Abstract: PURPOSE:To perform loading/unloading by providing an actuator expanded/ compressed by internal pressure between load arms or at an actuator supporting member, deforming the loading arm by controlling the internal pressure, and keeping a disk and a slider at a non-contact state. CONSTITUTION:A ring type actuator 6 is compressed when no disk device is operated and when rotation is started and stopped, and it is deformed so as to increase a distance between the slider 3 and a magnetic disk 1 by pressing the loading arm with a steel sheet 7.

Abstract: PROBLEM TO BE SOLVED: To enable light rays incident on a microlens to impinge efficiently on a photodetecting section aperture without irradiating the outside of the aperture by a method wherein a convex lens with a spherical surface or a nearly spherical surface is made to serve as the microlens. SOLUTION: A microlens 21 is provided over a photodetecting section aperture 18 and formed nearly like a rectangle in a plan view, and a convex lens with a spherical surface, or a nearly spherical surface is made to serve as the micro lens 21. Therefore, the height hV of a micro gap in a vertical direction is set larger than that hH of the micro lens 21 in a horizontal direction. A height difference δh between the heights hV and hH is so set as to make the surface of the micro lens 21 spherical or nearly spherical. By this setup, light rays incident on the micro lens 21 are condensed in a region located at a nearly equal level independent of the lengthwise and widthwise direction of the micro lens 21.  Therefore, a light-condensed region is set at a photodetecting surface, whereby all light rays incident on the micro lens 21 are made to impinge efficiently on a photodedetecting plane without irradiating the outside of the photodetecting section aperture 18.

Abstract: PURPOSE:To minimize the waiting time extending from the turn-on of a recording operation starting command to the start of the recording operation without shortening the service life of a whole recorder by varying the rotational speed of a polygon motor and changing the recording density. CONSTITUTION:An internal timer 20 in a CPU 14 counts the time from a time point when a recording operation is finished and the power source of a main motor 17 is turned off, and a rotation maintaining time determining means 21 in the CPU 14 sets the time to the internal timer 20 so that the lower the rotational speed of a polygon motor 6 by which a rotational speed is controlled so as to be variable, the longer the rotation maintaining time T of the polygon motor 6 after the recording operation is finished. When the counted value of the internal time 20 reaches the rotation maintaining time T, the CPU 14 suspends the output of a polygon motor driving signal to a polygon motor driving circuit 16.

Abstract: PROBLEM TO BE SOLVED: To prevent staple portions from being overlapped at all by shifting a discharge tray each time a stapled transfer paper bundle is thrust when the number of the stapled paper is the prescribed number or below and the number of stapled files is the prescribed number or above. SOLUTION: When a stapled transfer paper bundle is discharged to a discharge tray, the servo motor 706 of a tray shifting means is driven forward, the display tray is shifted to this side, and the discharged transfer paper P is located at the position of a two-dot chain line.

The control means checks the number of stapled paper and the number of stapled files.  When the number of stapled paper is the prescribed number or below and the number of stapled files is the prescribed number or above, the transfer paper bundles are shifted in turn in the width direction and stacked in turn on the discharge tray, staple portions are not overlapped, and the transfer paper bundles can be prevented from becoming excessively bulky.
