Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is based on the response of the called party! The present invention relates to an improvement in a public telephone set which is equipped with a charging timer that operates as 1.1 and which collects call charges in accordance with periodically generated multi-collection signals.

[Prior art]

In general, public telephones (hereinafter referred to as telephones) have a fixed number of ground seconds depending on the destination area when long-distance calls are allowed, and the exchange sends out a charging signal every time this number of seconds elapses. In the past, there was a multi-station charging system that collected a fixed amount of unit call charges, or a separate application filed by the present applicant entitled "Distance-based time difference charging device for public telephones" (1973-
131741) discloses that a terminal multi-charging system is adopted in which a telephone independently generates a multi-collection signal every time seconds above ground elapse, and a fixed amount of unit call charges are collected based on this signal.

However, in the station multi-charging system, a discount rate is set for calls made to remote areas during late night hours and public holidays, and the period of the charging signal sent from the exchange is It is determined that it will be long.

However, due to the terminal multi-charging system, the charging signal from the switching system does not arrive, so the charging timer installed in the telephone starts operating in response to the called party's response, and the multi-charging signal is periodically generated. , discount rates are not set, which creates a drawback that is uneconomical for users.

[Summary of the invention]

The present invention has the object of fundamentally solving all the drawbacks of the conventional art, and detects the destination area number f from the dialed calling number after off-hook, as well as the timekeeping of the clock means for timing at least the time and day of the week. content) and during the discount period η・
Based on this result and the destination area code, the unit call charge or fc is calculated based on a charging constant such as the number of ground seconds, and based on this charging constant and the multi-collection signal from the charging timer. This is an extremely effective public phone that collects call charges and allows users to receive discounts on charges even though it is a multi-terminal billing system.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to figures showing embodiments.

Figure 1 is a block diagram of the entire configuration, and the incoming call detection circuit 3 is always connected to the line terminal 1 to which the line from the telephone office is connected via the contact g81 of the relay GS provided in the main unit 2. When this unit detects the arrival of a calling signal, it drives the buzzer 4 and sends the incoming call information to a processor (hereinafter referred to as CPU) such as a microprocessor via an input/output circuit 5a and a motherboard 6. It is supposed to be given to and started.

Further, when the hook switch 8 generates off-hook information due to off-hook, the start circuit 9 responds and the relay G

The control data stored in the Read Only Memory () is used as necessary.

That is, in the case of a call, the signal generator 18 sends out a dialing signal using a complex audio frequency in response to the operation of the keyboard 17, the display circuit 19 displays the call charge, etc., and when the called party answers, a dial signal is sent from the exchange. Sorting and storage of various coins such as low denomination, medium denomination, and high denomination coins by the sub unit 20 and coin storage mechanism (hereinafter referred to as storage mechanism) 21 according to the response information given by the billing signal receiving circuit 101 in response to the non-transfer pulse. When transmitting dial signals, the dialer can be used to send out free calls depending on the data in the EPROM, and to allow free calls or stop calling prohibited numbers depending on the data in 10P R081. The unit call time elapses according to the data in the EPROM, according to the timekeeping contents of the clock circuit 22 which has a calendar function that measures the time, day of the week, and holidays, and the multi-accumulation signal generated by the charging timer configured in the CPU. Each time, the coins corresponding to the unit call charge are stored, and when there are no more coins waiting, the handset 14
In response to this, the signal generator 18 sends out all the stress tones and also performs the forced disconnection of the call.

On the other hand, in the case of an incoming call, the relay GS is driven according to the off-hook information from the hook switch 8, the DC loop is completely closed, and the call is permitted, but the incoming call detection circuit 3
Based on the incoming call information from fC, the CPU7
makes a judgment and does not perform the above-mentioned controls.

The sub-unit 20 also includes a redundancy measurement circuit 23 which is connected to each sensor provided in the storage mechanism 21 to detect the material, outer diameter, thickness, etc. of the inserted coin, and which records the measured value of the coin. A 7'C EPROM 24 is provided to store the upper and lower limit values of the measured values determined by the coin sorting data as coin sorting data, and the measurement circuit 23 is stored in the EFROM via the input/output circuit 25.
28 is directly connected to the bus 6, and the CPU 7 determines whether the inserted coin is correct or not according to the measured value from the measuring circuit 23 and the coin sorting data in the EPROM 24, and also controls the storage mechanism via the input/output circuit 25. control 21,
It is used to return irregular coins, accumulate and store regular coins, etc.

Note that control data etc. are also stored in the EFROM 24 as part of the call processing program, and the EPR
It is used together with the call processing program in OM 15 to regulate the control operation of the CPUr.

In addition, a printed circuit board or the like is used for each unit 2.20, the sub-unit 20 is combined with a storage mechanism 21, and the space between the sub-unit 2o and the main unit 2 is extended from the sub-unit 20. The cord and the plug connected to the tip of the cord are electrically connected to the connector 26 of the king unit 2 in a detachable manner.

Also, 'T' switch 2 can be used as a call charge display switch.
If you operate this, this operation information will be sent to C.
The PU7 receives it via the input/output circuit 5a, and the keyboard 1
Even if 1 is operated, the dialing signal is not sent at all, and the call rate per unit call time corresponding to the number dialed is displayed in its entirety by the display device 19, so that no call is made in the event of a disaster. You can check the call charges.

It should be noted that if the user operates the keyboard 17 while off-hook without operating the 'T' switch 27, a dial signal will be sent, but a similar display will be displayed in this case as well.

However, this unit call time is determined as an operationally reasonable time, such as 3m1n, and the corresponding call charge is determined by the CPU 7 detecting the destination area code from the dialing number and It is determined based on the number of seconds over the ground for the destination area number, and is determined by a table key search method using a table, which will be described later, stored in the EPROM 24.

Note that the means for calculating call charges etc. using a table is disclosed in a separate application filed by the present applicant [Call frequency display device J (Japanese Patent Application No.
4-48050), which may be substituted with the call charges for the number of seconds shown in Table 3.

According to Y of 114, it corresponds to the displayed call charge by giving priority to low denomination coins, etc.! Coin storage process ``115'' is performed, and based on the detection output from the sensor for checking the storage status of the storage mechanism 21, judgment is made ``Is the condolence storage defective?''116'e, and if this is N'''C, is the Hayabusa on hook?'' 11γ is N. Yes, 1 charge timer/time amplifier? ``When 118 becomes Y, the process returns to step 112 and repeats the process from here on.

In addition, in step 115, if coins with an amount exceeding the call charge are stored, the difference in the call charge is calculated, and this difference is added to the total amount of accumulated coins, and becomes the subsequent "-amount used", or , if the difference is greater than or equal to the call charge, repeat step 11 until the difference is less than the call charge.
In step 5, storage of coins is omitted.

Also, l'J 'E in step 114 or step 11
At 6 Y, the process moves to - ``Send emphasis tone'' 121,

Judgment is made from 1 to 403, and depending on N of this,
Step 404, which is the same as step 205 in FIG. 3, is performed, and if any of these is Y, step 405, which is the same as step 20B in FIG. Call charges apply.

Therefore, on public holidays, holidays, and during discount hours such as 8:00 p.m. to 7:00 p.m., a discounted call charge is automatically applied and the call charge is collected accordingly, which is extremely advantageous for the user. Become.

Then, arrange all the unit call times according to the destination area in the table shown in Table 1, store this in the EPROM 24, and set the unit call time as a charging constant in the step of ``determining the charge for each call'', The charging timer setup time may be changed accordingly.

In addition, in FIG. 2, steps 106 to 109 may be inserted before step 104 to check that the unused amount is greater than the call fee when the called party answers, and step 104 may be The same result can be obtained even if dialing is prohibited at the switch Y and step 131 is omitted.
In Fig. 2, steps can be replaced or unnecessary steps can be changed depending on the situation, such as keeping the transmitting state disabled until step 116 reaches N and performing the same process in response to step 103 Y. It can be omitted, and the same applies to FIG.

In addition, in FIG. 1, the power supply circuit 12 may not be used, and another power source such as a commercial power source may be used. It is the same if you ignore things other than waiting for a caller response, and the coins used may be of a single type or of multiple types, and in the case of multiple types, the coins may have a common storage track and coin slot, or may have separate coin slots. Any of these may be used, and the present invention can be modified in various ways, such as not only the front loop method but also the rear loop method for closing the DC loose.
