Abstract

(57) [Summary] (Correction) [Purpose] To provide a roll-shaped photosensitive material cassette in which the photosensitive material outlet can always be formed in the same shape. In the roll-shaped photosensitive material cassette in which the slit-shaped outlet 11 is formed in the width direction of the material 1, a part of the folding surface adjacent to the final end folding surfaces 9 and 10 of the body member 6 folded inside is folded. A cassette for a roll-shaped photosensitive material, characterized in that the cassette is fixed in contact with the inner surface of the body member 6 at a non-existing portion.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cassette for holding a roll-shaped photosensitive material.

[0002]

[Prior art]

 The roll-shaped photosensitive material cassettes used in a typesetting machine include a metal cassette installed in the typesetting machine, a disposable cassette in which a body member is made of cardboard sheet, paperboard and the like, and a side plate is made of plastic.

The present invention relates to the latter cassette. Conventionally, the structure of the outlet in this type of cassette is shown in FIGS. FIG. 3 is a partially disassembled perspective view of the cassette. FIG. 4 is a side sectional view of a conventional slit-shaped outlet portion. FIG. 5 shows an inverted perspective view of the upper part of a conventional slit-shaped outlet.

The cassette is formed by fitting the plastic cap type side plates 4 and 4 ′ into the body member 6 made of paper. The photosensitive material 1 previously loaded in the cassette is wound around the core 2. The core 2 of the roll of photosensitive material is covered with the core holding shafts 5 and 5'of the side plates 4 and 4 '(however, the holding shaft 5'of the side plate 4'is not shown in the figure). As a result, the roll of photosensitive material is suspended in the cassette, and the photosensitive material can be drawn out from the outlet 11 formed in the width direction of the cassette. In the conventional cassette example shown in FIG. 4, one end of the body member is folded two or more times at the upper or lower part of the outlet, and the upper final end folding surface 9 or the lower final end folding surface 10 of the folded body member is formed. It was fixed to the inner surface of the body member with an adhesive or the like.

As this fixing method, a slit-shaped outlet is formed on the inner surface of the body member 6 so that the gap of the outlet 11 of the cassette is uniform over the entire contact surface of the roll-shaped photosensitive material. A ruled line 14 having a width of about 0.1 to 0.5 mm is put in the widthwise direction of the rolled photosensitive material, and the upper end final folding surface 9 or the lowermost final folding surface 10 of the outlet is aligned and fixed to the ruled line.

However, when a stable and stable outlet is formed in the fixing method, the upper final end folding surface 9 or the lower final end may be formed depending on the operator's feeling, experience, or environment such as working environment. It is difficult to accurately align the end folding surface 10 with the ruled line 14 on the inner surface of the body member 6 as a guide.

If this alignment is poor, a force is applied in the direction (arrow A) in which the upper folding surface 7 ′ and the lower folding surface 8 ′ come close to each other, and the pressing force against the photosensitive material passing through the drawing port is strong. Become. As a result, the pull-out force of the photosensitive material becomes large, and the upper folding surface 7'or the lower folding surface 8'and the photosensitive material 1 are strongly scratched, which is a problem in terms of quality.

On the contrary, if the upper folding surface and the lower folding surface are in the direction in which they separate from each other (arrow B), the size of the gap between the outlets becomes large and light leakage occurs, which is fatal for the photosensitive material. There is also the problem of light beam fog.

[Problems to be solved by the device]

 An object of the present invention is to provide a roll-shaped photosensitive material cassette in which the photosensitive material outlet can always be formed in the same shape.

[0010]

[Means for Solving the Problems]

 The above object of the present invention is to provide a roll-shaped photosensitive material cassette in which at least one end of the body member is folded inside to form a slit-shaped outlet in the width direction of the roll-shaped photosensitive material. The roll-shaped photosensitive material cassette is characterized in that a part of the folding surface adjacent to the final end folding surface is fixed in contact with the inner surface of the body member in the unfolded portion. One mode of the present invention will be described by way of example, but the present invention is not limited to this.

[0011]

【Example】

 A roll-shaped photosensitive material cassette according to the present invention will be described with reference to the drawings. FIG. 1 is a side sectional view of an outlet in the cassette of the present invention. FIG. 2 is an inverted perspective view of an upper portion of the outlet and a perspective view of a lower portion of the outlet in the cassette of the present invention. FIG. 3 is a partially disassembled perspective view of the cassette of the present invention.

According to the present invention, the folding surface 7 adjacent to the upper end edge folding surface and the folding surface 8 adjacent to the lower final edge folding surface each have a widthwise 1/3 part from the left and right ends of the body member 6 in the width direction. Centering on, the crease line 13 of the upper end edge folding surface 9 and the crease line 13 ′ of the lower end edge folding surface 10 to the upper fold surface 7 and the lower fold surface 8 are provided with rectangular notches 12, The notch 12 is folded in the direction opposite to the folding direction of the upper final end folding surface 9 and the lower final end folding surface 10. Regarding the folding length, since the tip of the notch portion 12 is set so as to vertically hit the body member front surface portion 15 and the lower folding surface 8 ′, the upper folding surface 7 ′ or the lower folding surface 8 of the outlet is set. The length is good in consideration of the fact that the photosensitive material can always be kept in surface contact.

The upper final end folding surface 9, the lower final end folding surface 10 and the notch 12 provided on the folding surface adjacent to the final end folding surface are fixed to the inner surface of the body member 6 with an adhesive. . Further, the roll 3 of photosensitive material is housed inside the body member, and the side plates 4, 4'are joined together to complete the roll-shaped photosensitive material cassette of the present invention.
