摘要： In a picture processing apparatus, respective results of subtraction calculation between the relevant pixel and the reference pixels are obtained by a subtraction arithmetic circuit. The resultant differences are converted nonlinearly by a nonlinear conversion circuit, and thereafter a summation calculation of these resultant differences are performed by a first addition arithmetic circuit. The obtained result is added to data of the relevant pixel by a second addition arithmetic circuit; thereby achieving MTF correction. By adequately selecting the input-output characteristic of the nonlinear conversion circuit, a stable contour line enhancement is achievable even when noise is present in the picture signal.

摘要： A rotary head type magnetic recording and reproducing system of helical scan type is disclosed using a tandem type tape cassette accommodating coaxial supply and take-up reels. At the time of tape loading, a rotary ring carrying a tape take-out post is rotated along the outer periphery of a cylinder including a rotary magnetic head assembly, and with this rotation the take-out post contacts the magnetic tape which is drawn out of the cassette and passed round the cylinder at a predetermined angle.

摘要： The disk centering device of the invention includes: a turntable for retaining an information recording disk which has a center hole and is placed on a placing surface so that the disk can rotate around a rotation axis thereof; and a centering unit including a plurality of centering portions coming into contact with a periphery of the center hole and a plurality of resilient portions, each of which is connected with a corresponding one of the plurality of centering portions for supporting the centering portion so that the centering portion can be resiliently displaced in a radial direction of the information recording disk. In the disk centering device, the turntable includes regulating faces for regulating positions of the centering portions in a state where the centering portions are resiliently displaced in the radial direction as a result of a contact between the centering portions and the regulating faces, and each of the centering portions is in contact with the periphery of the center hole at a disk contact part which is located at a position more distant from the resilient portion than the regulating face.

摘要： The device includes a record paper conveying device which rotates around a record paper carrier body to convey a paper sheet around the carrier body by gripping the leading edge of the paper sheet. In this arrangement, the carrier body, against which a recording head abuts during a recording operation, is rotated following the movement of the paper sheet by a friction force between the platen part and the recording paper sheet. In one embodiment, the carrier body is stationary, and accordingly, the conveying speed of the record paper sheet is determined only by the drive speed of the conveying device so that the record paper sheet can be precisely conveyed.

摘要： According to the present invention, an apparatus for optically performing recording of information and/or reproduction of information for an optical disk having a recording surface is provided. The apparatus includes: an optical pickup for forming a first light spot on the recording surface; a tilt sensor, arranged to be transported with the optical pickup, for detecting a tilt of the optical disk with respect to an optical axis of the optical pickup by forming a second light spot on the recording surface; and a tilt compensating mechanism for angularly adjusting the optical pickup to eliminate the tilt. In this apparatus, the second light spot is formed at such a position that a line between the first and second light spots is inclined to a direction perpendicular to the radial direction of the optical disk. This prevents the second light spot from entering mirror regions having no pits or no grooves, even when the first light spot is located on the inner circumference of an information recording region having pits or grooves or on the outer circumference of the information recording region.

摘要： An image transmitting element connecting a display device accommodated in a display casing and an image output element accommodated in a main body casing with each other are composed of a sheet-shaped flexible cable having a wiring pattern. The image transmitting element is partly wound in a spiral between a fixing portion on the display casing side and a fixing portion on the main body casing side. The rotational axis of a hinge unit is disposed in the vicinity of the rear end of the main body casing. Owing to this construction, the motion of the image transmitting element which occurs due to the pivotal motion of the display casing is limited to a small space in which the wound portion of the image transmitting element is disposed whereby the image transmitting element is accommodated in the small space.

摘要： A tape wrapping mechanism for a rotary head type VTR wherein a tape pulling post is provided on a rotary ring mounted rotatably on the outer periphery of the cylinder, a rotary ring is rotated so that the post rotates along the outer periphery of the cylinder to pull out the tape from the cassette and wrap it around the cylinder and the rotary force of the rotary ring is such that, when the magnetic tape is wrapped at a predetermined wrapping angle, a pinch roller is automatically pushed toward the capstan with the tape therebetween. With this mechanism, a state capable of recording and reproduction is realized and the abutment of the pinch roller against the capstan is automatically released by a reverse rotation of the rotary ring when switching from the recording-reproduction state to the stop state.
