Abstract

PURPOSE:To reduce the facsimile communication time by allowing a transmitter to send facsimile reception data in the memory reception and memory substitute reception at a maximum capability of the minimum transmission time. CONSTITUTION:A main control section 11 commands start of a transmission control procedure to a communication control section 16 and commands decision processing of a received form to a reception form control section 14. The reception form control section 14 reports the reception form information from a recording section state noticed from a recording control section 12 to a communication control section 16 and a decoding control section 15. Then the communication control section 16 sets a minimum transmission time to 0 msec in the case of the memory reception and intercepting reception, and sets the minimum transmission time to a time required to record one line of the receiver in the case of recording paper reception and sends an initial identification signal to a destination transmitter. Moreover, the decoding control section 15 transfers the coded data transferred from the communication control section to the recording control section 12 in the case of recording paper reception and transfers the coded data transferred from the communication control section to a picture information storage section 13 in the case of the memory reception and intercepting reception.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having a document receiving means, and more particularly, an image information storing means,
The present invention relates to a facsimile apparatus having both means for recording image information.

[0002]

2. Description of the Related Art Conventionally, in the case of accumulating and receiving in the image information accumulating means in this kind of facsimile apparatus, the same uncompressed data 1 as in the case of receiving the minimum transmission time of the DIS signal on the recording paper is used.
The recording time for the line was set and the data was sent to the other transmitter.

[0003]

In the conventional facsimile apparatus described above, the minimum transmission time of the DIS signal is set to the same one-line recording time as when receiving and storing the image information in the image information storage means. Since the minimum transmission time of the receiver tends to be longer than the minimum transmission time of the transmitter because it is transmitting to the other transmitter, communication is performed in the minimum transmission time of the receiver in the personal class facsimile machine. It will be.

In one example of a personal class facsimile, the minimum transmission time of the transmitter is 10 ms / line and the minimum transmission time of the receiver is 20 ms / line, so that the minimum transmission time of the receiver is Tends to be slower.
Further, the time for accumulating one line of data when accumulating and receiving in the image information accumulating means is 0.1 msec / line,
It can be seen that it is considerably shorter than the recording time for one line.

Therefore, the conventional facsimile has a drawback in that the communication time cannot be shortened because the communication is performed in the minimum transmission time of the receiver even when the image information storage means stores and receives.

The present invention has been made in view of the above-mentioned conventional circumstances, and therefore, an object of the present invention is to eliminate the above-mentioned drawbacks inherent in the conventional technology and to store and receive facsimile-received data in a memory. Another object of the present invention is to provide a novel facsimile apparatus capable of shortening the facsimile communication time by transmitting the minimum transmission time of the image signal with the maximum capacity of the transmitter in the memory proxy reception.

[0007]

In order to achieve the above object, a facsimile apparatus according to the present invention comprises a line control means for switching a connected line between a facsimile side and a telephone side, and a partner facsimile and transmission control. Communication control means for executing the means, image information storage means for storing compressed data, recording control means for recording non-compressed data on recording paper,
Decoding means for converting the compressed data into non-compressed data, and reception mode for storing the compressed data received from the partner facsimile in the image information storage means or similarly on the recording paper by the recording control means. The reception mode control means determines the state of the recording control means notified by the means, and the main control means for controlling the various means to control the reception of the facsimile document.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the accompanying drawings, as a preferred embodiment thereof.

FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus according to the present invention.

Referring to FIG. 1, one embodiment of the present invention is
Main control means 11, recording control means 12, image information storage means 13, reception mode control means 14, and decoding control means 1
5, the communication control means 16 and the line control means 17.

Next, the operation of the facsimile apparatus according to the present invention will be described with reference to FIG. 1. When there is a call from a partner transmitter (not shown) for transmission of a facsimile document, the line control means 17 The main control means 11 is notified that there is a call. The main control means 11 notified of the call instructs the line control means 17 to switch the line to the facsimile side and also instructs the communication control means 16 to perform facsimile communication procedure control, and further controls the reception mode. The means 14 is instructed to determine the reception mode.

The reception mode control means 14 instructed to determine the reception mode determines the reception mode by taking the status information of the recording control means from the recording control means 12. When the state of the recording control means is such that recording is not possible due to the absence of recording paper, or when it is a memory proxy reception, etc., the reception mode control means 14 determines that the image information accumulating means 13 is accumulating and receiving, and the recording state. When the information is normal, it is determined that the recording paper is received on the recording paper. Receiving form control means 1 which has decided the receiving form
4 notifies the decoding control means 15 and the communication control means 16 of the reception form information.

The communication control means 16 sets the minimum transmission time of the DIS signal to one line recording time in the case of recording paper reception according to the reception form information notified from the reception form control means 14. In addition, in the case of storage reception to the image information storage means 13, it is set to 0 milliseconds.

When the DIS signal set as described above is sent from the communication control means 16 to the partner transmitter, the partner transmitter receives the minimum transmission time notified by the DIS signal from the receiver and the minimum transmitter itself. The transmission time is compared, and the faster minimum transmission time of the two minimum transmission times is determined as the minimum transmission time of the communication to be performed.

When the minimum transmission time of the DIS signal received from the receiver is set to 0 msec, the partner transmitter does not have the minimum transmission time of 0 msec, and therefore the minimum transmission time of the transmitter itself. Decide to communicate with.

When the facsimile communication procedure shifts to the transmission of image information, the decoding control means 15, which has already been notified of the reception mode information from the reception mode control means 14, transfers the compressed data from the communication control means 16, When receiving the recording paper, the transferred compressed data is converted into non-compressed data and transferred to the recording control means 12. The recording control means 12 records the transferred non-compressed data. Repeat this 1
Record the received data for a page.

Further, in the case of storing and receiving in the image information storage means 13, the decoding control means 15 converts the compressed data transferred from the communication control means 16 into the stored and decoded data and stores it in the image information storage means 13. Transfer and store. By repeating this, the received data for one page is stored in the image information storage means 13.

[0018]

As described above, according to the present invention,
By setting the minimum transmission time of the DIS signal to be transmitted to the partner transmitter to 0 msec when the image information storage means receives it, the minimum transmission time in communication is set to the minimum transmission time of the partner transmitter. Since the minimum transmission time of the transmitter is shorter than the minimum transmission time of the receiver, the communication time can be shortened.

In the present invention, for example, when the recording capacity time of the receiver is 20 mSEC / line and the transmission capacity time of the transmitter is 10 mSEC / line, the minimum of the initial identification signal is received at the time of memory reception or memory proxy reception. To declare the transmission time as 0 mSEC / line, the transmitter sends the facsimile data at 10 mSEC / line. On the other hand, in the conventional receiver, the transmitter sends the facsimile data at 20 mSEC / line in order to declare the minimum transmission time of the initial identification signal to be 20 mSEC / line even when the memory reception or the memory substitution reception is performed. . According to the present invention, the amount of facsimile data sent from the transmitter at the time of memory reception or memory proxy reception can be reduced, so that the communication time can be shortened. In the personal class facsimile, since the recording capacity time tends to be larger than the transmission capacity time, the application of the present invention is particularly effective.
