Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an image output device having a plurality of character patterns.

[Prior Art] Conventionally, for example, in a character printing device having a plurality of font pattern patterns, when a character pattern set command is received from a data controller, if the character pattern set is not stored, a predetermined selection is performed. This method selects and outputs one character pattern set from the existing character pattern set, or outputs a conversion request for the character pattern storage procedure.

[Problems to be Solved by the Invention] However, this method has the disadvantage that there is a high possibility that an unintended character pattern will be output.

The present invention solves the above-mentioned problems and provides an image output device that can output an intended character pattern and, when the character pattern cannot be changed, select a character pattern that is close to the intended one. The purpose is to

[Means for Solving the Problems] The present invention provides a character pattern storage means for storing a plurality of character pattern groups, a determination means for determining whether a designated character pattern group exists in the character pattern storage means, and means for selecting a character pattern according to character pattern selection criteria designated in advance when it is determined by the determining means that the designated character pattern group does not exist in the storage means.

[Operation] That is, according to the present invention, it is determined whether a designated character pattern group exists in the character pattern storage means.
- It is determined that the designated character pattern group does not exist in the storage means, and character patterns are selected in accordance with the designated character pattern selection criteria.

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

FIG. 1 shows one embodiment of the present invention. Figure 1 shows the basic flow of data. 101 is a host computer (computer) as a data source; 102 is an input buffer that stores human data from the computer 101; and 103 is a CPIJ that performs control calculations and stores RAM and control procedures as shown in FIG. It has a ROM with 104 is a register used for analyzing control commands, 105 is a built-in character generator that stores character information patterns, 106 is a removable character generating means, 107 is a socket as a connection port for the means 106, and 108 is an output terminal. 109 is a printer interface unit that converts the information in the buffer 108 into a printable state; 110 is an output unit that outputs images, etc.; 111 is a printer unit 2 that is controlled by the buffer 108 and performs actual printing. It is.

Figures 2 and 3 show the contents of the built-in character generator.

In FIG. 2, 201 is font information that stores the properties of the font, and 202 is a pattern section that stores patterns for each character.

FIG. 3 shows a more detailed configuration of the font information section 201. That is, a font ID section 301 representing a unique identification of a character pattern set, a character height 302, a character width 303, and a character size 30 represented by character height x character width.
4 and font 305 are stored.

FIG. 4 is a flowchart showing the receiving operation by the CPU 103. FIG. 5 shows a character pattern set instruction command sent from the computer +01 as a data source, where ESCI code 501 represents a control command, 1502 is a code for identifying a character pattern set, and d503 is a code for identifying a character pattern set. This is a code indicating that it is a character pattern instruction command.

The operation will be explained below according to the flowchart shown in FIG.

This flowchart starts by receiving data, and first, in step S1, the received data is transferred to the input buffer 10.
2, and the received code is ES in step S2.
Determine whether it is a C code. If it is not an ESC code, the process advances to step S3, where the code or corresponding character pattern is output to the output page buffer 108 for printing.

When the ESC code is read in step S2, the process proceeds to step S4, where it is determined whether it is a character pattern set instruction command. If it is not a character pattern set instruction command, the process advances to step S5, where processing corresponding to the control command is performed.

In step S4, the character pattern set instruction command (ES
CCid), the font ID information is read in step S6, and the corresponding rD
It is determined whether there is a character pattern set having the value in the character generator 105 and the character generation means 106. If there is a character pattern set, the process advances to step S8, where the corresponding character pattern set is selected. Next, in step S9, it is determined whether the human data has been completed, and if not, the process returns to step S1.

If it is determined in step S7 that there is no corresponding font ID, the process proceeds to step S10, where character generation means 1
An output is sent to the output unit 110 to confirm whether or not 06 can be replaced. If the exchange is possible, the process advances to step Sll, where the character generating means for exchange is also instructed, and if the exchange has been performed, the process returns to step S7.

If replacement is not possible in step 510, step S12
The process then refers to the font information section, instructs the pattern set that is considered to be the closest based on predetermined selection criteria, and proceeds to step S8.

For example, a standard is set to be the closest to the requested character height, the character heights in the font information section of each character pattern set are compared, and the closest one is specified.

Note that the character pattern set instruction command, font rD, etc. in this embodiment are not limited to this embodiment.

In this embodiment, a character pattern exchange instruction is displayed on the output unit 110, but it is also possible to create an exchange request signal to a data source such as a host computer and send out a corresponding character pattern set from the host computer. Alternatively, if there is no removable character generating means, the characters may be read out from a large capacity character pattern storage means such as a disk.

[Effects of the Invention] As described above, according to the present invention, it is possible to prevent the output of unintended characters and symbols, and to obtain an image output device in which character patterns can be easily selected.
