The invention is hereinafter described in connection with a one-chip microcomputer or a central computer unit or central unit for controlling the various Operations and operating sections of a copier described.

Referring to Fig. 1, the mode of operation will first be described copier designed according to the invention are described. A thing or a template is placed on a template holder or template table and in -This position is held by a template pressure plate 10. A optical System consists of a lighting unit 101 with an illuminating lamp 9 as well a movable reflection mirror 8, a movable reflection mirror 6, a Objective 17 and two fixed reflecting mirrors 18 and 19. The movable reflecting mirror 3 and the illuminating lamp 9 are indicated jointly in the direction indicated by the arrow A. Direction moves while the movable reflection mirror 6 in the same direction is moved at half the speed of the movable reflection mirror 8, so that a predetermined optical path length is maintained. The picture of over one Slit exposed template is fixed over the lens system 17 and the two Reflection mirrors 18 and 19 on a recording drum 30 with a photosensitive Directed recording material. This means that the original is used by the lighting unit scanned and focused over the slot or directed onto the recording drum.

The photosensitive recording material of the recording drum 30 consists of a photoelectrically conductive layer with a transparent one insulating top layer. A positive charger 12 to which a (not shown) When a positive high voltage is applied to the high voltage source, the recording material is charged positive on. The image of the original is created by means of the optical system described above System with an exposure unit on the recording material of the recording drum 30 directed and discharged by an alternating current discharger 13, which is of a (not shown) high voltage source an alternating high voltage is supplied.

Then the recording drum 30 by means of a lamp 33 is a Subjected to exposure over the entire surface, so that there is an electrostatic Forms charge image on the recording material of the recording drum 30.

In a development station 31, the charge image with toner is in developed into a visible image using a roller development process.

A copy sheet is picked up or separated by a roller 24 and via two first transport rollers 25 and two second transport rollers 28, two control rollers 29 fed at which the copy sheet is stopped. The control rollers 29 are rotated in response to a registration signal, the copy sheet is transported further in such a way that its front edge meets the rear edge or

coincides with the trailing edge of the developed image. The registration signal is issued by a switch RG, which is actuated when the optical System has passed a certain point. A switch OHP generates a signal when the optischesysbem has returned to the starting or resting position.

The copy sheet is in close contact with the recording drum 30 and from a transfer charger unit connected to a positive high voltage source 27 charged, whereby the image on the recording drum is transferred to the Copy sheet is transferred.

Then the copy sheet is by means of a separation roller 26 of the Auf Drawing drum 30 detached and for fixing in one consisting of fixing rollers 4 Heat setting station transported. The fixed copy sheet is used to eliminate the The remaining charge is discharged from an unloader 3 and by means of two discharge rollers discharged into a collecting container 20.

The toner remaining on the recording drum 30 is of a Removed cleaning sheet 11 pressed against the recording drum 30, whereupon the next copying process is started.

The drive system and the sequence of operations will be described in more detail below. When a switch PF of one on the recording drum 30 attached cam is operated, a copy sheet feed signal is generated. The switch DHP generates the drum home signal so that the recording drum 30 can be brought to a standstill in a position in which the connection point between the edges of the recording material with the cleaning sheet 11 can be brought into contact. If a cassette 21 or 22 is empty, receives a photo sensor 23b emits a light beam from a lamp 23a. To capture a delay in the discharge of the copy sheet and an inhibition or one If the copy sheet is jammed, a lamp 2 and a photo sensor 2 'are provided Leerlaur exposure lamp 16 exposes the surface of the recording drum 30, when no image is directed to the recording drum, so that a uniform Surface potential distribution on the recording drum is guaranteed. A Motor 7 drives the fixing rollers 4, while a motor 15 drives the optical system in in the manner described above. A lamp 14 lights the recording material before its exposure, creating a uniform pre-exposure or fatigue of the recording material is achieved. To synchronize the copying processes a pulse generator 36 is provided, which is composed of a joint with the recording drum 30 rotating disk and a photo sensor for detecting a through one of many holes arranged on the circumference or outer edge of the disc Light beam exists.

Control panel and display unit (Fig. 2): An operator can with the central processing unit referred to below as the central processing unit the control panel shown in Fig. 2 connect. According to the above Key groups 21, 22 and 23 entered Input commands or input data the central unit outputs a display via display units 24 to 28. By pressing from numeric keys 0 to 9, the operator can make a desired number of copies set up to the value 99, which is then displayed by means of a display unit 25 will. By pressing a delete key, the display unit 25 is set to the value "0" deferred. When the number of copies required matches that on the display unit 25 matches the number reproduced, the operator presses a "MULTIPLE" key. Pressing this button starts the copier and speaks no longer respond to pressing button 21 and the start button. If the optical System begins to move backwards, the display changes 26 from the value "0" to the value "+1".

If the numerical value displayed on the display unit 26 agrees with the the numerical value reproduced by the counter or the counter 25 is the same The copier is set to "HALT" mode and can be pressed again Address keys.

When the recording drum 30 is completely stopped is, the display of the copy counter 26 returns to the value "0", during the The numerical value reproduced by the counter 25 remains unchanged. Therefore if the same Number of copies to be made from another original presses the Operator press the "MULTIPLE" key again. It should be noted, however, that the Copying process when the value "0" is displayed by the setpoint counter 25 or when the device is switched on of a display element of the display group 24 is not started, even then not when the "MULTIPLE" key is pressed.

When the operator presses a "STOP" key in the multi-copy mode before the numerical value displayed by the copy counter 26 presses that on the setpoint counter 25 displayed number is reached, or if one of the display units in the display group 24 is switched on, the copying process is ended after the previous one or the current copy cycle has ended. It is assumed, for example, that the operator person the stop button is pressed when the setpoint counter 25 has the numerical value "6" and the copy counter 26 display the numerical value "3". The displays then remain unchanged. This means, the counter 25 shows the value "6'l, while the copy counter 26 shows the value" 3 ". In this case, the copier can be accessed by pressing one of the buttons of the Address the input command entered in key groups 21 and 22. When the operator presses the "MULTIPLE" key again, therefore, the copy mode becomes the production of the remaining three copies resumed. After completing a given The copier can restore the number of copying processes or copying cycles to the input commands entered by pressing one of the keys in key groups 21 and 22 speak to.

Independent of the setpoint counter 25 and the copy counter 26 displayed numerical values can be a single copy by pressing the "SINGLE COPY" key getting produced. That is, the operator can use to manufacture a Interrupt copying processes in progress for the desired number of copies from an original, sc that a single copy can be made from another original. Be it For example, assume that the operator will have a displayed counter reading of "6" of the setpoint counter 25 and a displayed counter reading "3" of the copy counter 26 make a copy of another original. The operator pushes then the "STOP" key, places the new original and presses the "SINGLE COPY" key.

This creates a copy while the setpoint counter 25 continues. the value "6" and the copy counter 26 display the value "3". Then the operator puts the original template back on and presses again press the "MULTIPLE" key and three more copies will be made.

If more than one copy is made as part of such an interruption are to be, the operator presses the "INTERRUPT" and "CALL" buttons. It is now assumed that two copies are made by this interruption should, if the target value counter 25 by the value "6" and the copy counter 26 display the value "3". The operator then presses the INTERRUPT button " , whereby the numerical values "6" and "3" are transferred to memory and an interrupt lamp 28 is switched on. The operator then presses the "2" key, whereby the numerical value "2" is displayed on the setpoint counter 25, or she presses the "MULTIPLE" key so that two copies are obtained. Then the operator presses the button "ABRUF", whereby the counter 25 again the value "6" and the counter 26 again display the value "3" and then press the "MULTIPLE" key again so that three Copies are made.

An indicator lamp 27 "DOCUMENT" switched off during the copying process is switched on when the optical scanning of the original to produce the last copy is complete. The operator can therefore immediately use this template remove and place a new template. When the operator presses the "MULTIPLE" key or press "SINGLE COPY", copying will resume.

A lamp 28 "INTERBREAK" is when the "INTERBREAK" button is pressed. switched on, but switched off when the "ABRUF" key is pressed.

If there is a jamming or jamming of copies, immediately a lamp "INHIBITION" switched on and the copier in the operating mode "STOP" ". The numerical value displayed by the copy counter 26 is then dependent on Decreased the number of jammed copies by one or two.

When an obstruction occurs, the operator must open a door of the Open the copier to remove the jammed copy sheet or sheets. the end For this reason, a collective counter is provided, which each copy sheet after Discharge into the collecting container 20 counts. The collective counter therefore does not count any jammed Copy sheets, which also applies to the copy counter 26.

A "REFILL TONER" lamp will come on when there is a supplement of the toner is required. Even if this lamp lights up, copying is in progress not affected by this.

A "REFILL PAPER" lamp is turned on when di: cassette is blank for copy sheets. When this lamp is on, copying is possible cannot be started or it will be interrupted.

A WAITING lamp is kept on until the fuser 4 has reached a predetermined fixing temperature.

As long as the "NVARTEN" lamp lights up, copying can therefore be carried out cannot be started.

By pressing a button "UPPER CASSETTE" or "LOWER CASSETTE" either an upper cassette 21 or a lower cassette 22 can be selected.

Pressing one of these buttons or buttons turns on the other Approved. The format of those in the upper cassette 21 and the lower cassette 22 The copy sheets located are indicated by corresponding lamps in the lamp group 23 displayed.

If the "AUTO" button is pressed, a cassette can be emptied automatic feeding of copy sheets from one cassette to the other only if the other cassette has copy sheets of the the same format as the empty cassette, so that the copier mode also can be continued after emptying a cassette.

Central processing unit and peripheral circuits: In viq. 7 is a circuit diagram of the one-chip microcomputer PPS4 / 1 used in the context of the invention, a product de Rockwell Corporation (for further details see refer to the manual for the PPS4 / 1 computer).

It will now be further discussed in Fig. 6-1, according to the between the in the one-chip microcomputer PPS4 / 1 and the signals used in the context of The control signals used in the invention have the following relationships: DI / oO, DI / o1, DI / o2, DI / o3, DI / o4, DI / o5, DI / o, DI / o7, DI / o8 and DI / o9 = CT1-1, CT1-2, CT2-1, CT2-2, B, E, F, G, I or TC serial output = UL RI / o5, RI / o6, RI / o7, RI / o8, RI / o, RI # o. RI / o and RI / o = A, J, K, L, a, b, c or d INTO = CPoS INTI = STOP PI1 = common connection between the keys "0", "4" and "8", the key "MULTIPLE" and the selection keys "UPPER CASSETTE" and "LOWER CASSETTE", PI2 = common connection between the number keys 1 "," 5 "and" 9 ", the key" SINGLE COPY "and the key "AUTO", PI3 = common connection between the number keys "2" and "6", the "INTERRUPTION" key, the "DELETE" key and the "COINCIDENCE" key, PI4 = common Connection between the number keys "3" and "7", the switch or the "ABRUF" key, the switch or the "INHIBITION" button and the switch or the "FORMAT" button, PI5, PI6, PI7 and PI8 = PF, OHP, DHP and CP.

When the signals PF, OHP and DHP are detected, the one-chip microcomputer becomes switched on and with input signal nals of the value "0".

The "ORIGINAL" lamp is turned on when the J signal is applied to the inverter 601 is applied so that an OR signal is generated. The signal C, which corresponds to A - B, is from the AND logic element 603 receiving the signal A and the output signal of the inverter 602 receiving the signal B. The signal D, the (w E) * A corresponds, is via a combination of the AND logic element 604, the NAND logic element 605 and an inverter 606 are obtained. The inverted signal RG is sent to the inverter 606 fed, the output signal of the inverter 606 and the signal E to the NAND gate 605 are fed. The output of the NAND gate 605 and the A signal is fed to the AND gate 604, which outputs the D signal. The signal H, which is equal to L + E, is received from the OR gate 607, to which the signals L and E are fed.

The numerical display units of the target value counter 25 and the copy counter 26 each consist of seven segments.

The corresponding segments of the four digit display units or light-emitting segment arrangements are associated with each other and with the Output terminals of the driver circuit 608, which is a four-bit Signal from the output connections a, b, c and d for generating the segment control signals or segment driver signals are decoded. The scan lines CT1-Ir CT1-2, CT2-1 and CT2-2 are set and reset in the order in which they are named, which means the numeric display units or light emitting segment arrays in sequence activated or

can be controlled. The ones from the counters at the sixteen crossing points between the scanning lines CT1-1, CT1-2, CT2-1 and CT2-2 on the one hand and the input lines PI1 to PI4 on the other hand formed input signals are in a time-division multiplex connection to the four input signals of the central unit CPU. This means that the signals "0", "1", "2" and "3" are only activated when the Scan line CT1-1 input. In the same way, the signals "4", "5", "6" and "7" is only entered when the scanning line CT1-2 is driven. The signals "8", "9", "UN-INTERRUPTION" and "ABRUF" are only activated when the scanning line CT2-1 entered. The signals "MULTIPLE", "SINGLE-CELL", "CANCEL" and "INHIBIT" become only decoded or evaluated when the scanning line CT2-2 is activated. The signals "UPPER CASSETTE", "LOWER CASSETTE", "AUTO", "COINCIDENCE" and "FORMAT" are only displayed in the presence of the indicating the switched-on state of the exposure lamp Signals E decoded or evaluated. Blocking diodes 19 are used to prevent the Flow of a current in the opposite direction.

As illustrated in Figs. 6-2, 6-3 and 6-4, switches MS13, MS19 and MS21 for recording the size of the copy sheets in the upper cassette is provided, while a switch MS15 makes it possible to determine whether the upper cassette is introduced or not. These switches generate a binary signal with the value "0" or "1", where the consecutive digits correspond from right to left are weighted to the successive power values of 2, that is, correspondingly 1, 2, 4 and 8. Switches MS12, MS20 and MS22 detect the format of the copy sheets of the lower cassette, while a switch MS16 enables the determination of whether the lower cassette is inserted or not. The consecutive digits or numerical values are also weighted according to the values 1, 2, 4 and 8. The coded signals are fed to a multiplexer 609, which in turn controls the upper or lower cassette designating code signal depending on the selection signal OL of the one-chip microcomputer CPU to a decoder 611 which the transmitted Code signal decoded. For example, if the copy sheets are A3 size, only the switch MS15 is closed. As a result, the output signal of the Decoder 611 has the value "0", so that a drive circuit 612 switches on the lamp A3. If the formats A4, U1, U2, B4 and B5 are present, the output signals of the Decoder 611 has the value "2", "3", "4" and "5", respectively.

If the cassette is not inserted, the output signal has the value "8th". If the cassette is not fully inserted, neither switch MS15 the switch MS16 is still switched through, so that the value "8" becomes "1" and accordingly, the output signal of the decoder 611 has one of the values from "9" to "15". As a result, no lamp is switched on (see FIG. 5).

The output signals "0", "2" and "4" are sent to the OR gate 610 so that the "FORMAT" signal has the value "1" when copy sheets with full size are contained in the cassette, but assume the value "0" if Half-size or half-size copy sheets are available.

With the "FORMAT" signal, depending on the size or a sequence of copying operations is selected according to the size of the copy sheets to be used.

The output signals of one of the switches MS13, MS19 and MS21 Switch unit and a switch unit consisting of switches MS12, MS20 and MS22 are fed to a comparison ~ 610, which in turn uses the "COINCINDENCE" signal the value "1" is generated when the two output signals coincide. Of the Value "1" of the "COINCIDENCE" signal means that both the upper and the lower Cassette contains copy sheets of the same size.

When the "UPPER CASSETTE" key is pressed, the central processing unit generates CPU receives the cartridge selection signal UL, which in this case is "0". this has the consequence that a transistor 621 blocks, so that a detector circuit for the upper cassette is energized while the signal UL is "0" from an inverter 623 is inverted and fed to a transistor 622, which by this signal switched through will. This creates a detector circuit for the lower cassette is switched off> switched on or blocked.

When the selected upper cassette is emptied, the resistance drops at a photo sensor CdS 615, so that the potential at the input 6 of a Operational amplifier 613 drops below the potential at terminal 5 and that Output signal of the operational amplifier 613 goes to the value 1, which the signal Represents "STOP". The operation of the detector circuit for the lower cassette in the case of the value 1 of the signal UL is essentially the same as that for above the process described above. If the signal UL has the value 1 and the signal B have the value 1, the transport or separation roller the lower cassette operated while the transport or separation roller for the upper cassette is actuated when the signal UL has the value "0" and the signal B have the value 1.

As can be seen in Fig. 6-4, when the "STOP" key is pressed when the main motor is driven, a flip-flop 617 is set so that the output signal KSTOP has the value "1" because signal A has the value 1. When the main engine is not driven, the signal A has the value "0" and the flip-flop 617 becomes not set. When the main motor is brought to a stop, the flip flop will 617 deferred.

The output signal KSTOP of the flip-flop 617, the output signals of the Detector circuits for the upper and lower cassettes and the non-insertion a cassette in the copier designating signal are the OR gate 618 supplied. The output signal of the OR gate that has the value 1 618 represents the signal fed to the input INTI of the central unit (see FIG. 1) "STOP".

Flag signals in direct access memory (RAM): The following The identification signals or identification bits listed are for setting and resetting of the bits in the memory with direct access (RAM) and thus for control various (lener Processes and work processes provided by the one-chip microcomputer: identification signal 1: (FLG 1) Is set when the "SINGLE COPY" key is pressed, when the "MULTIPLE" key, however, reset. Flag signal 2: (FLAG 2) Used for copy sheets set with full format and reset for copy sheets with half format.

Flag 7: (FLAG 7) Is set when the "MULTIPLE" or "SINGLE COPY" key is used in multiple copy mode be pressed.

Flag 8: (FLAG 8) Is set when the unsubscribe of a copy is delayed or a copy jams (e.g., if a copy has the Detector covered). Flag 9: (FLAG 9) Is set when the recording drum 30 does not return to its rest position when the power switch is closed (the Starting position) and reset when the recording drum is in Their rest or starting position is returned and then their last half turn begins. The flag signal 9 is also set when the "SINGLE COPY" key during the last half revolution of the recording drum is pressed, ulld is reset when the "MULTIPLE" key is pressed. Flag 10: (FLAG 10) Is held in the set state as long as the Number of input pulses has not reached a specified numerical value, and reset when a specified number of input pulses has been counted is.

Identifier signal 11: (FLAG 11) Is used at the last half revolution of the recording drum in the half-format head; operation is set when the optical System has returned to its rest or starting position before the Recording drum has rotated more than 150 ° from the time the optical system has started its backward movement and will reset when the recording drum from the point in time described above Turned 1500.

Flag signal 13O (FLAG 13) Is used when the scanning line is activated CT1-1 set and reset when scanning line CT1-1 is switched off. License plate signal 14: (FLAG 14) Is dependent on the activation and deactivation of the scanning line CT1-2 set and reset.

Identification signal 18: (FLAG 18) If the "BREAKING" key is pressed set and reset when the "ABRUF" key is pressed. License plate signal 19: (FLAG 19) Set when the jam check bypass switch is closed will result in the inhibition check program not being performed, namely not even if a trouble in the transport of the copy sheets occurs. It is here mentions that the escapement check bypass switch can be activated by applying the two Input signals "0" or "1" actuated can be. Likewise a program bypass switch can be provided to prevent the program from executing interrupts or locks when there is no copy sheet and no cassette.

Depending on the state of the flag signals described above or identifier bits, various programs are carried out.

Flow chart of the control sequence: In Fig. 5 is a flow chart of the System shown in the read-only memory ROM of the one-chip microcomputer for performing the operations shown in FIGS. 3 and 4 is. The program sequence will now be described step by step below.

In program steps 1, 2 and 3, after the network has been closed switch and the resulting reset of all circuit arrangements a lamp indicating the size of the copy sheets to be used is switched on, while1 the signal UL in dependence on the pressing of the key "UPPER CASSETTE" or LOWER CASSETTE "in the manner described above, the value" 1 "or" 0 " accepts.

Program step 4 is a subroutine or a subroutine, program steps 261 to 284 (see FIGS. 5 to 6) for operation or actuation the copy counter and the setpoint counter. This subroutine is SUBP executed when the clock pulses are counted or the change in the input signal is awaited. The counters are therefore dynamic with a duty cycle of operated approximately 1/4, so that no flickering occurs in practice.

The program steps 4, 5 and 6 are repeated when the optical System not in its home or home position when the power switch is closed is located so that the optical system is returned to the rest or starting position can be. In program step 7, the optical system is brought to a standstill, when it reaches the OHP position. If the recording drum is not in is in its rest or starting position, program steps 8, 9 and 10 repeatedly to find the signal flHP. When the signal is acquired DHP will be program steps 17, 12 and 52 to 62 are carried out. That is, the recording drum at program steps 55 and 56, one revolution after the detection of the signal DHP executed. The program steps 58 and 59 serve to detect fluctuations in the detection signal by detecting the home position of the recording drum and the signal To prevent DHP generating microswitches. The drum rotation is used to achieve carried out a uniform potential distribution on the drum surface. The fact that the recording drum in the rest position is not at a standstill means that it has not been cleaned and discharged.

This is described in more detail below with reference to FIG. 8. . ^ if the optical system or the recording drum are not in their idle or initial positions are shown by the setpoint counter 25 and the copy counter 26 only shows the value "00". Entering numerical values using the Numeric keys are only possible after the optical system is in its idle or state. Has returned to the starting position and the recording drum is resting or Reached the starting position after performing one revolution. If found becomes that when the power switch is closed, both the optical system and the Recording drums are in their rest or starting positions after program steps 4, 5, 7, 8, 9 and 11 program steps 13, 14, 15 and 16 executed.

Fig. 3 shows a control diagram in the event that two Copies can be produced in half format. The flowchart shall now be explained, when the operator sets the value "2" in the setpoint counter 25 and the Press the "MULTIPLE" key. After program steps 13, 14, 15 and 18 a The follow-up routine following program step 19 is carried out. The program step 19 corresponds to time 1 according to FIG. 3, at which the main engine, the idle exposure lamp and the primary transformer are energized or switched on. The program steps 20 and 21 correspond to the time interval 2 according to FIG. 3, in which sixty singing clock pulses are counted. In addition, the subroutine SUBP is activated during this time interval carried out so that the target value counter 25 and the copy counter 26 are switched on, while sequencing is in progress.

In program step 22, the signal J after counting from sixty clock pulses are emitted, whereby the transformer tap point is selected. The corona discharge alternating voltage therefore increases. The program steps 23 and 24 correspond to time interval 3 according to FIG. 3. They set up a waiting routine on the input of the copy sheet feed signal.

At time 5 according to Fig. 3-2, the recording drum achieves this End of their first half turn. If the copier is in If the "STOP" mode is switched, control is carried out as shown in FIG. 3-2 is shown under 1. The program step 25 according to FIG. 5-1 therefore jumps the program with the value 1 of the signal "STOP" on the program step 51, in which the signals J and K are switched off. The program step 51 corresponds the time 5, while the program steps 52 to 56 correspond to the time interval 6, the Program steps 57 to 59 the time interval 7, program step 60 the time 8, program step 61 the time 9 and program step 62 the time 10 correspond. In program steps 60, 61 and 62 the lamp is switched off, after- which the engine has been brought to a standstill so that a uneven discharge of the photosensitive drum surface due to persistence the recording drum is avoided.

If the device is not in the "STOP "is located, program step 26, in which the signal B is generated, is executed. That is, program step 26 corresponds to time 5, while the program is running from program step 26 to program step 30 corresponds to time interval 11, which waits for the detection of the DHP signal. The course of the program from the program step 31 to the program step 36 corresponds to the time interval 13, which waits for the signal PF to be switched off. At the program step 31, the signal PF is read out synchronously with the clock signals CP to the number of impulses set up to the value 67 must be entered. That is, in the program step 34 not only the state of the signal PF is detected, but also. there is also the Counting the clock pulses. The program step 37 corresponds to the point in time 14. In In this case, the inhibition check consisting of program steps 38 to 45 is carried out for the second copy and subsequent copies. However, since the first copy is established, the identification signal 6 is not set in program step 38, so that the program skips to program step 46. The program steps 46 to 49 correspond to the time interval 15 in which the one started at time 5 Counting of the clock pulses until the value 67 is waited for.

In program step 50, which corresponds to time 16 according to FIG. 3, 67 clock pulses have been counted. The developer moving coil piston, the motor for the forward drive of the optical system and the exposure lamp are energized or switched on. In addition, the pre-exposure lamp is switched on. In the event of the Bt .i tebsart "HALF-FORMAT" is the exposure lamp only during the Ko- pier cycle turned on for the first copy and from the second Copy cycle on switched off. At this point in time, therefore, the program step 65 determines whether the copy sheet is full size or half size, with regard to the first copy it is already established in program step 63, whether the first copy is full size or half size. Because the first copy has the half format, the program jumps from program step 63 to Program step 66 over and the signal G is emitted.

From the time 16 on, the counting of the clock pulses continues up to the Value 87 a. The subroutine for waiting for the switch or signal to switch off OHP is formed by program steps 67 to 70, which correspond to time interval 21 according to FIG. 3 correspond. The time at which the OHP switch is turned off, is denoted in FIG. 3 by time 31, which corresponds to program step 71.

In the case of the "HALF FORMAT" and "HALF FORMAT" operating modes, becomes at this point in time the inhibition test was carried out.

Since the first copy is being made, the program jumps to one another from the state of the identification signal 6 from the program step 73 to the program step 81 over. The inhibition check routine in the case of the "HALF FORMAT" copying operation is formed from program steps 72 to 80. In program steps 81 to 82, which correspond to the time interval 27 according to FIG. 3, is the count of the clock pulses waited up to the value 87. In program steps 84 and 85, the time interval 29 according to FIG. 3, 105 clock pulses are counted. During the program step 86 to 101 and program step 112, 105 clock pulses have been counted. These Program steps correspond to time 30 according to FIG. 3, at which the movement occurs of the optical system reverses. As can be seen in program steps 86 to 91, at this point in time it is determined whether the selected cassette is emptied or not. When the cassette is empty (program step 86) will determined whether the "AUTO" key has been pressed (program step 87) and also It is necessary to determine whether copy sheets of the same size have been inserted or not. After program step 89, the signal is in program step 90 or 91 UL surrendered or terminated. In addition to the case of a cartridge emptying in program step 86 the "STOP" signal has the value "1 t when the" STOP "is pressed or the cassette has been pulled out of the device. In this In the event of a change, the signal OL changes once, but is repeated in program step 101 determines whether the "STOP" signal has the value "1" or "0". At the time the return of the program to program step 13 of the key reading routine after the program step 112, the signal UL is thus again in the original State reset.

Since the point in time 42 according to FIG. 3 is the point in time of the reversal of movement of the optical system, it is determined in program step 92 whether the Copy sheet is full size or half size. If the copy sheet has the Has full format, the program jumps from program step 93 to that with the full-format operating routine beginning program step 190 (see FIGS. 5-4). However, since a copy is now being made in half format, the program goes to Program step 94 over. In program steps 96 to 102, the count becomes CT2 increased by the value 1 and compared with the set numerical value CTi. If the If values CT1 and CT2 coincide, the program jumps to the program step 112 to the "STOP" operating mode. The values CT1 and CT2 are in memory words with the addresses 10, 11, 1 2 and 13 stored in the memory with direct access RAM.

If there is an inhibition in the "STOP" operating mode before time 42 3 occurs, program step 112 continues with the routine for the last half turn.

Otherwise, a routine of program step 103 until carried out to program step 111. That is, if the copier by the time 30 of the reversal of movement of the optical system up to (in Fig. 3 by the reference number 3) time when the signal PF is applied to the "STOP" mode "is set, the signal J is ended (program step 106) and the program jumps to the routine beginning with program step 134 for the last half Revolution over when 150 clock pulses have been counted. The program steps are executed in the order 103, 104, 105, 106, 107, 109, 103, 104 and 134.

If the copier is not set to the "STOP" mode the steps 103, 104, 105, 107, 109, 103 ... are repeated until the signal PF is emitted (interval 16 according to FIG. 3). When the signal PF is issued is, the program steps 103, 104, 105 and 108 are executed and the flag 5 is set (which indicates the start of the second copy cycle). Then it returns Program back to program step 26, in which the transport roller signal B is delivered. This corresponds to time 17 according to FIG run through control operations shown in FIG. 3 from 5 to 16.

Below is the routine for reversing the optical system (F) and the inhibition check routine, both in the on the second copy cycle The following copy precautions are included: Program steps 32 to 36 of the second copy flow correspond to the time interval from the point in time of Termination of the DHP signal up to the point in time of the termination of the PF signal (the Time interval 20 according to FIG. 3). If the optical system during this time interval has returned to its rest or starting position, the signal F is through program steps 35 and 36 are ended. Because the motor of the recording drum is not is synchronized with the motor for the backward movement of the optical system, changes that of the optical system for return to the rest or home position needed Time from one operating section to another. The from program steps 29 and 30 existing routine and the routine consisting of program steps 48 and 49 are therefore in the time interval (corresponding to program steps 27 to 30) 18 and the time interval 22 (corresponding to program steps 46 to 49) according to FIG Fig. 3 inserted to terminate the signal F when the optical system is in its Rest or starting position has been returned.

The inhibition check of the first copy is carried out by determining whether the first copy reaches detector 2 (where the COPS signal has the value 1 at Reaching) when the signal OHP at the Vorvorsteigunq the optical System (signal E on) is switched off in the second copy cycle. That is, the Determination takes place at the point in time 25 according to FIG. 3. This is confirmed by the Program step 72 to program step 80 according to FIG. 5-2 is checked. If the first copy does not arrive at the detector, the program steps in iier Sequence 72-73-74-75-76-77-78-79-80 executed so that the flag signal 4 is set. That is, the fact that the copy has jammed will saved. At the same time, the counter reading of the copy counter or the signal CT2 decreased by the value 1 and the inhibition sol eiioids iynal released, so that the inhibitor switch is closed, whereby the high voltage sources are switched off will. When the switch is closed to bypass the escapement check and this command has been read in at key entry routine 13 the program steps 77 to 80 corresponding to the state "1" in the program step 75 detected license plate signal 19 executed light. This means that the Device can perform a test run without feeding a copy sheet. The activated signal I is in the (corresponding to section 32 according to FIG. 3) Program step 83 ended or switched off.

In Fig. 3 is only the timing for production from two copies shown. If more than two copies are made, the Inhibition check of the first copy if the signal PF is in the third copy cycle is switched off, as shown in program steps 38 to 45. This means, if the first copy jams, the program steps are in sequence 38, 39, 40, 42, 43 and 45 carried out, after which the main program on the with the program step 135 begins, the routine is skipped for the last half revolution. When the flag signal 18 is set, so that the fact of inhibition in the event of the copy mode HALLFOPxMAT is saved, the third copy cycle is already has been started so that the copy count signal CT2 is decreased by 2. However, if no inhibition occurs (that is, if the signal CPOS has the value "0" the program steps are carried out in the order 38, 39 and 42, so that the signal TC to increase the count of the collective counter utn the value 1 is generated. In program step 50, the signal TC is ended or switched off.

It is now assumed that at time 25 according to FIG. 3-2 the inhibition check is complete and the optical system has reached point 34 at which im second Kt.pier cycle the movement of the optical system has to be reversed. The signal CT2 increased by the value 1 during the erogram step 99 then shows in program step 102 coincidence with the signal CT1, so that the identification signal 3 is set. That is, the coincidence between the signal CT1 and the signal CT2 is saved. The routine beginning with program step 112 is then carried out executed for the last half turn. The program steps 113 to 133 correspond the interval 35 according to FIG. 3, in which 150 clock pulses are counted. Simultaneously the program waits for the return of the optical system in its rest or mode. Starting position from (OHP). When the optical system has returned to its original or rest position is ends the signal F (in program steps 115 and 116) and at the same time the subroutine consisting of program steps 117 to 126 becomes SUBI started to check jamming or jamming of the first copy and the flag signal 11 is set. After the flag signal 11 is set, the inhibition check routine consisting of program steps 118 to 125 is omitted through program step 117, even if the optical system is is in its rest or starting position.

This point in time corresponds to the point in time 36 according to FIG. 3.

That is, the inhibition check will be during the last half Rotation only made when the optical system is in its rest or starting position is returned. As in the case of an inhibition or jamming of the first copy the switch to bypass the inhibition check is not closed the program steps in the order 117, 118, 119, 120, 121, 123, 124, 125 and 126 executed and the flag 8 set, so that the presence of an inhibition and the copy count signal CT2 is reduced by the value 2. aside from that the escapement solenoid signal I is generated (see reference number 4 in FIG. 3). Since that Flag signal 11 has been set, the program jumps to the one from the program steps 117 to 127 existing routine.

If there is no inhibition and the optical system returns to its original or rest position is returned, the program steps are in the order 117, 118, 119, 120, 122 and 126 executed and the collective counter signal TC output.

The program steps are used up to the counting of 150 clock pulses 127 to 133 existing key entry start routine continuously executed. Only if the Routine for the last half revolution as a result of a coincidence between the. Signals CT1 and CT2 or in the "SINGLE COPY" mode is the Entering an input command by pressing the "MULTIPLE" or "SINGLE COPY" key possible from time 34 according to FIG. 3-2. That is, at To press With the "MULTIPLE" key, program steps 127, 128, 129, 130 and 133 are carried out. If the "SINGLE COPY" key is pressed, the program steps in the Order 127, 128, 129, 131, 132 and 133 executed. When pressing the "MULTIPLE" key Therefore, the flag 9 is set to the value "0", while the flag 7 is set to the value 1. When you press the "SINGLE COPY" key, both the identification signal 9 and the identification signal 7 are set to the value i. As described above, the flag 9 indicates the modes Multiple copying or single copying while the flag signal having the state "1" 7 indicates that the command to restart or restart is during operation for the last half turn has been obtained.

In program step 134, which corresponds to time 38 according to FIG. 3, 150 clock pulses have been counted. Program steps 135, 136 and 137 are intended to protect the copier, otherwise from the temporal changes the sequence of movements of the optical returning to its rest or starting position System is adversely affected.

The program steps 138 to 140 correspond to the time interval 40 according to Fig. 3-3, in which the clock pulses from the time 38 on bts to the value 38 can be counted. If 38 clock pulses have been counted at time 41 according to FIG. 3-3 is the signal generated as a result of the inhibition test at time 36 I or TC (in program step 141) ended or switched off. In addition, the Inhibition check of the last copy in the program steps 142 to 149 is carried out. That is, if none before this point in time Inhibition has occurred and the switch to bypass the inhibition check has failed has been closed, the inhibition check is started.

If the last copy jams, the signal I is generated so that the Flag 4 is set and the counter reading of the copy counter increases by the value 1 be reduced. It should be noted, however, that in the case of the SINGLE COUPLE " the counter reading is not reduced (see program step 147).

In the program steps corresponding to the time interval 42 according to FIG. 3-3 150, 151 and 152 are counted 60 clock pulses. If at time 153 sixty clock pulses have been counted, the previously generated signal I at time 43 according to. 3-3 finished. From program 154 to program step 156, the program waits for the Return of the recording drum to its rest or starting position during the Time interval 44 according to Fig. 3-3. That from program steps l40, 152 and 156 The existing SUBH subroutine enables the input command to be entered using the "MULTIPLE" or "SINGLE COPY" key during the time interval between the time 34 and the time 45 according to FIGS. 3-3. When the optical system is in its rest or starting position OHP has returned (time 45 according to FIG. 3-3), the motor signal A is ended or switched off in program step 157. Of the Program step 158 corresponds to the time interval 46, during the program step 159 corresponds to the time interval a. If before that time there is a delay or The program proceeds from program step 160 or 161 to the jam removal routine beginning with program step 182 above. If there is no delay or inhibition and no instruction to If the inhibition check is skipped (see program step 162), the inhibition check is carried out the last copy carried out. If no inhibition is detected, the signal will TC generated and terminated in program steps 164, 165 and 166. When the signals CT1 and CT2 have coincidence, so that the "STOP" operating mode is entered, the copy counter is cleared in program steps 167 and 168. When the button "MULTIPLE" or SINGLE COUPLE "not pressed for the last half revolution during operation has been, the program steps 169 to 175 are carried out and the program returned to the key entry routine beginning with program step 13. If the "MULTIPLE" key has been pressed, program steps 169, 170 and 171 executed, while in program step 173 it is determined whether the setpoint counter displays the value "0". If the setpoint counter shows the signal "0", this is reversed Program after execution of program step 175 to the one with the program step 13 starting key input sequence back. That is, the copier speaks during of operation for the last half revolution not on pressing the "MULTIPLE" key at.

If the setpoint counter does not show the "0" signal, the program steps are 173 and 174 are executed and the program jumps back to program step 19 over, which starts another copy cycle. When the "SINGLE COPY" key has been pressed, program steps 171, 170, 172 and 174 are executed and the program jumps back to program step 19, so that a copy cycle is started in single copy mode. If an inhibition is detected, the signal is I is generated and the counter reading of the copy counter is reduced by the value 1 (see program steps 163, 176, 177, 178, 179, 180 and 181). However, in the single copy operation, the reduction becomes of the counter reading of the copy counter by the value 1 not carried out.

The inhibition release routine consists of program steps 182 to 189. During program steps 182 to 184, the activation of a reset button Waited for the release or deactivation of the inhibitor switch by an inhibitor mechanism (see Fig. 9-2) was closed, which in turn is locked by the signal I. had been. If the inhibitor switch is turned off, the program step 182 starting program steps are executed, i.e. the program waits for this pressing the "MULTIPLE" key again when the "MULTIPLE" key has been pressed was before the copy cycle started. Similarly, was- tet the program starts again pressing the key "SINGLE COPY" if this key is before Was pressed to start the copy cycle. If you press the "MULTIPLE" button again program steps 185, 186, 187 and 188 are executed, whereupon the Program skips to program step 19, so that only the remaining Copies are made. A different combination of program steps than that The combination described above will not be accepted under any circumstances.

Referring now to FIGS. 4, 5-4 and 5-5 the copy mode "FULL SIZE" can be described. The in Fig. 4-2 at the reference number 1 beginning and ending with reference number 3 correspond to the essentially those according to FIG. 3, so that a more detailed explanation is not necessary is. The "FULL FORMAT" copy mode differs from the "HALF FORMAT" copy mode from the point in time 30, at which the optical system is in "HALF FORMAT" copying mode reverses its movement. This point in time 30 corresponds to program steps 86 to 92.

The format is determined in program step 92, whereupon the Program from program step 93 to that beginning with program step 190 Skipping routine. The routine consisting of program steps 190 and 191 causes the optical system to move beyond the reversal point in the case of the mode of operation "HALBFORMAT" is moved out and the count of 150 clock pulses is awaited. The program steps 190 and 191 therefore correspond to the time interval D according to FIG. 4-2. When 150 clock pulses have been counted, the movement is reversed optical system at time e according to FIG. 4, the program steps 192 to 198 corresponds. At the reversal point or program step 192, the signals E and G terminate while signals F and L are being generated. When the operating mode "MULTIPLE" is determined in program step 193 and by program steps 194 and 195 no inhibition is determined, the counter reading is made in program step 196 of the copy counter 26 to the Value 1 increased. If in the program step 197 the counter reading of the copy counter 26 or the signal CT2 coincidence with the The program steps become 199 to 231 are carried out and program step 232 is thus reached. When in operating mode "STOP" there is no coincidence, program steps 199 to 231 are also executed executed so that the program reaches program step 232. If with a other operating mode apart from the operating mode "STOP" no coincidence of these values or Signals occurs, the program jumps from program step 231 to the depot program step back 200. That is, at time 30 the program has two program changes to advance to program step 200 or program step 231.

The sequence after program step 231 will first be described are if in program step 193 the operating mode "SINGLE COPY" is determined, an inhibition is determined in program steps 194 and 195 and in program steps 197 and 199 found the coincidence between the signals CT1 and CT2 or the Coincidence not determined, but rather in program steps 197 and 198 the STOP mode have been detected. That is, the point in time e according to FIG. 4 can can be viewed as shifted to the point in time n according to FIG. Since the copy counter 26 shows the value "1", it can be assumed that the time e is only in the "STOP" operating mode has been shifted to time n and the following Program sequence is executed.

Since the first copy is being made, the program step is 200 the following program sequence is described after the counter reading of the copy counter has been increased by the value 1. The program steps 200 and 201 correspond to this Interval f according to FIG. 4-2, with 38 clock pulses being counted at time g for which the inhibition check is used as in program steps 202 up to 208 to take is. This inhibition check will too carried out when the switch is opened to bypass the inhibition check is as indicated by program step 203. When the If the copy is delayed or the copy jams, flag 4 is set, the solenoid signal I is generated, the counter reading of the copy counter is reduced by the value 1 and the signal J terminated or switched off. These control processes are shown in Fig. 4-2 shown. The copy count signal CT2 is not decreased if in the program step 206 the operating mode "SINGLE COPY" is determined. In the time interval h According to program steps 209 and 210 corresponding to FIG. 4, 112 clock pulses are generated counted. When the 112 clock pulses have been counted at time i, that becomes from time g on generated signal I ended or switched off. In the program step 212 it is established at time g whether an inhibition has occurred.

If an inhibition is detected in program step 212 (the identification signal is set to the value 1), those starting with program step 213 are Program steps with the time shown with reference number 2 according to FIG Control executed. At time i or

in program step 214 the signal K is ended and the program waits during program steps 214 and 215 for the optical system to return to its starting or rest position (OHP). This interval corresponds to the time interval 7 'according to FIG. 4. When the optical system at time 8' in its output and Has returned to the rest position, the signal F is terminated. When the recording drum in program steps 216, 217 and 218 (which correspond to the time interval 9 'according to FIG correspond) to their rest or starting position is reached during the program steps 220 and 221 the switching off of the signal DHP (during the time interval 11 'according to FIG Fig. 4) waited. The program then waits again for the recording drum to return in their resting or starting position and finished then the copy operation.

If no inhibition has been determined in program step 212, is during the program steps corresponding to the time interval j according to FIG 223 and 224 the return of the optical system to its rest or starting position OHP waited. When the optical system has returned to its rest or starting position is, the signal F is terminated or switched off (at time k according to FIG. 4) and in program steps 226 and 227, the presence of the signal PF (at Time interval 1 according to FIG. 4) waited.

The signal PF is present at time 17 according to FIG. 4. If that Copier at this point in time or program step 228 in the operating mode "STOP" is, the program advances to program step 229, in which the Signals J and K are terminated. In program steps 257 to 260, the termination of the signal PF waited. When the DHP signal is detected after one more revolution of the recording drum, the copying operation is ended.

If the "STOP" operating mode is not determined, the program step 230 the identification signals 5 and 6 are set and the program jumps to the program step 26 at the beginning of the second copy cycle. The timing of taxation from the reference number 17 according to FIG. 4-3 with reference number 32 is therefore similar to the control curve of FIG the reference number 17 to the reference number 32 according to FIG. 3. In the second copy cycle however, if an inhibition check is carried out for the first copy at time 21, as indicated by program steps 38 to 45.

If the copy is stuck, the program continues after executing the program steps 38, 39, 40, 42, 43 and 44 to program step 217. First are the signals J and K terminated, secondly the indicator signal 8 set and thirdly the counter reading of the copy counter is decreased by the value 1. After the program on the program step 217 is passed, the rotary motion of the recording drum until the DHP signal is detected, at which point the copy cycle is interrupted or is terminated.

The operations from time 17 are in the second copy cycle at time 34 similar to that of the "HALF FORMAT" mode. This means, the copying processes differ from one another from time 34 or the program step 92. The time interval n shown in FIG. 4 corresponds to the program steps 190, 191 and 132. At time n, the movement of the optical system is reversed and the signal CT2 = CT1 is detected in program step 197 so that the signal J terminated or shut down, thereby reducing the AC charge is effected.

The program then goes to program step 232 for execution the routine for the last half turn.

The program steps corresponding to the time interval o according to FIG 232, 233 and 234 are used to count 38 clock pulses. If at time p according to Fig. 4 38 clock pulses have been counted, the inhibition check for the last copy carried out, as shown in program steps 235 to 241 is. That is, if it is determined in program step 235 that there is no inhibition has occurred and it is determined in step 236 that the jam check override switch has not been closed, the inhibition check is carried out. Will however an inhibition is detected, the inhibition solenoid signal I is generated and the The counter reading of the copy counter is reduced by the value 1 in program step 240.

In the case of the "SINGLE COPY" operating mode, the counter reading of the copy counter is but not reduced.

The program steps 242, 243 and 244 correspond to the time interval r according to FIG. 4 for counting 60 clock pulses.

If at time s according to FIG. 4 60 clock pulses are counted been are, the signal I generated from program step 241 is terminated. If at the time t according to FIG. 4 52 clock pulses are counted in program steps 246, 247 and 248 have been, in program step 249, the preload signal K at time u according to Fig. 4 switched off.

The program waits during program steps 250, 251 and 252 the return of the optical system to its rest or starting position OHP (the Program steps 250 to 252 correspond to the time interval w according to FIG Time x according to FIG. 4, which corresponds to program step 253, becomes the signal F finished. The program then waits during program steps 254 to 256 (the correspond to the time interval y according to FIG. 4) the activation of the cam generated signal PF. When this signal PF has been generated, the program waits during program steps 258 to 260, the termination or switching off of the signal PF off. After the signal PF has been switched off and the recording drum has performed another rotation and returned to its rest or starting position (see program steps 154 to 156 and reference number 41 according to FIG. 4) the copy cycle is interrupted or ended.

The one consisting of program steps 234, 244, 248, 252, 256 and 260 Subroutine SUBH is provided in such a way that after time n the input of Input commands using the "MULTIPLE" or "SINGLE COPY" key.

The key entry routine illustrated in Figures 5-7 is one of ordinary skill in the art understandable in and of itself, so that a more detailed explanation is dispensed with will.

Before copying starts, an interrupt copier operation can be performed successive actuation of the interrupt key, a number key and the Start key while the interrupt copier operation starts after the start of the Copying by pressing the stop key, the interrupt key, a number key and the start button can be carried out in this order.

The function of the "INTERRUPTION" key is essentially be the same or similar to the "STOP" key.

That is, when you press the "INTERRUPT" key, the copier will turn off set to last half turn operation. In detail, when you press the "INTERBREAK" key, the flip-flop 617 (see Fig. 6-4) is set and an interrupt input signal until this has been read into the central processing unit CPU. When copying in Interrupt operation is carried out, the counter content of the setpoint counter 25 and the copy counter 26 in two registers of the RAM with direct access transferred, whereupon the desired number of copies on the setpoint counter or setpoint display 25 can be set. The program is then executed via the key entry routine. When the "AB-RUF" key is pressed after copying is complete and setting the copier to operate for the last half revolution is pressed, the memory contents of the registers are transferred to the memory words with the Addresses 10 to 14 are transferred to their memory RAM with direct access and then the target value counter or the target value display 25 and the copy counter or the copy display 26 supplied. Then, after pressing the "MULTIPLE" key, the remaining copies getting produced.

Alternatively, the main program or framework program can contain instructions also implied that in the operation for the last half turn or if the device is brought to a standstill after pressing the "INTERRUPT" button the counter contents of the setpoint counter 25 and the copy counter 26 automatically back into the specified memory areas of the RAM memory with direct access is stored so that the numerical values can be retrieved later from the setpoint counter 25 and the copy counter 26 can be reproduced. This can also be done manually Press the button "S'l'OP" done.

In Fig. 6-7 a circuit diagram is shown, according to that when pressing the "INTERRUPT" key puts the copier into interrupt mode and when the motor is stopped or at a standstill (A = "0") the data call "ABRUF" is carried out will.

6-8, capacitors 48 and 51 produce both leading edges and trailing edge of the signal A each have a pulse, while a capacitor 49 after the interrupt copy, a pulse on the trailing edge of the pulse signal A generated.

A flip-flop comprising logic elements is activated by the "INTERRUPTION" key set. If the point in time of this setting is before the start of copying, is an interruption copy can be made immediately, while in the event that that the time of setting falls in a copy period, the interruption copy can be made after completion of the copy. Pressing the button "STOP" is used to prevent interruption copying and then effects the data retrieval ("ABRUF"). Do not use any other button except the "STOP" button the "ABRUF" function can be achieved. The output signals from PI3 and PI4 are after switched off one second. An operating mode "CASSETTE OPERATION" can be activated by the the "INTERRUPTION" key.

In Fig. 9, the escapement release mechanism is shown. That is, Fig. 9-1 shows door switches DS which turn the power source on and off when a cover and a door can be closed and opened, thereby making the operator safe is guaranteed when she removes the jammed copy from the copier. In Fig. 9-2, a mechanism is illustrated which, upon energization of the inhibition solenoid turns off the power source for the fixing device and the DC high-voltage source. When an inhibition occurs, the solenoid SL is energized, so that a lever 92 with one Projection 91 is raised and thereby a previously of the Projection 91 held or brought to a standstill release lever 93 by the Spring force of a spring 96 is pivoted about its pivot pin, creating a micro-cup 94 is opened. This has the consequence that the copier is switched off and comes to a standstill is brought. After removing the jammed copy, the operator squeezes a reset switch 95, which in turn moves the release lever 93 into its in the Fig. 9-2 presses the operating position shown on the left. Before getting a copy, however not jammed, the main motor is kept on until the copy is ejected has been.

The switch 93 is connected as shown in Fig. 9-3.

It thus becomes a copying method and an image forming apparatus for Proposed implementation of the method in which the copying processes as a function can be controlled by a program sequence or a program sequence. The image forming device has an input unit for entering copy instructions and scanning signals, a control unit for controlling image generating devices in dependence from the output signals of the input unit as well as connected to the control unit logic circuits for controlling the associated units or image generating devices on.
