Abstract
Abstract A tape-autoloading type recording and/or reproducing apparatus comprises a tape out from the interior of a cassette to the outside thereof. The tape thus drawn out is pulled along a predetermined tape path thereby to wrap the same around the circumference of a guide drum. Motive power is transmitted from a single motive power source, first to the tape drawing out means and then to the tape pulling around means. The motive power transmitting means detects the arrival of the drawing out means approximately at a predetermined position and changes over to the pulling around means thereby stopping the motive power transmission to the drawing out means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
282 words
An automatic tape loading type recording and/or reproducing apparatus comprising: a guide drum having a cylindrical surface with at least one rotating head; a tape cassette having built in tape reels for holding a tape and having a housing provided with an opening extending from a front surface to a part of a bottom surface thereof; tape drawing out means comprising at least one movable lever means having a tape drawing out and guiding member which is inserted into said cassette to make contact with the inner side of said tape; moving means for moving said tape drawing out means to a predetermined position thereby to cause said tape drawing out and guiding member to draw the tape out of the cassette via said opening in said cassette housing; tape pulling around means for intercepting the tape thus drawn out and for pulling the tape around in a manner to cause the tape to wrap around a predetermined arcuate portion of the cylindrical surface of said guide drum; a single driving power source; first driving power transmitting means operating at the start of tape loading to transmit the driving power of said single driving power source to said moving means; means for detecting the completion of the movement of said tape drawing out means to said predetermined position; second driving power transmitting means operating in response to the operation of said detecting means to start the transmission of the driving power of said single driving power source to said tape pulling around means; and means operating in response to the start of operation of said tape pulling around means to cause said first driving power transmitting means to cease transmitting driving power.
Claim 2
Dependent Claim
282 words
An automatic tape loading type recording and/or reproducing apparatus comprising: a guide drum having a cylindrical surface with at least one rotating head; a tape cassette having built in tape reels for holding a tape and having a housing provided with an opening extending from a front surface to a part of a bottom surface thereof; tape drawing out means comprising at least one movable lever means having a tape drawing out and guiding member which is inserted into said cassette to make contact with the inner side of said tape; moving means for moving said tape drawing out means to a predetermined position thereby to cause said tape drawing out and guiding member to draw the tape out of the cassette via said opening in said cassette housing; tape pulling around means for intercepting the tape thus drawn out and for pulling the tape around in a manner to cause the tape to wrap around a predetermined arcuate portion of the cylindrical surface of said guide drum; a single driving power source; first driving power transmitting means operating at the start of tape loading to transmit the driving power of said single driving power source to said moving means; means for detecting the completion of the movement of said tape drawing out means to said predetermined position; second driving power transmitting means operating in response to the operation of said detecting means to start the transmission of the driving power of said single driving power source to said tape pulling around means; and means operating in response to the start of operation of said tape pulling around means to cause said first driving power transmitting means to cease transmitting driving power.
Claim 3
Dependent Claim
102 words
The apparatus according to claim 1 in which the tape pulling around means comprises a revolving ring-shaped member encompassing the guide drum and revolvably supported with an inclination relative to the rotating surface of said at least one rotating head and a tape guiding member secured to said revolving ring-shaped member and adapted to intercept the drawn out tape and pull around the same in concert with the revolution of the ring-shaped member, and said second transmission means includes roller means for making contact against the internal circumferential surface of the revolving ring-shaped member and to drive the same in revolving movement.
Claim 4
Dependent Claim
89 words
The apparatus according to claim 1 in which said first transmission means includes a driving roller which is driven by the single driving power source and a driving belt pressed against said driving roller thereby to receive rotational power therefrom and operating to transmit said power to the moving means, and said means for causing the first transmission means to cease transmitting driving power includes means operating in response to the start of operation of the tape pulling around means to separate said driving belt from said driving roller.
Claim 5
Dependent Claim
149 words
The apparatus according to claim 1 which further comprises braking means for applying braking torque to the rotation of a tape reel for supplying the tape from the interior of said cassette housing, control means for detecting the tension of the tape thus supplied and controlling accordingly said braking torque of the braking means, and an engagement member for making contact against and engaging said control means while the tape drawing out means is operating and separating from and releasing the control means when the tape pulling around means starts to operate, the control means being engaged by said engaging member during operation of the tape drawing out means thereby to cause said braking means to remove said braking torque and being released By and separated from the engagement member during operation of the second tape guiding means thereby to cause the braking means to carry out braking operation.
Claim 6
Dependent Claim
63 words
The apparatus according to claim 1 which further comprises means for locking the tape drawing out means when it has moved to said predetermined position, and said tape drawing out and guiding member operates as a tape guiding member also with respect to the path of travel of the tape after automatic tape loading by the operation of the tape pulling around means.
