Description

TECHNICAL FIELD The present invention relates to a communication device for transmitting different originals to different destinations by a single operation.

(Prior Art) Conventionally, when transmitting different originals to different destinations, the operator first sets the first original on the original table and transmits it to the first destination. Subsequently, the second original is set and transmitted to the second destination, which requires a plurality of operations.

(Problems to be Solved by the Invention) It is an object of the present invention to provide a communication device capable of transmitting different originals to different destinations by a single operation without performing such a plurality of operations. It is what

(Means for Solving the Problem) In order to achieve the above object, the present invention includes a black pixel number detection unit for detecting the number of black pixels of received recording image information, and according to the detected number of black pixels. In a facsimile apparatus that performs recording control, a reading unit that reads original image information of an original and original image information of the original read by the reading unit are sent to the black pixel number detecting unit, and the original is detected based on the detection result. Judgment means for deciding whether or not it is a blank original, and control means for recognizing the original decided to be a blank original by the judging means as a separation original and transmitting the transmission originals after the separation original to another destination. And the configuration.

(Operation) According to the above configuration, when originally recording received image information,
A black pixel number detecting means for detecting the number of black pixels from the received image information to be recorded and using the detection result for recording control is used for detecting the section original. Moreover, since a blank sheet is used as the separating document, it is not necessary to prepare a special separating document.

When a separated original is detected, subsequent originals are sent to different destinations that have been input in advance, so that the operator need only operate the first set, and the machine will automatically send the rest.

(Example) Hereinafter, an example will be described in detail with reference to the drawings. FIG. 1 shows the configuration of an embodiment of the present invention, in which 1 is a reading device, 2 is a black pixel number detector, and 3 is a recording device, and the black pixel number detector 2 is included in this recording device 3. Has been. Reference numeral 4 denotes a facsimile control device, which is composed of a terminal control device 5, a code decoder 6, and a communication control unit 7. Reference numeral 8 is a line interface.

At the time of transmission, the document image information a read by the reading device 1 is encoded by the encoder / decoder 6 and transmitted via the communication controller 7 and the line interface 8.

At the time of reception, the transmitted image information is decoded by the code decoder 6 via the line interface 8 and the communication controller 7, and the recorded image information b is recorded by the recording device 3.

The black pixel number detector 2 provided in the recording device 3 detects the number of black pixels from the recorded image information b.

Now, when sending different originals to different destinations, enter the page number to distinguish the originals for each destination, and separate originals (blank page)
To use. If the two do not match, it is detected as anomaly.
Terminate communication.

The following is an explanation of the operation in the case where transmission is performed sequentially with the transmission original, the separated original, and the transmission original set in that order.

First, when the first transmitted document is read and transmitted,
The terminal control device 5 detects the preset page number input "1", instructs the recording device 3 to detect whether or not the next page is a blank sheet, and sets the read original image information a as recorded image information b. Send to the recording device 3.

Further, since this page should be a separated document, it is not transmitted, and the recording device 3 informs the terminal control device 5 whether or not the separated document is blank at the end of reading the separated document.

If the result is blank, the terminal control device 5 transmits the next transmission original to another destination, and if it is not blank, the communication is terminated because of an abnormality.

FIG. 2 shows an embodiment of a black pixel number detector, in which 10 is a black pixel detection gate, 11 is a counter, 12 is a CPU, and 13 is a recording head.

The facsimile controller 4 sends the recording image information b and the transmission clock c to the recording head 13 and the black pixel detection gate 10.

The number of black pixels is counted by the counter 11, which the CPU 12 reads, stores and calculates.

At the time of reception, the above result is used for recording control, the head 13 performs recording scanning, and at the time of detecting a blank sheet, recording scanning is not performed and the detection result is returned to the facsimile controller 4.

FIG. 3 is a diagram showing the effective area of the original, where A is the effective area and B is the peripheral area of the original.

Since the reading unit easily reads black around the document, the CPU does not count the document peripheral area B in the recorded image information b when detecting a blank sheet, and determines that the blank area is a blank sheet when the number of blacks in the effective area A is less than or equal to a predetermined amount. To do.

(Effects of the Invention) As described above, according to the present invention, a single operation
Different originals can be sequentially sent to different destinations, which can reduce the work of the operator and save time.
The black pixel number detecting means originally detects the number of black pixels from the received image information to be recorded and uses the detection result for recording control, and since it is used for detecting a section original, a separate section original is used. It is not necessary to provide a detection device, and the hardware configuration of the device is the same as the conventional one, and it is possible to reliably detect a delimited original document. Furthermore, since a blank sheet is used as the separating original, it is not necessary to prepare a specially processed separating original, and it can be reused as an original sheet, which is a great effect.
