Description

  The present invention relates to an automatic document feeder and an image forming apparatus.

  A paper feeder (ADF) described in Patent Document 1 includes a document stacking tray and a pickup roller. For example, a document stack in which a plurality of documents are overlapped can be placed on the document stacking tray. For example, when a document bundle is placed on the document stacking tray, the pickup roller moves from the upper limit position to the lowered position. The pickup roller rotates at the lowered position, and sequentially supplies the uppermost document in the document bundle to the downstream side of the conveyance path. As the document is supplied to the transport path, the pickup roller sequentially descends so as to correspond to the height of the document bundle. The pickup roller moves to the upper limit position after finishing the document feeding operation.

  For example, in a stop mode (sleep mode) such as a power saving state, the pickup roller is lowered from the upper limit position by its own weight. The pickup roller also moves to the upper limit position when transitioning from the stop mode to the standby mode (normal mode). In the paper feeding device described in Patent Document 1, the pickup roller ascending speed after finishing the paper feeding operation is set slower than the pickup roller ascent speed when the stop mode is changed to the standby mode.

  The control unit 9 includes, for example, a processor and a storage unit. The processor is, for example, a CPU (Central Processing Unit). The storage unit includes, for example, a semiconductor memory and an HDD (Hard Disk Drive). Based on the computer program stored in the storage unit, the processor controls the paper feed unit 3, the image forming unit 4, the fixing unit 5, the document reading unit 7, the operation panel 8, and the automatic document feeder 10. Control.

  Next, the configuration of the document reading unit 7 and the automatic document feeder 10 will be further described with reference to FIG. FIG. 2 is a diagram illustrating the configuration of the document reading unit 7 and the automatic document feeder 10.

  The mounting table 71 of the document reading unit 7 includes a first contact glass 71a, a second contact glass 71b, and a partition plate 71c. The first contact glass 71a and the second contact glass 71b are made of transparent plate-like glass. The partition plate 71c is disposed between the first contact glass 71a and the second contact glass 71b. The first contact glass 71a and the second contact glass 71b may be integrally formed. In this case, one contact glass is divided into a first contact glass 71a and a second contact glass 71b by a partition plate 71c.

  The document reading unit 7 further includes a first reading unit 72. The first reading unit 72 is disposed below the mounting table 71. The first reading unit 72 reads an image on the surface of the document R passing over the first contact glass 71a and generates image data. The document R conveyed by the automatic document feeder 10 passes over the first contact glass 71a. Further, the first reading unit 72 reads an image of a document placed on the second contact glass 71b and generates image data. The first reading unit 72 outputs the image data to the control unit 9.

The CIS unit includes an LED (Light Emitting Diode), an imaging lens, and an image sensor. The carriage supports the CIS unit. The guide part 72b extends in the sub-scanning direction. The guide part 72b supports the carriage so as to be movable in the sub-scanning direction.

  In addition to the document table 11, the automatic document feeder 10 further includes a second reading unit 73, a pickup roller 12, a white reference roller 14, a document discharge tray 16, and a plurality of conveyance roller pairs.

  The second reading unit 73 reads the image on the back side of the document R conveyed along the conveyance path in the automatic document feeder 10 and generates image data. The second reading unit 73 outputs the image data to the control unit 9. The second reading unit 73 is, for example, a CIS unit.

  The document table 11 of the automatic document feeder 10 includes a tray main body 11a and an elevating unit 11b. A document bundle R1 including at least one sheet-shaped document R is placed on the tray main body 11a and the lift 11b. The raising / lowering part 11b moves along an up-down direction. The elevating unit 11 b rises when the document R is placed on the document table 11. As a result, the end on the leading end side of the document R rises and comes into contact with the pickup roller 12.

  The pickup roller 12 is disposed above the document table 11. Specifically, it is disposed above the elevating part 11b of the document table 11. As the pickup roller 12 rotates in contact with the upper surface of the document bundle R, the document R positioned at the uppermost stage of the document bundle R1 is sent to the downstream side of the transport path. Specifically, the pickup roller 12 sends out one original R from the original bundle R1, and after the preset time has elapsed, sends out the next original R from the original bundle R1. The pickup roller 12 is fixed concentrically with a support shaft that supports the pickup roller 12. The pickup roller 12 rotates together with the support shaft by power supplied from a rotational power transmission unit (not shown). The rotational power transmission unit includes, for example, a gear and a motor.

  The pickup roller 12 is movable along the vertical direction. Specifically, the pickup roller 12 is movable in the vertical direction between the lower limit position P1 and the upper limit position P2. The pickup roller 12 contacts the document table 11 at the lower limit position P1. The pickup roller 12 does not contact the document bundle R1 having the maximum stacking height placed on the document table at the upper limit position P2. Note that the pickup roller 12 moves along the vertical direction together with the support shaft by power supplied from a mobile power transmission unit (not shown). The moving power transmission unit includes, for example, a gear, an arm unit, and a motor.

  The pickup roller 12 moves along the vertical direction at a first speed or a second speed that is slower than the first speed. The noise generated due to the pickup roller 12 rising at the second speed is smaller than the noise generated due to the pickup roller 12 rising at the first speed. The first speed is, for example, a speed that is two to eight times the second speed. Note that the noise generated due to the rise of the pickup roller 12 includes, for example, driving sound of the mobile power transmission unit. Further, the noise generated due to the rise of the pickup roller 12 includes a contact sound between the pickup roller 12 and a restricting portion that restricts the rising pickup roller 12 to the upper limit position. The restricting portion is, for example, a cover member arranged to cover the pickup roller 12.

  The plurality of conveyance roller pairs of the automatic document feeder 10 conveys the document R sent by the pickup roller 12 along the conveyance path. The white reference roller 14 faces the second reading unit 73 with the document transport path interposed therebetween. The white reference roller 14 transports the document R along the transport path. The white reference roller 14 is used for white reference adjustment of the second reading unit 73. A document R transported along the transport path is placed on the document discharge tray 16.

  Next, the control unit 9 will be further described with reference to FIGS. FIG. 3 is a block diagram schematically showing the image forming apparatus 1. As shown in FIG. 3, an external input device T is connected to the image forming apparatus 1 of the present embodiment. The external input device T inputs an operation signal and image data to the control unit 9. The external input device T is, for example, a personal computer or a facsimile line.

  The control unit 9 changes the mode of the image forming apparatus 1 to one of an operation mode, a standby mode, and a stop mode. The control unit 9 controls each of the sheet feeding unit 3, the image forming unit 4, the fixing unit 5, the document reading unit 7, the operation panel 8, and the automatic document feeder 10 in either the operation mode, the standby mode, or the stop mode. You may make transition to each mode.

  The operation mode includes, for example, a state in which the image forming apparatus 1 performs a copy operation or a scan operation. In the stop mode, the power supplied to each part of the image forming apparatus 1 is reduced compared to the standby mode. The stop mode includes a state in which only the minimum necessary power is supplied to the paper feeding unit 3, the image forming unit 4, the fixing unit 5, the document reading unit 7, the operation panel 8, and the automatic document feeder 10.

  For example, the control unit 9 changes the image forming apparatus 1 from the stop mode to the standby mode based on an operation signal input from the operation panel 8, the document detection unit 11c, or the external input device T. The control unit 9 performs an operation process such as an image forming process or an image data generating process based on an operation signal input from the operation panel 8 or the external input device T. When performing the operation process, the control unit 9 causes the image forming apparatus 1 to transition from the standby mode to the operation mode.

  In the image data generation process, for example, the control unit 9 controls the automatic document feeder 10 to convey the document R, and controls the document reading unit 7 to read the document R and generate image data. Further, the control unit 9 controls the paper feeding unit 3, the image forming unit 4, and the fixing unit 5 so as to form an image on the paper S based on the image data in the image forming process.

  For example, after finishing the operation process, the control unit 9 changes the image forming apparatus 1 from the operation mode to the standby mode. Further, in the standby mode, the control unit 9 causes the image forming apparatus 1 to transition from the standby mode to the stop mode when no new operation signal is input. Specifically, the control unit 9 shifts the image forming apparatus 1 from the standby mode to the stop mode when a preset time has elapsed without receiving a new operation signal in the standby mode. Note that the control unit 9 may cause the image forming apparatus 1 to transition from the standby mode to the stop mode based on the operation signal input from the operation panel 8. The stop mode of the image forming apparatus 1 is typically a power saving mode.

  The control unit 9 measures the number of times the automatic document feeder 10 has sent out the document bundle R1. In the present embodiment, the control unit 9 measures the number of transmissions per unit time between the stop mode and the stop mode. The period between the stop mode and the stop mode is a period from when the image forming apparatus 1 transits from the stop mode to the standby mode and transits to the next stop mode. The control unit 9 sequentially stores the measured number of transmissions in the storage unit. Note that the storage unit only needs to be nonvolatile. For example, an EEPROM (Electronically Erasable and Programmable Read Only Memory) may be employed as the storage unit instead of the HDD.

  The control unit 9 calculates the average number of times of document bundle R1 based on the number of times of transmission stored in the storage unit. The control unit 9 stores the calculated average number of transmissions in the storage unit. The average number of transmissions is calculated and updated every time the image forming apparatus 1 transitions to the stop mode, for example.

  The controller 9 determines whether or not an operation signal is input from the external input device T when the image forming apparatus 1 is shifted from the stop mode to the standby mode based on the operation signal. In the present embodiment, when it is determined that the operation signal is input from the external input device T, the control unit 9 compares the average number of transmissions with a threshold value. The threshold is preset by the user. The threshold value may be a default value stored in advance by the storage unit.

  The control unit 9 compares the average number of transmissions with a threshold and determines whether or not the average number of transmissions is equal to or less than the threshold. The control unit 9 controls the automatic document feeder 10 so that the pickup roller 12 rises at the second speed when the average number of times of delivery is not less than the threshold value. As a result, it is possible to reduce the noise generated due to the pickup roller 12 rising when the stop mode is changed to the standby mode. Further, wear of the pickup roller 12 due to the rise of the pickup roller 12 can be reduced.

  Further, the control unit 9 controls the automatic document feeder 10 so that the pickup roller 12 does not move when the average number of times of delivery is equal to or less than the threshold value. As a result, the pickup roller 12 does not rise when the stop mode is changed to the standby mode based on the operation signal input from the external input device T. Therefore, it is possible to prevent noise generated due to the rise of the pickup roller 12. Further, wear of the pickup roller 12 due to the rise of the pickup roller 12 can be prevented. In the present embodiment, the control unit 9 performs control so that the pickup roller 12 does not move only when the average number of times of delivery is equal to or less than the threshold. For example, the printing function of the image forming apparatus 1 is controlled using the external input device T. This is useful for a user who uses the document reading function of the image forming apparatus 1 less frequently.

  When the control unit 9 determines that the operation signal is not input from the external input device T, in other words, when the operation signal is input from the operation panel 8 or the document detection unit 11c, the pickup roller 12 is moved to the first position. The automatic document feeder 10 is controlled to increase at the speed or the second speed. Whether the pickup roller 12 is raised at the first speed or whether the pickup roller 12 is raised at the second speed can be preset by the user, for example.

  For example, the user sets the rising speed of the pickup roller 12 to one of high speed and low speed via the operation panel 8. Therefore, when the user desires a low speed, the pickup roller 12 is raised at the second speed when the stop mode is changed to the standby mode, and noise generated due to the rise of the pickup roller 12 is reduced. Can do. When the user desires a high speed, the pickup roller 12 is raised at the first speed, and the transition from the stop mode to the standby mode can be completed quickly.

  Next, with reference to FIG. 4, the raising operation process of the pick-up roller 12 by the control part 9 is demonstrated. FIG. 4 is a flowchart showing the lifting operation processing of the pickup roller 12 by the control unit 9. 4 is started when an operation signal is input to the control unit 9 when the image forming apparatus 1 is in the stop mode.

  When an operation signal is input in step S10, the controller 9 determines whether or not the operation signal is input from the external input device T in step S20. When it is determined that the operation signal is not input from the external input device T (No in Step S20), the control unit 9 determines whether or not the low speed is set in Step S30. When the low speed is not set (No in Step S30), the control unit 9 controls the automatic document feeder 10 so that the pickup roller 12 is raised at the first speed in Step S40, and performs the ascending operation process. finish.

  When the low speed is set (Yes in step S30), the control unit 9 controls the automatic document feeder 10 so that the pickup roller 12 rises at the second speed in step S50, and performs the ascending operation process. finish.

  When it is determined that the operation signal is input from the external input device T (Yes in Step S20), the control unit 9 determines whether or not the average number of transmissions is equal to or less than the threshold value in Step S60.

  When it is determined that the average number of times of delivery is not less than the threshold value (No in Step S60), the control unit 9 controls the automatic document feeder 10 so that the pickup roller 12 is raised at the second speed in Step S50. Then, the ascending operation process is terminated. If the controller 9 determines that the average number of times of delivery is equal to or less than the threshold value (Yes in step S60), the controller 9 controls the automatic document feeder 10 so that the pickup roller 12 does not rise in step S70. The operation process is terminated.

  The image forming apparatus 1 and the automatic document feeder 10 according to the embodiment of the present invention have been described above with reference to FIGS. However, the present invention is not limited to the above-described embodiment, and can be implemented in various modes without departing from the gist thereof.

  For example, in the embodiment of the present invention, the image forming apparatus 1 includes the automatic document feeder 10, but the present invention is not limited to this. The present invention can also be applied to a scanner in which the automatic document feeder 10, the document reading unit 7, and the control unit 9 are integrally configured.

  In order to facilitate understanding, the drawings schematically show each component mainly, and the thickness, length, etc. of each component shown in the drawings are different from the actual for convenience of drawing. . Moreover, the shape of each component shown by said embodiment is an example, Comprising: It does not specifically limit, A various change is possible in the range which does not deviate substantially from the effect of this invention.
