Description

  The present invention relates to a tape for a tape printer used in a tape printer.

  Conventionally, various tape printers have been proposed that print characters and the like on a long sheet in which a release sheet is bonded to an adhesive sheet via a thermal head. In such a tape printer, a roll sheet wound around a core, a roll sheet holder to which the core is rotatably mounted, and each roll sheet holder having a plurality of types of sheet widths are arranged in the tape printer. And a support mechanism that is detachably supported, and a transport means for pulling and transporting the roll sheet from the roll sheet holder (see, for example, Patent Document 1).

  As an example of the roll sheet, the one shown in FIGS. 27 and 28 can be considered. 27 is a plan view of a state in which a part of the roll sheet 500 is expanded, and FIG. 28 is a rear view of the state in which a part of the roll sheet 500 is expanded. For example, the roll sheet 500 has a tape width of 66 mm, a recording medium 501 made of thermal paper on the surface, an adhesive layer on the back of the recording medium 501, and a release paper on the adhesive layer. 502 is peelably adhered. At both ends of the recording medium 501 in the tape width direction, the recording medium 501 is peeled off with a width of 2 mm, and cast portions 503 and 504 where the surface of the release paper 502 is exposed are formed. Since the cast portions 503 and 504 are formed, even if the adhesive oozes out from the adhesive layer of the recording medium 501, the adhesive does not reach the end in the width direction of the roll sheet 500, and the tape printer. No pressure-sensitive adhesive adheres to the transport path of the roll sheet 500, and there is no problem in transporting the roll sheet 500.

Further, as shown in FIG. 28, on the back surface of the release paper 502, sensor marks 505 that are rectangularly painted in black are continuously printed at predetermined intervals on one end in the width direction. By applying light to the sensor mark 505 from an optical sensor (not shown), it is possible to detect the feed amount of the roll sheet 500 and the roll sheet 500 being out of paper.

  Next, the optical sensor 95 will be described with reference to FIG. FIG. 15 is a partially enlarged view in which the vicinity of the platen roller 26 shown in FIG. 7 is enlarged. In the present embodiment, the optical sensor 95 is a reflective sensor, and the light from the light emitting portion of the optical sensor 95 is applied to the outer surface (second surface) of the release layer of the roll sheet 3A, and the reflected light is applied. A sensor mark received by a light receiving portion of an optical sensor 95 using a phototransistor or the like and printed on an outer surface (second surface) of a release layer of a roll sheet 3A to be described later, and a non-printing portion between the sensor marks; Is to read. As shown in FIG. 15, the optical sensor 95 is fixed to a frame portion 96 between the insertion port 18 and the platen roller 26, and is disposed so as to face the passage path of the roll sheet.

  Next, details of each example of the roll sheet 3A (corresponding to a tape for a tape printer), which is a main part of the present invention, will be described with reference to the drawings.

  (First Example) First, a roll sheet 300 which is a first example of the roll sheet 3A will be described with reference to FIGS. 16 is a plan view of a state in which a part of the roll sheet 300 is expanded, FIG. 17 is a rear view of the state in which a part of the roll sheet 300 is expanded, and FIG. It is.

  As an example, the roll sheet 300 has a tape width of 66 mm. 16 and 18, a recording medium 301 made of thermal paper is continuously provided in a tape shape on the surface of the roll sheet 300, and an adhesive layer 308 is provided on the back surface of the recording medium 301. A release paper 302 (corresponding to a release layer) is adhered to the adhesive layer 308 so as to be peelable. As an example of the pressure-sensitive adhesive layer 308, an acrylic emulsion-type pressure-sensitive adhesive can be used. Therefore, the roll sheet 300 has a three-layer structure. The roll sheet 300 is wound in a roll shape with the release paper 302 on the outside and the recording medium 301 on the inside, and the same applies to the other embodiments described below.

  Further, as shown in FIG. 16, at both ends of the recording medium 301 in the tape width direction (short direction of the recording medium 301), the recording medium 301 is peeled off with a width of 2 mm, respectively, and the surface of the release paper 302 (peeling off) Casting portions 303 and 304 are formed to expose (corresponding to the first surface of the layer). Since the cast portions 303 and 304 are formed, even if the adhesive oozes out from the adhesive layer of the recording medium 301, the adhesive does not reach the end in the width direction of the roll sheet 300, and the tape printer. No pressure-sensitive adhesive adheres to the transport path of the roll sheet 300, and the transport of the roll sheet 300 is not hindered.

  In addition, as shown in FIG. 17, the back surface of the release paper 302 (corresponding to the second surface of the release layer) is rectangular on one end side in the width direction of the roll sheet 300 (right side in FIG. 17). The sensor marks 305 filled in black are continuously printed in the longitudinal direction of the roll sheet 300 at a predetermined interval. As an example, the sensor mark 305 is a rectangle having a long side of 10 mm and a short side of 5 mm, and each sensor mark 305 is printed at a pitch of 10.16 mm.

  As shown in FIGS. 16 to 18, the sensor mark 300 is printed so as to avoid the back surface of the cast portion 304. Specifically, in this embodiment, since the width of the cast part 304 is 2 mm, the right end part (in FIG. 17) of the sensor mark 305 is one end part side in the width direction of the roll sheet 300 (in FIG. 17). It is printed at a position (as an example, 4.5 mm) that is 2 mm or more inside from the right side.

  A character 306 indicating the tape width and the like, which is identification information of the roll sheet 300, is printed at a position 6 mm inside from the left end portion (in FIG. 17) of the sensor mark 305. As this identification information, a tape type, a tape width, and the like are printed. If the recording medium 301 has a cut in a label shape, the size of the label is printed. Accordingly, since the character 306 as the identification information is printed 6 mm away from the sensor mark 305 that can take a large amount of ink, the printing of the character 306 does not become light.

  In the roll sheet 300 configured as described above, the sensor mark 305 is printed on the back surface of the release paper 302 so as to avoid the back surface of the cast portion 304. Therefore, the sensor mark 305 is applied to the back surface of the cast portion 304, and the sensor mark On the back side of 305, the thickness of the portion where the recording medium 301 exists and the portion which is the cast portion 304 are partially different, and the light reflectance and transmittance of the sensor mark 305 portion are non-uniform. Can be prevented. That is, when light is applied in the direction of arrow A shown in FIG. 18 by the optical sensor 95 that reads the sensor mark 305 (see FIG. 15), the light reflectance and transmittance of the sensor mark 305 become uniform. There is no error in reading the sensor mark. Similarly, it is possible to prevent the light reflectance and transmittance of the non-printed portion between the sensor marks 305 from becoming non-uniform, and an error does not occur when the optical sensor 95 reads the non-printed portion.

  (Second Embodiment) Next, a roll sheet 310 which is a second embodiment of the roll sheet 3A will be described with reference to FIGS. FIG. 19 is a plan view of a state in which a part of the roll sheet 310 is expanded, and FIG. 20 is a rear view of the state in which a part of the roll sheet 310 is expanded. Similarly to the roll sheet 300 of the first embodiment, the roll sheet 310 is provided with an adhesive layer on the back surface of the recording medium 311, and the release paper 312 (corresponding to the release layer) is adhered to the adhesive layer in a peelable manner. It has a three-layer structure. The difference between the roll sheet 310 and the roll sheet 300 of the first embodiment is that, as shown in FIG. 19, a plurality of recording media 311 are formed in a label shape in advance and are arranged at regular intervals. The recording medium 311 is obtained by making a cut in a label shape on a connected recording medium and peeling the surrounding recording medium (thermal paper).

  As an example, the roll sheet 310 has a tape width of 32 mm. As shown in FIG. 19, each recording medium 311 has a rectangular label shape with long 90 mm × 29 mm corners that are long in the longitudinal direction of the roll sheet 310, and the recording medium 311 has an interval of 6 mm and a cast portion. Each of 313 and 314 is formed by 1.5 mm. The recording medium (thermal paper) is also peeled off at the gap portion 319 between the recording medium 311 and the next recording medium 311 in the same manner as the cast portions 313 and 314.

  Further, as shown in FIG. 20, the back surface of the release paper 312 (corresponding to the second surface of the release layer) is rectangular on one end side in the width direction of the roll sheet 310 (right side in FIG. 20). A sensor mark 315 filled in black is printed. As an example, the sensor mark 315 is printed as a rectangle having a long side of 13 mm and a short side of 10 mm.

  As shown in FIGS. 19 and 20, the sensor mark 315 is printed so as to avoid the back surface of the cast part 314 and not to protrude from the back surface of the label-shaped recording medium 311. Specifically, in this embodiment, since the width of the cast part 314 is 1.5 mm, the right end part (in FIG. 20) of the sensor mark 315 is one end part side in the width direction of the roll sheet 310 (in FIG. 20). It is printed at a position (as an example, 4.5 mm) that is 1.5 mm or more inside from the right side in FIG.

  A character 316 indicating the tape width and the like, which is identification information of the roll sheet 310, is printed at a position 6 mm inside from the left end portion (in FIG. 20) of the sensor mark 315. As this identification information, the tape type, tape width, label size, and the like are printed. Accordingly, since the character 316 as identification information is printed 6 mm away from the sensor mark 315 that can take a large amount of ink, the printing of the character 316 does not become light.

  In the roll sheet 310 configured as described above, the sensor mark 315 is printed on the back surface of the release paper 312 so as to avoid the back surface of the cast portion 314 and not to protrude from the back surface of the label-shaped recording medium 311. Therefore, the sensor mark 315 is applied to the back surface of the cast portion 304 and the back surface of the interval portion 319, the thickness of the back side of the sensor mark 315 is partially different, and the light reflectance and transmittance of the sensor mark 315 portion are not uniform. Can be prevented. That is, when light is applied by an optical sensor 95 (see FIG. 15) that reads the sensor mark 315, the light reflectance and transmittance of the sensor mark 315 become uniform, so that the optical sensor 95 can read the sensor mark. There is no error. Similarly, the reflectance and transmittance of light in the non-printing area on the back surface of the label-shaped storage medium 311 between the sensor marks 315 are uniform, and an error may occur in reading the non-printing portion by the optical sensor 95. Absent.
