Abstract:
An optical disc drive, comprising: a housing; a tray for transferring an optical disc, having a disc mounting portion for mounting the optical disc thereon, and being movable into an inside and a front of the housing; a motor for rotationally driving said optical disc; an optical pickup, having one or more of laser diode(s) for generating a laser beam for conducting recording/reproducing of information onto/from the optical disc, and for irradiating the laser beam upon the optical disc; and a first penetrating hole, for letting the rotation device and the laser beam passing therethrough, being provided within the disc mounting portion and also in rear of said disc mounting portion, on the tray, wherein a second penetrating hole is further provided in rear of the disc mounting portion, in an upstream side of rotating direction of the optical disc than the first penetrating portion, and the second penetrating portion is larger in area than a total of area(s) obtained by projecting the laser diode(s) onto the optical disc, or a protuberance is further provided in an upper side of the tray, within an upstream side of rotation of the optical disc than the second penetrating portion.
Abstract:
An image forming apparatus according to the present invention allows a portable type external storage medium that can store image data to be attached to or detached from the apparatus main body. The image forming apparatus has a data protection means. In a normal operation, the data protection means allows image data stored in an internal storage device (HDD, etc.) or image data stored in the external storage medium to be processed in the image processor and outputs the processed image data to a printer section for printing. In the case where confidential image data is processed, the data protection means inhibits the image data from being saved in the internal storage device and allows only the image data from the external storage medium to be processed in the image processor after attachment of the external storage medium to the apparatus main body has been detected.
Abstract:
Printing is started while the trays 11 and 12 of the paper ejection unit 10 are held at the current positions if the state key 4c on the control panel 4 is turned on when printing under the copy function.
Abstract:
A tape running guide and tape loading mechanism for a magnetic tape recording and reproducing apparatus including a tape guiding system having, at a tape supply side, at least a first movable slanted pin and a first movable tape height regulating guide roller for deriving a tape from an open space of a magnetic tape cassette and winding the tape on a cylindrical drum, a second slanted pin and a second tape height regulating guide roller and third movable guide pin for winding the tape on the second slanted pin. At a tape returning side, a fourth movable slanted pin and a fourth movable tape height regulating guide roller for deriving the magnetic tape from the open space of the tape cassette and winding the magnetic tape on the cylindrical drum a fifth movable slanted pin and a pinch roller which are to be derived from the open space of the tape cassette and a capstan in arranged outside the open space. The movable tape guide members are movable in the common area and a time-shared manner to thereby make the loading mechanism compact.
Abstract:
A plurality of tape guides are moved to wind a magnetic tape on a rotatable cylinder when the magnetic tape is to be loaded. An auxiliary guide mounted on a chassis of a magnetic recording and/or reproducing apparatus in position is made to touch the magnetic tape during a period for which the magnetic tape is being loaded, but it does not touch the magnetic tape when the magnetic tape has been loaded. The auxiliary guide can be protruded toward the magnetic tape from between the tape guides moving to touch the magnetic tape during the period for which the magnetic tape is being loaded so that the magnetic tape can be kept to a predetermined span.
Abstract:
A rotary magnetic head cylinder device for use in a helical-scanning system video tape recorder has a projection provided on a tape running race of a stationary lower cylinder near a location at which a magnetic tape leaves from the lower cylinder. The projection is preferably integral with the tape running race and has a small area which is defined by a shoulder circumferentially extending identically with a tape guide shoulder contouring the lower edge of the tape running race and which spreads perpendicularly to the tape running race, and an upper surface coplanar with the top face of the lower cylinder, and a height defined by a protruded length radially outwardly toward the outer circumferential surface of the lower cylinder. The projection serves to reduce vibrations of the magnetic tape generated when the video head carried by the rotary upper cylinder leaves from the magnetic tape.
