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 an image signal of a subject image on a magnetic recording medium, and more particularly, to an integrated structure of a magnetic recording device and a lens barrel suitable for miniaturization. About.

[0002]

2. Description of the Related Art A conventional electronic still camera includes an imaging unit for photoelectrically converting a subject image obtained through a lens optical system by a solid-state imaging device, a signal processing unit for converting the photoelectrically converted signal into a magnetic recording signal, and a recording unit. It comprises a magnetic recording section for magnetically recording on a medium, and these element units are arranged as in the following two examples.

FIGS. 4 and 5 show a conventional example. FIG. 4 shows an example in which an imaging unit 30 and a magnetic recording unit 31 are arranged side by side. Both are fixed to a main frame 32, and a camera body 33 is attached to the main frame 32. Becomes larger horizontally.

FIG. 5 shows an example in which an image pickup section 30 and a magnetic recording section 31 are arranged and fixed on a main frame 32 in the front-rear direction (depth direction). In this case, the camera has a thick outer shape.

[0005] The location between the upper and lower pivoting fulcrums 34 provided in the two conventional recording apparatus bodies is such that the recording medium accommodating part 35 pivots about the fulcrum 34, and therefore, the other than the fulcrum. It is a dead space where nothing is placed.

[0006]

In the conventional electronic still camera, since the imaging section and the magnetic recording section are separately arranged without being integrated, there is a dead space between the fulcrums and the mounting density is not so high. The camera outline has also increased,
There was a problem that it was not possible to meet the demand for miniaturization.

An object of the present invention is to solve the above-mentioned problems by integrating an image pickup unit and a magnetic recording device main unit, which have relatively inflexible shapes compared to a signal processing unit.
Provided is an electronic still camera that eliminates dead space without deteriorating functions and performance, improves mountability, and enables miniaturization.

[0008]

In order to achieve the above object, the present invention provides a recording medium storage section, a driving section for driving the recording medium to rotate, and a magnetic head for recording or reproducing a video signal on or from the recording medium. A magnetic recording main unit having a magnetic head moving unit, a main body imaging unit including a lens barrel that holds a lens that forms a subject image and an imaging device that converts the formed subject image into a video signal, The main body imaging section is disposed between a rotation fulcrum provided on the magnetic recording main body section for rotating and opening and closing the recording medium storage section and opposite to the rotation opening and closing side of the recording medium storage section, An electronic still camera is provided, wherein the main body of the magnetic recording device and the main body imaging unit are configured to be integrated.

[0009]

According to the structure of the present invention, the mountability of the electronic still camera can be improved and the size of the electronic still camera can be reduced.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1, 2 and 3 are schematic views of the configuration of the embodiment of the present invention.

FIG. 1 is an arrangement diagram of element units showing an embodiment of the configuration of an electronic still camera according to the present invention. In the figure, a main body imaging unit 1 for photoelectrically converting a subject image obtained through an optical system by a solid-state imaging device, a signal processing circuit unit 2 for processing a signal obtained by the photoelectric conversion into a magnetic recording signal, and magnetic recording on a recording medium 4 The main body image pickup unit 1 is disposed between a rotation fulcrum 6 provided on the magnetic recording main body unit 3 for rotating the magnetic recording medium storage unit 5. ing. The main body imaging section 1 and the magnetic recording main body section 3 are integrated to form a main body 7.

The camera body 8 includes these components, and components including a battery unit, a finder, and other signal processing circuit units, which are not described here.

FIG. 2 is a front view of the configuration of the main body 7 in which the main body imaging section 1 and the magnetic recording main body section 3 of the present invention are integrated.
In the figure, a spindle motor 10 of a rotation drive unit for rotating a magnetic sheet 9 of a magnetic recording medium, and a magnetic head 1
The magnetic head 11 comprises a screw shaft 12 having a screw portion for moving the magnetic sheet 1 in the radial direction of the magnetic sheet 9 and an engaging portion 13 fixed to a carriage 14 for receiving the screw portion.
Is moved in the radial direction of the magnetic sheet 9. A feed motor 15 for controlling the rotation of the screw shaft 12 is attached to the magnetic recording unit, and FIG. 3 is a sectional view taken along the line AA of FIG. As shown in the figure, a lens group 17 and a lens barrel 18 for forming a subject image of the main body imaging unit 1 on the solid-state imaging device 16, a positioning plate 19 for positioning the solid-state imaging device 16, and a solid-state imaging device thereon The figure shows that a substrate 20 and the same circuit component group 21 are formed, and these are provided between the rotation fulcrums 6 of the recording medium storage unit 5.

[0014]

As described above, according to the configuration and method of the present invention, since the components of the imaging unit are arranged between the rotation fulcrums of the recording medium storage unit 5 of the main body 7, the function of the magnetic recording unit is achieved. The imaging unit and the magnetic recording unit can be integrated without deteriorating the performance, and the size of the element unit can be reduced without the need for a mounting frame or the like, the mountability is improved, and the camera can be downsized.

Further, by arranging the image pickup section between the fulcrums, the image pickup lens section can be arranged almost in the center or in the vicinity of the camera, and the camera design is well balanced.
