  Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 2 is a schematic view showing an example of a recording apparatus with a scanner function according to the present invention. 2 executes a program code supplied from a storage area such as a ROM indicated by 202 and a RAM indicated by 203 by a CPU indicated by 201, or records and stores data. Further, it has a UI unit for accepting a user operation indicated by 204, and it is also possible to execute an operation by the recording apparatus alone, such as a copy operation. 205 is an I / F unit that communicates with other devices such as PCs, digital cameras, and fax machines, and uses the recording device from other devices using various communication means such as USB, LAN, infrared, and telephone lines. It is used when doing. In the present invention, the UI unit 204 or the I / F 205 is not an essential item, and the operation of the recording apparatus may be executed by either one or other means. A driver circuit 206 controls the operation of the scanner unit for reading an image, and controls the reading sensor 207 and the driving system 208 of the reading unit to realize an image reading operation. Reference numeral 209 denotes a driver circuit for controlling the operation of the recording unit, and realizes the recording operation by controlling the recording head 210 and various motors 211, 212, and 213 used for scanning, feeding, and conveying the recording head. . Note that some or all of the driver circuits 206 and 209 may be configured by software instead of an electronic circuit, and the 206 or 209 may include a CPU, a ROM, a RAM, and the like. Alternatively, control may be performed by using the CPU 201, the ROM 202, and the RAM 203.

It may be configured as follows.

  FIG. 1 is a block diagram showing a main part configuration relating to operation control of a recording apparatus according to the present invention.

  When the recording apparatus receives an operation instruction from the UI unit 204 or the I / F unit 205 described in FIG. 2, the image reading unit determines the resolution, scan speed, color / monochrome, etc. Determine settings related to reading operations. When the reading setting is determined in 101, the setting is supplied to the reading means 102, and an image reading operation is executed. On the other hand, after the operation instruction is given, the recording unit determines the setting relating to the recording operation such as resolution, quantization number, and color setting in the recording setting determination unit 103. When the recording setting is determined by the recording setting determining means 103, the recording operation is executed according to the determined setting content. The recording operation is first performed from the supply operation of the recording medium. As will be described later, vibration may occur when the recording medium is supplied. In the present invention, the occurrence of vibration is suppressed by controlling the recording medium supply operation. When the recording setting is determined, the supply operation determination unit 104 acquires operation setting information such as the operation status of the reading unit 102 and the reading resolution. The supply operation determination unit 104 determines the operation of the recording medium supply unit according to the acquired operation status and setting contents of the reading unit. Then, the recording medium supply unit 105 executes the recording medium supply operation in accordance with the determined supply operation. When the recording medium is supplied into the recording apparatus, the recording unit 106 carries the recording medium and performs the recording operation. When all the recording operations are completed, the recording medium discharge unit 107 discharges the recording medium.

  Next, generation and suppression of vibration during the supply of the recording medium will be described with reference to FIGS. FIG. 3 shows an example of a recording apparatus having a reading function to which the present invention is applied. Reference numeral 301 denotes a recording unit in the recording apparatus. A recording medium supply unit 302 that holds the recording medium and supplies the recording medium at the start of the recording operation is attached to the recording unit 301. A discharge unit 303 is attached for discharging and holding the recording medium after the recording operation is completed. Further, the recording apparatus is equipped with a reading unit 304 for reading image information as electronic data. For example, when a copying operation is performed using this apparatus, the document information read by the reading unit 304 is recorded in the recording unit. In 301, recording is performed on a recording medium.

  4 and 5 are diagrams for explaining the recording medium supply unit 302 in FIG. 3 in detail. FIG. 4 shows an example of the recording medium supply unit before the recording operation. Reference numeral 401 denotes a recording medium, which is set in a holding unit 402 for holding the recording medium. Reference numeral 403 denotes a supply roller for supplying the recording medium into the recording apparatus, and is in a state separated from the recording medium in the state of FIG. Reference numeral 404 denotes a pressure plate for bringing the recording medium into contact with the supply roller 403 at the start of the recording operation. When the recording operation is started and the recording medium is supplied, the recording medium supply unit 302 changes from the state of FIG. 4 to the state of FIG. In the state of FIG. 5, in order to bring the recording medium 401 into contact with the supply roller 403, the pressure plate 404 jumps up until it collides with the supply roller 403, and at the same time, the supply roller 403 rotates in a direction to draw the recording medium 401 into the recording apparatus. Through the above operation, the recording medium is supplied into the recording apparatus and the recording operation can be started.

  During the above-described recording medium supply operation, vibration occurs when the pressure plate 404 brings the recording medium 401 into contact with the supply roller 403. In particular, when the recording medium is not held on the recording medium holding unit 402 or when the supply operation fails, the re-execution of the recording medium supply operation may be repeated several times. When re-execution occurs, the pressure plate 404 and the supply roller 403 repeatedly collide, and a larger vibration is generated.

  An object of the present invention is to suppress the vibration generated during the above-described supply operation from affecting the operation of the reading unit 304. More specifically, when the vibration needs to be suppressed, the generated pressure is reduced by changing the operation speed when the pressure plate 404 brings the recording medium 401 into contact with the supply roller 403 to reduce the vibration. Control.

  FIG. 6 is a flowchart showing the flow of the recording operation in the first embodiment of the present invention. When the operation is started, the content of the recording medium supply operation is determined at 601. When the supply operation content is determined, the recording medium supply operation is executed in 602, and the recording medium is supplied into the recording apparatus. When the recording medium is supplied into the recording apparatus, the recording operation is started. For example, in an inkjet printer, the recording operation is performed by ejecting ink while scanning a print head having several tens to several hundreds of ink ejection nozzles in the sub-scanning direction in the main scanning direction orthogonal to the conveyance direction of the recording medium. The band area is recorded (603). When one scan of the print head is completed, the print medium is transported a predetermined amount in the transport direction (604) and then the print head is scanned again until the print is completed. Realized. In the case of an electrophotographic system, a latent image due to static electricity is formed on a transfer roller and toner is attached, and then recording is performed while the transfer roller is pressed against a recording medium to transfer the toner. In this case, the recording operation 603 and the recording medium conveyance 604 are performed simultaneously. If it is determined that the recording operation is completed (605) after the recording operation is started, a recording medium ejection operation (606) is executed.

  The contents of the supply operation determination 601 will be described in detail with reference to FIG. When the supply operation determination is performed, first, information 701 is acquired to determine whether or not the reading operation is being performed or the setting content of the reading operation. Then, based on the information acquired in 701, a determination 702 is made as to whether or not vibrations need to be suppressed. In the determination of 702, the determination may be based on whether or not the reading operation is being executed, but the reading speed, the reading resolution, or the operation purpose may be further considered. For example, when the reading speed is high or when the reading resolution is high, it is determined that it is easily affected by vibration. As another example, when the operation purpose is a pre-scan for analysis that does not require highly accurate reading, it is determined that the influence of vibration is not easily received. As yet another example, in the case of reading a copy operation to actually record an image or in the case of a PC scan where the read image may be used after being enlarged, it is affected by vibration. Judge that it is easy. Note that the present invention is not limited to the above example, and can be applied to cases other than the above example. If it is determined in 702 that it is not necessary to suppress vibrations, a setting is made to perform a normal supply operation (703). On the other hand, if it is determined in 702 that vibrations need to be suppressed, the operation is set so as to suppress vibrations (704). The setting contents in 704 may be selected in advance, and the selection of the setting contents may take into account the reading operation status and setting contents acquired in 701. Further, the setting content in 704 may be dynamically determined using the information acquired in 701. Further, in addition to the information related to reading described above, the information may be determined according to the type of recording medium.

  As described above, by controlling the recording medium supply operation as shown in the first embodiment of the present invention, it is possible to suppress the influence of vibration on the reading operation.

  In the first embodiment of the present invention, an example in which vibration generated when the pressure plate 404 in FIG. 4 collides with the supply roller 403 has been shown. In this embodiment, an example in which vibration generated when the recording medium 401 is pulled by the supply roller 403 is suppressed is shown. Since the present embodiment has substantially the same configuration as the first embodiment of the present invention, only differences from the first embodiment of the present invention will be described, and description of the same parts will be omitted.

  When the recording medium is pulled in, as shown in FIG. 5, when the supply roller 403 and the recording medium 401 come into contact, the recording medium 401 is dragged by the operation of the supply roller 403 due to friction. In recent years, the recording speed of recording apparatuses has been improved, and as a result, the supply speed of recording media has been increased. The recording medium 401 immediately before the supply operation is almost stationary on the recording medium holding unit 402, but the operation of pulling the recording medium 401 at a high speed from the stationary state rapidly changes the moving speed of the recording medium 401. As a result, it becomes a factor that generates vibration. In addition, when the supply operation speed is different from the recording speed, and particularly when the supply speed is higher, it is necessary to decelerate the recording medium rapidly after the supply operation. Then, suddenly changing the speed of the recording medium 401 becomes a factor that causes the recording apparatus to generate vibration. Further, when the center of gravity of the supply roller 403 is not on the rotation axis, vibration may be generated by the rotation of the supply roller 403 itself. 4 and 5, the supply roller 403 has a circular cross section, but the present invention is not limited to this. In this embodiment, a description will be given of an embodiment for suppressing vibration that occurs when the recording medium is pulled in when the recording medium is supplied.

  In this embodiment, an example in which vibration is suppressed by controlling the operation content of the supply roller 403 is shown. More specifically, in the flow of FIG. 7, which is a detailed description of the supply operation determination 601, when it is determined that the vibration needs to be suppressed in 702, the supply operation in which the vibration is suppressed is performed in 704. Set. At this time, as the content of the supply operation set in 704, control is performed so that the rotation speed of the paper feed roller 403 is reduced as compared with the normal supply operation. Alternatively, in order not to change the speed of the recording medium 401 abruptly, control is performed so that the acceleration is below a certain level.

  As described above, by controlling the recording medium supply operation as shown in the second embodiment of the present invention, it is possible to suppress the influence of vibration on the reading operation.

  In the first and second embodiments of the present invention, the example for suppressing the vibration generated when the recording medium is supplied has been shown. Incidentally, the vibration may occur not only when the recording medium is supplied but also when the recording medium is transported or discharged. In the present embodiment, an embodiment will be described for suppressing the influence of vibration generated during conveyance or ejection of a recording medium from affecting the reading operation.

  8 and 9 are diagrams for explaining the recording operation when an ink jet printer is taken as an example of the recording unit. Reference numeral 801 in FIG. 8 denotes a print head having several tens to several hundreds of ink ejection nozzles in the sub-scanning direction. Reference numeral 802 denotes a guide for causing the print head 801 to scan in the main scanning direction. The print head 801 reciprocates in the main scanning direction along the guide 802. On the other hand, the recording medium 401 is conveyed in a direction orthogonal to the main scanning direction in which the print head 801 can move. FIG. 9 is a diagram for explaining the operation of the print head 801 and the movement of the recording medium 401. Reference numeral 901 denotes a range in which the print head can eject ink by one reciprocating operation, and the print head 801 reciprocates over the region 901. In FIG. 9, Step 1 to Step 5 show the flow of the recording operation being executed. When the recording operation starts, the recording medium 401 is supplied into the recording apparatus and the recording operation is executed. In the recording operation, when the print head 801 is operating in the main scanning direction while ejecting ink, the conveyance of the recording medium is stopped (Step 1). When one scan of the print head is completed, the operation of the print head 801 is stopped while the recording medium is transported in the sub-scanning direction (Step 2). When the conveyance of the recording medium for one time is completed, the conveyance operation of the recording medium is stopped, and the print head 801 again performs the operation in the main scanning direction and the ink ejection (Step 3). Hereinafter, as in Step 4, Step 5,..., The recording operation is realized by repeatedly executing the same operation until the recording is completed.

  Incidentally, high-speed recording operations have been realized in recent inkjet printers. Therefore, the operation described with reference to FIG. 9 needs to be executed at high speed. When recording a plurality of copies, in order to supply and transport the next recording medium at high speed, it is necessary to discharge the recording medium after recording at high speed. However, as described in the second embodiment of the present invention, the operation of rapidly accelerating or decelerating the recording medium may increase the vibration generated by the recording medium itself or a conveyance system of the recording medium such as a roller. Then, the vibration may affect the reading operation. In the present embodiment, an embodiment for suppressing the vibration that occurs during conveyance and ejection of the recording medium as described above from affecting the reading operation will be described. More specifically, when it is necessary to suppress vibrations, the speed of the recording medium conveyance operation and the recording medium ejection operation is decreased than usual, or the acceleration is set to be lower than a certain level. Try to suppress vibration.

  FIG. 10 is a principal block diagram showing the configuration of the present embodiment. In the following description, the same reference numerals are given to the same items as the above-described items, and the description is omitted unless it is particularly necessary. In FIG. 10, when the operation instruction is issued and the recording setting is determined, the recording unit supplies the recording medium by the recording medium supply unit 1001. Then, when the recording medium is supplied and the recording operation is started, the conveyance operation determining unit 1002 acquires operation setting information such as the operation status of the reading unit 102 and the reading resolution. In the transport operation determining unit 1002, the content of the recording medium transport operation is determined in accordance with the acquired operation status and setting content of the reading unit. The recording unit 1003 performs a recording operation, and the conveyance operation is executed according to the contents determined by the conveyance operation determination unit 1002. When the recording operation is completed, the discharge operation determining unit 1004 acquires operation setting information such as the operation status of the reading unit 102 and the reading resolution. In the discharge operation determining means 1004, the content of the recording medium discharge operation is determined according to the acquired operation status and setting contents of the reading means. Then, the recording medium discharging means 1005 executes the recording medium discharging operation, and the operation of the recording unit is completed.

  Next, the flow of the present embodiment will be described with reference to FIG. In FIG. 11, items similar to those in FIG. 6 showing the operation flow of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. When the process is started, a recording medium supply operation is executed in 1101. When the recording medium is supplied into the recording apparatus, the recording operation is started, and the scanning 603 in the main scanning direction of the print head and the conveying operation of the recording medium are repeatedly executed until the recording is completed. In the recording medium conveying operation, first, the content of the conveying operation is determined (1102), and then the conveying operation is executed (1103) according to the determined content. When all the recording operations are completed, the recording medium is ejected. First, after determining the content of the discharging operation (1104), the discharging operation is executed (1105) according to the determined content.

  FIG. 12 shows the detailed operation content of the determination 1102 of the transport operation content. When carrying operation determination is performed, first, information 1201 indicating whether or not the reading operation is being executed or the setting contents of the reading operation is acquired. Then, based on the information acquired in 1201, it is determined 1202 whether it is necessary to suppress vibration. 1201 and 1202 may be the same as the information acquisition 701 and determination 702 in FIG. 7 described in the first embodiment of the present invention, but different information and different determination criteria may be used. . If it is determined in the determination 1202 that it is not necessary to suppress vibrations, settings are made to perform a normal supply operation (1203). On the other hand, if it is determined in 1202 that it is necessary to suppress the vibration, the operation is set so as to suppress the vibration (1204). Note that the setting contents in 1204 may be selected in advance, and the selection of the setting contents may take into account the reading operation status and setting contents acquired in 1201. The setting content in 1204 may be dynamically determined using the information acquired in 1201. Further, in addition to the information related to reading described above, the information may be determined according to the type of recording medium.

  The detailed operation content of the determination 1104 of the discharge operation content is shown in FIG. When the discharge operation is determined, first, acquisition 1301 of information such as whether or not the reading operation is being performed or the setting contents of the reading operation is performed. Then, based on the information acquired in 1301, it is determined 1302 whether or not it is necessary to suppress vibration. 1301 and 1302 may have the same contents as the information acquisition 701 and the determination 702 in FIG. 7 described in the first embodiment of the present invention, but different information and different determination criteria may be used. . Further, the information may be the same as the information acquisition 1201 and the determination 1202 in FIG. 12 described above, but different information or different determination criteria may be used. If it is determined in the determination 1302 that it is not necessary to suppress vibrations, a setting is made to perform a normal supply operation (1303). On the other hand, if it is determined in 1302 that the vibration needs to be suppressed, the operation is set so as to suppress the vibration (1304). The setting contents in 1304 may be selected from the predetermined setting contents, and the selection of the setting contents may take into account the reading operation status and the setting contents acquired in 1301. Further, the setting content in 1304 may be dynamically determined using the information acquired in 1301. Further, in addition to the information related to reading described above, the information may be determined according to the type of recording medium.

  In the present embodiment, an example of an ink jet printer is taken as an example of suppressing vibration during conveyance of a recording medium. However, the present invention is not limited to this, and can be applied to various devices in which vibration is suppressed by applying the present invention.

  In recent years, it has become possible for recording apparatuses to perform recording on various recording media. FIG. 14 and FIG. 17 are diagrams for explaining the present embodiment taking an ink jet printer as an example. In FIG. 14 and FIG. 17 to FIG. 17, parts unnecessary for the explanation are deleted, and only the parts necessary for the explanation are shown. As shown in FIG. 14, the recording apparatus can perform recording on a paper recording medium 1402 having a general thickness such as plain paper or photographic paper placed on an auto seed feeder 1401 at the rear of the apparatus body. is there. Further, as shown in FIG. 15, there is a device in which a manual paper feed port is provided at the rear of the apparatus main body, and in such a model, it is possible to supply a recording medium such as thick paper 1501 having a thickness greater than 1402. . In recent years, recording on a recording medium other than paper, such as recording on the surface of a disk medium such as a CD-R, has become possible. As a method for recording on the disk medium, a method of supplying the disk medium 1602 set on the tray 1601 from the outlet side as shown in FIG. 16 is performed. Then, after performing an operation of pulling the tray 1601 to the back, a method of conveying the tray 1601 while performing recording to the discharge port side is performed.

  FIG. 17 shows the state of the recording medium, the print head 801, and the transport roller 1403 during the recording operation. FIG. 17A shows a state in which a recording operation is performed on a recording medium having a general thickness as shown in FIG. The conveyance roller 1403 conveys the recording medium 1402 by rotating while sandwiching the recording medium 1402 from above and below. Further, the print head 801 discharges ink to the recording medium from a position away from the recording medium 1402 by a predetermined distance. FIG. 17B shows a recording operation on the disk medium shown in FIG. The tray 1601 that holds the disk medium 1602 is thicker than a general sheet 1402. Therefore, the recording operation is performed in a state in which the upper and lower intervals of the transport roller 1403 are widened. Further, since a predetermined distance is required between the print head 802 and the recording medium, the position of the print head 802 must be raised in the state of FIG. 17B compared to FIG. When recording on the thick paper 1501 as shown in FIG. 15, the distance between the transport rollers 1403 and the position of the print head 802 must be changed as in FIG. 17B.

  As described in the second and third embodiments of the present invention, the drive portion may generate vibration. For example, when the position of the print head 802 is raised or lowered, there is a possibility of mechanical collision with the rising limit position or the lowering limit position. In such a case, when the position adjustment of the print head is performed at high speed, the collision may cause vibration. Further, when recording is performed on a thick recording medium, it is necessary to sandwich the recording medium after the interval between the transport rollers 1403 is wider than that of a normal thickness recording medium. If a thick recording medium is supplied to the conveyance roller 1403 at high speed, the recording medium may collide with the conveyance roller 1403 before the interval between the conveyance rollers 1403 is sufficiently widened, which may generate vibration. . Alternatively, when the conveyance roller 1403 sandwiches the recording medium with a spring, when the recording medium passes between the conveyance rollers 1403, the interval between the conveyance rollers 1403 may be naturally increased. it can. However, even in this case, when the recording medium is moved at a high speed, the recording medium may try to pass between the conveying rollers 1403 before the interval between the conveying rollers 1403 is sufficiently widened. As a result, the recording medium collides with the transport roller 1403, and vibration may occur.

  As described above, in order to prevent the vibration described in this embodiment from affecting the reading operation, the position adjustment operation of the print head or the operation of supplying / conveying the recording medium having a thickness larger than that of a general recording medium is performed at a low speed. You just have to do it. For this purpose, as in the method described in the first, second, or third embodiment of the present invention, the reading operation is performed when the operation is started, or the current reading operation is affected by the vibration. It is preferable to detect information on whether or not it is easy to receive, and switch according to the information.

  In the present embodiment, an example of an ink jet printer is taken as an example of suppressing vibration during conveyance of a recording medium. However, the present invention is not limited to this, and can be applied to various devices in which vibration is suppressed by applying the present invention.

  As described above, the first to fourth embodiments of the present invention have been described with specific examples showing the contents of the present invention. The present invention may be further used in combination with the contents described in the above embodiments. By combining and adapting the contents described in the above-described embodiments, it is possible to suppress the influence of vibration generated by various factors on the reading operation.

  Also, in the above-described embodiment, an example is described in which the operation contents of the recording medium supply operation, the transport operation, and the discharge operation are determined according to the operation state and setting contents of the reading unit immediately before the execution of each operation. However, the present invention is not limited to this. For example, immediately after the operation instruction is given, a part or all of the recording medium supply operation, transport operation, and discharge operation may be determined. Or you may make it determine the content of discharge operation | movement at the time of the conditions of conveyance operation | movement. Furthermore, if an operation that suppresses vibration is selected when determining the operation content of one of the recording medium supply operation, transport operation, and discharge operation, vibration is suppressed for all subsequent operations. You may make it select the operation | movement to perform.
