Title: Automatic focusing device
Inventor: ISHIBASHI KENJI
IPC: G02B7/28
Filed: 1986-10-20
Abstract: PURPOSE:To prevent a focus detection cycle from becoming longer than required by setting the limit of the integration time of a photodetecting element according to the variation speed of defocusing accompanying the driving of a photographic lens in low contrast searching operation. CONSTITUTION:An automatic focus adjusting device which detects focusing and makes an automatic focus adjustment according to the output of the photodetecting element decides the variation speed of defocusing accompanying the lens driving at the time of the low contrast scanning, and sets an integral time limit shorter than a normal integration time if the variation speed is large to prevent the focusing position of an object from being overlooked. When the defocusing speed is small, on the other hand, there is not any possibility of the focusing position of the object being overlooked, so the low contrast scanning is stopped when the focus detection becomes possible to decide focusing normally and control the lens driving.

Abstract: PROBLEM TO BE SOLVED: To eliminate the adjustment of the energizing forze of energizing means for paper sheet separating claws and to surely supply a different kind of paper sheet by moving freely the paper sheet separating claws between a contact position where they are put into contact with both front corners of the paper sheet facing a paper feed roller in the direction of carrying and a contact releasing position where they are not put into contact with them. SOLUTION: If a paper sheet has a thickness of not more than a prescribed value or an elastic force of not more than a specified value, paper sheet separating claws 54 are put into contact with both front corners of stacked paper sheets. The uppermost paper sheet to which a carrying force is applied is prevented from being moved by the contact with the paper sheet separating claws 54 and then is carried with the paper sheet between both front corners deflected and slipped from the paper sheet separating claws 54.  When the paper sheet has a thickness of not less than a prescribed value or an elastic force of not less than a prescribed value, paper sheet separating claws 54 are disposed at a contact releasing position where they are separated from the stacked paper sheets 70 and are not put into contact with them and hence both front corners of the uppermost paper sheet 70a are allowed to move in the direction away from press plates 46a, 46b, thereby getting over a friction separating slanting part 26 and being carried.

Abstract: PURPOSE:To stabilize the recording characteristics of a delivered liquid drop at all times and maintain a recorded image at high quality level over a long period of time by a method wherein retained ink is put into a state that the molecular bonding state of a liquid medium including in ink is microscopically uniformized and scattered and, at the same time, a means for maintaining ink characteristics is provided at an ink retaining part. CONSTITUTION:In the ink used here, by giving energy such as electrical-, magnetic-, supersonic-energy or the like to water, for example, its molecular bonding state is microscopically uniformized and scattered. Further, in a recording head, supersonic wave generating device is provided at some part in an ink retaining part. At recording, ink is charged from a common ink chamber 7 into an ink flow path 4. Under the state just mentioned above, by applying printing recording electric signal to a heater 5, the heater 5 generates heat in order to give heat energy to the ink in the flow path 4 near the heater 5. When heat energy is given from the heater 5 to the ink, the generation of a bubble, which is accompanied by instantaneous volumetric increase of the ink, occurs in the flow path 4. As a result, the ink on the delivery port 3 side from the heater 5 is delivered through a delivery port 3, resulting in producing the flying liquid drop of the ink.
