Dependent claims

A recording and/or reproducing apparatus using a disc shaped flexible recording medium, comprising:

(A) head means for recording signals on said recording medium and/or reproducing recorded signals from the recording medium;
(B) a lid for covering said head means and having a holding member for holding therein said recording medium, said lid being movable supported in said apparatus and thereby closable for causing the recording medium to gain access to said head means and openable for receiving said recording medium;
(C) stabilizing means for stabilizing a portion of said medium, said stabilizing means being supported at a portion of said lid in such a manner as to be movable between an active position at which it can gain access to the recording medium held at said holding member and a non-active position being separated from said recording medium;
and
(D) control means for controlling the movement of said stabilizing menas between said active and non-active positions thereof in correspondence with the opening and closing of said lid, said control means being connected to said said stabilizing means and said main body and operating so as to move the stabilizing means in a first direction with respect to the lid for bringing said stabilizing means into said active position when the lid is closed and operating so as to move the stabilizing means in a second direction with respect to the lid when the lid is opened.

A recording and/or reproducing apparatus using a cassette which houses therein a recording medium, said cassette having opposed surfaces with respective aligned openings, said apparatus comprising:

(A) a main body part having a station for having said cassette loaded thereon;
(B) a lid for covering said station and having a cassette holding member fixed to it for holding said cassette, said lid being movable relative to said main body part between a first position at which the lid uncovers said station of the main body part and a second position at which the lid covers said station;
(C) a recording and/or reproducing head disposed at said station in such a manner than said head gains access to said recording medium housed in said cassette through one of said openings of the cassette when said lid is at said second position;
(D) a stabilizing member which has a predetermined surface for stabilizing a portion of said recording medium which passes said head, said stabilizing member gaining access to said recording medium through one of said openings of said cassette and being attached to said lid for movement relative to said lid so that it can move between an active position to gain access to the recording medium within the cassette held by the holding member and a non-active position separated from said recording medium;
and
(E) control means connected to said stabilizing means and to said main body for stabilizing member relative to said lid and operating so as to move said stabilizing member to said non-active position upon movement of said lid from said second position to said first position and to move said stabilizing member to the active position upon movement of said lid from said first position to said second position.

#1. Field of the Invention

#This invention relates to a recording and/or reproducing apparatus arranged to perform recording or reproduction with a cassette which houses a recording medium such as a magnetic sheet loaded on a cassette receiving part of the apparatus.

#2. Description of the Prior Art

Brief description of the drawings6 figures

#FIG. 1 is an oblique view showing a cassette containing a recording medium.

#FIG. 2 is a sectional view showing a recording and/or reproducing apparatus provided with a conventional recording medium stabilizing arrangement.

#FIG. 3 is a sectional view showing the apparatus of FIG. 2 as in a state of having a cassette receiving part opened for taking out or inserting a cassette.

Detailed description2,531 words

#In the following description, a cassette containing a recording medium, a conventional arrangement for stabilizing a recording medium, first and second embodiment examples of the invention will be described in that order.

#In FIG. 1, the cassette 2 contains therein a flexible magnetic disc or sheet 1. The cassette is provided with a shaft coupling part which is disposed in the center of the magnetic sheet 1 for coupling with a rotation driving shaft of a shaft rotating motor. The cassette 2 which is arranged to contain therein the magnetic sheet 1 is provided with an opening 2a. The opening 2a permits the magnetic sheet 1 and a recording or reproducing head to make a relative movement in contact with each other. Meanwhile, a stabilizing member which will be described later herein is arranged to be inserted through this opening 2a.

#FIGS. 2 and 3 are sectional views showing a portion around a head of a recording and/or reproducing apparatus which is provided with sheet stabilizing arrangement of the prior art. In the state of the apparatus as shown in FIG. 2, the cassette 2 is duly loaded on the apparatus to have the latter in a recording or reproducing condition. In these drawings, a reference numeral 3 denotes a box body of the apparatus; 3a denotes a cassette loading station of the box body 3; 4 denotes an outer lid; 5 denotes an inner lid which is arranged to carry the cassette 2; and 6 denotes an upper stabilizing member attached to the outer lid 4. Both the outer and inner lids 4 and 5 are pivotally carried by a shaft 9 attached to an arm part 10 which is provided on the box body 3 and are thus arranged to be turnable on the shaft 9. The inner lid 5 is provided with extension parts 5a and 5b which are arranged to support the cassette 2 from below. A rising part 5c is formed continuously from the extension part 5b and is arranged to define the fore end position of the cassette 2 when the apparatus is loaded with the cassette. The apparatus includes a lower stabilizing member 7 and a magnetic recording and/or reproducing head 8. They are arranged in the cassette loading station 3a. The head 8 is movable in the radial direction of the sheet 1, that is, in a direction perpendicular to the paper surface of the drawings of FIGS. 2 and 3 as viewed theren by means which is not shown. The upper stabilizing member 6 and the lower stabilizing member 7 are provided with a recess 6a and an opening 7a, which are arranged along the moving path of the head 8.
