CONSTITUTION:Two label guides 4 as paper guide means having paper guide surfaces 4a formed thereto along the feed direction of label applied pasteboard are provided in a printer main body on the side of the side surface 1a thereof. The handle parts 4c protruding from the paper insertion port 4b formed to the side surface 1a of the printer main body are formed to the end parts of the label guides 4 and provided to label guide support stands 4d so as to be freely movable in the lateral direction of the label applied pasteboard.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a paper guide device for a printer that guides paper according to its width dimension.

2. Description of the Related Art Conventionally, in printers such as barcode printers for retail, industrial, or distribution use, multiple types of label mounts and the like having different width dimensions have been used.

In order to guide the paper to the proper printing position, such printers are provided with a paper guide that has a paper guide surface formed in the same direction as the paper transport direction and is movable in the width direction of the paper. . Then, by moving this paper guide in accordance with the width dimension of the paper, the paper is guided to the proper printing position.

Problems to be Solved by the Invention Since the paper guide of such a printer is provided inside the device, when setting the paper width dimension, it is necessary to open the top panel etc. provided in a part of the housing. It is necessary to move the paper guide by inserting one's hand into the apparatus through the opening, which makes it difficult to set the desired width dimension, and at the same time, it takes time.

Means for Solving the Problems In a printer that prints on multiple types of paper having different width dimensions, a paper guide surface is formed in the printer body along the conveyance direction of the paper, and is movable in the width direction of the paper. Two paper guide means are provided, and a handle portion protruding from a paper insertion opening formed on the side surface of the printer main body is integrally provided at the end of the paper guide means.

The handle provided on the paper guide means protrudes from the paper insertion slot formed on the side of the printer body, so when using paper with different widths, use the handle to move the paper guide. In other words, the width of the paper can be set from outside the apparatus. For this reason,
There is no need to perform complicated work such as putting your hand inside the device, and at the same time, the time required for doing so can be shortened.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 7. FIG. 1 shows the structure of a barcode printer, in which a roller support arm 3 rotatably supports a roller 2a to which a roll-shaped labeled mount 2 as paper is attached to a side surface 1a of the printer main body 1. is installed.

Moreover, inside the printer main body 1 on the side la side,
A paper guide surface 4a along the conveyance direction of the labeled mount 2
Two label guides 4 are provided as paper guide means in which a label is formed.

As shown in FIG. 2, the end of the label guide 4 is formed with a handle portion 4C that protrudes from the paper insertion slot 4b formed on the side surface 1a of the printer main body 1, and as shown in FIG. And as shown in FIG. 4, the labeled mount 2
The label guide support base 4d is provided movably in the width direction of the label guide support base 4d.

Furthermore, on the opposite side of the label guide 4 sandwiching the label guide support stand 4d, as shown in FIGS. 5 and 6, there are two racks 5b facing each other and meshing with one pinion 5a. are arranged, and this rack 5
b are connected to the label guide 4.

However, each of the racks 5b is guided and movably supported by two rack guides 5c, respectively.

Further, a daytent wheel 5d is mounted on the rotating shaft 5a of the binion 5a, and a detent 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 a screw 5e. Fixed by

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. Ejected from 9 (
(See Figure 1).

When using labeled mounts 2 with different width dimensions, grasp the handle 4c of the label guide 4 and adjust the width of the labeled mount 2 by grasping the distance between the paper guide surface 4a and the other paper guide surface 4a. Each label guide 4 is moved so as to substantially match the label guide 4.

Note that, as shown in FIG. 7, the label guide 4 moves symmetrically with respect to the center in the width direction of the paper insertion slot 4b.

In this way, since the handle portion 4c is provided to protrude from the paper insertion slot 4b, the width dimension of the label-attached mount 2 can be adjusted to the printer main body 1.
Settings can be made from outside the printer body 1, which eliminates the need for complicated operations such as putting your hand inside the printer body 1, and at the same time, it is possible to shorten the time required to do so.

Effects of the Invention As described above, the present invention provides a printer that prints on multiple types of paper having different width dimensions, in which a paper guide surface is formed in the printer main body along the conveyance direction of the paper. Two movable paper guide means are provided, and a handle protruding from the paper insertion slot formed on the side surface of the printer body is integrally provided at the end of the paper guide means, so that sheets of different width dimensions can be handled. When using the apparatus, the paper guide means can be moved using the handle, and the width of the paper can be set from outside the apparatus. Therefore, there is no need to perform complicated operations such as inserting hands into the inside of the device, and at the same time, the time required for this can be shortened.

The figure is an enlarged bottom view showing means for moving the label guide symmetrically, FIG. 6 is a plan view thereof, and FIG. 7 is a side view showing the direction of movement of the label guide.
