[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic camera system including an electronic camera and a camera stand provided with a power feeding means for supplying power to the mounted electronic camera.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a camera stand (charger or the like) having various functions such as supplying power to a mounted electronic camera and charging a secondary battery of the electronic camera. For example, in Japanese Unexamined Patent Application Publication No. 2001-69388, an electronic camera is attached to a charger (camera stand),
It is placed on the front side of the charger (front side of the stand) so that the front of the camera faces, and charging the secondary battery of the electronic camera there,
It describes that correct date setting for an electronic camera, stroboscopic light emission for emphasizing an alarm function, and backlight lighting of a clock display of a charger are performed.

Further, in Japanese Patent Laid-Open No. 2000-333046, an electronic camera is mounted such that an electronic camera is mounted on a charger (camera stand) so that the camera rear surface faces the charger front side (stand front side). The secondary battery is charged, and during or after the charging, a slide show of images based on the image data stored in the electronic camera is displayed on the liquid crystal display unit provided on the back of the camera as the interior of the room. What is done is described.

[0004]

It was necessary to remove the electronic camera from the camera stand and rotate it by 180 °, or rotate the camera stand on which the electronic camera is mounted by 180 °. Further, in the case of a configuration in which the rear side of the camera is placed on the front side of the stand as in Japanese Patent Laid-Open No. 2000-333046, when the remote control signal such as a shooting instruction sent from the front side of the stand is received, the camera Remove the electronic camera from the camera stand in order to direct the remote control signal receiver on the front toward the remote control signal sender.
It was necessary to rotate 80 ° or rotate the camera stand on which the electronic camera is mounted 180 °. In addition, rotating the camera stand by 180 ° in this manner may cause an AC cable provided on the camera stand and various cables (USB cables, etc.) connected to the camera stand to be twisted, which is inconvenient and looks good. It was bad. Further, in such a case, it may be considered that the shape of the camera stand is set so that the front surface and the back surface of the camera are sufficiently exposed in consideration of the fact that the camera stand is rotated by 180 ° and used. However, this may result in insufficient holding of the electronic camera.

In view of the above situation, an object of the present invention is to provide an electronic camera system capable of changing the mounting direction of the electronic camera with respect to the camera stand and enabling a wide range of utilization of the electronic camera mounted on the camera stand. That is.
