When the covering member 22 is not closed, the protrusion 72 separates from the interlock switch 70, the interlock switch 70 is turned off, and the power supply to each part of the image forming apparatus 10 is prohibited.

上述した被覆部材２２を開閉するための開閉装置が設けられている。図５には、開閉装置７４の概略が示されている。 An opening/closing device for opening/closing the covering member 22 described above is provided. FIG. 5 shows an outline of the opening/closing device 74.

開閉装置７４は、前述した画像形成装置本体１２に係り止めする第１の係止部７６と第２の係止部７８とを有する。第１の係止部７６は、図中右側（＋Ｚ方向）に突出した第１の爪部８０が形成されている。一方、画像形成装置本体側には第１の被係止部８２が形成されている。被覆部材２２が閉じられると、第１の被係止部８２に第１の爪部８０が係り止めされる。 The opening/closing device 74 has the first locking portion 76 and the second locking portion 78 that are locked to the image forming apparatus main body 12 described above. The first locking portion 76 is formed with a first claw portion 80 protruding rightward (+Z direction) in the drawing. On the other hand, a first locked portion 82 is formed on the image forming apparatus main body side. When the covering member 22 is closed, the first claw portion 80 is locked to the first locked portion 82.

また、第２の係止部７８は、図中左側（−Ｚ方向）に突出した第２の爪部８４が形成されている。一方、画像形成装置本体側であって、前述した表示装置１４が配置される表示装置配置部８６には第２の被係止部８８が形成されている。被覆部材２２が閉じられると、第２の被係止部８８に第２の爪部８４が係り止めされる。 Further, the second locking portion 78 is formed with a second claw portion 84 that protrudes to the left side (-Z direction) in the drawing. On the other hand, on the image forming apparatus main body side, a second locked portion 88 is formed in the display device placement portion 86 in which the display device 14 is placed. When the covering member 22 is closed, the second claw portion 84 is locked to the second locked portion 88.

第１の係止部７６は、Ｚ方向に延びる第１の連結部９０と一体に形成されて該第１の連結部９０に連結されている。また、この第１の連結部９０のＺ方向端に前述した操作部２３が形成されている。 The first locking portion 76 is integrally formed with the first connecting portion 90 extending in the Z direction and connected to the first connecting portion 90. Further, the operation portion 23 described above is formed at the Z direction end of the first connecting portion 90.

第２の連結部９２は、第２の係止部７８と第１の連結部９０とを連結している。この第２の連結部９２は、操作部２３を−Ｚ方向に押圧して第１の係止部７６の係り止めを解除するように移動させると、第２の係止部７８が第１の係止部７６へ近づく方向、即ち＋Ｚ方向に移動する。 The second connecting portion 92 connects the second locking portion 78 and the first connecting portion 90. When the second connecting portion 92 is moved so as to release the locking of the first locking portion 76 by pressing the operation portion 23 in the −Z direction, the second locking portion 78 is moved to the first locking portion 78. It moves in the direction approaching the locking portion 76, that is, in the +Z direction.

また、第１の係止部７６の画像形成装置本体側には、第１の係止部７６を案内する案内部９４が設けられている。この案内部９４は、被覆部材２２が開いた状態から閉じられる状態まで第１の係止部７６がＺ方向の係止位置へ移動しないように第１の係止部７６の先端を案内する。 Further, a guide portion 94 that guides the first locking portion 76 is provided on the image forming apparatus main body side of the first locking portion 76. The guide portion 94 guides the tip end of the first locking portion 76 so that the first locking portion 76 does not move to the locking position in the Z direction from the open state to the closed state of the covering member 22.

また、前述したインターロックスイッチ７０は、第２の係止部７８が第２の被係止部８８に係り止めする位置まで移動した場合にオンとなる位置に配置され、第２の係止部７８が第２の被係止部８８まで移動していない状態にあっては、インターロックスイッチ７０はオフとされる。 Further, the interlock switch 70 described above is arranged at a position that is turned on when the second locking portion 78 moves to a position where it is locked by the second locked portion 88, and the second locking portion is provided. When 78 is not moved to the second locked portion 88, the interlock switch 70 is turned off.

今、被覆部材２２が閉じられている状態にあって、使用者が操作部２３を−Ｚ方向に押圧した場合は、第１の連結部９０が−Ｚ方向に移動し、第１の係止部７６の第１の被係止部８２との係り止めが解除される。一方、第１の連結部９０が−Ｚ方向に移動すると、第２の係止部７８が時計方向に回転し、第２の係止部７８の第２の被係止部８８との係り止めが解除される。 When the user presses the operating portion 23 in the −Z direction with the covering member 22 being closed, the first connecting portion 90 moves in the −Z direction and the first locking is performed. The engagement of the portion 76 with the first locked portion 82 is released. On the other hand, when the first connecting portion 90 moves in the -Z direction, the second locking portion 78 rotates clockwise, and the second locking portion 78 is locked to the second locked portion 88. Is released.

次に被覆部材２２を閉じる場合は、第１の係止部７６は、図５において２点鎖線で示すように、案内部９４に案内され、Ｚ方向の位置を保ちながら閉じる方向へ移動する。第１の係止部７６が係り止めする位置まで移動すると、図示しない弾性体により第１の連結部９０がＺ方向へ移動し、第１の係止部７６の第１の爪部８０が第１の被係止部８２に入り込み、第１の係止部７６が第１の被係止部８２に係り止めされる。 Next, when closing the covering member 22, the first locking portion 76 is guided by the guide portion 94 and moves in the closing direction while maintaining the position in the Z direction, as shown by the chain double-dashed line in FIG. When the first locking portion 76 moves to the position where it is locked, the first connecting portion 90 moves in the Z direction by an elastic body (not shown), and the first claw portion 80 of the first locking portion 76 moves to the first position. The first locked portion 76 enters the first locked portion 82, and the first locked portion 76 is locked to the first locked portion 82.

第１の係止部７６が第１の被係止部８２に係り止めされていない状態にあっては、第１の係止部７６が案内部９４に案内されて第１の連結部９０が−Ｚ方向にずれた位置にあるので、第２の係止部７８は、図５において２点鎖線で示すように、＋Ｚ方向にずれた位置を保つ。このため、例えば被覆部材２２がゆがんでいたとしても、第１の係止部７６が第１の被係止部８２に係り止めされない限り、第２の係止部７８が第２の被係止部８８に係り止めされることはない。 In a state where the first locking portion 76 is not locked to the first locked portion 82, the first locking portion 76 is guided by the guide portion 94, and the first connecting portion 90 moves. Since the second locking portion 78 is located at the position shifted in the −Z direction, the second locking portion 78 maintains the position displaced in the +Z direction, as indicated by the chain double-dashed line in FIG. Therefore, even if the covering member 22 is distorted, for example, unless the first locking portion 76 is locked by the first locked portion 82, the second locking portion 78 is locked by the second locked portion 78. It is not locked by the portion 88.

また、第１の係止部７６が第１の被係止部８２に係り止めされているが、第２の係止部７８が第２の被係止部８８の位置まで移動していない状態（半ラッチ状態）においては、インターロックスイッチ７０が入るおそれがない。 Further, the first locking portion 76 is locked to the first locked portion 82, but the second locking portion 78 has not moved to the position of the second locked portion 88. In the (half-latched state), there is no possibility that the interlock switch 70 will be turned on.

さらに開閉装置７４を図６から図１２を用いて詳細に説明する。
図６は、被覆部材２２の上部被覆部２２ａを裏側から見た平面図である。裏側から見ているので、Ｚ方向が逆になっている。 Further, the opening/closing device 74 will be described in detail with reference to FIGS. 6 to 12.
FIG. 6 is a plan view of the upper covering portion 22a of the covering member 22 as viewed from the back side. As viewed from the back side, the Z direction is reversed.

図８にも示すように、第１の連結部９０の中央付近には、付勢部材９６が設けられている。この付勢部材９６は例えば圧縮コイルばねで、この付勢部材９６の一端が第１の連結部９０に係合し、他端が被覆部材２２に係合し、被覆部材２２に対して第１の連結部９０を＋Ｚ方向に付勢している。したがって、前述した操作部２３を−Ｚ方向へ押圧すると、この付勢部材９６の付勢力により第１の連結部９０には元に位置にもどろうとする力が作用する。 As shown in FIG. 8, a biasing member 96 is provided near the center of the first connecting portion 90. The biasing member 96 is, for example, a compression coil spring. One end of the biasing member 96 engages with the first connecting portion 90, the other end engages with the covering member 22, and the first biasing member 96 with respect to the covering member 22. The connecting portion 90 of is urged in the +Z direction. Therefore, when the above-mentioned operation portion 23 is pressed in the −Z direction, a force for returning to the original position acts on the first connecting portion 90 due to the urging force of the urging member 96.

また、第１の連結部９０の両端付近には、Ｚ方向を長手方向とする第１の長穴９８及び第２の長穴１００が形成されている。この第１の長穴９８と第２の長穴１００には、被覆部材２２から突出した第１の突出部１０２及び第２の突出部１０４が挿入されており、被覆部材２２に対して第１の連結部９０がＺ方向へ移動自在であるように支持している。 Further, in the vicinity of both ends of the first connecting portion 90, a first elongated hole 98 and a second elongated hole 100 whose longitudinal direction is the Z direction are formed. A first projecting portion 102 and a second projecting portion 104 projecting from the covering member 22 are inserted into the first elongated hole 98 and the second elongated hole 100, and the first protruding portion 102 and the second protruding portion 104 are inserted into the first elongated hole 98 and the second elongated hole 100 with respect to the covering member 22. The connecting portion 90 of the above is supported so as to be movable in the Z direction.

また、図７及び図９に示すように、前述した操作部２３は、Ｚ方向に摺動自在であるように、被覆部材２２に形成された操作部用摺動部１０６に挿入されている。したがって、第１の係止部７６は、第１の係止部７６を挟んだＺ方向の両側で、第１の突出部１０２と操作部用摺動部１０６によりＸ方向の移動ができないように支持されているので、第１の係止部７６がＸ方向の荷重を受けても第１の係止部７６が倒れるのを防止する。 Further, as shown in FIGS. 7 and 9, the above-mentioned operating portion 23 is inserted into the operating portion sliding portion 106 formed on the covering member 22 so as to be slidable in the Z direction. Therefore, the first locking portion 76 is prevented from moving in the X direction by the first protrusion 102 and the operating portion sliding portion 106 on both sides of the first locking portion 76 in the Z direction. Since the first locking portion 76 is supported, the first locking portion 76 is prevented from falling down even if the first locking portion 76 receives a load in the X direction.

また、図９に示しように、第１の係止部７６の第１の爪部８０は、画像形成装置本体１２側に設けられた孔としての被係止部８２に係る止めされている。案内部９４は、被係止部８２から−Ｘ方向へ延びる壁として形成されている。被覆部材２２は、支点軸４４を中心として回転するが、案内部９４は、被覆部材２２の回転中は、第２の係止部７８を案内するだけのＹ方向の幅をもっている。ただし、被覆部材２２の回転軌跡に合わせて円弧状に形成してもよい。 Further, as shown in FIG. 9, the first claw portion 80 of the first locking portion 76 is locked by the locked portion 82 as a hole provided on the image forming apparatus main body 12 side. The guide portion 94 is formed as a wall extending from the locked portion 82 in the −X direction. The covering member 22 rotates about the fulcrum shaft 44, but the guide portion 94 has a width in the Y direction that guides the second locking portion 78 while the covering member 22 is rotating. However, it may be formed in an arc shape according to the rotation trajectory of the covering member 22.

図１２に示すように、第２の係止部７８の第２の爪部８４は、画像形成装置本体１２側に設けられた表示装置配置部８６に孔として形成された第２の被係止部８８に係り止めされている。また、図６、図１１及び図１２に示すように、第２の連結部９２は、被覆部材２２から突出した支持軸１０８に嵌められた挿入孔１１０を有し、支持軸１０８を中心として回転自在であるように被覆部材２２に支持されている。第２の連結部９２は、挿入孔１１０のＸ方向両側に第１の腕部１１２と第２の腕部１１４が延びている。第１の腕部１１２には、第３の長穴１１６が形成されていると共に、第１の連結部９０には第３の突出部１２０が形成され、この第３の突出部１２０が第３の長穴１１６に挿入されて、第１の連結部９０と第２の連結部９２とが連結されている。また、第２の腕部１１４には第４の長穴１１８が形成されていると共に、第２の係止部７８には第４の突出部１２２が形成され、この第４の突出部１２２が第４の長穴１１８に挿入されている。第１の連結部９０がＺ方向に移動すると、第３の長穴１１６及び第３の突出部１２０を介して第２の連結部９２が支持軸１０８を中心として回転し、第４の長穴１１８及び第４の突出部１２２を介して、第２の係止部７８を第１の連結部９０の移動方向とは逆方向に移動させる。 As shown in FIG. 12, the second claw portion 84 of the second locking portion 78 is a second locked portion formed as a hole in the display device placement portion 86 provided on the image forming apparatus main body 12 side. It is locked to the portion 88. Further, as shown in FIGS. 6, 11 and 12, the second connecting portion 92 has an insertion hole 110 fitted into the support shaft 108 protruding from the covering member 22, and rotates about the support shaft 108. It is supported by the covering member 22 so as to be free. In the second connecting portion 92, a first arm portion 112 and a second arm portion 114 extend on both sides of the insertion hole 110 in the X direction. A third elongated hole 116 is formed in the first arm portion 112, and a third projecting portion 120 is formed in the first connecting portion 90. The third projecting portion 120 is the third projecting portion 120. The first connecting portion 90 and the second connecting portion 92 are connected to each other by being inserted into the slot 116 of the. Further, a fourth elongated hole 118 is formed in the second arm portion 114, and a fourth projecting portion 122 is formed in the second locking portion 78, and the fourth projecting portion 122 is formed. It is inserted in the fourth long hole 118. When the first connecting portion 90 moves in the Z direction, the second connecting portion 92 rotates about the support shaft 108 via the third elongated hole 116 and the third projecting portion 120, and the fourth elongated hole. The second locking portion 78 is moved in the direction opposite to the moving direction of the first connecting portion 90 via the 118 and the fourth protruding portion 122.

ここで、図６に示すように、挿入孔１１０の中心から第４の突出部１２２までの第２の腕部１１４の長さｄ１は、挿入孔１１０の中心から第３の突出部１２０の中心までの長さｄ２よりも常に長いようになっている。したがって、第１の連結部９０の移動距離よりも第２の係止部７８の移動距離が大きく、第２の係止部７８の係り止め及び係り止めの解除を確実に実行する。 Here, as shown in FIG. 6, the length d1 of the second arm 114 from the center of the insertion hole 110 to the fourth protrusion 122 is the center of the insertion hole 110 to the center of the third protrusion 120. It is always longer than the length d2. Therefore, the moving distance of the second locking portion 78 is longer than the moving distance of the first connecting portion 90, and the engagement and disengagement of the second engagement portion 78 is reliably performed.
