Abstract
Abstract In a driving mechanism for a tape recorder, rewinding operation of the tape at high speed may be effected by moving a fast-feed operation member to activate both a main switch and a high-speed switch to effect high speed driving of a tape rewinding reel. A first rotary lever is adapted to be actuated either by the fast-feed operating member to actuate the main switch or by a changeover operation member which sets the driving mechanism to the rewinding position. A tape driving member for transmitting tape driving force to either a tape winding reel or the tape rewinding reel is pivotally actuated by a second rotary lever which is also adapted to be responsive to the changeover operation member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
199 words
A tape recorder having a driving mechanism for enabling tape rewinding at a higher speed and a lower speed comprising: a tape winding reel; a tape rewinding reel; a changeover operation member adapted to be set to effect rewinding of said tape; a fast-feed operation member adapted to effect feeding of said tape at said higher speed; a main switch adapted to set said driving mechanism for operation at said lower speed; a high-speed switch adapted to be actuated by said fast-feed operation member to set said driving mechanism for operation at said higher speed; a first rotary lever adapted to actuate said main switch in response to actuation of said first rotary lever by said changeover operation member; a second rotary lever adapted to be engaged by said changeover operation member when said changeover operation member is set to effect rewinding of said tape; and a tape driving member for transmitting a tape driving force to either said tape winding reel or said tape rewinding reel, said tape driving member being actuated by said second rotary lever to transmit a tape driving force to said tape rewinding reel in response to actuation thereof by said second rotary lever.
Claim 2
Dependent Claim
199 words
A tape recorder having a driving mechanism for enabling tape rewinding at a higher speed and a lower speed comprising: a tape winding reel; a tape rewinding reel; a changeover operation member adapted to be set to effect rewinding of said tape; a fast-feed operation member adapted to effect feeding of said tape at said higher speed; a main switch adapted to set said driving mechanism for operation at said lower speed; a high-speed switch adapted to be actuated by said fast-feed operation member to set said driving mechanism for operation at said higher speed; a first rotary lever adapted to actuate said main switch in response to actuation of said first rotary lever by said changeover operation member; a second rotary lever adapted to be engaged by said changeover operation member when said changeover operation member is set to effect rewinding of said tape; and a tape driving member for transmitting a tape driving force to either said tape winding reel or said tape rewinding reel, said tape driving member being actuated by said second rotary lever to transmit a tape driving force to said tape rewinding reel in response to actuation thereof by said second rotary lever.
Claim 3
Dependent Claim
27 words
A tape recorder as set forth in claim 1, wherein said changeover operation member and said fast-feed operation member comprise operation buttons that can be slidably activated.
Claim 4
Dependent Claim
23 words
A tape recorder as set forth in claim 1, wherein said first and second rotary levers are rotatably supported on the same shaft.
Claim 5
Dependent Claim
85 words
A tape recorder as set forth in claim 1, wherein said tape driving member comprises a third rotary lever engaged and rotated by said second rotary lever, a first friction roller suported on said third rotary lever and engaged with said tape winding reel for transmitting a tape driving force thereto, and a second friction roller supported on said third rotary lever and brought into engagement, by rotation of said third rotary lever, with said tape rewinding reel for transmitting a tape driving force thereto.
