  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1A is a diagram of a digital camera which is a first embodiment of an imaging apparatus according to the present invention as viewed from the front side (subject side), and FIG. 1B is an upper surface of the digital camera shown in FIG. FIG.

  As shown in FIG. 1, the digital camera 1 of the present embodiment is provided with a lens barrel 9, a strobe light emitting unit 12, and the like on the front side of the camera body 2, and a mode switching dial 6 on the upper surface of the camera body 2. A release button 7, a zoom lever 11, a power button 8, and the like are provided. A display unit 3 having a display monitor 10 such as a liquid crystal is disposed on the back side of the camera body 2.

  The display unit 3 is supported so as to be rotatable in the opening / closing direction with respect to the camera body 2 via a hinge part 4 provided on the right side when the camera body 2 is viewed from the front side. In the present embodiment, the display unit 3 functions as a lid that covers and protects a suction device 30 (see FIG. 2B), which will be described later, provided in the center of the back surface of the camera body 2 in the closed state. On the upper surface of the camera body 2, an index 20 indicating the suction position is provided. Here, the camera body 2 corresponds to an example of the apparatus body of the present invention.

  2A is a diagram showing a state in which the display unit 3 of the digital camera 1 shown in FIG. 1A is opened, and FIG. 2B is a top view of FIG. FIG. 3 is a rear view of FIG. In addition, in FIG.2 (b), the adsorption | suction apparatus 30 is shown with sectional drawing.

  First, referring to FIG. 3, the contact portion 3 a provided on the display unit 3 is brought into contact with the back surface portion of the camera body 2 in the closed state of the display unit 3 to restrict the rotation of the display unit 3. A contact portion 2a is provided. In addition, a lock hole 2 b and an open / close detection sensor 5 for detecting the open / closed state of the display unit 3 are provided on the back surface of the camera body 2. The open / close detection sensor 5 is composed of, for example, a pressure-sensitive sensor, and detects the open / closed state of the display unit 3 by detecting the contact state between the contact portion 2a and the contact portion 3a.

  On the other hand, the display unit 3 is provided with a lock pin 3b, a slide portion 3c, and a storage recess 3d in addition to the contact portion 3a described above. The lock pin 3b is slidably provided along the slide part 3c. When the display unit 3 is closed, the lock pin 3 b is slid in the direction of arrow P in FIG. 3 to engage with the lock hole 2 b of the camera body 2, whereby the display unit 3 is locked with respect to the camera body 2.

  Conversely, when the lock pin 3b is slid in the arrow Q direction in FIG. 3 while the display unit 3 is locked, the engagement between the lock pin 3b and the lock hole 2b is released, and the display unit 3 is locked to the camera body 2. The display unit 3 can be opened and closed by being released. Further, the suction unit 30 provided in the center of the back surface of the camera body 2 with the display unit 3 closed is stored in the storage recess 3d.

  Next, the adsorption device 30 will be described. The adsorbing device 30 is configured to be adsorbable on a curved surface (cylindrical surface) such as a utility pole or a sign pole, and as shown in FIGS. 33, the 1st buffer member 32, and the adsorption | suction raw material 31 are laminated | stacked in order.

  The base material 34 is formed of, for example, a hard engineered plastic material, and supports the adsorption material 31, the first buffer member 32, and the second buffer member. The base material 34 may be formed integrally with the exterior of the back surface of the camera body 2 or may be formed separately from the camera body 2 and fixed to the back surface of the camera body 2 by bonding or the like.

  The adsorbing material 31 is disposed on the most surface side of the adsorbing device 30 and is formed of a flexible gel-like material having adhesiveness. The adsorbing material 31 adsorbs by adhering to the surface to be adsorbed without any gap using its flexibility. As such a gel material, for example, a synthetic resin-based gel such as a polyethylene-based material or a styrene-based material can be used. The first buffer member 32 and the second buffer member 33 are made of, for example, polyether-based or polyester-based urethane foam.

  Here, the base material 34 and the suction material 31 are both formed in a rectangular shape that is long in the width direction of the camera body 2 (the left-right direction in the figure), and the suction material 31 is used to secure a suction area on a flat surface. One buffer member 32 is covered over the entire region of the base material 34.

  On the other hand, the first buffer member 32 is elastically deformed when the camera body 2 is fixed to a power pole or the like via the suction device 30, and thereby the suction material 31 is deformed along the cylindrical surface of the power pole to become a power pole. Adsorption is fixed. For this reason, the elastic modulus E2 of the first buffer member 32 is set to be smaller than the elastic modulus E1 of the adsorption material 31.

  Similarly, the second buffer member 33 is elastically deformed together with the first buffer member 32 when the camera 1 is fixed to a pole or the like having a smaller diameter than the utility pole via the suction device 30, and thereby the suction material. 31 is fixed to the pole while being deformed along the cylindrical surface of the pole. Therefore, the elastic modulus E3 of the second buffer member 33 is set to be substantially equal to or smaller than the elastic modulus E2 of the first buffer member 32.

  Further, the area of the adsorbing material 31, the first buffer member 32, and the second buffer member 33 is such that the area of the adsorbing material 31 is larger than the area S1 of the adsorbing material 31 so that it can be adsorbed satisfactorily with respect to a flat surface or a cylindrical surface having a different curvature. The area S2 of the first buffer member 32 is larger than the area S3 of the second buffer member 33. The second buffer member 33 is fitted into a recess 34 a formed in the base material 34, and the first buffer member 32 is fitted into a recess 34 b formed in the base material 34. The recess 34 a is formed on the bottom surface of the recess 34 b, and the surface of the first buffer member 32 fitted in the recess 34 b is substantially flush with the surface of the base material 34.

  FIG. 4A is a diagram illustrating a state in which the camera 1 is sucked and fixed to the utility pole 50 via the sucking device 30. In addition, in Fig.4 (a), the adsorption | suction apparatus 30 and the utility pole 50 are shown with sectional drawing. Further, the display unit 3 is in a fully open state (approximately 180 °) with respect to the camera body 2.

  When fixing the camera 1 to the utility pole 50 via the suction device 30, the user attaches the camera body 2 to the suction device 30 with reference to the index 20 indicating the suction position provided on the upper surface of the camera body 2. And press against the utility pole 50.

  Here, the index 20 is arranged at the barycentric position of the camera 1 in the x direction in the figure with the display unit 3 opened with respect to the camera body 2. Further, in the present embodiment, the position of the index 20 substantially coincides with the center position of the second buffer member 33 of the suction device 30 in the x direction in the drawing.

  Thus, when the camera body 2 is fixed to a cylindrical surface such as a utility pole, a rotation moment in the xy plane in the figure is not generated, and a reduction in the suction force due to the rotation moment is prevented. The x direction in the figure is the width direction of the camera 1 (left and right direction in FIG. 1A), the y direction is the height direction of the camera 1 (up and down direction in FIG. 1A), and the z direction is the camera. 1 corresponds to the thickness direction of 1 (the front-rear direction in FIG. 1A).

  Further, the width w1 of the first buffer member 32 (see FIG. 3) in the same direction as the thickness t1 of the first buffer member 32 (see FIG. 2B) and the long side direction (x direction in the drawing) of the adsorption material 31. The ratio t1 / w1 to the reference) is preferably 0.1 ≧ t1 / w1 ≧ 0.05.

  Thereby, the first buffer member 32 can be more easily elastically deformed along the cylindrical surface of the utility pole 50 without increasing the thickness of the camera 1 in the z direction in the drawing. As a result, the adsorbing material 31 is deformed along the cylindrical surface of the electric pole 50 having a large curvature and is adsorbed over a wide area, thereby ensuring a good adsorbing force.

  FIG. 4B is a diagram illustrating a state in which the camera 1 is sucked and fixed to a pole 51 such as a road sign via the suction device 30. In addition, in FIG.4 (b), the adsorption | suction apparatus 30 and the pole 51 are shown with sectional drawing. Further, the display unit 3 is in a fully open state (approximately 180 °) with respect to the camera body 2.

  When the camera 1 is fixed to a pole 51 such as a road sign via the suction device 30, the user can use the index 20 indicating the suction position provided on the upper surface of the camera body 2 as a reference, as described above. The camera body 2 is pressed against the pole 51 through the suction device 30.

  Here, the thickness w2 (see FIG. 2B) of the second buffer member 33 in the same direction as the thickness t2 (see FIG. 2B) of the second buffer member 33 and the long side direction (x direction in the drawing) of the adsorption material 31. 3), the ratio t2 / w2 is preferably 0.2 ≧ t2 / w2 ≧ 0.075.

  Accordingly, the second buffer member 33 can be more easily deformed along the cylindrical surface of the pole 51 such as a road sign without increasing the thickness of the camera 1 in the z direction in the drawing. As a result, the adsorbing material 31 is deformed along the cylindrical surface of the pole 51 having a small curvature and adsorbed over a wide area, so that a good adsorbing force can be ensured.

  As described above, in the present embodiment, the adsorption material 31 can be attached to the pole 50 such as the electric pole 50 or the sign without using an urging means such as a coil spring arranged in the vertical direction with respect to the adsorption surface as in the prior art. It can be deformed along 51 and adsorbed over a wide area. Thereby, the digital camera 1 can be stably adsorbed to the curved surfaces such as the utility pole 50 and the sign pole 51 without impairing the portability of the digital camera 1 including the adsorption device 30.

(Second Embodiment)
Next, a digital camera which is a second embodiment of the imaging apparatus of the present invention will be described with reference to FIGS. Note that portions that overlap or correspond to the first embodiment will be described with the same reference numerals attached to the respective drawings.

  FIG. 5A is a diagram showing a state in which the lid unit 3A of the digital camera 1A of the present embodiment is opened, and FIG. 5B is a top view of FIG. 5A. FIG. 6 is a rear view of FIG. In addition, in FIG.5 (b), the adsorption | suction apparatus 30 is shown with sectional drawing.

  As shown in FIG. 5, in the digital camera 1A of the present embodiment, a display monitor 10 such as a liquid crystal is provided on the front side of the camera body 2A, and a mode switching dial 6 and a release are provided on the lower surface of the camera body 2A. Button 7 etc. are provided. A suction device 30 is provided in the center of the back side of the camera body 2A. In addition, on the upper surface of the camera body 2A, indicators 20 and 21 indicating the suction position are provided.

  On the back side of the camera body 2A, a lid unit 3A that covers and protects the suction device 30 (see FIG. 2B) in a closed state is provided. The lid unit 3A is supported so as to be rotatable in the opening / closing direction with respect to the rear surface portion of the camera body 2A via a hinge portion 4 provided on the right side when the camera body 2A is viewed from the front side.

  Further, a rotation axis 40 parallel to the x-axis in the figure is provided on the right side when the camera body 2A is viewed from the front side, and the lens barrel 9 rotates around the rotation axis 40 on the rotation axis 40. Connected as possible. The lens portion 41 provided in the lens barrel 9 is rotatable with respect to the lens barrel 9 about an axis parallel to the y-axis in the figure. As a result, the digital camera 1A of the present embodiment can be photographed through the glass by being adsorbed on a transparent wall such as glass.

  The contact portion 2a, the lock hole 2b, and the open / close detection sensor 5 provided in the camera body 2A are the same as those provided in the camera body 2 of the first embodiment. Further, the contact portion 3a, the lock pin 3b, the slide portion 3c, and the housing recess 3d provided in the lid unit 3A are the same as those provided in the display unit 3 of the first embodiment. In the housing recess 3d, the suction device 30A provided in the center of the back surface of the camera body 2A with the lid unit 3A closed is housed.

  Next, the adsorption device 30A will be described. The adsorbing device 30A is configured to be adsorbable on a curved surface (cylindrical surface) such as a utility pole or a sign pole, and as shown in FIGS. 33, the 1st buffer member 32, and the adsorption | suction raw material 31 are laminated | stacked in order.

  The base material 34 and the suction material 31 are both formed in a rectangular shape that is long in the width direction (left-right direction in the figure) of the camera body 2A, and the suction material 31 has a first buffer to secure a suction area on a flat surface. It is disposed over the entire area of the base material 34 while covering the member 32.

  On the other hand, the first buffer member 32 is elastically deformed when the camera body 2 is fixed to a power pole or the like via the suction device 30, and thereby the suction material 31 is deformed along the cylindrical surface of the power pole to become a power pole. Adsorption is fixed. For this reason, the elastic modulus E2 of the first buffer member 32 is set to be smaller than the elastic modulus E1 of the adsorption material 31.

  Similarly, the second buffer member 33 is elastically deformed together with the first buffer member 32 when the camera 1A is fixed to a pole or the like having a smaller diameter than the utility pole through the suction device 30. Thereby, the adsorbing material 31 is adsorbed and fixed to the pole while being deformed along the cylindrical surface of the pole. Therefore, the elastic modulus E3 of the second buffer member 33 is set to be substantially equal to or smaller than the elastic modulus E2 of the first buffer member 32.

  Further, the area of the adsorbing material 31, the first buffer member 32, and the second buffer member 33 is such that the area of the adsorbing material 31 is larger than the area S1 of the adsorbing material 31 so that it can be adsorbed satisfactorily with respect to a flat surface or a cylindrical surface having a different curvature. The area S2 of the first buffer member 32 is larger than the area S3 of the second buffer member 33.

  FIG. 7A is a diagram illustrating a state in which the camera 1A is suctioned and fixed to the utility pole 50 via the suction device 30A. In addition, in Fig.7 (a), 30 A of adsorption | suction apparatuses and the utility pole 50 are shown with sectional drawing. The lid unit 3A is in a fully open state (approximately 180 °) with respect to the camera body 2A.

  When fixing the camera body 2A to the utility pole 50 via the suction device 30A, the user uses the camera body 2A as the suction device 30A with reference to the index 20 indicating the suction position provided on the upper surface of the camera body 2A. And press against the utility pole 50.

  Here, the index 20 is disposed at a position that is substantially the center in the x direction in the drawing of the adsorption device 30A. Thereby, when the camera 1A is attracted to a cylindrical surface such as a power pole having a large curvature, a sufficient adsorption area can be secured.

  Further, the thickness w1 of the first buffer member 32 (see FIG. 6) in the same direction as the thickness t1 of the first buffer member 32 (see FIG. 5B) and the long side direction (x direction in the drawing) of the adsorption material 31. The ratio t1 / w1 to the reference) is preferably 0.1 ≧ t1 / w1 ≧ 0.05.

  Thereby, the first buffer member 32 can be more easily elastically deformed along the cylindrical surface of the utility pole 50 without increasing the thickness of the camera 1A in the z direction in the drawing. As a result, the adsorbing material 31 is deformed along the cylindrical surface of the electric pole 50 having a large curvature and is adsorbed over a wide area, thereby ensuring a good adsorbing force.

  FIG. 7B is a diagram illustrating a state in which the camera 1A is sucked and fixed to a pole 51 such as a road sign via the suction device 30A. In addition, in FIG.7 (b), the adsorption | suction apparatus 30A and the pole 51 are shown with sectional drawing. The lid unit 3A is in a fully open state (approximately 180 °) with respect to the camera body 2A.

  When fixing the camera body 2A to the pole 51 such as a road sign via the suction device 30A, the user uses the index 21 indicating the suction position provided on the upper surface of the camera body 2A as a reference, as described above. The camera body 2A is pressed against the pole 51 through the suction device 30A.

  Here, the index 21 is arranged at the center of gravity of the camera 1A in the x direction in the figure in a state where the lid unit 3A is opened with respect to the camera body 2A. In the present embodiment, the position of the index 21 is spaced from the index 20 on the hinge part 4 side and is substantially the same as the center position in the x direction of the second buffer member 33 of the suction device 30A. I'm doing it.

  As a result, when the camera body 2A is attracted and fixed to the cylindrical surface of a pole such as a sign having a small curvature, a rotation moment in the xy plane in the figure is not generated, and a decrease in the adsorption force due to the rotation moment is prevented. ing.

  Further, the width w2 of the second buffer member 33 (see FIG. 6) in the same direction as the thickness t2 of the second buffer member 33 (see FIG. 5B) and the long side direction (x direction in the drawing) of the adsorption material 31. The ratio t2 / w2 with respect to the reference) is preferably 0.2 ≧ t2 / w2 ≧ 0.075.

  Accordingly, the second buffer member 33 can be more easily deformed along the cylindrical surface of the pole 51 such as a road sign without increasing the thickness of the camera 1A in the z direction in the drawing. As a result, the adsorbing material 31 is deformed along the cylindrical surface of the pole 51 having a small curvature and adsorbed over a wide area, so that a good adsorbing force can be ensured. Other configurations and operational effects are the same as those in the first embodiment.
