Abstract: A camera with a removable imaging lens unit is a small and reliable camera which can prevent electrostatic discharge from causing breakdown or malfunctions. Electrical contact points on a camera body are covered and protected by a mount barrier. When mounting the imaging lens unit on the camera body, a push head is placed in contact with the mount barrier and pushes the mount barrier. After the push head pushes down the mount barrier against the urging force of the spring, electrical contact points on the lens unit are connected with the electrical contact points on the camera body.

Abstract: An artificial crystal double refraction plate is attached to the top of a package having a solid state imaging device chip. The artificial crystal double refraction plate protects an imaging surface and has an optical low-pass effect. An IR cut coating is applied on the surface of the artificial double refraction plate. Another two artificial crystal double refraction plates are arranged separately from the artificial crystal double refraction plate attached to the package. These three artificial crystal double refraction plates achieve desired optical low-pass effects in horizontal and vertical directions.

Abstract: The present invention provides a technique which enables remote operation and a remote-shooting system while watching a monitor display using a compact camera and simple accessories. A transmission unit has a mount connected to a lens unit, a transmission section and a power supply section. A reception unit has a mount connected to a camera body and a reception section. The reception unit is connected to the camera body to make the camera body act as a remote controller for image monitoring, selection of a shooting mode, and release operation and the like, thereby providing a remote-shooting function through communication between the transmission unit and the reception unit.

Abstract: An electronic still camera which photographs an object by image pickup means such as a solid image pickup element or the like and records the video signal of the object into a rotary recording medium such as a magnetic disc or the like. The electronic still camera includes a mechanical shutter and an electronic shutter function to control electrically the accumulation time of the image pickup means and it is adapted such that, when the shutter speed is slower than a predetermined value, it controls a time for exposure to the image pickup means by the mechanical shutter and, when the shutter speed is higher than the predetermined value, it controls the exposure time to the image pickup means by means of the electronic shutter function and also controls the mechanical shutter to remain open at least for the exposure time.

Abstract: An automatic focusing adjusting device for use in a camera is disclosed in which an operation processing on the phase difference detection to be executed when the focusing of an image pickup optical system is detected can be performed by means of an analog signal processing. In the automatic focusing adjusting device, when the distance measurement ranges in a light receiving part of sensor means are specified by operation means, then control means controls charge input preventive means in such a manner that only the signal electric charges that are stored in photoelectric conversion elements forming the light receiving part but belonging to the other distance measurement ranges that the ranges specified by the operation means are prevented from flowing into a readout part in the sensor means, whereby the distance measurement ranges in the light receiving part of the sensor means can be changed.

Abstract: An automatic focussing adjusting device which detects the amount of de-focussing of an image of an object to perform an automatic focussing adjustment of a taking lens of a camera including a zoom lens. The magnification m of a group of magnification varying lenses in the zoom lens is corrected and the amount of movement .DELTA.X of a group of focus lenses necessary for focussing is calculated based on a corrected magnification .alpha..multidot.m, so that a focussing adjustment can be executed. Also, an error in the amount of de-focussing, caused by manufacturing errors in dimensions defining a positional relationship between line sensors and a group of microscopic lenses in a focus detect element is corrected, and based on a correctively calculated amount of de-focussing .beta..multidot..DELTA.P, a focussing adjustment is performed.

Abstract: A method and apparatus for magnetic recording which permits two information signals to be recorded so that they overlay one another. The first and second tracks cross each other without generating crosstalk during reproduction of the two information signals.

Abstract: A rotary magnetic disc device in an electronic camera system, wherein a subject is still-photographed electronically and recorded in a rotating magnetic disc, and the reproducing of an image is carried out by a television system or a printer.In the above-described rotary magnetic disc device, in order to make the magnetic disc lie along a magnetic head, a regulating plate is opposed to the magnetic head, interposing therebetween the magnetic disc.In the rotary magnetic disc device according to the present invention, the regulating plate moves, following the magnetic head, whereby, an urging force rendered to the magnetic disc by the magnetic head is not varied between the inner periphery and the outer periphery of the magnetic disc and remains constant.

Abstract: A method of controlling diaphragm driving in an electronic still camera, wherein a diaphragm is controlled such that an exposure value of a subject on an image forming screen can become a proper exposure value, and a device therefore. In this control of diaphragm driving, the photometric values obtained from every times of photometry are determined to be higher or lower than the proper exposure value. When the photometric values are determined to be higher than the proper exposure value continuously given times, the diaphragm is closed until the photometric values are determined to be lower than the proper exposure value. When the photometric values are determined to be lower than the proper exposure value continuously the given times, the diaphragm is opened until the photometric values are determined to be higher than the proper exposure value.

Abstract: Device for loading or unloading a magnetic disc pack applicable to a magnetic recorder or reproducer in an electronic camera system wherein a subject is electronically still-photographed and recorded in a rotating magnet sheet, and the reproducing of and image is carried out by a television system or a printer.This device for loading or unloading a magnetic disc pack is provided therein with a blocking plate for preventing the double insertion, whereby, even when the magnetic disc pack may be inserted erroneously, the insertion can be blocked by the blocking plate, so that the magnetic head and like are not damaged.

Abstract: An endoscope includes a forceps-control member movably mounted in a forward region of the elongate portion which is adapted to be inserted into a body cavity for selectively projecting and retracting forceps from and into the forward region of the insertion portion and an operating wire having one end connected to the forceps-control member and extending to the manipulator unit through an operating wire guide tube such that the projection and retraction of the forceps is controlled from the manipulator unit through the displacement of the operating wire.

Abstract: The high frequency incising device includes a flexible tubular member secured to a manipulating unit. The tubular member has an open ended tip portion and a pair of longitudinal spaced openings in the wall of the tube. An electrically conductive wire extends through the flexible tube passing outwardly thereof through a forward one of the longitudinal openings and being anchored to the flexible tube at a rearward one of the longitudinal openings. Such anchoring is accomplished by bending the wire toward the tip portion of the tube. A second bend portion in the outwardly exposed wire is directed away from the tip portion such that the outwardly exposed wire takes on the shape of a fan or sector. An opposite end of the wire is connected to an electrically conductive pipe that is movably disposed in the manipulating unit and the tube. An end of the movable pipe that projects beyond the manipulating unit is connected to an anchoring device that is movable with respect to the manipulating unit.
