Abstract

PURPOSE:To avoid the omission of picture information to a destination facsimile receiver by applying split transmission with a shorter length than a maximum recording length informed on a communication protocol when each prescribed selection signal at a district using a cut paper size and the relevant part of a call selection signal are coincident with each other. CONSTITUTION:A system control section 10 stores a prescribed selection signal of a district using cut paper to a storage section 21 by the instruction of an operator. A 2nd comparator 22 compares a prescribed selection signal stored in the storage section 21 with a part corresponding to an output of a dial input section 61 and stores information representing the cut paper size of a destination facsimile receiver to a register 52 as the information representing an original length based on the result of coincidence. Then a 1st comparator 53 compares the content of the register 52 with the output of a counting means 51 and the system control section 10 controls a picture information transmission means and a scanning means based on the result of coincidence of the comparator 53 to apply split transmission of the picture information with a shorter length than the maximum recording length. Thus, the omission of information to the destination facsimile receiver is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is applied to a facsimile transmission device for image communication.

〔overview〕

The present invention provides a facsimile transmitter that, when a predetermined selection signal for an area where a preset cut paper size is used and a corresponding portion of a call selection signal match, a notification is sent in a communication procedure. This method prevents image information from being lost to the recipient's facsimile receiver by dividing and transmitting the image at a value shorter than the maximum recording length.

[Conventional technology]

Conventionally, facsimile transmitters have been able to transmit A4 recording paper to facsimile receivers according to communication procedures based on CCITT (International Telegraph and Telephone Consultative Committee) T.30.
Even if a cut paper size recording paper that is shorter vertically than A4 recording paper is set, it is notified as A4 size, so if the facsimile receiver is set with recording paper that is shorter vertically than A4 recording paper. In response, I sent an A4-sized manuscript.

On the other hand, roll paper has been used as recording paper in conventional facsimile receivers. Therefore, even if the original to be sent is longer in the sub-scanning direction than the standard size, if the sending side divides the original and sends it in accordance with the standard recording paper size notified by the receiving side during the communication procedure, the receiving side will be able to correctly display the image information. It is possible to record without any omissions.

However, recently, an increasing number of facsimile receivers are using standard cut paper for storage and handling advantages. In particular, in North America, a so-called letter-size recording paper is used, which is about 2 cm shorter in the vertical direction and about 0.6 cm longer in the horizontal direction than A4-size recording paper.

[Problem that the invention seeks to solve]

In conventional facsimile receivers such as those mentioned above, CCIT
According to the communication procedure based on T.30, even if A4 or letter size paper is set in the facsimile receiver, it will be reported as A4 size, so letter size paper will be sent as cents. If an A4-width document is divided into A4-length documents and sent to a facsimile receiver, image information in the middle of the document may be lost.

Further, on the receiving side, there is a similar drawback when using form recording which is slightly shorter in the sub-scanning direction than B4 size.

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, it is an object of the present invention to provide a facsimile transmitter that does not cause loss of image information to a facsimile receiver at the destination.

[Means for solving problems]

The present invention includes a dial input unit that outputs a selection signal for exchange connection by operation, and an image information transmitting unit that inputs the maximum recording length notified in the communication procedure from the destination facsimile receiver and transmits image information. , a scanning means for scanning a document and providing image information to the image information transmitting means; a counter for counting information indicating the length of the fed document; a register for storing information indicating the length of the document in the sub-scanning direction; a first comparator that compares the contents of the register and the output of the counter;
A means for storing information indicating the maximum recording length as information indicating the document length, and controlling the scanning means and the image information transmitting means based on the matching result of the first comparator to control the document indicated by the contents of the register. A facsimile transmitter comprising: a system control section for transmitting image information in a length; a second comparator for comparing the selection signal with a corresponding portion of the output of the dial input section, the system control section storing the predetermined selection signal according to an instruction from an operator; The present invention is characterized in that it includes means for storing information indicating the cut paper size of the destination facsimile receiver as information indicating the document length based on the matching result of the second comparator.

[Effect]

The system control unit records a predetermined selection signal for the area where cut paper is used according to the operator's instructions.1. ! Store it in the section. The second comparator compares a predetermined selection signal stored in the storage section with a corresponding portion of the output of the dial input section. Based on the matching result of the second comparator, information indicating the cut paper size of the destination facsimile receiver is stored in a register as information indicating the document length. Through the above operations, the first comparator compares the contents of this register with the output of the counting means, and the system control section controls the scanning means and the image information transmitting means based on the matching result of the second comparator. Since the image information is divided and transmitted at a value shorter than the maximum recording length, it is possible to prevent information from being lost to the destination facsimile receiver.

Here, the features of the present invention include a storage section 21 that stores a predetermined selection signal for the area where the cut paper size is used, and a dial input section 61 that stores the predetermined selection signal stored in the storage section 21 and a dial input section 61. The system control unit 10 includes a comparator 22 as a second comparator for comparing the output of the comparator 22 with a corresponding portion of the output of the comparator 22. The present invention further includes means for storing information indicating the cut paper size of the destination facsimile receiver as information indicating the document length based on the matching result.

The operation of the facsimile transmitter having such a configuration will be explained. The table shows the contents of the registers of the facsimile transmitter of the present invention.

In the figure, the operator first uses the dial input section 61 to register a selection number for dividing shorter than the normal division length.
This is performed via the system control unit 10, which includes a PU, ROM, RAM, input/output circuits, and the like. for example,
When making a call from Japan to North America, you dial "0011" and then dial the area code and local number of the other party's facsimile receiver, so the selection number is "0011".
011" is registered.

The operator dials the dial input section 6 into the facsimile receiver.
When the selection number of the other party is input from 1, it is input to the automatic dialing circuit 62, converted to a dial signal, and sent to the telephone line 80 via the network control section 70. At the same time, the selection number of the other party is compared by the comparator 22 with the selection number registered in the storage section 21 by the system control section 10 . The comparison results are input to the system control unit 10. If the comparison results do not match, the system control unit 10 sets in the register 52 the number of pulses corresponding to the value of the recording paper size in the sub-scanning direction notified by the other party's facsimile machine according to the communication procedure.

The original 41 is fed by a feed motor 42 driven by a pulse generator 4G and a motor controller 47, and after passing above an original detection sensor 45, is converted into image information by a lens 43 and a photoelectric conversion element 44. Furthermore, the video section 31, encoding section 32, and communication control section 33 controlled by the system control section 10 transmit the signal to the telephone line 80 via the network control section 70.

The system control unit 10 clears the counter 51 when the leading edge of the document 4I passes over the document detection sensor 45. The comparator 53 sequentially compares the contents of the register 52 and the output of the counter 51 as input, and when the contents of the register 52 and the output of the counter 51 match, the output of the comparator 53 turns "on" and the system control section Notify 10.

When feeding a document, the system control unit 10 always uses the document detection sensor 45 to alternately check the presence or absence of the document and the output of the comparator 53. If the output of the comparator 53 is "ON", page division processing is performed. If the output of the comparator 53 is "OFF" and there is no document (when there is no document on the document detection sensor 45), the system control Section 10 does not perform page division.

Therefore, if the preset selection number and the calling selection number are different, the long document is divided according to the value of the recording paper size in the sub-scanning direction notified in the communication procedure.

On the other hand, if the selection number registered in the storage unit 21 and the selection number of the destination party match, the corresponding number of pulses shown in the table is added to the recording paper size of the destination facsimile receiver notified in the communication procedure. cent.

Table [Effects of the Invention] As explained above, the present invention has the excellent effect of being able to transmit image information to the destination facsimile receiver without causing any loss of image information.
