Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a mounting device for a soundproof cover of a printer used for printing devices such as electronic computers (including personal computers) and word processors. (B) Conventional technology Conventional printer devices can be roughly divided into three types: inkjet type, thermal type, and wired type.
There are two types of printers: the inkjet type and the thermal type, which are not pure mechanical types and therefore have few moving parts, so noise is not a problem, so there is almost no need for soundproofing measures. The noise generated during printing is large and cannot be put to practical use unless countermeasures are taken. Therefore, conventional printers have begun to use a soundproof cover that covers the printing head portion from above. However, when it comes to soundproof covers for printers that can use both continuous paper and single-sheet paper, it is particularly important to insert paper from the front for single-sheet paper, and from the rear for continuous paper. However, a soundproof cover that is convenient for both has not yet been devised. (c) Purpose of the invention The present invention eliminates the drawbacks of the conventional example described above regarding the wired-dot type soundproof cover for the conventional printer. With the soundproof cover,
The purpose of the present invention is to prevent the cover from slipping off when one of the two divided cover sections is opened when handling cut sheets and continuous sheets. (d) Structure of the invention This invention covers the upper surfaces of the front part of the printer and the rear part of the printer, and connects the first part with a hinge.
a lid part and a second lid part, an engagement hole that is engaged with a protrusion provided on the printer body and provided inward of the first lid part, and a protrusion provided on the printer. and a recess provided in the second lid part that fits into the second lid part. (E) Embodiment The drawings all show the soundproof cover mounting device for a printer according to the present invention, and FIG. 1 is a perspective view of the printer with the lid closed, and FIG. 2 is a perspective view of the printer with the first lid opened. FIG. 3 is a perspective view of the second cover with the second lid open. The present invention will be described below with reference to the drawings. In the drawing, 1 is the printer body, 2 is the soundproof cover, 3, 4
are the first lid part and the second lid part, 5,
Reference numerals 5, 6, and 6 each indicate a pair of protrusions and protrusions provided on the printer body 1 , 7, 7, and 8, and 8 respectively engage holes and recesses provided in the soundproof cover, 9 indicates a platen, and 10 and 11 indicate a pair of protrusions. a lever attached to the soundproof cover to move a paper presser rod (not shown) relative to the platen; 12, a platen rotation knob; 13;
13 is a mounting bracket, 14 is a sound absorbing material, and 15, 15 is a hinge. Next, a description will be given of how to attach a soundproof cover using the apparatus for attaching a soundproof cover for a printer according to the present invention. When the lever 10 is set to the state shown and the lid is closed, the state shown in FIG. 1 is obtained. In this case , the protrusions 5, 5 of the printer main body 1 and the engagement holes 7, 7 of the mounting brackets 13, 13 fixed to the first lid part 3 are connected to the protrusions 6, 6 of the printer main body 1 , and The recesses 8 and 8 of the lid part 4 of 2 are engaged and fitted, respectively, so that the printer body 1 is completely covered by the soundproof cover 2 , and the soundproof cover 2 is securely attached to the top surface of the printer body 1 . It can be placed and held and continuous paper can be used. On the other hand, when using cut paper, as shown in Figure 2,
When the first lid 3 is opened, a cut sheet is wound around the platen 9, and the lever 10 is tilted in the direction of the arrow A, the pressing rod is pressed against the platen 9, and the platen 9 is rotated. Ballots will definitely be sent. Next, when opening the second lid part 4 to perform work such as replacing the continuous paper, the second lid part 4 opens the second lid part 4 with the hinges 15, 15 as boundaries, as shown in FIG. 2
Push up the lid part 4 in the direction of arrow B. At this time, the engagement holes 7, 7 of the first lid part 3 are connected to the protrusions 5, 5.
The soundproof cover 2 is placed and held on the upper surface of the printer main body 1 . (f) Effects of the invention According to the invention, when installing a soundproof cover in a dot printer, with the first cover part or the second cover part of the two-part soundproof cover opened, It can be securely placed and held on the top surface of the printer main body, and accidents such as the soundproof cover slipping down can be prevented.
