Description

  The present invention relates to a composite printing apparatus that includes a first casing and a second casing that is supported by the first casing and rotates so as to open and close the upper side of the first casing, and that prints an image on a sheet.

  In many of the composite printing apparatuses as described above, a printing unit that prints an image on a recording sheet is mounted on the first casing, and a scanner unit that reads an image to be printed on the recording sheet from a document is mounted on the second casing. Is done. When a recording sheet on which an image is printed by the printing unit is jammed inside the first casing, the user of the multifunction peripheral can close the first casing from the closed position that covers the upper side of the first casing. The jammed recording sheet can be taken out by rotating the upper side of the body to the open posture.

  In addition, the composite printing apparatus usually has a posture that stands up along the side surface of the device, but is provided with a rotation member that can be rotated from the side surface to a posture inclined outward as needed. There may be. An example of such a rotating member is a manual feed tray that is often provided in a composite printing apparatus. The manual feed tray is rotated from a standing position to a tilted position when used, and a recording sheet is placed on the upper surface.

  And the above rotation members may be provided in the 2nd case. Patent Document 1 discloses an image recording apparatus in which a manual feed tray as an example of a rotating member is provided in a scanner reading unit as an example of a second housing.

JP2012-001329A

  However, when the rotating member is provided in the second housing, the problem described below occurs. That is, when the second casing is rotated from the closed position to the open position, the rotating member provided in the second casing is also rotated integrally with the second casing. At this time, if the rotation member is tilted, the rotation tip of the rotation member is positioned below the expected position. As a result, there is a possibility that a material placed on the rotating member (for example, a recording sheet when the rotating member is a manual feed tray) may fall from the manual feed tray.

  The present invention has been made in view of the above problems, and its object is to provide a support by rotating the housing when the support member that supports the supported body is provided in the rotating housing. An object of the present invention is to provide means capable of preventing a body from falling from a support member.

  (1) The composite printing apparatus according to the present invention has an opening on the upper surface, a first casing having a printing section for printing an image on a sheet in the opening, and a first connecting section on the first casing. A second housing that is connected to the first housing and is pivotable to a closed posture that covers the opening and an open posture that does not cover the opening, and a side surface of the second housing that is connected to the first connecting portion. And a support member that is connected to the second connection portion and can stand upright along the side surface, can be tilted outward from the side surface, and can be rotated to a tilted posture capable of supporting a supported body, and the tilted posture. The contact member that is in contact with the support member and narrows the rotation range of the support member, the contact member that can be moved to a separated position that does not contact the support member, and the contact member. In conjunction with the rotation from the closed position to the open position, Comprising an interlocking mechanism for moving the touch position. At least a part of the contact member is located outside the first casing at the contact position, and the contact member is entirely located inside the first casing at the separated position.

  According to this configuration, when the second housing rotates from the closed posture to the open posture, the support member coupled to the second housing also rotates integrally with the second housing. At this time, the contact member is moved from the separated position to the contact position by the interlocking mechanism. Thereby, a contact member contacts a support member and narrows the rotation range of a support member. As a result, even if the second housing rotates to the open posture, the rotation of the support member is restrained by the contact member. As described above, according to this configuration, the support member supported by the support member is supported because the rotation of the support member such that the rotation tip of the support member is positioned lower than expected is stopped by the contact member. It can prevent falling from a member.

  Further, according to this configuration, the contact member is located outside the first housing only when the second housing is rotated from the closed posture to the open posture side. That is, the contact member is located outside the first housing only when it is necessary to exhibit the function of narrowing the rotation range of the support member, and inside the first housing when the above is not necessary. I'm retracting. Thereby, the space which a composite printing apparatus occupies can be made small. Further, the appearance of the composite printing apparatus can be improved by bringing the contact member into a state of being retracted into the first housing. Moreover, the possibility that the contact member is damaged can be reduced by bringing the contact member into the first housing.

  (2) The interlocking mechanism can contact the second housing from below, and is continuous with the first guide surface and the first guide surface that are in contact with the contact member and held at the contact position. A guide member having a second guide surface that is in contact with the contact member and is held at the separated position, a first biasing member that biases the guide member toward the second housing, and the contact member. A second urging member that urges toward the guide member side. The guide member is movable to a first contact position where the first guide surface contacts the contact member and a second contact position where the second guide surface contacts the contact member. The guide member is located at the first contact position when the second casing is in the closed position, and is interlocked with the rotation of the second casing from the closed position to the open position. The urging force of the first urging member moves from the first contact position to the second contact position.

  According to this configuration, the function of the interlocking mechanism can be realized with a simple configuration in which only the urging member and the guide member are added.

  (3) The interlocking mechanism is provided in the second casing, and includes a first gear that rotates in the same direction as the rotation direction of the second casing, a rack gear that is provided in the contact member, A first gear and a second gear connecting the rack gear.

  According to this configuration, the function of the interlocking mechanism can be realized with a simple configuration in which only a few gears are added. Moreover, according to this structure, the 2nd housing | casing and the contact member are connected by the gear which meshed | engaged mutually. Therefore, the contact member can be reliably moved by the rotation of the second housing.

  (4) The contact member provided with the rack gear has an arc shape whose lower side is a curved outer side, and projects outward from below the support member.

  According to this configuration, the contact member provided below the support member protrudes outside while facing upward because the lower side is the curved outer side. As a result, the contact member comes into contact with the support member from below. As a result, the support member can be prevented from rotating in conjunction with the rotation of the second housing from the closed position to the open position.

  (5) The rotation axis of the second casing and the rotation axis of the support member are common.

  According to this configuration, the mechanism for rotating the second housing and the support member can be saved by sharing the rotation shaft.

  (6) The composite printing apparatus according to the present invention further includes a conveyance unit that conveys the sheet to the printing unit. The said support body is a sheet | seat conveyed by the said conveyance part.

  According to this configuration, as described in (1) above, it is possible to prevent the sheet supported by the support member from dropping. That is, this configuration is a preferable configuration for realizing the function (1).

  According to the present invention, when the support member that supports the supported body is provided in the second housing that rotates relative to the first housing, the supported body is supported by the rotation of the second housing. It can prevent falling from a member.

  When the scanner housing 34 is in the closed posture, the scanner housing 34 is supported by both the front end portion and the rear end portion of the printer housing 33. Thus, when the scanner housing 34 is in the closed posture, the scanner housing 34 covers the opening 44 (see FIG. 4B) formed in the upper surface 43 of the printer housing 33. On the other hand, when the scanner housing 34 is in the open posture, the scanner housing 34 is supported by the rear end portion of the printer housing 33 but is separated from the front end portion. Thereby, when the scanner housing 34 is in the open posture, the scanner housing 34 opens the opening 44 (see FIG. 4B) formed in the upper surface 43 of the printer housing 33. That is, the scanner housing 34 in the open posture does not cover the opening 44.

  The scanner housing 34 is maintained in a closed position when the multifunction machine 10 is used (when image data is acquired or when an image is recorded on the recording paper 15). On the other hand, the scanner housing 34 is rotated from the closed posture to the open posture in order to take out the recording paper 15 when the recording paper 15 is jammed inside the printer housing 33.

  The configuration for rotating the scanner housing 34 with respect to the printer housing 33 is not limited to the configuration described above. For example, an opening (not shown) opened in the left-right direction 9 is formed at the rear end portion of the scanner housing 34, and extends in the left-right direction 9 at the rear end portion of the printer housing 33 and is inserted into the opening. By forming the protrusions, the scanner housing 34 may rotate in the closed posture and the open posture with respect to the printer housing 33 around the protrusion. In this case, an opening opened in the left-right direction 9 at the rear end portion of the scanner housing 34 and a protrusion provided in the printer housing 33 and inserted through the opening are examples of the first connecting portion of the present invention. It is.

[Bypass tray 71]
The manual feed tray 71 is a substantially flat plate-shaped member. As shown in FIGS. 2 and 5A, the manual feed tray 71 is rotatably supported at the rear end portion of the scanner housing 34. Specifically, the manual feed tray 71 is connected to the printer housing 33 by the hinge 40 of the scanner housing 34, that is, the rear plate 57 that is the side surface of the scanner housing 34 on the rotation base end side. The body 34 is rotatably supported.

  Hereinafter, an example of a configuration for rotating the manual feed tray 71 with respect to the scanner housing 34 will be described. In the present embodiment, as shown in FIGS. 2 and 5A, a pair of protrusions 75 are formed on the manual feed tray 71. The pair of protrusions 75 are the lower end portions of the manual feed tray 71 and extend outward from both end portions in the left-right direction 9. On the other hand, a pair of openings 75 are formed in the scanner housing 34. The pair of openings 74 are formed in the side plate 42 that protrudes rearward from the rear plate 57 of the scanner housing 34. Each of the pair of protrusions 75 is inserted into each of the pair of openings 74. That is, the manual feed tray 71 is connected to the rear plate 57 of the scanner housing 34 via the pair of protrusions 75 and the pair of openings 74. That is, the pair of protrusions 75 and the pair of openings 74 are an example of the second connecting portion of the present invention.

  Here, the pair of protrusions 75 and the pair of openings 74 are located on one straight line extending in the left-right direction 9. As described above, the scanner housing 34 is rotated about the pair of protrusions 75 in the direction of the arrow 70 shown in FIGS. 2, 3B, and 5A, so that FIG. The standing posture can be changed to the standing posture shown in FIG. 5B and the tilting posture shown in FIG.

  When the manual feed tray 71 is in the upright posture, the manual feed tray 71 is closed to the rear plate 57 of the scanner housing 34 in the closed posture, that is, the rear plate 57 that extends in the vertical direction 7 and the horizontal direction 9 (of the scanner housing 34 in the closed posture). Stands along the side. On the other hand, when the manual feed tray 71 is in the tilted posture, the manual feed tray 71 is tilted outward from the rear plate 57 more than in the standing posture. Thereby, the manual feed tray 71 in the tilted posture can support the recording paper 15 on the upper surface thereof.

  Although not shown, the rear plate 57 of the scanner housing 34 is provided with a holding portion that holds the manual feed tray 71 in a state along the rear plate 57 by engaging with the manual feed tray 71 in the standing posture. ing. The manual feed tray 71 held in the state along the rear plate 57 by the holding unit is held when a certain force is applied in the direction of the arrow 89 shown in FIG. The engagement with the part is released, and it rotates in the direction of arrow 89. In the present embodiment, the manual feed tray 71 released from being held by the holding unit can be rotated in the direction of the arrow 89 by its own weight. Therefore, the rear plate 57 of the scanner housing 34 is provided with a stopper (not shown) for preventing the manual feed tray 71 from rotating in the direction of the arrow 89 without limit due to its own weight. The stopper abuts on the manual feed tray 71 to rotate the manual feed tray 71 in the direction of the arrow 89, and the angle of the manual feed tray 71 with respect to the rear plate 57 of the scanner housing 34 is θ1 (see FIG. 5B). Stop at the position.

  As shown in FIG. 2, the recording paper 15 is placed on the manual feed tray 71 in a state where the leading end of the recording paper 15 is in contact with the holding position by the conveying roller pair 63. Accordingly, when the transport roller 61 rotates, the recording paper 15 placed on the manual feed tray 71 is transported in the transport direction 16. That is, the recording paper 15 supported on the manual feed tray 71 is transported by the transport roller pair 63. 2, there is a second paper feed roller 67 that contacts the recording paper 15 placed on the manual feed tray 71 and feeds the recording paper 15 toward the conveyance roller pair 63 as indicated by a broken line. It may be provided. In this case, the recording paper 15 is placed on the manual feed tray 71 in a state where the leading end thereof does not contact the holding position by the conveying roller pair 63.

  Note that the configuration for rotating the manual feed tray 71 with respect to the scanner housing 34 is not limited to the configuration described above. For example, contrary to the above, a pair of openings 74 may be formed in the manual feed tray 71, and a pair of protrusions 75 may be formed on the side plate 42 protruding rearward from the rear plate 57 of the scanner housing 34. For example, the manual feed tray 71 and the scanner housing 34 may be connected by a hinge (not shown).

  In the present embodiment, as shown in FIG. 5, the hinge 40 and the protrusion 75 are provided at different positions in the front-rear direction 8 and the vertical direction 7. That is, the rotation center of the scanner housing 34 and the rotation center of the manual feed tray 71 are different. However, the rotation center of the scanner housing 34 and the rotation center of the manual feed tray 71 may be the same axis. In other words, the rotation axis of the scanner housing 34 and the rotation axis of the manual feed tray 71 may be common. For example, by providing the hinge 40 inside the pair of protrusions 75 along the left-right direction 9, the rotation axis of the scanner housing 34 and the rotation axis of the manual feed tray 71 can be made common.

[Contact member 72]
As shown in FIG. 5A, a contact member 72 is disposed inside the printer housing 33. In the present embodiment, the contact member 72 is disposed at the rear end of the scanner housing 34. Further, the contact member 72 is a substantially rod-shaped member extending in the front-rear direction 8. The contact member 72 is connected to the printer casing 33 via a coil spring 81 extending in the front-rear direction 8 described later. Thereby, the contact member 72 is movable along the front-rear direction 8. Specifically, the contact member 72 is movable to the separated position shown in FIG. 5 and the contact position shown in FIG. Here, all of the contact members 72 in the separated position are located inside the printer housing 33. On the other hand, the contact member 72 at the contact position is located behind the rear wall 82, part of the rear side of which forms the rear surface of the printer housing 33. That is, a part of the contact member 72 at the contact position protrudes outside the printer housing 33. Note that all of the contact members 72 at the contact positions may protrude outside the printer housing 33. That is, at least a part of the contact member 72 at the contact position protrudes outside the printer housing 33.

  The rear end portion of the contact member 72 at the contact position, that is, the protruding front end portion can contact the manual feed tray 71. On the other hand, the contact member 72 in the separated position is separated from the manual feed tray 71. That is, the contact member 72 at the separated position does not contact the manual feed tray 71.

[Interlocking mechanism 73]

The rear surface of the guide member 83 is continuous with the first guide surface 87 extending in the tilt direction and the left-right direction 9 so as to be the lower side as it is lower, and the lower end of the first guide surface 87. And the 2nd guide surface 88 extended in the left-right direction 9 is comprised.

  The coil spring 81 extends in the front-rear direction 8. The front end of the coil spring 81 is in contact with the contact member 72, and the rear end of the coil spring 81 is in contact with the frame 85 of the printer unit 12 covered with the printer housing 33. Note that the rear end of the coil spring 81 may be in contact with the printer housing 33. The coil spring 81 is arranged so that a state shorter than the natural length is maintained. As a result, the contact member 72 is pressed against the guide member 83 by the forward biasing force of the coil spring 81. That is, the coil spring 81 biases the contact member 72 toward the guide member 83.

  The coil spring 84 extends in the vertical direction 7. The upper end of the coil spring 84 is in contact with the guide member 83, and the lower end of the coil spring 84 is in contact with the frame 86 of the printer unit 12 covered with the printer housing 33. Note that the lower end of the coil spring 84 may be in contact with the printer housing 33. The coil spring 81 is arranged so that a state shorter than the natural length is maintained. Accordingly, the guide member 83 is pressed against the scanner housing 34 by the upward biasing force of the coil spring 84. That is, the coil spring 84 biases the guide member 83 toward the scanner housing 34 side.

[Operations of the respective units 71, 72, 73 when the scanner housing 34 is rotated]
Hereinafter, the operations of the manual feed tray 71, the contact member 72, and the interlocking mechanism 73 when the scanner housing 34 is rotated from the closed posture to the open posture in a state where the manual feed tray 71 is in the tilted posture will be described with reference to FIGS. Will be described in detail with reference to FIG.

  The state shown in FIG. 5A is a state where the scanner housing 34 is in the closed posture and the manual feed tray 71 is in the standing posture. In the state shown in FIG. 5A, when the manual feed tray 71 is rotated in the direction of the arrow 89 which is one direction of the arrow 70, the manual feed tray 71 is tilted as shown in FIG. The posture is changed to the posture. That is, the state shown in FIG. 5B is a state in which the scanner housing 34 is in a closed posture and the manual feed tray 71 is in a tilted posture.

  When the scanner housing 34 is in the closed position, the guide member 83 is pressed against the lower surface of the scanner housing 34 by being biased upward by the coil spring 84. At this time, the position of the first guide surface 87 of the guide member 83 in the vertical direction 7 is the same position as the position of the contact member 72 in the vertical direction 7. The position of the guide member 83 at this time, that is, the position of the guide member 83 shown in FIG. 5 is the first contact position of the present invention.

  When the guide member 83 is in the first contact position, the contact member 72 is pressed against the first guide surface 87 of the guide member 83 by being biased forward by the coil spring 81. That is, the guide member 83 is located at the first contact position where the first guide surface 87 contacts the contact member 72 in a state where the scanner housing 34 is in the closed posture. At this time, the entire contact member 72 is located inside the printer housing 33. The position of the contact member 72 at this time, that is, the position of the contact member 72 shown in FIG. 5 is the separation position described above. That is, the first guide surface 87 is in contact with the contact member 72 and is held at the separated position.

  In the state shown in FIG. 5B, when the scanner housing 34 is rotated in the direction of the arrow 90 which is one direction of the arrow 69, the scanner housing 34 should change its posture from the closed posture to the open posture. Start turning. Thereby, as shown in FIG. 6A, the front portion of the scanner housing 34 is separated from the printer housing 33. As a result, the scanner housing 34 is tilted so that the front side is positioned above the rear side.

  When the scanner housing 34 is rotated, the manual feed tray 71 is also rotated integrally with the scanner housing 34. That is, the scanner housing 34 and the manual feed tray 71 rotate while keeping the angle θ1 of the manual feed tray 71 with respect to the rear plate 57 of the scanner housing 34 constant. However, the manual feed tray 71 rotates integrally with the scanner housing 34 until the manual feed tray 71 contacts the contact member 72 as described later. As described above, the manual feed tray 71 is rotated integrally with the scanner casing 34, that is, in conjunction with the rotation of the scanner casing 34, as shown in FIG. On the other hand, while maintaining the tilted posture, it is tilted further outward than the state shown in FIG.

  Further, when the scanner housing 34 is rotated and separated from the printer housing 33 on the front side of the hinge 40, the guide member urged upward by the coil spring 84 as shown in FIG. 83 moves upward following the lower surface of the scanner housing 34. As a result, the first guide surface 87 of the guide member 83 is positioned above the contact member 72. Instead, the position of the second guide surface 88 of the guide member 83 in the vertical direction 7 and the position of the contact member 72 in the vertical direction 7 are the same position. The position of the guide member 83 at this time, that is, the position of the guide member 83 shown in FIG. 6A is the second contact position of the present invention.

  When the guide member 83 is in the second contact position, the contact member 72 is pressed against the second guide surface 88 of the guide member 83 by being biased forward by the coil spring 81. Here, the second guide surface 88 is located behind the first guide surface 87. Therefore, the contact member 72 that is separated from the first guide surface 87 and is in contact with the second guide surface 88 moves rearward from the separation position. As a result, the rear end portion of the contact member 72 protrudes outside the printer housing 33. The position of the contact member 72 at this time, that is, the position of the contact member 72 shown in FIG. 6A is the contact position described above. That is, the second guide surface 88 is in contact with the contact member 72 and is held at the contact position.

  The contact member 72 at the contact position contacts the manual feed tray 71 that rotates together with the scanner housing 34 that rotates in the direction of the arrow 90. In the present embodiment, as shown in FIG. 6A, the contact member 72 is in contact with, or in contact with, the opposite side of the scanner housing 34 with respect to the rotation shaft (protrusion 75) of the manual feed tray 71.

  Here, the posture of the scanner housing 34 in the state shown in FIG. 6A is closer to the open posture than the closed posture shown in FIG. 5 and is closer to the closed posture than the open posture shown in FIG. It is. That is, the posture of the scanner housing 34 in the state of FIG. 6A is between the closed posture and the open posture. As described above, the contact member 72 is in a state in which the scanner housing 34 is between the closed posture and the open posture and the manual feed tray 71 is tilted with respect to the scanner housing 34, that is, as shown in FIG. In this state, the manual feed tray 71 is contacted. In other words, the contact member 72 contacts the manual feed tray 71 in the process in which the scanner housing 34 rotates from the closed posture to the open posture with the manual feed tray 71 in the tilted posture.

  As described above, in the state of FIG. 5B, the contact member 72 is in the separated position, and the scanner housing 34 is in the closed posture. On the other hand, in the state of FIG. 6A, the contact member 72 is in the contact position, and the scanner housing 34 is in a posture between the closed posture and the open posture. That is, the interlocking mechanism 73 moves the contact member 72 from the separated position to the contact position in conjunction with a change in the posture of the scanner housing 34 from the closed position to the open position.

  Further, as described above, in the state of FIG. 5B, the guide member 83 is in the first contact position, and the scanner housing 34 is in the closed posture. On the other hand, in the state of FIG. 6A, the guide member 83 is in the second contact position, and the scanner housing 34 is in the posture between the closed posture and the open posture. That is, the guide member 83 moves from the first contact position to the second contact position by the urging force of the coil spring 84 in conjunction with the change in the posture of the scanner housing 34 from the closed position to the open position.

  When the scanner casing 34 is further rotated in the direction of the arrow 90 in the state shown in FIG. 6A, the scanner casing 34 is shown in FIG. 6B from the posture shown in FIG. The posture changes to the open posture. At this time, since the manual feed tray 71 is in contact with the contact member 72, it does not rotate integrally with the scanner housing 34. In other words, the rotation of the manual feed tray 71 interlocked with the rotation of the scanner housing 34 from the posture shown in FIG. That is, even when the scanner housing 34 is rotated from the posture shown in FIG. 6A to the open posture, the manual feed tray 71 remains at the position in FIG. Therefore, the angle θ2 (see FIG. 6B) of the manual feed tray 71 with respect to the rear plate 57 of the scanner housing 34 in a state where the scanner housing 34 is in the open posture is the state in which the scanner housing 34 is in the closed posture and the fifth posture. The angle θ1 of the manual feed tray 71 with respect to the rear plate 57 of the scanner housing 34 is smaller than the angle θ1 (see FIGS. 5B and 6A). That is, when the scanner housing 34 is rotated from the posture shown in FIG. 6A to the open posture, the manual feed tray 71 is rotated in a direction relatively approaching the rear plate 57 of the scanner housing 34.

  As described above, the contact member 72 prevents the manual feed tray 71 in the tilted posture from being tilted outward from the position shown in FIG. That is, the contact member 72 comes into contact with the manual feed tray 71 in the tilted posture, and narrows the rotation range of the manual feed tray 71.

  In the present embodiment, when the scanner housing 34 is in the open posture shown in FIG. 6B, the guide member 83 is separated from the lower surface of the scanner housing 34. In this embodiment, the coil spring 84 extends to the natural length in the process of changing the posture of the scanner housing 34 from the posture shown in FIG. 6 (A) to the open posture shown in FIG. 6 (B). This is because the upward movement of the guide member 83 is stopped. Of course, the guide member 83 may be in contact with the lower surface of the scanner housing 34 when the scanner housing 34 is in the open posture shown in FIG.

  When the scanner housing 34 rotates from the open posture to the closed posture, an operation opposite to the operation when the scanner housing 34 rotates from the closed posture to the open posture is executed. This will be described in detail below. In the state shown in FIG. 6B, when the scanner housing 34 is rotated in the direction of the arrow 92 which is the other direction of the arrow 69, the manual feed tray 71 is not in contact with the above-described stopper. Regardless of the rotation of the body 34, it remains at the position shown in FIG. Thereafter, when the scanner case 34 is rotated to the posture shown in FIG. 6A, when the manual feed tray 71 comes into contact with the stopper, the manual feed tray 71 starts to rotate integrally with the scanner case 34. .

  In the state shown in FIG. 6A, when the scanner housing 34 is further rotated in the direction of the arrow 92, that is, the scanner housing 34 is rotated from the posture shown in FIG. 6A toward the closed posture. When moved, the guide member 83 moves from the second contact position to the first contact position against the urging force of the coil spring 84 by being pushed by the lower surface of the scanner housing 34. Thus, the second guide surface 88 is separated from the contact member 72 and the first guide surface 87 is in contact with the contact member 72. As a result, the contact member 72 moves from the contact position to the separated position by the biasing force of the coil spring 81. Then, the scanner casing 34 rotated in the direction of the arrow 92 is in a closed position when the front portion thereof is in contact with the printer casing 33 and is supported by the printer casing 33 (FIG. 5). (See (B)). In the state shown in FIG. 5B, the manual feed tray 71 is tilted. In the state shown in FIG. 5B, the manual feed tray 71 stands up from the tilted posture by being rotated in the direction of the arrow 93 (see FIG. 5A), which is the other direction of the arrow 70. The posture changes to the posture (see FIG. 5A).

[Effect of the embodiment]
According to this embodiment, when the scanner housing 34 rotates from the closed posture to the open posture, the manual feed tray 71 connected to the scanner housing 34 also rotates integrally with the scanner housing 34. At this time, the contact member 72 is moved from the separated position to the contact position by the interlocking mechanism 73. Thereby, the contact member 72 contacts the manual feed tray 71 to narrow the rotation range of the manual feed tray 71. As a result, even if the scanner housing 34 is rotated to the open posture, the rotation of the manual feed tray 71 is stopped by the contact member 72. As described above, according to the present embodiment, since the rotation of the manual feed tray 71 such that the rotation tip of the manual feed tray 71 is located below the expected position is stopped by the contact member 72, the manual feed tray 71 is supported by the manual feed tray 71. It is possible to prevent the recording paper 15 from falling from the manual feed tray 71. That is, according to the present embodiment, when the manual feed tray 71 that supports the recording paper 15 is provided in the scanner housing 34 that rotates with respect to the printer housing 33, recording is performed by the rotation of the scanner housing 34. It is possible to prevent the paper 15 from falling from the manual feed tray 71.

  Further, according to the present embodiment, the contact member 72 is located outside the printer housing 33 only when the scanner housing 34 is rotated from the closed posture to the open posture side. That is, the contact member 72 is located outside the printer housing 33 only when it is necessary to exhibit the function of narrowing the rotation range of the manual feed tray 71. Recessed inside. As a result, the space occupied by the multifunction machine 10 can be reduced. In addition, when the contact member 72 is retracted into the printer housing 33, the appearance of the multifunction machine 10 can be improved. Further, by bringing the contact member 72 into the printer housing 33, the possibility of damage to the contact member 72 can be reduced.

  Further, according to the present embodiment, the function of the interlocking mechanism 73 can be realized with a simple configuration in which the coil springs 81 and 84 and the guide member 83 are simply added.

  Further, when the rotation axis of the scanner housing 34 and the manual feed tray 71 are made common, a mechanism for rotating the scanner housing 34 and the manual feed tray 71 can be saved.

  In addition, according to the present embodiment, as described above, the recording paper 15 supported by the manual feed tray 71 can be prevented from falling. That is, the present embodiment in which the supported body according to the present invention is the recording paper 15 and the support member according to the present invention is the manual feed tray 71 is a preferable configuration for realizing the functions of the present invention.

[Modification 1]
In the above-described embodiment, the rotation shafts of the scanner housing 34 and the manual feed tray 71 are fixed at one position. However, the rotation shafts may move. For example, as shown in FIG. 7, the rotation shaft 94 of the manual feed tray 71 rotates the manual feed tray 71 from the standing posture (see FIG. 7A) to the tilting posture (see FIG. 7B). Therefore, it may be configured to slide backward.

[Modification 2]
In the above-described embodiment, the interlocking mechanism 73 has a configuration including the guide member 83, the coil spring 81, and the coil spring 84. However, the interlocking mechanism 73 is not limited to the configuration in the above-described embodiment. For example, the interlocking mechanism 73 may be configured to include a first gear 95, a second gear 96, and a rack gear 97 as shown in FIG.

  The first gear 95 is provided in the scanner housing 34. In FIG. 7, the first gear 95 protrudes in an arc shape from the lower surface of the scanner housing 34. Further, the teeth of the first gear 95 are formed inside the curved arc. The first gear 95 rotates integrally with the scanner housing 34. In other words, the first gear 95 rotates in the same direction as the scanner housing 34 around the rotation axis of the scanner housing 34.

  The rack gear 97 is formed on the contact member 72. That is, in FIG. 7, the contact member 72 is disposed in the printer housing 33 so as to be movable in the front-rear direction 8 as in the above-described embodiment, and the rack gear 97 is formed on the lower surface thereof. In the second modification, the rack gear 97 is formed along the front-rear direction 8 which is a direction connecting the separation position and the contact position.

  The second gear 96 is provided in the printer housing 33. The second gear 96 has a cylindrical shape and rotates around a shaft 98 extending in the left-right direction 9. The second gear 96 meshes with the first gear 95 and the rack gear 97. That is, the second gear 96 connects the first gear 95 and the rack gear 97.

  Since the interlocking mechanism 73 is configured as shown in FIG. 7, the interlocking mechanism 73 operates as follows. That is, when the scanner housing 34 is rotated from the closed position to the open position, that is, in the direction of the arrow 90 shown in FIGS. 7A and 7C, the first gear 95 is also rotated in the direction of the arrow 90. To do. As the first gear 95 rotates, the second gear 96 meshing with the first gear 95 rotates in the direction of the arrow 99 shown in FIG. Due to the rotation of the second gear 96 in the direction of the arrow 99, the contact member 72 having the rack gear 97 engaged with the second gear 96 slides in the direction of the arrow 100 shown in FIG. Accordingly, as shown in FIG. 7C, the rear end portion of the contact member 72 protrudes from the printer housing 33 and comes into contact with the manual feed tray 71.

  In the example of FIG. 7, the first gear 95 protrudes in an arc shape from the lower surface of the scanner housing 34, but the first gear 95 is coaxial with the scanner housing 34 as shown in FIG. A rotating cylindrical gear may be used. In FIG. 8, the second gear 96 is disposed on the front side of the first gear 95, and the rack gear 97 is formed on the upper surface of the contact member 72. Since the interlocking mechanism 73 is configured as shown in FIG. 8, the interlocking mechanism 73 operates as follows. That is, when the scanner housing 34 is rotated from the closed posture to the open posture, that is, in the direction of the arrow 90 (see FIG. 8C), the first gear 95 is also integrated with the scanner housing 34 in the direction of the arrow 90 (see FIG. 8). 8 (see (A)). As the first gear 95 rotates, the second gear 96 meshing with the first gear 95 rotates in the direction opposite to the arrow 90. Due to the rotation of the second gear 96, the contact member 72 having the rack gear 97 engaged with the second gear 96 slides in the direction of the arrow 100. As a result, as shown in FIG. 8C, the rear end portion of the contact member 72 protrudes from the printer housing 33 and contacts the manual feed tray 71.

  According to the modification 2, the function of the interlocking mechanism 73 can be realized with a simple configuration in which only a few gears 95 to 97 are added. Further, according to the second modification, the scanner housing 34 and the contact member 72 are connected by the gears engaged with each other. Therefore, the contact member 72 can be reliably moved by the rotation of the scanner housing 34.

[Modification 3]
In the modified example 2, the contact member 72 provided with the rack gear 97 is formed along the front-rear direction 8, but the contact member 72 is not limited to the shape along the front-rear direction 8. For example, as shown in FIG. 9, the contact member 72 provided with the rack gear 97 has an arc shape whose lower side is a curved outer side, and may protrude outward from below the manual feed tray 71.

  Since the contact member 72 is configured as shown in FIG. 9, the interlocking mechanism 73 operates as follows. That is, when the scanner housing 34 is rotated from the closed position to the open position, that is, in the direction of the arrow 90 shown in FIGS. 9A and 9C, the first gear 95 is also rotated in the direction of the arrow 90. To do. As the first gear 95 rotates, the second gear 96 meshing with the first gear 95 rotates in the direction of the arrow 99 shown in FIG. Due to the rotation of the second gear 96 in the direction of the arrow 99, the contact member 72 having the rack gear 97 meshed with the second gear 96 is rotated in the direction of the arrow 101 shown in FIG. As a result, as shown in FIG. 9C, the contact member 72 protrudes from the printer housing 33 so that its rear end portion is directed upward, and comes into contact with the manual feed tray 71 from below.

  According to the third modification, the contact member 72 provided below the manual feed tray 71 projects outward while facing upward because the lower side is the curved outer side. Thereby, the contact member 72 contacts the manual feed tray 71 from below. As a result, the manual feed tray 71 can be prevented from rotating in conjunction with the rotation of the scanner housing 34 from the closed position to the open position.

[Modification 4]
In the above-described embodiment, the support member of the present invention is the manual feed tray 71, and the supported body of the present invention is the recording paper 15 supported by the manual feed tray 71. However, the support member of the present invention may not be the manual feed tray 71 as long as the support member is supported by the scanner housing 34 and rotated to the standing posture and the tilting posture.

  For example, the support member of the present invention may be a device tray on which an electronic device such as a tablet terminal having a function of communicating with the multifunction device 10 by NFC (Near Field Communication) or the like is supported. Similar to the manual feed tray 71 of the above-described embodiment, the device tray is supported by the scanner housing 34 and rotated to a standing posture and a tilting posture. For example, when the manual feed tray 71 shown in FIG. 6A is a device tray, the electronic device 50 is supported on the upper surface of the device tray as shown by a broken line in FIG. The electronic device is not limited to exchanging information by communicating with the multifunction machine 10. For example, the device tray may electrically connect the electronic device to be supported to the multifunction device 10. Specifically, the device tray may be configured such that, when an electronic device is placed on the upper surface, the electronic device and the control unit that controls the multifunction machine 10 are electrically connected. Good. In the above case, the supported body of the present invention is an electronic device.
