Description
Technical field
The present invention relates to the mobile printer of a kind of printer, more particularly to four-wheel.
Background technology
At present, there is the ink-jet printer structure of two kinds of routines.A kind of is the scan-type structure in domestic and commercial kitchen area, paper
Open and print area is entered and left under power traction, printhead is arranged on the track in sheet movement direction along track
Make reciprocating scanning and printing.This mode, track length limits the width of printable paper, in order to accurate tracking prints position
Put, paper and printhead are respectively using the motor for possessing precise positioning ability（Such as motor）Drive, also have using grating,
The position code devices such as magnetic grid are detected to the feeding distance of paper.
Another kind is referred to as one way print structure, is commonly used in Industrial Printing field.The printhead of big width is used, or
Multiple printheads are grouped together into into the printhead cluster of big width, paper below printhead, is beaten under power traction
Print head ink-jet output completes to print.Printable maximum paper width is limited by printing head width and structure design.Print position
Determined by the rotational angle of motor, or the feeding distance of paper is detected come really according to position coders such as grating, magnetic grids
It is fixed.
Motor is a kind of controlled motor that electric impulse signal can be converted into angular displacement output, by mechanically operated
Conversion, angular displacement is easily transformed into the displacement in rectilinear direction, therefore motor can be used for accurate paper feed distance
Control.
The printer of traditional structure, due to the restriction of physical dimension, it is impossible to realize large-sized Free Printing；And do not have
Standby portable performance.These mobile offices for all limiting people need and flexibly use the demand of printer.
The content of the invention
To solve the problems, such as that prior art printer can not realize Free Printing, not have portability, there is provided four-wheel of the present invention
Mobile printer, this printing function is moved freely on the print medium, possesses the ability for printing large scale picture and text；This shifting
The overall dimensions of dynamic formula printer can be made to compact, be convenient for carrying, and be conducive to mobile office.
For achieving the above object, the present invention is employed the following technical solutions：
A kind of four-wheel mobile printer, including a frame, are provided with power supply, motor, mobile device, ink-jet and beat in frame
Print head and central processing unit, central processing unit includes mobile control unit and print control unit；Mobile device is according to mobile control
The instruction that unit processed sends, makes frame move integrally appropriate position, and ink jet-print head sends according to print control unit
Instruction carries out inkjet printing；Described mobile device includes the road wheel group of two groups and motor connection, and every group of road wheel includes two
Road wheel, this two road wheels with group are arranged in same rotary shaft, and the pivot center of two groups of road wheel groups mutually hangs down
Directly.
Above-mentioned four-wheel mobile printer, central processing unit memory storage organic frame mobile route and printhead ink-jet position
Put；After machine frame movement is found to default position, with print control unit communication, the instruction of inkjet printing is sent.
Above-mentioned four-wheel mobile printer, the periphery of described road wheel is provided with several auxiliary wheels, auxiliary wheel
Pivot center is vertical with road wheel.
Above-mentioned four-wheel mobile printer, the wheel face of described auxiliary wheel is circular arc, and auxiliary wheel is installed by bearing
On road wheel periphery.
Above-mentioned four-wheel mobile printer, is provided with the rotating shaft position coder.
Above-mentioned four-wheel mobile printer, described motor is motor.
The movement on mobile printer two-dimensional direction on paper is realized by two groups of orthogonal road wheels, i.e., in fact
Existing mobile printer carries out the movement of orthogonal X, Y-direction on paper, each shifting for being responsible for a direction of per group of two road wheel
It is dynamic.When one group of road wheel carries out rotating so that mobile printer is moved along this direction in one direction, another group
Road wheel stops operating.The movement of free scan-type is so achieved that, printer is made departing from fixed frame, can be more
Free Printing is carried out on paper in large scale.
Using motor, the motion direction of printer can be accurately controlled so that precise Printing content is possibly realized.
Precise Printing can also be controlled by the positional information of position coder acquisition printer.
Auxiliary wheel plays a part of to reduce frictional force.When the road wheel in a direction is rotated, and the action in another direction
Wheel stops operating, at this moment, because four road wheels are all contacted with paper, the pivot center and printer of the road wheel of other direction
Moving direction it is vertical parallel with the pivot center of the road wheel for driving printer movement so that the road wheel of other direction leads to
Cross auxiliary wheel to contact with paper, this road wheel reduces the frictional force with paper by auxiliary wheel.
On the end to end i.e. composition this action wheel rotational plane of rotary shaft of all auxiliary wheels on one road wheel one
Individual regular polygon；No matter how road wheel or auxiliary wheel move, and the wheel facial contour outside of any time all auxiliary wheels is in action
Projection on the rotational plane of wheel is all located on same circumference, and this circumference constitutes the excircle of road wheel, four action
The excircle of wheel simultaneously with print media plane contact.
