ABSTRACT:

CROSS-REFERENCE TO RELATED APPLICATIONS
This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 11-174084, filed Jun. 21, 1999, the entire contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
The present invention relates to a camera, and more specifically to a camera equipped with heat insulating means for preventing heat generated by a strobe device from being transmitted to a distance-measuring device.
Conventionally, a strobe device and a distance-measuring device for measuring the distance to an object are disposed with a predetermined distance between them, in order to prevent an error in distance-measuring from being caused by the heat generated by the strobe device.
In the meantime, the technology in the field of the camera has been advanced so as to increase the magnification of zooming; therefore there is an increasing demand for a higher-precision distance-measuring device, and at the same time, a smaller-sized camera.
In a conventional camera, the strobe device and distance-measuring device cannot be arranged to be adjacent to each other, due to the heat generated by the strobe device. Such a fact limits very much the layout design of the devices, and therefore the downsizing of the camera cannot be achieved.
BRIEF SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a camera equipped with a high-precision distance-measuring device, which can be reduced in size and can avoid an error in distance-measuring, which is caused by the heat generated by the strobe device.
In order to prevent the above-described object, there is provided a camera according to the first aspect of the present invention, comprising:
a strobe device;
a distance-measuring device for measuring a distance to an object; and
a heat insulating section provided between the strobe device and the distance-measuring device, so as to prevent heat generated by the strobe device from being transmitted to the distance-measuring device.
Further, there is provided a camera according to the second aspect of the present invention, comprising:
a strobe device;
a distance-measuring device for measuring a distance to an object;
a first wall section provided between the strobe device and the distance-measuring device; and
a second wall section provided between the strobe device and the distance-measuring device, such as to form a predetermined gap with respect to the first wall section.
Further, there is provided a camera according to the third aspect of the present invention, comprising:
a strobe device;
a distance-measuring device for measuring a distance to an object; and
a heat insulating section which forms an air layer between the strobe device and the distance-measuring device.
Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentalities and combinations particularly pointed out hereinafter.
