Abstract

PURPOSE:To prevent the part of a paper discharged from a casing from falling down, make printed images easy to see, omit paper stands and facilitate handling, by a construction wherein a paper is bent in the direction orthogonal to the feeding direction thereof, between a paper rest provided at an opening and a prt of the rear end of a sound-insulating cover. CONSTITUTION:At the opening 5 provided in an upper face of the casing 1, the paper rest 7 is immovably provided to prevent parts of the paper 6 from overlapping with each other and support the paper 6 fed from a platen 3 while ascending rearward. A transparent sound-insulating cover 8 for covering the opening 5 is openably fitted to the casing 1 through hinges 9, and the rear end edge thereof is provided with a guide surface 10 ascending rearward and opposed to the paper rest 7 with a predetermined gap therebetween. Accordingly, since the paper 6 is curved by curved surfaces 11, 12, it is prevented from falling down rearward in a predetermined range in the discharging direction thereof from the cover 8, and the printed images can be easily seen.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a paper guide device for a printing machine.

Technical Background of the Invention and Problems Therein Generally, in printing machines such as typewriters, a paper stand is provided at the rear of the housing that slopes backward upwards, and the paper that has been printed and discharged is supported on the paper stand to display the printed content. has been confirmed. Without this paper stand, the paper would fall over and it would be difficult to see what was printed. Therefore, the paper stand is useless unless it has a length that protrudes from the top of the casing. In recent years, there has been a strong demand for printing machines to be smaller and lighter, and in that sense paper stands are inconvenient and obstructive for portability. A removable and foldable paper stand has also been devised, but users have to purchase a paper stand just to view the printed content, which makes handling the paper stand that much more cumbersome.

Purpose of the Invention The present invention was made in view of the above points, and an object of the present invention is to provide a paper guide device for a printing machine that allows the printed content to be easily confirmed and also allows the paper stand to be omitted. That is.

SUMMARY OF THE INVENTION This invention curves paper in a direction perpendicular to its feeding direction between an erasure plate provided in an opening of a housing and a part of the rear end of a soundproof cover. This structure prevents the part that is expelled from the body from falling over, making it easier to see the printed content, and also simplifies handling by omitting the paper stand.

Examples of the invention An embodiment of the present invention will be described based on the drawings.

(1) is a housing. Inside this housing (1) is a printing mechanism (4) whose main components include a carrier (2) on which a print head is mounted and a platen (3). An erasure plate (7) is fixedly provided in the formed opening (5) to prevent the sheets (6) from overlapping and to support the sheets (6) sent backward and upward from the platen (3). In addition, a transparent soundproof cover (8) that covers the opening (5) is attached to the housing (1) so that it can be opened and closed by a hinge (9), and an eraser plate is attached to the rear edge of this soundproof cover (8). A guide surface αO facing (7) with a predetermined gap is formed so as to be inclined rearwardly upward. Thus, a curved surface 01) Q curved in one direction perpendicular to the feeding direction of the paper (6) is formed on both surfaces of the guide surface (10 and the erasure plate (7) facing each other). As long as the curved surfaces 0902 are parallel so that the gap between the curved surfaces 0909 does not change significantly, the relationship between the curved unevenness is such that the curved surface curves downward toward the center as shown in FIGS. It may be either one that curves upward toward the center as shown in the figure, or one that curves in a waveform as shown in FIG. 7. Also, paper (6) is placed between the curved surface Ql)02.
In order to be guided smoothly, the edge Oj of the guide surface 01 on the platen (3) side and the edge 04 of the eraser plate (7) on the platen (3) side are aligned in a straight line parallel to the axis of the platen (3). , and the degree of curvature increases toward the rear from the edge αIQ4.

In this configuration, the paper (6) sent rearward upward by the platen (3) is curved by the curved surface α°C02, so that the sheet (6) is sent rearward at least for a certain range from the soundproof cover (8) toward the ejection direction. It will not fall down and lie on the top surface of the casing (1). Therefore, the printed content can be made extremely easy to see. Even if the length of the opposing surface between the guide surface 00 and the eraser plate (7) in the paper feeding direction is short, the paper (6) can be curved. Furthermore, since the paper stand can be omitted, the device can be made more compact and the handling can be simplified.

Effects of the Invention Since the present invention is configured as described above, the erasure plate and the soundproof cover can prevent the paper ejected from the housing from falling over, and therefore, the printed content can be made easier to see. , the paper stand can be omitted, the structure can be simplified, and handling can be simplified.
