Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a still video camera, and more particularly to a still video camera in which a finder is projected during shooting.

[Background of the Invention]

A still video camera magnetically records image information and the like on a video floppy by complicated control of an electronic circuit, so if the power is cut off during shooting, the control is erroneous and malfunctions or failures are likely to occur. . If the power is cut off while the floppy is rotating, a sudden force may be applied between the floppy and the magnetic recording head, which may damage the floppy.

The inventor of the present invention has conceived that, in a still video camera in which a finder is projected at the time of shooting, the above problem can be easily solved by using the finder.

[Object of the Invention]

The present invention has been made based on the above idea, and an object of the present invention is to provide a still video camera in which it is possible to clearly recognize that the camera is in a shooting state and the power supply battery cannot be removed in the shooting state.

[Structure of Invention]

The present invention relates to a still video camera of the type in which a finder is projected at the time of shooting, characterized in that a related mechanism is provided between the finder and the battery housing lid to prevent opening and closing of the battery housing lid when the finder is projected. In the camera, this configuration achieves the above purpose.

〔Example〕

 Hereinafter, the present invention will be described with reference to 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 a camera body, 2 is a photographing lens, 3 is a photographing start button, 4 is a floppy eject button, 5 is a finder which is displaced between a projecting position shown by a chain line and a storage position shown by a solid line, and 6 is a power source. A 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 alternate long and short dash line, the conductive piece 5a comes into contact with the switch 8 provided on the camera body 1, thereby causing the camera to operate the shooting start button 3. If the button is pressed, shooting is performed, that is, a shooting state in which magnetic information such as image information is recorded on the floppy. The finder 5 is also provided with a working pin 5b. The action pin 5b springs the lock member 9 that is biased to rotate counterclockwise by a spring (not shown) provided in the camera body 1 when the finder 5 is projected from the storage position indicated by the solid line. The lock member 9 is rotated between the double arms 7a of the battery storage lid 7 with the lock arm 9a in the state where the finder 5 is in the projecting position by rotating the lock member 9 in the clockwise direction against the urging force. Hold the state. Therefore, in the photographing state in which the finder 5 is projected, the battery storage lid 7 cannot be opened and the power supply battery 6 cannot be removed.

In the illustrated example, the battery storage lid 7 is configured such that the protruding piece 7b on the opposite side of the double portion 7a is engaged with the inside of the camera body 1 to form the double portion 7a.
Although it is removable by opening and closing the side in the direction of arrow B, the invention is not limited to this, and it may be hinged to the camera body 1 or may be a slide opening and closing type. When the slide opening / closing type is used, the locking member 9 may be locked with a hook. Reference numeral 7c is a handle used to open and close the battery storage lid 7.

If you push down the viewfinder 5 from the protruding position to the storage 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 lock member 9 to release the action on the lock member 9, so that the lock member 9 is rotated counterclockwise by the spring bias to rotate the double portion 7a of the battery storage lid 7. The battery housing lid 7 can be opened and removed by the handle 7c. That is, to remove and replace the power battery 6,
This can be done only in the non-photographing state in which the finder 5 is in the storage position.

As described above, it is possible to completely prevent the power battery from being inadvertently removed during shooting. But if Finder 5
If it is inadvertently pushed down to the storage position during shooting, the same trouble as with the removal of the power supply battery 6 will occur in the above example. This trouble is caused, for example, by providing an electromagnetically-actuated locking member that prohibits the finder 5 from being pushed down while the video floppy is rotating, or by opening the power switch one shooting time after the switch 8 is turned off. It can be easily prevented by using a switch of the switching circuit.

〔The invention's effect〕

According to the still video camera of the present invention, it is clearly recognized that the camera is in a shooting state, and the power supply battery cannot be removed in that state, so it is possible to prevent the occurrence of troubles due to the interruption of the power supply during shooting. Produce an effect.

The related mechanism of the finder and the battery storage lid in the present invention is not limited to the above-mentioned embodiment.
