制御部１は、演算装置であるＣＰＵ（Central Processing Unit）と、記憶装置であるＲＯＭ（Read Only Memory）及びＲＡＭ（Random Access Memory）を有し、ＣＰＵがＲＯＭに記憶されているＯＳを実行することによって画像形成装置１０の各部を制御する。制御部１は、通信Ｉ／Ｆ（Interface）を有し、ＬＡＮ（Local Area Network）を介して他の装置からデータを受信する。制御部１は、受信したデータをビットマップ形式の画像データに変換して書込部１３に出力する。   The control unit 1 includes a central processing unit (CPU) that is an arithmetic device, a read only memory (ROM) and a random access memory (RAM) that are storage devices, and the CPU executes an OS stored in the ROM. Thus, each part of the image forming apparatus 10 is controlled. The control unit 1 has a communication I / F (Interface), and receives data from other devices via a LAN (Local Area Network). The control unit 1 converts the received data into bitmap format image data and outputs the image data to the writing unit 13.

媒体容器３０（本発明に係る容器の一例）には、紙等、シート状の記録媒体Ｐが積み重ねられて収容されている。第１ローラ３１、第２ローラ３２は、画像形成装置１０の本体側に設けられており、第３ローラ３３は、媒体容器３０に設けられている。第１ローラ３１は、最も上に位置する記録媒体Ｐに接触し、矢印Ｃの方向に回転することによって当該記録媒体Ｐを媒体容器３０から送り出す。第２ローラ３２と第３ローラ３３は、第１ローラと同じ方向に回転する。第３ローラ３３にはトルクリミッタが設けられており、記録媒体Ｐが重ならずに送り出された場合には、当該記録媒体Ｐとの摩擦により第３ローラ３３が逆方向に回転させられ、当該記録媒体Ｐが搬送路３４に送り出される。搬送路３４に送り出された記録媒体Ｐは、搬送ローラによって矢印Ｂの方向に搬送される。複数の記録媒体Ｐが重なって送り出された場合には、最も上に位置する記録媒体Ｐ以外の記録媒体Ｐが第３ローラ３３によって媒体容器３０に押し戻される。   In the medium container 30 (an example of the container according to the present invention), sheet-like recording media P such as paper are stacked and accommodated.

When the recording medium P is sent out without overlapping, the third roller 33 is rotated in the reverse direction by friction with the recording medium P, and The recording medium P is sent out to the conveyance path 34. The recording medium P sent out to the conveyance path 34 is conveyed in the direction of arrow B by the conveyance roller. When a plurality of recording media P are sent out in an overlapping manner, the recording media P other than the recording medium P positioned at the top are pushed back to the medium container 30 by the third roller 33.

感光体１１の周囲には、帯電部１２、書込部１３、現像部１４、転写部１５が設けられている。
感光体１１は、モータ等の駆動手段（図示省略）により矢印Ａの方向に回転駆動される回転体であり、その外周面には、光の照射によって電位が変化する半導体で作製された感光層が設けられている。
帯電部１２は、例えば、コロトロン型帯電装置、ローラ式帯電装置等であり、感光体１１の表面を予め定められた電位に帯電させる。 Around the photoconductor 11, a charging unit 12, a writing unit 13, a developing unit 14, and a transfer unit 15 are provided.
The photosensitive member 11 is a rotating member that is rotationally driven in the direction of an arrow A by a driving means (not shown) such as a motor, and a photosensitive layer made of a semiconductor whose potential is changed by light irradiation on the outer peripheral surface thereof. Is provided.
The charging unit 12 is, for example, a corotron type charging device, a roller type charging device or the like, and charges the surface of the photoconductor 11 to a predetermined potential.

書込部１３は、画像データに基づいて感光体１１に潜像を書き込む。具体的には、書込部１３は、制御部１から供給された画像データで表される各画素の階調に対応するレーザビームＬＢを生成し、このレーザビームＬＢで感光体１１の表面を感光体１１の軸方向（主走査方向）に走査することによって潜像を形成する。感光体１１が回転駆動されることによって主走査方向の走査線単位での潜像の書き込みが感光体１１の周方向（副走査方向）に繰り返される。   The writing unit 13 writes a latent image on the photoconductor 11 based on the image data. Specifically, the writing unit 13 generates a laser beam LB corresponding to the gradation of each pixel represented by the image data supplied from the control unit 1, and the surface of the photoconductor 11 is scanned with the laser beam LB. A latent image is formed by scanning in the axial direction (main scanning direction) of the photoconductor 11. As the photoconductor 11 is driven to rotate, writing of latent images in units of scanning lines in the main scanning direction is repeated in the circumferential direction (sub-scanning direction) of the photoconductor 11.

現像部１４は、感光体１１に書き込まれた潜像を現像する。具体的には、現像部１４の内部には、トナーとキャリアからなる２成分現像剤が収容されている。トナーは、樹脂製の粉体を黒色の色材で着色したものである。キャリアは、磁性体で作製された粉体である。現像部１４の筐体は、感光体１１に対向する側が開口しており、その内部には、感光体１１と互いの外周面が対向するように現像ローラが設けられている。２成分現像剤は、回転駆動される現像ローラの外周面に付着する。現像ローラには、潜像と逆極性の現像バイアス電圧が印加され、この現像バイアス電圧によってトナーが帯電させられる結果、静電引力によりトナーが潜像上に移送される。このようにして潜像がトナーで現像され、感光体１１にトナー像が形成される。   The developing unit 14 develops the latent image written on the photoconductor 11. Specifically, a two-component developer composed of toner and carrier is accommodated in the developing unit 14. The toner is obtained by coloring resin powder with a black color material. The carrier is a powder made of a magnetic material. The housing of the developing unit 14 has an opening on the side facing the photoconductor 11, and a developing roller is provided inside the housing so that the outer circumferential surface of the photoconductor 11 faces each other. The two-component developer adheres to the outer peripheral surface of the rotationally driven developing roller. A developing bias voltage having a polarity opposite to that of the latent image is applied to the developing roller, and the toner is charged by the developing bias voltage. As a result, the toner is transferred onto the latent image by electrostatic attraction. In this way, the latent image is developed with toner, and a toner image is formed on the photoreceptor 11.

転写部１５は、例えば、コロトロン型帯電装置、ローラ式帯電装置等であり、搬送路３４を挟んで感光体１１と対向する位置に設けられている。転写部１５には、感光体１１上のトナー像と逆極性の転写バイアス電圧が印加され、この転写バイアス電圧によって記録媒体Ｐが帯電させられる結果、静電引力によりトナー像が記録媒体Ｐに転写される。   The transfer unit 15 is, for example, a corotron charging device, a roller charging device, or the like, and is provided at a position facing the photoconductor 11 with the conveyance path 34 interposed therebetween. A transfer bias voltage having a polarity opposite to that of the toner image on the photoconductor 11 is applied to the transfer unit 15, and the recording medium P is charged by the transfer bias voltage. As a result, the toner image is transferred to the recording medium P by electrostatic attraction. Is done.

定着部１６は、熱源を有する加熱部材と、加熱部材に押し当てられる加圧部材とを有し、加熱部材と加圧部材との間に媒体Ｐを挟んでトナー像を溶融・加圧することによって、トナー像を記録媒体Ｐに定着させる。
排出部３６は、筐体２０の上面において搬送路３４の出口に設けられた、記録媒体Ｐが収まる大きさを有する窪みである。定着部１６によってトナー像が定着された記録媒体Ｐが、搬送路３４の出口から排出部３６に排出される。 The fixing unit 16 includes a heating member having a heat source and a pressure member pressed against the heating member, and melts and presses the toner image by sandwiching the medium P between the heating member and the pressure member. The toner image is fixed on the recording medium P.
The discharge unit 36 is a recess provided at the exit of the conveyance path 34 on the upper surface of the housing 20 and having a size to accommodate the recording medium P. The recording medium P on which the toner image is fixed by the fixing unit 16 is discharged from the exit of the conveyance path 34 to the discharge unit 36.

As shown in FIGS. 3 and 6, the edge 2151 of the bottom plate member 215 is raised on the opposite side of the engaging portions 171 and 172 across the rotating member 272, and the end of the rotating means 274 is the edge. By being abutted against 2151, the rotating member 272 is rotated in a direction in which the convex portion 273 is engaged with the engaging portion 171.

一方、回転部材２７２の回転軸２７１と第２壁部２２０との間の位置には柱状部２７５が設けられている。柱状部２７５は、回転部材２７２からＺ方向に立ち上げられており、内部は中空である。把手２７６は、柱状部２７５からＸ方向に突き出すように設けられている。把手２７６の第１壁部１２０側の面を指等で押すことにより、回転部材２７２が回転手段２７４による回転と反対方向に回転させられ、凸部２７３と噛合部１７１及び１７２との噛み合いが解かれる（図７参照）。

The columnar portion 275 is raised from the rotating member 272 in the Z direction, and the inside is hollow. The handle 276 is provided so as to protrude from the columnar portion 275 in the X direction. By pushing the surface on the first wall 120 side of the handle 276 with a finger or the like, the rotating member 272 is rotated in the direction opposite to the rotation by the rotating means 274, and the meshing between the convex portion 273 and the meshing portions 171 and 172 is released. (See FIG. 7).
The rotating member 272, the convex portion 273, the rotating means 274, the columnar portion 275, and the handle 276 are integrally formed of resin.

図６は、第２収容部２００が第１収容部１００に最も奥まで押し込まれた状態を示し、この場合に、凸部２７３が噛合部１７１に噛み合わされる。この状態における第１壁部１２０と規制部材２５１との距離は、例えば、Ａ４サイズの紙の長手方向の長さ（297mm）となる。
図７に示すように回転部材２７２を回転させて凸部２７３と噛合部１７１との噛み合いが解かれると、第２収容部２００が第１収容部１００から自由に引き出される状態となる。第２収容部２００を第１収容部１００から引き出して凸部２７３を噛合部１７２に噛み合わせた場合、第１壁部１２０と規制部材２５１との距離は、例えば、リーガルサイズの紙の長手方向の長さ（356mm）となる。 FIG. 6 shows a state in which the second housing part 200 is pushed all the way into the first housing part 100, and in this case, the convex part 273 is meshed with the meshing part 171. The distance between the first wall 120 and the regulating member 251 in this state is, for example, the length (297 mm) in the longitudinal direction of A4 size paper.
As shown in FIG. 7, when the rotating member 272 is rotated and the meshing between the convex portion 273 and the meshing portion 171 is released, the second housing portion 200 is freely pulled out from the first housing portion 100. When the second storage unit 200 is pulled out from the first storage unit 100 and the convex part 273 is engaged with the engagement part 172, the distance between the first wall part 120 and the regulating member 251 is, for example, the longitudinal direction of legal-size paper The length (356mm).

第２壁部２２０の柱状部２７５側の面には、回転手段２７４による回転と反対方向に回転部材２７２が回転させられた場合に柱状部２７５の第２壁部２２０に対向する部位に接触する接触部２２１が設けられている。図３に示すように、接触部２２１は、柱状部２７５の長手方向に延びるリブである。また、接触部２２１は、回転手段２７４による回転と反対方向に回転部材２７２が回転させられた場合の柱状部２７５の側面の軌跡に対応する位置まで第２壁部２２０から突き出ていることが望ましい。   The surface of the second wall 220 on the side of the columnar portion 275 comes into contact with the portion of the columnar portion 275 that faces the second wall 220 when the rotating member 272 is rotated in the direction opposite to the rotation by the rotating means 274. A contact portion 221 is provided. As shown in FIG. 3, the contact portion 221 is a rib extending in the longitudinal direction of the columnar portion 275. Further, it is desirable that the contact part 221 protrudes from the second wall part 220 to a position corresponding to the locus of the side surface of the columnar part 275 when the rotation member 272 is rotated in the direction opposite to the rotation by the rotation means 274. .

本実施形態の作用は次のとおりである。
把手２７６の第１壁部１２０側の面をユーザが指で押す操作を想定する。この場合、把手２７６を押す力の方向（図６では、−Ｘ方向）と、この力が加わる点と回転軸２７１とを結ぶ線分とが交差するため、回転手段２７４による回転と反対方向の回転が回転部材２７２に生じる。ここで、一体化された把手２７６、柱状部２７５及び回転部材２７２は剛体ではないため、これらに変形が生じることになる。この変形には、柱状部２７５の捩れや撓みが含まれ、この変形が大きいほど、回転部材２７２の回転が小さくなる。すると、凸部２７３と噛合部１７１又は１７２との噛み合いを解くのに必要な回転部材２７２の回転が得られないという事態が起こり得る。このような柱状部２７５の変形を抑制するためには、柱状部２７５を金属などの比較的剛性の高い材料で作製することや、柱状部２７５の断面を太くすることなどが考えられるが、その場合、コストが高くなってしまう。一方、コスト低減のためには、本実施形態のように、柱状部２７５を樹脂で形成する構成や、柱状部２７５を中空構造とする構成が有利であるが、このような構成は、柱状部２７５の変形の抑制には不利に働く。また、媒体容器３０を大容量化する場合、媒体容器３０の深さを深くすることが必要になるが、その場合、柱状部２７５が短いままだとユーザの指が把手２７６に届きにくくなるので、媒体容器３０を深くすればするほど柱状部２７５も長くすることが必要になり、余計に柱状部２７５が変形しやすくなる。 The operation of this embodiment is as follows.
Assume that the user presses the surface of the handle 276 on the first wall 120 side with a finger. In this case, the direction of the force pushing the handle 276 (in the −X direction in FIG. 6) intersects the line connecting the point where the force is applied and the rotation shaft 271. Rotation occurs on the rotating member 272. Here, since the integrated handle 276, the columnar portion 275, and the rotating member 272 are not rigid bodies, they are deformed. This deformation includes twisting and bending of the columnar portion 275, and the larger the deformation, the smaller the rotation of the rotating member 272. Then, a situation may occur in which the rotation of the rotating member 272 necessary for releasing the meshing between the convex portion 273 and the meshing portion 171 or 172 cannot be obtained. In order to suppress such deformation of the columnar portion 275, it is conceivable to make the columnar portion 275 from a material having a relatively high rigidity such as metal, or to increase the cross section of the columnar portion 275. In this case, the cost becomes high. On the other hand, in order to reduce costs, a configuration in which the columnar portion 275 is formed of a resin as in the present embodiment and a configuration in which the columnar portion 275 is a hollow structure are advantageous. This is disadvantageous in suppressing the deformation of 275. Further, when the capacity of the medium container 30 is increased, it is necessary to increase the depth of the medium container 30. In this case, if the columnar portion 275 is kept short, the user's finger is difficult to reach the handle 276. The deeper the medium container 30 is, the longer the columnar portion 275 needs to be lengthened, and the columnar portion 275 becomes more easily deformed.

本実施形態では、第２壁部２２０に接触部２２１が設けられているので、回転手段２７４による回転と反対方向に回転部材２７２を回転させる力が柱状部２７５に働いた場合に柱状部２７５の第２壁部２２０に対向する部位に接触部２２１が接触する。従って、接触部２２１を有しない構成と比べて、柱状部２７５の変形が抑制され、凸部２７３と噛合部１７１又は１７２との噛み合いを解くのに必要な回転部材２７２の回転が得られないという事態が生じにくくなる。
また、本実施形態によれば、回転部材２７２が回転させられた場合の柱状部２７５の側面の軌跡に対応する位置まで接触部２２１が突き出ていない構成と比べて、柱状部２７５の変形が抑制される。
また、本実施形態によれば、接触部２２１が柱状部の長手方向に延びるリブでない構成と比べて、柱状部２２１の変形が抑制される。
また、本実施形態によれば、接触部を有しない構成と比べて、互いにサイズの異なる複数種類の記録媒体を使い分ける場合に、媒体容器３０を伸縮させる作業が容易になる。 In this embodiment, since the contact part 221 is provided in the 2nd wall part 220, when the force which rotates the rotation member 272 to the direction opposite to the rotation by the rotation means 274 acted on the columnar part 275, The contact part 221 contacts the part facing the second wall part 220. Therefore, as compared with the configuration without the contact portion 221, the deformation of the columnar portion 275 is suppressed, and the rotation of the rotating member 272 necessary for releasing the engagement between the convex portion 273 and the engagement portion 171 or 172 cannot be obtained. Things are less likely to occur.
Further, according to the present embodiment, the deformation of the columnar portion 275 is suppressed as compared with the configuration in which the contact portion 221 does not protrude to the position corresponding to the locus of the side surface of the columnar portion 275 when the rotating member 272 is rotated. Is done.
Further, according to the present embodiment, the deformation of the columnar portion 221 is suppressed as compared with the configuration in which the contact portion 221 is not a rib extending in the longitudinal direction of the columnar portion.
In addition, according to the present embodiment, the operation of expanding and contracting the medium container 30 is facilitated when a plurality of types of recording media having different sizes are used properly as compared with a configuration without a contact portion.
