Abstract: A method of searching a plural pre-registered data lines in which each of the data lines has data units such as letters and an index number, and of registering a new data line which also has data units among the data lines. The index number indicates the number of the coinciding letters from the first letter between each of the data lines and a data line one preceding to the data line. The method includes the step of comparing the new data line with the first ordered data line among the pre-registered data lines according to alphabetical order. If the new data line is not the same as the first ordered data line, other pre-registered data lines are searched in order to determine an order of the new data line to be registered among the pre-registered data lines.

Abstract: A facsimile apparatus is provided having a image reader for photoelectrically reading information on a document and a communication device for calling a recipient and for transmitting the read information through a communication line. There is further provided a memory for storing the information. In this configuration, when the communication line of the recipient is detected as being occupied, the communication device stores the read information into memory once, and when the communication line is connected with that of the recipient by redialing operation, the communication device transmits the stored information from the memory.
