ABSTRACT:
A data transfer method and apparatus for an image reading apparatus suitably used with an image scanner is improved in that a transfer line apparatus is simplified in construction and produced with a reduced cost by an improved transferring technique of data. The data transfer apparatus is incorporated in an image reading apparatus including first and second optical image reading units and comprises a storage section for storing data from a first operating one of the first and second optical image reading units from which paper image information is to be read out later, a first data transfer section for successively transferring, by way of a data transfer line, data from the first operating image reading unit, and a second data transfer section for successively transferring, after the data from the first operating image reading unit have been transferred by the first data transfer means, the data from the other later operating image reading unit stored in the storage means at a rate higher than the data transfer rate at which data are transferred by the first data transfer means by way of the data transfer line.
