The printing device 10 also includes a deformation output of a sensor die paper 14 during paper feeding, a corresponding one and a paper restraint 34 (paper used to enter the sensing area of the sensor module 3 2 on the paper 14). Buckling. The third is a functional block diagram of the printing device 10. The printing control unit 36 is electrically connected to the sensing module 32 and the sensing signal output by the horse sensing module 32. The paper i 4 can be By controlling the action of the motor 30, the control unit 36 pack is used to amplify the paper detected by the sensor module 32. A type of td digital converter (anal0g, t0_digital) is used to convert the amplifier 38 The output analog signal conversion device further includes a presentation unit 42 electrically connected to the state where the paper 14 is detected by the presentation sensing module 32.

Description of invention (5) 1 4 Whether the paper feed is normal, if the normal paper is completely fed out, if it is abnormal, continue to feed Paper feed action until step 106: The control unit 36 executes step 106 on the control unit 30; 30 receives an interruption signal sent by the control unit 36/2, and the paper feed action by the motor mechanism 24, ^: off After the signal, the paper feed is stopped. Step 108: End the paper feed action. And the paper feed continues with the paper feed roller and then the paper is read as shown in Figure 5. Because the paper reaches 30, the roller 28 and the moment of paper feed fall immediately. The deformation of the sensing deformation emits a sensing signal and the measuring instrument is assembled, etc. However, the limitation is within, so the force can be described in detail from Ma 28, and take 14 and the roller. The roller paper 14 will cause the paper module 32 to be changed, and the signal is sensed until the paper is known, and the paper 14 is fed to make the paper use the paper. The above steps are printed, and the motor 30 rotates the paper roller 2 6 and the static friction band of the paper feed surface. 14 After the paper feed roller 2 8 in the sensing area, the paper 2 8 at this time, the static friction between the front and back of the paper 丨 4 is purely buckled and deformed. Therefore, the sensing module 32 can be used as a reverse paper 14 and can receive In case of change of condition, when the detector can be interrupted and enter the sensing area, the amount of change of the paper 14 is between the restraint 34 and the paper feed of the paper device 10 and the paper take-up roller 2 8 is used to move the paper 1 4 Schematic diagram of forward deformation Zhang 1 4 The power is the end of the movement is to move forward, the standard test module of the paper buckling deformation 3 2 Measurement of the shooting sensor 'Paper 1 4 The reflection can also be reflected by one or reflective 1.

Description of the invention (6) ~ _ When a sensing area is restrained, the bending and deformation of the paper 14 is restrained, and the paper restraint y4 is 5mm away from the sensing module 32, that is, the paper ^ The deformation amount of 14 $ is limited to 5mm, and the distance between the paper restraint 34 and the sensing module 32 can be determined by the designer's own decision according to the effective sensing range of the sensing module 32. The paper can be freely fixed at the fixed end, and the paper supporting frame 16 can be fixed to move 14, the shape of the paper roller end, and the end of the paper feed roller is a sufficient basis for fluctuation. 1 6 becomes paper 1 4 at one end of the paper. After the completion, it is in the end state of 2 6 and the fixed end wheel 28 in the paper is synchronized with the fixed end. The buckling deformation 1 4 starts to move the free end to facilitate the paper feed bracket second feeding. The paper moves forward because it has not been sent for 1 to 4 times. This makes it even more useful, and when providing the movement, it is necessary to make the paper, that is, the paper does not need to be able to fluctuate, and then support and fix it. While the paper feeds through the paper feed support, one of the fixed paper rollers 2 of the frame 16 is fixed to the paper 1 4 so that the paper 1 1 is a paper 1 4 and the forward movement sensor module 3 2 emits 14 adjacent sheets 1 4 Deformation, the paper has not been set in progress, so it can be regarded as an automatic process. The output is sensed when the paper is pressurized and the paper 1 4 appears to be slippery. The signal from the end can be seen in Figure 6, which is shown in Figure 6. When the paper 14 is normally fed, the motor 30 and the sense 32 are signal waveforms. As shown in the figure, if the paper is "pulled for normal paper feeding = every time the motor 30 receives a driving signal, the paper! 4 will go forward, forward-a short distance, and the moment the paper 14 advances will become ^ Fang buckling deformation 'so the sensing module 32' will sense the g-deformation of the paper " 1220883 5. The description of the invention is changed and a corresponding driving signal and sensing response signal of 30 are generated After the time interval has elapsed, the sensor module 3 2 detects that it was born, so it is the paper. Figure 7 shows the paper when the paper 14 is jammed. When paper 1 4 sends the drive signal, it means that That is to say, the paper 14 cannot be advanced, and the paper 14 is buckled and deformed. The deformation of the sheet 14 is changed without sensing the paper 36 detected by the module 32. The amplifier 38 is first replaced by the amplifier 40 and the amplifier 38 is output. The control unit 36 can determine whether the sheets of paper 14 are feeding normally or responding to the response signal waveform, and the horse module 3 2 彳 detects that the deformation of the paper 1 4 is not large, and the motor 3 0 The driving signal generated by the paper 1 4 The response signal generated by the deformation should be 1 4 the normal paper feeding condition Please refer to Figure 7. Signal waveforms of up to 30 and sensing module 32. When paper jams occur, the motor 30 will continue to indicate that the motor 30 is still rotating, but no paper will be produced due to the paper jam. 1 4 caused by the moment of advance, so the sensor module 32 cannot sense that the paper will produce a corresponding response signal waveform. And the buckling deformation of Zhang 1 4 will be transmitted to the control unit to make the fluctuation change, and then go through the analog digital The analog signal of the rotation is converted into a digital signal, and the control signal and the above-mentioned judgment methods are used to determine the status of the paper jam. If the paper 14 is in the normal paper feeding state, continue the paper feeding operation until the paper 14 is completely Send out and leave the paper feed roller 2 8; and if the paper 14 is in a paper-like state, the control unit 36 will send an interruption to the motor. 3 〇 Send an interrupt $ ^ 乂 氤 Motor 30 received by the control unit 36 After the interruption signal, the paper feed action performed by g on the paper feeding mechanism 24 is to end the paper feed movement. At this time, the control unit 36 will also send a signal to the presentation unit 4 2 to display the state of the paper. , Its display method can be light or sound Sound and other methods?

Description of the invention (8) ____ Wake up the user to handle the abnormal paper feed as soon as possible, due to the measured percentage from the sensor module 32 and the control unit 36 movement behavior, so you can Therefore, the noise generated by the step of adjusting the motor, that is, controlling the .1 to reduce the motor 3 0 due to the missing sensor signal, to judge the paper g. -Feeding state of feedback This is the principle of a closed loop feedback control = machine and motor 30 behavior, sheet 14 feeding state. To change the printing work and control the paper, and the way of sensing, for example, a sense includes a set on 4 8, the deformation of the moving rod strain gauge material is caused by the voltage of the spring 32 from the paper to the module 32. The principle of action can also make use of, for example, sensing the deformation of the paper 14. Please refer to Fig. 8. The schematic drive link 46 for sensing the deformation of the paper 14 is detected by the test module 44, and one end thereof is used to contact the paper drive link 46 ', and a deformation sensing is used to detect the paper due to the paper 14. The amount of deformation of the spring 4 8 on the paper process 46, and the strain gauge, tensioner, and contact sensor to sense the deformation of the mechanical parts. The sensor 50 is a strain gauge, and because of the surface of the transmission 1 4 Therefore, the transmission link 46 will transmit 48 to the strain gauge, so the voltage change value of different magnitudes that can be generated by the strain deformation can be output to a conversion circuit 52, and the converted voltage value is converted into the corresponding paper shape strain gauge. Sensing, Figure 8 is another picture. The implementation of the deformation of the sensing module is a set of 4 4 can be 14, a spring 48, spring .50, the deformation in the installation and the sensor is a 50-type probe, or.

Description of the invention (9) -----— The deformation is transferred to the control unit 3 β, which is the paper feed state of other printing media. In the second description f, paper 14 or printing process And motor 30 behavior. Compared with the conventional printing device, the feedback signal is controlled. Compared with the conventional printing device, the Taigongri group is 3⑽, > 丨 ¥ 1 wβ The feature of this month is that it can be detected by the sensor module 泸 ϊ ϊ ί Γ ϊ ί Deformation in the process corresponds to the corresponding sensing signal = state: adjust the motion behavior of the motor 30, so that the ΐΐίΐ 2 motor 30 is out of step and the noise is generated, that is, the control of the early 36 will be due to the sensing The sensing signal sent from the module 32 is used to judge the paper feed status of the printing sheet or other printing media, and then output a feedback signal to control the printing process and the behavior of the motor. This is based on The concept of a closed loop feedback control to change the printing work and control the state of paper feeding. And the invention's creation can be applied to systems with paper feed mechanisms such as printers, facsimiles, and multifunction printers (MFPs) that output images. Therefore, the present invention can automatically detect the behavior of the paper 14 to adjust the condition of the paper feeding mechanism 24, and can take real-time processing to improve the shortcomings of noise, and this real-time detection, instant feedback, instant response, and instant processing The characteristics can also improve the efficiency and value of the product. The above description is only a preferred embodiment of the present invention. Any equal changes and modifications made in accordance with the scope of the patent application of the present invention shall fall within the scope of the invention patent.
