Abstract

PURPOSE:To photograph a subject while a lens barrel is freely moved by holding only the lens tube with hands by transmitting the output of an image pickup element to a camera main body under the condition where the camera main body is separated from the lens tube. CONSTITUTION:At the time of photographing, an electronic camera main body 1 is connected to a replacement lens barrel 5 through a transmission means 8. Namely, a main fitting part 6 of said tube 5 is fitted in a lens fitting part 8b1 of the 1st holder ub of the transmission means 8, and further fitted in a lens fitting part 2 of the camera main body 1 and sub-fitting part 8c1 of the 2nd holder 8c of the transmission means 8. Then an electrically connected terminal provided on the main fitting part 6 and an electrically connected terminal provided on the sub-fitting part 8c1 are connected to an electrically connected terminal 8b2 of the lens fitting part 8b1 and a connection terminal 3 of the lens fitting part 2 of the camera main body, respectively. The signal which is converted into an electrical signal by the image pickup element is led to the electronic camera main body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an electronic camera in which a transmission means is interposed between a camera body and a lens barrel.

[Prior art]

In recent years, light from a subject that enters through a lens barrel is
CD (charge-coupled device)
Electronic cameras are known in which an image sensor such as e) converts an image into an electrical signal and records the electrical signal in a recording device such as a magnetic disk device. The recording device is generally heavy, and it is cumbersome to take pictures while holding the camera housing the device in one's hand, resulting in a problem of lack of operability.

〔the purpose〕

The present invention was made in view of the above-mentioned problems, and it is an object of the present invention to provide an electronic camera with good operability by reducing the burden on the operator.

〔Example〕

FIG. 1 is a perspective view of essential parts showing an embodiment of the present invention.

In the figure, 1 is a camera body, 2 is a lens barrel provided on this camera body, and this embodiment employs a bayonet system. Reference numeral 3 denotes an electrical connection terminal attached to this lens barrel 2, 4 a release button, and 5 an interchangeable lens barrel. A main lens barrel 6 is attached to the rear end of this lens barrel. Reference numeral 7 denotes a photographic lens provided in the interchangeable lens barrel 5, and 8 denotes a transmission means, which includes a connection cord 8a made of a connectable material, a first holder 8b provided at both ends of this connection cord 8a, and It consists of a second holder 80. A lens barrel 8b1 is attached to the first holder 8b.
The lens barrel 8b1 is adapted to fit into the main barrel 6 of the interchangeable lens barrel 5.

Further, the electrical connection terminal 8b2 attached to the lens barrel 8b1 is connected to the electrical connection terminal 8b2 attached to the main lens barrel 6.
(not shown). The second holder 80 is provided with a sub-fitting part 8C1, and the sub-fitting part 8C1 is adapted to fit into the lens barrel 2. Further, an electrical connection terminal (not shown) attached to this sub-attached portion 8C1 is connected to the electrical connection terminal 3. An electrical conductor such as a lightning bolt or wire is provided inside the connection cord 8a to connect the electrical connection terminal 8b2 and an electrical connection terminal (not shown) attached to the sub-connection part 8C1. 0ru0 Note that a 1' element (not shown) such as a COD is disposed at the tilted position of the imaging lens T.

Further, the main lens barrel 6 of the lens barrel 5 is directly attachable to and detachable from the lens barrel 2 of the camera body 1.

In the electronic camera configured as described above, the interchangeable lens barrel 5 is connected to the electronic camera body 1 via the transmission means 8 when taking pictures.
connected to. That is, the main barrel 6 of the interchangeable lens barrel 5
is fitted into the lens barrel 8b1 of the first holder 8b, the sub-fitting part 8C1 of the second holder 80 is fitted into the lens barrel 3 of the camera body 1, and the electrical connection terminal provided on the main barrel 6 is fitted. and the electrical connection terminal 8b2 of the lens barrel 8b1, and the electrical connection terminal provided in the sub-forming part 8C1 and the lens barrel 2.
is connected to the electrical connection terminal.

It will be done.

A photographer can hold only the interchangeable lens barrel 5 in his hand while placing the heavy electronic camera body 1 on the ground, for example, and can take pictures while freely moving the interchangeable lens barrel 5. Therefore, this electronic camera is very easy to operate.
Especially suitable for shooting in confined spaces.

Note that in the XtM example above, a case was explained in which the camera body 1 and the interchangeable lens mirror m5 are electrically connected using the transmission means 8, but it is also possible to use a photoconductor such as an optical fiber as the transmission means 8. The connection may be made optically.

〔effect〕

As explained above, the present invention has good operability because it is possible to take pictures while holding only the lens barrel by hand and moving it freely, and has the advantage that it is particularly easy to take pictures in narrow places.
