Motor-driven disk camera

The present invention relates to simple in structure, economical and practical camera.This camera has a manual shutter start button, in order to film location, exposure, opens shutter, pilots engine then film disengaging exposure region is sent forward, and shutter is resetted.

Recently, the camera that the disc type film is used has been promoted by Eastman Kodak's gram (Eastman Kodak Company) and other company.The electric-motor drive device of this camera after cameraman starting, can make that film is in place, exposure and before give.This camera/film integration unit, the operation full automation, volume is little, can put pocket into, before bringing for the photograph fan convenience not.4,361, No. 387 United States Patent (USP)s investing R.Cloutier are exactly a structure example of this camera.

The camera that is applicable to the disc type film also has other type, and they all are the structure cameras more convenient than simple operations, utilizes that manual operation makes that film is in place, exposure, preceding sending.The U.S. 4,492, No. 443 patent has been introduced a kind of of this class camera.The camera of this patent is manually operated camera, has the characteristics identical substantially with the camera of Cloutier, but does not have the controller of motor and motor.This camera unicontrol makes shutter action earlier, after send film, very convenient.

Adopt other example of the camera of disc type film to also have the U.S. 4 in the prior art, 202, the another kind of manual operation camera and the U.S. 2 of No. 614 patent introductions, 625, the camera of No. 087 patent disclosure, this camera adopts the spool box of the disc type film of can resetting, and operates with a button: one drives shutter makes film exposure, before send film then, be the work of getting ready that exposes next time.But this camera makes film accurately locate when not exposing and film is unclamped before send the mechanism that gets ready for next time exposure.Therefore the location of this camera film is accurate inadequately, can not guarantee under any circumstance that photograph has very high sharpness.

Adopt other example of the camera of disc type film to also have in the prior art: upward disclosed camera of " research report " (Research Disclosure) in March, 1982 that warm secret service industry good opportunity company limited (Industrial Opportunities Ltd.) publishes number the 97th～98 page and the 100th～101 page is breathed out by Britain.This camera architecture is quite simple, compact, single button manual operation.But this camera is because structural limitation has reduced the convenience of operating.

The U.S. 4,492, economical and practical though the camera of No. 443 patent disclosures is simple in structure, there is potential shortcoming in easy operating: the long starting stroke of needs goes mechanically to finish the required various functions of camera.It is found that the starting process of this length is that the action of camera causes, the result can make resembling of breaking forth unintelligible.

As everyone knows, use miniature motor and realize that the part or all of function of camera can make the cameraman start camera fast easily, for example, the starting motor operated switch comes starting motor, but the patent of above-mentioned Cloutier adopts the electronic sensor and the controller of complex and expensive.

Therefore, the present invention provides driven disk camera.This camera architecture is simple, compact, economical and practical, but film is in place, send before the next film face with resetting of shutter all be electrically operated with single button.This design does not need the motor controller of complexity, costliness, can adopt the extremely short shutter start button of stroke, send device and shutter resetting means before the electronic film.

One object of the present invention just provides the driven disk camera with following array apparatus; Shutter winds up and releasing means, the film positioning device that send device before the film and can move between film bonding station and release position.Driver element has two opposite direction of motion.When the motion of first direction, shutter device is winded up, when second direction motion, make film positioning device move on to the position that discharges film, restart and send device before the film and film positioning device is returned to again on the position that film engages.The running of electronic device is moved driving element on first and second directions.

In addition, driven disk camera provided by the invention has following array apparatus: shutter winds up, releasing means, the film positioning device that send device before the film and can move between film bonding station and off-position.Driver element can wind up shutter when moving on first direction two opposite directions motions after shutter device starting, and when moving on second direction, mobile film positioning device is to the film off-position, send device before starting film then.After this, film positioning device moves to the film bonding station.By a cam and a cam follower lver that engages with driver element, during the electronic device running, driver element is moved towards first and second directions.Also arranging has a follow-up unit to contact with lever in order to flexibly to make driving element, thereby makes leverage impel driver element to move towards first direction, makes follower element impel driver element to move towards second direction.

Charging trigger lever 158 is contained on the post 128 under the battery chamber, can rotate around post 128, extends to the terminal 322 that links to each other with the charger circuit anode from the camera gate folding of the most close flashlamp loop one end.The folding of camera gate has a contact pin, when camera gate is in off-position, the engaged at end of this contact pin and charging starting lever, charging trigger lever is moved clockwise, thereby make the end that contacts with terminal 322 impel terminal 322 and charger charging arm 252 to break away from, thereby when camera gate is in closed condition, cut off getting in touch between charger circuit and the battery, reach the purpose of conserve batteries power supply.

When using the loaded camera of the present invention (handling method of film will be introduced in the back), open the lid handle of camera, camera lens and shutter release button are revealed.When the folding of lid handle each end around the battery chamber was rotated, the contact pin in the folding of flashlamp next door clockwise rotated charging trigger lever 158, promotes contact 322 itself and trip lever arm 252 are engaged, and charging circuit for flashlamp is got.As shown in circuit theory diagrams, " ready " signal lamp 360 is arranged in the circuit, signal lamp shows that to the user flash lamp circuit fully charges, and can carry out flash photographing.

When taking pictures, push shutter release button 16.Behind the button pressurized, board-like trigger lever is stuck in the also pressurized of end 180 in shutter release button rib 257 grooves 258, the trigger lever is rotated around pivot 176, be lifted at the board-like trigger quarter butt 178 of the other end simultaneously, and eliminate from the load pressure of press member 90 in the door 22 of camera.This exerted pressure press member in the past on pressure plate 44 in spool box, make the film film support framework 83 that bears down on one, and make film accurately in place in exposure plane, obtained best focusing sharpness.Meanwhile, the contact pin 238 on the arm 136 of the top of shutter release button rib 260 and trip lever 134 engages, and makes trip lever 134 toward pressing down, till the lower end of cam mechanism 154 lower surface upper protruding blocks 232 is crossed on surface 242.Projection 232 lower ends are crossed on surface 242 1, owing to storing spring force on the arm 250, trip lever just rotates around post 116 clockwise.Trip lever one rotates, and charger charge switch arm 252 just disengages with the plus end 322 of charger circuit, makes the charger circuit dead electricity.The rotation that spring arm 250 produces trip lever was enough to drive charger charging arm 252 originally and contacted with battery cathode terminal 318, just because shutter release button rib 257 is crossing with arm 252 before this contact takes place, and prevented that before camera shutter discharges contact from taking place, so charging arm 252 does not contact with battery cathode terminal 318.Therefore, camera shutter is finished after the exposure task, and motor could turn round.Similarly, because trip lever clockwise rotates, motor short circuit arm 254 breaks away from terminal 306.Equally, because trip lever clockwise rotates, the shutter release engagement pawl 246 on the arm 244 and lip 222 interlocks of shutter release 140, the shutter release inhour is rotated, discharge shutter release surface 216 thereby make, blade 136 is clockwise rotated under the effect of shutter spring 204 with the blade of lip 220 interlocks.At this moment the shutter release arm 244 stop pin 318(that impinges upon mechanism's backboard face sees Fig. 7 a to Fig. 7 c) further rotate and discharge the gland sheet occasionally to prevent trip lever.After blade 136 rotated about 36 °, the slope 218(that blade is smeared on the arm saw Fig. 8) contact with the lip 220 of shutter release 140, and along with blade continues to move forward, impel shutter release move be enough to discharge gland sheet 138 pull surperficial 217.At this moment, the exposure hole 212 on the blade is exposed, and film is exposed by camera lens.Simultaneously, the radial arm 205 contact flash synchronization contact (not shown)s of blade are connected flasher circuit, and lighting flashlamp is illumination for exposure.The gland sheet covers exposure hole by the part of pulling is discharged then, finishes exposure program.Blade falls within the shutter stop pin place of mechanism's backboard face and reaches static, and the gland sheet is clamped on the gland chip bonding sheet 213 on the blade.At this moment, whole exposure program has been accused and has been finished, but not further camera action before the cameraman decontrols shutter release button.

When the cameraman decontroled shutter release button, button mat shutter release button spring was got back to reference position, and the charger charge switch arm 252 of trip lever is contacted with the terminal 318 of battery cathode contact 314, thereby motor 160 is got.Direct motor drive crown gear 150, neutral gear 152 and cam mechanism 154.In the present embodiment, gear reduction ratio is 181.3 to 1.Cam 230 in the cam mechanism makes kinematic link 288 rotate around quarter butt 290, and by the engaging of drive lugs 190 on kinematic link end 292 and the driving element 188, thereby make driving element by first rotation counterclockwise.When the driving element counter-clockwise direction was rotated, blade winded up again, and the film trasport connecting rod is prepared film is sent forward.Specifically, driving element 188 inhours discharge pin when rotating and block release-push, hold up and fasten blade, and the film trasport ratchet promotes a tooth of transmission hub forward, stop to count the connecting rod cam and send forward around the lift cam of counting ratchet, energy is stored in the driving element spring.

In detail, when driving element begins to move by first direction, the end 266 of pin 156 is left in 194 motions of pin projection, pin is clockwise rotated under the effect of its spring, so rotate for 260 times to prevent that shutter release button is pressed once more in the film trasport process at the shutter release button rib end 264, when driving element continues when first direction rotates, shutter ear 192 and the blade ear 214 that winds up that resets engages, and clockwise direction driving blade is towards the position of holding up.The sheet 213 of gland sheet and blade also winds up when engaging again.When driving element reaches the solstics of first direction motion, the engaging arms 244 of pulling that trip lever reset arm 200 is mentioned trip lever makes it leave shutter release 140, when blade clockwise rotates, allow shutter release and shutter release composition surface 216 and the gland sheet faying face 217 of pulling to engage.At this moment, the film trasport ratchet 196 of driving element fast and another indented joint of ratchet 102.

Simultaneously, driving element is turned right, and to promote to stop to count lever 270 in place around the counting detent cam, mentions the counting ratchet when driving element begins to move by second direction.The motion of driving element also makes driving element spring 283 open, and stored energy is prepared to use when stopping counting and film trasport.

When motor was driven into cam mechanism kinematic link and is in the summit of protruding defeated salient angle, driving element rested on its original rest position inhour and becomes 37 to spend on the position at angles.This situation as shown in figure 12.At this moment, driving element spring 283 is in complete extended state, stops to count lever and blocks metering ratchet lift cam fast, film trasport ratchet and the next tooth interlock that drives the hub ratchet, pin is under the shutter release button, and blade winds up again, and trip lever just breaks away from shutter release.This situation only takes place in moment, is just introduced in order to say something at this.At this moment, motor does not stop, and remains in operation, and is driving the cam in gear train and the cam mechanism.When the process kinematic link of the summit of cam lobe (clockwise direction), cam can not continue to drive driving element, but and gear train and motor together, when energy stored makes driving element return its initial rest position by second direction in driving element spring 283, play controller.

When spring when second clockwise direction is held driving element, stop to count lever and cam 282 tension under photometry ratchet lift cam, counting pawl teeth 98 is mentioned from the metering groove of film plate edge.When the photometry pawl teeth was left film groove fully, the film trasport ratchet 196 on the driving element 188 began to rotate hub spare 84 and film dish.The film dish rotates at the beginning, stops to count lever and cam 282 from counting ratchet lift cam 172 beneath tensions, makes metering pawl teeth 98 down go to the film panel surface of rotating.During driving element convergence original rest position, the projection 194 on the driving element lower surface engages with the end 266 of pin 156, and inhour drives pin and remove the other end 264 under shutter release button 16.At this moment, the film dish before deliver to before next unilateral on, the next one that the counting pawl teeth is fallen on the next unilateral limit measures in the groove, make the action of film dish, hub 84 and driving element 188 stop, the tension force that is added on the driving element by actuator spring 183 makes the limit of groove withstand metering pawl teeth 98, till next shooting process begins.

The trip lever reset arm 200 of driving element 188 is also removed under the shutter release engaging arms 244 from the trip lever 134, returns on the position that can be resetted.

When driving element returned its reference position, motor remained in operation, and driving cam means engages with flange 240 on the trip lever arm 236 to living up to the projection on the plane, its underpart 232.Cam is rotated further, and trip lever is resetted.At first, charger charge switch arm is drawn back from battery cathode terminal 318, and motor is stopped.Motor and each gear continue inertia and rotate, until charger charge switch arm touches charging circuit terminal 322.This makes electric current continue by motor motor to be remained in operation, and touches terminal 306 until motor shorting switch arm 254, and the short circuit motor almost makes motor stop at once.Simultaneously, shutter release engaging arms 244 has been got back to its original position, is the starting next time of shutter release.Decontrol trip lever, to draw back shutter release ready.Bump bond flange 240 on the shutter release button engaging arms 236 of trip lever adjoins with cam mechanism projection 232, and spring arm 250 has been in case of bending can start trip lever 134 when shutter release button drives.

At this moment, motor is in the short circuit stop state, and charger circuit is in charging, and camera has been ready to take next photo.Charger circuit will continue charging, cover handle up to closing till, at this moment charger terminal 322 is separated with charger charge switch arm 252.

After the 15 of spool box and last film face exposure, film transport mechanism begins to promote the film dish forward, but just stops in middle of stroke.As mentioned above, the hub ear engages with the top edge of spool box ear, has stoped the film dish to be rotated further, thereby prevents driving element 188 clockwise repositions.Because pin is not removed under shutter release button, shutter release button is in blocking.Can remain in operation projection on cam mechanism of motor and gear train discharges restoring lever, cuts off motor and stop whole process.This is because because driving element is obstructed, the kinematic link action finishes, and cam lobe can be left due to the kinematic link.

Then, the cameraman opens camera, unloads according to spool box well, replaces new unexposed spool box.When door trip lever 20 clockwise rotates, following action will take place simultaneously: hidden slide link 182 rotates counterclockwise hidden sliding lever 184; The quarter butt 360 of door on the trip lever engages with arm 202 on the driving element, makes arm 202 remain on spool box and exposes locking fully and make on the position that arm 202 stops and the cam face 186 of hidden slide plate engages with the pin 170 that measures ratchet.When hidden sliding lever 184 rotated counterclockwise, hidden slip drive pin 37 was closed the hidden slide plate of spool box; Simultaneously, cam face 186 is pushed down the pin 170 of counting ratchet, counting ratchet 98 is withdrawed from, for the closure of hidden slide plate is cleared the path from the counting groove of film dish.Everything all takes place before decontroling the back door 22 of loading at the starting doorstop of loading.At this moment can unload according to spool box well, load onto new spool box.

New film is box-packed goes into after the camera, shuts the camera back door, costs doorstop 72, and this can rotate counterclockwise a trip lever.At this moment, hidden sliding lever 184 clockwise rotates, and opens the hidden slide plate of new spool box, and the counting ratchet 166 that counting tooth 98 is fallen on the film panel surface is broken away from.Simultaneously, the quarter butt 360 on the doorstop 20 is removed from the arm 202 of driving element, makes driving element spring 283 impel driving element 188 to clockwise rotate, and returns its initial rest position.This action drives ratchet 102 and hub of driving element make first unilateral position of going to exposure of virgin rubber reel.At this moment, the unilateral counting groove of counting pawl teeth this film of interlock.Like this, Camera system just turns back to its initial static position, can give first unilateral exposure of film at any time.

What introduce above is the handling method of the spool box that takes and the new spool box of not taking, the spool box of not clapped fully, and its handling method is just the same.Above-mentioned handling method does not have the risk of the fog that takes or camera machinery jam.

Though the present invention is introduced by most preferred embodiment, under the prerequisite that does not break away from basic thought of the present invention, it is conceivable that part body of the present invention is made amendment.For example, as can be seen from Figure 15, a drive element-driving element spring 283 between electric-motor drive device and the driving element is an extension spring in most preferred embodiment, can replace with stage clip 480.In the present embodiment, an end of kinematic link 488 has a two action cam follower 490.At the other end of kinematic link, on fulcrum 492 opposites, kinematic link engages with deep-slotted chip breaker on the driving element 496.In the present embodiment, kinematic link is in driving element when motion inhour, and with firm joint of an end of deep-slotted chip breaker, but kinematic link is oppositely when changing the direction of motion of driving element, and driving element drives driving element clockwise to the stage clip effect.Therefore, when the film gearing is in blocking, and driving element is when stopping to move clockwise, and spring is oppressed unlikely driving driving element by kinematic link, the carrying out of also unlikely interfere with motor 498, gear train 500 and cam 502 whole course of action.
