Abstract

PURPOSE:To improve the operability of a facsimile equipment in regard of its communication procedure by storing the communication information and its registration data of a receiver on the transmitter side and detecting coincidence of stored registration data between the transmitter and receiver sides for execution of the communication control. CONSTITUTION:In a transmission state where the transmitter side performs the calling by means of the one-easy-step or abbreviated dialing, a CPU 3 refers to an abbreviated procedure operation flag included in a RAM 5 and sends the register date to the receiver side by means of a non-standard function setting signal (NSS) and via a MODEM 2 and a network controller 1. At the receiver side, the registering/updating dates set at its own equipment and received by the signal NSS after a circuit is caught is compared with the date registered in its own equipment. When the coincidence is confirmed between both dates, an acknowledge signal is transmitted. Then a receiving processing is carried out based on the reception pointing instruction produced at the transmitter side. Thus it is possible to previously know at the transmitter side that the communication information on each receiver is changed and also to effectively use the communication time.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine.

[0002]

2. Description of the Related Art By storing communication information such as destination name and image transmission speed for each destination registered in one-touch dial or speed dial, the destination name can be described in a communication management report or communication can be performed. Shortening time has been done with conventional fax machines.

[0003]

However, in the prior art, there was no means for judging whether the communication information of each receiver stored by the transmitting side at the time of communication was coincident with the data of the current receiver. If there is a change in the communication information, the communication information of each receiver on the transmitting side may differ from the registration data on the receiving side, which may be inconvenient. In order to solve such a problem, the present invention aims to improve usability in a communication procedure by comparing the communication information of each receiver previously stored by the transmitter side by communication with the current status of the receiver. To aim.

The operation of the embodiment will be described with reference to FIG. First, the operation on the transmitting side will be described with reference to FIG. For transmission in which the transmitter side makes a call using one-touch dial or speed dial, the flag is turned on by referring to the speed-up operation flag 21 of the speed-up operation information 12 of the one-touch / speed-dial inside the RAM 5 of FIG. In this case, it means that the information of the receiver is stored, so that in FIG.
1) Set the communication timer (S2), registration date and time 24 in FIG.
Is transmitted using a non-standard function setting signal (hereinafter referred to as NSS) (S3), and a response signal reception waiting state (S3, S4, S
7, loop of S11). When an affirmative response signal is received in S4, a reception command is transmitted and the T.S. According to the procedure of 30, when the training signal and the like are transmitted and then the reception preparation confirmation signal is received, the image signal is transmitted (S6). The procedure thereafter is the same as the conventional T. Perform the procedure indicated by 30 or the like. The above timing chart is shown in FIG.

When DIS is received from the receiver in S7 of the response signal reception waiting state of FIG. 4, the transmitter receives D.
The receiving command is transmitted by the IS, and the conventional T.S. After the training signal and the like are transmitted in accordance with the procedure of 30, when the reception preparation confirmation signal is received, the image signal is transmitted (S9). The procedure thereafter is the same as the conventional T. Perform the procedure indicated by 30 or the like.
The above timing chart is shown in FIG.

When no signal is received from the receiver in S11 in the waiting state for the response signal and the timer is set and the time has elapsed, the line is disconnected (S13) and the transmission process is terminated.

Next, the operation on the receiving side will be described with reference to FIG. After the line is captured (S20), the receiver side sets the reception timer (S21) and shifts to a command waiting state (loop of S22 and S29) for a certain period of time.
If you receive the registration / update date and time for your
The date and time received in S24 is compared with the date and time registered in the own device, and if they match, an affirmative response signal is sent (S2
At the same time as 6), reception processing is performed according to the reception instruction command on the transmitter side (S27). The above timing chart is shown in FIG.

If there is no match in S24 of FIG. The reception mode of No. 30 is entered (S28).

When no signal is received from the transmitter in S29 in the command waiting state and the time set in the timer has elapsed, the line is disconnected (S31) and the transmission process is terminated.

(Other Embodiment) The operation of another embodiment will be described with reference to FIGS. First, the operation on the transmitting side will be described with reference to FIG. The transmitter side refers to the shortened procedure operation flag 21 of the shortened procedure information 12 of the one-touch / abbreviated dial in the RAM 5 of FIG. 2 in the transmission for making a call using the one-touch dial or the shortened dial, and the flag is turned on. In this case, since the information of the receiver is stored, the transmitter sets the communication timer after making a call (S41) in FIG. 7 (S42), and transmits the shortened procedure signal using NSS (S43). ), A waiting state for receiving a response signal (S43, S
44, loop of S53). When the registration / update date and time on the receiver side is received in S44, it is compared with the registration / update date and time on the receiver side stored on the transmitter side (S46).
If they match (S47), a reception command is sent and the conventional T.S. After the training signal and the like are transmitted according to the procedure of 30, when the reception preparation confirmation signal is received, the image signal is transmitted (S49). The procedure thereafter is the same as the conventional T. Perform the procedure indicated by 30 or the like. The above timing chart is shown in FIG.

In S47 of FIG. 7, if the dates received from the receiver do not match, a date / time mismatch signal is sent (S50), and the phase B DIS waiting state is entered (S51).

The procedure thereafter is the same as that of the conventional T.S. Perform the procedure indicated by 30 or the like. The above timing chart is shown in FIG.

When no signal is received from the receiver and the timer elapses in S53 in the response signal reception waiting state, the line is disconnected (S55) and the transmission process is terminated.

Next, the operation on the receiving side will be described with reference to FIG.

After the line is captured (S60), the processing on the receiver side is
The reception timer is set (S61), and a command waiting state for a fixed time (loop of S62 and S70) is entered, and S6
When the shortening procedure signal is received by the NSS in 2, the registration / update date and time of the own device is transmitted (S64), and the process shifts to the response reception waiting state (loop of S67 and S70). At this time, if the receiving command is received from the transmitter side (S68), the receiving process is performed according to the previous receiving command (S69). The above timing chart is shown in FIG.

If a date / time mismatch signal is received in S65 of FIG. The mode shifts to the reception mode of 30 (S7).
0). The above timing chart is shown in FIG.

When no signal is received from the transmitter in S70 in the command waiting state and the time set in the timer elapses (S70), the line is disconnected (S72) and the reception process ends.
