摘要:
An object follow-up mechanism, installed in a camera, which allows the camera to follow movement of a main object to be photographed. The mechanism includes an image detection device for taking an image into a photographing visual field and for extracting a feature of the image; an image recognition device for recognizing a possible candidate region, on which the main object locates, on a basis of the feature; a display device for displaying the candidate region(s); a main object region selection device for selecting at least one candidate region from the displayed candidate region(s) as a main object region in which the main object is present; and a main object region storing device for storing the feature extracted by the image detection device as a feature standard with respect to the image in the main object region thus selected.

A defocus amount of an object is detected by a focus detection unit of a camera, whereby a defocus velocity is calculated according to the detected amount. An average velocity is calculated using a plurality of defocus velocities and then a smoothing velocity is calculated, whereby a reversed position of a velocity direction is detected using the data. An average velocity, a smoothing velocity, and the time of a velocity direction reversed are calculated, whereby a correction velocity is obtained according to the calculation. A driving amount of lens is calculated according to the calculated correction velocity, whereby the photographic lens is driven by the lens driving device so as to follow the moving of an object.

A displacement detector has a contact sensor incorporating a differential transformer and a circuit for adjusting the amplitude of the driving signal for driving a differential transformer of the sensor by feeding back as a standard signal the driving signal through an amplifier and an AC-DC converter as a standard signal. The sensor has a housing containing a mobile member. The mobile member has a shaft with a hole. An outer tubular body of a linear bush and a ball guide each have a hole, and a pin is inserted through these holes movably in the direction of movement of the mobile member such that the rotation of the mobile member is prevented.

A tray unit is moved into a housing or partially pulled out from the housing by a horizontal motor provided in the housing. Since the tray unit can load a plurality of cassettes, the weight of the unit is largely changed in accordance with the number of loaded cassettes. The horizontal motor must be controlled by accurately detecting the moving position of the tray unit. The rotation of the horizontal motor is transmitted to a rotary member. The rotation of the rotary member is associated with a pulse detecting element provided on a printed circuit board for tray position detection. The moving position of the tray unit is detected by counting pulses obtained from the pulse detecting element in accordance with the rotation of the rotary member.

A cleanser feeding mechanism has a cleanser housing portion, a cleanser feeding member for feeding a cleanser housed in the cleanser housing portion, and a synchronous motor for applying a drive force to the cleanser feeding member, and feeds and amount of cleanser corresponding to the number of revolutions of the synchronous motor. A cleanser feeding amount-setting unit sets an amount of cleanser to be fed from the cleanser feeding mechanism. A driving unit applies an AC source voltage of an AC power source to the synchronous motor. A counter counts the number of cycles of the AC source voltage from a timing at which the AC source voltage is applied to the synchronous motor. A reference cycle number-setting unit sets a total cycle number of the AC source voltage which corresponds to a cleanser amount set by the cleanser feeding amount-setting unit. A motor controller compares a count output from the counter with a total cycle number from the reference cycle number-setting unit and stops application of the AC source voltage to the synchronous motor when the count output and the total cycle number coincide with each other.

A tilt stand having a mounting surface and holes for mounting a drum are formed by one normal-feed press working. The holes for mounting the drum are formed by vertical punching. The respective holes are rectangular holes, each of which has one side equal to the diameter of a shaft or the diameter of a screw in the direction of Y. The hole into which the shaft is inserted has the other side in the direction of X which is determined such that the side is in contact with the shaft inserted into the hole in the direction perpendicular to the mounting surface at the obverse surface and the reverse surface of the mounting surface. The drum has a structure in which the shaft projects from the bottom and is positioned with respect to the mounting surface by inserting the shaft into the mounting hole. Three screw holes are formed near the shaft of the drum. The mounting angle of the drum with respect to the mounting surface is determined by the use of the mounting holes corresponding to these screw holes. Therefore, this can reduce the number of processes and the load of a press machine and increases the strength of a base without degrading the mounting accuracy of the drum and the accuracy of the linearity of a lead.

A medical tube clamp wherein first and second plate parts including, on opposing surfaces, compressive protrusions for closing a medical tube are provided with a pair of side walls on both sides projecting from one toward an other of the plate parts, and are also provided with a central guide protrusion projecting from the other toward the one of the plate parts. Both sides of a tip portion of the central guide protrusion make sloping guide surfaces projecting toward a center. When the plate parts are displaced relative to each other so as to become closer, lateral displacement of them is corrected by a slide of the pair of side walls and the sloping guide surfaces, and the central guide protrusion is inserted between the pair of side walls.
