    • It is intended to provide a swash plate type continuously variable transmission capable of automatically affording a lock-up state in which second distributing valves are stopped at their stroke mid-point to cut off motor ports when a motor swash plate stands upright, even without using any special interlocking mechanism. Second distributing valves for bringing motor ports of motor cylinder bores into communication with a high-pressure oil path and a low-pressure oil path selectively in an alternate manner are arranged in parallel with the axis X of a cylinder block; a valve swash plate for reciprocating the second distributing valves is integrally combined with a motor swash plate on the same slant plane; and the motor ports are formed so as to be controlled selectively by the second distributing valves at respective positions 90.degree. out of phase in the circumferential direction of the cylinder block 4 with respect to the corresponding motor cylinder bores, the second distributing valves being stopped at their stroke mid-points when the motor swash plate stands upright. In a swash plate type hydraulic unit for use as a swash plate type oil-hydraulic pump or motor, it is intended to attain the reduction in radial size of the hydraulic unit while ensuring a sufficient plunger stroke.

    • In a hydrostatic continuously variable transmission, a pump cylinder of a swashplate type hydraulic pump is integrally and coaxially coupled with a motor cylinder of a swashplate type hydraulic motor. A number of distributor valves are radially arranged for reciprocal movement between radially inner and outer positions to put a large number of pump ports in the hydraulic pump into communication with the higher and lower pressure oil passages, and an eccentric ring circumscribed about the distributor valves is connected to an input member of the hydraulic pump for movement between a clutch OFF position and a clutch ON position. A clutch spring is connected to the eccentric ring for biasing the eccentric ring toward the clutch OFF position, and a weight is added to the eccentric ring and adapted to exhibit a centrifugal force for moving the eccentric ring toward the clutch ON position against a spring force of the clutch spring.

    • A recording apparatus has a printer mechanism for printing images successively on sheets of copying paper, and an image control circuit for delivering image information controllably to the printer mechanism so as to enable the latter to print the images successively. The image control circuit includes a plurality of page memories each for storing image information per single page, a first changeover switch for writing image information selectively into the page memories, and a second changeover switch for reading image information selectively from the page memories. When a sheet of copying paper is jammed in the printer mechanism, a microcomputer system controls the second changeover switch to select a switching mode to read an item of image information out of one of the page memories which stores the item of information to be printed on the jammed sheet of copying paper, for thereby allowing the image to be printed in a shorter period of time after paper jam clearance.
