  As shown in FIG. 13B, in the case of the roll sheet holder 3 in which the roll sheet 3A having the minimum width is wound around the core 3B, first, the mounting member for the positioning holding member 12 of the roll sheet holder 3 is used. 13 is inserted into the positioning groove 16 of the holder support member 15. And while making the lower end surface of the 3rd extension part 44 of the guide member 20 of this roll sheet holder 3 contact | abut on the mounting part 21, the 4th extension part 45 of this guide member 20 of the mounting part 21 is made to contact | abut. It is made to fit in 2nd positioning groove part 21D formed in a conveyance direction rear side corner | angular part. And the lower end edge part of the 1st extension part 42 of this guide member 20 is inserted in the positioning recessed part 4A formed in the bottom face part of the roll sheet holder accommodating part 4, and is made to contact | abut. At the same time, the sheet determination portion 60 formed at the lower end portion of the extension portion 56 of the positioning holding member 12 of the roll sheet holder 3 is inserted into the determination recess 4B formed inside the base end portion of the holder support member 15. At the same time, the elastic locking piece 12 </ b> A is engaged with an engagement recess 15 </ b> A formed at the base end portion of the holder support member 15. Thereby, the roll sheet holder 3 is detachably attached to the roll sheet holder storage part 4.

  Subsequently, in a state where the lever 27 is rotated upward, the one side edge of the roll sheet 3A is brought into contact with the inner surface of the guide member 20, and the roll sheet 3A is pulled out. The other side edge portion is inserted into the insertion port 18 while being brought into contact with the guide rib portion 23 erected on the side edge portion of the insertion port 18. Thereafter, by rotating the lever 27 downward, the leading end portion of the roll sheet 3A is pressed against the platen roller 26 by the thermal head 31, and printing is possible.

  Next, the appearance of the label printer 1 according to this embodiment will be described. FIG. 14 is a perspective view showing an appearance when the roll sheet holder 3 is attached to the label printer 1 according to the present embodiment. As shown in FIG. 14, in the main body housing 2 of the label printer 1 according to the present embodiment, the upper cover 5 made of transparent resin has a rear upper end edge so as to cover the upper side of the roll sheet holder storage portion 4. The roll sheet 3A of the roll sheet holder 3 that is detachably attached to the roll sheet holder storage portion 4 can be seen through the transparent resin upper cover 5.

  In this regard, the roll sheet 3 </ b> A of the roll sheet holder 3 has a plurality of medium information 101 of “64 mm × 30 m” which is a description that the width of the roll sheet holder 3 is “64 mm” and the length is “30 m”. One or more media information 101 can be seen through the upper cover 5 made of transparent resin. This medium information 101 is continuously printed over the entire area in the longitudinal direction on the release paper bonded to one side of the heat-sensitive sheet of the roll sheet 3A via an adhesive. Furthermore, as described above, the release paper bonded to one side of the heat-sensitive sheet via an adhesive is wound outward with respect to the core 3B. Therefore, even if the remaining amount of the roll sheet 3A of the roll sheet holder 3 is reduced, the one or more pieces of medium information 101 can be continuously viewed through the upper cover 5 made of transparent resin.

  Further, when the remaining amount of the roll sheet 3A of the roll sheet holder 3 is reduced, the second extending portion 43 of the guide member 20 is exposed, and therefore each scale 43A representing the winding length 10m, 20m of the roll sheet 3A. 43B can be seen through the upper cover 5 made of transparent resin.

  That is, the roll sheet holder 3 according to the present embodiment is in a roll shape in which the roll sheet 3A is wound around the core 3B. In this regard, the release sheet constituting the roll sheet 3A has medium information 101 in advance. Therefore, the medium information 101 appears on the outside.

  On the other hand, the label printer 1 according to the present embodiment attaches the roll sheet holder 3 according to the present embodiment to the roll sheet holder storage portion 4 of the main body housing 2. The roll sheet holder 3 is covered by the upper cover 5 which is placed so as to be freely opened and closed.

  However, as shown in FIG. 14, the upper cover 5 covering the roll sheet holder 3 is made of transparent resin at least at the upper surface of the curved surface, so that the medium information 101 appearing outside the roll sheet holder 3 is stored in the main body. It can be seen through the upper cover 5 placed on the housing 2 so as to be freely opened and closed. Therefore, in the label printer 1 and the roll sheet holder 3 of the present embodiment, the medium information 101 can be visually observed from the outside even when the roll sheet holder 3 is attached to the label printer 1.

  Further, in the label printer 1 according to the present embodiment, the first positioning groove portion 16 into which the mounting member 13 protruding from the outer end face of the flange portion 55 and the extension portion 56 of the roll sheet holder 3 is fitted is the roll sheet holder. Since it is formed on the holder support member 15 erected on the one side edge of the storage unit 4, the roll sheet holder 3 is reliably positioned with reference to the one side edge of the roll sheet holder storage 4. Thus, each roll sheet 3A having a plurality of types of sheet widths can be accurately positioned.

  Accordingly, as shown in FIGS. 13A and 13B, even if the roll sheet holder 3 having the roll sheets 3A having different sheet widths is attached to the label printer 1, one side of the roll sheet holder storage section 4 is provided. The edge side of the roll sheet 3 </ b> A of the roll sheet holder 3 is always adjacent to the end edge.

  On the other hand, in the roll sheet 3 </ b> A of the roll sheet holder 3, as shown in FIG. 14, on the edge side adjacent to the one side edge of the roll sheet holder storage portion 4 that serves as a positioning reference for the roll sheet holder 3, Information 101 is printed in advance.

  Therefore, even when the roll sheet holder 3 having the roll sheets 3 </ b> A having different sheet widths is mounted on the label printer 1, the roll sheet holder 3 always has a roll on the side edge of the roll sheet holder storage portion 4. Since the edge side of the sheet 3A is adjacent to each other, the medium information 101 printed on the edge side is present, so that even if the sheet width is different, the existence position of the medium information 101 is within a certain area. It is easy to confirm the medium information 101 from the outside.

  Accordingly, the upper cover 5 that is mounted on the main body housing 2 so as to be freely opened and closed is not limited to being formed of a transparent resin except for a portion that covers an upper portion of a certain area where the position where the medium information 101 exists. 101 can be confirmed from the outside. For example, by forming both side edge portions of the upper part of the curved surface of the upper cover 5 with an opaque resin, the mechanisms located on both outer sides of the roll sheet holder 3 can be obscured, giving a clean impression in design. be able to.

  The above points have been referred to the medium information 101 printed in advance on the edge side of the roll sheet 3 </ b> A of the roll sheet holder 3, but the same can be said with respect to the code information printed below the medium information 101. (See FIG. 14).

  Next, the fixing type heat sensitive sheet will be described. The fixing type heat-sensitive sheet used in this embodiment is a heat-sensitive sheet having one heat-sensitive recording layer described in JP-A No. 2003-1939. As will be described later, the fixing-type heat-sensitive sheet has a heat-sensitive recording layer formed on one side of the substrate. Since this heat-sensitive recording layer is a single layer, it is compatible with printing in a single color. In general, a fixing type heat-sensitive sheet has a property of developing color when heated and fixing the color when irradiated with light.

  Next, the light blocking protection sheet will be described. The light blocking protection sheet is a black resin sheet and has a property of absorbing natural light and ultraviolet rays. Black paper may be used as long as it absorbs natural light and ultraviolet rays.

  Next, a method for bonding the light blocking protection sheet and the fixing type heat sensitive sheet will be described. A light-adhesive adhesive is thinly applied to the entire surface of the light-blocking protective sheet facing the fixing-type heat-sensitive sheet, and the light-blocking protective sheet coated with the adhesive is superimposed on the fixing-type heat-sensitive sheet. After that, it is made to adhere by pressing. Thereby, when the light shielding protective sheet is peeled off from the fixing type heat sensitive sheet after bonding, the light shielding protective sheet is not adhered to the fixing type heat sensitive sheet again. Since this technique is well known and is often used for postcards that need to hide information, a detailed description is omitted here.

  Next, among the roll sheet 3A (corresponding to a printing apparatus sheet and a printing apparatus roll paper) which is a main part of the present invention, details of various roll sheets 3A having a fixing type heat-sensitive sheet will be described with reference to the drawings. To do.

  FIG. 15 is a plan view schematically showing the configuration of various roll sheets 3A having a fixing type heat sensitive sheet and release paper. FIG. 15A shows a normal type roll sheet 300 in which the fixing type heat-sensitive sheet constituting the roll sheet 3A is simply a long tape. FIG. 15B shows a first die-cut type roll sheet 301 in which the fixing type heat-sensitive sheet constituting the roll sheet 3A is composed of a plurality of labels. FIG. 15C shows a first die-cut type roll sheet in which the fixing type heat-sensitive sheet constituting the roll sheet 3A is a long tape and can be separated into a plurality of labels by die-cutting. 302 is shown. FIG. 16 is a cross-sectional view in the width direction schematically showing the configuration of a roll sheet 3A having a fixing type heat sensitive sheet and release paper. FIG. 16A is a cross-sectional view in the width direction according to the present embodiment of a normal type roll sheet 3A having a fixing type thermal sheet and release paper, and FIG. 16B is a normal type having a fixing type thermal sheet and release paper. FIG. 16C is a cross-sectional view in the width direction according to another embodiment of the roll sheet 3A of the type, and FIG. 16C is a cross-section in the width direction according to another embodiment of the normal type roll sheet 3A having the fixing type heat-sensitive sheet and release paper. FIG. FIG. 17 is a cross-sectional view in the width direction schematically showing the configuration of a roll sheet 3A having a fixing type heat sensitive sheet and no release paper. The cross section in the width direction at the portion where the label of the die cut type roll sheet 3A is arranged is the same as that of the normal type roll sheet 3A, and is not shown.

  First, the normal type roll sheet 300 will be described. As shown in FIGS. 15A and 16A, the normal type roll sheet 300 includes a long light blocking protection sheet 303, a long fixing type heat sensitive sheet 309, and a long pressure sensitive adhesive. 306 and a long release paper 307 are laminated in this order. The fixing type thermal sheet 309 has a thermal recording layer 304 formed on one side of the substrate 305. The light blocking protection sheet 303 is adhered to the printing surface side (the thermal recording layer 304 side) of the fixing type thermal sheet 309. The pressure-sensitive adhesive 306 is attached to the surface opposite to the printing surface of the fixing type heat-sensitive sheet, and a release paper 307 is bonded to the pressure-sensitive adhesive 306. At this time, the width of the fixing type thermal sheet 309 and the width of the light blocking protection sheet 303 are configured to be the same length, and the adhesive is attached to the entire surface on the opposite side of the printing surface of the fixing type thermal sheet 309. Yes. The width of the release sheet 307 is larger than the width of the fixing type thermal sheet 309 and the light blocking protection sheet 303, and the fixing type thermal sheet 309 and the light blocking protection sheet 303 are arranged at the center in the width direction of the release sheet 307. Yes. Since the width of the fixing type thermal sheet 309 and the width of the release paper 307 are thus different, the release paper 307 can be easily peeled off from the fixing type thermal sheet 309.

  Next, the first die-cut type roll sheet 301 will be described. As shown in FIGS. 15B and 16A, the first die-cut roll sheet 301 includes an elongate light blocking protection sheet 303, a fixing type heat sensitive sheet 309 including a plurality of labels, and a plurality of labels. And an adhesive 306 having the same shape and a long release paper 307 are laminated in this order. The fixing type thermal sheet 309 has a thermal recording layer 304 formed on one side of the substrate 305. Similar to the normal type roll sheet 300, the light blocking protective sheet 303 is adhered to the printing surface side (the thermal recording layer 304 side) of the fixing type thermal sheet 309, and the adhesive 306 is the printing side of the fixing type thermal sheet. The release paper 307 is adhered to the adhesive 306.

  FIG. 15B shows that the labels constituting the fixing type thermal sheet 309 are arranged in the longitudinal direction of the roll sheet 301 with a predetermined interval. In this figure, two labels are shown on the left and right. FIG. 16A schematically shows a cross section when the roll sheet 301 is cut in the width direction at a portion where the label is arranged in the roll sheet 301. At this time, the width of the fixing type thermal sheet 309 and the width of the light blocking protection sheet 303 are configured to be the same length, and the adhesive is attached to the entire surface on the opposite side of the printing surface of the fixing type thermal sheet 309. Yes. The width of the release sheet 307 is larger than the width of the fixing type thermal sheet 309 and the light blocking protection sheet 303, and the fixing type thermal sheet 309 and the light blocking protection sheet 303 are arranged at the center in the width direction of the release sheet 307. Yes. Since the width of the fixing type thermal sheet 309 and the width of the release paper 307 are thus different, the release paper 307 can be easily peeled off from the fixing type thermal sheet 309.

  On the other hand, a portion of the roll sheet 301 where the label constituting the fixing type heat-sensitive sheet 309 is not disposed is composed of a light shielding protective sheet 303 and a release paper 307 layer.

  This time, in the description of the first die-cut type roll sheet 301, the length in the width direction of the roll sheet 301 in the label constituting the fixing type heat-sensitive sheet 309 is configured to be the same as the width of the light blocking protection sheet 303. . However, depending on the shape of the label constituting the fixing-type thermal sheet 309, the cross-sectional view in the width direction of the roll sheet 301 may be obtained by, for example, as shown in FIG. It is possible that the fixing type heat sensitive sheet 309 is shorter than the light blocking protective sheet.

  Next, the second die-cut type roll sheet 302 will be described. As shown in FIG. 15C and FIG. 16A, the second die-cut roll sheet 302 is a long light shielding protective sheet 303, which is long and die-cut to have a plurality of labels. The fixing type heat sensitive sheet 309 configured to be separable, the adhesive material 306 having the same shape as the long fixing type heat sensitive sheet 309, and the long release paper 307 are laminated in this order. . The fixing type thermal sheet 309 has a thermal recording layer 304 formed on one side of the substrate 305. Similar to the normal type roll sheet 300, the light blocking protective sheet 303 is adhered to the printing surface side (the thermal recording layer 304 side) of the fixing type thermal sheet 309, and the adhesive 306 is the printing side of the fixing type thermal sheet. The release paper 307 is adhered to the adhesive 306.

  FIG. 15C shows that labels formed by inserting slits 308 in a long fixing type heat-sensitive sheet 309 are arranged in the longitudinal direction of the roll sheet 302 with a predetermined interval. . In this figure, two labels are shown on the left and right. At this time, the width of the fixing type thermal sheet 309 and the width of the light blocking protection sheet 303 are configured to be the same length, and the adhesive is attached to the entire surface on the opposite side of the printing surface of the fixing type thermal sheet 309. Yes. The width of the release sheet 307 is larger than the width of the fixing type thermal sheet 309 and the light blocking protection sheet 303, and the fixing type thermal sheet 309 and the light blocking protection sheet 303 are arranged at the center in the width direction of the release sheet 307. Yes. Since the width of the fixing type thermal sheet 309 and the width of the release paper 307 are thus different, the release paper 307 can be easily peeled off from the fixing type thermal sheet 309.

  Next, with reference to FIG. 17, a roll sheet 3A having a fixing type heat sensitive sheet 309 and no release paper will be described. This type of roll sheet 3A is composed of two layers, a light blocking protection sheet 303 and a fixing type heat sensitive sheet 309 as a substrate. Like the roll sheets 300 to 302 having the release paper 307, the light blocking protection sheet 303 and the fixing-type heat sensitive sheet 309 can be peeled off and adhered so as not to be reattached.

  In the roll sheets 300 to 302 having the fixing type heat sensitive sheet 309 of this embodiment, the light blocking protection sheet 303 and the fixing type heat sensitive sheet have the same width, but as shown in FIG. The width of the blocking protection sheet 303 may be larger than the width of the fixing type heat sensitive sheet 309. In this figure, a fixing type heat sensitive sheet 309 is disposed at the center of the light blocking protection sheet 303 in the width direction. Further, as shown in FIG. 16C, the width of the light blocking protection sheet 303 may be made smaller than the width of the fixing type heat sensitive sheet 309. In this figure, a light blocking protection sheet 303 is disposed at the center in the width direction of the fixing type heat sensitive sheet 309. By making the width of the light blocking protection sheet 303 different from the width of the fixing heat sensitive sheet 309, the light blocking protection sheet 303 can be easily peeled off from the fixing heat sensitive sheet 309.

  Next, a manufacturing method of the roll sheets 300 to 302 having the fixing type heat sensitive sheet 309 will be described.

  First, the manufacturing method of the normal type roll sheet 300 will be described. As for the normal type roll sheet 300, (1-1) First, a fixing type thermal sheet 309 having a predetermined width is prepared. A thermal recording layer 304 is formed on one surface thereof. (1-2) An adhesive 306 is applied to the other surface side, and a release paper 307 having the same width as that of the fixing type heat sensitive sheet 309 is bonded via the adhesive 306. Thereby, the raw material of the adhesive tape with release paper is created. (1-3) An adhesive tape having a narrow width is produced by cutting out from the original fabric of this adhesive tape to the width of the release paper of the roll sheet 300. (1-4) The width of the adhesive tape 309 is a position that is a predetermined length away from each end in the width direction of the narrow adhesive tape, and reaches only the layers of the fixing type thermal sheet 309 and the adhesive 306 in parallel with the longitudinal direction of the tape. A half cut is applied to a narrow adhesive tape. The interval between the two half cuts is set so as to be the width of the fixing type thermal sheet 309 of the roll sheet 300. (1-5) Next, the fixing type heat-sensitive sheet at each end in the width direction of the narrow adhesive tape is removed.

  (1-6) On the other hand, a light blocking protective sheet 303 having the same width as the light blocking protective sheet of the roll sheet 300 is prepared, and a weak adhesive is applied to one surface thereof. (1-7) Then, the light blocking protection sheet and the fixing type heat-sensitive sheet 309 having a narrow adhesive tape are laminated via the weak adhesive applied to the light blocking protection sheet. (1-8) Then, the roll sheet 300 is manufactured by being pressed from above and making a small volume.

  With the above method, even if the width of the light blocking protection sheet 303 and the width of the fixing type heat sensitive sheet 309 as shown in FIG. Even if the width of the protective sheet 303 is larger than the width of the fixing type heat sensitive sheet 309, it can be freely handled.

  However, as shown in FIG. 16A, if the width of the light blocking protection sheet 303 and the width of the fixing type heat sensitive sheet 309 have the same dimensions, the following may be performed.

  (2-1) After creating a narrow adhesive tape according to (1-3) above, a light blocking protective sheet having the same width as the release paper 307 of the roll sheet 300 is prepared. (2-2) A weak adhesive in which a light-adhesive adhesive is applied to one surface of the light-blocking protective sheet, and the light-blocking protective sheet and the fixing type heat-sensitive sheet 309 having a narrow adhesive tape are applied to the light-blocking protective sheet. It is laminated through. (2-3) Then, it is pressed from above. (2-4) After that, a half cut is applied in parallel to the longitudinal direction of the tape at each end in the width direction of the pressure-sensitive adhesive tape on which the light blocking protective sheets are laminated so as to have the width of the light blocking protective sheet 303 of the roll sheet 300. Is done. (2-5) Next, the light shielding protective sheet and the fixing type heat sensitive sheet at each end in the width direction of the pressure-sensitive adhesive tape on which the light shielding protective sheets are laminated are removed. (2-6) Finally, the roll sheet 300 is manufactured by making a small volume of the adhesive tape on which the light blocking protective sheet is laminated.

  In the manufacturing method described above, in (1-3), after the original sheet of the pressure-sensitive adhesive tape with release paper is prepared, it is cut out to the width of the release paper of the roll sheet 300. Alternatively, an adhesive tape having the width of the release paper may be prepared and laminated with the release paper.

  Further, in the above manufacturing method, in (1-4), a half-cut is applied to the narrow adhesive tape so that only the layer of the fixing type thermal sheet 309 and the adhesive 306 reaches in parallel with the longitudinal direction of the tape. However, a fixing-type heat-sensitive sheet 309 and a release paper 307 having a width to be used in the target roll sheet 300 may be prepared in advance, and these may be laminated via an adhesive 306.

  Next, the manufacturing method of the roll sheet 301 which is the 1st die cut type is demonstrated. The manufacturing method of the roll sheet 301 which is the first die cut type is almost the same as the manufacturing method of the normal type roll sheet 300 described above. In (1-4), half-cutting is performed on the narrow adhesive tape so as to reach only the layer of the fixing type thermal sheet 309 and the adhesive 306 in parallel with the longitudinal direction of the narrow adhesive tape. In the roll sheet 302 which is the first die-cut type, instead, a half-cut is applied to a narrow adhesive tape so as to reach the desired label shape only by the fixing type heat-sensitive sheet 309 and the adhesive 306 layer. . In (1-5), the fixing type heat sensitive sheet at each end in the width direction of the narrow adhesive tape is removed. Instead of the first die-cut type roll sheet 301, the fixing type heat-sensitive sheet other than the desired label is removed. The only difference from the manufacturing method of the normal type roll sheet 300 is the above two points.

  A half cut other than the half cut for forming a desired label shape may be applied so that the fixing type heat sensitive sheet other than the label can be easily removed. For example, in the roll sheet 301, the fixing type heat sensitive sheet to be removed is connected in the width direction of the adhesive tape. Half-cutting may be performed in the longitudinal direction of the tape only in the portion of the fixing type thermal paper other than the label to be removed so that it is divided into two in the width direction of the narrow adhesive tape. Thereby, when removing parts other than a label, the situation where a label also peels off simultaneously can be reduced.

  Next, the manufacturing method of the roll sheet 302 which is a 2nd die cut type is demonstrated. The manufacturing method of the second die-cut type roll sheet 302 is almost the same as the manufacturing method of the normal type roll sheet 300 described above. In (1-4), half-cutting is performed on the narrow adhesive tape so as to reach only the layer of the fixing type thermal sheet 309 and the adhesive 306 in parallel with the longitudinal direction of the narrow adhesive tape. In the roll sheet 301 of the second die-cut type, in addition to that, a half-cut is applied to the narrow adhesive tape so that only the layer of the fixing type heat sensitive sheet 309 and the adhesive 306 reaches the desired label shape. Only the point is different. The slit 308 is formed by this half cut.

  Next, a manufacturing method of the roll sheet 3A having the fixing type heat sensitive sheet 309 shown in FIG. 17 and having no release paper will be described.

  (3-1) First, a fixing type thermal sheet 309 having a predetermined width is prepared. A thermal recording layer is formed on one side. (3-2) A light blocking protective sheet 303 having the same width as that of the fixing type heat sensitive sheet 309 is prepared, and a weak adhesive is applied on one surface thereof. (3-3) Then, the light blocking protection sheet 303 and the fixing type heat sensitive sheet 309 are laminated via weak adhesive applied to the light blocking protection sheet 303. (3-4) Then, it is pressed from above. (3-5) The sheet is cut out to a desired width from a sheet in which the fixing type heat sensitive sheet 309 and the light blocking protection sheet 303 are laminated. (3-6) The roll sheet 3A is manufactured by turning the cut laminated sheet into small rolls.

  In the first die-cut type roll sheet 301 and the second die-cut type roll sheet 302, the light shielding protective sheet is not half-cut, but as another embodiment, it is formed on a fixing type heat-sensitive sheet. The light shielding protective sheet may be half-cut at the same position and shape as the label. The reason why the light shielding protective sheet is not half-cut in the first die-cut type roll sheet 301 and the second die-cut type roll sheet 302 is as follows. When a series of printed matter is formed by printing on the roll sheet 301 or the roll sheet 302 and a plurality of labels are continuously formed, and then the plurality of labels are used, the light shielding protective sheet becomes dust, Just trash. However, if the light shielding protective sheet is half-cut, the number of dust increases accordingly. Further, although the fixing type heat sensitive sheet is covered with the light shielding protective sheet, it is covered with the light shielding protection sheet, so that there is a concern that the fixing type heat sensitive sheet may be exposed to light for some reason around the fixing type heat sensitive sheet.

  However, as an embodiment, when half-cutting is performed on the light blocking protection sheet in the same position and shape as the label formed on the fixing type thermal sheet, the release paper 307, the adhesive 306, the fixing type thermal sheet After laminating 309 and the light blocking protection sheet 303, only the light blocking protection sheet 303, the fixing type heat sensitive sheet 309 and the adhesive 306 can be half-cut at a time into a desired label shape. Furthermore, in the roll sheet 301, only the light blocking protection sheet 303, the fixing type heat sensitive sheet 309, and the adhesive 306 corresponding to portions other than the label are removed. As described above, when half-cutting is performed on the light blocking protective sheet, there is an advantage that the processing can be greatly simplified and the manufacturing cost can be reduced as compared with the case where the half-cutting is not performed.

  Next, a printing method for the roll sheet 3A having the fixing type heat sensitive sheet will be described. In the following explanation, mainly the case of the roll sheets 300 to 302 having the release paper 307 will be mainly described. However, even in the case of the roll sheet 3A having the fixing type thermal sheet 309 and no release paper, it is almost the same. does not change.

  As in the case of printing on a conventional roll sheet 3A having a general heat sensitive sheet, the roll sheet 3A having a fixing type heat sensitive sheet is held by a roll sheet holder 3. The roll sheet holder 3 is stored in the roll sheet holder storage section 4 of the label printer 1. Insert the leading end of the roll sheet 3A through the insertion opening 18 of the label printer 1 and pass it through the main body, set it so as to slightly protrude from the opposite side, and close the upper cover 5. At that time, the thermal head 31 passes through the insertion opening 18 of the label printer 1 with the light blocking protection sheet 303 side of the roll sheet 3A having the fixing type thermal sheet, that is, the printing surface side of the fixing type thermal sheet 309 facing downward. Is in contact with the light blocking protection sheet 303. As a result, the printing surface of the fixing type heat sensitive sheet 309 and the thermal head 31 face each other through the light blocking protection sheet 303.

  In this state, thermal printing is performed by transporting the heating elements of the thermal head 31 while selectively generating heat, and characters and designs are formed on the printing surface. After the printing is completed, the roll sheet 3 </ b> A having the fixing type thermal sheet is cut by the cutter unit 8 and then discharged from the label printer 1. Although the heat-printed characters and symbols are formed on the fixing-type heat-sensitive sheet 309 of the discharged roll sheet 3A, the user cannot check it by hiding the light-blocking protective sheet 303. Next, the user peels off the light blocking protection sheet 303 from the fixing type heat sensitive sheet 309. Thereby, characters and designs formed on the printing surface of the fixing type thermal sheet 309 can be confirmed. Moreover, the printed characters and designs are fixed by exposing the printing surface to light as it is.

  Further, in the roll sheets 300 to 302 having the release paper 307, the adhesive 306 attached to the fixing type thermal sheet 309 is exposed by peeling the release paper 307 from the fixing type thermal sheet 309. Therefore, the user can affix the fixing type heat sensitive sheet 309 to the object.

  In this way, printing can be performed on the roll sheet 3A having the fixing type thermal sheet in almost the same manner as when printing on the roll sheet 3A having the general thermal sheet while using the conventional label printer 1. Easy to use.

  There is a difference between a general heat-sensitive sheet and a fixing-type heat-sensitive sheet in the components of the heat-sensitive recording layer and the presence or absence of the light blocking protective sheet 303. At the time of printing, it is preferable that the color development of the general heat-sensitive sheet and the fixing-type heat-sensitive sheet be the same. Therefore, the roll sheet holder 3 holding the roll sheet 3 </ b> A having the general heat sensitive sheet and the roll sheet holder 3 holding the roll sheet 3 </ b> A having the fixing type heat sensitive sheet are separated from each other. It is determined by reading 60. As a result, the thermal print of the thermal head 31 is thermally printed at an optimum temperature. In the thermal printing, instead of changing the heat generation temperature of the thermal head 31 depending on whether it is a general heat sensitive sheet or a fixed heat sensitive sheet, the general heat sensitive sheet and the fixed heat sensitive sheet may be configured to have the same heat generation temperature. .

  The roll sheet 3A having the fixing type heat sensitive sheet 309 is configured by adhering the fixing type heat sensitive sheet 309 and the light blocking protection sheet 303 so as to be peelable. Therefore, after the roll sheet holder 3 holding the roll sheet 3A having the fixing type heat sensitive sheet 309 is mounted on the label printer 1 and subjected to heat printing, the light blocking protection sheet 303 is peeled off from the fixing type heat sensitive sheet 309 to thereby fix the fixing type heat sensitive sheet. By irradiating the sheet 309 with light, an image formed by heat printing can be fixed. Thereby, the fixing type heat-sensitive sheet 309 is easy to handle, but does not fade even when exposed to light for a long time. The fixing type thermal sheet 309 is easy to handle, for example, the label printer 1 has a light shielding structure, the roll sheet holder 3 has a light shielding structure, or a storage package for the roll sheet holder 3 is separately provided to have a light shielding structure. This means that it is not always necessary to pay close attention when mounting the roll sheet holder 3 on the label printer 1. Since the fixing type heat sensitive sheet 309 is easy to handle, the roll sheet holder 3 for holding it can be easily handled.

  Since the fixing-type heat-sensitive sheet 309 and the light blocking protection sheet 303 are detachably bonded by pressure bonding, the roll sheet 3A having the fixing-type heat-sensitive sheet 309 can be formed thinner than the case where the fixing-type heat sensitive sheet 309 and the light blocking protection sheet 303 are adhered to each other. In the heat printing, the presence / absence of heating is well transmitted and a clear image can be formed. Further, the roll sheet 3A having the fixing type heat sensitive sheet 309 is configured such that the fixing type heat sensitive sheet 309 and the light blocking protection sheet 303 cannot be re-adhered, so that they can be inadvertently re-adhered to each other or adhered to other places. It is easier to handle.

  Since the pressure-sensitive adhesive layer 306 and the release paper 307 covering the pressure-sensitive adhesive layer 306 are provided, the fixing type heat-sensitive sheet 309 can be attached to the object by peeling the release paper 307.

  Since the roll sheet 3A having the fixing type heat sensitive sheet 309 is roll paper, can the label printer 1 conventionally adapted to the roll sheet 3A having the general heat sensitive sheet be printed as it is on the roll sheet 3A having the fixing type heat sensitive sheet 309? The printer can be configured to print easily with only a small change in settings such as changing the temperature setting.

  By making the widths of the fixing-type heat-sensitive sheet 309 and the light-blocking protection sheet 303 different from each other, the light-blocking protection sheet 303 can be easily peeled off from the fixing-type heat-sensitive sheet 309.

  By making the width of the fixing type thermal sheet 309 larger than the width of the light blocking protection sheet 303, the light blocking protection sheet 303 can be easily peeled off from the fixing type thermal sheet 309.

  By making the width of the fixing type heat sensitive sheet 309 smaller than the width of the light blocking protection sheet 303, the light blocking protection sheet 303 can be easily peeled off from the fixing type heat sensitive sheet 309.

  By making the widths of the fixing type thermal sheet 309 and the release paper 307 different from each other, the release paper 307 can be easily peeled off from the fixing type thermal sheet 309.

  The width of the release paper 307 is larger than the width of the light blocking protection sheet 303, and the width of the light blocking protection sheet 303 is larger than the width of the fixing type heat sensitive sheet 309, so that the light blocking protection sheet 303 is peeled from the fixing type heat sensitive sheet 309. The paper 307 can be easily peeled off. At this time, since the width of the light blocking protection sheet 303 is larger than the width of the fixing type thermal sheet 309, the fixing type thermal sheet 309 can be used for full printing in the width direction. Further, since the width of the release paper 307 is larger than the width of the light blocking protection sheet 303, there is little possibility that the light blocking protection sheet 303 turns carelessly and the fixing type heat sensitive sheet 309 is exposed and the roll sheet 3A becomes unusable. Become.

  In the roll sheet 3A having the fixing type heat sensitive sheet 309, by making the fixing type heat sensitive sheet 309 into a plurality of labels, the label printer 1 conventionally adapted to the roll sheet 3A in which the general heat sensitive sheet is composed of a plurality of labels. Therefore, the fixing type heat sensitive sheet 309 can be printed as it is on the roll sheet 3A composed of a plurality of labels. Alternatively, it can be configured so that printing can be easily performed with only a small setting change such as changing the temperature setting.

  In the roll sheet 3A having the fixing-type heat-sensitive sheet 309, the fixing-type heat-sensitive sheet 309 is a long tape, and the general heat-sensitive sheet has conventionally been a long tape by cutting it into a predetermined shape in advance. Then, the label-type printer 1 corresponding to the roll sheet 3A previously cut into a predetermined shape allows the fixing-type heat-sensitive sheet 309 to be a long tape, and to the roll sheet 3A cut into a predetermined shape in advance. Can be printed as is. Alternatively, it can be configured so that printing can be easily performed with only a small setting change such as changing the temperature setting.
