Description

  The present invention relates to a panel tilt mechanism and a recording apparatus.

A recording apparatus that performs recording processing on a recording medium includes, for example, an embodiment in which a recording head is provided to perform recording processing by ink jet, or an electrostatic latent image is formed on a photoreceptor, and a toner image is transferred to the recording medium to perform recording processing There is a form to implement.
The recording apparatus includes an operation panel having a display unit for displaying predetermined information and a button unit for inputting predetermined information, and a user operates the operation panel to perform desired settings and operations related to recording processing. . For example, the operation panel described in Patent Document 1 includes a panel tilt mechanism, and is configured to be able to be displaced to a posture with an arbitrary inclination angle that is easy for a user to operate.
In the panel tilt mechanism described in Patent Document 1, there is a lock mechanism in which teeth are provided on the outer peripheral surface of a tilt tooth unit, and a lever that engages with the teeth is locked to maintain an inclination angle. The lever must be unlocked in order to be displaced to a posture with an arbitrary inclination angle that is easy for the user to operate.

JP 2011-101962 A

Therefore, a panel tilt mechanism that maintains the tilt angle of the operation panel without using a lock mechanism was examined. When the holding force of the holding mechanism that holds the inclination angle is compared, the operation panel in the standing posture has less weight than the operation panel in the horizontal posture. That is, as the operation panel transitions from the standing position to the horizontal position, the weight of the operation panel is increased.
For this reason, even if the holding force of the holding mechanism that holds the tilt angle of the operation panel is constant, the operation panel's own weight is displaced depending on the tilt position of the operation panel. It turned out that there is a problem that it differs depending on the posture.
In view of this problem, an object of the present invention is to make the operation force necessary when the user displaces the tilted posture of the operation panel constant and improve the operation feeling.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

  [Application Example 1] A panel body, a pivot shaft provided on the panel body for pivoting the panel body, and a plurality of regulating portions for regulating a pivot range are provided on a side surface. A rotating body that rotates with movement, and an engaging member that engages with the restricting portion of the rotating body, and the plurality of restricting portions include a restricting surface that restricts a rotation angle of the panel body, The panel tilt mechanism according to claim 1, wherein the greater the angle of inclination of the panel body rotating about the rotation axis with respect to the vertical direction, the greater the engagement force between the restriction surface and the engagement member.

  The force to rotate due to the weight of the panel body, that is, the rotational moment, increases as the inclination angle of the panel body that rotates about the rotation axis with respect to the vertical direction increases. According to this application example, the plurality of restriction portions include restriction surfaces for restricting the rotation angle of the panel body, and the greater the inclination angle with respect to the vertical direction of the panel body that rotates about the rotation shaft, The engaging force with the engaging member is large. As a result, the inclination angle of the panel body with respect to the vertical direction increases, and even if the force (rotational moment) to rotate due to the panel body's own weight decreases, fluctuations in the operating force required to rotate the panel body The amount is small. Therefore, the user feels as if he / she is operating the panel body with a substantially constant operating force even when the tilting posture of the panel body is displaced, so that the operational feeling is improved.

  Application Example 2 In the panel tilt mechanism, the regulating surface of the rotating body has a wedge-shaped inclined surface.

  According to this application example, the rotation range and the rotation angle when the panel body rotates in the horizontal direction or the vertical direction are restricted.

  Application Example 3 In the plurality of regulating surfaces, an inclination angle formed from a side surface of the rotating body of an inclined surface in a direction in which the panel body rotates in a vertical direction is such that the inclined surface closer to the panel body has the inclination angle. The panel tilt mechanism according to claim 1, wherein the panel tilt mechanism is large.

  According to this application example, the greater the inclination angle of the panel body with respect to the vertical direction, the greater the engagement force between the restriction surface and the engagement member. As a result, the inclination angle of the panel body with respect to the vertical direction increases, and even if the force (rotational moment) to rotate due to the panel body's own weight decreases, fluctuations in the operating force required to rotate the panel body The amount is small. Therefore, the user feels as if he / she is operating the panel body with a substantially constant operating force even when the tilting posture of the panel body is displaced, so that the operational feeling is improved.

  Application Example 4 The inclined surface in the direction in which the panel body rotates in the vertical direction is inclined at a larger inclination angle from the side surface of the rotating body than the inclined surface in the direction in which the panel body rotates in the horizontal direction. The panel tilt mechanism as described above.

  When the regulating surface is engaged with the engaging member, a force (rotational moment) is applied to the inclined surface in the direction in which the panel body rotates in the vertical direction due to the weight of the panel body. On the inclined surface in the direction in which the panel body rotates in the horizontal direction, no force is applied to the panel body due to its own weight (small). According to this application example, the inclined surface in the direction in which the panel body rotates in the vertical direction rotates while suppressing the fluctuation of the operation force while allowing the panel body to be held at a predetermined angle position. Can do. On the other hand, since the inclined surface in the direction in which the panel body rotates in the horizontal direction can be operated with an operation force smaller than the operation force in which the panel body rotates in the vertical direction, the operational feeling is improved.

  Application Example 5 A recording apparatus comprising the panel tilt mechanism described above.

  According to this application example, the amount of fluctuation in the operation force necessary to rotate the panel body is small even if the inclination angle of the panel body with respect to the vertical direction changes. For this reason, the user feels that the panel body is being operated with a substantially constant operating force, so that the operational feeling of the panel tilt mechanism provided in the recording apparatus is improved.

  FIG. 3 is a perspective view of the raised panel body 10 as viewed from the back side, and shows a state where the housing cover 13 of FIG. 2 is removed and the panel body mounting portion 15 is exposed. The panel body attaching portion 15 is provided with a panel tilt mechanism 30. The panel tilt mechanism 30 includes the panel body 10, the rotating body 14, the engagement member 16, and a coiled spring member 17 as an urging member.

  The main body 101 of the panel body 10 is fixed to the support portions 102 and 103, and the support portions 102 and 103 are provided with rotating shafts 104 and 105. The panel body mounting portion 15 is provided with lower bearing portions 19 and 20 that support the lower outer peripheral surfaces of the rotating shafts 104 and 105.

In the state in which the housing cover 13 is attached to the panel body attaching portion 15 in FIG. 2, the outer peripheral surfaces of the rotating shafts 104 and 105 are sandwiched between the lower bearing portions 19 and 20 and the upper bearing portion 131. A bearing portion is configured.

  With such a configuration, the rotation shafts 104 and 105 can be rotated around the rotation fulcrum A by the bearing portion including the lower bearing portions 19 and 20 and the upper bearing portion 131. Accordingly, the panel body 10 is provided so as to be rotatable in the direction D1 and the direction D2 around the rotation fulcrum A.

  A rotating body 14 is fixed on the opposite side of the main body 101 from the touch panel 100. FIG. 4 is a perspective view of a portion provided with the panel body 10 as viewed from the back side, and shows a state where the rotating body 14 of FIG. 3 is removed. 4 is provided with bearing portions 21 and 22, and the shaft portion (not shown) of the rotating body 14 in FIG. 3 is loosely fitted to the inner peripheral surfaces 21a and 22a of the bearing portions 21 and 22. Match. With such a configuration, the rotating body 14 of FIG. 3 rotates about the rotation fulcrum A as the panel body 10 rotates.

  The engagement member 16 in FIG. 3 has a rotation shaft 160 and is provided in the panel body mounting portion 15 so as to be rotatable about directions of rotation B in directions D3 and D4. That is, the engaging member 16 pivots about the pivot point B so as to be swingable toward the rotating body 14 in a horizontal plane. An abutting portion 171 of a coiled spring member 17 as an urging member abuts on the receiving portion 161 on the surface of the engaging member 16 on the opposite side to the rotating body 14 on the free end side.

  The side of the coiled spring member 17 opposite to the contact portion 171 is fixed to a fixing portion 18 erected on the panel body mounting portion 15. The receiving portion 161 of the engaging member 16 is biased in the direction D5 by the coiled spring member 17.

  FIG. 5 is a perspective view of the portion provided with the panel body 10 as seen from the back side, and shows a state where the engaging member 16 of FIG. 3 is removed. A regulating portion 140 is provided on the side surface 14a on the engagement member 16 side in the width direction Y of the rotating body 14 in FIG. The restricting portion 140 includes a plurality of restricting surfaces 141, 142, 143, and 144 that are arranged in the circumferential direction around the rotation fulcrum A.

  On the opposite side of the receiving portion 161 (see FIG. 3) in the width direction Y of the engaging member 16 in FIG. 4, a protruding portion 162 as an engaging portion is provided. The protrusion 162 is provided at a position that can be engaged with any one of the regulation surfaces 141, 142, 143, and 144 when the rotating body 14 rotates. The inclination angle of the panel body 10 with respect to the vertical direction Z is maintained in a state in which the protrusion 162 is engaged with any one of the regulation surfaces 141, 142, 143, and 144.

  FIG. 6 is a perspective view showing the side surface 14b of the rotating body 14 and the standing portion 24 that is slidably provided. When the coiled spring member 17 urges the restricting portion 140 of the rotating body 14 via the engaging member 16 in the direction D5, a force to rotate the rotating body 14 on the horizontal plane acts.

  In the present embodiment, the standing body 24 is provided on the panel body mounting portion 15 so as to be slidable along the side surface 14 b along the side surface 14 b opposite to the engaging member 16 of the rotating body 14. Thus, when the protruding portion 162 of the engaging member 16 is biased in the direction D5 by the coiled spring member 17 against the restricting portion 140 of the rotating body 14, the standing portion 24 contacts the side surface 14b of the rotating body 14. The rotating body 14 is supported in contact. Therefore, damage to the shaft portion of the rotating body 14 and the bearing portions 21 and 22 (see FIG. 4) due to the force of rotating the rotating body 14 on the horizontal plane is suppressed. The standing portion 24 may be configured not to contact the rotating body 14 by using a spacer interposed between the bearing portion 22 and the rotating body 14.

Here, the operation force necessary for performing the operation of tilting the panel body 10 will be described.
FIGS. 7A and 7B are schematic views showing the tilt posture of the panel body 10 as viewed from the width direction Y. FIG. FIG. 7A shows a state in which the protruding portion 162 is engaged with the regulating surface 142 of the rotating body 14, and FIG. 7B shows a state in which the protruding portion 162 is engaged with the regulating surface 141 of the rotating body 14. Show.

  The rotation range E of the rotating body 14 in FIG. 7A is from the state in which the protrusion 162 is engaged with the restriction surface 144 to the state in which the protrusion 162 is engaged with the restriction surface 141. A range of angles. That is, the restricting unit 140 restricts the rotation range E of the panel body 10 fixed to the rotating body 14.

  Further, the rotation angle of the rotating body 14 is an angle until the protrusion 162 rotates from a state where it is engaged with one of the restriction surfaces 141 to 144 and shifts to a state where it is engaged with the adjacent restriction surface. A range. For example, the rotation angle F of the rotating body 14 in FIG. 7B rotates from the state in which the protrusion 162 in FIG. 7A is engaged with the regulating surface 142, and the protrusion 162 in FIG. 7B. Is a range of angles until the state shifts to the state of being engaged with the regulating surface 141. That is, the restricting unit 140 restricts the rotation angle F of the panel body 10 fixed to the rotating body 14.

  At the center of gravity G of the panel body 10 in FIG. 7A, the panel body 10 is rotated in the direction D1 in which the panel body 10 is tilted by the component force W1 in the tangential direction of the circle S around the rotation fulcrum A at its own weight W. Rotating moment that acts. Similarly, the center of gravity G of the panel body 10 in FIG. 7B is rotated in the direction D1 in which the panel body 10 is tilted by the component force W2 in the tangential direction of the circle S around the rotation fulcrum A at its own weight W. The rotational moment to be applied acts.

  As an example of the operation of tilting the panel body 10, the state shifts from the state in which the protrusion 162 is engaged with the restriction surface 142 in FIG. 7A to the state in which the protrusion 162 is engaged with the restriction surface 141 in FIG. 7B. The case where it does is demonstrated. The angle R3 with respect to the vertical direction Z of the panel body 10 when the protrusion 162 is engaged with the restriction surface 141 of FIG. 7B is the engagement of the protrusion 162 with the restriction surface 142 of FIG. It becomes larger than the angle R1 with respect to the vertical direction Z of the panel body 10 when it is in the state to perform.

  Accordingly, an angle R4 formed by the weight W2 and the component weight W2 in a state where the regulating surface 141 and the protruding portion 162 in FIG. 7B are engaged with each other is determined by the regulating surface 142 and the protruding portion 162 in FIG. Becomes smaller than an angle R2 formed by the weight W1 and the component force W1.

  Accordingly, when the rotation moment for rotating the panel body 10 in the direction D1 by the own weight W is compared, the rotation moment due to the own weight W in the state where the restricting surface 141 and the protrusion 162 in FIG. Is larger than the rotational moment due to its own weight W in the state where the restricting surface 142 and the protrusion 162 in FIG.

  The restricting surface 141 is formed at a position closer to the panel body 10 than the restricting surface 142 in the circumferential direction around the pivot fulcrum A. As described with reference to FIGS. 7A and 7B, the inclination angle of the panel body 10 with respect to the vertical direction Z increases as the restriction surface that engages the protrusion 162 is closer to the panel body 10. Rotational moment to rotate the panel body 10 in the direction D1 due to its own weight W increases.

  FIG. 8A is a cross-sectional view of the portion where the protrusion 162 engages with the restriction surface 142 from the back side in the depth direction X in the state where the protrusion 162 of FIG. FIG. The regulating surface 142 includes an upper inclined surface 142a inclined at an angle Q1 with respect to a side surface 14a extending in the vertical direction Z of the rotating body 14, and a lower inclined surface 142b inclined at an angle Q2 with respect to the side surface 14a of the rotating body 14. The restricting surface 142 is formed in a wedge shape by the upper inclined surface 142a and the lower inclined surface 142b.

  The upper surface 162a of the protrusion 162 abuts on the upper inclined surface 142a, and the lower surface 162b of the protrusion 162 abuts on the lower inclined surface 142b.

  FIG. 8B is a cross-sectional view of the portion where the protrusion 162 engages with the restriction surface 141 from the back side in the depth direction X in the state where the protrusion 162 of FIG. 7B engages with the restriction surface 141. FIG. The regulating surface 141 includes an upper inclined surface 141a inclined at an angle Q3 with respect to a side surface 14a extending in the vertical direction Z of the rotating body 14, and a lower inclined surface 141b inclined at an angle Q4 with respect to the side surface 14a of the rotating body 14. Consists of The regulating surface 141 is formed in a wedge shape by the upper inclined surface 141a and the lower inclined surface 141b.

  The upper surface 162a of the protruding part 162 is in contact with the upper inclined surface 141a, and the lower surface 162b of the protruding part 162 is in contact with the lower inclined surface 141b.

  Similarly, the restricting surfaces 143 and 144 are respectively composed of an upper inclined surface and a lower inclined surface that are inclined with respect to the side surface 14a of the rotating body 14, and the restricting surfaces 143 and 144 are the upper inclined surface and the lower side, respectively. It is formed in a wedge shape by the inclined surface. In a state where the protrusion 162 is engaged with the restriction surface 143 or the restriction surface 144, the upper surface 162a of the protrusion 162 comes into contact with the upper inclined surface, and the lower surface 162b of the protrusion 162 comes into contact with the lower inclined surface.

  When the operation of tilting the panel body 10 is performed in a state where the projecting portion 162 in FIG. 8A is engaged with the regulating surface 142, the rotating body 14 rotates in the direction D1, and the projecting portion 162 is pressed against the upper inclined surface 142a. Then, it moves in the direction opposite to the direction D5 and moves relatively in the direction D2 along the upper inclined surface 142a. When the rotating body 14 further rotates in the direction D1, the projecting portion 162 gets over the upper inclined surface 142a and slides on the side surface 14a. That is, the engagement state between the protrusion 162 and the restriction surface 142 is released.

  Similarly, when an operation of tilting the panel body 10 is performed in a state where the projecting portion 162 in FIG. 8B is engaged with the regulating surface 141, the rotating body 14 rotates in the direction D1, and the projecting portion 162 has an upper inclined surface. It is pressed by 141a and moves in the direction opposite to the direction D5, and moves relatively in the direction D2 along the upper inclined surface 141a, and the protruding portion 162 gets over the upper inclined surface 141a and slides on the side surface 14a. That is, the engagement state between the projecting portion 162 and the restricting surface 141 is released.

  An inclination angle Q3 with respect to the vertical direction Z of the upper inclined surface 141a in the regulating surface 141 in FIG. 8B is larger than an inclination angle Q1 with respect to the vertical direction Z of the upper inclined surface 142a in the regulating surface 142 in FIG. Therefore, when the operation of tilting the panel body 10 is performed and the rotating body 14 rotates in the direction D1, the upper surface 162a of the protrusion 162 in FIG. 8B is relatively pressed in the direction D2 while being pressed by the upper inclined surface 141a. The force for moving and overcoming the upper inclined surface 141a is larger than the force for the upper surface 162a of the protrusion 162 of FIG. 8A to get over the upper inclined surface 142a relatively.

  That is, when the panel body 10 is rotated in the direction D1 to tilt down, the engaging force in the state where the restricting surface 141 and the protruding portion 162 in FIG. 8B are engaged with the restricting surface 142 in FIG. It is larger than the engaging force in the state in which the part 162 is engaged. As described above, the upper inclined surface 141a of the regulating surface 141 is located closer to the panel body 10 than the upper inclined surface 142a of the regulating surface 142 in the circumferential direction.

  As described with reference to FIGS. 8A and 8B, the upper inclined surfaces of the plurality of regulating surfaces 141 to 144 are such that the inclination angle with respect to the vertical direction Z increases as the upper inclined surface is closer to the panel body 10. Formed. Therefore, the engagement force with the protrusion 162 on the restriction surfaces 141 to 144 increases as the restriction surface is located closer to the panel body 10 with the protrusion 162.

  The operation force necessary for performing the operation of tilting the panel body 10 needs to exceed the force obtained by subtracting the rotational moment due to the own weight W from the engagement force with which the protrusion 162 engages with the restriction surface. In the present embodiment, when the panel body 10 is rotated in the direction D1 to be tilted, the protrusions 162 and the panel body 10 are tilted as the panel body 10 is tilted, that is, the inclination angle (R1, R3) with respect to the vertical direction Z of the panel body 10 is increased. Engagement force with the regulation surface increases.

  Therefore, when the panel body 10 is rotated in the direction D1 to tilt, even if the rotational moment due to its own weight W increases, the engaging force with which the protrusion 162 engages with the restriction surface increases, and the panel body 10 is tilted. The amount of fluctuation in the required operating force is small. Therefore, the user feels as if the panel body 10 is tilted with a substantially constant operation force, and the operational feeling is improved.

  As a comparative example, if the engaging force with which the projecting portion 162 engages with the regulating surface is constant, the rotational moment due to its own weight W increases as the panel body 10 is tilted, so the user tilts the panel body 10. Therefore, the operating force required for this is reduced. For this reason, the panel body 10 feels heavy when it is most raised, and the panel body 10 feels lighter as the panel body 10 is tilted down, and the operational feeling is lowered.

Next, the operation force necessary for performing the operation of raising the panel body 10 will be described.
As an example of the operation for raising the panel body 10, the state in which the protruding portion 162 engages with the regulating surface 141 in FIG. 7B shifts to the state in which the protruding portion 162 engages with the regulating surface 142 in FIG. The case where it does is demonstrated.

  An inclination angle Q2 with respect to the vertical direction Z of the lower inclined surface 142b in the regulating surface 142 in FIG. 8A is larger than an inclination angle Q4 with respect to the vertical direction Z of the lower inclined surface 141b in the regulating surface 141 in FIG. . Therefore, when the rotating body 14 rotates in the direction D2 while being biased in the direction D5 by the coiled spring member 17 (see FIG. 3) (when rotated in the direction D2 in which the panel body 10 is raised), FIG. The force that the lower surface 162b of the projecting portion 162 in FIG. 8A tries to get over the lower inclined surface 142b is relatively larger than the lower surface 162b of the protruding portion 162 in FIG. 8B gets over the lower inclined surface 141b relatively. It becomes larger than the power to try.

  That is, when rotating in the direction D2 in which the panel body 10 is raised, the engaging force in the state where the restricting surface 142 and the protruding portion 162 in FIG. 7A are engaged with the restricting surface 141 in FIG. It becomes larger than the engaging force in the state in which the part 162 is engaged.

  The operating force required to rotate the panel body 10 in the direction D2 to be raised needs to exceed the force obtained by adding the rotational moment due to its own weight W to the engaging force with which the protrusion 162 engages with the regulating surface. It is. As described with reference to FIGS. 7A and 7B, the rotational moment decreases as the panel body 10 is raised.

  In the present embodiment, as described with reference to FIGS. 8A and 8B, the lower inclined surface in which the plurality of lower inclined surfaces 141b and 142b are located farther (away from) the panel body 10, The inclination angles Q2 and Q4 with respect to the vertical direction Z are large, and the engaging force with which the protrusion 162 engages with the lower inclined surfaces 141b and 142b is increased.

  As a result, when the panel body 10 is rotated in the direction D2 in which the panel body 10 is raised, even if the rotational moment due to its own weight W is reduced, the engagement force with which the protruding portion 162 engages with the restriction surface is increased. Fluctuation amount of operating force required for operation is small. For this reason, the operating force when the user raises the panel body 10 feels substantially constant, so that the operational feeling is improved.

  As a comparative example, if the engaging force with which the projecting portion 162 engages with the regulation surface is constant, the rotational moment due to its own weight W decreases as the panel body 10 is raised, so that the user raises the panel body 10. The operation force becomes smaller as it goes. Therefore, the user feels lighter as the panel body 10 is raised, and the operational feeling is lowered.

  Next, the case where the inclination angle with respect to the vertical direction Z is compared between the upper inclined surface and the lower inclined surface of the regulating surface will be described.

  When the protrusion 162 in FIGS. 8A and 8B is engaged with the regulating surfaces 141 and 142, the upper surface 162a of the protrusion 162 receives a rotational moment due to its own weight W from the upper inclined surfaces 141a and 142a. Take it. On the other hand, the lower surface 162b of the protrusion 162 is not subjected to a rotational moment due to its own weight W from the lower inclined surfaces 141b and 142b. Alternatively, the rotational moment applied from the lower inclined surfaces 141b and 142b by the own weight W is smaller than the rotational moment applied from the upper inclined surfaces 141a and 142a by the own weight W.

  8A, the inclination angle Q1 of the upper inclined surface 142a with respect to the vertical direction Z is larger than the inclination angle Q2 of the lower inclined surface 142b with respect to the vertical direction Z. 8B, the inclination angle Q3 of the upper inclined surface 141a with respect to the vertical direction Z is larger than the inclination angle Q4 of the lower inclined surface 141b with respect to the vertical direction Z. Similarly, in the regulating surfaces 143 and 144, the inclination angle of the upper inclined surface with respect to the vertical direction Z is larger than the inclination angle of the lower inclined surface with respect to the vertical direction Z.

With such a configuration, the inclination angle of the lower inclined surfaces 141b and 142b with respect to the vertical direction Z can be reduced, and the engagement force when the panel body 10 is raised can be reduced. Thereby, when the panel body 10 is raised in the direction D2, it is suppressed from feeling heavy because the engagement force is large.
In addition, since the function which hold | maintains the panel body 10 in the position of a predetermined angle is mainly an upper side inclined surface, with respect to the direction rotated in a horizontal direction (direction to incline), it is the weight of the panel body 10 as it rotates. Although it becomes heavy, a plurality of lower inclined surfaces may be set to the same inclination angle.

  As described above, the panel tilt mechanism 30 of FIG. 3 provided in the multifunction machine 1 described in the present embodiment includes the panel body 10, the rotation shafts 104 and 105 provided on the panel body 10, and rotating the panel body 10. The rotating body 14 that has a restricting portion 140 that restricts the rotation range E (see FIG. 7A) on the side surface 14 a and rotates with the rotation of the rotating shafts 104 and 105, and the restricting portion 140 of the rotating body 14. The restricting portion 140 includes a plurality of restricting surfaces 141 to 144 for restricting the rotation angle F of the panel body 10 (see FIG. 7B), and the rotation shaft. As the inclination angles R1 and R3 with respect to the vertical direction Z of the panel body 10 rotating around 104 and 105 are larger, the engagement force between the restriction surfaces 141 to 144 and the engagement member 16 is larger.

  As described with reference to FIGS. 7A and 7B, the panel body 10 rotates about the rotation shafts 104 and 105, that is, the force to rotate due to the weight W of the panel body 10, that is, the rotation moment. The larger the inclination angles R1 and R3 with respect to the vertical direction Z of 10, the larger. According to the present embodiment, the restricting portion 140 includes a plurality of restricting surfaces 141 to 144 that restrict the rotation angle F of the panel body 10, and the vertical direction of the panel body 10 that rotates about the rotation shafts 104 and 105. The greater the inclination angles R1, R3 with respect to Z, the greater the engagement force between the restricting surfaces 141-144 and the engagement member 16. Thereby, even if the inclination angle R1, R3 with respect to the vertical direction Z of the panel body 10 changes, the amount of fluctuation | variation is small for the operation force required in order to rotate the panel body 10. FIG. Therefore, the user feels as if the panel body 10 is being operated with a substantially constant operating force even when the inclination posture of the panel body 10 is displaced, and thus the operational feeling is improved.

  Further, the regulation surfaces 141 and 142 of the rotating body 14 have upper inclined surfaces 141a and 142a as wedge-shaped inclined surfaces, and lower inclined surfaces 141b and 142b. Thereby, the rotation range E and the rotation angle F when the panel body 10 rotates in the horizontal direction (direction D1 in which the panel body 10 is tilted) or the vertical direction Z (direction D2 in which the panel body 10 is raised) are regulated.

  In addition, an inclination angle formed by the side surface 14a of the rotating body 14 of the upper inclined surfaces 141a and 142a, which are inclined surfaces in the direction in which the panel body 10 rotates in the vertical direction Z (direction D2 side), in the plurality of regulating surfaces 141 and 142. Q3 and Q1 have a larger inclination angle as the inclined surface is closer to the panel body 10.

  With this configuration, when the panel body 10 is rotated in the direction D <b> 1 to be tilted, the engagement force becomes larger as the panel body 10 is engaged with the inclined surface closer to the panel body 10. As a result, the inclination angles R1 and R3 of the panel body 10 with respect to the vertical direction Z are increased, and the panel body 10 is rotated even if the force (rotation moment) to rotate due to its own weight W is reduced. Therefore, the fluctuation amount of the operation force necessary for this is small. Therefore, the user feels as if the panel body 10 is being operated with a substantially constant operating force even when the inclination posture of the panel body 10 is displaced, and thus the operational feeling is improved.

  Further, the inclination angles Q3 and Q1 of the upper inclined surfaces 141a and 142a with respect to the side surface 14a of the rotating body 14 are larger than the inclination angles Q4 and Q2 of the lower inclined surfaces 141b and 142b with respect to the side surface 14a of the rotating body 14. That is, on the regulating surfaces 141 and 142, the upper inclined surfaces 141a and 142a, which are inclined surfaces in the direction in which the panel body 10 rotates in the vertical direction Z (direction D2 side), are directions in which the panel body 10 rotates in the horizontal direction. It is inclined at a larger inclination angle from the side surface 14a of the rotator 14 than the lower inclined surfaces 141b and 142b which are inclined surfaces in the direction D1.

  When the restricting surfaces 141 and 142 are engaged with the engaging member 16, a force (rotational moment) is applied to the upper inclined surfaces 141a and 142a to rotate due to the weight W of the panel body 10, The lower inclined surfaces 141b and 142b are not applied with a force (small) to rotate due to their own weight W of the panel body 10.

  Since the inclination angles Q3, Q1 of the upper inclined surfaces 141a, 142a are larger than the inclination angles Q4, Q2 of the lower inclined surfaces 141b, 142b, the lower inclined surfaces 141b, 142b and the engaging member 16 are engaged. Since the resultant force can be reduced, the operating force when rotating in the direction D2 in which the panel body 10 is raised is reduced and the operational feeling is improved.

  In the present embodiment, the panel tilt mechanism 30 is provided in the multi-function device 1 which is an example of a recording device, but may be provided in an electronic device.
