Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a stroke-to-dot type character signal generation device used in a computerized phototypesetting device or the like.

[Prior art and its problems]

As shown in FIG. 1, a conventional stroke->dot type character signal generation device includes a pattern storage device 1 based on stroke information, and a second pattern storage device based on input information that sends out a pattern such as a character when a readout signal is given. A contour stroke information generating device 2 that sends out the contour of a pattern such as a character as stroke information as shown in FIG. (FIG. 2b shows the case where the Y-direction component is stored) and a dot pattern signal conversion processing device that converts the contour information read from the contour information storage device 3 into a dot pattern signal as shown in FIG. 2c. 4, and the conversion to dot information is as follows for the row or column output to be converted:
A conversion method is adopted in which the conversion output is “1” (or “0”) at the first “1” signal, and the conversion output is “1” (or “0”) until the next “1” signal. There is.

In the case shown in Fig. 2, the direction of the stroke/dot conversion process is set to the A direction (X direction) as shown in Fig. 2b, and Fig. 2c shows the pattern of dot information after the conversion process. It is something.

However, according to this conversion method, for example, when generating new characters by composing basic character patterns, or when changing line widths or character patterns, the problem shown in Figure 3a. When the outlines of characters, etc. overlap, the outline information storage device stores it as shown in Figure 3b, and the converted output of the overlapping parts is changed to "0" instead of "1" (or "0"). ” (or “1”), and there was a drawback that the overlapping portion was missing as shown in FIG. 3c.

[Means for solving problems]

The present invention has been made to eliminate this drawback, and includes a device for storing patterns such as characters based on stroke information, a device for reading pattern information from the pattern storage device to generate outline stroke information, and a device for outputting outline stroke information from the device. A discriminator that discriminates and outputs a positive direction component and a negative direction component perpendicular to the stroke/dot conversion processing direction A (X direction or Y direction) in the contour stroke information, and a discriminator that discriminates and outputs the positive direction component output from the discriminator. A first contour information storage device that stores the negative direction component output from the discriminator as a dot signal, a second contour information storage device that stores the negative direction component outputted from the discriminator as a dot signal, and stores information from the first and second contour information storage devices. and a dot pattern signal conversion processing device that simultaneously reads out the information in the stroke/dot conversion processing direction A, adds the read information to an up-down counter, and converts the output of the up-down counter into a dot pattern signal. , the up-down counter counts up in response to the readout signal of one of the contour information storage devices and counts down in response to the other readout signal, and the dot pattern signal conversion processing device counts up all counts when the counter value is other than “0”. This character signal generating device is characterized in that it outputs "1", and when the counter value is "0", it outputs all "0".

and the second contour information storage devices 31 and 32 in the stroke/dot conversion processing direction A, and the readout signal from one contour information storage device, for example 31, counts up, and the readout signal from the other contour information storage device 31 counts up. Let's count down,
An up-down counter that outputs all “1” when the counter value is other than “0” and all “0” when the counter value is “0”. 4 is a dot pattern signal conversion process similar to the conventional device. It is a device.

Now, to explain the operation when synthesizing the character 〓 and the character 〓 from the character 〓, the character pattern signal 〓 based on the stroke information and the character pattern signal 〓 are stored in the pattern storage device 1 according to the command signal. Outline stroke information generator 2

If the stroke information read from the
If the stroke information read from is "1", it is counted down, and if the counter value is not "0", all "1"s are output to the dot pattern signal conversion processing device 4, and if the counter value is "0", it is outputted to the dot pattern signal conversion processing device 4. All “0” dot pattern signal conversion processing device 4
The dot pattern signal conversion processing device 4 forms a desired dot pattern signal as shown in FIG. 5d.
