Abstract
Abstract A signal recording/reproducing apparatus for use with a tape cassette comprises a cylinder assembly having an outer peripheral surface. The cylinder assembly has mounted thereon heads for recording and reproducing a signal on and from a magnetic tape in the tape cassette, respectively, and a lead formed on the outer peripheral surface of the cylinder assembly so as to helically extend, to define a running path of the magnetic tape on the outer peripheral surface of the cylinder assembly. A pair guides guide the tape so that the tape is helically wound over a predetermined angular extent along the lead upon the recording/reproducing of the signal. The pair of tape guides are located and oriented in their predetermined positions such that the tape guides impart a force to the tape to press the tape onto the lead during recording and reproduction thereby to permit the tape to move along the lead.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
224 words
A signal recording/reproducing apparatus for use with a tape cassette, comprising: a cylinder assembly having an outer peripheral surface, said cylinder assembly having mounted thereon heads for recording and reproducing a signal on and from a magnetic tape within the tape cassette, respectively, and a lead formed on the outer peripheral surface of said cylinder assembly so as to helically extend, to define a running path of the tape on the outer peripheral surface of said cylinder assembly; and a pair of tape guide means for guiding said tape such that said tape is helically wound around said outer peripheral surface of said cylinder assembly over a predetermined angular extent along said lead upon the recording and reproducing of the signal, one of said tape guide means being, upon the recording/ reproducing of the signal disposed at an approaching side of said cylinder assembly in which said tape approaches said cylinder assembly while the other tape guide means is disposed at a leaving side in which the tape runs away from the cylinder assembly; and upon the recording/reproducing of the signal, said pair of tape guide means being located and oriented in their predetermined positions with respect to said cylinder assembly to impart a force to said tape to press the same against said lead to enable said tape to run along said lead.
Claim 2
Dependent Claim
224 words
A signal recording/reproducing apparatus for use with a tape cassette, comprising: a cylinder assembly having an outer peripheral surface, said cylinder assembly having mounted thereon heads for recording and reproducing a signal on and from a magnetic tape within the tape cassette, respectively, and a lead formed on the outer peripheral surface of said cylinder assembly so as to helically extend, to define a running path of the tape on the outer peripheral surface of said cylinder assembly; and a pair of tape guide means for guiding said tape such that said tape is helically wound around said outer peripheral surface of said cylinder assembly over a predetermined angular extent along said lead upon the recording and reproducing of the signal, one of said tape guide means being, upon the recording/ reproducing of the signal disposed at an approaching side of said cylinder assembly in which said tape approaches said cylinder assembly while the other tape guide means is disposed at a leaving side in which the tape runs away from the cylinder assembly; and upon the recording/reproducing of the signal, said pair of tape guide means being located and oriented in their predetermined positions with respect to said cylinder assembly to impart a force to said tape to press the same against said lead to enable said tape to run along said lead.
Claim 3
Dependent Claim
129 words
A signal recording/reproducing apparatus according to Claim 1, wherein upon the recording/ reproducing of the signal, said pair of tape guide means are located and oriented in their predetermined positions such that a portion of the tape extending between said one tape guide means and a generating line on said cylinder assembly at which the contact of the tape with said cylinder assembly is initiated at said approaching side forms a first predetermined angle of incidence together with said lead and, a portion of said tape extending between said other tape guide means and a generating line on said cylinder assembly at which the contact of said tape with said cylinder assembly is terminated forms a second predetermined angle of incidence together with said lead at said leaving side.
Claim 4
Dependent Claim
23 words
A signal recording/reproducing apparatus according to Claim 2, wherein said pair of tape guide means are beforehand set at said respective predetermined positions.
Claim 5
Dependent Claim
124 words
A signal recording/reproducing apparatus according to Claim 3, wherein said pair of tape guide means are movable between an unloading position apart from said cylinder assembly and a loading position adjacent to said cylinder assembly, said pair of tape guide means withdrawing said tape out of said tape cassette when they are moved from said unloading position to said loading position, said pair of tape guide means being located at said loading position during recording and reproducing of the signal, each of said pair of tape guide means including a setting guide element positioned adjacent to said cylinder assembly in said loading position, the setting guide elements of said pair of tape guide means determining said first and second predetermined angles of incidence, respectively.
Claim 6
Dependent Claim
36 words
A signal recording/reproducing apparatus according to Claim 4, wherein each of said pair of tape guide means includes a non-rotatable guide element and a rotatable guide element, said non-rotatable guide element constituting said setting guide element.
Claim 7
Dependent Claim
24 words
A signal recording/reproducing apparatus according to Claim 5, wherein said first and second predetermined angles of incidence range between about 0.5° and about 2.0°.
Claim 8
Dependent Claim
57 words
A signal recording/reproducing apparatus according to Claim 6, wherein said one and the other of said pair of tape guide means in said loading position have a difference in elevation therebetween with respect to a reference plane which is perpendicular to the axes of rotation of a supply reel and a take-up reel in said tape cassette.
Claim 9
Dependent Claim
52 words
A signal recording/reproducing apparatus according to Claim 7, wherein said cylinder assembly includes a fixed cylinder and a rotatable cylinder which is rotatable relative to said fixed cylinder, said lead being formed on the outer peripheral surface of said fixed cylinder, said heads being mounted on said rotatable cylinder for rotation therewith.
Claim 10
Dependent Claim
40 words
A signal recording/reproducing apparatus according to Claim 8, wherein said non-rotatable guide element and said rotatable guide element in each of said pair of tape guide means are movable between said loading position and said unloading position as a unit.
