In scanner head inside a lot of parts are housed, following explanation: a part at least wherein is to start indirectly by trigger 28 across-the-line startings or by microprocessor 30, one of parts are to start light source, just produce the semiconductor laser diode 32 or the light emitting diode of incident beam with trigger 28 startings, if laser diode, light beam is dispersed very much, the footpath is upwards asymmetric, the cross section is oval, about 7000 dusts of wavelength, laser diode 32 can be launched continuous wave, also can be pulsating wave, laser diode 32 must have low-voltage (after direct current 12V), can be the battery that is contained in the handle 12, also can be to be contained in detachable rechargeable battery set in the scanner head, or external power source insert in the scanner head with lead.

In the scanner head, the optical devices that relative laser diode 32 adjustable positions are arranged, comprise that demifacet is coated with the catoptron 37 and the optical module 38 of silver, incoming laser beam is revised, and make incident beam incide reference field along the 1st light path, and reference field is located at the place ahead of antetheca 16, the outside of scanner head, and this reference field is vertical with the direction of propagation of laser beam.The bar-code marks that reads be placed on the reference field or with scanner head homonymy or its opposite side, generally speaking, be placed within the incident beam field depth of optics correction, field depth is exactly the operation distance that can read mark, incident beam is reflected to a lot of directions by each mark, by that part of towards scanner head reflection of mark, be called returning part here.

Laser beam arrives the planar section of scanning reflection mirror 40 by optical module, by scanning reflection mirror 40 to front-reflection, by the optical transmission window 44 that is provided with on the antetheca 16, along the mark of direction directive shown in the arrow 42.

Scanning reflection mirror 40 is contained in scanning with on the driver part, and the turntable driving parts preferably select for use the high-velocity scanning of No. 4387397 record of United States Patent (USP) with motor 46, in this application, only point out, have fixedly adorned a Support bracket on the output shaft of motor 46.

Scanning reflection mirror is installed on the above-mentioned Support bracket, and with per second speed for several times, is driven alternately along circular arc, and circular arc can be the length of the following arbitrary circular arc correspondence of 360 degree.

Scanning reflection mirror 40 and output shaft are shaken with the speed of per second 20～40 times, and make the laser beam that is mapped on the catoptron 40 with 32 angular distance (observing) scanning repeatedly from reference field.

During scanning, because the each several part reflection characteristic difference of bar-code marks, thereby intensity is different, the laser beam of returning (shown in the arrow 48), concave part by catoptron 40 compiles, and arrives on detection part such as the photodetector 50 by optical module 38 and half-reflecting mirror 37 then.Photodetector 50 (preferably photodiode) detects along the laser of the various intensity of collecting in the visual field that sweep trace launches, and produces the analog electrical signal of reflection light intensity.

Be contained in the analog electrical signal that 52 pairs of photodiodes of signal place device on the circuit substrate 54 50 produce in the scanner head and handle, make it become digitized vision signal.The data of this mark to be obtained representing by digitized vision signal, the signal processing circuit of United States Patent (USP) the 4251798th record can be adopted for this reason.In addition, the driving circuit of motor 46, the optical registration control device that laser diode 32 is used when the laser that the generation people sees far from eye also are housed in scanner head, be the laser diode power supply, and the electric pressure converter that the input voltage battery is suitably adjusted.

Decoding/control device 56 also is housed on circuit substrate 54, in order to digitized video is become the digitizing decoded signal, the PROM that utilizes the algorithm in the software control procedures in the microprocessor 30 from the digitizing decoded signal can obtain representing the data, decoding/control device 56 of mark, to have to include program and the RAM of temporal data, decoding/control device 56 determines with microprocessor 30 whether the decoding of mark has been finished, and stopping reading of mark in view of the above, reading by pushing trigger 28 of bar-code marks begins.But decoding/control device 56 is in order to starting unit in the gated sweep probe, promptly by the starting of laser diode 32, photodiode 50, motor 46 and other all electronic circuits of trigger starting.Also have control circuit in addition, give pilot bulb 58 control signal and make it luminous, make the hummer sounding, the operator is learnt read to be over.

Decoded signal or by the lead in the cable perhaps passes at a distance principal computer by radiowave from scanner head by means of antenna 36.Computing machine 60 (microcomputer in the shop is good) has large database, the storage decoded signal, the information relevant with decoded signal is provided, as, in the present invention, principal computer can be with the corresponding retail price decoding of information of recognition value, upgrades then or him is provided usefulness, and principal computer can couple together with fixed terminals such as portable terminal or the automatic recorders of the amount of money.

Also be provided with key 59 at scanner head, so just can be easily with mark or (with) commodity data that has a mark imports into.In addition, on the upper wall 20 of scanner head, a display 64 is housed also near the keyboard 59, so just can illustrate easily with mark and (or) have the relevant information of commodity of mark.

As mentioned above, each commodity of bar-code marks have been printed, method as shown in Figure 2, with portable scanner head 10 scanning marks, just can discern, but information such as price are come out by the database real-time inspection of principal computer 60, and canned data can lean on the keyboard input to carry out regular update, raises the price or price reduction with reflection.When being carried to on-the-spot the use, can be contained in database in the chest, this chest can be held in another on hand or hang on operator's the waistband or carry on the arm piggyback.

Under the situation that the information of database storing is updated, in order to reflect updated information, the data that machinery or people can be able to be read are printed on the new mark.Printing can be carried out with printer 62, printer can be contained on the portable scanner head 10 (see figure 1) or a hand is held, perhaps the operator is worn at (see figure 2) on one's body, perhaps is placed on the checkout station, perhaps as described below being contained on other device such as scale or the automatic recorder of the amount of money.Printer has heat typewriting 61, graphic sign can be printed on the mark paper roll with the hot print method, paper roll is supported on the bearing, the front end of printing that respectively is marked at scanner head 10 is torn, be pressed onto on the edge of a knife 65 and be cut off, directly be attached on the commodity or be attached near the former mark, perhaps overlapping subsides are preferably in new mark inner face and coat pressure sensitive adhesive thereon.

Below Fig. 3 is illustrated, in workstation1 00,, has base station 104, one ends to connect adjustable swan-neck jib 108 that scanner head 102 other ends connect base station 104 on table top or the same supporting surface 106 at scanner head 102.Big portion or whole parts all can be contained in the above-mentioned workstation1 00 in Fig. 1 portable scanner head 10.At this moment, trigger 28 can omit.Arm 108 is a hollow; Can be by the electric signal of cable transmission scanner head 102 inner parts.Arm 108 is semirigid structures, is made by metal material, so that make it also can remain on the position of hope then to selected direction alternating bending with hand.Mat bend arm 108, scanner head 102 can regulated at will make it aim at bar-code marks, and bar-code marks is that the scope of operations that are placed on outside the scanner head 102 are near the reference field.The scope of operation is that reference field is preferably on the table top 106 or in its high slightly position, perhaps in stylobate 104 planes or high slightly position.

Cable 110 couples together workstation1 00 and terminal 112 (as the amount of money self-recorder of POS system).Display 114 is housed in the terminal 112, is used for display message and gives the operator, comprising the data of bar-code marks in the scanning; Keyboard 116 also is housed, so that operator's input information comprises the data of describing bar-code marks; Also be provided with the cash drawer 118 of keeping money; Also have paper tape 120, in order to recorded information and to bought scanned have bar-code marks client demonstration is provided; Be contained in base station 104 in addition or the charger 122 to battery charge of the scanner head 102 of packing into; Decoding module 124 (this example, decoding module be not at base station 104, in arm 108 or the scanner head 10); The database 126 of principal computer also is housed.Connector 128 can remove the data conversion storage of storage to other databases.

Armamentarium shown in Figure 3 is called intelligent terminal, by means of more than 108 ingenious location of freedom of motion of arm, can make the laser beam (shown in the arrow 130) of ejaculation can aim at bar-code marks well, and, also can collect well by mark and return next reflected light.

The laser scanning head 100 of Fig. 3 is that workstation is the retroreflection formula, and the laser beam of coming out and the visual field of photodetector all will be through overscanning.Change form and be also included within that this is understandable in the scope of the invention.For example, the laser beam of coming out certain window by scanner head sweeps away also passable facing to bar-code marks, yet the laser that returns in the visual field through scanning can not collected by other windows of scanner head yet with ing.Or the laser beam of coming out do not scan facing to mark, but Returning beam will be through scanning in the visual field in.

Printer 62 can be contained in the scanner head.As shown in Figure 3, printer 62 is contained in the handle shape extension of scanner head, originally is contained in can move on to any parts in the shank in base station 104 or the terminal 112.

Utilization is contained in the scale on the base station 104, and the weight, particularly price and the weight that can weighing be placed on the commodity on the weighing platform are related, preferably is placed on the weighing platform as commodity such as meat or fishes and weighs.It is fish, meat etc. that scanner head 102 utilizes the bar code label of printing to discern, and price is calculated by system microcomputer.Mark that printer 62 is got with mechanical-readable on new mark and alphanumeric form print trade name, price and unit price.The new mark of printing is attached on the former indication of goods.Above-mentioned whole operations can be at the checkout station away from the supermarket, as carrying out in the independent place of selling meat, fish.Client just can know the real price of commodity before coming checkout station like this.At checkout station, as mentioned above, the salesman is as long as the electricity consumption optical scanner is swept new mark, the purchase of commodity, accounting procedure just soon how (with reference to Fig. 9), below just be called " no pin printing " embodiment among Fig. 4 and be illustrated, in this embodiment, most of parts in Fig. 1 portable scanner head or whole parts can be contained in the lamp shape workstation 200, and workstation comprises the scanner head 204 and the flexible arm 202 of built-in printer 62.Workstation 200 is fixed on the supporting surface 106.Scanner head can be got in touch by antenna 206,208 usefulness radiowaves and terminal.Workstation 200 can the big commodity of scan volume, also can scan the petty commodities of sandwich and so on.And because little, structure is compact, has just saved valuable counter space, so just can provide bigger place for the client of shopping, for salesman's work provides bigger scope of activities.

Among the embodiment shown in Figure 5, the scanner head 102 of built-in printer 62 and flexible arm 108 both be not contained on the base station 104, were not contained on the supporting surface 106 yet, write down automatically on the terminal but directly be connected in the amount of money, and 132 of scales are contained on the counter top 106.

To the embodiment shown in Figure 5, figure is that the operator can use flexible arm 108,202, makes scanner head accurately on the scope of operation as Fig. 3, have between the commodity of bar-code marks and scanner head distance adjustable arrive optimum.In fact, the operator can pass through the commodity of the tape font code mark that will scan rapidly under scanner head, the operator there is no need repeatedly commodity by being located at the specific zones such as X-shaped groove on the table top, because, scanning head is to entire job face scan laser, groove formula scanister in the past requires commodity are passed through several times, so that bar-code marks alignment scanning light beam well.Among the present invention, the multi-direction scanner head of putting down in writing in the U.S. Patent application the 392207th (application on August 10th, 1989) number that scanning light beam is arranged is selected in suggestion for use, such scan mode and the product locations on the scope of operation are irrelevant, and the probability of the inswept mark of a branch of sweep trace is than high a lot of in the past.

The present invention also has characteristics that the automatic target perceptional function is just arranged.The scanning work station of Fig. 3～Fig. 5 is operation automatically.Scanning motion of the present invention must carry out continuously.In the workstation in the present invention, bar-code marks is detected, gives through infrared beam is dried, correctly decoded after, the data of expression mark are input to the POS terminal automatically.Display device all is presented at all processes in face of the operator.Commodity are in workstation, and sweep trace still continues the bar-code marks of items scanning.But, read be over after, send stop signal immediately, utilize typical infrared beams blocking-up method to prevent that a bar-code marks is read more than once.

Introducing Fig. 6 below, also is a portable scanner head 150, similar with above-mentioned scanner head 10, and built-in printer 62 is arranged.Can start with trigger 28.This scanner head 150 is connected to the amount of money by cable 152 and writes down automatically on the terminal 112, can take by hand, also can be contained in counter top and is on the support 154 on the supporting surface 106, and also can at least temporarily be placed on the little estrade 156 that stretches out from terminal 112 sides.Scale 132 can be placed near the terminal 112 the supporting surface 106.

If scale 132 work are separate piece, printer 62 is not contained in workstation scanner head or the portable scanner head yet, as shown in Figure 7, can all be contained in scale and printer in the box.In the subassembly 160 of scale and printer, comprise weighing platform 162, keyboard 164, display 166, and the outlet 168 of new mark 170.Built-in printer (wishing to drive with the bar-code marks input) is printed data 172 on each mark 170.Data can be used as one-dimensional bar code mark such as UPC mark coding, also can be used as bidimensional or the multiple track bar-code marks is encoded, shown in mark 170.No. the 4794239th, the detail with reference United States Patent (USP) of the multiple track bar-code marks that uses in order to utilize the space expeditiously.

Data 172 can be the information relevant with price, perhaps shown in mark 174, also can be the symbolic information that comprises the tired note of printer prints mark number of times serial number etc.Like this, the mark sum of energy print tracking just can help to have played antitheft effect.

Above-mentioned various scanner heads or each workstation can be worked under three kinds of patterns or state.The first kind of pattern that is called " inertia " is inactive state; The second kind of pattern that is called " aligning " helps the operator to penetrate to aim at and use light beam for the mark of correct aligning commodity.Alignment can form circle or elliptical spot or short lines on bar-code marks.The third is called " scanning " pattern, launches beam flying and reads whole mark.

As shown in Figure 8, principal computer 60 can be used for a plurality of scanner heads or 200 such workstations, in " scanning, printing, subsides are paid " operation, and the mark of each workstation items scanning, printing new mark can use separately, helps the operator that the mark of printing is attached on the commodity simultaneously.

If on the such single circuit substrate of substrate 54, except being provided with above-mentioned decoding/control device 56, other all parts in scanner head or the workstation are also all designed in the above, can be better.When use at during manufacturing or scene, a lot of conveniences are arranged, for example: microprocessor 30 can increase new control function, and if not, this is impossible, perhaps needs expensive hardware.

For example, when scanning head or workstation work, microprocessor can be controlled sweep amplitude (or sweep velocity) and the LASER Light Source as motor.If adorn a steady arm, give feedback of scanner, this just might realize automatic adjustment, thereby just can know also whether adjustment is correct.Rely on this automatic adjustment, saved staff's plenty of time and expense, and, because artificial error is prevented from, also can improve the reliability of indication of goods.

Because microprocessor is used for control, scan performance just can improve.Can change the gain of simulating amplifier with microprocessor, the speed of motor, digitizing thresholdings etc. are to help the difficult bar-code marks of reading of decoding.

Wherein, some are arranged is to lean on the decoding/control device away from scanner to change, and but, this just increases the connecting line between scanner and decoding/control device, and stube cable and connector take up an area of and expense has just increased.

Because code translator will be known the correct setting to its specific scanner, must not receive on other scanner, so during manufacturing, in order to adjust lasing light emitter and motor speed etc. automatically, decoding/control device and scanner are necessary all to be placed on the substrate.

To digital to analog converter, the digital control type that decoding/control device uses, the parts of potentiometer or attenuator, analog switch or other suitable controls are selected all its functions of may command of sign indicating number/control device.During manufacturing, correct setting in advance can be existed in the nonvolatile memory of microprocessor, when giving scanner one energising, this setting just can be restored.

See Fig. 9 below, sales counter 220 is all hung separately bar-code marks as putting a lot of ticbits (lifting several interior types) on the ticbit sales counter as fish 222, meat 224, Potato salad 226, cheese 28, salami 230, every kind of commodity, for example all is printed on standardization mark separately on the label 232,234,236,238,240.Through electrooptics scan, decipher, read, just can recognition value 222,224,226,228,230.

In addition, the amount of money counter 112 shown in Fig. 4 is arranged on the sales counter 220, antenna 208 is arranged, also have scale shown in Figure 7/groups of printers component 160, after the salesman stood in sales counter, hand was taken scanner 10 shown in Figure 1.

Introduce below and how to use, before client comes sales counter 220, buy certain commodity, one in general goal sausage as one wishes, the salesman weighs this root sausage, and scanner is aimed at label 240, is actually the system that tells, and the commodity of weighing are salami.By the optical identification of commodity, the mistake that number has caused with hand input product identifier before having avoided.Decided unit price according to commodity and weight thereof, stamped mark (as mark 170,174) is attached to (normally on its paper wrapping bag) on the salami to the mark of printing as mentioned above.

As a kind of improvement, on scanner 10, established a magnetic card and inserted seam 244, so that encrypt loan for the settlement of accounts the credit card from client's magnetic.

Because with above-mentioned method, which type of commodity all can carry out optically read, never is limited to the food sales counter so the present invention uses.Just can on scanner, add one as retail garment shop etc. and make the invalid device of label.
