Abstract

PURPOSE:To make it unnecessary to execute an input manually many times, by storing manually a character which cannot be read. CONSTITUTION:When a dissidence signal is outputted and a mobile base 10 is stopped, a character which cannot be read is inputted manually by a user by means of a key operation, but when it is inputted once, when a character which cannot be read appears again, a one character data outputted from an image sensor control part 1a is compared first with the character data of a dissidence character data storage part 37 by a comparing part 36. Accordingly, if coincidence exists, its corresponding character code is sent automatically and directly to a control part 30 from the comparing part 36 and it is unnecessary for a user to input it by a key operation. In this way, when the character which cannot be read is brought to a key input from a keyboard part 42 once, the character which cannot be read and the character code are stored, therefore, when the character which could not be read previously appears again, even if a key input is not executed, the character code is sent out automatically, therefore, the speed-up of the read time can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a reading device that can automatically read programs and the like.

[Background of the invention]

In recent years, technological advances in personal computers have been remarkable, and high-performance products are now available at relatively low prices.

It has become widespread.

However, even though you have purchased a computer, it is extremely troublesome to operate the keyboard and type in the programs yourself, and in particular, typing in long programs such as those found in magazines wastes a lot of time.

On the other hand, it is estimated that a large percentage of computer users own a printer, and in light of this current situation, in addition to the print head, an image sensor is placed on the printer's movable carriage, and the platen is installed. Reads the characters and figures on the original placed in the computer, and reads the CR via a computer.
Proposals have been made to make personal computers easier to use by making it possible to display TK characters, etc., thereby eliminating the need to operate a keyboard and draw characters, etc. on a CRT. However, there is a strong desire among Pancomputer users to take this even further and to reduce the time and burden of program input as much as possible, in other words, to be able to automatically input programs.

However, the programs published in magazines, etc. have various problems such as small fonts, parts that are unclear, and programs being divided into left and right columns on one page, making it difficult to put them to practical use. It has been difficult to realize a device capable of automatic program input at low cost.

[Purpose of the invention]

In view of the above circumstances, it is an object of the present invention to provide a reading device that can automatically input programs and the like at low cost, and can automatically input characters that cannot be read by manually inputting them once and then automatically inputting them the next time.

[Key points of the invention]

In the present invention, a reading means such as an image sensor is provided on a movable table that moves along a platen on which a document is set, characters that cannot be read are manually input using an input means, and the read data of the unreadable characters is read by the reading means. and the character code of the manually input character, and when a new character is read, the read data of the read character is compared with the stored read data, and if they match, the previous character code is used. is output, and if there is no match, the just-read data is output as is.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. First of all, FIG. 1 shows an overall perspective view, and the frame indicated by the broken line in the center of the drawing has almost the same shape as the cassette in which the thermal transfer ink tape of the thermal transfer printer is loaded, and includes the image sensor 1, lens barrel 2, This figure shows the outer shape of a cassette 7 in which a white light lamp spot light generator 4 and the like for illuminating the original are arranged. 8 is a thermal head fixed to the movable table 10 with screws, etc.; 9 is a hub for feeding the thermal transfer ink tape; when a thermal transfer ink tape cassette (not shown) is replaced with the cassette 7 and set on the movable table 10, the ink is transferred. It is designed to fit with the reel shaft around which the tape is wound. Below the moving table 10 is a gear mechanism (
(not shown), the moving table 10 heads down during printing, and the gear mechanism engages with the rack gear 11 provided on the main body, and as the moving table 10 moves on the guide shaft 12, the hub 9 also rotates. A reel shaft (not shown) around which the thermal transfer ink tape is wound rotates to send out the ink tape. Further, 13 is a feed wire for the moving table 10, 14.14 is a pulley that supports the feed wire 13, 15 is a platen, 16 is a motor shaft, 17,
17 is a paper feed gear, 18 is a manual paper feed knob, 19
35a is a paper supply port, and 35a is a setting unit for setting the line pitch and the like.

FIG. 2 shows the image sensor 11 lamp 3. 2 is a partially cross-sectional plan view showing the arrangement relationship of a thermal head 8, a document 20, etc., and the lens barrel 2 into which the image sensor 1 is inserted is not obstructed by the thermal head 8 fixed to the movable table 10 during reading. The reading unit 20a on the original 20 is imaged by the optical lens 21 in the lens barrel 2 onto the light receiving unit in the image sensor 1 via the infrared cut filter la and the protective glass (not shown). . Further, the lamp 3 emitting white light is arranged so as to illuminate the reading section 20a. 24-bit MO as image sensor 1
It uses an 8-inch line sensor and has an optical lens of 21
A wide-angle bright single lens with f=8fi, Fl, 0 is used. By using such an optical lens, the lens barrel 2 could be made smaller and lighter, and could be formed to have a length of approximately 301 m and an outer diameter of 10 mm. Therefore, it could be accommodated in the cassette 7 measuring 40 x 60 x 151y. The cassette 7 has a hole 7a on the bottom surface for escaping the hub 9 when the cassette 7 is set on the moving table 10, and inside the cassette 7 there is an image sensor control unit 1a (described later) that controls the image sensor 1. A printed wiring board (not shown) is provided with a connector (not shown), and one end of the connector is bent and protrudes from the back of the cassette 7. It is contact-connected to a provided flexible connector (not shown) and connected to various circuits to be described later. Further, a spot light generator 4 for transmitting a spot light is disposed in a portion of the original to be read 20 facing the image sensor 1. An LED (light emitting diode) 5 having a vertically elongated light emitting surface is provided, and the document 20 is illuminated with rectangular light like a block cursor.

Note that the LED 5 emits colored light such as red light and green light. Furthermore, a colored lamp or a colored filter may be used instead of the LED.

Next, FIG. 3 shows the overall circuit diagram.

The image sensor 1 is controlled by the image sensor control section 1a, and the read data is sent character by character from the image sensor control section 1a to the comparison section 36 and the mechanism control section 3.
5 is output. The character data storage unit 32 stores character font data and the corresponding 1-byte character code.
The comparison/discrimination unit 31 sequentially compares the read character data sent via the buffer 38 with each character font data in the character data storage unit 32, and if there is a match, it is stored as an S code or the like. The corresponding character code is sent to the control unit 30. The control unit 30 sends the character code to the personal computer body 41 connected via the interface 40. On the other hand, if they do not match, the comparison/determination section 31 outputs a mismatch signal to the LED drive section 33.
receives this and causes the LED 5 to emit light. This discrepancy signal is also sent to the mechanism control unit 35 that controls the mechanism of this device, such as the rotation of the moving platen 15 of the movable table 10. Upon receiving this discrepancy signal, the mechanism control unit 35 stops the movement of the movable table 10. Stop after going slightly backwards.

Further, the one character data from the image sensor control unit 1a is compared with the unmatched character font data in the unmatched character data storage unit 37 by the comparison unit 36, and if there is a match, the character code corresponding to the unmatched character font data is compared. The data is sent from the unit 36 to the control unit 30 which is controlled by a control program in the storage unit 39. If a match is found, the one-character data is sent to the buffer 38, and if the comparing and determining section 31 outputs the above-mentioned mismatch signal as a result of comparison and discrimination, this mismatch signal is also sent to the control section 30, so that the user can press the keyboard. The user visually confirms and inputs the characters illuminated by the LED 5 from the section 42. In response to this, the control unit 30
One character data in the buffer 38 (which becomes the unmatched character font data) and the character code of the corresponding input character are put into the unmatched character data storage section 37, and the pants 7
38 is cleared, an off signal is sent to the LED drive section 33 to turn off the LED 5, and a restart signal is sent to the mechanism control section 35 to restart the mechanism such as the moving table 10. In this case, the image sensor 1 starts reading after the movable table 10 has moved backward by the amount of time it was stopped (that is, from a new character).

Further, the setting unit 35a allows the mechanism control unit 35 to variably set the paper feed pitch, head feed pitch, initial position and moving distance of the moving platform 10, and in particular, when printing on a document, etc. The line pitch of programs, etc. that are being read differs depending on the magazine, etc., so if the line pitch setting is first made to the mechanism control unit 35 using the setting unit 35a, the platen 15 will rotate when one line is read and the next line will be read. The paper is fed to a position where it can be read. Also, even if the machine language is printed in a left column and a right column on one page, as in Progera, if you change the line length setting in the setting section 35a, you can read only the left column first, and then read the left column first. When the position of the moving table 10 is set so that the image sensor 1 can read from the first character of the first line in the right column, the right column is read.

Next, the operation will be explained. If there is a thermal transfer ink tape cassette on the movable table 10 when used as a printer, first remove it and set the cassette 7 on the movable table 10. Then, the original 20 is inserted through the paper supply port 19 and set on the platen 15.

When a reading switch (not shown) is operated, the moving table 10 moves to the home position (the left end in FIG. 1) and raises its head. Therefore, the rack gear 11 and the hub 9 are not coupled via a gear mechanism. In this way, as the moving table 10 moves, the reading section 20 on the original 20 is sequentially illuminated by the lamp 3.
a is read by the image sensor 1. When one line has been read, the moving table 10 returns to the left end and the paper is fed.Similarly, the apparatus of this embodiment has a paper feeding inch and a head feeding width of □.
The image sensor 1 (in the direction perpendicular to the direction of movement of the moving base 10) in which 24-bit light-receiving sections are arranged vertically is used. When reading 4.2311, the resolution is 5.67 lines/n, and if n = 1, the head feed is i inches, and the image sensor 1 moves by 0.176 fl to read one line.

When one line is read, the paper is advanced by the line pitch and the next line is read in the same way. Note that in order to be able to read even very small characters in the program, an image sensor 1 with high resolution may be used, and a high-performance pulse motor may be used.

Now, when the movable table 10 moves and the image sensor 1 starts reading, the image sensor control section 1a receives the resistance data and sends the data one character at a time to the comparison section 36.In the initial state, the mismatch character data storage section 37 Since the content of is cleared, the comparison unit 36 sends one character data to the buffer 38.

The comparison/determination unit 31 sequentially compares the 1-character data from the buffer 38 with the font data of each character stored in the character data storage unit 32, and if there is a match, it generates a 1-byte character code corresponding to the font data. It is sent to the control unit 30. In this case, since the typeface of characters such as programs printed on the originals 20 differs slightly depending on the various types of originals 20, the comparison/discrimination unit 31 determines that they match if they meet predetermined requirements. The control section 30 sends this character code to the personal computer main body section 41 via the interface 40. In the personal computer main body section 41, the same processing as when an input is made by key operation from the keyboard section 42 is performed.

On the other hand, if there is no match, the comparison and determination section 31 outputs a mismatch signal to the control section 30, the LED drive section 33, and the mechanism control section 35. Upon receiving this discrepancy signal, the LED drive unit 33 causes the LED 5 to emit light, the mechanism control unit 35 immediately stops the movement of the moving table 10, and the image sensor control unit 1
Based on one character data sent from a, the moving table 10 is moved backward so that the center line of the block cursor emitted by the LED 50 is aligned with approximately the center line of one character, and then stopped.

From this point on, the user visually confirms, for example, the character of the block cursor that is illuminated in green, and inputs the character by operating the keys on the keyboard section 42.

At this time, the lamp 3 may be on or off. In a situation where the control unit 30 receives a mismatch signal from the comparison/discrimination unit 31, when a character code based on a key operation is inputted via the interface 40 or directly, the control unit 30 stores the contents of the buffer 38 in the mismatch character data storage unit. 37, and also writes the input character code in association with it. Thereafter, the control section 30 clears the buffer 38, sends an off signal to the LED drive section 33 to turn off the LED 5, and sends a restart signal to the mechanism control section 35 to move the movable table 10 again to perform reading.

The user manually inputs \, but once a character that could not be read first appears again, the one character data output from the image sensor control unit 1a is determined by the comparison unit 36 to be a mismatched character. It is first compared with the character data in the data storage section 37, so if there is a match, the corresponding character code is automatically sent directly from the comparison section 36 to the control section 3o, eliminating the need for the user to input it by key operation. .

As described above, in this embodiment, the image sensor 1 and the like are provided on the movable table 1° of the printer, and the comparison and discrimination section 31 compares and discriminates the read data of one character with the data stored in advance in the character data storage section 32. Therefore, it can be manufactured relatively cheaply.

When the image sensor 1 reads the program etc. of the document 20, if there is a character (including symbols) that cannot be read, the moving table 10 will stop moving backwards and the LED 5 will light up the unreadable character in red, green, etc. The keyboard section (including touch panels, etc.) allows you to clearly see unreadable characters.
You can quickly input from 42.

In addition, the light from the LED 5 illuminates characters that cannot be read accurately in the form of a block cursor, so even small characters can be clearly identified to be input.

In addition, once a character that could not be read from the keyboard section 42 is manually pressed, the unreadable character and character code are stored, so if a character that could not be read first appears again, the user does not have to manually press the key. Since the character code is automatically sent, reading time can be speeded up.

Further, since the setting section 35a allows setting the line pitch, line length, position of the movable table 10, etc., even if the line pitch etc. differ depending on the document 20, it can be quickly handled and read smoothly.

〔Effect of the invention〕

As explained above, according to the present invention, the reading means is installed on the movable table, and the read data of one character (including symbols) is compared and determined with the data in the character data storage section in the comparison and determination section, so it is inexpensive. It is now possible to manufacture characters that cannot be read by inputting them manually using an input means, storing the read data of the unreadable characters by the reading means and the character code of the manually input characters, and then creating new characters. When reading, the read data is compared with the stored read data, and if they match, the previous character code is output, eliminating the need for manual input many times and speeding up the reading time.
