Abstract
A recording and/or reproducing apparatus of the kind using a disc-shaped record bearing medium is provided with a stabilizer plate for stabilizing the rotation of the medium; a center core pressing device for pressing a center core which is secured to the medium against a rotatory drive part; and common support member for supporting both the stabilizer plate and the center core pressing device in common with each other, so that the stabilizer plate and the center core pressing device can be arranged in one unit.
Claims13
A recording and/or reproducing apparatus using a disc shaped flexible record bearing medium having a mounting part, comprising:
- (a) rotation means for rotating said medium, said medium being mountable at the mounting part thereof on said rotation means;
- (b) pressing means for pressing the mounting part of the medium to mount the medium on said rotation means;
- (c) a head for recording and/or reproducing signals on or from the medium;
- (d) stabilizing means for stabilizing at least a portion of the medium when the medium is rotated by said rotation means, said stabilizing means being located on a side of said medium opposite to said head so as to stabilize an opposing state of the head to the medium;
- (e) movable support means common to said pressing means and to said stabilizing means;
- (f) an operation mechanism for operating said pressing means and said stabilizing means, said operation mechanism being operatively connected with said support means, and said operation mechanism acting on said support means according to the mounting of said medium to activate both the pressing means and the stabilizing means;
- and
- (g) means for separating the pressing means from the mounting part of the medium under a state in which the mounting of the medium on said rotation means has been completed.
A recording and/or reproducing apparatus using a disc shaped flexible record bearing medium having a center core and housed in a cassette, said cassette having a pair of windows opposed to each other, said apparatus comprising:
- (a) a loading mechanism for loading the cassette at a predetermined position for signal recording and/or reproduction;
- (b) a spindle driven by a motor and engageable with the center core of the medium;
- (c) a pressing member for pressing the center core of the medium to engage the center core with said spindle;
- (d) a head for recording signals on and/or reproducing signals from the medium, said head being arranged to gain access to the medium through a first one of said windows of the cassette;
- (e) a stabilizing member for stabilizing the medium relative to said head when the medium is rotated by said spindle, said stabilizing member being arranged to gain access to the medium through a second one of said windows of the cassette;
- (f) a movable support member common to said pressing member and said stabilizing member;
- (g) an operation mechanism for operating said pressing member and said stabilizing member, said operation mechanism being operatively connected with said support member, and said operation mechanism acting on the support member according to the loading of the cassette by the loading mechanism to shift both the pressing member and the stabilizing member:
- and
- (h) means for separating the pressing member from the center core of the medium under a state in which the mounting of the medium on said spindle has been completed.
