Description

    The present invention relates to a printer, and more particularly to a printer provided mainly in a portable label printing and pasting machine.

    2. Description of the Related Art Conventionally, it is necessary to perform a print arrangement operation for selecting a necessary print character in a printer provided in a portable label printing and pasting machine or other printing device. This will be described with reference to FIGS.

    FIG. 5 is a side view of a conventionally known portable label printing and pasting machine 1, which includes a handle 3 formed on a pair of side plates 2 on the left and right (front and back in FIG. 5), The operating lever 4 that is pivotally attached to the side plate 2 is gripped and released, so that printing is performed on the label piece 8 of the label continuous body 7 by the printer 5 and the ink roller 6, and printing is performed from the mount of the label continuous body 7. The used label piece 8 is peeled off, and can be attached to a predetermined article (for example, a product) by the attaching roller 9.

6 is a sectional view of the printer 5 and FIG. 7 is a sectional view taken along line VII-VII in FIG.
The printer 5 includes a pair of left and right printer frames 10, a selection wheel 11 of a plurality, that is, multiple rows (three rows in the illustrated example), an operation member 12, and a multiple row (in the illustrated example, the selection wheel 11). And the same endless band 13 for printing).

    FIG. 8 is an exploded perspective view of the selection wheel 11 and the operation member 12, and the wheel support bracket 14 provided in the printer frame 10 is spanned between the pair of left and right support plates 15 and the support plate 15. The wheel space 17 is formed between the pair of left and right support plates 15 and the arc-shaped plate 16.

The selection wheel 11 is coaxially overlapped next to each other in the wheel space 17 so as to be rotatable around the axial direction.
The selection wheel 11 has a plurality of (seven in the illustrated example) inner peripheral engagement grooves 18 formed at equal angular intervals on the inner peripheral surface thereof, and the outer peripheral surface thereof also at equal angular intervals. A plurality (seven in the illustrated example) of outer peripheral engagement grooves 19 are formed.

The operation member 12 selects any one of the selection wheels 11 in the axial direction of the selection wheel 11, and can rotate any of the selected selection wheels 11 around the selected axis.
That is, the operation member 12 can be moved and operated along the axial direction of the selection wheel 11, and the operation knob 20 that can be rotated around the axial direction, and can be reciprocated and rotated in the selection wheel 11. And a knob shaft 21 that can be operated by the operation knob 20.
The knob shaft 21 is provided with a drive pin 22 that engages with the inner peripheral engagement groove 18 of the selection wheel 11 selected in the row direction so that the selection wheel 11 can be rotationally driven.

    An indicator 23 is provided between the operation member 12 and the wheel support bracket 14. Each of the support hole 25 formed in the support plate 24 of the indicator 23 and the pair of left and right support plates 15 of the wheel support bracket 14 is provided. The knob shaft 21 of the operation member 12 is inserted into the guide hole 26 so as to be reciprocally movable and rotatable.

    In particular, as indicated by phantom lines in FIG. 7, the print endless band 13 has a plurality of print characters 27 and heading characters 28 formed around it, and inner peripheral projections 29 formed at a predetermined pitch are selected. The wheel 11 can be engaged with the outer peripheral engagement groove 19.

Returning to FIG. 8, the indicator 23 integrally forms a heading frame 30 on the support plate 24, and selects one of the print rows depending on the position of the pointer 31.
The knob shaft 21 is formed with a plurality of (four in the illustrated example) circumferential grooves 32 at a predetermined pitch in the axial direction, and the engagement / disengagement member provided in the printer frame 10. (For example, the steel ball 33 and the spring 34) can be engaged with and disengaged from the circumferential groove 32, so that the heading characters 28 of the printing endless band 13 in the column direction can be selected with a predetermined sense of moderation.

In particular, as shown in FIG. 7, the printing endless band 13 is applied with a predetermined tension between the selection wheel 11 and the moderation piece 36 provided in the ink roller facing opening 35 of the printer frame 10. It is turning.
The moderation piece 36 is rotatable around a piece shaft 37 and is provided with a moderation spring 39 that urges the moderation piece 36 via a pressing plate 38.

In the printer 5 having such a configuration, the operation knob 20 of the operation member 12 is taken in and out in the axial direction of the knob shaft 21, and an arbitrary print row (print endless band 13) is selected from the multi-row print endless band 13. Then, the drive pin 22 rotates and drives the predetermined (one) selection wheel 11 corresponding to the selected print endless band 13, so that the print character 27 is moved to the ink roller while viewing the heading character 28. It is located in the opposed opening 35.
In particular, as shown in FIG. 6, a through hole 10 </ b> A is formed in the printer frame 10 (in the illustrated example, on the right side in the drawing). With the shaft end 21A of the shaft 21 engaged with the through hole 10, the print selection operation is completed.

However, in order to ensure the operability of the operation knob 20 in the operation member 12, even if the operation member 12 is pushed in to the innermost part, as shown by the phantom line in FIG. It protrudes outward from the left or right side plate 2 of the applicator 1. Further, the operation knob 20 of the operation member 12 is not accommodated in the printer frame 10 because the indicator 23 exists between the operation knob 12 and the printer frame 10.
Therefore, when the label piece 8 is affixed to a product or other article using the portable label printing and pasting machine 1, the operation knob 20 of the operation member 12 is not carelessly used for the product, the surrounding article, the human body, or the like. When an external force greater than the setting is applied to the knob shaft 21 by pushing, the drive pin 22 of the knob shaft 21 remains engaged with the inner peripheral engagement groove 18 of the selected wheel 11 in the wheel space 17, so that printing is performed. There is a problem that the arrangement of the endless band 13 is changed from the set state and affects the printing accuracy and printing quality.
Moreover, if the printing and pasting operation is continued without noticing the change in the arrangement, there is a problem that information on the label piece 8 is erroneously displayed.

    Note that the above-described problem is not limited to the portable label printing and pasting machine 1, and even in a desktop type printing apparatus, the operator carelessly operates the operation member or the operation knob of the printer after the print array setting is completed. It is a problem that occurs in the same way when touched.

It is the II-II sectional view taken on the line of FIG. 3 is an exploded perspective view of the selection wheel 11 and the operation member 41. FIG. It is explanatory drawing seen from the axial direction of the knob shaft 21 of the control member 43 in the operation member 41 part. It is a side view of the conventionally well-known portable label printing sticking machine. 2 is a cross-sectional view of the printer 5. FIG. FIG. 7 is a sectional view taken along line VII-VII in FIG. 6. FIG. 3 is an exploded perspective view of a selection wheel 11 and an operation member 12 portion.

    In the present invention, since the neutral space that guarantees the free rotation of the knob shaft is formed in the printer frame, the print arrangement once selected and set may be shifted even if an external force is applied to rotate the operation member. A printer that does not exist is realized.

Next, a printer 40 according to an embodiment of the present invention will be described with reference to FIGS. However, the same parts as those in FIGS. 5 to 8 are denoted by the same reference numerals, and detailed description thereof will be omitted.
1 is a sectional view of the printer 40, and FIG. 2 is a sectional view taken along the line II-II of FIG.
Like the printer 5 (FIG. 5) described above, the printer 40 includes a pair of left and right printer frames 10, the selection wheels 11 in a plurality of, that is, multiple rows (three rows in the illustrated example), and the operation. The operation member 41 corresponding to the member 12 and the print endless band 13 in multiple rows (in the example shown, the same three rows as the selection wheel 11) are provided.

    FIG. 3 is an exploded perspective view of the selection wheel 11 and the operation member 41. Like the printer 5 (FIG. 8) described above, the wheel support bracket 14 provided in the printer frame 10 is a pair of left and right wheels. A wheel space that includes a support plate 15 and an arcuate plate 16 spanned between the support plates 15 and that rotatably accommodates the selection wheel 11 between the pair of left and right support plates 15 and the arcuate plate 16. 17 is formed.

    In particular, as shown in FIGS. 1 and 3, the printer 40 according to this embodiment is different from the printer 5 in that the printer frame 10 has a shaft end located on the opposite side of the operation knob 20 of the knob shaft 21. The neutral space 42 that accommodates the portion 21 </ b> A and the drive pin 22 to ensure the free rotation of the knob shaft 21 is formed, and the operation member 41 can regulate the free rotation angle of the operation member 41 in the neutral space 42. This is the point that a restricting member 43 is provided.

    In particular, as shown in FIG. 1, the neutral space 42 is separated from the wheel space 17 that accommodates the selection wheel 11, more specifically, adjacent to the wheel space 17, at the innermost portion of the printer frame 10. Is provided.

In particular, as shown in FIG. 3, the restricting member 43 includes a positioning engagement / disengagement groove 44 formed at a predetermined angular pitch in the circumferential direction of the attachment portion of the knob shaft 21 to the operation knob 20. And a pair of left and right engaging / disengaging protrusions 45 that engage and disengage with the engaging / disengaging groove 44.
The positioning engagement / disengagement grooves 44 are formed in the operation knob 20 by aligning the position and number (seven in the illustrated example) with the inner peripheral engagement grooves 18 of the selection wheel 11 in the axial direction of the selection wheel 11. ing.
The pair of left and right engaging / disengaging protrusions 45 are arranged so as to straddle the support hole 25 of the support plate 24 on the operation knob 20 side of the indicator 23 attached to the knob shaft 21 so as to be integrally operable in the axial direction of the knob shaft 21. Provided.

FIG. 4 is an explanatory diagram viewed from the axial direction of the knob shaft 21 of the restricting member 43 in the operation member 41, and the pair of left and right engagement / disengagement protrusions 45 enter the inner part of the operation knob 20 and engage / disengage for alignment. The pair of grooves 44 can be engaged and disengaged.
The engagement / disengagement force between the alignment engagement / disengagement groove 44 formed in the operation knob 20 and the engagement / disengagement protrusion 45 engaged / disengaged from the alignment engagement / disengagement groove 44 is defined as a knob shaft regulating force.

As shown in FIG. 2, the printing endless band 13 is wound around the selection wheel 11 and the moderation piece 36 and is provided with a moderation spring 39 for urging the moderation piece 36. The relative ratio between the moderate biasing force of the moderate spring 39 and the knob shaft regulating force by the regulating member 43 can be adjusted.
That is, the magnitude of the moderation biasing force of the moderation spring 39 that is relatively distant from the operation knob 20 and the magnitude of the knob shaft regulating force between the positioning engagement / disengagement groove 44 and the engagement / disengagement protrusion 45 that are relatively close to each other. By arbitrarily setting, the click feeling when the operation dial 20 is rotated can be arbitrarily adjusted and set.
In order to set the magnitude of the shaft regulating force, for example, the size and length of the engagement / disengagement projection 45 or the material can be arbitrarily selected.

In the printer 40 having such a configuration, after the normal print selection operation is performed by operating the operation member 41 in the axial direction and the rotation direction, the operation knob 20 of the operation member 41 is pushed into the innermost portion of the printer frame 10. Then, the shaft end 21A of the knob shaft 21 and the drive pin 22 are moved into the neutral space 42, and the knob shaft 21 is set at the neutral position. More specifically, the shaft end 21A of the knob shaft 21 is located between the support plate 15 located on the right side of the wheel support bracket 14 in FIG. 1 and the inner wall surface 10B of the printer frame 10, and the drive pin Reference numeral 22 denotes a guide hole 26 of the wheel support bracket 14.
Even if some external force is applied to the operation knob 20 at this neutral position, the operation knob 20 and the knob shaft 21 only idle in the neutral space 42, and the rotational force of the knob shaft 21 is selected via the drive pin 22. 11 and the endless band 13 for printing, and the set printing arrangement is not affected.

However, since the pair of left and right engagement / disengagement protrusions 45 are engaged with the regulating member 43, that is, the alignment engagement / disengagement groove 44 formed at the root portion, at the root portion of the operation knob 20, the knob shaft 21 is disordered. Instead of rotating freely, it rotates only to the angular position regulated according to the angular pitch of the positioning engagement / disengagement grooves 44.
Therefore, even when the external force acts on the operation knob 20 and the knob shaft 21 is freely rotated or idled, the drive pin 22 of the knob shaft 21 is not engaged with the positioning engagement / disengagement groove 44, that is, the inner periphery of the selection wheel 11. The angular position that matches any position of the engagement groove 18 is maintained (see the phantom line in FIG. 2), and the drive pin 22 always maintains the posture facing the inner peripheral engagement groove 18 of the selection wheel 11. Therefore, even if the operation knob 20 is operated to be pulled out from the printer frame 10 along the axial direction of the knob shaft 21 in order to set the print arrangement of the printer 40 to a new one, The drive pin 22 can always be smoothly engaged with the inner peripheral engagement groove 18 of the selection wheel 11 in the wheel space 17 and a normal print selection operation can be performed without any trouble.

    Furthermore, the regulating member 43 is provided in the vicinity of the operation knob 20 of the operation member 41, so that it is easy to feel the click feeling at hand and the operability can be improved. Of course, as described above, an arbitrary click feeling can be set by adjusting the relative ratio between the knob shaft regulating force by the regulating member 43 and the moderation biasing force of the moderation spring 39.

    Thus, when the heading character 28 (printing character 27) of the printing endless band 13 is selected and set, and the operation dial 20 is pushed into the inner part of the printer frame 10, the knob shaft 21 and the drive shaft 21 are driven to the neutral position in the neutral space 42. Since the pin 22 is positioned, there is no possibility that the printing endless band 13 once set will be inadvertently displaced, and the printing accuracy and printing quality on the label piece 8 can be maintained at a predetermined level.
