Detailed description of the invention

Below in conjunction with accompanying drawing shownschematically most preferred embodiment be described in further detail.

Printer of the present invention, can vertically, be attached to sinking on the guidance panel of a self-service fuel-servicing equipment.

See Fig. 1 and Fig. 2, printer embodiment of the present invention roughly comprises: upper casing 1, lower casing 2, printer main body 3, baffle plate 5, driving mechanism 7, position detecting switch 8 and a paper roll 9.

The lower end of this upper casing 1 is provided with pivot 11, and the middle part of this upper casing 1 is provided with outwardly and the nose 13 tilting to extend from top to bottom, and exit slot 131 is arranged on the lower end of this nose 13 with offering towards having a down dip.

This lower casing 2 has the cavity holding printer main body 3 and paper roll 9, and its both sides, lower end place is provided with pivot hole seat 21, may correspond to the pivot 11 connecting this upper casing 1, and upper casing 1 is pivotally attached on lower casing 2.Four sidewalls of this lower casing 2 are also provided with the seal groove 22 of upward opening, install an elastic seal ring to realize this upper casing 1 and the sealing of lower casing 2 in junction with correspondence.

This printer main body 3 comprises a microprocessor and by a printhead of this Microprocessor S3C44B0X and a paper advance mechanism etc.

The elastic seal cartridge 52 that this baffle plate 5 comprises a baffle body 51 and is installed in this baffle body 51.This baffle body 51 is provided with pivotal axis 511 at the first end place away from exit slot, and the second end place near exit slot is provided with a camshaft 512, and camshaft 512 is for having the cylinder in smooth cutting face.The pivotal axis 511 of this baffle plate 5 be articulated in be installed in these printer main body 3 paper delivery end both sides two installing racks 53 on.This pivotal axis 511 is also arranged with torsion spring 54.

This driving mechanism 7 comprises the cover plate 71 of a cam box; The body 72 of one cam box; One motor 73, its rotating shaft is arranged with a worm screw 731; One worm gear 74, it has the gear shaft of docking; And a worm gear 74, it has the gear hole of docking.Cam 75 overlaps with the camshaft 512 on this baffle plate 5, and namely both outlines abut.Thus when motor 73 controlled rotation, the pivotal axis 511 of the second end of this baffle body 51 around the first end place of this baffle body 51 can be driven to rotate.

See 3a, 3b, 3c and 3d, this baffle plate 5 is driven and is opened this exit slot, when printer needs to print, when paper is sent, microprocessor in this printer main body 3 provides control signal and controls this motor 73 action, and motor 73 drives this baffle body 51 action via worm screw 731, worm gear 74 and cam 75, and at this moment the galianconism of cam 75 supports camshaft 512, until this baffle body 51 is in minimum point, the angle w between itself and horizontal line is about 13 degree.At this moment position detecting switch 8 provides the microprocessor that an enable possition signal notifies in this printer main body 3, and it can provide control signal in time according to this signal and control this motor 73 and stop action.

See 4a, 4b, 4c and 4d, this baffle plate 5 is driven and is closed this exit slot, when printer complete print paper is sent after, microprocessor in this printer main body 3 provides control signal and controls this motor 73 action, motor 73 is via worm screw 731, worm gear 74 and cam 75 drive this baffle body 51 action, at this moment the galianconism of cam 75 supports camshaft 512, until this baffle body 51 is at the highest notch, angle w between itself and horizontal line is about 22 degree, that is, second end of this baffle body 51 driven by this driving mechanism and the angular range rotated around the first end of this baffle body 51 within 10 degree.At this moment position detecting switch 8 provides the microprocessor that a closed position signal notifies in this printer main body 3, and it can provide control signal in time according to this signal and control this motor 73 and stop action.

It should be noted that, position detecting switch 8 both can select a two-position detection type, and Liang Ge unit also can be adopted to put detection type.Or only need detect one of them position, another position can by the program run in microprocessor according to the coaptation of the rotating speed of motor and transmission mechanism out.

Compared with prior art, printer of the present invention, by arranging baffle plate 5 and a driving mechanism 7 of rotatably On/Off exit slot, can realize only driving this baffle plate 5 to open this exit slot when print state, and drive this baffle plate 5 to close this exit slot when non-print state, thus the sealing of exit slot can be realized well, there is the ability of stronger anti-aqueous vapor, oil gas and dust.

Above, be only the preferred embodiment of the present invention, be intended to further illustrate the present invention, but not it is limited.All simple replacements carried out according to the content disclosed in above-mentioned word and accompanying drawing, all at the row of the rights protection scope of this patent.
