Description

[Detailed description of the invention] (Industrial field of application) This invention is a phototypesetting method for circular printing that allows characters and symbols to be printed in a circular or arcuate arrangement using a phototypesetting machine. It concerns the improvement of the machine.

(Prior art) Conventionally, this type of phototypesetting machine for circular printing is as follows:
The periphery of the circular photosensitive material is pressed and fixed using a presser on the photosensitive material loading base provided in the magazine, and this loading base rotates around the center of the photosensitive material loading base provided in the magazine. Rotation is transmitted to the main shaft of the loading base through a gear system consisting of a large number of shift gears, bevel gears, etc., and in order to absorb the bumpiness of the gear train, a similar gear system is installed on the opposite side. It is known to incorporate a shifter device for selecting the rotating direction of the loading base (for example, Japanese Patent Publication No. 39-5525) (Problem to be solved by the invention) The conventional device described above has a circular In addition to the inconvenience of having to use photosensitive material, it is necessary to incorporate many gears and shifter devices into the magazine, making its structure extremely complicated.Moreover, the display device (Braille device) uses a cylindrical drum. This method is difficult to see for circular or arcuate prints, making it unsuitable for printing.

This invention was made in view of the problems of the conventional technology, and its purpose was to eliminate the need for circular sensitive materials, and instead to use commonly used strip-shaped roll films, etc. In addition to making it easy to use, the internal structure of the magazine section is simplified, and the Braille board (display board) is shaped like a disk, making it easy to see the printed state.

(Means for Solving the Problems) In order to achieve the above object, this invention provides a circular rotating Braille board with the center as an axis, and diametrically rotates the Braille board with respect to the center of rotation by operating a handle. A braille device whose movement can be adjusted and is configured to operate while being held at a radial position of a required length, and the center of an elongated aperture formed along the optical axis direction on the frame side in connection with the adjustment of the position of the braille device. a movable lens system moving table that moves further to the right or left and is adjusted and set at a position corresponding to the radial length of the braille device; and a magazine body that rotates in correspondence with the rotary Braille plate around the center point of the elongated aperture, and prints characters, etc. taken from the dial onto the photosensitive material through the lens system and the elongated aperture. In each case, a magazine body consisting of a photosensitive material supply magazine and a take-up magazine and a Braille plate are angularly fed in relation to each other to obtain circular or arcuate array printing.

(Function) The Braille board in this invention consists of a circular rotating board, and the position of the Braille device can be adjusted as desired in advance to write Braille on the Braille board. Braille in the same arrangement as the arc-shaped arrangement is displayed. In addition, since the magazine body is angularly fed around the center point of the elongated aperture, there is no need for a specially shaped one; a general photosensitive material supply magazine and the same take-up magazine will suffice, and the handle can be operated from the outside. The position of the braille device and the position of the optical axis relative to the elongated aperture are thus adjusted simultaneously and in conjunction.

(Example) To explain the drawings below, 1 is a frame of a phototypesetting machine. 2 is a light source. 3 is a reflective mirror. 4 is a condenser lens. 5 is a dial for phototypesetting. 6 is a photographic tube for dial 5. 7 is a magnification conversion lens like a turret type. 8 is a reflective mirror, and a front viewfinder 9
It is inserted into the phototypesetting optical axis when copying characters. 10
is a shutter in which the light exposed through the shutter 10 passes through a deformable lens 11, changes its course by a mirror 12, passes through a collimating lens 13, passes through a lens 14 and a mirror 15, and prints on the surface of a photosensitive material 16. The above is what is known in ordinary phototypesetting machines.

As shown in FIGS. 1 to 4, the device according to this invention is provided with a rotating Braille plate 18 centered on a shaft 17 as shown in FIG. A column 20 equipped with a braille device 19 for Braille is provided, and a scale 21 is displayed on the front of this column 20, and the braille device 19 is adjusted and moved in the diametrical direction of the rotating Braille plate 18 by a mechanism to be described later. At this time, the indicator arrow 22 provided on the proximal support portion of the braille device 19 moves up and down along the scale 21 with the braille device 19, so that the indicator arrow 22 points to the scale 2.
1 makes it clear how far the braille tip 23 of the braille device 19 is held from the center of rotation of the rotary braille plate 18 (the axis of the shaft 17).

In order to raise and lower the Braille device 19 and determine its position, a handle shaft 25 having a scale handle 24 externally is provided on the frame 1, and a gear 26 provided on the handle shaft 25 is inserted vertically into the support column 20. When the operator turns the scale handle 24 in the forward or reverse direction, the gear 30 of the short shaft 29 is engaged with the rack 27 fixed to the proximal end of the braille device 19 which is slidably fitted and the pinion 28 is always engaged. By interlocking the gears 26 and 30, the pinion 28 is rotated according to the scale handle 24, and in meshing relationship with the rack 27, the braille device 19 is moved upward or downward along the column 20 and adjusted to the desired position. It is designed so that it can be set as follows.

Further, as shown in FIG. 1, the lens 14 facing the already mentioned collimating lens 13 is mounted on a lens system moving table 31 in combination with a mirror 15, and this lens system moving table 31 is attached to a guide mounted on the frame 1. A rack 33 is fixed to the moving table 31 along the optical axis, and a shaft 35 of a gear 34 that meshes with the rack 33 is connected to the handle shaft. 2

8 (FIG. 3), and when the scale handle 24 is rotated to adjust the braille device 19 up and down as described above, the lens moving stage 31 also moves laterally to the right or left along the guide bed 32,
It is set at a position related to the movement position of the Braille device 19. Reference numeral 39 is a holding roller for the rack 33 (Fig. 1).The lens system moving table 31 moves laterally in the optical axis direction together with the lens 14 and mirror 15, so it is placed on the frame 1 side. forms an elongated aperture 40 in the optical axis direction having a length corresponding to the displacement. This elongated photographic aperture 40 is constructed by fixing a cylindrical base plate 41 to the upper part of the frame 1 in view of the optical path length for image formation of the lens 14 and other mechanical points. An elongated aperture 40 is formed.

The photosensitive material 16 (film, etc.) is in contact with the upper surface of this elongated copying aperture 40, and the photosensitive material 16 (film, etc.) is in contact with the upper surface of this elongated copying aperture 40, and is connected to the above-mentioned rotating braille plate 18 with the center of the elongated copying aperture as the axis. The photosensitive material 16 is rotated by an angle (input amount), and therefore, a roll-shaped photosensitive material 16 is used, and it is configured to be fed out from a supply magazine 42 and stored in a take-up magazine 43. These magazines 42, 43 are shown in FIGS. 1, 3 and 5.
As shown in FIG. 6, the cylindrical base plates 41 are arranged oppositely so as to be held in the diametrical direction and are integrally combined to form a magazine body, and the bottom part and the upper surface of the cylindrical base plate 41 relative to the magazine body are formed. Annular grooves 44 and 45 are formed around the axis of the cylindrical portion of the base plate 41, and a ball 46 is housed in the groove so that the ball 46 can be smoothly rotated with respect to the cylindrical base plate 41 together with the photosensitive material. Make it. Further, a cutter for the photosensitive material is provided near the entrance of the winding magazine 43, and when a certain amount of the printed photosensitive material 16 is stored in the winding magazine 43, the push button 47 is pressed and the cutter cuts the photosensitive material 16. The camera is configured to cut and process photos.

In order to rotate the rotary Braille plate 18 and the magazine body in relation to each other, a pulse motor 48 is provided on the frame 1 as a power source, and gears 49, 50 are connected to the shaft from the shaft as shown in FIG. ,5
1 to drive a horizontal shaft 52, and a bevel gear 53 provided on this horizontal shaft 52 is connected to a mating bevel gear 54.
A worm 56 is fixed to the worm shaft 55 as shown in FIG. The rotation of the worm 56 causes the rotary Braille plate 18 to rotate in the positive direction according to the rotation direction of the pulse motor 48.
As shown in FIG. 3, a worm 58 is directly attached to the top, and teeth 60 that mesh with the worm 58 are carved on the circumference of a magazine body 59 that supports both the magazines 42 and 43 in combination. In combination, of course, this is also a pulse motor 48
A magazine body 5 that integrally supports the supply magazine 42 and the take-up magazine 43 in accordance with the rotational direction of the magazine body 5.
9 is configured to rotate in the positive direction or in the negative direction similarly to the rotating Braille plate 18.

Figure 7 to Figure 12 are examples of the outline of the main parts of the above device and its printing situation. When using this device, characters are printed radially toward the surroundings as shown in Figure 9. Or, on the contrary, it is also possible to print in a centripetal manner with the characters facing the center as shown in Figure 12 (the figure shows an example of European characters, but the characters can be printed in kana, kanji, etc.). (Of course, there is no problem with adding symbols, etc.) Therefore, first, let us explain the operation in the case of radial printing shown in Fig. 9. After determining the radius of the circular printing based on the original, the operator first Turn the scale handle 24 to move the Braille device 19 and align the indicator arrow 22 with the scale 21. Then, the pointing arrow 22 and the Braille device 19 move up and down in unison, so the Braille tip 23 of the Braille device 19 is set at the position of the circular Braille string desired by the operator, that is, the radius value determined from the center of rotation of the rotating Braille plate 18. (shown by the solid line in FIG. 7) In conjunction with this, rotation of the scale handle 24 causes the gear 34 to shift to the rack 33.
is sent toward the tip, so the lens system moving table 31 moves along the guide bed 32 and moves along the aperture 40 by the radius value determined from the center of the elongated aperture 40 for emitting character images onto the photosensitive material 16. The movable lens system and the Braille device 19 are now set in relation to each other.

Next, set the feed amount using a digital switch (not shown) to set the amount of character filling when typesetting the size of the characters or inserting a deformed lens. Type the necessary characters from the screen and press the phototypesetting key to print. When one character is printed on the photosensitive material 16 in this way, the pulse motor 48 rotates, so the horizontal shaft 52 rotates, and the rotating Braille plate 18 is moved by a certain angle in the counterclockwise direction indicated by the arrow a in FIG. At the same time as turning, the worm 58 on the coaxial 52
Then, the magazine body 59 is rotated about the center of the elongated copying hole 40 by the amount of character feed, and is ready to print the next character.

Also, unlike the case shown in Fig. 9, when printing in a circle with the character string facing the center as shown in Fig. 12, the operator first turns the scale handle 24 in the opposite direction to the above case. Then, as shown by the dotted line in FIG. 7, the position of the braille device 19 is determined by lowering it to the determined radius value. In connection with this, the movable lens is displaced to the left from the center of the elongated aperture 40, and is set as shown in FIG. If the rotating Braille plate 18 and the magazine body 59 are switched in the opposite direction to the above case, the rotating Braille plate 18 and the magazine body 59 are
2 Rotate in the opposite direction to arrow a as shown by arrow b in Figure 2,
A circular array of characters toward the center is obtained, as illustrated in FIG.

In any case, once you have finished printing the desired circular array, turn the magazine handle to remove the photosensitive material 16.
After winding the photosensitive material 16 into the take-up magazine 43, press the push button 47 to cut the photosensitive material 16 with a cutter.
The take-up magazine is taken into a darkroom for photographic processing.

(Effect of the invention) This invention has the circular rotating Braille board 18 as described above.
By using the Braille device 19, it is possible to write Braille characters of the same size as the actual circular or arc-shaped character arrangement on the Braille board surface for each printing, so the display is extremely easy to see, and the position of the Braille device 19 can be easily determined. handle 24
When adjustment is made, the lens system moving stage 31 also moves in conjunction with this, making handling extremely simple.Moreover, there is no need to use a specially shaped photosensitive material 16, and a material for general typesetting can be used. This has the effect of producing a circular arrangement of typesetting.
