Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera-integrated recording device provided with a viewfinder device.

SUMMARY OF THE INVENTION The present invention relates to a camera-integrated recording device such as a camera-integrated VTR equipped with a viewfinder device including a viewfinder body having an image display section and an eyepiece tube having diopter adjustment means. The eyepiece tube is disposed so as to be able to move forward and backward with respect to the viewfinder body, and the view is arranged such that the eyepiece tube is substantially flush with the back surface of the apparatus body such as the VTR body at the time of retreat. By attaching the viewfinder device to the device body via the viewfinder body, the protrusion of the viewfinder device from the device body is reduced, and the overall size of the camera-integrated recording device can be reduced.

[Prior Art] For example, an 8 mm camera-integrated VTR is known.
This will be described in detail with reference to FIGS. 15 and 16. Reference numeral 100 denotes a camera-integrated VTR.
Along with a grip 102 that holds the body 101,
On the opposite side is a VTR composed of a well-known cassette holder, tape loading mechanism, rotating head drum, etc., not shown.
The deck 103 is provided. A camera / lens unit 104 and a microphone 105 are provided in front of a front part 101a of the VTR body 101, and a viewfinder 106 is provided from the upper part of the VTR body 101 on the grip part 102 side to the back.
Is arranged.

The viewfinder 106 has a viewfinder body 107 composed of a pair of upper and lower cases, a CRT (cathode ray tube) (not shown) housed in the viewfinder body 107, a diopter adjusting means 108, an eye cap 109, and the like. It is roughly constituted by the eyepiece tube 110 and the like.

Further, as shown in FIG. 16, a start / stop push-type recording button 111 is provided at a position where the thumb of the back surface 102a of the grip portion 102 of the VTR main body 101 hits. The recording button 111 is located on the back 102a of the grip 102.
The slide button (operation button) 112 that slides in the up and down direction of the vertically long concave portion 102b formed in the vertical direction is visible and hidden.
Unnecessary video recording can be prevented by covering 11. Incidentally, reference numeral 113 in FIG.
It is a grip belt provided on the side surface of.

[Problems to be solved by the invention] However, in the conventional camera-integrated VTR100,
Since the eyepiece tube portion 110 fixed to the viewfinder main body 107 protrudes from the VTR main body 101, there is a disadvantage that the entire camera-integrated VTR 100 becomes longer and larger accordingly.

Accordingly, the present invention provides a camera-integrated VTR that is small and can easily operate operation buttons.

Means for Solving the Problems In a camera body type recording apparatus provided with a viewfinder device including a viewfinder body having an image display unit and an eyepiece tube unit having diopter adjustment means, The eyepiece tube part is disposed so as to be able to move forward and backward, and the eyepiece tube part is attached to the device body via the viewfinder body so as to be substantially flush with the rear surface of the device body when retracted. Was.

[Operation] The eyepiece tube is arranged to be able to move forward and backward with respect to the viewfinder body.
The protrusion from the R body becomes smaller. As a result, the size of the entire VTR can be further reduced.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 to 6, reference numeral 1 denotes an 8 mm camera-type VTR as a camera-type recording apparatus, and a VTR main body 2 as the apparatus main body is formed in a substantially rectangular parallelepiped. The right side of the VTR body 2 is a grip portion 3 for holding the VTR body 2, and a substantially central portion 4a of the left side surface 4 on the opposite side of the grip portion 3 is protruded in a semi-cylindrical shape. Molded and formed. Then, from the lower part of the grip part 3 to the upper part, VT
An R deck 5 is provided. In addition, a camera lens unit 6 is built in a substantially central portion 4a of the left side surface 4, and a lens barrel unit 8 having a zoom lens 7 of the camera lens unit 6.
