ABSTRACT:
A copying machine comprises an imaging mechanism and a recording mechanism. An imaging sub-scan carriage of the imaging mechanism is scanned in the sub-scanning direction between an imaging start position and an intermediate position to image a master. The recording mechanism includes a recording medium such as a recording drum and a recording sub-scan carriage. The recording medium rotates in the main scanning direction while the recording sub-scan carriage scans in the sub-scanning direction perpendicular to the main scanning direction. When the imaging sub-scan carriage is scanning for one line, the recording sub-scan carriage is also scanning for one line, during which the recording medium performs one main scan so that a latent image of one line of the master can be formed on the recording medium. In response to the first sub-scan of the imaging sub-scan carriage between start and intermediate positions, the recording sub-scan carriage conducts the sub-scan between start and intermediate positions in relation to the recording medium. In response to the subsequent sub-scan of the imaging sub-scan carriage between start and intermediate positions, the recording sub-scan carriage conducts the sub-scan between intermediate and termination positions, so that a TWIN-COPY latent image of the master which is imaged by the imaging sub-scan carriage can be formed on the recording medium.
