The labeler in accordance with the present invention is constructed so that a plurality of labels which are consecutively stuck onto a carrier strip are separated in sequence from the carrier strip by turning back the carrier strip at the carrier strip turnback part and intermittently feeding said carrier strip along with the rotational movement of the feed drum. Two feed rollers which depress the carrier strip onto the feed drum are provided. A circular guide member which forms a clearance for feeding the carrier strip between said guide member and the outer periphery of the feed drum is provided between said two fed rollers, and a pivotable frame is provided between the feed rollers for which said guide member is not provided, and a stripper is provided on the inside of the pivotable frame to separate the carrier strip fed by the feed drum from said feed drum. The pivotable frame is provided with a cutter edge for cutting the carrier strip so that the carrier strip separated at the carrier strip turnback part can be cut.

BACKGROUND OF THE INVENTION 
The present invention relates to a manually-operated labeler which is 
adapted to separate and forward labels in sequence from the carrier strip 
by turning back the carrier strip onto which a plurality of labels are 
stuck consecutively at a carrier strip turnback part while intermittently 
feeding the carrier strip. 
This type of labeler is provided with a feed drum which engages with the 
carrier strip to feed the carrier strip, and said labeler is provided with 
a circular guide member which positioned to form a carrier strip feeding 
clearance between said guide member and the outer periphery of the feed 
drum, and a feed-in roller for feeding the carrier strip into said carrier 
strip feeding clearance is positioned at one end of said guide member and 
a feed-out roller for feeding the carrier strip out of the carrier strip 
feeding clearance is positioned at the other end of said guide member. 
In such carrier strip feeding device, there is a possibility that the 
carrier strip will be fed back into the carrier strip feeding clearance by 
the feed-in roller if the carrier strip fed from the feed-out roller is 
not separated from the feed drum. 
Moreover, this type of labeler is disadvantageous in that external small 
material such as, for example, dust are carried by the feed-in roller into 
the carrier strip feeding clearance if two feed rollers are opposed to the 
feed drum, and that the outer periphery of the feed drum is covered and 
the cleaning of the feed drum is obstructed by the cutter for cutting the 
carrier strip fed from the feed-out roller since said cutter should be 
provided near the feed-out roller. 
An object of the present invention is to provide a labeler in which the 
carrier strip fed from the feed-out roller to the outside is positively 
separated from the feed drum. 
Another object of the present invention is to provide a labeler in which a 
label stuck on the carrier strip can be easily separated from the carrier 
strip by a projection which is provided on the external surface of said 
covering member when the label comes in contact with the covering member.

SUMMARY OF THE INVENTION 
The present invention provides a manually-operated labeler which 
intermittently feeds the carrier strip onto which a plurality of labels 
are consecutively stuck, turns back the carrier strip at a carrier strip 
turnback part and separates and forwards the labels from the carrier strip 
at the carrier strip turnback part, wherein the feed drum which engages 
with the carrier strip and is driven by a movement of the lever is 
employed for feeding said carrier strip. A circular guide member opposed 
to the outer periphery of said feed drum in the main casing is provided to 
form a carrier strip feeding clearance, a feed-in roller which depresses 
the carrier strip onto the feed drum and feeds the carrier strip into the 
carrier strip feeding clearance in cooperation with the feed drum and a 
feed-out roller which depresses said carrier strip onto the feed drum and 
feeds out said carrier strip from the carrier strip feeding clearance in 
cooperation with said feed drum are each provided along the outside of 
said feed drum which is not opposed to said circular guide member, and a 
covering mechanism which covers the outside of said feed drum is provided 
between said feed-in roller and the feed-out roller, said covering 
mechanism comprising an openable covering member provided between the 
feed-in roller and the feed-out roller and a locking means, which 
maintains said covering member closed when the covering member is closed, 
such as, for example a resilient engaging piece or a frictional surface 
provided on said covering member. Said covering member is provided with a 
pivotable frame which has pivot points at the side toward said feed-out 
roller and the side toward said feed-in roller as an end of pivotal motion 
and at least one stripper which is provided to positively separate the 
carrier strip, which is engaged with said feed drum and fed by the 
feed-out roller, from the feed drum inside said pivotable frame, said 
stripper being made of, for example, a projecting member the tip of which 
is inserted into a peripheral groove which is provided in the 
circumferential direction on the outer periphery of the feed drum. 
Said pivotable frame is provided with a cutting edge such as, for example, 
a sawtoothed edge for cutting the carrier strip, the cutting edge being 
provided at the side toward the feed-out roller, whereby said carrier 
strip is cut as required. 
At least one thin ridge extends from said feed-in roller side toward said 
feed-out roller side on the external surface of said pivotable frame to 
facilitate removal of a label which is erroneously stuck to the external 
surface of the pivotable frame. 
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
Refering to FIG. 1, the main casing 10 has a handle 11 and a holder 12 for 
the carrier strip 20 onto which a plurality of labels 21 are stuck. 
The lever 30 which is always urged by the resetting spring 31 in the 
direction in which said lever 30 moves away from the handle 11 is pivoted 
on said main casing 10. The extension of said lever 30 in the main casing 
10 is formed as an actuating part 32 which is provided with the driving 
means for the printing device 40 and the feeding device 50. Said printing 
device 40 is vertically moved in the figure as the actuating part 32 of 
the lever 30 is turned and is accordingly pressed on or moved away from 
the label receiving segment 60. The printing device 40 described thus far 
is a conventionally known printing device 40. 
Said printing device 40 is provided with the ink roller 41 which is adapted 
to contact or approach the lower surface of the printing device 40 when 
said printing device 40 is at the uppermost position and moves away from 
the lower surface of the printing device 40 due to the impression force of 
the printing device 40 when said printing device 40 is at the lowermost 
position. This ink roller 41 is also constructed as in the conventional 
labelers. 
Said feeding device 50 is provided with driving means such as, for example, 
a rack gear 51, one-way clutch 52 which engages with said rack gear 51 and 
feed drum 53 which is coupled to said one-way clutch 52. 
Said feed drum 53 has the feed rollers 54 and 55 positioned adjacent 
thereto which depress the carrier strip onto the feed drum at the carrier 
strip feed-in side and the carrier strip feed-out side, respectively, and 
a circular guide member 57 is provided along and spaced from the 
circumference of the feed drum 53 between said feed rollers 54 and 55. 
Said feed-in roller 54 and feed-out roller 55 are mounted on said main 
casing 10 so that these rollers are located outside said feed drum 53, and 
said circular guide member 57 is housed in the main casing and opposed to 
the outer periphery of said feed drum 53 in the main casing. 
Said feed rollers 54 and 55 and said guide member 57 are fabricated as a 
single assembly as shown in FIG. 2, and the feed rollers 54 and 55 are 
provided with gears 541 and 551 which engage with the gear 533 provided on 
the other periphery of the feed drum 53. 
Said feed drum 53 is provided with engaging projections 531 at specified 
distances on the outer periphery so that the carrier strip 20 engages with 
said engaging projections 531. 
Said carrier strip 20 is provided with a number of engaging holes in 
sequence so that the carrier strip 20 is fed from the feed-in side to the 
feed-out side while said engaging projections 531 of the feed drum 53 are 
engaged in said engaging holes. 
Said label receiving segment 60 is pivoted on the main casing 10 coaxially 
with the feed-in roller 54 of the said feeding device 50 as shown in FIG. 
1, and a turnback edge 61 which turns back the carrier strip 20 is formed 
at the free end thereof and the surface near the turnback edge 1 is a 
resilient receiving surface 62, the printing device 40 being applied to 
the label 21 stuck on the carrier strip 20 as it overlies said resilient 
receiving surface 62 to place the printing onto the label 21. 
A depression member such as, for example, depression roller 70 is provided 
ahead of said label receiving segment 60 and the printed label 21 is 
depressed and stuck onto an article by said depression roller 70. 
The covering mechanism 80 is positioned at the feed-out side of said 
feeding device 50 and is provided with a covering member 81 and a locking 
means which locks said covering member. 
Said covering member 81 has a pivotable frame 813 which has the pivot 
shafts 811 and 811' engaged with casing 10 below said feed-out roller 55 
and a free end 812 which extends to a position near the feed-in roller 54, 
a cutter, for example the sawtoothed edge 814, which is provided at the 
pivoted end parallel with said feed-out roller 55 of said pivotable frame 
813 and stripper 815 which is provided on the internal surface of said 
pivotable frame 813 so that said stripper extends into at least one 
circumferential groove provided on the outer periphery of said feed drum 
53. Said covering member 81 is constructed so that it can be pivoted 
around said pivot shafts 811 and 811' as required as shown in FIG. 3 and 
can be opened to observe the body of the feed drum 53 from the bottom of 
the main casing 10. 
A locking means is provided to lock said covering member 81 when the 
covering member is closed as shown in FIG. 4 and, in the embodiment, said 
locking means is a resilient engaging member 82 which engages with the 
covering member 81. 
The labeler of the present invention is as described above. If the lever 30 
is operated several times after the label receiving segment 60 is turned 
as shown with a 2-dot broken line in FIG. 1, the carrier strip 20 is 
inserted between the feed-in roller 54 and the feed drum 53 and the label 
receiving segment 60 is returned to the position shown by the solid line. 
The feed drum 53 is rotated by the returning motion of the lever 30, the 
carrier strip 20 is automatically fed into the carrier strip feeding 
clearance 56 by the feed drum 53 and the feed-in roller 54 and 
automatically fed out from the carrier strip feeding clearance 56 by the 
feed-out roller 55, so that the carrier strip 20 is automatically set by 
the feed drum 53 and a pair of feed rollers 54 and 55. 
The carrier strip 20 engaged by said feed drum 53 is separated from the 
feed drum 53 by the stripper 815 which is inserted into the 
circumferential groove 532 and fed out of the main casing 10 while being 
guided by the internal surface of the pivotable frame 813. The carrier 
strip 20 fed out of the maain casing 10 can be cut as required by the 
sawtoothed edge 814. 
In case of this labeler, the outer periphery of the feed drum 53 can be 
partly exposed by turning said covering member 81 as shown in FIG. 3 and 
therefore the outer periphery can be cleaned and, if the covering member 
81 is closed as shown in FIG. 4, the feed drum 53 can be protected from 
deposit of foreign matter. 
In the embodiment, since the pivotable frame 813 of said covering member 81 
is provided with the stripper 815 and the cutter 814, the stripper 815 and 
the cutter 814 can be set at the specified positions or removed from the 
specified positions simply by pivoting the pivotable frame 813. 
The pivotable frame 813 of said covering member 81 is preferably provided 
with at least one ridge 816 extending from the feed-in roller 54 toward 
the feed-out roller 55 as shown in FIG. 5. The carrier strip 20 has a 
number of labels on its whole length when the carrier strip 20 is set on 
the labeler. When the carrier strip 20 is set on the feed drum 53, the 
labels on the carrier strip 20 ahead of the carrier strip turnback part 61 
should be removed by hand. Actually, in many cases, a label which is 
inadvertently left on the carrier strip 20 is separated at the feed-in 
roller 54 and pushed up and stuck onto the external surface of the 
pivotable frame 813. If the ridge 816 as described above is provided on 
the pivotable frame 813, the label stuck on the pivotable frame 813 can be 
easily removed. 
Said pivotable frame 813 is preferably provided with a window 817 and a 
cutaway part 818 through which the engaging projection 531 of the feed 
drum 53 can pass.
