Abstract

Abstract A fast-forwarding and rewinding levers operating mechanism in a tape recorder comprisig an FF (fast forward) lever element having formed therein a hook-shaped guide recess, a REW (rewinding) lever element superposed on the FF lever element and which has formed therein a hook-shaped recess so positioned in a direction opposite to said guide recess in the FF lever element as to intersect the latter guide recess, an oscillating member located under said FF and REW lever elements and having an oscillating portion provided at the intersection between said two guide recesses, and a transmission means to oscillate said oscillating member for a rotary medium to engage a reel base, said oscillating portion of the oscillating member being oscillated, by pressing said FF or REW lever element, to put said transmission means into action, thus revolving said reel base for FF or REW operation.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 110 words
A fast-forwarding and rewinding operating mechanism in a tape recorder having a drive mechanism for a tape reel comprising: a fast-forward (FF) lever element having a hook-shaped guide recess; a rewinding (REW) lever element superposed on said FF lever element and having a corresponding hook-shaped guide recess in partial overlapping relation; an oscillating member adjacent said levers pivoted about a fixed pivot and having an oscillating portion extending through both of said guide recesses; and, transmission means connected to said oscillating member and moved with said oscillating member for producing a driving engagement between said drive mechanism and said tape reel in response to movement of one of said levers.
Claim 2
Dependent Claim 110 words
A fast-forwarding and rewinding operating mechanism in a tape recorder having a drive mechanism for a tape reel comprising: a fast-forward (FF) lever element having a hook-shaped guide recess; a rewinding (REW) lever element superposed on said FF lever element and having a corresponding hook-shaped guide recess in partial overlapping relation; an oscillating member adjacent said levers pivoted about a fixed pivot and having an oscillating portion extending through both of said guide recesses; and, transmission means connected to said oscillating member and moved with said oscillating member for producing a driving engagement between said drive mechanism and said tape reel in response to movement of one of said levers.
Claim 3
Dependent Claim 131 words
A fast-forwarding and rewinding operating mechanism in a tape recorder as set forth in claim 1, further including: locking means to lock said FF and REW lever elements in a predetermined position, said locking means comprising: a holding plunger; a locking member; a sub-locking member; a first spring provided between said locking member and sub-locking member and having a biasing force to hold said lever elements in said predetermined position; and, a second spring between said locking member and said sub-locking member to attract said sub-locking member; said FF or REW lever element being returned to the initial position against the holding power of said second spring when said sub-locking member is released by said holding plunger in the conditions where said FF or REW lever element is pressed and locked.
Claim 4
Dependent Claim 54 words
A fast-forwarding and rewinding levers operating mechanism in a tape recorder as set forth in claim 2, wherein said FF or REW lever element has provided thereon a locking tapered portion with which said lever element is locked by means of said locking member, and a releasing taper portion to unlock sid lever element.
