Description

[Detailed description of the invention] The present invention relates to a holder for television cameras, and in particular, is a holder used for small home video cameras, etc. It is small and lightweight, and at the same time, it is equipped with a shoulder pad, making it suitable for long-term shooting. The present invention relates to a holder for a television camera that does not cause fatigue to a photographer, and further relates to a holder for a television camera on which a separate viewfinder can be mounted if necessary.

Recently, among television cameras, compact video cameras for home use have become rapidly popular, and compact, low-priced, high-performance, and easy-to-operate models are now on sale. An example is shown in Figure 1. That is, in the figure, a television camera body 1 includes a viewfinder 2, a lens 3, and a hand grip 4.
is installed. Viewfinder 2
It is a TTL (single lens reflex) system, and the hand grip 4 is removably attached to the main body 1 with screws 12.
A start switch operation knob 6 is attached to the front part of the engine via a spring (not shown). This start switch operation knob 6 is interlocked with a switch button 5 provided at the bottom of the camera body 1. Therefore, when the photographer presses the start switch operation knob 6 against the spring, the switch button 5 is pressed and the camera is activated to take a picture. This camera is as light and compact as an 8mm camera, and has improved operability.

However, commonly used home VTRs (video tape recorders) have a continuous recording time of 2
Time is the norm, and more recently, VTRs that can record 6 hours continuously have appeared.
This is a huge difference compared to the time it takes to complete one roll of 8mm film in a few minutes. This means that home video cameras, like 8mm cameras, can take short snapshots of one shot, but at the same time can also take relatively long shots.

Therefore, a home video camera must be as small and lightweight as an 8mm camera, and must be as operable and maneuverable as possible, and at the same time, must have the ability to stably record images for long periods of time without causing fatigue to the photographer. is necessary. However, until now, there has been no camera that satisfies these two functions.

This invention was developed in view of the current situation described above, and it has made it possible to provide a home video camera with two functions: the same mobility as an 8mm camera, and the stability of long-term shooting. The purpose is to provide a holder for television cameras.

In this invention, a hand grip is attached to the front end of a television camera holder (hereinafter simply referred to as the "holder"), a shoulder pad is attached to the rear end, a camera is attached to the center part, the shoulder pad is placed on the shoulder, and the hand grip is grasped. The above objective is achieved by making it possible to operate the camera while using the camera.

Further, as described above, when the camera is placed on the shoulder via a holder, it is impossible to use the view finder built into the camera, and it is necessary to use a separate view finder. The present invention solves this need by providing a viewfinder mounting arm at or near the camera mounting portion of the holder, thereby achieving the above object.

Embodiments of the present invention will be described below based on the drawings. Fig. 2a is a side view showing a small video camera attached to the holder according to the present invention, b is a front view thereof, Fig. 3 is a perspective view of the holder according to the present invention, and Fig. 4a is a side view thereof. ,b is a bottom view.

An L-shaped upper arm (hereinafter simply referred to as "upper arm") 8 for attaching a viewfinder is attached to the lower arm 10, and a viewfinder 7 is attached to the upper arm 8, and its eyepiece 7a is used for photographing. It is mounted so that it protrudes to the side by a predetermined distance from the center of the camera so that it can be easily seen by people.

A shoulder pad 13 is attached to the rear end of the holder body 11 by inserting two screws 15 into a long hole 16 provided at the end and tightening them. The shoulder pad 13 can be tightened by shifting the tightening position of the screw 15 along the long hole 16 (the fourth
(Sliding in direction C in figure a) It is possible to adjust the length to the most suitable length for the photographer, and also with screw 15.
Since it can be rotated around the center (rotation in the G direction in Figure 4 a), it can also be adjusted to the angle most suitable for the photographer, and can be folded when not needed. (The position of the solid line in FIG. 4a) is also possible. The portion of the shoulder pad 13 that comes into contact with the shoulder is shaped into a curve that matches the curve of a human shoulder, and the contact surface is provided with irregularities 13a to prevent slipping.

Next, an interlocking mechanism for interlocking the start switch operating knob 6 and the switch button 5 provided between the front end and the center of the holder body 11 will be explained. In FIGS. 5a and 5b, the plate-shaped connecting member 37 has elongated holes 19 at predetermined locations.
and 21 are bored, and the connecting member 37 is attached to the holder body 11 so as to be slidable in the longitudinal direction by screws 17, 18 and washers 20, 22, which are inserted into the long holes and screwed into the holder body. It is being This connecting member 37 is connected to the holder main body 11
The holder body 11 is biased toward the front end (in the direction of arrow B in the figure) by an L-shaped spring 25 attached to a pin 26 provided in the holder body 11 . The connecting member 37 is provided with elongated holes 30 and 29 at predetermined positions, and boss portions 27 and 28 provided on the holder main body 11 are fitted into the elongated holes. A recess is provided in the center of the boss 27, and a screw hole is provided in the center of the boss 28. A protrusion provided on the handgrip 4 is fitted into the recess, and a protrusion provided on the handgrip 4 is provided in the screw hole.
