SUMMARY OF THE INVENTION A first object of the present invention is to provide an improved handle for an electrically selectable hand-held labeler in which the handle is powered.

A second object of the present invention is to provide an improved handle for a hand-held labeler that is constructed so that the electrical contact will not be temporarily broken if the labeler is subjected to an impact.

A third object of the invention is to provide a hand-held labeler in which the flexible electrical contacts are protected from damage.

A fourth object of the present invention is to provide a hand-held labeler having an improved connection between the labeler nosing 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. That's true. This device prevents flutter of the web against the feed wheel and eliminates the possibility of the feed dog slipping out of the five slits or holes.

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 housed inside the labeler's housing to protect it from damage from shock, 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 feed wheel for feeding the support web. We aim to create a compact hand-held labeler with the following features.

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 inside the feed wheel to avoid overhanging it. The deceleration 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 concession teeth disposed between the annular outer surfaces. There is also a further ball bearing for said further annular outer surface. To prevent rattles resulting from clearances between the outer surface of the feed wheel and the ball bearings, the ball bearings of each set are arranged to form a circle of smaller diameter than the respective annular outer surface. There is. 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;
The present invention relates to a hand-held labeler having an applicator for applying printed labels and a power source in the handle.

In order 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 occupancy 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 is designed so that the handle can be removed, and the electrical connection is automatically severed 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 moved 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. The roll and pasting position are installed in a new way. The keyboard and the second and third supports are attached to a rod that attaches the applicator roll of the applicator.

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 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 so that it is compact in both its closed and retracted positions. The label roll is mounted on a preferred rotatable mounting member and the force bar is rotated about the same axis as the mounting member.
It can be rotated freely. The force bar has an arcuate portion joined to a pair of spaced side walls. Preferably, the mounting members are pressed against each other by a pair of helical springs.

The present invention also relates to an improved device 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.
