Referring now to Figs. 1-A, which shows an exterior view of a copying machine and an operating unit thereof, namely, an embodiment of the image processing system of the present invention. This system is basically made up of two units, namely a reader A and a printer b. These units are mechanically and functionally separate so that each of the units can be used alone. The units are connected to each other by means of a cable or the like. The reader A is equipped with an operation unit A-1.

Fig. 1-B is a sectional view showing the structure of the copying machine and the operation unit thereof according to the embodiment of the image processing system. A document or print text is placed face down on a platen glass 903 , as viewed from the front, the adjustment base is the left inner area. Reflected light from the template illuminated by a fluorescent lamp 902 is deflected by means of mirrors 905 and 907 and focused by means of a lens 906 on the surface of a charge coupling device (CCD) 901 . The mirrors 907 and 905 are moved at a speed ratio of 2: 1. This optical unit is moved from left to right by means of a DC servomotor under constant speed phase locked loop control. During the lighting of the original during a forward movement, the speed of movement is 180 mm / s, while the speed of movement in a return is 468 mm / s. The resolution of this sub-scan is 16 lines / mm. Original sizes from A5 to A3 can be processed. A5, B5, and A4 size originals are placed lengthwise, while B4 size and A3 size originals are laid laterally or laterally. According to the original formats three reversal points are provided for the return of the optical unit. A first digit (for the A5, B5 and A4 formats) is 220 mm away from the document reference position, a second digit (for the B4 format) is 364 mm away and a third digit (for the A3 format) is 431.8 mm away.

On the other hand, according to the orientation of the Template the width of the main scan up to 297 mm (what the width of the A4 size originals). For a resolution of the range of this width to 16 lines / mm are at the charge coupling device 4752 (= 297 × 16) bits required so that as charge coupling device tion two charge coupled line sensors with each 2628 bits are used, which are parallel to each other be controlled. This results from the conditions a resolution of 16 lines / mm and a scan speed of 180 mm / s (the storage time of La corresponding to the main coupling period de T = 1 / v × n = 1/180 × 16 = 347.2 μs. The transmission speed or transmission frequency of the charge stop lungsvorrichtung is then f = N / T = 2628 / 347.2 μs = 7.569 MHz.

Next, the printer set in the reader will be described with reference to Figs. 1-A and 1-B. An image signal processed in the reader unit in bit-serial form is input to a laser scanning optical unit 925 in the printer. This unit includes a semiconductor laser, a collimator lens, a polyhedron rotating mirror, an F-Θ lens, and a reverse optical correction system. The image signal from the reader is applied to the semiconductor laser, in which the signal is then converted electro-optically; the thereby emitted by the laser laser light is converted by means of the collimator lens in parallel light and directed to the polyhedron rotating mirror, which rotates at high speed; As a result, the laser light passes over a photosensitive material 908 . The polyene rotating mirror operates at 2600 rpm. The scanning width of the light is about 400 mm, while the usable width for the image is 297 mm, corresponding to the width of the A4 size sheet. As a result, the frequency of the signal applied thereto to the semiconductor laser is about 20 MHz (NRZ). The laser light from this unit is directed through a mirror 924 on the lichtempfind Liche material.

This photosensitive material 908 example, consists of three layers, namely an electrically conductive layer, a photoconductive layer and an iso lierschicht. It is therefore provided a processing unit that allows the creation of an image by means of the three layers. In the processing unit, 909 is a pre-discharger, 910 a pre-discharge lamp, 911 a primary charger, 912 a secondary charger, 913 a total illumination lamp, 914 a developing device, 915 a paper feed cassette, 916 a paper feed roller, 917 a paper feed guide, 918 a registration feeder Stop roller, 919 a transfer charger, 920 a detachment roller, 921 a transport guide, 922 a Fixiervorrich device and 923 an output table. The speed of the photosensitive material 908 and the conveyor system is 180 mm / s, and thus is the same as that in the reader in the leader. Therefore, the copying speed of the combination of the reader and the printer for A4 size copies is 30 sheets / min. The printer is provided on the front side with a release tape for releasing a copy paper which adheres to the photosensitive material and the drum, respectively; therefore, an image area corresponding to the width of the band is lost. If an image signal is supplied also for this area, the area is developed and the release tape is contaminated with the toner in the developer, with the result that subsequent paper leaves are also polluted. Therefore, the design is such that in advance in the reader of a print output signal that portion of an electrical image signal is cut off, which corresponds to the Ablöseband- width of 8 mm. Further, if toner adheres to the front edge of the copy paper, the paper is wound on the fixing roller in fixing the toner, so that an inhibition occurs. Therefore, to prevent the adhesion of the toner, a portion of the electrical signal corresponding to the paper leading edge having a width of 2 mm is also suppressed.

In this device according to the embodiment have the image information is the form of electrical signals and there are the reader and the printer at separate Functions separated from each other, so that Bildinforma tion transmission between these units allows becomes. If at a communication link the reader and the printer can be used as a unit or The reader alone can be used on the reader Communication module can be installed while when using the printer alone, the module can be attached to the printer; for a local  In-house messaging can do this Units are looped. For one External messaging can be at the Loop a branch circuit (as an interface between public and the local loop). Furthermore, an electronic letter delivery system between a main building and outbuildings the connection of cable networks with copying units be formed.

Next, these functions will be described by means of the copier and the associated control unit according to the embodiment of Bildverarbei system can be achieved. In addition to the usual Chen function as a copy machine has this facility still different kinds of other functions like the changes tion of the reproductive ratio or reproduction Scale for either zooming in or out the copy picture format, the output preparation for the picking out or omission of any area a template and automatic capture of the format and the location of an auto-change template the reproduction scale or the output preparation the template. These functions for processing the Images on a template are commonly referred to as "image ver In addition to this, the device not only by means of the connected Printer makes a copy of a read template image but also via a data transfer tax unit (CCU) the template image to other printers transfer. Furthermore, with the existing printer It is possible to receive template images from be sent to another reader. Such Function is called "image transfer function". Any chosen function or functions according to The above description can optionally be in six  Presets are stored. The storage unit can be chosen by the user at will and will also turn off the power maintained. Such a function is called Pre-selection function called. Furthermore, the facility has the function of an automatic exposure for the Shadowing the background of the template and the function Tinting processing for the output of a Image with tint or gradation such as a photograph with high fidelity. These Functions are commonly referred to as "image quality processing If one grasps the above Designs together, as are image processing radio tion the following five functions: As Reproduction scale change is the real-format repro production (with the reproduction scale 100%), the choice a fixed reproduction scale (format choice), the stepless reproduction scale change (reproduction scale selection (R.R. Sel) from 50 to 200%) and from each other independent reproduction scale changes in the Directions X and Y provided (R.R.C.X / Y in the main scanning direction and the sub-scanning direction).

Image reversal functions are an original image reproduction (Original) and a negative / positive reverse image re-image (NEG / POS).

However, the latter two functions change automatically table to automatic full page normalization (A.F.P. S.), whereby the attitude of any other functio is impossible. Furthermore, a white frame (white) a black border (black) and an automatic Template position detection (DPAD) provided. Here you can  but at the same time the independent scale change R.R.C., the image reversal, a shift and special R.R.C. Be assigned functions.

As shifting functions are omitting a Shift, determining a shift destination location (SSD) moving into a corner (COR) and the Move to center (CENT) provided. As a special RRC functions are omission of dialing (NON-SEL), an automatic fixed-scale standardization (AFRS) and automatic full-page normalization (AFPS) is provided, where in the latter two functions no other RRC or scale change function are determined can. The functions of the shift and the change on a special scale are only effective if the white or black framing and the automatic Template position detection are selected. To the image transmitter functions include local copying (ordinary Copy), Send (for sending the template image to another printer via a switching control unit (CCU)) and receiving (for receiving a template image from another reader over the Switching Control Unit (CCU)).

The preselection functions are the Save (for the Abspei chern in a preselection key) and reading (for the Reading the content stored for the preselection key) intended. The pre-selection part also has a reset Function for returning to any normal operation art.

As picture quality processing functions are the automatic exposure (AE) and the tinting Preparation provided.

In the embodiment of the image processing system according to the invention, the display device is a liquid crystal display device. FIG. 3 is a detailed view of the display device 202 and the function keys 201 . Each unit of the display device 202 is a liquid crystal display unit in which 5 × 7 dots are arranged in a matrix of 32 characters. The display device 202 can be arranged flush with the function keys 201 .

Fig. 4 is an enlarged view of a (dashed line bordered) character position in Fig. 3. In Fig. 4, 1 is a 5 × 7-point section of the liquid crystal display unit designated, while 2 is a 5 × 1 Dot section for displaying an underline. The number of dots and characters can be increased if necessary.

Fig. 5 is a block diagram of the liquid crystal display device according to the embodiment of the image processing system, denoted by 3 a liquid crystal display controller which detects key input data from a key input part 5 and liquid crystal addresses to be displayed on a line D and character data to be displayed to a liquid crystal display driver circuit 4 outputs. Fig. 6-1 is a detailed view of the driver circuit 4 , wherein 6 is a designated in the driver circuit 4 of FIG. 5 peripheral central processing unit for the liquid crystal display. As can be seen from Fig. 6-A, the driver circuit drives the liquid crystal display device 202 as a matrix. That is, it is actually a set of four driver stages including the peripheral Zentralein unit 6 is provided, extending in the longitudinal direction of each driver stage 40 lines, so that there are 160 vertical lines. 16 lines COM1 to COM16 of the peripheral central processing unit 6 are used for the control 8 lines. By means of the 160 × 8 lines, the driver circuit 4 drives the 32 sets (160 × 8 dots) of the 5 × 8 liquid crystal display items shown in Figs. 3 and 4 so that 3 characters are displayed in accordance with the address data from the control unit. The number of dots and display units changes depending on the language used. Denoted by 7 is a main CPU which is for various controls of the copying machine and the description thereof is omitted here. The embodiment of the image processing system according to the invention is constructed in the manner described above bene.

Below is briefly described the appearance of the display ben.

According to FIG. 3, the device on the liquid crystal display 202 data to be displayed are roughly classified into key characteristic of the function keys 201 sets (SK1 to SK6) divided messages to the operator and input data from the numeric keyboard 108. To distinguish a program key label from a message, a parenthesis is added while the underline flashes when an input from the numeric keypad 108 is requested.

To distinguish a selected from a non-selected program key label a question mark is added to a non-selected label and a selected label sets an exclamation point nachge. Therefore, a function indicating the selected function identifier is provided for each function, wherein the control unit 3, the identifier turns on when the choice of the function is completed.

Further, in the selection of the copy functions using the program buttons 201, various program button labels are displayed on the display device 202 , and typical program button labels are commonly used for individual functions as shown in Table 1 below.

Program-button label function ETC To recall dialing lists and settings that are not shown on the display. To return to the original ad. YES, NO To answer the displayed messages and to progress. OK To effect the function setting required by the keypad input. Confirm To confirm the contents of the copy type. To confirm the content to be set during the setting and saving of functions (although the modification is possible during confirmation, an addition is impossible since, other than "option", only the set function is displayed). option To perform a deletion, a change and an extension of the copy type content. Explain To determine what type of input the display is expected to be and how to enter it when the display is in an input-wait state.

With regard to the functions mentioned above the operation of the display below in detail described.

When the power supply is turned on or in a state where a respective copy state is canceled, the liquid crystal display 202 is in the reset mode, namely, in the state of normal copying with the reproduction scale 100%; the appearance of the display in this state is shown in the transition state 7-1 in Fig. 6-C. Thereafter, the display 202 enters the option display mode when copying functions such as scale change are added or changed by means of the program key portion 200 of FIG .

Next, the appearance of the display after the reset display mode will be described with reference to the state transition diagram in Fig. 6-C and the flowchart in Fig. 6-B. It should be noted that in the reset display state, key input is not accepted even if a key F1 corresponding to "Reset" (a message) is pressed. In the reset display states (5.1, 5.2) in the transition state 7-1 of FIG. 6-C results in pressing the designated with "option" Neten program key F₆ (5.3) the display of the transition state 7-2 , wherein items that in the Reset state can be added or changed as program button labels are displayed (5.4). In the transitional state 7-2 , by pressing the program key labeled "ETC", the remaining program key labels are displayed, as shown in the transition state 7-3 (5.6). Thereafter, "ETC" is entered again to return to the default mode display state at the transition state 7-1 if there is no "Option" program key label to be displayed (5.7).

Entering with the option label program button to be selected in the display state according to the transition state 7-2 allows selection of the desired option (5.8).

The process of setting individual options becomes described in more detail below.

Upon completion of setting of individual options, the display returns to the setting initial state according to the transition state 7-2 or 7-3 .

For example, when inputting with the program button "NEG", the operation unit switches the copy function "generating an image under white / black inversion". Thereafter, the display changes to the transition state 7-4 , whereby the question mark behind the program key label is changed to an exclamation mark to indicate that the "NEG" input is set. Thereafter, at the transitional state 7-4, an input is made with the "ETC" key, the indication being from the state 7-4 to the state 7-1 as in the case of returning from the state 7-3 to the state 7-1 replaced. Although the transition state 7-1 'is the same as the state 7-1 in the rank order, the state 7-1 ' indicates the reset mode as the "option" since the option function has been set. This condition is called the option mode. However, if an option function provided with an exclamation mark is to be changed, the function change is possible by entering it with a program key for its program key label, but impossible if a change is not allowed due to the content of the other set option functions. For example, in the transition state 7-2 "EDIT" is the abbreviation for the editing function selection; if the reproduction scale can be determined solely by the choice of this rendering function, the entry with the program key F4, which is a change in the reproduction scale, is not accepted and an exclamation mark of the program key label of interest is flashing for the indication that the change is impossible is shown. In the above example, the comment mark flashes at the label "→!", Which indicates the true format at the transition state 7-2 (5.1).

Returning from the option mode to the reset mode, input is made with the reset button 301 of FIG. 2. Entering with the reset button 301 clears any functions ever set and the liquid crystal display 202 gives the reset mode indication according to FIG Representation as state 7-1 in Fig. 6-C (5.1).

The appearance of the display 202 and the assumption of a program key input associated with the mode change between the reset mode and the option mode have been described. Next, the copy function setting operation using the program buttons in the transition states 7-2 and 7-3 will be described.

As copying functions which are considered to be suitably adjustable using the program keys, the setting of the reproduction scale, the selection of a sorter mode, a sortie and a used channel, the determination of the original reading position, the selection of a paper feeding tray and the Formats of the copy material, the determination of the image editing process and the setting of the transmission destination for the image (in a copier with a facsimile device). Here, the setting of the reproduction scale will be described with reference to the transient state diagrams in Figs. 6-C and 6-E and the flowcharts in Figs. 6-8 and 6-D. In the transient state 7-1 of FIG. 6-C, the label "→!" Indicating the true-format copying is used. for the purpose of facilitating the change of the scale, the operability is improved in consideration of the fact that the return mode is often used solely by changing the scale. To change the scale, the program key for the scale indicia label is pressed with the underline ( Fig. 6-B, p. 4), whereby the reproduction scale can be changed ( Figs. 6-B, 5.8).

The reproduction scale is set by two methods, namely, once by determining the reproduction ratio in% as the original ratio with the number keys, and secondly by selecting from set scale values. When the program key F4 of Fig. 6-C, 7-1 is pressed, the display changes to that shown in Fig. 6-E, 19-1, wherein the setting of the scale is initiated (6.1). In the state 19-1 have the keys F₁ to F₆ corresponding labels or terms the meaning of a Verklei nerung between fixed formats (F1), a magnification between fixed formats (F2), the determination of the copy in real format or 1: 1 (F3), the determination of any given scale (F4), the separate determination for the longitudinal direction and the lateral direction (F5), and the confirmation of the setting state before the change of the wet stick (F6).

If the function key F1 for the label of the reduction is pressed between fixed formats, the display changes to the state 19-2 , in which the programming time labels are the reduction combinations between fixed formats all or z. T. (6.2). Thereafter, as indicated at state 19-6, the input by means of the desired program key determines the reproduction scale, turning on a function setting flag (6.3) to display the page flag, and changing the display to state 7-2 of FIG. 6-C changes. If the desired combination is not displayed at state 19-2 , other remaining combinations are displayed as state 19-3 by pressing the program key labeled ETC. Thereafter, upon pressing the program button for the desired reduced ratio displayed, the display changes to state 19-6 . If there is another input "ECT", the state 19-3 is displayed if other combinations exist, while the display returns to the state 19-1 for selecting the type of reproductive scale to be set when there are no other combinations (6.5 ). That is, by continuing to press the function key ETC, it is possible to switch off the operating mode and select other modes of operation.

In the state 19-1, when the program key F2 for enlargement is pressed between fixed formats (6.6), the display proceeds in the same manner from the state 19-4 to the state 19-2 . If the program copy key F3 for the format-true copying is pressed at the state 19-1 (6.7), the display returns to the option-entry-approach state as shown in the transition state 7-2 except for the reproduction ratio 100%. This also applies to the case that the confirmation button F6 is pressed in the state 19-1 .

If the scale selection is input at the state 19-1 with the program key F4 (6.8), as shown at the state 19-7, an indication "RR SEL" indicating that the operation unit is awaiting input of the scale is made; the underlining on the S4 key flashes, which means that the entry is requested with the numeric keypad (6.8). RR is short for "reproduction ratio". Here, the scale is determined (such as 123%) by inputs with the ten-key 108 (6.9) and the enter key 109 of Fig. 2, after which the display is made in accordance with the state 19-8 in Fig. 6-E ( 6.10). If the scale has been selected incorrectly, the error message is displayed, waiting for the scale to be entered (6.11). If it is intended to change the selected value at state 19-8 , by pressing the program key (here F4) at which the selected value is displayed, state 19-7 is displayed to indicate that a new choice has been made of the value is possible (6.1). In state 19-8 , by pressing the program key labeled OK, the state changes to state 7-2 , while state 19-14 is maintained at the specified scale (6.13). It is also possible, after entering with the numeric keypad at the state 19-7, to set the selected value by the input by the enter key to switch to the state 19-14 , which is represented by the dashed lines (6.14).

If, in the state 19-1, the program key F5 for the separate selection of the scale in the vertical and Hori zontalrichtung is pressed, there is a switch to the state 19-9 (6.15). In the state 19-9 , "XY Ind. RR Sel (Numeric Keypad)" indicates the current state and the input device, and then, after a certain period of time measured by a timer, displays the wait state for the input of the scale on the display for the X direction at state 19-10 (6.16). Alternatively, the operator is allowed to set the display to the input wait state by pressing the clear key 104 of FIG. 2 or the like. In state 19-10 , the abbreviation RRX (reproduction scale in X-direction) is displayed and the value of the scale in the X direction according to RRX selected before the display in state 19-9 is added, and the underline blinks under RRX and the selected value to request the input of another value.

When the scale in the X direction is entered using the number keys in conjunction with the enter key, the display changes to the state 19-11 where the input of the Y direction scale is awaited (6.18). If an input is made solely by means of the input key , the value previously displayed at the state 19-10 is kept unchanged, thereby eliminating the need, in the case where only the scale for the Y direction is to be changed, the value for the To re-enter the X direction, which should not be changed; in this way, the operability is improved (as in the case that only the value for the X direction is changed).

The previously selected value above the underline becomes cleared by the numeric keypad and it becomes the means The numeric keypad displays the new value entered (6.19).  

The numeric keypad input will highlight the underline, which has flashed to which the change indicating pro program key label, where the underlining stops to blink.

After the scale for the Y-direction has been entered in the same way, the display has the state 19-12 (6.20), in which the selected values for the two directions are entered by means of the subdivisions below the display area for the selected scale can be changed after the RRX and RRY displays (6.21). The scale values indicated above the underlines which flash to indicate the changes in states 19-10 and 19-9 may be either those obtained prior to reaching state 19-1 or those values, which have been changed by entering with the Enter key. The same is true regarding the scale display in state 19-7 .

If an entry is made with the program key designated OK in the state 19-12 of FIG. 6-E, a display as shown in the state 19-13 is produced and switched to the state 7-2 of FIG. 6-C ,

When, as shown in Fig. 6-E, at the state 19-1, the confirmation of the state selected before the change of the scale values is requested, the values selected before the state 19-1 are displayed even if these values are input by the state 19-1, canceling the values selected at that time (6.23).

In state 19-10 , the program key label for program key F5 is "Explain". This label is displayed to counteract the difficulty encountered due to the condition 19-9 and the display of the data entered by the operator, that an inexperienced operator can not perform subsequent input operations. This device has the function of informing the operator of the present input state and the input method by switching the indication to the state 19-9 with the input of this program key label (6.17). Instead of an input device having this function, a conventional key (not shown) may be used for a fixed function.

Furthermore, in the operating unit, a preselection key be provided, which by means of a one-off Key input a sequence of the above Operations brought about in a memory get saved.

Furthermore, when operating the entire system or the setup error and enter the key Be not allowed, in addition to the above information given on the label display areas in detail the error condition and a countermeasure to correct the error.

Furthermore, to select a desired mode or a desired data value another key are used as the aforementioned program key.

Since it is possible, as stated above, on unused parts of the label display areas for the program buttons the message for the operating person and entered by the operator  Displaying data will use the label indicator areas effectively improved, the requirement deleted, additional display areas for messages or to provide notifications; that way the Operating unit simplified.

Furthermore, the key labels and the operating instructions lines at the same display areas so that the operator can do the functions without regard to other facilities can choose and thereby the operability is improved.

In addition, through the measures to distinguish the message from the program key labels a Operating error reduced by the operator be facilitated, the operation and the for the operation time required to be shortened.

Therefore, the invention provides an image processing system created with a simple operating device, in which the function can be selected reliably can, the usability is improved and the display to confirm a selected function on the program button display area.

Hereinafter, an operation unit according to egg nem further embodiment of the invention Image processing system in detail in connection described with the appearance of the display and so on.

Fig. 7-A shows the state of the display on the display device 202 in the program key part 200 , when the power is turned on or the reset button 301 is pressed in Fig. 2 for returning to the real-format copying.

A region a in which left-hand side crystal liquid crystal display units 11 are included is an area for indicating the determination of the output preparation mode, and without failure, each of the characters of Fig. 7-B is displayed. In Fig. 7-B, DPAD is the abbreviation for "Document Position Autodetection". A region b of FIG. 7-A, which includes five display units, is an "auto-matic display area, and as shown in FIG. 7-C," Auto "is displayed only when in the edit modes the automatic fixed scale A range c including ten display units is a scale display area in which any one of the displays shown in Fig. 7-D is displayed, and in Fig. 7-D, a range dd is set Example of scale values input by the operator When a key "SKC" corresponding to "ETC" shown in Fig. 7-A is pressed, the display changes to the state shown in Fig. 8-A.

An area d of Fig. 8-A, which includes five display units, is a display area for on / off switching of the negative / positive inversion in which any of the characters of Fig. 8-B is displayed. An area e containing eleven display units is a transmission mode selection area in which any one of the displays shown in Fig. 8-C is displayed.

As an example of the function setting, the operation for setting the scale change function will be described with reference to the flowchart of a scale setting shown in FIG. 9-B. By pressing the key SK4 in Fig. 7-A, the message "100% !!!" (for the real-format copying), the display device 202 will display a display as shown in Fig. 9-A. If any key except the key SK6 corresponding to "CLR" is pressed, the unit is switched to the scale change mode. Pressing the key SK6 corresponding to the clear "CLR" and "CANC", respectively, returns the display to the state before selecting the scale-change mode, namely, the state shown in FIG. 7-A. Thus, the key SK6 represents one of the reset keys. When the enlargement-copy key SK1 shown in Fig. 9-A is pressed, the magnification changes appear along with question marks according to the area bb in Fig. 7-D. Pressing SK6 for "ETC" displays the desired magnification value; if the key is pressed for a desired value, the question mark is exchanged for an exclamation mark indicating that the value is set. Likewise, by depressing the key SK2 indicative of the reduction copying, an indication of the reduction changes according to the area bc in Fig. 7-D is made along with question marks, and the key is similarly selected. Pressing the "95%" corresponding key SK3 or the "100%" corresponding key SK4 gives a selected scale value as shown in the area ba in Fig. 7-D together with the exclamation mark. Fig. 9-C shows the display state on the display 202 when the key SK5 corresponding to "% SEL" is pressed. The procedure for setting any scale change mode starts from the state 9- a, in which the reproduction ratio in the X direction is not the same as that in the Y direction, or from the state 9- b where the two Standards are the same. By depressing the key SKL for "CLR", a given scale change mode is cleared, whereafter the state returns to the state before the setting of the mode, namely the display state of Fig. 9-A (where the key SK6 represents one of the reset branches). ,

If, in the display state 9- c "NO !!!" button SK5 is pressed, the display changes to state 9- d. At the areas with flashing Unterstrei tion is set using the numeric keypad 108 and the input key 109 of FIG. 2, a desired scale such as 123%, which is switched to the display state 9- e. Pressing the SK5 key for "NO?" gives the display state 9- e. Thereafter, pressing the key SK5 for "OK" gives the state 9-g indicating the setting of the scale. If the scale is to be further changed, by pressing a setting area corresponding to the key (such as shown in Fig. 9-h, the display is returned to the state 9- d, after which the scale can be readjusted.

In the display state 9- c, pressing the SK4 key for "YES?" the display on the state 9- i of FIG. 9-D to. In state 9- f, pressing the button for "YES !!!" the display on the state 9- i of FIG. 9-D to.

The appearance of the display is described in Fig. 9-D. In the state 9- i, to set the scales in the X and Y directions, the underlines on the X-direction scale display part flash. When the scale is entered by means of the ten-key and the enter key, the display changes to the state 9- j, whereafter the underlining of the Y-scale display areas blinks to set the yardstick for the Y-direction. Similarly, when the scale (such as 78%) is entered, the display changes to state 9- k. By pressing the key SK4 the display changes state 9- c of Fig. 9-C to the condition 9-k of Fig. 9-D. Here, when the scale is changed, by pressing the corresponding key such as 9-1 or 9- m (for 2: 1), the state returns to the display state 9- n or 9- j. The state 9- k is switched to the state 9- p by the depression of the key SK5 for "OK", whereby the setting of the reproduction ratio is completed.

In the display states 9-1 , 9- j, 9- k and 9- n, pressing the function key or program key SK6 for "CLR" returns the state to the state shown in FIG. 9-A before setting the scale ( FIG. so that the key SK6 is one of the reset keys).

The transmission mode brought about by input with the key SK2 according to FIG. 8-A will now be described (see flow chart in FIG. 10-A). By entering with the key SK2 of Fig. 8-A, the display state is switched to the state 10- a of Fig. 10-b.

After the expiry of a measured by a timer period of time, the display state changes to the state 10- b. Here, the transmission destination is set ( Fig. 10-A, state 10 aa). "# 1?", "# 2?" and "# 3?" are number addresses for terminals. The message in the parentheses is the message to the operator, so that in the display state 10- b is no input with the function key SK1 when it is pressed. When a function key corresponding to a desired transmission destination terminal is pressed, the question mark changes to the exclamation point indicating that the key input is recorded. In this embodiment, three terminals are shown, but more than three terminals can be used. Now, if all the terminals (excluding the own terminal) are selected as transmission destinations with the key input operation, the display state changes to the state 10- c of Fig. 10-b. However, in the display states 10 b and 10 c returns the display state to that shown in Fig. 8-A state, pressing the clear key SK6 while pressing the SKS button for OK the display state to the state 10 d for the Transmitter cassette format selection toggles ( Figures 10-A, 10-bb).

In transmit mode, the choice of transmit cassette format, the format of the message sent to the Destination to be sent to printing sheet. If at the destination no leaves of this format present, the transmission is interrupted and a Display caused the interrupted transmission indicates. On the other hand, in the transmission mode format selection is not required with your own printer, taking the format selection automatically taking into account The format of cassettes takes place on the own Printer are attached. According to the above Ausführun conditions are different transmission states to the display areas that are distinguishable from each other are.

Next, the framing mode will be described with reference to FIG. 11-A. In frame mode, the choice is made as to whether to color or blacken an unused area of the image area (FIGS. 11- b). In this case, pressing the button for SK6 CLR returns the display to the state 11- aa of FIG. 11-B. Similarly, as shown in FIG. 7-A, when the program key SKI is pressed for "EDIT?" the display is switched to state 11aa . In the display state 11- bb of FIG. 11-B is pressed by pressing the program key SKI or SK2 the identifier for the whitewashing of the unused portion of the Bildflä surface, while pressing the program button SK3 or SK4 the identifier for the blackening of Unused area is turned on. Thereafter, at step 11-e of Fig. 11-A, the frame location is set by means of the clear key 114 and the enter key 109 . Referring to Fig. 11-B, the display state 11- cc (for a given time period measured by the timer) is switched to the state 11- dd, and the underline blinks, which is the wait of the input from the ten-key. Thereafter, the frame location is set by the ten-key, for example, as shown in the display state 11- ee. If the value is to be changed, the reset key 114 of Fig. 2 is pressed to reset (the erase key 114 is also regarded as one of the reset keys) or a program key below the value to be reset is pressed. In the display state 11- ee of FIG. 11B, by pressing the key SK5 for OK, the display is switched to the state 11- ff for the setting of a shift location (corresponding to the step 11-d of FIG. 11-A). The display state 11- ff is switched to the display state 11- gg by means of the timer. Pressing the program key SK1 results in a progression from the step 11-d in the direction "No" (in which only the scale is changed) to the step 11-h, in which the automatic full-page normalization (AFPS) the automatic solid-scale Normalization (AFRS) or scale selection (RRSel) is selected.

In the display state 11- gg of FIG. 11-B, pressing the program key SK2, SK3 or SK4 results in switching the mode to the step 11-e, 11-f and 11-g of FIG. 11-A, respectively the frame surface is moved.

If the frame area is moved to a specific location ben is the program key SK2 for "SSL?" pressed (Setting the identifier for the determination the shift destination), as in the case of the adjustment of the frame location to set the shift location and to the step 11-h for the scale adjustment stride.

After proceeding in the direction of "No" at the step 11-e and then in the direction "Yes" at the step 11-f in Fig. 11-A, namely, when in the display state 11- gg of FIG -B the program key SK4 is pressed (turning on the code for correction, the program proceeds to the step 11-h of FIG. 11-A for the scale adjustment (which is the same as the scale-change mode in which the original on the corner of the original carrier is hung up).

Next, the determination of the move destination, the shift to a corner and the shift to the middle of framing or frame mode briefly explained with reference to the figures, which are the relative positions between the template carrier and the template.

Fig. 12-A shows a state in which the original is placed on the original support and the original support surface, respectively; where the place of origin (0,0) at the upper left corner of the document carrier, wherein 903 of the document carrier shown in Fig. 1-B is designated and 12 -a is referred to the template. The frame location, as shown in FIG. 12-B, is determined by specifying values TXMAX and TXMIN for the X-axis and TYMAX and TYMIN for the X-axis (in mm) for diagonal positions ( 12- b, 12- c) at either Rectangular surface set.

In setting the target location for the displacement of the frame area, it is determined where a location ( Fig. 12-B, location 12- b) is moved between the specified minimum X and Y axes in the frame area ( Figs. Position 12- b ').

Next, the shift to the corner will be described. For forming the coordinates of the minimum position 12- b in the frame area of Fig. 12-B (0, 0), the X-axis and Y-axis values of the positions 12- b are respectively determined from the X-axis and Y-axis. Subtracting axis values at the four locations of the frame area to define the resulting locations for different coordinates as displacement locations 12- b 'and 12- c' ( Figure 12-D). If thereafter the scale is to be changed, an enlargement or reduction operation is performed. For example, FIG. 12-E shows the reduction and FIG. 12-F the enlargement, wherein in each case the position 12- b "of FIG. 12-D remains unchanged.

Next, the shift to the center will be described. Fig. 12-G illustrates the procedure for determining the shift location based on the data input by setting the frame location (the coordinates of the locations 12- b and 12- c of Fig. 12-B). Fig. 12-H is a representation of a shift to the center, wherein the format is doubled in both the X direction and the Y direction. In Fig. 12-G, the length of a copying paper in the X direction and the Y direction are denoted by the PSX and PSY. In step 12-aa, TXMAX-TXMIN and TYMAX-TYMIN give the effective frame width in the X-direction and the Y-direction, respectively, where the values are multiplied by the scale values to determine the lengths in the X-direction and the Y Direction at the frame surface which is actually copied. In this way, the values TXM and TYM are as shown in Fig. 12-H (in which the scale MX = MY = 2).

Referring to Fig. 12-H, in the X direction and the Y direction, the values are "0" or positive. Therefore, in step 12-bb, if not TXM ≧ 0 and TYM ≧ 0, there are no coordinates on the document support, so that a warning is displayed. On the other hand, at TXM ≧ 0 and TYM ≧ 0, the location 12- b in Fig. 12-B is shifted so that TXM is substituted for TYMIN, the result being that shown in Fig. 12-H.

Next, the blanking in the output preparing mode will be described. Fig. 12-A is a flow chart for this. In the display state 11- aa of FIG. 11-3, the fade-Be 'BLANK? "Gives triebsart by pressing the function key SK3 or SK4, corresponds (display state 13- a of FIG. 13-B).

If SK1 or SK2 is pressed, the blanking area or blank area is colored white, while pressing the SK3 or SK4 key will cause the blanking area to turn black; with the next key input, the display is switched to the display state 13- b (step 13-aa of Fig. 13-A). After that, pressing the key SK4 will result in "YES?" (Step 13-bb of Fig. 13-A) the display state 13- c, after which the display is sequentially switched in the order 13-c-13-d-13-e-13-c, that in the respective state, the key SK5 for "ETC" is pressed. On the other hand, in the state 13- a, when the key SK6 is pressed (for CLR), the display returns to the state 11- aa of Fig. 11-B, and a reset is possible; if the key SK6 is pressed in the state 13- b, the display returns to the display state 13- a. Similarly, the display returns to the display state 13- b at the state 13- c, 13- d or 13- e by the depression of the key SK6. In the display state 13- e, MIN is the smallest format, LTR is the letter format, LGL is the legal format, and LDR is the general ledger format. If, for example, in the display state 13- d, the program key SK4 for "B4?" is pressed (step 13-cc of Fig. 13-A) and in the step 13-dd the Ausblendestelle is set, the original in the format B4 is automatically changed and copied to the format of the selected paper cassette. If, at the step 13-bb of Fig. 13-A, the original format is indefinite, namely, in the display state 13- b, the key SK5 for "NO?" is operated, the display is switched to the display state 13- f of Fig. 13-B. Thereafter, by pressing the reset key SK6, the display is returned to the state 13- b of Fig. 13-B. Then, the coordinates are set by inputting by the ten-key, and at step 13-dd of Fig. 13-A, the blanking position is set in the same manner as the frame location. The display state 13- g of Fig. 13-B is an example of the setting. In this case, the blanking area is displayed white (white blank) with the reproduction scale automatically set (AFRS), so that even by pressing the program key SK4 for "100%", the scale adjustment is impossible.

Next is the automatic template attitude detection (DPAD).

Fig. 14-A shows a state in which the original is placed on the original support of the reader A of Figs. 1-A and 1-B. Although the support position is in principle determined by the place of origin, the template can be placed obliquely according to the representation in the figure. If the key SK5 for "ETC" is pressed in the display state 11- aa of FIG. 11-B, the display state shown in FIG. 14-E results. If then the key SK1 for "DPAD?" is pressed, the operating mode for automatic position detection is achieved. In this position detecting mode DPAD, a desired area of an original can be easily copied by placing the original in a suitable position on the original support, even if the original is not aligned with the reference level on the original support.

Referring to Fig. 14-A, by pre-scanning and detecting by means of an optical system during a pre-run of the printer four sets of coordinates (X₁, Y₁), (X₂, Y₂), (X₃, Y₃) and (X₄, Y₄ ) obtained when the main scanning direction and the sub-scanning direction from a reference coordinate origin SP on the document carrier are respectively defined with X and Y, respectively; thereby, the format and the position of a template can be determined, so that therefore the scanning distance of the Abtastvorrich device can be set in a multiple copying and a desired cartridge can be selected. A document cover 904 ( Fig. 1-B) is mirrored so that the image data reliably gives black values except for an area on which the document is placed. The whole surface of the glass sheet is scanned in advance in the main scanning direction and the sub-scanning direction, followed by scanning for printing. In the pre-scan, the sub scan speed is higher than that for printing.

Fig. 14-B is a logic circuit diagram for acquiring the aforementioned coordinates. Image data VIDEO, which is divided into two values during the pre-scan, is input to a shift register 501 in units of 8 bits. After completing the input of the 8 bits, a switch 502 checks the 8-bit data for whether or not all the white image data is; if the answer is "yes", level "1" is output on a signal line. A flip-flop 504 is set when a first 8-bit white signal occurs after the start of the original scan. The flip-flop is reset in advance by a signal VSYNC (picture leading edge signal) and remains set until the next signal VSYNC is received. When the flip-flop 504 is set, a value reached at this time by a main scan counter 551 is input to a latch flip-flop 505 . This input value is the X-axis value. Meanwhile, a value obtained at that time from a sub-scanning counter 552 is input to a buffer 506 . This input value is the Y₁-axis value. Accordingly, the Koordina th (X₁, Y₁ scored for a point P₁.

Each time a level "1" is output on a signal line 503, the value obtained from the main scanning number is input to a latch 507 and immediately stored in a buffer 508 (before the next 8 bits are input to the shift register 501 ) , Into the latch 508 is input a value obtained by the main scan when the first 8 bits for "white"occur; this value is compared by means of a comparator 509 in terms of size with the data value in a buffer 510 (which is preset to "0" upon receipt of the VSYNC signal). If the data value from the buffer 508 is larger, the data is input from the buffer 508 , namely, from the buffer 507 into the buffer 510 , while at the same time the value from the sub-sample counter is input to a buffer 511 . This process is completed before the next 8-bit signal is applied to the shift register 501 . If the data from the buffer 508 and the buffer 510 are processed in this way over the entire image area, the maximum value of the document surface remains in the buffer 510 in the X direction, while in the buffer 511 the value remains in the Y direction ( Coordinates P₂ (X₂, Y₂)).

A flip-flop 512 is set when the first 8-bit white signal appears on a respective main scanning line and is reset by a horizontal synchronizing signal HSYNC. The flip-flop is through the first one. 8-bit white signal is set and held in this state until the next signal HSYNC arrives. When the flip-flop 512 is set, the value of the main scan counter is set in a latch 513 and input to an intermediate memory 514 before the next signal HSYNC arrives. A latch 515 is preset at the generation of the signal VSYNC to the maximum value in the X direction. The data from the buffer 514 is compared to the data from the buffer 515 by means of a comparator 516 . If the data value from the buffer 515 is greater than that from the buffer 514 , a signal 517 takes effect, the data value being input from the buffer 514 , namely the buffer 513, into the buffer 515 . This operation is performed after the first signal HSYNC is generated and before the next signal HSYNC is generated. The above comparison is made over the entire image area, with the smallest value of the template coordinates in the X direction remaining in the buffer 515 (X₃). When the signal 517 is output on a signal line, the value from the sub-scan counter is input to a latch 518 (Y₃).

In latches 519 and 520 , at each occurrence of an 8-bit white signal, the values from the main scanning counter and the sub-scanning counter, respectively, are inputted, and this process is carried out over the entire image area. Therefore, in the latches at the completion of the original prescan, the count values attained when the last 8-bit white signal occurs (X₄, Y₄) remain.

The data lines from the above-described eight buffers ( 506 , 511 , 520 , 518 , 505 , 510 , 515 , 519 ) are connected to a bus BUS of the central processing unit (CPU) shown in Fig. 6-A, which terminates this data to complete the data Read out prescan. A region within the coordinate components X₂, X₃, Y₁ and Y₄ in this data is set as a template area, after which the framing is performed during the scanning of the original for printing. That is, by means of the template coordinate components X₂, X₃, Y₁ and Y₄, the coordinates of a rectangle can be recognized, which is shown by a dashed line on which the template points P₁ to P₄ are; Therefore, it can also be seen that at least sheets of the corresponding format are required.

Next, an embodiment will be described. where automatic template capture is performed and an automatic-scale standardization command is entered, reducing the reproduction scale for the content of the template is changed so that he corresponds to the format of the sheets in a cassette, and the contents printed on the sheet from the cassette becomes.

As shown in Fig. 14-C, values mx and my are determined, namely, values for the ratios of the sizes Δx and Δy of the original in the X and Y directions to the sizes Px and Py of the sheet in the X, respectively or Y direction. The smaller value of the ratios thus obtained is set in a random access memory (RAM) as a ratio common to X and Y, and the above-described reproduction scale change is carried out to automatically normalize one due to the size of the sheet in one direction to obtain the right scale copy.

Referring to Fig. 14-D, the ratio of the size of the original in the X direction and the Y direction to the size of the sheet is calculated in the X and Y directions, respectively, and it becomes the scale for the X direction and the scale for the Y direction is set separately, whereby the image of the original can be copied on the entire surface of the sheet. The above-mentioned two ways of automatic scale change are the same as in the above automatic scale normalization, which is carried out together with the frame coordinate setting.

In a similar way, the format definition means in the second type, the determination of the cassette sheet.

Next, the black frame erasing will be described. That is, for example, as shown in Fig. 12-A, the frame part of the original is copied into "white". If you press SK2 or SK3 as shown in Fig. 14-E, which "BLACK FRAME ERASE?" 12, the display changes to the state 15- a of FIG. 15-A with the black frame blanking being set. The following procedure will be described with reference to the Ablaufdia program in Fig. 15-B. If, in the 15- Anzeigezu a 15-A was shown in Fig. The program key SK4 for "YES?" is pressed, which means that the original has a normal format (step 15-aa in Fig. 15-b), the display changes to state 15- b. Thereafter, the key SK5 for "ETC" is pressed until the desired format is displayed, in which case the display is sequentially changed to 15 -b, 15- c, 15 -d and 15- b. Assuming that the desired format is the A3 format, because of the display of A3 in the state 15- b, the program key SK4 becomes "A3?" is pressed (step 15-bb in Fig. 15-B), whereby the original size data are set in a main memory as data for A3 and the display is switched to the display state 15- e for the selection of automatic solid scale normalization (step 15 -cc in Fig. 15-3). If then the key SK4 for "YES?" is pressed, is automatically determined according to the subroutine SUB AT₂ and SUB AT₁ shown in FIG. 14-C and 14-D according to the foregoing description of the scale change of the reproduction scale and the black frame hiding setting abgeschlos sen. On the other hand, if the program key SK5 is for "NO?" is pressed, the display changes to state 15- f and the real format mode is set (reproduction ratio 100%). However, this ratio can be changed by operating the ten-key (step 15-ee), namely, by pressing the program key SK4 which is "100% !!!" in the display state 15- f. speaks.

If the original is in an unusual format, in the display state 15-2 of Fig. 15-A, the program key SKS for "NO?" pressed to change the display to state 15 -g. As a result, the original size is determined by inputting the data via the number keys (step 15-ee). The following procedure is the same as that for the template in the normal format. That is, the black frame blanking mode corresponds to the frame mode for the whole original. Furthermore, at each display state, by pressing the program key SK6 for "CLR", the display is returned to the previous state.

Next, the book template mode is described ben. When the function key is pressed for SK5 "ETC" in the display state 11- aa of Fig. 11-B, the display changes to the state of Fig. 14-E. If the function key SK4 for "BOOK?" is pressed, the book template mode is set. Fig. 16-A shows the display conditions in the book style operating mode setting and Fig. 16-B is a flow chart here for.

When the key SK4 is depressed as shown in Fig. 14-E, the display changes to the state 16- b of Fig. 16-a, indicating the types of copying. That is, it becomes HALF L (left half only), HALF R (right half only), HALF LR (successive copying of left and right halves on separate sheets), and FULL (copying left and right halves onto the same sheet ) is displayed. If any of the keys are pressed for this, the display changes to state 16 c. In the main memory, an identifier for the corresponding copy mode is turned on in accordance with the depressed key, and the coordinate data is entered by means of the ten-key pad and the printing cycle is brought up to date. The display state 16- c concerns the format of the book original (normal size or not) (step 16-ff). If the key for "YES?" is pressed, the display changes to state 16- d with "A6" to "A4" displayed. Then, when the "ETC" button is pressed, the formats "137" to "135" are displayed (state 16- e), and then, when the button for "ETC" is further pressed, "MIN" and "LTR" are displayed , Assuming that the A4 format is correct, the data value for A4 is set ( 16- gg) and the display state 16- j for the suitability of the automatic solid-scale normalization is reached (step 16-hh). If a desired format is not displayed or the format is unusual, the display state is changed from state 16- c to state 16-g for requesting input of the length in the X direction (blinking pointer mark). If it is set, for example by means of the toe nertastatur the value "175" and the A playback button is pressed, the display changes to the state 16 h, in which the input of length is required in the Y-Rich processing. Then, when the value "250" is set, the display state 16- i is reached (step 16-jj). In this state, if an error is detected in the data, the length in the X direction can be corrected by operating the key SK1, and similarly, the length in the Y direction can be corrected by operating the key SK3. If length values in the X direction and the Y direction are set which are above a limit value, pressing the Enter key displays the message "MIS BOOK SIZE SET". If not, at state 16- i, the OK button is pressed to advance the display to the subsequent scale-up display 16j . If the automatic solid scale normalization (AFRS) setting button is pressed in the state 16- j, the state 16- k becomes "AFPS?" displayed (automatic full page normalization). If the key for "YES?" is pressed, in accordance with the above-described subroutine SUB AT₂, the reproduction ratio of the size of the original and the format of the copy paper determined and it is displayed the state 16-1 . If, on the other hand, the key for "NO?" is pressed, the reproduction ratio in the same manner as in the subroutine SUB AT₁ is determined, the state 16 -m is displayed. On the other hand, if the button for rejecting the automatic solid scale normalization is pressed, the state 16- n is displayed and the true format copying is set. At state 16- n, the scale may be changed in the manner previously described. The steps following the step 16-hh are the same as those in the above-described black frame suppression mode. At states 16-1 to 16- n, the copy types are also displayed, which means that the book template data setting is completed.

Fig. 16-c shows the relative position of the book template to the support surface, wherein the book along the usable edge portion of the support under orientation of the cover Rüc kens is placed with a point "BOOK". L and R are scanning lines of the optical unit for printing the left half and the right half, respectively, or the whole book surface.

Referring to Fig. 16-B, before proceeding to the automatic solid scale normalization, the coordinates corresponding to the copy mode due to the format data verscho ben (primary shift), namely in the case of L-Be mode according to TM MIN ← Y₁, TYMAX ← (Y₂ + Y₁) × 1/2, and in the case of the R mode and the mode "FULL" according to TYMIN ← (Y₂ + Y₁) × ½, TYMAX ← Y₂, wherein the shift data for L and R are stored. Thereafter, at the completion of the automatic solid scale normalization routine, the above-described center shift routine is executed, namely, the original is offset from the offset coordinates and the reproduction scale to the center to set the final coordinates. In addition, in the case of the L mode and the R mode, the reversal point of the optical unit is determined from the offset coordinates and thus set as follows: (Y₁ + Y₂) · 1/2 + r for the L mode and Y₂ + r for the R mode and the "FULL" mode. In the "HALF LR" mode, if the optical unit returns to the home position at the completion of the first left half scanning cycle, the main CPU determines whether an ID LR is turned on in the work memory when this code is turned on Central unit outputs the data for the right half. Thereafter, the optical unit starts scanning for the second cycle to print the right half of the original on the sheet. The left and right halves are printed on the center of the sheet.

The DPAD mode for the automatic document registration is almost the same as the book template mode: In the DPAD mode, the position and format of the original are automatically detected and entered into the main memory, while the book templates Mode the position of the original is specified and the format of which is entered into the main memory by operating the program keys. That is, it does not include the routines for book templates in the normal format or the unusual format as shown in Fig. 16-B, and does not display the scale values obtained when automatic scale normalization is selected.

As a result, in the DPAD mode, the coordinates are shifted when, after the copy key is pressed, the optical unit reads the coordinates of the original during the pre-scan. That is, the primary coordinate shift, the shift to the center, and the reverse attitude adjustment of Fig. 16-B are performed during the pre-scan and before the start of the normal scan.

In DPAD mode and book template mode art automatically fades the black frame fades out framing.

In the above-mentioned blanking mode, the fade-out and reversal of data read out from the charge coupling device takes place by means of the circuit shown in FIG . Signals VIDEO CCD1 system and VIDEO CCD2 system are obtained by changing the Bildqua quality of the two output signals of the charge coupling devices by fading or the like and stored for a line in the X direction in shift registers 57-1 and 57-2 . From the shift registers, an image data signal VIDEO is output in accordance with the scale change data and the displacement data.

In Fig. 18 are distinguished with 90 and 91 Antivalzglieder BE, which are controlled by a signal OF. The signal OF fades out the inner frame part determined by an ST counter 80 and an EN counter 81 , and outputs an image signal output for the part outside the frame when it has the level "1"; if the signal OF has the level "0", the signal results in an image signal output for the part within the frame and a blanking of the part outside the frame. 92 is an AND gate for controlling the output of the image data. 93 is an AND gate for determining whether the hidden part is output in "black" or "white". BB is a signal for the control of the AND gate 93 , wherein the signal at the level "1" causes the output of the blanked part in "black" and at the level "0" the output of the blinded part in "white" , 95 is an OR gate for outputting the image signal output from the AND gates 92 and 93 as the signal VIDEO, and 94 is an anti-valence gate for controlling the white / black inversion of the image data. IN is a signal for controlling the exclusive-OR gate 94 , wherein the signal at the level "1" gives the output of the image data as a natural image of the original, while at the level "0", the data is reversed. The respective signal is output when the signal unit determines that the operation of the program buttons "BLANK", "WHITE BLANK", "BLACK BLANK" or "NEG" is input.

When the ST counter counts down at the "1" fade-in signal, the output Q of a flip-flop 82 changes to "1" level and the output of the exclusive-OR gate 90 becomes "0" level, while the AND gate 92 has no output signal until the EN counter has counted up or the signal Q changes to the "0" level, namely, is switched off. Since, instead, during this time, the output of the exclusive OR gate 91 has the level "1", at the level "1" of the black / white signal BB, the AND gate 93 has the output level "1", so that the image output OR gate 95 continues to output the level "1", namely performs a black-blanking. On the other hand, when OF = 1 and BB = 0, a white-out glare occurs. Since, at OF = 0 and BB = 1, the output signals of the exclusive OR gates 90 and 91 become "1" and "0", respectively, the part outside the frame is reproduced in black. On the other hand, when OF = 0 and BB = 0, the part outside the frame is reproduced in white. The ST counter and the EN counter are preset by means of the above-mentioned blanking point setting data.

The mode setting program has been described above. Next, preselection keys used for storing the modes set in this manner will be described. There are eight kinds of storages possible, namely the reproduction scale, the output preparation mode, the positive / negative reproduction, the destination and the transmission format, the copy format, the original image quality, the number of copies and the density. If the function key SK5 for "REG" is pressed in the display state of Fig. 8-A, the display state of Fig. 17-A results, and when the key is pressed, the copy modes are stored by the preselect keys. In addition, the modes stored by means of the preselection keys can be combined with each other, or a combination of these modes can be newly stored. However, if there are operating modes that are incompatible with each other, their priority must be taken into account. The priority is determined by comparing the above-mentioned identifiers.

Fig. 17-B is a flow chart of the whole Einrich device, wherein as the display 1, the display state of Fig. 7-A is designated, as display 2, the display state of FIG. 8-A is indicated and display 3 as the display state after Fig. 17-A is designated. The output preparation mode has already been described so that its description is omitted here (step S1). When the key SK6 for "ETC" is pressed, the program proceeds to the display 2. The negative / positive inversion setting state (step S2) is followed by the transmission mode (step 3).

In addition, copying is only possible for displays 1 and 2; it is possible to return to the state in which the mode is not yet set in each state by pressing the key for "CLR". The storage takes place at a step 54, which is described by standing with reference to FIG. 17-C.

Fig. 17-C is the flowchart for storage, where PK is a preselect key. When the SK5 key for "REG" is pressed, the display state changes to the storage mode (display 3) (step 17-a), and the six display devices 303 corresponding to the preselect keys 302 of Fig. 2 flash (step 17-b). Then, if the key SK6 for "CLR" is pressed, the operation of storing is interrupted and the display is returned to the display 2 as shown in Fig. 8-A. That is, by means of a clear key (or one of the reset keys), the mode setting is returned to the one-step state. On the other hand, in the state at step 17-b, by depressing any one of the preselect keys PKi (i = 1 to 6) ( Fig. 2, 302 ) at step 17-c, any of the preselection key display devices 303 becomes PKj (j = 1 until 6); (i ≠ j) is turned off and the display device 303 of the preselect key PKi is turned on. An ID PSi STATUS in the RAM, which changes to "1" at step 17-d when the storage is set to "1", and MAIN MODE IDs in the main memory (shown by the ones shown in Figs 11 identifiers are formed) are respectively stored at the step 17-e in corresponding PSi MODE areas of the work memory. At step 17-f, "MAIN SD TBL" is stored from the working memory (transmission data) in the area PSi-SD-TBL of the work memory, while at step 17-g "MAIN-EDIT-TBL" is cleared from the work memory (comp data) is stored in the area PSi-EDIT-TBL of the working memory.

The PSi STATUS identifier in memory indicating that the modes selected from 07615 00070 552 001000280000000200012000285910750400040 0002003348398 00004 07496r in the key PKi are stored, is switched to "1".

For the presetting process, the identifier is maintained a battery, so that they too is not lost when the power is turned off becomes; the ID is not cleared to "0" except if the first registered in the memory he follows.

As shown in step 17-h, the flag COPY MODE in the main memory is set to 2 ^{i + 1} and switched to the mode of the preselect key PKi selected as the storage destination; In this case, the corresponding preselection display device is turned on, while the remaining preselection buttons display devices are turned off.

The display assumes the state shown in Fig. 8-A, after which the storing operation is completed.

Next, the operation of retrieving the stored modes by means of the preselect keys will be described with reference to Figs. 17-F and 17-G.

When the power is turned on or input is made by the reset button for the normal mode (FIGS . 2, 301 ), the selected mode is the normal mode (true format reset) stored in main and reference mode areas of the working memory. The priority of the preselection modes is compared with respect to the main modes and preselect modes. Operation memory PSi (i = 1 to 6) of Fig. 17-F are preset mode memory in the memory for the storage of the modes by means of preselection buttons PKi (i = 1 to 6).

It is now assumed that some modes are stored only in the mode memories PS1, PS2 and PS3 under the condition that the power is turned on and the normal mode is displayed, namely, in the memory PS1, the "FRAME RR 100%" mode is stored ; In this case, when the key PK1 is pressed at a step 17-aa in Fig. 17-g, the answer is "Yes", at a step 17-bb the answer "No" since PS1 is the first input is at a step 17 for the same reason, the answer "No", at a step 17-dd the answer "No", since this mode is the main mode, at a step 17-ff the answer "yes", since the main mode is the normal mode and consequently the true format copy is selected; at a step 17-hh, the retrieval of the PS1 mode "FRAME RR 100%" is allowed, so that this P1 mode is stored in the main and reference modes shown in FIG. 17-F ( FIGS. 17-G, FIG. Step 17-kk). Even if it is attempted to input PS1 again in this state, the answer is "Yes" at step 17-bb, so that the input with PK1 is not accepted. Likewise, even if a preselect key is pressed whose mode is not stored in a mode memory such as PS4, the answer is "NO" at step 17aa, so that the input is not accepted herewith.

Assuming that the scale change type "RR 200%" is stored in the mode memory PS2, the answer is "Yes" at step 17-aa when the button PK2 is pressed, at the step 17-bb the answer is "no". at step 17cc the answer is "no", at step 17dd the answer "yes", since the editing mode PS1 is stored as the main mode, at step 17-ee the answer is "no" since the mode of operation of PS2 only for the reproduction scale, and at step 18-ff, the answer is "yes" since the true format is stored even if the editing mode after PS1 is stored as the main mode; therefore, at step 17-hh, the PS-2 mode "RR 200%" is accepted and added to the main and reference modes of Fig. 17-F (step 17-ll).

Further, assuming that in the operating spec PS3 stores the scale modification type "RRC 150%" is, pressing the PK3 button at the step  17-aa the answer "yes", at step 17-bb the answer "No", at step 17-cc the answer "no", at the step 17-dd the answer "yes", since the main operation art "FRAME RR 200%", from PS1's, and she's the make-up is the response mode at step 17-ee "No", as the operating mode in PS3 only contains "RRC 150%" at step 17-ff, the answer is "no" the scale is 200%, and at step 17-gg the Answer "No", because the operating mode in PS3 is "RRC 150%" is and she is the scale change type; therefore will key input with the PK3 key is not accepted and thus into the main mode with two buttons ben PK1 and PK2 "FRAME RRC 200%" as a combination of the operating modes are stored in PS1 and PS2. If this is intended to scale to, for example 152% change, and therefore using the numeric keypad "152" is entered, the main mode is turned on Changed "FRAME RRC 152%". After that will save this value in the preselection key the reset key pressed to select the preselection mode, for example, in Memory PS4 to save.

The reference operating range is used as a control for used the purpose that, if in the comparison determines a difference with the main mode area is displayed, a corresponding preselection key blinks while when no difference is detected, a corresponding preselection key is displayed becomes. The operations such as sending copies or the like on the main mode data based executed.

In accordance with the foregoing, with the invention created an image processing system that is a very expedient and very applicable operating unit contains.  

An image processing system includes a printer and a reader that is mechanically and functionally separate are so that they are used independently can, with an image information transfer between is possible for them. The reader contains an operation which varies with the printer for execution ger functions such as an image processing function, an image transfer function, a preselection function and an image quality enhancement function in addition to the function of a conventional copying machine together acts. The control unit contains a normal use Button part, a program button part, which for the wahlwei using copy transfer functions and the function keys and these keys correspond which has interacting display devices with a driver circuit, a central unit and a control unit for the display of key labels and messages for the user are det and a function key pre-selection key part, for saving, reading and resetting the image tragungsfunktionen is used and a reset key to return to normal mode, Preselection buttons and preselection button display devices which correspond to the preselection buttons and to display the reset position are formed.
