Abstract

PURPOSE:To automatically select vertical or lateral printing of input characters or image informations and to permit manual operation of the above selections also by controlling the recording directions corresponding to the directions or sizes to be used. CONSTITUTION:Supporting that Y is the paper feeding direction and X is the paper width direction, the dimension in X direction is detected by a detection resistance 2 and the dimension in Y direction is detected by a detection resis tance 5, and after analog-to-digital conversion, the results are stored in a micro computer of a controller 5 as digital data. In case of automatic mode by a microcomputer, the detected informations after analog-to-digital conversion are respectively input and the values are compared to calculate Y-X. By the decision of positive/negative calculation a vertical printing is selected if found to be positive and a lateral printing is selecting if found to be negative. If a manual operation is to be selected, an automatic key is not to be turned ON, and by the use of vertical or lateral selection key a desired printing mode is picked up.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for recording characters or images on a sheet.

Conventionally, this type of apparatus has adopted a method in which character processing is performed only in accordance with a unique method notified to the processing device in advance, and paper feeding is adjusted to the unique method. However, this method has the disadvantage that it cannot be recorded if the appropriate paper is not available.

The present invention eliminates the above-mentioned drawbacks, and the present invention automatically or manually determines whether input characters and image information are to be printed vertically or horizontally according to the direction of the sheet. This allows specification.

The present invention will be described in detail below with reference to the drawings.

FIG. 81 is a schematic block diagram showing the principle of the present invention, in which 1 is an input means for inputting character information through some input medium, 4 is a means for manually specifying vertical writing/horizontal writing regardless of paper feed size, 6 means for detecting the length/width (that is, the length and width) of the paper in the paper feed cassette;
5 is means for comparing the length/width detected by 6 and determining the paper orientation or size of the paper from the result to determine vertical/horizontal writing; 2 is according to the information input from 4 or 5; Character processing and page creation processing and means for storing the same; 3 represents means for outputting the stored information; the output means includes a character generator that converts character codes into character fonts, and a laser beam is output according to the output pixel data There is a laser beam printer that modulates the latent image to record pixels on a photoreceptor and develops it.

FIG. 2 shows the paper feed size detection means and structure. Reference numeral 11 can accommodate the largest paper that can be fed by the paper feed cassette device. Reference numerals 12 and 15 represent paper detection means, and a paper size detection sensor such as a sliding resistance is embedded along this groove in the paper feed cassette storage section of the main body, and the paper size can be detected at certain regular intervals. It looks like this. Reference numerals 13 and 16 are paper press plates whose sliding resistance can be changed by moving them. Reference numerals 14 and 17 represent paper holding plate guide grooves, which align the paper feed, prevent jams, double feeding, etc., and ensure smooth paper feeding.This device detects the orientation and size of the paper, and controls the controller 5. will be notified.

That is, Y is the paper feeding direction, X is the paper stack direction, the size in the X direction is detected by the detection resistor 2, and the size in the Y direction is detected by the detection resistor 5, and each is A/D converted and sent to the controller 5 as digital data. is taken into the microcontroller.

Figure 3 shows the processing flow in the case of automatic mode using a microcomputer, in which the A/D converted detection information is input in Step 1, 2) the values are compared and it is decided whether to print vertically or horizontally. Calculate y-x to determine (step 3), horizontal size (LH) and vertical size (L
Calculate (LV - LH) from V), and determine which direction is longer by determining whether it is positive or negative in step 4. If positive, vertical printing is specified, and if negative, horizontal printing is specified. still,
Positive includes the case where Y and X are equal. By the way, if the paper size is small, that is, if X is smaller than the minimum M, the print will be forcibly printed horizontally to make it easier to read. In the case of manual designation, the desired print mode is determined by not inputting the auto key but by inputting the vertical or horizontal designation key (step 7.8).

Figure 4 shows the printing method for vertical printing (baud rate).The horizontal direction is the cell width, and the vertical direction is the cell height, one character larger than the position (0, O) corresponding to the printable area. . ), the cell width moves in the +t One page force ≦ made.

For example, a laser beam is scanned by a polygon mirror over a photoreceptor in the X direction. The Y direction is scanned by rotating the photoreceptor. Therefore, the code memory and character generator are accessed in synchronization with each scan to output pixel data.

Figure 5 shows the printing method for horizontal printing (land, scape), where the lower left corner position corresponding to the printable area @ (O+ Y
From the position of ff1ax), the digit direction is set in the -Y direction and the row direction is set in the +X direction in accordance with the size of one character (cell), and one page is created. However, in horizontal printing, the characters are rotated 90 degrees to the left. This can be achieved by temporarily storing the pixel data in a memory, subjecting it to known rotation processing, and outputting it.
