Description

[Detailed Description of the Invention] This invention relates to a back mechanism panel of a pachinko game machine,
In particular, when a game ball hit into the game board enters the winning area, the mechanism that electrically detects this and pays out a predetermined number of prize balls is electronically controlled, and the falling path of spare balls and prizes are controlled electronically. The ball dispensing device was shifted to one side of the back setting board to enable a large variable prize winning device to be installed in the center, and to smooth the flow of spare balls. Even if a large number of prize balls are generated in a short period of time, the prize ball lead-out path that is equipped with an overflow mechanism and guides the prize balls to a flow path converting section connected to a saucer and an auxiliary saucer is arranged and flowed down a short distance, This invention relates to a back mechanism panel for a pachinko game machine that has a structure that can generate an effective and rhythmic exhilarating sound by causing a prize ball to collide with a bell set in the middle, and that can be used with the recently popular Ratuki Seven type pachinko game machines, etc. .

As is well known, in a pachinko game machine, when a player drives balls into the game board one by one using a firing device installed at the bottom of the game board, they collide with obstacle nails and randomly change direction as they fall. A predetermined number of prize balls are awarded to the player by entering the winning area with a certain probability. Conventionally, the payout of such prize balls has generally been carried out using a first ball, for example, which is attached to the back of the game board and operated by transmitting the physical force generated by the winning balls.
This was done using a mechanical prize ball dispensing device as shown in the figure.

In other words, the back mechanism 22 in the conventional pachinko machine
0 has a structure that is completely and flatly attached to the back of the game board, and above it is a storage tank 224 for spare balls, and connected to this is a storage tank 224 for storing spare balls in an S-shape. A ball chute 225 is separately provided to allow the balls to flow down and line up while flowing down, and a ball ejecting gutter 231 is assembled from the outside in the lower part of the ball chute 225, and a prize ball dispensing mechanism section and a winning ball collection gutter 221 are installed in the center of the back side of the game board. In addition, at the bottom, simultaneous winning balls are stored and separated one by one.
A controller 260 for causing the ball to flow down, and an operating lever 265 that is rotated by the weight of the separated winning balls and faces the winning ball discharge gutter 222 are provided.
The physical force generated by the winning ball is transmitted to the winning ball case 268 provided at the end of the ball chute 225 through an interlocking rod 266 and a link mechanism 267 connected to the end of the ball chute 225. is activated to discharge a predetermined number of prize balls onto a damper 269 disposed below, and further to flow down a prize ball discharge path 236 to pay out the prize balls to a saucer in the front.

Therefore, in conventional pachinko machines, the mechanical structure of the back mechanism 220 provided on the back of the game board is complicated, and assembly and positioning adjustment are troublesome.
The space occupied by the components of the back mechanism 220 becomes large, making it impossible to provide a sufficient empty space at the back of the game board.

On the other hand, among recent pachinko machines, those that have a large variable prize winning device that uses an electric drive source to create a condition in which a large number of prize balls are awarded, so-called "Ratsuki Seven", have become popular among players, and most Machines are increasingly being equipped with large variable prize winning devices. However, in such large-scale variable winning machines, the electric drive source often extends through the game board to the rear of the back setting board, so they are not equipped with a conventional mechanical prize ball dispensing device. However, with such a back mechanism, there is a disadvantage that there is not enough space to extend such a variable prize winning device.

Furthermore, with the adoption of such a large-scale variable winning device, the chances of simultaneous or consecutive winning balls occurring are extremely increased. However, in the conventional mechanical prize ball dispensing mechanism, the dispensing operation is a mechanical link motion as described above, so one dispensing cycle is approximately
It takes 1.5 seconds, but with current electric launchers it takes 1.5 seconds.
100 balls are fired per minute. That is, 0.6
As the ball is launched into the game board every second,
There is a risk that a large amount of prize balls will be generated in a short period of time, and the payout of prize balls will not be able to keep up with the number of winning balls, and the winning balls will accumulate one after another. Therefore, a high-speed prize ball dispensing device is desired, and smooth flow of spare balls and prize balls is desired.

However, in the conventional back mechanism as shown in FIG. 1, the ball chute 225, which aligns and guides the spare balls in the storage tank 224 to the prize ball case 268 at the center of the back of the game board, is meandering. In addition, the prize balls discharged from the prize ball case 268 may not flow down smoothly, and the prize balls ejected from the prize ball case 268 may
69 and then flow down the prize ball ejection path 236, the ejected prize balls will scatter on the damper 269,
It takes time for the liquid to flow into the saucer. Therefore, for example, if the last ball you have during a game falls into the winning area that gives you a special benefit, even if the variable winning device called Atatsuka, which increases the chance of winning, opens, it is already in the receiving tray. The lack of balls and the slow payout of prize balls often caused players to become frustrated.

Therefore, the hanging part of the spare ball's falling path and the prize ball payout device were shifted to one side of the back setting board on the back of the game board to form a wide space in the center, which made it possible to install a large variable prize winning device. At the same time, we have made the prize ball dispensing device electric and made the spare ball flow path simpler than before to smooth the flow of the balls, and we have also placed the prize ball delivery path on the sloping upstream side of the saucer. Therefore, we considered shortening the distance that the prize balls reach the saucer so that a large amount of prize balls can be dispensed in a short time.

However, if the prize ball outlet is provided on the upstream side of the tray in this way and the distance from the prize ball dispensing device to the prize ball outlet on the upstream side of the tray is shortened, the prize ball will be removed from the bell provided in the middle of the prize ball outlet. It becomes difficult to cause the balls to collide effectively and generate an exhilarating sound. In other words, in order to increase the sound generated by the bell, it is necessary to increase the falling speed of the prize ball, and to do so, the prize ball outlet path must be of a vertical structure. On the other hand, in order to generate an even, rhythmic sound with the bell, it is necessary to align the prize balls and let them flow down, but as mentioned above, in order to make the sound of the bell louder, the prize ball outlet path is made completely vertical. However, there is an inconvenience that the prize balls falling apart will fall apart. In addition, since the prize ball outlet path is shortened, if a piano wire or the like is inserted from the prize ball outlet upstream of the saucer, it will easily reach the prize ball dispensing device and illicitly operate it to remove the spare ball. There is a risk that the act will become easier to carry out.

The present invention was made against the background as described above, and provides an electric prize ball payout device that is operated based on a winning detection signal generated by electrically detecting a batted ball that enters a winning area. By adopting this, the complicated and excessive mechanical configuration of the controller 260, operating lever 265, and interlocking rod 266 in the back mechanism is unnecessary, and the entire back mechanism, which mainly includes the prize ball dispensing device, can be configured compactly. At the same time, the hanging part of the prize ball flow path and the prize ball dispensing device are offset to one side of the back setting board, making it possible to form a wide space in the center and smoothing the flow of spare balls. Accordingly, by providing a prize ball lead-out path on the inclined upstream side of the saucer, the prize balls can reach the tray from the prize ball dispensing device in the shortest distance, even if a large number of prize balls are generated in a short period of time. The purpose is to enable prompt extraction to a saucer.

In addition, the present invention provides a structure in which the prize ball lead-out path has a structure in which the first rectifying section having an appropriate slope, the substantially vertical rapid current section, and the second rectifying section are vertically connected, so that the prize ball can be drawn out over a short distance. This makes it possible to rectify the prize ball and increase its speed, thereby making it possible to generate an effective and rhythmic exhilarating sound from the bell provided in the prize ball exit path, and to prevent the entry of piano wires, etc. The purpose is to make it difficult to prevent fraud.

Further, the present invention provides a prize ball dispensing device so as to communicate the outlet of the prize ball dispensing device with a flow path converting section that is provided with an overflow mechanism and forms a branch area of two types of flow paths that are connected to the receiving tray and the auxiliary receiving tray. By providing the ball lead-out path, when the saucer becomes full of prize balls, the prize balls will quickly overflow from the flow path converter to the auxiliary saucer, and the bell provided in the prize ball lead-out path will be activated. To prevent an exhilarating sound from being filled with prize balls and no longer generating an exhilarating sound.

FIGS. 2 to 4 show an overall configuration diagram of an embodiment of a pachinko game machine according to the present invention. The pachinko game machine 1 is rotatably attached to a machine frame 2 (see FIG. 3), which has open front and rear surfaces, while maintaining a substantially vertical posture and using hinges 3, 3 shown in FIG. A picture frame-shaped front frame 4, a glass storage frame 5 attached to the front frame 4 so as to be openable and closable, an opening/closing panel 6 similarly attached to the lower part of the glass storage frame 5 so as to be openable and closable, and the front frame 4. It consists of a glass plate held in the glass storage frame 5 behind the glass storage frame 5, and a game board 8 fixed at a constant distance.

A saucer 9 for temporarily storing a large number of elastic balls (so-called pachinko balls) is provided on the front surface of the opening/closing panel 6, and a saucer 9 is provided on the lower back surface of the front frame 4, where balls are supplied one by one from the saucer 9. A ball launcher 10 is provided for knocking off an elastic ball, and an operation dial 11 and an auxiliary tray 12 are provided on the lower front surface of the front frame 4. The above batted ball launcher 1
0 has the same configuration as a known ball launcher, so a detailed explanation will be omitted.

On the front side of the game board 8, the ball launcher 1 is installed.
A guide rail 13 that guides the ball hit by the player 0 to the upper part of the game board 8, and a large number of obstacle nails 14 that randomly change the direction of the ball falling from above are fixedly installed. A winning chaser 15, a winning opening 16, a rotary winning device 17, and a variable winning device 18 are provided as a winning region, and are surrounded by a guide rail 13 in a space between the glass plate held on the front frame 4. A gaming section is formed. In addition, at the bottom of this gaming section, the above-mentioned prize area 15 is placed in the corner as it falls from above.
An out hole 19 is provided to collect the batted balls that do not win a prize to the rear of the game board 8.

On the back side of the game board 8, a back setting board ₂₁ is attached to the entire surface so as to form a first space A1 having an interval where winning balls from the winning areas 15 to 18 can flow down. Various mechanisms constituting the back mechanism board 20 are set on the back side of the back setting board 21 in a superimposed manner.

Below the first space _A1 of the back setting board 21,
A collection shelf 21a is provided, and a winning ball ejection path 22 is provided approximately in the center thereof so as to be continuous with the first space _A1 .
is formed, and the winning balls that enter the first space _A1 flow down there and are discharged outside the machine.

The collecting shelf 21a, which is formed to slope downward toward the center, rectifies the generated winning balls one by one in a row and guides them to the winning ball discharge path 22, and detects winning balls attached on the way. 1 in 55
The individual destinations are detected and sequentially stored in a storage circuit within the control device 50 set above the rear setting board 21.

Further, in the first space _A1 , an out ball trough 23 is provided corresponding to the out hole 19, and is configured to discharge out balls to the outside of the machine.

Above the surface of the back setting board 21 is a preliminary storage section 2 for storing spare balls supplied from the outside.
4 is attached, and as shown in FIG. 5, by fixing the preliminary storage section 24 so as to sit on the back setting board 21, the structure is such that it can withstand the weight of the preliminary balls. An outflow port 24a is provided on one side of the downwardly inclined tip of the preliminary storage section 24, and below this outflow port 24a, the back setting board 21 is inclined to such an extent that the balls roll from the left to the right under its own weight. A guide path 25 is provided which is bent downward at the right end and then descends substantially vertically, and the terminal end of this guide path 25 is connected to the inlet of the prize ball dispensing device 40.

As shown in FIGS. 5 and 6, the guideway 25 is provided on the back surface of the back setting board 21 so as to form a gutter-shaped second space _A2 , and has a bottom portion facing the outlet 24a. A treadle lever 26 is provided so as to be tiltable, with one end protruding into the guideway 25 and a weight 27 attached to the other end. A vessel 56 is placed in front of it. This detects the presence or absence of balls in the preliminary storage section 24, and when there are no balls, it issues a ball shortage signal and contacts the general management office (not shown).
This is to encourage the replenishment of balls.

Further, the guiding path 25 is provided so that the partition wall 25a gradually rises so as to automatically align and guide the spare balls in one row and two rows. They are lined up.

In the middle of the taxiway 25, the ball pressure in the taxiway 25 changes slightly depending on how well the balls are stored in the preliminary storage part 24, and the balls overlap in two or three stages to prevent the ball from stopping. In order to prevent this, a swingable ball holder 28 is suspended, and a ball holding plate 29 is provided which can be tilted by pivoting one end thereof.

A ball removal mechanism 30 is disposed at the bent portion 25b of the guiding path 25, and a socket of the ball removal path 31 is made to face. The bent portion 25b is provided with a peripheral wall portion 32 that can open and close a portion of its outer peripheral surface, a swinging rod 33 that swingably holds the peripheral wall portion 32, and an operating rod 34 that can freely tilt above the wall portion 32. The locking portion 33a of the swinging rod 33 and the convex portion 34a of the operating rod 34 are configured to engage with each other, and by releasing the engagement by an external operation, the peripheral wall portion 32 is opened and the spare ball is released. It is designed to lead to Tama-Nukiro 31.

The ball extraction passage 31 is arranged in parallel with the guide passage 25, and the lower part of the passage is bent and buried toward the first space _A1 , and extends to the lower part of the pachinko machine 1. The spare ball is configured to be taken out of the machine.

Then, a flow abnormality detector consisting of a detection plate 57a and a micro switch 57b facing into the flow path for each row is arranged in the middle of the substantially vertically descending portion of the guideway 25. Abnormalities in the flow of the spare balls due to stuck balls or dirt or the like are monitored, and a command signal is output to the control device 50.

The electric prize ball dispensing device 40 connected to the guideway 25 is composed of a sprocket 42 and a pulse motor 41 as a driving source, as will be described in detail later as an example, and is mounted on the back side of the back setting board 21 and one side. It is miniaturized so that it can be placed on the side.

The prize ball payout device 40 is a device that pays out a predetermined number of prize balls to the player when a ball hits the entered prize area and receives a signal from the winning ball detection path 55 in the entered prize ball ejection path 22. The sprockets 42 are rotated one after another by a drive command signal generated based on the number of sprockets 42 until a predetermined number is reached.

Therefore, when an abnormality in the flow of the spare balls as described above is detected in the guideway 25, the control device 50
At that point, the ejection of the prize balls is stopped, or until the ejection operation is completed, that is, until a predetermined number of prize balls are ejected, and the next ejection is stopped. By lighting a warning lamp such as an LED display element, the cause of the malfunction can be immediately identified and prompt measures can be taken. It is designed to reliably prevent balls from getting caught in the sprocket 42 due to misalignment.

Below the prize ball dispensing device 40, a prize ball lead-out path 3 having a structure as shown in an enlarged manner in FIG. 8 is provided.
6 is a flow path conversion path 38 that communicates with a discharge gutter 44 as a discharge port of the prize ball dispensing device 40 and the saucer 9;
It is set up to communicate with. That is,
This prize ball outlet path 36 includes a rectifying section 36a connected to the discharge gutter 44 and inclined at an angle of about 15 to 50 degrees;
Consisting of a rapid flow section 36b that hangs down in a substantially vertical direction from the terminal end of this rapid flow section 36a, and a second flow rectification section 36c that is inclined from the terminal end of this rapid flow section 36b in a direction opposite to the rectification section 36a. A bell 37 is disposed at the lower end of the second rectifier 36c so that the left half of the bell 37 faces the inside of the outlet path from the upper end.

Therefore, the prize balls discharged from the prize ball dispensing device 40 are aligned by the first rectifying section 36a and flow down, are accelerated by their own weight in the rapid flow section 36b to increase their speed, and then are flown again. Second rectifier 3
6c, and 4 from the upper end of the bell 37.
Halfway through, they start colliding properly from the tangential direction. Therefore, the bell 37 generates a loud sound due to the prize balls accelerated in the rapid flow part 36b, and also generates an even rhythmic sound by colliding the prize balls aligned in the rectifying parts 36a and 36c. Moreover, in this case, the prize ball is Bell 37.
Since the ball collides with the upper quarter, it produces a more exhilarating sound than when colliding with other parts, and since it collides with the bell 37 from the tangential direction, there is less bounce even if it hits, and the ball bounces after the collision. The water quickly flows down toward the flow path conversion section 38 below without being dispersed.

As shown in FIG. 7, the flow path converting section 38 provided at the lower end of the prize ball outlet path 36 converts the flow path by about 90 degrees to communicate with the tray 9 on the front of the pachinko machine near the bell 37. The auxiliary saucer 12 at the lower front of the pachinko machine is formed so as to extend the prize ball outlet path 36 diagonally downward.
By communicating with a branch gutter 39 connected to the flow path, a branch area of two types of flow paths is formed.

As shown in FIG. 7, the flow path converting section 38 is provided with a connecting gutter 46 that penetrates the first space A ₁ and the game board 8, and a connecting gutter 47 connected to the connecting gutter 46. It is communicated with the prize ball outlet 9a of the saucer 9 through. As shown in FIG. 9, this prize ball outlet 9a is provided on the inclined upstream side of the saucer 9, and the prize balls flowed into the saucer 9 flow down on this and are aligned at the rectifier 9b. Then, they are fed one by one through the opening 9c to the guide rail base on the front of the game board.
That is, the prize ball dispensing device 40 and the prize ball outlet path 36 are attached to the back setting board 21 in advance so as to be deviated to one side of the inclined upstream side of the receiving tray 9. As a result, the distance from the outlet of the prize ball dispensing device 40 to the outlet 9a of the saucer 9 is shortened, and the time required to pay out the prize balls is shortened. In addition, 9
Reference numeral d designates an operating lever provided to cause the balls in the tray 9 to flow directly into the auxiliary tray 12.

Furthermore, the flow path conversion section 38 includes a branch gutter 39.
A regulating piece 48 that protrudes upward is provided at the boundary between the two to form an overflow mechanism. That is, this regulating piece 48 normally directs the prize balls flowing down the prize ball outlet path 36 to the diverter gutter 39.
However, when the space from the saucer 9 and the connecting gutter 47 to the flow path conversion part 38 becomes full of prize balls, the prize balls automatically climb over the regulating piece 48 and flow into the diversion gutter 39. The structure is such that the water overflows and flows out toward the auxiliary saucer 12 below. As a result, a large number of prize balls can be stored without bothering the player, and it becomes possible to use the recently popular Ratuki Seven type pachinko game machine.

Further, as shown in FIG. 8, on the wall surface of the bent portion of the prize ball lead-out path 36, there are obstructing protrusions 7 that protrude downwardly or diagonally downwardly.
1, 71,... are formed, and the prize ball lead-out path 3
Coupled with the fact that 6 is formed in a substantially S-shape,
As shown by the chain line D in the figure, even if the piano wire is inserted from the prize ball outlet 9a of the saucer 9, the obstruction protrusion 71
By blocking the player from entering the prize ball dispensing device 40, fraudulent activities such as unauthorized operation of the prize ball dispensing device 40 can be prevented.

Furthermore, on the upper wall of the lower end of the prize ball lead-out path 36,
As shown in FIG. 8, a guide piece 72 protruding toward the flow path conversion section 38 is provided either integrally with the wall surface or as a separate member, and the prize ball flows down inside the prize ball outlet path 36 and collides with the bell 37. The prize ball may be prevented from flowing directly into the diversion gutter 39 with its force. In this case, by making the guide piece 72 an elastic member, the speed of the prize ball flowing down can be slowed down by the guide piece 72, and when it falls to the bottom of the flow path converting section 38, it will fall apart. It is also possible to quickly change direction and flow into the receiving tray 9 without being dispersed.

FIG. 10 shows the electric prize ball dispensing device 40.
FIG. 2 is an enlarged perspective view showing an example of the configuration.

As shown in the figure, the terminal end of the taxiway 25 is bent diagonally downward and has two exit sections 25 _{c
1,25 c2} are provided. This outlet part 25 _c1 ,
25 Separation sprocket 4 facing _c2
A sprocket 42 is fixed to the rotating shaft of a pulse motor 41, and a blocking plate 43 is fixed to the motor 41 at an appropriate distance from the sprocket 42. Further, on the outer periphery of the sprocket 42, for example, six recesses 42a and six claws 42b, which can be engaged with pachinko balls, are formed. Exit section 25 _c at the end of the taxiway 25
₁ and 25 _c2 , when one side faces the concave portion 42a of the sprocket 42, the other side faces the claw portion 42b.
It is configured to face the

Then, the blocking plate 43 and the outlet portion 25 _c1 , 2
5. It is positioned so as to have a distance of one ball from the end of _c2 , and a discharge gutter 44 connected to the upper end of the prize ball outlet path 36 is provided below it.
The prize ball B that came into contact with the claw part 42b was locked so that it would not flow out, and the prize ball B' that engaged with the recess 42a came into contact with the blocking plate 43 and was held between it and the following prize ball B''. After that, when the sprocket 42 rotates, it is separated by the pawl portion 42b and is allowed to flow down into the discharge gutter 44 below.

Further, an L-shaped notch is formed in the blocking plate 43, and as shown in FIG. 11, an ejected ball detector 45 including a plurality of sensors 45a to 45d is provided in this notch. . Above sensor 4
Among 5a to 45d, 45a and 45d are the outlet part 2
Sensors 45c and 45d are for detecting whether there is a ball to be ejected next in 5 _c1 and 25 _c2 , and confirming whether the ball has been ejected. It can be configured using a proximity switch.

The prize ball payout device 40 is configured so that the winning detection signal outputted from the entered prize ball detector 55 is transmitted to the control device 50.
When supplied, the motor 41 is driven by the drive signal output from the control device 50 and starts discharging. At this time, the control device 50 starts discharging after confirming that the spare balls are present at the exit of the taxiway 25 based on the detection signal from the discharged ball detector 45, and also receives a prize from the discharged ball detector 45. Upon receiving a discharge confirmation signal output for each ball, the discharge state is detected, and upon determining that a predetermined number of prize balls has been reached, a discharge end signal is output to the prize ball dispensing device 40, and the rotation of the motor 41 is stopped. I'm starting to let them do it.

As explained above, the present invention has the advantage of mounting the prize ball dispensing device and the hanging portion of the prize ball downward path to one side of the back setting board, forming a wide empty space in the center, and forming a large variable winning device. A display device, etc. can be attached, and the flow of spare balls is smoothed, and a prize ball lead-out path is provided on the inclined upstream side of the saucer, so the prize balls can reach the tray from the prize ball dispensing device in the shortest possible distance. In this way, even if a large number of prize balls are generated in a short period of time, they can be quickly drained into the tray, and this has the effect of making it possible to deal with the recently popular Ratuki Seven type pachinko machine. be.

In the above embodiments, the explanation has been made using a back mechanism panel that has an electronically controlled prize ball dispensing device, but the present invention provides a back mechanism panel that has a mechanical prize ball dispensing device on one side. Of course, it can also be applied to

Further, in this invention, the prize ball outlet path has a structure in which the first rectifying section having an appropriate slope, the substantially vertical rapid current section, and the second rectifying section are vertically connected, so that the prize ball can be flowed over a relatively short distance. The prize balls can be efficiently rectified and flowed down at an increased speed, which not only allows for smooth and quick payout of the prize balls, but also enables effective delivery of the prize balls from the bell facing the prize ball delivery path. Moreover, it is possible to generate a rhythmic and refreshing sound.

Furthermore, by attaching the bell so that about half of one side from the top of the bell faces into the prize ball outlet path, and arranging the prize ball to collide with the upper quarter of the bell from a tangential direction, an exhilarating bell sound can be produced. It is possible to prevent the balls from dispersing after the collision by reducing the bounce of the prize balls, and to quickly flow them out to the receiving tray through the flow path conversion part.

In addition, since the prize ball lead-out path is formed by vertically connecting the first rectifying part, the rapid current part, and the second rectifying part, the prize ball is detoured in an approximately S-shape as a whole. It is possible to make it difficult for the piano wire or the like inserted from the prize ball outlet of the saucer to enter the prize ball dispensing device above, and fraudulent acts can be prevented. Furthermore, by forming obstructing protrusions at appropriate locations such as bends in the middle of the prize ball lead-out path, it is made more difficult for piano wires and the like to enter, thereby reliably preventing fraudulent activities.

Further, the present invention provides a prize ball dispensing device so as to communicate the outlet of the prize ball dispensing device with a flow path converting section that is provided with an overflow mechanism and forms a branch area of two types of flow paths that are connected to the receiving tray and the auxiliary receiving tray. Since the ball outlet path is provided, when the tray is full of prize balls, the prize balls can quickly flow from the flow path converter to the auxiliary tray, allowing a large amount of prize balls to flow out without bothering the player. The prize balls can be stored, and the bell provided in the prize ball outlet path can be prevented from being filled with prize balls and no exhilarating sound can be generated.

In the above embodiment, the bell is provided at the lower end of the second rectifying section 36c constituting the prize ball outlet path, but it may also be provided a little further upstream, for example, in the middle or at the lower end of the rapid flow section 36b. . However, the lower the bell is placed, the louder the bell sound can be made.
