Abstract

PURPOSE:To make it feasible to introduce sheets by providing a funnel-like sheet introduction device which becomes gradually open larger toward a sheet introduction side in one piece at the end of a sheet guide device. CONSTITUTION:When a labeled mount with a varying width is used, the handle part 4d of a label guide 4 is held and each label guide 4 is allowed to move so that a clearance between a label guide surface 4a and another label guide surface 4a almost coincides with the width of the labeled mount 2. Next, the labeled mount 2 is introduced into a label introduction guide part 4b of the label guide 4 in which the width of the labeled mount 2 is set. The label introduction guide part 4b is shaped like a funnel, gradually becoming open larger toward the introduction side of the labeled mount 2, and a label introduction orifice 4c is extensively formed in a direction almost crossing directly the width direction of the labeled mount 2 to meet the expanded opening width of the tip of the funnel.

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a paper guide device for a printer having a paper guide means for guiding paper inserted from a paper insertion slot to a predetermined printing position.

2. Description of the Related Art Conventionally, printers such as retail, industrial, or distribution barcode printers are provided with paper guides for guiding paper inserted from a paper insertion slot to a paper transport section.

In general, such paper guides have a paper guide surface formed along the transport direction of the paper in order to guide multiple types of paper such as labeled mounts with different width dimensions to a predetermined printing position. The guide surface is arranged to be movable in the width direction of the paper.

Problems to be Solved by the Invention Generally, the paper insertion slot formed on the side surface of the device for inserting paper into such a paper guide has a very narrow width in the thickness direction of the paper. Therefore, the work of inserting the paper becomes difficult, and at the same time requires a lot of effort and time.

Means for Solving the Problems The invention as set forth in claim 1 provides a paper guide device for a printer that includes a paper guide means inside the printer that guides paper inserted from a paper insertion slot to a predetermined printing position. A funnel-shaped paper insertion means that expands toward the paper insertion side is integrally provided at the end of the means.

Further, in the invention as claimed in claim 2, the paper insertion means is formed by expanding in the paper thickness direction and the paper width direction toward the paper insertion side, and the end portion on the paper insertion side is opened from the paper insertion slot. It was set up to protrude.

The invention according to claim 1 provides a funnel that expands toward the paper insertion side at the end of the paper guide means that is disposed inside the printer and guides the paper inserted from the paper insertion slot to a predetermined printing position. Since the paper insertion means of the shape is integrally provided, the paper insertion opening can be made wider in accordance with the width of the opening of the distal end of the paper insertion means.

Further, in the invention as claimed in claim 2, the paper insertion means is formed by expanding in the paper thickness direction and the paper width direction toward the paper insertion side, and the end portion on the paper insertion side is opened from the paper insertion slot. Since it is provided in a protruding manner, the degree of freedom in inserting the paper into the paper insertion means is greatly increased. In addition, even if the paper is placed at a predetermined distance in the thickness direction of the paper from the paper insertion slot, there is no need to newly install a dedicated label guide, etc., and only the paper insertion means can be used. This allows you to guide the paper.

Embodiment A first embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG. 1 shows the structure of a barcode printer. On the side surface 1a of the printer body 1, there is a roller 2a on which a roll-shaped labeled mount 2 as paper is attached.
A roller support arm 3 is provided to rotatably support the roller.

On the other hand, inside the printer main body 1 on the side la side,
A label guide surface 4 along the conveyance direction of the labeled mount 2
Two label guides 4 are provided as paper guide means, each having a shape a formed thereon.

However, the label guide surfaces 4a formed on each of these two label guides 4 are for guiding the inserted paper to a predetermined printing position.

In addition, at the ends of these label guides 4, as shown in FIG. 2, there is a label insertion guide part 4b as a funnel-shaped paper insertion means that expands toward the insertion side of the labeled mount 2.
is integrally provided, and a handle portion 4d is formed at the tip thereof to protrude from a label insertion opening 4C serving as a paper insertion opening formed on the side surface 1a of the printer main body l.

Further, as shown in FIGS. 3 and 4, this label guide 4 is disposed on a label guide support stand 4e so as to be movable in the width direction of the labeled mount 2.

As shown in FIGS. 5 and 6, on the opposite side of the label guide 4 sandwiching the label guide support stand 4e, there are two racks 5 facing each other and meshing with one pinion 5a.
b, and each rack 5b is connected to the label guide 4. This results in
As shown in FIG. 7, the label kite 4 moves symmetrically with respect to the center in the width direction of the label insertion opening 4C.

However, the rack 5b is guided and movably supported by two rack guides 5c (see FIG. 5).

Further, a daytent wheel 5d is mounted on the rotating shaft 5a of the binion 5a, and a daytent plate 5e formed of an elastic member or the like whose tip is in contact with the daytent wheel 5d is attached to the rack guide 5c by screws 5e. Fixed by As a result, the operation when moving the fourth label guide becomes stepwise.

In such a configuration, the labeled mount 2 guided into the apparatus by the label guide 4 is guided by the label guide 6 to the pressure contact area between the thermal head 7 and the platen 8, and after printing is performed, it is delivered to the label discharge port. Being expelled from 9 (
(See Figure 1).

When using labeled mounts 2 with different width dimensions, grasp the handle 4d of the label guide 4 and adjust the width of the labeled mount 2 by the distance between the label guide surface 4a and the other label guide surface 4a. Each label guide 4 is moved so as to approximately correspond to (see FIG. 3).

Furthermore, the labeled mount 2 is inserted into the label insertion guide portion 4b of the label guide 4, in which the width dimension of the labeled mount 2 has been set in this manner.

At this time, the label insertion guide part 4b is formed in a funnel shape that expands toward the insertion side of the labeled mount 2, and the label insertion opening 4c is opened to the labeled mount 2 in accordance with the expanded width at its tip. Since it is formed widely in a direction substantially orthogonal to the width direction of the label guide 4,
The degree of freedom in the insertion position is increased, and as a result, the operation of inserting the labeled mount 2 can be performed easily and quickly.

Furthermore, when the rolled labeled mount 2 is disposed adjacent to the label insertion slot 4c as in this embodiment,
The label insertion guide section 4b becomes very effective.

Next, a second embodiment of the present invention will be described based on FIGS. 8 and 9. As shown in FIG. 8, the paper guide device of this printer is provided with a label guide 10 as shown in FIG. 9 as paper guide means in place of the label guide 4 in FIG. 1. Therefore, the same reference numerals are used for the same parts as those described in the first embodiment, and the description thereof will be omitted.

However, this label guide 10 has a label guide surface 10a formed along the conveyance direction of the labeled mount 2, and at the end thereof, the labeled mount 2 is formed toward the insertion side of the labeled mount 2. Label insertion guide part 10 as a paper insertion means formed by expanding in the thickness direction and the width direction.
b is integrally provided, and the end of the label-attached mount 2 on the insertion side protrudes from the label insertion opening 4c.

In such a configuration, when the labeled mount 2 is inserted into the label insertion guide section 10b of the label guide 10, the tip of the label insertion guide section 10b expands in both the width direction and the thickness direction of the labeled mount 2. Since it is open, the degree of freedom in inserting the labeled mount 2 into the label guide 10 is greatly increased.

Also, make sure that the paper you are using is in the label insertion slot 4 of the printer body 1.
Regardless of whether the label is placed above or below c, the label insertion guide portion 10b alone can be used to insert the label without newly providing a dedicated label guide (not shown) or the like. As a result, the device can be simplified and the number of parts can be reduced.

In addition, in the above two embodiments, the labeled mount 2
Although the description has been made using a paper guide device equipped with a label guide 4 or a label guide 10 that is movable in the width direction,
This is not limited to, but includes paper guide means installed in printers that use only one type of paper, etc.
Although the paper width is fixed, a paper insertion means similar to that described above can be integrally provided at the end on the paper insertion side.

Effects of the Invention As described above, the invention according to claim 1 provides a paper guide device for a printer that includes a paper guide means inside the printer that guides a paper inserted from a paper insertion slot to a predetermined printing position. Since the funnel-shaped paper insertion means that expands toward the paper insertion side is integrally provided at the end of the means, the paper insertion opening can be widened to correspond to the width of the opening of the tip of the paper insertion means. I can do it. Therefore, the degree of freedom in the insertion position of the paper with respect to the paper guide means is increased, and as a result, it becomes possible to perform the paper insertion operation easily and quickly.

Further, as described above, the invention according to claim 2 is formed such that the paper insertion means is expanded toward the paper insertion side in the thickness direction and the width direction of the paper, and the end portion on the paper insertion side is expanded. Since it is provided so as to protrude from the paper insertion slot, the degree of freedom in inserting the paper into the paper insertion means is greatly increased. In addition, even if the paper is placed at a predetermined distance in the thickness direction of the paper from the paper insertion slot, there is no need to newly install a dedicated label guide, etc., and only the paper insertion means can be used. This allows you to guide the paper. Therefore, it is possible to simplify the device and reduce the number of parts.
