Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a light-shielding cassette adapter. An axis attached to the side edge in the axial direction, rotatably holding the shaft around which the rolled photosensitive material is wound Positioning of the light-shielding cassette can be performed easily and printing position accuracy can be improved. The present invention relates to a light-shielding cassette adapter.

[0002]

[Problems to be solved by conventional techniques and devices]

  It is well known to use compact cassettes in phototypers. But typesetting machine Is originally designed to use a wide photosensitive material (for example, a width of 30 cm or more) When the width of the roll-shaped photosensitive material is wide to some extent as shown in FIG. Is not a problem, but when using a roll-shaped photosensitive material with a narrow width of 3.5 cm, etc. Even a slight misalignment has a great influence on the printing position accuracy, and the edges of printed characters are cut off. It may cause damage to the commercial value of the product. Especially in roll form The photosensitive material is a relatively expensive material, and it is wasted as little as possible to be efficient. There is a request to prevent the portion from appearing, so when using a roll-shaped photosensitive material with a narrow width, The placement accuracy is extremely important.

[0003]

[Means for Solving the Problems]

  In order to solve the above problems in the prior art, the present inventor has made a simple positioning As a result of diligent examination of the adapter for the light-shielding cassette, the present invention has been completed. .   That is, the present invention rotatably holds the shaft around which the roll-shaped photosensitive material is wound, and installs it at one end. At the side edge in the axial direction of the light-shielding cassette, which has the beam opening as the outlet for the rolled photosensitive material. An attached adapter comprising a first guide and a second guide , The first guide and the second guide are tightly connected by an elastic member and by the width adjusting screw. The adapter for the light-shielding cassette is characterized in that its width is finely adjustable. It is the one that provides the data.

[0004]   Hereinafter, the light shielding cassette adapter of the present invention will be described with reference to the accompanying drawings.   The light-shielding cassette adapter of the present invention is the same as the cassette 8 shown in FIG. Can be applied. In FIG. 1, the cassette 8 is a cap type on the accommodation box body 7. Formed by fitting the side plates 4 and 4 ', but loaded in the cassette in advance. Of the side plates 4 and 4'on the winding core 2 of the roll-shaped photosensitive material 3 in which the photosensitive material 1 is wound around the winding core 2. Bite the core holding shafts 5 and 5 '(however, the core holding shaft 5 is not shown in the figure) As a result, the roll-shaped photosensitive material 3 is suspended in the cassette, and the width of the cassette is reduced. The structure is such that the photosensitive material can be pulled out from the pull-out port 6 formed in the direction.

[0005]   Next, the adapter of the present invention attached to this light shielding cassette is shown in FIG. This will be described with reference to an exploded perspective view.   The first guide comprises a side plate 9 and a spacer 11. In addition, the side plate 9 and the It is better to integrate Pacer 11 with adhesive etc. and the strength of the adapter and the ease of fine adjustment Therefore, it is preferable. Alternatively, the side plate 9 may have a width to serve as the first guide. Yes.   The side plate 9 has a plurality of holes 12A for elastic members 12 such as springs and width adjusting screws 13. Are provided with a plurality of holes 13A. The spacer 11 has a plurality of holes for the elastic member 12. 12B is provided. Furthermore, tap 13 is used for fixing the width adjustment screw 13 and for fine adjustment. B is built.   The second guide side plate 10 is provided with a plurality of holes 12C for the elastic members 12. There is.   The side plates 9 and 10 are preferably made of plastic in terms of ease of molding and strength. Good The spacer 11 is a plastic if it can be used to build the tap 13B. It may be made of stick or wood, but is preferably made of plastic. Yes.   The side plate 9, the spacer 11 and the side plate 10 have a plurality of holes 12A, 12B for the elastic member 12. And 12C to be tightly connected by the elastic member 12. The width adjusting screw 13 is a side plate 9. The side plate 10 can now be pushed through the hole 13A in the ing. The width of this fine adjustment may be about 0 to 5 mm. Also, sprinkles About four elastic members 12 such as a rubber are good, and the number of width adjusting screws 13 is not particularly limited, either. It is preferable to use 2 to 4 in consideration of practicality and balance.

[0006]   Next, how to attach the adapter of the present invention to the phototypesetting machine, see the perspective view of FIG. explain.   Insert the adapter 14 for fine width adjustment of the present invention into the cassette holding shaft 16 and then Insert the cassette 8 that holds the photosensitive drum 3 rotatably and the adapter 15 for adjusting the width And it is fixed by a movable cassette holding shaft 17.   In this state, perform exposure and development to confirm which position on the photoconductor is exposed. Therefore, the width of the width fine adjustment adapter 14 of the present invention is adjusted according to the offset width. This As described above, the position of the cassette 8 can be accurately determined.

[0007]

[Effect of device]

  According to the present invention, even when using a roll-shaped photosensitive material having a narrow width such as 3.5 cm, Accurate and accurate positioning can be performed easily by simple operation, and It is possible to prevent the border characters from being cut off.
