Description

[Detailed description of the invention]

[Industrial Field of Application] - The present invention relates to a control device for a recording device such as a copying machine, and more particularly to a control device for a servo mechanism suitable for controlling the optical system, photosensitive material unit, automatic document feeder, etc. of a recording device. . [Prior Art] In recent years, the development of so-called software servo technology has been remarkable, and there are systems that can perform servo control through software processing. However, in recording devices such as copying machines, it is necessary to Alternatively, in order to obtain a developed image according to an image signal, it is necessary to control the speed of a motor for driving an optical system or a sensitive material at extremely high speed and accuracy. However, in order to deal with this, the computational power of the CPU becomes a problem since all processing is handled by software, and a CPU with high-speed, high-precision computational power is required. Therefore, a digital servo is used, which balances and optimizes the system in consideration of cost, functionality, and division of hardware and software functions. As a control device for such a recording device, for example, the 39th
There is one that uses a servo mechanism as shown in Figure (a). A load 904 such as an optical system or a photosensitive material unit is configured to be driven by a servo motor 903, and the servo motor 903 converts the speed setting data into an analog signal by a target speed setting circuit and converts the speed command voltage E1 into a compensator 901. , the voltage E amplified by the amplification 8902. A rotary encoder 905 is connected to the rotating shaft of the servo motor 903, and the frequency of the encoder 905 is converted into a voltage according to the frequency by an F/V converter (speed detector) 906, and this converted voltage is sent to the comparator circuit 9.
It is designed to be fed back to 02. Now, when the servo motor 903 is stopped, the speed instruction voltage E
When l is given, the feedback voltage is Ef-O, so the control deviation becomes ε""Et Et -Er, which is amplified by the compensator 901 and the amplifier 902 to generate the motor applied voltage E. As the rotation of the servo motor 903 increases, the frequency of the encoder 905 increases, and the feedback voltage Et output from the F/V converter 906 becomes thicker (as a result, the control deviation ε''=E
As t-Et gradually decreases, motor applied voltage E0
also decreases, and the control deviation ε becomes the E required to produce the target rotation.
, it rotates stably when balanced with . Also, when the servo motor 903 is rotating in a steady state, the load 903
When the rotation of the motor decreases due to the fluctuation of 04, the feedback voltage E decreases, and as the control deviation ε increases, the motor applied voltage E also increases to maintain the rotation speed. In the above control device, as shown in (a) of FIG. 39(b), the speed instruction voltage E! When the motor is a positive voltage, the motor applied voltage E0 is also positive, and the remote rotates in the positive direction. When the speed instruction voltage E1 is a negative voltage, the motor applied voltage E is also negative. When the circuit is configured so that the motor rotates in the reverse direction, If this circuit is ideal, the motor will stop when the motor applied voltage E=0 when the speed instruction voltage El is 0. However, in actual circuits, there are offset voltages and drifts.
November 30, 2015, published by CQ Publishing Co., Ltd., page 46)
' shows an F/V converter circuit, and describes circuit errors due to offset voltage and drift. Therefore, when the speed instruction voltage Ei is 0, the motor applied voltage E, -
It will not become 0 and the motor will rotate. Therefore,
ENA of amplifier 902 only when you want to rotate the motor.
The motor is controlled on/off by sending a signal to the BLE terminal. [Problem to be Solved by the Invention] However, in the above servo mechanism, when a positive voltage is applied to the speed instruction voltage E+ and the ENABLE terminal of the amplifier 902 is turned on in order to rotate the servo motor 903 in the forward direction, the circuit gain is If a large negative circuit offset exists, the motor applied voltage E0 may become a negative voltage and the servo motor 903 begins to rotate in reverse. Here, the characteristics of the conventional F/V converter 906 are as shown in (b) of FIG. becomes. Therefore, while the servo motor 903 is rotating in the reverse direction, the control deviation ε-Er Et occurs in the same way as when it is rotating in the forward direction, and the negative voltage due to the offset voltage increases, further accelerating toward the reverse side, and eventually There is a problem in that the feed variation voltage E is larger than the speed instruction voltage El, causing the servo motor 903 to run out of control, leading to, for example, damage to the optical system (lamp, mirror, etc.) of the recording apparatus. To solve this, from a sine wave output encoder to
° Extract the phase-shifted sine waves of A and B phases and create a special I
There is a method of obtaining forward and reverse voltages by full-wave smoothing with C, but since the output amplitudes of A phase and B phase are different, the feedback voltage fluctuates, and as a result, the rotation of the servo motor fluctuates. It has the problem of being stored away. The object of the present invention is to solve the above-mentioned problems, and to reduce the burden on the software and obtain a speed signal that takes into account forward and reverse rotation of the servo motor with a simple hardware configuration, thereby providing a recording device with excellent stability and high-speed response. The purpose is to provide a control device for. (Means for Solving the Problems) For this purpose, as shown in FIG.
, an encoder 157 that converts the rotation speed of the servo motor into two-phase pulse signals with different phases, and an F/V converter 7 that converts the frequency of the output signal of the encoder into a voltage.
30, and a pulse generating means 740 that outputs a predetermined pulse signal based on the output signal of the encoder,
The F/V converter 730 is connected to the pulse generating means 74.
A positive/negative pulse generating means 741 generates positive/negative pulses from a pulse signal of 0; a positive/reverse detecting means 746 detects the forward/reverse rotation of the servo motor 114 from the pulse signal of the encoder; It is characterized by comprising a synthesizing means 747 for selectively outputting the positive and negative pulses of the positive and negative pulse generating means 741, and an integrating means 749 for converting the frequency of the output of the synthesizing means into a voltage. That is, the double frequency of the encoder is input to the pulse generation cutoff, which issues a trigger at the rising edge of the signal to output a pulse signal of a constant width, and the positive and negative pulse generation means 741 generates a positive pulse signal τ and a negative pulse signal. i is generated and sent to the synthesis means 747. On the other hand, the A-phase and B-phase signals of the encoder are input to the forward/reverse detection means 746, where the level of the other signal is checked at the rising edge of one signal, and the forward/reverse signal CW/
0 synthesis means 747 that generates CCW and sends it to synthesis means 747
In the integrating means 749, a positive pulse voltage is output when the forward rotation signal CW is at a high level, and a negative pulse voltage is output when the reverse rotation signal CCW is at a high level.
The frequency is converted into a voltage at the step, and a voltage signal including the characteristics shown in FIG. 1(b), that is, forward and reverse, is output. Note that instead of inputting the double frequency to the pulse generating means 740, an A-phase or B-phase signal may be input.

), the X1Y portions of A phase and B phase are carriage
This is caused by reversal of the position, deviation from the home position, etc.
Ru. Therefore, the servo motor 903 shown in FIG.
When trying to rotate, a positive voltage is applied to the speed instruction voltage Ei.
When the circuit offset causes the motor applied voltage E to become negative.
If the servo motor 903 reverses due to voltage, the F/V controller
Since the inverter outputs a negative voltage, the control deviation ε=Et
Et is corrected by increasing in the positive direction, and the motor applied voltage E
0 will eventually become a positive voltage and will rotate in the normal direction. The result
As a result, it is possible to prevent the servo motor from running out of control as in the past.
For example, damage to the optical system carriage (mirror
, lamp cracks, etc.) and motor burnout. Note that the above embodiment is suitable for the servo mode of the optical system.
