Description

  The present invention relates to a button device incorporated in an image processing apparatus or the like.

  Various button devices for accepting operation inputs are incorporated in an operation panel of a digital multi-function peripheral having a facsimile function, a print function, a scanner function, and the like.

  As a prior art disclosing a button device incorporated in a digital multifunction peripheral, for example, there is one disclosed in Patent Document 1.

JP 2005-86461 A

  As the button device as described above, one having the following configuration is proposed.

  In the button device according to the proposed example, a substantially circular button portion is supported by an operation panel via an elastic support frame so as to be freely pressed, and a light emitting portion and a switch portion are disposed below the button portion. It becomes the composition.

  The light emitting part is disposed substantially below the center of the button part in order to make the button part shine neatly. For this reason, the switch portion is disposed at an eccentric position of the button portion, and the button portion presses the switch portion via a switch pressing portion projecting from the lower surface thereof.

  However, in the button device as described above, if the button portion is pressed strongly, the elastic support frame may be damaged. When the elastic support frame is damaged, the button part is freely rotatable, and in the button having a rotatable shape, the switch pressing part is detached from the position of the switch part. Then, even if the button part is pressed down, a situation may occur in which the switch part cannot be pressed.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a button device that can more reliably press a switch portion.

  In order to solve the above problems, the present invention provides a button device that accepts an input operation, and includes a panel having a button mounting opening formed in a non-circular opening shape in plan view, and the button mounting opening. A button main body formed in a non-circular outer peripheral shape corresponding to the shape and size of the opening, a fixing portion supported on the panel side, and an elasticity interposed between the fixing portion and the button main body. A button support frame portion having an arm portion, a switch pressing portion projecting from the eccentric position of the button main body portion toward the inward of the panel, and a button portion inside the panel. And a switch portion provided at a position corresponding to the switch pressing portion.

  In this case, you may further provide the light emission part provided in the inner side of the approximate center part of the said button main-body part.

  In addition, an elastic abutting portion capable of abutting against a member provided on the inner side of the panel is provided at a point-symmetrical position with respect to the switch pressing portion with respect to a substantially central portion of the button main body portion. May be.

  Furthermore, the button unit may be assigned so as to accept a predetermined input by being pressed for a long time.

  According to the button device of the present invention, in a normal state, the button main body is elastically held in the button mounting opening in a state where the rotation of the button main body is suppressed by the support frame. Even if the elastic arm portion is damaged, the button mounting opening of the panel is formed in a non-circular shape in plan view, and the button main body also has a plane corresponding to the opening shape and size of the button mounting opening. Since the non-circular shape is formed, the rotation of the button body is suppressed. Therefore, the position of the switch pressing part is not easily displaced from the switch part, and the switch part can be pressed more reliably.

  In addition, in the configuration further including the light emitting portion provided in the substantially central portion of the button main body portion, the switch pressing portion and the switch portion cannot be provided in the substantially central portion of the button portion. It is necessary to dispose the button body at an eccentric position. Therefore, with respect to such a button device, the switch portion can be pressed more reliably.

  In addition, an elastic abutting portion capable of abutting against a member provided on the inner side of the panel is provided at a point-symmetrical position with respect to the switch pressing portion with respect to a substantially central portion of the button main body portion. Then, when the button main body is pushed in, the elastic contact portion comes into contact with the member even on the opposite side of the positions of the switch pressing portion and the switch portion. Therefore, the button main body portion is not easily tilted, and the button main body portion can be pushed in and returned smoothly.

  Further, if the button portion is assigned to receive a predetermined input by being pressed long, a relatively strong force is likely to be applied. If such a relatively strong force is repeatedly applied, the button support frame part may be damaged. In such a configuration, even if the button support frame portion is broken, it is particularly effective to employ a configuration in which the switch pressing portion is not easily displaced from the switch portion and the switch portion can be pressed more reliably.

  Hereinafter, a button device according to an embodiment of the present invention will be described. In the present embodiment, an example in which a button device is applied to an image processing device, more specifically, an example in which the button device is applied to a switch panel for a one-touch key of a digital multifunction peripheral will be described.

  More specifically, a platen glass 36 that is a substantially rectangular plate-like transparent member is disposed on the upper surface of the housing portion 33. The platen glass 36 is formed to have a size that is wide enough to spread and place a document to be placed. Further, a contact glass 35 that is a substantially rectangular plate-like transparent member is disposed on the upper surface of the housing portion 33 and on one side of the platen glass 36. The contact glass 35 has a length dimension corresponding to the width of the conveyed document.

  In addition, a reading device 38 and a light receiving unit 39 are mainly provided in the housing unit 33.

  The reading device 38 is configured to irradiate the placed document or the conveyed document with light and guide the reflected light toward the light receiving unit 39. Here, the reading device 38 has a light source that illuminates the document, a mirror that reflects light from the document (both not shown), and the like, and a moving means (not shown) below the contact glass 35 and the platen glass 36. It is arrange | positioned so that a reciprocating movement can be received under the driving force of.

  The light receiving unit 39 is configured to be able to form an image of reflected light 39L from a document on a built-in CCD (configured as a line sensor) via a lens via the reading device 38 and the like. Thereby, the reflected light from the document is converted into an electric signal by photoelectric conversion. A plurality of carriages are provided in order to keep the optical path length from the document reading surface to the light receiving unit 39 constant.

  The document pressing cover unit 40 includes a document pressing unit 40 a and an automatic document conveying device 45. The document pressing cover portion 40 is attached to one side of the image reading main body portion 32 through a hinge portion 31 so as to be freely opened and closed.

  When reading a document by the sheet feed method, the automatic document feeder 45 conveys the document so that the document is brought into contact with the contact glass 35 while the reading device 38 is stationary below the contact glass. The document is read.

  When the original is read by the flat bed method, the original is placed on the platen glass 36, and the original pressing cover 40 is closed so that the original pressing unit 40a presses the original. The original is read by scanning the reading device 38 below the platen glass 36.

  An operation panel 50 is provided on one side (front) of the reading unit 30. The operation panel 50 is provided with various switches 52, a button device 60, and a touch panel 54. The various switches 52 and the button device 60 accept various operations on the digital multi-function peripheral 10. The touch panel 54 accepts such various operations and also functions as a display unit that displays the operation status, operation contents, and the like of the digital multi-function peripheral 10.

<2. Details of button device>
Details of the button device 60 incorporated in the operation panel 50 of the digital multi-function peripheral 10 will be described. Here, a description will be given by focusing on one button device 60, more specifically, the button device 60 that accepts an input operation for power saving mode switching. The configuration here is of course applicable to other button devices 60.

  FIG. 2 is a plan view showing the button device, and FIG. 3 is a block diagram showing a configuration for receiving an input to the button device.

  The button device 60 is incorporated in a part of the operation panel 50. The button device 60 is assigned a function of accepting an input operation for power saving mode switching.

  That is, the button device 60 is connected to the push time determination unit 64 via the input circuit unit 62. When the button device 60 is pushed, an ON signal corresponding to the pushing operation time is given to the pushing time determination unit 64 via the input circuit unit 62. The push time determination unit 64 is configured by a general microcomputer having a CPU, a ROM, a RAM, and the like, and performs the following processing using a software program stored in advance. That is, the push time determination unit 64 compares the push operation time with a preset reference time, and outputs a sleep mode switching command when it is determined that the push operation time is shorter than the reference time. On the other hand, when the push time determination unit 64 determines that the push operation time is longer than the reference time, it outputs a power-off mode switching command. That is, when the button device 60 is operated so as to be pushed in a relatively short time, a sleep mode switching command is output, and when the button device 60 is long pressed, a power-off mode switching command is output. These sleep mode switching command or power-off mode switching command is given to a control unit that controls the entire digital multi-function peripheral 10. Then, the control unit switches the entire operation state of the digital multi-function peripheral 10 to the sleep mode or the power-off mode according to the given command. The sleep mode is a mode in which the operation of some electric elements is stopped from the normal operation of the digital multifunction peripheral 10 to reduce the power consumption, and the power off mode is an operation of more electric elements from the sleep mode. Is a mode in which power consumption is further reduced by stopping the operation.

  In this way, the button device 60 is assigned a function for receiving a predetermined input according to the time of the input operation.

It is XI-XI sectional view taken on the line.

  As shown in FIGS. 2 and 4 to 11, the button device 60 includes an operation panel 50, a button unit 70, and a switch unit 82.

  The operation panel 50 is formed with a button mounting opening 50h. Here, a button attachment opening 50 h is formed in a portion of the operation panel 50 from one corner. The button mounting opening 50h is formed in a non-circular shape in plan view, here, a substantially elliptical shape in plan view (see FIGS. 2, 5, and 11). Further, a button housing cylinder part 56 having a substantially elliptical cylindrical shape is formed from the peripheral part of the button mounting opening part 50h toward the lower side of the operation panel 50 (see FIGS. 5 and 11). A button main body 72, which will be described later, is housed in the button housing cylinder 56 so as to be movable up and down. Further, a button support protrusion 58 is formed so as to protrude from the inner surface (lower surface) of the operation panel 50 and from the peripheral edge of the button mounting opening 50h (see FIGS. 5 and 11). Here, the button support protrusions 58 are formed in a columnar shape, and two are formed here. The button support protrusion 58 fixes and holds a fixing portion 75 of a support frame portion 74 described later with respect to the operation panel 50 at a fixed position.

  Further, a substrate 80 is disposed in the operation panel 50 (see FIGS. 4 and 11). The substrate 80 is attached and fixed to a frame (not shown) at a position spaced a predetermined distance below the operation panel 50. A switch unit 82 and a light emitting unit 84 are mounted and fixed on the substrate 80 (see FIGS. 4 and 11).

  The switch unit 82 is a push switch, and what is called a tact switch or a light touch switch is used. The switch unit 82 is provided at a position corresponding to a switch pressing unit 78 (described later) of the button unit 70 inside the operation panel 50. Here, the switch part 82 is positioned at the outer peripheral side of the button main body part 72 (more specifically, the position on the outer peripheral side of the ellipse and the position between the major axis extension line and the minor axis extension line). Is provided. The switch portion 82 is mounted and fixed to the substrate 80 with the operation portion 82a that receives the pushing operation force facing upward, and is turned on by receiving the force from above.

  Note that a position of point symmetry with respect to the switch portion 82 of the substrate 80 about the substantially central portion (substantially center) of the button main body portion 72 is a contact portion 81 on which an elastic contact portion 79 described later can contact. It is said that. Here, the contact portion 81 is formed on a flat surface on which various components are not mounted.

  The light emitting unit 84 is a component that emits light by itself, and is, for example, a light emitting diode 84a (see FIGS. 4 and 11). The light emitting portion 84 is provided inward (downward) of a substantially central portion (substantially center) of the button main body portion 72. Here, the light emitting unit 84 includes two light emitting diodes 84a. The light emitting portion 84 having the two light emitting diodes 84a is provided inside the substantially central portion of the button main body 72 as a whole. That is, the fact that the light emitting portion 84 is provided at the inner side of the substantially central portion of the button main body portion 72 does not necessarily mean that each light emitting element is provided at the substantially central portion of the button main body portion 72. In other words, it means that the light emitting portion 84 is provided inside the substantially central portion of the button main body portion 72 as a whole.

  Here, the two light emitting diodes 84a are provided to enable two-color light emission.

  As described above, in the configuration in which the light emitting portion 84 is provided in the substantially central portion of the button main body portion 72, the switch portion 82 and the switch pressing portion 78 are disposed at an eccentric position of the button main body portion 72 in terms of layout. Need to do.

  The button portion 70 includes a button main body portion 72, a support frame portion 74, a switch pressing portion 78, and an elastic contact portion 79, and is a member integrally formed of a resin such as a transparent resin or a translucent resin. is there.

  The button main body 72 is formed in a non-circular shape in plan view corresponding to (substantially the same) the opening shape and size of the button mounting opening 50h. More specifically, the button main body 72 has one end side (upper end side) of a cylindrical portion 72a formed in a substantially elliptic cylindrical shape closed by the operation receiving portion 72b and the other end side (lower end side) opened. The shape is made. And the planar view shape which looked at the cylinder part 72a from the operation receiving part 72b side is formed in the shape (substantially same) corresponding to the opening shape and magnitude | size of the button attachment opening part 50h. Thereby, the cylinder part 72a is accommodated in the button attachment opening 50h so as to be movable along the axial direction so as to fit into the button attachment opening 50h. Moreover, the collar part 72c projected outside is formed in the peripheral part of the other end side (lower end side) of the cylinder part 72a. Then, in a state where the cylinder portion 72a is accommodated in the button attachment opening 50h, the flange portion 72c abuts on the inner end portion (lower end portion) of the button accommodation cylinder portion 56, so that the button main body portion 72 is attached to the button. This prevents the upper opening 50h from being removed upward.

  The support frame portion 74 includes a fixed portion 75 and an elastic arm portion 76 that are supported on the operation panel 50 side.

  The fixing portion 75 is a substantially U-shaped member in which side support pieces 75b are formed to protrude from both ends of the main support piece 75a, and is provided so as to surround the three sides around the button main body 72. A fixing piece 75c having a fixing hole 75h is formed at each intersection of the main support piece 75a and each side support piece 75b. The support frame portion 74 is fixed at a fixed position with respect to the operation panel 50 by inserting the tip end portions of the button support protrusions 58 into the fixing holes 75h and fixing them. As a specific configuration for fixing each button support protrusion 58 to the fixing piece 75c, for example, an engagement structure formed at the tip of each button support protrusion 58 is engaged with the fixing hole 75h and fixed. And a configuration in which the distal end portion of each button support protrusion 58 is inserted into the fixing hole 75h and then the distal end portion is thermally crushed. Further, a configuration in which a screw hole is formed at the tip of each button support protrusion 58, and a screw inserted through the fixing hole 75h is screwed into the screw hole to be fixed, etc. However, the configuration for fixing the fixing portion 75 to the operation panel 50 is not limited to the above example. For example, various engagement structures, adhesion, welding methods, pinching methods, and the like, and between the operation panel 50 and the substrate 80 are used. Various configurations, such as a configuration of being sandwiched and fixed, can be employed.

  The elastic arm portion 76 is a member interposed between the fixing portion 75 and the button main body portion 72, and elastically holds the button main body portion 72 in a state of being accommodated in the button mounting opening 50h. More specifically, the elastic arm portion 76 includes an extending arm portion 76 a extending from the side support piece 75 b toward the button main body portion 72 side, and a curved arm portion 76 b extending along the outer periphery of the button main body portion 72. have. The extending arm portion 76 a is a linear piece extending from the side support piece 75 b toward the substantially central portion of the button main body 72. Further, the curved arm portion 76b extends along a quarter portion of the substantially oval outer periphery of the button body portion 72. More specifically, the curved arm portion 76b of the approximately oval outer periphery of the button body portion 72 It is formed in a shape that extends from a portion that intersects the major axis to a portion that intersects the minor axis next to it. In addition, of the curved arm portion 76 b, the portion on the long axis side of the substantially oval outer periphery of the button body portion 72 is connected to the extending arm portion 76 a, and the portion on the short axis side is connected to the button body portion 72. Yes. As described above, by adopting a configuration in which the elastic arm portion 76 is detoured around the button main body portion 72, the elastically deformable portion of the elastic arm portion 76 can be elongated to prevent a local load from being applied.

  Further, in this embodiment, the elastic arm portion 76 as described above is provided at a point-symmetrical position rotated 180 degrees around the substantially central portion of the button main body portion 72, and the button main body portion 72 is elastically supported at two locations. is doing.

  By such an elastic arm portion 76, the button main body portion 72 is elastically supported so as to urge it upward so that the collar portion 72 c is brought into contact with the inner end portion (lower end portion) of the button accommodating cylinder portion 56. .

  Further, the switch pressing portion 78 is provided so as to face inward of the operation panel 50 from a position eccentric from the substantially central portion of the button main body portion 72. Specifically, a part of the outer peripheral portion of the collar portion 72c of the button main body 72 (more specifically, the outer peripheral portion of the collar portion 72c that is sandwiched between the major axis extension line and the minor axis extension line thereof. ) Is formed so as to protrude outward, and a switch pressing portion 78 is formed so as to protrude from the lower surface of the extended piece 78P. The position where the switch pressing portion 78 is formed in this way is a position facing the switch portion 82 in a state where the button main body portion 72 is incorporated in the operation panel 50. The length of the switch pressing portion 78 is such that the tip of the switch pressing portion 78 faces the operation portion 82a of the switch portion 82 in the state where the button main body 72 is incorporated in the operation panel 50. It is set to such an extent that it is opposed to the portion 82a with a slight gap (see FIG. 11).

  Further, the elastic contact portion 79 is located on the substrate 80 at a point-symmetrical position (here, a position rotated by 180 degrees) with respect to the switch pressing portion 78 about the substantially central portion of the button main body portion 72. It is provided so that it can contact. Specifically, the elastic contact portion 79 is a part of the outer peripheral portion of the collar portion 72 c of the button main body portion 72 (more specifically, the outer peripheral portion of the collar portion 72 c and substantially the center of the button main body portion 72. An extension piece 79a is formed so as to protrude outward from the opposite side of the center), and a protrusion 79b is formed so as to protrude from the lower surface of the extension piece 79a. The length of the protrusion 79b is such that the tip of the protrusion 79b can contact the contact portion 81 of the substrate 80 or can be opposed to the contact portion 81 with a slight gap. Is set.

  Note that the elastic contact portion 79 is not necessarily in contact with the substrate 80 and may be in contact with a predetermined member inside the operation panel 50.

  Such a button device 60 is manufactured as follows.

  First, the button main body 72 is inserted into the button mounting opening 50 h from the inner surface (lower surface) of the operation panel 50, and the distal ends of the button support protrusions 58 on the inner surface (lower surface) of the operation panel 50 are connected to the button portion 70. The button part 70 is attached to the inner surface side of the operation panel 50 through the fixing hole 75h. Thereafter, the operation panel 50 is covered with the substrate 80, and the operation panel 50 is fixed to a predetermined support member with screws or the like. Then, the light emitting portion 84 is disposed at a substantially central portion in the button main body portion 72, the distal end portion of the switch pressing portion 78 is opposed to the operation portion 82a of the switch portion 82, and the elastic contact portion 79 is the substrate. It will be in the state arrange | positioned facing 80 contact parts 81 (refer FIG. 11).

  The operation on the button device 60 is performed as follows. That is, in the initial state, when the button main body 72 is pushed from the outer surface (upper surface) of the operation panel 50 with a human finger or the like, the button main body 72 is pushed down while the elastic arm 76 is elastically deformed, and the switch pressing portion. The tip of 78 pushes in the operation part 82a of the switch part 82.

  At the same time, since the elastic contact portion 79 contacts the contact portion 81 of the substrate 80 while being elastically deformed, with respect to the position where the tip of the switch pressing portion 78 pushes the operation portion 82a of the switch portion 82, A force that urges the button main body 72 in a direction away from the substrate 80 also acts at a position opposite to the substantially central portion of the button main body 72. That is, a force that urges the button main body portion 72 in a direction away from the substrate 80 is applied to the button main body portion 72 at approximately two positions across the substantially central portion. For this reason, when the button main body 72 is pushed in, the button main body 72 is not easily tilted, and the button main body 72 can be pushed in and returned smoothly.

  And if the force which pushes in the button main-body part 72 by a human finger etc. is cancelled | released, it will reset to the said initial state with the original shape return force of the operation part 82a, and the elastic return force of the elastic arm part 76. FIG.

  By the way, regarding the button device 60, a strong force may be applied to the elastic arm portion 76, or the elastic arm portion 76 may be damaged due to fatigue, deterioration over time, or the like. In particular, when the button device 60 receives an operation by a long press, the button main body 72 may be unintentionally pressed strongly when trying to press the button device. In such a case, the elastic arm portion 76 is damaged. May lead to

  If both of the two elastic arm portions 76 are damaged, the elastic support of the button main body 72 by the elastic arm portion 76 cannot be expected. However, in the button device 60, the button attachment opening 50h of the operation panel 50 is formed in a non-circular shape in plan view, here, in a substantially elliptical shape in plan view, and the button main body 72 is provided for the button attachment. It is formed in a non-circular shape in a plan view corresponding to (substantially the same) the opening shape and size of the opening 50h. For this reason, even if both elastic arm portions 76 are damaged, the rotation of the button main body 72 at the button mounting opening 50h is suppressed. Therefore, the position of the switch pressing portion 78 is not easily displaced from the switch portion 82, and the switch portion 82 can be pressed more reliably.

  In addition, since the button main body 72 does not rotate, it is possible to prevent the characters or the like written on the surface of the button main body 72 from becoming difficult to see.

  In addition, if the force which pushes in the button main-body part 72 is cancelled | released after pushing in the switch part 82, the button main-body part 72 will be at least the upper position which does not push in the switch part 82 with the original form return force of the operation part 82a Return to. For this reason, there is no problem in operation.

<3. Modification>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made.

  For example, the planar view shapes of the button attachment opening 50h and the button main body 72 have been described as being substantially elliptical as an example of a non-circular shape in plan view, but are not limited thereto. For example, the shape in plan view may be a polygonal shape such as a substantially triangular shape or a substantially rectangular shape, or a noncircular shape as a whole by forming a concave portion or a convex portion in a part of the outer peripheral portion of the substantially circular shape. It doesn't matter if you make it.

  Further, the button device 60 is not limited to accepting the power saving mode switching input operation as described above, and can be applied to various button devices 60 that accept various inputs.

  Further, in the present embodiment, an example in which the present invention is applied to a digital multi-function peripheral having various functions such as a FAX function, a copy function, a scan function, and a print function has been described, but the present invention is not necessarily limited thereto.
