A recording apparatus has a buffer for dividing a storage area into a plurality of areas in a scanning direction of a recording head to record data by allowing a carriage loaded with the recording head to scan data on a record medium, and storing the divided image data in a divided area unit, and includes: a write control unit for controlling write address information about image data in the area unit for data of each color for storage of the image data divided in an area unit in the buffer; a read control unit for controlling for data of each color read address information for a read of image data stored in the buffer; and a record data generation unit for generating record data in a unit of the divided area based on the read image data according to the read address information.

Term end not estimated
The present invention relates to a recording apparatus and a method for controlling the recording apparatus, or the like.
Relating to a printing apparatus, the conventional technology using a ring structure for a recording buffer is suggested in Japanese Patent Laid-Open No. 59-121432. The conventional technology is configured by an address pointer for storage of print data in a memory area, an address pointer for retrieval of data, and a print data count register for management of a blank area in the memory area with a view to efficiently using the memory of a cyclic area.
However, when a common ring buffer structure in the conventional technology is applied to a recording apparatus for full-color printing, it can be successfully applied to the recording head of one color, but there occurs the problem with the recording heads of other plural colors that data storage areas cannot be sufficiently reserved.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
FIG. 1 is a block diagram of the record control unit of a recording apparatus according to an embodiment of the present invention;
FIGS. 2A and 2B show the data structure when the data transferred from the host computer is stored in the reception buffer;
Preferred embodiments of the present invention will now be described in detail in accordance with the accompanying drawings.
Preferred embodiments of the present invention are described below in detail by referring to the attached drawings.
In the following embodiments, a printer is explained as a recording apparatus in the inkjet recording system.
