Abstract
Abstract A record bearing medium cassette loading device for a recording and/or reproducing apparatus including: a cassette carrying device, which includes an elastic member, and a cassette receiving member arranged to have the cassette held between them and which is arranged to be driven to move in the direction of insertion of the cassette; a position restricting member which restricts the position the elastic member in the cassette carrying device; and a driving mechanism for driving the cassette carrying device in the cassette inserting direction. In loading the cassette, the record bearing medium containing cassette is manually pushed in between the elastic member and the cassette receiving member of the cassette carrying device until the elastic member is restricted by the restricting member. Following that, the driving mechanism performs an inward pulling action on the carrying device. During this pulling action, the cassette holding force of the carrying device is increased by causing the restricting member to act on the elastic member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
In an apparatus using a record bearing medium container, a record bearing medium container loading device comprising: container holding means having an elastic member and a container receiving member, said holding means pinching said container elastically between the elastic member and the container receiving member; control means for controlling the pinch force of said elastic member of said holding means against the container pinched thereby; and driving means for automatically carrying said container holding means into the apparatus in a predetermined inserting direction; wherein the control means increases said pinching force of said elastic member against the container pinched between said elastic member and said container receiving member as said driving means moves the container holding means into the apparatus.
Claim 2
Dependent Claim
120 words
In an apparatus using a record bearing medium container, a record bearing medium container loading device comprising: container holding means having an elastic member and a container receiving member, said holding means pinching said container elastically between the elastic member and the container receiving member; control means for controlling the pinch force of said elastic member of said holding means against the container pinched thereby; and driving means for automatically carrying said container holding means into the apparatus in a predetermined inserting direction; wherein the control means increases said pinching force of said elastic member against the container pinched between said elastic member and said container receiving member as said driving means moves the container holding means into the apparatus.
Claim 3
Dependent Claim
13 words
Apparatus according to claim 1, wherein said recording medium is a magnetic disc.
Claim 4
Dependent Claim
32 words
Apparatus according to claim 1, wherein said control means includes a member for controlling the pressure of said elastic member by pressing said elastic member on a side remote from the container.
Claim 5
Dependent Claim
22 words
Apparatus according to claim 1, wherein said driving means moves the container in two different directions into and out of the apparatus.
Claim 6
Dependent Claim
101 words
A cassette loading apparatus, comprising: (a) an opening for receiving said cassette, (b) pinch means for pinching said cassette inserted through said opening, (c) loading means for automatically loading said cassette from a first position at which the cassette can be inserted into the pinch means through the opening to a predetermined operating position as said cassette is pinched by said pinch means; and (d) control means for controlling the pinch force of said pinch means on said cassette, said control means strengthening the pinch force of said pinch means as said loading means moves the cassette toward the operating position.
Claim 7
Dependent Claim
101 words
A cassette loading apparatus, comprising: (a) an opening for receiving said cassette, (b) pinch means for pinching said cassette inserted through said opening, (c) loading means for automatically loading said cassette from a first position at which the cassette can be inserted into the pinch means through the opening to a predetermined operating position as said cassette is pinched by said pinch means; and (d) control means for controlling the pinch force of said pinch means on said cassette, said control means strengthening the pinch force of said pinch means as said loading means moves the cassette toward the operating position.
Claim 8
Dependent Claim
15 words
An apparatus according to claim 5, wherein said cassette is a magnetic record bearing medium.
Claim 9
Dependent Claim
22 words
An apparatus according to claim 5, wherein said pinch means includes an elastic member which acts on one side of said cassette.
Claim 10
Dependent Claim
33 words
An apparatus according to claim 7, wherein said control means includes a member for controlling the pressure of said elastic member by pressing said elastic member on a side remote from the container.
