Abstract

PURPOSE:To prevent an unexpected ejecting operation of a recording medium being photographed and recorded by placing a lens cover at an opening position, photographing thereafter, and preventing the recording medium for being detached by the lens cover in the period from the completion of the photographing to the lens cover is closed. CONSTITUTION:An eject switch 5 provided with a lock mechanism is slidably disposed in a recessed part provided on a sliding surface of a lens cover at the upper part of a camera main body 1. A photographer operates an eject switch 5, opens a bucket 6 and charges a magnetic disk. Immediately before an object to be photographed is photographed, a lens cover 3 is slided, a photographing lens 2 is opened and a release button 4 is pressed to perform a photographing. Almost at the same time, a recording of the object to be photographed as an electric signal is carried out on the magnetic disk, the lens cover 3 is slided and is photographing lens 2 is closed to complete the photographing. Accordingly, during photographing and recording, the eject switch 5 is covered by the lens cover 3 and cannot be operated by the photographer.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a still image recording device such as an electronic still camera, and relates to an electronic still image recording device equipped with a mechanism to prevent ejection of a recording medium during shooting. This relates to a type still camera.

(Prior art) In recent years, imaging devices such as solid-state image sensors and image pickup tubes are combined with recording devices that use recording media such as magnetic materials and memory to take still photographs of objects purely electronically, and electricity is transferred to the recording medium. Electronic still camera systems have been developed that record signals and reproduce images using a separate television system or printer.

In such an electronic still camera, a recording medium is loaded into a slot provided in the camera body that can be opened and closed, and a still photographed subject is recorded on the recording medium. Furthermore, since the recording medium in the electronic still camera is not exposed to light unlike conventional silver halide film, it is possible to freely take it in and out of the camera even after half way through the recording.

(Problem to be solved by the invention) In an electronic still camera such as the one described above, the recording medium can be taken in and out at any time other than when shooting or recording, but if the eject switch is touched during shooting or recording, the packet is released. Therefore, the present invention provides an electronic still camera in which the recording medium during photographing and recording can be prevented from being inadvertently ejected using a simple mechanism. It is something.

(Means for Solving the Problems) According to the present invention, the lens cover is formed integrally with the camera body so that the photographing lens can be placed in two positions, one for opening and one for closing.

In an electronic still camera that records a photographed subject as an electrical signal on a recording medium using a combination of an imaging device such as a solid-state image sensor or an image pickup tube and a recording device using a recording medium such as a magnetic material or a memory, the lens cover is A means is provided to prevent the recording medium from separating from the camera body when the photographing lens is placed in the open position, and furthermore, for this purpose, the eject switch is covered by the lens cover and is in a position where it becomes inoperable. The eject switch has been completely removed.

(Function) In the electronic still camera according to the present invention, the lens camera prevents the recording medium from detaching from the time when the lens cover 2- is placed in the open position, the photograph is taken, and the lens cover is closed after the photograph is completed. Therefore, it is possible to prevent the recording medium from being ejected during the recording of electrical signals onto the recording medium, which is carried out almost simultaneously with photographing, and thereby preventing the recording medium from not being photographed or from performing incomplete recording.

(Example) Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram of an electronic still camera equipped with a mechanism for preventing the ejection of a recording medium during photographing and recording according to the present invention. In the electronic still camera of the present invention, a U-shaped lens cover 3 that covers a photographic lens 2 is attached to the camera body 1 so as to be slidable in the left-right direction. The photographic lens 2 is configured to have two positions: an open position and a closed position. A packet 6 for loading a magnetic disk as a recording medium is provided on the front side of the camera body 1.
The locking mechanism of the packet 6 is, for example, as shown in FIG. 2, in the packet 6 which is pivoted by hinge parts 7 provided at both ends of the lower part of the packet, a notch 11 of a lock lever 9 provided at the upper end of the packet 6 is used. The eject switch 5 is locked by fitting the eject switch 5 with the protrusion 8 of the eject switch 5, and the eject switch 5 is held at the lock position by a spring 10 whose other end is fixed to the camera body.

Then, by sliding the eject switch 5 in the direction indicated by the arrow, the fitting portion between the protrusion 8 and the lock leno z-9 is disengaged, and the /Z socket 6 is opened.

Furthermore, when the nokkerato 6 is closed, the protrusion 8 of the eject switch 5 and the tip of the lock lever ζ-9 come into contact with each other, and by further pushing the lock lever 9, the lock lever 9 is moved downward by the inclined surface of the tip of the lock lever 9. When bent, the protrusion 9 fits into the notch 11 and is locked.

The eject switch 5 equipped with the above-mentioned locking mechanism is slidably installed in a recess provided in the lens cover sliding surface at the top of the camera body 1, and the slide cover 3 slides above the eject switch 5. be able to.

Furthermore, the eject switch 5 is installed at a position where it is exposed when the photographic lens 2 is closed by the lens cover 3, and is covered by the lens cover 3 when the photographic lens 2 is opened.

Next, explaining the photographing procedure, the photographer operates the eject switch 5 to open the packet 6 and load the magnetic disk. Then, just before photographing the subject, slide the lens cover 3 to open the photographic lens 2, and press the release button 4.
Press to take a picture.

Almost at the same time, the subject is recorded on the magnetic disk as an electric signal, and the photographing is completed by sliding the lens cover 3 to close the photographing lens 2. Therefore, in the electronic still camera of the present invention, the eject switch 5 is covered by the lens cover 3 during photographing and recording, and cannot be operated by the photographer.

Further, the ejection prevention device during photographing according to the present invention is not limited to simply making the eject switch 5 inoperable when the lens cover 3 is in the open position, but is also capable of directly preventing the packet itself from being opened by opening the cover 3. You can. Furthermore, the recording medium is not only a magnetic disk, but is also effective for other recording media such as semiconductor memory,
The packet locking mechanism is also not limited to the one described in this specification.

(Effects of the Invention) According to the present invention, after the lens cover is placed in the open position,
Since the lens cover prevents the recording medium from coming off until it is closed, it is possible to prevent the recording medium from coming off during shooting and recording, thereby preventing incomplete recording.
Furthermore, this objective can be achieved by a cheap and simple mechanism.
