The type of drive recorder attached to the windshield as in Patent Document 1 has a problem that the mounting place is troublesome and the visibility is obstructed. The drive recorder integrated with the rear-view mirror as in Patent Document 2 has a problem that installation work by a specialist is required.

Therefore, an object of the present invention is to provide an electronic device or the like capable of taking an image in an appropriate direction without obstructing the visual field without performing installation work by a specialist.

The electronic device of the present invention made to achieve the above object is (a) an electronic device having a camera, and is mounted on a vehicle equipment installed so that the facing angle to the driver's seat can be changed. A portion and a protruding portion that protrudes beyond a predetermined side position of the vehicle equipment at the time of mounting are provided, and the protruding portion includes a protruding portion that protrudes in a direction different from the protruding direction of the protruding portion. It is preferable that the unit is provided with the camera and means for changing the shooting direction of the camera.
By doing so, it is possible to provide an electronic device or the like capable of taking an image in an appropriate direction without obstructing the visual field without performing installation work by a specialist.
Since these vehicle equipments are equipped as necessary by themselves, even if there is a protruding portion that protrudes beyond a predetermined side position of the vehicle equipment when mounted on the vehicle equipment, it will greatly obstruct the view. It's hard to get rid of. Further, as a result of the structure that the angle can be changed with respect to the driver's seat, the angle of the electronic device attached to the vehicle equipment also changes with the angle adjustment of the vehicle equipment, but the image pickup direction of the camera is in the desired direction. Can be turned to. In particular, since the camera and the means for changing the shooting direction of the camera are provided in the protruding portion protruding in the direction different from the protruding direction, even if the size of the camera or the means for changing the shooting direction of the camera becomes large, the visibility is greatly obstructed. It's hard to get rid of.
The camera may be a camera that captures the situation in the vehicle, and in particular, a camera that captures the situation inside the vehicle, for example, the situation of the driver, or the situation outside the vehicle interior, for example, the situation around the outside of the vehicle. It is good to use a camera, especially a camera that shoots the front of the vehicle.
As the vehicle equipment, for example, the equipment may be installed in the vehicle interior. Further, for example, it may be assumed that the vehicle itself is equipped in advance. In particular, it is preferable that the vehicle itself is pre-equipped and is installed in the vehicle interior. For example, a rear-view mirror may be used.
The predetermined end position may be the end of the vehicle equipment that is less likely to interfere with the driving of the vehicle. For example, if the vehicle equipment is a rear-view mirror, it may be one of the upper end, the left end, and the right end of the rear-view mirror. For example, in the case of a rear-view mirror, for example, the protrusion to the upper end position, the left end position, and the right end position rather than the lower end position is preferable because it is an end portion that does not easily interfere with the driving of the vehicle. Further, the predetermined end position may be an end portion that does not easily obstruct the line-of-sight in the imaging direction by the camera. For example, in the case of a rear-view mirror, the upper end position should be an end other than the upper end because there is a smoked portion or the like on the upper part of the windshield and it tends to obstruct the line of sight in the image pickup direction by the camera.
The mounting portion may be configured to be mountable on the same type of vehicle equipment installed in a plurality of vehicles of different vehicle types. In particular, it is preferable to configure the mounting position so that it can be mounted from the largest size of vehicle equipment of the same type to the smallest size of vehicle equipment of the same type. The size that can be accommodated should be determined to be the size that can accommodate the vehicle equipment of as many vehicle types as possible.
The protruding direction of the protruding portion may be a direction that does not include a component in the protruding direction of the protruding portion. By doing so, it is less likely to interfere with driving. For example, the direction may be orthogonal to the protruding direction of the protruding portion. By doing so, it is possible to prevent the protrusion from hitting the electronic device, as well as to prevent the operation from being hindered.
(B) The mounting portion is configured to cover and mount at least a part of one side of the vehicle equipment, and the protruding portion protrudes to a position beyond the surface opposite to the one side of the vehicle equipment. It is preferable that at least a part of the means for changing the shooting direction of the camera is provided at the position exceeding the above position.
In this way, it becomes difficult for the vehicle equipment to be hit by a means for changing the shooting direction of the camera. In particular, if all of the means for changing the shooting direction of the camera are provided at the positions exceeding the above, for example, the means for changing the shooting direction of the camera does not hit the vehicle equipment.
In particular, (c) the protruding portion includes an arm portion connecting a portion having a means for changing the shooting direction of the camera and a portion leading to the protruding portion, and at least a part of the means for changing the shooting direction of the camera. In the case of a configuration having a portion protruding from the arm portion on the side opposite to the protruding direction, it becomes difficult for the means for changing the shooting direction of the camera to hit the vehicle equipment. For example, the protrusion is composed of a spherical part having a camera or a means for changing the shooting direction of the camera, and an arm part that supports the spherical part with a width smaller than the diameter of the spherical part, and a part of the sphere protrudes from the arm part. It may be configured as a portion protruding in the direction opposite to the direction.
(D) The means for changing the shooting direction of the camera may be configured to include a semi-fixed structure capable of changing the direction of the camera in the vertical and horizontal directions and fixing the direction of the camera when shooting the camera. ..
