Abstract

PURPOSE:To make the removal of a power supply battery from being disabled in the photographing state by providing a relating mechanism blocking the opening/closing of the battery storage cover at finder projection between a finder and the battery storage cover. CONSTITUTION:When a finder 5 is projected from the containing position shown in solid lines, an operating pin 5b turns clockwise in a direction of arrow A a lock member 9 energized counterclockwise by a spring provided to the camera main body 1 against the energized spring to keep the lock arm 9a to be entered between double parts 7a of the battery storage over 7. Thus, the battery storage cover 7 cannot be opened in the photographing state where the finder 5 is projected and then the power battery 6 cannot be removed. Thus, the removal of the power battery during photographing carelessly is prevented completely.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a still video camera, and more particularly to a still video camera of a type in which a finder protrudes during photographing.

(Background of the Invention) Still video cameras magnetically record image information, etc. on video floppies using complex control of electronic circuits, so if the power is cut off during shooting, the control may go out of order and malfunctions may occur. , breakdowns are likely to occur.

Furthermore, if the power is cut off while the floppy is rotating, a sudden force is applied between the floppy and the magnetic recording head, which may damage the floppy.

The inventors of the present invention have come up with the idea that the above-mentioned problem can be easily solved by using a finder in a still video camera in which the finder protrudes during shooting.

[Purpose of the invention]

The present invention has been made based on the above-mentioned idea, and aims to provide a still video camera that clearly recognizes that it is in a shadowing state, and in which the power battery cannot be removed in the shadowing state.

[Structure of the invention]

The present invention consists of 1. A still video camera of a type in which the viewfinder protrudes during shooting, characterized in that a related mechanism is provided between the finder and the battery storage cover to prevent the battery storage cover from opening and closing when the finder is protruded, This configuration achieves the above object.

〔Example〕

The present invention will be explained below using illustrated examples.

FIG. 1 is a perspective view showing an example of a still video camera of the present invention, and FIG. 2 is a partial perspective view showing an example of a related mechanism between a finder and a battery storage lid.

In the figure, 1 is the camera body, 2 is the shooting lens, 3 is the shooting start button, 4 is the floppy eject button, 5 is the viewfinder that can be moved between the protruding position shown by the dashed line and the storage position shown by the solid line, and 6 is the power supply. Battery, 7 is a battery storage lid.

The finder 5 is provided with a conductive piece 5a, and when the finder 5 is projected to the position indicated by the dashed-dotted line, the conductive piece 5a comes into contact with the switch 8 provided on the camera body 1, and the camera then presses the shooting start button 3. When pressed, the button enters the shooting state in which image information, such as image information, is magnetically recorded on a floppy disk.

Further, the finder 5 is also provided with a working pin 5b. When the finder 5 is protruded from the storage position indicated by the solid line, the action pin 5b springs the locking member 9, which is biased to rotate counterclockwise by a spring (not shown) provided on the camera body 1. The lock member 9 is rotated clockwise in the direction of arrow A against the bias, and the lock arm 9a of the lock member 9 is inserted between the double portion 7a of the battery storage lid 7 with the finder 5 in the protruding position. hold in state. Therefore, in the photographing state in which the finder 5 protrudes, the battery storage lid 7 cannot be opened and the power source battery 6 cannot be removed.

In the illustrated example, the battery storage lid 7 is removable so that the protruding piece 7b on the opposite side of the double part 7a is engaged with the inside of the camera body 1, and the double part 7a side is opened and closed in the direction of arrow B. However, the present invention is not limited to this, and it may be hinged to the camera body 1, or may be of a sliding type.

In the case of a sliding opening/closing type, the locking member 9 may be locked with a hook. 7C is a handle used to open and close the battery storage lid 7.

If you push down the finder 5 from the protruding position to the retracted position,
The conductive piece 5a comes out of contact with the switch 8, and the camera enters a non-photographing state in which magnetic recording is not performed even if the photographing start button 3 is pressed. At the same time, the action pin 5b separates from the locking member 9 and releases its action on the locking member 9, so the locking member 9 rotates counterclockwise due to the spring bias, and the double portion 7a of the battery storage lid 7 Therefore, the battery storage lid 7 can be opened by the handle 7c and removed. That is, the power battery 6 can be removed and replaced only in a non-photographing state with the finder 5 in the retracted position.

As described above, it is possible to completely prevent the power supply battery from being inadvertently removed during shooting. But if finder 5
If the power supply battery 6 were to be inadvertently pushed down to the storage position during photographing, a problem similar to that caused by the removal of the power battery 6 would occur in the above example. This problem can be solved by, for example, providing an electromagnetic locking member that prohibits the viewfinder 5 from being pressed down while the video floppy is rotating, or by turning off the switch 8 and releasing the power switch after one shooting time. This can be easily prevented by using a switch in a switching circuit that is

〔Effect of the invention〕

The still video camera of the present invention clearly recognizes that it is in the shooting state, and the power battery cannot be removed in that state, so it is possible to prevent problems caused by the power supply being cut off during shooting. be effective.

Note that the related mechanism between the finder and the battery storage lid in the present invention is not limited to the above-described embodiment.
