A bearing (30) for a motor-driven winding shaft (28) for the printing medium is provided in the printer, the axis of rotation of which coincides with the pivot axis (38) of the pressure abutment (32).

Description

The invention relates to a printer comprising a printer kerchassis and an enclosing printer housing to accommodate at least one printing station with one print head, a print abutment assigned to the print head and a bearing for a supply roll of a web-shaped print carrier, between the printhead and platen is carried out, the pressure abutment by one Bearing axis of the supply roll parallel swivel axis between a printing position in which there is a Pressure gap for the print carrier, and one of the printing Service position far from the head can be swiveled in one Supply roll can be inserted into the printer.

A printer of the above type is for example known as a receipt printer for checkout stations. That pivots bare pressure abutment enables a quick insertion new supply roll without the print carrier, that is, over licher a paper web threaded into the nip must become what used to be disruptive interruptions of the Cash register operation.

In addition, journal printers are known in which the printing carrier not torn off but after printing on egg ner winding shaft is wound. With these printers the supply roll is usually axially on a shaft postponed. The print carrier web must then through the The pressure gap is threaded and connected to the take-up shaft  become. This is often time consuming and causes large ones Crowds at the checkouts undesirable operational disruptions.

DE 42 27 807 C2 shows a printer consisting of a Basic housing that contains a printhead and one Housing attachment, which is a pressure abutment, supply rolls for Receipt and journal print media and a take-up roll includes. The housing attachment is over a swivel axis between a service position and one on the base housing overlying pressure position pivotally mounted.

US 5 672 020 shows a printer consisting of a Basic housing that has a pressure abutment and a supply roll includes, a middle part for guiding the print carrier and a bowl-like housing attachment that holds the printhead includes. Housing attachment and middle part are over one common pivot axis between an open Service position and a closed pressure position pivotable.

The invention has for its object a printer Specify the type mentioned above, as a journal printer can be used and in which the print carrier supply roll can be inserted quickly and easily.

This task is performed on a printer of the type mentioned Art solved in that in the printer a bearing for a motor-driven winding shaft for the print carrier is provided, the axis of rotation with the pivot axis of the Pressure abutment coincides.

The proposed arrangement of the Winding shaft allows, as with the already known receipt  Printers to pivot the platen without doing so the take-up shaft is in the way. This can cause the pressure gap wide open and the supply roll for the print carrier web can be conveniently placed in their storage. The print carrier web will led around the pressure abutment and with the winding shaft connected. Threading the print medium into the print nip not necessary. The printer according to the invention is not only extremely simple and without the risk of malfunctions to use, but also easy to manufacture.

To a despite the pivotability of the pressure abutment To enable stable storage for this is Pressure abutment expediently on one of the printer chassis pivotally mounted frame arranged. Preferably the pressure abutment is parallel to the swivel axis Platen roller in its print position with a drive motor  can be coupled. So the write serves roller at the same time as a transport roller for the printing medium.

To simplify the arrangement, it is useful if the Winding shaft from the same motor as the platen roller can be driven. However, since the diameter of the wic kels on the take-up shaft increases continuously, the order catch speed at the winding of the take-up shaft, wuh rend the circumferential speed on the platen roller the same remains. In order to drive the whale at the same time ze and winding shaft to he by the same drive motor possible, it is proposed that the take-up shaft with the drive motor driving the platen via a Slipping clutch is coupled.

The printer housing expediently has a housing bottom part and a cover that is attached to the lower part of the housing lid axis parallel to the pivot axis pivotally mounted and between a closed position and an opening position lung is pivotable, in which he is replacing the front advice roll and the winding shaft and the pivoting of the Pressure abutment in its service position enabled. because at the operation of the printer can still combine be folded that the lid on one to its closing position adjacent part of its swivel path releasably with the pressure abutment is coupled so that this when ver swing the lid between its pressure position and its service position and vice versa. The Operator can therefore with a single movement Open the cover and at the same time the pressure abutment in his Swivel service position, so that not only the Aufwic shaft can be removed, but also the bearing exposed for the supply roll. In the same way  when closing the cover also the pressure abutment his service position back to the printing position swings.

The coupling between cover and pressure abutment can done in a simple manner so that on a lid-fixed Section at least one hook is formed on egg nem part of the cover swivel path one with the pressure resistor eng or section connected to the frame.

The printhead can be thermo in a manner known per se be printhead. Furthermore, a white can in the printer housing tere printing station with a printhead, a this arranged thrust abutment and a warehouse for a supply roll of a web-shaped printing medium, where both printheads can be controlled together. The two Printing stations can, for example, the receipt printer and the Form a printer's journal printer.

Features and advantages of the invention result from the following description, which in connection with the accompanying drawings, the invention based on an off management example explained. Show it:

Fig. 1 is a perspective schematic view of a divisional applications POS printer according to the OF INVENTION dung with the lid closed,

Fig. 2 shows one of Fig. 1 corresponding view of the POS printer to which the Jour naldrucker covering part is folded up the lid,

Fig. 3 is a schematic side view of part of the journal printing station with the lid closed,

Fig. 4 is a schematic representation le of the drive for the platen roller and the Aufwickelwel,

Fig. 5 is a view corresponding to Fig. 3 of the journal printing station with a half-open or half-closed lid and

Fig. 6 is a view corresponding to FIG. 3 of the journal printing station with the cover in the fully open position.

The printer shown in Fig. 1, generally designated 10 has a printer housing 12 with a lower housing part 14 , which contains a receipt printing station 16 and a journal printing station 18 and in the area of the receipt printing station 16 by a cover 20 and in the area of the journal printing station 18 by a Cover 22 is closed. On its front side, the printer housing 12 has a control panel 24 .

The receipt printing station 16 has, in a manner known per se, a print head, a pressure abutment and a bearing for a pre-roll of a printing medium and is not explained in more detail here. Fig. 2 shows the printer 10 with cover 22 open. You can see parts of the journal printing station 18 , namely a supply roll 26 for the web-shaped Druckträ ger and a take-up shaft 28 on which the web-shaped print carrier is wound after printing. On the winding shaft 28 is stored in open bearing forks 30 (of which only one can be seen in Fig. 2) of the printer chassis.

Furthermore, one recognizes a platen 32 in the form of a platen roller, which is not shown in FIG. 2 Ther associated with print head and is BEFE Stigt on a pivoting frame 34 . This has two mutually parallel frame spars 36 , which are pivotally mounted with their free ends remote from the platen roller 32 on the printer chassis about a pivot axis 38 co-axial with the axis of the winding shaft 28 in a manner not shown. The interaction of these parts of the journal printing station 18 will now be explained in more detail with reference to the schematic FIGS . 3 to 6.

Referring to FIGS. 3, 5 and 6 is based on the supply roll 26 for the printing carrier web 40 in a bearing recess 42nd The print carrier web 40 runs from the supply roll 26 via the platen roller 32 to the take-up shaft 28 . The platen roller 32 and the take-up shaft 28 are driven according to FIG. 4 by a common drive motor 44 via intermediate gears 46 , 47 . The drive of the take-up shaft 28 takes place via a slip clutch, not shown, in order to take into account the fact that the circumferential speed of the winding on the take-up shaft 28 changes with increasing winding diameter.

The cover 22 is pivotally mounted on the lower housing part 14 about a pivot axis 48 parallel to the pivot axis 38 of the frame 34 , so that it can be pivoted between its closed position shown in FIG. 3 and its open position shown in FIG. 6. A hook 52 with a hook opening 54 is formed near the front end of a side wall 50 of the cover 22 . If the cover 22 is pivoted from the opening position shown in FIG. 6 in the counterclockwise direction about the pivot axis 48 in the direction of its closed position shown in FIG. 3, it meets with a ramp surface 56 merging into the hook opening 54 against a shaft journal 58 of platen roller 32 ( Fig. 5). Upon further Ver pivot towards its closed position then takes the lid 22 to pivot frame 34 to the platen roller 32 and pivots the platen roller 32 in their in Fig. 3 shown printing position, bears in which they modruckkopf at a Ther 60th The platen roller 32 and the thermal print head 60 , which is tensioned by a spring 62 against the platen ze 32 , form a printing nip 64 through which the print carrier web 40 is passed.

If a new supply roll 26 is to be inserted or the printer has to be opened for another reason, the cover 22 is pivoted clockwise from the closed position shown in FIG. 3, and at the same time it also rotates the swivel frame 34 together with the writing roller 32 Swiveled clockwise into the service position shown in FIG. 5. In this position, the shaft journal 58 comes free from the hook opening 54 , so that the coupling between the swivel frame 34 and the cover 22 is released and the cover 22 from the intermediate position shown in FIG. 5 into the open position shown in FIG. 6 can be pivoted. In the service position of the swivel frame 34 , the print head 60 and platen roller 32 are widely separated. The bearing trough 42 and the winding shaft 28 are freely accessible. The take-up shaft 28 with the roll formed thereon can be removed from the bearing forks 30 and a new take-up shaft 28 inserted. Further, a new stock roll is loaded 26 into the bin tray 42 and the print carrier web 40 placed over the platen 32 and fixed to the take-up shaft 28 by, for example, an initial portion of the web up to the take-up shaft 28 is wound. It can be seen that these measures can be carried out completely freely and comfortably in the position of the parts shown in FIG. 6.
