Description

本発明は、画像形成装置、画像読取装置、複合機及び載置台に関するものである。   The present invention relates to an image forming apparatus, an image reading apparatus, a multifunction peripheral, and a mounting table.

従来、原稿に記された画像を読み取って、読み取った画像を記録用紙に形成する画像形成装置が多数開発され実用化に至っている。この画像形成装置は、画像を読み取る画像読取部と、画像読取部の下方に配置され且つ画像読取部が読み取った画像を記録用紙に形成する画像形成部と、画像読取部が上面に載置される載置台と、を備えて構成されている(特許文献1参照)。   Conventionally, many image forming apparatuses that read an image written on a document and form the read image on a recording sheet have been developed and put to practical use. In this image forming apparatus, an image reading unit that reads an image, an image forming unit that is disposed below the image reading unit and that forms an image read by the image reading unit on a recording sheet, and an image reading unit are mounted on an upper surface. And a mounting table (see Patent Document 1).

特許文献1に記載の載置台は、画像形成部の上方に配置され且つ上下移動自在な台座部材と、上下方向に伸縮自在に構成され且つ前記台座部材を上方に向けて付勢する付勢部材と、台座部材が上下移動した位置で固定するロック機構と、ロック機構のロックを解除可能な解除機構と、を有している。なお、付勢部材は、画像読取部の重量と略等しい上向きの力を台座部材に付与している。   A mounting table described in Patent Document 1 is a pedestal member that is disposed above an image forming unit and is movable up and down, and an urging member that is configured to expand and contract in the vertical direction and urges the pedestal member upward. And a lock mechanism that fixes the pedestal member at a position where it moves up and down, and a release mechanism that can release the lock of the lock mechanism. The biasing member applies an upward force substantially equal to the weight of the image reading unit to the pedestal member.

そして、画像形成部の内部で紙詰まりなどの不具合が発生したときや、消耗品の交換などのメンテナンスが必要なときには、解除機構を操作してロック機構のロックを解除し、画像読取部を載置した状態で台座部材を上方に移動させてから、用紙除去作業やメンテナンス作業を行っている。   When a problem such as a paper jam occurs inside the image forming unit, or when maintenance such as replacement of consumables is required, the unlocking mechanism is operated to unlock the locking mechanism, and the image reading unit is mounted. After the pedestal member is moved upward in the placed state, the sheet removing operation and the maintenance operation are performed.

特開平9−218552号公報Japanese Patent Laid-Open No. 9-218552

ところが、従来の画像形成装置では、画像読取部が台座部材に載置されていない状態で、解除機構を操作してロック機構のロックを解除すると、付勢部材の付勢力により台座部材が上方に向かって急激に飛び上がり、載置台の一部に無理な力が加わるため、載置台の一部が損傷する虞があった。   However, in the conventional image forming apparatus, when the unlocking mechanism is operated and the lock mechanism is unlocked in a state where the image reading unit is not placed on the base member, the base member is moved upward by the biasing force of the biasing member. Since it suddenly jumps up and an excessive force is applied to a part of the mounting table, there is a possibility that a part of the mounting table is damaged.

本発明はこのような観点から創案されたものであり、台座部材の急激な飛び上がりを回避して、載置台の一部の損傷を防止できる画像形成装置を提供することを課題とする。   The present invention has been invented from such a viewpoint, and it is an object of the present invention to provide an image forming apparatus that can avoid a sudden jump of a pedestal member and prevent a part of the mounting table from being damaged.

前記課題を解決するため本発明は、原稿に記された画像を読み取る画像読取部と、前記画像読取部が読み取った読取画像を媒体に形成する画像形成部と、前記画像読取部が上面に載置される載置台と、を備えた画像形成装置であって、前記載置台は、前記画像形成部の上方に配置され、上下移動自在な台座部材と、上下方向に伸縮自在に構成され、前記台座部材を上方に向けて付勢する付勢部材と、前記付勢部材を上下方向に伸縮自在に支持する支持部材と、前記台座部材が上下移動した位置で固定するロック機構と、前記ロック機構のロックを解除可能な解除機構と、前記画像読取部が前記台座部材上に載置された状態で前記解除機構の解除を許容する係止機構と、を有することを特徴とする。   In order to solve the above problems, the present invention provides an image reading unit that reads an image written on a document, an image forming unit that forms a read image read by the image reading unit on a medium, and the image reading unit on an upper surface. An image forming apparatus comprising: a mounting table, wherein the mounting table is disposed above the image forming unit, and is configured to be vertically movable and extendable in the vertical direction; An urging member that urges the base member upward, a support member that supports the urging member in an up-and-down direction, a lock mechanism that fixes the pedestal member at a position in which the base member has moved up and down, and the lock mechanism A release mechanism that can release the lock, and a locking mechanism that allows the release mechanism to be released in a state where the image reading unit is placed on the pedestal member.

本発明によれば、画像読取部が台座部材上に載置された状態で解除機構の解除動作を許容する係止機構を設けたことにより、画像読取部が台座部材上に載置されていない状態ではロック機構のロックを解除できないため、付勢部材により台座部材が上方に向かって急激に飛び上がるのを回避できる。したがって、載置台の一部に無理な力が加わらないため、載置台の一部の損傷を防止できる。   According to the present invention, the image reading unit is not placed on the pedestal member by providing the locking mechanism that allows the release operation of the release mechanism while the image reading unit is placed on the pedestal member. Since the lock mechanism cannot be unlocked in the state, the urging member can avoid the base member from rapidly jumping upward. Therefore, since an excessive force is not applied to a part of the mounting table, a part of the mounting table can be prevented from being damaged.

本発明によれば、台座部材の急激な飛び上がりを回避して、載置台の一部の損傷を防止できる画像形成装置を提供することができる。   According to the present invention, it is possible to provide an image forming apparatus capable of avoiding a sudden jump of the pedestal member and preventing a part of the mounting table from being damaged.

As shown in FIGS. 7 and 8, one end of the cable 57 is fixed to the engaging member 55 b of the lock mechanism 55 via the connecting portion 57 a, and the other end is fixed to the lock plate 56 a of the release mechanism 56.

図9は、台座部材を示す斜視図のX−X線断面図である。
係止機構58は、画像読取装置1が台座部材51上に載置されていない状態で解除機構56の解除動作を規制すると共に、画像読取装置1が台座部材51上に載置された状態で解除機構56の解除動作を許容する機能を有している。係止機構58は、図8に示すように、ベース部材58aと、ベース部材58a上に固定された弾性部材58bと、弾性部材58b上に固定されたストッパ部材58cと、ストッパ部材58c上に固定された平板状の緩衝部材58dと、を有している。
FIG. 9 is a cross-sectional view taken along line XX of the perspective view showing the base member.
The locking mechanism 58 regulates the release operation of the release mechanism 56 in a state where the image reading device 1 is not placed on the pedestal member 51, and in a state where the image reading device 1 is placed on the pedestal member 51. The release mechanism 56 has a function of allowing the release operation. As shown in FIG. 8, the locking mechanism 58 includes a base member 58a, an elastic member 58b fixed on the base member 58a, a stopper member 58c fixed on the elastic member 58b, and fixed on the stopper member 58c. And a flat plate-shaped buffer member 58d.

ベース部材58aは、図9に示すように、薄板状を呈する金属材から成り、カバー部51bに固定されている。
弾性部材58bは、例えばバネ部材などから成り、上下方向に伸縮自在に構成されており、ストッパ部材58cを上方に向かって付勢している。
As shown in FIG. 9, the base member 58a is made of a thin metal material and is fixed to the cover portion 51b.
The elastic member 58b is made of, for example, a spring member and is configured to be extendable in the vertical direction, and urges the stopper member 58c upward.

ストッパ部材58cは、画像読取装置1が台座部材51上に載置されていない状態で、ロックプレート56aのロック解除位置への移動を規制する邪魔部材として機能する。ストッパ部材58cは、図8に示すように、薄板状を呈する金属材の周縁を下方に折り曲げて形成されている。ストッパ部材58cの支持プレート56f側の端部には、他の部分よりも後方に向かって張り出す当接部58eが形成されている。   The stopper member 58c functions as a baffle member that restricts the movement of the lock plate 56a to the unlock position when the image reading apparatus 1 is not placed on the pedestal member 51. As shown in FIG. 8, the stopper member 58c is formed by bending the periphery of a thin metal material downward. At the end of the stopper member 58c on the support plate 56f side, an abutting portion 58e that protrudes rearward from the other portion is formed.

当接部58eは、図9に示すように、画像読取装置1が台座部材51上に載置されていない状態において、ロックプレート56aの係止片56dと当接している。

本実施形態に係る複合機100は、基本的には以上のように構成されるものであり、次に、図1乃至図10を適宜参照して、本実施形態に係る複合機100の動作及び作用効果について説明する。図10は、係止機構の動作を説明するための説明図である。   The MFP 100 according to the present embodiment is basically configured as described above. Next, referring to FIGS. 1 to 10 as appropriate, the operation of the MFP 100 according to the present embodiment and The effect will be described. FIG. 10 is an explanatory diagram for explaining the operation of the locking mechanism.

初めに、図10(a)に示すように、画像読取装置1の凸部1aと載置台5の位置決め孔51dの上下位置を合わせつつ、載置台5の上方から画像読取装置1を下方に降ろす。なお、初期状態では、係止機構58のストッパ部材58cがロックプレート56aの係止片56dに当接しているので、ロックプレート56aのロック解除位置への移動が阻まれており、解除機構56によりロック機構55のロックを解除することができない。   First, as shown in FIG. 10A, the image reading device 1 is lowered from above the mounting table 5 while aligning the vertical positions of the convex portions 1 a of the image reading device 1 and the positioning holes 51 d of the mounting table 5. . In the initial state, since the stopper member 58c of the locking mechanism 58 is in contact with the locking piece 56d of the lock plate 56a, the movement of the lock plate 56a to the unlocking position is prevented, and the releasing mechanism 56 The lock of the lock mechanism 55 cannot be released.

続いて、図10(b)及び(c)に示すように、画像読取装置1の凸部1aが、載置台5の位置決め孔51dを通じて緩衝部材58d上に載置されると、画像読取装置1の重量により弾性部材58bは下向きに押圧される。これにより、弾性部材58bが下方に向かって収縮する。   Subsequently, as shown in FIGS. 10B and 10C, when the convex portion 1 a of the image reading device 1 is placed on the buffer member 58 d through the positioning hole 51 d of the placing table 5, the image reading device 1. Due to the weight of the elastic member 58b, the elastic member 58b is pressed downward. As a result, the elastic member 58b contracts downward.

図10(d)に示すように、弾性部材58bが下方に向かって収縮すると、ストッパ部材58c及び緩衝部材58dが下方に向かって移動する。このとき、ストッパ部材58cの上面58f及び緩衝部材58dの上面58gが、ロックプレート56aの係止片56dの下面56kより下方に位置するため、ロックプレート56aのロック解除位置(矢印A方向)への移動が許容される。なお、画像読取装置1の凸部1aは、ロックプレート56aの移動方向において係止片56dと重ならない位置で、緩衝部材58dを押圧するため、ロックプレート56aのロック解除位置への移動を妨げない。   As shown in FIG. 10D, when the elastic member 58b contracts downward, the stopper member 58c and the buffer member 58d move downward. At this time, since the upper surface 58f of the stopper member 58c and the upper surface 58g of the buffer member 58d are located below the lower surface 56k of the locking piece 56d of the lock plate 56a, the lock plate 56a is moved to the unlocked position (arrow A direction). Movement is allowed. Note that the convex portion 1a of the image reading apparatus 1 presses the buffer member 58d at a position where it does not overlap the locking piece 56d in the moving direction of the lock plate 56a, so that the movement of the lock plate 56a to the unlock position is not hindered. .

そして、図8(b)に示すように、操作部材56bを前方方向(矢印B方向)へ回転させると、操作部材56bの押圧部56jがロックプレート56aの掛止孔56cを押圧して、ロックプレート56aが解除位置へ移動する。なお、ロックプレート56aが解除位置へ移動すると、ロックプレート56aに固定されたケーブル57が引っ張られ、ロック機構55の係合部材55bが被係合部材55aから外れて、台座部材51の上下移動が可能になる。   Then, as shown in FIG. 8 (b), when the operating member 56b is rotated in the forward direction (arrow B direction), the pressing portion 56j of the operating member 56b presses the latching hole 56c of the lock plate 56a to lock the operating member 56b. The plate 56a moves to the release position. When the lock plate 56a moves to the release position, the cable 57 fixed to the lock plate 56a is pulled, the engagement member 55b of the lock mechanism 55 is disengaged from the engaged member 55a, and the pedestal member 51 is moved up and down. It becomes possible.

続いて、操作者が台座部材51を上方に向かって持ち上げると、図2に示すように、付勢部材53が伸長すると共に、付勢部材53に固定された保持部材52及び保持部材52に固定された台座部材51が上方に向かって移動する。さらに、図5に示すように、ロック機構55の係合部材55bが被係合部材55aに係合すると、台座部材51が上方位置で固定される。   Subsequently, when the operator lifts the pedestal member 51 upward, as shown in FIG. 2, the urging member 53 extends and is fixed to the holding member 52 and the holding member 52 fixed to the urging member 53. The base member 51 thus moved moves upward. Further, as shown in FIG. 5, when the engaging member 55b of the lock mechanism 55 is engaged with the engaged member 55a, the base member 51 is fixed at the upper position.

以上説明した第1実施形態によれば、画像読取装置1が台座部材51上に載置された状態で解除機構56の解除動作を許容する係止機構58を設けたことにより、画像読取装置1が台座部材51上に載置されていない状態ではロック機構55のロックを解除することができないため、付勢部材53により台座部材51が上方に向かって急激に飛び上がるのを回避できる。したがって、載置台5の一部(例えば案内部材52cなど)に無理な力が加わらないため、載置台5の一部の損傷を防止できる。   According to the first embodiment described above, the image reading apparatus 1 is provided by providing the locking mechanism 58 that allows the releasing operation of the releasing mechanism 56 while the image reading apparatus 1 is placed on the pedestal member 51. However, since the lock mechanism 55 cannot be unlocked when it is not placed on the base member 51, the biasing member 53 can prevent the base member 51 from jumping rapidly upward. Therefore, since an excessive force is not applied to a part of the mounting table 5 (for example, the guide member 52c), damage to a part of the mounting table 5 can be prevented.

《第2実施形態》
次に、図11乃至図13を参照して、本発明の第2実施形態に係る複合機について説明する。第2実施形態に係る複合機の説明においては、第1実施形態に係る複合機100と重複する部分については、説明を省略する。
<< Second Embodiment >>
Next, a multifunction peripheral according to a second embodiment of the present invention will be described with reference to FIGS. In the description of the multifunction peripheral according to the second embodiment, the description of the same parts as those of the multifunction peripheral 100 according to the first embodiment is omitted.

図11は、本発明の第2実施形態に係る複合機の載置台及び載置台係止機構を示す斜視図である。図12は、載置台係止機構を示す斜視図である。図13は、載置台係止機構の動作を説明するための説明図である。本実施形態は、載置台係止機構7が設けられている点が、前記した第1実施形態と異なる。   FIG. 11 is a perspective view showing a mounting table and a mounting table locking mechanism of the multifunction machine according to the second embodiment of the present invention. FIG. 12 is a perspective view showing the mounting table locking mechanism. FIG. 13 is an explanatory diagram for explaining the operation of the mounting table locking mechanism. This embodiment is different from the first embodiment described above in that the mounting table locking mechanism 7 is provided.

載置台係止機構7は、画像読取装置1が台座部材51上に載置されていない状態で台座部材51を支持部材54に係止すると共に、画像読取装置1が台座部材51上に載置された状態で台座部材51の支持部材54に対する相対的な移動を許容する機能を有している。載置台係止機構7は、図11に示すように、一対のカバー部51bのうち一方のカバー部51bの後端部に取り付けられている。載置台係止機構7は、図12及び図13に示すように、基部材71と、弾性部材72と、被押圧部材73と、係止部材74と、連結部材75と、を有している。   The mounting table locking mechanism 7 locks the pedestal member 51 to the support member 54 in a state where the image reading device 1 is not mounted on the pedestal member 51, and the image reading device 1 is mounted on the pedestal member 51. In this state, the base member 51 has a function of permitting relative movement with respect to the support member 54. As shown in FIG. 11, the mounting table locking mechanism 7 is attached to the rear end portion of one cover portion 51b of the pair of cover portions 51b. As shown in FIGS. 12 and 13, the mounting table locking mechanism 7 includes a base member 71, an elastic member 72, a pressed member 73, a locking member 74, and a connecting member 75. .

基部材71は、係止部材74を支持するための部材であり、支軸71aを支点として回転可能にカバー部51bに固定されている。基部材71は、図12に示すように、一枚の金属板の両端を下方に折り曲げて形成されている。基部材71の後方寄り(縦枠54b側)の端部には、矩形状の固定孔71bが板厚方向に貫通して形成されている。   The base member 71 is a member for supporting the locking member 74, and is fixed to the cover portion 51b so as to be rotatable about the support shaft 71a. As shown in FIG. 12, the base member 71 is formed by bending both ends of a single metal plate downward. A rectangular fixing hole 71b is formed at the end of the base member 71 closer to the rear (on the vertical frame 54b side) so as to penetrate in the plate thickness direction.

弾性部材72は、図13に示すように、基部材71を係止孔54f側(斜め後方)に向かって付勢する部材であり、例えばバネ部材などで構成されている。弾性部材72は、基部材71内に配置されている。   As shown in FIG. 13, the elastic member 72 is a member that urges the base member 71 toward the locking hole 54 f side (diagonally rearward), and is formed of, for example, a spring member. The elastic member 72 is disposed in the base member 71.

被押圧部材73は、図12及び図13に示すように、側面視略ロ形状を呈しており、画像形成部3の凸部1aに押圧される部材である。被押圧部材73は、基部材71の上面に固定され、初期状態では台座部材51の位置決め孔51dから突出している。被押圧部材73の上面73aは、前方に向かうにつれて下方に傾斜するように形成されている。かかる構成により、被押圧部材73の上面73aの後方寄りの部分が、画像形成部3の凸部1aとはじめに接触するため、基部材71が係止孔54fと反対側(斜め前方)に回転しやすくなる。   As shown in FIGS. 12 and 13, the pressed member 73 has a substantially rectangular shape when viewed from the side, and is a member that is pressed by the convex portion 1 a of the image forming unit 3. The pressed member 73 is fixed to the upper surface of the base member 71, and protrudes from the positioning hole 51 d of the base member 51 in the initial state. The upper surface 73a of the pressed member 73 is formed so as to incline downward toward the front. With this configuration, the portion closer to the rear of the upper surface 73a of the pressed member 73 contacts the convex portion 1a of the image forming unit 3 at the beginning, so the base member 71 rotates to the opposite side (obliquely forward) from the locking hole 54f. It becomes easy.

係止部材74は、図13に示すように、側面視略L字状を呈しており、その先端が支持部材54の縦枠54bに形成された係止孔54fに挿入され、基端が連結部材75を介して基部材71に固定されている。   As shown in FIG. 13, the locking member 74 has a substantially L shape in a side view, and its distal end is inserted into a locking hole 54 f formed in the vertical frame 54 b of the support member 54, and the base end is connected. It is fixed to the base member 71 via a member 75.

連結部材75は、図12に示すように、円柱状を呈しており、係止部材74を基部材71に連結するための部材である。連結部材75は、係止部材74に貫通した状態で取り付けられ、その両端が基部材71の固定孔71bに挿通されている。   As shown in FIG. 12, the connecting member 75 has a columnar shape and is a member for connecting the locking member 74 to the base member 71. The connecting member 75 is attached so as to penetrate the locking member 74, and both ends thereof are inserted into the fixing holes 71 b of the base member 71.

本実施形態に係る複合機100は、基本的には以上のように構成されるものであり、次に、図12を参照して、本実施形態に係る複合機100の載置台係止機構7の動作及び作用効果について説明する。   The MFP 100 according to the present embodiment is basically configured as described above. Next, with reference to FIG. 12, the mounting table locking mechanism 7 of the MFP 100 according to the present embodiment. The operation and effect of the will be described.

初めに、図13(a)に示すように、画像読取装置1の凸部1aと載置台5の位置決め孔51dの上下位置を合わせつつ、載置台5の上方から画像読取装置1を下方に降ろす。なお、初期状態では、載置台係止機構7の係止部材74が縦枠54bの係止孔54fに挿入されているので、解除機構56でロック機構55のロックを解除して、台座部材51を上方に向かって持ち上げようとしても、係止部材74が係止孔54fに引っ掛かり、台座部材51を上方に移動させることができない。   First, as shown in FIG. 13A, the image reading apparatus 1 is lowered from above the mounting table 5 while aligning the vertical positions of the convex portions 1 a of the image reading apparatus 1 and the positioning holes 51 d of the mounting table 5. . In the initial state, since the locking member 74 of the mounting table locking mechanism 7 is inserted into the locking hole 54f of the vertical frame 54b, the lock mechanism 55 is unlocked by the release mechanism 56, and the pedestal member 51 is released. Even if it is going to be lifted upward, the locking member 74 is caught in the locking hole 54f, and the base member 51 cannot be moved upward.

続いて、図13(b)に示すように、画像読取装置1が載置台5上に載置されると、画像読取装置1の凸部1aが載置台係止機構7の被押圧部材73に当接する共に、画像読取装置1の重量により基部材71は斜め前方に押圧される。これにより、基部材71は、支軸71aを支点にして前端側が上を向くように回転する。   Subsequently, as shown in FIG. 13B, when the image reading device 1 is placed on the mounting table 5, the convex portion 1 a of the image reading device 1 is applied to the pressed member 73 of the mounting table locking mechanism 7. At the same time, the base member 71 is pushed obliquely forward by the weight of the image reading apparatus 1. Thereby, the base member 71 rotates so that the front end side faces upward with the support shaft 71a as a fulcrum.

基部材71が回転すると、係止部材74が縦枠54bの係止孔54fから抜け出し、台座部材51及び保持部材52が上方に移動可能になると共に、付勢部材53の上方への伸長が可能になる。   When the base member 71 rotates, the locking member 74 comes out of the locking hole 54f of the vertical frame 54b, the base member 51 and the holding member 52 can move upward, and the biasing member 53 can extend upward. become.

以上説明した第2実施形態によれば、画像読取装置1が台座部材51上に載置された状態で台座部材51の上方移動を許容する載置台係止機構7を設けたことにより、画像読取装置1が台座部材51上に載置されていない状態では、台座部材51及び保持部材52の上方移動や付勢部材53の上方への伸長が抑止される。したがって、付勢部材53により台座部材51が上方に向かって急激に飛び上がるのを回避することが可能となり、載置台5の一部(例えば案内部材52c)に無理な力が加わらないため、載置台5の一部の損傷を防止できる。   According to the second embodiment described above, the image reading apparatus 1 is provided with the mounting table locking mechanism 7 that allows the base member 51 to move upward in a state where the image reading device 1 is mounted on the base member 51. In a state where the device 1 is not placed on the pedestal member 51, the upward movement of the pedestal member 51 and the holding member 52 and the upward extension of the biasing member 53 are suppressed. Therefore, the urging member 53 can avoid the base member 51 from rapidly jumping upward, and an excessive force is not applied to a part of the mounting table 5 (for example, the guide member 52c). 5 can be prevented from being damaged.

以上、本発明の実施形態について図面を参照して詳細に説明したが、本発明はこれに限定されるものではなく、発明の主旨を逸脱しない範囲で適宜変更可能である。
