Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a character information generating device.

[Prior Art] Conventional character information generation devices using vector information are effective in generating character information of any size, but vector information is converted into dot information each time a request for character generation is made. Ta.

[Problem to be Solved by the Invention 1] In the conventional example described above, vector information is converted into dot information each time the same character appears, which has the drawback of taking a very long time.

[Means for Solving the Problems] The present invention provides a character conversion means that stores a plurality of pieces of character information as vector information, a storage means that stores character dot information converted by the character conversion means, and a memory. A management means for managing the character dot information stored in the means, and if the generation requested character information is managed by the management means at the time of a character generation request, the corresponding character dot information is generated from the storage means and the information is not managed by the management means. If not, the present invention is characterized by comprising means for generating corresponding character dot information by the character generating means.

[Function] According to the present invention, characters once converted from vector information to dot information are stored in the storage means as dot information, and from the second time onwards, character conversion is performed at high speed by using the dot information.

[Embodiment] FIG. 1 is a block diagram showing one embodiment of the present invention. 1
2 is a CPU that controls a series of processing based on signals from the keyboard, etc. and signals from each element described later; 2 receives character codes via cput; and when it receives character codes, it converts the vector information of the character corresponding to that code into dot information. Convert to C
A character conversion unit that returns to the PUI, 3 is a RAM that stores the character dot information converted by the character conversion unit 2, 4 is a RAM
This is a management table (memory) for managing the character dot information stored in 3.

FIG. 2 is a flowchart showing the operation of CPIII.

A series of control procedures of the present invention will be explained with reference to FIG.

The process starts when the CPU inputs a request for character conversion from the keyboard or the like, and the old CP checks in step Sl whether or not the character to be converted is registered in the management table 4. W 6! If not, the CPUI sends the character code to the character converter 2 in step S2. Then, in step S3, cput stores the character dot information returned from the character converter 2 in the RAM 3. Next, in step S4 (: PUl registers the character information stored in RAM 3 in the management table 4, and in step S5
t outputs the character dot information.

If the conversion target character is registered in the management table 4 in step S1, the process advances to step S6, where CP old is R.
The corresponding character dot information stored on AM3 is output.

[Effects of the Invention] As explained above, according to the present invention, characters once converted from vector information to dot information can be retrieved directly as dot information from the second time onwards, so conversion time is shortened and the speed is high. Can be converted into characters.

Claims (1)

[Claims] A character conversion means that stores a plurality of pieces of character information as vector information, a storage means that stores character dot information converted by the character conversion means, and management that manages the character dot information stored in the storage means. and if the character generation requested character information is managed by the management means at the time of a character generation request, the corresponding character dot information is generated from the storage means, and if it is not managed by the management means, the character dot information is generated by the character generation means. 1. A character information generating device comprising means for generating character dot information.
