In those drawings, a photographic lens 12 for photographing a subject is built into the front part of the camera body 11, and a charge transfer element (CO) arranged at the rear of the photographic lens 12 captures the subject image.
The image is formed on the image sensor 13 such as D). Further, a small bee-finder cathode ray tube 14 is built into the rear of the camera body 11 for checking the image to be photographed. The image projected on the cathode ray tube 14 is transmitted through the magnifying lens 15. It can be seen through the eye cap 16. Further, on the left side surface 11a of the camera body 11, there is a focus lever 17 for focusing the photographing lens 12. Zoom Control 'H-rfx Uzoom Repa 182 Color Temperature Selection Switch 19. White Hallance Swissochi 2o, Hue Con) 0-Rutsumami 21. Iris control knob 22
etc. are arranged. The focusing distance scale number 23 is still near the focus lever 17, and the zoom lever 18
A scale number 24 indicating the focal length of the photographic lens 12 is printed or engraved.

As shown in FIG. 3, a detection element 25 for vertical direction detection is installed inside the camera body 11. As shown in the enlarged sectional view of FIG. 4, this detection element 25 is provided with a pair of contacts 27a and 27b on the upper and lower sides of a glass case 26, and mercury 28 is sealed inside the glass case 26. Therefore, when the contact point 27a is located downward, the mercury 28
When the contact 27a becomes conductive, and when the camera body 11 is turned upside down and the contact 27 is downward, as when the camera body 11 is turned over, the contact 27b becomes conductive, thereby detecting the attitude of the camera body 11. can do. Detection element 2
5 is connected to a scanning direction conversion circuit 30 via a manual operation circuit 29, and is configured to be able to convert the scanning direction of the image sensor 1 and the plow/pipe 14 upside down. Further, the output of the image sensor 13 is converted into a normal television signal by a signal processing circuit 31 and supplied to an output terminal 32 and a cathode ray tube 14. Incidentally, the cathode ray tube 14 and the photographing lens 12 are located approximately at the vertical center of the camera body 11, as shown in FIG.

The positions of the left and right hands and eyes are opposite to those for right-handed people, and the video camera body 11 is held by supporting the 11d and 100 sides of the video camera body 11 with the thumb of the left hand and the 100 side with the other fingers.
Focus lever 17. with right hand. Operate the zoom lever 18, etc.

It's a waste of time, so I put my left eye on the eye cap 16 and take a picture while checking the subject, switches, etc. with my right eye.

At this time, the detection element 26 detects the front and back orientation of the camera body, and the scanning direction conversion means 30 detects the direction of the image sensor 1.
3 and the scanning direction (deflection direction) of the cathode ray tube 14 are upside down, so the output terminal 32 outputs a television signal whose positional relationship -]2 and below is in the same direction as the subject.

In addition, a manual selector switch 3 installed near the eye camp
3 is connected to the manual operation circuit 29, and by operating the manual changeover switch, it is possible to turn the photographed image upside down, and regardless of the detection result of the detection element 26, the vertical direction of the image can be turned upside down. Can be set arbitrarily.

In addition, although the above-mentioned embodiment explained the case where the scanning direction conversion circuit was used, even if the image sensor and the cathode ray tube are rotated upside down, it is relatively the same and has the same function. It is.

Effects of the Invention As is clear from the above description, the present invention includes a photographing lens for photographing a subject, a photoelectric conversion means for converting an optical image formed by the photographing lens into an electrical signal, and a method for confirming the image photographed by the photographing lens. a finder for detecting the vertical direction of the photoelectric conversion means; a detection means for detecting the vertical direction of the photoelectric conversion means; and a scanning device for detecting the direction of the photoelectric conversion means by the detection means and reversing the scanning direction of the photoelectric conversion means when the photoelectric conversion means is held upside down. Since the configuration includes a direction changing means, a left-handed user can have the same operability as a right-handed user,
Moreover, since the scanning direction of the image sensor can be automatically switched by simply turning the camera body upside down, there are no operational errors and excellent effects can be obtained. Additionally, since the camera body is held directly by the handle, there is no need to attach or replace the grip.
