Description

  The present invention relates to a document processing apparatus, and more particularly to an automatic document processing apparatus.

  As shown in FIG. 1, a conventional automatic document processing apparatus 100 ′ includes a paper input stacker 1 ′, a paper separation module 2 ′, a paper input module 3 ′, a first swing arm sensor 41 ′, and a second swing arm sensor 42 ′. , A document processing module 5 ′, a paper output module 6 ′, and a paper output stacker 7 ′. On the paper input stacker 1 ′, a pressure elastic piece 11 ′ is installed. The paper separation module 2 'is provided with a paper separation roller 21' and a friction piece 22 '. A paper input main driving wheel 31 ′ is installed in the paper input module 3 ′. A swing arm (not shown) and a photoelectric sensor (not shown) are installed in the second swing arm sensor 42 '. The document processing module 5 'can scan, print, and copy.

  This will be described below by taking a paper piece scan as an example. During the operation of the automatic document processing apparatus, a plurality of paper pieces 8 'are set on the paper input stacker 1'. The paper piece 8 'includes a first paper piece 81' and a second paper piece 82 '. The paper separation module 2 ′ applies a force in the traveling direction to the paper piece by using the weight of the paper piece and the pressure paper elastic piece 11 ′ above the paper piece. The paper separation roller 21 ′ uses a frictional force to introduce a paper piece on the paper input stacker 1 ′ into a paper separation area (not shown) where the paper separation roller 21 ′ and the friction piece 22 ′ contact. The paper separation module 2 'separates the paper pieces in the paper separation area, and then introduces the paper pieces into the paper input module 3'. The paper input module 3 ′ introduces a piece of paper to the document processing module 5 ′ at a constant speed and stably. The document processing module 5 'scans the document, and the paper output module 6' outputs a piece of paper onto the paper output stacker 7 '.

  In the conventional technique described above, the linear velocity when the paper input main driving wheel 31 'rotates is V2, the linear velocity when the paper separating roller 21' rotates is V1, and the linear velocity V2 is larger than the linear velocity V1. When the first paper piece 81 'is interlocked by the paper separating roller 21', the speed is V1. When the first paper piece 81 ′ contacts the paper input main driving hole 31 ′ of the paper input module 3 ′ and is interlocked by the paper input main driving hole 31 ′, its speed changes to V2. Thereafter, the first paper piece 81 'advances at the speed of V2 until the paper output module 6' feeds the first paper piece 81 'to the paper output stacker 7' at the speed of V2.

  In this process, when the first paper piece 81 ′ leaves the paper separation roller 21 ′, the second paper piece 82 ′ contacts and moves forward by contacting the paper separation roller 21 ′. At this time, the second paper piece 82 'starts to advance at a speed of V1, and the first paper piece 81' advances at a speed of V2. Since V2> V1, the first paper piece 81 ′ and the second paper piece 82 ′ gradually spread with time to produce a document gap. As the document passes through the second swing arm sensor 42 ', the swing arm is pushed away from its natural position. When the document passes through the second swing arm sensor 42 ', the swing arm of the second swing arm sensor 42' returns to the natural position (initial position). The scanner system installed in the document processing module 5 'generates a signal according to the change in the swing arm position of the second swing arm sensor 42' caused by the document gap, and can know the start of scanning and the accommodation time of each piece of paper. In this way, it is possible to control the time for the image sensor to read an image, obtain image data one by one, and transmit the image data to the user's computer.

  The conventional automatic document processing apparatus 100 'described above uses the speed difference between the paper input main driving wheel 31' and the paper separation roller 21 'to generate a document gap and achieve the purpose of page-dividing the document. However, the difference in speed between the paper input main driving wheel 31 'and the paper separation roller 21' is liable to cause the document to be caught, which may cause damage to the scanned document and image defects. Due to the speed difference, the paper input main driving wheel 31 ′ needs to be interlocked with the paper separation roller 21 ′, and the load of the step motor that interlocks with the paper input main driving wheel 31 ′ is also increased. The present invention has been made in view of the above-described drawbacks of conventional automatic document processing apparatuses.

  The problem to be solved by the present invention is to provide an automatic document processing apparatus which has a good image because it does not cause paper catching, and does not increase the load of the stepping motor linked with the paper feed roller, and also has an image proofreading function. Is to provide.

In order to solve the above problems, the present invention provides the following automatic document processing apparatus.

The speed sensor is installed upstream of the paper separation module, the speed sensor is capable of sensing whether a document is moving, and transmits a control signal to the controller, the controller separating the paper separation roller Control the rotation and stop of the.

  In the present invention, the linear speed of the paper separating roller and the paper input main wheel is similar, the speed sensor senses whether the document is moving, and the control signal is transmitted to the controller. Based on the incoming control signal, the rotation and stop of the paper separating roller can be controlled, and thus the purpose of dividing each page and scanning the image can be achieved. In the scanning process, it is not necessary to separate a piece of paper by causing a speed difference, so that the piece of paper does not get caught, the chance of breakage of the piece of paper and an image defect can be reduced, and the load on the step motor can be reduced. .

FIG. 3 is a schematic structural diagram of a speed sensor in an automatic document processing apparatus according to a second embodiment of the present invention.

  The best mode for carrying out the present invention will be described in detail below with reference to the drawings.

  As shown in FIG. 2, which is a schematic structural diagram of the automatic document processing apparatus 100 according to the first embodiment of the present invention, in the present embodiment, the automatic document processing apparatus 100 is a scanner. The automatic document processing apparatus 100 includes a paper input stacker 1, a paper take-off roller 2, a paper separation module 3, a speed sensor 4, a document processing module 5, a paper input module 6, a paper output module 7, a paper piece sensor 81, and a paper leading end sensor. 82.

  As shown in FIGS. 2 and 3, the paper input stacker 1 includes a paper set board 11, a paper width guide piece (not shown), a first pressure paper elastic piece 12 and a second pressure paper elastic piece 13 installed above the paper set board 11. Is provided. The paper set board 11 has an inclined shape and is fixed on a support base (not shown), and a plurality of paper pieces 9 waiting for scanning can be placed on the paper set board 11 in an overlapping manner. The paper piece 9 includes a first paper piece 91, a second paper piece 92, and a third paper piece 93. The first compressed paper elastic piece 12 and the second compressed paper elastic piece 13 interlock the paper piece 9 and smoothly guide it to the meshing area (Nip Area) installed in the paper separation module 3, and apply a force toward the paper piece 9 in the traveling direction. In addition, the paper piece 9 is thereby transmitted.

  As shown in FIGS. 2 and 5, the paper take-up roller 2 is installed below the paper input stacker 1 and connected to a step motor. The step motor is controlled by a dedicated integrated circuit. A dedicated integrated circuit is installed as a controller and electrically connected to the computer. The paper take-off roller 2 takes out the paper piece 9 overlapping the paper input stacker 1 and transmits it to the paper separation module 3.

  The paper separation module 3 is installed downstream of the paper removal roller 2 and downstream of the paper set board 11. The paper separation module 3 includes a retard wheel 31 and a paper separation roller 32 positioned below the retard wheel 31. A mesh area (Nip Area) between the retard wheel 31 and the paper separation roller 32 is a paper separation area. A plurality of paper pieces are separated in the paper separation area. The retard wheel 31 provides an inhibition torque through a torque component (not shown) to generate an inhibition force necessary for paper separation. The retard wheel 31 may be a stop friction piece. The paper separating roller 32 is connected to a step motor.

  When the paper separating roller 32 rotates counterclockwise, the first paper sheet 91 located on the right side of the retard wheel 31 and the paper separating roller 32 and in contact with the paper separating roller 32 receives the frictional force of the paper separating roller 32. Linked downstream. When the first paper piece 91 is introduced into a paper separation area where the retard wheel 31 and the paper separation roller 32 are in contact with each other, the first paper piece 91 receives an inhibition force opposite to the forward direction applied by the retard wheel 31. However, since the forward frictional force that the paper separating roller 32 applies to the first paper piece 91 is larger than the inhibition frictional force that the retard wheel 31 applies to the first paper piece 91, the first paper piece 91 moves downstream. The other piece of paper is subjected to the obstructive force of the retard wheel 31 in the opposite direction, and the first paper piece 91 rubs against the second paper piece 92 to generate a forward frictional force that interlocks the other paper pieces. In the other piece of paper, since the inhibition force of the retard wheel 31 is larger than the forward frictional force generated by friction between the paper pieces, the first paper piece 91 separates the paper separation module 3 from the other paper pieces. Thus, the data is transmitted to the paper input module 6 through the paper separation area.

  As shown in FIGS. 2 and 6, the speed sensor 4 is located upstream of the paper separation module 3 and is installed below the paper set plate 11. The speed sensor 4 includes a speed sensing module 41 and a signal processing module 42. The speed sensing module 41 includes a light emitting diode 411, a lens 412, an image sensor 413, and a microprocessor 414. The light emitting diode 411 is located on the left side of the lens 412, and the image sensor 413 is located below the lens 412. The light emitting diode 411 is a red light emitting diode, a laser diode, or the like. In this embodiment, the light emitting diode 411 is a red light emitting diode.

  The light emitting diode 411 irradiates the surface of the paper piece 9 in the lowest layer of the sensing area of the speed sensor 4 with red light emitted from the light emitting diode 411. The lens 412 forms an image on a part of the light beam reflected from the surface of the paper piece 9 on the image sensor 413. The image sensor 413 records an image of a series of paper strip surfaces and transmits it to the microprocessor 414. This can also be expressed as “take continuous pictures” on the surface of a piece of paper. Since the surface of the paper piece is a fine rough surface, the image sensor 413 forms an image of a certain kind of texture. The microprocessor 414 performs an analysis process on the series of images captured by the image sensor 413 and analyzes the change in the texture feature point position on the front and back images. A movement direction and a movement distance (defining positions in the x and y directions) on the two-dimensional coordinates are determined and output to the signal processing module 42 and the controller. The controller calculates the moving direction and moving distance of the piece of paper on the two-dimensional coordinates as distortion degree information, calculates the speed and degree of distortion of the piece of paper, and transmits the calculation result of the degree of distortion to the computer.

  The signal processing module 42 compares the movement amount of the paper piece of the lowest layer of the paper piece 9 with the set value in the signal processing module 42, and outputs a control signal to the controller which is a dedicated integrated circuit based on the comparison result. To do. Based on the control signal, the controller determines whether or not the paper piece in the lowest layer of the paper piece 9 is moving. The signal processing module 42 compares the movement amount of the paper piece of the lowest layer of the paper piece 9 with the set value in the signal processing module 42, and outputs a control signal to the controller which is a dedicated integrated circuit based on the comparison result. To do. Based on the control signal, the controller determines whether or not the paper piece in the lowest layer of the paper piece 9 is moving.

  As shown in FIGS. 2 and 6, the document processing module 5 includes a contact-type image sensor (Contact Image Sensor) 51. The document processing module 5 is installed downstream of the paper input module 6 and scans a piece of paper 9 fed by the paper separation module 3 under the control of a dedicated integrated circuit.

  As shown in FIG. 2, the paper input module 6 includes a paper input main driving wheel 61 and a paper input passive wheel 62 positioned above the paper input main driving wheel 61. The paper input main driving wheel 61 is connected to a step motor, and the speed thereof is similar to the linear speed of the paper separating roller 32. The paper input passive wheel 62 is movably installed on the support table. The paper input module 6 is located upstream of the document processing module 5 and downstream of the paper separation module 3. The documents separated through the paper separation module 3 are sequentially transmitted to the document processing module 5 by interlocking with the rotation of the paper input passive wheel 62 by the rotation of the paper input main driving wheel 61.

  The paper output module 7 includes a paper output main driving wheel 71, a paper output passive wheel 72 positioned above the paper output main driving wheel 71, and a paper output stacker 73 positioned downstream of the paper output main driving wheel 71. The paper output module 7 is located downstream of the document processing module 5. The paper output main driving wheel 71 is connected to a step motor. The paper output passive wheel 72 is movably installed on the support table. The paper pieces 9 that have been processed by the document processing module 5 are sequentially sent to the paper output stacker 73 by interlocking with the rotation of the paper output passive wheel 72 by the rotation of the paper output main driving wheel 71. The paper output stacker 73 can place the paper piece 9 after scanning.

  As shown in FIGS. 2 and 4, both the paper piece sensor 81 and the paper leading end sensor 82 include swing arms (not shown). The paper piece sensor 81 is installed below the paper set board 11 and is electrically connected to a controller, which is a dedicated integrated circuit, and senses whether or not the paper piece 9 is on the paper set board 11. When the paper piece 9 is on the paper set plate 11, the swing arm is positioned at the position D by the acting force of the paper piece 9, or the swing arm is returned to the position C by elasticity. The paper leading end sensor 82 is installed between the paper separation module 3 and the paper input module 6. When the leading edge of the paper piece 9 is transmitted, touches the swing arm, and pushes the swing arm, the paper leading end sensor 82 issues a paper piece entry signal to the controller, and the controller controls the document processing module 5 for a predetermined time ( After the paper piece approach signal is received, scanning is started at a certain time). When the end of the paper piece 9 leaves the swing arm, the paper front end sensor 82 sends a signal to the controller that the paper piece has left the swing arm. The controller controls the document processing module 5 and ends the scanning at a predetermined time (a certain time after the signal that the piece of paper has left the swing arm is received).

  As shown in FIGS. 2 and 6, when the user inputs a paper piece 9, the paper piece 9 is positioned on the paper input stacker 1. At this time, the distance between the leading edge of the first paper piece 91 and the swing arm position of the paper leading end sensor 82 is d1. Assuming that the time when the automatic document processing apparatus 100 of the present invention starts to operate is T0, the paper take-off roller 2 starts rotating, and the paper separating roller 32, the paper input main driving wheel 61, and the paper output main driving wheel 71 are all. , Rotation starts at a linear velocity of V1. As the paper take-up roller 2 rotates, the first paper piece 91 starts to move to the paper separation module 3. The paper separating roller 32 utilizes the frictional force generated between the first paper piece 91 and moves the first paper piece 91 downstream, and the remaining paper pieces 9 such as the second paper piece 92 and the third paper piece 93 are retarded. It stops due to the inhibition of the wheel 31. At this time, the speed sensor 4 senses the movement of the first piece of paper 91 and thus transmits a control signal to the controller.

  7 and 9, after d1 / V1 time (this time is assumed to be T1), the leading edge of the first paper piece 91 moves until it contacts the swing arm of the paper leading edge sensor 82. Press the swing arm. Thus, the paper leading end sensor 82 sends the paper piece input signal to the controller which is a dedicated integrated circuit. At this time, the distance between the leading edge of the first paper piece 91 and the scanning position of the document processing module 5 is d2. Thereby, after d2 / V1 time (this time is assumed to be T2), the leading edge of the first paper piece 91 passes through the center scanning position of the document processing module 5. The controller, which is a dedicated integrated circuit, instructs the contact image sensor to start scanning the document at T2, and forwards the image signal to the dedicated integrated circuit.

  As shown in FIGS. 7 and 8, the distance between the sensing zone position of the speed sensor 4 and the center position of the paper separation module 3 is assumed to be L1. The speed sensor 4 senses the speed of the second paper piece 92 when the end edge of the first paper piece 91 leaves the sensing zone position of the speed sensor 4 after being transmitted for a certain period of time. Since the second paper piece 92 is in a state close to rest, the speed detected by the speed sensor 4 decreases from V1 to a speed close to zero. Thereby, the speed sensor 4 transmits a control signal to the controller. If this time is assumed to be T3, then after L3 / L1 time (this time is assumed to be T4) after T3, the end edge of the first paper piece 91 passes through the center position of the paper separation module 3 (see FIG. 10). ) Thus, the first paper piece 91 leaves the paper separation module 3. At this time, the controller controls the paper separating roller 32, pauses for a short time, and then continues to rotate (that is, waits for the first paper piece 91 to leave the paper leading end sensor 82, and the paper separating roller 32 Start rotating again). As a result, the first paper piece 91 and the second paper piece 92 create a document gap, and thus the paper leading end sensor 82 can separate the leading end of the paper piece 9.

  As shown in FIGS. 11 and 12, after the first paper piece 91 is transmitted for a certain period of time, the end of the first paper piece leaves the swing arm of the paper leading end sensor 82. The paper leading end sensor 82 sends a signal to the controller that the end of the paper piece has been separated. Assume this time is T5. Thus, it can be seen that the end of the first paper piece 91 leaves the scanning position of the document processing module 5 after d2 / V1 time (assuming this time is T6). Therefore, the automatic document processing apparatus 100 ends the scanning of the first paper piece 91 in T6 under the control of the controller, and the scanning system sets the image scanned in the time T2 to T6 as the image of the first paper piece 91. Further, the image data is transmitted to a computer by an SDRAM (not shown), and the computer combines the distortion degree information of all the pieces of paper and calibrates the image.

  The first paper piece 91 is sent to the paper output stacker 73 by the paper output main driving wheel 71 to complete one cycle of work. The paper separation module 3 continues to transmit the paper piece 9 to the downstream document processing module 5, thus completing the scanning of a number of paper pieces.

  As shown in FIGS. 13 to 15, the distance between the center scanning position of the document processing module 5 and the meshing center position of the paper output main driving wheel 71 and the paper output passive wheel 72 in the paper output module 7 is E. . When the last piece of paper, that is, the end edge of the third paper piece 93 leaves the paper piece sensor 81, the swing arm of the paper piece sensor 81 returns to the position C by elasticity. That is, it is indicated that the paper input stacker 1 will soon have no paper piece 9. At this time, the paper piece sensor 81 transmits a signal to the controller. Assume this time is T7. The distance of the meshing center position between the paper piece sensor 81 and the paper separation module 3 is L2. When the time of L2 / V1 further elapses after T7, the end edge of the third paper piece 93 passes through the paper separation module 3. At this time, the paper separation roller 32 stops rotating under the control of the controller. After T8 and further after (d1 + d2) / V1 time (this time is assumed to be T9), the automatic document processing apparatus 100 finishes scanning all the documents. After T9, after another E / V1 time (the scanning system usually rotates the motor somewhat more so that the paper strip is completely delivered, so it will take a little more time than E / V1). The three paper pieces 93 are sent to the paper output stacker 73 by the paper output main driving wheel 71 (see FIG. 15), and the dedicated integrated circuit also controls the step motor and stops the operation according to this.

  As shown in FIGS. 2 and 16, the structure of the second embodiment of the automatic document processing apparatus 100 of the present invention is similar to the structure of the first embodiment. The difference between the two is that the principle of the speed sensor 4 ″ of the second embodiment is different from that of the speed sensor 4 of the first embodiment.

  The speed sensor 4 ″ includes a roller 41 ″, a scale turntable 42 ″, a photoelectric sensor, and a signal processing module 45 ″. The roller 41 ″ is installed below the paper input stacker 1 and is movably installed on the support table. The upper surface of the roller 41 ″ is in contact with the surface of the paper piece 9 in the lowest layer of the paper input stacker 1. The scale turntable 42 ″ is a roller. It is fixed to the right end of 41 ″ and rotates according to the rotation of the roller 41 ″. The scale turntable 42 ″ is made of a material that does not transmit light, and has a plurality of light through holes 421 ″ that penetrate both the left and right side surfaces. The light through holes 421 ″ are arranged in an annular shape and arranged at equal intervals.

  The photoelectric sensor includes a light emitting diode 43 ″ and a receiver 44 ″. The light emitting diode 43 ″ is installed on the left side of the scale turntable 42 ″ and is opposed to the light through hole 421 ″. The light emitting diode 43 ″ irradiates the receiver 44 ″ with the red light emitted from the light emitting diode 43 ″. , Placed on the right side of the scale turntable 42 ″, facing the light emitting diode 43 ″ and receiving the light beam from the light emitting diode 43 ″. The paper separating roller 32 rotates and the lowest piece of paper 9 is transmitted downstream. At this time, the roller 41 ″ receives the frictional force of the paper piece 9 and rotates. At this time, the receiver 44 ″ receives the light beam of light and darkness, and thus the receiver 44 ″ generates on (1) and off (0) signals and transmits them to the signal processing module 45 ″.

  The signal processing module 45 ″ performs analysis processing on a series of signals received by the photoelectric sensor receiver 44 ″, and analyzes the on (1) and off (0) signal changes. Judge the movement of the piece of paper. If the on (1) and off (0) signals switch rapidly within a certain time, it indicates that the piece of paper 9 is moving. If the on (1) and off (0) signals maintain the same signal within a certain period of time (mainly 1 or only 0), it means that the piece of paper 9 has not moved. Is shown. Through this determination, the signal processing module 45 ″ outputs the determination result (whether or not the piece of paper is moving), and transmits it as a control signal to the controller, which is a dedicated integrated circuit. The related scan start operation and end operation are completed, and the work process of this embodiment and the work process of the first embodiment are similar and will not be described in detail.

  As described above, the automatic document processing apparatus 100 of the present invention detects whether or not the document is moving by the speed sensors 4 and 4 ″, and transmits a control signal to the controller. 4 ″ controls the rotation and stop of the separation roller based on the control signal transmitted, thereby achieving the purpose of dividing each page and scanning the image. In the scanning process, it is not necessary to separate a piece of paper by causing a speed difference, so that the piece of paper does not get caught, the chance of breakage of the piece of paper and an image defect can be reduced, and the load on the step motor can be reduced. .

  Although the foregoing description has presented the preferred embodiment of the present invention, various increases, various modifications and substitutions may be applied to the optimal embodiment of the present invention, all of which are claimed in the present invention. Does not depart from the principle and spirit of the invention. Those skilled in the art will be able to make many types, structures, installations, ratios, materials, parts, and assembly modifications upon understanding the present invention. For example, the paper take-up roller 2 and the paper separate roller 31 in the above-described embodiment can be replaced with an enlarged paper piece separate roller. The roller can be replaced with an equivalent belt. The function of the paper piece sensor 81 can be substituted by indicating that there is no paper piece 9 in the paper input stacker 1 when the speed sensor 4 senses that there is no light reflection or minute light reflection signal. Further, in a situation where the angle of the paper input stacker 1 (the angle between the stacked paper pieces and the horizontal plane) is large, the force in the traveling direction provided by the compressed paper elastic piece 13 is substituted by the force in the traveling direction provided by the weight of the paper pieces. be able to.

  The scale turntable 42 ″ in the second embodiment can be applied and installed on both sides as a light-absorbing material and a light-reflecting material that cross each other and are arranged at equal intervals, and are light-emitting diodes 43 ″. And the receiver 44 "are installed on the same side of the scale turntable 42". The light beam emitted from the light emitting diode 43 ″ irradiates the scale turntable 42 ″, and when the roller 41 ″ rotates, the receiver 44 ″ receives light beams of different brightness due to the reflection of the scale turntable 42 ″. In this way, on (1) and off (0) signals are generated and transmitted to the signal processing module 45 ", thus realizing the associated control. Accordingly, the examples and all aspects posted herein are merely used to describe the present invention and are not intended to limit the present invention.
