Abstract

PURPOSE:To move to normal telephone set operation immediately when a storage magnet is normal at the time of off-hook action by providing a control means which operates plural latch type magnets into initial state in order unless legal money passed through coin selection parts is detected by a 2nd detecting means. CONSTITUTION:The public telephone set is equipped with a coin diameter sorting part 3 which detects and sorts the diameter of a coin 1, a coin material sorting part 4 which sorts the material, and a storage detection LED 10 (2nd detecting means) which detects storage. Then when the legal coin 1 passed through the coin sorting parts 3 and 4 is not detected by the 2nd detecting means 10, the latch type magnets 9 are operated into the initial states in sequence and only if a latch type magnet 9 is defective in operation at the time of off-hook action, it is operated into its initial state. Consequently, when the latch type magnets 9 are normal, the normal telephone set operation is immediately entered by the off-hook action.

Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a public telephone that detects the operational status of a plurality of latching type magnets for accumulating coins, and performs recovery control of these when the malfunction occurs. It is something.

[Prior Art] In general, in public telephones powered by a central office power system, a latch type magnet used for accumulating coins has an undefined direction of operation when off-hook and supplied with central power. FIG. 5 shows the operating direction of this latch type magnet. Figure <a) of the same figure shows the reverse I state of this macnet, and Figure (b) shows its operating state. In this way, in the restored state, the coin, i.e. the coin, is stored in the latch type magnet (hereinafter referred to as the storage magnet).
When the storage magnet 9 is activated, the storage lever 11 is activated as shown in the figure, and as a result, the coin 1 can be stored. I can't do anything but stir it. Since the operating state of the storage magnet 9 cannot be detected, conventionally, when off-hook and when the station power is supplied, the storage magnet 9 is moved in the recovery direction regardless of whether the storage magnet 1-9 is operating. I am trying to initialize it to .

In other words, since multiple storage magnets 9 are installed in this public telephone so that multiple types of coins 1 can be stored, initializing these magnets 9 at the same time is limited. Since this is not possible with the local power supply, initialization is performed one by one in sequence. 1 [Problem to be Solved by the Invention] L-17,':, public telephones from VC systems are capable of sequentially attaching a plurality of storage magnets I, one at a time, regardless of whether the storage magnets are in operation or not. Since the initialization is in the direction of recovery, until this initialization process is completed, the phone will not be able to perform its original operation even if the storage magnet is working normally, and therefore the phone will not be able to be used during this time. There is a problem:.

[Means for Solving the First Problem] Second, the first invention of the public telephone according to the present invention to solve such problems includes a first detection means for detecting an inserted coin, and a first detection means for detecting an inserted coin, and a first detection means for detecting an inserted coin; a second detection means for detecting; and control for sequentially operating the plurality of latch type magnets to an initial state when an IF coin detected by the first detection means and passed through the coin sorting section is not detected by the second detection means. It is equipped with means.

Further, the second invention includes a first detection means for detecting an inserted coin, a third detection means for detecting a returned coin, and a coin detected by the first detection means; passing through the π wing part. and a control means for sequentially operating the plurality of latch-type makunetsu 1 to the initial state when a genuine coin is detected by the third detection means. .

Further, the third invention includes means for setting a failure mode of the public telephone when the genuine coins that have passed through the coin sorting section are not detected by the second detection means or when the genuine coins are detected by the third detection means. It is something.

Further, the fourth invention is provided with means for releasing the loop for a certain period of time when the public telephone becomes a malfunctioning mote.

Further, the fifth invention includes a counting means that counts the number of failures when the public telephone enters a failure mode and is reset by an accumulation confirmation output from the second detection means or the third detection means, and a hook. and means for holding the faulty motor setting means by outputting a constant value from the counting means regardless of the state.

In a sixth aspect of the present invention, a plurality of latch type mucknets are used as a mucknet for storing a plurality of coins individually.

[Operation] When a genuine coin that has passed through the coin sorting section is not detected by the second detection means, the plurality of latch type magnets are sequentially operated to the initial state.

Further, when a genuine coin passing through the coin sorting section is detected by the third detection means, the plurality of latch type magnets are sequentially operated to an initial state.

Further, the failure mode is set when the genuine coins that have passed through the coin sorting section are not detected by the second detection means or when they are detected by the third detection means.

Furthermore, when the public telephone goes into failure mode, the loop is opened for a certain period of time.

Also, when a public telephone enters a failure mode, the number of failures is counted from 1 to 1, and this failure count is reset by the accumulation confirmation output from the second detection means or third detection means, and the number of failures is set to a fixed value. When this failure mode is reached, this failure mode is maintained.

[Example] Next, the present invention will be explained with reference to the drawings.

Next, FIG. 2 is a block diagram showing an embodiment of the public telephone of the present invention. In this figure, parts equivalent to those in FIG. 1 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

That is, this public telephone has a line terminal L2 to which the telephone line from the exchange is connected, a hook switch H3I - billing signal receiving circuit 2], a diode bridge 2
2. A communication loop is formed through a power supply circuit 23 and a forced disconnection circuit 24, and a communication circuit 25 is connected to this, and the transmitter T and receiver R of the handset 26 are connected to this.

Additionally, a control section 27 consisting of a microprocessor, memory, etc. is provided, including a billing signal receiving circuit 21, two coin processing sections for sorting, accumulating, and storing coins 1, a dial key 30, a hook switch H82, etc. Control-F is determined according to each output, and controls the two coin processing units, the display unit 32, the MP signal generator 33 that generates MF and other signals, the telephone call circuit 25, the forced disconnection circuit 24, etc. It becomes.

Note that the M, F signal generator 33 responds to the output of the dial key 30 and the control of the control unit 27, and
An MP multiplied signal is generated in accordance with the operation of the MP multiplied signal, and is sent out as an MP multiplied signal signal via the communication circuit 25.

On the other hand, in the power supply circuit 23, when the hook switch H3' is turned on due to the off-hook, a DC loop is closed via the communication circuit 25, and a loop current with a constant polarity is passed through the diode block 1 lunge 22. This charges the capacitor and supplies the terminal voltage of the capacitor to various parts as a power source.

Therefore, in the first loop' method, when the off-footer is performed, the DC loop is closed, and the control unit 27 sends out a permission signal in response to the output of the two coin processing units due to the insertion of the coin 1. It becomes possible to make a dial call using the dial key 30, and the call can be made freely depending on the response from the other party.

In addition, when a polarity inversion pulse equal force billing signal arrives from the exchange in accordance with the response of the other party 1jll, this is received by the billing receiving circuit 21, and a receiving 1Δ output is generated and sent to the control unit 27. The control unit 27 controls the two coin processing units to store the coins 1, and if there is not enough =l in 1 that has been inserted and is waiting, the forced disconnection circuit 2
4, the DC loop is released for a certain period of time 7, the exchange is restored, and the call is forcibly disconnected.

The display unit 32 is configured to remind you to insert coins, to display a shortage of coins 1, and to display that coins cannot be used due to an abnormality in the storage status. .

Next, the operation when the coin storage function of the public telephone which operates as described below becomes defective will be explained in detail based on the flowchart of FIG.

First, if you go off-hook from a public phone, Ste Knob 5
At step 51, this public telephone J\ station power is turned on, and then in step 51, this public 'iE telephone is activated.Next,
The trouble flag cell 1-", which will be described later, will tell you whether or not this public Y ('-'42 phone is out of order).
is detected and judged, and if it is determined that this hook is not connected to the cell 1 and there is no malfunction, then the step 53
The input of coin 1 is determined by detecting the ON state of the output of input detection IJI) 2. If the insertion of coin 1 is not detected and it is determined that it is N-1, the on-footer detection is determined in step 54, and if on-hook is detected, the forced disconnection circuit 24 is activated in step 55. The DC loop is opened and the process ends. Also, the on-footer is not detected and in step 54 [NJ and 'l:11
If the request is rejected, other processing is performed in step 56 and the process returns to step 53.

After that, the coin 1 is inserted, and if it is determined in step 53 that it is Yl, the process moves to step 60, and the inserted coin 1 is inserted into the coin diameter sorting section 3. Coin material sorting section 4 etc. C;:
Then, a coin sorting process is performed, and then in step 61, passing detection is performed by passing the coin 1. Determine whether ED7 is on. 7. Then, the above differential processing was performed =! If in1 is 1 coin, passing detection 1. E D 7 is passed, and as a result, this or the other is turned on, and in step 61 it is judged as [Yl. After that, in step 62, accumulation detection 1. , I"
: I) Determine by detecting ON of JO. In other words, =1 in 1 is accumulated by the accumulation I/bar 11 of the accumulation magnet 9, which accumulates individually at i'' according to this type, and when coin 1 is accumulated here, each Corresponding accumulation detection 1.E I) '10.

However, due to a defect in the storage magnet 9, etc., the rechargeable coin 1 is not detected due to accumulation detection ■-5E D ] 0 etc. Step 6
”, the failure flag is set to 1 with the step knob 63, and then the failure is displayed on the display unit 32 in step 6A. Thereafter, in step 65, the forced disconnection circuit 24 is driven to open the loop for a predetermined time (1 second), and in step 66, N (four in this embodiment) storage magnets l-9 are sequentially restored. and step 67.
Then, the value of a failure counter that counts the number of failures of this public telephone is incremented by one, and the process moves to step 68/\\, where it is determined whether the value of this failure counter has reached a fixed value (1-).

Even if the storage magnet 9 is moved in the recovery direction as described above, the subsequent on-hook/off-hook operation and the insertion of a coin will cause the storage magnet 9 to
is still malfunctioning, and as a result, in step (,)8, the value of this lti counter reaches a constant value [-
If it is determined that this is the case, the public telephone is determined to be out of order (1-5), and the subsequent normal telephone processing is performed.In step 69, only the first hook-up is detected and determined. In this way, when on-hook is detected, the fault flag and the fault display are held as they are without being cleared, and the process moves to step 55. In step 55, the forced disconnection circuit 24 is driven to open the DC loop. and exit. If it is determined in step 68 that the value of the failure counter is less than a certain value, a determination is made to detect an on-footer in step 70, and if an on-footer is detected, the failure flag is reset in step 71, and then Step 72
In step 55, the failure display displayed on the display unit 32 is cleared, and in step 55, the loop is opened and the process ends.

In addition, if coin 1 can be accumulated normally, the accumulation detection LED 1. Based on the off detection output of O or the on detection output of return detection LE'Dt5, which will be described later, step 6
If the determination in step 2 is ``Y'', the failure counter is cleared in step 73), then coin accumulation processing is performed in step 74, and the process returns to step 53 in preparation for the next coin 1 insertion.

In addition, if on-hook is performed when it is determined in step 68 that the value of the failure counter has reached a certain value, as described above, the 1;* flag is not reset, and the In this case, if the public telephone goes off-hook again, it will not be able to repair the malfunction again. Since this has not been completed, it is determined in step 52 whether the failure flag is set or "Y", and a failure is displayed, and at step 81 only the on-footer detection is determined without performing normal telephone processing. If this occurs and on-hook is detected, the fault indication is cleared in step 82, followed by the DC loop being opened in step 55.

Next, FIG. 4 is a flowchart illustrating the operation of another embodiment of the public telephone of the present invention. In the same figure, the third
Portions equivalent to those in the flowchart in the figure are given the same reference numerals, and their explanation will be omitted.

That is, the flowchart of FIG. 4 provides a step 90 instead of the ON detection determination of the accumulation detection LEDIO in step 62 of the flowchart of FIG. It is configured to determine whether the return detection LED 15 is on. Therefore, the other operations are
The operation is completely equivalent to the operation in flowchart 1 in the figure.

As explained above, the present invention counts a failure counter when the inserted coin 1 is not accumulated, and if the value of this failure counter is less than a certain value, the DC loop is forcibly disconnected for a predetermined time, and The storage magnet 9 is sequentially operated in the recovery direction, and if the storage magnet 9 cannot be restored and the value of the failure counter reaches a certain value, a failure display will be displayed at all times indicating that repair is required, and the storage magnet 9 will be activated. This prevents normal telephone processing from occurring until normal recovery is achieved.

[Effects of the Invention] As explained below, the public telephone according to the present invention is capable of detecting genuine coins that have passed through the coin sorting section when they are not detected by the second detection means or when they are detected by the third detection means. Since multiple latch type magnets are operated sequentially to the initial state, when the latch type magnet is off-hook, it is operated to the initial state only when the latch type magnet is malfunctioning.
Therefore, if the latch type magnet is normal, it has the effect of immediately returning to normal telephone operation by going off-hook.

Furthermore, the failure mode is set when a genuine coin that has passed through the coin sorting section is not detected by the second detection means or when it is detected by the third detection means.
This has the effect of being able to identify whether the latch type magnet is operating correctly or not.

Also, when a public telephone goes into failure mode, the loop is opened for a certain period of time, the number of failures is counted, and when this number of failures reaches a certain value, this failure mode is held. If the off-off is turned off while the failure mode 1~ is held, a failure display is performed, and as a result, there is an effect that it is possible to immediately identify whether there is a failure in the telephone bill.
