Description

The present invention relates to an imaging device such as a digital camera or a digital video camera, and more particularly to an imaging device having a pop-up strobe unit and a rotatable display unit.

In an imaging device such as a digital camera, a strobe unit that pops up in the height direction of the camera or the subject direction is widely known in order to avoid eclipse of the strobe light due to the extension of the lens barrel. As in Patent Document 1, there are various methods for detecting the storage position and the pop-up position of the strobe unit, such as a method using a photo reflector and a reflector, and a method using a magnet and a magnetic sensor such as a GMR sensor.

Further, as for the display unit, it is widely known that the display unit can be rotated and tilted to cope with various camera situations such as taking a selfie or raising the camera overhead from a crowd. The method of detecting the inverted state rotated by 180 ° to the storage position of the display unit and the position where self-portrait can be taken is as described in Patent Document 2, the magnet arranged on the rotation axis of the hinge and the GMR arranged on the display unit. Some are done with magnetic sensors such as sensors.

However, in Patent Document 1, the photo reflector and the reflector are used only for detecting the pop-up position of the strobe unit. Further, in Patent Document 2, although the opening / closing and rotation of the display unit are detected by using a magnet and a plurality of magnetic sensors, the detection is performed only on the display unit.

Many digital cameras are equipped with a pop-up strobe unit and a display unit that can rotate and tilt at the same time. If pop-up detection and rotation detection are configured independently, the number of parts will increase and space will be required. Become. For this reason, it causes an increase in size of the digital camera.

Further, when both the pop-up detection of the strobe unit and the rotation detection of the display unit are performed by using a magnet and a magnetic sensor, using a magnet having a relatively high unit price for each detection leads to an increase in cost.

Therefore, an object of the present invention is to provide an imaging device capable of detecting pop-up of a strobe unit and detecting rotation of a display unit at low cost without causing an increase in size.

In order to achieve the above object, the imaging device of the present invention holds a device main body, a magnet provided in the device main body, and a light emitting unit, and a protruding position exposed from the device main body in the height direction of the device main body. A strobe unit having a holding member that can move between the device and a storage position housed inside the device body, a first detection member provided on the holding member that detects a magnetic field of the magnet, and the device. It includes a display unit that is rotatably supported in the opening / closing direction with respect to the main body and is arranged in a stored position in a closed state, and a second detection member provided in the display unit that detects the magnetic field of the magnet. The first detection member and the second detection member are arranged so as to sandwich the magnet in a state where the holding member is arranged at the storage position and the display unit is arranged at the storage position. It is characterized by being.

According to the present invention, it is possible to provide an imaging device capable of detecting pop-up of a strobe unit and detecting rotation of a display unit at low cost without causing an increase in size.

Is formed. The cover member 501 serves as a cover for the holding member 504 and has an appearance when stored. The support frame 51 of the movable unit 50 at the time of pop-up is formed by fastening the sheet metal 511 and the appearance support member 512 to the holding sheet metal 508 with screws 513.

The rotary shaft 509 and the torsion spring 506 rotatably support the movable unit 50 with respect to the support frame 51 in a pop-up direction. Further, the rotating shaft 510 and the torsion spring 507 rotatably support the support frame 51 with respect to the base member 514 which is the base of the strobe unit 5 in a pop-up direction.

On the back side of the base member 514, a lever member 517 that moves the movable unit 50 from the storage position to the pop-up position is provided. The lever member 517 maintains its position by being guided by the standing bending portion 520a of the sheet metal member 520 with the compression spring 518, and is always urged to the front side.

The sheet metal member 520 is fixed to the base member 514 by a screw 521, and the elastic portion 520b of the sheet metal member 520 urges the protrusion 504b of the holding member 504 to the front side, so that the movable unit 50 is stable in the storage position without play. It is held in the position where it was. The magnet 519 has magnetic poles in the height direction of the camera body 1, and is placed on the back surface of the base member 514 in order to detect that the movable unit 50 of the strobe unit 5 is in the storage position and the rotation position of the display unit 8. It is fixed by adhesion or the like.

Further, on the back side of the base member 514, a strobe substrate 522 and a flexible substrate 523 connected to the strobe substrate 522 are provided. The flexible substrate 523 is electrically connected to the light emitting unit 503 of the movable unit 50 through the opening 514a of the base member. A first detection member 523a (523a') such as a GMR sensor or a Hall IC that detects the magnetic field of the magnet 519 is mounted on the back side of the flexible substrate 523.

A capacitor 516 is fixed to the front surface side of the base member 514 via a double-sided tape 515.

A conductive member 525 for establishing electrical conduction with the rotating shaft 510 is fixed to the side surface portion of the base member 514 by a screw 527 in a state of being sandwiched between the strap members 526.

Next, the display unit 8 will be described in detail with reference to FIGS. 6 and 7. 6 (a) is a perspective view of the display unit 8, and FIG. 6 (b) is a perspective view of the display unit 8 shown in FIG. 6 (a) as viewed from the back surface side. FIG. 7 is an exploded perspective view of the display unit 8.

As shown in FIGS. 6 and 7, in the display unit 8, the display panel 801 on the rearmost side is fixed to the holding frame 803 via the double-sided tape 802. The display panel 801 is provided with a flexible substrate 801a for the display unit and a flexible substrate 801b for the backlight. A second detection member 801c (801c') such as a GMR sensor or a Hall IC that detects the magnetic field of the magnet 519 described above is mounted on the back side of the flexible substrate 801b for the backlight.

A display board 804, a base member 805, and a sheet metal member 806 are provided on the front side of the holding frame 803, and the display board 804 is fastened with screws 808 and 812 so as to be sandwiched between the display panel 801 and the base member 805. As a result, the movable portion 80 is formed. A rotary hinge portion 807 is provided on the upper portion of the sheet metal member 806, and the movable portion 80 is about 180 ° with respect to the camera body 1 with the rotary hinge portion 807 as a rotation axis with respect to the sheet metal member 809 arranged on the front side. Can rotate within an angle.

The flexible substrate 801a for the display unit of the display panel 801 and the flexible substrate 801b for the backlight, and the flexible substrate 813 for making an electrical connection with the camera body 1 are connected to the display unit substrate 804 by a connector. Finally, the exterior cover member 814 is fastened to the sheet metal member 809 with screws 815 to complete the display unit 8.

The position of the second detection member 801c (801c') with respect to the display unit 8 is determined by incorporating the positioning hole 801d into the positioning boss 805a of the base member 805 in the flexible substrate 801b for the backlight. The display unit 8 is fixed to the back cover unit 7 by being screwed to the back cover unit 7 via a fixing sheet metal 811. Then, the movable portion 80, the sheet metal member 807, and the sheet metal member 809 can be integrally rotated with the rotation hinge portion 810 on the lower side of the sheet metal member 809 as a rotation axis within an angle of 45 ° on the lower side of the back surface.

FIG. 8A is a view of a digital camera in which the movable unit 50 of the strobe unit 5 and the movable portion 80 of the display unit 8 are both stored and viewed from the side cover unit 6 side of the camera body 1. FIG. 8B is a view of the movable unit 50 of the strobe unit 5 popping up from the camera body 1 and the movable portion 80 of the display unit 8 rotated 180 ° for self-portrait as viewed from the side cover unit 6. be.

When the movable unit 50 of the strobe unit 5 pushes down the strobe lever 601 of the side cover unit 6, the lever member 517 (FIG. 4) moves to the back side, and the protrusion 504b of the holding member 504 and the notch portion of the lever member 517 are cut out. The engagement of 517a (FIG. 5) is disengaged.

When this engagement is released, the torsion springs 506 and 507 urged in the pop-up direction raise the movable unit 50 to the protruding position shown in FIG. 8B with the shaft 509 and the shaft 510 as the rotation centers, respectively. The movable unit 50 is stored by manually pushing down the movable unit 50 to bring it into the state shown in FIG. 8A, and the protrusion 504b of the holding member 504 and the notch 517a of the lever member 517 are engaged again. That state is maintained (Fig. 5).

The movable portion 80 of the display unit 8 rotates around the rotation hinge portion 807 by manually lifting the lower surface 803a of the holding frame 803. Then, the upper surface 803b of the holding frame 803 of the movable portion 80 slides with the back surface of the upper surface cover unit 4, and the holding sheet metal 809 rotates about the rotation hinge portion 810 by an angle α, so that the position is reversed by 180 °. ..

Therefore, the accurate rotation angle of the movable portion 80 with respect to the holding sheet metal 809 is 180 + α °, which is the sum of 180 ° and the angle α of the holding sheet metal 809 rotated about the rotation hinge portion 810 as the center of rotation. The movable portion 80 is stored in the storage state shown in FIG. 8A by following a path opposite to the above by manually rotating and lowering the vicinity of the lower surface 803a of the holding frame 803.

In this way, when the storage state of FIG. 8A is changed to the pop-up state of the strobe unit 5 and the 180 ° rotation state of the display unit 8 of FIG. 8B, the states can be detected respectively. You will need it. In the case of the strobe unit 5, the strobe is emitted inside the camera body 1 when the movable unit 50 is stored, and heat is trapped in the strobe unit 50 to prevent scorching or melting in the peripheral portion of the movable unit 50. Further, in the case of the display unit 8, it is necessary to display an image inverted 180 ° with respect to the stored state so that the live image or the captured image displayed on the display panel 801 can be confirmed at the 180 ° inverted position. be.

In particular, the strobe unit 5 needs to prohibit light emission while the internal parts of the camera body 1 are present on the front surface of the movable unit 50. Since it is assumed that the movable portion 80 of the display unit 8 is rotated at a low angle until it is about to be completely inverted by 180 ° to confirm the image display, it is necessary to maintain the same display as in the stored state.

Therefore, in the present embodiment, in order to detect the position of the strobe unit 5 and the rotation of the display unit 8, one magnet 519, the first detection member 523a (523a'), and the second detection member 801c (801c') To use.

FIG. 9 is a front view of a digital camera in which the strobe unit 5 and the display unit 8 are stored. FIG. 10 is a cross-sectional view taken along the line AA of FIG.

As shown in FIG. 10, a magnet 519 is incorporated into the base member 514 of the strobe unit 5 from the back surface side and fixed by adhesion or the like. On the front side of the magnet 519, a first detection member 523a (523a') for detecting the storage of the movable unit 50 of the strobe unit 5 is provided. Further, on the back side of the magnet 519, a second detection member 801c (801c') for detecting the rotation of the movable portion 80 of the display unit 8 is provided.

In other words, the magnet 519 is sandwiched between the first detection member 523a (523a') of the strobe unit 5 and the second detection member 801c (801c') of the display unit 8 in the optical axis direction. With such an arrangement, the magnetic field of the magnet 519 is shared by the first detection member 523a (523a') of the strobe unit 5 and the second detection member 801c (801c') of the display unit 8, and is shared by one magnet 519. It is possible to satisfy each detection.

Next, the details of the storage detection of the strobe unit 5 and the rotation detection of the display unit 8 will be described with reference to FIGS. 11 to 18. FIG. 11A is a view of the movement locus of the first detection member 523a (523a') of the strobe unit 5 with respect to the magnet 519 as viewed from the side cover unit 6 side. FIG. 11B is a view of the movement locus of the second detection member 801c (801c') of the display unit 8 with respect to the magnet 519 as viewed from the side cover unit 6 side. Note that FIG. 11 shows a locus from the storage position of the strobe unit 5 to the pop-up position and from the storage position of the display unit 8 to the 180 ° inverted position. Further, in order to make it easy to understand the postures of the first detection member 523a (523a') and the second detection member 801c (801c'), the storage position is indicated by an upward arrow.

As shown in FIG. 11A, the first detection member 523a (523a') of the strobe unit 5 moves from the storage position to the upper surface side of the camera body 1, and then moves to the upper surface side of the camera body 1. While continuing, it moves to the front side of the camera body 1 and reaches the pop-up position. As shown in FIG. 11B, the second detection member 801c (801c') of the display unit 8 starts rotating counterclockwise from the storage position as shown by the arrow in the figure. Then, the camera body 1 rotates 90 ° at the position most moved to the upper surface side, and further rotates counterclockwise to reach the 180 ° reversal position. Here, the reason why the rotation locus of the second detection member 801c (801c') of the display unit 8 is not a circle is that, as described above, the rotation hinge portion 807 is the center of rotation and the rotation hinge portion 810 is the center of rotation. This is because the rotation of the sheet metal member 809 is also involved.

FIG. 12 is a diagram showing the distribution of magnetic field lines of the magnetic field generated from the magnet 519 to the strobe unit 5 side. FIG. 13 is a view of the movable unit 50 of the strobe unit 5 completely exposed from the camera body 1 as viewed from the front side of the camera body 1. In FIG. 12, the arrow indicates the direction of the magnetic field, and the darker the color of the line, the stronger the magnetic force, and the lighter the color, the weaker the magnetic force. Further, the first detection member 523a of the strobe unit 5 used here is assumed to be a magnetic sensor such as a GMR sensor capable of detecting a strong magnetic force in the upper surface side direction of the camera body 1.

The first detection member 523a of the strobe unit 5 moves from the storage position along the trajectory shown in FIG. 11A, and the magnetic field line of the arrow in the figure divides the detection on / off of the first detection member 523a on the way. It is a boundary. Therefore, as shown in FIG. 12, in the region until the threshold boundary is crossed, the first detection member 523a of the strobe unit 5 is in the detection on state, and when it exceeds this, the detection is off state. When the detection is turned on, the control unit (not shown) controls the strobe light of the strobe unit 5 to prohibit light emission.

When the first detection member 523a of the strobe unit 5 moves to the A position beyond the threshold boundary, the movable unit 50 of the strobe unit 5 is completely replaced with the light emitting unit 503 of the movable unit 50 as shown in FIG. It becomes exposed. At this position A, since there is no shield of strobe light on the front surface of the light emitting unit 503, heat is not trapped, and there is no possibility that the above-mentioned scorching or melting will occur.

By detecting the magnetic field of the magnet 519 in this way, even if the movable unit 50 of the strobe unit 5 is stored or the upper surface of the movable unit 50 is pressed and slightly popped up, light is emitted until the light emitting unit 503 is exposed. Can not. Therefore, the safety of the digital camera can be maintained.

FIG. 14 is a diagram showing the strong magnetic fields of the camera body 1 in the back side direction at equal intervals among the magnetic fields generated from the magnet 519 on the strobe unit 5 side. In FIG. 14, as in FIG. 12, it is shown that the darker the color of the line, the stronger the magnetic force, and the lighter the color, the weaker the magnetic force.

The magnetic field lines generated from the magnet 519 enter from the north pole to the south pole, but the magnetic force from the north pole to the center of the magnetic pole of the magnet 519 has no component force in the back side direction of the camera body 1, so it is on the north pole side. It looks as if no magnetic force is being generated. The first detection member 523a'of the strobe unit 5 used here is assumed to be a magnetic sensor such as a Hall IC capable of detecting a strong magnetic force in the back side direction of the camera body 1.

While the first detection member 523a'of the strobe unit 5 moves from the storage position along the trajectory shown in FIG. 11A, the magnetic field line of the arrow in the figure indicates the detection on / off of the first detection member 523a'. It is a threshold boundary that divides. Therefore, in the region until the threshold boundary is crossed, the first detection member 523a'of the strobe unit 5 is in the detection on state, and when it exceeds this, the detection is off state. When the detection is turned on, the control unit (not shown) controls the strobe light of the strobe unit 5 to prohibit light emission, as described above.

FIG. 15 is a graph showing the strength of the magnetic force (detected magnetic flux density) with respect to the rotation angle of the holding sheet metal 508 of the strobe unit 5 from the stored state. In FIG. 15, βmT coincides with the magnetic force at the threshold of FIG. 14, and when it exceeds βmT, it is in the detection on state, and when it exceeds βmT, it is in the detection off state. Further, the position B in FIG. 14 substantially coincides with the plot of the holding sheet metal 508 at a rotation angle of 40 °.

In this way, the position of the movable unit 50 of the strobe unit 5 can also be detected by detecting the magnetic field in the back side direction of the magnet 519. However, when detecting the magnetic field in the back side direction of the magnet 519, the first detection member 523a of the strobe unit 5 needs to be located on the upper surface side of the magnetic pole center of the magnet 519 in the retracted state. This is because, as described above, in the region of the N pole on the lower surface side of the center of the magnetic pole, the component force of the magnetic force in the back side direction disappears, and the detection is switched to the off state.

Therefore, when detecting the magnetic field in the back side direction of the magnet 519, the locus of the first detection member 523a'of the strobe unit 5 shown in FIG. 11A does not hold, and the position of the stored state is the magnetic pole of the magnet 519. It must be placed on the upper surface side of the center.

FIG. 16 is a diagram showing magnetic field lines of a magnetic field generated from the magnet 519 on the display unit 8 side, and arrows indicate the direction of the magnetic field. The second detection member 801c of the display unit 8 used here assumes a magnetic sensor such as a GMR sensor capable of detecting the magnetic force of the vector in the upper surface side direction of the camera body 1.

While the second detection member 801c of the display unit 8 moves from the storage position along the locus shown in FIG. 11B, the vector in the upper surface side of the magnetic field extends from the storage position to the C1 position rotated by 90 °. Since there is no second detection member 801c, the detection off state is maintained. When the display unit 8 continues to rotate and reaches the vicinity of C2, the magnetic field line of the arrow is the threshold boundary that separates the detection on / off of the second detection member 801c. Therefore, when the threshold boundary is crossed, the detection is turned on and displayed. The display image of the panel 801 is inverted.

FIG. 17 is a graph showing the strength of the magnetic force (detected magnetic flux density) with respect to the rotation angle of the movable portion 80 of the display unit 8. As shown in FIG. 17, since the boundary value of the detection magnetic flux density of the second detection member 801c of the display unit 8 is γmT, the detection is still off at the C2 position at the rotation angle of 160 °, and the rotation angle is 170. It switches to the detection on state until it moves to the C3 position of °.

As described above, since it is desirable that the movable portion 80 of the display unit 8 switches to the detection on state just before the 180 ° inversion position, a rotation angle of 160 ° is provided with a detection margin so that the display image is not inverted. It is better to set it so that it switches around ~ 170 °. By detecting the magnetic field in the height direction of the camera body 1 in this way, it is possible to maintain comfortable operability and visibility of the display unit 8 of the camera body 1.

FIG. 18 is a diagram showing the strong magnetic fields of the camera body 1 in the front side direction at equal intervals among the magnetic fields generated from the magnet 519 on the display unit 8 side. The magnetic field lines generated from the magnet 519 enter from the north pole to the south pole, but the magnetic force from the north pole to the center of the magnetic pole of the magnet 519 has no component force in the front side direction, so that the magnetic force is generated on the north pole side. It looks as if it isn't there. The second detection member 801c'of the display unit 8 used here assumes a magnetic sensor such as a Hall IC that can detect the magnetic force of the vector in the front side direction of the camera body 1 when the display image is inverted.

Unlike the case of FIG. 16, when the second detection member 801c'is in the D1 position slightly rotated from the storage position, a component force of the magnetic force in the back side direction, which is not shown in the figure, is generated, but the threshold is generated. It is a weak magnetic force that does not reach the boundary and the direction of the magnetic field is opposite. Therefore, the second detection member 801c'of the display unit 8 is in the detection off state.

Further, when the display unit 8 rotates and exceeds the center of the magnetic pole to the D2 position where the rotation angle is 90 °, the detection direction of the second detection member 801c'and the direction of the magnetic field are reversed, so that the detection is not detected and the detection is off. It has become. Further, the magnetic force is detected at the D3 position, the D4 position, and the 180 ° inverted position beyond the threshold boundary until the display unit 8 rotates and reaches the D3 position, and the detection is turned on. In this way, the rotation of the movable portion 80 of the display unit 8 can also be detected by detecting the magnetic field in the thickness direction of the camera body 1.

In the present embodiment, the magnetic field in which the detection on / off is switched is set as a fixed value for both the first detection member 523a (523a') and the second detection member 801c (801c'). It is necessary to secure. When it is mounted on a flexible substrate or the like and the detection variation of the detection member itself, it is necessary to consider the mounting deviation and arrange it appropriately.

As described above, in the present embodiment, one magnet 519, which is relatively expensive and requires an arrangement space, is sufficient for pop-up detection of the strobe unit 5 and rotation detection of the display unit 8. Therefore, it is possible to provide a digital camera capable of pop-up detection of the strobe unit 5 and rotation detection of the display unit 8 at low cost without causing an increase in size.

The configuration of the present invention is not limited to that illustrated in the above embodiment, and the material, shape, dimensions, form, number, arrangement location, etc. can be appropriately changed as long as the gist of the present invention is not deviated. Is.

For example, in the above embodiment, the movable portion 80 of the display unit 8 is rotated by 180 ° in the opening / closing direction and the lower side is rotated by 45 ° to set two axes, but the movable portion 80 is rotated only by 180 ° in the opening / closing direction. It may be a digital camera with a single axis setting.

Further, in the above embodiment, the magnet 519 is covered with the top cover, but the magnet 519 may be covered with the back cover. In that case, both the material of the upper surface cover and the material of the back cover need to be a non-magnetic material that does not block the magnetic field of the magnet 519.

Further, the pop-up detection of the strobe unit 5 and the rotation detection of the display unit 8 can be detected in the height direction of the camera body 1 or in the thickness direction of the camera body 1 if the above-mentioned conditions are satisfied. The combination can be changed freely.
