The present invention relates to a method and an apparatus for automatically adding machine clocks a clock sequence with different evaluation.

Especially in the field of copying technology, it is common today to determine the price of a copy as a function of the number to stagger the copies. The first and easiest option

409820/0413

is to provide a price scale in which the copy with a number of copies up to 5000 copies per month for example 0.15 DM, with a number of copies up to 15,000 copies per month, for example 0.12 DM etc.

Another staggering system wants to achieve a higher copy volume in that it is in the case of a multiple copy, for example the first and second copies at a normal price, the third to sixth copies at about half the price and the seventh and all subsequent copies are charged at a quarter of the normal price. For this economic purpose To achieve this, it was suggested, for example, in DAS 1 276 053, to use two counters, one of which only has a first fixed number and the second counter counts a number of copies that are also determined following this. In this way you can look at, for example three counters read the following values:

1) The total number of copies,

2) the number of copies, for example in the case of multiple copies as the first to fifth copies were made and

3) the number of copies made, for example, sixth to fifteenth copies. The fees could be calculated from these three meter readings for the customer at differentiated prices.

409820/0413

This counting method, however, has the disadvantage that a relatively complicated arithmetic operation is still required is, namely the copy numbers read off must start with the ' the respective price is multiplied and the numbers obtained are added together. This procedure delays the billing and harbors the risk of mistakes in itself.

Another shortcoming of this described counting system is that it is not very variable. Especially moving For example, from two to three, four or five price groups is complex and requires the installation of additional meters in advance.

The object of the present invention is to create a method and a device for counting machine cycles with different evaluations, in which the above-mentioned disadvantages are avoided. In particular, the device should be secure in terms of puncture and simple in construction, and it should be possible in a simple manner to switch to several and different calculation options. ..__ -----

This object is achieved according to the invention by a method of the type described at the outset, which is characterized in that that each cycle of the machine cycle into a counting cycle is converted, in which the number of counting cycles per machine cycle of the evaluation of the individual machine cycle correspond, and that the counts are added.

This method has the significant advantage that not how so far three, four or even more individual numbers are obtained, but that only a single number is determined in which the different evaluation of the individual machine cycle of the machine cycle sequence has already been taken into account. the Differentiated evaluation takes place before the counting, so that the incoming counting cycles simply have to be added up need and thus the use of a single counter is sufficient.

The conversion of each cycle of the machine cycle sequence into a count cycle sequence corresponding to the evaluation can be done mechanically take place. According to the invention, however, an electrical circuit is preferred because such a circuit is simpler and less susceptible to interference and is easier to replace.

In the preferred method, according to the invention, the clock sequence of the machine clocks is therefore converted into an electrical pulse sequence Pulses of identical shape are converted, the pulses of the pulse train are sent to the input of an electronic Given switching unit, which breaks down the pulses into a number of counting pulses corresponding to the evaluation, and the counting pulses are counted by a counter at the output of the electronic switching unit. It is preferred that the

A09820 / 0A13

The number that can be read off the counter gives the amount to be paid for using the machine. Then there is none Conversion more, required and the only source of error is a wrong reading of the single meter.

The different evaluation by the switching unit can be done in a simple manner that the switching unit however, the incoming identical impulses initially according to the evaluation in impulses of the same duration the evaluation of the corresponding amount and that these impulses then in a de.r voltage proportional number of Counting pulses of the same amount are converted.

The invention also relates to a device for carrying out the method according to the invention. Such a one Device is characterized according to the invention by one of the Machine cycle controlled pulse generator, the output of which is connected to an electronic switching unit that controls the Impulses are broken down into a number of counting impulses corresponding to the evaluation, and a counter with the output the electronic switching unit is connected and the counting pulses are added and one of this total number corresponding Value.

In the following, the invention will be described with reference to a device provided for a copier. In Fig. 1, a counter is shown schematically with which the method according to the invention can be carried out. Copies of an original are made in a copier machine, generally designated 1.

Explanation.

To evaluate the use of the copying machine 1 is according to the invention a special facility is provided. The machine clock generator 3 generates electrical pulses 5 of identical shape, which, after normalization in FIG. 4, reach the input 6 of an electronic switching unit 7. This electronic switching unit converts the normalized machine cycle pulses 50 as a function of the evaluation - as in the following will be explained in more detail - in counting pulses 8, which are sent at the output 9 of the switching unit 7 from a price counter 10 can be counted, added and displayed. Each machine cycle pulse 5 corresponds to a number of counting pulses 8, with the number of counting pulses depends on how many machine cycle pulse 5 of the machine cycle pulse sequence it is about.

The actual value counter 4 supplies a pulse 50 for each copy to the switching unit J. The counting pulse 50 reaches a counting switch 12 via a rectifier 11 Counter switch 12, the second pulse 50 is passed to the second output 122 of the counter switch 12 and so on. The fiftieth impulse

409820/0413

? 2 "B0632

50 goes to the fiftieth output 1250 of the counter switch The fifty-first and all subsequent pulses also arrive at the fiftieth output 1250 of the counter switch 12. From the fiftieth copy onwards, the price cannot be scaled any further.

The first counting pulse 50, which reaches the first output 121 of the switch 12, flips the flip-flop circuit 131 and brings the supply voltage to the output and thus via a diode 151 to the shift resistor 14l. The output voltage of the flip-flop circuit 131 is divided via the slide resistor I4l and the resistor 140 and, depending on the setting of the slide resistor l4l, a voltage corresponding to the evaluation of the first and second copies ^reaches the input of a frequency-controlled multivibrator 17 Indicator lamp l6l shows the price level 1.

The generator 17 delivers counting pulses 8 at the output 9, whose frequency is assigned to the input voltage. Of the Pulse 50 is transmitted to a control input 171 of the Generator 17 supplied so that the generator 17 emits the counting pulses only during the duration of the machine pulse 50. on this way the machine pulse 50 is grouped

409820/0413

converted by counting pulses 8, their number of setting of the sliding resistor 141 corresponds. This setting in turn corresponds to the evaluation ^ that for the first two Machine pulses 50 is the same. The counting pulses 8 are counted and displayed in a price counter 10.

The second machine pulse 50 arrives at the second output

122 of the counter 12. This output is free _s so that the generator 17 is also enabled by the second counting pulse reaching the control input 171 via the diode 18 and, as with the first counting pulse, a voltage corresponding to the setting of the shift resistor l4l is converted into a counting pulse group » The generator 17 thus supplies a counting pulse group with the same number of counting pulses 8 for the first pulse 50 and for the second pulse.

The third counting pulse 50 reaches the output 123 of the Counter 12. Assume in this example that the third through fifth copies cost a lower price supposed to be the first and second copy. The third exit

123 is therefore connected to the input of a further flip-flop circuit 132. The third pulse 50 causes _s that this flip-flop circuit 132 from tipping over, and thereby the supply voltage via a diode 152 to a

409820/0413

2250Θ32

Sliding resistor 1.42 and a display lamp 162 for displaying the second price level. At the same time, however, the output of the flip-flop circuit 1.32 is connected to the second input of the first flip-flop circuit 13I and the third pulse 50 causes the first flip-flop circuit I3I to flip back into its starting position. Diodes 20, 201, 202, _s 203, 204 prevent resetting of the counter and the other flip-flops.

The voltage resulting from the setting of the slide resistor 142 is now at the input of the frequency-controllable multivibrator 17. The setting of this second resistor 142 and thus the input voltage of the generator 17 differ from that of the slide resistor 141 according to the different evaluation of copies 1 and 2 compared to copies 3 to 5. The resistance * kt. is set in such a way that a lower voltage is present than the input of the generator 17. The frequency of the counting pulses 8 at the output of the multivibrator 17 is correspondingly lower. The duration of the release of the multivibrator due to the pulse 50 reaching the generator 17 via the diode 18 has, however, remained the same, since the pulses 50 themselves are unchanged. The third pulse 50 generates a correspondingly smaller number of counting pulses 8 at the output of the generator 17.

409820/0413

The fourth pulse 50 arrives at the fourth output of the Counter 12, the fifth to the fifth. These outputs are j free so that the process described above repeated and with each pulse 50 one of the setting of the Resistance 142 corresponding counting pulse sequence 8 reaches the price counter 10. '-

The sixth pulse 50 arrives at the sixth output 126 of the meter 12. From the sixth copy, the cheapest tariff should apply. Therefore, the sixth output is 126 the input of a third flip-flop 133 is connected. This flip-flop tips over, resets the second flip-flop 132

and connects the supply voltage via a diode 153 to a slide resistor 143. At the same time, a small indicator light is turned on 163 switched on to display price level 3. The sliding resistor 143 is set to such a value that at the input of the generator 17 there is an even lower voltage than that of the pulses 3 to 5. This is the sixth pulse by the generator 17 in a Sequence of counting pulses 8 converted, the number of counting pulses in this case even lower than for each previous machine pulse.

The seventh to fiftieth machine pulse reaches the seventh to fiftieth output of counter 12. In the

409820/0413

In the example provided, further price differentiation is no longer provided after the sixth copy, so that all these outputs seven to fifty are open and these copies are affected by the setting of the slide resistor 143 conditional number of counting pulses at output 9 of the generator 17 results.

The counter 12 is now designed so that it starts from the fifty-first Machine pulse 5 is switched off. The counter 12 thus does not limit the number of pulses 5 in one capturing pulse sequence, but it only limits the area within which a differentiated evaluation of the pulses 5 is possible. A fourth flip-flop, not shown, can therefore be switched at the fiftieth output of switch 12 which causes the fiftieth and all subsequent copies of one to continue to change, for example subject to even cheaper valuation.

The electrical structure of a counter 12, a flip-flop circuit 131 »132, 133 and a frequency controllable multi * vibrator are generally known. For a more accurate representation the electrical circuit of these individual elements can therefore be dispensed with.

£ 09820/0413

When the start switch 19 is pressed, the flip-flops 131 to 133 are simultaneously activated via the diodes 20, 201 and 202

The counter 12 is reset via the diode 203 and the counter 204 via the diode 204. It will be the last The sliding resistor 143 is free until the sixth copy has been produced in the copier 1 and that Flip-flop 133 tips over again.

Another example of a possible circuit for carrying out the method according to the invention is shown in FIG. From the actual counter 4 get machine pulses 50 as in the example described above in connection with FIG. 1 to a counter 12, which the various outputs 121, 122 etc.

switches through. The outputs are via diodes 3I, 32 350

held together in groups, each group being a different one Rating is assigned. The mode of operation of this switching arrangement is as follows:

The first and second counting pulses 50 cause switching through of the first and second output 121 and 122 of the counter 12. The supply voltage of the counter 12 is thus successively applied to the outputs 121, 122. These two outputs are via diodes 31,. 32 summarized and with the first Resistor l4l connected. The supply voltage of the meter 12 thus drops across the voltage divider of the slide resistor l4l and the fixed resistor 140. While

409820/0413

the duration of the first and the second pulse is thus a voltage corresponding to the setting of the sliding resistor l4l at the input of the generator 17. The third, fourth and fifth machine pulse 50 successively switches the third, fourth and fifth output of the counter 12, which are also combined, to the supply voltage. This time this voltage drops across the voltage divider of the resistors 142, 140. This means that a different voltage, determined by the size of the resistor 142, is present at the generator IJ. The normalized pulse 50 is thus converted into a different number of counting pulses 8 depending on whether it is the first and second or the third to fifth pulse 50 of a clock sequence. Finally, the sixth to fiftieth pulse is converted into a number of counting pulses.8 resulting from the size of the resistance. In this example, too, the generator 17 is only enabled for the duration of the pulse 50, in that the pulse is fed to the control input of the generator 17 via a diode. Instead of this separate control of the generator, it is in principle also possible to conduct the pulses 50 themselves via the voltage dividers 14l, 142, 143, l40. This can be done, for example, with the aid of AND elements with 2 inputs, one input of which is connected to the counter M and the second of which is connected to a group of outputs of the counter 12 combined via diodes. The Aus

409820/0413

The course of the single AND member would in this case be "with the respective resistor 14l, 142, 143 are connected. Through this the pulses 50 are controlled by the counter 12 via various Resistances led. The generator 17 must be applied or switched in such a way that it does not have any output signals when the voltage is 0 8 supplies.

With the device according to the invention, it is advantageously possible to make yet another differentiation to undertake. In copiers it is often provided that Adjust the size of the copy to the original size. There are then according to the area code or an automatic Scanning the original produces copies of different sizes. Here too, a price differentiation To enable despite the use of only a single counter, the invention provides for the number the counting cycles generated per machine cycle not only according to the different evaluation of the number of copies, but to let it be superimposed on the copy size. This measure can be done in different ways. One possibility is to switch the frequency-controllable multivibrator or multivibrators to a different characteristic. In this way it can be achieved that with an input signal of 3 volts, for example, not 200 counting pulses 8 as before, but rather 220 counting pulses 8.

9820/04 13

be procreated. This change takes place, for example, if instead of a DIN A4 copy a copy is made in the Pormal ES4 is produced.

Another possibility of adapting to the copy size consists in leaving the generator 17 unchanged and instead changing the resistor 140 in accordance with the different copy size. This changes the level of the input voltage and thus the number of counting pulses 8 per incoming machine pulse 5. This possibility of changing the resistor I ¹ JO is indicated in FIG. 2 by the fact that the resistor 140 is designed as a sliding resistor.

Finally, it is also possible to differentiate according to the copy size in that the pulses 50 each according to whether they are large or small copies, are made longer or shorter in time. The frequency duration the impulse 50 is of course given by the machine cycle. Only the duration of a pulse 50 can be changed from ten milliseconds to 8 or 12 milliseconds, for example. This will increase the duration the release of the generator 17 and thus the number of counting pulses 8 changed per machine pulse 50. The longest pulse duration must of course be smaller than the time interval between two Be machine cycles.

409820/0413

It's still with the one in Pig. I illustrated example possible and preferred as a simplification to omit the actual counter and its puncture directly via a diode connection with the outputs of the counter 12. This would save a digital counting unit. The two control functions the outputs of the counter 12 do not interfere with one another. Instead of the counter 4, there would then only be a simple standardization circuit which converts the machine clock pulse 5 into a pulse 50 standardized in terms of its length.

Another embodiment of the counting device according to the invention is shown in FIG. In this case, the differentiation of the pulses 50 does not take place through different voltages at the input of the pulse generator 17 ' but rather through different pulse lengths for the same voltage. Here, too, it is necessary that the duration of the longest pulse is shorter than the distance between two pulses 5 «

As explained in connection with FIG. 2, the first two pulses 50 reach the via diodes 31, 32 connected outputs 121, 122 of the counter 12. These two outputs are at the input of a monostable Multivibrators l8l. This multivibrator 181 converts the

409820/0413

Pulse 50 into a pulse 501, the duration of which is the Rating of the first and second copy is assigned.

The third pulse 50 of the series reaches the input of a second monostable via the third output 123 Multivibrators 182. This converts the pulse 50 into a Pulse 502 µm, the duration of which is constant but differs from that of pulse 501 according to the evaluation. With the usual staggering, the pulse 502 is therefore shorter by the percentage that the 3x to 5x copy is cheaper than should be the 1st and 2nd.

Since the outputs 123-125 are connected via diodes, the H. and 5 · pulse 50 are also converted into pulses 502 of the same length.

The 6th and all subsequent pulses arrive in a corresponding manner via the outputs of the counter 12 and diodes to the input of a third monostable multivibrator 183, which these pulses 50 when intended to repeat Reduction is converted into correspondingly even shorter pulses 503.

409820/0413

The outputs of the multivibrators 181, 182, 183 are over Diodes 301, 302, 3O3 with the input of the pulse generator 17 connected. This converts the pulses 501, 502, 503 into one that is proportional to the duration of these pulses Number of counting pulses 8 um., Which are added in counter 10.

The output of each of the monostable multivibrators I8I resp.

182 or 183 is a bistable with the first input Flip-flops 191 or 192 or 193 connected. The first pulse of the respective multivibrator causes the flip-flop to fall over, so that its supply voltage is at its output and the corresponding lamp 161 or l62 or I63 to Brings light up.

The output of the second or third multivibrator 182 or

183 is with the second input of the first or second Flip-flops 191 and 192 connected. At the first pulse 502 becomes the flip-flop I9I and with the first pulse 503 the flip-flop 192 is tilted back to its original position. This means that the lights always show the currently valid one Price level. The reset inputs of all three flip-flops 191, 192, 193 are connected to the via diodes 202, 201, 20

Reset switch 19 connected. This ensures that with each new series the advertisement with the evaluation matches.

409820/0413

to

In the example shown in FIG. 3, the The length of the generated pulses 501, 502, 503 can be adjusted. This results in an even greater flexibility of the counting circuit.

Another exemplary embodiment is shown in FIG. 4.

The differentiation is not done here by analog elements that control the frequency or cycle time of the generator 17, but by monitoring a further counter 300 which, when a predetermined number of counting pulses is reached, 8, and thus the predetermined price, no further pulses 8 during the pulse duration of the individual clock 50 the price counter 10 can get. This design has the advantage that analog elements such as resistance dividers or RC elements be avoided as far as possible, which would otherwise increase the manufacturing accuracy or in such circuits Adjustment accuracy must be sufficient.

When the first price level is reached, the output signal of the flip-flop 131 is sent to the AND gate 305. So long no further signal via the preselected output 304 of the counter 300 occurs, the OR-NOT gate 309 not controlled via any of its inputs, its output is "L" and thus the AND gate 310 switches the pulses

409820/0 413

of the generator 17, which via a diode 311 the price counter 10 and via a further pipe 321 control the tracking counter 300.

After the number of pulses preset by selecting the entry 3OM has been reached , for example 50 charge units of the pulses 8, the counter 300 sends a signal to the corresponding output 304. The AND element 305 controls the OR-NOT element 309. As a result, the AND element 310 is opened and further counting pulses 8 are omitted. .

At the beginning of the next copy, the rising edge of the next pulse 50 causes the monoflop 308 (monostable flip-flop) due to its short output pulse resets the counter 300. The process as described above is now repeated.

At the third clock 50 - as explained in connection with FIG. 1 - the flip-flop 132 is switched and the flip-flop 131 reset. The pulses 80 supplied by the generator 17 pass through the AND element, 310 as long as the OR-NOT element 309 at the output L has the counter IQ and the control tracking counter 30Q. After one of the second The number of pulses 80 required by selecting output 303, corresponding to the price level, is passed through the output 303 also to the other input of the AND gate 306 Information L.

The resulting state L at the output of the AND element 306 becomes the output of the OR-NOT element

AQ982Q / 0413

309 set by L to 0. This becomes the AND gate

310 locked; further pulses 80 do not reach the Counters 10 and 300, there is therefore a number of pulses 80 on counter 10, which corresponds to the position of the output of the counter 300 corresponds; if only 30 fee units are charged for the second price level instead of 50 are to be, the thirtieth output of the counter 300 as output 303 with the AND gate 306 of the second Price level connected. The counter 300 is reset as described by the rising edge of the next Pulse 50.

The same process is repeated at the third price level by activating the AND element 307 through the output 302 of the counter 300 to achieve a further discounted copy price.

The particular advantage of this exemplary embodiment according to FIG. H consists in the digital differentiation of the price levels by the counter 300. This makes the frequency of the generator 17 uncritical as long as at least as many pulses during the duration of the machine cycle. as they are required for the most expensive price level. The pulse shape of the pulses 50 is also uncritical in the corresponding sense. If a freely oscillating generator 17 is used, it is possible to omit di.e D, ipde 18. Then the length of the pulse is 50 fully

A0982Q / CU13

not critical, it can then also be shorter than the duration of the longest pulse packet 8 (most expensive copy).

The general technical teaching of this example according to FIG. K can be described as follows: A continuous sequence of counting pulses (80) is generated. These counting pulses are sent both to the adder (10), on which, for example, the amount to be paid is displayed, and to a control tracking counter, which starts counting the counting pulses (80) with each new machine cycle. Depending on how many such counting pulses (80) are to be processed as counting pulses (8), the delivery of the counting pulses (80) is stopped. The point in time after how many such pulses (80) the stop is to occur is determined by the selection of the output of the control tracking counter, but which output is used is determined by the counting switch (12), so that the counting switch is usually used with increasing output numbers (1, 3 '. _s 7. output), the outputs of the control idler counter in falling number (50, 30,

10. Output) can be used or controlled to abort the pulse train.
