Abstract
Abstract A facsimile apparatus includes a read unit which reads a document sheet image, and a memory which stores the read image data. A recorder records the image data on a record sheet, and a selection unit selects a first copy mode or a second copy mode. In the first copy mode, the image data read by the read means is stored in the memory, and after the completion of the storing of at least one page of image data, the image data read from the memory starts to be recorded by the recorder. In the second copy mode the image data read by the read unit starts to be recorded by the recorder before the completion of the reading of one page of a document sheet. A controller asynchronously conducts reading of the image data by the read unit and recording of the image data by the recorder when the select unit selects the first copy mode, and synchronously conducts the reading of the image data by the read unit and the recording of the recorder when the select unit selects the second copy mode.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
179 words
A image forming apparatus comprising: read means for reading a document sheet image at a predetermined reading period line by line; memory means for storing the image data read by said read means; record means for recording the image data on a record sheet at a predetermined recording period line by line; selection one of means for selecting a first copy mode in which the image data read by said read means is stored in said memory means, and after the storing of at least one page of image data, the image data read from said memory means starts to be recorded by said record means, and a second copy mode in which the image data read by said read means starts to be recorded by said record means before the completion of the reading of one page of document sheet; and means for asynchronizing the reading period and the recording period when said select means selects the first copy mode, and synchronizing the reading period and the recording period when said select means selects the second copy mode.
Claim 2
Dependent Claim
179 words
A image forming apparatus comprising: read means for reading a document sheet image at a predetermined reading period line by line; memory means for storing the image data read by said read means; record means for recording the image data on a record sheet at a predetermined recording period line by line; selection one of means for selecting a first copy mode in which the image data read by said read means is stored in said memory means, and after the storing of at least one page of image data, the image data read from said memory means starts to be recorded by said record means, and a second copy mode in which the image data read by said read means starts to be recorded by said record means before the completion of the reading of one page of document sheet; and means for asynchronizing the reading period and the recording period when said select means selects the first copy mode, and synchronizing the reading period and the recording period when said select means selects the second copy mode.
Claim 3
Dependent Claim
60 words
