In a sliding door apparatus, a first entrance is opened and closed by a first door, and a second entrance that faces the first entrance is opened and closed by a second door. Imaging means that captures images across a space between the first entrance and the second entrance is disposed beside the space. An image processing and determining portion determines presence or absence of an obstruction inside the space based on image data from the imaging means.

A fingerprint image pickup device includes a light source that emits a light for transmission through a fingertip portion having a fingerprint to be photographed, an image pickup unit that picks up the light from the light source and transmitted through the subject to acquire a fingerprint image in which convex and concave parts of the fingerprint are dark and bright, respectively, and an optical system that images the light transmitted through the fingertip portion on the image pickup unit. The optical system is arranged so that a distal side of the fingertip portion is tilted at a predetermined angle, farther away from the optical system thank an opposite sides with reference to a position at which a ventral side of the fingertip portion contacts a face orthogonal to an optical axis of the optical system.

In an elevator apparatus, a guide rail has a plurality of unit rails that are vertically connected to each other. A car is provided with a rail joint detecting device mounted on the car, for detecting the presence/absence of a joint between each of the unit rails. The rail joint detecting device has a joint detecting portion for optically detecting the presence of the joint; and a joint determining portion for determining the presence/absence of the joint based on information from the joint detecting portion. Information on the presence/absence of the joint is outputted from the joint determining portion to a car position correcting circuit. In the car position correcting circuit, information on the position of the car is corrected based on the information on the presence/absence of the joint.

An irregular pattern detector includes a first optical system, a transparent light guide body and a second optical system. The first optical system has a light source. The transparent light guide body has an incident face receiving incident light from the light source of the first optical system, a detection face facing the incident face for placing of a subject having an irregular pattern, a curved surface reflecting scattered light from the detection face, an optical absorbing face facing the curved surface and having an opening outputting light reflected from the curved surface. The second optical system, such as an imaging lens, guides the light from the opening of the optical absorbing face of the transparent light guide body to a camera device. This irregular pattern detector can be scaled down, and can produced precise images without any deformation.
