Abstract
Abstract Apparatus is disclosed for scanning and projecting a set of images carried by a filmstrip wherein the strip may be transported in either direction by a single control knob. Rotation of the control knob causes a main or first drive shaft to be moved to either a first or second position and to there respectively engage either second and third shafts. In turn, the second and third shafts are respectively coupled to take-up members about which the filmstrip may be wound.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
189 words
Apparatus for selectively driving a strip, said apparatus comprising: first and second driven members for selectively moving the strip, a shaft rotatable in opposite directions and having a first plurality of teeth, a rotatable drive member having means defining an opening therethrough and a second plurality of teeth extending into said opening, said drive member being mounted on said shaft with a part only of said first plurality of teeth and said second plurality of teeth being in engagement, and said drive member being translatably movable with respect to said shaft between a first position wherein said drive member engages said first driven member and to a second position wherein said drive member engages said second driven member, said shaft and said drive member cooperatively interfitting in a manner such that when said shaft is rotated in one of said opposite directions, said drive member is translatably moved to said first position to drivingly engage said first driven member and when said shaft is rotated in the other of said opposite directions, said drive member is translatably moved to said second position to drivingly engage said second driven member.
Claim 2
Dependent Claim
189 words
Apparatus for selectively driving a strip, said apparatus comprising: first and second driven members for selectively moving the strip, a shaft rotatable in opposite directions and having a first plurality of teeth, a rotatable drive member having means defining an opening therethrough and a second plurality of teeth extending into said opening, said drive member being mounted on said shaft with a part only of said first plurality of teeth and said second plurality of teeth being in engagement, and said drive member being translatably movable with respect to said shaft between a first position wherein said drive member engages said first driven member and to a second position wherein said drive member engages said second driven member, said shaft and said drive member cooperatively interfitting in a manner such that when said shaft is rotated in one of said opposite directions, said drive member is translatably moved to said first position to drivingly engage said first driven member and when said shaft is rotated in the other of said opposite directions, said drive member is translatably moved to said second position to drivingly engage said second driven member.
Claim 3
Dependent Claim
210 words
Apparatus for projecting images carried by a strip of information bearing medium, said apparatus comprising: means for projecting images from the strip, first and second driven means for directing the strip therebetween and past said means for projecting, a shaft rotatable in opposite directions and having a first plurality of engaging elements, a rotatable drive member having means defining an opening therethrough and a second plurality of engaging elements extending into said opening, said drive member being mounted on said shaft with a part only of said first plurality of engaging elements and said second plurality of engaging elements being in engagement, said drive member being translatably movable with respect to said shaft between a first position wherein said drive member engages said first driven member and a second position wherein said drive member engages said second driven member, said shaft and said drive member cooperatively interfitting in a manner such that when said shaft is rotated in one of said opposite directions, said drive member is translatably moved to said first position to drivingly engage said first driven member and when said shaft is rotated in the other of said opposite directions, said drive member is translatably moved to said second position to drivingly engage said second driven member.
Claim 4
Dependent Claim
210 words
Apparatus for projecting images carried by a strip of information bearing medium, said apparatus comprising: means for projecting images from the strip, first and second driven means for directing the strip therebetween and past said means for projecting, a shaft rotatable in opposite directions and having a first plurality of engaging elements, a rotatable drive member having means defining an opening therethrough and a second plurality of engaging elements extending into said opening, said drive member being mounted on said shaft with a part only of said first plurality of engaging elements and said second plurality of engaging elements being in engagement, said drive member being translatably movable with respect to said shaft between a first position wherein said drive member engages said first driven member and a second position wherein said drive member engages said second driven member, said shaft and said drive member cooperatively interfitting in a manner such that when said shaft is rotated in one of said opposite directions, said drive member is translatably moved to said first position to drivingly engage said first driven member and when said shaft is rotated in the other of said opposite directions, said drive member is translatably moved to said second position to drivingly engage said second driven member.
Claim 5
Dependent Claim
171 words
A drive mechanism comprising, first and second driven means, shaft mEans rotatable in opposite directions and having first engaging means, rotatable drive means having means defining an opening and second engaging means extending into said opening, said drive means being mounted on said shaft such that a portion only of said first and said second engaging means are in engagement, said drive means being translatably movable with respect to said shaft between a first position wherein said drive means engages said first driven means and a second position wherein said drive means engages said second driven means, said shaft and said drive member cooperatively interfitting in a manner such that when said shaft means is rotated in one of said opposite directions, said drive means is translatably moved to said first position to drivingly engage said first driven means and whereby when said shaft means is rotated in the other of said opposite directions said drive means is translatably moved to said second position to drivingly engage said second driven means.
Claim 6
Dependent Claim
171 words
A drive mechanism comprising, first and second driven means, shaft mEans rotatable in opposite directions and having first engaging means, rotatable drive means having means defining an opening and second engaging means extending into said opening, said drive means being mounted on said shaft such that a portion only of said first and said second engaging means are in engagement, said drive means being translatably movable with respect to said shaft between a first position wherein said drive means engages said first driven means and a second position wherein said drive means engages said second driven means, said shaft and said drive member cooperatively interfitting in a manner such that when said shaft means is rotated in one of said opposite directions, said drive means is translatably moved to said first position to drivingly engage said first driven means and whereby when said shaft means is rotated in the other of said opposite directions said drive means is translatably moved to said second position to drivingly engage said second driven means.
Claim 7
Dependent Claim
56 words
The drive mechanism of claim 3 wherein said first engaging means comprises a first plurality of engaging elements, wherein said second engaging means comprises a second plurality of engaging elements and wherein said drive means is mounted on said shaft such that a part only of said first and said second engaging elements are in engagement.
Claim 8
Dependent Claim
16 words
The drive mechanism of claim 3 wherein said first and second driven means are rotatably mounted.
Claim 9
Dependent Claim
68 words
The drive mechanism of claim 3 wherein said first engaging means includes a first plurality of teeth disposed about said shaft means, wherein said second engaging means includes a second plurality of teeth disposed about said opening and extending thereinto and wherein said drive means is mounted on said shaft means such that a part only of said first and said second plurality of teeth are in engagement.
