Description

  The present invention relates to an imaging apparatus and an imaging system including an accessory mounting portion on which an accessory is detachably mounted.

  Some imaging apparatuses such as video cameras include an accessory mounting portion such as an accessory shoe formed by bending both sides of a flat plate inward. Various accessories are replaceably attached to the accessory attaching portion and fastened by fastening means such as screws (Patent Document 1).

  In addition, various arrangement forms of accessories are required. For example, there is an arrangement mode in which a display panel as an accessory is attached to a handle provided on the upper surface of the apparatus main body, in addition to the display surface facing the photographer side on the back side of the imaging apparatus main body or the side of the apparatus main body. In some cases, an optical finder is attached to the display panel in order to check the shooting contents in a bright environment. In order to realize such various arrangement forms of the display panel, a hinge unit having a high degree of freedom may be arranged between the apparatus main body and the display panel.

  It is important that the hinge unit has a configuration that can be stably held in a desired posture of the display panel. For example, it is required that the display panel is not easily rotated by a slight operation load from the photographer side in an arrangement state in which the display surface faces the photographer side. A technique for suppressing the rotation by fixing the rotation shaft of the hinge unit with a screw is known (Patent Document 2).

  Furthermore, when connecting a display panel as an accessory via a hinge unit attached to the imaging device main body with a handle, it is desirable that the display panel can be changed in posture and placed beside the handle or above the handle. In addition, it is required that the display unit of the display panel be directed to the photographer side, or the display panel can be placed in the retracted state with the display unit facing the imaging apparatus body.

  In response to such a request, a technique is known in which the display panel and the operation unit are rotatable with respect to the attachment unit, and the user can operate the operation unit while facing the display panel (Patent Document 3). . Further, in the configuration of Patent Document 2, the display panel can be rotated around a support shaft that protrudes in the horizontal direction from the main body of the imaging device, and the distance from the support shaft to the display panel can be adjusted.

  There is also known a configuration in which the hinge unit can be attached to and detached from the imaging apparatus main body and the display panel. In such a configuration, signal communication between the display panel and the imaging apparatus main body is generally realized by connecting a signal cable drawn out from the display panel to the imaging apparatus main body. For example, in the configuration of Patent Document 2, a cable is drawn from the side surface of the display panel and connected to the imaging apparatus main body.

It has been.

  When an attachment error occurs at the two first fitting portions 202 in the optical axis direction on the camera body 103 side, the two first fitting portions 202 may not be kept parallel. In that case, when two second fitting portions 204 are provided on the handle portion 104 side, either one of the second fitting portions 204 rides on the first fitting portion 202 on the camera body 103 side without being unevenly fitted. This causes a malfunction.

  Therefore, the handle portion 104 is provided with a concave and convex second fitting portion 204 only around the first screw insertion hole 203, and the first fitting on the camera body 103 side is provided around the second screw insertion hole 205. A receiving rib 206 is provided at a position avoiding the joint portion 202. The receiving rib 206 is formed in the first direction in the direction connecting the second screw insertion hole 205 and the first screw insertion hole 203 so as to contact the upper surface portion of the camera body 103 at a position avoiding the first fitting part 202 on the camera body 103 side. Two in total are arranged one by one before and after the two screw insertion holes 205.

  The receiving rib 206 is in contact with the upper surface portion of the camera body 103 at a position where the second fitting portion 204 and the first fitting portion 202 on the camera body 103 side are engaged with each other and a height of the camera body 103. It is provided so as to be approximately the same level in the direction.

  In contact by uneven fitting between the first fitting portion 202 on the camera body 103 side and the second fitting portion 204 on the handle portion 104 side, a larger frictional force can be obtained as compared with the conventional contact between flat surfaces. it can. For this reason, even if a force is applied to the handle portion 104 in the rotational direction for loosening the fastening by the screw members 105 and 106, the fastening by the screw members 105 and 106 can be suppressed from loosening.

  In particular, as described above, the handle portion 104 can be simply fastened to the camera body 103 with only the first screw member 105. In this case, with only the fastening force by which the operation dial of the first screw member 105 is turned by hand, the friction force is small when the two flat surfaces are brought into contact with each other, and when the rotational force is applied to the handle portion 104, the first screw member Looseness is likely to occur in the fastening by 105.

  On the other hand, as in this embodiment, in the contact by the concave and convex fitting between the first fitting portion 202 on the camera body 103 side and the second fitting portion 204 on the handle portion 104 side, the operation dial of the first screw member 105 is used. A large frictional force can be obtained with a small fastening force that is turned by hand. For this reason, even if a force is applied to the handle portion 104 in the rotational direction for loosening the fastening by the first screw member 105, the fastening state by the first screw member 105 can be suppressed from loosening.

  4A is a partial side view of the right side when the digital video camera 101 is viewed from the front side, and FIG. 4B is an enlarged cross-sectional view taken along line AA of FIG. 4A.

They are arranged in a phase that coincides with the center line 301 of the member 105. Accordingly, as shown in FIG. 2B, even if the handle portion 104 is rotated 180 ° with respect to the camera body 103 and attached in the opposite direction and fastened with the first screw member 105, the first fitting portion 202 is obtained. And the second fitting part 204 can be concavo-convexly fitted.

  As described above, in this embodiment, since the looseness of the handle portion 104 fastened to the accessory mounting portion 107 of the camera body 103 can be suppressed, stable transportation when gripping and transporting the handle portion 104 is possible. Is possible.

  In this embodiment, the handle portion 104 is fastened to the camera body 103 by bringing the fitting portions 202 and 204, in which a plurality of ridges having a right angled isosceles triangle section in parallel, are brought into contact with each other by concave and convex fitting. However, it is not limited to this. That is, the uneven fitting structure of the contact portion may be another fitting structure as long as a large frictional force can be obtained with a small fastening force.

  In the present embodiment, the receiving rib 206 is provided at a position around the second screw insertion hole 205 on the handle portion 104 side and avoiding the first fitting portion 202 on the camera body 103 side, but the present invention is not limited to this.

  9A and 9B are exploded perspective views of the accessory group and the hinge subunit 57, respectively. For the sake of explanation, the handle 4 is also shown in FIG. The hinge unit 5 can be separated and connected to the handle 4 by known screw fastening. The hinge unit 5 includes a base unit 56 and a hinge subunit 57, which are connected by known screw fastening (FIG. 9A). The hinge subunit 57 has arm portions 52, 53, 54, 55 in addition to the rotation shaft members 511, 512, 513 having a constant rotational torque. The respective rotation centers of the rotation shaft members 511, 512, and 513 correspond to the shaft centers of the rotation shafts 511a, 512a, and 513a. The arm portion 54 can be rotated around the rotation shaft 511 a with respect to the arm portion 55. The arm portion 53 can be rotated around the rotation shaft 512 a with respect to the arm portion 54. The arm portion 52 can be rotated around the rotation shaft 513 a with respect to the arm portion 53. The arm part 53 has a convex part 531 (second engaging part).

  The arm portion 52 can be attached to and detached from the display panel 3. The base unit 56 and the arm portion 55 serve as a first member that can be attached to and detached from the main body unit 100. The arm portion 54 is a second member that is rotatable with respect to the arm portion 55 via the rotation shaft 511a. The arm portion 53 is a third member that is rotatable with respect to the arm portion 54 (second member) via the rotation shaft 512a. When the accessory group is mounted on the apparatus main body 2, the rotation shaft 511 a is substantially parallel to the optical axis of the lens 11, and the rotation shaft 513 a is substantially parallel to the longitudinal direction of the display panel 3. The rotation shaft 512a is always substantially orthogonal to both the rotation shaft 511a and the rotation shaft 513a.

  FIG. 10A is a perspective view of the hinge unit 5 and the display panel 3 in the second arrangement when viewed from the bottom surface side. FIG. 10B is a bottom view of the hinge unit 5 and the display panel 3 in the second arrangement.

  Incidentally, the display panel 3 and the arm portion 52 can be a “rotating body” that rotates together with respect to the rotation operation centering on each of the rotation shaft 511a and the rotation shaft 512a. In addition, regarding the rotation operation from the first arrangement around the rotation axis 512a to the second arrangement direction, the arm portion 53 also rotates together with the rotation body. The rotation position around the rotation shaft 511a is common to all of the first, second, and third arrangements, and this is referred to as “predetermined rotation position”. The predetermined rotation position is a rotation position where the axial direction of the rotation shaft 512a is parallel to the vertical direction.

  On the lower surface of the base unit 56, a convex portion 561 (first engaging portion) corresponding to the convex portion 531 is provided. In the second arrangement, the abutting surface 532 of the convex portion 531 is opposed to the abutting surface 562 of the convex portion 561. In other words, the rotating body including the display panel 3 is projected to the projecting portion 561 while being rotated from the first arrangement to the third arrangement while being in a predetermined rotating position around the rotating shaft 511a. 531 contacts. Thereby, the rotating body is restricted from rotating in the direction of the third arrangement and is positioned in the second arrangement. The convex portion 531 functions as a rotation stopper, and it is avoided that the arm portion 53 easily rotates even when the display panel 3 receives the load F from the photographer side in the second arrangement. The load F is, for example, a load generated when a touch operation is performed on the display unit 31 or a face is pressed against the external viewfinder 7 attached to the display panel 3. FIG. 11 shows a state in which the external viewfinder 7 is attached to the display panel 3.

  In order to make a transition from the second arrangement to the third arrangement, it is necessary to release the engagement between the contact surface 532 of the convex portion 531 and the contact surface 562 of the convex portion 561. FIG. 12A is a view of the display panel 3 in which the arm portion 54 is rotated about 45 ° in the B direction from the second arrangement when viewed from the subject side (in the direction of arrow F ′ in FIG. 11). FIG. 12B is a view of the vicinity of the rotating shaft member 512 as seen from the direction of arrow C in FIG. As shown in FIG. 12A, the user moves the arm portion 54 around the rotation shaft 511a in the B direction (counterclockwise when viewed from the subject side, and the free end of the display panel 3 is displaced upward. ). Then, the engagement between the convex portion 531 and the convex portion 561 is released, and the arm portion 53 can be rotated around the rotation shaft 512a. Thereafter, as shown in FIG. 12B, the user rotates the arm portion 53 about the rotation shaft 512a in the A direction (the third arrangement direction with respect to the rotation around the rotation shaft 512a). Then, the display panel 3 rotates in the E direction together with the arm portion 53, and transitions to the position shown in FIG. The user rotates the arm portion 53 to the position shown in FIG. 13, and then turns the arm portion 54 around the rotation shaft 511a in the direction of the arrow B ′ opposite to the B direction in FIG. (Fig. 8 (c)). That is, when the display panel 3 is in the second arrangement, the projecting portion 531 and the projecting portion 561 are changed by temporarily changing the pivot position around the pivot shaft 511a from the predetermined pivot position in the B direction. Is disengaged and the display panel 3 can be shifted to the third arrangement. As a result, it is possible to perform the fixing and unlocking operations in the second arrangement with a simple operation.

  FIG. 14 is a perspective view of the hinge unit 5 and the display panel 3 in the third arrangement when viewed from the bottom surface side. The convex portion 561 is formed with a gradient 563 that forms a tapered surface in which the protruding height toward the lower surface side gradually changes. The gradient 563 is formed on the opposite side of the contact surface 562 with respect to the rotation shaft 512a. That is, in the convex portion 561, when the display panel 3 is rotated from the first arrangement to the third arrangement direction while being in a predetermined rotational position, the side opposite to the side in contact with the convex portion 531 is A gradient 563 is formed.

  When the user rotates the arm portion 53 in the third arrangement in the direction of the arrow A ′ opposite to the A direction around the rotation axis 512a, the arm portion 54 rotates about the rotation axis while the convex portion 531 follows the gradient 563. Rotating in the B direction around 511a, the convex portion 531 gets over the convex portion 561. That is, when the convex portion 531 is engaged with the convex portion 561 while the display panel 3 is being rotated from the third arrangement to the first arrangement while being in a predetermined rotational position, the slope is a tapered surface. The display panel 3 is energized by the action of 563. That is, the display panel 3 is urged in a rotation direction in which the engagement of the convex portions 531 and 561 is released with the rotation shaft 511a as the center. Thereby, even if the user does not intentionally rotate the arm portion 54 around the rotation shaft 511a, it is possible to easily shift from the third arrangement to the second arrangement or the first arrangement. Become.

  Thus, the display panel 3 can take various postures by the three-axis rotation mechanism, and has a high degree of freedom. In addition, it is possible to stably maintain the second arrangement suitable for photographing, and it is also easy to make a transition from the second arrangement to the third arrangement and a transition from the third arrangement to the second arrangement.

The semi-cylindrical part 5462 covers the intermediate part 5123 of the rotating shaft member 512 (FIG. 17C). A boundary K1, which is a joint between the semicylindrical part 5451 and the semicylindrical part 5461, is located around the intermediate part 5113 (FIG. 19B). A boundary K2 that is a joint between the semi-cylindrical part 5542 and the semi-cylindrical part 5462 is located around the intermediate part 5123 (FIG. 18C).

  As shown in FIG. 18A, the operator assembles the cover 535 from the one end portion 5131 side of the rotation shaft member 513 along the axis of the rotation shaft 513a. Next, the operator assembles the cover 536 from the other end 5132 side of the rotation shaft member 513 along the axis of the rotation shaft 513a. The cover 535 almost completely covers one end portion 5121 (FIG. 15) of the rotating shaft member 512, one end portion 5131 of the rotating shaft member 513, and the sheet metal member 534. The cover 535 has semi-cylindrical portions 5351 and 5352 each having a substantially semi-cylindrical shape. The semi-cylindrical part 5351 covers an intermediate part 5133 (intermediate part in the axial direction of the rotary shaft 513a) of the rotary shaft member 513 sandwiched between the flat part 5342 and the flat part 5241 (FIG. 18B).

Further, since the cover alignment between the cover 525 and the cover 526 and the cover alignment between the cover 535 and the cover 536 are arranged around the intermediate portion 5133, the cover alignment is not conspicuous and the appearance is improved (FIG. 20B). ).

  According to the present embodiment, the display panel 3 is placed on the convex portion 561 while being rotated from the first arrangement to the third arrangement while being in a predetermined rotation position around the rotation shaft 511a. The convex part 531 contacts. The convex portion 531 functions as a rotation stopper and regulates the rotation of the display panel 3 in the direction of the third arrangement and positions the display panel 3 in the second arrangement. Thereby, the rotation position of the display panel 3 can be stably fixed in the second arrangement. Thereafter, the user changes the rotation position of the display panel 3 around the rotation shaft 511a from the predetermined rotation position to the B direction (FIG. 12), thereby engaging the protrusions 531 and 561 with each other. And the display panel 3 can be shifted to the third arrangement. Therefore, it is possible to perform the fixing and unfixing operations in the second arrangement of the display panel 3 with a simple operation.

  Further, when the display panel 3 is rotated from the third arrangement to the first arrangement while being in the predetermined rotation position, the convex portion 531 gets over the convex portion 561 by the action of the gradient 563 that is a tapered surface. The engagement of the convex portions 531 and 561 is released. Thereby, the operation of changing the display panel 3 from the third arrangement to the second arrangement or the first arrangement becomes easy.

In this case, the tapered surface is formed on the convex portion 531 or the convex portion 561 on the opposite side to the side where the display panel 3 contacts with each other when the display panel 3 rotates from the first arrangement to the third arrangement.

(Third embodiment)
FIG. 21 is a perspective view of an imaging system according to the third embodiment of the present invention. The configurations of the apparatus main body 2 and the display panel 3 are the same as those in the first embodiment. The hinge unit 5 has arm portions 82 and 83 instead of the arm portions 52 and 53 with respect to the first embodiment, and the configuration of the other portions is the same as that of the first embodiment. . The arm portion 82 and the arm portion 83 are different from the arm portions 52 and 53 in that clamp members 88 and 89 are provided, respectively. Since the clamp members 88 and 89 have the same configuration, the clamp member 88 will be described as a representative.

  FIG. 22 is a view showing the clamp member 88. The clamp member 88 includes a main portion 881 having a substantially U-shaped portion and a locking portion 882 that can be bent with respect to the main portion 881. The clamp member 88 can stably hold the rod-shaped member 61 including a cylindrical shape. The clamp member 88 can hold the rod-shaped member 61 so that the axial center direction of the rod-shaped member 61 is substantially parallel to the axial direction of the rotation shaft member 513 (the rotation shaft 513a). In the direction orthogonal to the axial direction of the rotation shaft 513a, the distance from the center position of the rotation shaft 513a to the axis position of the clamp member 88 is from the center position of the rotation shaft 513a to the axis position of the clamp member 89. It is almost equal to the distance. Therefore, the clamp members 88 and 89 can hold the common rod-shaped member 61 by matching the relative rotational positions of the arm portions 82 and 83 and matching the axial centers of the clamp members 88 and 89.

  In FIG. 21, the display panel 3 is in the second arrangement. In this position, the clamp members 88 and 89 are adjacent to each other in a coaxial positional relationship. When the clamp members 88 and 89 are in a coaxial relationship with each other and hold the rod-shaped member 61 on both, the relative rotation between the arm portion 82 and the arm portion 83 around the rotation shaft 513a is restricted. it can. In the present embodiment, as shown in FIG. 23, in the second arrangement, the flexible portion of the signal cable 6 is held by the clamp members 88 and 89 at the same time instead of the rod-shaped member 61, thereby rotating the arm portion 82. Movement can be suppressed. In this way, even if the display panel 3 receives a load from the vertical direction, the arm portion 82 does not easily rotate. Further, as shown in FIG. 23, even when an accessory such as the external viewfinder 7 is attached to the display panel 3, it is possible to prevent unintentional rotation of the display panel 3 due to the mass of the accessory.

  According to the present embodiment, the same effects as those of the first embodiment can be achieved with respect to enabling the operation of fixing and unlocking the display panel 3 in the second arrangement with a simple operation. it can. Further, the rotation of the display panel 3 can be restricted by holding the common bar-shaped member in the clamp members 88 and 89. In addition, the normal operation of holding the signal cable 6 can restrict the rotation of the display panel 3 without increasing the number of components, and the troublesome handling of the signal cable 6 can be reduced.

  In the present embodiment, the rotation restriction between the arm portions 82 and 83 is taken as an example, but the present invention is not limited to this. Accordingly, among the components included in the rotating body, for example, a plurality of rotating members interposed between the display panel 3 and the main unit 100, the first rotation that is relatively rotated with respect to a predetermined rotation axis. Clamp members 88 and 89 may be provided on the member and the second rotating member. For example, the above configuration may be applied between the arm portions 53 and 54 and between the arm portions 54 and 55. In the example shown in FIGS. 21 to 23, the rotation shaft 513a among the plurality of rotation shafts is a predetermined rotation shaft, the first and second rotation members are the arm portions 82 and 83, and the first The second holding parts are clamp members 88 and 89. In addition, you may prepare the rod-shaped member 61 separately for rotation control.

  Note that the hinge unit 5 has a configuration having at least two rotation shafts as long as the effect of enabling the operation of fixing and unlocking the display panel 3 in the second arrangement is possible with a simple operation. If it is. The rotating body connected to the main unit 100 so as to be rotatable about each of at least two rotating shafts is not limited to the display panel 3 and may be other accessories.

  Note that a part or all of the above-described imaging system configured symmetrically may be used as the imaging system of the present invention.

  FIGS. 27A and 27B are exploded perspective views of the display panel 3. In the display panel 3, from the display unit 31 side, the display unit 31, the exterior cover 315, the display module 311, the backlight 314, the display module holding member 316, the circuit board 39, the connection terminal 34, and the back side exterior cover 322 are arranged in this order. Be placed. The display module 311, the display unit 31, the operation key group 313, and the backlight 314 are connected to connectors 393, 394, 395, and 396 mounted on the circuit board 39, respectively.

  FIG. 28A is a rear view of the display panel 3 to which the signal cable 6 is connected. 28B and 28C are a perspective view and a rear view, respectively, of the display panel 3 in which the rear side exterior cover 322 is not shown. The signal cable 6 is arranged so as to be drawn out from the connection terminal 34 and to extend toward the side where the fixing portion 331 is located, that is, the side surface 353 (FIG. 28A).

  A circuit board 39 is built in the display panel 3. The circuit board 39 displays an electrical signal sent from the image sensor 12 as a through image, or transmits an input signal from the touch panel, the operation key group 313 or the display inversion key 37 of the display panel 3 to the apparatus body 2. Process. The element 391 mounted on the circuit board 39 performs most of these processes. Therefore, the element 391 is an element that consumes the largest power among the components and elements in the display panel 3 and is a main heat generating portion. The connectors 392 to 396 are disposed closer to the display unit 31 than the element 391 in the thickness direction of the display panel 3. Input signals from the touch panel of the display unit 31, the operation key group 313, and the display inversion key 37 are input to the element 391 from the connectors 394, 395, and 396, respectively, and various processes are performed. Is output.

  A wire 341 of the connection terminal 34 is connected to the connector 392. The electrical signal sent from the image pickup device 12 enters the circuit board 39 from the connector 392, is input to the device 391, is subjected to various processes, and then sent to the display module 311 via the connector 393. The connection terminal 34 is disposed in the vicinity of the center position B in the short direction of the display panel 3. The element 391 is arranged and mounted at a position facing the convex portion 38 including the connection terminal 34 and the grip portion 62 of the signal cable 6 with the back surface side exterior cover 322 interposed therebetween.

  Since the power consumption of the element 391 is the highest among the elements in the display panel 3, the temperature distribution of the backside exterior cover 322 is the highest in the region where the element 391 is projected on the back surface 32 in a direction perpendicular to the element. Here, the convex portion 38, the signal cable 6, and the element 391 overlap each other when viewed from the direction perpendicular to the display portion 31 (FIG. 28A). That is, the convex portion 38 and the grip portion 62 of the signal cable 6 are arranged so as to overlap the display portion 31 with a projection in a direction perpendicular to a region where the temperature may be relatively high. Thereby, it becomes a structure which a photographer cannot touch easily the area | region where temperature may become comparatively high during imaging | photography, and a photographer's discomfort is suppressed.

  Next, a typical arrangement form (posture) of the display panel 3 with respect to the apparatus main body 2 will be described with reference to FIGS. 29, 30, 31, and 32 are diagrams of imaging systems in which the display panel 3 is set to the first imaging position, the second imaging position, the first storage position, and the second storage position, respectively. 29 to 32, the hinge unit 5 is fixed to the handle 4 and the display panel 3, and the display panel 3 is electrically connected to the apparatus main body 2 via the signal cable 6.

  First, the first photographing position is an arrangement in which the display unit 31 of the display panel 3 faces the photographer side on the side (left side) of the handle 4 of the main unit 100. 29A, 29B, and 29C are a perspective view of the main unit 100, a view seen from the subject side along the optical axis A, and a top view, respectively. The flexible portion 61 is held by a clamp member 567 provided in the hinge unit 5, thereby preventing the flexible portion 61 from coming into contact with the lens barrel 1 or entering the angle of view. The rotation shaft 511 a is substantially parallel to the optical axis A, and the rotation shaft 513 a is substantially parallel to the longitudinal direction of the display panel 3. The rotation shaft 513a is substantially orthogonal to the side surface 351 and the side surface 353 and is substantially parallel to the display unit 31 (display surface thereof). The rotation shaft 512a is always substantially orthogonal to both the rotation shaft 511a and the rotation shaft 513a.

  As shown in FIG. 29C, the signal cable 6 extends toward the side surface 353 substantially in parallel with the back surface 32. Accordingly, the flexible portion 61 does not protrude from the display panel 3 and the area occupied by the flexible portion 61 is small as in the case where the signal cable 6 is extended vertically to the back surface 32 (indicated by reference numeral 612). I'll do it.

  FIGS. 30A and 30B are a perspective view of the main unit 100 at the second photographing position and a view from the subject side along the optical axis A, respectively. In the second imaging position, the display panel 3 is located above the handle 4. When the arm portion 54 is rotated 180 ° from the first photographing position in the C direction (counterclockwise as viewed from the subject side) shown in FIG. 30B around the rotation shaft 511a, the second photographing position is obtained. Transition.

  As shown in FIG. 29B, in the vertical direction, the distance between the upper end position of the main unit (the upper surface 43 of the handle 4) and the center position of the rotation shaft 511a is L1. Further, when the display panel 3 is located at the first photographing position, the distance between the upper end position (here, the side surface 352) of the display panel 3 and the center position of the rotation shaft 511a in the vertical direction is L2. Here, the distance L1 is substantially equal to the distance L2, and substantially coincides (L1≈L2). Therefore, when the display panel 3 is rotated 180 ° about the rotation axis 511a to be the second imaging position, the lower end position (the side surface 352 here) of the display panel 3 is the upper end position (the upper surface 43) of the handle 4. (Fig. 30 (b)). Thereby, size reduction of the whole imaging system in the up-down direction is achieved. In the vertical direction, the positions of the upper end of the base unit 56 of the hinge unit 5 and the upper surface 43 of the handle 4 are substantially equal.

  The photographer can change the display panel 3 between the first photographing position and the second photographing position by a simple single operation. Moreover, the side surface 351 becomes a free end part regarding the rotation around the rotation axis 511a. Since the connection terminal 34 is disposed in the vicinity of the free end portion, the area occupied by the flexible portion 61 can be small. If the connection terminal 34 is disposed at another position (for example, the position indicated by reference numeral 342 in FIG. 30B), the flexible portion 61 protrudes from the display panel 3 (reference numeral 613 in FIG. 30B). As shown, the area occupied by the flexible portion 61 increases and the flexible portion 61 becomes difficult to handle.

  By the way, by moving the hinge subunit 57 in the range of the length L of the slit shape 563 (FIG. 2C) of the sheet metal member 562, the handle 4 and the display panel in the left-right direction at the first and second photographing positions. 3 can be adjusted. For example, the center 44 of the handle 4 in the left-right direction and the center 317 of the display unit 31 in the longitudinal direction of the display unit 31 can be substantially coincided with each other at the second photographing position. The center 44 of the handle 4 is designed to coincide with the optical axis A. Therefore, the photographer can shoot with an arrangement in which the grip position of the handle 4, the optical axis A, and the center 317 of the display unit 31 are substantially matched.

  As shown in FIG. 29B, when the display panel 3 is in the first photographing position, the rotation shaft 511a is positioned above the upper end position (here, the side surface 352) of the display panel 3, and It is located closer to the optical axis A than the side surface 353 in the direction. When the display panel 3 is in the first photographing position, the rotation shaft 512a is positioned closer to the optical axis A than the rotation shaft 511a in the left-right direction. As shown in FIG. 29C, the three rotation shaft members are positioned in the order of the rotation shaft members 513, 512, and 511 from the subject side.

  31A, 31B, and 31C are a perspective view, a left side view, and a left side view, respectively, of the main unit 100 at the first storage position. In the first storage position, the display panel 3 is positioned above the handle 4, and the display unit 31 faces the base unit 56 and the handle 4. When the arm 52 is rotated from the second photographing position (FIG. 30) in the D direction (clockwise as viewed from the left) shown in FIG. 31 (b) around the rotation shaft 513a, the first storage is performed. Transition to position. If the signal cable 6 is extended in a direction perpendicular to the back surface 32, the flexible portion 61 protrudes greatly (indicated by reference numeral 614 in FIG. 31B). However, in the present embodiment, the signal cable 6 extends toward the side surface 353 substantially parallel to the back surface 32. Therefore, the area occupied by the flexible portion 61 when the signal cable 6 rotates around the rotation shaft 513a can be small.

  The rotating shafts 511a, 512a, and 513a each have a constant torque and can hold the display panel 3 at an arbitrary position. Therefore, as shown in FIG. 31 (c), it is possible to hold the display panel 3 between the second photographing position and the first storage position, and thus the finger rest portion 42 is exposed. Therefore, it is easy for the photographer to carry the handle 4 by hand.

  32A and 32B are a perspective view and a top view of the main unit 100 in the second storage position, respectively. In the second storage position, the display unit 31 is located on the side (left side) of the handle 4 and faces the handle 4. When the arm portion 53 is rotated from the first photographing position (FIG. 29) in the E direction (counterclockwise as viewed from above) shown in FIG. 32B around the rotation shaft 512a, the second storage is performed. Transition to position. If the signal cable 6 is extended in a direction perpendicular to the rear surface 32, the flexible portion 61 protrudes greatly from the display panel 3 (indicated by reference numeral 615 in FIG. 32B). However, in the present embodiment, the signal cable 6 extends toward the side surface 353 substantially parallel to the back surface 32. Therefore, the area occupied by the flexible portion 61 when the signal cable 6 rotates around the rotation shaft 512a can be small.

  Moreover, the side surface 351 becomes a free end part regarding the rotation around the rotation axis 512a. Since the connection terminal 34 is disposed in the vicinity of the free end portion, the area occupied by the flexible portion 61 can be small. For example, if the connection terminal 34 is disposed at another position (position indicated by reference numeral 343 in FIG. 32B), the flexible portion 61 protrudes from the display panel 3 (indicated by reference numeral 616 in FIG. 32B). ), The area occupied by the flexible portion 61 becomes large and the flexible portion 61 becomes difficult to handle.

  According to the present embodiment, the signal cable 6 connected to the connection terminal 34 of the convex portion 38 is disposed so as to extend along the back surface 32 of the display panel 3 in the direction in which the fixing portion 331 is present (side surface 353 side). Is done. Thereby, the area occupied by the signal cable 6 when the display panel 3 is rotated can be reduced and the signal cable 6 can be easily handled. Moreover, since the insertion / extraction direction of the signal cable 6 with respect to the connection terminal 34 is substantially parallel to the back surface 32, the occupied area in the thickness direction of the display panel 3 can be reduced. In addition, since the signal cable 6 has a gradient 36 with respect to the back surface 32 so that the signal cable 6 extends away from the raised portion 321, interference between the raised portion 321 and the signal cable 6 is avoided.

  Further, since the fixing portion 331 overlaps the display portion 31 when viewed from the direction perpendicular to the display portion 31, the length of the display panel 3 in the longitudinal direction can be shortened. From this point of view, a configuration in which at least a part of the fixing portion 331 overlaps with the display portion 31 may be employed.

  Further, since the distance L1 is substantially equal to the distance L2 (FIG. 29B), the lower end position of the display panel 3 can be brought close to the upper end position of the handle 4 at the second photographing position (FIG. 30), and the imaging system is moved up and down. Can be compact in direction.

  Further, the user can shift the display panel 3 to the side (first photographing position) and the upper side (second photographing position) of the main unit 100 by rotating the display panel 3 around the rotation shaft 511a. As a result, the rotation operation is simple and simple.

  Moreover, since the convex part 38, the signal cable 6, and the element 391 overlap when seen from the direction perpendicular to the display part 31, the body can be made difficult to touch the high heat part. From this point of view, at least a part of the high temperature region and any one of the convex portion 38, the flexible portion 61 of the signal cable 6, and the grip portion 62 of the signal cable 6 face the display portion 31. What is necessary is just to make it the structure which overlaps by the projection of a straight direction. Further, the main heat generating portion is not limited to the element 391 for processing signals.

  Note that the hinge unit 5 has a configuration having at least one rotation shaft as long as the effect of reducing the occupied area of the signal cable 6 when the display panel 3 is rotated and making the signal cable 6 easy to handle is obtained. If it is.

  Note that a part or all of the above-described imaging system configured symmetrically may be used as the imaging system of the present invention. For example, the display panel 3 is positioned on the left side of the handle 4 of the main unit 100 at the first photographing position and the first storage position, but may be configured on the right side.

  The handle 4 is not essential for the main unit 100. Therefore, the hinge unit 5 may be connectable to the apparatus main body 2. In addition, as an example of an accessory group, this invention is applicable not only to the display panel 3, but accessories also with the temperature rise of an exterior cover at the time of use of a lighting unit etc.
