Abstract

PURPOSE:To enable an operator to make a fair copy quickly and easily by reading the content of a coding sheet, recognizing and interpreting parameter of characters etc. and the content of instructions separatively as character recognizing section and instruction interpreting section, and combining and displaying the recognized and interpreted parameter of characters etc. and instructions. CONSTITUTION:The content of a coding sheet 1 is read optically by a photoelectric conversion section 2, converted to electrical image signals and stored in a memory section 3. As it is determined beforehand that characters are inputted, label part and parameter part are cut out as characters and recognized and interpreted by a character recognizing section 4. An instruction section makes a histogram on vertical direction in one line of a memory section in a histogram forming section 5, and at the same time, detects values above a specified threshold value, and sends out the detected information to an instruction interpreting section. The instruction interpreting section 6 interprets that it is a DI instruction basing on the information. THe content recognized by the character recognizing section 4 and the instruction interpreted by the instruction interpreting section 6 are combined and displayed in a display section 8.

[Problem that the invention seeks to solve]

Conventional program input devices are configured as described above, so when inputting data, the operator must alternately view the original (Fig. 5), the keyboard, and the display while inputting data, which requires a great deal of effort and time. Furthermore, even when using a character recognition device, it is necessary to clean up the program according to the character types read by the character recognition, and even with this clean written program, there are many misreadings and jets (unrecognized), There was a problem in that it required correction after recognition.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. Fig. 1 is a block diagram of the blow 2 configuration of the program input device according to the present embodiment, Fig. 2 is a table showing an example of a coding sheet pattern, and Fig. 3 is a table showing the state of writing on the coding sheet shown in Fig. 2. , FIG. 4 shows a recognition mode diagram of the instruction section.

In each of the above figures, the program input device according to the present embodiment includes an instruction section (22) formed of an instruction section that corresponds to an instruction of an input program and marks the corresponding position of an instruction that uses this program; Each parameter section (23) is provided with a parameter column in which parameters corresponding to the above command are written, and the parameters corresponding to the above command are entered as characters in the parameter section (23). 1), a photoelectric conversion unit (2) that optically reads the program written on the coding sheet (1) and converts the read image into an electrical image signal, and the photoelectric conversion unit (2) a memory unit (3) that stores the image signal converted in the memory unit (3); and character recognition that extracts and recognizes the content in the parameter unit (23) of the program from the image signal stored in the memory unit (3) as a character. a histogram generation unit (4) that takes a histogram of the contents of the instruction part (22) of the program among the image signals stored in the memory unit (3);

The above coding sheet (1) includes a label part (21),
It includes an instruction section (22) and a parameter section (23), and the instruction section (22) is provided with columns corresponding to each instruction in advance. Since random characters are arranged in the label section (21) and parameter section (23), the characters are written in accordance with the type of character recognized and read like the conventional character recognition device.

Next, the operation of the program input device according to this embodiment will be explained based on the above configuration. First, a coding sheet (1) (
As shown in FIG. 3, a coding sheet (1) corresponding to the blockrum is created by filling in the blanks of the instruction section (22) corresponding to the instructions (see FIG. 2) as shown in FIG.

The system is divided into a character recognition section and a command decoding section to recognize and decode the characters, and combines and displays the parameters of the recognized and decoded characters and commands, so all characters can be recognized and decoded by character recognition and reading characters. There is no need to transcribe according to the type (the command section only needs to specify the position corresponding to the command with a mark), and the operator can quickly and easily transcribe. In addition, since the command section does not perform character recognition but simply takes a histogram to recognize the position, the recognition rate of this part can be improved, the overall recognition rate is improved, and the time required for correction is shortened by eliminating the need for corrections. You can easily input programs with .

Furthermore, it also has the effect of not requiring any manual key operation.
