Continuous paper feeding mechanism for printers with a pair of drive mechanisms on the paper delivery side of the platen. The drive mechanism can move parallel to the platen. Make its position match the width of the continuous paper. The drive mechanism also has a pair of guide members provided on the paper supply side of the platen. These guide members are in contact with the side edges of the paper and move together with the driving mechanism to feed the paper.
Description
The present invention relates to a paper feed mechanism for printing on continuous paper by a printer. More particularly, the present invention relates to a paper feed mechanism for preventing a deviation of a continuous paper fed by a single tractor-type driving mechanism in a printer.
The composition of a paper feed mechanism of a conventional printer using continuous paper is shown in fig. 1.
The mechanism has a platen 1 and a print head 7, and a pair of driving mechanisms 3 are disposed on the paper-feeding side of the platen 1, that is, in the upper portion. The device 3 has a drive pulley slidably arranged on the drive shaft 9, a guide pulley rotatably and slidably arranged on the guide shaft 10, and a closed rubber belt wound around these drive and guide pulleys. A set of tabs 6 are disposed on the outer surface of the strap at predetermined intervals. The tabs 6 engage with perforations 5 formed along both sides of the continuous sheet 2. When the shaft 9 rotates, the belt moves to feed paper upward.
A guide mechanism for guiding the paper 2 is disposed on the paper supply side of the platen 1. The guide mechanism has a guide shaft 8 arranged in parallel with the platen roller 1, and a pair of guide rollers 4 axially movably and rotatably arranged on the shaft 8.
The paper sheet 2 has various forms, which have different widths. When a sheet of one type is exchanged for another, the device 3 is moved axially until the lugs 6 are inserted into the perforations 5 of the sheet 2. The roller 4 is moved axially until the roller contacts the edge of the sheet.
In order to adapt the position of the drive mechanism and the guide roller to the width of the paper, it is necessary to place the device and the guide roller in a plane perpendicular to the platen 1. If this is not the case, it is unavoidable to feed the paper obliquely to the platen, as a result of which the printed lines are tilted or the words are printed out of the paper.
As such, the positions of these mechanisms and guide rollers are adjusted by the user so that they are not always precisely positioned and thus do not eliminate the drawbacks noted above.
An object of the present invention is to provide a paper feeding mechanism capable of accurately guiding a platen to a continuous sheet.
Another object of the present invention is to provide a paper feed mechanism capable of adjusting the positions of the driving mechanism and the guide mechanism to accommodate the width of the continuous paper used.
The paper feeding mechanism of the present invention causes the driving mechanism provided on the delivery side of the platen and the guide member provided on the supply side of the platen to be interlocked in a predetermined positional relationship, and according to an embodiment of the present invention, these guide members for guiding the continuous paper are connected to the mechanism. Thus, when the mechanism is moved, these are guide members are also moved. The mechanism and the guide members are always arranged in a plane perpendicular to the axis of the platen. They guide the continuous sheet vertically to the platen. In order to adjust the position of the mechanism and the guide members, it is sufficient to move the drive mechanism only.
The invention will be more apparent from the description of the embodiments in connection with the accompanying drawings.
Fig. 1 is an oblique view of a conventional paper feeding mechanism as seen from the rear side.
Fig. 2 is a simplified perspective view of a printer employing an embodiment of the present invention.
Fig. 3 is an oblique view of a paper feeding mechanism according to the first embodiment of the present invention as seen from the rear side.
Fig. 4 is a side view of the paper feed mechanism shown in fig. 3.
Fig. 5 is an oblique view from the rear side of a paper feeding mechanism according to a second embodiment of the present invention.
Fig. 6 is an oblique view from the rear side of a paper feeding mechanism according to a third embodiment of the present invention.
Fig. 7 is an oblique view from the rear side of a paper feeding mechanism according to a fourth embodiment of the present invention.
Fig. 2 to 4 show a first embodiment of the present invention. Fig. 2 shows a printer, and fig. 3 is a view from the rear side of a paper feeding mechanism according to the present invention.
In this figure, the printer includes a frame 21 and a cover 22, and a print head 23 is mounted on a carriage (not shown). The continuous paper 25 is fed along the peripheral surface of the platen 24 and printed by the print head 23. A plurality of perforations 26 for feeding a continuous sheet are formed at a predetermined pitch along both sides of the sheet 25.
The drive shaft 29 and the guide shaft 30 are disposed on the paper delivery side of the platen 24, that is, on the upper part of the printer. The shafts are arranged parallel to each other and to the axis of the platen 24. A pair of drive mechanisms 28 are supported on shafts 29 and 30. The shaft 29 is turned intermittently by a driving device (not shown) to print one line at a time.
The mechanism 28 includes a drive pulley, a guide pulley, side plates 33 and a closed rubber band 32 wrapped around between the wheels. A plurality of protrusions 35 are provided at predetermined intervals on the outer surface of the belt 32. The spacing of the tabs 35 is equal to the spacing of the perforations 26 on the paper 25. The drive pulley rotates together with the shaft 29 and is movable in the axial direction of the shaft 29, and the guide pulley rotates together with the shaft 30 and is movable in the axial direction of the shaft 30.
The tab 35 is inserted into the perforation 26 of the sheet 25. When the shaft 29 rotates, the belt 32 is driven, thereby intermittently feeding the paper 25.
A guide shaft 43 is provided on the paper supply side of the platen 24, that is, behind the platen 24 in the present embodiment, the guide shaft 43 being arranged parallel to the platen 24. The sheet 25 fed from a sheet storing portion (not shown) is guided by the upper surface of the shaft 43 and fed into the platen 24.
One end of these guide members 40 are attached to the side plates 33 of the mechanism 28 with screws 31, respectively. The member 40 is formed in a flat plate shape. The member 40 extends through above the platen 24 to a shaft 43. Through holes are cut in the guide ends 41 of these members 40 and guide bushings 42 are provided in connection therewith, so that shafts 43 are loosely inserted in the holes and the guide bushings 42. Thus, the member 40 can move in the axial direction of the lever 43.
The mechanism 28 and the end 41 of the member 40 lie in a plane perpendicular to the axis of the platen 24. More precisely, the end 41 of the member 40 and the mechanism 28 are positioned so that when the lug
The present invention is not limited to the embodiments described above, but various changes and modifications can be made within the spirit and scope of the present invention.
