IPC: B65H3/44
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To surely record the images of respective originals on the whole surface of a record medium without making a front page blank even when the single-sided originals are successively fed in turn from the final page and the images thereof are recorded on both surfaces of the recording paper by forming the image on both surfaces for every original grouped according to size. SOLUTION: When the different-size originals are placed on an original platen, a control action is executed by a control means F so that the originals which are fed are successively grouped for every original whose size are identical in turn and the record medium whose size is identical to the original size is fed. Then, the image is formed on both surfaces of the record medium for every grouped original. That means, the originals are grouped according to the original size detected by a means for detecting the number of originals 29 and an original size detection means 30. When the number of grouped originals is the odd number, the image of the first original is formed on one surface of the record medium and the record medium is ejected. Besides, the images of the left originals are formed on both surfaces of the record medium and the record medium is ejected.  When it is the even number, the images of the originals which are fed are formed on both surfaces of the record medium and the record medium is ejected.

Title: Four wheel drive device
Inventor: MATSUMOTO YASUHEI
IPC: B60K17/346
Filed: 1986-07-11
Abstract: PURPOSE:To improve maneuverability and driveability by arranging a multi-plate clutch between a rear wheel side drive shaft and a planetary gear device so that different torque distributions can be selected. CONSTITUTION:A multi-plate clutch 8 is arranged between a rear wheel side drive shaft 4 and a planetary gear device 7 via a gear mechanism. When this clutch 8 becomes a disengaged condition, a drive torque from a transmission is transmitted to both front wheels and rear wheels respectively via the planetary gear device 7. The distribution of the drive torque during driving in this case becomes such that a front torque TF is greater than a rear torque TR according to a gear ratio of a gear 7a to a gear 7d. When the clutch 8 is engaged on the other hand, the drive shaft 4 is directly connected to a ring gear of the planetary gear device 7 and it becomes TF=TR. Accordingly, the torque distribution can be continuously changed by continuously changing hydraulic pressures to the clutch 8. As a result, maneuverability and driveability can be improved.
