DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below with reference to the drawings, using a variable size copying apparatus as an embodiment.

-2 Reprint of the specification (no change in content) FIG. 1A is a cross-sectional view of a copying machine having a variable magnification function to which the present invention is applied.

The surface of the drum 11 is made of a three-layer photoreceptor using a CdS photoconductor, and is rotatably supported on a shaft 12''.
Rotation in the direction of arrow 13 is started in response to the copy command.

When the drum 11 rotates to the fixed position, the original platen glass 1
The original placed on 4-L is illuminated by an illumination lamp 16 that is integrated with the first scanning mirror 15, and the reflected light is
Scanning is performed by a first scanning mirror 15 and a second scanning mirror 17. The first scanning mirror 15 and the second scanning mirror 17 are arranged at t, 4
By moving at a speed ratio of , the document is scanned while the optical path length in front of the lens 18 is always kept constant.

The reflected light image described in 1 passes through the lens 18, the third mirror 19, the fourth mirror 20, and forms an image on the drum 11 at the exposure section 21.

The drum 11 is charged (for example, +) by a negative charger 22.
After that, in the exposure section 21, the image illuminated by the illumination lamp 16 is subjected to slit exposure.

At the same time, charge removal of the opposite polarity (for example -) to the AC or - is performed using the charge eliminator 23, and then the entire surface exposure lamp 2
4, a high-contrast electrostatic latent image is formed on the drum 11-1-. The electrostatic latent image on the photosensitive drum 11 is then visualized as a toner image by the developing device 25.

Transfer paper 27-1 in cassette 26-1 or 26-2
Or 27-2 is paper feed roller 28-1 or 28
-2 into the machine, approximate timing is determined by the first register roller 29-1 or 29-2, accurate timing is determined by the second register roller 10, and then sent toward the photosensitive drum 11.

Next, while the transfer paper 27 passes between the transfer charger 9 and the drum 11, the toner image on the drum 11 is transferred onto the transfer paper.

After the transfer is completed, the transfer paper is guided to the conveyor belt 8, and then to the pair of fixing rollers 7-1, 7-2, where it is fixed by pressure and heat, and then discharged onto the tray 6.

After the transfer, the surface of the drum 11 is cleaned by a cleaning device 5 composed of an elastic blade, and the process proceeds to the next cycle.

Note that the copying apparatus shown in FIG. 1A has an original platen glass 141.
: The information on the document placed on the paper can be reduced and formed on the photosensitive drum II.In order to form such reduced information, the position of the lens 18 must be changed according to the reduction magnification. , the first scanning mirror 15 according to the reduction magnification.
This mechanism changes the speed of the lamp 16 and the second scanning mirror, but since such a mechanism is already known, detailed description thereof will be omitted here.

FIG. 1B shows a top view of the copying apparatus shown in FIG. 1A, and particularly shows the direction in which a document is placed on the document table. That is, in the copying machine shown in FIG. 1A, A3
, B4 size document is placed vertically so that the longitudinal direction of the document and the moving direction (X) of the optical system match), A4. In B5 size, the width direction of the document and the direction of movement of the optical system match (
(horizontal) arrangement.

If the original is arranged in this way, it will be A3.
The B4 size transfer paper 27-1 is placed in the cassette l-26-1 so that the feeding direction F of the transfer paper 27-1 matches the longitudinal direction of the transfer paper 27-1 as shown in FIG. vertical arrangement), A4. The B5 size transfer paper 27-2 is placed in the cassette 26-2 as shown in FIG.
The transfer paper 27-2 is arranged (measured) so that the feeding direction F of the transfer paper 7-2 and the transverse direction of the transfer paper 27-2 match.

In this way, when the document is placed both vertically and horizontally in order to partially increase the copying speed during full-size copying, the information to be copied may protrude from the transfer paper during reduced copying. . For example, convert an A3 size document into A4 size or B
If a 4-size original is reduced to B5 size, and the orientation of the transfer paper on which this reduced image information is to be transferred is horizontal, as shown in Figure 1 C (b), the size of the document will be reduced to "-". Since A4 size information is transferred vertically, part of the image information remains untransferred.

Therefore, in the embodiment of the present invention, such B5.
For A4 size transfer paper, prepare a cassette with the transfer paper placed vertically in the same way as shown in Figure 1 C (A).
When instructing to reduce a 3-size original to A4 size, or when instructing to reduce a B4-size original to B5 size, configure it to use a cassette with transfer paper placed vertically. , a reduction copying function is added without reducing the copying speed of the frequently used same-size copying.

In other words, in the copying apparatus to which the present invention is applied, transfer paper of the same size is conveyed through the transfer paper transport path in the copying apparatus in directions approximately 90 degrees different during full-size copying and reduced copying. It is something that

2A and 2B show in more detail the operation panel 30 of the copying machine shown in FIG. 1B, where 31 indicates a dial for setting the number of copies, and 32 indicates the dial 31. Copy button 3 for commanding the set number of copies
Reference numeral 3 indicates a copy button that commands copying of one sheet regardless of the number of copies set on the dial 31, reference numeral 34 indicates a stop button that commands to stop copying, and reference numeral 35 indicates a copy button formed on transfer paper. A density adjustment dial 36 is used to adjust the image density, and 36 is a button that commands the feeding of transfer paper from the cassette 26-1 installed in the upper stage in FIG. 1A. This button commands the feeding of transfer paper from the cassette (cassette) 2B-2 installed in the lower row of the screen, and the size of the transfer paper stored in the cassette selected by button 36 or 37 is displayed on display 3.
This is what is displayed in 8.

A part of the operation panel is formed with four parts 41, and buttons 40-1 to 40-5 for instructing the size to be reduced are housed in the four parts 41.
The upper part is a lid 3 which is slidably provided so as to cover the four parts.
9 is provided and constitutes a reduction operation section.

This M39 can be closed as shown in FIG. 2A so that the buttons 40-1 to 40-5 cannot be operated, or M39 can be closed as shown in FIG. 2B. The buttons 40-1 to 40-5 can also be exposed for operation by moving the cover to an open state.

The lid 39 is made of transparent or translucent glass or plastic, and the button 4 can be pressed even when the lid is closed.
The structure is such that the presence of numbers 0-1 to 40 to 5 can be confirmed from the outside through the lid.

FIG. 3 shows this reduction operation section in more detail, and a part of the bottom plate 42 constituting the bottom of the four parts 41 has the buttons 40-5 to 40-1 (but buttons 40-3 to 40-1).
1 (not shown), rails 43-1 and 43-2 are arranged on both sides of the bottom plate 42, and the bottom plate 42 and the rails 43-1 and 43-2 constitute the four parts. It is. As mentioned above, 39 is a lid made of transparent or translucent plastic or glass.
Since angles 44-1 and 44-2 for holding the rail 43 are fixed to both sides of the lid 39, the lid 39 can be slid along the rail 43 in the direction indicated by the arrow S.
It can move in any direction. Kagaru Angle 44-1
．． A claw 45-1.45-2 is fixedly provided on a part of 44-2, and a spring 46 is suspended between the claw 45-1.45-2 and a substrate (not shown). , the lid 39 is always biased (=f) in the closing direction (downward direction of the arrow).

A part of the rail 44-2 is further provided with a claw 47, and by moving the lid 39 in the opposite direction of arrow T to open the lid, the claw 47 holds the lid 39 rotatably. The arm 48 that is
0 and rotate counterclockwise.

Since the lever 51 is provided integrally with the arm 48, the arm 51 rotates counterclockwise to bias the actuating pestle 53 of the microswitch 52 in the direction of arrow U, thereby driving the switch 52. The signal is derived by

In other words, in the open state as shown in FIG. 2B, the operating punch 53 of the switch 52 is pushed downward by the lever 51, and the contact point a (not shown) and the contact piece C are in contact with each other. condition other than Figure 2B (for example, Figure 2
In the state shown in FIG. A), the operating punch 53 is not pushed downward, so that the contact point C (not shown) does not come into contact with it.

Note that 54 is a damper, and 55 is a projection fixed to the rail 44-2. When the lid 39 is pulled and closed by the spring 46, the projection 55 and the damper 54 are connected to each other. The arrangement is such that after contact, the lid is gradually closed by the operation of the damper 54.

As mentioned above, the lid 39 is always biased in the closing direction by the spring 46, but the open state of the lid 39 is maintained by a click mechanism as shown in FIG. 3B. .

That is, a circular through hole 57 is formed in a part of the angle 44-1.
and a pole 59 biased in the direction of arrow W by a spring 58 is disposed in a part of the rail 43-2, and a part of the pole 59 enters the through hole 57 when the lid 39 is open. , against the tensile force of the spring 46, FIG.
It is constructed so that the lid can be kept in the open state as shown in FIG.

] - As a mechanism for holding the lid in the open state as described above, the fourth
It is also possible to use an electromagnet as shown in Figure A.

That is, a tongue piece 60 made of metal such as iron is attached to the end of the lid 39.
An electromagnet 6 has a coil 63 wound around a core 62 at the location where the tongue piece 60 is located when the lid is open.
1 is arranged. This coil 63 is the fourth
As shown in FIG. The lid can be placed in a closed state. If a switch is used instead of the power switch 65 that turns off when copying is completed, the lid can be closed when a predetermined number of copies have been completed.

It should be noted that the parts not shown in FIG. 4A have the same structure as in FIG. 3A, and the members labeled with the same numbers are made of the same members.

As mentioned above, since the reduction operation section can notify the lid closed state and the opened lid state by the output of the switch 52,
By opening the lid, a reduction instruction signal can be derived.

FIG. 5 shows another embodiment of the reduction operation section, which covers the fourth section 70 housing the button 4o.
A lid 66 is provided, and an arm 67 is provided integrally with the lid 66.
68 is rotatably held by a shaft 69, and when the lid 66 is opened, the contact between the lid and the microswitch 71 is released, and a contact point a (not shown) housed in the microswitch comes into contact with the contact piece C. do.

When the lid 66 is closed, the operating punch of the microswitch 71 is pushed and the contact between the contact point a and the contact piece C is broken.
The contact piece C comes into contact with a contact point (not shown).

As described above, the reduction signal can be derived by opening the lid using the switch 71 of the reduction operation section shown in FIG.

”: If configured as shown below, switching between full-size copy and reduced copy can be instructed by opening and closing the cover of the reduction operation section, so when copying at full-size 4, reduction is possible without requiring any operation. The operation button is hidden by the lid to prevent erroneous operation, and copies can be made in exactly the same way as a conventional full-size copying device, and when making a reduced copy, the buttons necessary to select the reduced size are pressed. The action of opening the cover simultaneously switches between equal size and size reduction, making the mechanism easy for the user to understand and operate.

In addition, the selection of the temporary reduction rate for reduction copying has conventionally been often expressed in terms of the area ratio of the copy to the original, but for the user, only the size of the original and the size of the copy are of interest; Rates are generally difficult to understand. Therefore, in the embodiment of the present invention, combinations of originals and copies that can be reduced are listed, and the user presses the size button (switch 40) of the required combination.
-1 to 4O-5). When any one button is pressed, an indicator lamp lights up within the button to clearly indicate the pressed position. Also, pressing this reduction size selection button is a necessary condition for determining the position of the lens that determines the reduction ratio, so if none of the reduction size selection buttons are pressed, it is necessary to avoid making erroneous copies. The machine does not operate, and the lamps (all size buttons) that originally indicate that the reduced size selection button is pressed flash to warn the user that the button that instructs the reduced size is not pressed. It looks like this.

By pressing the reduction size selection button and specifying the copy size, the installed paper supply cassette must match the specified size. Furthermore, as described above, the relationship between the direction of the copy document on the document table and the direction of copy paper feeding is considerably more complicated than in a device dedicated to the same magnification.

Therefore, in the embodiment of the present invention, user confusion is prevented in the following manner. First, place the original in exactly the same way as when it is at full size. This allows two types of cassettes of the same size, vertical and horizontal, but the machine determines which cassette to use and displays a warning to the user about the correct cassette. That is, of the two installed upper and lower cassettes, the cassette size selected by the upper and lower selection buttons will be lit up, and if that size is not the correct cassette to make the specified copy, further conversion will be performed. The correct cassette size to be used is indicated by another flashing lamp, and at the same time a warning message "Please change to the flashing cassette" is displayed.During this time, the machine will not operate even if you press the copy button.Switching the upper/lower selection button or When the correct cassette is installed by replacing the cassette, the blinking lamp and warning display will disappear and copying will begin.

In this embodiment, a blinking lamp is used as a warning display, but it is also effective to use sound or change the color of a lamp to call attention to other things.

Further, when the other reduced size and the transfer paper size stored in the cassette do not match, a reduced size button corresponding to the selected transfer paper size may be displayed.

As mentioned above, in the fifth embodiment of the present invention, correct copies can be obtained by following the machine's instructions without requiring the user's judgment, and the conventional complicated and difficult-to-understand operation mechanism is replaced with an easy-to-understand operation mechanism. It also has an easy mechanism.

Next, a detailed explanation will be given based on a specific example circuit.

FIG. 6 is a circuit diagram of the present invention. First, I will explain the symbols in the diagram. SW1 in the figure is the selection switch 52 for selecting the same size or reduction, which is operated by the above-described opening/closing button of the same size or m small size. SW2 to SW6 are reduced size selection buttons 4 in Fig. 2B.

SW7 is a switch operated by the cassette selection buttons 36 and 37 shown in FIG. 2. When button 36 is pressed, contacts 1 and 3 are connected, and when button 37 is pressed, contacts 3 and 2 are connected. SW8 and SW9 are switches operated by a cam plate of a cassette (not shown) to detect the presence or absence of a cassette, and are turned ON when a cassette is present. 5WIO to 5W16 are switches operated by the cam plate of the cassette, and are switches for detecting the size of the cassette. Table 1 shows the ON-OFF states of the switches when various cassettes are installed.

Table 1 8 PLI and PL2 are lamps that display the same size reduction, respectively, PL3 to PLIO are lamps that display the size of the cassette, PL3 is a cassette that feeds A3 size transfer paper vertically, and PL4 is A4 size. , PL5 uses a B4 size vertical cassette, PL6 uses a B5 size horizontal cassette, PL7 uses a large universal cassette, PL8 uses a small universal cassette, PL

Further, the lamp PLII is used to instruct replacement of the cassette, and the lamp PL12 is a lamp used to notify the inspection of the cassette. Here, the terminals T3 to TIO are terminals for deriving transfer paper signals indicating the transfer paper size and the direction of the transfer paper to each part of the copying device, and in a state where such transfer paper signals are being derived, the copy button 32 or By pressing 33, the copying apparatus is controlled with a sea fence corresponding to the transfer paper.

Next, the operation of the circuit shown in FIG. 6 will be explained. First, the case of same-size copy will be explained. When the reduction operation section MB2 is closed, the contacts 1 and 3 of the switch SW1 are electrically connected, so the lamp PLI lights up to indicate that it is a full-size copy. Also, since switches 2 and 3 of switches SWl are open, each manual power II of inverters ICl to IC6 is
I II are all at the logical "t" level (hereinafter referred to as "
(denoted as H°゛), each output 2 of inverters ICI to IC6
are all at the logic II O11 level (hereinafter referred to as "L"). In this way, the data inputs D1 to D of the latch IC12
4. Data input Di and D2 of latch ICl3 are all “L”
o, the outputs Q1 to Q4 of the latch IC12 and the output QIQ2 of the latch ICl3 are all "1L", and the outputs Q1 to Q4 of the latch IC12 and the output QI of the latch ICl3,
Q2 is all H.

NAND gate ICl3 has input 1.2 as latch IC12
Output Q3. Since it is connected to Q4, output 3 is 'L'
, L, therefore, the input l of AND gate IC23 is L゛°
Therefore, the output 3 of the AND game) IC23 becomes L°.

Next, since the input of the AND gate IC24 is connected to the output Q2 of the latch IC12, it is "L", so the A
The output 3 of the ND gate IC24 is also "L". Since the input 1 of the ND gate IC25 is connected to the output Q2 of the latch ICl3, the input 1 is "L", 1. Therefore, output 3 is also L. Also, the input 1 of the AND gate Ic26 is connected to the output Ql of the latch ICl3, so the input is 'L'.
``Therefore, output 3 is L'''.

Also, the inputs 1 to 4 of the NOR gate IC27 are AND gates)
Since it is connected to the outputs of C23 to C26, all inputs are “
"Lo", and the output 5 is "H11". Then NAN
D game) Input 1 of IC22 is output Q of latch IC12
Since it is connected to 1, it is “L” and therefore the output cuff is “
l HII, then input 2 of NAND gates IC29-IC33 are outputs Q2-Q4 of latch IC12, latch IC
Since the output Ql of l3 is connected to Q2, it is “'L”l.
Therefore, all outputs 3 are "H".

2 Now, in this state, as shown in Figure 1, an A3 size cassette is installed on the upper cassette stand, a B4 size cassette is installed on the lower cassette stand, and the upper/lower cassette switch SW7 is set to the -E side. The switch SW7 is electrically connected between 1 and 3. ” An A3 size cassette is set in the second row, so from Table 1, switch 5WIO to 5W.
12 is conductive. Therefore, AND game) IC8~
ICII's human power is all 'L' AND gate IC8
~Each output 3 of ICII is all “L”, so it is a latch IC
14 inputs D1 to D3 all become “L” and output Ql-Q
3 are also all “L”. Therefore, decoder ■C16
The inputs A, B, C, and D of the decoder IC 16 are all ``L'', the output O is ``L'', and the other outputs 1 to 7 are all ``H''. Therefore, the NAND gate connected to the output 0 of the decoder IC 16 ) Input 2 of IC36 becomes L11, output 3 drives the base of transistor Tr4, and
drives the lamp PL3 and the cassette size is 3. The inputs 1 and 2 of IC21 are the outputs 6 and 7 of the decoder IC16.
Since both are connected to ``H'', the output 3 is ``L11''.

Therefore, the inputs of the NAND game) IC28 and IC34 connected to the output 3 of the NAND game) IC21 are also low.
', and its output becomes H''. From the above, NAN
Since the inputs of the D gates IC37 to IC44 are all "H11," the outputs of the NAND gates tC37 to IC44 are all "L11," and the transistors Tr5 to Tr12 are
are all OFF, and lamps PL4 to PL11 do not light up. Also, since the output 3 of the AND gate ICII is connected to the input l of the NAND gate IC45 via the inverter IC46,
Input 2 of the cassette is a signal from another circuit (not shown) that indicates the presence or absence of paper in the cassette.

Therefore, if this signal is HII indicating that there is paper in the cassette, the output of the NAND gate IC45 is "
When the signal becomes ``L'', the transistor Tr13 is also turned off and the lamp PL12 does not light up. Conversely, if this signal is ``L'', the lamp PL12 lights up to prompt inspection of the cassette.

Next, when the cassette selection button 37 is pressed and the B4 size cassette is selected by setting it in the lower row, the switch SW is pressed.
7's 2-3 are connected, and Table 1 as in the case of A3 above.
Therefore, the input of the decoder IC16 is A is L”° and B is PH′
”, C becomes “L” and D becomes “L”, so decoder IC1
The output 2 of 6 is L°, all others are H, and the lamp PL5 lights up in the same manner as above, indicating that the cassette size is B4.

Thereafter, by similarly inserting another type of cassette into the cassette insertion slot and selecting it with the button 36 or 37, the selected cassette is displayed.

Therefore, in such a state, the copy button 32 or 33
By pressing , transfer paper is fed out from the designated cassette, and copying is performed using a sea fence corresponding to the fed-out transfer paper.

Now here, use the cassette for reduced copying) A4 (R) (but R
indicates vertical feed) is set in the cassette insertion slot, and this cassette is selected by button 36 or 37. In the same way as above, Table 1 shows that the input to the decoder IC 16 is A is L' and B is 'H'. ”, C is “H”, D is “L”
``', and the output of the decoder IC 16 is 6 is L''.

, and everything else becomes “H Pa”.

Therefore, the lamp PL9 lights up and the output 6 of the decoder IC16 is low, so the NAND game) IC2
The input 1 of the NAND gate IC21 also becomes "L", and the output of the NAND gate IC21 becomes "H", and the input 2 of the NAND gate IC28 becomes "H".
is also “H”. Also, the input l of the NAND gate IC28
is connected to the collector of the transistor Tri, which is connected to the Schmitt trigger IC7 and the resistor R6.
, and capacitor C1 constitute an oscillation circuit 6, and the output of transistor Tri is 0N-
Since the OFF is repeated continuously at a certain period, the NA
The input 1 of the ND gate IC28 changes alternately between "H" and "L", and the output 4 of the NAND gate IC28 also changes to H''
Repeat “L”. As a result, NAND gate IC3
Similarly, input 1 of 6 to IC41 is °l Hll II L
As II is repeated, the lamps PL3 to PL-8 blink. Furthermore, the output of IC21 (NAND game) is II H1
1, the input l of the NAND gate IC34 becomes "H", the output of the NAND gate IC34 becomes "L", the input l of the NAND gate IC44 also becomes "L", the transistor Tr12 turns ON, and the lamp PLII lights up. In this way, A4 cassette A4 with vertical feeding for full size copying
The lamp PL9 lights up to indicate that A4(R) is currently selected, and the lamp PL9 indicates the first-class borrowed cassette.
3-PL8 is dimmed and the lamp PLII, which instructs the replacement of the seven cassettes, lights up, giving a warning to the operator and instructions for the next operation. Similarly, when vertical feed cassette B5 (R) of B5 is set and selected, the lamp PLIO lights up, the lamps PL3 to PL'8 decrease, and the lamp PLII lights up, giving a warning and the next operation. give instructions to the operator.

Next, the case of reduced copy will be explained.

When the operator of the copying machine wants to make a reduced copy, he first opens the lid shown in FIG. When the connection is made, the lamp PL2 lights up to indicate the reduction copy mode.

In this state, it is assumed that the button 40-2 is pressed to select a reduction from A3 to A4, and the A3 size cassette is selected using the button 36 or 37. In such a state, the switch 5W3-1 becomes conductive, current flows through the light emitting diode LD2, the light emitting diode LD2 emits light, and it is displayed that reduction from A3 size to A4 size has been instructed.

Also, at the same time, between switch 2 and 3 of switch SWI and switch 5W
3-1 becomes conductive, the input 1 of the inverters ICI and IC3 becomes L'', and the output 2 of each becomes H'°.At this time, the inverters IC2, IC4, IC5, IC6 (7)
Input is switch 5W2-1.5W4-1.5W5-1
.

Since 5W6-1 is open, the signal is "H". Therefore, the inputs DI of latch IC12, D2°D3. D4 is “H”
””L” “H”゛L°', latch ICl3 input DI
, D2 becomes L""'L", and the output (Qt, Qt) of the latch IC12.

(C2, C2), (C3, 03), (C4°C4) are (
H""L")("L""H")("H""
L")("L"H''), and the outputs (Ql, Qt), (C2, C2) of latch ICl3 are (""L""H").
” ), (“L” “H°゛)”. Also, since an A3 size cassette is selected, the output of the decoder Ic16 is 0 at L°', and the other outputs 1 to 7 are at H''.

As mentioned above, inputs 1 and 2 of NAND gate ICl3 are NA
Since it is connected to C3 and C4 of the ND gate IC12 and both outputs are "H", the output 3 of the NAND gate ICl3 is "L", so the AND gate 1-IC23
Since the input 1 of the AND gate IC23 is also "L", the output 3 of the AND gate IC23 is "L".The input 2 of the AND gate IC24 is "L".
is connected to the output 2 of the decoder IC16 via the inverter ICl3, but the output 2 of the decoder IC16 is “H”.
”, the input 2 of the AND gate IC24 is L''
The output 3 becomes "L". AND gate I
Since the input l of C25 is connected to the output Q2 of the latch ICl3, it is at L''°, and the output of this AND gate IC25 is also at L'°.The input l of the AND gate IC26 is connected to the output Q1 of the latch ICl3. Therefore, the output of the AND gate IC 25 is also "L".

Therefore, the inputs 1 to 4 of the NOR gate IC27, which has the outputs of IC23 to IC26 as inputs, are all "C".
L” 5.: (7) NOR gate Ic27
The output 5 of the NAND gate IC22 becomes "H". Since the input 3 of the NAND gate IC22 is connected to the output Q3 of the latch IC12, it becomes "L".
The output voltage of the NAND gate IC22 is 1H". The input 1 of the NAND gate IC35 is the output voltage of the NAND gate IC22, and the input 2 of the NAND gate IC22
The input 3 is connected to the output 5 of the latch C12 and the input 3 is connected to the output Q1 of the latch C12, and all of them are "H", so the NAND gate IC
The output 4 of 35 becomes L''.

, Z's NAND game hIc35(7) output 4 is NAND
Game) Since it is connected to input 2 of IC44, it is NAND
The output of the gate IC44 waves a current to the base of the transistor Tr12, the transistor Tr12 turns ON, and the lamp PLII lights up. Input 1 of NAND gate IC21
, 2 is connected to output 6.7 of decoder IC16, NAND game) IC21 (7) output 3 is "L"
Therefore, input 2 of IC28 (NAND game) is also “L”
”, and the output 4 of the NAND gate IC28 becomes “H”. Also, the input 2 of the NAND gate IC30 becomes the latch I
Since it is connected to the output Q3 of C12, it is “H”, and input 1 is “°H” and “L”.

Since the output 3 is connected to the collector of the transistor Tri which alternately outputs "H" and "L", its output 3 alternately and repeatedly outputs "H" and "L".

Also, input 2 of NAND gate IC42 is connected to output 3 of NAND gate IC31, and input 3 is connected to output 6 of decoder IC16, so input 3 of NAND gate IC42 is connected to output 3 of NAND gate IC31.
, 2 are both H+1, and input 1 is a NAND gate IC.
Since it is connected to the output 3 of the transistor Trio, "H" and "L" 11 are alternately repeated, and the output 4 of the NAND gate IC42 intermittently flows current to the base of the transistor Trio, causing the lamp PL9 to blink.As described above, Since the A3 cassette is selected, the output 0 of the decoder IC16 is L.
”, the input 2 of the NAND gate IC36 is also “L”, the output 3 of the NAND gate IC36 causes current to flow to the base of the transistor Tr4, and the transistor Tr4
NL, lamp PL3 lights up.

As a result of the above, the lamp PL3 that displays 3 for reduced copying from A3 to A4 lights up to indicate that the A3 size cassette is currently selected, and the lamp PL9 that displays the cassette A4 (R) to be selected. flashes on and off, and furthermore, the lamp PLII, which prompts the user to change the cassette, lights up, informing the operator of the change to an A4 (R) size cassette. Next, when the cassette is changed to A4 (R) size, the output 6 of the decoder ICI 6 becomes L'' and all other outputs become "H", so the lamp PL9 lights up and the lamp PL3.

PLII does not light up.

Similarly, when other size reductions are selected,
If a compatible cassette is selected, only that cassette size is displayed.4 However, if an unbeatable cassette is selected, the selected cassette size is displayed and the compatible cassette size is also displayed. is displayed in reduced dots, and a lamp is lit to prompt the operator to replace the cassette. Next, the same size reduction switching cover (lid 39) is opened and the reduction selection button (4
0-1 to 40-5) are not pressed. Since none of the reduction selection buttons are pressed now, switch 5W2-1.5W3-1゜5W4-1.5W5-
1.5W6-1 are all open, switch 5W2-2
．． 5W3-2.

5W4-2.5W5-2 and 5W6-2 are closed (however, the switches with the subscript 1 and the switches with the subscript 2 are linked with ON and OFF states being reversed). Also, since the equal-magnification reduction switch cover is now open, there is continuity between switches 2 and 3 of switch SWl, so inverter I
Input 1 of C1 becomes “L”, and output Q of latch IC12
1 is "L°', so its base is latch I.
The transistor Tr2 connected to the output Q1 of C12 through the resistor R14 is turned off, and the base of the transistor Tr3 is connected to the resistor R8 connected to the collector of the transistor Tri through the resistor R15.
The current flows alternately, and the transistor Tr3 becomes 0N-O.
I'm playing FF over and over again. Therefore, the light emitting diode LD
Resistors R1-R5 and diodes D6-D are connected to I-LD5.
10, SW 2-2, SW 3
-2.5W4-2.5W5-2.5W6-2, since current flows alternately through the collector of transistor Tr3, the light emitting diodes LDl to LD5 decrease points, and the operator does not press the reduction size selection button. Let me know.

Also, when the same size reduction switching cover (lid 39) is closed,
Since the output Q1 of the latch IC12 is "H", the transistor Tr2 is ON, and the transistor Tr3 is OFF.
Since it is FF, the light emitting diodes LD1 to LD5 are off even if the reduction size selection button is not pressed.

In the above text, latch IC12 to IC14 are
It is explained that all data inputs appear as they are in the outputs, but while the copying device is copying, even if the data inputs change, the outputs Q and Q do not change and are latched as they are. There is. This is not directly related to the purpose of the present invention, so it will not be explained in detail, but since the positions of optical lenses, optical mirrors, etc. and the exposure area of the original are controlled by the reduced size and cassette size signals, changing it during copying will cause problems. This is to prevent this.
