  2. Description of the Related Art Conventionally, some printers, scanners, copiers, telephones, facsimile machines, and the like are provided with an electronic device having operation buttons, a touch panel, and the like.

  The operation panel and the like are assumed to be operated from the upper surface side of the apparatus and operated from the front side of the apparatus. Therefore, if the operation panel or the like is directed to the upper surface side of the apparatus, the operability from the front side of the apparatus is deteriorated. On the other hand, if the operation panel or the like is directed to the front side of the apparatus, the operability from the upper surface side of the apparatus is degraded. In order to solve this problem, there has been proposed a device in which an operation panel or the like is provided in the apparatus main body so as to be rotatable, and the attitude of the operation panel or the like can be changed so as to face an arbitrary direction on the upper surface side of the apparatus or the front side of the apparatus. . Such an electronic device is provided with a mechanism that allows an operation panel or the like to be held in an arbitrary posture, that is, a so-called tilt mechanism.

A panel device is disclosed. In order to rotate the panel body 23 in the panel device, it is necessary to release the lock. When releasing the lock, the user puts a finger between the upper surface of the panel body 23 and the operation unit 35 and applies a force in a direction to lift the operation unit 35 upward.

JP 2011-22303 A

  In the panel device disclosed in Patent Document 1, when the user tries to return the panel main body 23 to the housed state without releasing the lock, the following problem occurs. In the above case, a large force acts on the panel body 23. Then, the panel main body 23 bends around the vicinity of the engagement fixing portion 31 that is a locked portion. As a result, components inside the panel body 23, such as a liquid crystal display, a printed circuit board, or an electronic component mounted on the printed circuit board, may be damaged.

  The present invention has been made in view of the above problems, and an object thereof is to provide an electronic device that can reduce the possibility of damage to internal components even when a large force is applied, and the electronic device. Another object is to provide an image recording apparatus.

  (1) An electronic device of the present invention supports a panel provided with a plurality of processing units that perform display processing for displaying predetermined information or operation processing for receiving a predetermined operation, and the panel rotatably. A main body and a holding mechanism for holding the panel at a desired rotation angle. The panel rotates about a direction along the direction in which the plurality of processing units are arranged as a rotation axis to a first position and a second position where the rotation tip is farther from the main body than the first position. It moves. The holding mechanism includes an engaging portion provided in the panel and an engaged portion provided in the main body and engaged with the engaging portion, and a direction in which the plurality of processing units are arranged. In the area of any one of the above processing units.

  When a large force for rotating the panel from the second position to the first position is applied to the end portion in the direction along the rotation axis of the panel, the panel is bent. However, when the holding mechanism is arranged at a position as in this configuration, the panel bends around the place where the holding mechanism is provided. Specifically, the panel 70 bends around the engagement portion between the engaging portion and the engaged portion. Thereby, the force in the bending direction that bends the processing unit itself caused by the bending of the panel is alleviated.

  (2) The engaged portion includes a recess that is arranged in parallel along the rotation direction of the panel and is recessed toward the rotation axis of the panel. The engaging portion is pivotally attached to the panel and has a lever portion formed with a protruding member capable of engaging with and disengaging from the concave portion at a rotating tip, and a first portion where the protruding member engages with the concave portion. And an urging member that elastically urges the lever portion in the direction. When the panel at the second position is pushed toward the first position with a force equal to or greater than a preset pressing force, the projecting member has the biasing force in the first direction by the biasing member and the A force greater than the sum of the frictional force of the projecting member and the concave portion and a force opposite to the first direction is applied.

  According to this configuration, when the panel at the second position is pushed to the first position side with a force equal to or greater than a preset pressing force, the projecting member engaged with the recess is first acted on the projecting member. It is separated from the recess by the force opposite to the direction. Thereby, it is possible to prevent a large force from acting on the panel. That is, the processing unit can be prevented from being damaged by setting the pressing force to be smaller than a force that can damage the processing unit.

  (3) The area of the engaging portion between the engaging portion and the engaged portion in the third position in the direction in which the processing units are arranged is larger than the third position in the direction in which the processing units are arranged. The distance from the end of the processing unit is smaller than the area of the engaging portion between the engaging portion and the engaged portion at the fourth position.

  According to this configuration, when a force for rotating the panel to the first position is applied to the panel, the engagement between the engaging portion and the engaged portion at the third position where the area of the engaging portion is small is achieved. The engagement portion is released before the engagement between the engagement portion and the engaged portion in the fourth position where the area of the engagement portion is large. Here, in many cases, the deflection of the panel increases as the distance from the end of the processing unit increases, that is, as the center of the processing unit increases. That is, in this configuration, the engagement between the engaging portion and the engaged portion is first released at the third position where the bending is large. As a result, it is possible to reduce the possibility of the processing unit being damaged due to the bending of the panel.

  (4) The lever portion is different from the first lever portion extending from the rotation center of the engaging portion to the engaged portion side and the engaged portion side from the rotation center of the engaging portion. And a second lever portion extending to the side. The protruding member is formed at the rotating tip of the first lever portion. A gripping portion that is gripped to rotate the engagement portion is formed at the rotation tip of the second lever portion.

  According to this configuration, the projecting member can be detached from the recess by gripping the grip portion and rotating the engagement portion. That is, the engaging part can be detached from the engaged part. As a result, the panel can be rotated at different rotation angles. As described above, according to this configuration, the panel can be rotated without applying a large force to the panel by gripping the grip portion and rotating the engaging portion.

  (5) A plurality of the engaging portions and the engaged portions are provided along the direction in which the processing units are arranged.

  According to this configuration, the panel can be held more stably than when only one engaging portion and one engaged portion are provided.

  (6) At least one of the plurality of processing units is a touch panel. The holding mechanism is arranged at a position different from the touch panel in the direction in which the plurality of processing units are arranged.

  In general, the touch panel is more easily damaged than other processing units. Therefore, in this configuration, the holding mechanism and the touch panel are arranged at different positions. Thereby, it can reduce that the force of the bending direction which bends the touch panel itself with respect to a touch panel acts. As a result, the possibility that the touch panel is damaged can be reduced.

  (7) It further includes a control board on which a control unit for controlling the operation of the apparatus is mounted. The control board is disposed at a position different from the engaged portion in the direction in which the plurality of processing units are arranged.

  According to this configuration, it is possible to prevent contact between the holding mechanism and the control board when the panel is rotated. Moreover, according to this structure, since the space which arrange | positions a member can be used without waste in the direction in which the several processing unit was put in order, an apparatus can be reduced in size.

  (8) An operating device according to the present invention includes an electronic device according to any one of (1) to (7), a recording unit that records an image on a sheet, and an image recorded on the recording unit below the panel. It can also be grasped as an image recording apparatus provided with a placement unit for placing the sheet thus obtained.

  According to this configuration, there is a case where the interval between the panel and the placement portion can be increased by rotating the panel. In this case, it is possible to easily take out the sheet placed on the placement unit.

(9) The image recording apparatus of the present invention supports a panel provided with a plurality of processing units arranged to perform a display process for displaying predetermined information or an operation process for receiving a predetermined operation, and the panel rotatably. A main body, a holding mechanism for holding the panel at a desired rotation angle, a recording unit for recording an image on a sheet according to processing by the processing unit, and an image on the recording unit below the panel. And a placement unit on which the recorded sheet is placed. The holding mechanism is provided with a rotating member that is rotatable with respect to the panel, an engaging member that is provided on the rotating member, and an engaging member that is provided on the main body and engages with the engaging member. An engaged member. The panel includes a holding portion that rotatably holds the support rotation member, and the first position and a lower side of the panel are arranged with a rotation axis in a direction along a direction in which the plurality of processing units are arranged. It rotates to a second position farther from the main body than the first position,
The engaging member, the engaged member, and the holding portion are arranged in a region of any one of the processing units in a direction in which the plurality of processing units are arranged.

  Even if the engaging member and the engaged member are arranged in the region of any one processing unit in the direction in which the plurality of processing units are arranged, if the holding portion is arranged outside the region, The panel is bent by the action of a large force that attempts to rotate the panel from the second position to the first position. However, according to this configuration, the engaging member, the engaged member, and the holding portion are arranged in the region of any one processing unit in the direction in which the plurality of processing units are arranged. Thereby, the force applied to the panel can be reduced. As a result, the possibility that the panel bends can be reduced.

  Further, according to this configuration, it is possible to make it easier to take out the sheet placed on the placement unit, similarly to (8).

  According to the present invention, the force in the bending direction for bending the processing unit itself caused by the bending of the panel is alleviated. Therefore, according to this invention, even if big force acts on the edge part of a panel, possibility that the processing unit provided in the panel will be damaged can be made low.

The rotation angle of the panel 70 with respect to the first position in the second position is determined depending on which of the three recesses 97 </ b> A to 97 </ b> C is engaged with the protruding member 91. Specifically, in a state where the protruding member 91 is engaged with the recess 97C (see FIG. 6), the rotation angle is larger than in a state where the protruding member 91 is engaged with the recessed portion 97B (see FIG. 5). When the protruding member 91 is positioned above the recess 97A (see FIG. 4), the panel 70 is disposed along the front surface 41 of the printer housing 14, that is, in the first position.

  The area of the engaging portion between the concave portion 97 and the protruding member 91 is larger in the left-right direction 9 as it is the central portion of the operation key portion 72. This will be described in detail below. As described above, the protruding length of the protruding member 91 at the left end 78 of the rotating tip of the first lever portion 86 is greater than the protruding length of the protruding member 91 at the right end 79 of the rotating tip of the first lever 86. (See FIG. 8B). Thereby, when the recess 97 and the protrusion 91 are engaged, the depth at which the protrusion 91 of the left end 78 enters the recess 97 (see FIG. 9B) is such that the protrusion 91 of the right end 79 has the recess 97. Deeper than the depth of penetration (see FIG. 9A). As a result, the area of the engaging portion between the protruding member 91 at the left end portion 78 and the recessed portion 97 is larger than the area of the engaging portion between the protruding member 91 at the right end portion 79 and the recessed portion 97.

  Here, as shown in FIG. 2B, the left end portion 78 of the turning tip portion of the first lever portion 86 is more than the right end portion 79 of the turning tip portion of the first lever portion 86, and the operation key portion. The distance from the left end 77 of 72 is small. That is, the engagement portion between the protruding member 91 that is a part of the engaging portion 82 of the right end portion 79 (an example of the third position of the present invention) in the left-right direction 9 and the concave portion 97 that is a part of the engaged portion 93. Is smaller than the area of the engaging portion between the projecting member 91 and the recess 97 at the left end 78 (an example of the fourth position of the present invention) that is smaller in distance from the left end 77 than the right end 79 in the left-right direction 9. .

[Separation of protruding member 91 from recess 97]
As shown in FIG. 9A, when the panel 70 at the second position is pushed to the first position side with a force equal to or higher than the pressing force F1 set in advance, the protruding member 91 is provided on the protruding member 91. A force F <b> 2 opposite to the direction engaging with the recess 97, that is, the direction of the arrow 96 (see FIGS. 6 and 9A) is applied. Here, as the force F2, a force larger than the sum of the urging force F4 in the direction of the arrow 96 by the torsion spring 51 and the frictional force of the projecting member 91 and the recess 97 is applied.

  This will be described in detail below. The pressing force F <b> 1 is set to be smaller than a force that can damage the operation key unit 72 and the touch panel 73. When the panel 70 in the second position is pushed to the first position side, the pressing force F1 is generated from the rotation shaft 85 of the lever portion 84 of the engaging portion 82 including the protruding member 91 and the engaged member 91 and the engaged portion. The force of the direction to the contact 98 with the recess 97 of 83 is obtained.

  When the pressing force F1 is decomposed at the common tangent line 101 and the common normal line 102 between the projecting member 91 and the recess 97, the force F2 in the direction along the common tangent 101 is separated from the recess 97 by the projecting member 91. The power to try.

  Further, the frictional force generated when the projecting member 91 is about to be separated from the recess 97 can be obtained from the formula F = μN. Here, μ is a friction coefficient. N is a force F3 in the direction along the common normal line 102 when the pressing force F1 is decomposed at the common tangent line 101 and the common normal line 102 between the protruding member 91 and the recess 97. That is, the frictional force can be obtained by μ · F3.

  In this embodiment, the force F2 is larger than the sum of the force F4 and the frictional force μ · F3. As described above, when the panel 70 in the second position is pushed to the first position side with a force equal to or greater than the pressing force F1, the restraining of the rotation of the panel 70 by the engaging portion 82 and the engaged portion 83 is released, The panel 70 rotates to the first position side.

[Effect of the embodiment]
When a large force for rotating the panel 70 from the second position to the first position is applied to the end portion of the panel 70 in the left-right direction 9, the panel 70 is bent. However, when the holding mechanism 81 is arranged at a position as in the present embodiment, the panel 70 bends around the place where the holding mechanism 81 is provided. Specifically, the panel 70 bends around the position where the protruding portion 91 of the engaging portion 82 and the recessed portion 97 of the engaged portion 83 are engaged and the position of the holding portion 88. Thereby, the force in the bending direction that bends the operation key portion 72 itself and the touch panel 73 itself caused by the bending of the panel 70 is alleviated. Therefore, according to the present embodiment, even if a large force acts on the end portion of the panel 70, the possibility that the operation key portion 72 and the touch panel 73 provided on the panel 70 are damaged can be reduced.

  Further, according to the present embodiment, when the panel 70 in the second position is pushed to the first position side with a force equal to or greater than the preset pressing force F1, the projecting member 91 engaged with the recess 97 is projected. The member is separated from the recess 97 by a force F <b> 2 opposite to the direction of the arrow 96 applied to the member 91. Thereby, it is possible to prevent a large force from acting on the panel 70. That is, by setting the pressing force F <b> 1 smaller than the force that damages the operation key unit 72 and the touch panel 73, the operation key unit 72 and the touch panel 73 can be prevented from being damaged.

  In addition, according to the present embodiment, when a force for turning the panel 70 to the first position is applied to the panel 70, the right end of the turning tip portion of the first lever portion 86 having a small area of the engaging portion. The engagement between the engaging portion 82 and the engaged portion 83 in the portion 79 is such that the engaging portion 82 and the engaged portion at the right end 79 of the rotating tip portion of the first lever portion 86 having a large area of the engaging portion. It is released before the engagement with 83. Here, in many cases, the deflection of the panel 70 increases as the distance from the end of the operation key unit 72 (or touch panel 73) increases, that is, as the center of the operation key unit 72 (or touch panel 73) increases. In other words, in the present embodiment, the engagement between the engaging portion 82 and the engaged portion 83 is first released at the right end portion 79 where the bending is large. As a result, it is possible to reduce the possibility that the operation key unit 72 and the touch panel 73 are damaged by the bending of the panel 70.

  Further, according to the present embodiment, the projecting member 91 can be detached from the recess 97 by gripping the grip portion 92 and rotating the engaging portion 82. That is, the engaging portion 82 can be detached from the engaged portion 83. As a result, the panel 70 can be rotated at different rotation angles. As described above, according to the present embodiment, the panel 70 can be rotated without applying a large force to the panel 70 by gripping the grip portion 92 and rotating the engaging portion 82.

  In general, the touch panel 73 is more easily damaged than the control circuit board 74. Therefore, in this embodiment, the holding mechanism 81 and the touch panel 73 are arranged at different positions. Thereby, it can reduce that the force of the bending direction which bends touchscreen 73 itself with respect to the touchscreen 73 acts. As a result, the possibility that the touch panel 73 is damaged can be reduced.

  Further, according to the present embodiment, the holding mechanism 81 and the control board 80 are arranged at different positions in the left-right direction 9. Thereby, the contact between the holding mechanism 81 and the control board 80 when the panel 70 is rotated can be prevented. Further, according to the present embodiment, since the space for arranging the members can be used without waste in the left-right direction 9, the multifunction device 10 can be reduced in size.
