Abstract

PURPOSE:To enable a plurality of kinds of recording papers differing in width to be accurately fed without generating skewing or the like, by providing a paper guide of a paper feeder with a guide part according to different paper widths. CONSTITUTION:A guide member 9 is provided with bases 10, 10 on the lower surface thereof, while a paper guide 5 is provided with a plurality of pairs of fitting holes 5a-5c for the bases 10, 10 in correspondence with paper widths. Accordingly, by changing the fitting position of the guide member 9, the distance from a guide frame 6 or 7 to the guide member 9 can be changed, so that a recording paper can be accurately guided according to the width thereof without generating skewing or the like, and a plurality of kinds of recording papers differing in width can be used.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer, and more particularly to a printer equipped with a paper feeding device capable of feeding recording paper of different paper widths.

[Summary of the Disclosure] This specification and drawings describe a printer equipped with a paper guide that feeds recording paper and a paper feeding device that feeds the recording paper to the platen side, in which multiple types of guides are provided on the paper guide side according to the width of the recording paper. This invention discloses a technique that can reliably feed multiple types of recording paper having different paper widths by providing a set of paper sheets.

[Prior Art] FIG. 4 shows a paper feeding device portion of a conventional printer.

In FIG. 4, the reference numeral 1 indicates a platen, which is illustrated as being divided into three parts in the axial direction in this example.

The platen 1 is rotatably supported between side plates 11 and 12 on the left and right sides of the paper press plate 2, and a platen knob 1a is provided at one end of the platen on the outside of the side plates.

Paper feed rollers 3, 3 are rotatably provided at the bottom of the platen 1, and a pinch roller 4.4 is in contact with these paper feed rollers 3.3.

The pinch rollers 4, 4 are arranged on the outside of the paper press plate 2, and pass through the opening 2a formed in the paper press plate 2 to the paper feed roller 3.
It is in contact with

Further, a paper guide 5 is arranged behind the platen 1, and guide frames 6, 7 are provided at both ends of the paper guide 5.
is located.

When feeding recording paper (not shown) using the above structure, the recording paper is positioned above the paper guide 5, and both ends of the recording paper are placed between the left and right guide frames 6, 7 and the paper guide 5. The paper is pinched and fed, passes between the paper feed roller 3 and the pinch roller 4, and is sent to the platen l side by the paper feed force of the paper feed roller 3.

[Problems to be Solved by the Invention] However, if the paper width of the recording paper becomes smaller than the distance between the left and right guide frames 6 and 7, there is nothing to support both ends of the recording paper, and the paper cannot be fed normally. There was a problem.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention adopts a structure in which the paper guide portion is provided with guide portions corresponding to a plurality of types of paper widths.

[Function] By employing the above-described structure, it is possible to use any one guide section according to different paper widths, and it is possible to accurately feed a plurality of types of recording paper having different paper widths.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

[First Embodiment] FIGS. 1 and 2 illustrate a first embodiment of the present invention. In each figure, the same parts as in FIG. 4 are given the same reference numerals, and their explanation will be omitted.

In this embodiment, a groove 8 which is one step lower is provided in the middle of the paper guide 5.

The width of this groove 8 is formed to match, for example, the width of a postcard or the like.

By providing such grooves 8, it is possible to provide guide portions for recording sheets of different paper widths, and it is possible to accurately feed the sheets without causing skew or the like.

In addition, in the embodiment described above, the groove 8 constituting the guide portion
Although the example in which only one is formed is shown, for example, A4.
If a plurality of stepped grooves are formed to match the paper width such as B5, it can be applied to a plurality of types of recording papers with different paper widths.

With this structure in which stepped grooves are provided in accordance with the width of the paper, the curvature of the recording paper inserted into the grooves is reduced, making it possible to print on stiff postcards and the like without difficulty.

Furthermore, since the paper guide having the groove can be integrally molded using a mold or the like, the structure is simplified and assembly is greatly facilitated.

[Second Embodiment] FIG. 3 illustrates a second embodiment of the present invention, and this embodiment employs a structure in which a detachable guide member 9 is provided as a guide portion.

That is, the guide member 9 has legs 10.10 on its lower surface, and a plurality of sets of two fitting holes 5a to 5C into which the legs 10.10 are fitted are provided on the paper guide 5 side in accordance with the width of the paper. - If such a structure is adopted, the distance from the guide frame 6 or 7 to the guide member 9 can be changed by changing the mounting position of the guide member 7, and the recording paper can be guided according to the paper width. , multiple types of recording paper with different paper widths can be used.

[Effects] As is clear from the above explanation, according to the present invention, the structure in which the paper guide of the paper feeding device is provided with guide portions corresponding to different paper widths is adopted, so that it can be used for a plurality of types of different paper widths. Recording paper can be used, and the recording paper can be fed accurately without causing skew or the like.
