摘要:
A communication device includes a storage medium for storing a program and information used to detect any error in the program, to prevent the communication device from further abnormal operation when an error occurs in the stored program. The occurrence of an error in the program is detected by performing a calculation based on the stored program, and comparing the result of the calculation with the above-described information stored in the storage medium. A predetermined operation is further performed depending on the result of the comparison.

In case of reading an original of plural pages and collectively transmitting the successive short length pages as one page, the number of transmitted pages recorded on a transmission record list becomes different from the number of read pages, so that it is difficult for a user to judge, from such list, whether all the pages have been transmitted. In case the number of actually transmitted pages is different from the number of read or received pages stored in the second RAM, the user can select in advance, by a key depression on a keyboard, whether to record both the number of actually transmitted pages and the number of read or received pages stored in the second RAM or to record either one of the numbers, as the number of pages to be recorded on the transmission result list. In case of storing image data of plural pages of original read by a contact sensor in an image memory and collectively transmitting the image data of successive plural pages, stored in the image memory, as one page, judging from the recordable number of lines at the receiving side, a CPU causes a display unit to display both the number of actually transmitted page number and the number of read page included in the transmitted pages.

When a plurality of pages of image data are combined into one page of image data for transmission, the direct combination of the image data having different resolutions and the resulting recording of the image data on one record sheet while the image is partially expanded or reduced are prevented. In combining two pages of image data into one page of image data for transmission within a range in which the number of read lines of read image data does not exceed the number of available lines for recording per page at a transmission destination terminal, if the read resolutions of both image data are equal, the two pages of image data are combined into one page of image data for transmission, and if the read resolutions are different, the combination is not conducted and the image data of the respective pages are transmitted as the independent pages of image data. A facsimile apparatus minimizes the possibility of transmission disable due to a full state of a memory when a plurality of pages of image data having short sub-scan lengths stored in the memory are transmitted. The image data acquired by reading a document sheet by a contact sensor 13 is compression-coded by an encoder 103 of a read/write codec device 10 and it is stored in an image memory 6. After a plurality of pages of image data having short sub-scan lengths have been stored in the image memory 6, the image data are combined into one page of image data on a communication protocol and it is transmitted to a transmission destination apparatus through a modem 17 and a network control unit 18. When it is detected that a remaining capacity of the image memory 6 is small, the combination transmission of the image data is canceled and the image data stored in the image memory 6 is immediately read and transmitted.
摘要:
A communication apparatus can transmit image data stored in a memory in a manner capable of reducing the running cost. The number of input lines for each page is recognized for image data of a plurality of pages input and stored in the memory. When transmitting the stored image data of the plurality of pages, the number of recordable lines per page of a recording sheet used in a communication partner's terminal is recognized, and image data for one page obtained by combining image data of a plurality of consecutive pages is transmitted. The reception side combines a maximum number of image data for a plurality of pages recordable on a single recording sheet, and transmits the obtained image data as image data for one page. Image data of different files for the same communication partner are also combined in the above-described manner.

A communication apparatus capable of transmitting image data in a form capable of reducing a running cost is provided. When a plurality of pages of image data to be transmitted can be recorded on one record sheet at a receiving station, a plurality of pages of image data are combined into one page of image data for transmission within a range in which the image data are recorded on one sheet at the receiving station and in such a manner that the plurality of pages of image data are recorded on the record sheet in vertically evenly divided areas. When a plurality of pages of image data to be transmitted can be recorded on one record sheet at the receiving station, main scan lengths of the plurality of pages of image data are made equal and the plurality of pages of image data are combined into one page of image data for transmission within a range in which the image data are recorded on one record sheet at the receiving station and in such a manner that the image data are recorded on the record sheet in evenly divided areas.
摘要:
A facsimile avoids waste of record sheets due to recording of image data only at the top of a record sheet with the bottom of the sheet being left blank. This is achieved by summing the number of lines on a plurality of document sheets, with the sum being compared with the sub-scan length of the record sheet, and if the sum can be accommodated by the record sheet, the image data of the plurality of document sheets are combined as one page of image data for transmission.
摘要:
In a data communication apparatus, when performing a calling operation, an image transmission speed is assigned using a CCITT nonstandard reception command NSS after transmitting a dial signal, and the NSS is repeatedly transmitted at a predetermined time interval. Upon reception of a reception-preparation-confirming signal transmitted from an apparatus of a communication partner, a command, an identification signal and image data are transmitted at the image transmission speed based on information relating to the communication partner's apparatus which has been stored, so that the time required for communication procedures is shortened.
摘要:
A facsimile apparatus and a facsimile communication method prevent the termination of communication in error due to memory capacity shortage when confidential communication or relay designation communication is effected by using a sub-address additionally recommended by the CCITT/T.30. When a remaining capacity of an image memory is smaller than a preset threshold, sub-address control information representing the invalidity of the sub-address is stored in sub-address control memory means. As a result, when an initial identification signal or a send command signal is sent to a destination station, a bit indicating that the sub-address is valid is sent without being set. Namely, the invalidity of the sub-address function is informed to the destination station. Thus, the confidential reception or the relay designation reception using the sub-address is not accepted and the termination of the communication in error due to the memory capacity shortage is avoided.

A facsimile apparatus using a selective polling signal includes a holding unit for holding a polling image, a receiving unit for receiving the selective polling signal, an extraction unit for extracting a process command for the image held in the holding unit from the selective polling signal received by the receiving unit, and an execution unit for executing the process command extracted by the extraction unit.
摘要:
There is described a facsimile device which includes a first transmitting device that transmits previously stored communication information of a receiving device to the receiving device; and, in response to such transmission, the receiving device compares that communication information with its own communication information. When the comparison shows a difference, a second transmitting device, which is associated with the receiving device, transmits new communication information back to the first transmitting device; and, in response to this, the first transmitting device updates the stored communication information.
