Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a phototypesetting machine and similar machines that can easily and beautifully print appropriate characters with character spacing narrower or wider than normal character spacing. This is what I did.

Recently, a process called hitome printing has been frequently used in advertisements, general printed matter, etc., and phototypesetting machines and similar machines are required to be able to easily perform this process.

That is, the characters accommodated in the Japanese text dial of a conventional phototypesetting machine occupy an area 1 (hereinafter, the frame of this area 1 is referred to as the body area), as shown in FIG. 1A.

) in most cases, the center (or center of gravity) of the character is located near the center point 2 of the text, and most phototypesetting machines' optical axes are designed to pass through this center point 2.

For example, if you try to print each character at its character width (the interval shown by the dotted line in Figure 1 A) as shown in Figure 1, the character width of the first printed character and the character width of the next character to be printed are You have to perform the cumbersome operation of adding them together and sending only the halved amount.

Therefore, for kana, numbers, punctuation marks, and some other kanji, as in conventional European dials, each character is placed at one end of the body area 1 of the character (in this example, the left end), as shown in Figure 1 C. However, this can be at any end, top, bottom, left, or right depending on the assembly direction.

) and further classify and arrange each character according to character width.

(Although the character widths of each character may not be considered to be the same character width in a strict sense, hereinafter characters with the distance-feed amount are referred to as characters with the same character width.

) In other words, when using such a dial, when printing is done by the character width of each character as shown in Figure 1, it is only necessary to advance by the character width each time each character is printed. Phototypesetting machines are equipped with a mechanism that detects the character width of the characters on the dial, calculates the character width of the printed characters, and advances by that amount. Typesetting like the first ward is possible without any problems.

However, using a dial like the one shown in Figure 1 C above,
Even if you use a phototypesetting machine equipped with the above-mentioned mechanism for printing European characters, if you try to print by increasing or decreasing the character spacing from the character width, you will not be able to print with even character spacing. This required complicated manual operations.

In other words, in a phototypesetting machine equipped with the above-mentioned European printing mechanism, a main lens with various magnification ratios is selected to make the characters on the dial a desired size, for example, Q grade, and further settings are made. By setting the feed amount to Q teeth, the character width of the characters on the dial is detected and converted to the feed amount in Q class, so it is possible to set the set feed amount to be smaller or larger than the Q teeth. By using q teeth, it is possible to print with a feed amount that is different from the character width of the characters to be printed.

However, in this case, if the character size is Q class, the set feed amount is q teeth, and the width of the character to be printed in Q class is L teeth, then the feed amount at that time is l teeth, then the feed amount is 1! =qL/Q
・・・・・・・・・・・・・・・・・・■ becomes,
The feed amount is reduced in proportion to the character width,
Alternatively, the larger the character width is, the more the feed amount is increased, and the more the character width is increased, the more the feed amount is increased.

Therefore, when printed, the spacing between each character is not equal, and as shown in the European printing example in Figure 1-2, the spacing between characters is uneven before and after the small character width of lowercase letters [il]. , resulting in unsightly printed matter.

Therefore, the width of the characters on the entire dial can be expressed as a series or.

It is not an absolute value called a tooth, but a full-width (which refers to the body area indicated by 1 in Fig. 1, and is also called 1 type M.

) to the number of new EMs (e.g. full-width IV
16EM, half-width is 8/15EM) If it is displayed as M and the size of the printed character is Qi, then the character of the printed character.

Width tooth is L = MQ ・・・・・・・・・・・・・・・・・・
・・・・・・・・・・・・■.

Therefore, if you want to decrease the feed amount, or if you want to increase the character spacing, the feed amount to increase is expressed as the number of EM m, and if you want to decrease it, add a negative sign to this m, and if you want to increase it, add a stop sign to it. Then, the character width is L - (M + m) Q ・・・・・・・・・・・・・・・
・・■ make it rain.

If we do this, the field is the ratio to the full-width as mentioned above, and if the character size Q does not change, mQ will always show a constant number of teeth, so we will send it based on the calculation result of this formula 0. If this is done, the character spacing between each character becomes equal, and a printed matter as shown in Fig. 1 (e) can be obtained.

However, with conventional phototypesetting machines or similar machines, 1
There is no way to decrease or increase the same amount of feed from characters with different character widths, so in the end, either manual feed operation based on the prior layout calculation as described above or the method shown in Figure 1, 2. The only options were to compromise on printed matter, or to use an expensive typesetting machine equipped with arithmetic circuits to perform calculations like Equation 0.

In view of these points, the present invention provides the first method using a very simple method.
This invention was made to provide a phototypesetting machine that can produce printed matter as shown in Figure E, and a similar machine thereof.Hereinafter, the case where the present invention is implemented in a phototypesetting machine will be explained in detail with reference to the drawings. .

The dial is. In the illustrated example, the main plate 22 and the sub-plate 23 are placed on the upper character frame 32 and can be moved left and right on the lower character frame 32. The desired character is moved back and forth on a rail 34 fixed to the optical axis to bring the desired character to the optical axis position.

The components described above are those commonly used in ordinary phototypesetting machines, and are not limited to those shown in the figures.
, sub-plates 23 are shown, but dials for phototypesetting machines are available in various sizes and shapes, and the present invention is not limited to those shown.

35 is a code plate that stores the character width of the characters on the dial as a code. In this example, as shown in the figure, it is attached to a support 36 fixed to the lower character frame 33, and as the dial moves in the front and back direction, the code plate Moving.

3738 is a holding mechanism for a code detector such as a light emitting element and a light receiving element for detecting the code on the code plate 35. Of these, the holding mechanism 37 for the light emitting element is fixed to the body of the phototypesetting machine. , the holding mechanism 38 of the light receiving element is 1 drive source 3
By rotating 9, it can be moved up and down between guide plates (not shown).

Note that the code plate 35 and the detector are always connected to the code plate 35.
The phototypesetting machine's main body cover is designed to block light to an extent that does not interfere with code detection.

Numeral 40 is a tab value setting key for inputting the amount by which the character spacing is decreased or increased (hereinafter simply referred to as a tab value); 41 is a driving source 39 that is driven by a predetermined amount based on the value input from the tab value setting key 40; The character width detector movement control circuit 42 that moves the light-receiving element holding mechanism 38 up and down is a tab value display device that displays the tab value input from the tab value setting key 40.

43 is a deformation setting key for commanding the deformed shape and deformation rate; 44
is the text on the dial.

A series setting key 45 commands the selection of the main lens for converting characters into the size of a desired series, and a series setting key 45 receives commands from the transformation setting key 43 and the series setting key 44 to drive the main lens turret 24 and the like to a predetermined position. 46 is a modified turret selection control device for setting the lens.

A series encoder 47 receives signals from the constant key 43, series setting key 44, turret selection control device 45, etc., and converts information such as the currently set series and deformed shape into a predetermined binary code. A signal from the light receiving element on the element holding mechanism 38.

FIG. 3 is a diagram for explaining the relationship between the character arrangement on the dial and the code on the code plate 35. In the figure, 23 indicates the left end of each character as shown in FIG. 35 is a code plate shown as 35 in Fig. 2, and for convenience of explanation, the code plate 35 is as shown in Fig. 2. The illustration is made so that the upper side when installed on a phototypesetting machine is the left side in the figure.

The pitch of the code on the code plate 35 in the vertical direction in the figure corresponds to the pitch in the vertical direction in the figure of the character string on the dial 23, and the position of this code in the horizontal direction in the figure is itself the position on the dial. It is designed to indicate the character width of the characters in the corresponding string.

In other words, if the left and right direction of the figure on the code board is divided like a two-dot chain line, each section is a position where a different number of EMs will appear in sequence, and now the full width is ICl3, and each section is IBM. As an example, the number of EMs in each section when divided into sections is shown numerically below the code plate 35.

(The characters on the dial 35 are divided by dotted lines into sections where characters of the same width are accommodated, and the character width calculated by the number of EMs in that section is shown on the left side of the dial 35.

)Although the example in Fig. 3 shows the case where a sub-plate is used as the dial 23, of course it can also be applied to the main plate without any problem, and as mentioned above, it can also be applied to dials of various shapes. However, it can be implemented in exactly the same way, and although the EM number is used to calculate the character width, other units such as mvt, grade, inch, etc. may be used if a conversion circuit is provided.

FIG. 4 is a diagram showing details of the holding mechanisms 37 and 38 for the light emitting element and light receiving element in FIG. 2, and their relationship with the code plate 35.

The light emitting element holding mechanism 37 holds as many light emitting elements as the number of positions indicating the EM number indicating the character width on the code plate 35 shown in FIG. 3 at the same pitch as the code interval pitch.

The light-receiving element holding mechanism holds the light-receiving elements in exactly the same manner, but the number of light-receiving elements is increased by an arbitrary amount than the number of light-emitting elements, and the output of each light-receiving element is treated as character width information output. .

Therefore, if the topmost light-receiving element represents a character width of 1716EM, the second one represents a character width of 2/16EM, and the third one represents a character width of 3/16EM.

Therefore, when using a code board as shown in Fig. 35, in order to detect the normal character width, the fourth light-receiving element from the top (
4/16EM character width) is positioned at the top of the code plate.

A rack 5 is provided at the bottom of the light-receiving element holding mechanism 38.
1 is provided and meshes with a pinion 52, and this pinion 52 is further coupled to a drive source shown at 39 in FIG.
8 can be moved up and down.

The code plate 35 is a holding mechanism 37 for the light emitting element and the light receiving element.
．． 38, and when the desired character on the dial is located at the optical axis position of the phototypesetting machine, the character width of the character can be detected.

In the device configured in this way, for example, the code plate 35
Assuming that the upper code is composed of a hole, the light receiving element holding mechanism is placed at a distance of 1/16 EM on the code plate 35 (
In the example in Figure 3, if the character is moved downward or upward by a distance equivalent to 1 pitch (in the example of Figure 3), it will be 1/16th of the normal character width.
The light from the light emitting element will reach the light receiving element that shows a value smaller or larger by EM, and as a matter of course, a character width increased or decreased by 1/16 EM from the normal character width will be transmitted to the calculation unit 48. Become.

In a phototypesetting machine configured in this way, when performing normal printing or when printing by advancing each character width using a dial as shown at 23 in Fig. 3, press the tab value setting key. From 40 onwards, specify the lens of the desired series using the series setting key 44 without inputting any information, and press the transformation setting key 4 as necessary.
After inputting the deformed shape, deformation rate, etc. from step 3, the dial is moved forward, backward, left and right to position the desired character at the optical axis position, and the character is printed on the photosensitive material on the photosensitive material drum 29 as described above.

Then, if you want to feed by the width of the body area 1 or set the feed amount using a feed amount setting key (not shown) and send that amount, the signal from the series encoder 46, the feed amount setting key, etc. is sent to the calculation section 48. Here, it is set to a predetermined feed amount and sent to the feed control circuit 49, where it is fed by a predetermined amount.

Furthermore, when the dial 23 and the code plate 35 are used to advance each character width as shown in FIG. The light-receiving elements on the mechanism 38 are each designed to detect the regular character width of the characters on the dial, and the character width encoder 47 transmits this to the calculation section 48, and the calculation section 48 converts the character width information into a series. The series information sent from the encoder 46 is multiplied and the result is sent to the feed control circuit 49.

Therefore, the feed control circuit 49 feeds the printed characters by the width of each character, and a printed product as shown in FIG. 1 is obtained.

Now, if you want to print a tab by increasing or decreasing the feed amount evenly from the character width of each character as shown in the first diagram, input the feed amount you want to decrease or increase from the tab value setting key 40. , first, the pawl value is displayed on the pawl image display device 42, and then the movement control circuit 41 for character width detection is activated by the drive source 39.
If the code plate 35 and the code detection mechanism are arranged as described above, the light-receiving element holding mechanism 38 is moved downward when the character width is desired to be reduced. .

At this time, if it is desired to reduce the character width of each character by 2716 EM, for example, the light receiving element holding mechanism 38 may be moved downward by an interval corresponding to two light emitting elements.

In this way, as described above, the holding mechanism 3 of the light receiving element
Since each of the light receiving elements on 8 corresponds to a specified number of EMs, the light passing through the code hole on the code plate 35 is divided into the light receiving element holding mechanism 38 according to the original number of EMs.
The light receiving element exhibiting a smaller number of EM is reached by the movement of the light receiving element, and the calculation of the part (M+m) in the above equation 0 is calculated by moving the mechanical light receiving element holding mechanism 38.

When the desired character is printed as described above, the character width encoder 47 sends this reduced character width information to the calculation unit 48, and the calculation unit 48 combines the series information sent from the series encoder 46 with the character width encoder 47. This character width information is multiplied, the feed of the 0 formula is calculated, and the result is sent to the feed control circuit 49 to perform the feed associated with printing, thereby obtaining a printed matter as shown in the first diagram.

By configuring the phototypesetting machine in this way, it is possible to reduce the feed amount by an equal amount from the character width of each character as shown in the first diagram, or to print by adding a feed amount equal to the character width of each character, etc. In this case, there is no need to perform any allocation calculations, and printing can proceed semi-automatically.

In addition, in the above explanation, the character arrangement on the dial was explained in which characters of the same width are arranged in horizontal rows, but if these are arranged in vertical rows, the character width detection mechanism is connected to the Y of the dial. In addition, if an appropriate conversion mechanism is provided to correlate the character spacing on this dial and the pitch between symbols on the code plate 35, it is not necessary to make them equally spaced.

Furthermore, in the above explanation, the light-receiving element holding mechanism 38 is driven by the drive source 39, but this can also be done manually by an appropriate method, or both the light-emitting element and the light-receiving element holding mechanism can be fixed. Alternatively, the number of light emitting elements and light receiving elements may be the same, and the code plate 35 may be movable.

Further, in the above description, the code plate is provided in the character frame, and the code detection mechanism is placed on the phototypesetting machine side, but the arrangement is the same even if this arrangement is reversed.

In addition, the code on this code board is set in units of 1/16 EM, and its shape is a hole, but it may also be a finer unit or a coarser unit, and the shape may be a reflective mirror surface instead of a hole. , a simple black or white mark, or a magnetic one, and the detection mechanism may be adapted accordingly.

or. Recently, typewriters and the like have appeared that use a drive source such as a pulse motor to feed the characters as they print, but it is not easy to apply the present invention to such devices. In that case, the transformation setting key 43
, series setting key 44, turret selection control 45, etc. may be replaced with a mechanism for detecting the size of the typeface.

As described above, the phototypesetting machine of the present invention has a dial 23 in which each character is offset to one end of its body area and characters are arranged in the same vertical or horizontal row with the same character width.
In phototypesetting machines and similar machines using the above, a code plate is provided with a character width code at a position corresponding to the character width for each character string, and is attached to the character frame so as to be linked with the movement of the dial 23. 35, and a detection mechanism 37 for detecting a character width code on the code board corresponding to the desired character on the dial 23 when the desired character is located at a predetermined printing position.
38, a character width encoder 47 that converts the signals from the detection mechanism 38 into predetermined feed amounts, and calculates the feed amount from the output of the character width encoder 47 and the size information of the character to be printed, and controls the feed. Based on the signals from the arithmetic unit 48 that sends the feed amount to the circuit 49 and the pawl value setting key 40, one light receiving element holding mechanism 38 constituting the detection mechanism is set relative to the other light emitting element holding mechanism 37. The present invention is characterized by comprising a circuit for causing the deflection to occur.

As a result, calculation of the tab value can be replaced with mechanical movement of the character width detection mechanism, and a complicated arithmetic circuit for calculating the feed amount is not required.

In addition, the operator can concentrate solely on typesetting without having to calculate the layout in advance, and it brings about various advantages such as being able to obtain beautiful printed matter with even character spacing.
