Abstract: A camera or a remote controller with memory stores pieces of title information which correspond to predefined titles. The title information includes a title number and title display data. The title number indicates a predefined title to be printed together with a frame image on photographic film. The title display data is displayed on a LCD in the same mode as a printing mode. The pieces of title information are sequentially fetched from the memory in response to a title selection operation. The title display data of a fetched piece of title information is displayed on the LCD so that a desired title can be selected.

Abstract: A film cartridge control device is provided for controlling a film cartridge provided with a data disk which rotates in association with a cartridge spool and indicates given information depending upon a position at which the data disk is stopped when a film is completely rewound in the film cartridge. The film cartridge control device includes a drive device that drives and rotates the cartridge spool, a control circuit that performs stop control for causing the drive device to stop the data disk at a predetermined position, and a storage circuit that stores stop control information that indicates that the stop control is being performed. The stop control information is set when the stop control is started and reset when the stop control is finished. The control circuit restarts the stop control after the cartridge spool is rotated by a predetermined amount by the drive device, if the stop control information is set in the storage circuit when the film cartridge control device is started.

Abstract: An electronic still video camera has an electro-developing recording medium and a printer. An optical image is focussed and formed on the electro-developing medium by a photographing lens, and is directly recorded and developed thereon as as a visible image. The recorded image is photoelectrically read by a CCD image line sensor as a series of pixel data, and the series of pixel data is processed to thereby produce a printing data therefrom. A printing is successively made on a paper on the basis of the processed printing data.

Abstract: A vacuum manifold having a rectangular opening with vacuum access bores connected into the rectangular opening for an illumination field to be projected there through. A vacuum manifold is placed between a photosensitive resist covered wafer and a lens element in a photolithographic tool. The relatively high illumination energy in an illumination field used for projecting an image of a reticle onto a photosensitive resist covered wafer often results in ablated, evaporated, and effused material being coated on the lens element. The vacuum manifold placed between the lens element and the photosensitive resist covered wafer creates an airflow for removing debris or contamination preventing coating of the lens surface. This prevents image quality from degradation over time, as well as reduces downtime needed for cleaning or maintenance of the photolithographic tool.

Abstract: The relative positional relationship between a movable member which is moved to prevent image blur and a locking device for locking the movable member is shifted by an elastic force using a spring or the like from the relative positional relationship while image blur is being prevented to the relative positional relationship in which the locking device is able to lock the movable member. As a result, since electric power is not required for the above shift, the shift is possible even if a power supply is used up in a state in which the movable member is not locked.

Abstract: In a flash device arranged to perform flat emission by detecting the intensity of light emission of a discharge tube during process of the light emission and by controlling the intensity of light emission to become almost constant during process of the light emission, the flat emission is adequately performed by varying a detection level for the intensity of light emission.

Abstract: Ruled lines printed on a graph paper g are optically detected by a vertical ruled line reading sensor and a horizontal ruled line reading sensor. Ruled line spacing Dp in a plotter coordinate system P is measured and compared with ruled line spacing Dg in the a coordinate system G of a given graph paper, and the correspondence relationship between coordinate system G of the graph paper and coordinate system P of the plotter is determined. When a drawing command is inputted, a coordinate Zc in the drawing command is treated as a coordinate Zg in the coordinate system G of the graph paper, and this coordinate Zg is converted to coordinate Zp in the coordinate system P of the plotter, using the correspondence relationship. The drawing command is then executed with respect to the converted coordinate Zp. As a result, figures or waveforms that match the ruled lines of the graph paper can be drawn. Ordinary graph paper can be used because the ruled lines are read, contributing to ease of use.

Abstract: According to the improved apparatus for recording images using exposing optics equipped with a dust excluding mechanism which prevents optical paths of light beams from being blocked by dust particles, the dust excluding mechanism has a fan and at least two filters, and at least one of the filters which is provided upstream of an air stream generated by the fan is fitted to be detachable. With the improved image recording apparatus of the invention, not only during scanning exposure, in a standby mode and in a power OFF mode but also during filter replacements, one can prevent the entrance of the dust particles into the duct, thereby ensuring that the light beams issuing from the exposing optics during scanning exposure will not have any part of their paths blocked by the dust particles. As a result, one can record defect-free images of high quality that do not have any density unevenness occurring in the form of streaks due to the dust particles.
