Description

  The present invention relates to a panel device including an input unit for performing operation input and the like, and an image recording apparatus including the panel device.

  For example, an image recording apparatus is known in which the tilt of the operation panel is variable so that the user can easily perform an input operation on the operation panel (see Patent Documents 1 and 2). In such an image recording apparatus, an operation panel is provided on the main body of the image recording apparatus so as to be rotatable around a horizontal axis, for example, and the operation panel can be fixed at various angular positions.

  However, in the above-described conventional image recording apparatus, a lever operation for releasing the fixed state of the operation panel, etc., when performing a rotation operation for rotating the operation panel fixed at each angular position to another angular position, etc. Need to do. For this reason, if the user does not notice the presence of the lever, it is difficult for the user to rotate the operation panel by himself.

JP 2007-334157 A JP 2008-6625 A

  As a method of solving the above inconvenience, the panel is not completely fixed at each angular position, but the rotation of the panel is limited by a resistance force that allows an input operation at each angular position. On the other hand, when a large force exceeding the resistance force is applied in the rotation direction of the panel, a configuration is conceivable in which the panel is supported by the force so that the angular position can be changed. Hereinafter, supporting the panel in such a manner is referred to as “semi-fixed support” or “semi-fixed support” for convenience of explanation. However, when the operation panel is supported semi-fixed, it may be difficult to suppress the panel from shaking or tilting when a button operation or the like is performed on the operation panel. As a result, it is conceivable that the good operation feeling of the operation panel is impaired.

  The present invention has been made in view of the above circumstances, and an object thereof is to easily limit the rotation of the panel at a desired angular position in a configuration in which the panel having the input unit is rotatably supported. It is another object of the present invention to provide a panel device and an image recording apparatus that can improve the operational feeling of the input operation by the input unit and the rotation operation of the panel.

  (1) A panel device according to an embodiment of the present invention includes a main body, an input unit, a first surface provided with the input unit, and an input panel having a second surface opposite to the first surface. A support portion that is provided on the main body and rotatably supports the input panel; a first side surface that protrudes from the second surface of the input panel and intersects the second surface; An arm member having a second side surface opposite to the side surface, and a moving member provided on the main body, movable along a direction intersecting the first side surface, and capable of contacting the first side surface And a biasing member that biases the moving member toward the first side surface, and a plurality of the biasing members arranged along an arc concentric with the rotation center line of the input panel. Engaging with the moving member to limit the rotation of the input panel And an elastic member that is provided on the main body and is slidably contactable with the second side surface, and a contact position where the moving member and the engaging portion come into contact with each other and rotation of the input panel The first vertical distance from the center line is larger than the second vertical distance between the center position of the input panel in the direction orthogonal to the rotation center line and the rotation center line of the input panel.

  According to the above configuration, a plurality of moving members that are urged toward the first side surface of the arm member by the urging member and are capable of coming into contact with the first side surface are provided on the first side surface of the arm member. Engage with one of the engaging parts. Thereby, rotation of a panel can be restrict | limited in the angular position corresponding to the said engaging part. Therefore, for example, the input panel can be semi-fixed and supported by appropriately adjusting the shapes of the moving member and the engaging portion and the urging force of the urging member. Here, semi-fixed support means that the rotation of the input panel is limited by a certain resistance force at a plurality of angular positions, while a force exceeding the resistance force is applied in the rotation direction of the input panel. This refers to supporting the panel so that the angular position of the input panel can be changed.

  Further, the elastic member is brought into sliding contact with the second side surface opposite to the first side surface where the moving member and the engaging portion engage with each other, whereby a force exceeding the limit due to the engagement between the moving member and the engaging portion is applied to the panel. In addition to the rotation direction, the operational feeling of the rotation operation for rotating the input panel can be improved.

  Furthermore, when the first vertical distance is larger than the second vertical distance, the contact position where the moving member and the engaging portion abut can be positioned relatively close to the rotation tip of the input panel. it can. For example, as compared with the case where the contact position is adjacent to the rotation center line, the input panel can be semi-fixed and stably supported by a relatively small biasing force of the biasing member. Therefore, it is easy to suppress shaking and tilting of the panel when an input operation is performed on the input panel, and it becomes easy to improve the operational feeling of the input operation. In addition, when an input operation is performed near the left and right ends of a general horizontally long input panel, it is easy to suppress the panel from shaking or tilting. It is also easy to improve the operational feeling of the input operation.

  (2) Preferably, in the panel device, the first convex portion or the first concave portion provided in one of the main body and the arm member, extending in an arc shape around the rotation center line, and the above A second recess or a second protrusion is provided on the other of the main body and the arm member, and fits with the first protrusion or the first recess.

  According to the above configuration, by the fitting of the first convex portion or the first concave portion and the second concave portion or the second convex portion, the positional relationship between the second side surface and the elastic member, and the first side surface and the moving member. The positional relationship can be defined stably. By defining the positional relationship between the first side surface and the moving member, it is possible to stably limit the rotation of the panel. By defining the positional relationship between the second side surface and the elastic member, when a rotation operation for rotating the panel is performed in the vicinity of the left and right ends of a general horizontally long input panel In addition, it is possible to prevent the frictional force between the elastic member and the second side surface from changing by rotating the panel around the axis intersecting the rotation center line. Therefore, it is possible to prevent the frictional force from increasing and the panel from becoming difficult to rotate, or the frictional force from decreasing to prevent a favorable operational feeling of the rotational operation from being obtained.

  (3) Preferably, in the panel device, the first convex portion and the second concave portion, or the first concave portion and the second convex portion are closer to the second side surface than the first side surface. Has been placed.

  According to the above configuration, it is particularly easy to define the positional relationship between the second side surface and the elastic member, and the elastic member and the second side surface are rotated by rotating the panel around the axis intersecting the rotation center line. It is easy to prevent a problem that the frictional force fluctuates between the two.

  (4) Preferably, in the panel device, the input unit is input by a user's pressing, and the input unit disposed at a position closest to the rotation destination unit on the input panel and the rotation unit are input. The third vertical distance from the moving center line is not more than the first vertical distance.

  According to the above configuration, when the input unit is an input unit to be pressed such as a push button or a touch panel, a problem that the panel is shaken or tilted by pressing the input unit by the user is applied to the smaller biasing member. It can be suppressed by power.

  (5) Preferably, in the panel device, the biasing member is a compression spring.

  According to the above configuration, for example, compared to a case where the biasing member is a torsion coil spring (torsion bar spring), it is easy to adjust the biasing force that biases the moving member toward the arm member. Thereby, the rotation of the panel can be stably limited at each angular position. In addition, it is easy to adjust the force with which the arm member comes into contact with the elastic member, and it is also easy to adjust the frictional force between them. Therefore, it becomes easy to obtain a good operational feeling of the rotation operation of the input panel.

  (6) Preferably, in the panel device, the input panel has a shape in which a dimension in a direction along the rotation center line is longer than a dimension in a direction orthogonal to the rotation center line.

  According to the above configuration, when an input operation and a rotation operation are performed near the end in the direction along the rotation center line, a large moment for rotating the panel around the axis intersecting the rotation center line is generated. . Even in the case where such a moment occurs, according to the present invention, it is easy to obtain a good operational feeling of the input operation and the rotation operation.

  (7) An image recording apparatus according to an embodiment of the present invention includes the panel device and a recording unit that records an image on a sheet.

  According to the present invention, in the configuration in which the panel having the input unit is rotatably supported, it is easy to limit the rotation of the panel at a desired angular position, and the input operation by the input unit and the rotation of the panel can be performed. The operational feeling of the dynamic operation can be improved.

Yes. As shown in FIG. 8, the printer housing 14 is provided with a friction member 67 that is in sliding contact with the second side surface 56 of the arm member 54.

[Engagement portion 57]
A plurality of the engaging portions 57 are arranged along an arc A1 concentric with the rotation center line L1 of the panel 70. The arc A1 is an arc in which a contact position P3 where the tip 53A of the plunger 53 contacts the engaging portion 57 is located. In a state where the distal end portion 53A of the plunger 53 is in contact with the engagement portion 57 at the contact position P3, the plunger 53 is engaged with the engagement portion 57, and the rotation of the panel 70 is restricted. The engaging portion 57 has a concave shape in which the first side surface 55 is recessed, and the first rotating direction D1 around the rotating shaft 71 (the direction from the second surface 70B of the panel 70 toward the first surface 70A). ) And a first slope 57A disposed in the first rotation direction D1 from the center in the second rotation direction D2 opposite to the center, and a second slope 57B disposed in the second rotation direction D2 from the center. Have. The engaging portion 57 has a bottom surface 57C substantially parallel to the first side surface 55 between the first inclined surface 57A and the second inclined surface 57B.

  As schematically shown in FIG. 9, the first inclined surface 57A rises from the end of the bottom surface 57C in the first rotation direction D1, and the second inclined surface 57B extends in the second rotation direction D2 of the bottom surface 57C. Standing up from the edge. The angle at which the first inclined surface 57A rises from the bottom surface 57C (acute angle θ1) is a large angle closer to a right angle than the angle at which the second inclined surface 57B (acute angle θ2) rises from the bottom surface 57C. Thereby, when the panel 70 is rotated in the second rotation direction D2, the panel 70 is more likely to be restricted by the engagement between the plunger 53 and the engagement portion 57 than in the case of rotation in the first rotation direction D1. ing. In other words, the panel 70 is difficult to rotate in the second rotation direction D2 from the first rotation direction D1. This makes it easy for the panel 70 to rotate in the second rotation direction D2 even when the user presses a key or the like on the operation key portion 72 with a relatively large force during an input operation on the first surface 70A. Can be limited to. Therefore, the semi-fixed support of the panel 70 is facilitated.

  Here, the vertical distance between the contact position P3 shown in FIG. 6 and the rotation center line L1 of the panel 70 is defined as a first vertical distance S1. The vertical distance between the center position P4 of the panel 70 in the direction orthogonal to the rotation center line L1 and the rotation center line L1 of the panel 70 is defined as a second vertical distance S2. In the panel 70, the first vertical distance S1 is larger than the second vertical distance S2. Thereby, it becomes easy to support the panel 70 stably, and it becomes easy to support the panel 70 stably by engagement with the plunger 53 and the engaging part 57. If the vertical distance between the input portion (for example, the lower end 7B of the touch panel 73 in the downward direction 7B) disposed on the panel 70 and the position closest to the rotation tip and the rotation center line L1 is the third vertical distance S3, FIG. In the state shown, the third vertical distance S3 is greater than the first vertical distance S1. However, by making the first vertical distance S1 greater than the third vertical distance S3, it is possible to improve the operational feeling when an input operation is performed at the lower end 7B of the touch panel 73. Therefore, if possible in design, for example, by changing the attachment position of the arm member 54 to the panel 70 so that the contact position P3 is located at the position of the arc A2 of the two-dot chain line, The operational feeling of the operation can be further improved.

As shown in FIG. 8, the plunger 53 is provided in the printer housing 14, and is in contact with the first side surface 55 by a groove-like support portion 69 extending along a direction orthogonal to the first side surface 55. It is supported so that it can touch. The plunger 53 is supported by the support portion 69 so as to be movable along a direction orthogonal to the first side surface 55. The plunger 53 is a rectangular tube-shaped member having a hollow portion 53C, and a compression spring 53B extending in the axial direction in a direction orthogonal to the first side surface 55 is disposed in the hollow portion 53C.

  One end of the compression spring 53B is fitted into a protrusion 69A disposed in the hollow portion 53C, and the other end is projected upward 7A by a protrusion 69B provided on an end surface facing the first side surface 55 of the support portion 69. And it is positioned in the downward direction 7B, the forward direction 8A, and the backward direction 8B. In this state, the compression spring 53B urges the plunger 53 toward the first side surface 55. The plunger 53 has a shape in which the distal end portion 53 </ b> A corresponds to the concave shape of the engaging portion 57, and when the distal end portion 53 </ b> A is fitted into the engaging portion 57, the angular position corresponding to the engaging portion 57. The rotation of the panel 70 is limited. Further, the plunger 53 is moved in the left direction 9 </ b> A and the right direction 9 </ b> B in a state where the distal end portion 53 </ b> A is engaged with the engaging portion 57 by the shaft-like positioning member 68 provided so as to be able to contact the outer peripheral surface of the plunger 53. The position can be fixed.

[Friction member 67]
The friction member 67 is made of, for example, rubber (referred to as high slidability rubber) whose surface is coated with a coating that enhances slidability. As shown in FIG. 8, the friction member 67 is provided in the arm guide portion 60 and is in contact with the second side surface 56 of the arm member 54 in a slightly compressed state. The friction member 67 has a prismatic shape, and its axial direction is arranged perpendicular to the second side surface 56. When the friction member 67, which is an elastic member, is in sliding contact with the second side surface 56, rattling when the panel 70 is rotated can be suppressed, and the operational feeling of the rotation operation can be improved.

[Positioning groove 58, convex portion 59]
As shown in FIG. 7, the arm member 54 is provided in the printer housing 14 and is guided by an arm guide portion 60 that is an arc-shaped slot into which the arm member 54 can be inserted from the tip end portion. In the left direction 9A and the right direction 9B, the arm guide portion 60 protrudes in the upward direction 7A at a position corresponding to the positioning groove 58 (an example of the first recess) shown in FIG. It has a columnar convex portion 59 (an example of a second convex portion). The panel 70 rotates between the first position and the second position in a state where the convex portion 59 is fitted in the positioning groove 58. The positioning groove 58 and the convex portion 59 are disposed at a position closer to the second side surface 56 than the first side surface 55 in the left direction 9A and the right direction 9B. Thereby, even when a force is applied in the vicinity of the end portions of the panel 70 in the direction 9 </ b> A and the right direction 9 </ b> B, the rotation of the panel 70 around the axis intersecting the rotation axis 71 can be suppressed. Therefore, the fluctuation of the frictional force between the friction member 67 and the arm member 54 can be suppressed, and the operational feeling of the rotation operation of the panel 70 can be improved.

  Further, as shown in FIG. 8, the guide groove 51 extends parallel to the positioning groove 58 at a position in the right direction 9 </ b> B with respect to the positioning groove 58. The panel 70 extends in the rotational direction. As shown in FIG. 7, a contact portion 54 </ b> A is provided at an end portion of the guide groove 51 in the second rotation direction D <b> 2. The contact portion 54A protrudes into the inner space of the guide groove 51 from the bottom portion 51A of the guide groove 51 in the rotation center direction D3, and contacts the stopper 60A when the panel 70 is located at the second position. 54A is provided. When the contact portion 54A contacts the stopper 60A, the panel 70 is prevented from rotating in the first rotation direction D1 at the second position, and the panel 70 is positioned at the second position.

[Effect of the embodiment]

  According to the embodiment described above, the first vertical distance S1 shown in FIG. 6 is larger than the second vertical distance S2, so that a spring having a large urging force is not used as the compression spring 53B. The operational feeling of the input operation can be improved.

  According to the embodiment described above, the panel 70 is rotated by sliding the friction member 67 against the second side surface 56 opposite to the first side surface 55 where the plunger 53 and the engaging portion 57 are engaged. The feeling of operation can be improved.

[Modification]
In the above embodiment, the positioning groove 58 is provided in the arm member 54, and the convex portion 59 that is fitted to the arm member 54 is provided in the printer housing 14. However, the present invention is not limited thereto, and a convex portion extending in an arc shape around the rotation center line L1 may be provided in the arm member 54, while a concave portion having a shape that can sandwich the convex portion may be provided in the printer housing 14. Alternatively, the positioning groove 58 may be provided in the printer housing 14, and a convex portion that fits the positioning groove 58 may be provided in the arm member 54, and the convex portion that extends in an arc shape around the rotation center line L 1 may be provided in the printer housing 14. On the other hand, the arm member 54 may be provided with a recess having a shape capable of sandwiching the protrusion. Further, the positioning groove 58 and the convex portion 59 can be arranged at a position closer to the first side surface 55 than the second side surface 56.

  The plunger 53 may be biased toward the first side surface 55 by, for example, a torsion spring instead of the compression spring 53B.
