Definitions

  • the present invention essentially relates to a compact printer having reduced dimensions, in particular as regards its depth thanks to special arrangements made at the level of the routing of the paper inside the printer.
  • a printer with "Background Journal” means that the printer is supplied with paper continuously from the outside from a feed store containing a load of zigzag folded paper for example.
  • Such a printer can also be designed to do sheet-by-sheet printing, but with a different paper insertion than that previously described. This insertion is done either in a vertical plane or in a horizontal plane, thus justifying the above expressions: printers with "Background Journal” and vertical insertion, printers with "Background Journal” and horizontal insertion.
  • the sheet of paper is introduced through an opening located on the upper face of the printer and exits, after printing, either through this same opening or through an opening provided on the lower surface of the printer. 'printer. Between the introduction and the evacuation of the sheet of paper, it always remains in the same vertical plane.
  • the abovementioned openings are located at the side surfaces of the printer, and the sheet of paper always remains in the same horizontal plane.
  • the invention aims to overcome these drawbacks by proposing a compact printer which no longer requires large clearance areas around the printer while allowing its dimensions to be reduced.
  • the invention therefore provides a compact printer comprising at least: a print head; an inlet opening for inserting a sheet of paper to be printed; an outlet opening for discharging the sheet of paper after printing; an automatic system for driving and guiding the sheet of paper inside the printer and defining a predetermined path to be followed by the sheet of paper between the inlet opening and the outlet opening characterized in that that it also includes means for bending the sheet as it advances inside the printer, these means being located in the aforementioned path beyond the print head in the direction of driving the sheet of paper, to keep entirely inside the printer said sheet of paper throughout its printing.
  • the insertion of the sheet of paper is done in a horizontal plane.
  • Such a printer therefore has an important advantage which lies in the fact that it is possible to make it more compact than any other known printer for a given length of paper.
  • Such a printer is therefore easy to install and can in particular be placed in abutment or against a vertical wall.
  • the printer (1) has all of its elements housed inside a case or casing (2).
  • the lateral surface (2a), hereinafter referred to as the front face, has an inlet opening (3) such as a horizontal slot.
  • this inlet opening (3) also plays the role of outlet opening.
  • An automatic system (4) for driving and guiding sheets of paper (P) is mounted inside the printer (1) and has the function of driving and guiding each sheet of paper (P) to inside the printer (1) during printing.
  • a predetermined path is thus defined along which each sheet of "-paper (P) moves inside the printer (1).
  • the system (4) consists for example of a horizontal support surface (5) or insertion plate located in the extension of the inlet opening (3).
  • the insertion plate (5) advantageously extends on either side of the inlet opening (3) as shown on the drawing.
  • the insertion plate (5) is associated on the one hand, with a drive device (6) consisting for example of friction rollers (7) and on the other hand, with a lateral guide device (not shown) on at least one side of the sheet of paper (P) to be printed.
  • the drive device (6) is for example a simple drive consisting of two pairs of friction rollers, each pair consisting of two rollers (7a, 7b) superimposed and between which passes each sheet of paper (P) to be printed.
  • the rollers (7a, 7b) are respectively supported by two horizontal axes (8a, 8b) arranged perpendicularly to the direction of paper drive, one of the two axes being motor.
  • the two pairs of rollers (7a, 7b) are respectively located towards the two lateral edges of the sheets of paper (P) to be printed.
  • the drive device (6) can be a double drive with, in addition to the two pairs of rollers (7a, 7b), two other pairs of friction rollers (9a, 9b) supported by two axes (10a, 10b).
  • the first pair of rollers (7a, 7b) is positioned towards the end of the insertion plate (5) located inside the printer (1), while the second pair of rollers (9a, 9b) is positioned between the inlet opening (3) and the first pair of rollers (7a, 7b).
  • a print head (12) positioned between the two pairs of rollers (7a, 7b; 9a, 9b).
  • each sheet of paper (P) is kept entirely inside the printer (1) throughout its printing.
  • means (13) forming a guide are provided for bending each sheet of paper (P) as it advances inside the printer (1), these means (13) being located in the above-mentioned path beyond the first pair of rollers (7a, 7b) in the direction of the sheet feed (P).
  • These means (13) are for example constituted by two guide surfaces (13a), (13b) parallel and curved between which is inserted each sheet of paper (P). These two surfaces constitute a guide or a clearance path for the sheet (P).
  • the sheet of paper (P) to be printed does not remain in the same horizontal plane inside the printer (1) all along of his impression.
  • the length of the clearance path is a function of the maximum size of the sheets of paper (P).
  • the direction of entrainment of the sheet of paper (P) must be reversed in order to eject it, once printed, through the inlet opening (3) which also plays the role of opening. Release. Under these conditions, the sheet of paper (P) is not completely exposed in the guide (13), the end of the sheet or bottom of the sheet printed last remaining in engagement with the rollers in friction (7a, 7b) .
  • the guide (13) is extended, as shown in dotted lines in the drawing, until it opens onto the front face (2a) of the printer (1) through an opening (14), this opening can then play the role of exit opening for the sheets of paper (P).
  • the sheet of paper to be printed has a length at least equal to the length (L) of the guide (13). In this case, it is not necessary to reverse the paper feed direction to ensure its ejection.
  • outlet opening (14) is provided above the inlet opening (3), but obviously it could be provided below.
  • Such a printer imposes only one clearance surface at its front face, which facilitates its installation and its use. This advantage is precious, in particular in the use of this type of printer in counters for example.
