Description

  The present invention relates to an image forming apparatus, and more particularly to an image forming apparatus having an auto-clear function for resetting the setting of the apparatus to a predetermined standard setting.

  In recent years, digital multifunction peripherals having a plurality of functions such as a copy, a facsimile, a printer, and a scanner have been widely used. In such a multifunction peripheral, the user can set various items such as the paper size and orientation, the number of copies, the magnification, and the density as the initial state of the apparatus. When the user makes a copy with a setting different from the standard setting, the user changes the setting to a desired setting (hereinafter referred to as a user setting) before copying.

  In the auto clear function, for example, if there is no operation until a predetermined time elapses after the job is completed, the setting by the user is automatically canceled and the setting of the apparatus is returned to the standard setting. Thereby, it is possible to avoid obtaining an unintended result by another user with the changed setting.

However, the user's setting instruction may be automatically cleared against the user's intention. For example, if a certain amount of time elapses while the user is troublesome to set up, or if it is necessary to leave the front of the multifunction device due to an emergency task (for example, when a call is received) The auto clear function will be executed before the user setting is completed. In preparation for such a case, for example, Patent Document 1 below describes an image forming apparatus that returns the setting of the apparatus to the user setting before the execution of the auto-clear function even after the auto-clear function has been executed. ing. According to this, it is only necessary to perform subsequent settings from the setting state that has been performed halfway, and it is possible to quickly reset to the desired user settings.
Japanese Patent Laid-Open No. 11-45032

  However, even if the user setting before the execution of the auto-clear function is restored, the setting contents are halfway from what the user originally wants to set because the setting was in progress. For this reason, it is difficult to know how far the user setting has been made, and when the user setting is continued, it is necessary to check whether the setting item is a standard setting item or a user setting item.

  The present invention proposes to solve the above-described conventional problems, and it is clear how far the user setting has been made before the execution of the auto clear function, and it is possible to easily determine where to set next. It is an object of the present invention to provide an image forming apparatus that can be used.

  The image forming apparatus of the present invention displays standard setting items when the setting of the apparatus is a standard setting, and sets the user setting when the setting of the apparatus is changed from the standard setting to the user setting by the user. It is assumed that items are displayed.

  The image forming apparatus of the present invention includes a storage unit that stores the setting contents of the user setting, and an auto-clear that resets the setting of the apparatus to a predetermined standard setting when a user does not perform an operation during the user setting for a predetermined time. And auto-clear canceling means for returning the setting of the apparatus from the standard setting to the user setting based on a user operation after the auto-clearing means is executed. The auto-clear canceling unit can return from the standard setting to the user setting by reading the contents of the user setting stored in the storage unit.

  Further, the image forming apparatus includes a display unit that displays, when the auto-clear canceling unit is executed, a user setting item before the auto-clearing unit is executed in a format different from the standard setting item.

  For example, the display unit may display the user setting item and the standard setting item with different colors. In addition to changing the color of the user setting item and the standard setting item, for example, one setting item may be displayed as a solid line and the other setting item as a broken line. Alternatively, only one setting item may be displayed blinking.

  As described above, by changing the display format of the user setting item and the standard setting item (that is, the item that is not set by the user), whether the displayed setting item is based on the standard setting or not Make the distinction between settings different. As a result, it becomes clear how far the user has set before the auto-clearing means is executed, and it is possible to easily determine where the setting should be resumed next.

  According to the image forming apparatus of the present invention, when the setting of the apparatus is returned to the user setting after the execution of the auto-clearing means, it is immediately known how far the user setting has been made before the execution of the auto-clearing means, and the auto-clearing means is released. The user settings can be continued immediately after this.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In this embodiment, the present invention is embodied as a digital copying machine.

  FIG. 1 is a diagram showing an overall configuration of a copying machine according to the present embodiment. The digital copying machine 101 includes an image reading unit 102 and an image forming unit 103, and a document feeder 104 is attached to the upper side of the image reading unit 102 so as to be opened and closed. The user places a document on a document table 105 such as contact glass disposed on the upper surface of the casing of the image reading unit 102 or on the document feeding device 104.

  The image reading unit 102 reads an image of a document and generates digital data of the image. The image reading unit 102 includes a line image sensor 106 and a scanning optical system 107 below the document table 105. The scanning optical system 107 guides the reflected light image from the document to the line image sensor 106. The scanning optical system 107 includes a linear light source 108 and mirrors 109 to 111 arranged along a main scanning direction parallel to the line image sensor 106. A light source 108 illuminates the document, and mirrors 109 to 111 guide reflected light from the document to the light receiving surface of the line image sensor 107. The light source 108 and mirrors 109 to 111 can reciprocate in the sub-scanning direction. By moving the light source 108 and the mirrors 109 to 111 in the sub-scanning direction, a two-dimensional image of the document placed on the document table 105 can be read by the line image sensor 106. The image sensor 106 generates image data of a document from a light image incident on the light receiving surface.

  The image reading unit 102 can also read an image of a document placed on the document feeder 104. The document feeder 104 includes a document tray 112, a conveyance path 113, and a paper discharge tray 114. The document feeder 104 feeds the documents set on the document tray 112 one by one to the transport path 113. There is an image reading position 115 on the conveyance path 113. When reading an image of a document set on the document feeder 104, the image reading unit 102 temporarily fixes the positions of the light source 108 and the mirrors 109 to 111 in the sub-scanning direction to the image reading position 115. When the document on the conveyance path 113 passes through the image reading position 115, the document is illuminated by the light source 108 and the image of the document is read. The document that has passed the image reading position 115 is discharged to the paper discharge tray 114.

  The image forming unit 103 prints image data obtained by the image reading unit 102 or image data received from another device via a network on a sheet. The image forming unit 103 is provided with a photosensitive drum 116. This photosensitive drum 116 rotates in the direction of arrow 117 at a constant speed. Around the photosensitive drum 116, a charger 118, an exposure device 119, a developing device 120, a transfer device 121, and the like are arranged in this order from the upstream side in the rotation direction. The charger 118 uniformly charges the surface of the photosensitive drum 116. The exposure device 119 irradiates the uniformly charged surface of the photosensitive drum 116 with light according to image data, and forms an electrostatic latent image on the photosensitive drum 116. The developing device 120 attaches toner to the electrostatic latent image and forms a toner image on the photosensitive drum 116. The transfer device 121 transfers the toner image on the photosensitive drum 116 to a sheet. By rotating the photosensitive drum 116, these processes are performed in series.

  The image forming unit 103 feeds paper from the paper feeding cassettes 122 to 124 or the paper feeding device 125 to the transfer unit between the photosensitive drum 115 and the transfer device 121. The paper feed cassettes 122 to 124 are arranged below the image forming unit 103 and each store about 500 sheets. The sheets from the sheet feeding cassettes 122 to 124 are conveyed to the registration rollers 127 by the conveying rollers 126. The registration roller 127 feeds the sheet to the transfer unit in synchronization with the reading of the document. The sheet on which the toner image is transferred by the transfer unit is conveyed to the fixing device 130. The fixing device 130 includes a fixing roller 131 and a heating roller 132, and fixes the toner image on the sheet by heat and pressing force. The image forming unit 103 discharges the sheet that has passed through the fixing unit 130 to the discharge tray 133.

  FIG. 2 is a diagram showing an example of the appearance of the operation panel in the copying machine. The user can use the operation panel 201 to give a copy start and other instructions to the copying machine as described above, and to check the state and settings of the copying machine. On the operation panel 201, a display 202 with a touch panel and operation keys 203 are arranged.

  The display 202 displays an operation screen having a setting unit 204 and a message display unit 205.

  The setting unit 204 is provided with areas for setting the paper size and orientation, copy magnification, density, and the like. The setting unit 204 can initially set the copying machine as a standard setting. The standard setting items include various items such as paper size, orientation, number of copies, magnification, and density, and each setting item is set to a state most frequently used by the user. For example, the paper size is set to “automatic paper”, the number of copies is set to “1 copy”, the magnification is set to “same size”, and the density is set to “normal”. The setting items set as standard are displayed on the setting unit 204. For example, standard setting items are displayed in black, and items that are not set are displayed in white. The user sees this display and confirms how the current copying machine is set, that is, the standard setting.

  The user can also change the setting of the copying machine from the standard setting to a desired setting (user setting) by the setting unit 204. For example, if you want to enlarge the magnification to 1.5 times, enter “150%” in the magnification field, and if you want to copy 5 copies, enter “5 copies” in the number field. The content changed from the standard setting to the user setting is displayed on the setting unit 204. For example, the setting items set as standard are displayed from black to white, and the setting items set by the user are displayed from white to black. The user sees this display and confirms how the copier settings have been changed, that is, the user settings.

  The message display unit 205 displays a message notifying the user of settings of the copying machine status, such as whether copying is possible or whether paper supply is necessary, the number of copies, the copying magnification, and the size of the selected paper. .

  The operation keys 203 include a numeric keypad 206, a start key 207, and a clear key 208. The numeric keypad 206 can be used to designate the number of copies and set a copy magnification. When the user makes these settings (that is, user settings), for example, a message such as “You can copy (with settings)” is displayed on the display unit 205 to notify that the settings have been made by the user. A start key 207 is used to instruct the start of copying. The user operates the clear key 208 when canceling the setting made by the user. Since whether or not the machine accepts the setting by the user can be determined by the above-described message, the clear key 208 may be operated if the setting becomes unnecessary. Thereby, the setting of the copying machine returns from the user setting input by the user to the standard setting.

  Further, in this embodiment, even when the user does not manually cancel the user setting, there is an auto clear means for automatically canceling the user setting. If no operation is performed after a certain period of time has elapsed since the setting by the user, the user setting is canceled and the copying machine setting is returned to the standard setting and initialized. With this auto-clearing means, it is not necessary to cancel the user settings entered by the user every time, and it is avoided that other users unintentionally copy with settings other than the standard settings.

  However, user settings may be automatically cleared against the user's intention. For example, this corresponds to a case where the user takes time for setting and the auto-clearing means is executed before the user setting is completed.

  Therefore, the operation key 203 of the present embodiment includes an auto clear cancel key 209 for returning the setting of the apparatus to the user setting before execution of the auto clear means. By operating the auto clear cancel key 209, even if the auto clear means is executed against the user's intention, the setting of the copier is returned to the user setting before the auto clear means is executed. Thereby, the setting can be resumed from the continuation of the user setting that has been performed halfway.

  FIG. 3 is a schematic configuration diagram of control system hardware in the copying machine. The control circuit 301 of the main body of the copying machine 100 receives the above settings and instructions and operates the copying machine. The control circuit 301 is connected to each circuit such as the operation panel circuit 302 and the sheet feeding device.

  The control circuit 301 includes a CPU (Central Processing Unit) 303 and a bus 304. A ROM (Read Only Memory) 305 and a RAM (Random Access Memory) 306 are connected to the bus 304. The ROM 305 stores control programs, standard settings, and other data. The CPU 303 reads out and executes the control program in the ROM 305, and the control program controls the operation of each drive unit by exchanging data and commands with a driver corresponding to each drive unit, which is also stored in the ROM 305. . The RAM 306 is used as a work area for the CPU 303 or used for storing temporary data (for example, user setting data).

  An internal interface 309 is also connected to the bus 304 of the control circuit 301. The internal interface 309 connects the operation panel circuit 302 and other circuits to the control circuit 301. The CPU 303 receives a signal from a circuit such as an operation panel through the internal interface 309 or transmits a signal to a circuit such as the operation panel.

  The operation panel circuit 302 includes a CPU 312, a touch panel 313, a display 202, operation keys 203, and an internal interface 314 on a bus 311. When the user operates the operation key 203 or the touch panel 313, the CPU 325 transmits a signal based on the operation to the control circuit 301 through the internal interface 314. For example, when the user sets the density and copy magnification using the operation keys 203 and the touch panel 313, the setting contents are sent to the control circuit 301. The control circuit 301 controls the image forming unit according to the setting contents.

  Next, a processing procedure when the auto clear function is executed will be described with reference to FIGS. FIG. 4 is a functional block diagram of the copying machine according to the present embodiment. FIG. 5 is a flowchart showing a processing procedure when the auto-clear function is executed.

  It is assumed that the user has changed some of the standard setting items and set the desired user settings again. At this time, the setting accepting unit of the copying machine is in a state of accepting a setting input by the user (S1).

  When the user setting is made, the display 202 displays the user setting items changed from the standard setting by the display means 404, for example, the setting items such as the number of copies, the copy magnification, and the selected paper size (S2). . With this display, the user confirms which setting item has been changed from the standard setting.

  If there is no next setting input even after a predetermined time has elapsed from a certain setting input (S3), the setting contents of the user setting made by the user are stored in the storage means 403 (S4). A storage unit 403 includes the RAM 306, the ROM 305, and the like, and temporarily stores the user settings. As will be described later, in addition to user settings, settings of standard settings and control programs such as an auto-clear program and an auto-clear release program described later are also stored.

  When the setting contents of the user setting are stored in the storage unit 403, the auto clear unit 401 is executed (S5, S6). The auto-clearing unit 401 resets the setting of the copying machine to a predetermined standard setting after a predetermined time has elapsed without any user operation. More specifically, the auto-clear program stored in the storage unit 403 reads the standard setting content stored in the storage unit 403 (S5), and the copier setting is initialized from the user setting to the standard setting. (S6).

  When the auto-clearing means is executed, standard setting items are displayed on the display 202 by the display means 404 (S7). By this display, the user can know that the setting of the copier has been reset to the standard setting.

  The above is the processing procedure when the auto-clearing means is executed.

However, the auto-clearing means may be executed against the user's intention. Specifically, for example, when the user clears the user setting and the auto-clearing means is executed when all the settings are not completed, or the user must leave the copier during the user setting, For example, when the means is executed. In preparation for such a case, the copying machine of the present embodiment has an auto-clear cancel function that cancels the auto-clear function after the auto-clear means is executed.
Next, a processing procedure when the auto clear function is canceled will be described with reference to FIGS. 4, 6, and 7. FIG. 6 is a flowchart showing a processing procedure when the auto-clear function is canceled. FIG. 7 shows an overview of the display when the auto-clear function in this embodiment is released.

  As described above, when the auto clear means is executed against the user's intention, the user presses the auto clear cancel key 209.

  When the key input of the auto clear cancel key 209 is accepted (S11), the auto clear is canceled by the auto clear cancel means 402. After the auto-clearing unit is executed, the auto-clear canceling unit 402 returns the setting of the copier from the standard setting to the user setting before the auto-clearing unit is executed based on the operation of the user's auto-clear canceling key 209. Specifically, the auto clear cancellation program stored in the storage unit 403 reads the setting contents of the user setting stored in the storage unit 403 (S12), so that the copier setting is changed from the standard setting to the user setting. (S13). As a result, even if the auto-clearing means is executed against the user's intention, the user does not have to reset the user setting to the desired user setting from the beginning. You can resume.

  When the auto-clearing means is released, the setting items of the user settings before the auto-clearing are displayed on the display 202 by the display means 404 (S14).

  Here, if the user setting has not been completed before the auto-clearing means is executed, the user setting is continued. However, since the standard setting is once restored by the auto-clearing means 401, the user setting may not be clearly stored until the auto-clearing is executed. In such a case, it is impossible to determine where the setting should be resumed, and eventually all setting items to be changed from the standard setting must be confirmed.

  In view of this, the display unit 404 according to the present embodiment displays the user setting item before the auto-clearing unit is executed when the device setting is returned to the user setting by the auto-clear releasing unit 402. It is displayed in a format different from the item (that is, the setting item not changed to the user setting) (S15). The different formats are not particularly limited as long as the user setting items changed by the user and the standard setting items can be clearly distinguished. In the present embodiment, the user setting item and the standard setting item before the auto-clearing means are executed are displayed in different colors. For example, in FIG. 7, the user changes “density setting” to “light”, “output condition” to “punching”, and “aggregation setting” to “2 in 1”. In this case, “light”, “punching”, and “2 in 1” 701 of the user setting are displayed in red, for example. On the other hand, the setting items of “Magnification setting”, “Paper type selection”, and “Double-sided setting” remain the standard settings (“Magnification setting” is “Normal size”, “Paper type selection” is “Plain paper”, “Double-sided” “Setting” is “one side → one side”). In this case, the standard setting “same size” “plain paper” “single side → single side” 702 is displayed in black, for example.

  As described above, by displaying in different formats, it becomes clear which setting item the user changed before the auto-clearing means is executed, and when setting change is added, which setting item is changed It becomes easy to judge.

  The present invention can also be applied to an image forming apparatus other than a digital copying machine, such as a printer, a facsimile machine, or a multifunction machine. For example, when the present invention is applied to a multifunction machine, control may be performed so that the auto-reclear function is canceled for each of various functions such as a scanner function, a print function, and a facsimile function that the multifunction machine has.

  The auto-clear program and the auto-clear cancellation program as described above can be provided to a third party using a computer-readable medium. For example, a program command is expressed by an electric signal, an optical signal, a magnetic signal, etc., and the signal is placed on a carrier wave and transmitted, so that the program is provided on a transmission medium such as a coaxial cable, copper wire, or optical fiber Can do. The control program described above may be recorded on a computer-readable recording medium. Computer-readable recording media include optical media such as CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-RAM, DVD-R, and DVD-RW, magnetic media such as flexible disks, A semiconductor memory such as a flash memory or a RAM can be used.

  The embodiments described above do not limit the technical scope of the present invention, and various modifications and applications other than those already described are possible within the scope of the present invention.

  In the above-described embodiment, the user setting item and the standard setting item are displayed with different colors. However, the present invention is not limited to this. For example, user-set setting items before execution of auto-clearing means may be displayed with broken lines, and standard-setting setting items may be displayed with solid lines. Further, only setting items of user settings may be displayed in a blinking manner.

  The image forming apparatus according to the present invention is useful for various apparatuses such as a copying machine, a printer, a facsimile machine, and a multifunction machine.
