Description

DETAILED DESCRIPTION OF THE INVENTION <Public Expenses for Industrial Use> The present invention relates to a video camera recorder such as a camera-integrated VTR or an electronic still camera that can be remotely controlled.

<Prior Art> A camera-integrated VTR includes a VTR body that stores a videotape as a recording medium and records and plays back images, a lens block having an imaging lens, and a viewfinder for checking the shooting state.

Such a camera-integrated VTR can be used by a user holding it in his hand or by attaching it to a tripod and remotely operating it using a remote control. Of these, when remote control is used, the camera-integrated V
It is necessary to automatically perform panning (horizontal movement wD) or tilting (vertical movement) to match the TR to the subject.

Conventionally, an electric pan head was attached to the lower part of a camera-integrated VTR, and the camera was panned and tilted by driving two drive motors built into the electric pan head.

Camera-integrated VTRs have been made lighter in recent years, and their weight is approximately 6 kg.

This camera-integrated VTR has been designed to be lightweight in consideration of its operability and portability, but as mentioned above, attaching an electric pan head for remote control of the camera-integrated VTR is heavy. There is a problem in that the number of devices increases and the size of the device increases.

On the other hand, it has been proposed that an electric pan head for panning and tilting the camera-integrated VTR is built into the camera-integrated VTR instead of being attached as a separate member. For example, Japanese Utility Model Application Laid-Open No. 63-183765 discloses an image pickup lens which is horizontally rotatable by a rotation mechanism. Japanese Utility Model Application Publication No. 63-16759 discloses an imaging lens that is rotatable in the vertical direction by a support shaft member.

<Problems to be solved by the invention> In the conventional camera-integrated VTR described above, the imaging lens that rotates vertically or horizontally protrudes outside, making it large and lacking in completeness in terms of design. There were problems such as low quality, poor appearance quality, and difficulty in operation.

The present invention is intended to solve these problems, and aims to provide a video camera recorder that is small and lightweight, has good operability, and has an excellent design.

Means for Solving the Problems> A video camera recorder of the present invention for achieving the above-mentioned object has a main body that stores a recording medium, an imaging lens, and is rotatably provided on the side of the main body. a viewfinder having a remote control transmitting/receiving section and being detachably attached to the main body; a remote control transmitting/receiving section of the viewfinder that is fixable to the main body and rotatable together with the lens block; The device is characterized by comprising a remote control transmitting/receiving section for transmitting and receiving.

Further, in the video camera recorder of the present invention, in a video camera recorder in which a main body for storing a recording medium is provided with a lens block having an imaging lens and a viewfinder, the optical input axis of the imaging lens is connected to the lens block. A reflecting plate with a variable reflection angle is arranged in front of the imaging lens, and an imaging element is arranged at a rear side of the imaging lens, and at least the reflecting plate and The image pickup device is characterized in that the image pickup device is rotatably supported with respect to the optical input axis of the image pickup lens.

Function> A lens block is rotatably provided on the side of the main body, and a viewfinder is also removably provided, and a remote control transmitter/receiver that sends and receives signals to and from the viewfinder can be fixed to the main body and rotates with the lens block. By being movable, each member is appropriately arranged, resulting in an excellent design and improved operability.

Moreover, operability is further improved by making the remote control transmitting and receiving section of the main body fixed or rotatable together with the lens block depending on the usage state of the video camera recorder.

Further, the imaging lens of the lens block is arranged so as to be substantially perpendicular to the optical input axis to the lens block, and the reflection plate is arranged in front of the imaging lens, and the imaging element is arranged behind the imaging lens.
Since the reflector and image sensor are rotatably supported, the lens block becomes more compact and the video camera recorder becomes smaller and lighter.
