しかし、この種の読取装置では、開閉部の開放位置をヒンジのみで規制する構成となっており、本体部及び開閉部におけるヒンジの周辺やヒンジ自体の剛性を高くしなければ、ヒンジの周辺やヒンジ自体が破損する可能性がある。このため、この読取装置においては、ヒンジ周辺の高い耐久性を確保するために、軽量化及び小型化が損なわれたり、構造が複雑化して製造コストの高騰化を生じるおそれがある。 However, in this type of reading apparatus, the opening position of the opening / closing part is restricted only by the hinge, and if the rigidity of the hinge part or the hinge itself in the main body part and the opening / closing part is not increased, The hinge itself can be damaged. For this reason, in this reading apparatus, in order to ensure high durability around the hinge, there is a possibility that weight reduction and downsizing may be impaired, or the structure may be complicated, resulting in an increase in manufacturing cost.

本発明は、上記従来の実情に鑑みてなされたものであって、軽量化及び低コスト化を実現しつつ、高い耐久性を実現可能な読取装置を提供することを目的とする。 The present invention has been made in view of the above-described conventional situation, and an object thereof is to provide a reading apparatus capable of realizing high durability while realizing weight reduction and cost reduction.

本発明の読取装置は、読取対象の原稿を支持する原稿支持面が形成された本体部と、
前記本体部内に収容され、前記原稿支持面に支持された原稿の画像を読み取る読取部と、
前記本体部に対して前記原稿支持面における基準縁と平行に延びる揺動軸心周りで揺動可能に設けられ、前記原稿支持面を覆う閉鎖位置と、前記原稿支持面を露出させる開放位置とに変位可能な開閉部と、
前記本体部と前記開閉部との間に設けられ、前記揺動軸心を構成するヒンジとを備え、
前記本体部の上面には、前記揺動軸心に沿う方向の一端部に位置し、前記開閉部に向かって突出する第１突出部と、前記第１突出部と前記原稿支持面を挟んで前記揺動軸心に沿う方向の他端部に位置し、前記開閉部に向かって突出する第２突出部とが設けられ、
前記開閉部には、前記揺動軸心に沿う方向の一端部に位置し、前記閉鎖位置で前記第１突出部を収容する第１収容部と、前記揺動軸心に沿う方向の他端部に位置し、前記閉鎖位置で前記第２突出部を収容する第２収容部とが設けられ、
前記第１突出部と前記第１収容部との間には、前記開閉部の前記開放位置を規制する第１規制部が設けられ、
前記第２突出部と前記第２収容部との間には、前記開閉部の前記開放位置を規制する第２規制部が設けられていることを特徴とする。 The reading apparatus of the present invention includes a main body portion on which a document support surface for supporting a document to be read is formed,
A reading unit that is stored in the main body unit and reads an image of a document supported on the document support surface;
A closed position which is provided so as to be swingable about a swing axis extending in parallel with a reference edge on the document support surface with respect to the main body, and which covers the document support surface; and an open position where the document support surface is exposed. An openable / closable opening and
A hinge provided between the main body and the opening / closing portion and constituting the pivot axis;
The upper surface of the main body is located at one end in the direction along the pivot axis, and protrudes toward the opening / closing portion, and sandwiches the first protrusion and the document support surface. A second projecting portion located at the other end in the direction along the pivot axis and projecting toward the opening / closing portion;
The opening / closing portion is positioned at one end portion in the direction along the swing axis, and has a first storage portion for storing the first protrusion at the closed position, and the other end in the direction along the swing axis. And a second housing portion that houses the second projecting portion in the closed position,
Between the 1st protrusion part and the 1st storage part, the 1st regulation part which regulates the open position of the opening-and-closing part is provided,
A second restricting portion for restricting the open position of the opening / closing portion is provided between the second projecting portion and the second accommodating portion.

本発明の読取装置では、第１、２規制部が開閉部の開放位置を規制するので、従来の構成のように、ヒンジに対して、開放位置にある開閉部から過剰な力が作用することを抑制できる。また、この読取装置では、第１、２規制部が揺動軸心に沿って原稿支持面の両端に位置することとなる。このため、第１、２規制部がそれぞれ開放位置にある開閉部から受ける力は１／２ずつになる。よって、第１、２規制部も破損し難い。このため、高い耐久性を確保するために、本体部及び開閉部におけるヒンジの周辺やヒンジ自体の剛性を高くしなくても、ヒンジの周辺やヒンジ自体が破損することを抑制できる。 In the reading apparatus of the present invention, since the first and second restricting portions restrict the opening position of the opening / closing portion, excessive force acts on the hinge from the opening / closing portion in the opening position as in the conventional configuration. Can be suppressed. In this reading apparatus, the first and second restricting portions are positioned at both ends of the document support surface along the swing axis. For this reason, the force which the 1st, 2nd control part receives from the opening-and-closing part in an open position respectively becomes 1/2. Therefore, the first and second restricting portions are hardly damaged. For this reason, in order to ensure high durability, it is possible to prevent the periphery of the hinge and the hinge itself from being damaged without increasing the rigidity of the hinge and the hinge itself in the main body part and the opening / closing part.

したがって、本発明の読取装置では、軽量化及び低コスト化を実現しつつ、高い耐久性を実現可能である。 Therefore, in the reading apparatus of the present invention, high durability can be realized while realizing weight reduction and cost reduction.

また、この読取装置では、本体部から第１、２突出部が突出していても、開閉部の第１、２収容部が閉鎖位置で第１、２突出部を収容することから、第１、２突出部が開閉部とって邪魔になることはなく、開閉部は正しく閉鎖位置に変位可能である。 Further, in this reading apparatus, even if the first and second protrusions protrude from the main body, the first and second storage parts of the opening / closing part accommodate the first and second protrusions in the closed position. 2 The projecting portion does not get in the way of the opening / closing portion, and the opening / closing portion can be correctly displaced to the closed position.

第１規制部は開閉部の一端部における端縁近傍に設けられていることが好ましい。また、第２規制部は開閉部の他端部における端縁近傍に設けられていることが好ましい。そして、端縁近傍は、揺動軸心と平行な第一壁と、揺動軸心と直交する第二壁とが交差する部分を含むことが好ましい。この場合、開閉部の両端縁近傍は、それ以外の部分に対して剛性が高く、第１、２規制部が強固に開閉部を開放位置において規制することができる。 It is preferable that the 1st control part is provided in the edge vicinity in the one end part of an opening-and-closing part. Moreover, it is preferable that the 2nd control part is provided in the edge vicinity in the other end part of an opening-and-closing part. The vicinity of the end edge preferably includes a portion where a first wall parallel to the swing axis and a second wall orthogonal to the swing axis intersect. In this case, the vicinity of both end edges of the opening / closing part has higher rigidity than the other parts, and the first and second restricting parts can firmly restrict the opening / closing part at the open position.

第１規制部は、第１突出部の上端部から開放位置にある開閉部に向かって突出する第１当接片と、第１収容部に設けられ、開放位置において第１当接片と当接する第１被当接面とを含み得る。また、第２規制部は、第２突出部の上端部から開放位置にある開閉部に向かって突出する第２当接片と、第２収容部に設けられ、開放位置において第２当接片と当接する第２被当接面とを含み得る。この場合、第１、２規制部は、第１当接片と第１被当接面との当接と、第２当接片と第２被当接面との当接とにより、開放位置にある開閉部からの力を面で受けることができ、優れた耐久性を発揮する。 The first restricting portion is provided in the first abutting piece projecting from the upper end portion of the first projecting portion toward the opening / closing portion in the open position, and in the first accommodating portion, and is in contact with the first abutting piece in the open position. And a first abutted surface in contact therewith. The second restriction portion includes a second contact piece projecting toward the closing portion in the open position from the upper end portion of the second projecting portion, provided at the second yield capacity portion, a second contact in the open position And a second abutted surface that abuts the piece. In this case, the first and second restricting portions are opened by the contact between the first contact piece and the first contacted surface and the contact between the second contact piece and the second contacted surface. It can receive the force from the opening and closing part in the surface, and exhibits excellent durability.

本体部と開閉部との間には、閉鎖位置において、揺動軸心と平行な幅方向で本体部に対して開閉部を位置決めする第１位置決め部が設けられ得る。この第１位置決め部は、本体部における原稿支持面の外側周縁と、閉鎖位置において外側周縁に対向する開閉部との一方に形成され、突形状部に設けられる第１案内面と、本体部における原稿支持面の外側周縁と、閉鎖位置において外側周縁に対向する開閉部との他方に形成され、突形状部を収容する凹部を規定する第１被案内面とから構成され得る。そして、第１案内面と第１被案内面とは、開閉部を閉鎖位置に変位させることにより互いに当接することが好ましい。この場合、第１案内面と第１被案内面とにより、閉鎖位置において、開閉部を幅方向で位置決めすることができる。このため、開閉部を本体部に対して、幅方向に精度よく位置決めすることができ、外観の見栄えをよくすることができる。また、開閉部と本体部とが精度よく位置決めされることで、両者の間に隙間が生じることを抑制することができる。これにより、隙間からの外光の進入を低減させ、読取品質の低下を抑制することができる。 Between the main body part and the opening / closing part, a first positioning part for positioning the opening / closing part with respect to the main body part in a width direction parallel to the swing axis in the closed position may be provided. The first positioning portion is formed on one of an outer peripheral edge of the document supporting surface in the main body portion and an opening / closing portion facing the outer peripheral edge in the closed position, and a first guide surface provided on the projecting shape portion, It may be formed of an outer peripheral edge of the document support surface and a first guided surface that is formed on the other of the open / close portion facing the outer peripheral edge in the closed position and defines a concave portion that accommodates the protruding portion. And it is preferable that a 1st guide surface and a 1st to-be-guided surface mutually contact | abut by displacing an opening-and-closing part to a closed position. In this case, the opening / closing part can be positioned in the width direction at the closed position by the first guide surface and the first guided surface. For this reason, the opening / closing part can be accurately positioned in the width direction with respect to the main body part, and the appearance can be improved. Moreover, it can suppress that a clearance gap produces between both because an opening-and-closing part and a main-body part are positioned accurately. As a result, entry of external light from the gap can be reduced, and deterioration in reading quality can be suppressed.

前記第１突出部が前記第１被案内面を有し、前記第１収容部が前記第１案内面を有するか、前記第２突出部が前記第１被案内面を有し、前記第２収容部が前記第１案内面を有するか、又は、前記第１突出部及び前記第２突出部が前記第１被案内面を有し、前記第１収容部及び前記第２収容部が前記第１案内面を有していることが好ましい。この場合、ヒンジの開放位置を規制する第１、２規制部が第１位置決め部を兼ねるため、構成を簡略化することができる。また、原稿支持面の外側周縁に第１位置決め部材が別に設けられる場合に比べ、外側周縁を簡素化することができる。さらに、第１位置決め部が揺動軸心の近傍に設けられるため、ユーザが原稿支持面上に原稿を支持させる際に第１位置決め部が邪魔にならない。 The first protruding portion has the first guided surface, the first accommodating portion has the first guiding surface, or the second protruding portion has the first guided surface, and the second The accommodating part has the first guide surface, or the first projecting part and the second projecting part have the first guided surface, and the first accommodating part and the second accommodating part are the first It is preferable to have one guide surface . In this case, since the first and second restricting portions that restrict the opening position of the hinge also serve as the first positioning portion, the configuration can be simplified. Further, the outer peripheral edge can be simplified as compared with the case where the first positioning member is separately provided on the outer peripheral edge of the document support surface. Furthermore, since the first positioning portion is provided in the vicinity of the swing axis, the first positioning portion does not get in the way when the user supports the document on the document support surface.

第１案内面と第１被案内面との当接位置から本体部の上面までの距離と、揺動軸心から本体部の上面までの距離とが略等しいことが好ましい。 It is preferable that the distance from the contact position between the first guide surface and the first guided surface to the upper surface of the main body and the distance from the pivot axis to the upper surface of the main body are substantially equal.

この場合、開閉部が開放位置と閉鎖位置との間で揺動する際、第１案内面及び第１被案内面が揺動軸心に対して高低差を有して当接する場合に比べ、第１案内面と第１被案内面との摺動面積が小さくなる。このため、第１位置決め部を小型化できる。 In this case, when the opening / closing part swings between the open position and the closed position, compared to the case where the first guide surface and the first guided surface are in contact with the swing axis with a height difference. The sliding area between the first guide surface and the first guided surface is reduced. For this reason, a 1st positioning part can be reduced in size.

本体部と開閉部との間には、閉鎖位置において、揺動軸心と直交する前後方向で本体部に対して開閉部を位置決めする第２位置決め部が設けられ得る。この第２位置決め部は、本体部における原稿支持面の外側周縁と、閉鎖位置において外側周縁に対向する開閉部との一方に形成され、突形状部に設けられる第２案内面と、本体部における原稿支持面の外側周縁と、閉鎖位置において外側周縁に対向する開閉部との他方に形成され、突形状部を収容する凹部を規定する第２被案内面とから構成され得る。そして、第２案内面と第２被案内面とは、開閉部を閉鎖位置に変位させることにより互いに当接することが好ましい。この場合、第２案内面と第２被案内面とにより、閉鎖位置において、開閉部を前後方向で位置決めすることができる。このため、開閉部を本体部に対して、前後方向に精度よく位置決めすることができ、外観の見栄えをよくすることができる。また、開閉部と本体部とが精度よく位置決めされることで、両者の間に隙間が生じることを抑制することができる。これにより、隙間からの外光の進入を低減させ、読取品質の低下を抑制することができる。 Between the main body part and the opening / closing part, a second positioning part for positioning the opening / closing part with respect to the main body part in the front-rear direction orthogonal to the pivot axis in the closed position may be provided. The second positioning portion is formed on one of an outer peripheral edge of the document supporting surface in the main body portion and an opening / closing portion facing the outer peripheral edge in the closed position, and a second guide surface provided on the projecting shape portion, It may be formed of an outer peripheral edge of the document supporting surface and a second guided surface that is formed on the other of the open / close portion facing the outer peripheral edge at the closed position and defines a concave portion that accommodates the protruding portion. The second guide surface and the second guided surface are preferably in contact with each other by displacing the opening / closing portion to the closed position. In this case, the opening / closing part can be positioned in the front-rear direction at the closed position by the second guide surface and the second guided surface. For this reason, the opening / closing part can be accurately positioned in the front-rear direction with respect to the main body part, and the appearance can be improved. Moreover, it can suppress that a clearance gap produces between both because an opening-and-closing part and a main-body part are positioned accurately. As a result, entry of external light from the gap can be reduced, and deterioration in reading quality can be suppressed.

前記第１突出部が前記第２被案内面を有し、前記第１収容部が前記第２案内面を有するか、前記第２突出部が前記第２被案内面を有し、前記第２収容部が前記第２案内面を有するか、又は、前記第１突出部及び前記第２突出部が前記第２被案内面を有し、前記第１収容部及び前記第２収容部が前記第２案内面を有していることが好ましい。この場合、ヒンジの開放位置を規制する第１、２規制部が第２位置決め部を兼ねるため、構成を簡略化することができる。また、原稿支持面の外側周縁に第２位置決め部材が別に設けられる場合に比べ、外側周縁を簡素化することができる。さらに、第２位置決め部が揺動軸心の近傍に設けられるため、ユーザが原稿支持面上に原稿を支持させる際に、第２位置決め部が邪魔にならない。 The first protrusion has the second guided surface, the first accommodating portion has the second guide surface, or the second protrusion has the second guided surface, and the second The accommodating part has the second guide surface, or the first projecting part and the second projecting part have the second guided surface, and the first accommodating part and the second accommodating part are the first It is preferable to have two guide surfaces . In this case, since the first and second restricting portions that restrict the opening position of the hinge also serve as the second positioning portion, the configuration can be simplified. Further, the outer peripheral edge can be simplified as compared with the case where the second positioning member is separately provided on the outer peripheral edge of the document support surface. Further, since the second positioning portion is provided in the vicinity of the swing axis, the second positioning portion does not get in the way when the user supports the document on the document support surface.

第２案内面と第２被案内面との当接位置から本体部の上面までの距離と、揺動軸心から本体部の上面までの距離とが略等しいことが好ましい。 It is preferable that the distance from the contact position between the second guide surface and the second guided surface to the upper surface of the main body and the distance from the swing axis to the upper surface of the main body are substantially equal.

ここで、第２案内面と第２被案内面との当接は、第１案内面と第１被案内面との当接と同様であり得る。また、当接面、当接線又は当接点から本体部の上面までの距離も、第１案内面と第１被案内面との当接と同様に定義され得る。 Here, the contact between the second guide surface and the second guided surface may be the same as the contact between the first guide surface and the first guided surface. Further, the distance from the contact surface, the contact line, or the contact point to the upper surface of the main body can be defined in the same manner as the contact between the first guide surface and the first guided surface.

この場合、開閉部が開放位置と閉鎖位置との間で揺動する際、第２案内面及び第２被案内面が揺動軸心に対して高低差を有して当接する場合に比べ、第２案内面と第２被案内面との摺動面積が小さくなる。このため、第２位置決め部を小型化できる。 In this case, when the opening / closing part swings between the open position and the closed position, the second guide surface and the second guided surface are in contact with the swing axis with a height difference, compared with The sliding area between the second guide surface and the second guided surface is reduced. For this reason, a 2nd positioning part can be reduced in size.

第１突出部及び第２突出部は、揺動軸心に沿う方向から見て、読取部と重なる面を有することが好ましい。この場合、読取部に対して第１、２突出部が影を付与し、読取部への外光の進入を抑制することができる。 It is preferable that the first protrusion and the second protrusion have a surface that overlaps with the reading unit when viewed from the direction along the swing axis. In this case, the first and second protrusions can give a shadow to the reading unit, and the entry of external light to the reading unit can be suppressed.

第１突出部及び第２突出部は原稿支持面に隣接していることが好ましい。この場合、第１、２突出部は、原稿支持面上の読取対象の原稿が位置ずれすることを防止できる。 The first protrusion and the second protrusion are preferably adjacent to the document support surface. In this case, the first and second protrusions can prevent the document to be read on the document support surface from being displaced.

本発明の読取装置では、軽量化及び低コスト化を実現しつつ、高い耐久性を実現可能である。 In the reading apparatus of the present invention, high durability can be realized while realizing weight reduction and cost reduction.

＜作動＞
この複合機によって手動で薄い原稿の複写を行おうとする場合、まず、開閉部５をヒンジ１１、１３によって揺動軸心Ｘ周りで揺動させて開放位置とし、その原稿を本体部１の原稿支持面１５Ａに支持する。そして、開閉部５をヒンジ１１、１３によって揺動軸心Ｘ周りで揺動させて閉鎖位置とし、読取部３によってその原稿の画像を読み取ることが可能である。本体部１内では、シートが搬送部７によって搬送され、読み取られた画像が画像形成部９によって印刷され、排出される。こうして原稿の複写が完了する。 <Operation>
When a thin original is to be manually copied with this multifunction machine, first, the opening / closing part 5 is swung around the swing axis X by the hinges 11 and 13 to be in the open position, and the original is read from the main body 1. It is supported by the support surface 15A. The opening / closing unit 5 is swung around the swing axis X by the hinges 11 and 13 to be in the closed position, and the image of the original can be read by the reading unit 3. In the main body 1, the sheet is conveyed by the conveyance unit 7, and the read image is printed and discharged by the image forming unit 9. Thus, the copying of the original is completed.

この複合機によって手動で厚い原稿の複写を行おうとする場合、開閉部５を開放位置とし、その原稿を本体部１の原稿支持面１５Ａに支持した後、開閉部５を上昇位置に移動させつつ、閉鎖位置とする。この後、読取部３によってその原稿の画像を読み取ることが可能である。そして、同様に、原稿の複写が完了する。 When manually copying a thick original with this multifunction device, the opening / closing section 5 is set to the open position, and the original is supported on the original document supporting surface 15A of the main body section 1, and then the opening / closing section 5 is moved to the raised position. The closed position. Thereafter, the image of the original can be read by the reading unit 3. Similarly, the copy of the document is completed.

＜作用効果＞
従来の複合機では、開閉部５を開放位置に揺動する際、図７に示すヒンジ１１、１３の当接壁１１Ｅ、１３Ｅが開閉部５の内壁５Ｋと当接し、開閉部５の開放位置を規制する。この場合、開閉部５の開放位置をヒンジ１１、１３のみで規制するため、本体部１及び開閉部５におけるヒンジ１１、１３の周辺やヒンジ１１、１３自体が破損しないよう、ヒンジ１１、１３の周辺やヒンジ１１、１３自体の剛性を高くする必要がある。 <Effect>
In the conventional multifunction machine, when the opening / closing part 5 is swung to the open position, the contact walls 11E and 13E of the hinges 11 and 13 shown in FIG. To regulate. In this case, since the opening position of the opening / closing part 5 is restricted only by the hinges 11 and 13, the hinges 11 and 13 are prevented from being damaged in the vicinity of the hinges 11 and 13 and the hinges 11 and 13 themselves in the main body part 1 and the opening / closing part 5. It is necessary to increase the rigidity of the periphery and the hinges 11 and 13 themselves.

一方、実施例１の複合機では、開閉部５を開放位置に揺動する際、図９に示すように、第１、２突出部２１、２３から突出した第１、２当接片２２、２４の底面が第１、２被当接面２５Ａ、２７Ａと当接し、開閉部５の開放位置を規制する。このため、図７に示すように、ヒンジ１１、１３の当接壁１１Ｅ、１３Ｅは開閉部５の内壁５Ｋとの間に間隙Ｃを確保することができる。このため、ヒンジ１１、１３に対して開放位置にある開閉部５から過剰な力が作用することを抑制できる。 On the other hand, in the multifunction machine of the first embodiment, when the opening / closing part 5 is swung to the open position, as shown in FIG. 9, the first and second contact pieces 22 projecting from the first and second projecting parts 21 and 23, The bottom surface of 24 comes into contact with the first and second contact surfaces 25A and 27A and regulates the opening position of the opening / closing part 5. Therefore, as shown in FIG. 7, a gap C can be secured between the contact walls 11 E and 13 E of the hinges 11 and 13 and the inner wall 5 K of the opening / closing part 5. For this reason, it can suppress that excessive force acts on the hinges 11 and 13 from the opening-and-closing part 5 in an open position.

特に、この複合機では、第１、２被当接面２５Ａ、２７Ａが開閉部５における他の部分よりも剛性の高い両端部の端縁近傍に設けられているため、第１、２当接片２２、２４が強固に開放位置にある開閉部５を規制することができる。また、第１、２当接片２２、２４が大きな底面で第１、２被当接面２５Ａ、２７Ａと当接することから、面同士で当接することで、優れた耐久性を発揮する。 In particular, in this multi-function machine, the first and second contact surfaces 25A and 27A are provided in the vicinity of the edges of both end portions that are stiffer than the other portions of the opening / closing portion 5, so The opening / closing part 5 in which the pieces 22 and 24 are firmly in the open position can be regulated. In addition, since the first and second contact pieces 22 and 24 are in contact with the first and second contacted surfaces 25A and 27A at the large bottom surface, they are brought into contact with each other, thereby exhibiting excellent durability.

また、この複合機では、第１、２当接片２２、２４及び第１、２被当接面２５Ａ、２７Ａが揺動軸心Ｘに沿って原稿支持面１５Ａの両端に位置している。このため、第１、２当接片２２、２４及び第１、２被当接面２５Ａ、２７Ａがそれぞれ開放位置にある開閉部５から受ける力は１／２ずつになる。よって、第１、２当接片２２、２４及び第１、２被当接面２５Ａ、２７Ａが破損することを抑制できる。 Further, in this multifunction machine, the first and second contact pieces 22 and 24 and the first and second contact surfaces 25A and 27A are positioned along the swing axis X at both ends of the document support surface 15A. For this reason, the force which the 1st and 2nd contact pieces 22 and 24 and the 1st and 2nd contacted surfaces 25A and 27A receive from the opening / closing part 5 in the open position is halved. Therefore, it is possible to suppress the first and second contact pieces 22 and 24 and the first and second contact surfaces 25A and 27A from being damaged.

このため、この複合機では、高い耐久性を確保するために、本体部１及び開閉部５におけるヒンジ１１、１３の周辺やヒンジ１１、１３自体の剛性を高くしなくても、ヒンジ１１、１３の周辺やヒンジ１１、１３自体が破損することを抑制できる。 For this reason, in this multi-function machine, the hinges 11 and 13 can be secured without increasing the rigidity of the hinges 11 and 13 and the hinges 11 and 13 themselves in the main body 1 and the opening / closing part 5 in order to ensure high durability. Can be prevented from being damaged.

なお、この複合機では、当接壁１１Ｅ、１３Ｅで内壁５Ｋからの力を受けないことから、当接壁１１Ｅ、１３Ｅのあるヒンジ１１、１３を採用する必要がなく、また開閉部５が当接壁１１Ｅ、１３Ｅの近くに位置する内壁５Ｋを有する必要もない。このため、より簡易なヒンジ及び開閉部を採用し、よりコストダウンを図ることも可能である。 In this multi-function machine, the contact walls 11E and 13E do not receive the force from the inner wall 5K. Therefore, it is not necessary to use the hinges 11 and 13 having the contact walls 11E and 13E, and the opening / closing part 5 It is not necessary to have the inner wall 5K located near the contact walls 11E and 13E. For this reason, it is also possible to employ a simpler hinge and opening / closing part to further reduce the cost.

したがって、この複合機では、軽量化及び低コスト化を実現しつつ、高い耐久性を実現可能である。 Therefore, in this multifunction device, high durability can be realized while realizing weight reduction and cost reduction.

また、この複合機では、本体部１から第１、２突出部２１、２３が突出していても、開閉部５の第１、２収容部２５、２７が閉鎖位置で第１、２突出部２１、２３を収容することから、第１、２突出部２１、２３が開閉部５にとって邪魔になることはなく、開閉部５は正しく閉鎖位置に変位可能である。また、開閉部５を閉じた状態で、第１、２突出部２１、２３は外から見えない状態となり、外観を損ねることを防止できる。 Further, in this multifunction machine, even if the first and second protrusions 21 and 23 protrude from the main body 1, the first and second protrusions 21 are in the closed position when the first and second storage parts 25 and 27 of the opening / closing part 5 are closed. since housing the 23, never first and second projecting portions 21 and 23 gets in the way to take the opening portion 5, the opening and closing unit 5 is displaceable in the correctly closed position. Further, when the opening / closing part 5 is closed, the first and second protrusions 21 and 23 are invisible from the outside, and the appearance can be prevented from being damaged.

また、この複合機では、突形状部３１の外周面３１Ａと、凹部２９の左内面２９Ａ及び右内面２９Ｂとにより、閉鎖位置において、開閉部５を幅方向で位置決めすることができる。このため、開閉部５を本体部１に対して、幅方向に精度よく位置決めすることができ、外観の見栄えをよくすることができる。また、開閉部５と本体部１とが精度よく位置決めされることで、両者の間に隙間が生じることを抑制することができる。これにより、隙間からの外光の進入を低減させ、読取品質の低下を抑制することができる。 Further, in this multifunction machine, the opening / closing part 5 can be positioned in the width direction at the closed position by the outer peripheral surface 31A of the protruding portion 31 and the left inner surface 29A and the right inner surface 29B of the recess 29. For this reason, the opening / closing part 5 can be accurately positioned with respect to the main body part 1 in the width direction, and the appearance can be improved. Moreover, since the opening / closing part 5 and the main body part 1 are positioned with high accuracy, it is possible to suppress the occurrence of a gap between them. As a result, entry of external light from the gap can be reduced, and deterioration in reading quality can be suppressed.

また、この複合機では、突形状部３１の外周面３１Ａと、凹部２９の後内面２９Ｃとにより、閉鎖位置において、開閉部５を前後方向で位置決めすることもできる。このため、開閉部５を本体部１に対して、前後方向に精度よく位置決めすることができ、外観の見栄えをよくすることができる。また、開閉部５と本体部１とが精度よく位置決めされることで、両者の間に隙間が生じることを抑制することができる。これにより、隙間からの外光の進入を低減させ、読取品質の低下を抑制することができる。 Further, in this multifunction machine, the opening / closing part 5 can also be positioned in the front-rear direction at the closed position by the outer peripheral surface 31A of the protruding portion 31 and the rear inner surface 29C of the recess 29. For this reason, the opening / closing part 5 can be accurately positioned with respect to the main body part 1 in the front-rear direction, and the appearance can be improved. Moreover, since the opening / closing part 5 and the main body part 1 are positioned with high accuracy, it is possible to suppress the occurrence of a gap between them. As a result, entry of external light from the gap can be reduced, and deterioration in reading quality can be suppressed.

特に、この複合機では、第１、２突出部２１、２３が揺動軸心Ｘに沿う方向から見て、読取部３と重なる面を有しているため、読取部３に対して第１、２突出部２１、２３が影を付与し、読取部３への外光の進入を抑制することができる。 In particular, in this multi-function machine, the first and second protrusions 21 and 23 have a surface that overlaps the reading unit 3 when viewed from the direction along the swing axis X. The two projecting portions 21 and 23 can add a shadow and suppress the entry of external light to the reading unit 3.

（実施例２）
実施例２の複合機では、図１２（Ａ）に示すように、第１、２突出部２１、２３の第１、２当接片２２、２４に形成された穴３３を凹部として採用している。穴３３には、左内面３３Ａ及び右内面３３Ｂが形成されている。また、図１２（Ｂ）及び図１２（Ｃ）に示すように、穴３３に後内面３３Ｃが形成されている。左内面３３Ａ及び右内面３３Ｂが第１被案内面の一例であり、後内面３３Ｃが第２被案内面の一例である。 (Example 2)
In the multifunction machine of the second embodiment, as shown in FIG. 12 (A), the holes 33 formed in the first and second contact pieces 22 and 24 of the first and second protrusions 21 and 23 are employed as recesses. Yes. In the hole 33, a left inner surface 33A and a right inner surface 33B are formed. Further, as shown in FIGS. 12B and 12C, a rear inner surface 33 C is formed in the hole 33. The left inner surface 33A and the right inner surface 33B are an example of a first guided surface, and the rear inner surface 33C is an example of a second guided surface.

また、図１２（Ａ）に示すように、開閉部５に一対の突形状部３５が形成されている。突形状部３５の外周面３５Ａが第１、２案内面の一例である。 Further, as shown in FIG. 12A, a pair of protruding portions 35 are formed on the opening / closing portion 5. The outer peripheral surface 35A of the protruding portion 35 is an example of first and second guide surfaces.

第１、２当接片２２、２４及び突形状部３５が第１、２位置決め部に相当する。左内面３３Ａと外周面３５Ａとの当接位置は、左内面３３Ａが平坦面であり、外周面３５Ａが周面であることから、当接線として形成されている。この当接線から本体部１の上面までの距離を考える場合、当接線における本体部側の一端Ｃ１と、当接線の本体部１とは反対側となる他端Ｃ２との間で、揺動軸心Ｘを含んで本体部１の上面と平行な仮想面を定義する。図１２（Ａ）の例では、揺動軸心Ｘと他端Ｃ２とを含む仮想面Ｐ１を示している。この場合、当接線から本体部１の上面までの距離は、この仮想面Ｐ１と本体部１の上面との間の距離Ｌとして定義することができる。なお、この定義は一例にすぎず、本発明はこの定義に限定されない。図１２（Ａ）に示す例の場合、仮想面Ｐ１によって定義される当接線の基準位置から本体部１の上面までの距離Ｌ１と、揺動軸心Ｘから本体部１の上面までの距離Ｌ２とは略等しくなっている。また、図１２（Ａ）における揺動軸線Ｘと一端Ｃ１とを含む面を仮想面として定義した場合には、当接線の基準位置から本体部１の上面までの距離はＬ３になる。距離Ｌ３についても、距離Ｌ２と略等しいとする範囲に含まれるものとする。すなわち、仮想面によって定義される距離は、図１２の例では、距離Ｌ１から距離Ｌ３の範囲内に含まれるものであり、これらの距離は、距離Ｌ２と略等しい範囲とされる。なお、右内面３３Ｂと外周面３５Ａとの当接も当接線として形成されている。図１２（Ｂ）及び図１２（Ｃ）に示すように、後内面３３Ｃと外周面３５Ａとの当接も当接線として形成されている。これらの当接線と本体部１の上面までの距離との関係も上記した図１２（Ａ）の場合と同様に定義することができる。他の構成は実施例１の複合機と同様である。 The first and second contact pieces 22 and 24 and the projecting shape portion 35 correspond to the first and second positioning portions. Contact position between the left inner surface 33A and the outer peripheral surface 35A is left inside surface 33A is a flat surface, since the outer peripheral surface 35A is the circumferential surface is formed as a line of abutment. When considering the distance from the contact line to the upper surface of the main body 1, the swing axis is between the one end C 1 on the main body side of the contact line and the other end C 2 on the opposite side of the contact line from the main body 1. A virtual plane including the center X and parallel to the upper surface of the main body 1 is defined. In the example of FIG. 12A, a virtual plane P1 including the swing axis X and the other end C2 is shown. In this case, the distance from the contact line to the upper surface of the main body 1 can be defined as the distance L between the virtual plane P1 and the upper surface of the main body 1. This definition is merely an example, and the present invention is not limited to this definition. In the case of the example shown in FIG. 12A, the distance L1 from the reference position of the contact line defined by the virtual plane P1 to the upper surface of the main body 1 and the distance L2 from the swing axis X to the upper surface of the main body 1 Is almost equal. When the plane including the swing axis X and one end C1 in FIG. 12A is defined as a virtual plane, the distance from the reference position of the contact line to the upper surface of the main body 1 is L3. The distance L3 is also included in a range substantially equal to the distance L2. That is, the distance defined by the virtual plane is included in the range from the distance L1 to the distance L3 in the example of FIG. 12, and these distances are in a range substantially equal to the distance L2. The contact between the right inner surface 33B and the outer peripheral surface 35A is also formed as a contact line. As shown in FIGS. 12B and 12C, the contact between the rear inner surface 33C and the outer peripheral surface 35A is also formed as a contact line. The relationship between these contact lines and the distance to the upper surface of the main body 1 can also be defined as in the case of FIG. Other configurations are the same as those of the MFP of the first embodiment.

ここで、第１案内面と第１被案内面との当接、あるいは第２案内面と第２被案内面との当接は、面同士が当接することにより当接面として形成される場合、面と線、上記実施例１のように線同士で当接することにより当接線として形成される場合、面と点、線と点、あるいは点同士で当接することにより当接点として形成される場合等があり得る。例えば、当接面から本体部の上面までの距離を考える場合、当接面における本体部側の一端と、当接面における本体部とは反対側となる他端との間に、揺動軸心を含んで本体部の上面と平行な仮想面を定義する。そして、当接面から本体部の上面までの距離は、この仮想面と本体部上面との間の距離として定義することができる。同様に、当接線から本体部の上面までの距離を考える場合、当接線における本体部側の一端と、当接線の本体部とは反対側となる他端との間に、揺動軸心を含んで本体部の上面と平行な仮想面を定義する。そして、当接線から本体部の上面までの距離は、この仮想面と本体部の上面との間の距離として定義することができる。さらに、当接点については、当接点から本体部の上面に向けて鉛直方向に延ばした線が本体部の上面に到達するまでの距離として定義することができる。揺動軸心と本体部の上面までの距離は、揺動軸心と本体部上面との間の最短距離で定義することができる。 Here, the contact between the first guide surface and the first guided surface or the contact between the second guide surface and the second guided surface is formed as a contact surface by the surfaces contacting each other. When the surface is formed as a contact line by contacting the surface and the line, as in Example 1 above, the surface is formed as a contact point by contacting the surface and the point, the line and the point, or between the points And so on. For example, when considering the distance from the abutment surface to the upper surface of the main body, the swing shaft is provided between one end of the abutment surface on the main body portion side and the other end of the abutment surface opposite to the main body portion. A virtual plane including the heart and parallel to the upper surface of the main body is defined. The distance from the contact surface to the upper surface of the main body can be defined as the distance between the virtual surface and the upper surface of the main body. Similarly, when considering the distance from the contact line to the upper surface of the main body, the swing axis is set between one end of the contact line on the main body side and the other end of the contact line opposite to the main body. Including a virtual plane parallel to the upper surface of the main body. The distance from the contact line to the upper surface of the main body can be defined as the distance between the virtual surface and the upper surface of the main body. Furthermore, the contact point can be defined as a distance until a line extending in the vertical direction from the contact point toward the upper surface of the main body reaches the upper surface of the main body. The distance between the swing axis and the upper surface of the main body can be defined as the shortest distance between the swing axis and the upper surface of the main body.

この複合機では、ヒンジ１１、１３の開放位置を規制する第１、２当接片２２、２４が第１、２位置決め部を兼ねるため、構成を簡略化することができる。また、原稿支持面１５Ａの外側周縁に第１、２位置決め部材が別に設けられる場合に比べ、外側周縁を簡素化することができる。さらに、第１、２当接片２２、２４が揺動軸心Ｘの近傍、すなわち原稿支持面１５Ａから離れた位置に設けられるため、ユーザが原稿支持面１５Ａ上に原稿を支持させる際に、第１、２位置決め部が邪魔にならない。 In this multi-function machine, the first and second contact pieces 22 and 24 that regulate the opening positions of the hinges 11 and 13 also serve as the first and second positioning portions, so that the configuration can be simplified. Further, the outer periphery can be simplified as compared with the case where the first and second positioning members are separately provided on the outer periphery of the document support surface 15A. Further, since the first and second contact pieces 22 and 24 are provided in the vicinity of the swing axis X, that is, at a position away from the document support surface 15A, when the user supports the document on the document support surface 15A, The first and second positioning parts do not get in the way.

また、この複合機では、左内面３３Ａ、右内面３３Ｂ及び後内面３３Ｃと外周面３５Ａとの当接線から本体部１の上面までの距離と、揺動軸心Ｘから本体部１の上面までの距離Ｌとが略等しく離間している。このため、開閉部５の開閉に伴う突形状部３５の移動軌跡が小さくなり、突形状部３５を収容する穴３３も小さくできる。このため、実施例１の複合機のように、前後に長い凹部２９を採用する必要がない。逆に、穴３３が小さくてよいため、第１、２当接片２２、２４にその穴３３を形成することができる。他の作用効果は実施例１の複合機と同様である。 Further, in this multi-function machine, the distance from the contact line between the left inner surface 33A, the right inner surface 33B, the rear inner surface 33C and the outer peripheral surface 35A to the upper surface of the main body 1 and from the swing axis X to the upper surface of the main body 1 The distance L is substantially equal to each other. For this reason, the movement locus | trajectory of the protrusion-shaped part 35 accompanying opening / closing of the opening / closing part 5 becomes small, and the hole 33 which accommodates the protrusion-shaped part 35 can also be made small. For this reason, it is not necessary to employ the long concave portion 29 in the front and rear as in the multifunction machine of the first embodiment. Conversely, since the hole 33 may be small, the hole 33 can be formed in the first and second contact pieces 22, 24. Other functions and effects are the same as those of the multifunction machine of the first embodiment.

（実施例３）
実施例３の複合機では、図１３に示すように、第１、２突出部３７、３９が原稿支持面１５Ａに隣接している。他の構成は実施例１、２の複合機と同様である。 (Example 3)
In the multifunction machine according to the third embodiment, as shown in FIG. 13, the first and second protrusions 37 and 39 are adjacent to the document support surface 15A. Other configurations are the same as those of the MFPs of the first and second embodiments.

この複合機では、第１、２突出部３７、３９が原稿支持面１５Ａに隣接しているため、第１、２突出部３７、３９は、原稿支持面１５Ａ上の読取対象の原稿が位置ずれすることを防止できる。他の作用効果は実施例１、２の複合機と同様である。 In this multifunction device, since the first and second protrusions 37 and 39 are adjacent to the document support surface 15A, the first and second protrusions 37 and 39 are misaligned with the document to be read on the document support surface 15A. Can be prevented. Other functions and effects are the same as those of the MFPs of the first and second embodiments.

以上において、本発明を実施例１〜３に即して説明したが、本発明は上記実施例１〜３に制限されるものではなく、その趣旨を逸脱しない範囲で適宜変更して適用できることはいうまでもない。 In the above, the present invention has been described with reference to the first to third embodiments. However, the present invention is not limited to the first to third embodiments, and can be appropriately modified and applied without departing from the spirit of the present invention. Needless to say.

例えば、実施例１〜３では、第１位置決め部と第２位置決め部とを兼ねているが、これらを別々にすることも可能である。また、第１、２当接片２２、２４は、開放位置にある開閉部５に当接して、位置を規制することが可能であれば、この形状に限定されるものではない。 For example, in the first to third embodiments, the first positioning portion and the second positioning portion are also used. Moreover, the 1st, 2nd contact pieces 22 and 24 will not be limited to this shape, if it can contact | abut to the opening-and-closing part 5 in an open position, and can control a position.

本発明は複合機等に利用可能である。 The present invention can be used for a multifunction machine or the like.
