Abstract: A lens frame holding a taking lens is movably connected to a driving shaft via a connector. A guide member is disposed at a lower portion of the lens frame so as to separate from the connector by about 180 degrees around an optical axis. The guide member is movably attached to a guide rod. A light emitter is disposed on a lateral side of the lens frame so as to separate from the connector by about 90 degrees around the optical axis. The light emitter applies the light to a light receiver of a line sensor confronting the light emitter. The line sensor sends a light-reception signal, which is outputted from the light receiver, to a lens-position controller. Positional information of the taking lens is obtained on the basis of the light-reception signal so that a position of the taking lens is accurately detected.

Abstract: An image server stores volume data including a plurality of tomographic images. A doctor sends transfer request of volume data through a client terminal to the image server when reading an image. Upon receiving the transfer request, a CPU of the image server refers to a doctor information DB based on a doctor ID included in the transfer request to judge a site allowed to be browsed by the doctor who has requested. Upon judging the site allowed to be browsed, the CPU refers to site information preliminarily recorded on each tomographic image of the requested volume data. Thereafter, it is determined whether the doctor who has requested is allowed to browse each of the tomographic images or not based on the site information and the site allowed to be browsed. After judging, the CPU transfers only tomographic images allowed to be browsed to the client terminal as the requester.

Abstract: In a digital camera, a solid state imaging device is used to catch subject light so that an image signal is created. The digital camera contributes to effectively implementing further thinness as compare with the conventional ones. A focus lens is revolved between a position on the optical axis and a saving position coming into a hollow portion beside the CCD solid state imaging device, so that the focus lens comes into the hollow portion at the time of the collapse.

Abstract: A first lens holder is connected with a rotary barrel through a helicoid mechanism, and moves in an optical axial direction when the rotary barrel rotates. A second lens holder is connected with the rotary barrel through a cam mechanism. The cam mechanism is constituted of a cam portion that is disposed on a front end surface of the rotary barrel and cam followers that are disposed on a rear end surface of the second lens holder. The cam portion is formed to have sloped surfaces inclined along a circumferential direction and these sloped surfaces are in contact with the cam followers. When the rotary barrel rotates, the cam followers shift in the optical axial direction along the sloped surfaces, thereby moving the second lens holder back and forth in the optical axial direction.
