Description

  The present invention relates to a switch structure.

  For example, as a conventional switch structure provided in an electronic device such as a digital camera (imaging device) with a waterproof function, an operation button provided outside the housing of the device and a switch provided inside operated by the operation button In order to prevent water from entering the device, a waterproof material is disposed between the switch and the periphery thereof (see, for example, Patent Document 1).

  Such a waterproof switch structure needs to securely fix a waterproof material at a predetermined position. Therefore, a switch structure is also known in which a sheet metal member that can be screwed is placed on a waterproof material and fixed by screwing the waterproof material into a predetermined position inside the housing, thereby securely closing the gap between the fixing points. It has been.

  The sheet metal member used for the switch structure is a structural member (boss) that transmits the movement of the operation button provided on the casing of the device to the switch so that the switch protected by the waterproof material is operated. The hole which penetrates is formed.

  As an example of a structure for transmitting the movement of the operation button to the switch, there is a structure in which a boss protruding downward in the stroke direction is formed integrally with the operation button on the bottom surface of the operation button. The boss moves in accordance with the vertical movement of the operation button (movement that pushes down the operation button in the stroke direction), and the switch can be pressed by this movement. Therefore, it is necessary to form a hole through which the boss passes in the sheet metal member.

  In such a switch structure, when the operation button is pressed, the boss is pressed accordingly, and the waterproof material is pushed down through the sheet metal member. The switch operation is performed by pressing the key top of the switch with the pressed waterproof material.

  In the conventional switch structure described above, the length in the stroke direction of the boss of the operation button becomes longer depending on the thickness of the sheet metal member and the waterproof material. However, the conventional switch structure does not consider a structure that prevents the boss from wobbling in the horizontal direction in order to reliably transmit the vertical movement of the boss to the switch.

  Also, if the length of the boss in the stroke direction is increased, the operation button will be pushed down diagonally when the load applied when operating the operation button is biased to a position off the center of the operation button. Since the force with which the boss is pushed down is also inclined, the force applied to the key top of the switch also shifts, and the switch may not respond to the pressing operation of the operation button.

  Further, the operation button has a flange formed at the edge portion to prevent the operation button from falling off. This flange has a larger diameter than the hole formed in the exterior cover of the housing, but if the load applied when operating the operation button is deviated from the center of the operation button, the operation button itself may shift obliquely. As a result, the flange bites into the hole and does not return to the predetermined position.

  Thus, in the conventionally known switch structure, there is no known one that aims to solve the problem caused by the length in the stroke direction of the boss of the operation button.

  The present invention has been made in view of the above problems, and in a switch structure in which the length of the operation button in the stroke direction is long, the switch structure that prevents the operation button from wobbling and is excellent in operability, and the switch structure It is an object of the present invention to provide an electronic apparatus and an imaging apparatus including

  Hereinafter, embodiments of a switch structure according to the present invention, and an electronic apparatus and an imaging apparatus including the switch structure will be described. In the following description, a digital camera (imaging device) provided with a waterproof switch structure according to the present invention is used as an example. That is, a digital camera is an example of an electronic device according to the present invention.

  The appearance of the digital camera will be described with reference to FIG. The digital camera 1 can be used underwater as well as on land. As shown to Fig.1 (a), the housing | casing 2 which prevents the penetration | invasion of the water to the inside of the digital camera 1 is provided.

  A photographing optical system 3 configured as a zoom optical system with a variable focal length is disposed in the front center portion of the digital camera 1. Further, a strobe light emitting unit 4 for irradiating illumination light is disposed at the upper right part of the front of the digital camera 1.

  On the top surface of the digital camera 1, there are arranged an operation button 5 that is a release switch for inputting a photographing operation and a power button 6 for turning on / off the power of the digital camera 1. The operation button 5 is arranged at a position where the photographer can push with the index finger of the right hand.

  A zoom button 9 for changing the focal length of the photographing optical system 3 between the telephoto side and the wide side is displayed at the upper right corner of the back of the digital camera 1, and a photographed still image / video is displayed on the left side, or digital A display screen 10 for displaying various information related to the camera 1 and a display screen between them are switched to the playback mode, the shooting condition of the digital camera 1 is changed, the shot image is deleted, A plurality of mode buttons 11 for changing the display content of 10 are arranged. The display screen 10 is a display element 10a composed of a liquid crystal display or the like, for example, and the display element 10a is covered with an acrylic member 10b so as to be watertight.

  Further, an electronic board (not shown) is mounted inside the housing 2 and is electrically connected to various buttons and dials provided on the outer surface of the digital camera 1 so as to function as the digital camera 1. Yes. An electronic board (not shown) is provided with a switch that operates when the operation button 5 is pushed. When this switch is turned on, the digital camera 1 performs a predetermined imaging process.

  Next, the switch structure according to the present embodiment will be described using an example of the detailed structure of the digital camera 1 shown in FIGS. FIG. 2 is an exploded perspective view showing the digital camera 1 as viewed from the rear right side. 3 is an enlarged exploded perspective view in which a portion of the rectangular area A shown in FIG. 2 is enlarged.

  In FIG. 2, the switch structure of the digital camera 1 includes a switch disposed inside a storage portion 21 formed on the top surface of the housing 2, and an elastic member 22 having a waterproof property on the storage portion 21. The metal sheet metal member 23 that fixes the elastic member 22 with the screw 24, the mold member 7 that is fixed to the sheet metal member 23, and the operation button 5 that is inserted through the mold member 7 are provided.

  The digital camera 1 also has an exterior cover 8 that protects the upper surface of the housing 2 that covers the switch structure. The operation button 5 is prevented from falling off by the exterior cover 8. That is, the outer cover 8 is formed with a hole 81 having a diameter larger than the diameter of the top plate exposed to the outside of the operation button 5 and smaller than the diameter of the flange provided on the outer periphery of the operation button 5. The top plate of the operation button 5 is exposed from the hole 81 and fixed in an operable manner, and the operation button 5 is prevented from coming out of the hole 81.

  This will be further described with reference to FIG. As shown in FIG. 3, a switch 50 is disposed inside the storage unit 21. Further, a rib 21a is formed in the storage portion 21 over the entire circumference. The elastic member 22 is made of, for example, silicon rubber, and has an outer peripheral dimension that is slightly larger than the outer periphery of the rib 21a. By covering and fixing the elastic member 22 on the storage portion 21, the switch 50 can be waterproofed.

  When the elastic member 22 is placed on the rib 21 a of the storage portion 21, the sheet metal member 23 is placed thereon, and the sheet metal member 23 is fixed to the housing 2 by the screw 24, the pressure applied to the elastic member 22 from the sheet metal member 23 Thus, the elastic member 22 is pushed around the rib 22a. As a result, the elastic member 22 and the rib 21a are in a watertight state, and water can be prevented from entering the switch 50.

  Here, the storage unit 21 will be described. As shown in FIG. 4, ribs 21 a are provided on the entire circumference of the storage portion 21. As described above, the elastic member 22 is placed on the rib 21a, and the sheet metal member 23 is placed thereon. When the sheet metal member 23 is placed on the elastic member 22, a gap is generated between the housing 2 and the sheet metal member 23. When the sheet metal member 23 is fixed to the housing 2, the elastic member 22 is The amount to be compressed is equivalent.

  Returning to FIG. The switch 50 having a waterproof structure by the elastic member 22 and the sheet metal member 23 fixed as described above is depressed by the elastic member 22 when the operation button 5 is depressed, and the key of the switch 50 is depressed by the depressed elastic member. The top is pushed down and operated. On the bottom surface of the operation button 5, a boss 5a for operating the key top by pressing down the elastic member 22 is formed. The boss 5a is formed so as to protrude in the pushing direction (stroke direction) of the operation button 5, and is fitted into a hole 22a of the elastic member 22.

  A hole 23 a is formed in the sheet metal member 23 so that the boss 5 a reaches the elastic member 22. The sheet metal member 23 is made of metal and has a predetermined thickness. Since the operation button 5 is made of resin such as plastic, the boss 5a is also made of resin.

  Here, if the hole 23a and the boss 5a are in direct contact with each other when the boss 5a slides in the vertical direction (stroke direction), the boss 5a is consumed due to friction with the hole 23a. The tip of the boss 5a is fitted in the hole 22a of the elastic member 22, but the operation stroke of the operation button 5 is increased and the length of the boss 5a in the stroke direction is increased depending on the thickness of the elastic member 22 and the sheet metal member 23. . When the stroke becomes longer, the operation button 5 is likely to wobble in the horizontal direction, and when a biased load is applied to the operation button 5, the top plate portion or the flange portion of the operation button 5 is inserted into the hole 81 of the outer cover 8. It will get caught and the operability will deteriorate.

  In order to prevent such deterioration in operability, the switch structure according to the present embodiment supports the boss 5a of the operation button 5, and the operation button 5 and the boss 5a are stroked even when a biased load is applied to the operation button 5. It has the mold member 7 for guiding so that it may slide to a direction.

  The mold member 7 is a resin molded product that is engaged with and fixed to the hole 23 a of the sheet metal member 23. The mold member 7 is fitted by insertion in the vertical direction (stroke direction) and rotation in the horizontal direction.

  The basic shape of the mold member 7 is a cylindrical shape, and a flange portion is integrally formed on the top surface portion of the cylindrical shape. The cylindrical portion of the mold member 7 is fitted into the hole 23a of the sheet metal member 23 and is fixed to the sheet metal member 23 by the flange portion. A detailed description of the mold member 7 will be described later.

  Next, the switch structure will be described in detail. FIG. 5 is an example of a longitudinal sectional view of the switch structure according to the present embodiment. FIG. 5A shows a state in which the elastic member 22 is placed on the rib 21 a of the storage portion 21. FIG. 5B shows a state in which the sheet metal member 23 is fixed by screws 24.

  In FIG. 5A, the elastic member 22 is formed so that the cross-sectional shape matches the storage portion 21, and a hole 22 a into which the tip portion of the mold member 7 is fitted is formed immediately above the switch 50. ing. The elastic member 22 rides on the rib 21a, and a sheet metal member 23 to which the mold member 7 is fixed is placed thereon. Since the sheet metal member 23 is in a state before being fixed by a screw 24 (not shown), a gap d is formed between the sheet metal member 23 and the housing 2.

  When the sheet metal member 23 is fixed to the housing 2 using a screw 24 (not shown), the state shown in FIG. That is, when the screw 24 is tightened, the sheet metal member 23 is gradually pushed down until the sheet metal member 23 comes into contact with the peripheral edge portion of the storage portion 21, and the gap d is eliminated. Then, as shown in FIG. 5 (b), the elastic member 21 comes into close contact with the rib 21a and enters a watertight state, so that the switch 2 can be prevented from entering the switch 50 from the outside.

  As the sheet metal member 23 is lowered, the mold member 7 also pushes down the elastic member 22 to be more deeply fitted into the hole 22a. At this time, the mold member 7 receives pressure from the elastic member 22, but since the mold member 7 is made of a harder material than the elastic member 22, the elastic member 22 side (hole 22a) is deformed. The side does not deform.

  FIG. 6 is a longitudinal sectional view according to a state in which the operation button 5 is fixed to the mold member 7. As shown in FIG. 6, the boss 5 a of the operation button 5 is inserted and fixed in a hole formed in the cylindrical portion of the mold member 7. Further, the operation button 5 has a flange formed to prevent the operation button 5 from being caught around a hole 81 formed in the exterior cover 8.

  When the operation button 5 is pushed down, the boss 5a descends inside the cylinder of the mold member 7 and pushes down the elastic member 22. The pushed-down elastic member 22 pushes down the key top 50a of the switch 50. As a result, the switch 50 is operated. Here, in order to return the depressed operation button 5, it is necessary to urge the operation button 5 in the direction in which the operation button 5 is lifted. Therefore, the spring 5 b is disposed around the boss 5 a on the bottom surface of the operation button 5. . Since the spring 5b is disposed between the bottom surface of the operation button 5 and the top surface portion of the mold member 7, if the pressing force disappears after the operation button 5 is pressed down, the operating force is restored by the restoring force of the spring 5b. The button 5 can be returned to the original position.

  Since the mold member 7 is an integrally molded product made of a resin, even if a load is applied to a position off the center of the top surface of the operation button 5, that is, the mold member 7 is detached from a position that directly hits the boss 5a. Even if the location is pressed, the boss 5a moves vertically to the key top 50a while sliding inside the cylindrical hole (hole) of the mold member 7. Further, when the operation button 5 is returned by the spring 5b, the operation button 5 is not caught by the housing 2, and is returned by the elasticity of the spring 5b.

  The diameter of the boss 5a is smaller than the diameter of the hole of the cylindrical portion of the mold member 7, but has a dimension that allows the boss 5a to be inserted almost without a gap. That is, in the state where the boss 5a is fitted in the mold member 7, the operation button 5 does not wobble in the horizontal direction.

  In addition, the diameter of the front-end | tip part of the boss | hub 5a is a little smaller than the diameter which concerns on the middle from the root. As a result, the force for pushing down the key top 50a is not distributed by the elastic member 22, and the key top 50a can be pushed down more reliably, and the operability of the switch 50 can be improved.

  As described above, according to the switch structure according to the present embodiment, horizontal wobbling is prevented by the mold member 7 and the operability of the operation button 5 is improved.

Next, the shape of the mold member 7 used in the switch structure according to the present embodiment and the method for fixing the mold member 7 to the sheet metal member 23 will be described in detail.
7A is a top perspective view of the mold member 7, FIG. 7B is a bottom perspective view of the mold member 7, and FIG. 7C is a side view of the mold member.

  As shown in FIG. 7A, the mold member 7 is an integrally molded product having a cylindrical portion 71 having a basic shape and a flange portion 72 on the top surface side of the cylindrical portion 71. The length of the cylindrical portion 71 in the axial direction is as long as possible in the layout, and the cylindrical portion 71 has a gap that minimizes the cross stacking with respect to the boss 5a of the operation button 5. In consideration, a hole 71a is formed.

  The flange portion 72 has a shape in which the top surface portion of the cylindrical portion 71 is expanded in the radial direction with a predetermined dimension. A notch is formed in a part of the flange portion 72. A leg portion 72 a that protrudes from the cylindrical portion 71 in the outer peripheral direction is formed in a part of the notch. A rib 72c having a predetermined height is formed at the tip of the leg 72a.

  A rib 73 is formed on the outer peripheral surface of the cylindrical portion 71 where the flange portion 72 is notched. Details of the rib 73 will be described later.

  As shown in FIG. 7B, a plurality of ribs 72 b are formed on the bottom surface side of the flange portion 72. The rib 72 b is formed with a dimension that slightly protrudes from the bottom surface of the flange portion 72, and becomes a portion that comes into contact with the sheet metal portion 23 when fixed to the sheet metal portion 23.

  The ribs 73 formed on the outer peripheral surface of the cylindrical portion 71 are periodically formed on the outer peripheral surface of the cylindrical portion 71 at predetermined intervals. In FIG. 7, the ribs 73 are formed at opposing positions on the outer peripheral surface of the cylindrical portion 71.

  As shown in FIG. 7C, the rib 72b protruding downward from the bottom surface of the flange portion 72 and the top surface portion of the rib 73 protruding from the outer peripheral surface of the cylindrical portion 71 have predetermined dimensions in the axial direction. There is a gap. This dimension e is a dimension that can be reliably inserted with respect to the thickness of the sheet metal member 23. In addition, the edge of the top | upper surface part of the rib 73 is cut in order to rotate with respect to the sheet-metal member 23, and to make it easy to insert as mentioned later. Thereby, the cross-sectional shape of the rib 73 in the vertical direction is a trapezoid.

  Next, the shape of the sheet metal member 23 used in the switch structure according to the present embodiment will be described in detail. As shown in FIG. 8A, the sheet metal member 23 is a metal material member having an outer shape that matches the shape of the storage portion 21 (see FIG. 2). At a predetermined position of the sheet metal member 23, a hole 23a into which the cylindrical portion 71 of the mold member 7 is inserted and a hole 23b for fixing the mold member 7 by a method described later are formed.

  As shown in FIG. 8B, the hole 23 a is formed with a substantially horizontally long shape in the length direction of the sheet metal member 23. The hole 23b is formed at a position slightly away from the hole 23a in the width direction, and has a vertically long outer shape in a direction orthogonal to the hole 23a. FIG. 8C shows an enlarged view of the region B shown in FIG.

  In FIG. 8C, the hole 23a is such that a hole 231 having a dimension into which the cylindrical portion 71 of the mold member 7 can be inserted and a rib 73 formed on the outer peripheral surface of the cylindrical portion 71 can pass through when inserted. It has an outer shape obtained by synthesizing with a hole 231 formed to ensure a gap.

  Next, a method for fitting the mold member 7 having the above-described shape to the sheet metal member 23 having the above-described hole will be described with reference to FIGS. 9 and 10. FIG. 9A is a perspective view showing an example of the assembly start state of the mold member 7. 9A, the cylindrical portion 71 of the mold member 7 is aligned with the hole 231 of the sheet metal member 23 and the position of the rib 73 is aligned with the position of the hole 232. It is pushed into the hole 23 a of the sheet metal member 23.

  FIG. 9B shows a plan view of the pushed state. In FIG. 9B, the rib 73 passes through the hole 232 and is pushed to the position where the bottom surface of the flange portion 72 contacts the top surface of the sheet metal member 23. The direction in which the leg portion 72a extends and the length direction of the hole 23b are orthogonal to each other.

  FIG. 9C shows a side view of the pushed state. 9C, the cylindrical portion 71 of the mold member 7 is passed through the hole 23a, and the rib 72b formed on the flange portion 72 and the rib 72c formed on the leg portion 72a are the top surface of the sheet metal member 23. The rib 73 formed on the outer peripheral surface of the cylindrical portion 71 is on the lower side of the sheet metal member 23. At this time, the top surface portion of the rib 73 is at a height position where it can be in close contact with the bottom surface side of the sheet metal member 23.

  Next, a process until the mold member 7 is fixed to the sheet metal member 23 will be described with reference to FIG. FIG. 10A is a plan view of the state shown in FIG. 9C as viewed from the top surface side of the flange portion 72. FIG.10 (b) is the top view which looked at the middle state which rotated the mold member 7 in the direction of the code | symbol R toward the fixed position from the state shown to Fig.10 (a) from the top | upper surface side. FIG.10 (c) is the top view which looked at the state which rotated the mold member 7 from the middle state of FIG.10 (b), and reached the fixed position from the top | upper surface side.

  FIG. 10D is a plan view of the state shown in FIG. 9C viewed from the bottom surface side of the sheet metal member 23. FIG. 10E is a plan view of the intermediate state in which the mold member 7 is rotated from the state shown in FIG. 10D toward the fixed position, as viewed from the bottom surface side of the sheet metal member 23. FIG. 10 (f) is a plan view of the state where the mold member 7 is further rotated from the middle state of FIG. 10 (d) to reach the fixed position as seen from the bottom surface side of the sheet metal member 23.

  As shown in FIGS. 10A and 10D, first, when the cylindrical portion 71 is inserted into the hole 23 a, the rib 72 b and the rib 72 c come into contact with the top surface side of the sheet metal member 23. At this time, the rib 73 passes through the hole 232 and is on the bottom surface side of the sheet metal member 23.

  From this state, the mold member 7 is rotated in the direction of the symbol R around the center point of the cylindrical portion 71 as an axis. 10B and 10E, the rib 73 comes into contact with the bottom surface side of the sheet metal member 23, and the rib 72b is in contact with the rib 73 and the top surface side of the sheet metal member 23. And the mold member 7 will be in the state which clamps the sheet metal member 23 by the rib 72c. That is, the mold member 7 is fixed in the axial direction by the ribs 72 b and 72 c formed on the flange portion 72 and the rib 73 formed on the cylindrical portion 71.

  When rotated further in the direction of the symbol R from the state of FIG. 10B and FIG. 10E, the leg 72a is fitted into the hole 23b as shown in FIG. 10C and FIG. 10F. It becomes a state to do. The rib 72c formed on the leg portion 72a is rotating while contacting the top surface side of the sheet metal member 72. Therefore, when the leg portion 72b comes to the position of the hole 23b, the flange 72c is opposed to the hole 23b. Depressed. That is, the flange 72c comes into contact with the inner peripheral surface of the hole 23b, and the mold member 7 cannot rotate. As a result, the mold member 7 is prevented from wobbling in the horizontal direction with respect to the sheet metal member 23.

  Thus, the mold member 7 has a shape that can be fixed to the sheet metal member 23 by a rotating operation at a predetermined position. Thereby, when fixing the mold member 7 to the sheet metal member 23, the hole 71a can be accurately formed according to the diameter of the boss 5a without deforming the cylindrical portion 71 of the mold member 7. Even when a biased load is applied to the operation button 5, the boss 5a can slide in the stroke direction with respect to the switch 50 using the hole 71a as a guide.

  FIG. 11 is a perspective view showing a state in which the mold member 7 is fixed to the sheet metal member 23. As shown in FIG. 11, in the mold member 7 according to the present embodiment, the wobbling in the horizontal direction is restricted by the flange portion 72 with respect to the sheet metal member 23, and the wobbling in the vertical direction (stroke direction) by the rib 73 (not shown). Regulated and fixed.

  Using the sheet metal member 23 to which the mold member 7 is fixed, the waterproof elastic member 22 is fixed to the housing 2 as shown in FIGS. 2 and 3, and the operation button 5 is inserted into the hole 71a of the mold member 7. The switch structure according to the present embodiment is formed by inserting the boss 5a and fixing the operation button 5 with the exterior member 8.

  According to the switch structure according to the present embodiment described above, even if the length of the operation button 5 in the stroke direction is increased, the boss 5a of the operation button 5 is accurately inserted into the hole 71a of the mold member 7. Thus, there is no wobbling of the operation button 5, and a pressing operation on the operation button 5 is also accurately transmitted to the switch 50. Therefore, even if the load applied to the operation button 5 is biased, the operability is not impaired and a reliable switch operation can be realized.

  Thus, according to the switch structure of the present invention, the waterproof performance is improved by securely fixing the elastic member with the sheet metal, and the length of the boss of the operation button in the stroke direction depends on the thickness of the elastic member and the sheet metal. Since the operation button wobbling caused by the increase in length can be prevented by the mold member rotated and fixed to the sheet metal member, both waterproofness and operability can be achieved.
