The specific embodiment

Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.

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

Referring to Fig. 1 and Fig. 2, printer embodiment of the present invention roughly comprises: a upper casing 1, one lower casing 2, one printer main bodies 3, one baffle plate 5, one driving mechanisms, 7, one position detecting switch 8 and paper rolls 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 an outwards nose 13 outstanding and that tilt to extend from top to bottom, and exit slot 131 is to be arranged on the lower end of this nose 13 towards having a down dip with offering.

This lower casing 2 has the cavity that holds printer main body 3 and paper roll 9, and its place, both sides, lower end is provided with pivot hole seat 21, can corresponding connect the pivot 11 of this upper casing 1, and upper casing 1 is pivotally attached on the lower casing 2.Also be provided with the seal groove 22 of upward opening on four sidewalls of this lower casing 2, install an elastic seal ring to realize this upper casing 1 and the sealing of lower casing 2 in the junction with correspondence.

This printer main body 3 comprises a microprocessor and a printhead that is subjected to this microprocessor control and a paper advance mechanism etc.

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

This driving mechanism 7 comprises the cover plate 71 of a cam box; The body 72 of one cam box; One motor 73 is arranged with a worm screw 731 in its rotating shaft; One worm gear 74, it has the gear shaft of docking usefulness; And a worm gear 74, it has the gear hole of docking usefulness.Camshaft 512 overlap joint, namely both outline butts on cam 75 and this baffle plate 5.Thereby when motor 73 controlled rotation, can drive the second end of this baffle body 51 around pivotal axis 511 rotations at the first end place of this baffle body 51.

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

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

Need to prove that position detecting switch 8 both can have been selected a two-position detection type, also can adopt two units to put the detection type.Perhaps, only need to detect one of them position, another position can be by the program of moving in the 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 rotatably a baffle plate 5 and a driving mechanism 7 of On/Off exit slot are set, can realize only in print state, driving this baffle plate 5 and open this exit slot, close this exit slot and in non-print state, drive this baffle plate 5, thereby can realize well the sealing of exit slot, have the ability of stronger anti-aqueous vapor, oil gas and dust.

More than, only be the present invention's preferred embodiment, be intended to further specify the present invention, but not it is limited.All simple replacements of carrying out according to above-mentioned literal and the disclosed content of accompanying drawing are all at the row of the rights protection scope of this patent.
