members can be efficiently released to the outside.

As these antistatic yarns (fibers) 67 ′,
A filament prepared by mixing and spinning a block polyetheramide or a grafted polyetheramide (modified polyamide) containing a polyalkylene ether segment with a polyamide or polyester, and mixing the modified polyamide with the polyamide or polyester as dispersed particles elongated in the fiber axis direction. (Yarn), a filament (yarn) composed of a polymer containing a conductive substance such as carbon black or carbon fiber, particularly a filament composed of a polymer containing a conductive substance in the core component of a core-sheath composite fiber, Metal filaments and the like.

In the present embodiment, the warp 6
7, a part of the antistatic yarn (fiber) 67 ′ is used. However, the present invention is not limited to this. The antistatic yarn (fiber) may be included in the weft 68, All of the weft yarns may be antistatic yarns (fibers).

Further, in the present embodiment, the various ball passages (recovery gutter 34, driving ball collecting gutter 40, transport path 62) and the like formed on the back surface of the pachinko machine 2 are all in a state where the pachinko balls are aligned in the transfer direction. As shown in FIG. 2, for example, the inner peripheral surface of the driving ball collecting gutter 40 and a part of the lower surface of the ball tank 59 are connected via a ground wire 186 as shown in FIG. It is composed of a conductive member (shown by oblique lines in the figure) connected to an appropriate place (for example, a ground provided on a pachinko island). By doing so, the static electricity generated in the pachinko balls is effectively removed during the transfer. In addition, not only the peripheral surface of some of the ball passages as described above, but also the entire peripheral surface of the ball passage can be made of a conductive member, and the charge can be more effectively removed.

As shown in FIG. 11A, guide portions 182 are formed on the left and right sides in the longitudinal direction of the elastic member 175 of the ball guiding member 170 so as to rise above the uppermost position of the elastic member 175. The polishing cloth 63 is guided so as to move along the longitudinal direction. Therefore, the polishing cloth 63 always comes into contact with the pachinko balls in an appropriate state without fail, so that a reduction in polishing ability can be prevented.

The pachinko balls also move in a single line in the ball guide path 154 in the polishing device 54. Since the structure of the polishing device 54 is compact, maintenance work and control of the drive unit are easy. Not only
Pachinko balls can be polished reliably.

As described above, in this embodiment, the polishing cloth 63 is not always conveyed and wound up in accordance with the lifting of the pachinko balls, but rather until a certain amount of dirt adheres to the polishing cloth 63 in contact with the pachinko balls. The pachinko ball is polished using the same portion. Then, the take-up motor 79 is driven when a certain amount of dirt has adhered to the polishing cloth 63, and the take-up motor 79 is driven when the dirt-removed polishing cloth 63 is wound up and a new clean part is unwound. Stops. Therefore, the polishing cloth 63 can be used more effectively as compared with a method in which the polishing cloth is always transported in accordance with the lifting of the pachinko balls.

Next, the operation when the polishing apparatus 54 is mounted will be described in detail. Ball tank 59 from pachinko machine 2
The pachinko ball discharged to is returned to the ball reduction machine 55,
Sprocket 58 driven by lift motor 122
(Refer to FIG. 2). The pachinko balls being transported are polished by contacting the polishing cloth 63 in the polishing device 54.

If the pachinko balls are repeatedly polished on the polishing cloth 63, a certain portion of the polishing cloth in the ball guide path 154 is deteriorated, and the polishing ability is reduced. In this embodiment, for example, when the operation time of the pachinko machine 2 reaches a predetermined time (a predetermined number of driving balls is detected by the driving ball detector 48), the polishing ability of the certain portion is reduced. It is configured so as to be determined.

When the operation time of the pachinko machine 2 reaches a predetermined time, the take-up motor 79 for driving the rotating shaft 75 is driven, and a new polishing pad 63 is unwound. Is updated. At this time, in order to wind up only the used portion and not to wind up the unused portion unnecessarily, the length between the left and right ball guide rollers 155a and 155b is always used when the polishing cloth is updated. You only need to control to wind up. This control method will be described later.

As shown in FIG. 11 (a), the polishing cloth 63 between the left and right ball guide rollers 155a and 155b is constantly urged upward by the lower elastic member 175 and pressed against the pachinko balls. It has become. Elastic member 17
Groove 175 formed along the longitudinal direction on the upper surface of
Since a is configured in a semicircular shape along the spherical surface of the pachinko ball, the polishing pad 63 is deformed along the shape of the lower half of the pachinko ball. Thereby, the area where the polishing cloth 63 contacts the surface of the pachinko ball increases. Therefore, the concave groove 175
As compared with the case where a is not provided, not only can a wide range of pachinko balls be efficiently polished, but also the tape width of the polishing cloth 63 can be in contact with the surface of the pachinko balls exposed from the transport path 62. Since it is configured to have a necessary and sufficient width, the polishing pad 63 can be used without waste. Further, the elastic force of the elastic member 175 enhances the adhesion of the polishing pad 63 to the pachinko balls, thereby improving the polishing effect.

Next, a method of controlling the driving of the polishing device 54 and the ball reducing machine 55 in the pachinko machine 2 shown in FIG. 2 will be described below.

First, the lift motor 1 in the ball reduction machine 55
As shown in FIG. 4, the reference numeral 22 is connected to the point control microcomputer 120 via an overload detection circuit 125 and a lift control circuit 121. The point control microcomputer 120 controls the lift control circuit 121 The drive control of the lift motor 122 is performed via the motor, and the sprocket 58 is rotated as necessary to lift the pachinko balls. As shown in FIG. 14, the overload detection circuit 125 measures a current value flowing through a resistor provided inside by detecting a potential difference between both ends of the resistor.

Point control microcomputer 120
FIG. 15 shows a state in which the lift motor 122 is driven.
As shown in (a), the fluctuation of the voltage accompanying the driving of the lift motor 122 is sampled from the overload detection circuit 125 at predetermined intervals. Then, for example, the lift motor 12
2, that is, the potential difference between both ends of the resistor increases and the voltage exceeds a predetermined threshold as shown in FIG. It is determined that the lift motor 12 has been applied to the lift motor 12 via the lift control circuit 121 (see FIG. 4).
2 and outputs an overload detection signal to the host computer 49 through the microprocessing unit 50, displays an error message on the display device 107, and furthermore, displays the dot analog display 105 via the LED circuit. Flashes. The overload detection signal is provided with identification data of the pachinko machine 2 so that the host computer 49 can identify which pachinko machine 2 has an abnormality.

Since the above-described voltage fluctuation may temporarily occur due to some factors,
The output of these overload detection signals to the outside is performed when the microcomputer 120 for point control performs sampling a predetermined number of times (for example, 10 times) and, as a result, detects a voltage exceeding the threshold value for all 10 times. This can prevent malfunction when the drive operation of the lift motor 122 is normal.

The winding motor 79 in the polishing device 54
As shown in FIG. 4, the microcomputer 120 is connected to a point control microcomputer 120 via an overload detection circuit 124 and a polishing control circuit 123, and the point control microcomputer 120 is wound via the polishing control circuit 123. The drive of the take-up motor 79 is controlled, and in this embodiment, a predetermined amount of tape member is wound up after a predetermined time stored in advance.

Point control microcomputer 120
While the winding motor 79 is being driven,
Of the voltage accompanying the driving of the circuit is sampled from the overload detection circuit 124 at predetermined time intervals. Then, for example, when the current flowing through the winding motor 79 increases, that is, the potential difference between both ends of the resistor increases and the voltage exceeds a predetermined threshold, the winding motor 79 is overloaded by some factor. Thus, the drive control of the take-up motor 79 is performed via the polishing control circuit 123 (see FIG. 4), and an overload detection signal is output to the host computer 49 via the micro-processing unit 50. , An error message is displayed, and the point analog display 105 blinks via the LED circuit. The overload detection signal is provided with identification data of the pachinko machine 2 so that the host computer 49 can identify which pachinko machine 2 has an abnormality.

As described above, in the ball reducing machine 55, the pachinko balls bite between the teeth of the sprocket 58 and the transfer pipe, and resistance is added to the rotation of the sprocket 58 due to factors such as entry of dust. Lift motor 12
When a load equal to or more than a predetermined value is applied to 2, the driving of the lift motor 122 is automatically stopped by the point control microcomputer 120. Further, in the polishing device 54, during the winding operation of the polishing cloth 63, when a resistance of the rotation of the winding motor 79 is generated due to some factor such as entry of dust and a load of a predetermined value or more is applied to the winding motor 79, the holding point is increased. The drive of the winding motor 79 is automatically stopped by the control microcomputer 120.

Therefore, when there is an abnormality in the rotation operation of the lift motor 122 and the rotation operation of the winding motor 79 in the polishing device 54, this abnormal signal is sent to the host computer 4.
9 and the point analog display 105 of the pachinko machine 2 so that the clerk or the administrator can quickly recognize and perform maintenance accordingly.

Further, even if no immediate action is taken, the load is not applied to the lift motor 122 and the winding motor 79 for a long time, and the motors do not abnormally generate heat. Damage to members such as the teeth of the sprocket 58 due to the torque of the motor is prevented.

The output of these overload detection signals is made not only by the blinking display of the dot analog display 105 and the error message display on the screen of the display device 107 of the host computer 49 as described above, but also by For example, an appropriate indicator lamp (not shown) separately provided on the pachinko machine 2
, Or through the external output terminal, the pachinko machine 2
May be performed by turning on a call lamp (not shown) provided above, or by outputting sound from a speaker. As described above, the operation abnormality is notified to the display device, the speaker, and the like, so that the clerk can easily recognize the abnormality of the polishing apparatus without opening the pachinko machine 2.

Further, after such notification is given, the driving of the ball hitting motor 29 of the pachinko machine 2 during the game is stopped by the point control microcomputer 120,
It is also possible to make it impossible to play. In this case, for example, if the pachinko machine 2 is in a big hit, the control of temporarily stopping the big hit state and returning to the original gaming state after the error is released is simultaneously performed. In this way, the game is not continued for a long time in a state where the lift motor 122, the winding motor 79, and the like are not operating normally, so that damage can be minimized.

If maintenance is not performed after such notification, for example, the pachinko machine 2
When the power is turned on, the fact that maintenance has not been performed may be displayed as an error message on the screen of the variable display device 18 of the pachinko machine 2, for example. Alternatively, if maintenance is not performed even after a predetermined period has passed since the notification due to negligence on the gaming side,
It is also possible to deactivate the pachinko machine 2 as sanctions and to make the pachinko machine disadvantageous.

Here, a method of controlling the renewal of the polishing cloth (polishing tape) in the present embodiment will be described below with reference to FIG. 6 and FIGS.

As shown in FIG. 6, the rotating shaft 75 of the polishing apparatus 54 of this embodiment is connected to a winding motor 79 and
The sprockets 58 are driven to rotate by lift motors 122, respectively. Also, the mounting board 70
When the connection arm 151 is rotated counterclockwise in a state where the polishing device storage box 153 is mounted on the polishing device, and the pressing roller portion 163 is pressed against the polishing cloth 63 along the roller 157, the polishing cloth 63 is sent out. Rotary table 150
Is to be driven. This rotary table 150
Of the through hole 1 provided in the turntable 150 with the rotation of
50a is detected by the feed amount sensor 152.

That is, the number of times the through hole 150a is detected by the feed amount sensor 152 when the polishing pad 63 of a fixed length is unwound is determined in advance by the point control microcomputer 120.
Remember. Then, during execution of the polishing cloth (polishing tape) update control, the winding motor 79 is driven while the through holes 150a are detected the number of times based on the memory. With this configuration, regardless of the diameter of the polishing pad 63 wound by the winding reel 65, the winding motor 79 may be stopped based on the detection of the same number of through holes 150a. In addition, the control contents can be simplified.

As described above, the embodiment shown in FIG. 6 can be used not only for the polishing cloth (polishing tape) renewal control but also for the winding end advance notification control and the winding end control described later.

Next, a control procedure of the point control microcomputer 120 (see FIG. 5) provided on the pachinko machine 2 will be described. FIGS. 16 to 18 are flowcharts showing control procedures of polishing tape (polishing cloth) updating control, winding end notice notification control, and winding end control, respectively.
The point control microcomputer 120 executes each control in accordance with a control program based on these flowcharts. A control program based on these flowcharts is executed by the microcomputer 12 for controlling the score.
0 is stored in the ROM.

First, the control procedure of the polishing cloth (polishing tape) update control will be described with reference to the flowchart of FIG.
In S1, it is determined whether the winding of the polishing pad 63 is being updated. If not, the process proceeds to S2, where it is determined whether the update time has come. Specifically, as described above, it is determined whether or not the cumulative operation time of the pachinko machine 2 has reached a predetermined time. If it is not the update time, the process ends. On the other hand, if it is the update time, the process proceeds to S3, and it is confirmed how many times the winding update has been performed. That is, the number of updates is confirmed. Next, in S4, the take-up motor 79 is driven by a rotation angle corresponding to the number of updates, the renewal of the take-up of the polishing pad 63 between the ball guide rollers 155a and 155b is started, and the process ends.

On the other hand, if it is determined in S1 that the winding update is being performed, the process proceeds to S5. In S5, it is determined whether the winding motor 79 has reached a predetermined rotation amount. That is, it is determined whether the winding motor 79 has been operated by a predetermined rotation angle according to the number of updates. Then, if the predetermined rotation amount has not been reached, the process ends. On the other hand, when the rotation amount reaches the predetermined rotation amount, the process proceeds to S6, and the winding motor 79 is controlled to stop. Next, the process proceeds to S7, where 1 is added to the number of winding updates, and the post-processing ends.

Next, the control procedure of the winding end notice notification control will be described with reference to the flowchart of FIG. First, S
At 21, it is determined whether or not the notice is being notified.
If the notification is not in progress, the process proceeds to S22, and it is determined whether the winding motor 79 has been driven. If the take-up motor is not driven, the process ends. on the other hand,
If the winding motor 79 has been driven, the process proceeds to S23, where the driving time of the winding motor 79 is cumulatively added. Next, S24
It is determined whether or not the end notice time has been reached. Specifically, it is determined whether or not the driving time of the motor that has been cumulatively added in S23 has reached a predetermined value. If the end notice time has not been reached, the process ends. On the other hand, if the end notice time has been reached, S25
And the process ends after the notification operation is started. Here, the notification operation includes, as described above, the blinking display of the dot analog display 105, the output of a predetermined notification sound from a speaker (not shown), or the like, and the winding end notice signal to the host computer 49 as appropriate. Output.

On the other hand, when it is determined in S21 that the notice is being notified, the process proceeds to S26, and it is determined whether or not all the winding operations have been completed. That is, it is determined whether all the polishing cloths 63 have been unwound from the unwinding reel 64. Specifically, the feed amount sensor 15 shown in FIG.
According to 2, it is determined whether or not the through hole 150a has been detected a preset number of times (cumulative number). If the through hole 150a has not been detected by the feed amount sensor 152 a preset number of times, it is determined that the winding has not been completed, and the process ends as it is. On the other hand, when it is determined that the winding has been completed, the process proceeds to S27, and the notification operation performed in S25 ends. Next, the process proceeds to S28, and after the drive time of the winding motor 79 accumulated and added in S23 is initialized, the process ends.

As described above, the winding completion notice is given before all of the polishing cloth 63 is used, so that the amusement arcade or the like can exchange the polishing device 54 with sufficient time. After the winding end notice is given,
If the polishing cloth (polishing tape) update control is performed several times without replacing the polishing apparatus 54, all the polishing cloths 63 are unwound from the reel 64 for unwinding. When all the polishing cloths 63 have been unwound, the dot analog display 105 provided on the front of the pachinko machine 2 is displayed blinking to notify the user.

Next, a control procedure of the winding end control will be described with reference to a flowchart of FIG. First, in S41, it is determined whether or not the end of winding is being notified. If not, the process proceeds to S42, and it is determined whether or not a winding end detection signal is detected. Specifically, the feed amount sensor 152 shown in FIG. 6 determines whether or not the through hole 150a has been detected a predetermined number of times (cumulative number).
