Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magazine in which a long strip of photosensitive material is wound and stored in a roll for use in a phototypesetting machine.

As shown in Fig. 7, the conventional magazine of this type is made up of a drum a wrapped with a single sheet-like photosensitive material, which is rotatably disposed inside the drum a, so that it can be used as a photosensitive material for typesetting. Since the objects are of fixed size, it is necessary to remove the magazine b from the machine stand c and replace the photosensitive material every time one page is typesetting, for example, resulting in poor work efficiency.

In order to eliminate this problem, a magazine has been devised in which a long photosensitive material wound in a roll is stored inside the magazine body, and the photosensitive material can be pulled out upward by wrapping it around an imaging roller. However, since the photosensitive material wound into a roll is handled as is, there is a risk of not only staining but also exposure to light, and furthermore, the photosensitive material wrapped around the imaging roller is curved along the roller. This makes it difficult to phototype with high precision, and there is also the problem that a separate mechanism must be provided to cut the photosensitive material into a predetermined length.

The present invention solves these problems,
A photosensitive material wound into a roll is retractably stored in a storage case body, and the case body is removably disposed within a magazine body, and the photosensitive material is stretched in a direction perpendicular to the photographic aperture. Furthermore, a photosensitive material cutting mechanism is disposed within the magazine body, and a photosensitive material collection case body can be detachably attached to the magazine body.
In addition, when printing in the length direction on a photosensitive material, a roll in a phototypesetting machine is used that allows smooth phototypesetting by temporarily accumulating slack that occurs when the photosensitive material is fed backwards in the lower space of the magazine body. The present invention provides a magazine for shaped photosensitive materials.

Further, the inlet port 36 of the photosensitive material recovery case 35 is inserted into the photosensitive material outlet hole 31 of the magazine body 1, and the lever 49 is operated to move the light shielding plate 44 downward, thereby opening the photographic aperture 2.

In this state, select a desired character from the dial on which the alphabets are lined up as is known, turn the shutter in line with the aperture, and move the image of the alphabet using the light from the light source via the refracting mirror 15 of the lens system 14. , a predetermined portion of the photosensitive material 9 stretched between the rubber rolls 11 and 12 and the guide roll 13 is printed.

In this way, each time a character is printed on the photoreceptor 9, the pulse motor drive gear 43 is operated to rotate the rubber roll 11 from the rotation transmission gear 42 via the intermediate gear 41, and the photoreceptor 9 is drawn out from the case body 7 while being placed at a predetermined pitch. address, and move it upward in sequence. Further, when printing in the horizontal direction (width direction) on the photosensitive material 9, printing is performed while moving the horizontally moving lens system 14 without operating the pulse motor drive gear 43.

Further, when the rubber rolls 11 and 12 are rotated in the opposite direction to the rotational direction to change the printing line after vertical printing is performed on a predetermined length of the photosensitive material 9, the photosensitive material 9 is exposed to light through the guide roll 13. The object 9 is allowed to sag in the lower space 8 of the case body 7 in a curved state as shown by the dotted line, and is once accumulated therein, and is sent upward again while printing by vertical feeding, and is collected through the photoreceptor outlet hole 31. It is stored in the case 35 along the guide 38.

When the typesetting for a predetermined length of the photosensitive material 9 is completed in this way, the photosensitive material 9 is sent upward by an appropriate length to position the lower end of the length at a suitable position on the blade of the fixed cutter base 23, and then the cable 29 , 30 to move the cutter holder 18 from one small chamber 24 side to the other small chamber 25 side, the holder 1

Next, the collection case 35 is removed from the photosensitive material outlet hole 31 of the magazine body 1 and moved to the fixing work section, while a new empty collection case is again attached to the photosensitive material outlet hole 31 of the magazine body 1, and the roll is removed. The above-mentioned typesetting operation is performed while pulling out the photosensitive material 9, which has been rolled up into layers, for a predetermined length.

As described above, the present invention is configured such that the photosensitive material wound into a roll is stored in the storage case body 7, and the case body 7 is detachably disposed within the magazine body 1. The photosensitive material can be easily handled without being contaminated or exposed to light, and phototypesetting can be performed while pulling out the photosensitive material by the required length from the case body 7 inside the magazine body 1. A pair of photosensitive material delivery rolls 11 and 12 and a guide roll 13 are provided.
The photosensitive surface of the photosensitive surface can be accurately opposed to the photographic aperture by being stretched between the photographic apertures, thereby allowing highly accurate photosetting. Furthermore, when performing continuous printing on a photosensitive material in the length direction, the storage case body 7 prevents the sagging of the photosensitive material that occurs during reverse feeding when changing lines.
The paper can be accumulated in the space 8 between the magazine body 1 and the inner bottom surface of the magazine body 1, and it can be fed in the drawing direction again to enable smooth phototypesetting.

Further, the pair of photosensitive material delivery rolls 11,1
A horizontally fixed cutter stand 23 is placed in the magazine body 1 adjacent to the upper part of the cutter stand 2, and a round cutter 22 is moved by an operation from outside the magazine body 1 while slidingly contacting the cutting edge of the cutter stand 23 to cut the photosensitive material.
As a result, a photosensitive material with phototypesetting applied to a desired length can be immediately cut within the magazine body 1 without being affected by light at all, and the cut photosensitive material can be cut into the magazine body 1. 1 can be automatically stored in a collection case 35 that is detachably attached to the container 1, thereby improving work efficiency.
