A force release mechanism releases the pedal plate from an urging force applied by the urging mechanism.

Abstract: Band rendering processing time in the case where the raster scanning direction of inputted output information and that of a print mechanism are different can be remarkably reduced, and rendering processing efficiency of each page is improved. To expect the further improvement of throughput, a display list to render objects into a band memory is formed on the basis of the inputted output information. A bit map image is rendered into the band memory in accordance with the display list. If it is determined that the raster scanning direction of the inputted output information and that of the print mechanism are different, a rotating process is executed to the bit map image rendered in a rendering step so as to be matched with the raster scanning direction of the print mechanism and the rotated data is transferred to the print mechanism.

Abstract: If Y, M, C, and K color component images are serially generated by one color component image generating device in four steps, it takes much time to perform image processing for printing a one-page full-color image. This makes it impossible to increase the printing speed. In addition, since conversion to Y, M, C, and K data is performed before rendering, rendering logic cannot be faithfully implemented, resulting in poor color reproducibility. In order to solve these problems, image generating devices (103–105) respectively render R, G, and B color component images in bitmap memories 106 to 108, which are divided into areas in units of predetermined bands obtained by dividing a page, on the basis of a display list which is common to R, G, and B data and stored in a memory (102). The rendered color component images on a band basis are converted into C, M, Y, and K color component images by a color space converter (109) in synchronism with the operation of a printer engine.

Abstract: An image processing apparatus which is set to receive data in the RGB format cannot directly receive image data in the YMCK format although a print process is finally done in the YMCK format. In this embodiment, when RGB data is input from a host computer, renderers respectively render the R, G, and B data, the rendered R, G, and B data are converted into YMCK data by a color space converter, and the YMCK data is output to an engine. On the other hand, when YMCK data is input, renderers respectively render Y, M, C, and K image data, and directly output them to the engine.

Abstract: A memory control apparatus which can effect memory high speed when performing a burst access from a CPU or the like to a memory is provided. When the access from the CPU is started, lower digits of the first address of the burst access are set into a counter. The CPU updates the data at a reading timing. By using the counter, the memory executes the access and the data obtained is stored into a latch. With this method, the data is read out from the memory earlier than conventionally, access can be executed at a high speed.

An image memory stores the image data generated by the image generation unit, and a data transfer unit transfers the record data from the image memory to a recording mechanism in synchronism with an operation of the recording mechanism.

Abstract: An image output apparatus generates image data in band units, and performs image-data generation and image-data output alternately using two band memories. Prior to image-data output, image data is preparatorily generated by each band, and it is determined whether or not there is a band requiring time for image-data generation longer than time for image-data output for one band. Regarding this band, the preparatorily-generated image data is stored. Upon printing, regarding a band, of which it has been determined that image data can be generated in realtime, image is generated in parallel to image output from its previous band, while regarding a band, of which it has been determined that image data cannot be generated in realtime, the stored image data is outputted after the completion of image output from its previous band.

Abstract: An image generation method and an image generation apparatus can execute conversion from edge addresses into dot patterns at a high speed and a low cost. A comparator compares predetermined upper-digit bits of input edge-address information indicating the position of a word of a dot pattern to be output with the value of a word counter for counting the number of words of dot patterns which have been output, and determines if an edge position indicated by the input edge-address information is present within the word currently being processed. A decoder detects the edge position within the word based on predetermined lower-digit bits of the input edge-address information. The detected edge position within the word is held within a flip-flop circuit.
