The invention relates to copier machines, and more particularly to one Copy machine system in which a large number of attachments are attached to a single copy machine to enable the copier to operate in different modes.

There are many different types of copier machines currently on the market. Each of these machines is generally capable of only one mode of operation. For example, there are machines which are able to produce copies only of sheet material (letters, etc.). Such machines cannot produce copies of a book page, for example, because the document to be copied typically has to be moved through the machine and the transport system for the original cannot accommodate a book or any other spatial object.

Other machines are able to add a book page copy. A book can be placed on top of a stationary scanning window, with the page to be copied is scanned by a movable optical system, or the book can be placed on a glass plate which is attached to is moved past a stationary optical system. Book copiers are also able to print sheet documents or Copy staple documents (a sheet of paper or staple document can be thought of as a very thin book). One third type of machine is that of hikrofilmoriginal en makes paper copies. An overview of the machines currently on the market leads to the result, that each machine is generally only able to work in a single operating mode, e.g. as a letter copier, as a book copier or as a microfilm copier.

The illustrated embodiment of the invention includes one Copying machine, which is equipped with a large number of rollers at the top of the machine, which are driven by an original drive chain can be rotated in both directions in the machine. The machine includes one Electric circuit for controlling the energy supply of the lighting lamps, the operation of a knife, to copy sheets cutting off a roll of copy paper, switching the Direction of movement of the rollers on the top of the machine, etc. The electrical circuit is not completely. Various points in the circuit end at plugs in an electrical connector, which is at the top of the machine is appropriate.

The letter copier attachment consists of a bridge which is placed on top of the machine. The bridge comprises another Set of matching rollers which are driven by the rollers in the copier. The roller pairs transport together an original document between the top of the machine

10984S / 1336

and the bottom of the bridge. The document is moved back and forth when it is necessary to make multiple copies of the same original. The bridge includes a link, which fits into the connection of the machine. The bridge connection is used to connect the electrical circuit to the copier complete so that the machine works in letter copy mode. The bridge also surrounds a large number of photocells, which are supplied with energy by excitation lamps on the top of the copier. Determine the photocells the position of the original document below the bridge. The thotocells are contained in the electrical bridge circuit, which is coupled to the machine circuit and the photocell outputs control the machine to produce a roll of copy paper cut at appropriate times to reverse the direction of movement of the machine rollers, etc.

A second additional device, the so-called "book copier" accessory, comprises a glass plate which is placed on top of the machine. The glass plate is moved forward and back by the machine rollers moved back so that a book placed on the glass plate back to a scanning window arranged on top of the machine. and is moved. The book copier attachment includes a cam which can be adjusted to match the length of the to the original page to be copied. A row of microswitches is provided on the top of the copier, and when the glass plate is moved back and forth by the machine rollers, the cam operates the microswitches to synchronize the operation of the machine with the position of the plate. The book copier accessory includes an electrical one Terminal which mates with the machine terminal, thereby the electrical circuit of the machine in the manner modify it to work in book copy mode.

109845/1336

Furthermore, a mechanical modification is also carried out in the basic machine when the book copier is attached to it. The glass plate has a certain thickness which would otherwise enlarge the optical path of the light which is reflected from the original to be copied and transmitted to the exposure station, where it strikes the head sheet. If the optical path of the base machine is designed to properly focus the light reflected from the original document (on top of the machine) onto the copy sheet, the optical path lengthened by the thickness of the glass plate would result in poor focusing of that of a book (or a Original document) of reflected light, which is placed on the glass plate. For this reason, when the book copier attachment is applied to the machine, a lever is moved which in turn changes the position of a mirror inside the copier machine. The change in position of the mirror

serves to shorten the optical light path within the machine. The total length of the optical path that consists of the increase caused by the glass plate and the decrease caused by the rearrangement of the mirror, provides perfect focus.

The book copier attachment includes a pair of rails which extend outside the machine. The rails are required to support and guide the glass plate as it is moved back and forth by the machine rollers. the Rails necessarily increase the size of the overall machine. However, the fastening of the rails and the Glass plate on the machine as well as its removal can be done in less than a minute.

109846713-36

According to one feature of the invention there is provided a copier machine which comprises an electrical circuit connected at a number of points in an electrical connection ends, whereby the machine can operate in different modes depending on particular additions which on the machine., with each addition a suitable electrical connection to complete the Has overall circuit of the machine in various ways.

According to a further feature of the invention, a drive device on an exposed surface of the copier machine, which is connected to any of the various attachments attached to the machine are engaged to thereby limit the movement of the various elements in the attachment to control, in synchronization with the operation of the copier.

The copy paper used in the machine is more electrophotographic Art. It has the ability to hold an electrical charge which is generated by an electrostatic field its photoconductive layer is applied. The layer can be discharged by exposure to light. Typically there is the copy paper roll 33 of Fig. 1 made of a base paper, in which photoconductive zinc oxide particles in a resin layer are distributed. There is an electrical charge on both the front and the back of the zinc oxide layer upset. When light hits the zinc oxide particles, they become conductive and the charged surfaces are neutralized.

When the leading edge of the copy paper roll 33 is fed through the rollers 35, 36, 39, 40 and 41, 42, the paper passes through the corona shield 43, 44, in which two sets of (not shown) very thin wire elements are arranged on which a high DC voltage supply is applied. The negative wire elements are contained within shield 44,

1098A5 / 1336

2119097

while the positive wire elements are arranged within the shield 43. The shields support the structure of the corona field.

When the copy paper passes through the two sets of oppositely charged wire elements, one becomes uniform negative charge is applied to the photoconductive layer on the surface, which is used for shielding 44 shows. A uniform positive charge is applied to the surface of the layer which is used for shielding 43 shows. The charges applied to the surfaces of the copy paper are held for a reasonable period of time, provided that the surfaces are not exposed to light. When light hits the photoconductive layer, the Zinc oxide particles exposed to light are conductive, so that the negative and positive charges in those exposed to light Areas are neutralized.

When the copy paper on the printing element 23 and the exposure window passes, which consists of a monofilament covered glassless window 64, becomes the photoconductive Layer according to the dark and light areas on the too copying original exposed. The rotary knife 38 cuts one sheet from the roll so that the cut sheet is the same length as the original to be copied. If that Knife 38 works, stops the copy roll paper feed, although the cut copy sheet is moving at the exposure window continues past, namely to trough 47 in the development station of the machine *

The original document 12 is printed on rollers 9 and 16 in The machine was introduced, which turned in such a way that the original was moved in the illustrated film (from the right side of the machine shown in FIG. 3? 1

109846/1336

while the original is at the scanning window above As the glass plate 22 is passed, light from two exposure lamps (shown in phantom in FIG. 1) is inside of the reflector 25 from the bright image areas on the original along the dashed arrows 27 as shown reflected. The light passes through lens system 28, assembly 30 and window 64 to expose the copy paper. The copy paper feed is controlled so that the leading edge of the copy paper within the exposure window in optical synchronization with the leading edge of the original is within the sampling window. The copy paper holds the negative charge in those areas which are the dark (Picture) areas correspond to the original. The areas of the original that do not belong to the picture reflect a large one Part of the light on the surface of the copy paper, causing the neutralization of the charged areas, which correspond to the areas on the original that do not belong to the image.

The copy paper is then fed to the tray 47. In the drawn In the illustration, the front end of the copy paper has just reached the trough. The copy paper continues on its way 46 until the copy sheet is ejected from the machine. In the trough 47 there is a developer solution which consists of charged toner particles which are attracted to the negatively charged image areas on the copy paper. The attracted toner particles are impregnated and fixed on the copy paper layer by a system of pressure rollers as well as an embossed hot air drying.

When the original document 12 is inserted between the pick-up rollers 9 », the original is in the tfig. 1 moved to the left. When the leading edge of the original comes off rollers 9 »16

109846/1336

appears, it presses the photocell switch 13. Everyone the photo cell switch 13 »14 ·» 15 has a corresponding Light source 21, 20, 19 equipped. When the leading edge of the original between a light source and its corresponding photocell switch passes through, this change of state is registered and used for control used in machine operation. When the switch 13 operates first, the copy paper roller clutch becomes K-12 (see Fig. 2) is energized to cause the copy paper feed rollers 35 »36 to rotate. These Rollers pull the leading edge of the copy roller to feed the copy paper through the corona unit. The remaining Rollers located along the copy paper path operate continuously. First is the leading edge of the Copy paper in the area of sheet 37 and knife 38. As soon as the rollers 35 »36 begin to rotate, copy paper becomes pulled from the roll into the copy paper i transport system. The corona unit within the shields 43, 44- charges the surfaces of the copy paper. The original and the copy paper are synchronized in their movements. The distance along the copy paper path from the knife to the intersection of the optical axis with the exposure window is equal to the distance from the photocell switch 13 to the intersection of the optical axis with the scanning window. Because the rollers along the original and the copy path the original and the copy paper move at the same speed and there the movement of the copy paper past the knife under the control of the rollers 35 »36 takes place at the moment when the leading edge of the original is just at the photocell switch 13, it can be seen that the original and the copy paper with each other during of the scanning process are in optical synchronization.

109845/1336

When the trailing edge of the original passes the photocell switch 13, the copy paper roller clutch £ -12 is released. The movement of the rollers 35 »36 is stopped and the copy roller 33 remains stationary. At the same time, a Knife spool (not shown in Figures 1 and 2) is energized to cause rotary knife 38 to cut the copy paper to exactly the same length as the original. The cut sheet is advanced through the developer tray 47 by the copy paper transport system. The amplifier drum 48 is constantly moved in the direction shown. (It is also possible to do them in opposite directions and with different speeds.) This ensures that the copy paper moves through the developer tray will. The developer liquid itself is contained in the tank 57, which is drawn out of the machine by the lever 58 can be. A pump system (not shown) pumps the developer up into the trough 47.

The copy sheet is then under the baffle 56 to the Nip of the pressure rollers 53 »54 out. The pressure rollers remove the excess liquid from the copy paper, and In this way, the attracted toner particles are also to a small extent into the zinc oxide layer surface of the copy paper embedded. The wiper 52 wipes the metal pressure roller 53 »to" retract "or trigger one To prevent the previous image, just like the wiper 51 wipes the intensifying drum 48. The copy sheet is then guided by the circulating air under the drying lamp 59 onto the belt 61, which it continuously around the rollers 62, 63, the roller 62 being moved by the constantly rotating chain drive. The copy sheet is finally passed between the belt 61 and the guide rollers 55, different ones of which can be arranged on the same shaft. These rollers offer

109845/1336

the copy paper slightly so that it is on the (not stacks properly.

Blowers 23, 24 convey air (shown by arrows 26) through the machine, as is known per se, for example is to dissipate the heat generated by the lighting lamps. A number of guide devices 32 are provided, to guide the air in a suitable manner.

A shutter 31 can be moved up and down from the outside (not shown). The deeper the right end of the shutter is, the larger the opening and the stronger the exposure. The units symbolically represented in FIG. 1 correspond to known embodiments, and these do not need to be explained in detail in order to understand the invention.

In the case of multiple copying, the original is saved in the first cycle in scanned in the usual way. Before it was moved far enough to get out of the last set of reels 7 »18, pressed the rear edge of the original the photocell switch 15 · This causes the original transport roller system to switch and returns the original at a speed greater than the forward speed, so that the Original is moved to the right into the normal feed position. When the leading edge of the original has hit the photocell 14 releases, the original transport roller system is ■ normalizes and transports the original to the left past the scanning window, where it is scanned a second time. (Any references to the leading and trailing edges of the original used herein refer to the left edge of the Original and the right edge of the original in the 3? based. Thus, even if the original is transported in the reverse direction, that in the

109845/1336

■ Fig. 1 edge furthest to the left referred to as the leading edge.) This process is repeated until the multiple copy selection switch 107 has counted to zero and itself then, in the normal single copy position. The selector switch is advanced by one unit for each copy made by the facility. If all copies except the last are made, the selector switch is fully set to the single copy operating position while the Machine makes another copy and then puts the original on the original receiving table.

The cam 16 comes with the original forward feed system coupled when the leading edge of the original passes the photocell switch 15. The cam rotates against the Clockwise as the original continues to move forward. When the original begins to move in the opposite direction To move direction, the cam 106 begins to return clockwise to its original position. The cam has its The starting position is completely reached again when the front edge of the original on the photocell 15 in the opposite direction passes by. However, while the cam 106 is moving clockwise, there will be some time before it returns to the starting position of the switch SW-Q is actuated. Pressing this switch turns on the copy paper feed. The leading edge However, the original must still pass the photocell 15 (The switch SW-Q is operated while the front edge of the original is still to the left of the photocell 15 in the IPig. 1) and also past the scanning window to the photocell 14. The leading edge of the copy paper must run from the knife to the front end of the exposure window during the same time interval. The original feed rate in the reverse direction is greater than the copy feed rate. In order to properly register the original and of the copy within the scanning and exposure windows

109345/1338

2119897

ensure, it is only necessary that the cam 106 actuates switch SV-Q at a point during the reverse movement of the original at which the ratio the distance of the "leading edge of the original from the photocell 14 to the distance between the knife and the point im Copy sheet path of movement, at which the copy sheet is synchronized with the movement of the original, same as that Ratio of the original reverse feed rate to the copy feed rate is. In this way, the leading edge of the original reaches the photocell 14 just when the leading edge of the copy sheet reaches the exposure window.

When the main drive motor 72 in FIG. 2 is energized by the system on-off switch (not shown), it causes the main drive rollers 71 to rotate in a counterclockwise direction. The main drive chain 7 ^ is driven in a counterclockwise direction by the drive rollers "] Λ . This chain moves various gears including the tension adjustment gear 123 and the gears coupled to the rollers 42, 50, 53" and 62 "These four rollers rotate continuously to drive the copy paper. The fifth roller, which rotates continuously in the path of the copy paper, is roller 40, which is coupled to a gearwheel that is driven by drive chain 73. The chain 73 as well as the chain 74- is driven by gears 71 as long as the main power switch is supplied with energy. The chain 74 drives the sprocket counterclockwise and drives the sprocket 76 clockwise. Gear 76 rotates faster than gear 79 because it is smaller in diameter.

109845/1336

- Ip -

The chain 75 is the original drive chain. It is driven indirectly by the main drive chain 74 via an electrical clutch system. When the forward clutch K-9 is engaged, the gears 78 and 79 are coupled together and the gear 78 moves continuously while the gear 79 is rotated. The drive chain 75 moves in the forward direction "(F), and since the diameter of the gears 78 and 79 are the same, the chain 75 moves at the same speed as the chain 74- ^D a trolleys that have the same diameter move Original and copy sheet through the machine at the same speed. The chain 75 not only moves via a tension adjusting gear 111, but also drives the three gears which are coupled to the rollers 16, 17 and. As shown in FIG these are the three rollers driven in the original transport system.

During the multiple copying, the original is first moved in a forward direction to be scanned and is then moved backwards at high speed. This process of moving forwards and backwards is long continued as the machine remains in multi-copy mode. When the original is moved backward, the forward clutch K-9 is released and the gear 78 is no longer coupled to gear 79. At the same time, the reverse clutch K-7 is operated, which the reverse gear 77 with the Brings gear 76 into engagement. Since the gear 76 with moves at a faster rate than gear 79 and gear 77 when coupled to gear 76 with whose speed is running, the chain 75 moves in the reverse direction (R) at a faster speed than when going in the forward direction runs. When the chain 75 is moved clockwise, the rollers 16, 17 and 18 move in the reverse direction.

109845/1336

direction (opposite to the direction shown in Fig. 1), to return the leading edge of the original to the front of the scanning window. When this point is reached the control circuits switch the drive direction of the chain '75 again by disengaging the reverse clutch K-8 and the forward clutch K-9 is engaged.

Although the chain 73 continuously drives the gear wheel coupled to the roller 40, as do the three following ones and ends in the transmission 80, the roller 35 runs however not continuous »This is the roller that feeds the copy paper starts. Only if the clutch K-12 is actuated, the roller 35 is coupled to the gear 80. At this time, the copy paper starts to be fed.

In the original transport system, rollers 16, 9 are used as original input rollers, rollers 17, 8 are used as scanning input rollers and rollers 18, 7 are used as original output rollers. According to the description above, rollers 16, 17 and 18 are driven by chain 75 in both directions driven. The rollers 7 »8 and 9 are included in the bridge assembly 11 and are in frictional contact with their respective lower rollers when the bridge 11 is placed on the machine. The bridge can be removed in such a way that a possible fault in the original can be corrected with little difficulty. _{The photocell switches 13 9} 14 and 15 contained in the bridge 11 are connected to the rest of the machine by contacts on the bridge 11. The bridge also has a pressure plate (not shown) for pressing on the scanning glass 22 against the original. The distance between the printing plate and the scanning glass 22 ages some paper thicknesses.

109845/1336

Fig. 3 schematically illustrates the control circuit of the copying machine, which comprises the various elements shown in FIG. 1, but without the bridge 11. How As described below, any of the various attachments can be mounted on top of the copier will. As will also be described in detail below, the top of the copier has three rollers 16, 17 » (see FIG. 1), a scanning window 22 and three excitation lamps 19, 20 and 21. There is also a at the top of the copier electrical connection provided, which has a number of plug contacts, which with different points in the Circuit of Fig. 3 are connected. The various circles shown in Fig. 3 represent the plugs, where the number or letter in each circle means the number or letter of the connector. The plugs are characterized by the numbers 1 to 15 "and the letters A-H, J-L, N, P and S. (The connector G and the reserve connector called "extra connector" ("extira pin") are not connected.

It is difficult to understand the operation of the overall circuit in any of the three modes with reference to FIG to understand FIG. 3. Although the electrical circuit is ever more the three additional arrangements as well as the plug connections in each of the additional devices are shown in separate figures are, the operation of the machine in a special operating mode is much easier to understand if In a new representation the circuit is drawn as it arises when each of the three additional devices is on the machine is arranged. This redesign of the circuits is explained below. Furthermore, for the sake of simplicity of the facts in the hay representations omitted all those elements which in the casual mode of operation are not in function. For example, although the switching

109845/1336

ter S1A, S1B, S2A, S3A and SQ1 on the top of the machine arranged, however, these switches are only copied by the book are closed and are therefore not included in system operation in letter copy mode. This is why these are Switch not shown in the key representation of the circuit for this operating mode. .

As a further example, consider the connector E in FIG. 3 pointed out. This connector is with the positive potential rail 115 connected. According to the representation in Fig. 13 » which are the electrical connections within the letter copier bridge (as will be described more fully below), the letter copier bridge includes a control panel which contains the Connects connectors E and F on the copier machine. From Fig. 3, however, it can be seen that the connector F with both switch SQ1 and switch SW-D connected is. Thus, in the letter copying mode, the positive potential rail 115 is connected to the two switches. Of the Switch SQ1 is located on the top of the machine and is only closed by the book copier plate. Consequently the switch SQ1 is not closed in the letter copying mode, and there is therefore no need to switch it on in the new display the circuit in FIG. 14 for the letter copier mode, since the potential at connector F on the copier machine cannot be routed to any other point in the circuit via switch SQ1. The switch SW-D in the However, the copier (see Fig. 4-) will shut down if multiple copies are made of any original (Letter, book or microfilm) as described below. When the switch SW-D is closed, it connects the Plug F with plug 0. From the illustration in Fig. 13 it can be seen that in letter copying mode the control panel is in the bridge connects connector 0 with connector D. From the

109845/1336

Representation in Fig. 3 can be seen that the plug D is connected to the excitation windings of the relays K4 and K5, which work when multiple copies of a letter are made. Consequently, the redesign of the Circuit for the letter copying mode the switch SW-D.

The full wave rectifier 93 transfers a 90 volt potential conductors 113 and 114, with conductor 113 in relation to conductor 114 is positive. The potential on these two conductors controls the operation of the various clutches and timing motors. There is no need to use the potential to be developed even if no additional device is attached to the machine. For this reason, a lock is provided, in order to prevent the supply of energy to the full-wave rectifier when no additional device is attached to the machine is. The line L1 is led directly to one of the input terminals of the rectifier. The other input terminal of the rectifier is connected to connector L. If no additional device is attached to the machine, the plug L is floating and it is connected via the conductors 113 and 114 no potential developed. However, if one of the additional devices is attached to the machine, the connector L connected to plug K in the additional device. The connector K is in turn connected to the on-off switch SW-P L2 connected. Thus, only if one of the additional devices is placed on the machine that is required to operate the various time motors and clutches Potential developed in the machine.

The power supply 94 is used to provide a 26 volt potential to develop the "" pus 115 and 1 .6, the conductor 115 with respect to conductor 116 is positive. This potential is used to operate the various existing in the machine

109845/1336

Relay. The power supply has two inputs. The one is directly connected to the line L1. The other is with connected to plug L, which can be connected to plug K (and to line 1 * 2), but only via one of the Additional equipment. The power supply is also polar only in operation if one of the additional devices is attached to the machine · The energy supply is direct with photocell excitation lamps 19 »20 and 21 connected.

In the circuit of the Pig. 14, which is the operational parts of Circuit in letter copying mode, the photocell detectors are simply represented by boxes SVPI, SW2, SW3. For this reason, it is necessary to understand how each of the switch boxes actually works. According to the illustration in the Pig. 13 is one end of the photocell 13, which is present in the letter copier bridge, through the control panel in the letter copier bridge is connected to connector 6 in the machine, while the other end of the photocell is connected to the plug 7. From the Pig. 3 it can be seen that one end of the photocell via resistor R13 is connected to the base of the transistor Q1, while the other end of the photocell is connected directly to the emitter of the ! Transistor Q1 is connected. The photocell works as a a source with variable potential »If it is illuminated, there is a voltage drop across the photocell, and the! transistor Q1 does not conduct · The heater K1, which is over the normally closed contacts K4-B is connected to the collector of transistor Q1, so it is not energized State held «On the other hand, if the photocell is not hit by Lieht, the base of the Transistor Q1 positive with respect to the emitter, it flows Current through the coil circuit of the transistor, and the relay AI is activated.

109845/1336

The positive potential of the rail 115 is fed via the level adjustment potentiometer R1 iind the resistors R4, R1Q to the base of the transistor Q1. The emitter of transistor Q1 is connected directly to negative rail 116. The resistances have such values that, without a potential contribution from the photocell 13, the voltage drop across the base-emitter connection of the transistor Q1 is sufficient to bring about the conduction in the transistor and thus the actuation of the relay K1. The photocell 13 is, however, connected via the base-snitter connection so that the voltage drop developed across the photocell counter-biases the base-emitter connection, ie the negative terminal of the photocell is connected to the base of transistor Q1. As long as the photocell registers light from the lamp 21, the transistor Q1 remains off and the relay K1 remains without energy. Only when an original document to be copied passes between the lamp and the photocell, the photocell does not develop any potential and the transistor Q1 conducts, with the relay K1 being actuated. This company is in the IFig. 1-4, where the entire lamp and photocell circuit is simply shown as a switch SW1 which is normally open. Only when an original document to be copied passes between the lamp 21 and the photocell 13 does the switch SW1 close, and current flows through the switch and the contacts K4-B to the winding of the relay K1. A similar circuit is available for relays K2 and K3. As shown in Pig. 13, the negative terminal of the photocell 14 is connected to the plug 8 and the positive terminal to the plug 10. According to Pig. 3, the connector 10 is connected to the negative rail 116 and the connector 8 is connected to the base of the transistor Q2 via the resistor R14. An identical circuit is provided for the photoelectric cell and the transistor Q3.

On the front of the machine there are two brackets 138 (see FIG. 2) which are used to hold the book copier attachment and the microfilm reader attachment are required. The three reels 16, 17 and 18 are on top of the Machine arranged, and one of the excitation lamps 19 »20 and 21 is arranged in the region of each roller. The reels will driven by the drive chain 75, the guide drive 141 is also shown in the drawing. The scanning window 137 is arranged between the rollers / TH, which is typically a glass plate. On each side A plug 131 is arranged on the scanning window. A A pair of plugs is required to lock the letter bridge in place on the top of the machine.

An electrical connection ir-t on one side of the scanning window 132 provided. This connector has a number of plugs which mate with various parts of the control circuit connected to the copier. Each accessory device includes a similar connector, and if connector 132 is connected to one of the connections of an additional device, then the resulting control circuit is for this special additional device specially designed.

An upstanding rail 156 (see FIG. 20) is on top of one Side of the machine. This rail includes a groove 156a to guide one side of the book copier plate which is on the machine is set up. A spring 133 is arranged at the end of the rail (see FIG. 8), which is rotatable at 134 is appropriate. A pin 142 extends upward from the rear of the rail. If the spring is the one shown In position, the pin 142 extends through a bore in the spring, and the spring blocks the rearward movement the plate, i.e. it determines the maximum rearward position of the plate when the plate is on the machine

10984S / 1336

_s is mounted it is inserted from the rear (right side of Figure 8). To place the plate on the machine, the spring 133 is raised slightly so that it releases the pin 142 and is then rotated clockwise as shown in FIG. The plate is then inserted into the two corresponding grooves in the rails 135 and 136 on either side of the machine, and when it is pushed all the way forward on the machine, the spring 133 is brought into the blocking position shown in FIG.

The top rail 135 in Figure 8 is the rail 156 therein similar in that it has a groove to guide one side of the plate. However, rail 135 still includes four switches S3A, S2A, S1B and SQ1 as well as a start button S1A.

The letter copier attachment is placed on the machine in FIG shown. The accessory includes a bridge section 205, a glass plate 209 and a lid portion 210. When the copier is used in letter mode, an additional metal plate 201 is used as shown 9 and 10 placed on the machine. The plate includes a short vertical section 201a, and two downwardly facing pins 203. The pins are in slots used at the top of the machine. The plate 201 is moved from side to side, which is the width of the original to be copied. The original, for example the original 204 shown in FIGS. 9 and 10, is placed on the plate 201 so that one edge is adjacent to the vertical portion 201a. The plate 201 is like this arranged that the original is centered on the bridge.

On both sides of the bridge 205 there is a slot 207 in which a slide lever 206 is attached. According to the illustration in Fig. 12 is ^ each slide lever 206 with equipped with a pin 230. A locking element 2JJ is rotatably mounted on each side of the bridge as shown at 232! and the pin 230 is in a Slot 231 inserted in the locking element. If the Slide lever 206 is moved to the left in FIG. 12, it is evident that the element 233 is counterclockwise rotates so that the element hits the pin 131 on the machine released t. To lock the bridge in place » the two sliding levers 206 are moved to the left in FIG. 12, the bridge is brought into its correct position, and the two slide levers are then moved to the right. This turns the two locking elements 233 clockwise moves and thus grips the pin 131.

The letter bridge comprises three rollers 220, 221, 222, which with the rollers 16, 1? and 18 engage on top of the machine. Lifting each roller in the letter bridge is a photocell 13 "^ 4-, 15, as can best be seen in FIG. 11 ₉ which represents the underside of the letter bridge" connected, in the middle of the bridge element 2OJ? a bracket 215 is provided through which a plurality of pins 216 extend. The pins are attached to the plate 217 which lies against the scanning window I37 of the machine. The purpose of the plate is to press the original document to be copied flat against the scanning window so that proper focusing is achieved.

109845/1336

An original document inserted into the letter bridge becomes inserted between the rollers 16, 222 into the gap, as can best be seen from FIG. The original document is then under the plate 225 at the bottom of the letter copier attachment and then passes between the plate 217 and the scanning window 137 · ^ i e three Rollers in the letter bridge are in contact with the rollers on top of the copier. This is done using feathers 234 reached on each side of the roll shafts, as on is shown most clearly in FIG. The ends of the roller shafts or the roller shafts are in corresponding Bushings placed in brackets 240 which allow slight vertical movement. The forces of the springs tension them Rollers in the letter bridge against the corresponding rollers on the top of the copier in each case.

A connection 212 is directed downward from one side of the bridge section 205. This connection is in one Terminal 132 inserted and completed on the machine the control circuit of Fig. 3ι so that the letter copying mode arises. The circuit of the connection 212 is shown in FIG. 13. If the connection with the Terminal 132 engaged on top of the copier is, the circuit shown in Fig. 3 within the copying machine is completed and becomes the circuit shown in FIG.

In Fig. 14 three switches SVM, SW2 and SW3 are shown, which for the three photocells 13, 14 and 15 and the amplifiers assigned to them in the original transport system are represented symbolically. SW1 corresponds to photocell 13, SW2 corresponds to photocell 14, and SW3 corresponds to photocell 15 «Every switch is normal-

wise open, but will be closed when the original passes under the corresponding photocell and the light from the corresponding light source 19, 20 and 21 blocked.

Before further describing the operation of the machine it is necessary to understand the meaning of the various in the Drawing used to explain reference numerals. In FIG. 14 there are six relays K1 to K6. Each of these Relay is usually without power. Each relay has one Number of contact pairs A, B, etc. For example, the Contacts K2 ~ D the fourth. movable contact pair on the Relay K2. All contact pairs are shown in their normal position, with all six relays de-energized. In the event of of the transmission contacts, both pairs are labeled the same, e.g. K3-A with the normally closed connection, which is shown in the usual manner, by a short line that goes at an angle through the Contact icon is drawn.

In Fig. 14 five clutches K-7, K-8, K-9, K-11 and K-12 are also shown. The clutch K-12 is a paper roller clutch, which in the deenergized state causes the paper rollers 35 and 36 to operate. According to the illustration in Fig. 2, clutch K-12 controls the rotation of the roller 35 The clutch K-9 controls the forward feeding of the original, and when it is without energy, it causes the rollers 16, 1? and 18 in those shown in FIG Rotate directions. The clutch K-7 is the reverse clutch, which in the enrgiellos state the backward movement of the original controls. As can be seen from FIG. 14, the transmission contacts K4-A control the energy supply for the two Clutches K-7 or K »9 · The clutch K-8 controls when it is activated State the movement of the cam 104 of Fig. 6 in

10984S / 1336

synchronous running with the original drive chain 75 (see Fig. 2). This clutch is only operated during multiple copying. When the time clutch K31 is operated, it couples the chain drive 126 (through a reduction gear) with the cam 96 (see Fig. 4).

K-10 is the solenoid which, when actuated, is the rotary knife 38 operated to cut the copy paper. At the end of the knife stroke the switch SW-X is opened, when the knife is triggered, the switch is closed again *

In FIG. 14 there are also two time motors TMI and £ M2 shown. When switched on, these motors control the movements of the corresponding cams 95 (see Fig. 4) and 102 and 103 (which contain selection disks 107-5). Both these cams and the cam 104 (see Fig. 6) operate various switches SW-A, SW-B, etc. Each switch has two terminals. When the cams are in their normal positions, as shown in FIG 1-6, some of the switches are open and some are closed. The switch SW-H is, for example closed, and as shown in Fig. 14 is a connection across the two terminals of this switch for winding the relay K1. Others of the switches, such as SW-E, are open. As described below the rotations of the various cams control the opening and closing of the normally closed switches the normally open switch.

The circuit of FIG. 14 is shown in three parts. The various couplings are via 90 VoIt DC voltage rails 113 and 114 connected. The various relays are via 115 "and 26 volt DC rails 116 connected. The corona and the two time motors are connected via the AC voltage line. The knife solenoid is connected across line L2 and negative rail 114.

If the relay XA- is not energized, they are normally Closed contacts K4-A closed, the forward clutch K * -9 is activated, the drive chain 7 $ (see Pig. 2) moves in forward direction, and one in the machine inserted original document is advanced.

When the front edge of the original document actuates switch SW1, the excitation hold for relay K1 is over completes the normally closed switch SW-Q and the switch SW1. The normally closed ones Contacts K4 ~ B form a lift to switch SW-Q, and a part of the excitation current for the relay K1 flows about these contacts. When the relay K1 is energized, the copy paper roller clutch K-12 is actuated, and it flows Current through the winding of the coupling and the now closed, however normally open contacts K1-B. The corona charging system, which is also a high-voltage energy source has (which is symbolically represented by the reference number), is also over the now closed Contacts K1-0 energized, these contacts connecting the corona charging circuit to the ski emme Ii2 line.

At the same time the time motor 5DM1 starts to run, namely when closing the contacts KI-A. The motor circuit is from the terminal L1 via the contacts Ki-A and the normally closed switch SW-B, which is connected to the line terminal L2. Though to the switch. SW-B through the normally closed contacts K1-C and contacts K5 ~ G and K2-A are shunted no current flows through these contacts because contacts K1-Ö are open when relay K1 is energized. The operation of the motor ÜM1 triggers the rotation of the cam in FIG. 4. The cam rotates counterclockwise

10984S / 1338

sense, and as soon as the projections 95a, 95b move a little, the switches SW-E and SW-F close. Each of these switches is connected in the excitation circuit to one of the two exposure lamps (see FIG. 14). In the illustrated embodiment of the invention, two such lamps are included in yeast deflector 25 (see Figure 1). The motor 2! M1 and the cam 95 are provided to ensure that the exposure lamps remain on for a period of at least 5 seconds. This is necessary because the lamps have a tendency to darken when the switch-on sequence is slower. As will be seen below, the cam 95 rotates 120 ° during a copy cycle. If the time motor TM1 is not interrupted, the cam rotates by this amount in a time of 5 seconds. In the case of leach originals, however, the time motor is interrupted, "so that the lamps nn there are energized longer.

As soon as the projection 95c moves a little, the switch SW-A closes, so that the excitation circuit for the time motor TM1 one Forms shunt for contacts K1-A. Thus, even then, when the relay K1 trips, the time motor will still work. The motor continues to run until the protrusion 95b hits the switch SW-B opens. If the relays K1 and K2 do not drop out at this point in time and the contacts Ki-O and K2 ~ A are closed the excitation circuit for © 11 is interrupted.

When the contacts K1-B close, the timing clutch K-11 actuated. The cam 96 begins to rotate counterclockwise (driven by the chain 75) and guaranteed a cut copy length of not less than 20 cm (8 inches).

103845/1336

When the contacts K1-D are closed, current flows through them and through the diode CH12, as well as through the normally closed Switch SW-X and via the winding of relay K6. The relay is energized and the contacts K6-B in the knife solenoid circuit conclude. However, the solenoid is not energized because the normally closed contacts K1-B 2u are open at this time. When the heater K6 is activated, contacts K6-A close to shunt contacts K1-D and in this way the relay as well then keep energized after relay K1 has dropped out.

The relay K1 remains energized until the rear edge of the Originals releases switch SW1 (assuming switch SW-H is open at this time). Usually Opened contacts K1-B return to those in the Pig. 14 · shown Position backwards, the clutch K-12 releases, the rollers 35 »36 stop, and no more copy paper comes out of the Roll 33 fed. Similarly, closing the normally closed contacts K1-B completes the Excitation circuit for the knife solenoid K-10. (The excitation current is one rectified by a half-way rectifier Signal from the knife solenoid via the AC voltage line L2 and the DC voltage rail 114 is connected.) The rotary knife 38 rotates counterclockwise (see Fig. 1), and the copy sheet is cut from the copy paper roll. At the end of the knife stroke the switch opens SW-X and the relay K6 drops out. The contacts K6-B open, the solenoid K-10 drops out, and the knife returns to its starting position return. Although the switch SW-X closes again, the relay K6 is not energized again because at this time both contacts K1-D and K6-A are open. The diode 0R10 is provided in parallel to the knife solenoid in order to prevent the to suppress large switching surge, which would otherwise occur when the contacts K6-B open.

The dropping out of the relay K1 thus controls both the stopping the paper roll feeding as well as the operation of the knife. This could be a problem if the feeder stops before the knife works (the copy paper transport system would continue to pull copy paper "while none could be fed through rollers 35 and 36" if the following Corrective measures would not have been taken »If the leading edge of the copy paper was first moved over the rotary knife 38 is guided, it continues to move upward until it hits the underside of the deflector 66 (see Fig. 1), Das Paper then moves under the diverter to rollers 39 and 40, but the paper lies against the underside the deflector 36, not against the surface of the knife 38. The deflector 66 thus serves as a "loop former", so that some slack is formed in the copy paper between rollers 35 »36 and 39» 40. If the Rollers 35 »36 stop, rolls 39t 40» take them keep rotating, this slack up. The knife finishes its cut before most of the slack has been used.

When the relay K1 drops out and when it opens normally When contacts K1-B are open, the timing clutch K-11 is also activated switched off. The cam 96 is brought to the stop 99 by a spring 100. A pin 101 is on the bottom of the cam provided. As soon as the clutch is switched off, the spring causes the cam 96 to return clockwise to its starting position, the cam stopping when the pin 101 touches the stop 99. The switch SW-H closes again when the cam 96 returns to its initial position. If at this time the relay K6 has not yet dropped out (as a result of the opening of the switch SW-X by the knife)

wire

and if the diode 0R12 is replaced by a simple! would, current through the contacts K6-A, the diode GR16 and the switch SW-H would pull the relay K1 again bring. This is prevented by the 0R12 diode. she is so polarized that prevents current through the contacts K6-A

10984B / 1336

flows to the winding of the relay K1 while it is permitted, that current through the contacts E1-D (if the relay K1 first picks up) via the switch SW-X and the relay of the relay K6. As for the 0R16 diode, this is provided to allow a current to flow through the switch SW1 to prevent the winding of the heater E6 at the same time as it flows through the winding of the relay K1. The transistor Q1 (in the switch SWi) cannot get enough current delivering / actuate both relays. Instead, guaranteed the diode 0R16 that the closing »of the switch SW1 directly the Controls excitation from only one relay K1. The subsequent closing of the contacts K1-D results in an energy supply of relay K6 (current flows through diode CR12).

The puncture of the GR11 diode is to divert the current into the Short-circuit winding of relay K1 when the relay drops out. This prevents excessive switching surges on the transistor Damage QI (part of switch SW1, see Pig. 3). One a similar diode is provided for each of the relays K2 and K3.

When the original continues towards the scanning window is transported, the leading edge operates the switch SW2 (actually this happens before the leading edge the Switch SW1 happens and the knife works). Closing the switch energizes relay K2. The Eontakte K2-B close to an alternate route for & s corona charging system through these contacts and the normally closed contacts K4-D su. Originally the corona charging current flowed through contacts K1-0. The corona charging circuit remains energized as long as relay E2 is actuated, even after relay K1 has fallen off. This is necessary because when the corona charging system is de-energized with the release of the relay K1 the trailing edge area of the cut copy sheet would not be loaded.

109845/1336

Although the normally closed contacts K2-A open when the relay K2 is energized, this has none Effect on the running of the time motor Ü2M1. The engine will kept in operation by the current flowing through the normally closed switch SW-B and the now closed switch SW-A as well as via the contacts K1-A flows in parallel.

When the original is moved past the scanning window, the copy paper is exposed. While the original continues to be scanned the leading edge operates switch SW3. Although relay K3 is operated, this has been done in single copy mode no impact. Similarly, its fall off at the end of the cycle has no effect whatsoever.

Eventually, if the cam 95 continues to rotate, one of the projections of the cam will open the switch SW-B. (According to 4, the projection 95b opens the switch SW-B, although it has already become clear that a different tab executes this operation during each cycle since the cam only performs one during each copy operation Third of a full turn.) When the switch SW-B is opened, the time motor TM1 stops. The cam 95 stops, with switches SW-E and SW-IP still closed so that the two exposure lamps remain on.

When the trailing edge of the original passes the switch SW2, the relay K2 drops out. When contacts K2-B open, the corona charging circuit is switched off. (The contacts K1-G are open at this time, since the relay K1 drops out before the relay K2.) Since the trailing edge of the copy paper is now out of the corona unit, further charging is unnecessary. When the relay K2 drops out, contacts K2 ~ A close. Since the contacts K5-O are always

109845/1336

are closed and the normally closed contacts K1-C return to their closed position when the relay K1 drops out, the time motor ΪΜ1 resumes its operation, although the switch SW-B is still open «Thus the cam begins to rotate counterclockwise. The switches SW-E and SW-I ¹ are still closed because of it. It is necessary to keep the exposure lamps energized until the exposure process is complete.

As soon as the cam 95 rotates a little further counterclockwise, the switch SW-B closes again in order to form a wec ^ Fs ^ ist &? Omkreis for the ^ eitmotor SM1. After the cam 95 has completed a third of a turn, the projections moving into the positions in the jig. 4 are in the positions shown (although each has moved 120 °) the switch SW-A opens. At this point the time motor switches off because contacts K1-A are open. Although the cam 95 begins rotating from its park position when the trailing edge of the original passes switch SW2 at the front of the scanning window, the original is by the time the cam 95 has rotated up to a third of a turn from its park position , has been fed completely past the scanning window, and the copy sheet has been completely fed past its exposure window. When the cam 95 is in its home position (although rotated 120 °), the switches SW-E and SW-I ¹ open and the two exposure lamps turn off.

The original and copy are placed on their respective receiving tables as they pass through the machine. At the end of this process, all switches and relays are in the positions shown in FIGS. 4 and 14, with the exception of the cam 95 'which has rotated through 120 °. However, since the cam has three symmetrically arranged projections, the cam ₉ is also in its initial position as far as the operation of the machine is concerned.

109845/1336

It is now assumed that the time motor has already stopped in its parking position when the trailing edge of the first Originals passes switch SW-2 and contacts K2-A close. When the leading edge of the second original meets the Has not yet reached switch SW1, contacts K1-0 also closed. (This will usually not be the pail when the second original is introduced into the machine after a long break in operation because the time motor 0S11 cannot reach its park position before a normal length original has passed switch SW2. It can (but occur somewhere in the process when several originals are fed into the machine one after the other.) In one In such cases, the time motor starts when the relay drops out K2 (when the trailing edge of the first original passes switch SW2) to start from its park position. It would Occasionally the timing motor would complete its cycle and turn off the exposure lamps while the second original still moved through the machine. However, this does not happen. The time motor completes its cycle of operation when the protrusion 95b opens the switch SW-A. However, when a second original is inserted into the machine was before the time motor has completed its cycle, contacts K1-A are closed to provide an alternative route for the motor current to be provided around the switch SW-A for the time at which this switch opens. The time motor then simply continues to run and enters a new cycle. If, of course, the time motor is its first When the cycle is complete, switches SW-E and SW-I open and the two exposure lamps turn off. If the original document would be within the sampling window at that time, part of it would not be completely au $ & em I copy sheet shown, whichever corresponds to the short interval, by which the two exposure lamps turn off, while crouching 95 makes a first turn by a third of the

109845/1336

Scope covered and another begins. However that is Time required for one of the projections on the crouch 95 to move from the position in which the switch SW-B is opened, moved to the position in which the switch SW-J. is opened, less than the time it takes an original document is required to get from switch SW1 to the scanning window which the time motor has passed its parking position when a new original is introduced into the machine (with the timing motor completing the cycle in progress and entering a new cycle) the exposure lamps momentarily flicker before the original document reaches the Sampling window reached - an interruption in sampling of the original does not occur.

It should be noted that in single cycle operation the switch SW-D is open. The relays K4- and & 5 are not energized. Similarly, switch SW-G is open, and since contacts K4-D also remain open, the timing motor runs QM2 does not. The Eelais E4 and K ^ as well as the time motor TM2 work only! driving the multiple copy operation.

In the case of multiple copy operation, the i \ inction process is the same as in the single copy operation, except that when the leading edge of the original presses switch SW3 during the first Scan cycle actuated, a series of control circuits to be activated. These control circuits reverse the normal running of the original transport system when the trailing edge of the original releases switch SW3. The ° riginal runs back at high speed. The control circuits also prevent the machine from making a copy while the original is being moved back.

109345/1336

When the leading edge of the original releases the switch SV2 during Bücklaufs at high speed, the transport system is normal, so that the original _S is conveyed again in the forward direction to be scanned at once. This process is repeated until the multiple copy selector is reset to the "1" position, at which point the last scan begins, during which the machine operates in single copy mode. The multiple copy selector switch has two cam surfaces 102 and 103. The cam surface 102 has 16 locking positions which are distributed equidistantly on the circumference of the cam. The actuating arm for the switch SW-O slides on the cam surface. When the actuator arm is on a high portion of the cam surface (between locked positions), switch SW-C is closed. Each time the cam surface 102 is rotated, the actuator arm falls into a lock and the switch SW-O opens. When the timing motor TM2 is first energized, the cam surface 102 begins to rotate counterclockwise. The actuator arm of switch SW-O moves to a high point on cam surface 102 to close the switch. The control circuit, which initially triggers the rotation of the time motor, is switched off soon after the start of the time motor, but if it remains switched on long enough, the "locking circuit", which is established by closing the switch SW-O, ensures that the time motor is continuous continues to operate until the actuator arm falls into the next lock on the cam surface 102. At this point the time motor IM2 stops.

The cam surface 10J has only one lock. The barrier is mounted in such a position that it enables the actuation of the switch arm SW-D, which on

109845/1336

the Uockenflache grinds, so that this is only in the Lock is in when the multicopy selector is up is in the "single copy mode" position. When the actuating arm is in the lock, the switch is open. The switch SW-D controls the sequence circuits for multiple copy operation. When the selector switch is from. Hand is turned to a position that represents the number of copies desired, both the surfaces of the cam 102 and the cam 103 are set in rotation. When the switch SW-D is closed, the multi-copy mode is active guaranteed * If, however, the dial is turned further, the switch SW-D opens when the number "1" appears on the dial in the "12 o'clock" position.

After the original has been returned for the last time, the last of the required number of copies will be in made in the same way that a single copy is made.

Up to the point where the switch SW3 first appeared is operated by the leading edge of the original, the operation in the multiple copy mode is the same as that in the Single copy mode. When the switch SWJ and When relay KJ is operating, contacts K3-B are closed, u .. to energize the relay K ^. Now electricity overflows the contacts K3-B, the relay coil and the switch SW-D, the switch SW-D being closed by the cam surface 103 if more than one copy is made.

When contacts K5-D close, current flows through the field winding the multiple copy clutch K-8. The operation this coupling couples the cam 104- (see I "ig.6) with the Drive chain 75 (see Fig. 2). The cam 104 thus rotates

109345/1336

in the forward direction (counterclockwise) as shown in FIG. (It is an unrepresented one Gears are provided to reduce the speed of the cam 104 with respect to the drive chain. The cam 104 makes less than one turn, even with a long original.) The switch SW-Q is normally closed. As the cam 104 continues to rotate forward, the switch SW-Q in the exciter circuit opens for the relay KI. However, relay K1 remains energized. AuGh after 20 cm (8 inches) of copy paper is inserted into the machine were, the switch SW-H is opened by the cam 96, the relay K1 remains through the normally closed contacts K4-B and the switch SW1 energized flowing current until the trailing edge of the original enables this switch.

When the relay KJ? is energized first, the contacts open K5-0. It should be remembered that in single copy mode the time motor TIiI does not operate until relay K1 is energized and contacts K1-A close. The time motor continues to operate until switch SW-B opens, at which point Time the time motor is parked. If the relay K2 drops out and the contacts K2-A close (whereby the contacts K1-C closed earlier), the time motor continues to operate until the cam 95 has completed a third of a turn Has. However, when the relay K ^ is energized and the contacts K5-0 are open in multicopy mode, the The time motor does not resume its operation if the relay K2 drops out and the contacts K2-A close. Consequently the time motor remains parked via multicopy mode. The switches SW-E. And SW-F remain closed and the exposure lamps remain in operation, namely during of the entire multicopy cycle. Only if the the last copy was made and the relay K5 has dropped out because the switch SW-D has opened, this enables

109845/1336

that the last drop of relay K2 allows the timing motor to resume operation. Thus rotates Even in the multiple copy mode, the cam 95 changes by only 120 °.

When the leading edge of the original has arrived at switch SWJ the relays KT, K2, KJ and K5 are energized, the corona circuit is still excited by the contacts K1-Ö and via the alternative circuit, which the contacts Includes K2-B and K4-D, and the copy paper roll clutch K-12 is still energized via the normally open (now closed) contacts K1-B. The exposure lamp second engine TM1 is parked as soon as the cam 95 has rotated a sufficient amount of rotation around the switch SW-B su open. The timing clutch K-11 is still energized, since the normally open contacts K1-B are closed. Assuming that the length of the original is greater is than 20 cm (8 inches), switch SW-H is open. The crouch 104- continues its rotation in the forward direction away.

The scanning and exposure process continues until the trailing edge of the original releases the switch SW1 and the relay K1 drops out. When the normally open contacts K1-B open, the paper roller clutch K-12 is de-energized to stop the copy paper feed. At the same time, the knife solenoid K-IO ₉ works to cut the copy paper to the length of the original. Since the normally open contacts K1-B ^ are open ow, the time coupling K-11 is de-energized and the _$! Spring 100 brings the squatting 96 back to the starting position. The relay K6 falls upon opening of the switch SW-S from _s and this in turn causes the knife returns to its starting position.

109845/1336

• The trailing edge of the original then gives the scanning window free. The scanning and exposure process is now complete and the copy sheet is being developed. The copy will then placed in the copy receiving tray. When the trailing edge of the original releases the SWJ switch, the Relay KJ de-energized. While relay KJ was energized, normally closed switches Kj-A were open and the normally open contacts KJ-A were closed. Since the contacts K4-0 were open, the Heiais K4 doesn't work. However, when the normally closed contacts KJ-A close, the relay K4 picks up, since it closes this time the contacts KJ? -B are closed. When falling A number of operations take place on relay K4.

Originally the contacts K4-D and Kj-D and the switch SW-O were open so that the time motor ΉΪ2 could not work. As soon as the rear edge of the original passes the switch SWJ, the relay KJ drops out and the contacts KJ-D close. Since relay K4 picks up and contacts K4-D close at the same time, current flows through these contacts and contacts KJ-D to time motor ΪΗ2. The timing motor will begin to turn the multicopy selector counterclockwise. However, the O _r igi _na i immediately begins its backward movement through the machine, the Heiais KJ immediately drops out, and the contacts KJ-D open. At this time, the cam 107 has not yet made sufficient rotation so that the operating arm of the switch SW-C is at a high portion of the cam surface 102. The locks on the cam 102 are sufficiently wide to prevent the switch SW-O from closing during the brief interval during which the relay KJ has dropped out. While the switch SV-O is still open, if the relay Kj drops out, the time motor ΪΜ2 stops its operation. The selector switch is not moved any further at this time.

109845/1336

The switch to be operated first during reverse travel is the switch SWj, and thus the relay KJ picks up. The relay K4 is only actuated when the relay KJ has dropped out and the normally closed contacts K3-A are closed. Although these contacts are now open, the relay remains K4 is excited by the current flowing through the normally open contacts KJ-A (now closed) and the contacts K4-C flows. So that the contacts K4-G during the switching of the contacts KJ-A do not open, the relay K4 is prevented from dropping out, through the current which flows through the capacitor 04, this current continuing to flow until the normally open contacts KJ-A conclude. The relay KJ was originally used when energizing of the relay KJ and when the contacts KJ-B close. As a result, the relay was when the relay K2 and alternately excited when the contacts K2-D are closed. At the end of the forward movement, the contacts KJ-B opened at Relay KJ dropped out, but the alternate excitation path kept relay KJ energized. When the contacts KJ-B at the start of the backward movement, the relay KJ is through the The current flowing through both paths is kept attracted.

The original continues moving in the reverse direction. When relay K1 has dropped out and in the open state the normally open contacts K1-B, the clutch K-12 is not operated, so that no copy paper feed occurs, and the clutch K-11 is also not operated, so that the cam 96 does not rotate. The relay K5 is still energized and contacts K5-D are still closed, the multiple copy clutch K-8 is still activated, and the cam 104 is still coupled to the drive chain 75. However, since the drive chain is now backwards moves, cam 104 also moves in the reverse direction (clockwise). The cam, which on

109845/1336

2119637

^ ui ^ the turntable movement is in such a position, as indicated in FIG. 6 by the reference number 106 is (the exact position depends on the length of the original ab) begins »in its starting position in the area dee Stop 105 to move.

The original continues to reverse and the cam 104 continues to its home position. The trailing edge of the original actuates the switch SW2, which causes the relay K2 to drop out. Although the contacts K2-D are open are, the relay K5 is through the contacts K3-B kept dressed. The relay K4 is now over his own contacts K4-C held, via both contacts KJ-A and K2-0. The trailing edge of the original is operated then switch SW1. This has no effect on that Relay K1, however, since switch SW-Q is open and since relay K4 is energized, the normally closed Switch K4-B also open. (It should be noted that the switch SW1 is activated by the normally open contacts K4-B (now closed) in the lifting circuit similarly, this condition cannot control the energization of relay K1.) Finally, the Cam 104 back enough to close switch SW-Q. Current flows through the normally open Contacts K4-B (now closed) and in parallel via the switch SW ^ uIsIr the switch SW-Q and the relay coil. at a short original, the trailing edge may not control the closing of the switch SWi at the time at which the Switch SW-Q closes. For this purpose are usually open parallel contacts K4-B are provided, then the Relay K1 energized when switch SW-Q closes even if switch SW1 is not yet closed. This is required as the relay KI has to work to keep the forward

109845/1336

start feeding. when, the switch SW-Q closes, so that a proper registration takes place when the next forward movement starts.

The actual time at which the relay £ 1 picks up, as a result of the closing of the switch SW-Q, is variable and depends on the length of the original. As described above, the multiple copy clutch K-8 is operated when the contacts K5-D are closed. These contacts close only _s when the Eelais K5 attracts as a result of the closing of the contacts KJ-B, which are closed when the excitation of the Eelais KJ, "when the leading edge of the original operates the switch SW3 'rotates At this time, in the forward movement If the trailing edge of the original releases switch SWj, the rollers in the original drive device are reversed. The multiple copy clutch K-8 is still protruding and 'consequently the cam 104 is driven in the rearward direction.

The cam surface of the cam 104 is shaped as shown in FIG. The section 104a of the cam surface operates the switch SW-Q during the backward movement of the cam 104, namely before the cam is completely returned to its original position. consequently, relay K1 is energized and copy feeding begins before the leading edge of the original has reached switch SWJ. The forward movement speed, bsw. the forward moving rate of the copy paper and the Hückwärtsbewegungsrate of OriginsJLs, like the IORM of the cam 104 designed so * that the front edge of the ^U riginals the SK2 switch reaches zur.selben time, at which the copying paper introduced so far into the machine such that the leading edge of which has reached the copy exposure window.

109845/1336

When the switch SW-Q is closed and the relay K1 is energized, the corona circuit is activated again via the contacts K1-G actuated. The copy paper roller clutch K-12 is also excited via the normally open contacts K1-B. Similarly, the timing clutch K-11 energized when closing normally open contacts E1-B. It can thus be seen that when closing the Switch SW-Q starts the copy feed cycle · While in single copy mode, copy feed starts when the leading edge of the original operates switch SW1, this is not the pail in the multiple copy mode. In multi-copy mode copy feeding starts when the auxiliary feed switch SW-Q closes.

Finally, the trailing edge of the original flips the switch SW1, which provides an alternative current path around normally open contacts K4-B (now closed). 5OIgIich the relay K1 remains picked up even then, after the relay K4 has dropped out.

When the leading edge of the original releases the switch SW3, the relay KJ drops out. This in turn opens the contacts K5-D to switch off the multi-copy clutch K-8. At this time, the cam 104 is in its initial position, because the leading edge of the original is next to switch SW3. To ensure that the cam 104 always starts from the same starting position, i.e. to prevent cumulative registration errors from occurring, the cam 104 is equipped with a spring (not shown) to return it to its starting position, when the clutch K-8 disconnects. Although the normally open contacts KJ-A open when the relay KJ drops out, the relay K2 is still energized, so that the relay K4 is energized by the current flowing through the contacts K2-0 and K4-0 remain.

10S84S / t336

If the relay KJ has dropped out and if the relay K4 is picked up, the time motor ΊΜ2 starts its operation again. This time, however, relay KJ is not immediately re-energized and cam 102 moves enough to close switch SW-O. The switch SW-C is closed before the relay K2 drops out when the leading edge of the original releases the switch SW2. The closed switch keeps the timing motor 3M2 energized until the dial is one position back and the switch opens. The time it takes for the time motor W.2 to reset the dial is no longer than the time it takes for the leading edge of the original to move from switch SWJ to switch SW2 (at the end of which relay K4 drops out). Thus, by the time the dial is reset and switch SW-G is open, contacts K4-D have opened. This prevents the timing motor TM2 from starting a second cycle of operation.

Original continues to move in the reverse direction until the leading edge releases switch SW2. That Relay K2 drops out, and when contacts K2-C open, relay K4 drops out. When the contacts K4-A are in their starting position return, the reverse clutch K-7 is turned off and the forward clutch K-9 is turned on. Thus begins the leading edge of the original, which is the original scanning window and the switch adjacent to it SW2 has just released its movement in the forward direction.

At this point the relays K1 and K2 are energized during operation, and relays K3, K4 and & 5 drop out. As soon as that Relay K1 drops out when the trailing edge of the original is on

109845/1336

Switch SW1 passes, the copy paper roll feeder stops on and the knife solenoid K-10 is operated. The rest of the cycle is the same as the first cycle. In similarly, subsequent cycles are identical to the second cycle. The multiple copy selector is turned to reset every copy cycle. Finally, the multicopy selector is returned to the single copy position. Since the switch SW-D is then open (the completion of the penultimate copy cycle) and the relays K4- and K5 cannot work, is the last copy cycle same as the one in single copy mode, except that the paper feed has already started, the last one Initiate backward movement of the original.

It will be recalled that the cam 95 was left in its park position when one of its protrusions the switch SW-B has opened, since when the relay KJ? is operated during the first forward movement of the original (the relay operates before switch SW-B opens), contacts K ^ -C opened. Although these contacts close, when the relay K ^ drops out (when the leading edge is the original releases switch SW3), has the trailing edge at this time of the original caused the relay K2 to pull in, so that thereby the contacts K2-A open. And the time at which the relay K2 drops out, the relay K5 has picked up again. Thus, at all times during the oscillation of the original there is one of the contacts K2-A or K5-C open, cam 95 remains parked, and the two exposure lamps remain on. Only during the last forward movement of the original when the relay K2 drops ", the relay K5 remains unactuated. At this time both contact K5-C and contact K2-A are closed, and the cam 95 completes its 120 ° rotation, where one of the protrusions goes from switch SW-B to switch SW-A.

109845/1336

The arrangement of the switch SW1, the switch SWQ and the normally open and normally closed Eontakte K4-B should be noted. The two pairs of contacts allow the two switches to control energization of relay K1 during different parts of the cycle. During the first forward movement of the original, when relay K4 is de-energized, switch SW1 controls energization of the relay K1 and the start of the copier feed, in the same way as in the single copy mode. Since the relay K4 is energized during each backward movement of the original, the switch SWQ then controls the Start of copy paper feeding. The "early" start of the copy paper feed is only necessary during the cycles that follow the first.

During the scanning process (the process by which a latent image is formed on the copy sheet) must any point on the copy paper will remain "locked" to a specific point on the original. Otherwise, each point on the copy sheet will be illuminated by light coming from more than one corresponding one Point of the original is reflected. The corresponding point of the image for each object point is through the intersection the image focal plane with an idnie determines which of the object point is related by the nodal points of the lens. (The nodal points of the lens are such points on the. Lens axis, that one incident at a certain angle to the lens axis through the first node Ray leaves the second node at the same angle to the axis.)

109845/1336

It follows that the leading edge of the copy sheet and the leading edge of the original are marked by a straight line through the Lens nodes at all times during the scan need to be cut. This in turn requires that the distance between the leading edge of the copy sheet and the optical axis in the image plane (the intersection of the optical axis of the copier with the exposure window) equal to the distance of the leading edge of the original from the optical axis in the object plane (the intersection of the optical Axis of the machine with the scanning window) at all times must be during the scanning process. This "optical synchronization" must have already been achieved by the time the scanning process begins. Once this is achieved in this way, it is maintained as the original and the copy sheet move past their respective pensters at the same speed.

The optical synchronization described above must be distinguished from the lens angle over which the scan actually takes place. As long as the optical synchronization is present, light can be reflected from the original and onto the Copy plate are directed. Corresponding points on the original and on the copy sheet move towards each other synchronous. However, it is not necessary that an exposure take place at all times when the optical synchronization given is. In fact, some means are generally provided to adjust the time during which each point on the copy sheet is exposed so that the contrast of the finished copy can be changed.

The front edge of the copy sheet is first a few steps in front of the optical axis within the exposure window illuminated. This distance is in the machine's

109845 / 133B

Fig. 1 set because the shutter only the rear edge of the Window ". In such machines, which are equipped with closure plates on both sides of the window, the leading edge of the copy sheet is first illuminated at a point in front of the optical axis, which is through the exposure setting is fixed. As practical Measure, the length of the scanning window is kept short enough so that the optical system is able to all points on the copy sheet corresponding to all points within the physical limits of the scan window above to expose on the machine (provided that the physical dimensions of the exposure window are such allow extensive exposure). This means that in all cases only required for optical synchronization is that if the original just passed the scanning window reached (the exposure cannot take place at all before this point in time) and by a certain distance from that The intersection of the optical axis with the scanning window is removed, the leading edge of the copy sheet around the same Distance from the intersection of the optical axis with the exposure window must be removed.

Fig. I5 shows the book copier addendum, as it is on top of the Copy machine (see Fig. 8) is attached., The book copier attachment comprises a pair of rails 151 and 152. As shown in Fig. 16, the rail 15I includes a bracket 186, from which a pin 185 protrudes. The bracket 187 of the rail 152 includes a pin 185 which on the another of the brackets 1 $ 8 is arranged in front of the machine. Each pin is in the groove of one of the brackets I38 on the Located at the front of the machine, and the back of each rail is then turned down to the point where there is an extension of one of the rails 156 and 135

109845/1336

forms. As shown in FIG. 16, the rail 151 is locked in place, but the rail I52 is in the position it is currently in before it is pressed down. Each of the rails includes one Bolt 148 together with a button 149 which protrudes from a slot 161 in the rail. When the bolt 148 is moved in rail 152 in the direction of arrow 189 in FIG. 16, it will be apparent that the rail can be rotated in the direction of arrow 190 to the point where it meets the front of rail 135 flees. The rail 135 includes a bore into which the bolt 148 can be extended. Similar hole is provided in the rail 156 for the bolt 148 in the rail 151. In this way, both rails can be rigid be attached to the top of the copier 10.

As shown in Fig. 16, a connecting pin extends 188 down from the rail 152. When the rail 152 is in place, the connecting pin 188 with the connecting pin 132 is at the top of the Copy machine in action. This is best seen in FIG.

15 shows the two rails in their position, and although together with the plates, the plates are drawn in partially broken away representation. The plate is made from a metal frame 143 which surrounds a glass plate 144.

At the beginning of the copying sequence, the leading edge of the object to be copied is just in front of the leading edge of the scanning window 137. During the copy cycle, the platen moves to the right. After that, it will turn into the opposite Reversed direction, so that it turns into the position shown in

109845/1336

placed location is brought. A heavy blanket 145 is attached to the rear of the frame 143 by a bracket 146 attached, the rubber blanket serving to press the book firmly down on the plate.

In the upper left corner of Figure 15 is a guide which extends from the plate 145 from and which is contained in a groove 156a of the rail 156 (see Fig. 20). A similar guide 143d is provided on the other side of the plate to engage in groove 155a of the Rail 135 to run (see Fig. 20). To put the plate in the Insert rails, the spring 133 is raised slightly, so that it releases the pin 142 and is then rotated clockwise (see Fig. 15) "in the phantom-like position shown, this allows the plate to be inserted into the two guide rails 135 and 156 and attached to the can be slid along the entire front of the machine. After the plate is fully inserted the spring Ί33 in the position shown in FIG moved back, whereby the backward movement of the plate is limited when the rear of the guide 143c against the Spring 133 is applied. Each of the rails I51 and 152 includes one Groove which is a continuation of the corresponding groove in the corresponding one of the rails 156 and 135 around the To allow plate to be moved in the forward direction.

The HetalIplatte 143 has a cross section as shown in Fig. 20. In addition to the guides 143c and 14pd for guiding the plate along the rails within the Killen are on the side of the plate that is below the four switches on top of the copier two vertical guides 143a and 143b

109845/13

see. A movable cam 15t- is inserted between the two guides. A lever 153 connected to the movable cam 154- serves to adjust the cycle of the machine in accordance with the length of the original to be copied. In Fig. 15, the lever 153 sn of the back of the book 14-7 is shown, both sides of the book, which point downward against the plate, are copied. If the lever were moved to the right in the center of the book, only the right side of the book would be copied.

Guide 14-3b not only serves as one of the two barriers to accommodate cam 154-, it also acts as a cam to operate the four switches on top of the machine. The fingers of all four switches slide on the cam 143b. At the beginning of the copy cycle, the leading edge of the cam, indicated by reference numeral 14-Jb ¹ in Figure 18, is turned toward the back of the finger of switch S2A. Switches S2A and S3A are open, while switches SQ1 and S1B, whose fingers are initially on cam 14-3b, are closed. When the copying sequence begins, the platen moves to the left in Figure 18 and the leading edge of cam 143b closes switch S2A and then switch Sj3A. The trailing edge of the cam, identified by the reference numeral 14-3b ", finally releases the switch SiB at a time the switch opens (currently the cam 154- is neglected). The trailing edge of the cam is there then switch SQ1 free at a time at which this switch also opens .. In a similar manner, switches S2A and follow in the sequence

109845/1336

_ 54 -

The function of the cam lobe 154 is to effectively increase the length of the cam which operates the various switches. As shown in FIG. 18, when the lever 153 is in the position shown, the end of the cam 154 extends well beyond the rearward end 143b "of the cam 143b. In such a case, a more pronounced forward movement is required before the open different switches. There is no need to increase the effective length of the cam, many operate the switches in the forward direction. At the beginning of any copy cycle, the leading edge of the combined crouch should be in the position shown in Figure 18, ie, just in front of the finger of switch S2A. When lever 153 is moved completely to the left in Figure 18, it can be seen that the lever is at a corresponding point in front of switch SQ1 -b 'and provided with a protruding pin 154a. When the cam is moved to the left in Fig. 18, the front of the cam is above one Groove 143a ^{1 arranged} in the guide 143a. Usually the pin 154a rests on a guide 143a, as shown in S ¹ Ig. 18 and 20 is shown. However, when the cam is moved all the way to the left, its front side drops down when crouching due to the recess 154-b, which serves as a so-called "weak point". The pin 154a hits a corner of the hat 143a'i, as shown in FIG. 19, in order to avoid further movement to the left of the cam. In such a position it can be seen that the front side 143b ^{1 of} the attached cam 143 still represents the effective front side of the cam combination. As far as the rear of the cam combination is concerned, the back of the cam 154 is located slightly to the left of the end 143b "of the iiuekeru;? 4> b, and thus the cam 143b only controls the operation of the four switches. The stop 157 is provided around the To limit the backward movement of the cam> 54, so that a maximum of copy sheet length is achieved.

109845/1336

As will be described in more detail below, the pingers S2A, S3A and S1B walk on both squats. The movable cam extension 154- serves to extend the opening of these three switches when the plate is in the I ¹ Xg. 18 is moved to the left. This can be seen most clearly from FIG. Although this figure does not show the panel on the machine, it can be clearly seen that the finger of switch SQ1 does not extend as far from the rail 135 out of the panel as the fingers of the other three switches. When the plate is placed on the main machine, the finger of the switch SQ1 does not rest on the attached cam 143b. This is also shown in FIG.

The rail 135 includes a hollow passage 135b through which conductors (not shown) with the four switches connected, and the start button S1A can be connected to the control circuit inside the machine

In the case of the letter copier, the face of the person to be copied becomes Document guided along the scanning window 137. The optical system of the machine is designed in such a way that the Eujnme the distances between the top of the scanning window and the mirror (shown by arrow 178 in Figure 17) and between the point of reflection on the mirror and the exposure window (shown in FIG. 17 by arrow 177) delivers perfect focusing in the exposure window. However, when the glass plate is in its position is brought, becomes the total distance of the optical path The stiffness of the plate is enlarged and it becomes that anyway voxiiandenen path is added between the scanning window and the plate. The magnified distance is in the £ .17 by the Arrow 179 indicated, and when the increase in the optical path Failure to compensate could result in poor focus at the B (; light window open tx-eten, if shown: oyster in BuchlcoL'J ornoduo operated vri.i'd.

109845/1336

For this. G-round becomes when the book copier suffix is on the Haschine is put on, the mirror 176 in the year. 17th moved to the right, i.e., towards the exposure window. While the optical path from the mirror to the too If the copying document is enlarged due to the thickness of the plate, the optical path from the mirror to the exposure window becomes decreased due to the movement of the mirror.

On the side of the copying machine on which the rail 151 is arranged, a lever 162 is provided which has two recesses 162a and 162b. Through each of these Recesses runs a pin 163 and 164, which movement of the lever 162 in the direction shown by arrow 191 is limited. A spring 165 is on hers attached to the lever at its lower end, as shown at 167, and to a pin 166 at its upper end attached to the machine. The spring 165 has a tendency to bias the lever 162 upwards and the * Lever is normally in the phantom position shown in FIG. However, when the rail 151 is on the Haschine is put on, its rear end pushes against the lever 163 and moves the lever down into the in the Position shown in the drawing.

On the side of the lever there is provided a rack 167 which meshes with a pinion 169. When the lever is moved downward, the pinion 169 rotates counterclockwise as shown by arrow I70. the mirror -176 is attached to a socket 175, which is mounted on a platform 173. The platform has two recesses 173a through which two pins 174- protrude. The pins are / a stationary platform 172 attached. It is obvious that this is a movement the platform 173 to the left and right in FIG. 17

109845/1336

to and from the exposure window viog. The shaft 181 attached to the pinion 169 carries a liizenternocken 182 as shown in FIG. When the tickle 169 rotates counterclockwise, with the rail 151 attached to the machine, the JSccentric cam 182 (see arrow 183) is rotated into the position shown in FIG. 17 in which the clamp 180 (and thus the platform 173 > the connector 175 and the mirror 176) is moved to the right.

21 shows the plug connections within the connector 188 on the rail 152. When the rail is on the Machine is arranged, the control circuit of Fig.J. modified by connections 132 and 188. The resulting Control circuit is shown in FIG. 22, in which the oteckers themselves are not identified and the circuit elements not in function are omitted. All switches are shown in their starting position (Switch S2A and switch S3A are open while switches SQI and S1B are closed).

After the book page to be copied is placed on the glass plate and the cam extension 154- is moved so that it is with corresponds to the length of the original page to be copied (the length of the desired copy page), the switch SIA is up manually operated on the rail 135. Current then flows through switch S1A, through the normally closed contacts K4-B and through the winding of the relay Ki (see Fig.22). The relay M picks up, the contacts K1-D close, and current flows through the contacts, the diode CKi6 and the switch S1B (on the rail) to the Eelais Ki also then energized

109845/1336

to be held when the operator lets go of the SiA container. Current also flows through the contacts Ki-B, the diode üEi2, the switch SW-X and the winding of the IUi relay K6. The heater K6 operates and contacts K6-A close to keep the heater energized. The -arrc ^ ung of the Heiais K6 prepares the Hessersolenoid circuit, the contacts K6-B are now closed and the normally closed contacts K1-B are open, so that when the relay Ki drops out, the Hessersolenoid K-IO can work.

As in the letter copy ermo dus, the excitement of Helais Κί leads to that the normally open contacts Ki-B are closed and to excite the timing clutch K-Ii and the paper clutch K-12.

Although cam 96 is used in the letter copy mode to open switch SW-H after about 20 cm (6 inches) of copy paper has been fed from the pile, switch SW-H is not included in the book copy circuit. Instead, switch S1B on rail 135 is used to control the length of the cut copy sheet to match the length set by the operator, with a minimum length of 8 inches. In the book copy mode, the cam 96 is used to control the closing of the switch SW-O. (The switch SW-O is ^{not shown in Ji 1} Xg.14 because the plug J in the letter copy ermo dus (see JTig.j), with which the switch SW-O ν is blind, is left floating (see J? ig.13) ·)

The initial operation of the Heiais Ki also leads to the excitation of the dual motor ΤΙΊ1 (via the contacts K1-A and the switch or 3W-B), as in the case of the letter copier module.

lais Ki drops (until the squat finally the switch SV / -E opens). When the crouch begins to rotate, close it the switches SW-E and SW-F to supply the two exposure flaps with energy. Closing the normally open Contacts K1-0 also lead to the excitation of the corona energy "j (J9 as in letter copieriiiodus.

Buchplattc is comparatively long, uri are also long originals to support. When the book plate begins its movement from a division in which the leading edge is forward of roller Ί6 (see Fig. i), the plate extends far beyond the! underside of the machine. To limit the hatred around which the plate extends beyond the rear of the machine, the plate is initially positioned so that that its leading edge is in the area of the roller 17 on the upper side ebr Haschine.

Referring to Fig. 13, it should be recalled that in the letter copy mode, the forward clutch IC-9 is normally engaged so that an original document inserted into the nip of the feed rollers is promptly transported through the machine. In the book copy mode, however, as can be seen from Fig. <Lci , the winding of the forward clutch K-9 is in addition to being in series with the contacts K4-A, also in series with the parallel paths which the switch SW -O and contacts K ^ -D include. Both the contacts and the switch are normally open and the forward clutch K-9 is not actuated.

Only when the squat 96 has rotated through an angle which is indicated in FIG. 7 by the arrow d2. shown i.vfc, the switch SW-O closes. The angle d ^ _ corresponds to the distance that the copy sheet must cover before it does

109845/1336

Exposure window reached. Since the cam 96 its movement starts at the same time as the copy sheet (since both the timing clutch E-11 and the paper clutch E-12 are initially are excited by closing contacts K1-B), is it obvious that there? Switch SW-O closes to the To energize forward clutch E-9 just when the copy sheet reached the exposure window. At this time the platen is moving forward as rollers 16, 17 and 18 in Rotate forward direction.

Initially, the front of the cam is in front of the finger of switch S2A on top of the machine. After this As the plate begins moving in the forward direction, the front of cam 143b closes switch S2A. As shown in FIG. 22, the relay K2 operates when the switch closes. Although initially located in front of the edge of the scanning window, das.Heiais K2 not operated until the copy sheet reaches the exposure window and the plate starts moving from the initial position.

When relay K2 is picked up, contacts E2-G close, to prepare a hold path for relay E4-, x ^ enn this will eventually attract. Contacts K2-B close to create a holding path for corona 89, and this even after relay K1 drops out and contacts K1-C open.

Finally, when the plate continues to move forward, the leading edge of the cam closes switch SJA (see Fig. 18). This switch corresponds to the switch SW;, - in the letter copying mode. When the switch closes, the relay k'y picks up , the contacts KJ-B close, and the relay K ^ picks up. Although the relays KA and K5 in

109845/1336

-Dl-

Letter copy mode won't work unless multiple copies are made are to be made, the two Heiais attract even if a single copy is made in book copy mode will. This is because if a single copy is made, the disk will be after the copy cycle must be transported in the opposite direction in order to maintain the system for another cycle of operation prepare.

When relay K3 is operated, only relay K5 picks up. Although contacts Ii ^ -B close, normally closed contacts KJ-A open first (relay KJ picks up before relay K5) so that no current flows through the winding of relay K4. Otherwise it would happen that a current could flow through the contacts K ^ -B and the capacitor 04. However, the capacitor 04, which is initially discharged, is of considerable size and thus allows a large current to flow through it when the contacts K ^ -B close to the capacitor 04 via the contacts and winding of the relay K4 with the Connect rail 115. The strong current flowing through the capacitor «Discharges it quickly. A strong and very short current pulse occurs through the winding of relay K4-. The pulse does not have a sufficient duration to control the energization of relay K4. The capacitor 04 works in the book copy mode exactly as it works in the letter copy mode in order to keep the relay K4 energized after it is initially energized in the later sequence and the contacts K3-A transfer.

As the plate continues to move forward, the trailing edge of the cam 14Jb or cam extension goes 154 · pass »counter S1B. Let it be remembered that the trailing edge of the crouch extension is the length of the original document introduced by the operator

109845/1336

(if it is larger than 20 cm (8 inches)). When the trailing edge of the crouching extension passes switch S1B, this is equivalent to when the trailing edge of the original document passes switch SWi in letter copying mode. The heat Ki is kept bit excited via the contacts K1-D, the diode CK16 and the switch. When the switch is opened, the HeIals Ki falls off. It should be noted that the switch SiB only trips when the trailing edge of the cam extension; 154- cn passes him. If the crouch change does not extend beyond the rear edge of the fixed hook, switch S1B is opened by the rear edge of the fixed hook. By the time the trailing edge of the fixed cam passes the switch gate SiB, at least 20 cm (8 inches) of copy paper has been fed from the roll. For this reason, the switch SW-H is not required in the book copying mode, while the minimum length of the copy paper sheet is controlled by the trailing edge of the fixed cam 14Jb, while a longer length is controlled by the crouching extension '* j ^L V.

If the Heiais drops K1, open the normally c ~ ^e opened contacts Ki-B, and both the Jrapierkupplung KI '■. -. as well as the timing clutch K-11 are switched off. The paper roll feed stops and the sock 96 returns to its original position, under the control of the i'eder 100. In connection with this curling, it should be noted that when the corner has rotated an angle d2 and the Switch SW-ü closes, the forward clutch K-9 is energized in the manner described above. The forward clutch is only energized when the copy sheet has reached the 3rd light window. if

1098A5 / 1338

If K5 works, the current flows via the forward clutch IC-9, but also via the contacts K ^ -D. For this purpose there is no need for the ÖcMter SW-O to remain closed. The relay K ^ picks up when the helix iv-3 picks up, and the helix K5 picks up when the leading edge of the fixed cam 14Jb reaches the container SpA. Thus, the switch SW-O only has to remain closed until the! Cam 145b reaches the switch S5A. This corresponds to an original document movement in the letter copying mode from the switch Svfö sum switch SW $. This is a very short distance. The protrusion of cam 96 (represented by angle dl) corresponds to a much greater distance than that, dex ¹ large angles being required when the system is operating in the hi-profile mode, as will be described below. In any event, the protrusion on the crouch 96 holds the switch SW-O closed until the heater K5 pulls to keep the forward clutch K-9 energized. When the time clutch Iv-i'i is switched off, the NQcken 96 returns to its starting position, but the forward clutch K-9 remains via the contacts -D.

Although contacts K1-0 open, it should be remembered that contacts K2-3 are now closed so that the corona power supply 89 remains energized. The scanning and exposure sequence is continued in J ¹ all of the letter copying mode.

Eventually, the trailing edge of the cam 154 will bypass the switch SCA (or the trailing edge of the iTockens'^; 43b for a short original with no cam extension). The switch opens, and the fellais K2. falls off. The contacts K2-B open and the corona energy supply is switched off. The K5 fall is still over the closed contacts K5-3. The relay K5 is also excited via the closed contacts L ^ -k and the now closed contacts K.-.- D ei *.

109845/13 ^ 6

This alternative way keeps the relay K5 energized, namely also after the relay K3 drops out and the contacts K3-B open.

The plate continues its movement Ms to the position in which the original to be copied the scanning window completely releases. At this time enter the trailing edge of the cam extension 154 or the rear of the solid Cam 143b releases switch S3A if the original is shorter is than 20 cm (8 inches). The relay K3 drops out and the contacts K3-B open, but the relay K5 is activated accordingly of the above description kept energized via contacts K5-A and ΚΞ-D. At this time the relay K4 is overworking the contacts K5-B and the normally closed contacts K3-A, xvelche now close. As soon as the Eelais picks up, the contacts K4-G close, but there normally If contacts K3-A are open and contacts K2-0 are open, relay K4 is not activated via contacts K4-0 kept excited.

When the relay K4 is picked up, however, the normally closed contacts K4-A are opened and the forward clutch is opened K-9 is switched off. The normally open contacts K4-A close to energize the reverse clutch K-7. if the plate begins to move in the opposite direction with the rotation of rollers 16, 17 and 18 on top of the machine, the trailing edge of the extension cam 154 will close switch S3A. The Eelais K3 attracts again. At this time the normally open contacts K3-A close to create a holding path for the Eelais Form K4 via contacts K4-C. Although the normally closed contacts K3-A are initially the Heiais K4 keep excited and these contacts are now open the capacitor G4 energizes the E ^ lais K4 until the contacts K3-A transmit, in exactly the same way as in letter copy mode.

109845/13

When the contacts K3-B close, the relay KJ is over kept energized a path which includes these contacts, further via a path which includes contacts K5-A and K2-D. The new path, which includes the contacts KJ-B, is necessary because the reversal continues of the plate in the opposite direction the relay K2 is actuated, while at this time the contacts K2-D to open.

Eventually, as the plate continues its reverse motion, the trailing edge of the cam extension closes 154- the switch S2A, and the relay K2 picks up. This corresponds to the "operation when the trailing edge of an original document in the letter copying mode presses the switch SW2 reached during their backward movement. Obxvohl the contacts Open K2-D, wM relay K5 via contacts KJ-B kept excited. The contacts K2-C close, so that a holding path for the relay K4 is also formed after the relay KJ drops out and the normally open Open contacts K3-A.

When the plate moves in the reverse direction, switch SQ1 eventually closes. However, this has no effect on the functioning of the system, as switch SW-D is open. Then the switch SIB closed. Closing the switch also has no effect on the functioning of the system. At this time the contacts K1-D are open and therefore can no current will flow through switch S1B to relay K1 to excite. The switch S1B is only used to control the Relay K1 drops out. This relay is initially energized by the closing of the S1A manual switch.

109845/1336

Finally, while the plate continues its movement in the opposite direction, the switch o> A opens. The Hclain & 5 then falls off. When the contacts Kp-3 xi-llb open, the relay K ^ off. This is the same process as occurs in the letter copy mode. The Heiais LA is still excited, although the normally open contacts KJ- ^ open at this time, since the 'contacts K2-Ü are closed. The heat must remain energized so that the movement of the plate can continue in the reverse direction.

Finally the plate has returned to its original position, v / enn the front edge of the fixed Ifockenn ■ '' ■■ / yo dsn ocruü.-. ter S2A releases. When this switch is opened, the Rolais K2 drops out. The opening of the contacts K2.-C leads to a., The relay K4- drops out. Although the normally closed contacts LA-A close again, the forward clutch K-9 is not energized because at this time the switch bV / -G is open and the contacts K5-B are also open. The opening of the normally open contacts K4 ~ A switches off the clutch K-7, the ^T rollers 6, 17 and 18 stop and the plate comes to a standstill. At the leading edge of the solid liockens 143b is arranged on the plate such that the switch S2A to open when the plate urther ~ j mm (one-eighth inch) has to travel for about v / before / jstartpunkt reaches the output. However, the inertia of the plate keeps it moving until it reaches the starting position. Since it is very difficult to suddenly stop the plate, no attempt is made to do so. Instead, the inertia of the plate is used to advantage. The reverse drive is stopped shortly before the plate has reached its starting position, so that the inertia of the plate then leads to the last part of the backward movement being covered.

Eg it should be noted that during the entire process the time motor 3K1 operates in the same way as is the case when a single copy is made in the letter copying mode. Depending on the length of the original to be copied, the time motor TiH be parked when the switch SW-B is opened. As soon as all relays Ki ₉ K2 and K5 drop out, an .Alternatiweg is set up around the switch SW-B, and the time motor continues its movement from the park position until the switch SW- A opens at the end of a 120 ° movement of the bracket 95. As for the time motor TM2, during the reverse movement of the plate (after the heat K- falls), the contacts KJ-D and K4-D are closed ΠΜ2 is energized, it cannot move the cam 107 counterclockwise past the home position, and a slip clutch (not shown) is provided between the time motor TM2 and the crouch, and one (not shown) ) Stop is provided to prevent the cam 107 sn from rotating counterclockwise past the "single copy" position. Thus, the short-term. Operation of the time motor TH2 has no effect on the functioning of the system.

As already described above, when the book copying rails are inserted, the mirror 65 in the copying machine is moved closer to the exposure window. While this hatred shortens the optical path within the machine (to compensate for the increase in optical path through the glass plate), it also brings the intersection between the optical axis and the scanning window closer to the leading edge of the scanning window. I ^{1 For} proper registration, the "leading edge of the original must begin its movement from a position whose distance from the point of intersection between the optical axis and the scanning window is the same as the distance between the leading edge of the copier

109845/1336

sheet and the intersection between the optical axis and the exposure window when the forward movement of the original begins. If the front edge of the plate in its rest position were arranged at that point on top of the machine which is passed by the front edge of an original document in letter copying mode, which leads to the actuation of switch SW2, it would be obvious that the starting area of the original document to be copied would be of the platen would be "ahead" of the leading edge of the copy sheet and that the leading portion of the original document would be "lost" on the copy. This fact can easily be compensated for by holding the front edge of the plate in the rest position slightly behind the point on top of the machine at which, when an original document is passed in letter copying mode, the switch SW2 is actuated. The mirror 65 is moved about three inches (one-eighth) toward the exposure station when the book copy rails are put on. Thus, all that is required is that the leading edge of the platen, at rest, be about 3 mm (one-eighth inch) behind that point on top of the copier machine at which, when the leading edge of an original document in letter copying mode passes, the Actuation of switch SW2 takes place. If the disk has the entire V / ec traveled to the start position, the leading edge takes dei ¹ actually plate assumes a position, which allows a perfect synchronization, or registration between the original document on the Had and the copy sheet.

As in letter copying mode, when multiple copies of one uxaginal are confused, the dial is turned until the corresponding number appears in the "12 o'clock" position. The switch b'vJ-Ώ is closed. From Fig. P. [1 it can be seen that the switch SW-D was in contact with the container ü ^ l. Although i am a coin-copier; ochlicßon of the retain : rr, otyl by the movement of the had 'cciiie had an effect,

109845/1336

this is not the case with multiple copy operation, since during switch SW-D is closed in this operating mode.

The multicopy operation is identical to the single copy operation during the reverse movement of the disk "up to the point where the trailing edge of the fixed cam closes switch SQI. During the" forward operation of the disk, the fact that switch SQi closes changes the work sy If the system is not, the switches SQI and SW-D are bridged by the normally closed contacts K4-B, which are closed during the forward movement. At the beginning of the reverse movement, the normally closed contacts K4-B open, but at this time switch SQI is also open. As a result, the sequence is the same as in the single copy operation, until the switch S.4I closes during the reverse movement of the plate. In fact, however, there is a slight difference. It should be noted that, in your double copy operation in letter copying mode, when the original starts moving in the reverse direction, there is a short interval during which contacts K3-D are at the same time are closed, at which the contacts KM-D are also closed. The time motor TM2 is excited until the heater KJ picks up, and immediately after it drops. The short excitation interval is not long enough, however, for the switch SW- C closes. Only after the Holais K $ finally drops, the cam Ί07. Is reset. In the single copy operation of the book copy mode, a momentary excitation of the time motor ^f J? M2 (which occurs during the short interval when the Heiais K ~ 5 at the beginning of the Plate backward movement decreases) under no circumstances has an effect, since the crouch 107 does not move counterclockwise past the position shown in Fig. 5 v / can earth. However, it can be moved counterclockwise in four-axis copy mode. .To this

109845/1336

Way, the count is actually reset after each copy. This is how the time-consuming engine begins in multiple-copy operation, the Reset cam 107 when the plate reverses its seal, However, it does not work long enough to close the SW-O switch and thus continue its operation, after the contacts KJ-D open. There is a difference to the single copy process, in which the crouch 107 is at the beginning of the reverse movement of the plate cannot move at all. From this slight difference in the way of working apart from that, xvelcher no difference in the effects the multicopy process is the same how, the single copy process, up to the point in time which switch SQI works when the platform is in reverse Direction is moved in the multicopy flow.)

During the reverse movement of the plate, these are normally closed contacts K4-B open. When the switch Sv ^ l is closed by squatting firmly, otron will flow via the normally open contacts KA - B, x- / elche now are closed, as well as via the switches St & 'i and SW-D and the winding of the Heiais KIi) It is important to note that the containers biB, S2A and SJa both through the fixed Squat .14Jb as well as actuated by the squat extension '54- will. On the other hand, the switch üQ1 only slides on the firm crouching, and the sleep of the switch S ^ I wixxl thus controlled only by the firm crouch.

When the Styl switch closes and the relay is energized Ki picks up the relay K6, the timing clutch K-II is activated, to control the switching on of the exposure lamps, the paper clutch K-12 turns on to control the copy paper feed, normally open contacts Ki-O close, to energize the corona energy supply, etc., as well as it which is 2'all when a single copy is made.

109845/1336

The disk is returned in the same way as it is after a single copy. The switch S1B is closed so that when it opens again during the next forward movement of the plate, the copy paper can be cut by the falling off of the Hclais KI. The containers SpA and S2A are opened, one after the other, as is also the case with the single copy process. The switch BiA is released and the return of the hat stops while the plate still has to travel about 3 son (one eighth inch) before it is in the start position. At the time after which the plate has covered the last three mm (one-eighth inch), the cam 96 has rotated through the angle d2 (see i'ig. 7)> at that point at which the switch SW-O is closed. At this time, the forward clutch K-9 is energized and the disk is moved in the forward direction.

It is to be brought again in memory that, when single-copy sequence, the copy paper feeding starts (during operation of the Holais K1 after the start switch S1A is depressed), and starts to rotate z-.i while at the same time at which the squatting 96th The switch SW-O is not operated by the projection on the cam 96 to start advancing the platen until the copy sheet has reached the exposure window. During the multiple copy sequence, the relay Ki is actuated by the switch S ^ 1, and the copy paper feed is started. At this same time, the clutch K-I1 is energized by the normally open (now closed) KI-B, co that the crouch 96 begins to rotate. Instead of keeping the hat ... 'stationary, as it gocchioht in the single copy process, ν.'υηη the cape sheet begins its Bev.'e ^ ui. ^, The · χ latte pisses her Jcwegiiiii-, · in the reverse direction v.'i'.hrenG

109845/1 3 36

the multicopy process continues. At the end of the reverse However, during movement, cam 96 closes switch SW-O so that forward movement begins. The switch S2A opens, when the plate is moved back, just before the switch SW-O is closed by the cam 96. This allows the plate to return to the start position before the forward clutch is energized. Basically it can be stated that the single copy cycle is repeated over and over again in multiple copy operation will. The only difference is that because switch SW-D is closed, it closes des, switch SQ1 during the reverse movement of the Plate has an effect on the circuit. This effect is to energize the relay K1 so that the Copy paper feed is started before the plate enters the starting position has returned. In this way, as soon as the plate has returned to the starting position is to move them forward without waiting for the copy sheet to "catch up" with them would have to.

During the reverse movement of the disk, the timing motor 1112 causes the disk 102 to reset. When the switch S3A is initially triggered by the rear edge of the fixed cam 14-Jb or by the cam extension 154-, the relay K3 drops out and the contacts K3-D close. At this time, when the normally closed contacts KJ-A close, relay K4 is energized. Although the contacts K4 ~ D close, the relay KJ drops out immediately, the contacts KJ-D open, and the time motor TtiZ does not have sufficient time to turn the cam 107, so that the switch SW-O closes. However, while the plate continues its movement in the opposite direction, the switch SJA finally opens when the leading edge of the fixed cam • '' 43b is below dit-f: era. passes through. At the same time it will

109845/1336

■ Relay Kp off, contacts K3-D close, and the zoom motor ΤΓΙ2 causes that represented by disk 102 Counting is reset, whereby the »switch SW-C closes in exactly the same way as when one is copied multiple times Originals in letter copy mode to ensure that the TM2 timing motor completes its cycle even if the relay K4 drops out at the end of the plate movement in the opposite direction and the contacts K4 - D open before the Dial reset is actually complete.

Eventually the disk is reset to the count "one" (after the penultimate copy is made). the Plate moves forward one more time, as soon as the switch S2A opens, since the relay K2 picks up and the opening of the contacts K2-0 causes the relay K4- to drop out and for energizing the forward clutch K-9 (via switch SW-O). At this point, however, the switch is SW-D opened. Consequently, during the last backward movement of the plate following the production of the last copy, the Closing the switch SQ1 does not excite the relay K1. The plate is simply returned as it is at a single copy sequence is possible without the relay K1 being energized and without the feeding of a new copy sheet from the role. Since the relay KI is not energized during the last return movement of the plate, the normally open contacts K1-B open. Thus, not only is the paper clutch K-I2 without excitation, but The timing clutch K-11 is also not energized. if the latter clutch is not energized, the cam 96 will not rotate. When consequently the plate in its starting position has returned, the protrusion on the crouch 96 does not cause the switch SW-O to close thereafter more. The forward clutch remains without excitation, which is also desirable since the last copy is made.
