Abstract

PURPOSE:To provide an electronic still camera whose miniaturization is effectively realized. CONSTITUTION:The camera is provided with a solid-state image pickup element 1 and a recording medium 3 such as solid-state memory or a hard disk. The solid-state image pickup element 1 or a board 5 on which the solid-state image pickup element 1 is packaged are assembled to a support member 2 for the recording medium 3 especially. Miniaturization is effectively realized by adopting the configuration that the solid-state image pickup element 1 or the board 5 on which the solid-state image pickup element 1 is mounted is directly assembled to the support member 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic still camera for recording a signal read from a solid-state image pickup device in a recording medium such as a solid-state memory or a hard disk.

[0002]

2. Description of the Related Art A conventional general electronic still camera converts a subject light passing through a photographing lens into an image information signal,
The image information signal is recorded on a recording medium. Therefore, this type of camera is provided with a solid-state image sensor at the rear of the taking lens unit and a holding member for a recording medium that records the image information signal output by the solid-state image sensor. Some of the electronic still cameras include a finder unit for confirming the shooting range, a signal processing board, a battery or a strobe.

[0003]

However, in such a conventional electronic still camera, the solid-state image pickup device unit, the recording medium unit, and other units or parts are separately assembled with the frame as a support base. In such a structure in which the units are separately assembled through the frame, each unit is partitioned by the frame, which is extremely disadvantageous in improving space efficiency and downsizing the camera.

In view of the above situation, it is an object of the present invention to provide an electronic still camera that can be effectively miniaturized.

[0005]

An electronic still camera according to the present invention has a solid-state image sensor and a recording medium such as a solid-state memory or a hard disk. Particularly, a holding member for the recording medium includes a solid-state image sensor or a solid-state image sensor. The configuration is such that a substrate on which a solid-state image sensor is mounted is assembled.

[0006]

According to the present invention, the solid-state image pickup device or the substrate unit on which the solid-state image pickup device is mounted as described above is directly assembled to the holding member of the recording medium, thereby effectively reducing the size. be able to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an electronic still camera according to the present invention will be described below with reference to FIGS. FIG. 1 shows a configuration example of an electronic still camera to which the present invention is applied.
In the figure, reference numeral 1 is a solid-state image pickup device composed of a CCD (Charge Coupled Device) or the like, and 2 is a holding member for a recording medium described later, which is provided with an assembly portion 2a of the solid-state image pickup device 1. 3 is a recording medium such as a solid-state memory or a hard disk, 4 is a connector for exchanging data and supplying power between the recording medium 3 and the camera, 5 is a signal processing circuit, a controller for system control, and the solid-state imaging device 1 It is a circuit board on which the like is mounted.

Further, 6 is a taking lens unit, 7 is a finder unit having a finder and a light projecting / receiving device for autofocusing, 8 is a strobe unit, 9 is a rechargeable battery detachable from the camera, and 10 is a front cover. And has an insertion opening 10a for the recording medium 3. Further, 11 is a release button which is an operation switch for generating a video recording trigger signal, and 12 is a rear cover.

FIG. 2 shows the solid-state image pickup device 1 and the holding member 2.
Shows the connection relation of. The solid-state image pickup device 1 is adapted to be fixed with screws or an adhesive or the like at 2 to 4 places in the assembly portion 2a of the holding member 2. Further, the circuit board 5 is arranged in parallel to the holding member 2 and on the front side thereof, and is connected to the solid-state imaging device 1 through soldering. On the other hand, the circuit board 5 is connected to the connector 4 at its end 5a.

Here, FIG. 3 shows an example in which the circuit board 5 on which the solid-state image pickup device 1 is mounted is fixed to the holding member 2. In this example, the circuit board 5 is fixed to the assembly portion 2b of the holding member 2 and positioned by the shaft portion 2c. In the example shown in FIG. 1, a thin rechargeable battery 9 is arranged on the lower surface of the camera, but in FIG. 3, the left side of the lens barrel of the taking lens unit 6 is seen from the front of the camera. It is also possible to enhance the holdability by arranging the rechargeable battery 9'in the front and attaching a proper grip shape to the front cover 10 (see FIG. 1).

As described above, in the electronic still camera of the present invention, the solid-state image pickup device 1 or the circuit board 5 on which the solid-state image pickup device 1 is mounted is mounted via the assembling part 2a, the assembling part 2b or the shaft part 2c. It is directly attached to the holding member 2 of the recording medium 3. That is, the solid-state image pickup device unit and the recording medium unit are not separately supported by the frame and assembled, but are integrally assembled to the holding member 2 as in the above-described embodiment, so that the space is effectively used. be able to.

In the above embodiment, an example in which the circuit board 5 is composed of one sheet has been described. However, in the case of a plurality of boards, it is possible to obtain high space efficiency by arranging them in parallel with each other. it can. Further, in the above embodiment, the recording medium 3 is arranged perpendicularly to the optical axis to be thin, but the recording medium 3 may of course be arranged parallel to the optical axis. Further, for example, when an optical filter such as an infrared cut filter is required, the optical filter and the solid-state image pickup device 1 can be fixed together with the holding member 2. It is possible to obtain the same operational effect as.

[0013]

As described above, according to the present invention,
Since the solid-state image sensor or the substrate unit on which the solid-state image sensor is mounted is assembled to the holding member of the recording medium, it is possible to effectively reduce the size and thickness of the camera, which is excellent in portability. It is possible to realize a camera of this kind.
