Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an electronic hand labeler capable of affixing an issued label to a partially issued object.

Technical Background and Problems In general, this type of hand labeler is designed to be held with one hand to affix the label, but the printer unit prints the necessary data while feeding the liner intermittently. be. In order to feed the liner, a label feed roller driven by a motor is used, but since hand labelers are portable, their weight must be reduced, and the motor must have a high output. I can't.

Therefore, the reliability of label feeding is low, and it is difficult to carry out constant continuous feeding 9, resulting in inaccurate printing.

OBJECTS OF THE INVENTION The object of the present invention is to provide an electronic hand labeler that can reliably feed labels and can perform continuous feeding.

SUMMARY OF THE INVENTION In the present invention, since a speed reduction mechanism is interposed between the bell feed shear roller and the motor, the motor only needs to have a low output.
The overall weight can be reduced, the label can be fed reliably, and since the bevel gear is biased in the axial direction, it is possible to mesh without backlash. This makes it possible to perform reliable continuous feeding.

Embodiment of the Invention An embodiment of the present invention will be explained based on the drawings. First, -・
The handheld printer section (1) and the stationary operation section (2) are airtightly connected by a cord (3). The operation section (
2) has a band (4) for use when moving, and the panel surface (5) includes a numeric keypad (6), function keys (7), changeover switches (8) (9), mode setting key Q0, and display section 0). etc. are provided.

Next, the hand printer section (1) has a handle α on its upper side, and a storage section α→ for holding and storing the paper αe wound into a roll on a support shaft αΦ is provided at the lower rear part. It is being A motor αQ consisting of a DC motor is installed in the center, and is meshed with this motor (driving gear α of 1Q is gear α8), and this gear 0 has two coaxially integrated small diameter gears α. This gear α group is spline-coupled to the support shaft so that it can move freely in the axial direction and is fixed in the rotational direction.
]) is meshed with the gear (a) which is biased in one direction. The rotary wheel fixed to the support shaft is meshed with a gear p6 fixed to a roller shaft (c) which is integrated with the label feed roller (c), thereby forming a speed reduction mechanism (i6-). The label feed roller (c) is equipped with a presser roller (
b) are joined. Incidentally, the drive gear αS and the gear 0 barrel α9) (C) (C) (C) are all formed of bevel gears.

Therefore, in the paper α, labels (c) are pasted at predetermined intervals on a long mount (c), and the label (g9) has a notch to form a label position detection portion. has been done. Then, the paper α → pulled out from the storage unit αυ is passed through the roller H and the printer unit (3■), and the label (C) is peeled off from the backing paper (C) at the label peeling unit 0 →.
The mount (c) is held between a label feed roller (c) and a presser roller (a) and is discharged. Further, the peeled label 29) passes between the pair of label guide rows 204 with its pasting surface facing down, and protrudes along the lower surface of the label pasting tool. This label applicator θ→ is rotatable around a support shaft Q and is biased by a threaded spring (371) so that its tip receives a downward biasing force.

Of course, a stopper is present to determine the rest position. Further, a label pasting detector 6→ is provided which optically interferes with the upper part of the label pasting tool OQ when the tip of the label pasting tool OQ is raised to the pasting position without interfering with the label pasting detector 6 in the stationary position.

Finally, two label detectors for detecting the label (c) are installed between the storage section α and the roller (3η).
Q are provided at predetermined intervals.

Note that αη is the object to be pasted.

In such a configuration, it is assumed that there are two types of label sheets, large ones and small ones. Now, let the small label be label A, and the large label be label B. Then, label A is detected by the label detector i4q and its operation is controlled, and label B is detected by the label detector i4q and its operation is controlled.

First, the operation of issuing a label (c) will be explained with reference to the flowchart of FIG. 7 and the timing charts of FIGS. 8 and 9. Depending on the set label (c), it is set whether it is label A or label B, and in the operation, a check is made to see whether it is label A or not. now,
If it is label A, it waits until a label pasting signal is output. This label pasting signal changes from the state shown in FIG. 4(α) to the pasting state shown in FIG. As shown in the figure, the output of the label pasting detector 0→ becomes L, so the timing of this fall is taken as the label pasting signal. As a result, the motor αQ is started, rotates the label feed roller (c), pulls in the mount (c), and issues a label in the label peeling section 0'3. Then, when the label detection section 0 detects the sill-appel position detection portion competition, the label position signal ■
comes out and stops motor 00.゛A label (c) is issued by repeating this operation.

At this time, a signal is also output from the label detector Qd), but this signal is all invalidated.

Also, when label (c) becomes label B, the 9th
According to the timing chart shown in the figure, the label position signal ■ becomes valid this time and the label is issued.

As shown in Figure 4, the label issued at the time of label affixing is pressed against the object (6) by the label affixing tool (3 valleys). There is no shortage of pressure contact force, and reliable pasting is achieved.

The next label is issued by the label pasting signal that is generated after pasting is completed as shown in Figure 4 (C1), so there is no timing overlap and no time loss. .

Since the driving force is transmitted from the motor αQ to the label feed roller (c) while being decelerated by the gear α9)C4 (c) using a bevel gear, a low-output motor α is sufficient. Since the gear 2 is axially biased by a compression spring eυ and meshed with one gear, backlash-free meshing between the two is possible, and the accuracy of the feed rate is high.Especially , constant velocity is obtained without any change in feed speed.In the above embodiment, only the gear (A) was energized, but in the meshing part using a bevel gear, all parts are relative to each other. It is desirable to be able to freely deviate in the axial direction.This allows for a state without backlash even if gears are used in the power transmission system, and ensures accurate feed speed. (c) Printing is performed accurately.

Effects of the Invention In the present invention, as described above, a deceleration mechanism using a plurality of gears is provided between the label feeding shear roller and the motor, so even if the motor has a small output, it is possible to reliably feed the label υ. As a result, the weight can be reduced, and since at least a part of the gears are biased in the axial direction as bevel gears when meshing, backlash-free meshing can be achieved. Thereby, constant speed feeding can be performed and printing accuracy can be improved.
