Japanese Patent Laid-Open No. 08-152936 JP 05-27764 A

  In the rotation operation device described in Patent Document 1, a lock mechanism and a lock release mechanism are provided to increase the number of parts, and it is necessary to operate the operation lever. If the moving body is pushed, the lock mechanism may be damaged.

  The rotation operation device described in Patent Document 2 has fewer parts than the rotation operation device described in Patent Document 1, has less trouble in returning the rotation body to the first posture, and breaks the lock mechanism. There is no fear of it. However, since the rotating body is held in the second posture by the frictional force, the holding force for holding the rotating body in the second posture tends to vary among individuals, and the holding force is not stable. Further, since it is conceivable that the frictional force is reduced due to wear of the rotating shaft, the frictional force must be set large in advance, and a large force is required to rotate the rotating body. .

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a mechanism that can stabilize the holding force for holding the rotating body and can easily rotate the rotating body. There is to do.

  (1) The rotation operation device of the present invention includes an apparatus main body, a rotation body, a link member, a stopper, a support portion, a first urging member, and a contact portion. The rotating body has a first surface provided with an operation unit for receiving a push operation and a second surface opposite to the first surface, and is rotatable with respect to the first axis. The main body is supported by the main body, and the posture is changed to a first posture that lies down on the main body of the device and a second posture that stands up from the main body of the device by rotation about the first shaft. In the link member, a first member and a second member disposed on the second surface side of the rotating body are coupled so as to be rotatable relative to a second axis along the first axis. In addition, the link member is connected to the rotating body so that the first member can rotate on a third axis along the first axis, and the second member is connected to the device on a fourth axis along the first axis. The first member is erected from the second surface of the rotating body in the second posture and pivoted with respect to the second shaft and the third shaft. A third posture in which one member is opened with respect to the second member, and the first member falls to the second surface of the rotating body in the first posture, and the first member is the second member. The posture is changed to a closed fourth posture. The stopper abuts against the link member in the third posture and stops relative rotation between the first member and the second member. The support portion includes a first position where the fourth shaft provided in the second member of the link member is inserted and the fourth shaft of the link member in the fourth posture is positioned, and the first position. A long hole or groove having both ends at a second position separated from the position is provided. The first biasing member biases the second member from the second position side to the first position side. The contact portion is a position on the opposite side of the first shaft with respect to the second member of the link member in the third posture, and slides from the first position toward the second position. It arrange | positions in the position where the said 2nd member made contact | abuts. In the third posture, the link member includes the first straight line connecting the second axis and the third axis, and the second straight line connecting the second axis and the fourth axis. The opening angle that is the angle opposite to the first axis is 180 degrees or more, and in the fourth posture, the opening angle is less than 180 degrees. The support portion has an obtuse angle of an intersection angle, which is an angle on the contact portion side, among angles formed by the second straight line in the third posture and the third straight line connecting the first position and the second position. The fourth shaft is supported so as to be slidable and rotatable between the first position and the second position.

  When the rotating body is in the first posture, the link member is in a closed fourth posture in which the opening angle is less than 180 degrees and the first member falls on the second surface of the rotating body. When the rotating body is rotated from the first position to the second position, the first member connected to the rotating body is separated from the support portion. The first member pulled away from the support portion and the second member held by the support portion are relatively rotated on the second shaft. The link member is opened by the relative rotation of the first member and the second member. Further, the first member is rotated with respect to the third axis by the rotation of the rotating body, and stands from the second surface of the rotating body. When the rotating body is in the second posture, the link member is in a third posture in which the opening angle is 180 degrees or more and the first member is erected from the second surface of the rotating body. When the link member is in the third posture, the stopper comes into contact with the link member, and the relative rotation of the first member and the second member in the opening direction of the link member is stopped. The link member in the third posture opened at an opening angle of 180 degrees or more does not close when pressed by the user in the operation unit, and holds the rotating body in the second posture.

  When the rotating body in the second posture is pushed by the user from the first surface side with a force larger than the urging force of the first urging member, the fourth axis of the link member held at the first position becomes the second position. Slide towards. The 2nd member slid with the 4th axis contacts the contact part. The second member is slid and abuts against the abutting portion, thereby rotating relative to the first member on the second axis. That is, the link member starts to close. When the opening angle of the link member is less than 180 degrees, the link member is further closed by the force by which the user pushes the first member through the rotating body and the force by which the first urging member urges the second member, and the rotating body is When the posture returns to the first posture, the posture is returned to the fourth posture. As described above, when the rotating body is pushed with an urging force equal to or less than the urging force of the first urging member, the rotating body is held in the second posture and has a force larger than the urging force of the first urging member. When the rotating body is pushed, the rotating body is returned from the second posture to the first posture.

  In the rotation operation device of the present invention, since the holding force that can hold the rotating body in the second posture is determined by the urging force of the first urging member, compared to the conventional configuration in which the rotating body is held by the frictional force, The variation of the holding force can be reduced and the magnitude of the holding force can be stabilized. Further, the urging force of the first urging member becomes a resistance of the user pushing the rotating body only until the opening angle becomes less than 180 degrees, and the rotating body rotates in a direction from the first posture to the second posture. When it is moved, it only holds the fourth shaft of the second member in the first position, and does not become a resistance of the user. Therefore, the user can easily rotate the rotating body between the first posture and the second posture.

  (2) The first member and the second member are each formed in a plate shape having a width over both ends in the direction along the first axis of the rotating body, and the first member It may be connected to the rotating body at both ends. The strength of the link member can be further increased by forming the first member and the second member in a plate shape and connecting them to the rotating body at both ends of the first member. Therefore, even when a large force is applied to the rotating body, such as when the user holds the rotating body and lifts the entire rotation operating device together with the apparatus main body, the damage of the link member can be suppressed. In addition, since the first member and the second member are formed to have a width that extends over both ends of the rotating body in the above-described direction, the link member covers the inside of the apparatus main body when the rotating body is in the second posture. be able to.

  (3) The abutment portion may be provided with a pair that abuts against both end portions of the second member in a direction along the second axis. Since the pair of abutting portions abuts on both ends of the second member, the second member does not twist when the abutting portion abuts on the first member. As a result, the slidability when the rotating body is returned from the second posture to the first posture is improved.

  (4) The first member may be connected to a rotating tip portion of the rotating body. The rotating body is supported by the link member at the rotating tip. Therefore, the rotating body pushed by the user in the operation unit can be securely held in the second posture.

  (5) The operation unit may be provided in a region that is within a width range of the link member in a direction along the first axis of the rotating body. The rotating body pressed by the user in the operation unit can be reliably held in the second posture by the link member.

  (6) The contact portion may be provided with an arcuate convex surface that contacts the second member. The second member to be slid becomes easy to slide on the contact portion. As a result, the slidability when the rotating body is returned from the second posture to the first posture is improved.

  (7) The rotation operation device of the present invention may further include a second urging member that urges the link member in a direction from the fourth posture to the third posture. By providing the second urging member, the link member is not closed due to the weight of the rotating body.

  (8) In the rotation operation device according to the present invention, the rotation body is arranged in the first posture with the side on which the first shaft is provided facing up, and the rotation operation device is covered based on a signal input from the rotation operation device. You may grasp | ascertain as an image recording apparatus provided with the printer part which performs the image recording to a recording medium.

  In the present invention, since the holding force capable of holding the rotating body in the second posture is determined by the urging force of the first urging member, the holding force can be stabilized by reducing the variation of the holding force among individuals, Further, the urging force of the first urging member becomes the resistance of the user who rotates the rotating body only until the opening angle becomes less than 180 degrees, and the posture of the rotating body is changed from the first posture to the second posture. Since it does not become a user's resistance, the rotating body can be easily rotated.

The contact pieces 93 and 94 correspond to contact portions. The convex surface 95 corresponds to a convex surface.

[Operation]
Below, operation | movement of the operating device 13 is demonstrated. Note that the pair of left and right members will be described using the reference numerals of the right members. As shown in FIG. 4A, when the rotating body 40 is in the first posture, the link member 17 is in the fourth posture. In the fourth posture, the link member 17 is in a closed posture and is lying on the second surface 43 of the rotating body 40.

  When the rotating body 40 in the first posture is rotated around the central axis of the first rotating shaft 44 in the second rotation direction 32, the third rotation of the first member 50 held by the rotating body 40 is performed. The shaft 55 is rotated around the central axis of the first rotation shaft 44 together with the rotating body 40. Then, the link member 17 in the closed posture is opened by relatively rotating the first member 50 and the second member 60 around the central axis of the second rotation shaft 53. Further, the first member 50 of the link member 17 is rotated around the central axis of the third rotating shaft 55 and rises from the second surface 43 of the rotating body 40. When the rotating body 40 is in the second posture shown in FIG. 4B, the link member 17 is in an open posture and stands up from the second surface 43 of the rotating body 40. That is, the link member 17 is in the third posture.

  The link member 17 in the third posture is opened at a maximum opening angle α <b> 1 of 180 degrees or more and stands from the second surface 43 of the rotating body 40. Therefore, the link member 17 in the third posture maintains the third posture without closing when the user performs a pressing operation on the touch panel 46 (FIG. 2A) of the rotating body 40 in the second posture. To do. As a result, the link member 17 in the third posture can hold the rotating body 40 in the second posture.

  When the rotating body 40 is pushed from the first surface 42 side with a force larger than the urging force of the first coil spring 91 and the second coil spring 92 (FIG. 2B), a long hole is formed so that the crossing angle β becomes an obtuse angle. Since 71 is provided, the second member 60 is slid in a direction from the first end 72 of the elongated hole 71 toward the second end 73 (backward and obliquely downward). The slid second member 60 comes into contact with the contact piece 93 provided below and slides on the convex surface 95 of the contact piece 93. The second member 60 slides rearward and obliquely downward and is supported by the contact piece 93, so that the second member 60 is opposite to the first rotation direction 31 (FIG. 3B) with the contact piece 93 as a fulcrum. It is turned in the direction. That is, the link member 17 opened at the maximum opening angle α1 starts to close.

  As shown in FIG. 4C, when the opening angle α of the link member 17 that has started to close becomes an opening angle α2 of less than 180 degrees, the link member 17 causes the user to press the rotating body 40 and the first biasing force. The member 91 is further closed by the force that urges the second member 60, and assumes a fourth posture. That is, the rotating body 40 returns from the second posture to the first posture.

[Effect of the embodiment]
As described above, as long as the rotating body 40 in the second posture is not pushed from the first surface 42 side with a force larger than the urging force of the first coil spring 91 and the second coil spring 92, the rotating body 40 is connected to the link member 17. Is held in the second posture. That is, the holding force capable of holding the rotating body 40 in the second posture is determined by the biasing force of the first coil spring 91 and the second coil spring 92. Therefore, compared with the structure which hold | maintains the rotary body 40 with a frictional force, the dispersion | variation in the said holding force between individuals can be reduced, and the magnitude | size of the said holding force can be stabilized.

  Further, the urging force of the first coil spring 91 and the second coil spring 92 becomes the resistance of the user pushing the rotating body 40 only until the opening angle α is less than 180 degrees. Further, when the rotating body 40 is rotated from the first posture to the second posture, the first coil spring 91 and the second coil spring 92 move the fourth rotating shafts 63 and 64 of the second member 60. It is only held at the first ends 72 and 82 of the long holes 71 and 81, and does not become a resistance of the user who rotates the rotating body 40. Therefore, the user can easily rotate the rotating body 40 between the first posture and the second posture.

  Further, since the first member 50 and the second member 60 of the link member 17 are each formed in a plate shape having substantially the same width as the width in the left-right direction 9 of the rotating body 40, the rotating body 40 is set to the second posture. The inside of the housing 14 can be covered by the link member 17 in the third posture.

  Further, since the link member 17 is connected to the rotating body 40 by the left and right third rotating shafts 55, 56, the link member 17 is connected to the rotating body 40 only at one end in the left-right direction 9, or in the left-right direction 9. Sufficient strength can be ensured as compared with the configuration in which the rotating body 40 is connected only at the center. Therefore, even when the user lifts the image recording apparatus 10 with the rotating body 40, the risk of damaging the link member 17 can be reduced.

  Further, since the pair of left and right contact pieces 93 and 94 contact the left and right ends of the second member 60, the second member 60 is twisted when the rotating body 40 is returned from the second position to the first position. In other words, the slidability of the rotating body 40 due to the twist of the second member 60 does not deteriorate. As a result, the usability of the operation device 13 is improved.

  Further, since the contact pieces 93 and 94 are provided with arcuate convex surfaces 95 that come into contact with the second member 60, the second member 60 can easily slide on the contact pieces 93 and 94, and the second posture The slidability of the rotating body 40 when returning to the first posture is further improved.

  Further, as shown in FIG. 2A, the touch panel 46 is disposed at the center of the rotating body 40 in the left-right direction 9, and the link member 17 is connected to the rotating body 40 at both ends in the left-right direction 9. Has been. That is, the touch panel 46 is disposed on the inner side than the position where the link member 17 is coupled in the left-right direction 9. Therefore, the rotating body 40 pressed by the user on the touch panel 46 can be reliably held in the second posture.

The second member 60 rotated around gets over the convex portions 101 and 111 by elastic deformation. The second member 60 that has overcome the convex portions 101 and 111 is pressed by the rotating body 40 with a force equal to or less than the force by which the convex portions 101 and 111 are elastically deformed, such as when the user presses the touch panel 46 (FIG. 2A). When it is done, the rotating body 40 is held. When the rotating body 40 is further rotated in the second rotation direction 32 (FIG. 4A) by the user, the second member 60 has the convex portions 102 and 112, the convex portions 103 and 113, and the convex portions 104 and 114. Get over in order. After the second member 60 gets over the convex portions 104 and 114, the rotating body 40 assumes the second posture with the maximum opening angle α1 (FIG. 4B). Therefore, the rotating body 40 is supported by the holding members 100 and 110 at three different opening angles until the opening angle α reaches the maximum opening angle α1.
