Description

[Detailed description of the invention] [Field of industrial application] The present invention is configured to store one or more coins at the same time in response to a single charge coin storage signal in a public telephone that uses both local power and commercial power. The present invention relates to a coin storage mechanism, and more particularly to a coin storage mechanism that can store a desired number of coins and secure a call state at a public telephone even when a commercial power supply is interrupted.

[Conventional technology]

Conventionally, in the coin storage mechanism of the coin sorting device attached to public telephones that use only the central office power supply, which is generally well known, the storage lever is moved in response to the coin storage signal sent from the central office equipment. Since the coin storing mechanism is configured to store one coin by operating the coin only once, there is a need for the development of a coin storage mechanism that can store a plurality of coins, for example, two coins at the same time. However, on the other hand, it is not a good idea to manufacture a coin storage mechanism that can store multiple coins at the same time with a single storage operation, as the number of coin storage mechanisms increases, and it is not a good idea to manufacture coin storage mechanisms that can store multiple coins at the same time. It is desired that the device be constructed so that it can be used not only for personal use but also for storing a single sheet, thereby providing versatility.

For this reason, the coin storage mechanism of coin sorting devices attached to public telephones that use central office power and commercial power (for example, 100 VAC) has conventionally used a control section operated by commercial power to A configuration is adopted in which two pulse signals are sent out in response to a one-charge coin storage signal from the controller, and the coin storage lever is operated, for example, twice to sequentially store two coins, and the control section is changed as appropriate. This is effective in that it can be used for storing two sheets or for storing a plurality of sheets at the same time.

[Problem that the invention attempts to solve]

However, with such public telephones that use both local power and commercial power, in the unlikely event of a power outage to the commercial power, users will be unable to use the public telephone, resulting in a decline in public service. There is a risk that this may occur, and there is a need to take some countermeasures. Of course, if it is used to store a single coin, it is possible to operate the storage lever with a single charge signal from the station to ensure a callable state, but it is also used to store multiple coins at the same time. In such cases, it is difficult to deal with such problems, and there is a demand for a coin storage mechanism that takes such problems into consideration during power outages.

[Means for solving problems]

The coin storage mechanism according to the present invention includes a coin storage lever having upper and lower stoppers facing into the track alternately at the terminal end of the coin storage track, and a first coin storage lever for coin return forming a track wall at the terminal end of the track. and a second lever having an auxiliary stopper that is pivotally supported on the first lever and projects within the track to a position opposite to the upper stopper of the storage lever by an electromagnetic device operated by a commercial power source. , these first and second levers are configured to be detachable using fastening members such as screws.

[Effect]

According to the present invention, when storing one sheet, the first and second levers are connected with a fastening member such as a screw,
These are made to operate integrally independent of the electromagnetic device, and on the other hand, in the case of storing multiple sheets at the same time,
The first and second levers are made independent by removing screws, etc., and the auxiliary stopper of the second lever is projected into the track by an electromagnetic device, and during a commercial power outage, the auxiliary stopper of the second lever is By leaving the orbit, a plurality of coins can be stored at the same time using a single charge coin storage signal.

〔Example〕

Hereinafter, the present invention will be explained in detail using embodiments shown in the drawings.

1 to 3 show an embodiment of the coin storage mechanism according to the present invention, and in this embodiment,
High denomination coins (100 yen coins) and low denomination coins (10 yen coins)
In a coin sorting device that uses local power and commercial power, the coin sorting device has two input slots arranged side by side on the same plane and a coin track and a return track on the same board. Only the coin track on the side is shown, and the track on the high-value coin side and other attached members are not shown.

In these figures, what is designated by reference numeral 1 is a board installed upright in a telephone housing (not shown), and at its upper end there is a slot member 4 having high and low denomination coin slots 2 and 3. It is attached. 5 is the substrate 1
The flapper is pivotally supported on a support shaft 6 supported between both sides of the input port member 4 so as to face the upper end side, and when a transmitter/receiver (not shown) is picked up, the biasing force of a spring 7 is applied. is biased to face the board 1 at a predetermined interval, and between each coin slot 2,
It is configured to form a coin passage from 3 to 3. In addition, when the handset is hooked on a foot lever (not shown), an operating lever 8 that is linked to the foot lever (not shown)
(See Fig. 2), the part 5a of the flapper 5 is rotated in the direction away from the base plate 1, thereby opening the flapper 5 and allowing the inserted coin to fall onto the coin return track 9 side. It is configured. In addition, in the figure, 8a is a roller part that operates integrally with the operating lever 8, 8b is a roller part that presses a part 5a of the flapper, and 10a and 10b are the outer diameter and thickness of the coin from each input port 2 and 3. The coin rail for sorting, 11 is a lightweight coin sorting lever, and other material sorting mechanisms (not shown) are arranged in the coin passage formed by this board 1 and flapper 5 to form a coin sorting track. are doing. Further, in the figure, reference numeral 12 denotes a spring that biases the operating lever 8 in the direction of removing the timer and receiver, and 13 denotes a coin rail mounting bracket member.

Reference numeral 14 denotes a side plate fixed at a predetermined interval below one side of the substrate 1 via spacer members 15a to 15e, and these substrate 1, side plate 14, and spacer members 15a to 15e are arranged in the coin sorting orbit described above. A coin accumulation track 16 is formed in which regular coins sorted by are accumulated. This coin accumulation trajectory 1
6 has an inclined track section 16A whose upper end is continuous with the coin sorting track on one side of the board 1 and is inclined toward the center of the board 1, and from its lower end reaches the bottom of the board 1 in a substantially vertical state. It is composed of a vertical track section 16B.

The lower end side of the coin accumulation track 16, that is, the vertical track section 16B has a first coin (X ₁ in FIG.
A coin storage lever 17 having a lower stopper 17a for locking the coin storage lever 17 (shown in ) is rotatably supported on the back side of the base plate 1. This coin storage lever 1
7 is driven by a polarized relay (not shown) which is energized by a control section controlled by a commercial power supply that sends a billing pulse signal for a desired number of coins in response to a coin storage signal sent from the telephone office at regular intervals. , is rotatably supported in a direction perpendicular to the substrate 1 via a bracket 18 fixed on the substrate 1 and a support shaft 18a, and is bent so that its lower end protrudes into the track 16. stoppa 17
It constitutes a. In addition, a second coin (indicated _by The first and second upper stoppers 17 that lock the
b, 17c are provided. In addition, 19 in the figure
A and 19b are rollers with coin detection contacts that look into the coin accumulation track 16 from one side and detect the presence or absence of accumulated coins.

On the other hand, on the terminal side of the coin accumulation track 16, the upper stopper 17b of the storage lever 17,
On the other side of the track 16 opposite to 17c, a first lever 20 having a locking piece 20a facing into the track 16 so as to form a coin accumulation track wall is rotatably supported on the back side of the base plate 1. The locking piece 2 is held by the spring 12 via the roller portion 8a of the operating lever 8 with which the upper end 20b engages.
0a is always biased to face inside the orbit 16. When this engagement is released, that is, when the handset is hooked on the handle lever, the locking piece 20a is moved by the action of the spring 22 wound around the support shaft 21a of the support bracket 21.
is configured to exit from the track 16 and return the accumulated coins to the return track 9 side. In addition, 2 in the figure
0c is provided integrally with this first lever 20,
Like the locking piece 20a, this portion forms a part of the coin accumulation track wall.

Now, according to the present invention, the first lever 20 is supported substantially in the center by the support shaft 23, and the spring 24 wound around the support shaft 23 is used to move the lever 20 away from the base plate 1. a second lever 26 having an auxiliary stopper 26a projecting within the coin accumulation track 16 to a position opposite to the upper stoppers 17b, 17c of the storage lever 17 by an electromagnetic device 25 which is energized and operated by a commercial power source; is provided, and this second lever 26 is connected to the first lever 20.
On the other hand, it is characterized in that it is configured to be detachable using a screw 27 as a fastening member. Incidentally, reference numeral 30 in FIG. 1 is an opening formed in the board 1 for inserting a driver for attaching and detaching the screw 27.

That is, when the storage lever 17 is in the storage operation, the auxiliary stopper 26a of the second lever 26 cooperates with the upper stopper portions 17b and 17c to pinch the second coin X ₂ from both sides thereof. , which serves to temporarily lock within the coin storage track 16. Of course, this first coin
When the storage operation of X ₁ is completed and the storage lever 17 returns to its original state, the second coin X ₂ that is temporarily locked falls down within the track 16 and hits the lower stopper of the storage lever 17. It will be locked at 17a.

In the above-described configuration, when this coin storage mechanism is used for storing one coin, the first
As shown in FIG. 3, the first and second levers 20 and 26 are integrated with a screw 27, so that the auxiliary stopper 26a of the second lever 26 always faces inside the coin accumulation track 16. It is a good idea to leave it there. In this way, the storage lever 17 is swung in response to a coin storage signal from the station, and the coins are stored one by one, thereby maintaining the talking state of the telephone. Such a storage operation is the same when the commercial power supply is turned on and during a power outage, and in either case, it is possible to ensure a state in which a call can be made. {Figure 4a,
Refer to b} That is, when the handset and receiver are hooked on the handle lever, the first lever 20 is attached to its locking piece 20.
a, 20c have left orbit 16,
Following this, the auxiliary stopper 26a of the second lever 26 is also in a retracted state. On the other hand, when the handset is removed and a coin is inserted, the first and second levers 20 and 26 rotate integrally, and the locking piece 20
a, 20c and the auxiliary stopper 26a are connected to the track 16.
It becomes a state of being inward. And at this time, the second
As is clear from FIGS. 4a and 4b, the lever 26 is completely unrelated to the interlocking lever 28 that is interlocked with the armature 25a of the electromagnetic device 25 operated by the commercial power source. In this case, the fourth
Fig. 4a shows the state in which one bill per charge is stored while the commercial power supply is on, and Fig. 4b shows the state in which one charge per charge is stored during a commercial power outage. Also, when the handset is hooked to the hook switch during a call, the flapper 5 is released and the first and second
The levers 20 and 26 are rotated in the direction of leaving the track 16, and the excess accumulated coins are returned, and the coin storage lever 17 is also moved in the same manner by the recovery lever indicated by the reference numeral 29 in FIG. It will be restored.

The electromagnetic device 25 described above is generally configured to operate the coin return lever on the high-value coin side, which makes it impossible to make calls using high-value coins in the event of a power outage to the commercial power supply. Since its configuration and the like are not directly related to the present invention, a description thereof is omitted.

On the other hand, when the above-described coin storage mechanism is used for storing a plurality of coins, in this case two coins, at the same time, the screw 27 is removed and the first and second levers 20 , 26 may be separated so that they can operate independently. At this time, the second lever 26 is connected to the spring 24
is rotated in a direction away from the track 16 independently of the first lever 20.

However, in the above-mentioned configuration, as long as the commercial power supply is on, these first and second levers 20 and 26 can operate integrally as in the case of storing one sheet as described above. That is, when the handset is picked up, the first lever 20 rotates toward the track 16 so that its locking pieces 20a and 20c face inside the track 16, and the electromagnetic device 25 is also excited, so that its armature 25a and Interlocking lever 2
8, the second lever 26 is also rotated toward the track 16, so that its auxiliary stopper 26a faces into the track 16, as shown in FIG. 5a. When the user inserts a plurality of coins and the coins are accumulated in the orbit 16, the control unit controlled by the commercial power supply described above sends out two charging signals in response to the single charging signal from the station, and the coins are stored in the track 16. The lever 17 swings twice,
It stores the coins one by one and becomes ready for talking.

On the other hand, when the commercial power supply is in a power outage state, the electromagnetic device 25 becomes de-energized, and as a result, as shown in FIG. The state will be as follows. In this state, when the one charge signal from the station arrives and the coin storage lever 17 operates to store only once, the first coin X ₁ is stored, and then the second coin X ₂ is also stored. The coins are stored and dropped without being locked, so that two coins can be stored at the same time and a state in which calls can be made can be ensured. This is the auxiliary stopper 26
It is easily understood that since the width of the track 16 is widened to such an extent that it is impossible to prevent coins from falling, since the track 16 does not protrude into the track 16. Of course, the third and subsequent coins (only X ₃ is shown) are stopped by the upper stopper 17c of the storage lever 17 and the upper locking piece 20c of the first lever 20, and when the storage lever 17 is rotated to recover. Then, it falls to the position of the lower stopper 17a, and the same operation will be performed sequentially thereafter. And, this kind of simultaneous storage operation of multiple sheets is
This also works effectively even if the commercial power supply fails during a call. It goes without saying that if the number of sheets inserted is insufficient, the sensor detects this condition and the storage lever 17 remains inactive.

The present invention is not limited to the structure of the embodiment described above, and the shape and structure of each part may be modified and changed as appropriate. Furthermore, in the case of storing multiple coins at the same time, it is not necessary to store two coins. Of course, three or more coins can be stored at the same time by changing the length of the coin storage track, etc.

Further, in the above-described embodiment, a case has been described in which the screw 27 is used as a fastening member that detachably configures the first and second levers 20, 26, but the present invention is not limited to this. It goes without saying that any member may be used as long as it can detachably fasten the lever member.

[Effect of idea]

As explained above, according to the coin storage mechanism according to the present invention, the first lever for returning coins is supported on the base plate so as to form a track wall on the terminal end side of the coin storage track, and the first lever An auxiliary stopper that projects within the coin storage track at a position opposite to an upper stopper of the coin storage lever that projects when storing coins is provided by an electromagnetic device that is supported on a shaft and biased away from the board and operated by commercial power. Since the second lever is configured to be detachable from the first lever using a fastening member, it can be used for single storage despite its simple and inexpensive configuration. It can also be used to store multiple sheets at the same time, making it highly versatile, and even in the event of a commercial power outage, it can ensure call status without any problems, greatly improving service to users. It has various excellent effects.

In particular, according to the present invention, by simply attaching and detaching fastening members such as screws, a single model can be used for both single-sheet storage and multiple-sheet storage simultaneously. It is possible to prevent an increase in the number of models, and it also has sufficient countermeasures against power outages of commercial power supplies, which has the advantage of excellent operational reliability and further advantages in terms of production planning and inventory management.
