Description

本発明は、画像形成装置に関する。   The present invention relates to an image forming apparatus.

従来、装置本体に内蔵される給紙カセットとは別に、手差し用の給紙口を備えた画像形成装置は既に提案されている(例えば、特許文献1参照。)。この画像形成装置の場合、手差し用給紙口はプリンタ装置の正面(前面)に設けられ、その手差し用給紙口には、給紙口下端側にある水平な軸線を回転中心にして開閉可能なトレイ(特許文献1:図1〜図10中の符号(30)参照。)が設けられている。   2. Description of the Related Art Conventionally, an image forming apparatus provided with a manual paper feeding port separately from a paper feeding cassette built in the apparatus main body has already been proposed (see, for example, Patent Document 1). In the case of this image forming apparatus, the manual paper feed port is provided on the front surface (front surface) of the printer device, and the manual paper feed port can be opened and closed with a horizontal axis at the lower end of the paper feed port as a rotation center. A tray (see Patent Document 1: reference numeral (30) in FIGS. 1 to 10) is provided.

このようなトレイを利用すれば、手差し用給紙口を使用して給紙を行う際に、トレイで被記録媒体の背面を支持することができるので、このようなトレイが設けられていない場合に比べ、被記録媒体を装置内へスムーズに導入することができる。   If such a tray is used, the back of the recording medium can be supported by the tray when the paper is fed using the manual paper feed port, and thus such a tray is not provided. As compared with the above, the recording medium can be smoothly introduced into the apparatus.

特開2008−297054号公報JP 2008-297054 A

しかしながら、上記特許文献1に記載のトレイは、給紙口(開口)を塞ぐカバーとしての役割も兼ね備えていることから、トレイとして機能させる場合、その被記録媒体搬送方向の長さを、給紙口の高さ方向寸法と同程度にせざるを得ず、さらに長くすることは難しい。   However, since the tray described in Patent Document 1 also serves as a cover for closing the paper feed opening (opening), when functioning as a tray, the length in the recording medium conveyance direction is set to It must be the same as the height dimension of the mouth, and it is difficult to make it longer.

そのため、このようなトレイでは、被記録媒体の側端を搬送方向へと案内するガイドとして機能させようとしても、案内可能な距離を十分に長くすることができないので、被記録媒体の斜行を精度良く矯正することは困難であった。   Therefore, in such a tray, even if an attempt is made to function as a guide for guiding the side edge of the recording medium in the transport direction, the guideable distance cannot be made sufficiently long. It was difficult to correct accurately.

本発明は、上記問題を解決するためになされたものであり、その目的は、閉じたときには手差し用給紙口を塞ぐカバーとして機能する一方、開いたときには従来よりも長距離にわたって被記録媒体を手差し用給紙口に対する搬送方向へ案内可能なカバー部材を備えた画像形成装置を提供することにある。   The present invention has been made in order to solve the above-described problems. The object of the present invention is to function as a cover that closes the manual paper feed port when the cover is closed. An object of the present invention is to provide an image forming apparatus including a cover member capable of guiding in a conveyance direction with respect to a manual paper feed port.

以下、本発明において採用した構成について説明する。
本発明の画像形成装置は、被記録媒体に対して画像を形成する画像形成手段と、手差し用給紙口に差し込まれた被記録媒体を、前記手差し用給紙口から前記画像形成手段へと搬送する際に利用される搬送経路と、開閉可能な構造になっていて、閉じられた際には前記手差し用給紙口を覆うカバー部材とを備えており、前記カバー部材は、一方向についての寸法が、前記一方向に直交する方向の寸法よりも長い部材からなり、閉じられた際には、前記手差し用給紙口に沿って延びる方向と前記一方向が一致する位置へと移動することで、前記手差し用給紙口を覆う状態になる一方、開かれた際には、前記手差し用給紙口への被記録媒体の差し込み方向と前記一方向が一致する位置へと移動することで、前記一方向に沿って前記被記録媒体を前記手差し用給紙口へと案内可能なガイド部として機能する状態になることを特徴とする。
Hereinafter, the configuration employed in the present invention will be described.
An image forming apparatus according to the present invention includes: an image forming unit that forms an image on a recording medium; and a recording medium that is inserted into a manual feeding port from the manual feeding port to the image forming unit. A transport path used when transporting, and a cover member that is openable and closable and covers the manual feed port when closed, the cover member being in one direction Is formed of a member longer than the dimension in the direction orthogonal to the one direction, and when closed, it moves to a position where the one direction and the direction extending along the manual feed port coincide with each other. As a result, the manual feed port is covered, and when it is opened, the recording medium is inserted into the manual feed port and moved to a position where the one direction coincides with the insertion direction. Then, the recording medium is moved along the one direction. Characterized in that a state which serves as a guide capable of guiding portions to insert paper feed mouth.

このように構成された画像形成装置によれば、手差し用給紙口を覆うカバー部材を開くことにより、被記録媒体を手差し用給紙口へと案内するガイド部として利用することができる。しかも、カバー部材を開いた際には、カバー部材の長手方向が被記録媒体の差し込み方向と一致するので、被記録媒体を案内可能な距離を十分に確保できる。   According to the image forming apparatus configured as described above, the recording medium can be used as a guide unit that guides the recording medium to the manual feed port by opening the cover member that covers the manual feed port. In addition, when the cover member is opened, the longitudinal direction of the cover member coincides with the insertion direction of the recording medium, so that a sufficient distance for guiding the recording medium can be secured.

したがって、被記録媒体の斜行を防止または抑制することができ、ひいては被記録媒体の斜行に起因する紙詰まりの発生や被記録媒体における皺の発生などを抑制できる。また、利用者が手差し用給紙口からの給紙作業を行う際に、ガイド部により被記録媒体を真っ直ぐに差し込むことが容易になるので、被記録媒体を案内可能な距離が短い場合に比べ、差し込み方向の微妙な調整が不要となり、給紙作業をスムーズに実施することができる。   Therefore, it is possible to prevent or suppress the skew of the recording medium, and it is possible to suppress the occurrence of a paper jam caused by the skew of the recording medium and the occurrence of wrinkles on the recording medium. In addition, when the user performs the paper feeding operation from the manual paper feeding port, it becomes easy to insert the recording medium straight by the guide portion, so that the distance that can guide the recording medium is short compared to the case where the recording medium can be guided. Subtle adjustment of the insertion direction is unnecessary, and the paper feeding operation can be performed smoothly.

ところで、本発明の画像形成装置において、前記カバー部材は、閉じられた際に前記手差し用給紙口の一部を覆う第一カバー部材と、閉じられた際に前記手差し用給紙口の残りの一部を覆う第二カバー部材によって構成されていて、開かれた際には、前記被記録媒体の両端のうち、いずれか一方の端部に前記第一カバー部材が当接するとともに、他方の端部に前記第二カバー部材が当接して、前記被記録媒体を前記手差し用給紙口へと案内可能な状態になるものであると好ましい。   By the way, in the image forming apparatus of the present invention, the cover member includes a first cover member that covers a part of the manual paper feed port when the cover member is closed, and a remaining portion of the manual paper feed port when the cover member is closed. The first cover member abuts on either one of the two ends of the recording medium when the recording medium is opened, and the other cover member covers the part of the recording medium. It is preferable that the second cover member is brought into contact with an end so that the recording medium can be guided to the manual feed port.

このように構成された画像形成装置によれば、カバー部材が二つの部材から構成されることで、開いたときには、被記録媒体の両端をガイドすることができるので、手差し用給紙口に差し込まれる被記録媒体を、より正確に真っ直ぐに差し込むことができ、斜行を防止または抑制する効果を高めることができる。   According to the image forming apparatus configured as described above, since the cover member is composed of two members, both ends of the recording medium can be guided when the cover member is opened. The recording medium to be recorded can be inserted more accurately and straightly, and the effect of preventing or suppressing skew can be enhanced.

また、本発明の画像形成装置において、前記カバー部材は、閉じられた際に、前記手差し用給紙口への被記録媒体の差し込み方向から見て、前記第一カバー部材の一部と前記第二カバー部材の一部が重なる状態になるものであると好ましい。   In the image forming apparatus according to the aspect of the invention, when the cover member is closed, a part of the first cover member and the first cover member are viewed from the insertion direction of the recording medium into the manual feed port. It is preferable that the two cover members are partially overlapped.

このように構成された画像形成装置によれば、カバー部材が閉じられると、第一カバー部材の一部と第二カバー部材の一部が重なる状態になるので、手差し用給紙口への被記録媒体の差し込み方向から見て、第一カバー部材と第二カバー部材との間には空隙ができなくなる。   According to the image forming apparatus configured as described above, when the cover member is closed, a part of the first cover member and a part of the second cover member overlap each other. When viewed from the insertion direction of the recording medium, there is no gap between the first cover member and the second cover member.

したがって、そのような空隙ができるものに比べ、装置内部へ塵埃が入り込むのを防止または抑制する効果が高く、また、装置内部から発生する音が装置外へ漏れるのを防止または抑制する効果も高くなる。   Therefore, compared with the case where such a gap is formed, the effect of preventing or suppressing the entry of dust into the apparatus is high, and the effect of preventing or suppressing the sound generated from the inside of the apparatus from leaking outside the apparatus is also high. Become.

また、本発明の画像形成装置において、前記カバー部材は、開かれた際に、前記第一カバー部材および前記第二カバー部材が、前記手差し用給紙口の長手方向へ変位可能な構造となっており、前記第一カバー部材および前記第二カバー部材のうち、いずれか一方を前記手差し用給紙口の長手方向へ変位させた際に、その変位方向とは逆方向へ他方を変位させる連動機構が設けられることにより、前記第一カバー部材および前記第二カバー部材は、互いに接近する方向または互いに離間する方向へ連動して変位する構造になっていると好ましい。   In the image forming apparatus of the present invention, when the cover member is opened, the first cover member and the second cover member can be displaced in the longitudinal direction of the manual feed port. When one of the first cover member and the second cover member is displaced in the longitudinal direction of the manual feed port, the other is displaced in the direction opposite to the displacement direction. When the mechanism is provided, it is preferable that the first cover member and the second cover member are structured to be displaced in conjunction with each other in a direction approaching or separating from each other.

このように構成された画像形成装置によれば、第一カバー部材および第二カバー部材が、互いに接近する方向または互いに離間する方向へ連動して変位するので、手差し給紙を行う被記録媒体のサイズ(幅)に応じて、被記録媒体の両端をガイド可能な位置へ第一カバー部材および第二カバー部材を変位させることができる。したがって、いわゆるセンターレジで画像を形成する際に、被記録媒体の位置を簡単かつ確実に最適化することができる。   According to the image forming apparatus configured as described above, the first cover member and the second cover member are displaced in conjunction with each other in a direction approaching or separating from each other. Depending on the size (width), the first cover member and the second cover member can be displaced to positions where both ends of the recording medium can be guided. Therefore, when forming an image with a so-called center register, the position of the recording medium can be optimized easily and reliably.

次に、本発明の実施形態について一例を挙げて説明する。
[画像形成装置の構造]
本実施形態の画像形成装置1は、被記録媒体上に電子写真方式で画像を形成する装置で、図1(c)に示すように、第一給紙部3、第二給紙部5、画像形成部7、排紙部9などを備えている。
Next, an exemplary embodiment of the present invention will be described.
[Structure of image forming apparatus]
An image forming apparatus 1 according to the present embodiment is an apparatus that forms an image on a recording medium by an electrophotographic method. As illustrated in FIG. 1C, the first paper feeding unit 3, the second paper feeding unit 5, An image forming unit 7 and a paper discharge unit 9 are provided.

これらのうち、第一給紙部3では、給紙カセット11に収納された被記録媒体が、給紙カセット11から画像形成部7へと搬送される。また、第二給紙部5では、手差し用給紙口12に差し込まれた被記録媒体が、手差し用給紙口12から画像形成部7へと搬送される。   Among these, in the first paper feeding unit 3, the recording medium stored in the paper feeding cassette 11 is conveyed from the paper feeding cassette 11 to the image forming unit 7. In the second paper feeding unit 5, the recording medium inserted into the manual paper feeding port 12 is conveyed from the manual paper feeding port 12 to the image forming unit 7.

第一給紙部3または第二給紙部5から被記録媒体が搬送されてくると、画像形成部7では、感光体13上に形成された静電潜像を現像ローラ14に担持されたトナーで現像し、その現像された画像が被記録媒体に転写される。   When the recording medium is conveyed from the first paper feeding unit 3 or the second paper feeding unit 5, the electrostatic latent image formed on the photoreceptor 13 is carried on the developing roller 14 in the image forming unit 7. Development is performed with toner, and the developed image is transferred to a recording medium.

そして、その被記録媒体を定着器15で加熱することによって画像を被記録媒体に定着させてから、その被記録媒体を排紙部9へと送り出す。排紙部9では、被記録媒体が排紙トレイ16へと排出される。   Then, the recording medium is heated by the fixing device 15 to fix the image on the recording medium, and then the recording medium is sent to the paper discharge unit 9. In the paper discharge unit 9, the recording medium is discharged to the paper discharge tray 16.

また、この画像形成装置1において、第二給紙部5には、図1(a)および同図(b)に示すように、カバー部材21が設けられている。本実施形態において、カバー部材21は、第一カバー部材21Lおよび第二カバー部材21Rによって構成される。   In the image forming apparatus 1, the second paper feeding unit 5 is provided with a cover member 21 as shown in FIGS. 1A and 1B. In the present embodiment, the cover member 21 includes a first cover member 21L and a second cover member 21R.

これら第一カバー部材21Lおよび第二カバー部材21Rは、装置前面において、いわゆる観音開きで開閉可能な構造になっている。より具体的に説明すると、第一カバー部材21Lは、装置前面から見て左端側にある鉛直な軸線を回転中心にして水平に回動可能、第二カバー部材21Rは、装置前面から見て右端側にある鉛直な軸線を回転中心にして水平に回動可能となっている。   The first cover member 21 </ b> L and the second cover member 21 </ b> R have a structure that can be opened and closed by so-called double doors on the front surface of the apparatus. More specifically, the first cover member 21L can be horizontally rotated around a vertical axis on the left end side when viewed from the front of the apparatus, and the second cover member 21R is positioned at the right end when viewed from the front of the apparatus. It can be rotated horizontally around the vertical axis on the side.

また、第一カバー部材21Lおよび第二カバー部材21Rは、双方とも一方向についての寸法が、その一方向に直交する方向の寸法よりも長い部材となっている(以下、この一方向を、第一カバー部材21Lおよび第二カバー部材21Rの長手方向ともいう。)。   Further, the first cover member 21L and the second cover member 21R are both members whose dimension in one direction is longer than the dimension in the direction orthogonal to the one direction (hereinafter, this one direction is referred to as the first direction). It is also referred to as the longitudinal direction of the one cover member 21L and the second cover member 21R.)

そして、第一カバー部材21Lおよび第二カバー部材21Rは、図1(a)に示すように、第一カバー部材21Lおよび第二カバー部材21Rの長手方向と手差し用給紙口12の長手方向が一致する位置(以下、閉位置ともいう。)へ回動すると、手差し用給紙口12を覆う蓋として機能する状態になる。   The first cover member 21L and the second cover member 21R have a longitudinal direction of the first cover member 21L and the second cover member 21R and a longitudinal direction of the manual feed port 12 as shown in FIG. When it is rotated to a matching position (hereinafter also referred to as a closed position), it will be in a state of functioning as a lid that covers the manual feed port 12.

一方、第一カバー部材21Lおよび第二カバー部材21Rは、図1(b)に示すように、第一カバー部材21Lおよび第二カバー部材21Rの長手方向と手差し用給紙口12への被記録媒体の差し込み方向とが一致する位置(以下、開位置ともいう。)へ回動すると、被記録媒体を手差し用給紙口12へと案内するガイド部として機能する状態になる。   On the other hand, the first cover member 21L and the second cover member 21R are recorded in the longitudinal direction of the first cover member 21L and the second cover member 21R and the manual feed port 12 as shown in FIG. When the recording medium is rotated to a position that coincides with the medium insertion direction (hereinafter also referred to as an open position), the recording medium functions as a guide unit that guides the recording medium to the manual sheet feeding port 12.

[カバー部材の構造の詳細]
次に、上記カバー部材21の構造について、さらに詳細に説明する。
図2(a)〜同図(c)において、第一カバー部材21Lおよび第二カバー部材21Rは、閉位置にあり、この場合、第一カバー部材21Lおよび第二カバー部材21Rの前面は、装置本体の前面1Aと同一面内に収まる位置にある。
[Details of cover member structure]
Next, the structure of the cover member 21 will be described in more detail.
2A to 2C, the first cover member 21L and the second cover member 21R are in the closed position. In this case, the front surfaces of the first cover member 21L and the second cover member 21R are the devices. It is in a position within the same plane as the front surface 1A of the main body.

第一カバー部材21Lおよび第二カバー部材21Rは、図2(a)〜同図(c)に示すように、第一ガイド軸23L,23R、および第二ガイド軸24L,24Rを備えている。また、これら第一ガイド軸23L,23R、および第二ガイド軸24L,24Rは、装置本体側に形成された第一ガイド溝25L,25R、および第二ガイド溝26L,26Rに嵌め込まれている。   The first cover member 21L and the second cover member 21R include first guide shafts 23L and 23R and second guide shafts 24L and 24R, as shown in FIGS. The first guide shafts 23L and 23R and the second guide shafts 24L and 24R are fitted into first guide grooves 25L and 25R and second guide grooves 26L and 26R formed on the apparatus main body side.

これらのうち、第一ガイド軸23L,23Rは、第一カバー部材21Lおよび第二カバー部材21Rを開閉させる際に、回動中心となる部分である。より具体的には、第一カバー部材21Lおよび第二カバー部材21Rは、第一ガイド軸23L,23Rを中心に回動することで、図2(a)に示した閉位置から、図3(a)に示す矢印S1方向へと移動して図3(a)に示す開位置に至る。このとき、第二ガイド軸24L,24Rは、第二ガイド溝26L,26Rに沿って第一ガイド軸23L,23Rの周囲を旋回する。   Among these, the first guide shafts 23L and 23R are portions that become the center of rotation when the first cover member 21L and the second cover member 21R are opened and closed. More specifically, the first cover member 21L and the second cover member 21R are rotated about the first guide shafts 23L and 23R so that the closed position shown in FIG. It moves to the arrow S1 direction shown to a), and reaches the open position shown to Fig.3 (a). At this time, the second guide shafts 24L and 24R turn around the first guide shafts 23L and 23R along the second guide grooves 26L and 26R.

すなわち、第二ガイド溝26Lは、図4(a)、図4(b)、図5(a)、図5(b)、および図5(c)に示す通り、一部が第一ガイド溝25Lの一端を中心とする円弧を描く溝になっている。そのため、上記第一ガイド溝25Lの一端に第一ガイド軸23Lがある場合、第二ガイド軸24Lは、第一ガイド溝25Lの一端を中心とする円弧に沿って移動可能で、この場合、第一カバー部材21Lは、開位置と閉位置との間を回動可能となる。   That is, the second guide groove 26L is partially a first guide groove as shown in FIGS. 4 (a), 4 (b), 5 (a), 5 (b), and 5 (c). It is a groove that draws an arc centered on one end of 25L. Therefore, when the first guide shaft 23L is at one end of the first guide groove 25L, the second guide shaft 24L is movable along an arc centered on one end of the first guide groove 25L. The one cover member 21L can rotate between an open position and a closed position.

また、第一カバー部材21Lおよび第二カバー部材21Rは、図3(a)に示す開位置に至る開位置に至ると、さらに図3(b)に示す矢印S2方向へと移動可能となる。すなわち、第一ガイド溝25Lは、図5(a)〜同図(c)に示す通り、一方向に直線的に延びる形態となっていて、第二ガイド溝26Lは、上述の円弧を描く部分以外に、第一ガイド溝25Lと同一方向に延びる部分を備えている。そのため、第一カバー部材21Lが開位置にある場合、第一ガイド軸23Lおよび第二ガイド軸24Lは、第一ガイド溝25Lおよび第二ガイド溝26Lに沿って直線的に移動でき、そのような方向へ第一カバー部材21Lを移動させることで、第一カバー部材21Lと第二カバー部材21Rとの間隔を任意に変更することができる。   Further, when the first cover member 21L and the second cover member 21R reach the open position that reaches the open position shown in FIG. 3A, the first cover member 21L and the second cover member 21R can further move in the arrow S2 direction shown in FIG. That is, the first guide groove 25L has a form extending linearly in one direction as shown in FIGS. 5A to 5C, and the second guide groove 26L is a portion that draws the above-described arc. In addition, a portion extending in the same direction as the first guide groove 25L is provided. Therefore, when the first cover member 21L is in the open position, the first guide shaft 23L and the second guide shaft 24L can move linearly along the first guide groove 25L and the second guide groove 26L. By moving the first cover member 21L in the direction, the distance between the first cover member 21L and the second cover member 21R can be arbitrarily changed.

しかも、第一カバー部材21Lと第二カバー部材21Rとの間の間隔を縮めた場合、第二ガイド軸24Lは、第二ガイド溝26Lの円弧状部分から外れるため、この時点で第一カバー部材21Lは、第一ガイド軸23Lを中心とする回動ができない状態になる。したがって、第一カバー部材21Lは、回動することなく、第一ガイド溝25Lが延びる方向へのみ移動可能となり、予期しない位置で第一カバー部材21Lが閉じられてしまうことはない。   In addition, when the interval between the first cover member 21L and the second cover member 21R is reduced, the second guide shaft 24L is disengaged from the arc-shaped portion of the second guide groove 26L. 21L is in a state where it cannot rotate about the first guide shaft 23L. Therefore, the first cover member 21L can move only in the direction in which the first guide groove 25L extends without rotating, and the first cover member 21L is not closed at an unexpected position.

また、第一カバー部材21Lが図2(a)に示したが閉位置にある場合、図5(a)に示すように、第二ガイド軸24Lは、トルクばね27Lによって移動が軽く規制された状態にある。このような構成を採用すると、第一カバー部材21Lが閉位置にある場合に、予期しない軽微な力を受けて第一カバー部材21Lが開いてしまうのを防止することができる。   When the first cover member 21L is in the closed position as shown in FIG. 2A, the movement of the second guide shaft 24L is lightly restricted by the torque spring 27L as shown in FIG. 5A. Is in a state. When such a configuration is employed, it is possible to prevent the first cover member 21L from opening due to an unexpected slight force when the first cover member 21L is in the closed position.

ちなみに、第一カバー部材21Lを閉位置から開位置へ移動させる際には、第一カバー部材21Lにある程度以上の強い力を加えると、第二ガイド軸24Lは、トルクばね27Lの一部を図5(b)中に示した矢印S3方向に押し退けることができる。したがって、第二ガイド軸24Lは、図5(b)中に示した矢印S1方向へと移動することができ、第一カバー部材21Lを開位置へ移動させることができる。   Incidentally, when the first cover member 21L is moved from the closed position to the open position, if a strong force of a certain level or more is applied to the first cover member 21L, the second guide shaft 24L is configured to show a part of the torque spring 27L. 5 (b) can be pushed away in the direction of arrow S3. Therefore, the second guide shaft 24L can move in the direction of arrow S1 shown in FIG. 5B, and the first cover member 21L can be moved to the open position.

なお、第二カバー部材21Rは、図2(a)から明らかなように、第一カバー部材21Lと左右対称にはなるものの、同様な仕組みによって開位置と閉位置との間を回動可能となる。また、開位置へ移動した場合は、第一ガイド溝25Rが延びる方向へ移動可能となり、その移動中は、第一ガイド軸23Rを中心とする回動ができない状態になる。   As is clear from FIG. 2A, the second cover member 21R is symmetrical with the first cover member 21L, but can be rotated between the open position and the closed position by the same mechanism. Become. Further, when moved to the open position, the first guide groove 25R can be moved in the extending direction, and during the movement, the first guide shaft 23R cannot be turned around.

さらに、第一カバー部材21Lおよび第二カバー部材21Rの下面側には、図2(d)に示すように、長手方向にスライド可能なスライドラック31L,31Rと、これらと噛み合うピニオンギア33が配設されている。第一カバー部材21Lと第二カバー部材21Rは、スライドラック31L,31Rに対して、回動軸35L,35Rを中心に回動可能な状態で連結されている。   Further, on the lower surface side of the first cover member 21L and the second cover member 21R, as shown in FIG. 2D, slide racks 31L and 31R that are slidable in the longitudinal direction and a pinion gear 33 that meshes with these are arranged. It is installed. The first cover member 21L and the second cover member 21R are connected to the slide racks 31L and 31R so as to be rotatable about the rotation shafts 35L and 35R.

このような構成を採用すると、第一カバー部材21Lおよび第二カバー部材21Rが開位置にある場合に、図3(c)に示すように、いずれか一方を第一ガイド軸23Lおよび第二ガイド軸24Lの延びる方向(図3(c)中の矢印S2方向)へ移動させると、それに連動してスライドラック31L,31Rの一方がスライドし、それに伴ってピニオンギア33が回動し、スライドラック31L,31Rの他方が、一方とは反対方向にスライドする。   When such a configuration is adopted, when the first cover member 21L and the second cover member 21R are in the open position, as shown in FIG. When the shaft 24L is moved in the direction in which the shaft 24L extends (the direction of the arrow S2 in FIG. 3C), one of the slide racks 31L and 31R slides in conjunction with the movement, and the pinion gear 33 rotates accordingly. The other of 31L and 31R slides in the opposite direction to the other.

したがって、第一カバー部材21Lおよび第二カバー部材21Rのいずれか一方を移動させるだけで、他方が連動して移動し、双方間の中間点を変位させることなく、第一カバー部材21Lと第二カバー部材21Rとの間隔を変更することができる。   Therefore, by moving only one of the first cover member 21L and the second cover member 21R, the other moves in conjunction with each other, and the first cover member 21L and the second cover member 21L are not displaced without displacing the intermediate point between them. The distance from the cover member 21R can be changed.

加えて、第一カバー部材21Lには、図2(e)に示すように、第二カバー部材21R側に向かって突出する凸部37が設けられ、第二カバー部材21Rには、凸部37が嵌り込む凹部39が設けられている。   In addition, as shown in FIG. 2E, the first cover member 21L is provided with a convex portion 37 that protrudes toward the second cover member 21R side, and the convex portion 37 is provided on the second cover member 21R. A recessed portion 39 into which is fitted is provided.

このような構造を採用することで、第一カバー部材21Lおよび第二カバー部材21Rが閉じられた際には、手差し用給紙口12への被記録媒体の差し込み方向(すなわち、画像形成装置1の前面側)から見て、第一カバー部材21Lの一部と第二カバー部材21Rの一部が重なる状態になる。   By adopting such a structure, when the first cover member 21L and the second cover member 21R are closed, the direction in which the recording medium is inserted into the manual feed port 12 (that is, the image forming apparatus 1). When viewed from the front side), a part of the first cover member 21L and a part of the second cover member 21R overlap.

したがって、手差し用給紙口12への被記録媒体の差し込み方向から見て、第一カバー部材21Lの一部と第二カバー部材21Rの間に空隙ができないので、装置内部へ塵埃が入り込むのを防止または抑制する効果が高なる。また、画像形成装置1の内部から発生する音が装置外へ漏れるのを防止または抑制する効果も高くなる。   Therefore, when viewed from the insertion direction of the recording medium into the manual paper feed port 12, there is no gap between a part of the first cover member 21L and the second cover member 21R, so that dust can enter the apparatus. The effect of preventing or suppressing increases. In addition, the effect of preventing or suppressing sound generated from the inside of the image forming apparatus 1 from leaking out of the apparatus is enhanced.

[効果]
以上説明した通り、上記画像形成装置1によれば、手差し用給紙口12を覆うカバー部材21(第一カバー部材21Lおよび第二カバー部材21R)を開くことにより、被記録媒体を手差し用給紙口12へと案内するガイド部として利用することができる。
[effect]
As described above, according to the image forming apparatus 1, the recording medium is manually fed by opening the cover member 21 (the first cover member 21L and the second cover member 21R) that covers the manual feed port 12. It can be used as a guide portion for guiding to the paper mouth 12.

しかも、カバー部材21を開いた際には、カバー部材21の長手方向が被記録媒体の差し込み方向と一致するので、高さ方向寸法の小さいカバーが下端を軸に手前に傾いてガイド部となるものとは異なり、被記録媒体を案内可能な距離を十分に確保できる。   In addition, when the cover member 21 is opened, the longitudinal direction of the cover member 21 coincides with the insertion direction of the recording medium. Therefore, the cover having a small height dimension is tilted forward with the lower end as an axis to become a guide portion. Unlike those, it is possible to secure a sufficient distance for guiding the recording medium.

したがって、被記録媒体の斜行を防止または抑制することができ、ひいては被記録媒体の斜行に起因する紙詰まりの発生や被記録媒体における皺の発生などを抑制できる。また、利用者が手差し用給紙口12からの給紙作業を行う際に、被記録媒体を真っ直ぐに差し込むことが容易になるので、被記録媒体を案内可能な距離が短い場合に比べ、差し込み方向の微妙な調整が不要となり、給紙作業をスムーズに実施することができる。   Therefore, it is possible to prevent or suppress the skew of the recording medium, and it is possible to suppress the occurrence of a paper jam caused by the skew of the recording medium and the occurrence of wrinkles on the recording medium. In addition, when the user performs the paper feeding operation from the manual paper feeding port 12, it becomes easy to insert the recording medium straight, so that the insertion of the recording medium is shorter than when the guideable distance of the recording medium is short. Subtle adjustment of the direction becomes unnecessary, and the paper feeding operation can be carried out smoothly.

また、上記画像形成装置1によれば、カバー部材21が二つの部材(第一カバー部材21Lおよび第二カバー部材21R)から構成されることで、開いたときには、被記録媒体の両端をガイドすることができるので、手差し用給紙口12に差し込まれる被記録媒体を、より正確に真っ直ぐに差し込むことができ、斜行を防止または抑制する効果を高めることができる。   Further, according to the image forming apparatus 1, the cover member 21 includes two members (the first cover member 21L and the second cover member 21R), and guides both ends of the recording medium when opened. Therefore, the recording medium to be inserted into the manual feed port 12 can be inserted more accurately and straightly, and the effect of preventing or suppressing skew can be enhanced.

また、上記画像形成装置1によれば、第一カバー部材21Lおよび第二カバー部材21Rが、互いに接近する方向または互いに離間する方向へ連動して変位するので、手差し給紙を行う被記録媒体のサイズ(幅)に応じて、被記録媒体の両端をガイド可能な位置へ第一カバー部材21Lおよび第二カバー部材21Rを変位させることができる。したがって、いわゆるセンターレジで画像を形成する際に、被記録媒体の位置を簡単かつ確実に最適化することができる。   Further, according to the image forming apparatus 1, the first cover member 21L and the second cover member 21R are displaced in conjunction with each other in a direction approaching or separating from each other. Depending on the size (width), the first cover member 21L and the second cover member 21R can be displaced to positions where both ends of the recording medium can be guided. Therefore, when forming an image with a so-called center register, the position of the recording medium can be optimized easily and reliably.

さらに、上記画像形成装置1において、カバー部材21は、手差し用給紙口12の長手方向へ変位させた際、特定の位置へ変位したときには開閉可能となる一方、前記特定の位置以外の位置へ変位したときには開かれた状態を維持する構造になっている。すなわち、本実施形態の場合であれば、第一カバー部材21Lおよび第二カバー部材21Rが開位置にある場合、いくらかスライドさせると回動ができない状態になることで、上記開位置にある状態が維持される構造になっている。   Further, in the image forming apparatus 1, when the cover member 21 is displaced in the longitudinal direction of the manual feed port 12, the cover member 21 can be opened and closed when the cover member 21 is displaced to a specific position, while being moved to a position other than the specific position. It is structured to maintain an open state when displaced. That is, in the case of the present embodiment, when the first cover member 21L and the second cover member 21R are in the open position, if the slide is somewhat slid, the rotation cannot be performed. The structure is maintained.

したがって、このような構造を採用すれば、前記特定の位置以外の位置へ変位させる際に、カバー部材21が想定外の位置で閉じられてしまうのを防止でき、第一カバー部材21Lおよび第二カバー部材21Rを変位させる作業を容易に実施できる。   Therefore, if such a structure is employed, the cover member 21 can be prevented from being closed at an unexpected position when being displaced to a position other than the specific position, and the first cover member 21L and the second cover member 21L can be prevented. The operation of displacing the cover member 21R can be easily performed.

また、カバー部材21をいくらか変位させた後は、第一カバー部材21Lおよび第二カバー部材21Rが確実に開いた状態を維持できるので、第一カバー部材21Lおよび第二カバー部材21Rカバー部材の手差し用給紙口12に対する傾きを最適な状態で維持でき、被記録媒体の斜行を防止または抑制する効果を高めることができる。   In addition, since the first cover member 21L and the second cover member 21R can be reliably maintained in an open state after the cover member 21 is somewhat displaced, manual feed of the first cover member 21L and the second cover member 21R cover member Therefore, it is possible to maintain the inclination with respect to the paper feeding port 12 in an optimum state, and to enhance the effect of preventing or suppressing the skew of the recording medium.
