Description

The mini-printer that on static interface, moves

Affiliated field:

The utility model belongs to electronic information process field, particularly mobile computing and printing technique.

Background technology:

The area of present output printing device all is greater than output medium, carries extremely inconvenience when mobile office.Along with calculation element is more and more littler, wireless communication bandwidth is more and more wideer, and calculating and communication cost are more and more cheap, and the demand of pocket-type printer is also just urgent more.Particularly the hand-held computing equipment is universal, and information output is indispensable during mobile office.Print if can solve the information of palm computing equipment, also can solve the too little problem of palm computing equipment information display window simultaneously.

Goal of the invention:

The objective of the invention is by a kind of radio tracking servo-control system and location technology, be implemented in output on the quiescent atmosphere face, according to the instruction of calculation element, by hand-held device self mobile print output picture and text with ink-jet or other printing technique.The technical scheme of invention:

Implementation of the present utility model is, utilizes wireless location technology and servo control technique, drives mini-printer and moves at static interface, thereby make the printer microminiaturization, and the position deviation that produces when eliminating printer simultaneously and moving improves print quality.

Each ingredient and the annexation of this mini-printer comprise: referring to accompanying drawing 1

1.A be a calculation element, and have the wired or wireless communication ability, it is connected (1) by wave point with B;

2.B comprise wireless communication interface, compositions such as instruction decode mouth and buffer memory, its task is

A) instruction that A is transmitted is deciphered.

B) A is given x, y coordinate are delivered to H after deciphering.

C) whether decision is printed or is lifted the pen signal of starting to write and send I on x, y coordinate position.

D) carry out (2) synchronously with C.

3.C control Driver Circuit, its main task are to provide (x of given x, y and F actual measurement, the difference of y) Δ x, Δ y according to H to regulate control.Make error minimize.Drive D (4), E (5) according to regulating control signal.

4.D, E is micromachine, driving rolls moves to appointed positions when being responsible for printing.

5.F, G detects that printhead moves the coordinate that place x, y are ordered in known x, y coordinate range.F is and is fixed on the locational pulse signal generator G of x in the known coordinate, y cooperative (10).The following (see figure 3) of its principle:

A) Gl, Fl are respectively that infrared signal transmits and receives head, and the velocity of propagation of known light is 300,000

Kilometer/s is so receive emission infrared ray its time delay of relative acoustic velocity V=344 rice/S

Ignore.Gs1 and Gs2 are the ultrasonic generators of G part, and they are to be fixed on

Know in the coordinate, and fixing distance is arranged.Fs is the ultrasonic sensing device of F part, and it moves

In the known coordinate scope on x, the y point.

B) when Fl emission infrared signal, received by Gl, the Fj counter picks up counting Gs1 simultaneously

Also send ultrasound wave simultaneously.When ultrasound wave (Gs1) arrived Fs, the Fj timing stopped.Super

The transit time of sound wave from Gs1 to Fs is t1.Fl sends second infrared signal this moment,

In like manner can obtain another transit time of t2.At this moment, we are known: Gs1 and Gs2 distance

Be fixed constant C.S1=Vt1, S2=Vt2, V=344 rice/s.The x of Fs, y so

Coordinate Calculation just can obtain.

C) acquisition of next coordinate points repeats the said process (see figure 3).

D) or also can F be ultrasonic transmitter, the G stiff end be equipped with Gs1 and Gs2 (reception sound

The inductor of ripple).Principle of work is as follows: Fl sends infrared signal, and Gl opens after receiving simultaneously

Moving Gj1 and Gj2 carries out timing and Fs sends ultrasonic signal.When Gs1 or Gs2 reception

Behind ultrasonic signal, stop the timing of Gj1 or Gj2, at this moment obtain hyperacousticly to get over

Time t1 and t2.Obtain x, the y coordinate that Fs is ordered with above-mentioned scheme is the same.(see figure 4)

6.I function receive that F (7) actual measurement coordinate points x, y receive simultaneously that B (8) sends that x, y dot printing control command or x, y order lift the control command of starting to write.Two signals carry out the ink marks that has or not that logic control determines that jointly this x, y order.

7.J for the topworks of printhead or pen controls (9) by I.An electromagnet is arranged simultaneously by its clutch of I control and move up and down on the J.

8.H the given x of effect calculating place, y point coordinate and actual measurement (6) x, difference DELTA x, the Δ y of y point coordinate.Produce when this error is walking, Δ x, Δ y are sent into C, proofread and correct (11).

9.K, L is driving wheel (or mobile bar), walking (or moves wheel by the weight of printer own on paper

9.K, L is driving wheel (or mobile bar), walking makes wheel (or mobile bar) and paper produce friction force by the weight of printer own on paper.When walking on vertical blank, blank must be an iron, and wheel (or mobile bar) is magnetic simultaneously.

When writing on blank, the blank vertical ground is put, and roller (K L) has magnetic.Additional electromagnet in printhead (J) unit or iron, remove to adsorb a blackboard eraser that has iron or electromagnet, and move up and down perpendicular to blank by printhead control module (I) control electromagnet, carry out the plane by servo-drive system control printhead (J) unit and move and wipe the ink marks that to wipe on the blank.

Referring to accompanying drawing 2, in addition locating device (G) part can and calculation element (A) be one but also separable, when released state is used, locating device (G) and available wired or wireless connection of calculation element (A).Beneficial effect:

The utility model can solve the information of palm computing equipment and print problem, has also solved the too little problem of palm computing equipment information display window simultaneously.
