Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document information processing device, and particularly to a document information processing device that creates various characters by modifying and editing character fonts, for example.

[Conventional technology]

In recent years, document information processing devices, such as word processors, have rapidly become more multifunctional and lower in price, and devices that were previously used only by professional operators to create office documents are now being used in offices. Nowadays, all people in Japan are now able to easily input documents using keyboard operations instead of writing them with a pencil.

Such devices have various types of characters and store font information for each character in memory.

For example, ■, ■・・・・・・■, [stock]
, O, ■, ■, etc. There are characters surrounded by circles, and font information independent of the enclosed characters is stored in the memory. Some devices also have a function to create enlarged characters, such as quadruple characters, horizontal double characters, vertical double characters, etc., using stored fonts.

[Problem that the invention is trying to solve] However,
In the above-mentioned conventional example, in order to achieve low prices, there was a limit to the memory capacity, and therefore there was a limit to the number of encircled characters that could be registered.

In addition, there is a method that makes it possible to create round characters for all fonts stored in memory by compressing the font information stored in memory and overlaying round character fonts in the empty area. Although it has been proposed,
When you execute enlarged round characters created using this method, such as double-width, double-height, and quadruple characters, the font stored in memory is first reduced and then enlarged, so the font of the enlarged character changes from the original. The shape will be distorted compared to the font.

[Means for solving the problem (and operation)] According to the present invention, means for enlarging and reducing an existing normal character font are provided, and some character units of the enlarged font are reduced. By overlaying a specified pattern according to the enlarged pattern information on the reduced font, it is possible to print beautiful enlarged round characters.

The present invention has been made in view of the above drawbacks, and an object of the present invention is to provide the user with free document expression by increasing the number of circled characters without increasing the memory; To simultaneously make it possible to create beautiful fonts by enlarging and printing round characters by a simple means.

〔Example〕

FIG. 2 is a block circuit diagram of a document information processing apparatus according to an embodiment of the present invention. In the figure, l is the keyboard section (KB), character keys for inputting characters, conversion keys for kanji conversion, edit keys for editing documents, cursor keys, print key PK for printing control, rotation printing, etc. Print format key PSK that specifies the print format and first page number,
Formatting key SS that specifies the number of digits in the document format
K etc. are arranged. Upon receiving a key scanning signal from the KBI, a key signal corresponding to the pressed key is sent to the keyboard controller (KBC) 2. Display section 3
is composed of, for example, an LCD (liquid crystal display panel), and displays a part of a document that is being created or has been created, a message, etc. The display unit 3 has a dot matrix configuration and is controlled by a display controller (LCDCONT).

, segment driver 5EGD6.

DSPRAM7 is display RAM (Random Ac
cess Memory) is where display information such as letters, numbers, symbols, etc. displayed on the display unit is stored.

Printer 8 is a thermal transfer printer with a 32-dot thermal head TH, carrier motor CM, and feed motor F.
The carrier has a group of thermal heads arranged in a vertical line, and the thermal head drive signal from the printer controller (PCONT) 9 is sent to the head driver ( The ink on the transfer tape facing the thermal head is applied onto the opposing paper surface, and dots of characters to be printed are printed. Carrier motor driver (
CMD) 11 moves the position of the carrier to the next dot position by exciting and rotating each phase of the pulse motor in response to an excitation signal sent from the printer controller PCONT9.

The feed motor driver (FMD) 12 feeds the paper to be printed by driving the feed motor (FM) according to the feed motor drive signal sent from the printer controller PCONT9, and moves the thermal head to the printing position of the next line. let The two-piece down motor driver (MD) 13 is the printer controller P CONT.
The polarity of the voltage applied to both ends of the up-down motor M is reversed in response to an up signal or a down signal from 9. This changes the rotation direction of the up-down motor,
Bring the thermal head on the carrier into contact with or away from the paper surface. The HP detects the position of the moving carrier with a position detection switch, and always determines the state of this switch when resetting and when power is restored (turning on from the sleeve state).
Check the carrier's home position. Further, if the position of the carrier is shifted due to a signal or a paper jam, correction is made according to the state of the position detection switch HP.

The RAM 14 is a readable and writable random access memory, and stores the compressed font information stored in the ROM 5 into font buffers FNTBF and 4BFNTB.
