  Reference numeral 3 denotes a storage medium insertion unit for inserting a storage medium (not shown) in which image data and the like are stored. The inkjet multifunction peripheral 1A is stored in the storage medium inserted in the storage medium insertion unit 3. The image data is configured as a so-called stand-alone printer that can independently perform inkjet recording without using an external computer.

  A tilt panel unit 10A as a tilt portion is provided at the central portion on the front side of the apparatus. The tilt panel unit 10A includes an information display unit 11 including a liquid crystal monitor that displays various types of information such as a preview image and a user interface, an operation setting unit 12 including a plurality of touch buttons for performing various settings, It has.

  The tilt panel unit 10A is provided so as to be able to rotate (tilt) with respect to the apparatus main body 1a of the inkjet multifunction peripheral 1A via a tilt device 20 to be described later. The tilt angle of the tilt panel unit 10A is shown in FIG. It is held at an angle as shown, and can be held at an arbitrary angle with good visibility and operability for the user.

  In FIG. 1, reference numeral 21 denotes a push button constituting the tilt device 20, and the tilt panel unit 10 </ b> A is tilted from the vertical posture in FIG. 1 to the tilt posture as shown in FIG. As a result, the tilt angle holding state is released, and the vertical posture of FIG. 1 can be restored.

Next, the tilt device 20 will be described in detail with reference to FIGS.
The tilt device 20 according to the present embodiment includes a support member 22 provided in a fixed state on the printer main body side, a ratchet member 23 attached to a shaft 22a of the support member 22, and a frame 14A constituting a base of the tilt panel unit 10A. The movable member 24 and the push button 21 are provided so as to be slidable. A pressing spring 25 is provided between the movable member 24 and the push button 21, and a pressing spring 26 is provided between the movable member 24 and the frame 14A.

  The shaft 22a of the support member 22 is a shaft that forms the rotation center of the tilt panel unit 10A. The ratchet member 23 that is fixedly attached to the shaft 22a is a “tooth portion” along the outer periphery of the cylindrical member. As a plurality of ratchet teeth 23a.

  The movable member 24 has a hole 24a into which the ratchet member 23 is loosely inserted, and includes an engaging claw 24b inside the hole 24a. The movable member 24 has a cylindrical portion 24c, and this cylindrical portion 24c is loosely inserted into the holder 15 formed on the frame 14A.

  The movable member 24 is slidable in the vertical direction of FIGS. 3 to 5, that is, in the stroke direction of the push button 21 when the cylindrical portion 24 c is loosely inserted into the holder 15. ), The engagement claw 24b is switched between engagement and disengagement with the ratchet teeth 23a.

  Further, when the ratchet member 23 is loosely inserted into the hole 24a, the movable member 24 can be rotated about the ratchet member 23 (shaft 22a), that is, the tilt panel unit 10A can be rotated about the ratchet member 23 (shaft 22a). It can be rotated.

  The push button 21 is provided with a protrusion 21a on the side, and when the protrusion 21a abuts the inner surface of the tilt panel unit 10A on the regulating surface (indicated by reference numeral Sr in FIG. 6), the upper limit position of the vertical movement stroke is set. It has become fixed. The lower limit position of the vertical movement stroke of the push button 21 is such that when the push button 21 is pushed in, the lower end portion of the cylindrical portion 24c of the movable member 24 contacts the inner bottom surface 15a of the holder 15, and the push button 21 is movable. It is determined by contacting the upper part of the member 24.

  The cylindrical portion 24 c of the movable member 24 is provided with a pressing spring 26 as a first urging member in a concave portion 24 d inside thereof, and this pressing spring 26 exerts an urging force with the inner bottom surface 15 a of the holder 15. When exerted, the movable member 24 is urged in the direction in which the engaging claw 24 b engages with the ratchet teeth 23.

  Further, a second urging force is urged between the upper portion of the movable member 24 and the push button 21 (more specifically, a recess 21b formed therein) toward the upper limit position of the vertical movement stroke. A pressing spring 25 is provided as a member and a positioning means, and the push button 21 is always biased toward the upper limit position so that the push button 21 is positioned to the upper limit position and does not move upward (backlash). Is provided.

  The above is the configuration of the tilt device 20, and the operation of the tilt device 20 will be described below. FIG. 6A shows a state in which the tilt panel unit 10A is in a vertical posture (the state shown in FIG. 1), that is, a state in which the tilt panel unit 10A is not tilted.

  The ratchet teeth 23a and the engaging claws 24b are formed in a tooth profile that allows the rotation of the movable member 24 in the counterclockwise direction of FIG. 6, that is, the rotation in the direction of tilting the tilt panel unit 10A toward the front side of the apparatus. ing.

  Therefore, when the tilt panel unit 10A is tilted counterclockwise in FIG. 6, the engaging claw 24b easily gets over the ratchet teeth 23a as shown in the change from FIG. 6 (A) to FIG. 6 (B). However, it moves along the outer peripheral surface of the ratchet member 23. At this time, since the engaging claw 24b moves while entering the valley between the two ratchet teeth 23a, the movable member 24 moves in the radial direction of the ratchet member 23 in small increments.

  Even if the hand is released from the tilt panel unit 10A at an arbitrary tilt angle, the ratchet teeth 23a and the engaging claws 24b rotate the movable member 24 in the clockwise direction in FIG. 6, that is, the tilt panel unit 10A is in a vertical posture. Since the rotation in the direction returning to (FIG. 6A) is formed in a constraining tooth profile, the tilt angle is reliably maintained by the engagement of the ratchet teeth 23a and the engaging claws 24b.

  As described above, the ratchet mechanism including the ratchet teeth 23a and the engaging claws 24b constitutes a tilt angle holding unit that holds the tilt angle of the tilt panel unit 10A. The tilt angle holding means can adjust the tilt angle of the tilt panel unit 10A in small increments.

  On the other hand, when it is desired to return the tilt panel unit 10A to the vertical posture (FIG. 6A), the push button 21 is pressed from the upper limit position toward the lower limit position. Then, the movable member 21 is displaced, and the engaging claw 24b is disengaged from the ratchet teeth 23a (separated from the ratchet teeth 23a), whereby the tilt panel unit 10A can be returned to the vertical posture.

  Here, when the tilt panel unit 10A is tilted, as described above, the engaging claw 24b moves while entering the valley between the two ratchet teeth 23a (moves while jumping), so that the movable member 24 has a radius of the ratchet member 23. Move in small directions. For this reason, if the movable member 24 and the push button 21 are directly engaged, the push button 21 vibrates little by little with the tilting operation of the tilt panel unit 10A, which is not preferable in terms of the appearance of the apparatus. In addition, the sliding frictional resistance of the push button 21 gradually increases as the push button 21 moves up and down unnecessarily, and there is a possibility that the operational feeling of the push button 21 may be lowered at an early stage.

  However, in this embodiment, in the non-operating state where the push button 21 is not pressed, the push button 21 is positioned to the full upper limit position in the vertical movement stroke by the pressing spring 25, that is, moves upward in the non-operating state. Eliminating movement allowances are eliminated. For this reason, even if the movable member 24 moves little by little with the tilt operation, the push button 21 is prevented from vibrating (finely moving) little by little.

  Since the small movement of the movable member 24 is absorbed via the pressing spring 25, it is not preferable that the push button 21 and the movable member 24 are in direct contact with each other when the push button 21 is not operated. It is preferable that they are arranged in a space.

  Next, the tooth profile of the ratchet teeth 23a will be described in detail with reference to FIG. As shown in FIG. 7 (A), the ratchet teeth 23a and the engaging claws 24b can support the weight of the tilt panel unit 10A, and at a predetermined pressing force (such as in FIG. 6 (B)) when a button is operated. A shape that can hold the tilt angle even when applied with a symbol F) is formed. However, if the tilt angle is strictly held, the ratchet teeth 23a, the engaging claws 24b, or the tilt panel unit 10A may be damaged when an unexpected large pressing force F is applied.

  Therefore, in the present embodiment, the tooth surface (indicated by reference symbol P in FIGS. 7A and 7B) on the side of the ratchet tooth 23a that contacts the engaging claw 24b and maintains the tilt angle is the base end of the tooth surface P. In the opening angle (in FIG. 7B) with respect to the radial line (indicated by the symbol r in FIGS. 7A and 7B) of the ratchet member 23 passing through the side end portion (indicated by the symbol Q in FIG. 7B). (Indicated by the symbol α).

  Further details will be described below. 7A and 7B, a radius line r is a radius line passing through the axial center position c of the ratchet member 23 (the shaft 22a) (that is, the rotation center of the tilt panel unit 10A). ) Indicates a line obtained by extending the tooth surface P outward. As shown in the figure, the tooth surface P is formed by an inclined surface that forms an opening angle α (α> 0 °) with respect to a radial line r passing through the proximal end Q of the tooth surface P. In the present embodiment, the tooth surface in contact with the tooth surface P of the ratchet teeth 23a on the engagement claw 24b side is formed in parallel with the tooth surface P.

  Here, the symbol Fp indicates a reaction force that the engagement claw 24b receives from the ratchet teeth 23a when a predetermined pressing force F is applied to the tilt panel unit 10A. This reaction force Fp is perpendicular to the tooth surface P. Facing the direction. Reference numeral Fa indicates a component force of the reaction force Fp in a direction parallel to the slidable direction of the movable member 24, and reference numeral Fb indicates a biasing force by which the movable member 24 is biased by the pressing spring 26. Yes.

  Here, if the tooth surface P does not form a predetermined opening angle with respect to the radius line r as indicated by the symbol P ′, that is, if the ratchet teeth 23a are acute-angle teeth, the component force Fa is the biasing force Fb. As the pressing force F applied to the tilt panel unit 10A increases, the engaged state between the ratchet teeth 23a and the engaging claws 24b becomes stronger. Therefore, in this case, if the pressing force F becomes too large, the ratchet teeth 23a, the engaging claws 24b, or the tilt panel unit 10A side may be damaged.

  On the other hand, in the present embodiment, as described above, the tooth surface P is formed with an inclined surface that forms a predetermined opening angle α (α> 0 °) with respect to the radius line r, and therefore the component force Fa of the reaction force Fp. As shown in FIG. 7B, the direction is opposite to the biasing force Fb.

  Therefore, when a large pressing force F exceeding the predetermined pressing force F is applied to the tilt panel unit 10A from above while the predetermined tilt angle is held by the ratchet teeth 23a and the engaging claws 24b, the component force Fa is applied to the biasing force Fb. As a result, the engaging claw 24b slides to the right while contacting the tooth surface P, the engagement between the ratchet teeth 23a and the engaging claw 24b is released, and the engaging claw 24b is lowered one step downward. Is possible. Further, the urging force Fb is set to the magnitude of such urging force.

  Therefore, even if a large pressing force F exceeding the predetermined pressing force F is applied to the tilt panel unit 10A, it is possible to reliably avoid the damage of each component. Further, since the ratchet teeth 23a and the engaging claws 24b do not need to be enlarged so as not to cause damage to each component even when a predetermined pressing force F is applied, the enlargement of the entire apparatus is avoided. be able to.

  If the pressing force F when the engagement between the ratchet teeth 23a and the engaging claws 24b is released is a reference load, this reference load is, for example, the strength of each component such as the ratchet teeth 23a and the engaging claws 24b. Can be set in advance as a reference, or can be determined in advance based on a value obtained by adding a predetermined margin to the pressing force received from the user when the button of the tilt panel unit 10A is operated.

  In addition to the shapes of the ratchet teeth 23a and the engaging claws 24b described above, the tilt angle can be maintained until the pressing force F applied to the tilt panel unit 10A reaches a predetermined magnitude (engaged with the ratchet teeth 23a). The engagement state with the claw 24b can be maintained), and when the pressing force F of a certain level or more is applied to the tilt panel unit 10A, the engagement claw 24b generates a force in a direction away from the ratchet teeth 23a. If so, the ratchet teeth 23a or the engaging claws 24b may have any shape.

  Further, the shape of the ratchet teeth 23a and the engaging claws 24b is a shape for preventing breakage when a large pressing force exceeding a predetermined pressing force F is applied to the tilt panel unit 10A as described above. This is not an indispensable component for preventing small vibrations of the push button 21 accompanying the tilt operation described above. Therefore, in the case where the purpose is only to prevent small vibrations of the push button 21 due to the tilting operation, the ratchet teeth 23a have a tooth surface as indicated by a reference symbol P ′ in FIG. 7B, for example. It doesn't matter.

[Second Embodiment of the Invention]
Next, a second embodiment of the present invention will be described with reference to FIGS. 8 and 9 are external perspective views of the inkjet multifunction peripheral 1B according to the second embodiment of the present invention. FIGS. 10 and 11 are perspective views of the tilt device 30 according to the second embodiment of the present invention. 12 is an exploded perspective view, and FIGS. 13 and 14 are cross-sectional views. 8 and 9, the same components as those in the first embodiment (FIGS. 1 and 2) described above are denoted by the same reference numerals, and the description thereof will be omitted below.

  The inkjet multifunction peripheral 1B shown in FIGS. 8 and 9 includes a tilt panel unit 10B, and the tilt panel unit 10B rotates with respect to the apparatus main body 1a of the inkjet multifunction peripheral 1B via a tilt device 30 described later. (Tilt) is provided, and the tilt angle is maintained at an angle as shown in FIG. 9, for example.

  Reference numeral 31 denotes a push button. Unlike the above-described first embodiment, this push button 31 is provided not on the tilt panel unit 10B side but on the apparatus main body 1a side (that is, does not tilt with the panel). Structure).

Hereinafter, the tilt device 30 will be described in detail with reference to FIGS.
The tilt device 30 according to the present embodiment is provided in a fixed state on the printer device main body 1a side, a base holder member 38, a ratchet member 33 rotatably supported by the holder member 38, and a holder member 38. A movable member 34 that is rotatably supported, a push button member 31, opening springs 35, 36, a damper 37 provided on the holder member 38, a holder member 39 that holds the damper 37 on the holder member 38, It is configured with.

  The ratchet member 33 is a cylindrical member having a hole 33c for receiving the rotation shaft 32 of the tilt panel unit 10B. The rotation shaft 32 and the hole 33c have a substantially D shape in plan view as shown in FIGS. 13 and 14, whereby the ratchet member 33 is fixedly attached to the tilt panel unit 10B. The ratchet member 33 rotates in the holder member 38 in accordance with the tilting operation of the tilt panel unit 10B.

  The ratchet member 33 includes a plurality of ratchet teeth 33a along the outer periphery, and the ratchet teeth 33a engage with engagement claws 34a of the movable member 34 described later, whereby the tilt panel unit 10B has a predetermined tilt angle. Held in. That is, the ratchet teeth 33a and the engaging claws 34a constitute a tilt angle holding unit that holds the tilt panel unit 10B at a predetermined tilt angle.

  On the other hand, the movable member 34 provided with the engaging claw 34a is rotatably provided to the holder member 38 via the rotating shafts 34b and 34b, and by rotating, the movable claw 34a is engaged with the ratchet teeth 33a. Engage and disengage. The winding spring 35 as the first urging member exerts an urging force between the holder member 38 and the movable member 34, whereby the engaging claw 34a engages the ratchet teeth 33a. Energize to.

  As shown in FIG. 11, the push button member 31 includes an arm portion 31c extending upward from a fixing portion 31d fixed to the device frame 16 constituting the device main body 1a (of the inkjet multifunction device 1B), and an upper portion of the arm portion 31c. A support shaft 31b supported by a bearing portion 16a formed on the apparatus frame 16, an elastically deformable elastic deformation portion 31e extending from the support shaft 31b, and a push button connected to the elastic deformation portion 31e. The part 31a is formed of a resin material so as to be integrated with these parts.

  The push button portion 31a is disposed so as to form a predetermined gap between the push button portion 31a and the button engaging portion 34c of the movable member 34 in a non-operating state where the push button portion 31a is not depressed, as shown in FIG. When the push button portion 31a is pressed, as shown in the change from FIG. 13 to FIG. 14, the push button portion 31a is lowered downward by an amount corresponding to the push-in resistance due to the elastic deformation of the elastic deformation portion 31e. It contacts the joint 34c.

  When the push button portion 31a is further pressed, the push button portion 31a pushes the button engaging portion 34c from above, and the movable member 34 rotates to disengage the ratchet teeth 33a from the engaging claws 34a. It has come to be.

  The ratchet member 33 is formed with a gear portion 33b. The gear portion 33b is adapted to engage with the damper 37, and the ratchet member 33 is shown in FIGS. The counterclockwise direction, that is, the direction in which the tilt panel unit 10 returns to the vertical posture (the posture in FIG. 8) is urged.

  Therefore, when the push button portion 31a is pressed in a state where the tilt panel unit 10B is tilted and the engagement between the check teeth 33a and the engagement claws 34a is released, the tilt panel unit 10B receives the biasing force and tilt of the winding spring 36. The panel unit 10B is surely returned to the vertical posture by its own weight. At this time, the rotational speed when returning to the vertical posture is regulated by the damping effect of the damper 37.

  Since the support shaft 31b of the push button member 31 is supported by the bearing portion 16a formed on the apparatus frame 16, the push button portion 31a is moved by the elastic deformation portion 31e to the movable member 34 (button engaging portion 34c). A predetermined interval is formed between the two. That is, the elastic deformation portion 31e constitutes a positioning means for positioning the push button portion 31a so as to form a predetermined interval between the push button portion 31a and the movable member 34. Further, the elastic deformation portion 31e constitutes a positioning means for positioning the push button portion 31a to the full upper limit position in the up and down movement stroke.

  According to the tilt device 30 configured as described above, in a non-operating state in which the push button portion 31a is not pressed, between the button engagement portion 34c of the movable member 34 including the engagement claws 34a and the push button portion 31a. In other words, a space is formed in which the movable member 34 (button engaging portion 34 c) can move without interfering with the push button 31. Therefore, even if the engaging claw 34a jumps between the ratchet teeth 33a, the push button portion 31a can be prevented from vibrating in small increments.

  Further, since the elastic deformation portion 31e as positioning means for positioning the push button portion 31a in the non-operating state of the push button portion 31a is integrally formed with the push button portion 31a by resin molding, the cost of the apparatus is reduced. It is planned.
