Description

[Detailed Description of the Invention] The present invention relates to a rotating disc type dial for a phototypesetting machine.

Conventional dials are constructed by adding characters, symbols, etc. (hereinafter referred to as images) to a single base material, and pasting together another transparent protection plate with no images to protect the images.

Therefore, even if you wanted to obtain a dial with just a few new images, it had to be made from scratch.

Particularly in the case of an automatic phototypesetting machine in which each character is given a fixed code, the above drawbacks are undesirable in terms of time and cost.

The present invention is based on these points, and FIG. 1 is a schematic diagram of the structure of a phototypesetting machine.

Light from a light source 1 passes through a condensing lens 2 and illuminates a dial 3.

The main lens 4 forms an image of the dial 3 onto a primary imaging plane 5.

The collimator lens 6 forms the image on a photosensitive material (hereinafter referred to as photosensitive material) 9 via a mirror 7 and a collimator lens 8.

The mirror 7 and collimator lens 8 are placed on a moving table 10 and are moved by a pinion 12 and a rack 13 fixed to the shaft of a motor 11.

Through this movement, images are printed one after another on the photosensitive material 9.

The dial 3 is rotated by a motor (not shown),
When the desired image comes within the range illuminated by the condenser lens 2, the light source is turned on and the image is photographed.

Since the number of images that come within the irradiation range is not limited to one but may be multiple, the selector 14 is installed near the dial 3 and is operated to photograph only the light beam of the necessary image.

An example of the dial face of the automatic phototypesetting machine shown in FIG. 1 is shown in FIG.

In FIG. 2, there is an ignition slit 15 at the outermost periphery that gives an ignition command to the light source, and inside it there are n image rows 16 arranged in rows.

An AD code 17 is arranged to select an arbitrary image from these image groups.

A dotted circle 18 shown in the image sequence 16 indicates the irradiation range.

Although the image is omitted in FIG. 2, it is usually applied in a negative form to a substrate such as glass.

Light from the light source passes through the image area and reaches the photosensitive material.

Such dials were made as follows.

FIG. 3 shows an example of this, in which a base material 19 constituting the dial is coated with a photosensitive emulsion 20, and this is coated with a photosensitive emulsion 20, for example, by the method described in Publication of Utility Model Publication No. 15249/1973. Give images.

After processing the emulsion film, the emulsion film was coated with resin or another transparent protective plate was attached to form the dial.

In the case of an automatic machine, each image and a code for selecting it (A-D code) must be provided together.

Therefore, even if just one character or code was incorrect on a single dial, which contained several thousand characters, the entire dial had to be recreated from scratch.

Figure 4 is an explanatory diagram of the perforation tape, in which the tape 21 is provided with two rows of holes of 6 units, of which 4 holes are surrounded by dotted lines.
Bit 22 is for operating the selector shown in FIG. 1, and can transmit only 24 commands to the selector.

The remaining 8 units 23 are for character selection and can accommodate 28 characters.

Therefore, in this example, the maximum number of characters that can be accommodated is 256 characters x 16 columns = 4096 characters.

However, not all of these characters are always used, and newspaper companies affiliated with the Japan Newspaper Association have unified the characters and their codes by using 2,304 characters as regular characters.

Figure 5 shows a part of the dial expanded, with dial 3 having slits) 15. 16 image rows 16. A-D code 17
is applied.

From such a dial, tape 21 as shown in Figure 4
The desired image is selected based on the signal commanded to the control circuit as input, but as mentioned above, the commonly used characters are legal to some extent, and there are also regional differences and usage. Characters corresponding to the purpose are stored on the dial as appropriate.

For example, in a newspaper company, in addition to the 2,304 characters mentioned above, characters needed by the newspaper company are inserted, resulting in a total of about 3,000 characters.

In this way, certain necessary characters will be referred to as a regular image, and characters that are inserted as necessary will be referred to as a specific image.

Each person can independently decide on the regular image and the specific image, and can change them freely.

When creating such a dial, since commonly used characters are known in advance, mass production is possible if only commonly used images are used.

However, the specific image differs for each user, and work cannot begin until the user specifies it.

In particular, in automatic machines, the control circuit cannot be constructed unless the relationship between letters, codes, and slits is determined, and without a dial, it is impossible to adjust the machine or study the optical system.

Furthermore, since there are a large number of kanji, characters that are not included in the created dial often become necessary.

In order to solve this problem, it is necessary to install an optical system separate from the optical system that illuminates the dial, and to add a special device that inserts the desired image into the optical system and takes the picture. This also contributed to the increase in the cost of automatic phototypesetting machines for Japanese text.

The present invention takes advantage of these points, and consists of a dial made by sandwiching a member such as a film with an image between base materials.

FIG. 6 shows an example. As shown in A, the base material 24 is provided with a common image 25 and an A-D code 26° ignition slit 27 for the common image, and a blank space for a specific image. There is section 28.

The opening is a member 29 for a specific image made using a film coated with a silver salt emulsion, and is provided with a specific image 30, an A-D code 31 for the specific image, and an ignition slit 32.

Such a member 29 is inserted into the blank part 28 of the base material 24 as shown in FIG.
The image film surfaces are placed one on top of the other at the position facing each other, and a protective base material 33 is prepared, and these are fastened from the direction of the shaft 34 with a suitable fastening tool 35 using well-known means such as a screw or a spring. If you tighten it with 36 and hold it in place, you will get a dial like this.

Also, what is shown in C is a specific image 38 different from the mouth member 39.
This is the member 40 which has been given the following features, and can be replaced with the member 29 as needed.

The dial thus formed is the specific image member 29.40.
is mounted and held coaxially with the base material 24 by the shaft fitting parts 65 and 66, so the specific image row is always located on the same circumference as the regular image row, while the specific image ignition slit 32 is located on the same circumference as the regular image row. Since it is applied to the same component, printing accuracy will not be affected even if there is a slight installation error in the circumferential direction when replacing, so it is possible to install and replace specific image components by visual inspection, making handling extremely easy. It is.

Next, an image command when a member for a specific image is replaced will be explained using FIG.

FIG. 7 is an explanatory diagram showing the input keyboard surface 41 of the automatic phototypesetting machine.

This board 41 has four shift keys 42 to 45. n character keys 46, 47 . ...48.49, removable character card 50.4 character card keys 51-5
4 is provided.

The characters stored in the character keys 46, 47°...48, 49 are regular images and are the regular images 25 of the base material 24 in FIG.
The characters contained in the character card 50 are applied to a specific image 30 of the member 29 as a specific image.

When a character group of four characters is selected by pressing a character key or a character card key, and one character is selected from the character group by pressing the shift key, a command signal corresponding to that character is issued from the keyboard.

When this is sent to an automatic phototypesetting machine either directly or via a perforated tape as shown in FIG. 4, it is compared with the detection signals of A-D codes 26 and 31, and if the two match, the desired image is selected.

The character card 55 in FIG. 8 is the keyboard surface 41 in FIG.
It is equivalent to the character card 50 attached to the card, and stores the specific image 39 applied to the specific image member 40 shown in FIG.

Therefore, the A-D code of the member 29 and the AD code of the member 40 are equivalent, so if the member 40 is replaced with the member 29 and the character card 55 is replaced with the character card 50 and attached to the keyboard surface, Character card keys 51-5
4 and shift keys 42 to 45 to specify an arbitrary image of the member 40.

Note that 56 is a hole provided to correspond to a character card key.

If members and character cards for various specific images are prepared in the same way, a large number of images can be selectively printed without changing the size of the keyboard.

FIG. 9 shows another embodiment, in which A-D for specific images is shown.
The reference numeral 57 is a commonly used image 58. AD code for common images 59.
This is applied to a base material 61 provided with ignition slits 60 for regular images.

Therefore, only the specific image 63 and the specific image ignition slit 64 are provided on the specific image member 62.

FIG. 10 shows another embodiment.

In all of the examples shown so far, the distribution of specific images and common images was considered only in the circumferential direction, but in this example, the distribution of the specific image and the regular image was considered in the radial direction of the dial.
A disk-shaped member 79 on which a specific image 78 is applied is applied to several rows of the character string of the regular image 80, and is held between base materials 81 and 82.

Further, the member 79 may be provided with a slit for a specific image along with the specific image 78.

The pin 83 is an example for defining the radial position of the base material and the member, and the pin 83 is used to define the radial position of the member 819 and the member 79 . By providing holes 84, 85, and 86 in the base material 82 and allowing the pins 83 to fit therethrough, it is possible to easily specify the position when mounting the member 79, and also to avoid misalignment during rotation. can be prevented.

Note that the present invention is not limited to what has been described above,
Various embodiments are possible.

For example, the shape, size, etc. of each member to which an image is applied may be arbitrary, and members of various sizes may be prepared, or two or more members may be held between base materials at the same time.

Moreover, they do not necessarily have to fit into the shaft of the dial as shown in FIG. 6.9.10.

Further, the material may be any material such as film or other plastic.

Further, in the above description, images have been divided into regular images and specific images, but the invention is not limited to this, and it is possible to freely decide what kind of image is applied to which member.

In addition, the method of holding the imaged part between the base materials is not only by simply tightening, but also by pasting with adhesive, aligning registration marks, and using a pin method to ensure accurate gripping. It may also be possible to perform alignment.

As described above, the dial of the phototypesetting machine according to the present invention includes a member on which some of the many images arranged on the dial are applied, and images other than those applied on the aforementioned members at predetermined locations. one base material with transparent blank areas on other parts, and the other transparent base material with no image applied thereon;
a rotating disk type, in which the member is arranged at a position corresponding to the transparent blank part of one of the base materials, and the member is arranged at a position corresponding to the transparent blank part of one of the base materials, and the member is disposed between two base materials and a tightening means for sandwiching and integrally combining one or more of the members; If the image is divided into a regular image and a specific image, and the regular image is applied to a certain base material or component, the base material (component) on which the regular image is applied can be mass-produced, so it is easier to make the dial. This is advantageous, and if various members with specific images are prepared and held and replaced as necessary, the number of characters that can be printed can be increased.
Furthermore, the input section is compact and can be processed.

In addition, the members according to the present invention can be installed and replaced by visual measurement, and are extremely easy to handle.Also, since the film surface positions of the regular image and the specific image almost match, the printing accuracy is good.

Further, it has great effects, such as being able to print a specific image without preparing a separate optical system unlike the conventional method.
