SHEET 8 UF 8 SF A 7 fig. 32 ZJ 0?. W fi yw FICHE-TO-FICIIE CQFIER The present invention relates to record copying devices and more particularly to apparatus for making card-like record copies of, for example, the fiche type.

The storage of information, particularly documentary information, in the form of microimages on photographic film is a common and wide-spread practice. This practice usually involves the provision for a film master file system in which master copies of the documents are stored. The present invention relates to apparatus, particularly for use with such systems, and in which copies of the master files are made on discrete card like forms. Typically, the card-like forms are rectangular file cards in which the information is usually recorded photographically on a transparent portion thereof. These cards are frequently of the type known as aperture cards in which a mounting material, usually opaque and of a paper type substance, defines the shape of the card, and which has at least one aperture formed therein in which is contained a transparent film insert. Another common type of card is that of the fiche type, in which the transparent film material defines the entirety of the card. The present invention is directed toward a copier which is applicable to making copies on various types of such cards, but includes features which are specifically useful in making copies of fiche type cards in which substantially the entire area of the card may be exposed to information from the master copy.

It is a primary objective of the present invention to provide a card copier wherein a complete copying process can be performed in a rapid and compact operation.

A more specific objective of the present invention is to provide a copying apparatus in which the supply of copying blanks, the exposure station at which the copy blank is exposed to information from the master file, and a developing station which renders the latent image formed at the exposure station permanent are related and positioned in such a way as to fonn a highly compact and efficient device. More specifically, it is an objective of the present invention to form an efficient and compact device in which photosensitized copyv cards having for example a diazo coating, are fed to an exposure station whereat exposure is made by, for example, a contact printing process, and to a developing station whereat the exposed coating is developed by application of a developer such as pressurized anhydrous ammonia vapor subjected to the card while a sealed developing chamber. 7

It is one specific objective of the present invention to provide an apparatus in which the above objectives can be accomplished in making fiche copies of master files, and particularly from other fiche type masters, which allows exposure of substantially the entire area of the copy card.

The present invention is predicated on the concept of providing a compact copying device wherein the copy card storage magazine, the exposure station, the developing station, and the delivery or discharge means are positioned along a generally U-shaped path of travel through which the copy cards, when traveling, will be maintained in a generally vertical plane. More specifically, each of the stations is situated along a different straight portion of the path so that the copy cards at those stations are maintained in a substantially flat vertical plane. The stations are connected by conveyor devices through which are defined curved trackways or guides along which the cards are advanced from station to station. Means are provided for bringing the master files to the exposure station and clamping them into contact with the copy cards and exposing the copies to the source of radiation projected through the master copy.

The present invention is further predicated in part upon the concept of providing movable drive rollers which operate to carry the copy card into and out of the exposure station and which are maintained in a normal driving position such that the copy card is always engaged by at least one pair of such rollers, and which rollers are movable away from the copy card during the exposure process to prevent the shielding of the copy card from the exposing radiation and thereby allowing exposure from substantially edge-to-edge of fiche type copy cards.

The advantages of the present invention reside in the provision, ,in a copying device which provides a complete copy process, of an operation of exceptional compactness heretofore not provided by devices of the prior art. Furthermore, the device of the present invention provides for the full exposure of fiche type copy cards during the copying process.

These and other objectives of the present invention will be more readily apparent from the following detailed description of the drawings illustrating one preferred form of a record copying device of the ficheto-fiche copier type which embodies principles of the present invention.

FIG. ll illustrates one specific embodiment of a copier which is of the fiche-to-fiche copier type according to principles of the present invention, that is, in which fiche copies are made from fiche masters. While the present invention is described in relation to this specific embodiment, certain principles of the invention are applicable to copiers in which card copies in general are made from masters of various forms. For example, the copies may be cards of the fiche type, or may be aperture cards in which one or more transparent inserts are carried by a paper mount, or may be other discrete card-like copies. The masters from which the copies are made, on the other hand, may be in the form of cards such as the fiche or aperture cards, or may be in the form of webs such as rolled microfilm.

Referring to FIG. 1, the copier includes a horizontal base mounting plate 11 to which is rigidly secured a vertical mounting plate 9. To the plate 11 is secured a plate 11, and an exposure and light housing assembly 16 mounted to the vertical mounting plate 9. An advancing conveyor assembly 17 is mounted to the base plate 11 and positioned opposite the exposure station 14 from the feed conveyor 13. The advancing conveyor 17 operates to advance exposed cards from the exposure station 14 to a developing station 18 which is mounted also to the base plate 11. A delivery conveyor 19 is mounted to the base plate 11 opposite the developing station 18 from the advancing conveyor 17. The delivery conveyor 19 operates to feed exposed and developed copies from the developing station 18 to a delivery tray 20. As shown in FIG. 1, the delivery tray 20 may take two forms. The form20A illustrated in solid lines in FIG. 1 represents a delivery tray of the type which will present the individual finished copies to the operator for removal and for this purpose is providedwith an accessible opening 21. The alternative form 20B is illustrated in phantom lines in FIG. 1 and represents a stacker type hopper which will accumulate finished copies in a stacked'relationship for their later removal by the operatonThe hopper 20 is also rigidly mounted to the base plate 11.

Referring to FIG. 2, the supply magazine 12, the feed conveyor 13, the exposure station 14, the advancing conveyor 17, the developing station 18, and the delivery conveyor 19 are more completely illustrated. These components operate to form fiche copies from fiche masters. The masters are, retrieved from storage and transported to the exposure station 14. Then, one or more copy cards are sequentially fed to the exposure station 14 where they are exposed to the, image of the master card, then fed to the development station 17 where they are developed to'render the latent images of the master visible, and then they are discharged at the delivery hopper 20. After all desired copies have been made, the master is returned to its storage area. Unexposed fiche copy cards are stored at the supply magazine 12. When a copy of a master which has'been fed to the exposure station 14 is desired, a fiche copy card is fed from the magazine 12, advanced by way of the feed conveyor 13 to the exposure station 14, where it is urged into contact with the maste'rby actuation of the copy card handling portion of the exposure station 14. The copy card preferably carries a diazo coated photosensitive surface which will preferably face the master during exposure. At the exposure station 14, this surface is exposed to ultraviolet light from the light source portion 16 of the exposure station 14, and then the copy card released from the exposure station and fed by way of the advancing conveyor 17 to the developing station 18, where it is developed by contact with pressurized anhydrous ammonia vapor. Upon way of the delivery conveyor 19 to the discharge outlet 20.

The cards of copyable fiche material are maintained in the magazine 12 in a vertical orientation and, when advanced, proceed in a U-shaped path along the feed conveyor 13 and maintain their vertical orientation through the exposure station 14 along the advancing conveyor 17 and through the developing station 18. In this manner, copies can be made in an efficient and compact operation.

The unexposed copy supply magazine and feed mechanism 12 includes a U-shaped tray portion 31 having a base 32 rigidly secured to the machine base mounting plate 11 and having perpendicularly upstanding side walls 33 which terminate in inwardly projecting flanges 34 at the upper ends thereof. The tray 31 is adapted to surround and contain a stack of blank unexposed fiche cards 36. The stack of cards 36 is compressed between a feed plate 37 and astacker plate 38. The stacker plate 38 is urged toward the feed plate 37 by springs 30 or any other suitable mechanism. The feed plate 37 is slideably supported to a fixed end plate 35 rigidly mounted on one end of the tray, and is adapted to move in a reciprocating motion horizontally through an opening 40 in one of the walls 33 and toward the feed conveyor assembly 13 (FIG. 3). In FIGS. 2 and 3, the plate 37 is shown in its extended position with its leading end 39 in engagement with the conveyor assembly 13. The plate 37 is provided with a step 41 in its face adjacent the stack 36 which presents a vertical edge engageable with the end card on the stack 36. The width of the face of the step 41 is slightly less than the thickness of one of the cards 36 so that, as the feed plate 37 reciprocates, engagement is made with: one of the cards to push it toward the feed conveyor assembly 13, but so as to only feed one card and to separate it from the stack 36. The opening 40 in the end 33 of the tray 31 is slightly greater than the combined thickness of the feed plate end 39 and a single one 42 of the cards.

The plate 37 is reciprocatably driven by a motor 44 rigidly mounted through a gear housing 45 to the base plate 11. The gear housing 45 has an output shaft 46 which extends-through a bracket 47, whichis rigidly supported to the base plate 11, and terminates in an eccentric coupling element 48. The element 48 has an output shaft 49 which projects into a slot 50 in the plate 37. This will be better shown by reference to FIG. 3.

FIG. 3 shows a card blank 42 broken away to expose the feed plate 37 slideably mounted to the tray end portion 35. The slot50 in the feed, plate 37 is vertically oriented and is adapted to receive the shaft end 49 of the eccentric element 48. In this manner the rotary motion of the eccentric 48 is translated into reciprocating linear motion of the feed plate 37. As the eccentric element 48 was rotated to the position shown in FIG. 3, the card 42 was engaged by the notch or step 41 and advanced to the right as shown in the figure. Upon return motion of the eccentric 48, slide plate retracts to the left in the figure. Upon this return motion, the eccentric 48 actuates a limit switch 52, mounted on the bracket 47, to stop the motor 44 with the feed plate in its rest position.

ends of an arcuate guide path 63 by a distance slightlyless thanthe length of one of the cards 42. In this manner, a copy card 42 can be advanced through the feed conveyor 13 while always remaining in engagement with one of the

pairs

61 or 62 of rollers. Control of the copy card 42 in its vertical attitude is maintained by upper rollers and path (not shown).

The guide path 63 is a slot formed in a block 64 rigidly mounted to the base plate 11. The slot 63 is defined by an inner convex guide surface 65, an outer concave surface 66, and a bottom. The bottom is located above the base plate 11 and is co-planar with the top of the tray base 32. The upper guide paths block 64A (FIG. 1) is mounted to a bracket 67 and is parallel to the block 64 so that its slot is overlying the slot 63.

The roller pair 61 includes a driven roller 71 rotatably mounted upon a shaft 72 next to the base plate 11, and an idler roll 73 rotatably mounted upon a shaft 74 carried by a pair of leaf springs 75 mounted at their ends to the block 64 to bias the idler roll 73 against the driven roll '71. The upper ends of the shafts 72, 74 are journalled in the upper block (not shown) and carry the upper rollers (not shown).

The roller pair 62 includes a driven roller 76 rotatably supported by a shaft 77 which is carried by the base plate 11, and an idler roll 78 rotatably mounted upon a shaft 79 which is carried by a bracket 80 pivotally mounted upon the shaft 77. An upper bracket (not shown) is similarly attached to the shafts 77, 79 at their upper ends and carry similar rollers.

The driven rollers 71 and "76 of the roller pairs 61 and 62, respectively, are provided with driven sprockets 81 and 82. About these sprockets 81 and 82 extends a driven chain 83 which also extends around a sprocket 84 driveably supported upon a shaft'86 of an electric motor 87. Energization of the motor 87 drives the rollers 71 and '76 through the chain 83 to feed a card 42 through the nip of the roller pair 61 as the card 42-is fed from the magazine 12 to advance the card through the nip of the roller pair 62 and into the exposure station 14.

A limit switch 88 is mounted to the base plate 11 and has a feeler arm 89 positioned along the path 63 to provide means to signal the feed of a card into the exposure station 14.

The advancing conveyor 17 is similar to the feed conveyor 13. The upper elements of this conveyor are not shown, but it is to be'understood that they are identical with the lower'elements which are described in detail. The conveyor 17 includes two pairs of

rollers

91 and 92 spaced at opposite ends of a guide path 93 formed in a lower base block 90. The slot is defined by a convex guide wall 94, a mating concave guide wall 95, and a bottom co-planar with the bottom of slot 63. The upper guide block 90A (FIG. 1) is mounted upon a bracket 96. The roller pairs 91 and 92 are spaced apart by a distance less than the length of the card 42 so that the card passing through the advancing conveyor 17 will always be under the control of one of the roller pairs 91- or 92.

The roller pair 91 includes a driven roller 101 and an idler roller 102. The roller 101 is rotatably mounted upon the shaft 103 which is supported by the base plate 11. The idler roller 102 is mounted upon a shaft 104 which is supported by a pair of brackets 105 pivotally mounted to the shaft 103 and spaced at opposite ends of the roller 101.

The pair of rollers 92 includes a driven roller 11 1 and an idler roller 112. The roller 111 is rotatably mounted upon the shaft 113 which is supported by the base plate 11. The idler roller 112 is mounted upon the shaft 114 which is also supported by the base plate 11. The

rollers

101 and 111 are provided with drive sprockets 117 and 118, respectively, each surrounded by a driven chain 119 which surrounds a drive sprocket 120 of the shaft 121 of an electric motor 122. Operation of the motor 122 drives the roller pairs to withdraw a copied card from the exposure station 14 and feed it along the path 93 through the rollers 92 and to the developing station 18.

A limit switch 125 mounted to the plate 94 is provided with a feeler arm 126 positioned along the path 93 to signal the advancing of a card through the advancing conveyor 17 to the develop station 18.

At the exposure station 14, a copy card 42 which is photosensitized with a diazo material is exposed by ultraviolet light to the image of a master card which is presented to the exposure station. The master card is retained in contact with a glass window 127 at the support wall 9 by a pair of

guide members

123 and 124. The copy card, when initially presented to the exposure station 14, will be held in a slot 128 (co-planar with the bottoms of slots 63 and 93) in the copy card handling portion 15 of the exposure station 14, and will have its opposite ends gripped by the roller pairs 62 and 91. The portion 15, as will be explained in more detail in connection with FIGS. 5 and 6, urges the copy card 42 into directcontact with the master card against the glass window 127. In order to provide a more complete contact between the master card and the copy card, and thus a more complete exposure of the copy card, the roller pairs 62 and 90 are adapted to retract from engagement with the edges of the copy card through the pivotal action of the

levers

80 and 105 respectively.

'As discussed above, the

levers

80 and 105 are pivotally mounted about the

axes

77 and 103, respectively, of the driven

rollers

76 and 101 respectively. When these levers are in the position illustrated in FIG. 2, the

idler rollers

78 and 102 block the edge regions of the copy card from exposure to the ultraviolet light impinging through the master card and the window 127. During exposure, however, the

levers

80 and 105 will take the positions illustrated in FIG. 4, in which the idler rolls have been pivoted away from each other and out of the path of the light impinging upon the edges of the card 42.

Referring to FIG. 4, the ends of the

levers

80 and 105 opposite the idler rolls 78 and 102 are provided with

pins

131 and 132, respectively. The pins are adapted to be received by L-shaped

slots

133 and 134, respectively, in the ends of

links

135 and 136, respectively. The

l39 in the

links

135 and 136. The opposite ends of the

links

135 and 136 are pivotally mounted at

points

141 and 142, respectively, to an arm 143 attached to a shaft 144 of a rotary double-acting solenoid 145. When the solenoid is in the position illustrated in FIG. 4, the idler rollers are withdrawn from contact with the copy card, and when in the position of FIG. 2, the idler rollers are inengagement with the copy card.

The respective positions are monitored by a pair of

limit switches

151 and 152, respectively, having

actuators

153 and 154 positioned to engage a projection 155 on the lever 135.

The details of theexposure station 14 are shown in the vertical cross section view of FIG. 5. In this figure, the exposure station is illustrated in an unloaded condition. The copy card handling portion 15, supported on the base plate 11, is illustrated in position ready to receive an unexposed sensitized copy card. The vertical support plate 9 is illustrated'having an aperture 161 therein ready to receive a master card to be copied. The light source 16 includes a housing 162 rigidly mounted with respect to the support 9 containing the ultraviolet light which directs ultraviolet radiation through the glass 127, the master card, and the aperture 161 to expose the copy card supported by the copy support portion 15.

The master card handling mechanism is adapted to receive a selected master'card from a tile. The selected master card is presented at a pair of rollers 165, for example, which may be part of a conventional card selector device such as that disclosed in U. S. Pat. No. 3,536,194 of Warren D. Novak, entitled DOCUMENT RETRIEVAL AND HANDLING SYSTEM. The rollers 165 present a master card 167 with its upper edge in engagement with the nip 168 of a pair of rollers 170 which include'a drive roller 171 and an idler roller 172. The roller 171 is rotatably mounted upon a shaft 173 which is mounted in the vertical support plate 9. The idler roll 172 is rotatably mounted upon a shaft 174 which is mounted upon a support plate 177 which is rigidly mounted with respect to the vertical support plate 9. Similarly, a pair of upper rollers 180 is provided which also includes a drive roller 181 and an idler roller 182, each respectively rotatably mounted upon a pair of

shafts

183 and 184 to the

plates

9 and 177, respectively. These rollers are spaced above the set of rollers 170 a distance less than the height of the master card 167 so that control of the master card 167 is always attained by at least one of the pairs of

rollers

170 or 180. The

drive rollers

171 and 181 are provided with a pair of pulleys around which is received a drive belt the nip of the rollers 180. An aperture plate 191 is pivotally linked at point 192 to a linkage 193 which is in turn pivotally mounted at point 194 to a bracket 195 rigidly supported to the top of the housing 162 of the light source 16. A leaf spring 196 is provided having a free end urged against the side of the plate 191 and its other end constrained rigidly to the housing 162 of the light source 16. The lower end of the plate 191 is urged against an abutment surface 197 of the housing 162 by a spring 198 connected in tension between a hook 199 rigidly mounted to a bracket 201 supported rigidly upon the plate 177, and a hook member 202 at the base of the aperture plate 191.

A solenoid 206 is rigidly'supported upon a horizontal leg 205 of the bracket 201 and has its output shaft 207 pivotally connected at point 208 to one end of a lever 209. The lever 209 is pivotally connected at its center at shaft 210 to the bracket 201. The free end 21 l of the lever 209 is provided with a projection 212 which, in cooperation with the end 211 of the lever, is adapted to engage an abutment plate 213 mounted at the lower end of the aperture plate 191. When the solenoid 206 is de-energized, the lever 209 and the aperture plate 191 are in the positions shown in FIG. 5 and a switch 204 within the solenoid 206 is-tripped. A switch 216 having a feeler arm 216 is mounted to the plate 177 so that its arm detects a card's presence or absence from the feed channel between the

plates

9 and 177. The switch 215 functions through suitable timing (to be described) to energize and de-energize the motor 190 and solenoid 186 which is directed around a drive pulley 187 and a tension pulley 188. The pulley 187 is mounted upon a shaft 189 of an electric motor 190. When the motor The aperture plate 191 has an aperture 220 therein over which is mounted the glass window 127. At the lower end of the aperture plate 191 is a horizontal lip portion 221. When the solenoid 206 is energized, its actuator'207 moves to the right in the figure, and the upper end 211 of the lever 209 moves to the left in the figure, causing the lip portion 221 to extend beneath a master card which will be positioned with its lower edge between the nip of the rollers 180.

'A solenoid 231 is rigidly supported to the top ofthe housing 162. The actuator 232 of the solenoid 231 is connected through a pivotal linkage 233 to a point 234 on the link 193. When the solenoid 231 is actuated, its actuator 232 will move to the rightin the figure, causing the link 193 to pivot clockwise and to elevate the aperture plate 191. This action will occur, during operation, after the actuation of the solenoid 206, thus insuring that the lip 212 will be engaged with the lower edge of the master card 167 so that the aperture plate 191 will be lifted and thereby lift the master card 167 to a position centered with the opening 161 in the plate 12. As the plate 191 moves upwardly, it is urged into the opening 161 of the plate 12 by pressure exerted by spring 196 to press the master card against the

guides

123, 124. When properly positioned as illustrated in FIG. 6, the plate 191 will close a switch 230 (FIG. 1).

Returning to FIG. 5, the copy card handling portion 15 includes the slot 128 defined on one side byopposing upper and

lower portions

241 and 242, respectively, of a card support housing 143. The housing 243 is slideably supported upon a shaft 244 through a slide bearing 245 and is also slideably supported near the flange ends 241 and 242 upon a pressure plate 246 rigidly secured by a bolt 247 to the end of the rod 244.

The rod 244 is in turn slideably supported on a pair of bearings'251 and 252 carried by a mounting support 253 rigidly supported upon the base plate 11. The pressure plate 246 is provided with a rubber facing'cushion 255 which defines the other side of the slot 128. A spring 258 is compressed between the bracket for bearing 251 and the housing 243 to urge the housing 243 toward the pressure plate 246 such that upper and lower edge portions 259 of the housing 243 are in engagement with the pressure plate 246.

A motor 261 is provided having an eccentric plate 262 connected to its output shaft 263, and an eccentric pivot pin 264 mounted thereon for pivotal attachment of a link rod 265 which is pivotally attached at its other end by a pin 266 to the end of the rod 244. The motor 261 is mounted to a support bracket 267 fixed to the base 11. Rotation of the motor 261 reciprocatably drives the link 265 to reciprocate the shaft 244. This action moves the housing 243 and the pressure plate 246 from the position shown in FIG. in unison to the right of the figure until the

flange portions

241 and 242 of the housing 243 come into engagement with the support plate 9, at which time the pressure plate 246 continues its motion to the right while the housing 243 comes to rest against the plate 9 to compress the copy card against the glass plate 127 which is positioned in the aperture 161 of the plate 9. This position, with the master card 167 and the copy card 42 in place, is illustrated in FIG. 6.

A pair of

plates

271 and 272 are attached to the rod 265 in such a position to actuate

limit switches

273 and 274 by contacting their actuators 275 and 276 respectively, as the assembly is in its retracted position of FIG. 5 and its actuated position of FIG. 6, respectively. A shutter control 236 including a timer 237 and suitable linkage 238 exposes the compressed copy card and master card to the ultraviolet light for the prescribed time duration.

Referring again to FIG. 2, the development section 18 is illustrated and includes a fixed platen 301 rigidly mounted to the base plate 11 and a movable platen 302 having a planar surface adjacent the surface of the fixed platen 301, and slideably supported on the base plate 11 to move into and out of pressure engagement with the fixed platen 301. The movable platen 302 is supported and biased by conventional means (not shown) away from the fixed platen 301. When in its normal position, as illustrated in FIG. 2, a space 303 is defined between the platens to receive an exposed but undeveloped copy card 42. When a copy card 42 is in position for developing between the

platens

301 and 302, the movable platen 302 is driven into a sealed engagement against the fixed platen 301 to define a developer chamber 304 formed in the platen surface of the platen 301 and sealed by a ring seal of elastic material 307 which circumscribes the chamber 304. Anhydrous ammonia gas developer is injected under pressure into the chamber 304 through a set of nozzles 305 which are provided in the openings of a conduit 310 formed in the platen 301. The conduit 310 connects to a supply line 311 which is connected to the output 312 of a conventional valve 313 which controls the injection of ammonia developer into the chamber 304. The valve 313 is a two-way valve which has an ex haust port normally connecting the chamber 304 to a The cam 323 is provided with a slight depression 326 at the high lobe thereof to provide a stable position which would prevent movement of the movable platen 302 upon application of pressurized ammonia vapor to the chamber 304. The shaft 324 and cam 323 are driven in rotation by a motor 325 through

gears

327, 328. The gear 327 carries a semi-circular actuating surface 331 which actuates a switch 330, the purpose of which will be described in conjunction with the description of FIG. 7.

Referring again to FIG. 2, the delivery conveyor 19 includes a pair of rollers 340 which include a driven roller 341 and an idler roller 342, each rotatably supported on the

respective shafts

343 and 344 which are supported upon the base plate 11. The roller pair 340 is spaced at the exit end of the developing station 18 at a distance from the roller pair 92 which is less than the length of one of the copy cards 42 so that a copy card at the developer station will always be under the control of one of the roller pairs.

The driven roller 340 is provided with a drive pulley 351 which is driveably engaged by a belt 352 which surrounds an idler roll 353 and a drive pulley 354 rigidly mounted to a shaft 355 of a motor 356.

A limit switch 361 is rigidly supported by the base plate 11 and includes an actuator finger 362 which is positioned so as to be tripped by a card passing through the nip of the rolls 340.

The controls of the copier machine are illustrated in the diagram of FIG. 7. The controls of the machine are designed to function to initiate a copying cycle in response to a start signal. This signal will usually indicate the presence of a master card to be copied at the roller pair 165. This card has usually been presented to these rollers by a document retrieval device. The start signal is indicated diagrammatically as the output of a start signal generator 401 in FIG. 7. This signal is connected to circuitry which starts the drive for the rollers and energizes the motor 190 to turn the rollers and to move a master card in the up direction into the copier. The passage of the card toward the copier is detected by the limit switch 215. The drop out of the limit switch 215 in response to the trailing edge of the master card energizes an electrical delay circuit 402 which generates a delayed electrical signal which is connected through circuitry which turns off the motor and stops the drive to the rollers 165. This delay also energizes the solenoid 206 which trips the limit switch 204 which is connected to energize a delay circuit 403 which generates a delayed electrical signal which energizes the solenoid 231. The solenoid 231 lifts the platen assembly 191 into position which trips a limit switch 230. This signals that the master card is in position ready for copying. The turning on of the limit switch 230 is connected in a circuit to de-energize the solenoid 206.

V The signal from the start generator 401 is also connected in a circuit to turn on the

motors

44 and 87 to .88 which, upon a dropping out of the switch 88 in response to the trailing edge of the card being fed, energizes a delay circuit 406 which generates a delayed electrical signal which turns off the motor 87. This delay is sufficiently long to allow the card to be completely fed into the slot 128 of the clamp assembly housing 243. The delay signal also activates the solenoid 145, which retracts the roller pairs 62 and 91. This trips the limit switch 151, which energizes the clamp motor 261, which operates until turned off by the tripping of the limit switch 274. The limit switch 274 is connected to the input of a delay circuit 408 which generates a delay signal which actuates the solenoid for the shutter timer mechanism 236. This mechanism ineludes a timer 237 which generates a delayed signal which closes or de-energizes the shutter solenoid 236. Typically, the time constant of the timer 237 is in the order of approximately 1% seconds with a conventional ultraviolet source of the mercury vapor type. The output of the timer 237 also energizes a delay circuit4l3 which generates a delayed signal which energizes the clamp motor 261 which opens the clamp and continues operating until the limit switch 273 is tripped, which turns off the motor 261 and also re-energizes the solenoid 145 to return the drive rollers to their positions in engagement with the edges of the copy card. This action energizes the limit switch 152.

The signal from the limit switch 152 is used to initiate the mechanism to discharge the exposed copy card toward the developing station and also may be used to return the master card to storage, or, in the event that plural copies are to be made, to decrement a counter.

The output of the limit switch 152 is connected to turn on the

motors

87 and 122, which-cause the card to be advanced out of the exposure station and through the conveyor 17. This card will trip a limit switch 125 which will de-energize the motor 87, and the trailing edge of the card will cause the switch 125 to drop out, initiating the delay circuit 415 which generates a delayed signal which turns off the motor 122 and turns on the motor 325, which closes the developing chamber. The closure of the developing chamber is sensed by limit switch 330 which, upon actuation, turns off the motor 325 and energizes a delay circuit 417, which generates a delayed signal which energizes the solenoid valve 313 and begins a timer 418 included in the valve 313. The time constant of the timer for developing is approximately five seconds when developer pressures in the area of 75 psi are applied. The output of the timer 418 signalsthe closure of the valve 313 and energizes a delay circuit 419 which generates noise signal to again turn on the motor 325 to open the developing station. This causes the de-activation of the limit switch 330 upon completion and generates a signal to turn off the motor 325. The signal from the limit switch 330 also signals the turning on of the

motors

122 and 356 to remove the card from the developing station. The advancing developed card trips limit switch 361 which is connected in a circuit to turn off the motor 122.

If multiple copies are to be made, the signal from the limit switch 361 passes through an AND-gate 422 and re-initiates the card feed cycle by turning on the

motors

44 and 87.

When a signal is generated either from the limit switch 152, if only single copies are to be made, or from the zerooutput of a counter 424 which would be em'- ployed to determined the number of multiple copies to be made, a signal is generated which is connected to circuitry to the solenoid 231 to de-energize the solenoid 231 and to cause the platen 191 to drop to release the master card. The movement of the platen 191 will cause the opening of the limit switch 230 which will generate a signal through appropriate circuitry which will energize the roller drive and the motor 190 to carry the master card downward and out of the copying device. The downward passage of the master card will trip limit switch 215 which will generate a signal to the delay circuit 402 which will again output a delay signal which will turn off the roller 165 drive and the motor a 190. This signal is prevented from re-activating the sequence beginning with solenoid 206 by virtue of the AND-gate 425 having an input connected to the start signal generator 401.

The operation of the copier described above will be best understood by reference to the sequence of the diagrammatic illustrations represented in FIG. 8A-8Z. Referring to FIG. 8A, a top diagrammatic view of the copier is illustrated while in its normal standby condition. None of the motors nor any of the parts are moving at this time and the clamp assembly 243 and the developer platen 302 are in their retracted positions.

Some of the views of the sequence are top views similar to those of the FIG. 1 and 2, while others are elevational views similar to those of FIGS. 5 and 6.

FIG. 8B is a diagram in elevation through the exposure station 14, illustrating the condition of the apparatus as the start signal is received. At this time, a master card 167 is presented at the rollers 165.

As FIG. 8C shows, the motor 190 is energized to drive the rollers 170 and to move the master card 167 upwardly toward the platen 191. At this point, the master card trips the limit switch 215.

Referring to FIG. 8D, the card 167 has reached its uppermost position, passing a limit switch 215 and releasing it, which, after a time delay, has disengaged the motor to stop the

rollers

180 and 170. At this point, the rolls 165 are also stopped.

Upon the stopping of the motor 190, the solenoid 206 is energized to move the platen 191 to the position shown in FIG. 8B to cause the lip 221 to engage the lower edge of the master card 167. This action trips a limit switch 204 within the solenoid 206 to energize the lift solenoid 231, which lifts the platen 191 and the master card 167 into the viewing aperture, tripping a limit switch 230 and de-energizing the solenoid 206 as shown in FIG. 8F. 0

Simultaneous with the actions illustrated in the above FIGS. 8B-8F, a copy card is fed to the exposure station by the procedure illustrated in FIGS. 8G-8K, described as follows.

FIG. 86 illustrates the copier 10 in top diagrammatic view with the master card 167 in the position that it will attain by the time the copy card has arrived at the exposure station 14.

FIG. 8H illustrates the initiation of the feed of a copy card 42 through the actuation of the motor 44 which advances the feed plate 37 as shown. Also, the motor 87 operates to drive the

rolls

61 and 62 to continue the feed of the card after it has been advanced by the feed plates 37 from the supply magazine 12.

, fed into position within the exposure station 14 and the limit switch 88 is released which, after a specified time delay, has de-energized the motor 87. At this time, and in FIG. 8K, the solenoid 145 is energized to withdraw the

rolls

62 and 91 to release the card 42.

Referring to FIG. 8L which is again a cross sectional elevational diagram through the exposure station, the relative positions of the copy card 42 and the master card 167.are illustrated. Upon the occurrence of the condition illustrated in FIG. 8K above, the master card 167 being brought to the exposure station as was illustrated in FIG. 8F, and the copy card being brought to the exposure station as illustrated in FIG. 8K, the clamp drive motor 261, as illustrated in FIG. SM, is actuated. This moves the clamp 243 toward the'platen 191, and the abutment of the clamp 243 and the aperture wall stop the clamp at this point. However, the motion of the motor 261 and the shaft 244 of the ram force the rubber plate on the plunger within the clamp 243 to urge the copy card 42 and the master 167 into contact. At this point (FIG. 8N), the limit switch 274 is tripped and the shutter of the light source 16 is opened to expose the copy 42. Upon completion of the exposure time interval, the motor 261 is re-energized and the ram 243 is withdrawn to its initial position (FIG. 80), at which point the limit switch 273 is actuated to de-energize the motor 261.

' Referring again to the top elevational views of FIGS. 8P-8W, upon the stopping of the motor 261, the solenoid 145 is re-energized and the

roller

62 and 91 are again dropped into the engaging position with the copy card 42 as shown specifically in FIG. 8?.

When this has occurred, as is shown in FIG. 8A, the

motors

87 and 122 are energized and the copy card 42 is fed through the advancing conveyor 17 toward the develop station. Upon advancement of the card 42, the limit switch 125 is tripped. This action turns off the motor 87 FIG. 8R illustrates the copy card 42 moved to the develop station 18, the limit switch 125 having been released and stopping the motor 122 after a specified time delay.

After this time delay, as is illustrated in FIG. 8S, the

motor 325 is energized to drive the platen 302 into closing position for the developing station 18. The card 42 is at this point sealed withinthe develop station 18. Referring to FIG. 8T, upon movement of the platen 302 to its fully closed position, the motor 325 is stopped, and the injection of high pressure ammonia developer into the development chamber is initiated by the opening of a valve 313.

As shown in FIG. 8U, at the specified time delay, the valve 313 is closed and the motor 325 is re-energized,

moving the platen 302 away from the development station 18.

Referring to FIG. 8V, upon the flow outward motion of the platen 302, the motor 325 is stopped and the motors 122 356 are energized, forcing the card 42 from the development station, at which point the limit switch 361 is tripped.

Referring to FIG. 8W, the passage of the card 42 into the hopper 20 releases the limit switch 361 and stops the

motors

356 and 122.

At any time after the position illustrated in FIG. 8? above is attained, provided no additional copies of the I same master are to be made, the following operations illustrated in FIGS. 8X through 8Z may be executed to return the master card to its file.

Referring to FIG. 8X, the solenoid 231 is de-energized and the platen 191 is allowed to drop down and away to allow the master 167 to drop into engagement with the rollers 180.

As shown in FIG. 8Y, the motor 190 is then energized in a direction opposite that of FIG. 8C above so as to drive the

rollers

180 and 170 to move the master card in a downward direction.

At this time, the rollers are also driven at the same direction and the master card 167 is delivered from the exposure station 14 in the manner illustrated in FIG. 8Z.
