Definitions
- the invention relates to office machines comprising a printer. associated with a paper roll.
- a desktop machine like this, we can for example quote a fax machine or a portable terminal of payment.
- the paper roll is received in a housing closed by a cover articulated on the machine chassis.
- a cover articulated on the machine chassis When the paper runs out, we open the hood and put a refill.
- the motor and the control kinematics of a paper friction roller in front of the print head form a single unit.
- the installation of paper is difficult because it is necessary to introduce the primer end into a slot for access to the drive roller and head. So you have to have both hands and so put the machine down if it is a payment terminal.
- part of the elements of the kinematic chain is integral with the cover and, being thus mobile, it thus provides better access to place the refill of paper in its housing and to make cooperate the bait with the head.
- the gear cogwheels between the fixed part and the mobile part of the chain kinematics use these.
- the drive train is not fully protected and may be damaged during handling or by the penetration of polluting particles.
- Document US-A-5,791,796 discloses an office machine including a roll paper printer in a frame, with a paper roll housing, and a housing and cover closure. Roller drive means mounted on the cover.
- the present application therefore aims to further improve and simplify the machine of the type defined above.
- the invention relates to a machine according to claim 1.
- all the mobile elements, for driving the paper form a block and are therefore not very sensitive to external aggressions.
- the kinematics is completely removed from the print head and thus frees access, so that the primer of the paper can easily be engaged at head level.
- the payment terminal partially shown in Figure 1 includes a print head 2, mounted in a chassis 1, on a spring 21, chassis 1 which receives a cover 3 for closing a housing 10 of a roll 12 of printing paper.
- the cover 3 is mounted mobile on the chassis 1 and, in this example, pivots on this around a theoretical axis 31, the mechanical connection corresponding being constituted, at each end of the axis 31, by interlocking of male and female cylindrical elements.
- the cover 3 could be entirely detachable from the chassis 1, like a refill or removable cartridge comprising consumable paper, and fix it with a snap device with possibly guide rails to facilitate the installation of the cover.
- the cover 3 is integral with a kinematics for driving the paper 12 in front of the head 2, of which only one friction drive roller 4, with pressing against the head 2, is shown in Figures 1 and 2.
- the kinematics above mounted on the cover 3 is moved away from head 1 and frees access to housing 10 for there put a roll of 12 refill paper. Head 2 is then accessible, and just pull the primer end of the paper roll 12 and the place in front of head 2, against which it is then pressed by the drive roller 4 when the cover 3 is folded down.
- the terminal is therefore in two mobile parts, one relative to each other and arranged to house the paper roll 12 and allow its replacement.
- the cover 3 is in fact an auxiliary chassis carrying the kinematic chain 4, 5, 6 (fig. 3) and which, preferably as here, forms a sealed wall closing the chassis 1.
- FIG. 2 illustrates the functional position of the drive roller 4, forming a counter-support with the head 2 to press and drive by rub the paper 12.
- Figure 3 shows in more detail the drive kinematics of the paper 12, carried by the cover 3. It comprises a stepping motor 6 controlling a chain of gears 5, the last of which rotation of the drive roller 4.
- the roller 12 does not rest on the bottom of the housing 10 but is supported by a mandrel 11 rotatably mounted on two ends bearings carried by two opposite lateral cheeks of the cover 3, only one of the bearings, 33, being shown.
- the cover 3 includes a skirt 32 opposite, relative to the axis 31, to the rest of the cover 3 which carries the chain kinematics 4, 5, 6.
- the skirt 32 protrudes towards the inside of the chassis 1 and occupies a position located at the limit of the housing 10, under the paper roll 12, and serves as a support or guide facilitating the positioning of the roller 12.
- cover 3 closed position the skirt 32 is folded against the internal face of the chassis 1 and thus seals the chassis 1 in this zone.
- the edge 34 of the cover 3 parallel here to the axis 31 and located near the drive roller 4 forms a stop in support on an opposite abutment edge 14 of the chassis 1, which regulates the relative positions of the head 2 and the drive roller 4. This adjusts so head 2 - roller 4 cooperation at the desired force or pressure to drive by friction, without sliding and without excessive stress, the paper 12 which is pressed between them.
- the stop of the opposite edges 14 and 34 takes place only at the axially opposite ends of the edges 14 and 34, that is to say that, at each end, at least one of the edges 14 and 34 has a protrusion, not drawn, forming a spacer. Both above protrusions are axially spaced apart by a distance slightly larger than the width of the paper 12. As a result, the areas opposite edges 14 and 34 are, in the closed position, in sight and at a short distance and delimit a paper exhaust slot 12, downstream of the print head 2.
- an elastic damping element can be provided such as an elastic stop tongue or skirt resisting elastically closing the cover 3. It could be a skirt secured to the chassis 1 and on which the cover 3 or any element that it carries would come up against.
- the elastic skirt is on the contrary secured to the cover 3 and, precisely, is constituted by the sealing skirt 32; who thus has two functions.
- the elastic deformation of the skirt 32 which occurs during the complete closing of cover 3 absorbs excess kinematic energy folding the cover 3 and thus limits the possible impact of the cover 3 on the chassis 1.
- a disengageable mechanism for holding in position closed cover 3 is then provided, for example a ratchet device. The releasing the pawl opens automatically, at least partially, the cover 3 thanks to the energy stored in the skirt 32.
- the protection of the kinematic chain 4, 5, 6 is also ensured here by a casing 7, mounted on the cover 3 and represented only by dashed mounting lines thereon, casing 7 which surrounds watertight the gears 5 and even here the motor 6.
- the roller 4, or at least one sector of contact with the head 2, is by against accessible.
