摘要： An optical disc apparatus has a bottom cover member provided with an opening. A peripheral part of a unit mechanism deck member serving as a support member in a functional unit mechanism or a motor base holding a spindle motor and fixed to the unit mechanism deck member is projected outside through the opening when the optical disc apparatus is set in a loaded state to space a part of the functional unit mechanism projecting in a direction opposite to a direction in which the peripheral part of the unit mechanism deck member or the motor base is projected outside from a surface of the optical disc.

摘要： An optical disc apparatus includes position restricting component for restricting the position of a unit mechanism portion in a disc plane direction when the unit mechanism portion is in a raised state. The position restricting component includes a first portion that restricts the position of a base of the unit mechanism portion when the base is at a height position for write or read of information to or from an optical disc and a second portion that cancels the position restriction on the base of the unit mechanism portion in the disc plane direction or makes the position restriction easier than in the first portion when the base is at a height position corresponding to a chucked portion of the optical disc onto the turntable. At the height position where the optical disc is chucked the position restricting component makes the turntable displaceable in the disc plane direction so that the axis of the turntable becomes nearly coincident with the center of a center hole formed in the optical disc.

摘要： A magnetic recording and reproducing apparatus has main and sub chassis relatively movable between a first position in which a tape cassette is allowed to be mounted on and demounted from the reel bases and a second position in which magnetic tape extracted from the tape cassette is wound on the head assembly for recording or reproduction of electric signals. The apparatus has a braking mechanism designed for producing a braking effect on at least one of the reel bases when the sub chassis is in the first position. When the sub chassis is in the second position, the braking mechanism is engaged with a brake actuating mechanism on the main chassis so as to selectively brake the reel base in accordance with the state of the brake actuating mechanism operative in response to a manual input.

摘要： A cassette loading device comprises a motor rotatable in a normal direction and in a reverse direction, a driving mechanism for transmitting a power of the motor to a cassette holder and moving the cassette holder, and elastic member mounted on the driving mechanism for generating an elastic force against a depression of a tape cassette when the tape cassette is depressed from an initial position to a cassette-in position. A position detecting device detects that the cassette holder reaches a predetermined position in its moving path and generates a signal, with an initial position detecting device detecting an initial position of the elastic member upon initializing generating a signal. An eject signal generating device generates a signal commanding a cassette unloading, and a micro-processor controls the motor in response to output signals from the position detecting device, the initial position detecting device and the eject signal generating device. The tape cassette is forcibly unloaded irrespective of the elastic force of the elastic member.

摘要： To prevent deformation of a chassis due to an impact force in an optical disc apparatus, there is provided a tray for inserting/ejecting an optical disc into/from an apparatus body, with the chassis connected thereto through vibration proof materials in plural portions in a surface opposite a disc placing surface. The tray has projecting portions projecting in a chassis direction in positions facing the chassis in peripheral portions of the plural connecting portions. The projecting portion is located at a position higher than a tray plane with which the vibration proof material comes into contact, and lower than the surface of a chassis facing the tray. When the vibration proof material is compressed and deformed due to the impact force, the projecting portion comes into contact with the chassis facing surface, to reduce the amount of deformation of the vibration proof material and thereby prevent deformation of the chassis.

摘要： An optical disc apparatus includes, as a raising/lowering mechanism for moving a second base constituting a unit mechanism portion pivotally about a fulcrum so as to raise or lower the second base with respect to a first base as a base of the optical disc apparatus, a cam mechanism which is provided pivotably on the first base side within an orthographic projection area of the optical disc that is in a chucked state and which has a cam surface formed around and in the direction of a pivot shaft. In addition, a cam pin provided on the second base side is brought into engagement with the cam surface. When the optical disc inserted into the optical disc apparatus is chucked onto a turntable so as to be rotatable, the cam mechanism is pivoted about the pivot shaft by a cam drive section.
