This invention relates to cameras operable to select one film supply system from either a normal wind-up system or a preparatory wind-up system. The camera has a selector switch for selecting one of the film supply systems, and an inhibiting means for inhibiting that the two systems are applied to one film by the switch, a write means for recording selected information onto a film or a storage device provided in the cartridge, and a read means for reading the selected information and the frame information written in the device. The switch selects a film supply system which is indicated by the selected information read out from the device of the loaded film by the read means. Additionally, a film supply means is provided for preparing and supplying the film in accordance with the frame information read out by the read means. The film supply means can wind up the film to supply even when either of the two film supply systems is set. The selection of the film supply system can be changed by the switch only before the first frame is photographed. A counter is provided for inhibit that the first frame of the film is supplied to the photographing position more than predetermined times in response to the change in the film supply system selected by the switch.

There is disclosed a camera equipped with a mode setting device which counts the number of uses of each of plural modes, and sets the most frequently used mode as the initial mode. At the phototaking operation, the camera is set at such most frequently used mode. The above-mentioned plural modes can be plural exposure control modes, focal length control modes, photographing magnification setting modes, self-timer modes, automatic exposure value correcting modes, or alarm modes.

A film feeder for a camera comprises a feeding out mechanism for feeding out film of a film cartridge wound around a spool shaft, by rotating the spool shaft of the loaded film cartridge; a winding up mechanism for driving a wind up spool to wind up around the wind up spool the film fed out of the film cartridge; a roller provided between the loaded film cartridge and the wind up spool, which is driven by the driving power of a motor to feed the film fed out by the feeding out mechanism and guide the film to the wind up spool; and a driving power transmission mechanism for transmitting the driving power of the motor to the roller until the film is wound around the wind up spool and thereafter cutting off the transmission of the driving power to the roller.

A camera is provided in which when a film unit exposed up to a midroll frame in one wind mode is reloaded, the exposure of the film unit can be continued in another wind mode without causing double exposure. The camera discriminates whether the next frame adjacent to an exposed frame which has just been exposed is an unexposed frame or an exposed frame. If the next frame is an exposed frame, the operation of rewinding film into a cartridge is performed to thereby render further photographing impossible. Thereby, when a film unit exposed up to a midroll frame in one wind mode (e.g. the ordinary wind mode) is loaded into the camera, the continuation of the exposure of the film unit can be effected in the other wind mode (e.g. the prewind mode) without causing double exposure. A camera is further provided which utilizes two or more recording areas prepared in a data recording portion provided to a film leader portion, and in which data is recorded on a recording area different from that in a previous recording operation upon each rewind operation, thus eliminating the problem caused by overwritten data.

A retrieval support system includes a database which stores commodity image data; a retrieval unit which acquires commodity image data having image characteristic information which is the same as or similar to image characteristic information indicating a characteristic in an image of input image data, from the database, with respect to the input image data; and a condition setting unit which sets a retrieval condition including at least one of time information relating to time, place information relating to places and occasion information relating to occasions. The retrieval unit performs retrieval of the commodity image data based on the retrieval condition set by the condition setting unit. The commodity image data acquired by the retrieval unit and information relating to a commodity different from a commodity corresponding to the commodity image data are output together.

An exposure method enabling deformation occurring in a unit exposure field to be measured rapidly and accurately and enabling a plurality of patterns to be superimposed on a substrate with high accuracy. The exposure method of the present embodiment for exposing a bright-dark pattern on the substrate using a projection optical system includes a position detection process for detecting the positions of a plurality of position detection marks, relative to a substrate-in-plane-direction of the substrate, arranged in at least one functional element in a unit exposure field of the substrate, a deformation calculation process for calculating the state of deformation occurring in the unit exposure field based on information related to the positions of the position detection marks obtained in the position detection process, and a shape modification process for modifying the shape of the bright-dark pattern to be exposed on the substrate based on the deformation state obtained in the deformation calculation process.

Target 1 that is arranged in the disc direction is sprayed from nozzle 2 that has a slit-shaped aperture. Target 1 is conveyed on a gas stream. He gas is used in this example. Nozzle 2 may be vibrated by a piezo apparatus to spray disc-shaped target 1. Target 1 that is sprayed from nozzle 2 reaches the irradiation position of laser light with its direction unchanged since the exterior of nozzle 2 is maintained in a high vacuum. Synchronized with delivery of target 1, pulse laser light 5 from Nd:YAG light source 4 is focused by lens 3 and irradiated onto target 1. The spot diameter of the laser is the same 1 mm diameter as that of target 1. The thickness is not more than 1000 nm. Therefore, virtually the entire target is converted into plasma, debris generation is inhibited and the conversion efficiency is elevated.

A device (e.g., a camera) loaded with a film unit operates to detect a characteristic of the film unit, such as the state of an information part of the film unit. The detection result is used as a basis to control the performance of a further operation, such as a phototaking operation or a state-setting operation for the information part.
