Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a paper discharge guide device for a printer having a cutter. 6. Prior Art First, a conventional example is shown in FIG. 1 is a printing section, and this printing section 1 consists of a printing head 2 and a platen 3. A paper feed section 6 is provided below the printing section 1, in which a driving roller 4 and a driven roller 5 are in contact with each other, and a cutter 9, in which a fixed blade 7 and a movable blade 8 are opposed to each other, is provided above the printing section 1. It is provided. A top cover ti having an opening 10 that opens directly above the cutter 9 is provided above the cutter 9.

In this printer, predetermined content is printed on the long paper 12 in the printing section l.
, the long paper 12 is conveyed by the paper feed section 6, and the fixed blade 7
The movable blade 8 is slid to cut the long paper 12 and issue it as a ticket such as a receipt.

Problems to be Solved by the Invention Since the opening 10 of the top cover 11 opens directly above the print unit 1 and the cutter 9 which has rectangular holes 7a and 8a through which the long paper 12 passes, foreign matter cannot be removed from the opening 10. The rectangular hole 7a of the cutter 9 may be accidentally dropped or accidentally hit with a finger.

There is a danger of putting it in 8a.

Furthermore, when issuing a ticket such as a receipt, the user may hastily cover the opening 10 with his/her hand before cutting the long paper 12 with the cutter 9, which impairs the upward ejection operation of the long paper 12. Then, the long paper 12 becomes slack during the path from the paper feeding section 6 to the cutter 9, or when the long paper 12 is cut, a ticket is missed and the ticket falls from the rectangular holes 7a, 8a of the cutter 9, and this can occur. This may cause paper jams.

Means for Solving the Problem In a printer that uses a cutter to cut a long sheet of paper printed in a printing section and issues it as a ticket, the cutter is disposed above the printing section, and A cover having obliquely intersecting slopes and a ticket issuing opening opening laterally at the upper end of the slope is provided above the cutter.

The upper part of the working printing part and cutter is covered by a cover, which prevents foreign objects from falling into the cutter or printing part or accidentally touching the cutter with your fingers. The slope of the cover allows the cutter to be guided quickly toward the ticket issuing slot on the side.Furthermore, a cover is provided that faces the top of the cutter at a predetermined distance, and a cover is provided on the side of the cover in a substantially vertical plane. Provide a ticket issuing port that opens,
Contact the ticket along a straight line parallel to the width direction of the ticket at a position between the cutter and the ticket issuing opening and away from the cutter at a distance of one-half or less of the minimum unit length of the ticket. By providing a support section, the paper before being cut into a ticket is directed toward the ticket issuing port due to the curling tendency from being rolled as a long paper or due to the guiding action of the cover, but the long paper is supported. When the ticket is fed into contact with the paper cutter and cut into a ticket by the cutter, the supporting part allows the ticket to fall toward the ticket issuing slot and prevent it from falling directly above the cutter. Furthermore, by forming a space inside the cover that expands in the plane direction of the field and continuing to the ticket issuing opening, it is possible to cover the ticket issuing opening with your hand and eject the long paper. Even if the operation is impaired, the long paper can be loosened in the space downstream of the cutter, thereby preventing the long paper from loosening in the path upstream of the cutter and paper jams due to this slack. Furthermore, by rotatably supporting the cover by the fulcrum, even if uncut long paper accumulates in the space, the cover can be opened by the pressure of the long paper accumulated in the space. Therefore, it is possible to more effectively prevent the slack of the long paper in the path upstream of the cutter and paper jams caused by this slack, and furthermore, the guide surface in contact with the side edge of the ticket can be separated from the cutter and the cover. Even if the long paper is pulled in the width direction, the side edges of the long paper are supported by the guide surface to maintain the correct posture of the long paper in the conveyance path including the printing section. Further, a top cover having an opening facing the center of the cutter is provided on the top of the cutter so as to be openable and closable, a cover facing the top of the opening is provided on the top cover, and the cutter has the By providing a paper guide plate that protrudes upward from the opening, even if the top cover is blocked with a long paper protruding above the cutter, the paper guide plate prevents the long paper from falling and the top cover is closed. This makes it possible to avoid a situation in which the long paper gets caught.

Embodiment A first embodiment of the present invention will be described with reference to FIGS. 1 to 5. The parts explained in FIG. 12 are designated by the same reference numerals and their explanations are omitted (the same applies hereafter).

A frame body 13, which is open at the top and bottom, is fixed to the edge of the opening 10 of the top cover 11. Guide surfaces 14 that contact both side edges of the long paper 12 are formed on both sides of the frame 13, and a space 15 that expands in the surface direction of the long paper 12 is formed inside the frame 13. ing. Further, a cover 16 facing the upper part of the cutter 9 and covering the upper opening of the frame body 13 is rotatably supported by the frame body 13 by a fulcrum portion 17 having a horizontal rotation axis. Between the border 18 formed in the frame 13 and the free rotation end of the cover 16, there is a position displaced laterally from directly above the rectangular holes 7a, 8a of the cutter 9. A ticket issuing opening 19 is formed which opens in a substantially vertical plane. Further, a ticket 12a having a minimum unit length between the rectangular holes 7a, 8a of the cutter 9 and the ticket issuing port 19 is provided.
A supporting portion 20 that contacts the note 12a along a straight line parallel to the width direction of the note 12a is connected to the boundary portion 18 at a position away from the cutter at a distance of less than half of .

In such a configuration, the printing unit 1 prints predetermined content on the long paper 12, the paper feeding unit 6 transports the long paper 12, and the cutter 9 cuts the long paper 12 as a ticket such as a receipt. Issue.

At this time, since the upper portions of the printing section 1 and the cutter 9 are covered by the cover 16, it is possible to prevent foreign objects from falling onto the cutter 9 and the printing section 1, or from accidentally touching the cutter 9 with a finger. In addition, the ticket 12a cut by the cutter is directed toward the ticket issuing port 9 due to the curling tendency left when it was rolled as a long paper or by the guiding action of the cover 16, but as shown in FIG. When the long paper 12 is fed in contact with the support section 20 and cut into a ticket 12a by the cutter 9, the support section 20 tilts the ticket 12a toward the ticket issuing port 19 to prevent it from falling directly above the cutter. be able to. This is because the distance from the rectangular holes 7a, 8a of the cutter 9 to the support portion 20 is shorter than one half of the length of the minimum unit ticket 12a.

This eliminates one cause of paper jams.

Furthermore, since a space 15 is formed inside the cover 16 that expands in the plane direction of the ticket 12a, as shown in FIG. Even if the operation is impaired, the long paper 12 can be loosened in the space 15 on the downstream side of the cutter 9, and thereby the long paper 12 can be loosened in the path upstream (downward) of the cutter 9. Paper jams due to looseness can be prevented.

Furthermore, by rotatably supporting the cover 16 by the fulcrum part 17, as shown in FIG.
The cover 16 can be opened by the pressure of the long paper 12 accumulated at the cutter 9, and therefore, loosening of the long paper 12 in the path upstream of the cutter 9 and paper jams caused by this slack can be more effectively prevented. can.

Furthermore, by providing a guide surface 14 that contacts the side edge of the ticket 12a between the cutter 9 and the cover 16, the long paper 12
Even if the long paper 12 is pulled in its width direction, the side edges of the long paper 12 are supported by the guide surfaces 14, and the posture of the long paper 12 in the conveyance path including the printing section 1 can be maintained correctly.

Next, a second embodiment of the present invention will be described based on FIGS. 6 and 7. A top cover 11 having an opening IO facing the cutter 9 is rotatably held around a fulcrum 11a. Although the long paper 12 has a tendency to curl in the direction of falling toward the ticket slot 19 side, a paper guide plate 21 that protrudes upward from the opening 10 of the top cover 11 and supports the long paper 12 is provided at the top of the cutter 9. It is being

Therefore, the same effects as in the embodiment described above can be obtained. Furthermore, since the long paper 12 is supported by the paper guide plate 21 and does not fall down, when the long paper 12 closes the open top cover 11 with the long paper 12 protruding above the cutter 9, the opening of the long paper 12 is prevented from falling. It is possible to avoid a situation where the long paper 12 is caught between the edges of the opening of the section 10.

Furthermore, a third embodiment of the present invention will be described based on FIGS. 8 to 11. A support plate 22 fixedly provided on the top of the cutter 9 has a cover 23 that covers the opening 10 of the top cover 11 and a slit hole 24 formed therein.

This cover 23 has a slope 25 that intersects with the vertical plane passing through the rectangular holes 7a and 8a of the cutter 9 upward to the left, and a ticket issuing port 26 that opens at the upper end of the slope 25.
A plurality of ribs 27 are formed rising from the side edge of the slit hole 24 and extending along the slope 25.

Therefore, the long paper 12 protrudes from the slit hole 24, is bent laterally by the ribs 27, and further guided to the ticket issuing port 26 along the slope 25. Therefore, as shown in FIG. 9, when the long paper 12 is cut with the cutter 9, the ticket 12
a will not fall below the slit hole 24. Furthermore, as shown in FIG. 10, if you are too conscious of taking out the issued ticket quickly and put your finger on the upper edge of the ticket issuing slot 26, the leading edge of the long paper 12 will come into contact with your finger. Also, the middle part protrudes outside the ticket issuing port 26. Thereby, the long paper 12 does not become loose between the printing section 1 and the cutter 9, thereby preventing jamming. Furthermore, since the ticket issuing opening 26 of the cover 23 opens laterally with respect to the vertical line passing through the cutter 9, it is possible to prevent foreign objects from falling and to avoid the risk of touching the cutter 9 with one's fingers.

Effects of the Invention As described above, the present invention is a printer that uses a cutter to cut a long sheet of paper printed in a printing section and issues it as a ticket. By providing a cover above the cutter, which has a slope diagonally intersecting the surface and a ticket issuing port opening laterally at the upper end of this slope, the upper part of the printing part and the cutter are Since it is covered by a cover, it is possible to prevent foreign objects from falling into the cutter or printing area, or from accidentally touching the cutter with one's fingers.In addition, the slope of the cover prevents foreign objects from accidentally touching the cutter. Further, a cover is provided which faces the upper part of the cutter at a predetermined distance, and a ticket issuance port which opens in a substantially vertical plane is provided on the side of this cover. A support that contacts the ticket along a straight line parallel to the width of the ticket at a distance between the cutter and the ticket issuing opening and away from the cutter at a distance of one-half or less of the minimum unit length of the ticket. By providing the supporting section, the paper before being cut into a ticket is directed toward the ticket issuing port because the curling tendency from being rolled as a long paper remains or due to the guiding action of the cover. When it is sent in contact with and cut into a ticket with a cutter,
The support part allows the ticket to fall toward the ticket issuing slot side and prevent it from falling directly above the cutter. This eliminates one cause of paper jams. By forming a space that expands in the plane direction and continuous with the ticket issuing port, even if the ticket issuing port is covered with your hand and the ejection operation of the long paper is impaired, the space in the downstream device of the cutter is The long paper can be loosened, thereby preventing the long paper from loosening in the path on the upstream side of the cutter and paper jams due to this loosening.Furthermore, the cover can be freely rotated by the fulcrum. By supporting the cover, even if uncut long paper accumulates in the space, the cover can be opened by the pressure of the long paper accumulated in the space, and therefore the long paper in the path upstream of the cutter By providing a guide surface between the cutter and the cover that contacts the side edges of the ticket, it is possible to more effectively prevent paper jams caused by the slack of the paper. Even if the paper is pulled, the side edges of the long paper are supported by the guide surface to maintain the correct posture of the long paper along the conveyance path, including the printing section. A top cover having opposing openings is provided so as to be openable and closable, a cover facing the top of the opening is provided on the top cover, and the cutter is provided with a paper guide plate protruding upward from the opening. Even if the top cover is closed with a long piece of paper protruding upward, the paper guide plate can prevent the long piece of paper from falling down, thereby preventing the long piece of paper from being caught by the top cover. It has the effect of being able to.
