Description

Core, ink ribbon cassette and ink ribbon cassette holding mechanism of thermal transfer magnetic field {WINDING CORE FOR INK RIBBON OF THERMAL TRANSFER PRINTER, INK RIBBON CASSETTE, AND INK RIBBON CASSETTE HOLDING MECHANISM}

In general, letters and symbols are marked on the wires to show the types and functions of the wires assembled in the electrical equipment such as switchboards. In this case, since it cannot be printed directly on the wire, the letter or symbol is printed on a short tube and the wire is inserted into the tube. Moreover, although the tape which displayed the character and the content was attached to the front and back cover of a book or a binder, this tube also printed the characters, such as a name on the surface.

In any case, printing is performed by a thermal transfer printing machine, but the thermal transfer printing machine pushes a tube or tape to the surface of a material such as a platen roller, pushes the ink ribbon and the printing head thereon, and heats the printing head. It melts the ink in the ink ribbon and thermally transfers letters and symbols to tubes and tapes.

Before the ink ribbon cassette is attached to the printing machine, the take-out core and the winding core of the ink ribbon are in a free state, so the winding of the ribbon wrapped around the core may be loosened. There was a case. In addition, since the ink ribbon is a consumable item, the used ink ribbon must be removed and a new one loaded, but conventionally, a cassette loading method in which the ink ribbon is stored in a cassette in advance and loaded in each printing machine is adopted.

The advantage of the cassette method is that it is easy to handle thin ink ribbon and has good loadability. On the other hand, as a disadvantage, when the ink ribbon is used up, all the cassettes are discarded, which damages the environment and is also expensive.

There is a loading method for winding the core to replace only the ink ribbon wound on the core for the cassette method. The handling is different from the cassette method, but the unit cost is low and the waste is small, so the load on the environment is small.

In addition, when the ink ribbon cassette is mounted on the thermal transfer printing machine, the ink ribbon cassette must be held so as not to move. Therefore, conventionally, the ink ribbon cassette is pressed or held together by the elasticity of the synthetic resin member.

However, there is a type of ink ribbon cassette which forms a rotation stop by making an incision in a portion of the cassette container so as not to rotate arbitrarily when the ink ribbon cassette is not mounted and engaging the ink ribbon shaft. In a cassette provided with this kind of rotation stop, the tape reel rotating shaft provided on the printing base body is pushed up by the rotation stop to release the coupling of the tape reel. According to this method, since the pushing force applied to the ink ribbon cassette at the time of release is large, the holding mechanism by the conventional synthetic resin member cannot be sufficiently maintained.

The present invention relates to an ink ribbon recommended core and an ink ribbon cassette used in a thermal transfer printing machine.

The present invention also relates to an ink ribbon cassette holding mechanism for strongly holding an ink ribbon cassette in a thermal transfer factor machine.

In order to solve the first problem, the thermal transfer ink ribbon cassette according to the present invention is a thermal transfer ink ribbon cassette in which a core for which ink ribbon is recommended is stored in a cassette body, wherein the core is rotated between an upper wall and a bottom wall of the cassette body. It is arranged so as to be free, the bottom wall is formed with a through hole for coupling the lower end of the core center hole to the ink ribbon rotation axis of the thermal transfer printing machine, the upper wall and the short axis portion coupled to the upper end of the center hole and the core center The flap provided with the engaging hook couple | bonded with the clutch part radially formed around the upper end of a ball is provided so that it can rock up and down.

The flap may be formed by inserting a groove into the upper wall of the cassette body.

Moreover, you may provide the opening part which can insert and remove the said core in the side wall of the said cassette body.

In order to solve the second problem, the ink ribbon recommended core according to the present invention includes a tube portion, a center hole formed in the inside of the tube portion, a recess formed in an upper end of the tube portion, and a protrusion formed in the recess. And a plurality of clutch portions provided radially from and having a tapered surface, wherein the tapered surface of the clutch portion is made thinner than the proximal portion on the recessed side, and the thickness of the core center side portion is made thinner. It is characterized by making it inclined with respect to the perpendicular direction of the said recessed part by making it thinner than the thickness of the part of a core outer peripheral side.

The clutch portion may have the first side surface formed as a tapered surface of the clutch portion and the second side surface formed as a surface substantially perpendicular to the recessed portion.

Moreover, the said cylinder part may be provided with the protrusion formed in the longitudinal direction of an inner surface.

Moreover, a flange may be provided in each of the upper and lower surfaces of the cylinder portion, and a small diameter portion may be formed on the outer surface of the cylinder portion.

Moreover, in order to solve the said 2nd subject, you may make it the ink ribbon recommended core set combining the 1st core and the 2nd core which respectively have the characteristics of the ink ribbon recommended core which concerns on this invention mentioned above.

Note that the above-mentioned features as the ink ribbon recommendation core according to the present invention in the first core and the second core do not need to be common, and may be constituted by different features.

In order to solve the third problem, the ink ribbon cassette holding mechanism of the thermal transfer printing machine according to the present invention comprises: a first slide member for relatively moving the platen roller and the printing head to the thermal transfer printing machine body in a relatively pressing or half direction; A second slide member disposed below the ribbon cassette is provided to interlock with the first slide member, and the second slide member includes an ink ribbon when the first slide member moves in the pressing direction from the platen roller and the print head in the pressing state. It is characterized by forming a coupling portion for coupling to the cassette.

In addition, the engaging portion is formed in an inverted L-shape from the erected piece standing up from the second slide member and the engaging hook protruding in the transverse direction from the tip of the erected piece, and the inclined portion inclined from the base to the tip is formed inside the engaging hook. The inclined portion may be coupled to the bottom wall of the ink ribbon cassette.

First, with reference to FIGS. 1-7, it demonstrates about the structure of the thermal transfer printing machine which concerns on this invention, and especially an ink ribbon cassette holding mechanism and an ink ribbon cassette are demonstrated.

In Fig. 1, reference numeral 101 denotes a thermal transfer printing element body. The platen roller 102 and the print head 103 are provided in the thermal transfer printing machine main body 101. The platen roller 102 is fixed at a fixed position. The print head 103 is provided to be freely rotated in the horizontal direction in the print base body, and is pressed to be separated from the platen roller 102 by a spring (not shown). The print head 103 is coupled to the standing piece 105 of the first slide member 104. For this reason, as the first slide member 104 slides, the print head 103 is movable in the pressing or displacing direction with respect to the platen roller 102.

The platen roller 102 and the print head 103 may move in a relatively pressing or opposing direction. Therefore, the platen roller 102 may be interlocked with the first slide member 104 and the platen roller 102 may be moved in the pressing direction in the fixed printing head 103.

Next, two rotary shafts 106 and 107 are provided on the thermal transfer printing machine main body 101, and ink ribbon cassettes 108 are mounted on these rotary shafts 106 and 107. An ink ribbon 109 and its winding reel 110 are housed in the ink ribbon cassette 108. In addition, as shown in FIG. 2, sidewalls of both ends corresponding to a line P intersecting between the ink ribbon 109 and the winding reel 110 are cut in the vicinity of the bottom wall 111 of the cassette 108 to receive the coupling part 112. 113 is formed and a through hole 114 is formed at one end.

Further, a plate-shaped second slide member 115 is disposed below the ink ribbon cassette 108. The second slide member 115 is preferably made of a material having high strength such as metal, and a pair of coupling portions 118 and 119 are formed at both ends of one side thereof as shown in FIG. These coupling portions 118 and 119 are made up of standing pieces 116 and standing pieces 117 protruding transversely from the tip of the standing pieces 116, respectively, and standing pieces 116 and standing pieces ( 117) in an inverted L shape. Inside the respective engaging pieces 117, an inclined portion 120 inclined from the base to the tip is formed. In addition, the second slide member 115 is pressurized to move toward the first slide member 104 side by the tension spring 121.

The coupling receiving parts 112 and 113 at both ends of the ink ribbon cassette 108 are formed to be mounted at positions corresponding to the coupling parts 118 and 119 of the second slide member 115 at the time of mounting.

In addition, a substantially triangular hole 122 is formed at the distal end side of the second slide member 115 as shown in FIG. 4, and the projection 123 formed at the distal end of the first slide member 104 is formed in the triangular hole 122. Combining Accordingly, the second slide member 115 is configured to slide in conjunction with the first slide member 104 in a predetermined range. The slide amount of the first slide member 104 is set to about twice the slide amount of the second slide member 115.

In the above configuration, when the ink ribbon is replaced, the platen roller 102 and the print head 103 are separated by sliding the first slide member 104 to the right in the drawing by appropriate means. Move it.

When the first slide member 104 is slid in this manner, the protrusion shaft 123 is located in front of the triangular hole 122 of the second slide member 115, that is, on the portion shown in FIG. 4 on the first slide member 104 side. Since the projection shaft 123 only moves the inside of the triangular hole 122 until it slides about half of the amount of the slide, the second slide member 115 does not move. When the first slide member 104 exceeds half of the slide amount, the protrusion 123 contacts the inner wall of the triangular hole 122 shown in FIG. 5, and when the first slide member 104 moves further, the protrusion 123 moves to the second slide member 115. ), The second slide member 115 also interlocks with the first slide member 104 and moves to the position of FIG. 6 in response to the spring of the tension spring 121.

Next, the ink ribbon 109 is drawn out between the platen roller 102 and the print head 103, and the used ink ribbon cassette 108 is separated to form a new ink ribbon on the rotation axis of the thermal transfer printing machine main body 101. It is mounted via the cassette 108. At this time, as shown in FIG. 3A, one coupling portion 118 of the second slide member 115 passes through the through hole 114 of the bottom wall 111 of the ink ribbon cassette 108 to the middle portion thereof. In addition, after setting a material (not shown) between the print head 103 and the platen roller 102, the first slide member 104 is slid in the reverse direction to move the print head 103 to the platen roller 102. Move to press on.

When the first slide member 104 is slid, the protrusion 123 is located inside the triangular hole 122 of the second slide member 115 as shown in FIG. 6, but as shown in FIGS. 1 and 3 (b). Since the slide member 115 is always urged to move toward the first slide member 104 by the spring force of the tension spring 121, the slide member 115 also moves in conjunction with the first slide member 104. . When the second slide member 115 is moved by the spring force, the engaging portions 118 and 119 also move in the same direction, and the inclined portion 120 of the engaging hook 117 of the engaging portions 118 and 119 is The ink ribbon cassette is coupled to the coupling receiving portions 112 and 113 of the bottom wall 111 of the ink ribbon cassette 108, but the bottom wall 111 is pushed downward by the inclined portion 120 of the coupling hook 117. 108 is held firmly.

At this point of engagement, the second slide member 115 stops at the position in FIG. 5 and no more moves there. Meanwhile, since the first slide member 104 moves again, the protrusion shaft 123 moves toward the front of the triangular hole 122 as shown in FIG. 4, and the print head 103 is pressed against the platen roller 102. This makes it possible to print.

As described above, since the second slide member 115 moves together with the first slide member 104 and is coupled to the ink ribbon cassette 108, the second slide member 115 is made of a high-strength material such as metal to form ink. The ribbon cassette 108 can be reliably held by the second slide member 115. Therefore, when the ink ribbon cassette 108 is mounted on the printing machine main body, the rotary stops 125 and 107 of the ink ribbon cassette 108 are pushed up and rotated to the rotating shafts 106 and 107 provided in the printing base body as shown in FIG. Even in the case of releasing the ink ribbon cassette 108, the ink ribbon cassette 108 can be held firmly.

In addition, the holding of the ink ribbon cassette 108 is completed in the first half of the stroke of the second slide member 115, and then the holding of the ink ribbon cassette 108 is maintained after the mechanical contact with the first slide member 104 is blocked. For example, the second slide member 115 does not press the print head 103 and the print head 103 is pressed against the platen roller 102 at a constant pressure, and thus there is no influence on the print quality.

The above-mentioned first slide member 104 and the second slide member 11 are moved in the same manner when replacing not only the ink ribbon cassette 108 but also consumables such as printing tubes and tapes.

Further, the engaging portion of the ink ribbon cassette and the portion of the second slide member engaging with the engaging portion are not limited to the above-described example.

Subsequently, an ink ribbon recommended core and an ink ribbon cassette will be described with respect to the configuration of the thermal transfer printing machine according to the present invention with reference to Figs.

8 (a) and 8 (b) are perspective views of the ink ribbon cassette, FIG. 9 is a bottom view of the state excluding the bottom wall, and FIGS. 10 (a) and 10 (b) are respectively a perspective view and a sectional view of the core. In the figure, reference numeral A denotes a thermal transfer ink ribbon cassette. The ink ribbon cassette A stores the core 202 for which the thermal transfer ink ribbon 201 is recommended and the core 203 for winding up the ink ribbon 201 in the cassette body 204. And the winding core 203 is made of synthetic resin, and the flange (b) is provided on the upper and lower ends of the tube part (a) in the center to form a central hole (206) inside the tube part (a). A recess 205 is formed in the recess 205, and a plurality of protrusion pieces 207 are formed radially from the center hole 206. Moreover, the protrusion 208 is formed in the inner surface of the said cylinder part a in the longitudinal direction.

In Figs. 10A and 10B, the core is illustrated by taking the case of the winding core 203 as an example. The winding core 203 is provided with a small diameter portion 261 on the outer surface of the tube portion a, and forms a step. The ink ribbon 201 after being printed by the printing head (not shown) may be distorted by the influence of the portion where the ink is printed and consumed. Therefore, when the ink ribbon 201 is wound around the winding core 203, the outer edge portion of the ink ribbon 201 in the longitudinal direction may be smoothly wound. However, by providing the small diameter portion 261, the ink ribbon 201 after being sent from the core 202 and printed by the printing head can be smoothly wound to the end.

On the other hand, as shown in Figs. 9, 13 and 14, the core 202 need not be provided with the small diameter portion 261 and the flange (b) of the cylinder portion (a), and the ink ribbon 201 is placed on the smooth cylinder portion (a). You can also wind it yourself. By not providing the small diameter portion 261 and the flange b of the cylinder portion a, the core body 202 and the winding core 203 are arranged closer to each other in the cassette body 204 so that the cassette body can be miniaturized. Can be.

In addition, arrangement | positioning of the core 202 and the winding core 203 is not specifically limited, It is good also as a reverse arrangement to what was shown in FIG.

As shown in FIGS. 10A and 10B, the clutch portion 207 of the core 202 and the winding core 203 is provided with a tapered surface inclined with respect to the vertical direction of the recess 205. As shown in Fig. 10 (a), the tapered surface of the clutch portion 207 makes the thickness of the tip portion that strikes the upper core side thinner than the proximal portion on the concave portion 205 side, and the thickness of the core center side portion is the thickness of the core outer peripheral portion. It is formed by making it thinner. Further, the clutch portion 207 has only one side surface (first side surface 207a) of the two side surfaces engaged with the engagement hook 221 described later as a tapered surface, and the other side surface (second side surface 207b) is concave. It is set as the surface which is substantially perpendicular with respect to the part 205.

The cassette body 204 is formed in a case shape from the upper wall 209, the bottom wall 210, and the side wall 211, and accommodates the core 202 and the winding core 203 of the ink ribbon 201 so as to rotate freely therein. A pair of small ribbons for exposing the ink ribbon 201 while the ink ribbon 201 drawn out from the core 202 is wound on the winding core 203 is provided. 213). The housing portion 212 is formed inside the arc-shaped abrupt 214 for positioning the ink ribbon core 202 and the winding core 203 on the bottom wall 210. A space is formed inside the ribbon sopley 213, and the printing head (not shown) of the thermal transfer printing machine is formed in this space.

In addition, grooves may be formed in sidewalls of the upper and lower ends of FIG. 8A as in the coupling receiving parts 112 and 113 of the ink ribbon cassette 108 shown in FIG. Similarly, the through-holes may be formed in the bottom wall 210 of the cassette body 204 like the through-holes 114 in the ink ribbon cassette 108 shown in FIG. By forming the engaging receiving portion and the through-hole as described above and combining with the above-described ink ribbon cassette holding mechanism, the ink ribbon cassette mounted on the thermal transfer printing machine can be reliably held.

Two flaps 215 are formed on the upper wall 209 of the cassette body 204 at positions corresponding to the core 202 and the winding core 203. That is, the flap 215 is formed inside the grooves 217 and 218 by forming two substantially U-shaped grooves 217 and 218 long and short on the upper wall 209 so as to face each other. An L-shaped connecting portion 219 is formed between 217 and 218. As illustrated in FIG. 11, a short portion 220 is formed at a portion of one end of the flap 215 corresponding to each center of the core 202 and the winding core 203, and the upper end portion of the short portion 220 is formed. Protruding engaging hooks 221 are formed at portions corresponding to the clutch portions 207 of the core 202 and the winding core 203. In addition, the end portion on the opposite side of the flap 215 is formed with a pressing portion 222 that can be pressed from the outside. When the pressing part 222 is pressed, the flap 215 swings up and down about the connecting part 219 in a seesaw shape.

According to the above configuration, the short axis portion 220 of the flap 215 of the cassette body 204 is inserted into the ink ribbon core 202 and the central hole 206 of the winding core 203 in the cassette body 204. Therefore, as shown in FIG. 11, the ink ribbon core 202 and the winding core 203 are free to rotate about the short axis 220. In addition, since the engaging hook 221 of the flap 215 is coupled to the radial clutch portion 207 around the upper end of the ink ribbon core 202 and the center hole 206 of the winding core 203, the core 202 or The winding core 203 is also locked and cannot be rotated. Therefore, when not loaded into the thermal transfer printing machine can not be rotated at will. When the ink ribbon 1 becomes much larger, as shown in Fig. 12, the pressing portion 222 of the flap 215 is pushed in to swing the flap 215, and the engaging hook 221 and the ink ribbon core 202 or the winding core are wound. After releasing the engagement with the clutch portion 207 of the 203, the core 202 or the winding core 203 exposed to the through hole 216 (see FIG. 8) of the bottom wall 210 is turned with a finger or a rod. do.

The flap may be formed separately from the upper wall of the cassette without being integrally formed with the upper wall of the cassette.

As shown in Fig. 12, when the ink ribbon cassette of the above configuration is loaded into the thermal transfer printing machine, the rotary shaft 226 provided in the thermal transfer printing machine is inserted into the through hole 216 formed in the bottom wall 210 of the cassette body 204. Just do it. In addition, when the ink ribbon cassette is inserted into and fixed to a predetermined position of the thermal transfer printer by means not shown, the upper end of the rotating shaft 226 pushes up the short part 220 of the flap 215, so that the flap 215 swings. And, the engaging hook 221 rises and the engagement with the clutch portion 207 is released and the locked state is released. On the outer surface of the rotating shaft 226, a protrusion 223 is formed along its longitudinal direction. When the rotating shaft 226 is inserted into each of the center holes 206 of the ink ribbon core 202 and the winding core 203 in the through hole 216 of the ink ribbon cassette A, the protrusion 223 of the rotating shaft 226 and Since the protrusions 208 of the center hole 206 are coupled to each other, when the rotating shaft 226 rotates, the ink ribbon core 202 and the winding core 203 also rotate.

As described above, in the present embodiment, only the first side surface 207a of the two side surfaces engaged with the engagement hook 221 in the clutch portion 207 is a tapered surface, and the second side surface 207b has a concave portion 205. I assume approximately vertical in). Therefore, the resistance to rotation of the core 202 and the winding core 203 in the locked state can be changed depending on the direction in which the core is rotated. That is, when the tapered surface (first side surface 207a) of the clutch unit 207 and the engaging hook 221 are rotated in the direction of engagement, the second side surface 207b and the engaging hook 221 of the clutch unit 207 It can be easily rotated as compared with the case of rotating in the coupling direction.

When the ink ribbon 201 is loosened while the ink ribbon cassette is not loaded in the thermal transfer machine, the user needs to rotate the winding core 203 itself. In such a situation, by adopting the above-described configuration of the clutch portion, it is possible to prompt the user to rotate only in one direction and to ease the looseness of the ink ribbon 201.

8, the inclined surface 216a is provided at the edge of the through hole 216 corresponding to the winding core 203. When the winding core 203 is rotated while the ink ribbon cassette is not loaded on the thermal transfer factor by the inclined surface 216a, the winding core 203 exposed from the bottom wall 210 of the cassette body 204 is rotated. Some parts can be brought into smooth contact with the user's finger. Thereby, the winding core 203 can be easily rotated when the ink ribbon 201 becomes loose.

In addition, although FIG. 8 shows the example in which the inclined surface 216a was provided only in the through-hole 216 corresponding to the winding core 203, you may provide in the through-hole 216 corresponding to the core 202. FIG.

Fig. 13 is a plan view of another ink ribbon cassette. Like the cassette body 304 shown in this figure, the side walls 211 may be cut out to form the openings 224 at both sides of the cassette body. The opening 224 has a size that allows the ink ribbon core 202 and the winding core 203 to be inserted into and removed from the inside. For this reason, the ink ribbon recommendation core set which consists of the ink ribbon core 202 and the winding core 203 can be attached or detached freely. That is, when the ink ribbon recommended core set is attached, the pressing portion 222 of the flap 215 is pushed hard so that the shortened portion 220 is held up, and the ink ribbon core 202 or the winding core 203 is opened in the opening portion. It inserts from 224, it is accommodated in the accommodating part 212, and the short part 220 of the flap 215 may be lowered. On the other hand, similarly when the ink ribbon core 202 or the winding core 203 is removed, the pressing part 222 of the flap 215 is pushed hard so that the shortening part 220 is floated up, and the ink ribbon core ( The 202 or the winding core 203 may be taken out of the opening.

Fig. 14 is a plan view of another ink ribbon cassette. The cassette body 404 shown in FIG. 14 has openings 224a and 224b similarly to the cassette body shown in FIG. 13, but has a convex structure on the bottom wall near the opening 224a in which the core 202 is inserted and removed. 225 is formed. By providing the convex 225, the contact resistance between the core and the bottom wall of the cassette body when the core is inserted and detached can be reduced, so that the ink ribbon can be replaced more easily. The cassette body 404 shown in Fig. 14 with the convex 225 removed is omitted in the same manner as the cassette body 204 and 304 shown in Figs. In addition, although the example which provided three convex tanks 225 only in the opening part 224a side is shown in FIG. 14, the shape, arrangement | positioning, and the number of strands of a convex tank are not specifically limited. Moreover, you may provide a convex to the bottom wall of the opening part 224b by the winding core 203 side.

The present invention is not limited to the above embodiments, and various modifications are possible within the technical scope of the present invention, and it is natural that the present invention has been modified.

This application is based on the Japanese patent application (Japanese Patent Application No. 2002-54824) of the February 28, 2002 application and the Japanese patent application (Japanese Patent Application No. 2002-54825) of the February 28, 2002 application. Put it here for reference.

As described above, in the ink ribbon recommended core and ink ribbon cassette of the present invention, since the ink ribbon 201 is loaded into the cassette body 204, the rotating shaft 226 provided in the thermal transfer printing machine is loaded when the thermal transfer printing machine is loaded. It is sufficient to insert the through-hole 216 formed in the bottom wall 210 of the cassette body 204 so as to be loaded. Therefore, the ink ribbon 201 can be easily handled and loaded.

In addition, when the flap is integrally formed with the upper wall of the cassette, the loosening of the ink ribbon when it is not attached can be eliminated with the minimum number of parts.

In addition, when an opening is formed in the side of the cassette body 204, only the ink ribbon 201 wound on the core 202 can be replaced, and thus it can be employed as a core winding charging method. As a result, the handling is simple, the unit price is low, and the disposal part is small, so that the load on the environment may be small, and the cassette type or the core winding type can be coped with.

In the ink ribbon cassette holding mechanism of the thermal transfer printing machine of the present invention, the second slide member moves together with the first slide member to be coupled to the ink ribbon cassette. As a result, the ink ribbon cassette mounted on the thermal transfer printing machine can be reliably held by the second slide member.
