Next, the operation of connecting and separating the photographing display unit 100 and the handheld unit 200 will be described.

As shown in FIG. 4A, the second coupling portion 210 is composed of a second rail 211, a second support surface 212, a second lever 213, and a second claw 214.

First, when connecting the photographing display unit 100 and the hand-held portion 200, the photographing display unit 100 is carried above the hand-held portion 200, and the first rail 131 is arranged above the second rail 211. Then, the position of the photographing display unit 100 is lowered while pressing the first rail 131 against the second coupling unit 210 side. Then, the first rail 131 and the second rail 211 mesh with each other. The second claw 214 is itself an elastic member, or is supported so as to be elastically deformable by receiving an elastic force from another elastic member. When the photographing display unit 100 is further lowered while the first rail 131 and the second rail 211 are in mesh with each other, the second claw 214 is pushed away by the first coupling portion 130 toward the second elastic member 230. When the photographing display unit 100 is further lowered while the second claw 214 is pushed away, the first support surface 132 and the second support surface 212 come into contact with each other. When abutted, the pushed-out second claw 214 enters the space above the first claw hooking portion 133 by the restoring force. On the other hand, the second claw 214 and the first claw hooking portion 133 are provided with an inclination in a direction in which they mesh with each other. When combined, the photographing display unit 100 and the hand-held unit 200 are firmly positioned by the engagement of the first rail 131 and the second rail 211, and the second claw 214 and the first claw hooking portion 133. With the above operation, the shooting display unit 100 and the handheld unit 200 can be combined.

Next, a case where the photographing display unit 100 and the handheld unit 200 are separated will be described. When separating, the second lever 213 is used. When the second lever 213 is moved toward the second elastic member 230 with a user's finger or the like, the second claw 214 comes out of the space above the first claw hooking portion 133. In this state, when the photographing display unit 100 is moved upward to the hand-held portion 200, the second claw 214 and the first claw hooking portion 133 do not get caught. Therefore, the photographing display unit 100 moves upward while being guided by the first rail 131 and the second rail 211. If the movement is continued, the first rail 131 and the second rail 211 are separated. By the above operation, the shooting display unit 100 and the handheld unit 200 can be separated.

Next, details such as the position and function of the button 160 will be described. As described above, the button 160 is an operation unit arranged at the position shown in FIG. 3A on the shooting display unit 100. Therefore, in the hand-held mode described with reference to FIG. 1, the button 160 is located in the vicinity of the grip portion 220 of the hand-held portion 200. Since the button 160 is located in the vicinity of the grip portion 220, the user can touch the button 160 with the index finger while holding the grip portion 220 as shown in FIG. As a result, the user can operate the button 160 while looking into the display unit 110 without releasing both hands from the grip portion 220. Since the buttons can be operated without releasing both hands, it is unlikely that the handling will be accidentally dropped. Further, when the button is operated, it is unlikely that the finger crosses the front of the front cover 140 of the shooting display unit 100 and the finger is reflected in the shot image. In the above description, the case where there is only one button 160 has been described, but for example, a plurality of buttons may be arranged in the vicinity of the position shown in FIG. 3A. Further, the user may operate the button 160 without looking at the button 160 while looking into the display unit 110. It is desirable that the button 160 has a shape such as unevenness so that the presence of the button 160 can be detected only by the user touching the button 160. Further, the button 160 may be a button other than the push button. Depending on the function, a latch switch, a slide switch, a stick, a touch panel, etc. may be appropriately selected and arranged.

Various functions can be assigned to the button 160. The first function is to turn on / off the power of the shooting display unit 100. For example, when the power of the shooting display unit 100 is turned off, the button 160 may be pressed or pressed for several seconds to turn it on. Alternatively, when the power of the shooting display unit 100 is turned on, the button 160 may be pressed, or the button 160 may be pressed for several seconds to turn it off. The second function is to switch the display unit 110 on and off.

For example, in order to save power, it is desirable to turn off the display device of the display unit 110 frequently. Therefore, the function of turning on the display device of the display unit 110 may be provided only when the button 160 is pressed. If the user presses the button 160 to light the display unit 110 only when viewing the display unit 110, the lighting time can be reduced. If it is troublesome to operate the button 160 each time, the display unit 110 may be automatically turned off at a predetermined time. In this case, the button 160 is used only when the display unit 110 is switched from turning off to turning on. The third function is to change the internal parameters of the shooting display unit 100. The internal parameters are parameters that determine the brightness, contrast, aperture, sensitivity, focus, and the like of the display unit 110. In addition, whether or not to superimpose a virtual object or landscape on the real landscape is also a kind of internal parameter. For example, when the button 160 is pressed, the GUI is displayed on the display unit 110. The user may be able to change the above-mentioned internal parameters by combining a plurality of button operations while looking at the GUI.
