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 can separate individual labels by forming cuts such as perforations and slits in the width direction at a predetermined interval on a strip-shaped label substrate. Adhesive layers are provided in strips on both left and right edges, and release agent layers (silicone oil layers, etc.) are provided in strips on a substantial portion of the label substrate surface. The area between the release agent layers is the printing area. Below, the case where the perforation is formed as a cutting part in a label continuum is explained. Further, in order to accurately transport the label continuous body, for example, one or a plurality of transport slits having an oval shape may be formed in the cut portion of the label continuous body.

  The portable label applicator is provided with an operation lever that can be rotated within a predetermined angle range with respect to the grip provided on the housing, and the transport mechanism moves the label continuum along with the rotation of the operation lever. When the label continuous body is transported and stopped, a label cutting mechanism (also referred to as a Burster mechanism or a cutter mechanism) cuts the label continuous body and separates into individual labels.

  For example, the transport mechanism includes a transfer roller and a transfer belt. The transfer roller 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, and the transfer roller rotates to transfer the label continuous body to the transfer belt. Move up. The transfer belt contacts the back surface (adhesive layer) of the label continuum to transfer the label continuum in a predetermined direction.

  The label cutting mechanism includes a cutting piece that moves in the width direction of the transfer belt and the label continuous body, and the cutting piece moves across the label continuous body on the transfer belt so that the label continuous body is moved along the perforation. Cut and separate the single leaf label from the label continuum.

  In order to facilitate the cutting of the label continuous body, guide grooves extending in the width direction are formed on the outer peripheral surface of the transfer belt at a predetermined pitch in the longitudinal direction. Therefore, in order to cut the label continuous body satisfactorily by the label cutting mechanism, the transfer belt and the perforation of the transfer belt and the circumferential tip of the cutting piece are aligned in a straight line. It is necessary to stop the label continuum.

  However, depending on the dimensional accuracy or mounting accuracy of the transfer belt or other parts, the stop position of the guide groove of the transfer belt may deviate from the position of the circumferential tip of the cutting piece. In such a case, the cutting piece rides on the convex portion between the guide groove of the transfer belt, or the cutting piece is in the guide groove adjacent to the guide groove corresponding to the position of the perforation of the label continuous body. Sometimes it gets in. As a result, there is a problem that the label continuum cannot be cut along the perforation and malfunction occurs.

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

  Therefore, in view of the above points, when using a continuous label without a backing sheet, the present invention provides a transfer even if the stop position of the guide groove of the transfer belt deviates to some extent from the position of the circumferential tip of the cutting piece.

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 affixing the label 3a to an adherend (not shown), and is particularly applicable to a continuous label without a mount (release paper).

  As shown in FIG. 1, the portable label applicator 1 includes a pair of left and right side plates 2 (only one side plate is shown in FIG. 1) and a label continuous body 3 that are wound in a roll shape. A holding mechanism 4 that holds the rotated roll body, an operation lever 5, a platen unit 6, a printer 7, a label cutting mechanism 8, and a sticking roller 9 are included.

  The holding mechanism 4 includes a holder cover 14 attached to the side plate 2 so as to be openable and closable by rotating around a holder shaft 13 provided on the side plate 2, and a label holding shaft provided inside the holder cover 14. 15, and a roll body in which the label continuous body 3 is 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 the lever shaft 11 within a predetermined angle range. 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 continuum 3 in the direction of the affixing roller 9 as the operation lever 5 rotates. The label 3a is sent out from the tip (left end in the figure), and the affixing roller 9 labels the label 3a. Can be attached to the object to be attached.

  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 platen frame 18 and the transfer roller 19 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.

  When one or more transfer slits are formed in the cut portion of the label continuous body 3, the transfer roller 19 may be provided with one or more rows of transfer claws 33 at a predetermined pitch. . 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 circles 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. Further, a transfer rotation claw 30 is attached to a connection shaft 29 of a 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 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 plurality of gears or rollers including at least one gear driven by an operation mechanism (in the drawing, the driving gear 22 and the driven gear 23 are shown), and around these gears or rollers. And an endless belt for transfer (transfer belt) 24 wound around.

  The transfer endless belt 24 has an inner peripheral surface in which inner teeth engaging with the drive gear 22 are formed at a predetermined pitch in the longitudinal direction, and a guide groove (transverse recess) extending in the width direction in the longitudinal direction. The label continuum drawn from the roll body by the transfer roller 19 is transferred.

  The guide groove of the transfer endless belt 24 is formed to facilitate the cutting of the label continuous body by the cutting piece (burster roller) of the label cutting mechanism 8 (FIG. 1). Further, in the transfer endless belt 24, it is desirable that the recesses of the inner teeth on the inner peripheral surface and the guide grooves on the outer peripheral surface are formed at corresponding positions (in the same phase).

  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. Instead of the driven gear 23, a cylindrical roller may be used.

  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). . 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 in the drawing. 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 perforation (micro perforation). Separate labels. 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 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.

  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. 4 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 (FIG. 2) of the transfer roller 19 engages 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. 5 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, The platen frame 18 is urged toward the pressing element 20 in a released state (FIG. 5) by having both ends abutting against a second spring receiver 46 provided on one 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 biased with respect to the housing in a direction to be in a released state (FIG. 5).

  FIG. 6 is a perspective view of the operation lever and the label cutting mechanism shown in FIG. FIG. 7 is an exploded perspective view of the label cutting mechanism shown in FIG. FIG. 8 is an assembly view of the label cutting mechanism shown in FIG. As shown in FIG. 7, the label cutting mechanism 8 includes a cutting piece 51 and an interlocking mechanism 52, and on the outer peripheral surface of the transfer endless belt 24 (FIG. 2) as the operation lever 5 rotates. By pressing the cutting piece 51 against the label continuous body and moving the cutting piece 51 along the guide groove of the endless belt 24 for transfer, the label continuous body is cut along the micro perforation and separated 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. 6 to 8, the interlocking mechanism 52 includes a vertical rail member (first rail member) 53, a connecting plate 54, a link bar 55, a burster bracket 56, and a horizontal rail member (second rail). Rail member) 57.

  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. 6, 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 pin 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. 7, 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. Further, as shown in FIG. 8, 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).

  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 order to facilitate the cutting of the label continuous body 3, as shown in FIG. 9, a guide groove extending in the width direction of the transfer endless belt 24 is formed on the outer peripheral surface (upper side in the drawing) of the transfer endless belt 24. 24 a is formed at a predetermined pitch in the longitudinal direction of the transfer endless belt 24. 9 to 11 show a case where the pressure receiving plate 16 is disposed behind the transfer endless belt 24.

  In order to cut the label continuous body 3 satisfactorily by the label cutting mechanism, as shown in FIG. 9, the guide groove 24a of the transfer endless belt 24, the micro perforation 3b of the label continuous body 3, and the cutting piece 51 It is necessary to stop the transfer endless belt 24 and the label continuous body 3 so that the circumferential front end portion 51a is aligned on a straight line.

  However, depending on the dimensional accuracy or mounting accuracy of the transfer endless belt 24 or other parts, the stop position of the guide groove 24a of the transfer endless belt 24 may be at the circumferential tip 51a of the cutting piece 51 as shown in FIG. There is a case where the position is shifted to the right side (FIG. 10A) or the left side (FIG. 10B). In such a case, the cutting piece 51 may run on the convex portion between the guide groove of the transfer endless belt 24, and the continuous label body 3 may not be cut well.

  When the stop position of the transfer endless belt 24 is further shifted, the cutting piece 51 enters the guide groove adjacent to the guide groove 24a corresponding to the position of the micro perforation 3b of the label continuous body 3 as shown in FIG. It may be. In such a case, the label continuous body 3 cannot be cut along the micro perforations 3b.

  Therefore, in this embodiment, the positioning member 17 shown in FIG. 12 is arranged behind the transfer endless belt 24 instead of the pressure receiving plate 16 shown in FIGS. FIG. 12 is a partial cross-sectional view showing the positional relationship between the transfer endless belt and the positioning member. FIG. 12A shows a state in which the cutting piece cuts the label continuous body, and FIG. This shows a state where the cut frame returns to the original position.

  The positioning member 17 is preferably provided on the platen frame 18 and is disposed to face the inner peripheral surface (lower side in the figure) of the transfer endless belt 24. The positioning member 17 includes a concavo-convex portion 17 a that engages with the inner teeth of the transfer endless belt 24, and the position of the guide groove 24 a of the transfer endless belt 24 when the cutting piece 51 cuts the label continuous body 3. The endless belt 24 for transfer is positioned so as to correspond to the position of the circumferential tip 51a of the cutting piece 51.

  When the cutting piece 51 cuts the continuous label 3, the transfer endless belt 24 is pressed toward the positioning member 17 by the cutting piece 51, as shown in FIG. The endless belt 24 for transfer is positioned by engaging the internal teeth with the concavo-convex portion 17a of the positioning member. Thereafter, when the cutting piece 51 returns to the original position, the transfer endless belt 24 is moved away from the positioning member 17 as shown in FIG.

  FIG. 13 is a partial cross-sectional view showing an operation for correcting the shift of the stop position of the transfer endless belt, FIG. 13 (A) shows a state before correction, and FIG. 13 (B) is corrected. Indicates the state. As shown in FIG. 13A, even if the stop position of the guide groove 24a of the transfer endless belt 24 is deviated to some extent from the position of the circumferential tip 51a of the cutting piece 51, the transfer endless belt 24 is not cut. Is pressed toward the positioning member 17 and the internal teeth of the transfer endless belt 24 engage with the concavo-convex portion 17a of the positioning member, so that the stop position of the transfer endless belt 24 is stopped as shown in FIG. Is corrected. As a result, the guide groove 24a of the transfer endless belt 24, the micro perforation 3b of the label continuous body 3, and the circumferential tip 51a of the cutting piece 51 are aligned in a straight line.

  FIG. 14 is a side view of the cutting piece and the interlocking mechanism in the released state of the operation lever, and FIG. 15 is a side view of the cutting piece and the interlocking mechanism in a state where the operation lever is gripped to start cutting the label continuous body. FIG. 16 is a side view of the main part for explaining the cutting operation of the cutting piece and the interlocking mechanism, and FIG. 17 is a side view of the main part for explaining the returning operation of the cutting piece and the interlocking mechanism.

  In the state where the operation lever 5 is released from the grip 10 shown in FIG. 1, the connecting plate 54 is connected to the vertical guide groove 58 of the vertical rail member 53 in the interlocking mechanism 52 shown in FIG. 14 by the force of the coil spring 12 pulling up the yoke portion 5 a. (FIG. 7) is positioned at the top. Accordingly, the Burster bracket 56 connected to the connecting plate 54 via the link bar 55 rotates slightly counterclockwise around the fulcrum pin 65, and the posture regulating pin 66 is moved to the guide window 69 of the lateral rail member 57. The cutting piece 51 is in contact with the upper inner wall surface 69 a and is slightly separated upward from the surface of the label continuum 3.

  When the operation 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 attitude 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. 15, 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. As a result, as shown in FIG. 16, the Burster bracket 56 moves toward the right end of the guide window 69 of the lateral rail member 57, and as shown in FIG. It moves along the 24 guide grooves 24a.

  The circumferential tip 51a of the cutting piece enters the guide groove 24a of the endless belt 24 for transfer 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 continuous body 3 is broken along the existing microperforations 3b. 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.

  The cutting piece 51 completes the cutting of the label continuous body 3 with the operating lever 5 fully gripped. Next, when the operation lever 5 is released, the link bar 55 is pulled up by the connecting plate 54 by the pulling force that the coil spring 12 (FIG. 1) acts on the connecting plate 54. Thereby, the cutting piece 51 starts to separate from the label continuous body 3.

  As shown in FIG. 17, the Burster bracket 56 rotates counterclockwise around the fulcrum pin 65, and the attitude regulating pin 66 contacts the upper inner wall surface 69a of the guide window 69, as shown in FIG. As described above, the cutting piece 51 is lifted 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 shown in FIG. 2, and the continuous label body 3 is transferred by a predetermined distance by the endless belt 24 for transfer. . 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, the cutting piece 51 is engaged with the guide groove 24a of the label continuous body 3 or the endless belt for transfer 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. Even if the label continuum 3 is transferred in the state where it is in a state, the taper shape of the circumferential tip 51a of the cutting piece and the taper shape of the guide groove 24a of the transfer endless belt are substantially the same inclined surface. The cutting piece 51 can be separated upward from the guide groove 24a of the endless belt for transfer without stopping the transfer of the label continuous body 3 (see FIG. 12).

  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.
