Therefore, when the eyepiece 130 is not pulled out, that is, when the display unit 110 and the cover unit 140 are simply raised upward as shown in FIG. 8(c), the electronic viewfinder 10 displays images. preferably not. In this way, the eyepiece 130 is pulled out, and the electronic viewfinder 10 can be displayed only in a usable state. It is possible to prevent it from disappearing unpreparedly.

As shown in FIGS. 1(b) and 5(a), the proximity sensor window 14 is provided in the upper frame of the display device 20, and is interlocked with the rotation operation (tilt operation) of the display device 20. , the orientation of the proximity sensor window 14 changes. As described above, when the eyepiece 130 of the electronic viewfinder 10 is not pulled out, the proximity sensor 14a is not controlled, and the rotation of the display device 20 does not affect the proximity sensor 14a. However, if the display device 20 rotates when the eyepiece 130 of the electronic viewfinder 10 is pulled out, the direction of the proximity sensor window 14 changes, and the proximity sensor 14a detects the proximity of an object (object detection range) changes.

Next, a change in the object detection range 14b by the proximity sensor 14a due to the rotation of the display device 20 will be described with reference to FIG. FIG. 9 is a side view of the imaging device 1. FIG. FIG. 9A shows a state in which the display device 20 is rotated upward by 45°. FIG. 9B shows a state in which the display device 20 is rotated downward by 45°. FIG. 9(c) shows a state in which the display device 20 is rotated upward by 90°. FIG. 9(d) shows a state in which the display device 20 is rotated upward by 150°. FIG. 9, which explains changes in the object detection range 14b by the proximity sensor 14a, should originally show the usage state in which the eyepiece 130 of the electronic viewfinder 10 is pulled out. However, FIG. 9 shows a state in which the electronic viewfinder 10 is accommodated inside the imaging apparatus 1 in order to facilitate understanding of the attitude of the display device 20 and changes in the object detection range 14b by the proximity sensor 14a.

As shown in FIGS. 9A and 9B, when the display device 20 is rotated upward or downward by 45°, the rear side of the imaging device 1 falls within the object detection range 14b of the proximity sensor 14a. Therefore, it is possible to perform control to turn on the display of the electronic viewfinder 10 when the user brings the face close to the back surface of the imaging device 1 . On the other hand, as shown in FIGS. 9C and 9D, when the display device 20 is rotated upward by 90° or 150°, the rear surface of the imaging device 1 is positioned outside the object detection range 14b of the proximity sensor 14a. get off. Therefore, there is a possibility that the display of the electronic viewfinder 10 will not be turned on even if the user brings his or her face close to the back surface of the imaging device 1 . However, for example, when the display device 20 is rotated upward by 90° as shown in FIG. There is no problem because the possibility of shooting while looking into the camera is low. In addition, when the display device 20 is rotated upward by 150° as shown in FIG. No problem. However, in the state shown in FIG. 9D, the main body of the imaging device 1 enters the object detection range 14b of the proximity sensor 14a. is turned off, the display of the electronic viewfinder 10 may be turned on.

Next, referring to FIG. 10, a method for preventing erroneous detection by the proximity sensor 14a will be described. FIG. 10 is a side view of the imaging device 1. FIG. In FIG. 10, the electronic viewfinder 10 shows a usage state in which the eyepiece 130 is pulled out (a state in which the electronic viewfinder 10 (eyepiece 130) is at the usage position).

When the display device 20 is rotated upward by approximately 90° in the state shown in FIG. 10, that is, in a state in which the eyepiece 130 is pulled out, the main body of the image pickup device 1 becomes a proximity sensor as shown in FIG. 9C. The object has not entered the detection range 14b of the object 14a. Therefore, erroneous detection of the proximity sensor 14a does not occur. However, when the display device 20 is further rotated upward from this state, as shown in FIG. is falsely detected. In order to prevent this, in this embodiment, when the display device 20 is rotated upward by about 90° (rotated by a predetermined angle), the display device 20 is configured as shown in FIG. The cover 22 contacts the eyepiece 130 of the electronic viewfinder 10 . With such a configuration, even if an attempt to rotate the display device 20 further upward is blocked by the eyepiece portion 130 as a restricting portion, the display device 20 cannot be rotated further upward.

In this way, when the eyepiece portion 130 of the electronic viewfinder 10 is pulled out, the upward rotational motion beyond the display device 20 by about 90° is restricted. Therefore, the main body of the imaging device 1 does not enter the object detection range 14b of the proximity sensor 14a, and erroneous detection of the proximity sensor 14a does not occur. When the eyepiece 130 is pulled out, the display device 20 cannot be rotated up to 180° with respect to the main body of the imaging device 1 . However, since the display device 20 can be rotated up to 180° by pressing the pulled out eyepiece 130, there is no problem in actual use.

On the other hand, if the above-described erroneous detection prevention means is not taken, the display device 20 can be tilted upward to an angle close to 180° when taking a self-portrait, for example, with the eyepiece 130 of the electronic viewfinder 10 pulled out. The display on the display device 20 stops when the rotating operation is performed. Therefore, it is not possible to shoot while confirming the image.

So far, the liquid crystal display 21 is used as the display device 20 and the organic EL panel 121 is used as the electronic viewfinder 10 as examples of display means. Other display means may be used as long as the display is possible.

Further, the hinge device 30 has two vertical axes of rotation A and B, and the display device 20 can be rotated upward by 180° and downward by 45° with respect to the main body of the imaging device 1. Although illustrated, the hinge device 30 may have only an upper axis of rotation A. In this case, the display device 20 can only rotate upward and cannot rotate downward. However, there is a similar problem that the proximity sensor 14a erroneously detects when the display device 20 is rotated upward by nearly 180°, and this embodiment can be applied.

Also, in this embodiment, the proximity sensor 14a and the proximity sensor window 14 are provided on the upper frame of the display device 20, but the present invention is not limited to this. As long as it can be placed in the display device 20, the position is not particularly limited to the upper side, but may be the side or the lower side. However, when providing the proximity sensor window portion 14 on the upper frame portion of the display device 20 , it is desirable not to place it directly below the eyepiece portion 130 of the electronic viewfinder 10 . If the display device 20 is rotated upward by about 90° with the eyepiece 130 pulled out, the detection range of the object by the proximity sensor 14a shown in FIG. The eyepiece 130 enters inside, and the display of the display device 20 disappears.

Also, the proximity sensor 14 a and the proximity sensor 14 may be provided on the rear surface of the imaging device 1 or the eyepiece section 130 of the electronic viewfinder 10 instead of the display device 20 . In this case, the arrangement is not limited as long as the position is not covered by the display device 20 when the display device 20 is in the basic posture (reference position) shown in FIG. 1(b). When the proximity sensor 14a and the proximity sensor window 14 are arranged on the main body side of the imaging device 1 or on the eyepiece 130 of the electronic viewfinder 10, when the display device 20 is rotated upward by nearly 180 degrees, There is a similar problem that the proximity sensor 14a makes false detections. Therefore, even in such an arrangement, the present embodiment that prevents erroneous detection of the proximity sensor 14a can be applied.

Next, an imaging device 1a according to Embodiment 2 of the present invention will be described. In the first embodiment, in order to prevent erroneous detection of the proximity sensor 14a, when the display device 20 is rotated by a predetermined angle (for example, by 90°), the display cover 22 of the display device 20 is moved to the eyepiece portion (limiting position) of the electronic viewfinder 10. portion) 130, ie, the exterior portion. On the other hand, in the present embodiment, a method of preventing erroneous detection of the proximity sensor 14a while protecting the exterior portion by abutting at a location that is difficult to see from the exterior will be described. In the present embodiment, the basic configurations of the main body of the imaging device 1a, the electronic viewfinder 10, the display device 20, and the hinge device 30 are the same as those of the first embodiment, and thus the description thereof will be omitted. Only the configuration different from that will be described.

A method for preventing erroneous detection by the proximity sensor 14a due to contact between the display device 20 and the electronic viewfinder 10 at a location where it is difficult to see from the outside will be described with reference to FIG. FIG. 11 is a cross-sectional view of the main part of the imaging device 1a in this embodiment. FIG. 11A shows a state in which the eyepiece 130 of the electronic viewfinder 10 is pulled out and the electronic viewfinder 10 is ready for use (the state in which the electronic viewfinder 10 is at the use position). FIG. 11B shows a state in which the electronic viewfinder 10 is in a usable state (a state in which the electronic viewfinder 10 is in the use position) and the display device 20 is rotated upward by 90° (a state in which the display device 20 is moved from the reference position). ) is rotated by a predetermined angle).

As shown in FIGS. 11A and 11B, a restricting portion (restricting portion, protruding portion) 136 is formed below the eyepiece portion 130 . The restriction portion 136 is formed directly on the eyepiece portion 130 and advances and retreats in conjunction with the operation of pulling out the eyepiece portion 130 . When the eyepiece 130 is pulled out as shown in FIGS. 11A and 11B, at least part of the restricting portion 136 protrudes from the main body of the imaging device 1a.

When the display device 20 shown in FIG. 11A starts rotating upward from the state of the basic posture (reference position), the display cover 22 constituting the display device 20 also starts rotating. The display cover 22 is provided with a contact portion 22b. When the display device 20 continues to rotate and rotates upward by 90° as shown in FIG. abuts on the restricting portion 136 formed in the . When the display device 20 is further rotated, the display device 20 rotates further upward due to the contact between the contact portion 22b provided on the display cover 22 and the restriction portion 136 formed on the eyepiece portion 130. I can't.

In this manner, when the eyepiece 130 of the electronic viewfinder 10 is pulled out, the upward rotation of the display device 20 beyond an angle of about 90° is restricted. Therefore, the main body of the imaging device 1a does not enter the object detection range 14b of the proximity sensor 14a, and erroneous detection of the proximity sensor 14a does not occur. Further, the abutment between the abutting portion 22b provided on the display cover 22 and the restricting portion 136 formed on the eyepiece portion 130 is at a location where it is difficult to see each other from the outside. It is possible to limit the rotational movement while In this embodiment, the restricting portion 136 is formed directly on the eyepiece portion 130, but the present invention is not limited to this, and the restricting portion 136 is provided separately from the eyepiece portion 130. may In this case, when the eyepiece portion 130 is pulled out, the restricting portion 136 may be interlocked with the eyepiece portion 130 and protrude from the imaging device 1a.

Thus, in each embodiment, the imaging device includes a rotatable display (display device 20), an eyepiece 130 movable between a retracted position and a use position, and an eyepiece in the use position. It has a restriction part (eyepiece part 130, restriction part 136) that restricts the rotation of the display part in the state.

Preferably, the restricting portion is an eyepiece, and when the display is rotated by a predetermined angle from a reference position (basic posture state) while the eyepiece is in the use position, the display is aligned with the eyepiece. The rotation of the display portion is restricted by the abutment. Preferably, the restricting portion is a projecting portion that moves in conjunction with the movement of the eyepiece, and when the display is rotated by a predetermined angle from the reference position while the eyepiece is in the use position, the display is moved. abuts against the restricting portion to restrict the rotation of the display portion. More preferably, the predetermined angle is 90°.

Preferably, the imaging device includes first detection means (detection switch 123) for detecting that the eyepiece has moved to the use position, and second detection means (proximity sensor 14a) for detecting proximity of an object. have. The imaging device also has control means (CPU 60) that performs predetermined control when an object approaches the second detection means. The control means performs predetermined control when the first detection means detects the movement of the eyepiece to the use position. On the other hand, the control means does not perform the predetermined control when the first detection means has not detected the movement of the eyepiece to the use position. More preferably, the predetermined control is a control of not performing display on the display section but displaying on the eyepiece section when the second detection means detects the proximity of the object. Further, the predetermined control is control to perform display on the display unit without displaying on the eyepiece unit when the second detection means does not detect the proximity of the object. More preferably, in a state in which the restricting unit restricts the rotation of the display unit, the main body of the imaging device is positioned outside the detection range of the object by the second detection means (the main body of the imaging device is located outside the detection range of the object). not within the detection range 14b).

Preferably, the second detection means is arranged above the display. More preferably, the second detection means is arranged at a position retracted from the lower portion of the eyepiece. Further, preferably, the second detection means is arranged above the back side of the main body of the imaging device. Also preferably, the second detection means is arranged in the eyepiece.

Preferably, the eyepiece is movable from the retracted position to a position inside the main body of the imaging device (a state in which the eyepiece is stored in the main body of the imaging device). Preferably, the display section is a liquid crystal display provided on the back surface of the imaging device, and the eyepiece section constitutes an electronic viewfinder.

According to each embodiment, it is possible to provide an imaging apparatus capable of reducing erroneous sensor detection due to rotation of the display unit.
