In FIG. 7A, reference numeral 801 denotes a triangular wave generator, which generates a triangular wave having a predetermined frequency. A D / A converter (D / A converter) 802 converts an input digital image signal into an analog signal. The signal from the triangular wave generator 801 (the signal a in FIG. 7B) and the signal from the D / A converter 802 (the signal b in FIG. 7B) are compared in magnitude by the comparator 803. (B) is sent to the laser driver 804 as a signal c, and each of CMYK is converted into a laser beam by the laser oscillator 805 of each of CMYK.
[0050]
Then, the respective laser beams are scanned by the polygon scanner 913 to irradiate the respective photosensitive drums 917, 921, 925, and 929.
[0051]
[Configuration of Printer Unit 208 of MFP 104]
FIG. 8 is a sectional view for explaining the configuration of the MPFs 104a to 104d shown in FIG. 1, and shows an outline of, for example, a 4-drum type color printer unit.
[0052]
In FIG. 8, a polygon mirror 913 receives four laser beams emitted from four semiconductor laser oscillators 805. One scans the photosensitive drum 917 through mirrors 914, 915, and 916, the other scans the photosensitive drum 921 through mirrors 918, 919, and 920, and the other scans the mirror 922. , 923, and 924 to scan the photosensitive drum 925, and the next one scans the mirror 926, 927, and 928 to scan the photosensitive drum 929.
[0053]
On the other hand, reference numeral 930 denotes a developing unit for supplying yellow (Y) toner, which forms a yellow toner image on the photosensitive drum 917 in accordance with the laser beam, and 931 denotes a developing unit for supplying magenta (M) toner. According to the laser light, a magenta toner image is formed on the photosensitive drum 921, and a developing device 932 supplies cyan (C) toner. The developing device 932 forms a cyan toner image on the photosensitive drum 925 according to the laser light. , 933 are developing units for supplying black (K) toner, and form a black toner image on the photosensitive drum 929 according to the laser beam. The toner images of the four colors (Y, M, C, K) are transferred onto the sheet, and a full-color output image can be obtained.
[0054]
Sheets supplied from any of the sheet cassettes 934 and 935 and the manual feed tray 936 are sucked onto the transfer belt 938 via the registration rollers 937 and conveyed. Synchronous with the paper feed timing, the toner of each color is developed in advance on the photosensitive drums 917, 921, 925, and 929, and the toner is transferred to the sheet as the sheet is transported. The sheet onto which the toner of each color has been transferred is separated, transported by a transport belt 939, and the toner is fixed to the sheet by a fixing device 940.
[0055]
The sheet that has passed through the fixing device 940 is once guided downward by the flapper 950, and after the rear end of the sheet has passed through the flapper 950, the sheet is switched back and discharged. As a result, the sheets are discharged in a face-down state, and when printed in order from the first page, the order is correct.
[0056]
Note that the four photosensitive drums 917, 921, 925, and 929 are arranged at regular intervals with a distance d, and the sheet is conveyed at a constant speed V by the conveyance belt 939. Synchronization is performed at this timing. Then, the four semiconductor lasers 805 are driven.
[0057]
FIG. 9 is a block diagram for explaining a data processing mechanism of the printer unit of the MFP 104 shown in FIG. 1, and the same components as those in FIG. 2 are denoted by the same reference numerals.
[0058]
In FIG. 9, a print job is received by a NIC unit 204 via a network, the print job is analyzed by a PDL unit 205, pulse width modulated by a PWM unit 207, and output as an image signal to a printer unit 208. Thus, the printing process is executed.
[0059]
[Configuration of Display Unit 210]
FIG. 10 is a diagram illustrating a data display control mechanism of the display unit 210 illustrated in FIG.
[0060]
In FIG. 10, since the image signal output from the core unit 206 is CMYK data, it is necessary to convert the image signal into RGB data by the inverse LOG conversion unit 1001. Next, in order to match the color characteristics of the display device 1004 such as a CRT to be output, the gamma conversion unit 1002 performs output conversion using a look-up table. The converted image data is stored once in the memory unit 1003 and displayed on a display device 1004 such as a CRT.
[0061]
Here, the display unit 210 is used when a preview function for checking an output image in advance, a proof function for verifying that an output image is correct as intended, or a case where it is not necessary to check whether printing is necessary or not. This is to reduce waste of the print sheet.
[0062]
[Configuration of Finisher 209]
FIG. 11 is a schematic diagram illustrating the configuration of the finisher unit 209 illustrated in FIG.
[0063]
11, the sheet that has exited the fixing unit 940 (or 979) of the printer unit 208 enters the finisher unit 209. The finisher unit 209 includes a sample tray 1101 and a stack tray 1102, which are switched and discharged according to the type of job and the number of sheets to be discharged.
[0064]
There are two types of sorting methods, a bin sorting method having a plurality of bins and distributing to each bin, and an electronic sorting function described later and distributing output sheets for each job by shifting the bin (or tray) in the back / front direction. Sorting can be performed by a shift sort method.
[0065]
The electronic sort function is called collate, and if you have the large-capacity memory described in the core section above, you can use this buffer memory to change the order of buffered pages and the order of discharge, a so-called collate function. By using it, the function of electronic sorting can be supported. Next, the group function is a function for sorting pages, while sorting sorts the jobs for each job.
[0066]
Further, when the sheets are discharged to the stack tray 1102, the sheets before the sheets are discharged may be stored for each job, and bound by the stapler 1105 immediately before the sheets are discharged.
[0067]
In addition, before reaching the above two trays, there are a Z-folder 1104 for folding paper in a Z-shape and a puncher 1106 for making two (or three) holes for files. The respective processes are performed according to the requirements.
[0068]
Further, the saddle stitcher 1107 performs a process of binding the central portion of the sheet at two locations and then folding the sheet in half by bending the central portion of the sheet with a roller to create a booklet such as a weekly magazine or a pamphlet. . The sheet created by the saddle stitcher 1107 is discharged to a booklet tray 1108.
[0069]
In addition, although not shown in the drawing, it is also possible to add a binding by glue (glue) for bookbinding, or a cutting after the binding to align an end face opposite to the binding side.
[0070]
An inserter 1103 is for sending sheets set on the tray 1110 to any of the trays 1101, 1102, and 1108 without passing through a printer. As a result, a sheet set in the inserter 1103 can be inserted (inserted) between sheets fed to the finisher unit 209. The tray 1110 of the inserter 1103 is set by the user in a face-up state, and is fed by the pickup roller 1111 in order from the top sheet.
[0071]
Therefore, the sheet from the inserter 1103 is discharged face-down by directly discharging it to the trays 1101 and 1102. When sending the sheet to the saddle stitcher 1107, the sheet is sent once to the puncher 1106 side and then switched back to be sent to adjust the face direction.
[0072]
[Description of network utility software]
The following describes the U-utility software operating on the computers 102 and 103. A standardized database called MIB (Management Information Base) is built in a network interface portion (NIC unit 204 + PDL unit 205) in the MFP 104 and the LBP 105, and a network is managed via a network management protocol called SNMP (Simple Network Management Protocol). By communicating with the above computer, it is possible to manage the MFP 104, the LBP 105, and other scanners, printers, and faxes connected on the network.
[0073]
On the other hand, a software program called a utility runs on the computers 102 and 103, and necessary information can be exchanged by using the MIB by using the SNMP via a network.
[0074]
For example, the device information of the MFP 104 and the LBP 105 is acquired to detect whether the finisher unit 209 is connected, the status information is acquired to detect whether the current print is possible, or the MFP 104 and the LBP 105 are acquired. By using the MIB, the user can check the information on the MFP 104 and the LBP 105 connected to the network on the computers 102 and 103, for example, by entering, changing, and confirming the name and the installation location. In addition, such information can be used to limit reading and writing by distinguishing the server 102 and the client 103.
[0075]
Therefore, by using this function, the user can obtain all kinds of information such as the equipment information of the MFP 104 and the LBP 105, the state of the apparatus, the network setting, the history of the job, the management of the use status, and the control in front of the computers 103 and 102. Becomes possible.
[0076]
[Configuration of LBP 105]
Next, the configuration of the LBP 105 will be described with reference to FIG.
[0077]
FIG. 12 is a schematic sectional view illustrating the configuration of the LBP 105 shown in FIG. 1, and corresponds to a one-drum type color printer unit.
[0078]
The LBP 105 develops a page description language (PDL) transmitted from the NIC (Network Interface Card) unit 204 for exchanging image data and apparatus information using a network into an image signal. It has a PDL unit 205. The configurations of the NIC unit, PDL unit, and PWM unit are the same as those of the MFP 104.
[0079]
In FIG. 12, reference numeral 913 denotes a polygon mirror which receives a single laser beam emitted from the semiconductor laser 805, scans the photosensitive drum 917 through the mirror 914, and forms a latent image on the photosensitive member. The latent image on the photoreceptor reaches the color developing unit 961 and the black developing unit 960 while rotating counterclockwise. Each of the developing devices 961 and 960 has a function of applying (developing) toner in accordance with the charge charged as a latent image on the photoconductor 917.
[0080]
When the image is black and white, only the black developing device 960 is used, and when the image is color, both developing devices 960 and 961 are used. Next, the image generated on the photoconductor 917 is transferred to the intermediate transfer body 962 that is rotating clockwise. This intermediate transfer member completes image formation on the intermediate transfer member by making one rotation for black and white and four rotations for color.
[0081]
The color developing unit 961 is controlled so that any one of the yellow developing unit 961y, the magenta developing unit 961m, and the cyan developing unit 961c is brought into contact with the photosensitive drum 917 by rotating. First, when developing and transferring the yellow toner, the color developing device rotates until the position shown in FIG. 10 is reached, and when the laser exposure is performed on the photosensitive drum 917, the drum rotates clockwise in synchronization with the yellow developing device. By 961y, a yellow toner image is formed on the photosensitive drum 917.
[0082]
In synchronization with this, the transfer drum 962 rotates counterclockwise, and the yellow toner is transferred from the photosensitive drum 917. The length around the transfer drum 962 is such that an A3-size image can be formed in the longitudinal direction. When forming an A3-size image, an A3-size original is read and a yellow toner image for one A3-size image is formed on the transfer drum 962 based on the image signal.
[0083]
Next, when developing and transferring magenta toner, after the color developing device rotates 120 degrees counterclockwise, the original is read in the same manner as described above, and laser exposure is performed on the photosensitive drum 917 according to the image signal. Synchronously, the drum rotates clockwise, and a magenta toner image is formed on the photosensitive drum 917 by the magenta developing device 961m. In synchronization with this, the transfer drum 962 rotates counterclockwise, and the magenta toner is transferred from the photosensitive drum 917.
[0084]
Next, a cyan toner image is similarly transferred. Next, a black toner image is formed on the photosensitive drum 917 by the developing device 960, and is similarly transferred.
[0085]
