Abstract

PURPOSE:To maintain a sheet guide at a specified angle without the use of a stand and any other appropriate equipment by guiding a sheet with the sheet guide which is engaged with a sheet transport path, if the sheet guide opens a sheet introduction aperture. CONSTITUTION:When data is printed on a sheet 13, a sheet introduction aperture 16 and a sheet discharge aperture 7 are opened to transport the sheet 13. An engagement part 10 engages with a sheet guide 9, if the sheet introduction aperture 6 is closed. When the sheet guide 9 is used, a front cover 3 is opened so that the lower part opens to a specified width, and the sheet guide 9 is rotated inwardly so that the tip 9a becomes hooked to a hook part 6a at the lower end of the sheet introduction aperture 6. Subsequently, a guide surface 11 formed by the top of the sheet guide 9 is constantly aligned on a straight line with a sheet feed path 12 on a main printer system 2. Thus the sheet 13 can be introduced smoothly into the main printer system 2 using the sheet guide 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a desktop printer device that is connected to a personal computer, a word processor, etc., and prints out =1 calculation results and processing results.

(Prior Art) Various printer devices that are generally used as output devices for personal computers and the like are capable of manually feeding not only continuous paper but also cut sheets of normal paper size. FIGS. 7 to 9 show the case where a cut sheet is used in an ordinary serial printer device.

In FIG. 7, reference numeral 20 indicates a paper guide, and this paper guide 20 serves to guide a cut sheet (not shown) for printing to a paper insertion slot 21 at a predetermined insertion angle. As shown in FIG. 8, the main cover 22 is pivotally attached to the upper surface of the main cover 22, and is supported from the back side by a stand 23 so as to maintain a predetermined angle. Further, the lower end of this stand 23 is pivotally attached to the upper surface of the main cover 22, and when storing these, first the stand 23 is folded down onto the main cover 22, and as shown in FIG. The guide 2o is tipped backward to cover the stand 23.

(Problems to be Solved by the Invention) However, in the above-described printer device, in order to hold the paper guide at a predetermined angle, it is necessary to separately attach a stand or the like, which leads to an increase in the number of parts. Furthermore, in order to smoothly insert the cut sheets, the size of the paper guide must be large, and there is a problem that the printer main body cannot be made smaller because it is necessary to secure a space for accommodating the paper guide.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the problems of the above-mentioned conventional technology, and to incorporate the paper guide into a part of the printer body so that the paper guide can be held at a predetermined angle without using a stand or the like. The purpose of the present invention is to provide a printer device.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a method in which paper passes through a paper transport path formed inside a printer main body, and a paper transport path provided in the printer main body within the paper transport path A printer device that performs printing using a printing mechanism includes: a front cover whose upper end is rotatably attached to the printer body; a paper guide for opening and closing a paper insertion slot formed in the front cover; It is characterized by comprising a lid plate for opening and closing a paper discharge port bored at the rear, and the paper guide engages with the paper transport path to guide the paper when the paper insertion port is opened. It is something.

(Function) According to the present invention, the paper guide that opens and closes the paper insertion slot formed in the front cover engages with the paper transport path formed inside the printer body when the paper insertion slot is opened. Since the paper is guided by the paper guide, the printer device can be made more compact and the number of parts constituting the paper guide can be reduced.

(Embodiment) An embodiment of a printer device according to the present invention will be described below with reference to FIGS. 1 to 5.

In FIG. 1, reference numeral 1 indicates an upright type pull-up printer device. This printer device 1 includes a printer main body 2 which incorporates a printing mechanism including a thermal head etc. and a paper feeding mechanism, a rotatable front cover 3 whose upper part is pivotally attached to the front of this printer main body 2, and a It consists of a rear cover 4 that is integrally attached to the printer main body 2. The printer main body 2 incorporates the above-described printing mechanism and paper feeding mechanism, and is also provided with an operation panel 5 on the top surface for displaying status information and inputting operation information.

2 is a perspective view showing a state in which paper is inserted into the printer device shown in FIG. 1. FIG. The printer main body 2 is provided with a slit-shaped paper insertion opening 6 for feeding paper 13 into the printer body 2. A horizontally long opening 8 is formed in the center of the front cover 3, and a paper guide 9 of the same size is attached to this opening 8. This paper guide 9 is pivotally attached to the lower end of the opening 8 of the front cover 3 so as to rotate toward the paper insertion slot 6 side.

3 is a perspective view showing a state in which paper is ejected from the printer device in FIG. 1. FIG. On the rear cover 4,
A slit-shaped paper discharge port lower is provided for discharging the paper 13. A sliding cover plate 14 is attached to the lower end of the rear cover 4 to open and close the lower paper ejection port.

FIG. 4 is a side view of the printer device in FIG. 1.

When printing on the paper 13, the paper insertion port 6 and the lower paper ejection port are opened and the paper 13 is conveyed, as shown in FIG. The fitting portion 1o engages the paper guide 9 when the paper insertion slot 6 is closed. It is something to do.

When using this paper guide 9, as shown in Figures N2 and 4, open the front cover 3 so that the lower part has a predetermined width, and rotate this paper guide 9 inward. The leading end 9a is hooked to the hook portion 6a at the lower end of the paper insertion slot 6υ.

As a result, the guide surface 11 formed by the upper surface of the paper guide 9 and the paper feed path 12 of the printer main body 2 can always be placed in a straight line. Therefore, the paper 13 can be smoothly inserted into the printer main body 2 by the paper guide 9.

Further, a rear cover 4 is integrally fixed to the paper discharge port side of the printer device. The lower discharge portion of the rear cover 4 has a sliding cover plate 1 as shown in FIG.
4 is attached.

Figure M5 is a rear view showing the structure of the lid plate in Figure 3. As shown in FIG. 5, leaf spring-shaped guide pieces 15 are formed at both ends of the cover plate 14.
is held in a hole 16 formed on the inner surface of the rear cover 4. Therefore, the cover plate 14 can slide vertically along the groove 16, and can be maintained in an open state by the stopper 17 of the guide piece 15 such that the paper ejection lower is exposed as shown in FIG. .

Cut paper 13 is inserted into the printer device configured as described above.
The set state is shown in FIGS. 2 to 4.

At this time, although not shown, if a paper set piece for determining the position of the Qt form is placed on the surface of the paper guide, it is possible to prevent the paper from being inserted diagonally.

Although the printer apparatus in which the cover plate 14 is of a sliding type has been described above, the structure can be simplified by using a hinge type.

FIG. 6 is a side view showing a printer device according to another embodiment. By using a hinge type cover plate 14 as shown in FIG. 6, the paper ejection lower can be opened and closed with a simple structure.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the paper guide that opens and closes the paper insertion slot formed in the front cover is configured to transport the paper formed inside the printer body when the paper insertion slot is opened. Since it engages with the path and guides the paper, it is possible to reduce the manufacturing cost of paper guides, etc., and it is also possible to make the printer device more compact.
