Inventor: MORISHIGE YUJI
IPC: B65H31/18
Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To position a delivery sheet tray (loading means) exactly by inexpensive and simple control. SOLUTION: The precision of a range sensor varies depending upon the position of a loading surface of a stack tray, that is, a measured distance, and an error between a real distance and the measured distance becomes larger as the distance is long, therefore the stack tray is started to move based on the measured data at a long distance. At the same time, distances are measured successively by the range sensor, and the stack tray is moved until it is detected that the top of a loading sheet of the stack tray is at a prescribed height based on the range data. When the stack tray is moved in such a direction that the precision of the range sensor becomes low, for example, that the distance from the range sensor to the loading surface moves from the nearer side to the farther side, the stack tray is moved based on the measured result before its movement.

IPC: G11B15/18
Filed: 2000-04-13
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording and reproducing device which has a rotary drum head capable of accelerating a tape fast forwarding or rewinding operation further. SOLUTION: At the time of performing a tape fast forwarding or rewinding operation, the rotational speed of the drum motor of a rotary drum type head which is a fixed value, is changed. For example, when a tape running speed at the time of the fast forwarding operation is faster than a speed at a tape winding surface of the rotary drum type head, a resistance to be applied to the tape is reduced by eliminating the speed difference between the tape running speed and the speed at the winding surface while raising the rotational speed to be matched with the tape running speed. Then, the fast forwarding operation is further accelerated. When, the tape approaches its end and the capstan motor included in a capstan is decelerated, the rotational speed of the drum motor is made to be returned to the original fixed value.
