Abstract

PURPOSE:To improve the productivity and maintainability of a device by providing a guide unit as a paper guide and mounting it detachably on a feed opening of a housing main body. CONSTITUTION:In a label printer 1, a guide base 5 of a guide unit 8 is inserted into a rectangular opening so as to fix a guide plate 4 to a housing main body 18, so that sheet guides 2 and 3 are positioned in the housing main body 18. Accordingly, in this label printer 1, the sheet guides 2 and 3 are not necessary to be built in within the housing main body 18 previously and they can be disconnected easily as the guide unit 8, so that the productivity and the maintainability of the device can be improved. Moreover, in this label printer 1, the guide base 5 of the guide unit 8 positioned within the housing main body 18 is supported between inner frames 21 and 22 by engagements of recessed grooves 15, 24 with guide pins 23, 16 so that the positioning of the guide base can be done without bolts for fastening.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to various printer devices that issue labels using continuous paper.

2. Description of the Related Art In a printer device using continuous paper, a pair of paper guides are arranged inside the main body housing to hold the continuous paper from both sides from the paper feed port of the main body housing to the printing section. Such paper guides are supported so as to be slidable toward and away from each other so as to accommodate continuous papers of different widths.

Problems to be Solved by the Invention In the printer device as described above, since the paper guide guides the continuous paper from the paper feed port to the printing section, printing can be performed satisfactorily.

Here, since the paper guide is slidably supported as described above, this support mechanism has a complicated structure. In the above-described printer apparatus, the paper guide supported by the support mechanism having such a complicated structure is assembled inside the main body housing, resulting in reduced productivity and maintainability.

Means for Solving the Problem A printer in which a pair of paper guides are disposed inside the main body housing and are supported so as to be able to slide toward and away from each other and hold continuous paper from both sides from the paper feed port of the main body housing to the printing section. In the apparatus, a guide unit which is a unitized paper guide was provided, and this guide unit was detachably attached to the paper feed port of the main body housing.

The paper guide is positioned within the main body housing by detachably attaching the guide unit, which is a unitized paper guide, to the paper feed port of the main body housing, so the paper guide can be fixedly assembled into the main body housing in advance. It can be easily attached to and detached from the main body housing as a guide unit.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 5. First, as illustrated in FIG. 1, a label printer 1, which is a printer device of this embodiment, has sheet guides 2 and 3, which are a pair of paper guides with a U-shaped cross section and an expanded paper feed side. , Tapping screws 6 and knurled screws 7 are mounted on the guide base 5 with the guide plate 4 attached to the rear surface.
The guide unit 8 is formed by being slidably attached to the guide unit 8. Here, in this label printer 1, the direction of the sheet guides 2 and 3 is regulated by the convex portion 9 formed on the bottom surface being engaged with two ribs 10 formed on the surface of the guide base 5. It is rib 10
The interval can be visually checked by the scale 11 formed in between. In this label printer 1, an optical sensor 12 is attached to one sheet guide 3.
As illustrated in FIG. 3, the connector cord 13 of this optical sensor 12 is connected to the guide base 5 through a slit 14.
It is located on the back of the .

Here, the guide base 5 has grooves 15 that are open at the front formed on both sides of the front end, and guide pins 16 protruding from both sides of the rear end.
Three bolt insertion holes 17 are formed at the lower edge. Further, in this label printer 1, three bolt holes 20 are formed at the lower edge of a rectangular opening 19 which is a paper feed port formed on the rear surface of the main body housing 18, and the rectangular opening 1
A guide pin 23 is provided protruding from the center of the inner surface of the internal frames 21 and 22 arranged on both sides of the frame 9, and a groove 24 which is open at the rear is formed at the rear edge.

As illustrated in FIG. 2, in this label printer l, when the guide unit 8 is inserted into the rectangular opening 19 of the main body housing 18, the groove 15 of the guide base 5 and the guide pin 16 are respectively inserted into the inside. frame 21
．． 22 guide pins 23 and grooves 24 and are supported between the internal frames 21 and 22, the guide plate 4 is fixed to the main body housing 1 with three bolts 25.
By fastening the guide unit 8 to the rear surface of the guide unit 8, the guide unit 8 is fixed to the main body housing 18.

In addition, in this label printer 1, as illustrated in FIGS. 4 and 5, the optical sensor 12 is a transmission type sensor 2.
It has a structure in which a reflective sensor 28 is built into the U-shaped frame 27 of 6. For example, a label sheet, which is continuous paper with continuous labels through perforations, is detected by the transparent sensor 26, and the backing paper The label sheet with a label pasted thereon is detected by the reflective sensor 28.

In addition, the guide unit 8 of this label printer l includes:
An interlocking mechanism (not shown) is provided that interlocks the approach and separation of the sheet guides 2 and 3 around the center line.

In such a configuration, this label printer 1 has the following functions:
For example, the label sheet is held from both sides by the sheet guides 2 and 3 of the guide unit 8 and guided to a printing section (not shown) in the main body housing 18, and printing is performed on each label detected by the optical sensor 12.

Here, in this label printer 1, the guide unit 8
The sheet guides 2 and 3 are positioned within the main body housing 18 by inserting the guide base 5 into the rectangular opening 19 and fixing the guide plate 4 to the main body housing 18. Therefore, in this label printer 1, the sheet guides 2 and 3 do not need to be assembled into the main body housing 18 in advance, and can be easily attached and detached as the guide unit 8, which contributes to improving the productivity and maintainability of the device. be able to. Moreover, in this label printer 1, the guide base 5 of the guide unit 8 located inside the main body housing 18 has grooves 15, 24 and guide pins 23, 16.
It is supported between the internal frames 21 and 22 by locking with the internal frames 21 and 22, and bolt fastening or the like is not required for its positioning. That is, in this label printer 1, the guide plate 4 located on the outer surface of the main body housing 18 is connected to the bolt 25.
Since the entire guide unit 8 is fixed simply by fastening the seat guides 2 and 3, the seat guide 2.3 can be positioned within the main body housing 18 with an extremely simple operation.

Effects of the Invention As described above, the present invention includes a pair of paper guides that are slidably supported in directions toward and away from each other and that hold continuous paper from both sides from the paper feed port of the main body housing to the printing section. In a printer installed in a printer, a guide unit that is a unitized paper guide is provided, and this guide unit is detachably attached to the paper feed port of the main body housing, so that the guide unit can be attached to the paper feed port of the main body housing. Since the paper guide is positioned within the main body housing, there is no need to install the paper guide fixedly into the main body housing in advance, and it can be easily attached to and removed from the main body housing as a guide unit, making it easier to manufacture equipment. This has effects such as being able to contribute to improvements in performance and maintainability.
