Abstract
Abstract A chassisless tape apparatus includes a housing on which the operative components of the tape transport are mounted and which includes protective ridges extending outwardly therefrom to protect the external operation mechanism recessed within the ridges. A slide assembly mounted to the housing and on which the play back head is mounted serves to advance the drive mechanism between play back and rewind positions as well as actuate an electrical switch for activating the electrical circuits thereby providing single slide control of the tape apparatus.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
273 words
A tape playback apparatus operator controlled by a single actuating slide assembly comprising: housing means for supporting a pair of spaced tape reel drive spindles, an electrical motor and selectively actuated drive means coupling said motor to said drive spindles for playback and rewind modes of operation; operator actuated slide plate means slidably mounted to said housing and including thereon a tape pickup head, said slide including an post coupled to said drive means for controlling said drive means between playback and rewind modes and electrical switch means mechanically coupled to said slide for actuation by said slide and electrically coupled to said electrical motor for actuation of said motor wherein said drive means includes a capstan bushing mounted to said housing means and including a capstan rotatably extending therethrough, a flywheel concentrically coupled to said capstan and a drive pulley mounted to said flywheel, means coupling said motor to said flywheel for the rotation of said flywheel and capstan and a pivoted carrier plate positioned to be pivoted about said capstan bushing and including a pair of spaced tension pulleys rotatably mounted thereto to support a drive belt extending around said drive pulley and said pair of spaced tension pulleys such that said drive belt extends between said spaced spindles, spindle drive pulleys mounted on said pair of spindles, respectively, so as to selectively engage said drive belt, and said post extending between said pivoted carrier plate for selectively pivoting said plate between a first position in which said drive belt engages a first spindle drive pulley and a second position in which said drive belt engages a second spindle drive pulley.
Claim 2
Dependent Claim
273 words
A tape playback apparatus operator controlled by a single actuating slide assembly comprising: housing means for supporting a pair of spaced tape reel drive spindles, an electrical motor and selectively actuated drive means coupling said motor to said drive spindles for playback and rewind modes of operation; operator actuated slide plate means slidably mounted to said housing and including thereon a tape pickup head, said slide including an post coupled to said drive means for controlling said drive means between playback and rewind modes and electrical switch means mechanically coupled to said slide for actuation by said slide and electrically coupled to said electrical motor for actuation of said motor wherein said drive means includes a capstan bushing mounted to said housing means and including a capstan rotatably extending therethrough, a flywheel concentrically coupled to said capstan and a drive pulley mounted to said flywheel, means coupling said motor to said flywheel for the rotation of said flywheel and capstan and a pivoted carrier plate positioned to be pivoted about said capstan bushing and including a pair of spaced tension pulleys rotatably mounted thereto to support a drive belt extending around said drive pulley and said pair of spaced tension pulleys such that said drive belt extends between said spaced spindles, spindle drive pulleys mounted on said pair of spindles, respectively, so as to selectively engage said drive belt, and said post extending between said pivoted carrier plate for selectively pivoting said plate between a first position in which said drive belt engages a first spindle drive pulley and a second position in which said drive belt engages a second spindle drive pulley.
Claim 3
Dependent Claim
77 words
The apparatus as defined in claim 1 wherein said housing means includes a slide receiving channel formed therein and wherein said slide is slidably extended into and supported by said channel, and said switch means includes a pair of spring contacts positioned within said housing means and spaced from one another with a conductive member includes spaced legs adapted to selectively engage said spring contacts in the playback and rewind modes of operation for actuating said motor.
