Abstract
Abstract A device for controlling the operation of a tape recorder which may be used in miniature tape recorders or in hand-held microphones with remote control of the recorder, includes actuating means for positioning the tape drive into different operating conditions and comprises operating means for selecting the modes of operation "recording" and "playback". The actuating means provides for at least two of the four positions "stop", "slow forward run" for recording and playback, "rewind" and "fast forward run". The operating means comprise, besides a first position "playback" and a second position "recording", a third position "slow forward run+recording" in which the tape drive is in the condition "slow forward run" and the operation "recording" is selected when the actuating device is in the "stop" position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
A control mechanism for controlling the recording and playback functions of a tape recorder comprising: actuating means operably connected to a tape drive means and actuatable to a selected one of a plurality of positions including a "recording" position and a "playback" position in which positions said tape drive means is placed in a "slow forward run" mode; and operable means operably connected to said tape drive means and actuatable, independent of said actuating means, in opposition to a restoring force from a first locked-in "playback" position to a second locked-in "recording" position and to a third non-locked-in "slow forward+recording" position in which said tape drive means is placed in its slow forward run mode independent of the position of the actuating means and the recording mode is selected.
Claim 2
Dependent Claim
129 words
A control mechanism for controlling the recording and playback functions of a tape recorder comprising: actuating means operably connected to a tape drive means and actuatable to a selected one of a plurality of positions including a "recording" position and a "playback" position in which positions said tape drive means is placed in a "slow forward run" mode; and operable means operably connected to said tape drive means and actuatable, independent of said actuating means, in opposition to a restoring force from a first locked-in "playback" position to a second locked-in "recording" position and to a third non-locked-in "slow forward+recording" position in which said tape drive means is placed in its slow forward run mode independent of the position of the actuating means and the recording mode is selected.
Claim 3
Dependent Claim
17 words
The control mechanism claimed in claim 1, wherein said operable means further comprises: a depressible, pressure-responsive key.
Claim 4
Dependent Claim
77 words
The control mechanism claimed in claim 1, wherein said actuating means is actuatable to a selected one of a plurality of positions including said "record" position and said "playback" position and additionally it is operable to a "fast forward run" position or a "rewind" position, said operable means caused to remain in and return to said "playback" position from said "recording" position when said actuatable means is actuated to said "fast forward run" or said "rewind" position.
Claim 5
Dependent Claim
28 words
The control mechanism claimed in claim 1, wherein said actuatable means and said operable means are located adjacent one another and are selectively operable with a single finger.
Claim 6
Dependent Claim
62 words
The control mechanism claimed in claim 2, wherein said pressure-responsive key is slidably mounted relative to a base support for reciprocal movement inwardly and outwardly of said tape recorder, said key being resiliently biased outwardly of said tape recorder by a restoring spring in tension having one end thereof secured to said key and the other end thereof secured to said base.
Claim 7
Dependent Claim
137 words
The control mechanism claimed in claim 5, further comprising: a leaf spring member secured to said key and extending in a direction along the path of movement of said key, said leaf spring mounted for yielding movement in a path transverse to said first mentioned path; said actuatable means includes a lug secured thereto and extending therefrom, said lug positonable in the path of said leaf spring, whereby depression of said key from said "playback" to said "recording" position causes said leaf spring to engage said lug and yield in a first direction transverse to said lug until the end of said leaf spring clears said lug and then yield in a second direction, opposite to said first direction, to prevent the restoring spring force from restoring the key to said "playback" position from said "recording" position.
Claim 8
Dependent Claim
39 words
The control mechanism claimed in claim 6, wherein said key, in its "recording" position, causes recording contacts to effect recording functions and, in its "slow forward run+record" position, additionally closes motor contacts to supply operating voltage to a motor.
Claim 9
Dependent Claim
49 words
The control mechanism claimed in claim 6 said key is released from said leaf spring and restored to said "playback" position by said restoring spring when said actuatable means is actuated to either of said "rewind" or "fast forward run" positions when said key is in said "record" position.
Claim 10
Dependent Claim
37 words
The control mechanism claimed in claim 1, wherein said control functions for said actuatable means and said operable means are effected by a remote control means controllable from a hand held microphone connected to said tape recorder.
