Filed: 1990-11-16
Abstract: PURPOSE:To make recording characteristics of each air outlet port uniform by disposing an annular air chamber provided in the periphery of an ink chamber and also providing a shut-off wall for shutting off a path between the air chamber and an air flow passage. CONSTITUTION:During an ink jet recording operation, air is fed from an air supply source 116 into an annular air chamber 106, and ink is supplied from an ink supply source 117 into an ink chamber 108. In this instance, air flowing into the annular air chamber 106 through an air feed tube 114 immediately enters an air flow passage 107 from its circumference. In this case, since spaces among the upper and lower ends of the air chamber 106 and the air flow passage 107 are shut off by shut-off walls 119, the air bypasses the shut-off walls 119 and forms an air stream A' flowing into the air flow passage 107 only from both right and left sides normal to the direction in which ink discharge ports 109a, 109b,... are vertically arrayed. In this case, since the annular air chamber 105 is formed into a symmetrical shape, the inflow amount and flow rate of the air from each of both the right and left sides become equal to each other. Accordingly, air streams flowing out of a plurality of air outlet ports 110a, 110b,... arranged in positions opposed to a plurality of the ink discharge ports 109a, 109b,... arranged on the center line of the air flow passage 107 are all made uniform at their flow rates and in their outflow directions.

During the time for generating perfume, perfume is generated intermittently, and the consumption of the perfume component is reduced, and the deterioration of the perfume sensitivity fat a person is prevented. Further, the perfume generation interval and the perfume generation quantity are properly applied with fluctuation, and the refresh effect in the human engineering aspect is improved. The perfume generation quantity is controlled during the time when the opening/ closing valve is in opened state.

Filed: 1993-12-13
Abstract: PURPOSE:To prevent a jammed original due to meandering and a damaged original by detecting a meandering quantity of a fed original with a detection sphere and driving a correction sphere so as to make the meandering quantity zero. CONSTITUTION:When a feed roller 2 is driven to feed an original, the original is driven in a drive direction shown A in the figure while being pressed by the feed roller 2. A detection sphere 3 is in press contact with the original closely apart from the ypperstream side of a midpoint of the feed roller 2 and a correction sphere 8 is in press contact with the original closely apart from the downstream side of the midpoint of the feed roller 2. The detection sphere 3 provides an output of analog values of coordinates X, Y of a displacement of a spherical rotor rolling on a plane. In this case, when meandering takes place in the original, the rotor is rotated relatively and then a value corresponding to the meandering quantity is outputted and an encoder 4 encodes the output and the result is stored in a memory 5. A feedback control circuit 6 gives a correction signal 601 to a drive mechanism 7 so as to cancel out the meandering quantity 501 read from the memory 5.
