A fourth object of the invention is to provide a hand-held labeler having an improved connection between the labeler housing and the handle. .

A fifth object of the invention is to provide an improved apparatus for maintaining contact between the label support web and the feed teeth of a toothed feed wheel using circumferentially spaced rollers. It is to be. This device prevents flaking of the web against the feed wheel and eliminates the possibility of the feed dog becoming dislodged from the slit or hole in the web.

Other objects and features of the invention will be readily apparent to those skilled in the art.

SUMMARY OF THE INVENTION The present invention is directed to a compact hand-held labeler in which the main circuitry is confined to a small space.

The main circuitry is located within the labeler's housing to protect it from damage from impacts, such as when the labeler is dropped.

One or more circuit boards are compactly fitted between the housing and a subframe that mounts certain parts of the labeler. The circuit board is spaced apart from the housing. At least several circuit boards are secured to the subframe.

The present invention includes a housing with a handle, a label roll supported on the housing, a pressure sensitive label supported on a support web, a printhead, a label peeling device, a label applicator, and a supply for feeding the support web. The aim is to create a compact hand-held labeler with a feed wheel.

The feed wheel is driven by an electric motor, which for simplicity is preferably coaxial with the feed wheel. The electric motor is at least partially contained within the feed wheel to reduce bulk. A reduction gear driven by an electric motor is
It is likewise at least partially within the feed wheel, but preferably entirely within the feed wheel. The feed wheel is rotatably mounted and preferably rotates with minimal friction to save electrical energy. The feed wheel has an annular outer surface and a set of ball bearings abuts the outer surface and rotatably mounts the feed wheel. Preferably, three ball bearings contact the outer surface at equal intervals.

The feed wheel further has another annular outer surface spaced from said outer surface, with a feed dog disposed between the annular outer surfaces. There are another 61 ball bearings for said other annular outer surface. To prevent rattling resulting from clearance between the outer surface of the feed wheel and the ball bearing, each set of ball bearings is arranged to form a circle of smaller diameter than the respective annular outer surface. . The resilient mounting of the ball bearings ensures that all play between the ball bearings and the annular outer surface is eliminated, yet the feed wheel can rotate freely with minimal friction. .

The present invention includes: a housing, a handle coupled to the housing, a printhead having an electrically selectable printing element;
a stripping device for stripping the pressure-sensitive label from the support web;
Application for applying printed labels involves a hand-held labeler having a device and a power source in the handle.

To minimize the risk of damage to the labeler, the handle and housing are connected by a quick connection that allows separation of the handle and housing when excessive force is applied to the labeler. According to one particular embodiment, the quick connection includes a bendable member. An electrical connector is attached to the bendable member. The electrical connector forms an electrical circuit between the power source and the printhead when the handle is in place. However, the electrical connector pretends that the handle can be removed and automatically disconnects the electrical connection when the handle is removed.

In another feature of the invention, the printhead includes a plurality of thermal printing elements that cooperate with a small diameter platen roll to print selected characters on the label. The column of printing elements is
With the device according to the invention it is possible to precisely align the axis of the platen roll. According to a particular embodiment, the printhead is mounted on an oversized track.

An adjustment mechanism can be used to make adjustments to match the print head to the platen roll. One particular embodiment has a pair of bearings within the support, each bearing having an adjustment screw threaded thereon that can be turned to precisely align the print head with the platen roll. The pressure exerted by the platen roll on the label support web can be adjusted as well to optimize printing. Another feature of the invention is that the platen roll can be pulled away from the printhead to provide access for cleaning the printhead. The platen roll can be moved between a closed position and an open position, and can also be selectively held in an intermediate partially open position. In another feature of the invention, the printhead is attached to a first support, a second support below the first support attaches the first support, and a third support is attached to the platen. Roll and paste attaches the position in a novel way. The keyboard and the second and third supports are attached to a rod that attaches the mounting roll of the mounting device.

A feature of the invention is that the printed circuit board is cushioned, i.e., resiliently mounted, to minimize damage in the event of a shock to the labeler, such as when the labeler is dropped. An improved compact construction of a hand-held labeler is obtained. It is also a feature of the present invention that a holder is provided that has a means for holding printed circuit boards spaced and facing each other while minimizing impact damage. Preferably, the holder is constructed of a flexible rubber material that flexes resiliently upon impact to facilitate assembly of the printed circuit board. In one embodiment of the invention, several printed circuit boards are secured at spaced intervals to parts of the labeler with rubber members.

Another feature of the handheld labeler is an improved force bar or force bar member on the label supply roll. The force bar rotates over the holder and is therefore compact in both its closed and retracted positions. The label roll is preferably rotatably attached to the member, and the force bar allows the attachment to rotate about the same axis as the member. The force bar has an arcuate portion joined to a pair of spaced side walls.

For attachment, the members are preferably pressed against each other by a pair of helical springs.

The present invention also relates to an improved apparatus for attaching a feed wheel to a labeler. According to the invention, the feed wheel is mounted from the outside with a plurality of rolling contact members in contact with at least one annular portion of the feed wheel, which resist the forces exerted by the feed wheel when feeding the support web. Two opposing rolling contact members are rigidly mounted. Therefore, the axis of the feed wheel does not move when feeding the web, since the two rolling contact members provide reference points.

Preferably, the third rolling contact member resiliently presses the annular member along the direction of the force exerted by the feed wheel during feeding.

For installation, member 71 is inserted into hole 69 and its flange 74 is held against the outside of subframe portion 56 by screws 75. The outside of tubular portion 72 fits snugly into hole 69. Preferably, the electric motor 76 is completely inside the tubular section 72 and the reduction gear 77 is also completely inside the tubular section 72.

The shaft encoder foot protrudes slightly beyond the electric motor 76. A screw 78 is screwed into the end of the speed reducer 77 through a hole 79. As shown in FIG. 11, there is a gap between the mounting member 71 and the inside of the feeding wheel 29. As shown in FIG.

Feed wheel 29 has a pair of annular outer surfaces 80.81. On the outer periphery of the feed wheel 29 between its outer surfaces 80.81 a plurality of teeth 92.93 are arranged in a predetermined pattern.

has a pin 86 for mounting a rolling contact member, in particular a ball bearing 87. As shown in FIG. 11, the outer ring of ball bearing 87 contacts outer surface 80 at three contact points. Each holder 83, in its as-molded condition, is shaped such that the circle formed by the ball bearings 87 at the point of contact is smaller than the diameter of the respective outer surface 80 or 81. Each holder 83 can be expanded slightly. Connecting portion 85 assists in this expansion. When assembling the holder 83 and its ball bearing 87 to the feed wheel 29, the holder 83 is slightly expanded and moved into position around the outer surface 80 or 81. ball bearing 87
Since there is no clearance between the outer ring and the outer surface 80 or 1181, the holder 83 removes any looseness. As shown, each set of ball bearings 87 supports the feeding holder 29 at three locations, specifically at angular intervals of 120°.

The feed wheel 29 is mounted to rotate with very little friction. Reversal of the feed wheel 29 can be prevented either by the electric motor 76 itself or by a suitable known type of anti-backup device.

It has a hanging portion 323 which is attached to 2. Each hanging part 3
23 is electrically connected to a ribbon connector 313.

The top portion 324 of the coupling member 315 is provided with a plurality of slots 325 that are aligned perpendicularly to the contacts 312, each slot being wide enough to receive a rigid contact 326. The coupling member 315 has outwardly extending protrusions 327 , 328 spaced apart above the flanges 329 , 330 of the coupling member 318 . Handle 3
01 is a pair of cooperating protrusions 327, 328 and flange 3
29.330 is used to attach or connect the handle 301 to the handle 300 by sliding it over the housing 300 from the rear. The handle 301 is held in the position shown in FIG. 24 by a latch 331 consisting of a finger operated latch member 332 and a spring 333 contained in a mirrored pocket 334, 335 in the handle portions 306, 307. Latch member 332 latches housing 300. When the handle 301 is moved from the removed, uncoupled position to the attached position, the contact 326 enters the slot 325 and deflects the spring finger 321 from the imaginary position shown at PL to the solid position. When the handle is still slightly outside the installed position (housing 3
00), contact point 312
hits stop 337. Once in this condition, the spring fingers 321 of the contacts 312 cannot move in either direction when the labeler 299 is subjected to an impact, such as when dropped, for example. Contact 326 holds contact 312 against stop 337.

Stop 337 prevents contact 312 from separating from contact 326 and losing electrical contact. With this method, when the labeler 299 receives a shock, the electrical connection between the battery 309 and the storage device 340 is broken, and the
It is impossible for circuit 338 (FIG. 19) to lose memory. Upper portion 324 allows contacts 326 to make electrical contact with contacts 312, but acts as a protector to prevent damage to contacts 312, such as when removing handle 301 for recharging. Since the connecting member 315 is a single molded rubber structure, manufacturing cost is low. Protrusion 3

1 is shaped so that it can be separated from, or come off from, the housing 300. To help with this, even if the latch 331 is engaged, the flanges 327, 328
can be elastically deflected and passed through the flanges 329 and 330.

Connecting member 315 is not directly connected to two mirror image housing portions (as shown in FIGS. 2, 12, 13, and 14), but rather is connected to housing portions 304, 305.
It is connected to a connecting member 318 fixedly attached therebetween. In this way, the coupling action does not occur where the housing 300 is divided. As shown, the connecting member 318 has a screw 341 passed through the hole 342 and an annular member 343 that is an integral part of a single-piece plastic connecting member.
It is fixed by screwing into the Another screw (not shown) is screwed into the annular member 343 through the hole 342'. As a result, housing portions 304, 305 are securely coupled to coupling member 31g. .

Referring to Figure 1, subframe 303 is illustrated having substantially mirror image subframe portions 344,345. Subframe portion 344 has an axially aligned hole 346 in a tubular member 347 integrally molded into subframe portion 345 . The end wall of the tubular member 347 (first

Positioning the feed wheel 357 relative to the ball bearing 366 such that the annular portion 362, 363 contacts and is supported by the ball bearing 366 causes the soft resilient 373, 374 to flex outwardly. This method ensures that all play between the ball bearing 366 and the outer circumferential surface of the annular portion 362,363 is removed. The ball bearings 366 attached to the section 369 are arranged at equal angles A to the centerline CL. Centerline CL lies along the line of force exerted by web W on feed wheel 357 as feed wheel 357 advances web W; The direction of this force is in the direction indicated by arrow F.
