<Mechanical operation of camera 1>
The movable monitor 20 having the above support structure operates as follows with respect to the camera body 10. FIG. 1 shows an initial position (stored state) in which the entire movable monitor 20 is housed in the monitor housing portion 30 of the camera body 10. At the initial position, the two positioning protrusions 32 are inserted into the through holes 23a to fix the position of the movable monitor 20. The base plate 23 is attracted by the magnetic force of the magnet provided in each positioning protrusion 32 to hold the movable monitor 20 at the initial position. Further, along the upper edge wall 30a, the lower edge wall 30b, the left edge wall 30c, and the right edge wall 30d that surround the monitor housing portion 30, the upper side portion 22a, the lower side portion 22b (flange 23b), and the left side portion 22c on the movable monitor 20 side are provided. The (flange 23c) and the right side portion 22d (flange 23d) are located. At the initial position of the movable monitor 20, the spherical end 25 of each support rod 24 is located near the outer end of the guide groove 31, and the rising angle (projection amount) of each support rod 24 with respect to the monitor housing 30 is minimum. It has become. At the initial position of the movable monitor 20, the four sockets 27 and the spherical ends 26 of the four support rods 24 are in a positional relationship surrounding the virtual line O′. The orientation of the movable monitor 20 at the initial position is set so that the display screen 21a of the display device 21 is substantially orthogonal to the optical axis O (more precisely, a virtual line O'extending the optical axis O to the rear). ing. The direction of the movable monitor 20 is used as a reference angle.

As shown in FIGS. 2 to 5, the movable monitor 20 can be tilted from the reference angle at the initial position in the four directions of up, down, left and right (longitudinal longitudinal direction and lateral short direction of the display screen 21a). FIG. 3 shows a state in which the movable monitor 20 is tilted leftward about an axis extending in the vertical direction. The tilting of the movable monitor 20 to the left is performed by pulling the right side portion 22d (flange 23d) toward the rear, with the contact point between the left side portion 22c (flange 23c) and the left edge wall 30c as a fulcrum. At this time, the two support rods 24 on the upper right side and the lower right side respectively move the spherical end portion 25 from the vicinity of the outer end portion of the guide groove 31 toward the inner end portion side and rise angle (projection) with respect to the monitor accommodating portion 30. Amount) is increased, and as a result, the two sockets 27 on the upper right side and the lower right side are pushed rearward, whereby the movable monitor 20 tilts leftward. FIG. 3 shows a state in which the movable monitor 20 is operated up to the maximum leftward tilt angle by pushing out the two support rods 24 on the upper right side and the lower right side. In this state, the two spherical shapes on the upper right side and the lower right side are shown. The end 25 is located near the inner end of the corresponding guide groove 31.

FIG. 4 shows a state in which the movable monitor 20 is tilted downward with the axis extending in the left-right direction as the center. The tilting of the movable monitor 20 to the lower side is performed with the contact point between the lower side portion 22b (flange 23b) and the lower edge wall 30b as a fulcrum by pulling the upper side portion 22a side backward. At this time, the two support rods 24 on the upper left side and the upper right side respectively move the spherical end portion 25 from the vicinity of the outer end portion of the guide groove 31 toward the inner end portion side, and the rising angle (projection amount) with respect to the monitor housing portion 30. ) Is increased, and as a result, the two sockets 27 on the upper left side and the upper right side are pushed backward, so that the movable monitor 20 tilts downward. FIG. 4 shows a state in which the movable monitor 20 is operated up to the maximum downward tilt angle by pushing out the two support rods 24 on the upper left side and the upper right side, and in this state, the two spherical ends on the upper left side and the upper right side. 25 is located near the inner end of the corresponding guide groove 31.

At the initial position of the movable monitor 20 of FIG. 1 (the state of being housed in the monitor housing portion 30), the movable monitor is moved by the upper edge wall 30a, the lower edge wall 30b, the left edge wall 30c, and the right edge wall 30d around the monitor housing portion 30. By surrounding 20, it is possible to prevent the movable monitor 20 from being inadvertently operated by preventing external catches and the like. The low wall 30i formed at the upper end portion (boundary portion with the upper edge wall 30a) of the right edge wall 30d includes an operation dial 50 located on the upper right of the movable monitor 20 and a plurality of operation buttons located below the operation dial 50. It has a function of improving the operability of 51. Specifically, when the grip portion of the camera body 10 is held by the right hand, the operation dial 50 and the push buttons (a part of the plurality of operation buttons 51) located around the operation dial 50 are assumed to be operated by the right thumb. It At that time, since the low wall 30i is positioned on the movement path of the thumb, the thumb can reach the operation dial 50 smoothly without being caught by the high walls (30a, 30b, 30c and 30d) surrounding the monitor housing 30. It is easy to make.

As described above, at the initial position of the movable monitor 20, the movable monitor 20 can be protected by the walls 30a, 30b, 30c and 30d (including the low wall 30i) provided at the positions surrounding the four corners of the movable monitor 20 in the upper, lower, left and right directions. On the other hand, by forming recesses 30e, 30f, 30g, and 30h around the monitor housing portion 30, the edge of the movable monitor 20 is partially exposed, and the movable monitor 20 can be moved from the initial position as shown in FIGS. Good operability (finger grabbing) when the monitor 20 is tilted is also realized. Since all of the recesses 30e, 30f, 30g, and 30h are formed corresponding to the central portions of the upper side portion 22a, the lower side portion 22b, the left side portion 22c, and the right side portion 22d of the movable monitor 20, the recesses 30e, 30f, 30g, and 30h are formed in the vertical and horizontal directions from the initial position. A force for tilting the movable monitor 20 can be easily applied.

2 to 5 show the state in which the movable monitor 20 is tilted to the maximum tilt angle in the vertical and horizontal directions by pushing out the support rod 24, but in the middle between the inner end portion and the outer end portion of the guide groove 31. By positioning the spherical end 25, it is possible to hold the movable monitor 20 at an arbitrary tilt angle smaller than this. The spherical ends 25 of the support rods 24 are fitted in the corresponding guide grooves 31 with a predetermined friction, and when the tilting operation of the movable monitor 20 is stopped halfway, the movable monitor 20 is rotated at that angle. Can be held. The maximum tilt angle of the movable monitor 20 can be made larger or smaller than the size shown in FIGS. 2 to 5 by changing the setting of the length of the support rod 24 and the length of the guide groove 31. ..

As shown in FIG. 5, the movable monitor 20 can further rotate the support frame 22 with respect to the tilt plate 22x with respect to the base plate 23 to increase the upward angle. For example, when the movable monitor 20 as a whole is turned up about 40 degrees with respect to the camera body 10 by the tilting (first step tilting) via the support rod 24 described above, the support frame 22 tilts (two steps) with respect to the base plate 23. The tilt of the eyes) causes the support frame 22 and the display device 21 to change upward by about 90 degrees with respect to the initial position in FIG. 1 (see FIG. 5 ). Thereby, for example, the movable monitor 20 can be used like a waist level finder. The rotation of the support frame 22 can be performed by placing a finger on a portion of the support frame 22 which is not covered by the flanges 23b, 23c and 23d of the base plate 23.

When the movable monitor 20 is close to the camera body 10 and is housed in the monitor housing 30 (initial position), the movable monitor 20 can be tilted about an axis in a specific direction such as the vertical direction or the horizontal direction as described above. it can. The tilting of the movable monitor 20 is referred to as the tilting of the first aspect. In addition to the tilting of the first mode, the movable monitor 20 is pulled out from the monitor housing portion 30 rearward in the optical axis direction (direction along a virtual line O′ extending the optical axis O), as shown in FIGS. 2 and 6. Can be separated from the camera body 10. The operation of pulling out the movable monitor 20 is performed by increasing the rising angles (protrusion amounts) of the four support rods 24 with respect to the monitor housing portion 30. For example, by making the protrusion amounts of the four support rods 24 with respect to the monitor accommodating section 30 substantially equal, the movable monitor 20 is not tilted (while maintaining the reference angle) from the initial position of FIG. Can be moved substantially parallel to the state of FIG. 2 or FIG.

In a state where the movable monitor 20 is pulled out to the rear of the monitor housing portion 30 and is separated from the camera body 10, the movable monitor 20 includes the upper edge wall 30a, the lower edge wall 30b, the left edge wall 30c, and the right edge wall of the monitor housing portion 30. It becomes possible to operate without being restricted by 30d. Therefore, as shown in FIGS. 3 to 5, it is possible to tilt in any direction without being limited to the axis center of a specific direction such as the vertical direction and the horizontal direction. For example, although not shown, the movable monitor 20 can be tilted in a direction such as diagonally right up, diagonally left down, diagonally left up, and diagonally right down, and its angle is also arbitrarily set within a range in which each support rod 24 can follow. Can be set. The tilting of the movable monitor 20 in any direction is referred to as the tilting of the second aspect. In the tilting of the second aspect, the movable monitor 20 can be tilted in the vertical and horizontal directions (longitudinal direction and lateral direction of the display screen) similarly to the tilting of the first aspect. Further, when the movable monitor 20 is pulled out rearward by less than the maximum amount, the movable monitor 20 in the direction orthogonal to the optical axis O is maintained within a predetermined range in which each support rod 24 can follow, while maintaining the reference angle. You can also move.

In a state in which the movable monitor 20 is pulled out to the rear of the monitor housing portion 30, a virtual line O′ (extending direction of the movable monitor 20 with respect to the camera body 10 with respect to the camera body 10 is further extended within a range in which each support rod 24 can follow. It is also possible to rotate the movable monitor 20 about an axis that points toward. In addition, in the present embodiment, since the outer shape center of the movable monitor 20 in the stored state is located substantially on the virtual line O′ extending the optical axis O, the movable monitor 20 in the state of FIG. Although it is rotatable about the center, it is also possible that the virtual line O′ extending the optical axis O passes through a position different from the outer center of the movable monitor 20. In this case, the positions of the outer shape center and the rotation center of the movable monitor 20 do not match.

<Functional configuration of camera 1>
FIG. 8 is a functional block diagram showing the main configuration of the control system of the camera 1 of the first embodiment. In FIG. 8, a configuration particularly related to lighting control is shown. In FIG. 8, the camera 1 has an operation unit 71, a control unit 72, an illumination unit 73, and a display device 21.

The operation unit 71 receives various operations by the user and outputs an operation notification signal corresponding to the operation to the control unit 72. The types of the operation notification signals include, for example, an operation notification signal for setting the lighting unit 73 in the lighting mode, an operation notification signal for setting the lighting unit 73 in the off mode, an operation notification signal for instructing lighting of the lighting unit 73, and An operation notification signal or the like for instructing turning off of the illumination unit 73 can be given. The operation unit 71 includes the operation dial 50, the operation button 51, the operation button 52, and the operation switch 53 described above. The operation switch 53 outputs an operation notification signal instructing to turn on the illumination unit 73 when pressed in the initial state, and outputs an operation notification signal instructing to turn off the illumination unit 73 when pressed next time.

The control unit 72 controls, for example, various setting processing, display processing, and lighting processing. The control unit 72 includes a setting control unit 72A, a display control unit 72B, and an illumination control unit 72C. The control unit 72 is realized by, for example, the circuit board 17 and the circuit board 60.

For example, when the user performs a menu display operation using the operation unit 71, the operation unit 71 outputs an operation notification signal instructing the menu display to the control unit 72. When the display control unit 72B of the control unit 72 receives the operation notification signal for instructing the menu display, it causes the display device 21 to display the menu screen.

When the user makes a lighting setting using the operation unit 71 by looking at this menu screen display, the operation unit 71 outputs an operation notification signal indicating the lighting setting to the control unit 72. In the illumination setting, for example, the illumination unit 73 can be set to either the lighting mode or the extinction mode. Furthermore, in the illumination setting, the illuminance level when the illumination unit 73 is illuminated in the illumination mode can be set. The setting control unit 72A stores the latest various setting information.

Further, when the user performs an operation of instructing to turn on the illumination unit 73 using the operation switch 53 in the operation unit 71, the operation switch 53 causes the operation notification signal to instruct to turn on the illumination unit 73 as described above. Is output to the control unit 72. When the illumination control unit 72C of the control unit 72 receives the operation notification signal for instructing the lighting of the illumination unit 73, the illumination control unit 72C inquires of the setting control unit 72A about the setting mode of the illumination unit 73, and the setting mode of the illumination unit 73 is the lighting mode. In this case, the lighting command signal is output to the lighting unit 73 to turn on the lighting unit 73, and when the lighting unit 73 is in the off mode, the lighting unit 73 outputs the control signal without outputting any control signal. The off state of the unit 73 is continued.

When the operation switch 53 is used to instruct the lighting unit 73 to be turned off, the operation switch 53 outputs an operation notification signal to the control unit 72 to instruct the lighting unit 73 to be turned off, as described above. When the illumination control unit 72C of the control unit 72 receives the operation notification signal instructing to turn off the illumination unit 73, it outputs an extinction command signal to the illumination unit 73. Here, the illumination control unit 72C automatically outputs a turn-off command signal to the illumination unit 73 when the photographing process is started. As a result, it is possible to prevent the shooting quality from being adversely affected by the light of the illumination unit 73.

The illumination unit 73 includes the LED 61. The illumination unit 73 is turned on when receiving the lighting command signal from the lighting control unit 72C, and is turned off or continues to be in the unlit state when receiving the lighting command signal.

<Operation and effect of camera 1>
As described above, according to the present embodiment, in the camera 1, the illumination unit 73 (which illuminates the operation unit 71 (the operation dial 50, the operation button 51, the operation button 52, and the operation switch 53) provided in the camera body 10 ( The LED 61 and the illumination opening 62a) are provided on a movable monitor (movable body) 20 that is movably (movable in posture) supported by the camera body 10. The “posture deformation” is a relative positional relationship between the movable monitor (movable body) 20 and the camera body 10, and includes changes in separation distance and angle. Accordingly, the posture (position, inclination) of the movable monitor 20 can be adjusted, and the irradiation position of the camera body 10 irradiated by the illumination unit 73 can be changed according to the user's wish. Therefore, for example, the illumination target that the user desires to illuminate can be positively illuminated from among the operation dial 50, the operation button 51, the operation button 52, and the operation switch 53, so that the illumination target has sufficient brightness. It is possible to illuminate with, and as a result, operability can be improved. For example, if the posture of the movable monitor 20 is the posture shown in FIG. 3, the operation button 51 can be efficiently illuminated in this posture.

In particular, in the camera 1 of the present embodiment, the four illumination openings 62a forming the illumination unit 73 are respectively provided in the four corner areas of the front surface (first surface) of the movable monitor 20 facing the rear surface of the camera body 10. It is provided. Accordingly, the illumination openings 62a are dispersedly arranged on the front surface (first surface) of the movable monitor 20, so that a wide illumination range can be secured. However, the illuminating unit 73 (LED 61, the illumination opening 62a) is provided with a degree of freedom in the position where it is located so as to avoid at least the rear surface (the second surface opposite to the first surface) of the movable monitor 20. Good. Here, “a position avoiding the second surface” includes the first surface and the side surface of the movable monitor (plate-shaped member) 20 connecting the first surface and the second surface.

In addition, in the camera 1 of the present embodiment, the illumination opening 62a is provided on the front surface of the movable monitor (movable body) 20, while the display screen 21a is provided on the rear surface of the movable monitor 20. As a result, it is possible to operate the operation unit 71 illuminated by the light emitted from the illumination opening 62a while looking at the display screen 21a, so that the operability can be improved. However, as long as the illumination unit 73 is provided on the movable body, the posture (position, inclination) of the movable body can be adjusted and the irradiation location of the camera body 10 illuminated by the illumination unit 73 can be changed according to the user's request. You can

Further, since the camera 1 of the present embodiment has a high degree of freedom in setting the position of the movable monitor 20 with respect to the camera body 10, it illuminates the operation unit 71 (the operation dial 50, the operation button 51, the operation button 52, and the operation switch 53). The degree of freedom to adjust the condition is high. As a first mode of operation of the movable monitor 20, since the movable monitor 20 can be tilted in four directions of up, down, left, and right in a state in which the movable monitor 20 is in the initial position in the monitor housing portion 30, a direction in which the movable monitor 20 is tilted. It is possible to illuminate the operation unit 71 located in the opposite direction, that is, in the direction in which the surface on which the LED 61 is provided faces. As a second mode of operation of the movable monitor 20, in a state where the movable monitor 20 is moved backward from the initial position in the optical axis direction (a direction away from the camera body 10), free tilting without direction restriction is possible. Therefore, it becomes possible to directly direct the illumination light of the LED 61 to the operation unit 71 desired to be illuminated. The tilting of the movable monitor 20 in the second mode is different from the tilting of the first mode in that the display screen 21a of the display device 21 of the movable monitor 20 does not pass through a reference angle that is substantially orthogonal to the optical axis O. Since it is possible to directly shift from the tilt direction to the next tilt direction, operability is excellent.

«Second embodiment»
The second embodiment relates to a variation of lighting control. The mechanical configuration of the camera 1'of the second embodiment is common to that of the camera 1 of the first embodiment shown in FIGS.

FIG. 9 is a functional block diagram showing the main configuration of the control system of the camera 1'of the second embodiment. In FIG. 9, the camera 1 ′ has a control unit 72 ′ having an illumination control unit 72 ′C, a posture detection unit 75, and an illuminance sensor 76.

The posture detection unit 75 detects the posture of the movable monitor 20 with respect to the camera body 10, and the illumination control unit 72 ′C determines the illumination pattern of the lighting unit 73 according to the posture of the movable monitor 20 detected by the posture detection unit 75. To control.

There are various variations in the posture detection by the posture detection unit 75 and the illumination pattern control by the illumination control unit 72′C.

(Variation 1)
The posture detection unit 75, when the posture of the movable monitor 20 is changed from the initial position state to a state other than the initial position state, a posture notification signal indicating that the posture of the movable monitor 20 is changed to a state other than the initial position state. To the lighting control unit 72′C. The illumination control unit 72′C turns on the illumination unit 73 by using the reception of the posture notification signal indicating that the posture of the movable monitor 20 has been changed to a state other than the initial position state as a trigger. On the contrary, when the posture of the movable monitor 20 is changed from a state other than the initial position state to the initial position state, the posture detection unit 75 outputs a posture notification signal indicating that the posture of the movable monitor 20 is changed to the initial position state. To the lighting control unit 72′C. The illumination control unit 72′C turns off the illumination unit 73 with a trigger of receiving a posture notification signal indicating that the posture of the movable monitor 20 has been changed to the initial position state. According to the variation 1, the illumination unit 73 can be reliably turned off in the initial position state where the illumination unit 73 cannot illuminate the operation unit 71, and power saving of the camera 1′ is realized. Further, since the illumination unit 73 can be automatically turned on and off when the movable monitor 20 is in a state other than the initial position state and the initial position state, the operability of the illumination operation can be improved.

(Variation 2)
It is also possible to limit the control of the variation 1 according to the brightness of the surrounding environment sensed by the illuminance sensor 76.
For example, when the brightness level sensed by the illuminance sensor 76 is lower than the predetermined level (that is, when it can be determined that the brightness is dark), the illumination control unit 72′C allows the illumination pattern control of variation 1, while When the brightness level detected by the sensor 76 is equal to or higher than a predetermined level (that is, when it can be determined that the brightness is bright), a posture notification signal indicating that the posture of the movable monitor 20 is changed to a state other than the initial position state Even if it receives, the illumination unit 73 is not turned on. As a result, it is possible to avoid unnecessary lighting of the illumination unit 73, and thus further power saving of the camera 1′ is realized.
Here, for example, when the display control unit 72B adjusts (sets) the brightness level of the display device 21 according to the brightness of the surrounding environment sensed by the illuminance sensor 76, the illumination control unit 72′C The control of the illumination pattern may be linked to the adjustment (setting) of the brightness level of the display device 21. For example, the illumination control unit 72′C may execute the permission and the limitation of the illumination pattern control according to the brightness level of the display device 21.

(Variation 3)
According to the posture of the movable monitor 20 detected by the posture detection unit 75, among the four LEDs 61 provided in the four corner areas of the movable monitor 20, the LED 61 that is turned on and the LED 61 that is turned off are configured. It is also possible to control (illumination pattern).

For example, the posture detection unit 75 detects the position of the spherical end 25 in each guide groove 31, and outputs a position detection signal indicating the detected position of each spherical end 25 to the illumination control unit 72′C as a posture notification signal. To do. The illumination control unit 72′C specifies the spherical end 25 whose distance to the outer end of the guide groove 31 is equal to or less than a predetermined value, that is, the rising angle (protrusion amount) based on the posture notification signal, for example. ) Is greater than or equal to a predetermined value, the support rod 24 is specified. Then, the illumination control unit 72′C turns on the LEDs 61 that are arranged to face the specified spherical end 25 at the initial position of the movable monitor 20, while keeping the other LEDs 61 in the off state.

According to this control, for example, when the movable monitor 20 is in the posture shown in FIG. 3, only the upper right and lower right LEDs 61 that can efficiently illuminate the operation button 51 in this posture are turned on and turned on. Even if it is done, the upper left and lower left LEDs 61, which are mainly in the state of illuminating the inside of the monitor housing portion 30, can be maintained in the off state. The conical imaginary line shown in FIG. 3 schematically shows the irradiation range of the upper right and lower right LEDs 61.

Further, if the movable monitor 20 has the posture shown in FIG. 2, the illumination control unit 72′C turns on all four LEDs 61. The conical imaginary line shown in FIG. 2 schematically shows the irradiation range of each LED 61.

Further, if the attitude of the movable monitor 20 is the attitude shown in FIG. 4, it is assumed that only the upper right and upper left LEDs 61, which can efficiently illuminate the operation dial 50 and the operation button 52 in this attitude, are turned on and turned on. Also, the lower right and lower left LEDs 61, which are mainly in the state of illuminating the inside of the monitor housing section 30, can be maintained in the off state. The conical virtual line shown in FIG. 4 schematically shows the irradiation range of the LEDs 61 on the upper right and upper left.

Furthermore, if the light emission colors of the four LEDs 61 are made different, the color with which the operation unit 71 is illuminated can be changed according to the type of the operation unit 71. With this, the user can easily recognize the type of the operation unit 71 illuminated by the LED 61 by the color, and the convenience for the user can be improved.

Here, when the movable monitor 20 is in the posture shown in FIG. 5, that is, when the support frame 22 is rotated around the tilt shaft 22x with respect to the base plate 23, the irradiation direction of each LED 61 is downward. Becomes Therefore, in this posture, the LED 61 cannot efficiently illuminate the operation section 71. Therefore, when the posture detection unit 75 detects the posture of the movable monitor 20 shown in FIG. 5, the illumination control unit 72′C may perform control to turn off all the four LEDs 61. As a result, it is possible to avoid unnecessary lighting of the LED 61, so that power saving of the camera 1′ is realized.

(Variation 4)
Similar to the variation 2, the control of the variation 3 can be limited according to the brightness of the surrounding environment sensed by the illuminance sensor 76.

(Variation 5)
When each LED 61 is a module capable of emitting light of multiple colors such as red, blue, and green, the following illumination pattern control can be executed. For example, the illumination control unit 72′C may change the color emitted by the LED 61 according to the posture of the movable monitor 20 detected by the posture detection unit 75. For example, the color emitted by the LED 61 can be a color corresponding to the type of the operation unit 71 illuminated by the LED 61. With this, the user can easily recognize the type of the operation unit 71 illuminated by the LED 61 by the color, and the convenience for the user can be improved.

Further, it is possible to control the illumination according to both the setting mode and the attitude of the movable monitor 20 (the separated state of the movable monitor 20 from the camera body 10, the inclined state, etc.). For example, when the movable monitor 20 is tilted with respect to the camera body 10 and the setting mode is the shooting mode, the control of turning on the LED 61 may be executed for a predetermined time after the power is turned off.

(2) The lighting control described in the first embodiment can be controlled according to the operating state of the camera.
