Abstract: PROBLEM TO BE SOLVED: To miniaturize a paper guide mechanism for reversing the paper and to improve the reliability in paper running by making the direction of the paper conveying path unlimited, rotating and moving one of a pair of conveying rollers around the other roller to switch the recording paper conveying direction. SOLUTION: The paper P having an image on a surface thereof, is conveyed to a feeding-out roller 7 side by a driven side conveying roller 3b. When a rear end of the paper P is detected by a paper end detector 2, the rotation of the drive side conveying roller 3a is stopped, and the driven side conveying roller 3b is moved to a position for guiding the rear end of the paper P to the conveying roller 10b. The driving side conveying roller 3a and the feeding- out roller 7 are rotated to convey the paper P to the conveying rollers 10b, 10a, for reversing a front face and a rear face of the paper P. When it is detected that the rear end of the reversed paper P is removed from the drive side conveying roller 3a, by the paper end detector 2, the driven side conveying roller 3b is moved to a position to be guided to the feeding-out roller 7, and an image is formed on the rear face of the paper P.

IPC: F01L13/08
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To provide an automatic decompression device with centrifugal clutch mechanism for cutting off interlock with a crankshaft to open an exhaust valve so as to release compression pressure at the time of starting an engine and interlocking to close the exhaust valve so as to suspend the release of compression pressure after the start of the engine, and make this mechanism removable from the outside part of the engine so as to be fittable with simple structure according to the engine. SOLUTION: A decompression shaft 40 forming an automatic decompression device D is rotatably provided at the axis of a camshaft. At the time of starting an engine, the rotating speed of the camshaft is low, so that a weight of centrifugal clutch mechanism 45 is not opened outward by centrifugal force. The decompression shaft 40 is not therefore rotated, and a decompression pin 42 is protruded by the specified length, so that an exhaust valve is slightly lifted through a locker arm in a compression stroke to release compression pressure. Load at the time of forcibly rotating a crankshaft can thereby be reduced. When the engine is started and the rotating speed of the camshaft becomes high, the weight is opened outward, so that the decompression shaft 40 is rotated, and the decompression pin 42 is not protruded. The exhaust valve is not therefore lifted through the locker arm.
