コピー、プリンタ、FAX等の複合機能を有する画像形成装置には記録紙を給紙するための給紙トレイを複数備えているものがある。複数の給紙トレイを備えている機種においては、大量の原稿を排紙する可能性があるのでフィニッシャ等の排紙トレイを複数備えているものが多い(例えば特許文献1参照)。
特開2002−326731公報
Some image forming apparatuses having a composite function such as a copy, a printer, and a FAX have a plurality of paper feed trays for feeding recording paper. Many models having a plurality of paper feed trays are likely to have a plurality of paper discharge trays such as finishers because a large amount of documents may be discharged (see, for example, Patent Document 1).
JP 2002-326731 A

読み取られた画像データは画像メモリに格納され、画像形成部における画像形成動作の開始と共に感光体上に画像データが光情報として照射されて静電潜像が形成され、静電潜像の現像によるトナー像化、トナー像の記録紙上への転写が行われる。記録紙は両面とも白紙のものが一般的であるが、片面に既に画像データが転写されているものもある。前者は両面とも使用可能なのでユーザーにより両面書き込み等の転写に関する設定が行える。
しかし後者の場合、事前に片面が書き込まれていることをユーザーが既知のものとしていないと、知らずに両面書き込み等の設定を行ってしまい、2度書きをしてユーザーが意図しない記録紙を排出してしまうことになる。
同じ給紙トレイに片面、両面書き込み可能な記録紙が混在している場合もトレイに入っているどの記録紙が片面、両面なのか簡単に分別するのは難しい。分別のための作業も必要となり極めて非効率的である。
本発明は、記録紙の状態(両面白紙、片面白紙、両面書き込み済み)を迅速に把握し、効率のよい画像形成(複写)を行うことができる画像形成装置を提供することを目的とする。
The read image data is stored in the image memory, and at the start of the image forming operation in the image forming unit, the image data is irradiated as light information on the photoconductor to form an electrostatic latent image, and the electrostatic latent image is developed. A toner image is formed and the toner image is transferred onto a recording sheet. The recording paper is generally white on both sides, but there are also some on which image data has already been transferred on one side. Since the former can be used on both sides, the user can make settings for transfer such as double-sided writing.
However, in the latter case, if the user does not know that one side has been written in advance, double-sided writing etc. will be set without knowing it, and the recording paper unintended by the user will be discharged after writing twice Will end up.
Even in the case where recording sheets capable of writing on one side or both sides are mixed in the same sheet feeding tray, it is difficult to easily distinguish which recording sheet in the tray is one side or both sides. Work for separation is also required, which is extremely inefficient.
An object of the present invention is to provide an image forming apparatus capable of quickly grasping the state of recording paper (double-sided white paper, single-sided white paper, double-sided written) and performing efficient image formation (copying).

上記目的を達成するために、請求項1記載の発明は、複数の排紙トレイを備えている画像形成装置において、給紙される記録紙の表面及び裏面の状態を読み取る記録紙センサを備え、記録紙を順次給紙、搬送しつつ画像形成動作は行わずに、同一状態の記録紙を同じ排紙トレイに排紙する画像形成装置を最も主要な特徴とする。
請求項2記載の発明は、記録紙情報を表示部に表示する請求項1記載の画像形成装置を主要な特徴とする。
In order to achieve the above object, the invention according to claim 1 is an image forming apparatus including a plurality of paper discharge trays, and includes a recording paper sensor that reads a state of a front surface and a back surface of the recording paper fed. An image forming apparatus that discharges recording sheets in the same state to the same discharge tray without feeding an image while sequentially feeding and conveying the recording sheets is the main feature.
According to a second aspect of the present invention, the image forming apparatus according to the first aspect of the present invention displays the recording paper information on the display unit.

本発明によれば、複数の排紙トレイを備えている画像形成装置において、給紙される記録紙の表面及び裏面の状態を読み取る記録紙センサを備え、記録紙を順次給紙、搬送しつつ画像形成動作は行わずに、同一状態の記録紙を同じ排紙トレイに排紙することで、所期の目的を達成することができる。   According to the present invention, an image forming apparatus including a plurality of paper discharge trays includes a recording paper sensor that reads the state of the front and back surfaces of the recording paper to be fed, and sequentially feeds and conveys the recording paper. The intended purpose can be achieved by discharging the recording paper in the same state to the same paper discharge tray without performing the image forming operation.

本発明は、まず給紙トレイに格納されている一群の記録紙に画像を書き込むことをせずに、順次給紙して排紙されるまでの間に画像読取装置によって両面読み取りを行い、記録紙の状態を記録媒体(メモリ)にその都度記憶させ、その状態に基づき排紙先を変えて排紙することができるようにする。そして排紙終了の際に読み取り結果と排紙情報を表示・通知を行うことができるようにする。
以下、具体的に説明する。図1は本発明の実施の形態に係る画像形成装置(複合機)の外観図、図2は同じく簡略構成図である。
図1に示すように本画像形成装置は、本体1がオプションの給紙ユニット2の上に搭載されている。また後処理装置(フィニッシャ)3が本体1の後段に設けてある。本体1の上部手前面には操作部ユニット4が設けてある。
図2に示すように本画像形成装置において、本体1は、記録紙の通過を検知する記録紙センサ(給紙センサ)11、搬送コロ12、記録紙の両面の状態を読み取るイメージセンサ13a、13bを有した画像読み取り部13、エンジン部14を有する。給紙ユニット2は、多段の給紙トレイ21、各給紙トレイ21に対応した給紙コロ22を有する。後処理装置3は多段の排紙トレイ31を有する。画像形成動作については周知であり、本発明と直接関係ないので説明は省略する。
図3は操作部ユニットのレイアウト図である。操作部ユニット4には、画像形成装置のステータスを示せて、タッチパネルによる操作も行うことが可能な表示部41、ユーザーが各種設定・操作を行えるキー入力部42があり、キー入力部42には、スキャナとは別個に記録紙読み取り用のモード(記録紙モード)キー、どの給紙トレイの記録紙を読み取るかの(給紙トレイ選択)キーがあり、このモードを選択することにより記録紙の読み取りが行える。このキーに関してはキー入力部42に特別に設置する必要はなく、他に各種モード選択を行うキーで兼用することができる。
The present invention does not first write an image on a group of recording paper stored in a paper feed tray, but performs double-sided reading by an image reading device until the paper is sequentially fed and discharged. The paper state is stored in the recording medium (memory) each time, and the paper discharge destination can be changed based on the state so that the paper can be discharged. When the paper discharge is completed, the reading result and the paper discharge information can be displayed / notified.
This will be specifically described below. FIG. 1 is an external view of an image forming apparatus (multifunction machine) according to an embodiment of the present invention, and FIG.
As shown in FIG. 1, in the image forming apparatus, a main body 1 is mounted on an optional paper feeding unit 2. A post-processing device (finisher) 3 is provided in the rear stage of the main body 1. An operation unit 4 is provided on the upper front surface of the main body 1.
As shown in FIG. 2, in the image forming apparatus, the main body 1 includes a recording paper sensor (paper feed sensor) 11 that detects the passage of the recording paper, a conveyance roller 12, and image sensors 13a and 13b that read the states of both sides of the recording paper. The image reading unit 13 and the engine unit 14. The sheet feeding unit 2 includes a multi-stage sheet feeding tray 21 and sheet feeding rollers 22 corresponding to the sheet feeding trays 21. The post-processing device 3 has a multistage discharge tray 31. Since the image forming operation is well known and is not directly related to the present invention, the description thereof is omitted.
FIG. 3 is a layout diagram of the operation unit. The operation unit 4 includes a display unit 41 that can display the status of the image forming apparatus and can be operated by a touch panel, and a key input unit 42 that allows a user to perform various settings and operations. In addition to the scanner, there is a recording paper reading mode (recording paper mode) key and a paper feed tray (reading tray selection) key for reading the recording paper. By selecting this mode, the recording paper Can read. This key does not need to be specially installed in the key input unit 42, and can also be used as a key for selecting various modes.

図4は第1の制御例(スキャナ選択モード)を示すフローチャートである(S1〜S14参照)。S1において、記録紙読み取りモードが選択された場合には、給紙トレイと排紙トレイを選択した上で(S3)、給紙が行われ、記録紙センサ11によって記録紙の通過が検出された後で、第1のイメージセンサ13aによって記録紙の片面が読み取られ、画像種類が判別される(S4、5、6)。記録紙の残りの面についても同様な読取が実施される(S7、9、10)。このように、一群の記録紙の束から給紙コロ22によって記録紙を1枚搬送し、記録紙センサ11で記録紙の通過を検知するごとに何枚目の記録紙かを図示しないカウンタ部へ記録する。記録紙の状態には両面とも白紙の状態、片面のみ白紙の状態、両面とも書き込みがなされている状態の3種類の状態があり、カウンタ部により各記録紙ごとの状態を図示しない記録紙管理部にて管理し、画像読み取り部13を構成するイメージセンサ13a、13bで読み取った記録紙の表裏についての画像データを格納後、カウンタの情報を付加する。
そして記録紙管理部に収められた記録紙の情報をエンジン部14へ転送し、エンジン部14は記録紙情報を記録紙へ書き込む(S11)。この際、原稿画像を記録紙に書き込む画像形成動作を行わない。全記録紙を読み終えると読み取った全枚数、各状態ごとの枚数を操作部ユニット4の表示部41に表示させる。各給紙トレイ21と各排紙トレイ31を操作部ユニット4のキー入力部42によって選択できるものとし、指定した給紙トレイのみまたは全ての給紙トレイの記録紙読み込みを行えるものとする。そして、選択された排紙トレイ上に排紙される(S12、13)。
ステップ11において記録紙に書き込む記録紙情報は、記録紙の画像形成領域外等に書込む管理情報等であり、例えば当該記録紙が片面記録済みである等の情報を記録紙上のオペレータに見やすい位置に書き込むことによって、オペレータが画像形成作業を実施する前に除去すべき記録紙を目視により判別したり、両面記録に適さない記録紙を目視により確認するのに便ならしめるためのものである。通常、記録済みの記録紙の記録面の欄外等の端部にこの記録紙情報を画像形成部によって記録することにより、画像の有無の読取を終了した記録紙束を簡単にめくるだけでどの記録紙が片面記録済み、或いは両面記録済みであるかを確認することが可能となる。
FIG. 4 is a flowchart showing a first control example (scanner selection mode) (see S1 to S14). When the recording paper reading mode is selected in S1, the paper feeding tray and the paper discharging tray are selected (S3), paper feeding is performed, and the recording paper sensor 11 detects the passage of the recording paper. Later, one side of the recording paper is read by the first image sensor 13a to determine the image type (S4, 5, 6). Similar reading is performed on the remaining surface of the recording paper (S7, 9, 10). Thus, each time a recording sheet is conveyed from a group of recording paper bundles by the paper feed roller 22 and the recording sheet sensor 11 detects the passage of the recording sheet, the counter unit (not shown) indicates the number of recording sheets. To record. There are three types of recording paper states: blank on both sides, blank on only one side, and writing on both sides, and a recording paper management unit (not shown) for each recording paper by the counter unit The image data on the front and back of the recording paper read by the image sensors 13a and 13b constituting the image reading unit 13 is stored, and then counter information is added.
The information of the recording paper stored in the recording paper management unit is transferred to the engine unit 14, and the engine unit 14 writes the recording paper information on the recording paper (S11). At this time, the image forming operation for writing the document image on the recording paper is not performed. When all the recording sheets have been read, the total number of sheets read and the number of sheets for each state are displayed on the display unit 41 of the operation unit unit 4. It is assumed that each paper feed tray 21 and each paper discharge tray 31 can be selected by the key input unit 42 of the operation unit unit 4, and the recording paper can be read from only the designated paper feed tray or all of the paper feed trays. Then, the paper is discharged onto the selected paper discharge tray (S12, 13).
The recording paper information to be written on the recording paper in step 11 is management information to be written outside the image forming area of the recording paper, for example, a position on the recording paper where it is easy for the operator to see information such as that the recording paper has been recorded on one side In this case, the operator can visually discriminate the recording paper to be removed before carrying out the image forming operation, and can make it easier for the operator to visually confirm the recording paper that is not suitable for double-sided recording. Normally, by recording this recording paper information on the edge of the recording surface of the recording paper that has already been recorded by the image forming unit, the recording paper bundle that has been read for the presence / absence of an image can be simply flipped to determine which recording It is possible to confirm whether the paper has been recorded on one side or on both sides.

図5は第2の制御例(再読み取りモード)を示すフローチャートである(S21〜S40参照)。S21において、再読み取りモードを選択した場合、一度読み取った記録紙の束を再度給紙トレイ21に給紙し搬送する(セットする)。給紙トレイにセットされた記録紙が再給紙開始され、記録紙センサ11で通過が検出され、画像読み取り部13によって両面の読取りが実施されると(S23、25、26、28〜30、32、33、35)、前回読み取り時の記録情報をメモリから呼び出し、表示部41に表示させる。
S30、S35において、2つのイメージセンサで読み取った際に1つでも画像データに違いを検出した場合は(S30、S35でNo)、直ちにその記録紙の状態を表示部41に表示させ、ユーザーが一目で前回との違いを確認できるようにすると共に記録紙の搬送を中止し(S31)、記録紙の給紙を中止した旨を表示部41に表示させ(S36)、前回の状態を記録した記録紙に前回との相違/中止情報を付け加え排紙する。また再読み込みモードの場合もエンジン部14は記録紙管理部からの制御によって記録紙情報以外のデータの書き込みは行わないものとする。
S25において、排紙先は再読み取りモードでの操作で各記録紙の状態(両面白紙、片面のみ白紙、両面書き込み済み)ごとに設定しておき、各状態に応じて記録紙管理部が指示するものとする。排紙トレイ31は上下動可能なものであり、記録紙管理部の制御指示に基づき、記録紙ごとに排紙トレイ31を上下に移動させて記録紙ごとのソートを行う。検出したデータに違いがない場合はそのまま指定した排紙トレイ31に排紙する。排紙完了と同時に正常に終わったことを伝える旨を表示部41に表示し、前回の状態を記録した記録紙に正常終了したステータスを書き込み排紙する。
なお、この再読み取りモードは、記録済みの用紙の有無を一度確認しただけでは、不安な場合に再度確認するためのモードである。
本発明により記録紙の分別を一度で大量にかつ時間を無駄にすることなく効率的に行うことができる。さらに表示部に分別ごとの枚数を表示させることによりユーザーの必要とする枚数にするのにどれ位足りないかなど複数回で記録紙読み取りを行う際に確認を容易に行うことができる。
FIG. 5 is a flowchart showing a second control example (reread mode) (see S21 to S40). If the re-read mode is selected in S21, a bundle of recording papers once read is again fed to the paper feed tray 21 and conveyed (set). When the recording paper set in the paper feed tray is started to be fed again, the recording paper sensor 11 detects the passage, and the image reading unit 13 reads both sides (S23, 25, 26, 28-30, 32, 33, 35), the recording information at the time of the previous reading is retrieved from the memory and displayed on the display unit 41.
In S30 and S35, if even one image data is detected when read by two image sensors (No in S30 and S35), the state of the recording paper is immediately displayed on the display unit 41, and the user The difference from the previous time can be confirmed at a glance, the conveyance of the recording paper is stopped (S31), the fact that the recording paper feeding is stopped is displayed on the display unit 41 (S36), and the previous state is recorded. The paper is discharged after adding the difference / stop information from the previous time to the recording paper. In the reread mode, the engine unit 14 does not write data other than the recording sheet information under the control of the recording sheet management unit.
In S25, the paper discharge destination is set for each recording paper state (double-sided white paper, single-sided white paper, double-sided written) by the operation in the re-reading mode, and the recording paper management unit instructs according to each state. Shall. The paper discharge tray 31 can be moved up and down, and based on a control instruction from the recording paper management unit, the paper discharge tray 31 is moved up and down for each recording paper to sort the recording paper. If there is no difference in the detected data, the paper is discharged as it is to the designated paper discharge tray 31. At the same time as the completion of paper discharge, a message indicating that the process has been completed normally is displayed on the display unit 41, and the status of normal completion is written and discharged on the recording paper on which the previous state was recorded.
This re-reading mode is a mode for reconfirming when there is anxiety by once confirming the presence or absence of a recorded sheet.
According to the present invention, it is possible to efficiently perform the sorting of the recording paper at once without waste of time. Further, by displaying the number of sheets for each classification on the display unit, it is possible to easily check when the recording paper is read a plurality of times, such as how much is not enough for the user.
