Abstract

PURPOSE:To allow facsimile equipment which performs facsimile transmission under the control of a keyboard and calculates the charge for the transmission to control the charge perfectly by disabling the facsimile transmission when origination from a telephone set is detected. CONSTITUTION:A control circuit 3 reads a transmission destination telephone number out of a storage device 7 with a signal from the keyboard 6 and drives a relay 12 to switch telephone circuits L1 and L2 to the side of an automatic dial device 14, performing dial origination. When a transmission key is operated, the circuit 3 drives a relay 11 to switch the circuits L1 and L2 to the side of a facsimile transmitter and receiver 1, which sends out a signal obtained by scanning the transmit original. The circuit 3 operates a timer circuit 8 to counts the time up to the stop of transmission, and the telephone charge table stored in memory 5 is referred to on the basis of the counted value and distance data calculated from a telephone number to calculate the transmission charge. When a telephone set 13 originates, the circuit 3 disables the operation of the facsimile transmission key with the detection signal from a polarity detecting circuit 16.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a facsimile machine equipped with a communication charge calculation function.

(B) Prior art Recent facsimile machines have a communication charge calculation function that stores call charge table data, determines communication distance from the telephone number data of the communication destination, and calculates communication charges based on the communication time. There are some systems that are equipped with a system, which has the effect of allowing charge management for each department.

However, in the conventional system, although it is possible to calculate charges for dialing calls made using the dialing circuit of a facsimile machine, charges cannot be calculated for calls made from a telephone, and complete charge management cannot be performed. The problem was that there was no.

(C) Object of the Invention The object of the present invention is to provide a facsimile apparatus which can solve the above-mentioned problems and perform complete charge management.

(D) Structure of the Invention The present invention is configured to monitor the polarity of the telephone line and detect whether or not a call has been made from the telephone, thereby disabling the transmission operation if the telephone is able to make a call. It is.

This circuit detects the polarity reversal of (L2), and is composed of two photo couplers (17) (1g) connected to the telephone line (L'l) (L2) as shown in Figure 2. The output signal (S1) (S2) is supplied as a polarity detection signal to the control circuit (3) via the OR gate (19) as a polarity detection signal. A control circuit (3) IC is supplied as a control circuit (3).The control circuit (3) hooks up the handset of the telephone (13) and connects either photocoupler (L1) or (L2) depending on the polarity of the telephone line (L1)
17) When the occurrence of a hook-up signal is detected by the operation of a certain ull;
The potential of S2) is detected, and if it is different from the first stored '1', it is determined that a call has been made from the telephone (13).

Next, the operation of the present invention having such a configuration will be briefly explained.

First, prior to use, the 1F phone number 5'-ta of the main communication destination is entered from the keyboard (6) and stored in advance in the device path (7). And in standby state l/)-
t: is the relay contact (2>(2') and (15) (15
') is switched as shown in drawing G, and the telephone (13
) or telephone lines (L 1) (L 2).

Therefore, if the facsimile automatic reception mode has been set using the keyboard (6), when the incoming call signal detecting circuit (10) detects an incoming call signal, the control circuit (3) is activated by the relay (11). ) is driven and - contact (2

2), the received iPhone code is decoded and recorded by the recording unit, and reception is performed. When the reception is completed, the relay contacts (2) and (2') are restored, the telephone line is disconnected, and the standby state can be restored.

When transmitting next time, first set the original to be sent and then enter the telephone number of the communication destination using the numeric keys on the keyboard (6), or read the telephone number data stored in advance in the storage device (7) and make the call. When operated, the control circuit (3) that has taken in the telephone number data is activated by the relay (12).
) to switch the relay contact <15) (15') to the automatic dialing (14) side, and the automatic dialing device 14
> to make a dial call. When the transmission key is operated after the transmission is completed, the control circuit (3) drives the relay (11) and switches the relay contact (2>(2') to the transmitting/receiving section (1) side, and the scanning section scans the original to be sent. After processing the read data such as encrypting it, it is connected to the telephone line (Ll>
(L2).

At this time, the control circuit (3) starts a built-in timer counter to start counting the communication time at the same time as the transmission starts, and stops the timer counter and stops counting the communication time when the transmission ends. Then, when the transmission is finished, based on the communication start time data set by the clock circuit (8>) and the distance data determined from the telephone number, the unit time data stored in the memory (5>) is read out, and the communication time is counted by the timer counter. The communication charge is calculated from the above and displayed on the display (9), and is also stored in the storage device (7).

When dialing is made using the keyboard (6) in this manner, charges are calculated and charges can be managed upon completion of the communication.

Next, an explanation will be given of the operation when attempting to make a dial call and send a message using the telephone (13).

In this case, even if the telephone (13) makes a call, the control circuit (3)
Since charges cannot be calculated using ``Phone A (13)'', transmission is not possible when a call is made using telephone a (13). That is, the telephone (1
3) When the handset is hooked up, the polarity detection circuit (
Either one of the photo couplers (17) and (18) of 16) is operated, and either of the output signals (31) (S2) is ORed.
It is supplied as a hook-up signal to the control circuit (3) via the gate (19). The control circuit (3) that detected the hook-up signal outputs the output signal at that time (the potential of S2 is r
Remember whether it is H or "L" level. and a telephone (13
), and when the other party answers, the line (
Since the polarity of Ll>(L2) is inverted and the potential of the output signal (S2) is also inverted, the control circuit (3) detects that the potential has changed from the initially memorized potential, and the telephone (13) makes a call. It is determined that the send key has been sent, and subsequent operation of the send key is disabled.

Therefore, even if you make a dial call, you cannot send a message. However, it is possible to do this by just talking.

If the manual reception mode is set and there is an incoming call, the phone (13) will ring and the handset will answer, but the incoming call will hook up the handset and connect the phone line <LL>. Since the polarity of <L2) is not reversed, there is no change in the potential of the detection signal <92), and the receive key on the keyboard (6) can be operated, allowing manual reception.

Note that communication charges can be managed reliably by appropriately recording the collected communication charges in the storage device (7) separately for each reading department.

(f) Effects of the Invention As described above, the facsimile device of the present invention is capable of automatically calculating the communication charge after the end of the communication when dialing based on the telephone number data entered from the keyboard of the facsimile device. However, if a dial call is made using a telephone that cannot calculate charges, the system is configured to disable the transmission operation, and the communication charges can be managed reliably, which has a great practical effect.
