Abstract

PURPOSE:To transmit only specified facsimile(FAX) information to a high-order device side. CONSTITUTION:The high-order device registers prescribed communication control information in an image information storing part 15 through a high-order interface part 12. In the case of executing the communication of image information by a FAX equipment, communication control information sent at this time is compared with the registered communication control information, and when there is no coincidence, a line is disconnected without transmitting the image information. When both communication control information coincide with each other, the image information is stored in the storage part 15 and informed to the high-order device side. Consequently the high-order device can obtain only necessary image information.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile control device for connecting a facsimile device and a host device such as a computer, and more particularly to transmitting facsimile image information to the host device and sending image information from the host device. The present invention relates to a facsimile control device having a receiving function.

[0002]

2. Description of the Related Art Facsimile control devices for connecting a facsimile device and a host device such as a computer have been
The communication control means for controlling the communication of the facsimile and the storage means for storing the image information of the facsimile are provided. Then, when the image information is transmitted from the facsimile device, all of these facts are notified to the host device side. The upper-level device has come to pick up the image information that has received these notifications at a predetermined timing.

[0003]

As a result, in the conventional facsimile control apparatus, even the facsimile information that cannot be processed by the host apparatus is transmitted to the host apparatus. The upper-level device has unconditionally received such facsimile information. For this reason, for example, there occurs a problem that a higher-level device that performs processing by OCR receives image information that cannot be read by OCR, which causes a failure.

Further, in the conventional facsimile control device,
Even when the image information of a facsimile original that could not be processed by the host device was returned to the other party, there was a certain amount of time delay, so the result that the facsimile device could not process immediately appears. There was a problem that I did not understand and overlooked that the upper device side became incapable of processing.

Further, there is also a problem in that, when a communication error occurs at the time of reception, the host device cannot determine where the facsimile information is sent from. There is a case where a communication failure occurs when the upper device side returns the unprocessable result, and in this case, there is a problem in that it is not possible to notify the other party of the unprocessable result.

Therefore, an object of the present invention is to provide a facsimile control device in which only specified facsimile information is transmitted to a host device side.

[0007]

According to a first aspect of the present invention, there is provided a first receiving means which is connected to a facsimile device and receives communication control information and image information sent from these facsimile devices. Second receiving means connected to the device and receiving communication control information regarding the facsimile device which permits reception of image information from the host device; and communication control for storing the communication control information received by the second receiving device. For the information storage memory, the comparison means for comparing the communication control information sent from the facsimile device with the communication control information stored in the communication control information storage memory, and for the facsimile device for which no match is detected by the comparison means. In addition, the facsimile control device is provided with image information transmission control means for rejecting transmission of image information.

That is, according to the first aspect of the present invention, the communication control information of the facsimile machine, which the upper device side permits to receive the image information, is stored in the communication control information storage memory of the facsimile control device side, and the facsimile is stored. When the communication control information is transmitted from the device, it is compared with the communication control information stored in the communication control information storage memory by the comparing means, and when no match is detected, the transmission of the image information from the facsimile device is rejected. In this way, only the facsimile information that can be specified in advance can be transmitted to the host device side.

EXAMPLES The present invention will be described in detail below with reference to examples.

FIG. 1 shows the outline of the configuration of a facsimile control apparatus according to an embodiment of the present invention. The facsimile control device 11 includes an upper interface unit 12 connected to the upper device side, and a facsimile communication control unit 13 connected to each facsimile device. A storage control unit 14 that controls storage of image information and communication control information is provided between the upper interface unit 12 and the facsimile communication control unit 13. Storage controller 14
Is connected to an image information storage unit 15 for storing image information.

The facsimile control device 11 has a CPU (central processing unit) (not shown) for its control. The CPU also stores a control program in a storage medium such as a ROM (read only memory) (not shown), and a RAM (random
The access memory) is used as a working memory to perform control as described below. In addition,
When the image information storage unit 15 is composed of, for example, a magnetic disk, the storage of image information and the storage of programs can be shared.

FIG. 2 shows the flow of work in which the facsimile control device stores communication control information. Figure 1
The higher-level interface unit 12 of the facsimile control apparatus shown by is waiting for the communication control information to arrive from the higher-level apparatus (step S101). When the communication control information arrives (Y), the communication control information is stored in a predetermined area of the image information storage unit 15. At this time, if the communication control information has already been written, the content is updated (step S102).

FIG. 3 shows a control state when image information is sent from the facsimile apparatus to the facsimile control apparatus through a line. The facsimile communication control unit 13 shown in FIG. 1 waits for arrival of a facsimile signal including control information and the like from any of the facsimile devices (step S201). When the reception of the facsimile signal is started (Y), when it is confirmed that the communication control information is present therein (step S202), this communication control information and the communication control designated by the host device side described in FIG. A comparison operation is performed to determine whether the pieces of information match (step S203).

If the two pieces of communication control information match each other (Y), reception of image information from the facsimile device is started (step S204). The reception of the image information continues until the communication with the facsimile device is completed (step S205; N), and the received image information is stored in the image information storage unit 15.
Accumulated in. When the communication ends (step S205;
Y), the line is disconnected (step S206). After this, the fact that the image information has been received is determined by the upper interface unit 12
The higher-level device is notified via (step S207).
Based on this notification, the host device reads out the image signal stored in the image information storage unit 15 at a predetermined timing.

On the other hand, if both communication control information do not match in step S203 (N), it means that a facsimile signal is sent from a facsimile device which is not assumed by the host device. Therefore, in this case, a forced termination signal for forcibly ending the transmission of the signal is transmitted to the facsimile device (step S208). Then, the communication is terminated and the line is disconnected (step S20).
9).

In the facsimile control apparatus of the embodiment described above, the image information accumulated in the image information accumulating section 15 is notified to the upper apparatus, and thereafter, the upper apparatus takes the initiative to transfer the image information. However, depending on the system configuration, the facsimile control device may take the initiative and transmit the image information to the higher-level device side without giving notification.

[0017]

As described above, the facsimile control apparatus of the present invention rejects the transmission of image information from the facsimile apparatus to the facsimile control apparatus unless the communication control information matches. For this reason, when the facsimile document is transmitted, the transmission error can be immediately noticed by rejecting the transmission, and the host device side returns the same image information as the facsimile document to the facsimile device side. There is no need for such trouble. Further, since the facsimile apparatus side can immediately know that the processing is impossible, there is an effect that the fact that the processing cannot be performed is not overlooked.
