DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll-shaped recording medium, and is suitably applied to, for example, a heat-sensitive photographic film used in a printer.

[0002]

2. Description of the Related Art Conventionally, as a recording medium for a printer, for example, a photographic paper or a heat-sensitive photographic film is wound around a cylindrical core (hereinafter referred to as a roll core) made of paper or the like. These are widely known.

An image or the like supplied from the printer device is printed by mounting the roll-shaped printing film on a predetermined portion in the printer device.

[0004]

However, since such a printing film is hard, it is difficult to maintain it in a roll shape. For example, when the printing film is taken out of a printer and replaced with another printing film. In addition, there is a problem that the taken out printing film is unwound.

For this reason, the handling of the printing film becomes complicated, and the work efficiency of the replacement of the printing film is remarkably reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to realize a roll-shaped recording medium capable of sufficiently improving the working efficiency of a recording medium changing operation in practical use.

[0007]

According to the present invention, in order to solve the above-mentioned problems, a recording medium wound in a cylindrical shape is rotatably mounted on a roll-shaped recording medium in which the recording medium is wound in a cylindrical shape. A holding means for holding is provided.

As a result, in the roll-shaped recording medium, it is possible to prevent the recording medium wound in a cylindrical shape from being unwound.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a printing film cassette as a whole, which is constituted by a printing film portion 4 formed by winding a printing film 2 around a roll core 3 and integrally and rotatably held by a holder 5. ing.

In this case, the holder 5 is made of a material having a low coefficient of friction, such as plastic, and has a left-right symmetrical holding member 6A formed in a circular shape having substantially the same size as the winding diameter of the printing film 2 of the printing film portion 4. , 6B, and as shown in FIG.
Sleeves 7A and 7B for connecting the print film unit 4 to the holder 5 are provided in areas corresponding to the print film unit 4 on C and 6D via sleeve receiving units 8A and 8B.

At this time, the sleeves 7A and 7B are formed by using a material having a low coefficient of friction such as plastic, and the roll core 3 of the printing film portion 4 of the sleeves 7A and 7B.
The outer diameter of the part to be fitted into the roll core 3 is selected to be substantially the same as the inner diameter of the roll core 3.

Thus, in the printing film cassette 1, when the holder 5 holds the printing film portion 4 integrally, the sleeve 7 is attached to the roll core 3 of the printing film portion 4.
A and 7B are fitted, and the holder 5 can rotatably hold the printing film portion 4;
By reducing the friction between the holder 5 and the printing film portion 4, the generation of paper dust due to the friction can be avoided.

At this time, each holding member 6A of the holder 5
6B, nails 9A and 9B are respectively provided at at least three predetermined positions corresponding to the winding diameter of the printing film 2 of the printing film unit 4 so as to protrude in directions facing each other, as shown in FIGS. Is provided.

Thus, in the printing film cassette 1, after the holder 5 holds the printing film portion 4 integrally, it is necessary to prevent the printing film 2 wound around the roll core 3 of the printing film portion 4 from unwinding. It is made to be able to prevent.

Each of the pawls 9A and 9B has a corresponding one of spokes formed of a material having a low coefficient of friction such as plastic and having a length substantially equal to the length of the printing film portion 4 in the width direction. 4, a film 11 is fixed to the spoke 10 with an adhesive or the like as shown in FIG. A dust removing pad 12 made of a sponge and having a length substantially equal to the length in the width direction of the printing film 2 is fixed to an end 11A of the printing film 2 with an adhesive or the like.

At this time, the film 11 is formed by folding the leading end 11A inward with respect to the circumferential direction of each of the holding members 6A and 6B facing the holder 5.

Thus, in the printing film cassette 1, after the holder 5 integrally holds the printing film unit 4, the holding members 6A and 6B are fixedly held so as to have a corresponding positional relationship, and the printing film is held. The dust and the like adhered to the printing film 2 of the section 4 can be removed.

In the printing film cassette 1 having the above arrangement, the holding members 6A and 6B of the holder 5 opposed to each other.
By using the pawls 9A and 9B, the printing film 2 can be taken out of the printer without being unwound.

Therefore, according to the printing film cassette 1, the work of replacing the printing film 2 in the printer can be facilitated, and the work efficiency of the replacement work can be sufficiently improved for practical use.

According to the above construction, the rolled print film 2 is provided with the holder 5 having the holding members 6A and 6B for holding the print film 2 so as to sandwich the print film 2 from both sides in the longitudinal direction. By providing the claws 9A and 9B protruding in the directions opposite to each other on 6A and 6B, the printing film 2 wound around the roll core 3 of the printing film unit 4 can be prevented from being unwound.
Thus, it is possible to realize the printing film cassette 1 capable of sufficiently improving the work efficiency of the replacement work of the printing film 2 in practical use.

In the above-described embodiment, the case has been described in which the sleeves 7A and 7B are provided on the holder 5 as the holding means via the sleeve receiving portions 8A and 8B. However, the present invention is not limited to this. In other words, if the holder 5 and the printing film portion 4 are to be smoothly rotated, the roll core 3 is formed of a material having a low coefficient of friction, and the sleeves 7A and 7B and the sleeve are formed on the holder 5. The receiving portions 8A and 8B may not be provided.

Further, in the above-described embodiment, a case has been described in which plastic is used as the material of the sleeves 7A and 7B and the holder 5, but the present invention is not limited to this. If there is a sleeve 7
A variety of other materials can be used as the materials of the A, 7B and the holder 5.

Further, in the above-described embodiment, the claws 9A and 9B of the holder 5 are opposed to each other at at least three predetermined positions corresponding to the winding diameter of the printing film 2 of the printing film portion 4 of the holding members 6A and 6B. However, the present invention is not limited to this, and the shape and position of the print film 2 may be any other shape that prevents unwinding of the print film 2 in advance. Various shapes and formation positions can be applied.

Further, in the above-described embodiment, a case has been described in which the dust removing pad 12 is formed on the spoke 10 through the film 11 by using a sponge. However, the present invention is not limited to this, and As long as it removes dust adhering to the printing film 2, the material and the shape thereof may be various other materials and shapes.

[0026]

As described above, according to the present invention, the holding means for rotatably holding the cylindrically wound recording medium is provided on the rolled recording medium having the cylindrically wound recording medium. By providing the roll-shaped recording medium, it is possible to prevent the recording medium wound in a cylindrical shape from being unwound, and thus to improve the work efficiency of the exchange operation of the recording medium sufficiently for practical use. Can be realized.
