Description

The present invention relates to a printer, in particular

  Link a portable office printer, consisting of subgroups arranged on a frame inside a housing. It is known to produce a printing device in a modular manner (patent DE-3 208 111). Such printers are constituted by a frame on which the guides are formed.

  necessary as channels of introduction and extrac-

  The subgroups are constituted, for example, by a printing station with a printing head and a stop. In addition, an ink ribbon cassette is provided. Other subgroups form a device. magnetic strip recognition system and a paper cutting device In this case, a device for transporting

  endless forms that can rotate or a unit of im-

  Pivotable pressure is also common An endless form transport device that can be rotated is used in a known manner in consideration of the requirement of

  accessibility in service and for proper maintenance.

  In truth, in this case, the printing unit together with the endless form transport device is lifted up, while the individual form transport device is made as a removable basic unit. The known printer presents

  thus separate paper tracks for indi-

  viduals in the base unit and for endless bands

in the liftable part.

  In the case where such a separation of the path of the individual leaves and the endless path is not planned, is not necessary or is not desired, the known division

  may also not be used.

  The present invention aims to provide a suitable printer for a plurality of documents, such as for example individual tickets, travel cards, invoices, checks, invoice control sheets, bundles, air tickets (as individual cards or bundles), tickets having bar codes, cargo documents, accounting documents, access cards, reservation cards, labels and the like, all of which may be produced individually or as an endless band In this case, printed objects that do not move properly must be able to be removed from the printer and the mouths of the channels

  paper should also be able to

  tints. For this purpose, the printer, in particular a portable office printer, consisting of subgroups arranged on a frame inside a housing, which form paper introduction and extraction channels by means of pairs

  of rollers, which also form at least one

  pressure, consisting, each time, of a print head,

  a stop, and an ink ribbon cassette, and pre-

  processing stations, such as for example a magnetic track recognition device and a paper cutting device, the housing being subdivided into a lower base structure and a liftable housing part, is remarkable, according to the invention, in in order to release the object to be printed, the lifting case part and the associated upper roll, in each case, to

  a lower roller mounted in the lower basic structure

  may be tilted, each time separated, as independent units, the unity of the

  lifting case part and the unit of the upper rollers

  which can be fixed in relation to the

  lower base structure or lower rollers.

  The advantages obtained by virtue of the invention consist in particular in that, for a common paper path for individual sheets, individual documents and endless belts, the advantage of proper operation and maintenance, however, remains preserved and, moreover, maintenance work, which must be carried out by the operators, such as the installation of the ink ribbon cassette, the elimination of

  waste paper and the like are facilitated.

  A particular advantage is that the introduction of all types of documents and their extraction takes place from one

  one and the same side of the printer.

  According to another characteristic of the invention, all the upper rollers that can be tilted are rotatably mounted on an arm pivotable about an axis extending horizontally at the end of the liftable housing portion, pivotally mounted. there are angular access spaces as well between the part of

  lifting case and the arm carrying the upper rollers

  on the one hand, that between the arm and the basic structure

lower, on the other hand.

  According to another characteristic of the invention, in the liftable housing part, there is provided a clean chassis of subgroups for fixing a scanner device, a printing unit with a print head, an ink ribbon cassette, and a cutting unit, as well as an ejection channel of the printed object This arrangement facilitates assembly and accessibility for the user, since the unwinding of the ink ribbon In addition, it is advantageous that, by tilting of the liftable housing part, as well as of the swivel arm with the upper rollers, free access to the housing structure is achieved.

lower base.

  Whereas, generally, in the known apparatuses, the electronic circuits are arranged in the lower base structure, it is proposed, in this case, that in the liftable housing part, at one end, is arranged a control plate Thus, we obtain a

  shortest possible link to the electronic subgroups

  In addition, a very high degree of integration between

  mechanical and electronic subgroups.

  According to yet another characteristic of the invention, inside the lower base structure or individual modules are arranged the motors for the lower rollers and the magnetic track recognition device, as well as the power supply. This measure ensures, firstly, for the lower basic structure, a necessary rigidity and, at the same time, the subgroups are distributed relatively evenly over the lower base structure and the part of

liftable housing.

  Advantageously, in the lower base structure, there is provided a pressure bar with flat abutment surface, close to the print head. Thus, there is a gap at a necessary distance from the other subgroups, to allow the association of individual subgroups

when the device is closed.

  The possibility of general use of paper brought manually and motorized is improved in that, directly on the closed upper housing part, being in the service position, is arranged a funnel

  with its own pair of rolls of trans-

  port and connecting to the lower base structure.

  Another improvement is that, below the feed funnel, a paper feed device for an endless printing object is arranged in the lower base structure. Thus, a feed side is obtained. unit, considered from the service side, for

the paper.

  According to another characteristic of the invention, for the processing of individual documents and / or an object to be printed without f in, coming from document reserves associated with each type of paper, at least one entry for the object to be printed. Motor-driven endless end and an entry for the motor-driven individual documents open at the beginning of a treatment plan, and either a horizontal entry for the individual documents, or a top entry for the individual documents brought manually or motorized way is provided, and the transport of different types of documents takes place on a

  treatment plan and in a direction of trans-

  port, and, outside the treatment plan, is provided a

  return the printed object in the opposite direction of the

  transport, and the printed object can be deposited in the operator's area, and a housing part can be

  noted, and with it, a plurality of

  is lying. According to yet another characteristic of the invention, the other input for the individual documents brought from

  motorized way is linked to the reserves of documents em-

  crushed on top of one another Depending on the height of

  of the printer, it is possible to obtain a reserve

  important of different documents to print.

  According to yet another characteristic of the invention, above the treatment plane, are arranged a printing unit, a scanner device, a reader of

  bars, and a cutting unit and, under the treatment plan,

  a magnetic track recognition device and a two-track bar code reader. All modular subgroups are thus easily exploited with respect to the different types of documents, and when unavoidable problems occur, the service personnel can easily intervene, thanks to the fact that the printer housing can be raised, for

solve these problems.

  The figures of the annexed drawing will make clear how

the invention can be realized.
