Abstract
Abstract A single operating member for controlling tape recorders of the type having slow forward movement of the tape for reproducing or recording, fast forward movement of the type, and fast rewinding of the tape. The operating member comprises two portions pivotally connected to each other. One portion supports the magnetic head. In its rest position the magnetic head is spaced from the tape which may have a plurality of recording tracks. By pushing in the operating member the magnetic head is brought into engagement with the tape and a switch operatively connected to the operating member effects the movement of the tape at a slow forward speed. Fast forward and rewinding movement of the tape are effected by rotating the portion of the operating member remote from the magnetic head to one side and the other of a central rest position. In the fast forward or rewinding positions, the magnetic head can not be brought into contact with the tape. A vertical movement of the operating member enables the magnetic head to be brought into operative engagement with the various tracks of the tape. The operating member is locked in the recording or reproducing position and is released by the energization of an electromagnet by means of conductive segments on the tape.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
283 words
In a tape recorder of the type having drive and guide means for effecting the movement of a tape along a predetermined path, and a head engageable with a guided tape, first control means for slow forward movement of the type, second control means for fast forward movement of the tape, third control means for rewinding the tape, a single operating member for selectively individually actuating each of said control means,said operating member having a first control position for slow forward movement of the tape, a second control position for the fast forward movement of the tape, a third control position for rewinding the tape and a fourth control position in which the tape is at rest, said operating member including means at one end thereof for mounting thereon for movement therewith said magnetic head, a guide member adjacent the other end of said operating member for defining paths of movement of said operating member other end, mounting means mounting said operating member one end for controlled axial movement to engage said head with a tape during movement of said operating member to said first control position and the actuation of said first control means, and stop means cooperable with said guide member for preventing axial movement of said operating member when said operating member is in any one of said second, third and fourth control positions and during movement therebetween, said stop means being operable for preventing engagement of said head with a tape in all positions of said operating member with the exception of said first control position, and said mounting means including pivot means pivotally mounting said operating member for disengagement from said stop means in said first control position.
Claim 2
Dependent Claim
283 words
In a tape recorder of the type having drive and guide means for effecting the movement of a tape along a predetermined path, and a head engageable with a guided tape, first control means for slow forward movement of the type, second control means for fast forward movement of the tape, third control means for rewinding the tape, a single operating member for selectively individually actuating each of said control means,said operating member having a first control position for slow forward movement of the tape, a second control position for the fast forward movement of the tape, a third control position for rewinding the tape and a fourth control position in which the tape is at rest, said operating member including means at one end thereof for mounting thereon for movement therewith said magnetic head, a guide member adjacent the other end of said operating member for defining paths of movement of said operating member other end, mounting means mounting said operating member one end for controlled axial movement to engage said head with a tape during movement of said operating member to said first control position and the actuation of said first control means, and stop means cooperable with said guide member for preventing axial movement of said operating member when said operating member is in any one of said second, third and fourth control positions and during movement therebetween, said stop means being operable for preventing engagement of said head with a tape in all positions of said operating member with the exception of said first control position, and said mounting means including pivot means pivotally mounting said operating member for disengagement from said stop means in said first control position.
Claim 3
Dependent Claim
65 words
A device according to claim 1, wherein the device is adapted to receive a tape having a plurality of tracks and said mounting means for said operating member enables the vertical displacement of the operating member for selectively positioning the head relative to each one of said tracks, and said guide member further comprising means for maintaining the operating member in each such selected position.
Claim 4
Dependent Claim
69 words
A device according to claim 2 wherein said operating member is formed of first and second portions connected together by a transverse pivot disposed generally parallel to that portion of said tape path aligned with said head, said first portion having thereon said means for mounting said head and being engaged by said mounting means, and said second portion being engaged by said stop means and said guide member.
Claim 5
Dependent Claim
