Patent ES-8601544-A1 (ES)
Title: Cassette tape recording and/or reproducing apparatus.
IPC: G11B15/295
Filed: 1984-07-30
Abstract: The device includes a member (1) which is rotated when the tape (8) is running and which stops when the tape is fully wound on the reel. A mode-change drive mechanism (37) effects a repeated motion in response to rotation of the tape driving member (9). A cylindrical actuating portion (23) of the member (1) is received in an elongated hole in a mode-change lever which is angularly displaceable about the axis of rotation of the member (1) and is longitudinally displaceable in the direction along the hole. - A spring (30) urges the mode-change lever in one direction along the hole for frictionally engaging converging sides of the hole with the actuating portion. A device (11) establishes another operating mode in response to operation of the mode-change drive mechanism to displace the lever in the opposite direction against the spring only when the member (1) stops rotating.

(31pp Dwg.No.1/8) - EP-133013 B A cassette tape recording and/or reproducing apparatus having a tape driving member (9) which, in a selected operating mode of the apparatus, is rotated for driving the tape (8) in the cassette in the direction for winding the tape (8) onto a take-up reel, and having a device (20) for automatically changing the operating mode of the apparatus when the tape (8) is fully wound on the take-up reel, the device (20) comprising: a rotary member (1) which is rotated when the tape (8) is running and which stops rotating when the tape (8) is fully wound on said take-up reel, said rotary member (1) having a cylindrical actuating portion (23) rotatable coaxially therewith; mode-change drive means (37) effecting a repeated motion in response to rotation of said tape driving member (9) and being operative only when said rotary member (1) stops rotating; an angularly-rotatable mode-change lever (21); and means (11) for establishing another operating mode of the apparatus; characterised by: said mode-change lever (21) having an elongated hole (26) with converging sides in which said cylindrical actuating portion (23) is received so that said mode-change lever (21) is angularly displaceable about the axis of rotation of said rotary member (1) and also longitudinally displaceable in the direction along said elongated hole (26); spring means (30) urging said mode-change lever (21) in one direction along said elongated hole (26) for frictionally engaging said converging sides with said actuating portion (23) and thereby frictionally urging said mode-change lever (21) to turn with said rotary member (1) so long as said rotary member (1) is rotated; and said means (11) for establishing another operating mode of the apparatus operating, in response to said operation of said mode-change drive means (37), to displace said mode-change lever (21) in the opposite direction along said elongated hole (26) against the force of said spring means (30) only when said rotary member (1) stops rotatin USAB- US4604662 A The appts. comprises a pinch roller movable between operative and inoperative positions in respect to a capstan and which is rotated when a tape is running. The roller stops rotating when the tape is fully wound on a take-up reel. The pinch roller has a cylindrical actuating portion rotatable coaxially with it. A mode-change lever has an elongated hole with converging sides in which the cylindrical actuating portion is received so that the mode-change lever is angularly displaceable about the axis of rotation of the pinch roller and also longitudinally displaceable in the direction along the elongated hole. A spring urges the mode-change lever in one direction along the elongated hole for frictionally engaging the converging sides with the actuating portion and thereby frictionally urging the lever to turn with the pinch roller so long as it is rotated. - A device establishes another operating mode of the appts. in  response to displace the mode-change lever in the opposite direction along the elongated hole against the force of the spring. A mode-change drive effects a repeated motion in response to rotation of the capstan and displaces the mode-change lever in the opposite direction only when the pinch roller stops rotating and no longer frictionally urges the mode-change lever to turn angularly about the axis. The mode-change lever is thus moved to an  inoperative position in response to movement of the pinch roller.
