Description

[Detailed Description of the Invention] This invention relates to a paper guide device for a printer.

Conventionally, printers that print on long sheets of paper are sometimes used to print by inserting cards or slips from the paper outlet as necessary, but cards and slips are equipped with a member to guide them. Since it is not printed, it bends and has the disadvantage of being extremely difficult to print on.

Further, passing a long sheet of paper after printing through the top surface of the casing not only spoils the aesthetic appearance but also requires care not to touch the exposed paper, which is troublesome.

This idea was developed in consideration of these points, and in printers that print on long sheets of paper, it is possible to eject the long sheet of paper to the rear of the casing without exposing it, and to prevent cards and slips from bending. It is an object of the present invention to provide a paper guide device for a printer that can print while printing and has a simplified structure.

This idea forms a drawer opening that extends toward the rear and upper part of the casing that houses the printer section, and divides the top cover that covers the printer section into two front and rear split covers, which can be used to print on long sheets of paper. By maintaining the split cover in a substantially horizontal position and ejecting the paper pulled out from the drawer port through the paper path formed between the rear split cover and the casing, the long paper is placed on the outer surface of the casing. When printing on cards, slips, etc. as necessary, place the split cover on an inclined surface that roughly matches the extended surface of the drawer opening, and place the split cover on the top surface of the split cover. This guides cards, slips, etc. from the drawer opening towards the printer section, thereby reliably preventing cards and slips from bending.Moreover, the split cover, which is part of the top cover, allows cards and slips to be guided from the drawer opening to the printer section. By providing a guiding effect for slips and the like, the structure is constructed so that an increase in the number of parts can be suppressed and the structure can be simplified.

An embodiment of this invention will be explained based on the drawings.
Casing 1 with a printer section (not shown) installed inside
is provided. A top cover 2 is provided on the top of the casing 1 to cover the printer section. Further, the casing 1 is formed with an outlet 3 that slopes toward the upper rear side. The top cover 2 is divided into two divided covers 4 and 5 with the outlet 3 as a boundary. The rear divided cover 5 is slidably attached to the casing 1 and holds long paper 6 such as folded paper or roll paper.
A window 8 is formed from which a guide 7 protrudes on both sides. Further, a certain space exists between the split cover 4 and the casing 1 in a horizontal state, and this space is used as a paper path for the long paper 6.

Thus, groove-shaped insertion portions 9 are formed on both sides of the casing 1, vertical stopper edges 10 are formed on the front edges of these insertion portions 9, and the outlet opening 3 and the inclined outlet 3 are formed on the rear edges thereof. A parallel stopper edge 11 is formed, and a hinge pin 12 is provided upright on the side surface of the insertion portion 9. On both sides of the split cover 5, there are formed an attachment arm 13 that slopes toward the lower front from the horizontal plane, and a protrusion 14 that is located near the attachment arm 13 at a part of the lower edge. The upper edges of these mounting arms 13 are formed with a contact edge 15 that contacts the stopper edge 10 and a contact edge 16 that is bent at an obtuse angle at the tip of this contact edge 15. An abutting edge 17 is formed in parallel to the abutting edge 15 and abutting against the stopper edge 11. Further, a long hole 18 is formed along the longitudinal direction of the mounting arm 13.

In such a configuration, when printing using a long sheet of paper 6, as shown in FIG. Pull it out through the inner surface of 5. In this state, the split cover 5
is supported by the upper surface of the casing 1 and the stopper edge 11, and its forward movement is regulated by the contact between the stopper edge 11 and the abutment edge 16, so that it is maintained in a horizontal state.

Also, as shown in FIG. 3, when printing on a cut sheet 19 such as a card or slip, the hinge pin
Rotate the split cover 5 around the center and slide the elongated hole 18 onto the hinge pin 12 while attaching the mounting arm 13.
into the insertion section 9. In this state, the stopper edge 10 and the abutment edge 15 are in contact with each other, the stopper edge 11 and the protrusion 14 are in contact with each other, and the upper surface of the divided cover 5 is located on the extended surface of the outlet 3. Therefore, the cut sheet 19 is guided by the upper surface of the split cover 5 and passes through the drawer opening 3.
It does not bend when inserted into the printer section, making it easy to print.

In this way, the cut sheet 19 can be guided using a part of the top cover 2, so the number of parts does not increase. Further, the structure for maintaining the divided cover 5 in an inclined state does not require any locking member. Therefore, the structure can be simplified, and if there is no locking member, the operation can be simplified accordingly.

In order to obtain the above-mentioned effect, hinge pins 12 are provided upright on the side surface of the mounting arm 13, and elongated holes 1 are provided to slidably hold the hinge pins 12.
8 may be formed perpendicularly to the side surface of the insertion portion 9.

Since this device is constructed as described above, when using a long sheet of paper, the sheet is exposed on the surface of the casing because it passes through the paper path formed between the horizontal split cover and the casing. This eliminates the risk of damaging the paper, improves its appearance, and allows the divided cover, which is kept approximately horizontal, to be maintained at an angle when printing on long sheets of paper. It can guide the insertion of cards, slips, etc. into the printer section, thereby preventing cards and slips from bending and making printing extremely easy.The guide function is also provided by a split cover that is part of the top cover. By using this, it is possible to suppress an increase in the number of parts and simplify the structure.
