DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus and, more particularly, to a facsimile apparatus which performs a calling operation while storing read information in a memory.

[0002]

2. Description of the Related Art Conventionally, a facsimile apparatus which performs a calling operation while storing read information in a memory has performed a calling operation after a predetermined time has elapsed from the start of storing in a memory. Here, the predetermined time is always constant, and, for example, the calling operation is performed immediately after the storage in the memory is started.

[0003]

However, in the above-mentioned conventional example (for example, a calling operation is performed immediately after storage in the memory is started), for example, the reading speed is relatively slow, and the transmitting speed is relatively low. When the capability (decoding / recording) is fast, when the information of a simple pattern is transmitted, the system is limited by the reading speed of the transmitter. For this reason, there is a major drawback in that the line is captured for a much longer time than when a call is made after the storage in the memory is completed.

In addition, regardless of the image information reading mode (halftone, binary), the encoding amount of the image information, the number of change points of the black information and the white information of the image information, and the number of set transmission originals, The time from the start of storage to the time when a call is made is kept constant. For this reason, there is a drawback that the line is captured for a longer time than in the case of the memory transmission (after the storage in the memory is completed, a call is made and the information stored in the memory is transmitted).

[0005]

According to the present invention, a call is made to a communication partner after a lapse of a predetermined time from the start of reading of transmission information and storage in a memory, and the transmission information is read. In a facsimile apparatus for sequentially transmitting information stored in a memory, the facsimile apparatus has means for storing the capability of the communication partner, and starts storing the transmission information in the memory according to the capability of the communication partner, Change the time to call. For example, the capability of the receiver for the minimum transmission time is stored, and based on this information, the time from when the transmission information is stored in the memory to when the call is made is changed. The shorter the minimum transmission time on the receiver side, the longer the time from the start of storing the transmission information in the memory until the call is made.

According to the present invention, transmission information is read,
After a lapse of a predetermined time from the start of storage in the memory, the facsimile apparatus which calls the communication partner and sequentially transmits the information stored in the memory while reading the transmission information. Thus, the time from the start of storing the transmission information in the memory to the time of calling is changed. For example, the time from when the transmission information is started to be stored in the memory until the call is made is changed based on the reading mode (binary, halftone) on the transmitter side. When the reading mode on the transmitter side is the halftone, the time from the start of storing the transmission information in the memory until the call is made is shorter than in the binary mode.

In the above, there is provided means for reading the transmission information and detecting the number of transition points between the black information and the white information, and starting storing the transmission information in the memory based on the number of transition points. Change the time before calling. When the number of change points of the black information and the white information is large, the time from the start of storing in the memory to the calling is shortened.

In the above, there is provided means for reading the transmission information and detecting an encoding amount for the predetermined line information,
Based on this coding amount, the time from the start of storing the transmission information in the memory to the time of calling is changed. When the coding amount for the predetermined line information is equal to or more than the predetermined amount, the time from the start of storing in the memory to the time of calling is shortened.

The facsimile apparatus has means for checking the number of originals set in the facsimile apparatus.
The time from the start of storing in the memory to the calling is changed depending on the number of set originals. The longer the number of set originals, the longer the time from the start of storage in the memory until the call is made.

The calling timing in the facsimile apparatus described above is defined as a page being read and a page break.

[0011] Thus, compared with the memory transmission (after the storage in the memory is completed, the call is made and the image information is transmitted) in the facsimile apparatus which performs the call and transmits during the storage in the memory after the storage in the memory is started. It has become possible to provide an efficient facsimile machine that does not seize the line for a much longer time.
