Abstract

PURPOSE:To prevent annoying noise to the utmost, by controlling a sound volume of voice in accordance with the processes of image formation in warning with a voice on detecting trouble during copying. CONSTITUTION:A trouble detection signal is fed through an input port IA to a microcomputer CPU800, which produces a voice signal corresponding to a trouble occurring position through a voice synthesizing circuit 801 and outputs from a speaker 230 as a warning signal. At that time, it controls the sound volume of the voice in accordance with the processes of image formation. For example, when noise occurs from a motor for rotating a photosensitive drum, the sound volume is enlarged to prevent the warning from being overwhelmed, and warning is announced with low volume in the other case, thus permitting annoying noise to be prevented to the utmost.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image forming apparatus such as a copying machine, and more particularly to a device that detects an abnormality such as a sheet jam in the image forming apparatus and warns the user of the abnormality.

Conventionally, the presence or absence of a copy sheet provided in a copying machine, a jam of a sheet, etc. are detected, and a warning is given to the user by lighting or blinking a light emitting diode or the like. However, for example, if there are a large number of multi-copies, it may not be possible to immediately determine and deal with an abnormality, which may increase the risk of an accident.

Therefore, it is possible to display troubles with sounds in a round shape that makes it easy to distinguish between various abnormal conditions.

However, although the audible warning system has the advantage of making the warning more noticeable, it can also be a source of noise in a quiet office.Also, it can waste electricity if a copying machine forgets to turn off the power after copying is complete, or If an abnormal situation such as a copy paper jam occurs and the photoconductor is left unattended for a long period of time, the photoreceptor may deteriorate, or unfavorable aspects may arise in terms of maintenance, safety, etc. of the Fi copying apparatus. - As a countermeasure, if a timer was used to turn off the power after a certain period of time, the power would turn off automatically regardless of whether it was needed, making it more frustrating to have to turn it on again. .

The present invention provides an audio display that takes into account the conflict between trouble notification and noise.

That is, the present invention detects machine conditions, sea jams, or troubles in process means, and provides an audio system to detect them.
) as well as the tone quality of the warning means (tone q
quality) or sound volume
The copying process is sequential, non-sequential, and controlled. Furthermore, control is performed in accordance with a grain forming process cycle, a pre-processing cycle such as pre-cleaning of the photosensitive drum, a post-processing cycle such as post-cleaning, etc. in the copying process sequence.

Therefore, at least during the flaw forming process cycle (when there is noise caused by the main drive motor that rotates the photosensitive drum, etc.), the warning can be issued at a low volume, and therefore the noise caused by the audio warning can be suppressed. Moreover, during the process, a high-volume warning is issued! Therefore, warnings such as jams will not be drowned out by the main motor seat belt control.

In addition, the present invention detects abnormalities such as machine conditions, sheet jams, process troubles, etc. at multiple locations and issues audible warnings, as well as interrupts copying in different modes depending on the location. It controls the copying sequence and the audio means to issue different audio warnings accordingly. Furthermore, it controls different sequence interruption operations and the volume or quality of the audio warning depending on the location of the sheet jam or the object of the process trouble. If there is a problem that does not require interrupting the sequence, or depending on the degree of the problem, a voice warning will not be issued. :D, for display only on liquid crystal, etc.

As a result, the volume of the audio warning can be reduced except for jam problems that require emergency treatment, and it is possible to prevent the sound from becoming noisy.

The present invention detects machine conditions, sheet jams, or process troubles, issues audible warnings, displays them on LEDs, liquid crystals, etc., and provides either an audible warning, a visual warning, or both. It has a manual key for selection. - Selection and control of these warning means is performed according to the copying sequence or the location and degree of the jam or trouble.

This allows the volume to be lowered depending on the atmosphere of the office and the degree of urgency, thereby preventing it from becoming noisy.

The present invention also detects machine conditions, sheet jams, or process troubles, issues an audible warning, and repeats the audible warning, and also latches the repetition. The latch is released when the case is touched or the case door is opened or closed for removal or repair, and the release (reset) is activated manually to enable copying to resume after normal jam sheet removal. The button is used to release the audio warning latch.

Also, the latch of the audio warning is normally released by using the rounded clear key that cancels the number of repeat copies set in the memory using the numeric keypad. Also, the interrupt key and stop key, which normally interrupt the repeat copy sequence and hold the remaining number of copies at that time, are used to release the latch of the audio warning.

As a result, the warning can be made more conspicuous, and the sound can be easily canceled without any special means.

In addition, the present invention detects the condition of the machine, a sheet jam, or a trouble, and not only warns the user with a voice, but also repeats the voice statement, and when the number of repetitions of the statement is counted a predetermined number of times, an automatic alarm is generated. This will automatically stop the audible warning. Or, it will stop after a predetermined period of time. After the statement is stopped, the display on the KLED, LCD, etc. is automatically switched.Furthermore, when the above-mentioned clear key, etc. is turned on when the statement is repeated, the voice will stop after a predetermined number of repetitions and after a predetermined time has elapsed. Stop.

The present invention also prevents machine conditions and sheet jams.

This system detects a trouble and warns it by voice, and also allows the voice to arbitrarily or automatically select the repetition interval, number of repetitions, or repetition time of the statement. In other words, it is equipped with an input key that allows you to select the repetition interval, number of repetitions, and time depending on the copying sequence or non-sequence, or depending on the location or object of the jam or trouble. The number of copies can be set using the ten keys on the operation panel.

Further, the present invention provides a guide key and a check key at 0%, which can teach procedures for dealing with jams, etc., and copy operations using an oral atanent, and can perform one operation in 1sK.

In addition, the present invention eliminates the drawback of preventing forgetting to turn off the power, and includes means for detecting external light or external sound, a power switch,
The apparatus is characterized by comprising a warning means, and a control means for operating the warning means within K seconds by comparing the detection signal with the input state of the power switch.

Further, the above-mentioned warning is given by detecting the state of the housing switch, door switch, etc. to make the warning possible.

It also outputs a warning according to the audio statement [<s
<This is a book that outputs the same statement over and over again, and stops its continuation or forcibly cuts off the power after outputting it for a predetermined time or a predetermined number of times.In order to stop its continuation, it judges the state of the machine by checking the opening/closing of the door switch. This is performed for the first time in a predetermined state.

In the case of a copying machine, if it is detected that the intensity of external light or sound around the machine is below a certain standard level, and the copying operation is not in progress, it can be audibly detected by the operator or other people around the company. Generates sound. At this time, the above-mentioned sound is generated after a predetermined time delay after the completion of copying, after completion of exposure, or after the rotation of the transfer drum has stopped.

FIG. 1 is a sectional view of a copying machine to which the present invention is applicable.

A document is placed on a document table KW constituting a document placement surface, and is pressed down by a document pressure plate 10. The optical system is composed of an illumination lamp 9, movable reflection mirrors 8 and 6, a lens 17, and fixed reflection mirrors 18 and 19. 9g via optical system
It is bent onto the IFi photosensitive drum 30.

First, after turning on the power to the copying machine using a power switch (not shown), prepare for copying, such as the drum rotation time until the cleaning of the photosensitive drum 30 is completed, or the waiting time until a certain standard temperature rise of the heat fixing roller 4, etc. I have weight time.

When the above-mentioned wait time ends and the copy key for instructing the start of copying, which will be described later, is turned on and the microcomputer KWR is loaded, the following process sequence starts.

The operation in FIG. 1 will be explained with reference to the time chart after turning on the power switch SW in FIG. 3.

When the copy key is turned on, the main motor turns on and the potential of the drum is equalized for a predetermined period of time (one rotation of the drum 3).
After cleaning, a latent image forming sequence begins. In other words, the optical path length of the document is determined by the movable reflective mirror 8 that moves in the direction indicated by the arrow in the figure together with the illumination lamp 9, and the movable reflective mirror 6 that moves in the same direction at the moving speed of the movable reflective mirror 8. A drum 30 having a photoreceptor on its surface is exposed to slit light through a lens 17 and a fixed reflecting mirror 18, 19 while being kept equal.
imaged upward. In other words, the document is exposed to slit light while being scanned by the optical system. The surface of the drum 300 has a photoreceptor whose photoconductive layer is covered with a transparent insulating layer. Myosho is charged with electricity. Subsequently, when reaching the exposure section 16, the original on the original platen glass is illuminated by the illumination lamp 9, and an image is formed on the drum 30 by a moving reflection mirror, a lens, and a fixed reflection mirror, so that the photoreceptor is exposed to the original image. A from the high voltage power supply at the same time as
AC by the AC discharger 13 supplied with C high voltage current.
Get static electricity removed.

Then, electrostatic latent scratches are formed on the drum surface (photoreceptor) by full-surface exposure by the full-surface exposure plate 33, and the developing device 3
1: ill is there.

Development is performed by powder development using the sleeve method, and electrostatic latent scratches are visualized.

Next, the transfer material from the cassette 21 or 22 is fed to the paper feed roller 2.
4, the paper is fed by the 10th roller 25 and the 20th roller 28, and is temporarily stopped by the timing roller 29. The roller 29 is rotated by the registration signal FLG, and the paper is conveyed again. matches. The registration signal is obtained from a switch RG that detects a specific passing position of the optical system. Switch 0HPFi Generates a signal indicating the optical system home position (stop position). Both are operated by a cam provided in the optical system (mirror 8) K.

The fed and conveyed transfer material comes into close contact with the drum, and the image on the drum is transferred to the copy material by a transfer charger 27 using a positive high-voltage current from a high-voltage power source.

After the transfer, the copy material is separated from the drum by a separation roller 26, guided to a heat fixing roller 24, and fixed, after which excess charge is removed by a static eliminator 3, and then by a discharge roller.
It is discharged onto the tray 20. Copying is now complete. On the other hand, the surface of the drum (photoreceptor) is pressed and the remaining toner on the drum is cleaned by the nine shields 11, and the next cycle can be performed again. That is, by inputting the number of times of the above-described series of copying process operations from the numerical keys (numeric keypad) K of a keyboard or the like and blit, the above-described cyclic operation can be repeated.

A cam provided on the helmet drum operates switch PF to generate a paper feed signal. Switch DHPFi drum home position (
A signal (stop position) is generated by the drum cam and the drum is stopped at the position where the photoreceptor joint contacts the cleaner 11. 6 23 a + 23 b is a lamp for detecting the presence or absence of paper in the cassette, and a light receiver that receives the light. Element, 2#'

Reference numeral 16 denotes a (1) rank exposure lamp which exposes the photoreceptor to light to eliminate surface potential unevenness when the image side is not illuminated. 7#i is a motor for rotating the fixing roller, 15 is a motor for reciprocating the optical system, and 14 is a lamp for pre-forming light to fatigue the photoreceptor in advance to make it uniform before the process. It is also a pulse generator consisting of an optical detector that detects the plate and its holes when it rotates in conjunction with the 36Fi drum.

M815, 16t; j Three round microswitches each are arranged to detect the presence/absence and size of a cassette. Then, when none of the switches are on, there is no cassette, and when all of them are on, there is no cassette, and when all of them are on, the size is determined by the combination of these on states.
(Selected upper or lower cassette) [The determined size is displayed on the LED, and the speaker generates a statement of the corresponding size only once. If there is no cassette, the same message will be displayed and audible notification will be made.

These utterances are performed when the up/down select key 29 in Fig. 2 is turned on and when the oral key (231 or 233) is turned on. In Jin's case, if it is before the copy sequence starts, he will generate "Please prepare a cassette" only once to stop 7 Beaster F. However, if the cassette in use is removed during the copy sequence, the system will generate the message "Cassette has been removed" several times, complete the nine process cycles that have already been fed, repeat the operation, and memorize the number of remaining copies. Interrupt as usual.

Similarly, when the sensor 23b detects that there is no paper, it selects "Please prepare paper" once, "I ran out of paper" and "4" several times, depending on the time period when it was detected. generate.

When there is no cassette or no paper detected, copying is interrupted and the machine is stopped, and the machine can make a sound for the first time.

A 302Fi search coil detects the current amount of toner by detecting a μ change due to a level change, and outputs a toner empty signal. This also displays "out of toner" audibly.

Reference numeral 301 is a thermistor for detecting the temperature of the fixing roller 4, and when overtemperature is detected, the power supply to the heater inside the roller 4 is reduced by half. A thermistor 300 detects the temperature of the platen glass on which the document is placed, and detects an overtemperature, and interrupts the sequence in the same way as when detecting no paper. 303 is a temperature fuse that detects overtemperature of the lamp 9 and turns off electricity to the lamp. This thermistor displays the weight up book.

201, 202, and 203 are microswitches for sheet detection, and when a sheet is not detected within a predetermined time after paper feeding at each point, the CPU determines that there is a jam, and the 2
In the case of 01, energization to the fixing heater H1 and the DC charger for secondary charging and transfer charging is stopped at the same time as the detection, and the energization to the drum motor and the AC charger is delayed by F11 rotations and then stopped. Thereby, normal sheets can be discharged after the transfer section. In the case of jam detection in 202 or 203, it is determined that there is a paper feeding error from the cassette, and the sequence is interrupted in the same way as in the case of no paper. In the event of a jam in the pick-up/discharge section 2, all electricity is quickly turned off to prevent an increase in accidents.

Say different statements depending on the jam location.

FIG. 2 shows the operating section of this copying lid.

The operator can set the desired number of copies up to 99 on the display 225 by pressing the numeric keys 221 from θ to 9. When you turn on the power, "Fil" is displayed on the display 225. If you are copying only one sheet, you do not need to input several keys.

``CIAR'' key is used when IKing the contents of this set display 225. @C0PY'' key 224Fi
This key is used to copy only the desired value shown on the display 225. Once this key is pressed, the machine performs a copying operation, and when the optical system reaches the inversion position, the display 226 The value is incremented from 0 to +1. A display 226 shows the set value on the display 225 and the number of copies.
When the values match, the copy operation mode becomes the post-rotation end mode≠1≠, and when the copy operation ends and the photosensitive drum stops, the display 226 returns to 101. Therefore, the value initially set using the keys still remains on the display 225, so if you want to make the same number of copies of another document, you can press the "C0PY" key again. During the copy operation, when the count value does not reach the set number, "5TO" will be displayed.
When the P” key 223 is pressed or the display (PEP,
228) When either of the LEDs (Fig. 12) lights up, the copying operation for one sheet at that point is finished, and the process cycle is ended. Therefore, for example, if the above state occurs when the count value is 13 for the set value "6", the display 225 will be 161 and the display 226Fi"

Since "6" and "3" are recalled on the displays 225 and 226, the first operator presses the "COI) Y" key again to make copies of the remaining three sheets.

The display 228° I/l'L' lights up when the "I/R" key is pressed, and goes out when the interrupt copying is completed or interrupted.

When the "8 T 01)" key is turned on after this copy interrupt command, the interrupt can be canceled together with the number of copies.

This key is used to selectively operate only WAIT, and if nothing is turned on, both (warnings will be displayed).

Reference numeral 233 is a key that, when turned on in the case of a jam, instructs the speaker 230 how to clear the jam. Also, if you turn it on before starting copying, it will teach you the copying procedure by voice.

The display JAM lights up immediately upon detection of the jam, and shifts the copying to the end mode depending on the location where the jam is detected, as described above.

In this case, it flashes, and the speaker 230 repeats the statement ``Exit jam.'' until the voice is released. If the jam occurs at the switch 201, the Fi ``It is an intermediate jam'' is repeated several times and the voice stops.

The "TEP" display is turned on by the sensor 302 when the toner in the developing unit runs out, and does not affect the start or continuation of copying. In this case, the speaker 2301C repeats "Please replenish toner" two or three times and then stops speaking.

"pgp"" lights up when there is no paper in the selected cassette, inhibits the start of copying or terminates the continuation of copying, and activates speaker 230 as described above.f1
In the case of jam detection in 202 and 203, #'i "Paper feeding has failed" is repeated two or three times and the machine stops. ``WAIT'' is turned on until the temperature of the fuser reaches the desired value and prohibits the start of copying, but once that temperature is reached, it is pressed to enable the start of copying (exposure) and maintains the enabled state. When the wait is released, Subi-1230 [!S repeats "Copy OK" two or three times and stops speaking. This weight-up is detected and performed by the temperature sensor 301.

229Vi cassette upper (UP) and lower (DOWN)
The selection switch 234 is an indicator of the size of the selected cassette stage cassette.

If a trouble is detected before the copy sequence, when the power switch is turned on and the copy key is turned on, the speaker 230 issues a warning of no cassette, no paper, and no toner with the above-mentioned statement. When copy sequence neutralization is detected, a warning is issued simultaneously with the above-mentioned statement and at a louder volume (3 dB) than before the start of the sequence. Even during a copy sequence, during preprocessing where the process cycle has not yet started after the copy start, the operator is not away from the machine, so the output is made at the same low volume as during non-sequence.

Also, if you turn on the key 233 when a jam is detected, the previous warning sound will stop, and in this case, "Please open the left side door."
, in the case of 201 jam, ``Please open the front door J.
In the case of jams 202 and 203, the speaker is activated to make the user say "Please remove the cassette" once. These statement teachings have a low volume of about 3 dB compared to the warning sound (same as or lower than the warning volume before the sequence starts)
Let's do it.

Further, when a temperature rise of a process load such as a lamp is detected by 300, 301, 303, the set number display 225 changes from the previous value to El, E2, etc. according to the detection sensor. E3
At the same time, the speaker 230 is activated and the message "...is overheating" occurs repeatedly n times and then the system stops. l! During copy sequence/sequence, a warning is issued at a volume 3 dB higher than during non-sequence to prevent it from being drowned out by motor noise during copy operation.

In addition, if the lamp is overheating, the speaker will be activated at a volume 3 dB higher than in other cases to notify you of an emergency. If the clutch that moves the mirror 6.8 reciprocally has a problem and does not return to the home position, it will detect this and issue the same error message and voice warning.

Instead of increasing the plow volume, you can also increase the interval between statement repetitions. It is also possible to configure the volume, number of repetitions, and repetition interval to be selected as desired.

Here, the human input data is inputted and processed according to the execution of the program in the ROM, and is taken into the ACC through specific steps and subjected to logical judgment. The CPtT process then proceeds to the next step, which controls the copying operation load, displays a warning, displays a number, etc.

SC is a voice synthesis unit), l')/DA converter for operating the AFi speaker 230 for forming the above-mentioned statement. The ROM' stores audio data of various statements and allows the designer to create appropriate statements. The data is band-compressed information about the statement voice, and is a characteristic parameter of the statement voice.

The SC performs two operations. First, a feature parameter indicating a statement corresponding to the abnormal location is accessed from the ROM' based on the signal received from the CPU. This is R

Furthermore, the speech synthesis unit (SC) has a digital filter 1, and outputs the digital information of the statement by applying the feature parameters accessed from the ROM' to the digital filter. This is converted into audio through a DA converter. The parameter signal output from the CPU also includes information indicating the volume, and this information fully controls the amplitude of the voltage input to the speaker 230.

The sound can be changed by adjusting the gain of the amplifier a itself using a signal from the CPU 800 without going through the SC circuit.

The audio signal generation filter 805 controls the signal from the white noise generator 806 using the level constant and filter constant from the read-only memory 803, and outputs an audio signal. Presence/absence of sound source information for audio
Three things are raised: unvoiced information, power level, and pitch frequency. The above level constant is a constant for changing the power level, and the filter constant is a constant for selecting the pitch frequency. Therefore, the output from the filter 805 is determined by the level constant and the filter constant. The waveform shown in FIG. 4-4 is obtained. Therefore, by controlling the read-only memory 803 in a time-divisional manner using the outputs of the CPU and the generation timing circuit to change the level constant and filter constant, the output waveform of the filter changes and can be heard as audio. In other words, it becomes the audio signal shown in FIG. 4-3.

For example, if a copy completion signal is output from the detector, the dedicated memory 803 is accessed based on the PH signal from the CPU 800 or the encoder 807, and a string of words that says "copy completed" is selected.

Explain the operation.

When the main switch SW is turned on, it is first determined whether or not the optical system is at the stop position 0fJP, and when it is not tb, the OP is turned on to return it to that position. 0 if it does not return within the specified time
Turn off the Pft, display an error message, and give an audio warning.8 Next, display 01,00 on the displays 25 and 26, and turn on the R
ANK memorize the number.

The on state of the C0PY key and numeric keys is output (output capo)) R
The signals are scanned by time-division signals from o-Rn and dynamically input to 11 input ports. The computer reads the input signal and drives the drum motor. When the drum rotates, a disc 36 rotating in conjunction with the drum motor generates an intermittent optical signal, which is detected by a light receiving element and generates a drum clock pulse. At the drum home position @, when the W signal is generated by the optical detection switch, the paper feed plunger PL is turned on from there.
Start counting 50 drum clocks CP. That is, by inputting the DHP ON signal to the input port 12, reception of the drum clock to the interrupt port IB is started.
1 Let. When a predetermined count is reached, a drive signal is output from the output boat q, the paper feed plunger PL is turned on, the constantly rotating paper feed roller is lowered, and the paper is fed. 50 more after that
The PL is turned off by the clock, 100 clocks are counted from the next old signal, and the plunger OP for driving the optical system is turned on in the same manner as above to move the optical system and simultaneously start exposure. In addition, the turning off of these devices and the operation of other operating devices that require timing are similarly controlled. If T)1-TPK does not return within a predetermined time after the optical system starts, the same optical system error display and audio warning as before the start of copying are performed.

This will be explained in more detail according to the flowcharts in Figures 5-a and 5-1).

First, when the computer starts operating by turning on the power, it specifies a ROM address according to the computer clock, outputs an instruction code, and executes the program in the ROM. In step 2-1, the 1st bit of register Q, that is, 7 bits, is read. In step 2-2, registers 1 to 8 of q
Output the bit to R, ~71. In step 2-3, the input data to the input boat is stored in the accumulator ACC. At this time, since the bird is being output, it is determined whether the C0PY button is on or not based on the input on level to the circle. When the data corresponding to ~3 is stored in ACCK:, the beep corresponding to ~ among them is reached. In the next step 2-4, data specifying the memory RAM address is set in the register DP, and in step 2-5, the data is stored at the address (00) of the RAM specified by that register [N113 figure] in step 2-3. The ACC data is transferred, and in step 12-6 it is determined whether the θ-th bit of the vc data is 1 or not. If there is one, the drum drive motor is turned on via the driver. If the 0th bit is 0 in step 2-6, the flow from step 2-1 is repeated again.

1'' Drum clock counting by the interrupt system will be explained using an example in which 250 drum clocks are counted by 6-a and 5-bA and the signal PL for driving the paper feed plunger is turned on.

In step 3-O, the drum home signal is input.
) Determine whether it is input to I2. Step 3 - IKteR
Code 250 is output from OM and stored in RAM. In step 3-2, set (IK) 7lag B in the flag register of RAM. In step 3-3, interrupt baud) IB interrupt reception is performed. Set the 7 lip flops for the flop, enable interrupts by drum clock pulses, and in the following step 3-4, R,...
A time division signal by set/reset is output from R and I for switching the digits of the display, and a segment signal is output from D to dynamically light up the displays 225 and 226.

This step includes many instruction code steps from ROM code output 1 to output from the output port. The seven light-emitting segments of 225 and 226 display the set number when the key is pressed manually, and each time one copy is completed, the number subtracted by one from that number is displayed. The display is performed intermittently in this step. Reach step 3-4 and step 3
Determine the subsequent state of the flag set with -2, and if it remains the same, wait until the flag is reset. However, when the drum clock is generated during this time, the rise of the pulse against IB [F/F for interrupt reception
The interrupt will be reset manually. Accordingly, another specific address (for example, 100) of the quotient is then set. I(
An interrupt routine program as shown in FIG. 6-a is stored from address 100 of the OM, and is executed at the rising edge of the drum clock pulse. Therefore, the program that was being executed up to that point is interrupted and a drum clock pulse counting program is executed. When the program execution is completed, the address saved in the 5TACK register is set in the counter again, and the main program is executed from the next address.

@6-a Figure is the interrupt routine program. Step 4 - IFi -1 is subtracted from the memory value 250 stored in step 3-1, and in step 4-2 it is determined whether the value has reached OK. Since it is the first drum clock pulse after detecting the drum home signal DHP, it is not O, so skip step 4-3 and proceed to the next step. Set the attached F/F. Then, if the rise of the drum clock occurs immediately before step 3-4 according to the instruction in step 4-5, step 3-4 of the main program
Return to

When the zero-order clock pulse CP that operates the display is input to port B again, F/F' has been set, so the rising edge of pulse CP resets the F/F and starts counting interrupts again. Do a routine.

While doing this, 250 clocks are counted, and when the subtraction result becomes 0, flag B is reset in step 4-3. Therefore, when returning to the main routine, step 3-4 is exited, step 3-5 is executed, output capo)% is set, and paper feed signal PT is turned on.

In this way, the lamp L1 of the other operating equipment. Motor pigeon for drum drive, clutch OP for optical system advancement, -
Secondary charger HV, , Secondary charger HV.

The timing of the clutch CL for driving the timing roller is also controlled.

The signal AFi in FIG. 6-b is connected to the interrupt port 1B and is the output signal of the ninth F/F, and the B signal is the drum clock signal inputted to IB.

FF (signal A) is reset by the rising edge of the FiB signal, and interrupts to the FF (signal A) IB are prohibited.

Further, once the A signal is set by the acceptance command (step 3-3), it is not reset until the rising edge of the B signal is detected. The same applies to boat IA. Also, this is a guide for performing interrupt processing that has a so-called higher priority than the interrupt boat TAFiIB. IAK) Since the trouble detector is connected and the aforementioned clock generator is connected to IB, when the trouble detector detects an accident in the copier,
The speaker z3o and indicator 225 can be activated to issue a warning with a statement appropriate to the location of the problem, and the camera can be stopped.

That is, when the IA and IB F/Fs are set and an interrupt signal is input to the first KIA, the IA and IB F/Fs are reset and the ROM program at the address specified by IA is executed as described above. Clock signal Fi to IB? Not attached. On the other hand, if a clock signal is input to IB first, I
Only F/F of B is reset. Therefore, when a trouble signal is subsequently generated in IA, the trouble signal is input and the copying machine is stopped regardless of whether an IBK interrupt is being applied (drum clock CL input).

Figure 7 shows that when it is determined that the main switch 8w is turned on, the F/F of 5TEPIK and IA is set, and 5TBP is set.
2 is a flowchart in which the input of a copy key is determined in step 2, and steps 3 and subsequent steps for clock counting described above are executed to complete the process of copying a predetermined number of sheets. Accident signal X
If this occurs at any step in this process cycle, that step is interrupted and the interrupt flow of IA-8TART is executed. off,
El etc. are displayed on the display 225 and the display is held.

This turns off the operation of the copying machine (drum motor M, front lamp L11, various clutches CL). After taking safety measures against this accident, the position of the operating piece of the reset button 500 that latched the copy restart prevention is pushed back to the position where it can be restarted, and the speaker 230° indicator 225
The warning behavior will be reset. It is also possible to reset by determining whether the switch 501' is closed, which is linked to the switch 501 that is activated when the national sports stadium door is opened. In this case, the warning display on the display 225 remains until the button 500 is turned on.

By the way, the IA flag is not reset unless the SW is turned off, so trouble monitoring can be performed regardless of sequence or non-sequence. Also, if a large IA input is detected before the copy key-on judgment in step 2, the output from the speaker 230 will be 3 dB compared to when it is detected before reaching the END step.
Control the constants of the voice synthesis unit (8C) to make the voice sound at a lower volume.

(2) If the IA input is detected before the CPU determines the IA, the speaker 230 is operated at a volume 3 dH lower. Also, step END when a predetermined number of repeat copies have been completed.
After executing this, if IA input is detected, the volume will be lowered by 3 dB.

Also, if a trouble signal was input to the IA in the previous cycle and the speaker 2%) was latched and the statement was being repeatedly uttered, the volume of the same statement on that O is changed at the same time as the side step is executed. Reduce by 3dB.

In addition to or in addition to the volume control described above, it is possible to lengthen the statement repetition interval or change the sound quality, that is, the statement content.

This makes it possible to prevent as much noise as possible from disturbing third parties in the office.

Here, examples of the accident detection circuit include a detection circuit 301 for detecting abnormal temperature inside the copying machine (inside the fixing device), a paper ignition detection circuit, and a detection circuit 300 and 303 for the exposure means. It is also possible to use a device that detects paper jams in the transfer paper in the cassette and the absence of developer (Fig. 1, 23a, b), and an external dedicated circuit or cassette that detects jams (paper jams) in the transfer paper path. This can also be done with an external dedicated circuit that detects errors in paper feeding. If a circuit that detects a paper jam or a paper feed error is connected to the interrupt board, the occurrence of a detection signal for a jam or paper feed error before the transfer unit will cause
It is preferable to stop the drum in a state where the surface charge is removed by moving the can to a post-rotation cycle of the drum immediately before the end cycle, and to issue an audible warning after the stop. As an example of the same paper jam detection circuit, a timer is activated at the start of paper feeding, and within a predetermined time (timer), the paper detector 2 at the exit of the passage is detected.
(Fig. 1) resets the timer when it detects paper, and uses the timer output as the detection signal when it does not detect paper, and uses the timer output as the detection signal when the paper does not pass through detection Wk2 within a predetermined time (another timer). This becomes possible.

In addition, the paper feeding error detection circuit operates a timer when paper is fed, and when a nine paper detector (not shown) does not operate within a predetermined timer period, the timer output is used as a detection signal. There are devices that detect line feed and use it as a signal.

The warning signal from the CPU is information for the audio output circuit to generate audio corresponding to the abnormal operation. Therefore, when the SC of the audio output circuit receives the signal, it performs two operations. One is R, which stores characteristic parameters of statements to be uttered in response to various abnormal operations.
From IM'803, based on the signal output from the CPU,
The key is to access the appropriate statement feature parameters. The % characteristic parameter is a characteristic parameter obtained by band-compressing the voice of a statement, and refers to a parameter representing pitch frequency, power spectrum, voiced sound, unvoiced sound, amplitude, etc. On the other hand, the characteristic parameter The SC that has extracted the statement creates digital information of the statement voice using a digital filter or the like based on the characteristic parameters, and sends this digital signal to the next D/A circuit 802.

The digital signal is converted into an analog signal by the D/AFiD-A converter, amplified by the next-stage h amplifier, and output to the speaker 230. Therefore, the speaker outputs the voice of the statement based on the characteristic parameters. From the above, the characteristic parameters stored in Rm'K, in other words, the statements, can be freely set by the designer, and in response to each abnormality warning, an appropriate statement can be set in a manner that is easy for the user to understand. It is possible to create

Now, when an abnormal operation is detected by the abnormality detection means for the copying process described above, the CPU 800 outputs a signal to interrupt the copying process from the port q through program processing as described above, and then sends a signal to the operator. In order to warn, a signal is sent to 801 of the speech synthesizer 8C. This signal also includes a signal indicating a statement corresponding to the location where the abnormality has occurred, and a signal instructing to increase the volume during the copying sequence and to decrease the volume before and after the copying sequence. The audio circuit that receives this signal performs the operations described above, and outputs a statement audio corresponding to the location of the abnormality from the speaker 230, and with different volumes depending on whether during the copying sequence, during the cycle, or before and after the copying sequence (see Fig. 8). ). The acoustic circuit also generates a statement indicating that the copy operation can be started for the weight-up straight edge (FIG. 9).

FIG. 8 shows the assumption that the lamp has now overheated under the control of the interrupt program IA [FIG. 7]. The IA program is executed using the signal from the thermistor 303. In step 1, a cycle flag indicating a relationship formation process sequence is determined. This flag is set in the DHP determination step of FIG. 7, and is one area of the sea bream that is reset upon detection of the stoppage of the optical system in the last cycle at the end of a predetermined number of repeat copies. In other words, it corresponds to the time period excluding drum pre-processing rotation and post-processing rotation. The processing rotation time corresponds to the number of rotations of the drum necessary for cleaning the entire surface and removing static electricity. When human input to the IA is detected in a band other than these, an appropriate statement is uttered at a predetermined volume. When a statement is uttered once, a statement counter provided in RAMK is incremented by 1. After repeating the statement output a predetermined number of times, the CPU outputs the statement to the audio circuit 801.
Cut the output from 800 and stop vocalization. The warning is loud and short, so you can get anyone's attention. Note that since the CPU does not cause a program interruption during voice execution, the voice can be generated correctly.

When it is not a cycle, the copy flag is determined (step 2). When it is determined that the copy key 221 has been turned on, this flag is set to another area of the lake, and the second
It is reset when the step is reached. Therefore, when it is determined that this flag is set, it is assumed that a front and rear rotation neutralization accident has occurred, and the same statement is uttered only once at a lower volume than during the cycle.

This takes into consideration the fact that the operator is not far from the machine.

Next, the copy flag is in a reset state, that is, standby,
If there is a problem in the weight band, as in step 3, the voice is uttered 3 dB lower than during the cycle, but only four different statements are uttered repeatedly. Then, the output of the audio circuit 801 is latched to be outputted repeatedly until the door switch 501 is opened. This makes it possible to recognize trouble conditions even if the machine is left on standby in a deserted place with the SW on.The same applies when the sensor 303 detects a leopard line on the lamp. Each person says a statement that identifies the problem. Helmet, optical system clutch OP
The above-mentioned trouble detection signal 4 is input to the IA, and in the same process as shown in FIG. . When the wait is increased according to the signal from the sensor 301, an appropriate statement is output, and the statement timer provided in Wvl is turned on. This timer determines the repeat output timing, and is determined by counting a predetermined number of micro clock pulses that cause the CPU 800 to run. Output the same statement again on count up. If the copy key is turned on during or after this time, the copy cycle shown in FIG. 7 will begin. With this K, it is possible to teach that copying is possible with the minimum necessary sound. For this purpose, the number of utterances can be at least one time.

Next, control according to the object to be detected and the location will be explained with reference to chart 70 in FIG. First, when an abnormal operation is detected during the copying process, a detection signal is input to the IA, and in this case, the abnormality detection flag is set to 1. The abnormality detection flag is monitored by a program using the drum clock of the copying machine as a timing signal.

When it is detected that the abnormality detection flag has become IK (step 1), the program branches from the copying process routine and determines whether the abnormal operation is A or B (step 2).
, 3), this judgment is for one person boat (4 or 8 bits)
This is done by checking the bits of A and B.
Danger [K] is ranked according to K, and abnormal operation means a trouble with an extremely high degree of danger, such as a jam near the fixing heater, overheating of the heater, or paper stuck to the drum. To tell. Abnormal operation B means a low-risk problem, such as a paper feeding error or a jam near the transfer area.

This includes platen overheating. Therefore, A can be determined by determining 2°301 connected bits, and B by determining 1 of the bits connected to other sensors.

Then, the copy process interruption operation is made different depending on the abnormal operations A and H. For example, when an abnormal operation is detected by the abnormality detection circuit ranked as abnormal operation A, the abnormal operation is extremely dangerous, so the copying process interruption routine All units are shut off. In addition, when detecting an abnormal operation ranked as abnormal operation B by the abnormality detection circuit, the risk of overprinting is not high, so the fusing heater, etc. is not shut off, and the copying process is performed after post-processing is performed to stabilize the process. will stop. If the person acting abnormally is detected, the input seconds of the Cisco key will not be activated unless the reset button 500 is turned on, but in the case of B, copying becomes possible once the abnormal condition is corrected.

After determining whether the abnormal movement is A or B in Figure 1O, if it is determined that the abnormal movement is caused by a person, after passing through the copying process interruption routine, which of the abnormality detection circuits detects the abnormal movement? A determination as to whether or not it has been detected is made by further bit determination as described above. If an abnormal operation is detected and it is determined that this is a jam or overheating of the fixing roller, the corresponding voice of statement 1 will be repeatedly output and the segment display 2 will be displayed.
Display 25 K E 1. Also, since it is operating abnormally, the volume is increased.

Then, the audio output is latched until the opening of the door switch 501 is detected. Detects that the reset button soo o is turned on and returns the display of 225 to the number of sheets display. In cases other than the above-mentioned abnormal operation, the same operation is performed and B2 is displayed on the display 225.
Because the second ring is overheating or there is a jam in the transfer section, cancel the audio latch using the clear key or stop key.

Since B is not very dangerous, the volume is reduced by 3 dB. In the case of detection 2, the statement is repeated a predetermined number of times and then stopped, but in other cases (such as no toner due to 302VC), the statement interval is lengthened and output. Detection 2: No paper, no cassette, and overheated platen.

Copy the above from step l. You can also set it up in your pre-start routine and always check it.

By using the above-mentioned audio warning means, it is possible to more reliably notify the operator of an abnormality in the copying process, compared to the conventional light-emitting display means.

Note that FIG. 11 is an example using an interrupt port, and any signal from each sensor causes a jump to the flow as shown in FIG. 7, and the determination as described above is repeated.

In the case of still low-rank anomalies, monotonous acoustic waves (e.g. tKHz
) can also be done. The CPU is key 221~

0 is activated, but when a low-rank trouble occurs, the sound can be made to be the same as this key-on sound.

Next, 1. The ED display and audio warning means will be explained. As shown in FIG. 12, draw a schematic diagram of the copying machine and mark the parts of the display board 600 in FIG. 2 that correspond to the locations where the abnormality detection circuits are installed with different colors depending on the abnormality rank. Attach and set D. Therefore, CPU so
From o, there is an LED corresponding to the position where abnormal operation was detected.
A signal that causes the LED to emit light is output to port 6, thereby causing the LED to light up. In addition, rounding and high rank (Figure 10 LED 22) make it easier for operators to detect abnormal operations.

The pattern of the ED 225 and the LED shown in FIG. 12 are displayed and blinked at the same time as above in correspondence with the abnormal location. 12th
The old part of the figure corresponds to each sensor position in FIG.

In FIG. 13, when the key 231 is turned on during initialization such as the above-mentioned wait, cleaning rotation, and optical system reset to bring the optical system to α after 8W is turned on, only the SC flag is set and only the audio is selected. When the key 232 is turned on, 1. Select only BD. The initialization routine accepts key entries from the numeric keypad. keys 231, 2
Set the SC flag and LMD flag to 7N by turning on 32. If nothing turns on, set both.

Change the flag using the clear key.

Next, as mentioned above, by inputting the trouble signal, 7 in FIG.
Execute 0-. First, it is determined whether the warning is to be output by voice or by the old display.

This is done by determining the previous 7 lags (steps l, z)
In the case of flag 5C-Jt set LBD folder reset, audio output is selected, so an appropriate signal is sent to audio synthesizer SC. In the voice synthesizer, the above-mentioned processing is performed, and a statement or voice with a volume corresponding to the abnormality PjTK or Mullen condition is output to the speaker 23.
Output from 0. Similar processing is carried out in the LHDi display means (step 3), and these flags are directly reset to the key after each series of copies, and the green flag is automatically set when the desired copy is completed. be done. Also, if you want to return to 1' when the copy key was set, you can reset it using the clear key.

As mentioned above, since there is a warning means using the j■ display and a cost notification + stage using voice output, the operator's preference and
It has the advantage of being able to be used differently depending on where it is used.

FIG. 15 is a flowchart showing voice control of the abnormal geographical means using the check key 233 of line 2.

The trouble is determined as described above, and the input port It of the microcomputer is periodically sensed to read the cassette Trsf.

etc., are periodically determined (step 1), and then the type of trouble is determined (steps 2 to 4). Then the speaker is output.

Thereafter, it is determined whether the clear key C has been pressed to stop the warning (step 5). If the abnormal operation is canceled by the warning stop key, the process does not continue. Also, if the warning key C is not pressed, the check key 233 is used to instruct how to check whether the check key 233 has been pressed or not. When the check key is pressed, the warning up to 7th is stopped and the CPU outputs the 46 procedure as a voice.
Sends a signal to the audio output circuit SC 0 In the figure, statements 1-a, statements ;/) 1-b...statements) 1-n are the ones. Different statements such as "Please, please" and "Is there paper stuck inside?" are sequentially output as voices after a certain period of time. Also, depending on the location of the abnormality, different sound waves and different intervals are used as described above. The operations described above are performed similarly in all anomaly detections.

In the case of trouble n, only 1 is lit and no voice is output, but this key 233 can be used to utter a request for processing j=. For LEL)β), the above-mentioned teaching routine can also be provided by replacing Y and Ni in step 5 even after the sound is stopped by pressing the clear key corresponding to TIP.

This can prevent unnecessary voice teaching.

It teaches 21g1 once every time the direction check key IN is turned on, so it is better not to repeat the same statement more than 3 times, and each step in Routine 2 does not require you to remove the cassette or open the door. detects it at 9 and utters I- what to do next. Even if there is no jam, if you open the door while the machine is powered on, it will detect this and open the door once.

FIG. 16 shows a control in which the same voice statement is repeated a predetermined number of times and automatically stopped, and the number of repetitions is arbitrarily preset using the numeric keypad 221.

First, in the excitation Φ step when the copying process is completed, in order to output a statement indicating the completion of copying of the type ``copying is complete'', a signal having information on the statement is outputted from the CPU to the audio output circuit SC. Then, the statement counter in the RAM is incremented by 1 to count the number of times the arm arrangement signal is output. The count number is compared with a preset number of nine counters (this number is stored in the statement counter memory area of the application in step 2 using the numeric keypad 221), and if the count number is less than the set number, If it is smaller, it outputs the audio again, and if it is the same, it stops the audio, resets the sound, and
Returning to process initialization, the abnormality is removed and the program 2
The system executes a routine that monitors the copy start key and waits until copying is possible.

Setting the counter memory 8MK number can be done by turning on the check key 233 twice in succession and turning on the numeric keypad 22.1. If you start copying by turning on the copy key without turning on key 233, ROM1 will be automatically copied.
l (Storage n is set in the counter memory. This applies not only to the end of copying, but also to all statement voice outputs that notify the operation, copyable status, etc.

Any mistake in inputting the number of returns can be corrected by turning on the check key 233 again. The same applies to changing the set copy number after the sequence ends. It can also be corrected using clear key C.

By the way, you can use the same method to preset the length of the timer that determines the repeat interval for the same statement using the numeric keypad. Note that a timer can be used instead of a counter to determine the duration of the audio.

Furthermore, if the utterance of "Copy India" is performed once only when the desired number of copies is reached or more, the noise will be reduced. That's the first
This is done according to 70- in Figure 6-2.

In addition, the total number of copies that are not cleared is counted externally, and when the number reaches a predetermined number, the photoconductor is replaced.
By inputting the CPUK signal, a voice warning can be issued by the IA program.

Incidentally, abnormalities in high-voltage power supplies due to breakage of corona discharge wires or destruction of transistors do not usually exist in places where operators can visually and intuitively judge them, and there may be multiple types of abnormalities even for the same target. Often causes considerable damage.

Figure 17 shows how to take appropriate measures in response to each of multiple abnormalities.1 For example, when controlling the temperature of the fixing heater at a constant level using the thermistor SOO, it is necessary to check whether the voltage is abnormal or the mister is disconnected or short-circuited. There are various abnormalities. Therefore, the microcomputer 800K detects and inputs the signal through the converter 80s which decodes and sends the signal to each line of the input port I2[) according to the '&'. Is the converter 805 sen? This is a type of Φ converter that converts signals indicating the types and degrees of various abnormalities obtained by CPU 800 so that they can be deciphered. The CPU 800a compares it with a predetermined reference value, and if it determines that there is an abnormality, it outputs a signal corresponding to each abnormality to the speech synthesis circuit 8CK.

FIG. 18 is an example diagram of the control flow. This is a case where one bit of the input port 4 or 8 of the input port 805 is set to 1 depending on the type m of the abnormality detection signal.

In other words, when it is sensed that any bit of input/-) I3 is set to 1, the first

3 and determines that the first bit is set to 1 (step Immediately stops Mac/ (stepping). When the second bit, third bit, etc. are determined to be 1, statements 2, 3, etc. are uttered with a pause in the repetition interval at F13 dB lower. And LED
t-A large number of lights can be arranged to indicate the degree of abnormality, and the number can be selected by lighting up in synchronization with the abnormality determination.

In FIG. 19, when the power of the copying machine is turned on, the copying process is initialized, such as resetting the power supply circuit and forward rotation of the drum (step 1).

In this situation, for those who are using the copying machine for the first time, a voice confirmation means is provided before starting copying. In the above-mentioned state before starting copying, if the operator presses the check key 233 provided in the operation section of FIG. 2, it is determined (step 2) and the statement output routine is executed. 3゜4
Branch to. And statement D-a.

Statement D-b . . . 9 statements are output aloud. tbWhen the check key 233 used in the event of an abnormality is pressed before copying starts.

The copying machine will output statements such as ``The number of copies has been set.'' ``Specify the paper size.'' (Step 4). After executing check key 23 again.
30, outputs "Please press the copy key" (step 3). In addition, as in the case of abnormality treatment, the sound is uttered once or twice each time the check key 233 is turned on.

Figure 19-2 shows that when the guide key 233 (also used as a check key) is used to output a number-related statement (P-a), the size-related statement waits for the numeric keypad 221 to be operated. )P-b
appears once.

If the numeric keypad 221 is not operated within a predetermined time, P-a is output again and p-b is output.

Figures 1Q-1 and 19-2 are variable-magnification copying machines, color copying machines,
The trimmable copying machine can be operated extremely easily.

In each of the following examples, the voice data in Figure 4-1 is prepared in advance so that the statements can be written in either Japanese or English, and the switching (not shown) is performed. Make sure that the desired selection is made by pressing the switch)! ! The machine can also be equipped with a dedicated key switch that outputs all warning statements, guide statements, or words stored in ROM' for speech diagnosis.

When using this key to make a sound, copying cannot be started even if - is turned on during copying.

The copy machine in this example also has <Kits.

As shown in Fig. 19, if the ear 7 on jack 900 is provided and the ear 7 on is set in the jack 900, the statement of the jam processing procedure or copy operation procedure can be output from the ear 7 on alone without operating the speaker. . In addition, 9 noise can be prevented. In this case, even if a jack is inserted at any time during the copy sequence operation shown in FIG. 3, the audio line can be switched without interrupting the copy operation.

FIG. 20-1 relates to prevention of forgetting to turn off the power of a copying machine or the like.

This embodiment can also prevent forgetting to turn off the power of a facsimile or other electrical appliances such as a hair dryer or a washing machine, or forgetting to turn off the power of lights in a car or the like. The following is a case where a statement voice is generated, but the same configuration is used when a simple warning sound such as a buzzer is generated.

The middle part of the figure shows a switch to turn on the power to rotate the main screen as necessary to enable the operation of the copying machine, and a switch to open and close the bacterial cell or J [II cover 10 of the copying machine shown in Fig. 1]. If the switch that turns on and off is a door switch, turning it off turns off the high voltage. Computer fi800 (20th WJ>F1 Sweets fMsN, DS
The power does not turn off even if W is turned off.

401! -1 is a photosensor such as a phototransistor that detects external light around the copying machine, and its output changes depending on the intensity of the light. Other numbers are the same as shown in FIG. CPU H When you forget to turn off the power, select the statement data from ROM'. Output the address data in accordance with the timing of the voice generation. In this example, the corporate voice ■ is ``Please turn off the power switch.'' Say "The power switch has been turned off."

Figure 21-1 is a front view of the copying machine, with broken switches N,
DSW, sensor 40! -1 arrangement is shown.

A hemispherical semi-transparent glass 403 is provided to increase the sensitivity at t-1 and to make it non-directional.

The operation will be explained with reference to the O control flowchart in FIG. This flow is stored in the CPU's program ROMK, and is configured to execute the program from the start by turning on the power (+V) to zero. This + terminal is connected to a battery or an AC connector. First, if the number of voice repeats is required, set it to ntnl or n2. This is done using the numeric keypad to set the number of copies and returns. If nothing is done, l is set (step l) 0 Next, it is determined whether the door switch or origin fktJ bar switch is open. Before Door Switch Copy,
The determination is made during the copy interruption, and the cover switch is determined after the copy is completed. It inputs the signal that detects the state of the switch to the CPU and makes the CPU judge. D8W
When the main switch MSW is off (open), it is determined whether the main switch MSW is closed or not (3).This is done by similarly inputting the MSW state detection signal to the CIU and causing the CPU to make the determination. This signal is a level-down version of the DC power turned on and off by D8W and MSW. When the main switch is on (closed), the input of the external light sensor 402-1 is determined (4). In the case of auto-shut after a jam, it is better to judge the door switch, and for auto-shut after copying is completed, it is better to judge the company cover switch. In the former case, the flow shown in FIG. 22 is executed when a jam occurs, and in the latter case, the flow is executed while the motor is stopped.

A good signal detected by the external light detection sensor 402-1 is ~
It is processed by the Φ converter 402-3 and converted into a digital signal. The output from the is sent to the CPU that controls the copying machine, and it is compared with a certain reference value, and when the brightness is lower than that, a signal is sent from the output terminal of the CPU to the nozzle, which is used for voice synthesis. Output to the Lsi (5), the speech synthesis Lsi4 accesses the 4I characteristic parameters of the appropriate statement based on the signal output from the 0PU3 from the ROM' that stores the characteristic parameters of the created statement. do.

The characteristic parameters are unique parameters obtained by band-compressing the voice of a statement, and are parameters representing pitch frequency, power spectrum, presence of voice, no voice, amplitude, etc.

Next, the speech synthesis Lsi uses a digital filter or the like to generate digital information of the statement speech based on the characteristic parameters and sends it to the %V person converter.
The D/A converter converts the digital signal into an analog signal, outputs it to the next stage amplifier, and drives the amplifier speaker 230. Therefore, the speaker 23G outputs a voice statement based on the characteristic parameters.

Sen+402-1 is installed near the original glass stand,
Detects whether the brightness changes when the exposure 2nd ring is turned off,
K so that it can be determined that the copying is complete. Return to the routine for determining bright Sekihiro DSW and MSWt.

After repeating the previous output ■ for the set number of times n, the output of ■ stops, and a warning of ■ is output instead (7) to notify that the power will be forcibly turned off.

During this n number of warnings, turn off the main switch. It is time to cancel the warning and return to the original routine.

■Forcibly shuts off the main switch after the warning.

Figure 21-2 is a layout diagram of a car's power switches, especially switches and sensors to prevent headlights and other lamps from being turned off, where D is the door, DEW is the switch that turns off the door, and B is the bumper. In this case, a photo sensor is placed near the headlight as 402-1.402-2. By using the MSW as a lamp switch, the above-mentioned forget-to-turn-off prevention control can be performed using the same flow as shown in FIG. Note that the above can be done by providing a microphone instead of a photo sensor to determine external sounds.

By the way, to open the door during copying, when the door switch is turned off, "first door open" can be displayed by voice and displayed by LED. This can be done by canceling step 4 as shown by the dotted line in FIG. 22, and using a flow in which ``■'' in step 6 is changed to ``■'', and periodically executing this flow during copying. Also, before copying and after copying is complete, a different display can be made with the sounds ■ and ■.
