In a cassette recorder having a frame, a tape transport mechanism operable in fast forward and fast rewind modes in response to a control device therefore, and a cassette handling mechanism mounted in said frame, and a motor driving said tape transport mechanism: a slide member reciprocable on a bridge of said frame between an internal, retracted position and an external, extracted position, said slide having a slot therein and having a front end and a rear end; a spring biasing said slide toward its external position; an arm pivoted in said frame and carrying a recording head, an erase head and a pressure roller of a capstan, said arm also carrying a pivot engaging said slot in said slide to shift said heads and said pressure roller into inoperative positions when the slide is pushed inward into its retracted position and to shift said heads and pressure roller into operative positions when said slide is moved to its extracted position; a handle linked to the front end of said slide and engaging said arm and the control device for selecting the fast forward and rewind modes of said tape transport mechanism, said recorder further including a fork-shaped element hinged to said frame, one side of said fork-shaped element having a cam surface coacting with a pin rigid with said slide to be rotated when said slide is moved into its extracted position; a gripper support lever pivoted on said frame for rotation and having a free end; a cassette gripper fulcrumed to the free end of said gripper support lever; an anchor fulcrumed to said bridge and resiliently biased towards and engaging said slide when the latter reaches its internal, retracted position and releasing said slide when said gripper is pressed against it; a bistable spring interconnecting said free end of said gripper support lever with a cam fulcrumed on said bridge; crosspieces on said frame resiliently biased for cassette lifting movement; said gripper being arranged such that the insertion of a cassette into said cassette recorder causes the front rim of the cassette to strike said gripper thereby rotating said gripper support lever until said bistable spring thrusts said gripper support lever to a position in which said gripper abuts against said anchor.

Claim 5

In a cassette recorder having a frame, a tape transport mechanism operable in fast forward and fast rewind modes in response to a control device therefor, and a cassette handling mechanism mounted in said frame, and a motor driving said tape transport mechanism: a slide member reciprocable on a bridge of said frame between an internal, retracted position and an external, extracted position, said slide having a slot therein and having a front end and a rear end; a spring biasing said slide toward its external position; an arm pivoted in said frame and carrying a recording head, an erase head and a pressure roller of a capstan, said arm also carrying a pivot engaging said slot in said slide to shift said heads and said pressure roller into inoperative positions when the slide is pushed inward into its retracted position and to shift said heads and pressure roller into operative positions when said slide is moved to its extracted position; a handle linked to the front end of said slide and engaging said arm and the control device for selecting the fast forward and rewind modes of said tape transport mechanism, said recorder further including a twin lever hinged to frame, said twin lever having an upper arm forming a two-armed lever and a lower arm forming an elbow lever, one end of said double armed lever being linked through a pin to said handle which is in turn linked to said slide and said one end of said double armed lever also being linked through a tongue depending from said end, to an ear of the arm which carries said heads and said pressure roller; the other end of said two-armed lever coacting with the pivot which engages the slot in said slide; and a pivoted flip-over arm forming a part of said control device for said tape transport mechanism, said arm being swingable between first and second positions representing the fast forward and fast rewind modes of said mechanism, one end of said elbow being linked to said flip-over arm.

Claim 6

In a cassette recorder having a frame, a tape transport mechanism operable in fast forward and fast rewind modes in response to a control device therefor, and a cassette handling mechanism mounted in said frame, and a motor driving said tape transport mechanism: a slide member reciprocable on a bridge of said frame between an internal, retracted position and an external, extracted position, said slide having a slot therein and having a front end and a rear end; a spring biasing said slide toward its external position; an arm pivoted in said frame and carrying a recording head, an erase head and a pressure roller of a capstan, said arm also carrying a pivot engaging said slot in said slide to shift said heads and said pressure roller into inoperative positions when the slide is pushed inward into its retracted position and to shift said heads and pressure roller into operative positions when said slide is moved to its extracted position; a handle linked to the front end of said slide and engaging said arm and the control device for selecting the fast forward and rewind modes of said tape transport mechanism, said recorder further including a twin lever hinged to frame, said twin lever having an upper arm forming a two-armed lever and a lower arm forming an elbow lever, one end of said double armed lever being linked through a pin to said handle which is in turn linked to said slide and said one end of said double armed lever also being linked through a tongue depending from said end, to an ear of the arm which carries said heads and said pressure roller; the other end of said two-armed lever coacting with the pivot which engages the slot in said slide; and a pivoted flip-over arm forming a part of said control device for said tape transport mechanism, said arm being swingable between first and second positions representing the fast forward and fast rewind modes of said mechanism, one end of said elbow being linked to said flip-over arm.

Claim 7

A cassette recorder according to claim 3, wherein the handle has an extension and a slot penetrating into said handle to receive the front end of said slide, said extension having a groove extending longitudinally therealong to receive the pin which links said double armed lever to said handle, there being two pivots inserted in two vertical bores traversing said handle on opposite sides of said extension, one of said pivots abutting against an edge of the front end of said slide to act as a fulcrum when said handle is rotated in one direction, to swing said flip-over arm toward its rewind position, the other pivot abutting against an opposite edge of the front end of said slide when the handle is rotated in an opposite direction, to swing said flip-over arm toward its fast forward position, both rotations causing the arm which carries said heads and said pressure roller to swing away from the cassette.

Claim 8

A cassette recorder according to claim 4, wherein said cassette gripper includes an angle lever having a first arm fulcrumed to said gripper support lever and having a second arm forming a hook to engage one lateral border of a standard cassette when the cassette, during its insertion into said cassette recorder, strikes said first arm of said angle lever.
