The present disclosure relates to a printing apparatus, a control method for the printing apparatus, and a storage medium.
Up to now, a technology has been proposed in which a control apparatus analyzes a copy job where an execution instruction is accepted, and a sheet feeding reservation is thereafter issued to a printer apparatus in accordance with the number of pages of a document read by a reader apparatus and a set value set by an operation unit. For example, in a case where printing is performed on the basis of one-sided printing and also 2-in-1 (reduced layout), when generation of image data for two pages is ended, the control apparatus issues a sheet feeding reservation to the printer apparatus. Subsequently, the printer apparatus feeds a sheet from a specific sheet holding unit in response to the reception of the sheet feeding reservation (see Japanese Patent Laid-Open No. 2012-27236).
Up to now, since the sheet is fed from the sheet holding unit after a storage area for storing the image data generated by reading the image of the document, a delay for starting the feeding of the sheet from the sheet holding unit occurs. For this reason, it takes time to output a printed product.
According to an aspect of the present disclosure, there is provided a printing apparatus including: a feeding unit configured to feed a sheet from a sheet holding unit; a reading unit configured to read an image of a document; a storing unit configured to store image data of the document read by the reading unit; and a printing unit configured to read out, before image data for one page of the document is stored in the storing unit, the image data of the document from the storing unit and print the image on the sheet fed from the sheet holding unit by the feeding unit based on the read image data, in which the feeding unit is able to start to feed the sheet from the sheet holding unit before the image data for the one page of the document is stored in the storing unit.
Further features of the present invention will become apparent from the following description of exemplary embodiments with reference to the attached drawings.
Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that the following exemplary embodiments are not designed to limit the present disclosure related to the scope of the claims, and not all of combinations of characteristics described in the exemplary embodiments of the present disclosure are necessarily indispensable to address the issues of the present disclosure.
A printing apparatus according to a first exemplary embodiment will be described with reference to
According to the first exemplary embodiment, before a storage area for storing scanning image data is secured in a RAM 506, a controller unit 500 issues a command for starting to feed a sheet from a feeding unit 604. Subsequently, an image forming unit 600 starts to feed the sheet from the feeding unit 604 in response to the reception of this command. As a result, in a case where an image of a document is read, a time until the image is output to a sheet on the basis of image data generated by reading the document (which will be referred to as a first copy out time: FOOT) is shortened.
Hereinafter, details of the exemplary embodiments of the present disclosure will be described.
A printing apparatus according to the present exemplary embodiment is, for example, the MFP 1000 provided with an image reading function of reading an image of a document and generating image data and a printing function (copying function) of printing the image on a sheet on the basis of the generated image data. MFP stands for multi functional peripheral. It should be noted that the MFP 1000 may be provided with a printing function (PC printing function) of receiving a printing job from an external apparatus, such as a PC, and printing a character or an image on a sheet on the basis of this printing job.

The ROM 401 is a read-only memory and stores a control program and a fixed parameter in advance. The RAM 402 is a memory where read and write can be performed and stores input data and working data.
The CPU 400 controls conveyance of the document 32 in accordance with the control program stored in the ROM 401. The CPU 400 also performs a serial communication with a CPU 421 of the image reading unit 200 via a control communication line 451 and transmits and receives control data with the ADF 100 and the image reading unit 200. The CPU 400 also transmits a signal representing a page start of the image data of the document 32 to the image reading unit 200 via the control communication line 451.
Control Block of the Image Reading Unit 200
The image reading unit 200 is provided with the CPU 421, a ROM 422, a RAM 423, a sheet interval correcting unit 424, an image processing unit 425, an optical system motor drive unit 426, an optical lamp 203, and a CCD sensor unit 210 as a plurality of function blocks. CCD stands for a charge coupled device. These components are electrically connected to one another via a control bus line 430 and mutually transmit and receive the control commands and the data. It should be noted that, in the CCD sensor unit 210, a monochrome image reading CCD 211 configured to read the image of the document in black and white is connected to a CCD controlling unit 213 via an image data communication line 214 including a clock signal line for the image transfer. In addition, in the CCD sensor unit 210, a color image reading CCD 212 configured to read the image of the document in color is connected to the CCD controlling unit 213 via an image data communication line 215 including the clock signal line for the image transfer.

The image processing unit 425 is a unit configured to perform various image processings such as shading correction on the image data generated by the reading of the image of the document.
The CPU 421 performs control on the conveyance of the document 32 by the ADF 100 and control on the reading of the image of the document 32 by the image reading unit 200. For example, the CPU 421 transmits a command related to the control of the conveyance of the document 32 via the control communication line 451 and instructs the CPU 400 to control the conveyance of the document 32. Subsequently, the CPU 400 that has been instructed to control the conveyance of the document 32 performs the control to monitor the various sensors 404 installed on a conveying path and drive the motor 403 for the conveyance, the solenoid 406, and the clutch 407 so as to convey the document 32.
For example, the CPU 421 also controls the optical system motor drive unit 426 corresponding to a driver circuit configured to drive an optical system driving monitor. In addition, for example, the CPU 421 controls the image processing unit 425 connected on the control bus line 430.

Details of the exemplary embodiment will be described below. During a process of scanning the image of the document by the CCD sensor unit 210, an image signal is formed on the CCD sensor unit 210 (either the color image reading CCD 212 or the monochrome image reading CCD 211) by a lens 207. Subsequently, an analog image signal read for each line by the CCD sensor unit 210 is output to the CCD controlling unit 213 from the image data communication line 214 or the image data communication line 215. Subsequently, the CCD controlling unit 213 converts the analog image signal into digital image data. Subsequently, the image processing unit 425 performs various image processings on the converted image data, and thereafter, the CPU 421 writes the image data in an image memory 429 via an image data communication line 455 including the clock signal line for the image transfer.
The CPU 421 transmits the image data written in the image memory 429 to the controller unit 500 via an image data communication line 453 of a controller interface including the clock signal line for the image transfer. The CPU 421 also transmits a signal representing a page start of the image data of the document to the controller unit 500 via a control communication line 452 of the controller interface to adjust a transfer timing of the image data.
In addition, the CPU 421 similarly transmits a signal representing a page start of the image data notified from the ADF 100 via the control communication line 451 to the controller unit 500 via the control communication line 452.

The HDD 509 also stores predetermined user information related to the user who logs in to the MFP 1000 (for example, a user ID, a user name, a password, and the like). The HDD 509 also stores an affiliation correspondence table 7000 which will be described below with reference to
The ROM 507 or the HDD 509 stores various control programs used for executing various processings of flow charts by the CPU 501 which will be described below. The ROM 507 or the HDD 509 also stores a display control program for causing a display unit of the operation unit 505, which will be described below, to display various user interface screens (will be referred to as user interface (UI) screens below). The CPU 501 reads out the program stored in the ROM 507 or the HDD 509 and executes various operations related to the present exemplary embodiment by decompressing this program in the RAM 506.
The scanner I/F 503 is an interface for connecting the controller unit 500 to the image reading unit 200. In the scanner I/F 503, the image data is cut out for the number of lines in accordance with a register value in the scanner I/F 503.

Subsequently, the CPU 501 transmits the image data written in the RAM 506 to the image forming unit 600 via the printer I/F 508 through an image data communication line 457 of the controller interface including the clock signal line for the image transfer.
The image processing circuit 502 executes image conversion processing on the image data stored in the RAM 506 in accordance with the register value in the image processing circuit 502 and thereafter stores the converted image data in the RAM 506 again.

The operation unit 505 is relevant to an example of a user interface unit.
It should be noted that the display unit 710 is constituted as a touch panel sheet including a liquid crystal display (LCD) and transparent electrodes affixed on the LCD (which may be of a capacitance method). Buttons for setting a number of copies 711, color selection 712, magnification 713, and sheet selection 714 are arranged in the LCD as examples of basic settings for copying. As settings other than the basic settings for copying, for example, the user can set page printing, page layout, binding, and the like by pressing a button for setting other functions 719. It should be noted that a shortcut button can be created on a copy screen for a function frequently used by the user among the settings other than the basic settings for copying. For example, buttons for duplex 715 for setting duplex printing, density 716 for setting the printing density, document size mixed stack 717 for reading the documents having different sizes, long length 718 for reading the document having a length longer lengthwise or crosswise than a formatted size, and the like are arranged.

Control Block of the Image Forming Unit 600
The image forming unit 600 includes a CPU 601, a discharge unit 602, a marking unit 603, the feeding unit 604, and a finisher unit 605 as a plurality of function blocks. These components are electrically connected to one another via a bus controller 606 and mutually transmit and receive the control commands and the data.
The feeding unit 604 is constituted by a plurality of cassettes for holding sheets 301 used for printing and a manual feeding tray. The marking unit 603 is a unit configured to perform transferring and fixing of a toner (developing agent) image formed on the basis of the image data on the sheet 301 fed from the feeding unit 604 and form (print) the image on the sheet 301 by using the toner. It should be noted that details of the transferring and the fixing will be described below with reference to
The CPU 601 controls the image forming unit 600. For example, in a case where the marking unit 603 completes preparations for the image formation, the CPU 601 transmits a signal representing page start of the image data (such as start of the first page or start of the second page) to the controller unit 500 via a control communication line 456 of the controller interface. This operation is performed to adjust a transfer timing. Subsequently, the marking unit 603 performs the transferring and the fixing of the toner image on the basis of the image data transmitted via the image data communication line 457 of the controller interface.
An operation of the ADF 100 will be described with reference to
The feeding roller 1 drops onto a document surface of the sheaf of the documents set on the document tray 30 and rotates. As a result, the document 32 on the uppermost surface of the sheaf of the documents is fed. The plurality of documents 32 fed by the feeding roller 1 are separated into one sheet each to be fed by actions of a separation roller 2 and the separation pad 21. This separation is realized by a retard separation technique in related art.
The document 32 separated by the separation roller 2 and the separation pad 21 is conveyed to a registration roller 4 by a conveying roller pair 3. Subsequently, the conveyed document 32 abuts against the registration roller 4. As a result, the document 32 is formed into a loop shape, and skew in the conveyance of the document 32 is cancelled. A feeding path is arranged in the downstream side of the registration roller 4. The document 32 that has passed through the registration roller 4 is conveyed through the feeding path in a direction of a stream reading glass 201.
The document 32 conveyed through the feeding path is conveyed onto a platen by a large roller 7 and a feeding roller 5. Herein, the large roller 7 comes in contact with the stream reading glass 201. The document 32 conveyed by the large roller 7 passes through a conveying roller 6 and moves between a roller 16 and a movement glass.
Subsequently, the document 32 is discharged to a document discharge tray 31 via a discharge flapper and a discharge roller 8.
The ADF 100 can read an image on a rear surface of the document 32 by reversing the document 32. Specifically, the discharge roller 8 is reversed to switch the discharge flapper in a stage in which the document 32 is engaged with the discharge roller 8, and the document 32 is moved to a reversing path 19. The moved document 32 abuts against the registration roller 4 from the reversing path 19, and the document 32 is formed into a loop shape again, so that skew in the conveyance of the document 32 is cancelled. Thereafter, the document 32 is moved to the stream reading glass 201 again by the feeding roller 5 and the large roller 7, and the image on the rear surface of the document 32 can be read by the stream reading glass 201.
A guide regulating plate 15 that can slide in the sub scanning direction of the sheaf of the set documents is provided to the document tray 30, and a document width detection sensor (not illustrated) configured to detect a document width in conjunction with the guide regulating plate 15 is also provided. A size of the document 32 in the sheaf of the documents set on the document tray 30 can be determined by a combination of this document width detection sensor and a pre-registration sensor 11. In addition, a document length can be detected by a document length detection sensor (not illustrated) provided in the conveying path on the basis of a conveyance distance from leading end detection to rear end detection of the currently conveyed document 32. The size of the document can also be determined from a combination of the detected document length and the above-described document width detection sensor.
With regard to a document 32 on a platen glass 202, the image reading unit 200 optically reads image information recorded on the document while an optical scanner unit 209 performs scanning in the sub scanning direction indicated by an arrow of
The image information read by this optical system is photoelectrically converted and input to the controller unit 500 as image data. It should be noted that a white board 219 is used for creating reference data of a white level based on shading.
It should be noted that, according to the present exemplary embodiment, the descriptions have been given of a case where the optical system provided to the image reading unit 200 is a reduction optical system in which reflected light from the document is imaged on the CCD sensor, but the configuration is not limited to this. The optical system provided to the image reading unit 200 may be an equal magnification optical system in which the reflected light from the document is imaged on a contact image sensor (CIS).
Subsequently, the arrangement of the sensors configured to detect the size of the document set on the platen glass 202 will be described with reference to a top view of the platen glass 202 illustrated in
The optical scanner unit 209 is a unit configured to detect the size of the document 32 in the main scanning direction. Reflection-type sensors 220 and 221 are sensors configured to detect the size of the document 32 in the sub scanning direction.
When the ADF 100 is opened by the user to set the document 32 on the platen glass 202, the CPU 421 detects that the ADF 100 is opened. Subsequently, the CPU 421 causes the optical scanner unit 209 to move to a position where the set document 32 can be read.
The size of the document 32 set on the platen glass 202 in the sub scanning direction is detected by the plurality of reflection-type sensors 220 and 221 arranged as illustrated in
Subsequently, when the user starts to perform an operation for closing the ADF 100, the optical lamp 203 is turned on to illuminate the document 32 while the ADF 100 is being closed. Subsequently, the monochrome image reading CCD 211 (or the color image reading CCD 212) reads a certain line of the document 32 in the main scanning direction. With regard to the light from the optical lamp 203, a part where the light is shielded and reflected by the document 32 and a part where the reflected light is not shielded and returned since the document 32 does not exist are detected, and end parts of the document 32 are detected on the basis of the detection results. Since the document size of the formatted size can be confirmed by the thus detected length in the main scanning direction and an approximate length in the sub scanning direction, the document size is confirmed.
A reason why the detection in the sub scanning direction is performed to such an extent that a length can be classified into an approximate length is that the length in the main scanning direction can be precisely detected to some extent. For example, in a case where the length in the main scanning direction for the A4 size can be detected as the length in the main scanning direction, when both the reflection-type sensors 220 and 221 in the sub scanning direction detect the reflected light from the document, this size can be confirmed as the A3 size. When both the reflection-type sensors 220 and 221 do not detect the reflected light, this size can be confirmed as the A4 size. According to the present exemplary embodiment, the case has been described where the size is confirmed by detecting the size of the read document 32 by the sensors 220 and 221, but the configuration is not limited to this. In the MFP 1000 that is not provided with a sensor configured to detect the size of the read document, the size may be confirmed while the user inputs the size of the read document 32 from the operation unit 505.
Subsequently, an operation (printing operation) of outputting an image to the sheet 301 on the basis of the image data transmitted (transferred) to the image forming unit 600 will be described below.
The image data transmitted (transferred) to the image forming unit 600 is converted into laser light by a laser unit 322 in accordance with the image data. Subsequently, photosensitive drums 323 to 326 are irradiated with this laser light, and electrostatic-latent images in accordance with the image data are formed on the photosensitive drums 323 to 326. Toner (developing agent) is adhered to parts corresponding to the latent images of the photosensitive drums 323 to 326 by developing units 327 to 330. It should be noted that a color printer is provided with four each of photosensitive drums 323 to 326 and developing units 327 to 330 for cyan, yellow, magenta, and black.
The image forming unit 600 is also provided with the feeding unit 604, and the feeding unit 604 includes cassettes 351 to 354 and a manual feeding tray 350 as a sheet holding unit (also referred to as a sheet feeding deck). It should be noted that the cassettes 351 to 354 have a slide-out shape and can hold the plurality of sheets 301 (for example, 600 sheets). On the other hand, the manual feeding tray 350 has a plug-in shape and can hold the plurality of sheets sheet 301 (for example, 100 sheets).
The image forming unit 600 feeds the sheet 301 from any one of the cassettes 351 to 354 and the manual feeding tray 350. Subsequently, with respect to the fed sheet 301, the toner adhered to the photosensitive drums 323 to 326 is transferred to the sheet 301, and thereafter, the sheet 301 is conveyed to a fixing unit 333. Subsequently, the toner is fixed onto the sheet 301 by heat and pressure. The sheet 301 that has passed through the fixing unit 333 is conveyed to the finisher unit 605 by conveying rollers 334 and 335.
The sheet conveyed to the finisher unit 605 is first conveyed to a buffer unit 241 of the finisher unit 605. Herein, the conveyed sheet is wound around a buffer roller to perform buffering in accordance with the case. For example, in a case where the stapling processing or the like to be performed in the downstream thereof takes time, it is possible to adjust a conveyance interval of the sheets conveyed from the main body by using the buffer unit 241. Thereafter, the sheet passes through a conveying path 244 by an upstream discharging roller pair 242 and a downstream discharging roller pair 243 to be stacked on a stack tray 245. When the sheaf of sheets for one set of copies are stacked on the stack tray 245, the sheaf of stacked sheets pass through a conveying path 248 and are discharged to a discharging tray 247 functioning as a discharge unit.
In a case where the shifting is specified, the sheaf of sheets stacked on the stack tray 245 are discharged to the discharging tray 247 functioning as the discharge unit while being shifted with respect to the sheaf of sheets discharged immediately before, so that it becomes easier for the user to find a break between the copies. On the other hand, in a case where the stapling is specified, a stapling unit 246 performs stapling processing on the sheaf of sheets that are conveyed by the upstream discharging roller pair 242 and pass via the conveying path 244 by the downstream discharging roller pair 243 to be stacked on the stack tray 245. The sheaf of stapled sheets are discharged to the discharging tray 247 by the downstream discharging roller pair 243.
It should be noted that, in the MFP 1000 that is not provided with the finisher unit 605, the sheet that has passed through the fixing unit 333 may be directly discharged to the discharging tray 247 by the conveying rollers 334 and 335. In addition, in the MFP 1000 that is not provided with the discharging tray 247 functioning as the discharge unit, the sheet that has passed through the fixing unit 333 may be discharged into a barrel functioning as the discharge unit.
It should be noted that the descriptions have been given of a case where the MFP 1000 according to the present exemplary embodiment is the color printer provided with four each of the photosensitive drums 323 to 326 and the developing units 327 to 330, but the configuration is not limited to this. The subject aspect of the present disclosure can be similarly applied to the MFP 1000 even when the MFP 1000 is a monochrome printer provided with one each of the photosensitive drum and the developing unit. In addition, the method of printing the image on the sheet 301 by way of an electrophotographic method in the MFP 1000 according to the present exemplary embodiment has been described, but the configuration is not limited to this. As long as the image can be printed on the sheet 301, for example, an ink-jet method or the like may be adopted, and the other method (for example, a thermal-transfer method or the like) may also be adopted.
According to the first exemplary embodiment, the controller unit 500 issues the command for starting to feed the sheet from the feeding unit 604 before the storage area for storing the scanning image data is secured in the RAM 506. Subsequently, the image forming unit 600 starts to feed the sheet from the feeding unit 604 in response to the reception of this command. As a result, for example, in a case where the image of the document is read, the time (FOOT) until the image is output to the sheet on the basis of the image data generated by reading the document is shortened.
Details of the above-described configuration will be described below.
With reference to flow charts illustrated in
In S1001, the CPU 501 determines whether or not the user has logged in to the MFP 1000. It should be noted that, after the user inputs, for example, the predetermined user information (for example, the user ID, the user name, the password, and the like) to the authentication screen (not illustrated), the user logs in to the MFP 1000 by pressing a login button (not illustrated) on the authentication screen (not illustrated). When it is determined that the user has logged in to the MFP 1000, the CPU 501 advances the processing to S1100 which will be described below with reference to
It should be noted that, with regard to the login to the MFP 1000, a method of causing the CPU 501 to obtain user information may be employed by reading the user information from a card owned by the user with use of a card reading unit (not illustrated). It should be noted that all of a user ID, a user name, and a password are not necessarily needed for the user information, and only the user ID and the user name may constitute the user information.
Details of the series of processing for checking count values (the number of times to perform scanning and the number of times to perform printing) in the department to which the logged-in user belongs in the MFP 1000 according to the first exemplary embodiment will be described with reference to a flow chart illustrated in FIG. 6. This processing is executed while the CPU 501 of the controller unit 500 executes the control program read out from the ROM 507 or the HDD 509 and decompressed to the RAM 506.
In S1101, the CPU 501 obtains the information (for example, the user ID, the user name, the password, and the like) of the logged-in user in S1001 in
In S1102, the CPU 501 refers to the affiliation correspondence table 7000 illustrated in
In S1103, the CPU 501 refers to the department count table 7100 illustrated in

The above-described explanations relate to the details of the processings different from the processings according to the first exemplary embodiment among the series of processings for accepting the execution instruction of the copy job and executing the copy job where the execution instruction is received in the MFP 1000 according to the second exemplary embodiment.
Various examples and exemplary embodiments of the present disclosure have been described above, but the gist and the scope of the present disclosure should not be limited to the specific descriptions in the present specification for a person skilled in the art.
For example, according to the present exemplary embodiment, the case has been described where the CPU 501 does not issue the first scanning command in a case where the document is set in the ADF 100, but the configuration is not limited to this. Even in a case where the document is set in the ADF 100, the CPU 501 may issue the first scanning command when the copy settings such as the color mode, the magnification, and the sheet feeding deck satisfy a predetermined condition. In addition, the case has been described where the CPU 501 issues the first scanning command in a case where the copy settings such as the color mode, the magnification, and the sheet feeding deck satisfy the predetermined condition, but the configuration is not limited to this. A further restriction may be set such that the CPU 501 can issue the first scanning command in a case where the other copy settings such as the specification of the number of copies and settings of the reading resolution and the post processings satisfy a predetermined condition. As an alternative to the above-described configuration, a mode in which the copy settings such as the color mode, the magnification, and the sheet feeding deck are fixed (referred to as an FCOT shortened mode) can be directly specified from the operation unit 505 by the user. The CPU 501 may issue the first scanning command in a case where the FCOT shortened mode is specified by the user.
In addition, according to the present exemplary embodiment, the descriptions have been given while the PC is exemplified as the external apparatus, but a mobile information terminal such as a PDA or a smart phone, a network connecting device, an external dedicated-use apparatus or the like may be used instead.
In addition, according to the present exemplary embodiment, the CPU 501 of the controller unit 500 of the MFP 1000 functions as the main body for the above-described various controls, but a configuration may be adopted in which a part or all of the above-described various controls can be executed by a printing control apparatus such as an external controller corresponding to a separate package from the MFP 1000.
