Specific embodiment
The present invention is described in further detail below by specific embodiment combination accompanying drawing.
Fig. 1-Fig. 3 is referred to, one embodiment of the invention provides a kind of paper delivery mechanism 1, and the paper delivery mechanism 1 is arranged at impression block
The outside of block 3, for the paper transmission between the paper delivery mouth 31 and panel exit slot 2 of print module 3, sets in the print module 3
It is equipped with control centre（It is not shown）For the control between each module in whole printer.The paper delivery mechanism 1 is included for installing
The frame of each parts of fixation（Non- label）, transmission channel 18, the first roller group 11, the second roller group 14, first sensor
131st, second sensor 132 and driving-chain（Non- label）.The one end of transmission channel 18 connects with the paper delivery mouth 31 of print module 3,
The other end is connected to panel exit slot 2.The roller of first roller group 11 is respectively placed in the both sides of transmission channel 18, and roller is set.
The first sensor 131 is placed between the first roller group 11 and paper delivery mouth 31, and the second sensor 132 is placed in the second roller group 14
Enter the side in paper direction, the first sensor 131 and second sensor 132 are respectively used to detect the transmission channel of corresponding position
Whether 18 have paper to pass through, and relevant information is fed back to the control centre of print module 3.The driving-chain is driven by motor, can
For the first roller group 11, the second roller group 14 provide operating power.
First roller group 11 includes being arranged at roller the fixed idler whell 113 and action roller 112 of the both sides of transmission channel 18,
And controlled center instruction can make action roller 112 lift and depart from fixed idler whell 113 the roller lifting dress set to roller
Put 12.
Fig. 4 is please referred to, the roller lifting apparatus 12 include motion bar 121 and extension spring 122.The driving-chain is received including one
Motor-driven power transmission shaft 171.The motion bar 121 is substantially vertical with power transmission shaft 171 to intersect setting, and the action roller 112 is connected
In the one end of motion bar 121, the other end of motion bar 121 has to be marked with the mating holes of the phase frictional fit of power transmission shaft 171
Number）, interference fits are used between the mating holes and power transmission shaft 171.The extension spring 122 is connected to the one end of motion bar 121 for providing
The restoring force for making the action roller 112 on the motion bar 121 with the holding of fixed idler whell 113 separate.When power transmission shaft 171 rotates,
Dynamic friction can be produced between power transmission shaft 171 and motion bar 121, the frictional force can make motion bar 121 overcome the pulling force of extension spring 122 to make
Action roller 112 is obtained to be kept to roller fricting movement with fixed idler whell 113, to drive paper to be pushed forward in transmission channel 18,
When driving-chain shuts down, the power transmission shaft 171 is rotated, and the restoring force by extension spring 122 is acted on, can be by the lifting of motion bar 121
Rise, action roller 112 is departed from fixed idler whell 113 and roller is set, so that into the paper in transmission channel 18 at this
Lose the power for pushing forward in place.
One end of the action roller 112 is provided with the first gear 174 with the coaxial transmission of action roller 112, the driving-chain
Also include being fixed on power transmission shaft 171 second gear 172 with the coaxial transmission of power transmission shaft 171, and be placed in the second gear
Idler gear 173 between 172 and first gear 174, by the transmission of driving-chain, drives first gear 174 and action roller
112 are mutually driven.
Second roller group 14 includes about two rollers that the both sides of transmission channel 18 are arranged to roller, and second roller
Group 14 is disposed adjacent at panel exit slot 2.Two rollers include an active roller 141 and a return idler 142, and this is actively rolled
Wheel 141 passes through corresponding dynamical element（It is not shown）It is driven, when second sensor 132 has detected paper to be reached, should
To control centre, the control centre is that the corresponding dynamical element of instruction drives to the information transmission that second sensor 132 will be detected
The active roller 141 is mutually driven, and will be sent to the paper tape at this and goes out panel exit slot 2.
During printing, print command is input into, the paper printed when print module 3 out and enters into biography through paper delivery mouth 31
After in defeated passage 18, the first sensor 131 has sensed that paper passes through, and information can be uploaded into control centre, control centre
Analysis can be made to judge, if print command input is one side printing, the driving-chain starts to drive power transmission shaft 171 to rotate；One
Aspect, the relative motion bar 121 of power transmission shaft 171 starts rotation, and the frictional force between the power transmission shaft 171 and motion bar 121 can make
The motion bar 121 produces the motion of rotating down pressing, and overcomes the pulling force of extension spring 122, until being connect to roller with fixed idler whell 113
Touch；On the other hand, the driving-chain drives idler gear 173 and finally drives by the second gear 172 set on power transmission shaft 171
First gear 174 and the coaxial rotating of action roller 112 so that action roller 112 and fixed idler whell 113 to roller operating will can enter
Enter the paper in transmission channel 18 further to push forward.When paper is sent to the second roller group 14, the second sensor 132
Paper is detected to pass through, the information can be uploaded to control centre, the control centre can order-driven second roller group 14
The associated power element of transmission is started working, and paper is sent into panel exit slot 2 after second roller group 14 is driven, is completed
Printing.
If print command input is duplex printing, when the paper completes the first face to be printed, it runs to the first biography
When at sensor 131, control centre can instruct driving-chain to shut down after receiving the detection information of first sensor 131, the activity
Roller 112 is lifted and departed from fixed idler whell 113 and roller is set by the pulling force effect of extension spring 122, and first roller group 11 is by nothing
Method provides the power for advancing for paper, and the paper stops transmitting and being built and the roller in print module 3（It is not shown）Clamping
Firmly, slightly stop in a moment, the paper can be automatically retracted by print module 3, and carry out the second face printing.When the paper completes the second face
After printing, after the paper enters paper delivery mechanism from paper delivery mouth 31 again, the paper delivery mechanism can perform the step identical with one side printing,
Paper is normally expelled to panel exit slot 2.
In alternate embodiments, the extension spring 122 can also be the reply element of the other forms of shell fragment or jump ring etc.
The roller lifting apparatus 12 can also other forms controlled center dependent instruction control after action roller 112 can be lifted
Rise the lifting mechanism or device that are set to roller for making disengaging and fixed idler whell 113.
The paper delivery mechanism 1 of the support duplex printing that the present invention is provided can aid in print module 3 to realize duplex printing, device
Simple structure, in modularization, it is easy to install.
Above content is to combine specific embodiment further description made for the present invention, it is impossible to assert this hair
Bright specific implementation is confined to these explanations.For general technical staff of the technical field of the invention, do not taking off
On the premise of present inventive concept, some simple deduction or replace can also be made.
