The specific embodiment

Do further to detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.

The printer of the utility model, 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, the printer embodiment of the utility model 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 a nose 13 outwards 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 receives this microprocessor control and a paper advance mechanism etc.

This baffle plate 5 comprises a baffle body 51 and is installed in the elastic seal cartridge 52 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 butt joint usefulness; And a worm gear 74, it has the gear hole of butt joint usefulness.Camshaft 512 overlap joint, just both outline butts on cam 75 and this baffle plate 5.Thereby when motor 73 controlled rotation, can drive of pivotal axis 511 rotations of second end of this baffle body 51 around 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 print; When paper is seen off; Microprocessor in this printer main body 3 provides these motor 73 actions of control signal control, 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 replaced camshaft 512; Be in minimum point until this baffle body 51, 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 the microprocessor in this printer main body 3, and it can provide this motor 73 of control signal control in time according to this signal and stop action.

Referring to 4a, 4b, 4c and 4d; This baffle plate 5 is driven and is closed this exit slot, and after paper was seen in printer completion printing off, the microprocessor in this printer main body 3 provided this motor 73 actions of control signal control; Motor 73 drives this baffle body 51 actions via worm screw 731, worm gear 74 and cam 75; At this moment the galianconism of cam 75 is replaced camshaft 512, is at the highest notch until this baffle body 51, and the angle w between itself and the horizontal line is about 22 degree; That is to say, second end of this baffle body 51 by this drive mechanism around the angular range of first end of this baffle body 51 rotation in 10 degree.At this moment position detecting switch 8 provides a closed position signal and notifies the microprocessor in this printer main body 3, and it can provide this motor 73 of control signal control in time according to this signal and stop action.

Need to prove that position detecting switch 8 both can have been selected a two-position detection type for use, also can adopt two units to put the detection type.Perhaps, only needing to detect one of them position, can be come out according to the coaptation of rotating speed of motor and transmission mechanism by the program of moving in the microprocessor in another position.

Compared with prior art; The printer of the utility model; Through 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 the sealing of exit slot well, have the ability of stronger anti-aqueous vapor, oil gas and dust.

More than, be merely the preferred embodiment of the utility model, be intended to further specify the utility model, but not it is limited.All simple substitution 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.
