Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a phototypesetting machine having display means for a monitor.

[Background Art of the Invention] A conventional phototypesetting machine having a display means for a monitor captures an image of typed characters, symbols, etc. (hereinafter simply referred to as characters) with an imaging unit, and stores the printed characters in a storage unit. It was written to the refresh memory along with character data and displayed on the display for confirmation. Once confirmed, the characters are printed on the photosensitive material, and the character data, printing position, etc. of the printed characters are stored in the storage section.

Such phototypesetting machines have a function of printing a predetermined number of characters within a predetermined line length in accordance with a predetermined printing format (hereinafter referred to as a typesetting machine).

Hereinafter, a normal method of operating the gear stay eye will be explained with reference to FIG.

(1) Specify the line length L to perform the stay-on.

(2) The character selected from the dial is not actually printed, but is only fed by an amount corresponding to the desired magnification (hereinafter, this operation is referred to as blank printing, and for the sake of explanation, the magnification at that time is blank). The number of prints Q and the line length are called blank print line length l). In the figure, □ indicates a character, SP indicates a space, and the shaded area indicates the remainder for the specified line length L.

(3) Issue a stay-at-eye command.

(4) Based on the keep eye command, the remaining amount is equally divided by the number of SPs, and the allocation amount is determined.

(5) The calculated amount of allocation is added to the above space and sent, and the characters are actually printed (hereinafter referred to as actual printing).

In the above manner, as shown in the figure, the alignment is made to match the designated line length L and printed.

In addition, for example, there is a gear stay eye as shown in FIG.

() I want to print a character string with character size (hereinafter referred to as Q number) Q ₁ and empty printing line length l ₁ as shown in (a) so that it fits within the specified line length L ₁ shown in (b). When,
By equally distributing the difference between the line lengths l ₁ and L ₁ between the subcharacters, the adjustment as shown in (b) is performed.

() Next, as shown in (b), the character string with the number of blank prints Q ₁ and the blank print line length L ₁ is enlarged to fit within the specified line length L ₂ as shown in (c). When you want to print,
By finding a magnification from the ratio of the line lengths L ₁ and L ₂ and scaling the Q number and each feed amount in (b) using this magnification, a position-stabilizing result as shown in (c) can be obtained.

() Next, transform the character string with the number of blank print Q ₂ and the blank print line length L ₂ as in (c), and change the character string without changing the character height T ₂ as in (d) (in this case, long) and specify line length
When you want to print to fit within L ₃ , line length L ₃
By finding the deformation rate from the ratio of and L ₂ and multiplying the feed amount of each character in (d) by this deformation,
A static eye result like (d) is obtained.

[Problems with the background technology] However, the above-mentioned position-stay-eye result cannot be confirmed until it is actually printed and displayed, resulting in mistakes in character input during blank printing, mistakes in setting the specified line length, and unexpected position-stay-eye results. If the printer becomes erroneous, settings must be made again and printing must be performed again, consuming wasted photosensitive material and time, resulting in a reduction in work efficiency. Furthermore, since substantial changes and conversion operations are involved in optical members, such as changes in lens magnification, deformation rate and deformation shape of the deformed lens, operation time during blank printing is required, and an improvement has been awaited.

[Object of the Invention] The present invention enables the user to check the result of the shift by displaying a simulation before actual printing, and also uses a variable magnification lens, a deformable lens,
The image is sized and displayed electronically without driving optical members such as an image rotating prism, and during actual printing, the optical member is driven and set using the calculation data obtained from the simulation results in blank printing, and then printed. The present invention provides a phototypesetting machine that allows the work to proceed.

[Summary of the Invention] The present invention displays characters, symbols, etc. selected from a dial on a display unit via an imaging unit, and

The first step is to display a simulation to check the printing before printing.
A second feature is that the optical member is not driven during the blank printing, and characters at a desired magnification are displayed by electronic sizing, and the contents of the image memory are output to the printer.

By transferring the character data of 9 to the refresh memory 30 and storing it, the printed characters and the characters that have been typed can be displayed, and the printing position can be confirmed.

Next, the operation of the present invention will be explained.

The input section 24 is used to specify the line length for which the adjustment is to be performed. Then, the zoom lens 5 is set in advance to a constant magnification, or characters are drawn from the dial 4 at the currently used magnification and blank printing is performed. The blank printed characters are stored in the buffer memory 28 via the digitizing memory 23 in a state where the character data can be read out character by character.
In the case of a number of JST, the character data is stored as it is in the blank print memory 32, and in the case of a JST of a different Q number, the character data is converted to a separately specified Q number via the sizing control section 31. and stores it in the blank print memory 32.
The contents of the blank print memory 32 are sequentially sent to the refresh memory 30 and sent via the P/S conversion circuit 33.
Display on CRT34.

If you print the required number of characters blank like this,
The input unit 24 sends the stay eye command to the control unit 2.
Send to 5. When the control section 25 receives the stay-at-eye command, the above-mentioned () to () are sent to the calculation section 20.
A command is given to calculate the gear stiffness information such as the allocation amount, magnification, deformation rate, feed amount, etc., using each gear stiffening eye up to the present time.

On the other hand, the control unit 25 controls the display control unit 27,
The character data stored in the buffer memory 28 is sequentially transferred character by character to the sizing control unit 31. The sizing control unit 31 then calculates the size based on the size information calculated by the calculation unit 20.
By sequentially converting the input character data, it is possible to obtain the above-mentioned JST results () to (). The status result is stored in the blank print memory 32 after erasing the blank print character data, and is stored in the refresh memory 30,
The image is displayed on the CRT 34 via the P/S conversion circuit 33. Thereby, the operator can check the stay-at-eye result before actual printing without driving optical members such as the zoom lens 5 and the deformable lens 6, and if the stay-at-eye result is correct, then actual printing is performed.

In this printing, the amount of allocation, magnification, deformation rate, and
By driving the zoom lens, deformation lens, feed drive source, etc. in accordance with the feed amount, etc., and printing on the photosensitive material 15, a desired image stay result is printed. When the main printing is performed, the character data printed by the main printing is stored in the image memory 29, and the refresh memory 30 and P/S
It is displayed on the CRT 34 via the conversion circuit 33. When the actual printing is completed, the empty printing memory 32
The current status results stored in the previous page will be deleted.

Further, in the above explanation, the case where the print result is printed on the photosensitive material has been explained, but in the present invention, the print result can also be output to the printer by connecting the printer. In this case, the shutter 10 shown in FIG. 3, the travel lens system 11, the sensitive material drum 14,
Sensitive material 15, X-axis drive source 16, Y-axis drive source 1
7. Since the feed control unit 18, current position counter 19, etc. are unnecessary, it is different from the concept of the name "phototypesetting machine", but in this application, for convenience, the term "phototypesetting machine" includes these. ”.

The case of printer output will be explained below.
As in the case of the above-mentioned phototypesetting machine, the make-up eye result is displayed as a simulation and confirmed, and if the make-up eye result is correct, the actual printing is not carried out as in the case of the above-mentioned phototypesetting machine, and the printing operation is continued. Then, the stay-stay-eye result is stored in the image memory 29 at the start of the next printing operation, and the stay-stay-eye result is erased from the blank print memory 32 in preparation for the next stay-at-home.

By instructing printer output from the input unit 24, the printed character data stored in the image memory 29 is transferred to the printer buffer memory 35, and output to the printer according to the printer control unit 37.

Note that by transferring the character data in the image memory 29 to the printer buffer memory 35,
Printing can continue even when the printer is in operation, and by sequentially transferring the image memory 29 to the printer buffer memory 35, it is also possible to output continuous printed matter on roll paper.

In this way, although the quality of printer output is slightly inferior to that of the phototypesetting machine, the printing results can be output immediately, and the effect can be great when applied to, for example, captions and flyers. It is.

Furthermore, it is clear that by using a high-resolution printer such as a laser beam printer, it is possible to obtain high-quality prints that are close to the phototypesetting prints.

[Effects of the Invention] As described above, the present invention is capable of displaying and confirming the result of the shift error before actual printing, thereby preventing printing errors and improving work efficiency since it is possible to confirm the printing style. Furthermore, it is very economical because it can be switched between photosensitive material output and printer output depending on the application. Furthermore, since characters are recorded without driving the optical member during blank printing, the printing operation time can be shortened.
