Description

  The present invention draws the label continuous body from the roll body in which the belt-like label continuous body is wound in a roll shape and separates it into individual labels, prints the label as necessary, and affixes the separated label The present invention relates to a portable label sticking machine used for sticking to a body, and more particularly to a portable label sticking machine that can be applied to a continuous label body without a mount (release paper).

  A conventional portable label applicator holds a roll body in which a continuous label body, in which a plurality of labels are temporarily attached on a mount, is wound in a roll shape, and feeds the continuous label body from the roll body to remove the label. The mount is turned at the part, and the individual labels are peeled off from the mount so that they can be attached to the adherend (see Patent Document 1). Therefore, after the label is attached, the mount is no longer necessary and is discarded, resulting in a waste of resources.

  Therefore, as described in Patent Document 2, a portable label sticking machine that can use a continuous label without a mount is required. By using a continuous label without a mount, resources are not wasted, and an environmentally friendly portable label applicator can be realized.

  For example, a continuous label without a mount is capable of separating individual labels by forming perforations (micro perforations) in the width direction at a predetermined interval on a belt-like label base material. Adhesive layers are provided in strips on both side edges, and a release agent layer (silicone oil layer, etc.) is provided in strips on a corresponding portion of the label substrate surface. The area between the agent layers is the printing area. Further, in order to accurately transfer the label continuous body, in the label base material, one or a plurality of transfer slits having an oval shape, for example, may be formed at the center of the perforation.

  The transfer roller for transferring such a label continuum is provided with a plurality of transfer claws that can be engaged with and disengaged from the transfer slit formed on the label base material at a predetermined angular interval. When rotated by an angle, the label continuum is transported a predetermined distance. Furthermore, in order to stably and continuously transfer the label continuum and to peel and affix the label, it is necessary to regulate the position in the width direction of the label continuum, and the label continuum with a mount is used. In the portable label sticking machine, the position restriction in the width direction of the label continuum is performed by a guide member arranged in a path along which the label continuum goes straight.

  However, when using a continuous label without a mount, the adhesive layer is exposed on the back of the continuous label, so that the adhesive gradually adheres to the guide member and the running of the continuous label becomes unstable. In addition, when the adhesion amount of the pressure-sensitive adhesive is large, there is a problem that the label continuum is stuck to the guide member and it becomes impossible to travel.

Japanese Utility Model Publication No. 55-150718 (Fig. 2) JP 2004-299757 A (paragraph 0003)

  Therefore, in view of the above points, the present invention makes it difficult for the adhesive on the back surface of the label to adhere to the guide member that regulates the position in the width direction of the label continuous body even when using a label continuous body without a mount. It is an object of the present invention to provide a portable label sticking machine that can stably and continuously transfer a continuous body and peel and stick a label.

  In order to solve the above problems, a portable label sticking machine according to one aspect of the present invention is a continuous label in which perforations are formed in the width direction at predetermined intervals and an adhesive layer is provided on one surface. It is a portable label applicator used to separate the body into individual labels and attach the separated labels to the object to be attached, holding the roll body in which the label continuous body is wound into a roll A mechanism and a pair of guide members for restricting the position in the width direction of the label continuum from both sides, and when the label continuum is loaded on the opposing surfaces of the pair of guide members, Inclination for guiding to a predetermined position is provided, and a transfer roller that pulls and transfers the label continuous body from the roll body held by the holding mechanism, and an operation lever that is rotatable with respect to the grip provided on the housing Including A transfer mechanism that includes an operation mechanism that rotates the transfer roller in accordance with the rotation of the producing lever and a transfer belt that is driven in accordance with the rotation of the transfer roller, and that transfers the continuous label fed from the transfer roller in a predetermined direction. And a cutting mechanism for cutting the label continuum on the transfer belt along the perforation as the operation lever rotates.

  According to one aspect of the present invention, a pair of guide members for regulating the position of the label continuous body in the width direction from both sides are provided on the transfer roller, and the label continuous body is provided on the opposing surfaces of the pair of guide members. By providing an inclination to guide the label continuum to a predetermined position when loading the label, it is difficult for the adhesive on the back of the label to adhere to the guide member, and the label continuum can be transported and the label peeled and pasted stably And can be enabled continuously.

FIG. 1 is a side view showing a state in which one side plate of a portable label sticking machine according to an embodiment of the present invention is removed. The portable label sticking machine 1 draws the label continuous body 3 from the roll body in which the strip-shaped continuous label body 3 is wound in a roll shape, separates it into individual labels 3a, and performs printing on the label 3a as necessary. The label 3a is used for attaching the separated label 3a to an adherend (not shown), and is particularly applicable to a continuous label body without a mount (release paper).

  As shown in FIG. 1, the portable label sticking machine 1 includes a pair of left and right side plates 2 constituting a housing, a holding mechanism 4 that holds a roll body in which a label continuous body 3 is wound in a roll shape, An operation lever 5, a platen unit 6, a printer 7, a label cutting mechanism 8, and a pasting roller 9 are included.

  The holding mechanism 4 rotates around a holder shaft 13 provided on the side plate 2 so as to be openable and closable with respect to the side plate 2 and a label holding provided inside the holder cover 14. A roll body including the shaft 15 and having the label continuous body 3 wound in a roll shape can be loaded and held on the label holding shaft 15.

  A pair of left and right side plates 2 is integrally provided with a grip 10 that can be gripped by an operator. The operation lever 5 is attached to the grip 10 so as to be rotatable around a lever shaft 11. An arbitrary urging member, for example, a coil spring 12, is provided between the operation lever 5 and the grip 10, and the operation lever 5 is attached to the grip 10 in a separated state when released as shown in FIG. It is possible.

  The operator drives the platen unit 6, the printer 7, and the label cutting mechanism 8 by gripping and releasing the operation lever 5 together with the grip 10 against the urging force of the coil spring 12, and then pasting. Using the roller 9, an operation of attaching the single-leaf label 3 a separated from the label continuous body 3 to the adherend is performed.

  The platen unit 6 is a transport mechanism that transports the label continuous body 3 in the direction of the affixing roller 9 as the operation lever 5 rotates. The label 3 a is sent out from the tip (left end in the figure), and the label is applied by the affixing roller 9. 3a can be affixed to a to-be-adhered body.

  FIG. 2 is an exploded perspective view of the platen unit shown in FIG. The platen unit 6 includes a platen frame 18, a transfer roller 19, and a pressing element 20, and the transfer roller 19 and the pressing element 20 can contact and separate from each other.

  The platen frame 18 is attached to the casing so as to be opened and closed with respect to the casing by rotating around the platen opening / closing shaft 21. A pair of engagement / disengagement rollers 26 are formed on the left and right sides of the front end side of the platen frame 18 so as to be able to engage / disengage with an opening / closing engagement / disconnection piece connected to an opening / closing knob 49 (FIG. 1). It has become. By operating the opening / closing knob 49 to open / close the entire platen unit 6 with respect to the housing, the label continuous body 3 shown in FIG. 1 can be inserted between the transfer roller 19 and the pressing element 20 and loaded. It becomes possible.

  The transfer roller 19 is attached to an opening formed in the platen frame 18 so as to be rotatable around a roller shaft 27, and rotates in contact with the surface (release agent layer) of the label continuous body 3, thereby holding mechanism 4. The label continuous body 3 is pulled out from the roll body held in (FIG. 1) and transferred.

  In the label continuous body 3, when one or a plurality of transfer slits are formed in the central portion of the micro perforation, the transfer rollers 19 are provided with one or more rows of transfer claws 33 at a predetermined pitch. It may be provided. These transfer claws 33 can be engaged with and disengaged from the transfer slit of the label continuous body 3. In the example shown in FIG. 2, a central circumferential groove 32 is formed between the circumferential portions provided with two rows of transfer claws 33, and a pair of left and right outer sides are formed on both sides of the circumferential portions. A circumferential groove 34 is formed.

  FIG. 3 is a perspective view of main parts of the operation lever and the platen unit shown in FIG. The operation lever 5 has a bifurcated yoke portion 5a on the tip side, and the printer 7 (FIG. 1) is attached to the yoke portion 5a. In addition, a transfer rotation claw 30 is attached to the connection shaft 29 of the connection arm 28 extending below the lever shaft 11 in the operation lever 5 so as to be able to reciprocate. The transfer rotation claw 30 is urged upward in the figure, and can be engaged with and disengaged from each of the plurality of transfer protrusions 31 provided radially on the side surface of the roller gear 25 in the transfer roller 19. Rotate. The operation lever 5 and the connecting arm 28 to the transfer projection 31 together with the grip 10 to the coil spring 12 shown in FIG. 1 constitute an operation mechanism that drives the platen unit 6 and the like as the operation lever 5 rotates.

  The platen unit 6 includes a drive gear 22, a driven gear 23, and a transfer endless belt 24 that is wound around the drive gear 22 and the driven gear 23. The driving gear 22 to the transfer endless belt 24 constitute a transfer mechanism that transfers the label continuous body 3 supplied from the transfer roller 19 in a predetermined direction. When the drive gear 22 engages with the roller gear 25 of the transfer roller 19, the transfer endless belt 24 is driven as the transfer roller 19 rotates. The transfer endless belt 24 contacts the back surface (adhesive layer) of the label continuum and transfers the label continuum.

  Here, when the operator holds the operation lever 5 together with the grip 10 (FIG. 1), the operation lever 5 rotates from the first position (lower side in the figure) to the second position (upper side in the figure). To do. As a result, the transfer rotation claw 30 connected to the connection arm 28 via the connection shaft 29 is another transfer protrusion 31 adjacent to the left side of the one transfer protrusion 31 that has been engaged so far. Will come into engagement.

  Further, as the operation lever 5 rotates, the label cutting mechanism 8 (FIG. 1) cuts the label continuous body on the transfer endless belt 24 along the micro perforation, and the single-leaf label is removed from the label continuous body. To separate. Further, the printer 7 (FIG. 1) attached to the yoke portion 5a performs imprinting on the single-leaf label separated from the label continuous body.

  On the other hand, when the operator releases the operation lever 5 from the grip, the operation lever 5 rotates from the second position to the first position, and is connected to the connection arm 28 via the connection shaft 29. The moving claw 30 pushes the engaged transfer protrusion 31. Thereby, the transfer roller 19 rotates around the roller shaft 27 by a predetermined angle, and the continuous label body is pulled out from the roll body held by the holding mechanism 4 (FIG. 1) and transferred. Further, since the drive gear 22 rotates via the roller gear 25, the transfer endless belt 24 is driven by a predetermined distance, and the label continuous body supplied from the transfer roller 19 is transferred in a predetermined direction.

  Since the back surface (adhesive layer) of the transferred label continuum is in contact with the surface of the transfer endless belt 24, the transfer endless belt 24 is made of silicone or fluorine rubber having non-adhesive properties. Alternatively, it is desirable to apply a release agent or the like to the surface of the transfer endless belt 24. Further, since the transfer endless belt 24 also serves as a cradle for the stamping operation on the label continuum by the printer 7, the transfer endless belt 24 is disposed inside the transfer endless belt 24 facing the printer 7 in the platen frame 18 (FIG. 2). A pressure receiving plate may be arranged.

  FIG. 4 is a diagram illustrating a positional relationship between the transfer roller and the label continuum. As shown in FIG. 4, in the continuous label body 3, micro perforations 3b are formed in the width direction at predetermined intervals so that the individual labels 3a can be separated. In this example, two transfer slits 3 c are formed at the center of the micro perforation 3 b in the label continuous body 3 in order to accurately transfer the label continuous body 3.

  On the other hand, the transfer roller 19 protrudes from the reference surface 19a and the reference surface 19a that contacts the surface (release agent layer) of the label continuous body 3 at a predetermined distance R1 from the center of the rotation shaft (roller shaft 27) of the transfer roller 19. The transfer claw 33 is detachable from the transfer slit 3c formed in the label continuous body 3. An adhesive layer is provided on the back surface of the label continuum 3. When the transfer slit 3c is not formed in the label continuous body 3, the transfer claw 33 may be omitted.

  Further, the transfer roller 19 includes a pair of guide members 91 and 92 for regulating the position of the label continuous body 3 in the width direction (Z-axis direction) from both sides. The opposing surfaces of the pair of guide members 91 and 92 are provided with slopes 91a and 92a for guiding the label continuous body 3 to a predetermined position when the label continuous body 3 is loaded.

  Here, the distance between the opposing surfaces of the pair of guide members 91 and 92 is constant at least at distances R1 to R2 from the center of the roller shaft 27, and at least at the distances R2 to R3 from the center of the roller shaft 27. You may make it expand with the increase in the distance from the center of (R1 <R2 <R3). In the example shown in FIG. 4, the guide member 92 is provided with an inclination 92a at distances R2 to R3 from the center of the roller shaft 27, and the guide member 91 is provided with an inclination 91a at distances R2 to R4 from the center of the roller shaft 27. (R3 <R4).

  According to the above configuration, when the label continuous body 3 is rotated and transferred by the rotation of the transfer roller 19, the guide members 91 and 92 also rotate together with the label continuous body 3. And 92. In addition, since tension acts in the direction in which the label continuous body 3 is separated from the transfer roller 19 on the upstream side and the downstream side in the transport direction of the transfer roller 19, the adhesive of the label continuous body 3 adheres to the guide member 91 or 92. Even in this case, the label continuous body 3 is forcibly peeled off from the guide member 91 or 92. Therefore, the label continuous body 3 can be stably conveyed. Moreover, since the surface (release agent layer) of the label continuous body 3 is in contact with the reference surface 19a of the transfer roller 19, the adhesion amount of the adhesive to the guide members 91 and 92 can be reduced.

  Referring to FIG. 2 again, the pressing element 20 includes an element frame 35, two pairs of upper, lower, left and right backup rollers 36, a pair of left and right backup rings 37 located inside the backup roller 36, a torsion coil spring 38, and left and right A pair of leaf springs 39 is included.

  The element frame 35 is provided on the support frame 41, a pair of left and right support frames 41 facing the circumference of the transfer roller 19, a pair of left and right widening frames 42 projecting outward from the support frame 41, and the support frame 41. And a pair of upper and lower rotating shafts 43 for mounting the backup roller 36 and the backup ring 37. The torsion coil spring 38 allows the transfer roller 19 to be separated from the pressing element 20 and allows a gap to be inserted between them so that the label continuous body can be inserted.

  FIG. 5 is a side view showing a state in which the platen unit is closed with respect to the housing. When the platen unit 6 is closed with respect to the housing, the transfer roller 19 and the pressing element 20 are pressed against each other. At that time, the backup roller 36 and the backup ring 37 (FIG. 2) press the label continuous body against the transfer roller 19 side.

  Here, since the backup roller 36 and the backup ring 37 are in line contact with the back surface (adhesive layer) of the label continuum, the adhesive force with the adhesive layer can be minimized and a pair of left and right leaf springs can be used. 39 allows pressing with a predetermined spring elasticity. Note that the backup roller 36 and the backup ring 37 are preferably made of silicone or fluorine rubber having non-adhesive properties, or have a release agent or the like applied to the surface.

  As the backup ring 37 rotates along the outer circumferential groove 34 formed in the transfer roller 19, the label continuous body is sandwiched between the transfer roller 19 and the pressing element 20. Further, the transfer claw 33 of the transfer roller 19 is engaged with the transfer slit from the surface side of the label continuous body, and the label continuous body is fed onto the transfer endless belt 24 by the rotation of the transfer roller 19.

  FIG. 6 is a side view showing a state in which the platen unit is opened with respect to the housing. When the platen unit 6 is opened with respect to the housing, the transfer roller 19 is separated from the pressing element 20, and a gap 40 for introducing the label continuous body 3 is formed therebetween.

  The widening frame 42 fixed to the support frame 41 is attached so as to be rotatable around an element shaft 47 provided on the outer wall surface of the platen frame 18, and the platen frame 18 is relatively moved with respect to the pressing element 20. It can be rotated.

  The torsion coil spring 38 is rotatably supported by a spring mounting shaft 44 provided on the outer wall surface of one support frame 41, and the first spring receiver 45 provided on the inner wall surface of the platen frame 18 and the one side Both ends of the platen frame 18 are urged against the pressing element 20 in a released state (FIG. 6) by contacting both ends with the second spring support 46 provided on the support frame 41.

  The leaf spring 39 is attached to the back surface of the support frame 41 opposite to the transfer roller 19 and cooperates with the torsion coil spring 38 by contacting the lever shaft 11 (FIG. 3) of the operation lever. Then, the platen frame 18 is urged in a direction to be in a released state (FIG. 6) with respect to the housing.

  FIG. 7 is a perspective view of the operation lever and the label cutting mechanism shown in FIG. FIG. 8 is an exploded perspective view of the label cutting mechanism shown in FIG. FIG. 9 is an assembly view of the label cutting mechanism shown in FIG. As shown in FIG. 8, the label cutting mechanism 8 includes a cutting piece 51 and an interlocking mechanism 52.

  The cutting piece 51 cuts the label continuous body by reciprocating along the micro perforation and / or the transfer slit in the width direction of the label continuous body transferred on the transfer endless belt 24. Separate into single leaf labels. As a material of the cutting piece 51, it is desirable to have predetermined rigidity and non-adhesiveness. For example, a resin such as polyacetal (POM), or a silicone or a fluorine-based coating agent (release agent) is applied as necessary. A resin such as polycarbonate (PC) or acrylonitrile / butadiene / styrene (ABS) may be used.

  As shown in FIGS. 7 to 9, the interlocking mechanism 52 includes a vertical rail member (first rail member) 53 fixed to the side plate 2 (FIG. 1), a connection plate 54, a link bar 55, and a burster. A bracket 56 and a lateral rail member (second rail member) 57 are included.

  The vertical rail member 53 is fixed to the inner wall surface of one side plate 2 (FIG. 1), and a vertical guide groove 58 is formed at the center thereof, and the connecting plate 54 can reciprocate up and down in the vertical guide groove 58. It is assembled to. The connection plate 54 has a connection pin 60 that is fitted into a yoke connection hole 59 formed in one yoke portion 5 a of the operation lever 5 shown in FIG. 7, and is connected to the vertical rail member 53 in conjunction with the operation lever 5. Reciprocate along. In addition, a link connecting hole 61 is formed in the connecting plate 54, and the connecting pin 62 of the link bar 55 is fitted into the link connecting hole 61 so that the driving force from the operation lever 5 (yoke portion 5a) is linked. It is transmitted to the bar 55.

  The link bar 55 is provided with a pair of left and right bracket connecting pins 63 at the end opposite to the connecting pins 62. The link bar 55 is connected between the connection plate 54 and the burster bracket 56, and is in a posture inclined with respect to the vertical rail member 53 and the horizontal rail member 57 in accordance with the reciprocation of the connection plate 54. The star bracket 56 is reciprocated.

  The burster bracket 56 includes a bracket body 64, a pair of left and right fulcrum pins 65, a pair of left and right posture regulating pins 66, and a pair of left and right elastic protrusions 67, and the transfer endless belt 24 (FIG. 2). It can reciprocate along the width direction. A cutting piece 51 is rotatably attached to the burster bracket 56.

  A bar connecting hole 68 is formed in the bracket main body 64 shown in FIG. 8, and the bracket connecting pin 63 of the link bar 55 is fitted into the bar connecting hole 68 so that the link bar 55 is connected to the bracket main body 64. . Therefore, by moving the link bar 55 in an inclined state with respect to the vertical rail member 53 and the horizontal rail member 57, the cutting piece 51 can be reciprocated in the width direction of the label continuous body together with the burster bracket 56.

  The horizontal rail member 57 is disposed at a right angle to the vertical rail member 53 along the width direction of the transfer endless belt 24 so as to be positioned above the transfer endless belt 24 (FIG. 2). The horizontal rail member 57 is formed with a guide window 69 for guiding the fulcrum pin 65 and the posture regulating pin 66 of the burster bracket 56 on the left and right wall surfaces.

  The guide window 69 guides the burster bracket 56 in the width direction of the label continuous body and restricts the operation range thereof. The fulcrum pin 65 and the attitude regulating pin 66 are movable along a guide window 69 formed in the horizontal rail member 57. The posture regulating pin 66 is in contact with or separated from the upper inner wall surface 69a or the lower inner wall surface 69b of the guide window 69, and the posture of the burster bracket 56, that is, the contact / separation posture (pressing and separation) of the cutting piece 51 with respect to the label continuous body. regulate. As shown in FIG. 9, a posture control window 70 is formed on the bottom surface of the horizontal rail member 57 along the width direction of the transfer endless belt 24 (FIG. 2).

  FIG. 10 is a side view of the cutting piece and the interlocking mechanism in a state where the operation lever is gripped and cutting of the label continuous body is started. 11 is a view for explaining the cutting operation of the cutting piece and the interlocking mechanism shown in FIG. 10, FIG. 11A is a side view of the main part of the cutting piece and the interlocking mechanism, and FIG. It is an enlarged front view of a cutting piece and a transfer endless belt. 12 is a view for explaining the return operation of the cutting piece and the interlocking mechanism shown in FIG. 10, FIG. 12A is a side view of the main part of the cutting piece and the interlocking mechanism, and FIG. It is an enlarged front view of a cutting piece and a transfer endless belt.

  By holding the operation lever 5 together with the grip 10 shown in FIG. 1, the label continuous body 3 is cut by the label cutting mechanism 8. In a state where the operation lever 5 is released, the coupling plate 54 is positioned at the uppermost position in the vertical guide groove 58 of the vertical rail member 53 in the interlocking mechanism 52 by the force of the coil spring 12 pulling up the yoke portion 5a. Accordingly, as shown in FIG. 12, the Burster bracket 56 connected to the connecting plate 54 via the link bar 55 is slightly rotated counterclockwise around the fulcrum pin 65, and the attitude regulating pin 66 is laterally moved. The cutting piece 51 is in contact with the upper inner wall surface 69 a of the guide window 69 of the rail member 57 and is slightly separated from the surface of the label continuous body 3.

  When the operating lever 5 is gripped together with the grip 10, the driving force (arrow A1) from the yoke portion 5a is transmitted from the connecting plate 54 to the link bar 55 as shown in FIG. As a result, the posture regulating pin 66 is slightly rotated clockwise around the fulcrum pin 65 (arrow A2) and comes into contact with the lower inner wall surface 69b. Therefore, the cutting piece 51 is lowered to a level position where the cutting piece 51 can enter below the continuous label body 3 on the transfer endless belt.

  At this time, as shown in FIG. 10, the cutting piece 51 is located slightly to the left of the left edge portion of the label continuous body 3 in the drawing. By further gripping the operation lever 5, the cutting piece 51 moves to the right from this state, so that the cutting piece 51 cuts into the side surface of the label continuous body 3.

  When the operation lever 5 is further gripped, the connection plate 54 is further lowered by transmission of the driving force from the operation lever 5, and the driving force is transmitted to the burster bracket 56 via the link bar 55. Accordingly, as shown in FIG. 11, the Burster bracket 56 moves toward the right end of the guide window 69 of the lateral rail member 57, and the cutting piece 51 moves along the transverse recess 24 a of the transfer endless belt 24. .

  The circumferential tip 51a of the cutting piece enters the transverse recess 24a of the transfer endless belt 24 while applying a predetermined pressing force to the edge portion of the label continuous body 3, and extends to the edge portion of the label continuous body 3. The label continuum 3 is broken sequentially from the end of the existing perforation. As a result, the label continuous body 3 can be cut with a relatively small force to separate the label continuous body 3 into single-leaf labels.

  Since the transverse recess 24a of the transfer endless belt 24 is formed relatively thin in accordance with the shape of the circumferential tip 51a of the cutting piece 51, the circumferential tip 51a and the micro perforation of the label continuous body 3 Even if the relative position slightly deviates, the micro perforation of the label continuous body 3 or the vicinity thereof can enter the transverse recess 24a. Therefore, the cutting operation as described above can be performed accurately.

  With the operating lever 5 fully gripped, the cutting piece 51 completes the cutting of the label continuous body 3, and the coil spring 12 (FIG. 1) acts on the connecting plate 54 as the operating lever 5 is released. Due to the force, the cutting piece 51 begins to separate from the label continuous body 3.

  When the operation lever 5 is released, the link bar 55 is pulled up by the connecting plate 54. As a result, as shown in FIG. 12, the Burster bracket 56 rotates counterclockwise around the fulcrum pin 65, the attitude regulating pin 66 contacts the upper inner wall surface 69 a of the guide window 69, and the cutting piece 51 Is raised from the surface of the label continuum 3. As the operating lever 5 is released, the connecting plate 54 and the link bar 55 return upward, and the burster bracket 56 returns to its original position.

  In the process of releasing the operation lever 5, the continuous label body 3 is transferred by a predetermined angle by the transfer roller 19, and the continuous label body 3 is transferred by a predetermined distance by the transfer endless belt 24. Therefore, during the movement of the label continuum 3, the cutting piece 51 does not contact or interfere with the label continuum 3 so that the transfer of the label continuum 3 is not hindered.

  However, due to a slight timing difference between the cutting operation and the transfer operation of the label continuous body 3 due to the gripping and releasing of the operation lever 5, the cutting piece 51 is engaged with the transverse recess 24a of the label continuous body 3 or the transfer endless belt 24. Even if the label continuum 3 is transferred in a state where the tape is continuous, the taper shape of the circumferential tip 51a of the cutting piece and the taper shape of the transverse recess 24a of the transfer endless belt 24 are almost the same inclined surface. (See FIG. 12B), the cutting piece 51 is separated upward from the transverse recess 24a of the transfer endless belt 24 without stopping the transfer of the label continuous body 3. can do.

  Referring again to FIG. 1, the printer 7 is attached to the tip end side of the bifurcated yoke portion 5 a of the operation lever 5. When the operator holds the operation lever 5 together with the grip 10, the printer 7 also Rotate. As a result, ink is applied to the type portion 7a of the printer 7 by the ink roller 48, and the type portion 7a comes into contact with the label 3a which is attached to the upper surface of the transfer endless belt 24 and transferred to the label 3a. Predetermined information is printed. Here, the printer 7 and the ink roller 48 constitute a printing mechanism that performs printing on the label 3 a on the transfer endless belt 24. In addition, when using the label continuous body 3 which has already been printed, it is not necessary to print on the label 3a, and therefore printing can be omitted by removing the printer 7 or the like.

  The pasting roller 9 is located at the lower end of the front end of the casing of the portable label pasting machine 1 (lower left end in FIG. 1), and a part of its circumference is exposed to the outside of the casing. The endless belt 24 comes into contact with the label 3a conveyed to the tip end portion of the platen unit 6. When the operator performs a pasting operation of pressing the label 3a on the pasting roller 9 against the body to be pasted, the label 3a is pressed and pasted to the body to be pasted by the pasting roller 9.
