Abstract

PURPOSE:To extremely easily select many information by reading out numerical information in the descending order of numerals even when the numerical information is stored in a storage means independently of the size of the numerals. CONSTITUTION:A magnification value selected by an optical magnification selecting key 71 is registered by ten keys 51-60, displayed on a display part and stored in a prescribed area (address) of a previously specified magnification memory. When the numeral is stored in the memory, the newly stored magnification is compared with an already stored magnification value. At the time of transferring respective magnification values in the magnification memory to comparing and rearranging forward memories M1-M3 is order, a value specifying the memory is defined as the value of each counter to replace the stored count value. Thus, the value is selected by rotation based on an ascending order in accordance with the input of the key 71 to set up the copying magnification. Thereby, it is unnecessary to arranging many keys every optional stored magnification on an input panel.

This is a communication line for connecting with U.

FIG. 5 is a flowchart showing an outline of the processing in the first CPLI 201. As shown in the figure, the first CPU2
01 sets the initial state by turning on the power (for example, sets the various registers to the initial state, sets the set copy magnification to equal size, and sets the number of copies to "1") (step S1, hereinafter simply referred to as Sl). omitted). Next, an internal timer that defines the time for one routine is started (S2), and a magnification setting routine (S3) that sequentially sets a fixed magnification and an arbitrary magnification.

After that, when the internal timer ends, the process returns to 82 (S7).
, run a repeating routine. In addition, the above S3, S4.
S5 will be detailed later.

6, 7, and 8 are flowcharts showing details of the magnification setting routine.

In S8, when the arbitrary magnification input key 70 is input, the flag A indicating the arbitrary magnification setting mode is determined in S9, and if the flag A is ``O'', the flag A is set to ``1''.
(S10), sets the arbitrary magnification setting mode, erases the magnification display (31011, sets the 1000th digit flag indicating that input of 1000th digit is accepted or attached to 1'' (811
).

On the other hand, if flag A is 1'', flag A is turned on and the arbitrary magnification setting mode is canceled (812).Then, if the input of the 1000.100.1011 digit is accepted, set the flag to O''. 513), and the magnification selected before the arbitrary magnification setting mode is set is displayed on the display section (S14). Similarly, when the key 128 (Fig. 1) is input (S15), the flag B indicating the fixed magnification setting mode is determined (816), and if the flag B is 0'', the flag indicating the fixed magnification setting mode is determined. Let B be Pa1” and (
S18), erases the magnification display (818') and sets the 1000th digit flag to 1" (819). If flag B is 1", by setting flag B to i 0 n (S17),
Cancel fixed magnification setting mode and set 1000, 100110
．． When inputting the first digit, the flag is set to 0'' (813), and the magnification selected before the fixed magnification setting mode is set is displayed (814).Also, when the clear key 62 is input (820) ), flag A1 flag B is determined (S21.522), and if it is arbitrary or fixed magnification setting mode, only the 1000th digit flag is set to 10 as °゛1''.
It is possible to input the 00th digit (823).

In 824.825, flags A and B are determined and if it is the magnification setting mode, the state is that of a manual numeric keypad.

When the numeric keypad is input in this state, the type of the key is determined at 828, and only when the "1" key is selected, the process proceeds to step S29 and ll 11) is displayed at the 1000th position on the display section 102.

Note that here, i is used for convenience due to the relationship with the magnification display section 102.
The number of digits of the input numerical value is expressed in the format of ooo, 100, 10, and 1, but the numerical value as a magnification is treated as a decimal number with 3 digits after the decimal point and 4 significant digits.

If the 1000th digit flag is "1" and the input value is 0 or 2 to 9, the process advances to step S31 and i
Display “0” in the ooo digit (first digit of 4 digits). Next, if "0" is entered using the numeric keypad, "1" is entered.
”, the process advances to step S30 and the value 1000 is input.
Set the digit flag to ○''', set the 100th digit flag to Pa1'', and wait for the 100th digit to be manually powered by the numeric keypad. If the input is 2 to 9, the 1000th digit flag is set to “○’° in step S33.
After that, the process proceeds to step 836, where the input numerical value is displayed on the display section 1020100 digit.

Note that when the 1000th digit flag is "1", the processing described above is based on the premise that values in the range of 0.647 to 1°414 are treated as valid copy magnifications; Only "1" or "0" can be displayed in the digits. Also, by doing this, i ooo
The key operation for inputting "0" into the digit digit is simplified. Note that even if such processing is executed, there may be a case where the numerical value inputted below the 100th digit falls outside the range of the above-mentioned effective copy magnification. The processing at this time will be explained in subroutine 1.2 shown in FIGS. 9 and 10.

In S30, when a numerical value is input in the 1000th digit,
The 100th digit flag becomes "1", and when the numeric keypad is entered in this state, the numerical value corresponding to the 100th digit is input (
S34.335), similarly to 829, the numerical value is displayed in 836, and the 100th digit flag is set in S37.
0'' and the 10th place flag to 1'' is executed. Thereafter, the input of the 10th place and the 1st place are also performed in the same way using the numeric keys (838-545).

FIG. 8 shows that the numerical values inputted and displayed through the process of FIG. 7 are recorded in a predetermined area (predetermined address) of a designated memory. 12 is a flowchart showing a process for (store). Further, FIG. 9 is a flowchart showing the process of FIG. 8 848.

In S46, first, it is determined whether the mode is the arbitrary magnification setting mode or the fixed magnification setting mode by determining whether the flag A is "1". If the flag A is "1", the mode is the arbitrary magnification setting mode. Since there is, the process proceeds to S47 and subsequent steps where it is determined whether the arbitrary magnification select key 1 has been input, and when the flag A is not '1'', the process proceeds to 858 and subsequent steps where it is determined whether the fixed magnification select key 69 has been input. In the process shown in FIG. 8, in any magnification setting mode, the numerical value displayed on the display section 102 is stored in a predetermined area (address) of the memory designated in advance. However, as described above, at this stage, a numerical value that is outside the range of permissible copying magnifications may be displayed. Therefore, in the process of FIG. 8, after determining the input of keys 71 and 69,
The subroutine 1 shown in is executed to prevent numerical values outside the permissible range from being stored in the memory.

In FIG. 9, if the display on the display section 102 is not "0000", in step 868, it is determined whether the numerical value displayed on the display section 102 is smaller than 0.647;
If it is smaller, the display is set to 0.647 in S69. Also,
In S70, the numerical value displayed on the display section 102 is 1.
It is determined whether or not it is larger than 414, and if it is larger, the display is set to 1.414 in S71.

Therefore, in relation to the flowchart shown in FIG. 8, when the magnification select key is input in any magnification setting mode, if the displayed value is outside the allowable range, the display is allowed. After setting the limit value,
The displayed numerical value is stored in a specified area (designated address) of the specified memory. That is, in the case of an arbitrary magnification, "magnification memory Q1jr magnification memory Q2" and "magnification memory Q3" specified by the value of counter A (1 to 4)
” [Magnification memory Q4J is stored in a different predetermined area ($49 to $55), and in the case of a fixed magnification, “Magnification memory Q5” specified by the value of counter B (1 to 4) The memories indicated by memory Q6, magnification memory Q7, and magnification memory Q8J are each stored in different predetermined areas (S59 to 565).

When the process of storing numerical values in memory is executed, in the case of arbitrary magnification setting mode, subroutine 2 in 856 compares the newly stored magnification with the already stored magnification and reads them in descending order. is executed with
Flag A is returned to O'' (557), and in the case of fixed magnification setting mode, flag B is returned to 0'' (866).

FIG. 10 shows details of the processing of subroutine 2 in S56. When a new magnification is stored in the processing at 849-855 in FIG. 9, processing is performed to clarify the magnitude relationship between the new magnification and the already stored magnification (S200-3207). That is, the magnification memory Ql-
Class memories M1 to M for comparing and sorting each magnification of 04
4, the values (1 to 4) specifying the memories Q+ to Q4 are respectively set as the values of the counter DI-04. Through the above processing, the class memory M1 and the counter D1, the class memory M2 and the counter D2, the % order memory M3 and the counter D3, and the class memory M4 and the counter D4 are associated with each other, and the value of the counter D+"Da (1 to 4
) and memories 01 to Q4 are associated with each other.

Next, the magnification stored in class memory M+ and class memory M2
(S208), and if the magnification of the class memory M2 is smaller than the magnification of the class memory M+, data is exchanged (8209), and the data is exchanged (8209).
, D2. Below, kind memory M
The stored magnifications are compared between z and M3 and the class memories M3 and M4, and the magnitude relationship of the magnifications stored in the class memories M1 to M4 is compared, and the magnifications stored in the class memories M1 to M4 are compared.
The magnification stored in and the count values stored in counters D1 to D4 are replaced. In this way, the smallest magnification is stored in the class memory M1, the largest magnification is stored in M4, and the values of counters D1 to D4 are such that Da becomes the value indicating the memory in which the smallest magnification is stored, and D2 becomes the next smallest magnification. is the value that indicates the stored memory, and Da is the value that indicates the memory that is stored with the next smallest scaling factor after D2.This process continues until 4 becomes the value that indicates the memory that is stored with the largest scaling factor. Repeat. In the magnification selection routine to be described later, the magnification is selected from the magnification memories Q1 to Q4 based on the values of the counters D1 to D4 (8241 to 8241).
258).

11 and 12 show details of the processing of the magnification selection routine. When the arbitrary magnification select key 71 is input (S
217), sets the value of counter B indicating the designated order of fixed magnification memories 05 to Q8 to "0" 8218), and increments the value of counter C indicating the designated order of arbitrary magnification memories 01 to Q4 (8219). Next, it is determined whether the value of counter C exceeds "4" (8220), and if the value of counter C exceeds "4", the value of counter C is returned to "1"(8221); Further, when the fixed magnification select key 69 is input (8222), the arbitrary magnification memory Q
8223), and increments counter B, which indicates the order of fixed magnification memory specification (8224).Next, check whether the value of counter B exceeds "4". Please judge whether or not 3225
), if the value of counter B exceeds "4", return the value of counter B to "1". On the other hand, the value of counter C is determined in 5227, and if it is "0", fixed magnification memory is specified, so turn off the arbitrary magnification display LED groups 85 to 88 (8228), and if counter C is not rOJ, Since the arbitrary magnification memory is specified, the fixed magnification display LED groups 81 to 84 are turned off (8240>).

$229 to $5239 perform processing for lighting the LED and displaying the data stored in the fixed magnification memory on the display unit 102 in accordance with the value of the counter B (1 to 4). That is, if the value of counter B is 1 (S229)
, turn on LED 81 (5230), "Magnification memory Q5"
Display the data stored in J (8231>.Hereafter, turn on any of LEDs 82 to 84 in sequence according to the value of counter B, and specify any of the magnification memories 06 to Q8 in sequence. Display the magnification data.

8241 to 5247 perform a process of transferring the values of counters D1 to D4 to counter A in response to @(1 to 4) of counter C. In other words, the first shift at counter C is
1”, transfer the value of counter D blind 8241
．． 242) When r2J, transfer the value of counter Dt 8243.8244), when "3", transfer the value of counter 03 (8245.3246), when "4", transfer the value of counter D4. Transfer (8245.5
246). Therefore, the value of counter A becomes a value that specifies memories 01 to Q4 in descending order of magnification.

Next, in steps 5248 to 5258, the LED corresponding to the value of the counter A is turned on, and any one of the magnification memories from 01 to Q4 is displayed on the display section 102.

That is, when the values of counters D+ to D4 are "1", the LED 85 is lit and the magnification memory QI is specified, when the value is "2", the LED 86 is lit and the magnification memory Q2 is specified, and when the value is "3", the LED 86 is lit and the magnification memory Q2 is specified. When the value is "4", the LED 87 is turned on and the magnification memory Q3 is specified, and when the value is "4", the LED 88 is turned on and the magnification memory Q4 is displayed.

In the embodiment described above, arbitrary magnifications selectively set in advance are selected in ascending order of rotation according to the input of the arbitrary magnification select key 71, and are used as the set copying magnification of the copying machine in the arbitrary magnification setting mode. Therefore, it is not necessary to arrange a large number of keys on the input panel for each arbitrary magnification to be stored. Furthermore, even when the copying machine operator selects arbitrary copying magnifications that have been selectively set in advance one after another with a single key switch, he can easily guess the magnification that will be called up next, and the It is convenient to select the magnification.

(Reference to Other Embodiments) In the above embodiment, when reading magnifications from the memory, the magnifications are read out sequentially starting from the smallest magnification. but,
The copying machine may be provided with a separate switch for reading the magnification order, and the magnifications are read in the order of magnitude only when the switch is input, and when the switch is not input, the magnifications are read in the order stored in the storage means.

In particular, in the above embodiment, the fixed magnification display (81-84)
and arbitrary magnification display (85 to 88) are treated as separate information, but this is "magnification data"
In this sense, both data are treated as the same type of information, and 8
The magnification values of each type may be read out in a predetermined order.

Furthermore, when reading out the magnification from the memory, a switch may be separately provided to specify whether to read out in order of large to small or in order of small to large, and the order of large to small can be selected using the switch. .

For example, if the same magnification is read out in order of large to small, and then read out in order of small to large, depending on the magnitude of the numerical value, for example, lenses, mirrors, etc. that are displaced in accordance with the set magnification. There is also the side effect that positioning can be performed in a shorter time.

[Effects of the Invention] As described above, according to the present invention, even if numerical information is stored in the storage means regardless of the magnitude of the numerical value, the information is read out in the order of magnitude of the numerical value. For example, a large number of pieces of information can be selected very easily with one key switch. Therefore, according to the present invention, it is possible to provide a copying machine in which the input panel is not complicated by key switches and the like, and the input is simple.
