BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette or magazine for holding roll-shaped materials (hereinafter referred to as "magazine").

[0002]

2. Description of the Related Art As a relatively wide roll-shaped photosensitive material magazine 1 conventionally used for printing, printing, copying, etc., as shown in FIGS. 1 and 2, for example, a cylinder made of cardboard or plastic is used. A short cylindrical body portion 3 formed by bending a plate, and two side plates 4 and 4 for sealing both ends of the body portion 3.
A roll-shaped photosensitive material 9 wound around a core 5 pivotally supported on the inner surfaces of the side plates 4 and 4 is accommodated in a hollow interior made of light-shielding material. There is known a magazine for photosensitive material which draws out the photosensitive material 9 from a slot 10 provided with a light-shielding means extending in the axial direction of No. 5 (for example, see Japanese Patent Publication No. 59-36736). The two side plates 4 and 4 for sealing both ends of the body part 3 are structurally provided with grooves for engaging with the edge of the body part 3 and keeping light shielding, a rotary bearing of a photosensitive material core 5 housed in a magazine, and the like. Since it has a relatively complicated uneven shape and requires the required rigidity and precise dimensions, plastic molded products are usually used. A slot 10 is provided at a corner of one surface of the body portion 3 and extends in the entire axial direction of the body portion 3.
Is composed of a portion corresponding to the upper lip, a lower lip connected to one surface of the body portion 3, and light-shielding means such as telempe 11 provided on each lip surface. Further, the photosensitive material 9 is initially stored with the tip of the photosensitive material 9 pulled out from the slot 10 of the magazine, and the tip of the photosensitive material 9 is placed on the body portion 3 of the magazine, for example, with a tape so that it does not rewind into the magazine. Stopped at 2, storage, transportation, etc. are performed. For example, when the magazine is filled in the magazine mounting portion of the image forming apparatus, the tape 2 is peeled off, and the leading end of the photosensitive material 9 is gripped by, for example, a transport nip roller of the image forming apparatus, so that the roll-shaped photosensitive material 9 is removed. Is withdrawn.

[0003]

However, in the above-mentioned conventional magazine for photosensitive material, the roll-shaped photosensitive material contained in the magazine causes the winding to be loosened due to vibration during transportation, and furthermore, the photosensitive material due to vibration during transportation. However, there has been a problem that scratches are caused by rubbing the inner wall of the magazine or rubbing the photosensitive materials with each other. Further, when the photosensitive material is pulled out of the magazine, the photosensitive materials may be rubbed against each other even by tightening the winding of the photosensitive material, thereby causing damage such as impairing the quality of an obtained image. In addition, transport failure due to such loosening of the photosensitive material,
Troubles such as breaks, wrinkles, and clogging due to the meandering protrusion may occur, and defects such as misaligned ruled lines of printed matter may occur. As measures for preventing such various adverse effects, as disclosed in JP-A-2-277046,
A method of connecting the upper winding end of the roll-shaped material and the guide wrapping band with a pressure-sensitive adhesive tape and simultaneously adhering the upper winding portion of the roll-shaped material, as shown in JP-A-2-280147.
A method has been proposed in which a double-sided pressure-sensitive adhesive piece is interposed between the uppermost winding portion and the upper winding portion of a roll-shaped material and bonded to prevent rotation of the roll before the first use of the cassette. However,
In these methods, the adhesive strip passes through the slit portion of the magazine at the first use and damages the telem provided as a light shielding means in the slit portion, causing insufficient light shielding, or the adhesive adheres to the telem and adheres to the remaining photosensitive material. New adverse effects such as chemical or physical harm were observed. Accordingly, an object of the present invention is to solve the above problems, prevent the roll-shaped material from being loosened, cause no damage to the roll-shaped material before use, and cause adverse effects such as poor conveyance and defective printed matter. An object of the present invention is to provide a magazine for roll-shaped materials that does not need to be performed.

[0004]

SUMMARY OF THE INVENTION The object of the present invention is to provide a hollow core having a cylindrical body portion and side plates sealing both ends of the body portion, which is wound around a core supported on the inner surface of the side plate. In a roll material magazine for accommodating a roll material and pulling the roll material out of a cylindrical body from a slot extending in parallel with the core wire of the body portion, a part of the top of the roll material in the direction of the outlet is provided. To form an opening by forming a tongue piece by forming a notch left uncut, and folding the tongue piece toward the back side of the uppermost winding portion of the roll-shaped material so as to cover the opening and the periphery of the opening. This is achieved by a magazine for roll-shaped material, wherein the uppermost wound portion of the roll-shaped material and the surface of the upper wound portion in contact with the uppermost wound portion are adhered and fixed by applying an adhesive tape.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; The main body of the magazine for a roll-shaped material according to the present invention is essentially the same as that of the prior art described with reference to FIGS. It is characterized by providing a prevention means. That is, in the present invention, as shown in FIGS. 3 and 4, a notch in which a part of the roll-shaped material 9 is cut off in the direction of the outlet is provided in the uppermost winding portion 9 a to form the tongue piece 12.
The opening 13 is formed by folding the tongue piece 12 toward the back surface A of the uppermost winding portion 9a of the roll-shaped material. next,
As shown in FIG. 5, an adhesive tape 6 is applied so as to cover the opening 13 formed around the uppermost winding portion 9a of the roll-shaped material and the periphery of the opening. The upper winding portion surface 9b in contact with the portion is adhesively fixed.

That is, with this structure, the adhesive surface B of the adhesive tape 6 is bonded and fixed to the uppermost winding portion 9a of the roll-shaped material and the upper winding surface 9b in contact with the uppermost winding portion. The loosening of the winding is reliably prevented. The adhesiveness of the adhesive tape 6 required to prevent the roll-shaped material 9 from loosening depends on the roll diameter and the roll width of the roll-shaped material 9, the play inside the magazine body, the play between the bearing and the core, that is, the roll to be manufactured. The adhesive strength of the adhesive surface B, the size of the opening 13 (opening area), the number of openings to be formed, and the like, which are factors that determine the adhesiveness of the single-sided adhesive tape 6, are different depending on the product specifications of the magazine for shaped materials. It may be set arbitrarily according to each product specification. In the present embodiment, the shape of the tongue piece is semicircular, but the shape is not limited to this, and may be any shape such as a polygon such as a triangle or a quadrangle. 9 can be formed into any shape as long as it can be formed toward the back surface A side of the uppermost winding portion 9a so as to form an opening 13 large enough to prevent winding loosening. From the point of view, it is better to have a simple shape. Next, an example of use of the roll-shaped material magazine of this embodiment having the above-described configuration will be described. First, the roll material magazine before the roll material 9 is pulled out from the slot 10 is, as shown in FIG. 6 (a), the uppermost winding portion 9a of the roll material 9 is upper wound by the adhesive surface B of the adhesive tape 6. Adhesively fixed to the outer surface 9b,
The roll-shaped material is prevented from loosening. Next, when the roll material 9 is pulled out from the slot 10 of the roll material magazine, as shown in FIG. 6B, the adhesive surface B of the adhesive tape 6 is peeled from the upper winding surface 9b, The function of preventing the winding looseness of the material 9 is released. In addition, since the release of the winding loosening prevention means at the time of the first use is usually performed manually, the release force is preferably set to 3 kg or less, and the adhesive strength of the adhesive surface B may be set according to this. . When the roll material 9 is further pulled out, a part of the adhesive surface B of the adhesive tape 6 becomes as shown in FIG.
The tongue piece 12 that has passed through the slot 10 and the telem 11 from the uppermost winding portion 9a of the roll-shaped material 9 toward the back surface A side of the uppermost winding portion,
In this case, the adhesive tape 6 is pushed back at the edge of the roll 0 and is folded back, thereby closing a part of the adhesive surface B of the adhesive tape 6 that has been peeled off from the upper winding surface 9b of the roll-shaped material 9, whereby a part of the adhesive surface B is removed. , Slot 10 and telem 11 can be prevented from directly contacting. Therefore, the conventional unwinding prevention, such as the failure of light shielding due to damage to the telem by the adhesive of the single-sided adhesive tape 6 and the adhesion of the adhesive to the telem and chemically or physically harming the remaining photosensitive material. Various adverse effects seen in a photosensitive material magazine provided with the means can be prevented. When the roll-shaped material 9 is further pulled out, a part of the adhesive surface B of the adhesive tape 6 finally becomes as shown in FIG.
It is pulled out of the magazine main body 1 as shown in FIG.

[0007]

As described above, the magazine for a roll-shaped material of the present invention employs the above-described structure, so that the winding of the roll-shaped material can be surely prevented from being loosened, and the roll-shaped material is prevented from being vibrated or rotated during transportation. It is possible to prevent troubles such as loose winding, poor conveyance due to loose winding of the roll-shaped material, breakage, wrinkles, clogging, and the like due to meandering protrusions, and troubles such as misalignment of printed lines. Further, when the roll-shaped material is pulled out from the slot, the above-described winding loosening prevention function is easily released, and the tongue piece folded toward the rear surface side of the outermost peripheral surface of the roll-shaped material is pushed by the edge of the slot. Since it is folded back, a part of the adhesive surface peeled off from the outer peripheral surface of the roll-shaped material facing the back surface of the outermost peripheral surface of the roll-shaped material of the single-sided adhesive tape will be closed by this tongue piece, Direct contact of a part of the adhesive surface with a slot or the like is prevented. Therefore, the conventional unwinding prevention, such as a failure of light shielding due to damage to the telem by the adhesive of the single-sided adhesive tape 6 and a chemical or physical harm to the remaining photosensitive material due to the adhesive adhering to the telem, can be provided. Various adverse effects seen in a photosensitive material magazine provided with the means can be prevented.
