Opfindelsen angår en printer til udprintning af ark eller baner, og af den art, der har en kasse, hvori printerens bestanddele er anbragt. Formålet med opfindelsen er, at nedsætte støjen fra printeren.The invention relates to a printer for printing sheets or webs and of the kind having a box in which the components of the printer are arranged. The object of the invention is to reduce the noise from the printer.

5 En printer omfatter mekaniske organer, der er i bevægelse og afgiver støj, samt elektriske eller elektroniske, varmeafgivende komponenter. Varmen bortledes gennem ventilationsåbninger i printerens kasse. Imidlertid føres støjen også ud gennem disse åbninger 10 og kan derfor genere omgivelserne.5 A printer includes mechanical means that are moving and emitting noise, as well as electrical or electronic, heat-emitting components. The heat is dissipated through ventilation openings in the printer box. However, the noise is also discharged through these openings 10 and can therefore bother the surroundings.

Opfindelsen tager sigte på at afhjælpe disse u-lemper og giver anvisning på en udformning af printeren, hvorved støjen fra de i funktion værende mekaniske organer forhindres i at føres ud, medens den fornødne 15 udluftning for de elektriske eller elektroniske komponenter sikres.The invention aims to remedy these drawbacks and provides a design of the printer, thereby preventing the noise from the functioning mechanical means from being discharged while ensuring the necessary ventilation for the electrical or electronic components.

Med henblik herpå er en printer ifølge opfindelsen ejendommelig ved, at kassen er således indrettet, at der er dannet to separate, indbyrdes støjmæssigt 20 isolerede kamre, at det ene kammer rummer de støj givende, mekaniske organer og er afgrænset af kasseflader uden anden åbning end en indgangsåbning for det printbare materiale og/eller en udgangsåbning for det udprintede materiale, og at det andet kammer rummer de 25 navnlig elektriske og elektroniske varmeafgivende komponenter og er afgrænset af kasseflader, der kan være udformede med udluftningsåbninger til bortledning af varme.To this end, a printer according to the invention is characterized in that the box is arranged so that two separate, mutually isolating chambers are formed, one chamber accommodates the noise-producing mechanical means and is defined by box surfaces with no other opening than an inlet opening for the printable material and / or an outlet opening for the printed material, and that the second chamber contains the 25 mainly electrical and electronic heat emitting components and is bounded by box surfaces which may be formed with vent openings for heat dissipation.

Hensigtsmæssigt kan kassen være udformet i ét 30 stykke og indvendigt være opdelt i to kamre ved hjælp af en lydtæt skillevæg.Conveniently, the box may be formed in one 30 piece and internally divided into two chambers by means of a soundproof partition.

Med denne udformning vil de støjgivende dele af printeren være indesluttet i et hermetisk eller næsten hermetisk lukket kammer således, at den støj, der går 35 ud til omgivelserne, er stærkt dampet. Til gengæld kan det kammer, der rummer de elektriske eller elektroniskeWith this design, the noisy parts of the printer will be enclosed in a hermetically or nearly hermetically sealed chamber so that the noise exiting the environment is strongly vaporized. In contrast, the chamber that holds the electric or electronic can

Opfindelsen forklares nærmere herefter under 5 henvisning til to udførelseseksempler i fig. 1 og 2, der skematisk viser to printere, udformede i henhold til opfindelsen, og hvor man for overskueligheds skyld har udeladt de enkelte dele af printeren og kun vist kassen i tværsnitsplan.The invention will now be explained in more detail with reference to two exemplary embodiments of FIG. 1 and 2, schematically showing two printers, designed in accordance with the invention and for the sake of clarity the individual parts of the printer have been omitted and shown only the box in cross-sectional plane.

10 De to i fig. i og 2 viste printere omfatter en kasse l, som en indre skillevæg 4 deler op i to kamre 2 og 3. I de viste eksempler er skillevæggen 4 vandret, hvorved kassens indre deles op i et øvre kammer 2 og et nedre kammer 3. Det er dog klart, at 15 der kan være tale om en anden opstilling, alt efter printerens udformning, og at der ligeledes kan være tale om en skillevæg 4 af relativt indviklet form.10 The two of FIG. The printers shown in and 2 comprise a box 1 which divides an inner partition 4 into two chambers 2 and 3. In the examples shown, the partition 4 is horizontal, whereby the interior of the box is divided into an upper chamber 2 and a lower chamber 3. The however, it is clear that there may be a different arrangement, depending on the design of the printer, and that there may also be a partition 4 of a relatively intricate form.

Skillevæggen 4 har lydtæt forbindelse med kassen l's vægge og er udformet med et minimalt antal 20 åbninger, der navnlig for de elektriske forbindelser skaber adgang fra det ene kammer til det andet, hvilke åbninger i videst muligt omfang gøres lydtætte.The partition wall 4 has soundproof connection to the walls of the box 1 and is designed with a minimum number of 20 openings which, in particular for the electrical connections, provide access from one chamber to the other, which openings are made soundproof to the greatest extent possible.

Herved er der skabt mulighed for i det ene kammer, for eksempel det øvre kammer 2 at anbringe den 25 mekaniske del af printeren, der under driften udgør hovedstøjkilden. Den øverste del af kassen 1 har kun det minimale, absolut nødvendige antal åbninger til printerens funktion. Der kan eksempelvis være tale om udgangsåbningen 5 for de færdigprintede ark for den i 30 fig. 1 viste printer, hvor arkforrådet (ikke vist) befinder sig i kammeret 2, eller om arkindførings- og udtagningsåbninger 6, 5 for den i fig. 2 viste printer, i hvilket tilfælde arkforrådet 7 befinder sig uden for kassen 1.Thereby, it is possible to place in the one chamber, for example the upper chamber 2, the 25 mechanical part of the printer which during operation constitutes the main noise source. The upper part of the box 1 has only the minimum, absolutely necessary number of openings for the operation of the printer. For example, this may be the exit opening 5 of the finished printed sheets for the embodiment shown in FIG. 1, where the sheet stock (not shown) is in the chamber 2, or the sheet insertion and withdrawal openings 6, 5 for the embodiment shown in FIG. 2, in which case the sheet stock 7 is outside the box 1.

35 Det andet kammer, nemlig det nedre kammer 3 i den her viste udførelsesform, rummer de elektriske ogThe second chamber, namely the lower chamber 3 in the embodiment shown here, contains the electric and
