Description

Description: TECHNICAL FIELD The present invention relates to an information processing apparatus. [Prior Art] As an image information processing apparatus, for example, in a thermal transfer printing apparatus having a display device, a printing font and a display font are different from each other with respect to character fonts. It has memory and memory for display fonts. [Problems to be Solved by the Invention] Therefore, the number of memories used in the printing apparatus described above increases. Also, for characters with different typefaces,
There was no distinction in display fonts. This is because the use of the print font memory and the display font memory for each typeface increases the number of memories (or runs out of memory). Further, since fonts are distinguished between those for printing and those for display, it is not possible to know which font the printing font is from the displayed characters. Therefore, an object of the present invention is to create a pattern of an appropriate size to be displayed on a display device from a font pattern for printing so that a character pattern on a display screen of the display device can be printed as it is. Another object of the present invention is to provide an information processing apparatus which can eliminate the difference between displayed characters and printed characters by displaying the displayed characters. [Means for Solving the Problems] In order to achieve the above object, the present invention provides a keyboard for inputting character code information and print instruction information, and storage means for storing a pattern corresponding to the character code information. Determining means for determining whether or not the character code information has been input from the keyboard; and when the determination means determines that the character code information has been input,
Generating means for generating a first character pattern and a smaller second character pattern obtained by compressing the first character pattern from the pattern stored in the storage means; and generating the first character pattern by the generating means for printing. A first random access memory for storing the obtained first character pattern;
A second random access memory for storing a second character pattern generated by the generating means for displaying, and a print instruction information from the input means,
Print control means for printing a first character pattern stored in the first random access memory. [Operation] According to the present invention, a pattern having a size suitable for display on a display device is created from a font pattern for printing and displayed, so that there is no difference between displayed characters and printed characters. . FIG. 1 is a block diagram of a character processing apparatus to which the present invention is applied. In FIG. 1, reference numeral 1 denotes a keyboard, which outputs a character (character) code information signal or a control code information signal in response to a key input. 2 is a ROM,
It has a storage area for a control program according to the flowchart of FIG. 6, a control program for the entire character processing apparatus, a character font for printing, and the like. Reference numeral 3 denotes a RAM, which has a storage area for printing character fonts and a storage area for display character fonts. Reference numeral 4 denotes a thermal transfer type printer unit, 5 denotes a central processing unit (CPU), and 6 denotes a display unit such as an LCD. FIG. 2 shows a keyboard and a display. In FIG. 2, K1 is a character (alphabet, number, etc.)
The key, K2 is various control keys, and K21 is a return key among the control keys. FIG. 3 shows an example of the mechanical structure of the printer unit, where 31 is a print head, and 32 is a head 31.
, A motor 33 for moving the carrier 32, and a platen 34 for feeding printing paper. An example of a display operation after a key input is shown with reference to FIG. In step S1, the CPU 5 determines whether the information input from the keyboard 1 is character code information. If it is character code information, in step S2, font information corresponding to the character code information is extracted from ROM2, stored in the print character font storage area of RAM3, and converted into the display character font storage area as follows. Process and store. That is, for example, FIG. 4 shows a print font of the character “A” composed of 24 × 24 dots, and FIG. 5 shows a display font of the character “A” composed of 12 × 12 dots. CP
U5 is 2 × as shown by g, g + 1,... In FIG.
The information of two dots (four dots) is stored in the display character font storage area in the RAM 3 in correspondence with the information of one dot as indicated by g and g + 1 in FIG. If there are three or more black portions in the unit of 2 × 2 dots (g, g + 1,...) In the print character font, one dot of the corresponding display character font is black. Next, in step S3, the character font stored in the display character font storage area of the RAM 3 is displayed on the display, and the process returns to step S1. If the information input from the keyboard 1 is not character code information in step S1, the process proceeds to step S4, where processing corresponding to the input code information is performed. For example, in the case of a return key code, the printer returns the carrier 32 of the printer 4, sends the character font in the print character font storage area of the RAM 3 to the printer unit 4, and prints the character font on paper. [Effects of the Invention] As described above, according to the present invention, a document created while looking at the display screen of the display device can be printed in a pattern as viewed on the display screen.
