It is a perspective view which shows the engaging state with the opening / closing member 110 of the accommodating device 80 (not shown).
Hereinafter, the configuration and operation of the release device 90 will be described with reference to the drawings, but the same components as those of the image forming apparatus 1 according to the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. ..
(1) Configuration of Release Device As shown in FIG. 5, a second accommodating device 80 is attached to the image forming apparatus 1 on the mounting surface side when the accommodating device 80 is attached to or detached from the image forming apparatus 1 main body. A part of the hook member 91 and the link member 96 constituting the release device 90 that opens and closes the opening / closing member 110 is provided so as to project. In the release device 90, as shown in FIG. 7, when the accommodating device 80 is attached to the main body of the image forming device 1, the hook portion 93 of the hook member 91 slips into the back surface side of the operation handle 111 of the second opening / closing member 110. It is located in a state of being.

図６に示すように、解除装置９０はフック部材９１と、フック部材９１を操作ハンドル１１１から離間させる方向に付勢する付勢手段としてのトーションバネ９５と、リンク部材９６から構成されている。 As shown in FIG. 6, the release device 90 includes a hook member 91, a torsion spring 95 as an urging means for urging the hook member 91 in a direction away from the operation handle 111, and a link member 96.

フック部材９１は、回転軸９２の一端側に全体形状が鉤型のフック部９３が固定され、他端側にはアーム部９４が固定されている。フック部９３は先端部９３ａが断面視大きなＲ形状とされ、第２の開閉部材１１０の操作ハンドル１１１の裏面側に潜り込む際の誘い込み部を形成している。アーム部９４は、リンク部材９６と接触している状態ではトーションバネ９５によって回転付勢されているフック部材９１の回転を阻止している。 In the hook member 91, a hook portion 93 having a hook shape as a whole is fixed to one end side of the rotating shaft 92, and an arm portion 94 is fixed to the other end side. The hook portion 93 has an R-shaped tip portion 93a having a large cross-sectional view, and forms an invitation portion when slipping into the back surface side of the operation handle 111 of the second opening / closing member 110.

FIG. 5 is a schematic cross-sectional view showing a state in which the hook member 91 enters the back surface side of the operation handle 111 of the second opening / closing member 110 by moving in the mounting direction.
Hereinafter, the opening / closing operation of the second opening / closing member 110 accompanying the movement of the accommodating device 80 will be described with reference to the drawings.

（２．１）第２の開閉部材の開放位置への移動
図８に示すように、収容装置８０が画像形成装置１本体に装着された状態では、第２の開閉部材１１０の係合部１１２がトレイモジュール７０の被係合部７１に係合した状態で、解除装置９０のフック部材９１が第２の開閉部材１１０の操作ハンドル１１１の裏面側に入り込んでいる。
係る状態から、例えば、開閉部材１００を開放位置へ移動させると、図９に示ように、収容装置８０が画像形成装置１本体から離間する方向に移動（図中 Ｒ参照）を開始して、操作ハンドル１１１がフック部材９１のフック部９３により回転力を受けて、第２の開閉部材１１０の係合部１１２とトレイモジュール７０の被係合部７１との係合が解除される。 (2.1) Movement of the Second Opening / Closing Member to the Opening Position As shown in FIG. 8, when the accommodating device 80 is attached to the main body of the image forming apparatus 1, the engaging portion 112 of the second opening / closing member 110 Is engaged with the engaged portion 71 of the tray module 70, and the hook member 91 of the releasing device 90 is inserted into the back surface side of the operation handle 111 of the second opening / closing member 110.
From such a state, for example, when the opening / closing member 100 is moved to the open position, as shown in FIG. 9, the accommodating device 80 starts moving in the direction away from the main body of the image forming apparatus 1 (see R in the figure). The operation handle 111 receives a rotational force from the hook portion 93 of the hook member 91, and the engagement portion 112 of the second opening / closing member 110 and the engaged portion 71 of the tray module 70 are disengaged.

図１０に示すように、収容装置８０の画像形成装置１本体からの離間に伴って、画像形成装置１本体（図中 二点鎖線で示す）に向って移動可能に付勢されたリンク部材９６が画像形成装置１本体側へ移動して、フック部材９１のアーム部９４との接触が解除され、フック部材９１のフック部９３は、トーションバネ９５の付勢力によって操作ハンドル１１１から抜けるように回転する（図中 矢印Ｒ１参照）。 As shown in FIG. 10, the link member 96 is urged to move toward the image forming apparatus 1 main body (indicated by the alternate long and short dash line) as the accommodating device 80 is separated from the image forming apparatus 1 main body. Moves to the image forming apparatus 1 main body side, the contact of the hook member 91 with the arm portion 94 is released, and the hook portion 93 of the hook member 91 rotates so as to come out of the operation handle 111 by the urging force of the torsion spring 95. (See arrow R1 in the figure).

フック部材９１のフック部９３が操作ハンドル１１１から抜けて、収容装置８０が更に画像形成装置１本体からの離間するように移動すると、第２の開閉部材１１０は図１１に示すように、開放位置まで移動してトレイモジュール７０の第２の用紙搬送路Ｓ２が開放されてジャム除去が可能な状態となる。
このように、トレイモジュール７０が接続された画像形成装置１において、画像形成装置１本体の側部に収容装置８０が接続された状態で、開閉部材１００の開放操作を行うことで、収容装置８０が離間するように移動しながら、トレイモジュール７０の第２の開閉部材１１０を開放位置へ移動させ、容易にジャム除去を行うことができる。 When the hook portion 93 of the hook member 91 comes out of the operation handle 111 and the accommodating device 80 further moves away from the main body of the image forming apparatus 1, the second opening / closing member 110 is in the open position as shown in FIG. The second paper transport path S2 of the tray module 70 is opened, and the jam can be removed.
In this way, in the image forming apparatus 1 to which the tray module 70 is connected, the accommodating device 80 is opened by opening and closing the opening / closing member 100 in a state where the accommodating device 80 is connected to the side portion of the image forming apparatus 1 main body. The second opening / closing member 110 of the tray module 70 can be moved to the open position while moving so as to be separated from each other, and the jam can be easily removed.

（２．２）第２の開閉部材の閉鎖位置への移動
開放された第２の開閉部材１１０を閉塞位置に移動させる場合には、図１２に示すように、収容装置８０を画像形成装置１本体側へ向って移動（図中 矢印Ｒ参照）させると、収容装置８０が第２の開閉部材１１０の外面１１０ａと接触して第２の開閉部材１１０をトレイモジュール７０に向って移動させる。 (2.2) Movement of the Second Opening / Closing Member to the Closed Position When the opened second opening / closing member 110 is moved to the closed position, as shown in FIG. 12, the accommodating device 80 is moved to the image forming device 1. When the accommodating device 80 is moved toward the main body (see the arrow R in the drawing), the accommodating device 80 comes into contact with the outer surface 110a of the second opening / closing member 110 and moves the second opening / closing member 110 toward the tray module 70.

係る状態で、コイルスプリング９７の付勢力で画像形成装置１本体側へ突出したリンク部材９６が画像形成装置１本体（図中 二点鎖線で示す）に接触して移動する収容装置８０側へ移動（図中 矢印Ｒ２参照）して、アーム部９４と接触して、トーションバネ９５で操作ハンドル１１１とは離間する方向に付勢されたフック部材９１を上方（Ｚ方向）に回転させる（図中 矢印Ｒ１参照）。その結果、先端部９３ａが断面視大きなＲ形状とされたフック部９３は操作ハンドル１１１の裏面側へ入り込む状態となる。 In this state, the link member 96 protruding toward the image forming apparatus 1 main body by the urging force of the coil spring 97 moves to the accommodating device 80 side which moves in contact with the image forming apparatus 1 main body (indicated by the alternate long and short dash line). (Refer to the arrow R2 in the figure), the hook member 91 urged by the torsion spring 95 in a direction away from the operation handle 111 is rotated upward (Z direction) in contact with the arm portion 94 (in the figure). See arrow R1). As a result, the hook portion 93 having the tip portion 93a having an R shape having a large cross-sectional view is in a state of entering the back surface side of the operation handle 111.

更に収容装置８０が画像形成装置１本体側へ移動すると、図９に示すような第２の開閉部材１１０の係合部１１２がトレイモジュール７０の被係合部７１に係合する直前の状態を経て、図８に示すように、第２の開閉部材１１０の係合部１１２がトレイモジュール７０の被係合部７１に係合する。
そして、収容装置８０が画像形成装置１本体に装着された状態では、解除装置９０のフック部９３は操作ハンドル１１１の裏面側に入り込んで係合した状態となる。 Further, when the accommodating device 80 moves toward the main body of the image forming apparatus 1, the state immediately before the engaging portion 112 of the second opening / closing member 110 as shown in FIG. 9 engages with the engaged portion 71 of the tray module 70 is displayed. Then, as shown in FIG. 8, the engaging portion 112 of the second opening / closing member 110 engages with the engaged portion 71 of the tray module 70.
Then, in the state where the accommodating device 80 is attached to the main body of the image forming apparatus 1, the hook portion 93 of the releasing device 90 enters and engages with the back surface side of the operation handle 111.

尚、第２の開閉部材１１０の開閉に際しては、開閉部材１００の開放操作は行わず、収容装置８０のみを画像形成装置１本体から離間するように移動させ、また、離間した収容装置８０のみを画像形成装置１本体側へ移動させて接続してもよい。 When opening and closing the second opening / closing member 110, the opening / closing member 100 is not opened, only the accommodating device 80 is moved so as to be separated from the main body of the image forming apparatus 1, and only the separated accommodating device 80 is moved. The image forming apparatus 1 may be moved to the main body side and connected.

本実施形態に係る画像形成装置１によれば、給紙装置２０の下方にトレイモジュール７０が接続されている場合であっても、用紙搬送装置８０の移動操作に連動して第２の開閉部材１１０の開閉を行い、容易にジャム除去を行うことができる。 According to the image forming apparatus 1 according to the present embodiment, even when the tray module 70 is connected below the paper feeding device 20, the second opening / closing member is linked to the moving operation of the paper conveying device 80. The 110 can be opened and closed to easily remove the jam.
