Abstract

PURPOSE:To attain surely the telephone charge management for individual or department, by providing a switch interrupting a DC loop of a line formed of an off-hook of a telephone set to a line connecting section of a managing device, and disabling the correspondence of the line with the said switch when a caller dials without inputting the own code. CONSTITUTION:A magnetic card having a code number is prepared at each department using a telephone set 16 in common. When dialed without inserting a card, a card reader 9 can not detect a code number, but a line interruption switch S is in a state possible for correspondence, then a CPU1 detects an off- hook signal C2 of the telephone set 16. When the telephone set 16 hooks off, a DC loop of lines L1, L2 is formed, the CPU1 detects an off-hook signal C2 to make the line interruption switch S disable state in correspondence to interrupt the DC loop. Thus, the lines L1, L2 are not connected to the telephone set 16.

Description

[Detailed description of the invention] Regarding the method.

Telephone charge management devices that are attached to telephones and that calculate and record the caller's telephone charges are already well known, but when a single telephone is used jointly by multiple people, it is necessary to It is desirable to enter information that is managed by department.・For this reason, it is conceivable that when making a telephone call, the caller inputs his/her Q　code number into the above-mentioned control device, and has the control device record the code along with the calculation result of the telephone charge. .

In order to adopt this idea, it would be mandatory in some way for the above code number to be entered by the caller every time the phone is pressed. Neglecting this duty will result in insufficient charge management that prevents the achievement of the objective.

The present invention provides a method for forcing callers to fulfill their obligations to ensure telephone interest rate management by individual or by department.

Hereinafter, the embodiments of the present invention will be described based on the drawings).

The line cutoff switch (S) consists of two switches (81) (S
2), and at the time of switching, a calling signal detection circuit (20) is connected between the circuit (17) and the divider (19). (21) is a buzzer.

The operation of this device will be explained with reference to FIGS. 1 to 4.

72. Each person who uses the telephone (16) in common before using this Ichiban Sashikin Management Device. During I'J Lent, a 1B Qi card (1B Qi card) is prepared, and the code number for each department is magnetically recorded on the card (by the card reader (9)). shall be.

To make a call, the caller begins by inserting the magnetic card of the department to which he or she belongs into the card reader (9).

At the same time as the cart is inserted, the card reader (9) reads the code number of the card and sends it to the CPU (1) together with the signal (a) in FIG. 3(a) indicating the magnetic card insertion state. c 1] U (], ) is the code symbol It A
M(4) is memorized and displayed on the display (10), and the line cutoff switch (S) is maintained in the state shown in FIG. 2 by sensing the signal (a).

For convenience of explanation - 1 This state of the line cutoff switch (S) is a communication enabled state, and the state where the switch (S) is switched and connected to the ringing signal detection circuit (20) is a communication disabled state, hereinafter referred to as 2. I decided to do it.

To explain this with reference to Figure 3G), during the period of 1υ1 when the "-" sign (a) is being sent out, that is, while the magnetic card is inserted into the card reader (9), communication is always possible. ,
In the space (1) where no magnetic card is inserted, communication is not possible (4).

Insert the magnetic card and turn on the telephone (1G) handset.
When the telephone (16) is turned on, the function of the telephone (16) is activated to issue an off-knock signal (C]) shown in Figure 3 (ρ), and the line (L) is activated.
l) (L2) forms a DC loop via a line cutoff switch (S) and is connected to an intersection (not shown).

Next, by turning the dial, the dialed number is detected by the photocoupler (Pl) of the line connection g13 (11), and if it is a button type, it is detected by the circuit (18), and the dial number is detected by the circuit (18), ) switches the display to the dialed number.

When a call is received or received, Photocabra (L) 2) times +! 1
Il! (L-1) Detects polarity reversal of (L-2> and CI
) U (], ) senses this and starts calculating the telephone charge and displays this on the display (10) at the same time.

When the phone call ends and the handset returns to its original normal state, the telephone switch (1G) goes into the on-hook state (DL), and the telephone charges at this time are stored in the RAM along with the above code number. (4) shall be written and written down integrally.

After telephone line Y, it is a good idea to remove the magnetic card from the card reader (9), but even if you forget this and leave the IBt card inserted, the line will still be cut off (S). The phone remains in perfect condition and there is no problem receiving calls from other phones.

In this way, g (RAM (4)
Stored in A1. Tajoshin 1φ was at the printer (1
In 2), one day's worth or one month's worth is published in the form of a single report or a monthly report, and 1 u story stone money is shown for each 31S gate.

Next, a case will be described in which an attempt is made to make a telephone call without inserting the card reader (4) into the 4-meter car F by mistake.

Since the magnetic card insertion signal (a) is not sent out at this time, the card reader (9) cannot know the code number of the card, but since the line cutoff switch (S) is in the state where intercourse is possible, the OPU ( 1) is in a state where it can sense the off-hook signal (C2) of the telephone (16).

When the handset of the telephone (16) is turned off, a DC loop of lines (Ll) (L2) is formed, and the CPU
(1) thereby senses the off-hook signal (C2) marked in "2" and sets the line cutoff switch (S) to the communication disabled state (el) shown in Fig. 3 H, and interrupts the DC loop marked in "-". . With this, what is the line (LL) (L2)? on the speaker (
16), the connection will be disconnected and the caller will not be able to hear the dial tone and will know that the magnetic card is not inserted.

The communication disabled state (el) continues for a certain period of time, for example, 5 seconds, and then the line cutoff switch (S) is switched to the communication enabled state (■).

If the caller notices that the magnetic card is not inserted during the communication unavailable state (C1) and returns the handset, the line (Ll
) (L2) forms the DC loop, CI)
, U (1) senses the non-formation of the DC loop, maintains the line cutoff switch (S) in the communication ready state (fl), and performs the normal procedure described above, that is, goes off-hook with the magnetic card inserted. Be prepared.

In addition, if a DC loop is formed in the communication enabled state (Jl), the CPU (1) senses the existence of the loop and sets the line cutoff switch (S) to the communication disabled state (C2) again. do.

In this way, the line cutoff switch (S) is in a communication disabled state (cl) (C2) (C3) and a communication enabled state (fl) (
f2) is switched to AC JL, and the switching described in - is continued until it is sensed that the DC loop is not formed in a certain communicable state.

In the communication-disabled state described in 2 above, the telephone device (]0) is disconnected from the line (1.]) (LL), so
Unable to make calls and at the same time 'AC4' from other telephones
I'm in a state where I can't even do ki.

In order to eliminate this inconvenience, please further explain the detection of communications from other telephones in a communication-disabled state and the ability to connect to a line. When communication is disabled, the lines (Ll) (Lz) are connected to the ringing signal detection circuit (2) via the line cutoff switch (S).
Therefore, the calling signal sent from this Shisen's telephone is detected by the -IHI2 calling number detection circuit (20), and at the same time, the detection circuit (20) detects the attached buzzer (21). ) but both CPU (])
inform this.

The example in Fig. 3 shows the case where a calling signal is detected in the communication disabled state (C3), and in the same figure (gl)
(g2) indicates that the buzzer (21) is ringing.

The beeping (gl) (g2) of the buzzer (21) is performed for 1 second at intervals of 2 seconds, and the first beeping (gl) is started at the same time as the above-mentioned ringing signal is detected.

CPU (1) then switches the line disconnection switch ( S) is fixed in a communicable state (f3) and a telephone response is made.

Here, if the fixed time is immediately after the detection of the above-mentioned ringing signal, and the caller of telephone set 1 (1, 6) is on the handset.
- If the caller remains on, the buzzer (21) will hardly be heard, which may confuse the caller.

For this reason, CPU (1) converts the unreliable state (C3) that remains at the time of detecting the call signal to the next fixed intercourse possible state (A
When switching to 3), maintenance is performed to extend the -1-recording unreliable state (C3) depending on the situation so that Jul is always set after 3 seconds have elapsed from the time of the above-mentioned detection.

By doing this, the above caller will always hear the buzzer (21).
Be able to respond after confirming the sound.

-1- First of all, depending on the telephone charge management device described above,
Communication cannot be performed unless the caller's magnetic car F is inserted into the card league (9), so by forcibly registering the caller's code number in the device, telephone charges can be managed. Everything will be safe.

Second, almost at the same time when the handset was put back on, the caller remained in a communicable state (double-line cutoff switch f-(S)), and the caller realized that the magnetic card was not inserted and hurriedly attempted to make a call using the normal procedure. Even in such a case, we can respond quickly and there will be no problem in making the call.

Thirdly, even if the magnetic card is not inserted and the line disconnection switch (S) is off-hook, if a call is received from another telephone, the line disconnection switch (S) will be ready for communication and will respond to the call without delay. .

Fourthly, when receiving such a call, a buzzer must be sounded once or twice (2)
will ring, letting you know that the call has arrived.

It is preferable to keep the communication possible state (fl) (f2) as short as possible, and in some cases, for example, when the calling signal detection circuit (20) and buzzer (21) are omitted, communication becomes impossible. Condition B, 1(el)(e2)(
By making e3) a short time of about 1 or 2 seconds, it may be possible to devise a way to prevent the exchange I-break from mistaking this for the dial-I-Ha issue.

In this example, the line cutoff switch (S) removes (Sl), and (Sl) is a b contact switch, and lt is good.

Also, as a means of entering the code number when communicating,
In addition to using a magnetic card and card soda (9), input operations using a numeric keypad or the like may also be used.

According to the method of the present invention, by forcing the caller to enter his or her own code number when making a telephone call, it is possible to make payments by person or by group. You can do it for sure.
