Next, an electric circuit for drive control when the above-mentioned motor is used as a drive means for winding and rewinding the tape W coated with the processing agent and the photographed film F will be explained.

FIG. 4 is a block diagram schematically showing this electric circuit.

First, the power supply circuit 1 will be explained. In this embodiment, power for driving the motor M can be supplied from either a household outlet or a battery. Changeover switch SW ₁
If you connect it to terminal a, it will connect to a household outlet.
If a DC voltage obtained by rectifying AC100V is connected to terminal b, the voltage from the battery will be applied to the output switch _SW3 . When the above-mentioned lid 12 is closed, the door switch SW ₂ is turned on, and the output switch SW ₃ is connected to, for example, the terminal a, so that a power supply voltage is applied to each circuit section of the control circuit.

Battery check circuit 1A in power supply circuit 1
is a circuit for checking and displaying the battery voltage when a battery is used as a power source.

By connecting the output switch SW ₃ to the terminal a side, the reset circuit 3 is activated, and the bistable multivibrator (hereinafter referred to as FF) and monostable multivibrator (hereinafter referred to as MM) used in the control circuit is activated. ) and initialize it.
Q output of each FF and MM is “L”, output is “H”
shall be. The motor M is now ready to be driven.

Here, when the operation circuit switch SW ₄ for driving the motor M is turned on, the operation start signal circuit 5 in the motor drive control circuit 4 is transmitted to the motor drive circuit 6.
A motor drive signal is issued to the motor M, and the motor M starts rotating. That is, an AND circuit connected between the operation start signal circuit 5 and the motor drive circuit 6
AND is provided to stop the motor M when a signal is issued from the operation end signal circuit 7 in the motor drive control circuit 4, but initially no operation end signal is issued. , motor M
starts rotating and starts winding up the processing agent application tape W and the film F.

At this time, the operation display circuit 2 receives a signal from the motor drive control circuit 4 and displays winding.

When the winding of the processing agent coated tape W and the film F is completed, the winding completion detection circuit 9 detects the motor rotation direction indicating circuit 1 based on the output from the rotation detection circuit 8.
0, the motor rotation direction indicating circuit 10 outputs a signal to the motor drive circuit 6 so that the rotation direction of the motor is reversed to the winding direction, and also outputs a signal to the timer 20 to indicate that the rotation direction of the motor is opposite to the winding direction. give a signal. When the timer 20 receives this signal, it issues a signal to the motor drive circuit 6 to stop the rotation of the motor M for a predetermined period of time.

The operation display circuit 2 displays a stoppage signal based on a signal sent from the timer 20 to the motor drive circuit 6 indicating that the rotation of the motor M has stopped.

The motor M stops rotating in response to a rotation stop signal from the timer 20, and starts rotating again in response to a signal from the timer 20 after a certain period of time has elapsed. At this time, the rotational direction of the motor M is opposite to the winding direction since the motor rotation direction indicating circuit 10 generally outputs a signal that is reverse to that at the time of winding when winding is completed. As a result, the motor M rotates in the opposite direction to that during winding, so the processing agent coated tape W and the film F are rewound.

Even when rewinding, the signal from the timer 20
The operation display circuit displays rewind.

When the rewinding of the processing agent coated tape W and the film F is completed, a signal is output from the rewinding end detection circuit 21 to the motor rotation direction indicating circuit 10, and this signal causes the motor rotation direction indicating circuit 10 to in turn control the motor drive circuit 6. On the other hand, the signal that outputs a signal to rotate the motor M in the opposite direction to that at the time of rewinding is simultaneously input to the operation end signal circuit 7, and when this signal is input, the operation end signal circuit 7 starts the motor drive circuit. By outputting an operation end signal to the AND circuit AND between 6 and the operation start signal circuit 5, the rotation of the motor M is stopped and the operation end buzzer circuit 22
signal and sound the buzzer BZ.

When the buzzer BZ sounds, it can be known that the film F has been processed with the developer on the tape W, and by opening the lid 12 and taking out the film F, all operations are completed.

In this block diaphragm, the winding end detection circuit 9 and the rewinding detection circuit 21 are configured separately, but in this embodiment, the winding end detection and the rewinding end detection are performed based on the rotational speed of the motor M. Since this is done by measuring , a single monostable multivibrator is used.

FIG. 5 shows an example of a specific electric circuit constituting the circuit of FIG. 4.

This electric circuit consists of a power supply circuit 1 for supplying power to each part, a reset circuit 3 for initial resetting the flip-flop (FF) and monomulti (MM), a motor M, and a motor M for driving the motor M. The motor drive circuit 6 includes a motor drive control circuit 4, a motor rotation detection circuit 8, a motor rotation stop detection circuit 23, and an operation display circuit 2.

First, the power supply circuit 1 will be explained. When the lid 12 of the photoconductor processing apparatus is closed, the door switch _SW2 is turned on, and a power supply voltage is applied to one terminal of the output switch _SW3 . When the output switch _SW3 is turned on, a voltage is applied to the base of the transistor _TR1 , the transistor _TR1 is turned on, and the power supply voltage is applied to the lead line l. When a voltage is applied to the lead wire l, the reset circuit 3 is activated, and an initial reset is applied to each of the above FF and MM.
The outputs of each FF and MM are "L" for Q and "H".

Here, when the operation start switch SW ₄ for driving the motor M is turned on, a motor operation start signal is sent to the FF ₁ of the motor drive control circuit 4 via the NOR 2.
An "H" input is applied to the input terminal CP of. FF ₁
When an "H" input is applied to CP of FF1, the output Q of _FF1 becomes "L", which is applied to input terminal 1 of NOR1. Input terminal 2 of NOR 1 is connected to output Q of FF ₃ , and since FF ₃ is initial reset, its output Q is "L". Therefore, the output of NOR1 becomes "H", and this output is applied to input terminals 1 of AND1 and AND2 via resistors _R4 and _R5 . Input terminal 2 of AND2 is connected to the output of _FF2 , and since _FF2 is also initial reset, the output is maintained at "H", and this "H" is connected to the input of AND2. The output of AND2 becomes "H" and transistor _TR7 is turned on. When transistor TR ₇ is turned on, the transistor
The collector of TR ₇ is short-circuited to ground, and the base voltage of transistor TR ₃ connected to the collector of transistor TR ₇ becomes "L", turning on transistor TR ₃ .

On the other hand, the output “H” of MM 2 is applied to the input terminal 1 of NAND 1, and the output “H” of MM ₂ is applied to the input terminal 2 of NAND 1.
is connected to the input terminal 2 of the AND2 mentioned above, so the output of _FF2 is applied "H", the output of NAND1 becomes "L", and the transistor _TR8 connected to this output is turned off. Become. When the transistor _TR8 is off, the voltage at the collector of this transistor _TR8 is "H";
is added to the base of transistor TR ₄ , and transistor TR ₄ is turned on.

In this way, the transistor of the motor drive circuit 6
When TR ₃ and TR ₄ are turned on, current flows through the motor M in the direction of the arrow and it starts rotating. When the motor M rotates, the processing agent coated tape W and the film F are wound up in an overlapping manner.

When winding of the processing agent-coated tape W and the film F is completed, the rotation of the motor M is braked by the tension of the processing agent-coated tape W and the film F, and the motor M is stopped.

In this embodiment, the rotation of the motor M is detected by attaching an encoder to the rotating part of the motor between the light emitting element LED ₁ and the light receiving element PH ₁ , and measuring the pulse interval of light incident on the light receiving element PH ₁ . It's summery. Rotation can also be detected in other ways, for example using magnetic sensors. Also, patrone axis 2
It may be detected by the overload detection mechanism provided in 1.

T ₁ of MM ₁ of motor rotation stop detection circuit 23 and
A capacitor C ₁ and a resistor R ₁ are connected to the T ₂ terminal, and the capacitor C ₁ and resistor R ₁ constitute an integrating circuit.

Input terminal B of MM ₁ is connected to output Q of FF ₁ , and the output of FF ₁ outputs "H" when motor M is rotating. The operating state is maintained only when

When the motor M is rotating, the input terminal A of MM ₁ is connected to the light receiving element PH ₁ by the encoder.
However, when the motor M stops rotating, the pulsed light no longer enters the light receiving element _PH1 .

The output Q of MM ₁ is “H” when the interval between pulses applied to input terminal A of MM ₁ is shorter than the time constant determined by the values of capacitor C ₁ and resistor R ₁ that constitute the above-mentioned integrating circuit. However, when the interval between pulses applied to input terminal A becomes longer than the above-mentioned time constant, it becomes "L". MM ₁
When the interval between pulses applied to input terminal A becomes longer than the time constant, the processing agent coated tape W
It is determined that the winding of film F is completed, and
The output Q of MM ₁ is set to "L" and is set to "H".

Even if the output Q of MM ₁ becomes “L”, capacitor C ₄ is connected to Q through resistor R ₆ ,
The voltage at input terminal 1 of AND3, which is connected via capacitor _C4 and resistor _R7 , remains "H" even if the output Q of _MM1 becomes "L" for a short time.
There is an input. Input terminal 2 of AND3 has
Since “H” from the output of MM ₁ is input,
AND3 outputs an "H" pulse output only while input terminal 1 of AND3 maintains "H".

When the output pulse of AND3 is applied to the input CP of FF ₂ , the output of FF ₂ is Q becomes “H”,
Q becomes "L". This _FF2 is a flip-flop provided to reverse the rotational direction of the motor M.

Since the output terminal of FF ₂ is connected to the input terminal B of MM ₂ , it starts operating when it changes from "H" to "L", and the capacitors connected to terminals T ₂ and T ₁ of MM ₂ The output is inverted to "L" for a certain period of time by a time constant determined by the values of C ₂ and resistor R ₂ . This MM ₂ is provided to adjust the time from when the motor M winds up the processing agent coated tape W and the film F until it starts rewinding, and is connected to T ₁ and T ₂ . The time can be adjusted by changing the values of capacitor C ₂ and resistor R ₂ .

When the output of MM ₂ becomes “L”, the input terminal 1 of NAND 1 connected to this output becomes “L”
Therefore, the output of NAND 1 becomes "H". When the output of NAND 1 becomes "H", transistor TR ₈ turns on, and the base voltage of transistor TR ₄ changes from "H" to "L", and the transistor TR 8 turns on.
TR ₄ is turned off. By turning off the transistor _TR4 , no current flows through the motor M, and rotation is stopped.

Then, after a period of time determined by the values of capacitor C _{2 and} resistor R ₂ connected to T ₁ and T ₂ of MM 2 has elapsed, the output of MM ₂ outputs "H" again.

When the output of MM ₂ outputs "H" again, the output of FF ₂ , which is provided to reverse the rotational direction of motor M, is "H" because Q is "H". is applied to the input terminal 2 of AND1 and the input terminal 2 of NAND2, and AND1 becomes “H”
output, and NAND 2 outputs "L".
When the output of AND1 becomes "H", the transistor TR ₆ is turned on, and when the base voltage of the transistor TR ₂ connected to this collector becomes "L", the transistor TR ₂ is turned on. Then, when NAND 2 applies an "L" output to the transistor TR ₉ , the transistor TR ₉ is turned off, "H" is applied to the base of the transistor TR ₄ , and the transistor TR ₄ is turned on. By turning on the transistor TR ₂ and the transistor TR ₄ , the current flowing through the motor M becomes opposite to the direction of the arrow, the motor M rotates in the reverse direction, and the processing agent coated tape W and the film F are rewound.

When the processing agent coated tape W and the film F are finished being rewound, as explained at the time of winding, the rotation of the motor M is stopped and the motor rotation stop detection circuit 2 is activated.
Input A of MM ₁ of 3 is connected to motor rotation detection circuit 8.
There is no longer any pulse input from , the output Q of MM ₁ becomes "L", and becomes "H". At this time, the output of AND3 momentarily becomes "H" and is input to the input terminal CP of FF ₂ , which is provided to reverse the rotation direction of the motor, the output of FF ₂ is reversed, and Q becomes "H". ”The next side becomes “L”.

_FF3 next to _FF2 is a flip-flop provided to issue an operation end signal, and the voltage applied to its input terminal CP changes from "L" to "H".
It operates only when . Therefore, when winding of the processing agent coated tape W and film F is completed,
Since the output of FF ₂ changes from "H" to "L", FF ₃ does not operate, but the processing agent coated tape W
When rewinding of film F is completed, FF ₂
Since the output of changes from “L” to “H”,
_FF3 operates and its output Q outputs "H". The output Q of FF ₃ is connected to the input terminal 2 of NOR 1, and when the output Q of FF ₃ becomes "H", the output of NOR 1 becomes "L". Then, since the output of AND1 connected to the output terminal of NOR1 through resistors _R4 and _R5 becomes "L", transistor _TR2 is turned off, and no current flows through motor M. Therefore, motor M stops rotating.

Through the above operations, the processing agent application tape W and the film F are rewound, but in this state, the tension between the processing agent application tape W and the film F causes the film, etc. in Figs. 1 and 2 to be rewound. The hook 512 that fixes the winding shaft 51 may be stopped at the bottom of the main body 11. In this state, it is difficult to insert a hand into the main body, and it is difficult to remove a film or the like from the hook 512. Therefore, the operation end signal is
Even if the output is output from the output Q of the FF ₃ , the output of the Noah 1 connected to this Q is maintained at "H" for a certain period of time, and the motor M is rotated in the winding direction.

A resistor R ₄ and a resistor R ₅ are connected in series to the output terminal of the NOR 1, and a capacitor C ₃ is connected between the resistor R ₄ and the resistor R ₅ . Therefore, even when the output of NOR 1 changes from "H" to "L", the capacitor _C3 is discharged, so that the output of NOR 1 remains "H" for a certain period of time. Since the output of FF ₂ , which is provided to reverse the rotation direction of motor M, is H, AND 2 and NAND 1 become active, transistors TR ₃ and TR ₄ are turned on, and motor M , rotates in the winding direction for the time that the output of Noah 1 maintains "H", and the hook 512
is in an easily accessible position, making it easier to remove the film F, etc.

Next, the operation display circuit 2 will be explained.

In this embodiment, the film F in the photoreceptor processing device is
Divided into three stages: winding, stopping, and rewinding.
A separate light emitting diode LED is emitted for each operation,
Each stage will be displayed in different colors.

Operation start switch for driving motor M
When SW ₄ is turned on, motor drive control circuit 4
The output of FF ₁ becomes "L", and the output of NOR 1 connected to it becomes "H". This "H" voltage is applied to the input terminal 1 of AND2 via resistors R ₄ and R ₅ , and the output of AND2 becomes "H".
At this time, the transistors TR ₃ and TR ₄ are turned on, and the motor M starts winding the film F and the like.
When the output of AND2 becomes "H", the transistor in the operation display circuit 2 connected to this output
TR ₁₀ turns on and light emitting diode LED ₂ emits light.

When the motor M finishes winding the film F, etc., the output of FF ₂ is inverted and becomes "L", this voltage is applied to the input terminal 2 of AND 2, and the output of AND 2 becomes "L". By becoming,
Transistor connected to this output terminal
TR ₁₀ is turned off and light emitting diode LED ₂ stops emitting light.

When motor M finishes winding film F, etc.,
The output of MM ₂ in the motor drive control circuit 4 is inverted,
Since Q outputs an “H” output, the transistor _TR11 connected to this output terminal turns on,
This time, light emitting diode LED ₃ emits light.

When a certain period of time has elapsed during which driving of the motor M is stopped, the output of MM ₂ is reversed, and Q becomes "L" and Q becomes "H". Since the output Q of MM ₂ becomes “L”, the transistor TR ₁₁ in the operation display circuit 2
is turned off and the light emitting diode LED ₃ stops emitting light.

At this time, the output of MM ₂ outputs an "H" output, and this output is applied to the input terminal 2 of AND 4 in the operation display circuit 2.

After motor M stops driving for a predetermined time,
The motor M must rotate in the opposite direction to the winding direction in order to rewind the film F, etc., and the transistors TR ₂ and TR ₅ in the motor drive circuit 6 must be turned on. To turn on the transistor TR ₂ , the transistor in the motor drive control circuit 4 must be turned on.
TR ₆ must be in the on state, so the output of AND1 connected to transistor TR ₆ is "H". Therefore, if the output of AND1 is connected to the input terminal 1 of AND4 in the operation display circuit 2, AND4 becomes active only when the motor M is rewinding the film F or the like. If the output of AND4 is connected to the transistor TR ₁₂ in the operation display circuit 2, the light emitting diode LED ₄ will emit light only during rewinding.

When the motor M finishes rewinding the film F, etc.,
The Q of FF ₃ becomes "H", which is applied to the input terminal 2 of NOR 1 as an operation end signal, and the output of NOR 1 becomes "L". Then, by applying “L” to the input terminal 1 of AND 1 connected to the output terminal of NOR 1, the output of AND 1 becomes “L”, and the input of AND 4 in the operation display circuit 2 “L” is added to terminal 1, and the transistor
TR ₁₂ is turned off. Therefore, light emitting diode
Light emission of LED ₄ is stopped.

At the same time, the operation end signal from FF ₃ is applied to the operation end buzzer circuit 22, and by sounding the buzzer BZ, it is possible to know that the operation of the photoconductor processing device has ended, and the lid 12 is opened. All operations are completed by taking out the film F.

FIG. 6 is a time chart of signals showing the above series of operations.

6. Effects of the Invention As mentioned above, the photoreceptor processing apparatus of the present invention is very useful especially in processing long photoreceptors,
Moreover, since the operation is simple and the operation is processed electrically, the processing operation can always be performed with high reliability.

Since the timer time can be adjusted, processing times such as development can be set with good control, and the processing time can be changed in response to changes in ambient temperature, properties of the photoreceptor, etc. to ensure good processing. I can do it.
Because the device is small and can be powered by both batteries and a household electrical outlet, there is no need to choose a location to process the photoreceptor.

Further, since the winding, stopping, and rewinding operations of the photoreceptor, etc., performed in the photoreceptor processing apparatus are displayed externally, the processing status can be easily grasped. Also, due to the difference in the display, it is possible to easily predict the completion time of photoreceptor processing, which eliminates the need for frustration.
