Abstract

PURPOSE: To use the EVF equipment in common for a light shield member against an external light by forming a liquid crystal display panel and a cover to be turnable and controlling the changeover between viewing via an eyepiece and direct viewing of a screen in one operation. CONSTITUTION: When a liquid crystal display panel 2 is desired of view from an upper side of a position 12', a cover 5 is lifted up to be at a position 5', then the panel 2 is turned around a shaft 7 with a holder 4 to be at a position 2'. Since a projection 4a or 4b of the holder 4 is energized in a direction of the arrow A by a plate spring 6, the holder 4 is held at a horizontal or a vertical position. Moreover, since the cover 5 is moved integrally with the holder 4 by a screw 8, the cover 5 is similarly held. The cover 5 acts as a light shield member against an external light for the panel 2 by jumping up the cover 5 to be at a position 5'.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camcorder E.
It relates to a VF device.

[0002]

2. Description of the Related Art FIG. 5 is a view showing an internal arrangement of a conventional EVF, 1 is an EVF main body, 2 is a liquid crystal panel, and 3 is an eyepiece whose diopter can be adjusted by a known mechanism (not shown). It is a lens and the photographer can see the screen only through the eyepiece as shown.

A conventional EVF device is a liquid crystal or C
I was looking at the RT (CRT) screen through the eyepiece that also serves as the diopter adjustment, or directly at the screen. Also,
In some cases, the eyepiece was removed to allow direct viewing.

[0004]

In most of the conventional examples, there is no switching between viewing the screen through the eyepiece and directly viewing it, and the switching is of the type in which the eyepiece unit is detachable. However, it was not one-touch and it took time. Further, particularly in the case of a liquid crystal screen, it becomes difficult to see in a place where the external light is strong, and it is necessary to prepare a light shielding member for that purpose.

The present invention has been made in order to solve such a conventional problem. When the screen is viewed, it is possible to quickly select whether to pass through the eyepiece lens or not by a simple structure, and further, a liquid crystal screen or the like. It is an object of the present invention to provide an EVF device that can also serve as a light shielding member in the case of.

[0006]

In order to achieve the above object, the EVF apparatus of the present invention is the EVF apparatus according to claim 1, wherein the EVF apparatus is provided with an image display section and an eyepiece lens. From the visible position of this EV
A part of the exterior of the F device and the image display unit move in conjunction with each other, and have a second visual recognition position where the image display unit can be seen without passing through an eyepiece lens.
A part of the exterior of the VF device moves and does not pass through the eyepiece, and has a third visual recognition position where the image display portion can be seen. Further, in the third visual recognition position according to claim 3, A part of the exterior of the interlocking EVF device also serves as a light-shielding member, and in claim 4, at the third visual recognition position, a part of the exterior that moves also serves as a light-shielding member. , In claim 5,
The image display unit is a liquid crystal panel, CRT, or other display device.

[0007]

In the present invention, the screen can be switched between one-touch mode, that is, the case where the screen is viewed through the eyepiece and the case where the screen is directly viewed, and the mechanism can also serve as a light-shielding member against external light.

[0008]

1 to 3 are views showing a first embodiment of the present invention, FIG. 1 is an internal structural view thereof, and FIG. 2 is a perspective view of the whole.
FIG. 3 is a configuration diagram of the EVF portion.

1 to 3, the liquid crystal panel 2 is fixed to a holder 4 together with a backlight unit, a circuit board and the like (not shown). The holder 4 is supported rotatably around a shaft 7 (direction of arrow B), and has projections 4a and 4b at one end. Reference numeral 5 denotes a lid provided on the EVF main body 1, which is also rotatable around the shaft 7. The holder 4 and the lid 5 are fixed by screws 8.
Reference numeral 6 is a metal or molded leaf spring having a spring property, and although not shown, both ends or one end is EV with a screw or the like.
It is fixed to the F body 1 and urges the protrusion 4a or 4b in the direction of arrow A. Reference numeral 9 is a washer or E-ring type, which is used for removing the shaft 7. 10 is a diopter ring, 11
Is a main body of the camcorder, and 12 is an eye of a photographer or a person equivalent thereto.

In FIG. 1, when the photographer or an equivalent person wants to see the screen from the top (position 12 '), the lid 5 is used.
When is pulled up to the position of 5 ', the liquid crystal panel 2 also rotates around the shaft 7 together with the holder 4 and comes to the positions of 4'and 2', respectively. Since the protrusion 4a or 4b of the holder 4 is biased by the leaf spring 6, the holder 4 is held in a horizontal and vertical position. Since the lid 5 also moves integrally with the holder 4 by the screw 8, the lid 5 is also held in the same manner. Further, the lid 5 also serves as a light blocking member for the outside light of the liquid crystal 2 when the lid 5 is flipped up. Here, in the present embodiment, the holder 4 is provided with two positions 4a and 4b, but it is also possible to increase the number and stop at a finer angle. Although not shown, the EVF main body 1 can move rotatably on the camcorder 11, as is well known.

FIG. 4 shows a second embodiment of the present invention. The difference from the above is that the lid 5 and the holder 4 are not fixed, and only the lid 5 is opened and closed around the shaft 7. The protrusions 4 a and 4 b are formed on the lid 5, not on the holder 4. Photographer 1
2'can see the liquid crystal panel from diagonally above.

[0012]

As described above, according to the first and second aspects of the present invention, the photographer or a person equivalent thereto directly sees the liquid crystal portion (or the tube surface) which is the image display portion through the eyepiece lens. Viewing can be performed by a simple one-touch operation. Further, according to the third and fourth aspects, since the lid also serves as the light shielding member, a clear image can be viewed with a simple structure. Further, according to claim 5, since the image display unit is a liquid crystal panel, a CRT, or other display device,
Various displays can be made.
