Resilient tape guide assembly for tape recording and/or reproducing apparatus

Claim 2

In a tape recording and/or reproducing apparatus having a tape guide drum with a circumferential slot, and at least one rotary transducer projecting through said slot for recording and/or reproducing signals on a tape running against the periphery of said drum in a path which extends about at least a portion of said periphery; a guide assembly for the tape on said drum comprising rigid guide means extending along said portion of the drum periphery and engageable by one longitudinal edge of the tape in said path for establishing the direction and location of said path, and a plurality of resilient elongated guide elements spaced apart along said portion of the drum periphery and having respective contact end portions individually acting yieldably against the other longitudinal edge of the tape at apaced apart locations along the latter in said path for holding the tape in contact with said rigid guide means while accommodating variations and changes in the width of said tape, each of said resilient guide elements including an anchoring end portion fixed relative to said drum, and an intermediate portion extending along the periphery of said drum from said anchoring end portion to said contact end portion and being inclined toward said path with said contact end portion being resiliently swingable about an axis defined by said anchoring end portion.

Claim 3

A tape recording and/or reproducing apparatus according to claim 1; in which said intermediate portion of each of said resilient guide elements extends generally in the direction of running of the tape in said path.

Claim 4

In a tape recording and/or reproducing apparatus having a tape guide drum with a circumferential slot, and at least one rotary transducer projecting through said slot for recording and/or reproducing signals on a tape running against the periphery of said drum in a path which extends about at least a portion of said periphery; a guide assembly for the tape on said drum comprising rigid guide means extending along said portion of the drum periphery and engageable by one longitudinal edge of the tape in said path for establishing the direction and location of said path, and a plurality of resilient guide elements spaced apart along said portion of the drum periphery and individually acting yieldably against the other longitudinal edge of the tape in said path for holding the tape in contact with said rigid guide means while accommodating variations and changes in the width of said tape, each of said resilient guide elements including an anchoring end portion fixed relative to said drum, a contact end portion engageable against said other longitudinal edge of the tape and an intermediate portion extending along the periphery of said drum from said anchoring end portion to said contact end portion and being inclined toward said path with said contact end portion being resiliently swingable about an axis defined by said anchoring end portion, and in which said drum has first and second radial bores for each of said resilient guide elements, said first and second radial bores open at said periphery of the drum at locations spaced apart along said periphery, and each of said resilient guide elements is generally U-shaped and has its anchoring end portion and contact end portion respectively fixed and movable within the associated first and second bores.

Claim 5

In a tape recording and/or reproducing apparatus having a tape guide drum with a circumferential slot, and at least one rotary transducer projecting through said slot for recording and/or reproducing signals on a tape running against the periphery of said drum in a path which extends about at least a portion of said periphery; a guide assembly for the tape on said drum comprising rigid guide means extending along said portion of the drum periphery and engageable by one longitudinal edge of the tape in said path for establishing the direction and location of said path, and a plurality of resilient guide elements spaced apart along said portion of the drum periphery and individually acting yieldably against the other longitudinal edge of the tape in said path for holding the tape in contact with said rigid guide means while accommodating variations and changes in the width of said tape, each of said resilient guide elements including an anchoring end portion fixed relative to said drum, a contact end portion engageable against said other longitudinal edge of the tape and an intermediate portion extending along the periphery of said drum from said anchoring end portion to said contact end portion and being inclined toward said path with said contact end portion being resiliently swingable about an axis defined by said anchoring end portion, and in which said drum has first and second radial bores for each of said resilient guide elements, said first and second radial bores open at said periphery of the drum at locations spaced apart along said periphery, and each of said resilient guide elements is generally U-shaped and has its anchoring end portion and contact end portion respectively fixed and movable within the associated first and second bores.

Claim 6

A tape recording and/or reproducing apparatus according to claim 3; in which said anchoring end portion of each said resilient guide element is adjustably turnable in the respective first bore, and means are provided to lock said anchoring end portion against turning in said respective first bore.

Claim 7

A tape recording and/or reproducing apparatus according to claim 3; in which each said generally U-shaped resilient guide element is formed of a length of spring wire.

Claim 8

A tape recording and/or reproducing apparatus according to claim 5; in which said anchoring end portion of each said resilient guide element includes a coil section.
