Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electronic camera, and more specifically to an electronic camera that can be mounted with a zoom lens having a high magnification while being small and thin.
[0002]
[Prior art]
Since there are many opportunities for electronic cameras to be taken outdoors, such as travel, it is an important requirement that they are small in size, have good portability, and can be photographed and reproduced under various conditions. Therefore, recent digital still cameras and digital video cameras tend to be flat as a whole. A single focal point is used for the photographing lens.
[0003]
However, the conventional one is not easy to use, and as a solution to this problem, a mirror is arranged in the photographic optical system and the optical axis is bent at a right angle so that the zoom lens can be used while being flat. (For example, 1996 Patent Application Publication No. 032841) and a configuration that enables photographing at various angles by rotating the imaging lens (1996 Patent Application Publication No. 2005022) are proposed. ing.
[0004]
[Problems to be solved by the invention]
However, in the conventional example described in Japanese Patent Application Publication No. 32841, there is no auxiliary light source such as a strobe, so that photographing cannot be performed in a dark environment. Also, you can rotate the objective lens and take a picture of the back, but this is not convenient.
[0005]
In the conventional example described in Japanese Patent Application Publication No. 205022, the lens unit is rotatable, and it is difficult to secure a space for incorporating the zoom lens into the lens unit while maintaining portability. It is.
[0006]
The power source of the electronic camera is usually a battery. However, since the battery is relatively cold, it is preferable to provide some cold protection means or heating means. However, providing these means should not increase power consumption.
[0007]
An object of the present invention is to provide an electronic camera that solves such problems.
[0008]
That is, an object of the present invention is to provide an electronic camera that can be mounted with a high-power zoom lens while being small and thin.
[0009]
It is another object of the present invention to provide an electronic camera that can keep a power supply battery warm without special power consumption.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0014]
1 and 2 are external perspective views of a first embodiment of the present invention, and FIG. 3 is a cross-sectional view. Reference numeral 10 denotes a substantially box-shaped camera body. Reference numeral 12 denotes an objective lens unit that is attached to the side surface of the camera body 10 so as to be rotatable about a laterally extending axis. The objective lens unit 12 includes an objective lens 14, and a barrier opening / closing knob 16 is provided on the peripheral surface. When the barrier opening / closing knob 16 is raised, the barrier 18 (FIGS. 3 and 4) closes the opening outside the objective lens 14, and the barrier 18 opens the opening outside the objective lens 14 when lowered. Opened. Reference numeral 20 denotes a strobe Fresnel lens. Reference numeral 22 denotes a card slot (lid) into which the memory card 24 is inserted.
[0015]
Reference numeral 26 denotes a release button. When this button is pressed, an electric image signal of the subject image is recorded in the memory card 24 to which the subject image is mounted.
[0016]
Reference numerals 28 and 30 denote zoom buttons. When the button 28 is pressed, the photographing lens shifts to the tele side, and when the button 30 is pressed, the photographing lens shifts to the wide side. 32 is a display panel for displaying various count values, strobe status, remaining battery level, and the like, 34 is a liquid crystal display panel serving as a finder and playback image display display means, and 36 is playback, erase, frame advance, return, protect, etc. A reproduction processing button 38 for the operation, 38 is a selection button for operations such as exposure mode, self-photographing and exposure correction, 40 is a strobe on / off switch, and 42 is a finger pad.
[0017]
As can be seen from FIG. 3, a zoom lens unit 44 extending laterally from the objective lens unit 12 is accommodated in the camera body 10. The zoom lens unit 44 is rotatable within the camera body 10 around the optical axis direction of the zoom lens unit 44. A mirror 46 rotates the optical axis from the objective lens 14 toward the zoom lens unit 44 at a substantially right angle.
[0018]
48 is an optical low-pass filter, 50 is an image sensor, and 52 is a substrate on which the image sensor 50 is fixed. Reference numeral 54 denotes a flexible printed circuit board, which has a sufficient length so that circuit connection is not hindered by the rotation of the image sensor 50.
[0019]
Reference numeral 56 denotes a heat radiating plate for radiating heat generated by the image pickup device 50. The heat sink 56 is made substantially circular so that the intended purpose can be achieved even when the image pickup device 50 (ie, the zoom lens unit 44) rotates. is there.
[0020]
58 is a thin plate that prevents the deformation of the zoom lens unit 44 when the card 60 is inserted, and 62 is a battery.
[0021]
FIG. 4 is a longitudinal sectional view of the objective lens unit 12 as viewed from the line IV-IV in FIG. Reference numeral 64 denotes a strobe reflection shade, 66 a strobe circuit, 68 a strobe circuit printed circuit board, and 70 a strobe main capacitor.
[0022]
FIG. 5 is a longitudinal sectional view taken along line VV in FIG. 72 is a liquid crystal display element, 74 and 76 are printed circuit boards, and 78 is a mounting circuit of this camera.
[0023]
FIG. 6 is a cross-sectional view of the objective lens unit 12 as seen from line VI-VI in FIG. As described above, when the objective lens unit 12 is rotated with respect to the camera body 10, the zoom lens unit 44 is also rotated together. Therefore, the flexible printed circuit board 54 has a length as shown in FIG. A number of folds are formed with a margin.
[0024]
【The invention's effect】
As can be easily understood from the above description, according to the present invention, since the overall shape is flattened, portability is improved. By arranging a mirror behind the objective lens and bending the optical axis at a substantially right angle to guide it into the camera body, a high-magnification zoom lens can be used even when flattened. Since the zoom lens unit and the image sensor can be rotated together, photographing can be performed regardless of the rotation angle of the objective lens. By attaching a strobe to the objective lens, it is possible to shoot with a strobe regardless of the angle of the objective lens. By disposing the memory card in front of the zoom lens unit and the liquid crystal display means behind the zoom lens unit, the volume can be reduced. Since the battery chamber is arranged right next to the heat radiating plate of the image sensor, the battery is heated by the image sensor, and the life of the battery is extended even in a cold region. In particular, by disposing a battery in the grip portion, it is warmed by gripping with a hand from the outside, and heated inside by heat radiation of the image sensor on the inside, which is particularly effective in a cold region.
