Abstract
Disclosed herein is a drive device designed to be detachably mounted on an existing video cassette recorder and playback machine and including a friction wheel designed to frictionally engage a channel tuning wheel already located on the machine as manufactured. The invention drive device includes a control knob constrained to rotate with the friction wheel via a shaft protruding through a housing of the device with the housing being detachably mounted on the machine with the friction wheel in frictional engagement with the existing tuning wheel.
Claims9
In a first device having a first housing with a first surface, said first surface having a first slot therein with a first rotary wheel protruding partially therethrough and second and third opposed elongated slots adjacent said first surface, an actuator detachably mountable on said first device and including:
- (a) a second housing including a bottom surface and an upstanding wall with an opening therethrough;
- (b) connection means on said bottom surface for releasably attaching said second housing to said first surface, said connection means comprising opposed tabs releasably engageable in said second and third slots, respectively;
- (c) a friction wheel with an actuator shaft protruding through said opening;
- (d) said first rotary wheel having a first peripheral surface which is frictionally engaged by a second peripheral surface on said friction wheel when said connector means attaches said second housing to said first surface, whereby rotation of said actuator shaft results in rotation of said friction wheel and first rotary wheel.
The invention claim 9, wherein said first rotary wheel comprises a station tuning wheel.
