Abstract

PURPOSE:To lighten the burden imposed on an operator with respect to the weight of a camera and to improve the operability of an operational switch by providing a switch for controlling a circuit in a camera main body on a lens barrel. CONSTITUTION:A replacement lens tube 5 is fitted in the 1st holder 8b, and connected to the 2nd holder 8c through a connection cord 8a. The 2nd hold 8c is fitted in a lens fitting part 2 and attached to a camera main body 1. Since an operational switch 9 is provided on the replacement lens barrel 5, only the barrel 5 is held with hands, while, for instance, the camera main body 1 is placed on the ground, and the operational switch 9 is operated by moving the tube 5 freely to control the circuit in the camera main body, thereby photographing a subject.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical details] The present invention relates to an electronic camera that converts light from a subject incident through a lens barrel into a drowsiness signal using an image sensor and records this signal, and to the lens barrel.

[Prior art]

In recent years, the light from the subject that enters through the lens barrel has been
OD (charge-coupled device)
Electronic cameras are known in which an image pickup device such as ) converts an electric signal into an electric signal, and records this electric 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 incorporating the device in one's hand, resulting in a problem of lack of operability.

〔the purpose〕

This invention was made by focusing on the above-mentioned problems, and reduces the burden on the operator regarding the NFC of the camera.
Another object of the present invention is to provide an electronic camera and a lens barrel with improved operability.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, 1 is a camera body, 2 is a lens mounting portion provided on the camera body, and this embodiment employs a bayonet system. 3t1 is an electrical connection terminal attached to the lens attachment part 2; 4 is a release button; 5 is an interchangeable lens barrel; a main attachment part 6 is attached to the rear end of this lens barrel.

7fi is a photographing lens provided in this interchangeable lens barrel 5; 8 is a transmission means, which includes a connection cord 8a made of a flexible material, a first holder 8b provided at both ends of this connection cord 8a; It consists of two holders 80. The first holder 8b is provided with a lens attachment portion 8bi, which is adapted to fit into the lens attachment portion 8b+ij and the main attachment portion 6 of the interchangeable lens barrel 5. Further, the electrical connection terminal 8bz attached to the lens attachment portion 8t)t is connected to an electrical connection terminal (not shown) attached to the main attachment portion 6. The second holder 8cK is provided with a sub-fitting part 8C1, and this sub-fitting part 8cs is adapted to fit into the lens attachment part 2.

Further, an electrical connection terminal (not shown) attached to this sub-attached portion 8c+ is connected to the electrical connection terminal 3. An electrical conductor such as an electric 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-assembly part 8C1.

Reference numeral 9 denotes an operation switch provided on the lens barrel 5, which is used to control a circuit within the camera body.

Note that an imaging device (not shown) such as a COD is placed at the imaging position of the imaging lens 7.

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

When an electronic camera configured as described above takes a picture,
After connecting the interchangeable lens barrel 5 to the camera body l via, for example, the transmission means 8, hold only the interchangeable lens barrel 5 by hand while leaving the camera body l on the ground, for example. Operation switch 9 at hand while moving freely
You can control the circuit inside the camera body and take pictures.

2. In the above embodiment, the camera body l and the interchangeable lens mirror m
5 is electrically connected using the transmission means 8, but the transmission means 8 may be optically connected using a photoconductor such as an optical fiber.

〔effect〕

As explained above, the present invention has the effect of significantly reducing the burden on the operator regarding the M amount of the camera, and also improving the operability of the operation switch.
