Abstract
Abstract An automatic tape loading type magnetic recording and reproducing apparatus comprises means for detecting a feeding of a predetermined length of tape leader from a supply reel and then for stopping the feeding, an automatic take-up reel for automatically engaging and winding the fed-out tape leader, and means for detecting when the tape leader has been engaged and wound by the automatic take-up reel and then for positively driving the tape. The automatic take-up reel has an engaging pawl which engages the tape leader outside of the reel flanges.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
197 words
An automatic tape loading type magnetic recording and reproducing apparatus comprising a supply reel having a roll of tape-like member wound thereon, feeding means for feeding said tape-like member from said supply reel, guiding means for guiding said tape-like member along a predetermined path of travel in the apparatus, means comprising an automatic tape-up reel for automatically engaging and winding said tape-like member in said guiding means, first detecting means for detecting when a predetermined length of said tape-like membeR has been fed to a position where said tape-like member is engaged by said automatic take-up reel, means for substantially stopping said feeding means responsive to the operation of said first detecting means, means for positively rotating said automatic take-up reel responsive to the operation of said detecting means, so as to positively wind the tape-like member on said automatic take-up reel, second detecting means for detecting when said automatic take-up reel is positively winding up said tape-like member, driving means including a capstan and a pinch roller for positively driving the tape-like member, and means for operating said driving means responsive to the operation of said second detecting means, thereby to positively drive said tape-like member.
Claim 2
Dependent Claim
197 words
An automatic tape loading type magnetic recording and reproducing apparatus comprising a supply reel having a roll of tape-like member wound thereon, feeding means for feeding said tape-like member from said supply reel, guiding means for guiding said tape-like member along a predetermined path of travel in the apparatus, means comprising an automatic tape-up reel for automatically engaging and winding said tape-like member in said guiding means, first detecting means for detecting when a predetermined length of said tape-like membeR has been fed to a position where said tape-like member is engaged by said automatic take-up reel, means for substantially stopping said feeding means responsive to the operation of said first detecting means, means for positively rotating said automatic take-up reel responsive to the operation of said detecting means, so as to positively wind the tape-like member on said automatic take-up reel, second detecting means for detecting when said automatic take-up reel is positively winding up said tape-like member, driving means including a capstan and a pinch roller for positively driving the tape-like member, and means for operating said driving means responsive to the operation of said second detecting means, thereby to positively drive said tape-like member.
Claim 3
Dependent Claim
106 words
The apparatus as defined in claim 1 wherein said automatic take-up reel includes an engaging pawl, means in the reel hub for projecting and retracting said pawl, said engaging pawl being normally urged to a pawl portion wherein the forward end of said engaging pawl projects outwardly from the outer periphery of the reel flanges, and said pawl portion has a configuration that catches a leading end portion of said tape-like member when it has been fed out by the predetermined length, said pawl catching said tape responsive to the rotation of said automatic take-up reel when said pawl is positioned outside of said reel flanges.
Claim 4
Dependent Claim
90 words
The apparatus as defined in claim 2 further comprising means including a tape leader guiding member provided along and slightly spaced away from the outer periphery of said automatic take-up reel, said guiding member being positioned to receive the leading end of the predetermined length of tape-like member as it is fed through the predetermined path of travel in the apparatus, and said guiding member retaining said leading end of the tape-like member to a predetermined position, said pawl portion engaging said tape-like member within said tape-like member guiding member.
Claim 5
Dependent Claim
125 words
The apparatus as defined in claim 1 wherein said automatic take-up reel comprises upper and lower reel flanges, a reel hub having an opening, an engaging pawl having at its forward end a pawl portion for engaging the tape-like member, means in said opening of the reel hub for projecting and retracting said pawl, a swingable arm member in said reel hub for swingably supporting the base of said engaging pawl, and a spring member for normally applying a force to urge said engaging pawl to project outwardly from the outer periphery of said reel flanges, said swingable arm member being so constructed that it moves in a pivotal motion to cause said engaging pawl to be projected from and retracted in said reel hub.
Claim 6
Dependent Claim
134 words
The apparatus as defined in claim 1 wherein a predetermined portion of said tape-like member is formed with a slot portion, said first detecting means comprising of a first sensor member for engaging a slot of the slot portion thereby mechanically detecting said predetermined position, means comprising a second sensor member for mechanically detecting a contact thereof with said tape-like member, normally closed first switch means which cooperates with said first sensor member, and normally opened second switch means which cooperates with said second sensor member, said first and second switches being closed for detecting when the predetermined length of tape-like member has been fed out, said detecting means indicating when said first sensor member engages said slot of the tape-like member and said second sensor member simultaneously makes contact with said tape-like member.
Claim 7
Dependent Claim
151 words
The apparatus as defined in claim 1 wherein said tape-like member comprises a tape and a tape leader connected to the leading end of said tape, said tape leader having a wide leader portion of a predetermined width and a narrow leader portion following the wide leader portion, and said second detecting means comprising a guide member having a passage through which said wide leader portion moves and an opening from which said narrow leader portion can be disengaged and which is formed with a recess, a tension arm dimensioned to enter said recess of the guide member, said tension arm being pushed by said narrow leader portion as it is disengaged from said opening, and switch means which cooperates with said arm to open and close a circuit, said tape following said tape leader having a width which is wider than the width of the opening of said guide member.
Claim 8
Dependent Claim
78 words
The apparatus as defined in claim 1 wherein said tape-like member comprises a tape and a tape leader connected to the leading end of said tape, said magnetic recording and reproducing apparatus having a magnetic head assembly means for recording on and reproducing from the tape, said first detecting means being disposed between said supply reel and said magnetic head assembly, and said second detecting means being disposed between said automatic take-up reel and said magnetic head assembly.
Claim 9
Dependent Claim
24 words
The apparatus as defined in claim 7 wherein said tape-like member driving means is disposed between said supply reel and said magnetic head assembly.
Claim 10
Dependent Claim
101 words
An automatic tape feeding system for a magnetic tape recorder comprising means for feeding out a predetermined length of said magnetic tape, said magnetic tape having a leader on opposite ends thereof, each of said leaders having coded slots therein, means for substantially stopping said feeding means after said predetermined length is fed out, means comprising a take-up reel for catching the fed out end of said tape and thereafter winding said tape on said reel, detector means for mechanically detecting said slots to detect said tape position, and means responsive to said detector means for selectively controlling said tape recorder.
Claim 11
Dependent Claim
