Description

The microfiche display equipment of selecting

The present invention relates to a kind of microfiche reader.Relate more particularly to a kind of reader of microprocessor-controlIed multiple mode, it can be in order or shows selected microfiche image with random fashion, and it comprises prompting and the timer that is used for selecting the image that will see.

Previous microfiche reading device generally needs the operator that microfiche is placed in the middle of two blocks of glass on the X-Y carrier movably so that the image on screen is manually located.Generally speaking, artificial removable index card uses together with the little plain film form of each hypertonic, index card is placed on this device, can give some not really desirable guidances of operator, inform where court carries out manual orientation with the X-Y carrier for desired image being placed on the viewing location on the screen.This method is that stochastic retrieval is to the main utility system that is stored in the information on the microfiche so far.Because explosive increase based on the new model of the information of microfiche, file as the computing machine generation, duplicate of the document by the word processor generation, and the sound that has of invention recently looks high-resolution color photograph microfiche and the colour map and the chart searching system of demonstration, this device accurately place with quick effective means aspect image and the visual demonstration not enough.

In the field of the visual and system of sound image that uses common 35mm or 2 * 2 slides and film band, the device of known technology is generally very heavy and operation is slow.Because the character of the permanent order basically of these visual systems, using this device with random fashion is difficulty and very slow.

Thereby feature of the present invention provides a kind of visualization system, and it can adapt to the colour or the black and white microfiche of many specifications, and can automatically accurately each selected image be placed on by artificial, that record or that computing machine produces prompting and watch on the screen.

Reader be mainly used in have as American National Standards Institute and national microfilm association (NMA) fixed standard microfiche film size (105 * 148mm) plain film.Yet, because the specification of microfiche also is not normalized into a special requirement, but can obtain plurality of specifications, so the device that can automatically make reader can adapt to all specifications that run into need be provided.This can realize in order to following method, and promptly taking a picture at the sheet Head Section of microfiche stamps bar code and row center line so that reader is applicable to the specification that will use.Perhaps when microfiche does not have preprinted head, then can on blank microfiche, take a picture and stamp bar code and center line uses together.The invention provides the optical devices of when microfiche inserts reader, reading bar code and center line.The other device that bar code is played response can move to the lens platform appropriate location selecting the correct enlargement factor of microfiche image then, and other devices can be set brightness and other relevant parameters of correct lamp.

According to further aspect of the present invention, this device comprises a plain film microscope carrier, and it has a view window to extend on the Y direction.Whole roller practically on directions X the inlet point from one side of device transport microfiche by the sensor that is placed on the view window center.This sensor scan and read out in the plain film top leader whole bar code and produce code for little processing about the specification of array on the plain film.The read-only memory that is composed of program (ROM) that forms electronic circuit component is composed of the data of representing all specifications that expectation can run into; Also can be sent in the device and microprocessor can automatically make its adaptation work according to each different size even plain film is the combination of different size.

Roller and microscope carrier are by direct motor drive, and its internal optics device feeds back to microprocessor with digit pulse.Additional digital information is produced by optical sensor, when plain film between sensor and light source by the time optical sensor is readable goes out the row mark that is imprinted on the sheet head region on the plain film.The row mark is positioned at each visual center.To compare with the information that obtains from motor pulses from the digital information of head sensor feedback to cause each image accurately to be located at its positive center.The narrow angle degree resolution sensor of reading center mark is placed on the front of plain film microscope carrier and in the central authorities at its two ends, and directly on groove top, by the considerable plain film of seeing of this groove.

The image of any ranks specification can both accurately be positioned at and watch on the screen, or in a sequential manner or with random fashion, or manually with straight visit order (default seguencl), or locatees in proper order with the preliminary election that is recorded on the tape.This class mode also can be selected and presents by the RS-232 interface on reader with outer computer.

Reader is followed a kind of straight visit order in sequential system, and wherein reader shows the plain film image from one jiao (visual A-1 or " family ") of plain film with S shape figure.Keyboard Control can or be used in prompting in sequential system, or carries out with the twotone cue.The twotone cue receives or is recorded in a sound channel of tape from telephone wire, and coordinates mutually with the sound accompaniment that is recorded in other sound channels.Provide RS-232 interface another input as the cue that comes from outer computer.

In straight visit order, when plain film is transported to the final image of given row, microprocessor makes the carrying platform move along its Y-axis plain film is moved to final image in the next line, and is at this X of place motor that stroke directions is reverse, and plain film advances to till the initiating terminal of this row.Use the method, plain film can be scanned with the S figure, causes like this demonstrating photographic image or reading material reposefully, easily.

In random fashion, reader is not followed the straight visit order of establishment on the electronics, and by given address of external signal and driving, above-mentioned outer signals is meant manual ringing, signal on the tape, remote signal or similar signal, these signal hypothesis are understood want position of image on microfiches, or the microfiche travel direction.

The element of sequential system and random fashion may be incorporated in the importation of reader.As only receiving the twotone cue, reader is presented at the next image in the straight visit order.As the twotone signal point out next image that the position of image in the cue front then shows will be by position signalling pointed select image.These two kinds of input modes can alternately be used for showing the separate section of single microfiche.The RS-232 input is handled in an identical manner.

The further feature of this device is to make image retrieve and look back in the mode of quick scanning forward or snap back, uses straight visit order in these modes.

The further feature of this device is the position (being the position of plain film) that a digital indicator is illustrated in the image that any given time watching.In random fashion, then provided the alphanumeric coordinate (A-1, C-4, D-17, etc.).The digital counter of (following straight visit order) when selecting sequential system is the numerical order of presentation image at the very start: 1,2,3,4, etc.Yet, can be in sequential system by " demonstration " key so as between two kinds of display modes Alternation Display.

The further feature of this device is that pressure system is housed on image plane, and this system includes image projection transparent presser feet in the past, thus when motor rotates or does not change the plain film image to remain between presser feet reaches glass platform at focal plane be flat.This just causes that each image is all had consistent focusing, thereby does not need to focus on again when seeing next image from an image.

The further feature of this device is the light intensity of microprocessor control projection bulb so that when not having image and show, bulb dark and to show visual in place the time just realize full brightness, can avoid the reader uncomfortable.

The further feature of this device is to produce the twotone signal that predetermined time interval is arranged when starting " prompting " control.Behind suitable cable and audio frequency jack, cue can be recorded on second track of the stereo magnetic tape cassette of standard and arranged side by side with sound visual range preface or commentary at first track.Any stereo cassette recorder all can be packed in this device and do not needed special sound-track engraving apparatus.The also available suitable connector of audio frequency jack is linked on the telephone wire for use in teleconference.

Pin 18 and 19 links to each other with tone detector (115) and tone producer (116) so that send respectively between reader and cassette recorder (203) and receive the twotone signal, or links the telephone wire breakout box so that open teleconference.The pin 21 of connector PJ1 send 12 volts of direct-current drive cassette recorders (203) (see figure 3) after pressing operation (RUN) key.Cassette recorder can be placed on the outside or be contained in the reader.Any cassette recorder commonly used is as all using for a kind of cassette recorder of Automobile Design or its equivalent.Shown in Fig. 8 B, cassette recorder (203) also has two audio frequency outputs on the pin 21 and 22 of plate (202), and a magnetic track of double track tape is with one.I.e. output is that the tone cue shows that with the prompting microfiche another output is linked loudspeaker and emitted the commentary relevant with microfiche or other data.Loudspeaker preferably is contained in the sound back, hole (506) in the audio amplifier (501), if or be ready also can be contained in the outside.

Connector (204) (PJ1) with the central processing unit plate on connector (128) (CJ2) interconnect.The connector (205) of connecting with switch (214) (PJ3) is linked projection lamp (518), presser feet spiral pipe (571), and fan (212) and connector (213) are so that provide 12 volts of AC power.Connector (206) is to export for the driving of Y motor (562) usefulness (PJ4).Connector (207) is to export for the driving of X motor (557) (PJ5).The presser feet interface shown in figure 32.

Fig. 4 represents four interfaces that four optical sensor 573-576 of reader use, and also is contained on the power panel (200).Connector (208) (PJ6) is linked sensor (573) with the pin 30 of PJ2, and this sensor is used for surveying carrying platform (544) and whether moves to backward extreme position on the Y direction, and promptly whether first of the plain film image row (510) is in viewing location.Connector (209) (PJ7) is linked PJ2 pin 28 sensor (574), and this sensor is readable to go out bar code (514) and row signs (516).Motor (557) and (562) all are interior optical motion sensor types, and the model of producing as available California Bai Erlingaimu (Burlingame) mark pine (Maxon) precision electric motor company is 44,040 motor.Connector (210) and (211) (PJ8 and PJ9) link PJ2 pin 8 and 6 sensor (575) and (576) respectively, and it can detect the rotation situation of X and Y motor (557) and (562).

Power panel (200) has detailed icon in the schematic diagram of Fig. 2 A and 2B.12 volts of AC power are linked power connector (213).Full wave bridge rectifier (215) and 1 filtering can produce 12 volts of direct currents with the electrolytic condenser (216) of 1000 microfarads.This voltage is by the power panel part of reference number for (217), i.e. a kind of input voltage of DC converter.One 20 kilohertz oscillator (218) (555) control transistor (219) is connected and is disconnected, so that produce 12 volts of square waves at transformer (220) primary side (TR1), and by transformer this signal boost is lied prostrate to about 30-35.This signal is by full wave bridge rectifier (221) rectification and by 1 microfarad electrolytic condenser (222) filtering then.12 volts of voltage stabilizers of two-stage (223) (78M12) and other voltage stabilizing element positive and negative 12 volts of DC voltage output is provided, this is the required power supply of RS-232 driver-transmitter (224) (75188).Transmitter (224) receives from the next numerical data of UART Universal Asynchronous Receiver Transmitter (114), and is sent to external device (ED) after being handled.

One 8 volts voltage stabilizers (225) (7808) are that two frequency-voltages (F/V) transducers (226) and (227) provide supply voltage.Frequency to voltage converter (226) is linked the pin 3 of PJ2, receives the X output of double trigger (123) pin 5 on the CPU board (100) at this place, and produces the drive signal that the X motor is used.The input of F/V transducer (226) is that dutycycle is 50% signal, its frequency needed VD when making X motor (557) with the motion of desired speed.Similarly, F/V transducer (227) receives Y output through connector PJ2 pin 10 from double trigger (123) pin 9, and is output as direct current signal, and its voltage is corresponding to the frequency and the desired Y electromotor velocity of input signal.Can obtain three kinds of output-voltage levels in fact and make motor drive signal usefulness, and the desired different driving speed of different modes that can provide the carrying platform to move: (1) operation (at a slow speed), (2) F.F. or snap back (middling speed), (3) and approaching fast, or at random near (all being quick) with directional bond.The output of F/V converter (226) is delivered to X motor (557) by NPN transistor (228).The output electricity NPN transistor (229) of F/V transducer (227) is delivered to Y motor (562).

The polarity of drive signal depends on delivers to the path that motor is walked with drive signal.X drive signal or by first pair of transistor (230a), (230b), or by second pair of transistor (231a), (231b) delivers to X motor (557).Y drive signal or by the 3rd pair of transistor (232a), (232b), or by the 4th pair of transistor (233a), (233b) delivers to Y motor (562).That pair of transistor conducting then is decided by the state of the Y motor direction signal of the X motor direction signal of connector PJ2 pin 16 and connector PJ2 pin 14.These signals all interface lock storage (120) from the central processing unit plate are received.For example, if X motor direction signal height, then transistor (230a) and (230b) conducting X motor drive in a side.If signal is low, then transistor (231a) and (231b) conducting, the X motor drives on other direction.

Draught fan (212) and projection lamp (518) can see also that in Fig. 2 B they link 12 volts of direct supplys at connector PJ3 place.Lamp (518) is driven by transistor (234), and this transistor is then driven by the narrow pulse output from the pin 3 of oscillator (235) (555).The brightness decision of lamp is in the pulse repetition rate of transistor (234), thereby its Dimmable.In this way, lamp deepening when microfiche moves between image is incident upon on the screen making us uncomfortable white light avoiding.Also provide low the 3rd pulse repetition rate to keep filament heat but only produce some lights or do not have light.The purpose of this feature is the life-span that prolongs lamp, if this lamp repeatedly repeat switch can burn out prematurely.

Be also shown in one 5 volts voltage stabilizers (236) in Fig. 2 A, it is the different digital element power supply that comprises RS-232 four-way receiver (237).The RS-232 receiver is received in the data-signal that connector (201) (PJ1) locates and (PJ2) locates to produce numeral output at connector (204) and deliver to central processing unit (CPU).

Each key is a single-pole single-throw (SPST) pushbutton switch.Keyboard also has connector (302) (KJ1), and the connector (127) on its connection central processing unit plate (CJ1); Connector (303) (KJ2) connects connector 402(DJ1 on the display board); Reach connector (304) and (KJ3) connect auxiliary keyboard, this dish can have 64 keys at most, but can see in Fig. 8 that in the present embodiment 16 keys are arranged.

In Master Keyboard, four keys " prompting ", " RUN ", " F.F. " reach " rewind down " and all use whole light emitting diode (LEDS) (307) to show.Light emitting diode in back three keys indicates denominative function to carry out, promptly, reader has " RUN ", " F.F. " or " rewind down " working method prompting light emitting diode (CUE LED) points out to have received cue, it is from tape, telephone wire, RS-232 line, remote control prompting switch, or " indication " key itself.Four luminescent diodes (307) by 220 Ohmages (308) link+5 volts of direct currents and C5-C8 between.Then the light emitting diode conduction is also light when pin C5-C8 step-down.

During button on pressing arbitrary keyboard, two logic chips, promptly keyboard buffer (305) and keypad lock storage (306) then are used for the state of surveying and keeping each light emitting diode.

Each key on Master Keyboard is arranged to four lines three row.Keyboard buffer (305) has eight row pin R1-R8; Each pin of R1-R4 pin is connected to each three interior voluntarily key on the keyboard.Each pin R1-R4 is through being connected to+5 volts of DC voltage at the 10K resistance of resistor assembly (308) in (UR1).Each pin voltage just often is high.The keypad lock storage has eight row pin C1-C8, and wherein three pins (C1-C3) are corresponding to each key in three row.A pin in the pin (C1-C3) on pin among the pin R1-R4 of impact damper (305) when the next key and the latch (306) is communicated with.Other pins on keyboard buffer and keypad lock storage are all linked the data sum.

60 hertz of transistor-transistor logics (TTL) keyboard interrupt signal is by counter/timer controller-A(CTC-A) generation.Each has signal to produce for the third time, promptly produced a signal every 1/20 second, central processing unit (CPU) produces all low input-signals and gives the keypad lock storage, and about 250 nanoseconds wide at the D0-D7 place, and a gating signal at pin 11 places makes pin C1-C8 become low signal.If any any one key corresponding pin ground connection among the pin R1-R8 then that is depressed, other gating signal on the pin 1 and 19 of keyboard buffer is delivered to low signal a pin among the pin D0-D7 of keyboard buffer, surveys it by central processing unit (CPU) at this place on data bus.Such as will be discussed below, central processing unit (CPU) in RAM, and is carried out function corresponding to the key of pressing thereafter with the sign note of the key pressed.Auxiliary keyboard (310) is linked same pin C1-C8 and R1-R8 and is read in same mode.

Keypad lock storage (306) also is the state that latchs light emitting diode (307) with central processing unit (CPU) logical circuit.When keyboard interrupt took place, this moment, all C1-C8 became low signal, made that all 4 light emitting diodes are all luminous.Very of short duration during interrupting, so that the scintillation of running fire optical diode all fails to find out, and CPU makes them turn back to state before it immediately.

Pin R1-R8 and C1-C8 can hold whole 8 * 8 auxiliary keyboards, and this keyboard can be connected to connector (304) (KJ3).Fig. 8 A is depicted as the 16 key auxiliary keyboards (310) of linking pin R1-R4 and C1-C4.

Fig. 9 is by the starting beginning, and it begins after energized or system reset.When step (603), the X motor moves to survey in the carrying platform whether microfiche is arranged slightly in a direction.Because bar code and row indicate it is transparent, and all the other leaders of microfiche are opaque, whether microfiche moves slightly just to be enough to distinguish detect and indicates or not plain film existence.As do not have plain film to exist, then set native system and have the microfiche of the standard specification of programming in read-only memory (ROM) in advance with reception.Exist if any plain film, then read the whole plain film head that comprise bar code from the beginning to the end, and specifications parameter is stored in the interior specification register of random access memory (RAM) (RAM).Specifications parameter comprises the number of image and arranges to reach whether plain film includes any non-standard specification zone.

Step 606 among Fig. 9 is the beginning that comprises the microfiche setting in motion or continue the series of steps of motion.Whether CPU decision microfiche is in motion on step 606.

As below will further discussing, with the operating and setting of the relevant control section of motion movement mark register MVIFLG and make microfiche begin to do appropriate exercise.Movement mark register MVIFLG is set in any motion that is necessary for generation.Referring to Figure 33, on step 720, counter/timer controller one A(CTC-A) periodically produces the motion look-at-me whether the decision motion should continue.The register that contains the existing position of microfiche when this signal produces is compared with the register that contains the desired position of microfiche, does not also then take any action the desired position of no show as plain film.Whether the basis of making this decision for having arrived the row mark, perhaps the pulse of whether having received anticipated number from X and Y motor sensor.When on directions X, moving,,, thereby before arriving, the step-by-step counting of expection arrives the row mark so that allow sliding of roller 551-554 to the intentional too high estimation of umber of pulse of expection.The position reaches as required, then removes the movement mark register, and all motions stop.

Get back to Fig. 9, on step 606, if motion stops, then central processing unit (CPU) is checked its flag register, whether begins other function with decision.When from tape, telephone wire, the RS-232 line when " prompting " key on the Master Keyboard or external prompt switch receive cue, is set " prompting process " flag register.Connect as " prompting process " flag register, and if central processing unit (CPU) but prepare doing motion, then the carrying platform takes plain film to will show next image, and " prompting process " flag register is turned off.When step 601, connect as F.F. (FFW) flag register, then reader enters next image in proper order with middling speed and with straight visit.On step 612, connect as snap back (REW) flag register, then reader moves to former image with middling speed.

After these operations, on step 614, central processing unit (CPU) determines whether to have key and presses.Such as previously discussed, as counter/timer controller one A(CTC-A) then keyboard is polled when producing keyboard interrupt signal, and as pressing the then low state of appearance on data bus of any key on the keyboard.When this signal produces corresponding to by by the numerical value of key be stored in the random access memory (RAM) (RAM) with mark KBRDATA.

The keyboard interrupt program has more detailed elaboration in Figure 10.When keyboard interrupt takes place, then on step 619 decision whether point out light emitting diode (CUE LED) bright, this lamp can indicate received at that time cue or by the prompting key.This situation also makes the cue flag register be set.If prompting light emitting diode (CUE LED) is bright then on step 620, the amount of the prompting random access memory (RAM) (CUERAM) in random access memory (RAM) subtracts 1.CUERAM begins on a preset value, makes prompting light emitting diode (CUE LED) keep connecting the desired duration so that provide.For example, will keep connecting half second as prompting light emitting diode (CUE LED), CUERAM should begin to be set in 30, because the frequency of keyboard interrupt signal is 60 hertz.On step 621,, then point out light emitting diode (CUE LED) lamp to go out when CUERAM equals 0.On step 624, connect as prompting light emitting diode CUE LED, and be not equal to the cue of 0 generation twotone as CUERAM.This cue can be recorded on the magnetic tape cassette, or can not use in order to point out another microfiche reader.The tone prompting proceeds to quantity CUERAM to 0.

In step 627, as by key then by by the mark KBRDATA of key on step 632, read.If by key be not " stopping " (STOP) combination of key and the orienting arrow key pressed at the same time, then whether decision is connected and is played flag register (DEBFLG) on step 638.

Remove to play flag register and be and finding out for the first time, and keep connecting till key is released (step 628), thereby prevent single keys presses and repeatedly handle by the flag register that sets during key (step 642).This is to be used for the pattern of latch technique of the contact spring in the compensating switch; So called after " removes bullet ".In step 638, as remove to play flag register (DEBFLG) and do not connect, then do not find out as yet before the explanation by crossing key or key not being arranged as yet by by mistake.On step 640, table look-up seek by by by the subroutine that key called read-only deposit the address of demoting in the device (ROM).On step 641, replace KBRDATA then with this address.On step 642, set and remove to play flag register (DEBFLG) representing existing button one thing present, and set keyboard flag register KBRFLG and be present among the random access memory (RAM) (RAM) with indication KBRDATA.

Referring to Fig. 9, on step 614, connect again, then carry out keyboard analysis subroutine KBRANA as keypad indicia register (KBRFLG).This can see in Figure 11.On step 681, from random access memory (RAM) (RAM), read KBRDATA.On step 682, from random access memory (RAM) (RAM), read out in the subroutine of the address in the KBRDATA; And on step 683 execution subroutine.On step 684, keypad indicia register (KBRFLG) is resetted, and set the show tags register so that any necessary variation of beginning show state.On the step 616 of Fig. 9, to connect as the show tags register, then update displayed, and central processing unit (CPU) is waited for other instruction.

Again referring to Figure 10, on step 638 as having leant out button one thing but remove to play flag register DEBFLG and connect, then owing to handled, so can ignore this thing.When in step 627,, then will remove to play flag register (DEBFLG) and be reset to 0 when no longer leaning out button one thing.Central processing unit (CPU) is checked the arrow mark register then, if it is set after having used positioning key.As setting the arrow mark register, then directional bond has been pressed in this explanation, but discharges now.Motor stops, and keyboard interrupt finishes.

Referring to step 633, utilize the combination of " stopping " key and directional bond to adorn the microfiche that does not have bar code or specification to fail to understand, and make first image suitably be placed on central authorities with the position of directional bond fine tuning plain film.Make then to play flag register (DEBFLG) and reset, set arrow mark memory, and on step 635, carefully moving on required direction.On step 636, set the position of the register of random access memory (RAM) (RAM), show with first image of indicating microfiche.

The subroutine that Figure 12-15 expression is carried out according to orienting arrow.Upwards subroutine as shown in figure 12.Because desired mode of operation is retrieval or enters fast so that show the image that needs especially, so with brightness settings in the high brightness position.On step 646, even reduce Building Y mark carrying platform, thereby reduce the Building Y target value to the motion of the rear portion of reader, back on top or the row of " family " is arranged.Check at first whether target revision value in Building Y has dropped to below 0 with decision; In eight bit register, be 256 just in time in the value below 0.If like this, then set the Building Y and be designated as 0, and finish to move upward.Not below 0, then select the speed that enters the soonest as coordinate, set the movement mark register, the directed standard register of decision Y motor direction of motion is resetted, motion continues, up to found out button one thing on step 627 till.

The subroutine of the directional bond of response downward (DOWN) as shown in figure 13.This upwards function class general and previously discussed seemingly, different is not need to check zero coordinate, step 656 inspection judges that whether next Building Y mark can surpass the maximum Building Y mark that the specification according to microfiche preset.

Left (LEFT) and to the right (RIGHT) subroutine in Figure 14 and Figure 15 respectively the diagram.They are general and upwards reach downward function class seemingly.

Load (LOAD) subroutine as shown in figure 16.Connect the presser feet electric current presser feet (569) is risen, put plain film into so that between presser feet and platen, stay the space.Rotate the X motor till barcode sensor (574) detects opaque head (512).On this aspect, begin to read head, and to lean out any transparent part be bar code or row mark.On step 691, from the information of the relevant plain film specification aspect that bar code obtains, such as line number, columns and the zone that any non-standard specification whether occurs all deposit the specification register in.

Then microfiche is moved to ultra-Left and extremely back position so that show the A-1 image, put down presser feet, the turn-on lamp power supply, and set the brightness adjustment.

Figure 17 represents to move back sheet (EXIT) subroutine.Presser feet rises, and tepid state is transferred in brightness, and the carrying platform moves to rearmost Y limit place, releases plain film, and the carrying platform is got back to position A-1, removes all flag registers, and light emitting diode goes out, and puts down presser feet.

In prompting subroutine shown in Figure 180, check that at first operation flag register (RUNFLG) is to determine whether by operation (RUN) key.As do not press, then no matter the prompting key.As setting the operation flag register, then set motor speed, set the cue mark register (CUEFLG) of control prompting light emitting diode, and set prompting process (CUE PROCESS) flag register so that start the motion on step 607 among Fig. 9.And the setting prompt time is with the duration of light emitting diode on step 619-626 among decision Figure 10 and prompting tone.

In Figure 19, when by operation (RUN) key, set operation flag register (RUNFLG) in the boot sequence mode.Set to show that so that the display digit data, F.F. and rewind down flag register reset, and set electromotor velocity so that order shows, set the brightness situation of projection lamp.
