Description

[Detailed explanation of the idea] [Industrial application field]

This invention is a phototypesetting machine (hereinafter referred to as a phototypesetting machine).
Regarding.

[Conventional technology]

Conventionally, when printing materials with predetermined line lengths are created using a phototypesetting machine, even if printing is performed using only the specified Q number (character size) and feed amount, the line lengths will be too large or too short. cases often occur. In order to eliminate this excess or deficiency and match the specified line length, select the feed amount (e.g., close printing), change the Q number (e.g., change the magnification of the main lens, zoom, etc.),
Possible means include transforming the characters. In any case, it is necessary to repeatedly go through trial and error to find the conditions for typesetting through preliminary calculations (referred to as allocation calculations). An example of a phototypesetting machine capable of performing close-up printing is disclosed in Japanese Patent Application Laid-Open No. 115817/1983. This includes a character symbol, a neighboring area of the character symbol,
A dial is prepared in which the other areas can be optically identified, and for each character to be printed, the neighboring area is detected, and the amount of feed between adjacent characters on the printed material ( I am trying to find the filling amount). However, with this method, although it is possible to obtain the feed amount (filling amount) for each character spacing, it is not possible to obtain the feed amount to obtain a printed matter that fits within a predetermined line length. There is a similar one in Japanese Patent Application Laid-Open No. 52-51933. This is done by dividing the character symbol to be printed into upper, lower, left, and right sides from the center, creating data for each character width, and using this data to obtain the amount of feed (filling amount) between adjacent characters. It has become a thing. Therefore, as in the case described above, the amount of feed between characters can be easily obtained, but it is impossible to obtain the amount of feed required to obtain a printed matter that is just over or under the designated line length.

[Problem that the idea aims to solve]

Creating appropriate printed matter based on the various formatting conditions described above not only places a heavy burden on the operator, but also relies heavily on the operator's intuition and experience, neglecting prior preparations such as layout calculations. There were issues such as the process being unprofitable. This invention was made in order to solve the above-mentioned problems, and the object is to provide a phototypesetting machine that can omit layout calculations that take into account various typesetting conditions and that dramatically improves printing efficiency. With the goal.

[Means to solve the problem]

This invention includes a formatting condition memory that stores n sets of formatting conditions, a line length memory that stores the number of characters to be printed in one line to be printed, and the designated line length thereof.
a line length determination circuit that compares each of the n sets of printing line lengths calculated based on the n sets of typesetting conditions and the number of characters to be printed in one line with the printing line length in a control unit, and selects the best condition; , based on this best condition,
The printer is equipped with a formatting condition selection circuit for selecting one set of formatting conditions from a formatting condition memory, and printing is performed under the formatting conditions selected by the formatting condition selection circuit.

[Effect]

This invention compares each print line length of n sets calculated by the control unit with a specified line length specified in advance based on the n sets of formatting conditions and the number of characters to be printed in one line, and based on this result, One set of the best formatting conditions is selected from n sets of formatting conditions, and printing is performed based on this.

【Example】

An embodiment of this invention will be described below. In FIG. 1, numerals 1 to 6 show examples of printing with arbitrary line lengths, and in the figure, for convenience, characters are represented by their virtual body shapes (square frames). 2 to 4 are examples in which the line length L is reduced to 1, and FIGS. 5 to 6 are examples in which the line length is extended. 1 is when printing in 32Q/true solid set, 2 is when 32Q/true characters are reduced by 1/32 em (1/32 of full-width) from the specified feed amount of 32Q/true character. In this example, the line length is (L-l ₁ ). 3 is an example of 32Q, long type 1 (character width reduced by 10%), and printed as a solid set.
The line length is (L-l ₂ ). 4 is 32Q long body No. 1, the feed is -1/32m from the predetermined feed amount, and the line length is (L-l ₃ ). Here, l is l ₁ <
The relationship is l ₂ < l ₃ . In addition, example 5 is an example where the line length is expanded in the opposite direction, and the line length is (L + l ₄ ) when the specified feed amount is set to +1/32 M for 32Q / real characters.
becomes. 6 is 38Q, long body number 3, (character width reduced by 30%)
In this example, the line length is (L+
l ₅ ). Here, there is a relationship of l ₄ < l ₅ . In this way, even with the same 32Q, there is a difference in line length L between when the regular solid feed is performed and when the long deformable lens is inserted into the optical system. Similarly, when the feed amount is increased or decreased by 1/32 em, a difference occurs. Also, even if the main lens is changed from 32Q to 38Q and the long body No. 3 modified lens is used for solid feed, a similar line length can be obtained. Of course, the magnification of the deformable lens (1
Many combinations other than the example shown in Figure 1 above can be obtained depending on the shape (elongated, flat, oblique), main lens magnification, etc., so a variety of combinations can be obtained. be able to. As an example of feed amount, the value 32 of 1/32 em simply means how many parts one character (one em) is divided into, and the value 32 has no special meaning. For example, when the line length is L, the main lens magnification is 32Q, and the number of characters to be printed is 9, the amount of feed from A to A1 in Figure 1 must be calculated in advance to match the specified line length L. It is impossible to judge. In the case of Figure 1, n=6, but if you select only the one closest to the desired L and print it, you can proceed with the desired printing work without having to calculate the allocation in advance. can. The above example was a simple example of 32Q identity, solid feed, line length L, and number of characters 9 (in this application, the above conditions are referred to as typesetting conditions), but it is also called leaflet typesetting or odd article typesetting. Many complex specifications can be seen during typesetting. Figure 2 shows an embodiment of the present invention, in which multiple printing line lengths are calculated based on various formatting conditions as shown in Figure 1, and compared with the specified line length L, printing under the best conditions is determined. It was made so that things could be obtained. In the figure, 1 is a light source, 2 is a condensing lens, 3 is a main lens, 4 is a deformation lens, 5 is an imaging lens,
Prisms 6 and 7 and travel prism 8 print characters on a dial 9 onto a photosensitive material wrapped around a photosensitive material drum 10 via an optical system such as a main lens and a deformable lens. Note that when the light source 1 is a continuous light source, a shutter is required, but when it is a flash lamp, this shutter is not necessary. Reference numeral 11 denotes a character feed drive motor that moves the travel system 12T in the lateral direction, and 12 a line feed drive motor. Drive commands are given to each by the feed control circuit 13, and based on these drive commands, the sensitive material drum 10 is moved. Rotate by a predetermined amount to move the travel system 12T by a predetermined amount. 14 is a register for storing the current printing position; 15 and 16 are a deformation lens switching mechanism and a main lens magnification switching mechanism. These elements are common, and this application is not limited to them. For example, in addition to the main lens 3 and the deformable lens 4, there is no problem in adding a magnifying lens or other auxiliary lens, and in such a case, 15, 16
A lens switching mechanism shown in will be installed.
In any case, the magnification of the character image stored on the dial 9 is converted through an optical system including various lenses, and the image is printed on the photosensitive material of the drum 10. Next, the configuration of the control system will be explained. The control unit CPU gives various operation commands to the feed control circuit 13, the deformable lens switching mechanism 15, and the main lens magnification switching mechanism 16, and also controls the operation of the entire apparatus based on information from these and information from each circuit component described later. control. And this control unit CPU
is n stored in the formatting condition memory SM, which will be described later.
The formatting conditions of each set are read out, and each formatting condition of the read n sets and the line length memory described later are stored.
Based on the number of characters to be printed in one line read from the LLM, each print line length of n sets under each condition is calculated and stored. WM is a character width memory that stores the character width of the character to be printed, detected by a character width detection means (not shown), and transmits it to the control unit CPU. PB is a print button, CB is an input button for various formatting conditions, and n sets of data such as "true solid set" and "true body - 1/32M feed" are to be input, and as described later, they are printed in one line. Information such as the number of characters and specified line length can also be entered using this input button.
Input from CB. Note that the format of the button can be changed in various ways depending on the format of the input information, and does not limit the scope of the present invention. SM is a formatting condition memory that stores n sets of data with various changes in the contents of this data as formatting conditions, with one set of data including the feed amount, lens magnification and shape in the optical system for the character image to be printed. , these formatting conditions are input using the input button CB.
The LLM is a line length memory that stores the number of characters to be printed on one line and its specified line length, and the specified line length and number of characters are similarly input using the input button CB. CC is the control unit CPU which is the formesetting condition memory SM.
n sets of formatting conditions and line length memory read from
Each printing line length and line length memory of n sets calculated based on the number of characters printed in one line read from LLM
A line length judgment circuit that compares the specified line length stored in LLM and selects the best condition.
This is a formatting condition selection circuit that selects a formatting condition for a set from a formatting condition memory SM. Also, if you want to specify the spacing between multiple lines as shown in Figure 1, enter it using the input button CB and store it in the line spacing memory SLM.If it is not necessary, use the print character Q. The control unit CPU issues a command to automatically set the line spacing corresponding to the number. DS is a condition display device that displays the formatting conditions when a large number of formatting conditions have been input or stored in the formatting condition memory SM. Next, the operation will be explained. First, use the input button CB to input the feed amount of the n sets of character images to be printed, data regarding the magnification and shape of the lens in the optical system, the number of characters to be printed in one line, the specified line length, etc. to the formatting condition memory SM and the line length memory, respectively. LLM
input and memorize it. The control unit CPU reads n sets of formatting conditions stored in the formatting condition memory SM and the number of characters to be printed in one line stored in the line length memory LLM, and based on these, prints n sets under each condition. The line lengths are calculated and stored. That is, the print line lengths 1 to 6 in FIG. 1 are calculated. Then, the line length judgment circuit
The CC compares each of the n sets of printed line lengths calculated by the control unit CPU with the specified line length stored in advance in the line length memory LLM, selects the best condition, and outputs it to the formatting condition selection circuit SP. do. This typesetting condition selection circuit SP
The formatting condition memory is based on the best conditions.
One set of formatting conditions is selected from n sets of formatting conditions stored in the SM and transmitted to the control unit CPU. Once the preparations are completed, the operator uses the print button PB to perform character input and printing operations for actual printing. Then, the control unit CPU drives the feed control circuit 13 or, if necessary, the deformation lens switching mechanism 15 and the main lens magnification switching mechanism 16, based on the stored formatting conditions, to create a printed matter. In this case, the printed matter obtained is only one line with the best line length, so the time required to create the printed matter can be significantly shortened, but if the line length is not determined in advance, the line length You just need to set this and repeat the printing process. In the above embodiment, the horizontal writing mode shown in FIG. 1 is taken as an example, but it is clear that the same applies to the vertical writing mode. In addition, although the above explanation describes an example in which typesetting is performed for all characters in one line, it is also possible to typesetting any number of characters using the same method, and by selecting the number of characters, various line lengths can be created. This has the effect of making it easier to realize.

[Effect of the invention] As described above, according to this invention, the control unit calculates n sets of formatting conditions read from the formatting condition memory and the number of characters to be printed in one line read from the line length memory. The printing line length is compared with the specified line length, and based on the results, one set of formatting conditions that is the best is selected from the n sets of formatting conditions, and printing is performed based on this. As a result, when creating printed materials with line lengths specified in advance, there is no need to perform layout calculations that take into account various formatting conditions or troublesome operations, reducing the burden on the operator and reducing manual labor. Eliminate mistakes and unnecessary processes,
Printed materials with various Q numbers and feed amounts can be selected and worked on under optimal conditions at the designer's or operator's discretion.
