BACKGROUND OF THE INVENTION
The present invention, for example, relates to an optical plate-making stamp creation equipment, more particularly, to a technique for removing dust and dirt adhering to the transparent original film as a recording medium in the transport device portion.
[0002]
[Prior art]
For example, in the stamping device disclosed in Japanese Patent Laid-Open No. 6-278350, the thermal transfer ribbon ink is transferred to a printing tape by a thermal head, and the negative film formed thereby is formed by an ultraviolet irradiation light source and a printing surface by a transport device. The ultraviolet curable resin constituting the printing surface forming member is partially cured so as to correspond to the transparent portion of the negative film by being conveyed between the members and irradiating with ultraviolet rays in that state, and then the printing surface forming member Discloses a technique for producing a stamp by removing an uncured portion of a material by washing it in a predetermined liquid.
[0003]
[Problems to be solved by the invention]
In this case, if foreign matter such as dust or dust adheres to the printing tape and is transported as it is, the ink will not be transferred by the head to the foreign material adhesion portion, leading to printing failure, or due to foreign matter during UV irradiation. The ultraviolet rays are shielded, and the portion is not cured but removed during cleaning and chipped, and a predetermined stamp face cannot be formed.
[0004]
In order to eliminate the above inconvenience, it is desirable that no foreign matter adheres to the printing tape, but this is difficult, and how to remove the foreign matter attached to the printing tape before it is transported to the head. Is a real problem. Therefore, it is conceivable to provide a dedicated mechanism for removing foreign substances adhering to the tape, as shown in Japanese Utility Model Publication No. 4-566. However, this is difficult to adopt in existing models, so further improvements are possible. There is room for. An object of the present invention is to provide a photoengraving stamp making apparatus which can be employed with little modification of the main body of the apparatus so that a mechanism capable of effectively removing foreign matter adhering to the printing tape can be incorporated in the conveying apparatus to the head of the printing tape. The point is to provide .

A pair of first separation claws and a pair of second separation claws that act on both ends in the width direction of the recording surface of the original film, and the first separation claws Provided upstream of the document film feed direction The second separation claw is provided downstream of the supply rotating body in the feeding direction of the original film, and the pair of first separation claws are hooked on both end portions in the width direction of the original film, The pair of second separation claws are hooked on both corners on the leading end side of the document film in the feeding direction, and the second frame is swung in a direction away from the supply rotating body, thereby by first separating claw and the second separation pawl, the original film is forced separated from the slightly adhesive surface, further, the width of the slightly adhesive surface, widely than the width of the recording area in the original film, and, set to the narrow casting than the width of the original film, said first separating pawl and the second separation pawl, forcing the original film by acting on a portion other than the recording area in the original film from the microporous adhesive surface octopus to separate The features.
[0006]
According to photoengraving stamp creation equipment according to claim 1 having the above structure, since the outer peripheral surface of the supply rotary member which rotates in contact with the original film was slightly adhesive surface, the head side of the original film, such as a print tape Foreign matter such as dust and dust attached to the sticker adheres to and adheres to the outer peripheral surface of the supply rotating body and is removed from the original film. Therefore, as described above, printing defects due to attached foreign matter, printing surface formation defects, and the like can be eliminated, and intended regular printing and stamp printing can be performed.
[0007]
Since the supply rotator is originally provided in the transfer device to the head, it can be used for existing models, such as replacing the supply rotator, and it is also necessary to provide a dedicated foreign matter removal mechanism. Absent. In addition, since the means for adhering foreign matter is a “fine” adhesive surface, the original film is strongly adhered to the surface of the supply rotating body and the conveyance resistance is not greatly increased. The foreign matter can be removed well.
[0008]
In addition, since the width of the slightly adhesive surface on the outer periphery of the supply rotator is made wider than the width of the recording area in the original film, even if the original film to be conveyed is slightly shifted in the direction perpendicular to the conveying direction, The foreign matter removing action is surely exhibited, and the above action according to claim 1 can be obtained with certainty.
[0009]
In addition, the pair of first separating claws are hooked on both ends of the original film in the width direction, and the pair of second separating claws are hooked on both corners on the leading end side of the original film in the feeding direction. The original film can be satisfactorily separated from the slightly adhesive surface by the four first and second separation claws.
[0010]

[0015]
Further, according to the optical plate-making stamp creation equipment of the above configuration, the width of the slightly adhesive surface, larger than the width of the recording area in the original film, and, as well as set narrower than the width of the original film, the original Since there is a recording medium separating means that acts on the film other than the recording area and forcibly separates the original film from the slightly adhesive surface, the original film is prevented from being wound around the supply rotating body by the adhesive force. A good transport state can be maintained, and the operating location is outside the recording area, so that the recording operation is not hindered by the recording medium separating means.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings for a stamp producing apparatus and a recording medium conveying apparatus used therefor.
[0017]
First, the schematic configuration and operation of the stamp creating apparatus 1 will be described. As shown in FIG. 1, 2 is a cassette-type film magazine (an example of a recording medium storage unit) provided with a transparent document film 8, and 3 is a supply port (recording medium insertion port) for a cut sheet CS for a headline label 1), 9 is a thermal transfer type ink ribbon, 4 is a printing unit (an example of a recording unit) provided with a thermal head 5 that performs printing operation, and 6 is a stamp surface formed on a stamp body 7 based on a printed original film 8. This is the stamp part.
[0018]
This stamp producing apparatus 1 is connected to a personal computer (not shown), thereby printing an original on the original film 8, printing a header label on the cut sheet CS, and the original film 8 according to control from the personal computer. Various operations such as stamp making are performed.
[0019]
That is, the original film 8 is conveyed by a tape conveying apparatus A which is a recording medium conveying apparatus, predetermined characters, figures, etc. are printed by the thermal head 5 in the printing unit 4, and the printed original film 8 is stamped. A series of operations as the stamp producing device 1 is completed by irradiating the stamp main body 7 with light emitted from the xenon light emitting device 10 through the original film 8.
[0020]
When the cut sheet CS that has been manually fed is printed in the same manner as the original film 8, the cut sheet CS is discharged outside the apparatus without proceeding to the stamp section 7, and is used as a heading label of the stamp body 7 on the top surface of the grip portion of the stamp. It comes to be stuck. Next, the structure of each part will be described.
[0021]
As shown in FIGS. 1 and 2, the document film 8 fed out and printed from the film magazine 2 is configured to be conveyed through the upper surface of the light emitting device 10 mounted at the lower center of the creating apparatus main body 12. Is done. A thermal head 5 is disposed between the original winding side and winding side rolls 13 a and 13 b of the ink ribbon 9, and a platen 14 is attached below the thermal head 5. A guide rail 15 that guides and guides the original film 8 and the cut sheet CS to the thermal head 5 and a presser guide 16 that regulates lifting during the conveyance are disposed below the original roll 13a. ing. The ink ribbon supply device 13 is composed of the rolls 13a and 13b on the original winding side and the winding side.
[0022]
At the time of printing, the ink ribbon 9 and the original film 8 are sandwiched between the thermal head 5 and the platen 14. In this state, the platen 14 is driven while the thermal head 5 is driven, and the ink ribbon 9 and the original film 8 are intermittently fed in the direction of the take-up roll 13b. Characters and images corresponding to the shape are printed. The printed original film 8 is guided by a rear portion of the guide rail 15 and a transfer guide 17 disposed on the downstream side of the guide rail 15 in the conveyance direction of the original film 8, and on the downstream side of the conveyance guide in the conveyance direction. The paper is driven and conveyed by the pair of supply rollers 18, 18 and is sent to the stamp unit 6.
[0023]
As shown in FIGS. 1 and 2, the stamp producing apparatus 1 is provided with the above-described cut sheet supply port 3 on the upper surface of the left part of the main body, and the cut sheet CS inserted from the supply port 3 is inserted into the insertion port. 3 is fed into the inside by feed rollers 19 and 20 provided immediately after 3, and is conveyed to a position where printing by the thermal head 5 is possible by the sheet guide 21 and the guide rail 15. Then, after the printing is completed, it is sent out by the platen 14 and is taken out of the production apparatus main body 12 away from the ink ribbon 9.
[0024]
As shown in FIGS. 4 to 6, the film magazine 2 includes an open box-shaped magazine main body 22 that can accommodate a large number of document films 8 and a loading / unloading device 24. The magazine main body 22 includes a receiving plate 25 on which the document film 8 is placed, a detachable frame (an example of a take-out supply port) 26, and a main body frame 27. The receiving plate 25 and the detachable frame 26 are fulcrums in the left-right direction. P and Q are pivotally supported by the main body frame 27 so as to be swingable.
[0025]
When the film magazine 2 is set to be pushed into the production apparatus main body 12, the loading / unloading device 24 moves the front end side of the receiving plate 25 (downstream in the conveyance direction of the original film 8) in accordance with the pushing operation of the film magazine 2. When the film magazine 2 is pulled out from the production apparatus main body 12, the leading end side of the receiving plate 25 is fed out along with the pulling operation. The pull-down mechanism 24B is forcibly pulled down toward the magazine bottom 2a so as to move away from the roller 23.
[0026]
The push-up mechanism 24A has a push-up piece 28 mounted on the production apparatus main body 12 in a state of being protruded and biased by a spring 28a, and a hole formed in the magazine bottom 2a and the detachable frame 26 so as to allow the entry thereof. 29 and the like, and in response to the insertion operation of the film magazine 2, the receiving plate 25 is pushed up against the push-up piece 28. That is, the detachable frame 26 swings and rises around the fulcrum Q when both corners of the receiving plate 25 push up the separation claw 32 of the detachable frame 26 through the document sheet.
[0027]
The lowering mechanism 24B includes a torsion bar spring 30 that constantly presses and urges the detachable frame 26 downward (toward the magazine bottom 2a). When the interference with the receiving plate 25 is released, the detachable frame 26 is forcibly swung downward. That is, the push-up mechanism 24 </ b> A pushes up the detachable frame 26 against the urging force of the torsion bar spring 30.
[0028]
The detachable frame 26 includes first and second separation claws 31 and 32 that are located on the upstream side and the downstream side of the feeding roller 23 in the film transport direction and act on the original film 8 when the film magazine 2 is set. It is. The pair of first separation claws 31, 31 are hooked on the left and right ends of the original film 8, and the pair of second separation claws 32, 32 are hooked on both corners on the leading end side of the original film 8, The pulling mechanism 24B plays a role of transmitting a forcible lowering force so as to separate the original film 8 from the feeding roller 23 when the pulling mechanism 24B is operated, and is also a constituent part of the pulling mechanism 24B.
[0029]
Thus, only by mounting the film magazine 2 on the main body 12 of the production apparatus, a state in which the top end portion of the original film 8 is pressed and brought into contact with the feeding roller 23 appears. In this state, the feeding roller 23 is turned on. By driving and rotating, the original film 8 can be favorably conveyed toward the printing unit 4. When the film magazine 2 is pulled out from the production apparatus main body 12, the leading end of the original film 8 is forcibly moved away from the pressing contact state with the feeding roller 23 in the initial operation of the drawing.
[0030]
That is, the separation claws 31 and 32 are configured to be switchable between an operation position for forcibly separating the original film 8 from the slightly adhesive surface 23a and a retracted position separated from the feeding roller 23, and the separation claws 31 and 32 in the operation position. A torsion bar spring (an example of an elastic means) 30 is provided that presses and urges the claw toward the retracted position, and the separation claws 31 and 32 can be held at the operating position against the pressing urging force of the torsion bar spring 30. It is.
[0031]
As shown in FIG. 3, the outer peripheral surface of the feeding roller 23 is configured as a slightly adhesive surface 23a so that foreign matters such as dust and dust attached to the printing side surface of the original film 8 can be removed at the start of conveyance. . That is, the outer peripheral surface 23a of the feeding roller 23 is made of silicon rubber having a clay width of 45 mm and set in a range of 0.01N to 0.5N, and foreign matter is brought into contact with the original film 8 when it comes into contact with the original film 8. Thus, a cleaning action is generated in which the film is peeled off from the tape and adhered to the feeding roller 23.
[0032]
Incidentally, the slight adhesion surface 23a enhances the contact friction with the original film 8, and has an advantage that it can be reliably fed. In addition, when the film magazine 2 is inserted and set in the production apparatus main body 12 for a long period of time, it is predicted that the original film 8 will be relatively strongly adhered to the slightly adhesive surface 23a of the feeding roller 23. As described above, the four first and second separation claws 31 and 32 provided on the detachable frame 26 cause the pulling force of the lowering mechanism 24B to be applied to both sides of the printing surface (recording surface) 8A of the original film 8 respectively. Can be reliably separated and satisfactorily separated.
[0033]
As shown in FIG. 7, the width D1 of the recording area 8a in the original film 8 is set to be somewhat narrower than the film width, and the recording surface (corresponding to the recording operation side surface) 8A is recorded. The width D2 of the slightly adhesive surface 23a is set to be wider than the width D1 of the area 8a, and the first and second separation claws 31 and 32 described above both act on the original film 8 other than the recording area 8a. It is set to be.
[0034]
Of the pair of feed rollers 19 and 20 that feeds the cut sheet CS, the outer peripheral surface of the feed roller (an example of the conveying means) 19 on the thermal head 5 side is the same as the slightly adhesive surface of the feed roller 23. 19a, so that the foreign matter on the printing side of the cut sheet CS can be removed in front of the printing unit 4. However, a spring plate 47 for forcibly separating the cut sheet CS from the fine adhesive surface 19a is provided so that the cut sheet CS itself does not stick to the fine adhesive surface 19a.
[0035]
That is, as shown in FIG. 3, the width of the feeding roller 19 is made narrower than the width of the cut sheet CS, and the left and right action pieces 47a and 47a of the spring plate 47 are fed and pushed against the cut sheet CS at both end positions of the roller 19. By making contact with each other, the cut sheet CS is prevented from being wound around the fine-adhesion surface 19a of the feed roller 19, and is conveyed well. However, the width of the slightly adhesive surface 19a (= the width of the feeding roller 19) is set to be wider than the width of the printing surface (recording surface) in the cut sheet CS. The slightly adhesive surfaces of the feeding roller 19 and the feeding roller 23 are detachably wound so that they can be easily replaced with new ones when the cleaning function is deteriorated due to dirt.
[0036]
As shown in FIGS. 2, 3, and 6, first to third cleaning means 48, 49, 49 for the original film 8, the cut sheet CS, and the ink ribbon 9, in addition to the above-described fine adhesive surface. 50.

That is, the non-woven fabric 51 impregnated with a cleaning liquid (alcohol or the like) is arranged so as to contact the recording surface 8 a of the original film 8 to constitute the first cleaning means 48, and the mounting frame equipped with the non-woven fabric 51. (Not shown) is supported on the magazine lid 2b by bolts (or fitted). Therefore, if the magazine 2 is removed, the nonwoven fabric 51 can be easily replaced.
[0038]
The second cleaning means 49 is configured by disposing a non-woven fabric 53 having the same structure as that of the first cleaning means 48 so as to act on the printing side surface of the cut sheet CS at a position on the near side of the upper feed roller 19. This nonwoven fabric 53 is also detachable by means such as bolting or fitting.
[0039]
The third cleaning means 50 is a non-woven fabric 54 (which also has the same structure as the first cleaning means 48) that is in contact with the side opposite to the head of the ink ribbon 9 between the original roll 13a and the thermal head 5. The presser guide 55 is arranged on the head side of the ribbon 9 in order to ensure the contact action. This nonwoven fabric 54 is also detachable by means such as bolting or fitting. In addition, it is convenient if each nonwoven fabric 51, 53, 54 is composed of ultra-fine long fibers and is stuck with a double-sided tape, and it may be slightly adhesive.
