T of tape withdrawn from the supply reel recorder indexing apparatus with a cumulative indication of the amoun

Claim 2

In a web moving apparatus including a web movement member which is selectively operative to move a web in either of two directions, apparatus for measuring the net amount of web movement in a first direction, comprising: first means operatively connected to said web movement member to provide a first output of an amount corresponding to movement of the web; second means connected to be responsive only to the amount of output of said first means corresponding to initial movement of said web in the first direction and to be nonresponsive to first means output corresponding to movement in the first direction of web which has been previously moved in the first direction, said second means thereby operative to provide a second output corresponding only to an output of said first means caused by initial movement of the web movement member in a first direction; and indicator means connected to be responsive to said second output to provide an indication which is a function of initial movement of the web movement member in said first direction only.

Claim 3

Apparatus as in claim 1, wherein: said second means includes a lost motion connection operative to provide said second output only in response to initial movement of said web movement member in said first direction and to provide no output in response to subsequent movement of said web movement member in said first direction to an extent previously moved in said first direction.

Claim 4

Apparatus as in claim 2, further comprising: reset means selectively operatively associated with said second means to cause said second output to be set to a predetermined initial indication.

Claim 5

Apparatus as in claim 1, wherein: said first means comprises a drive member connected for movement in response to movement of the web movement member; and said second means comprises a driven member which is selectively engaged by said drive member to be driven in a first direction by movement of said driving member in said first direction and not to be driven in a second direction by movement of said driving member in said second direction.

Claim 6

Apparatus as in claim 4, further comprising: means operatively engaging said driven member and resiliently urging said driven member in said second direction; brake means normally engaging said driven member to prevent movement of said driven member in said second direction in response to said urging means; and said brake means being selectively releasable to permit said driven member to be moved in said second direction by said urging means.

Claim 7

Apparatus as in claim 5, further comprising: a clutch disposed in the operative connection between the web movement member and said drive member; said clutch being selectively disengageable to disconnect said operative connection.

Claim 8

Apparatus as in claim 6, further comprising: actuating means operatively connected with said clutch and said brake means to cause selective concurrent disengagement of said clutch and releasing of said brake means, so that said driven member can be moved in said second direction by said urging means independently of movement of the web movement member.

Claim 9

Apparatus as in claim 7, wherein: said clutch includes a first member connected to be driven for rotation by the web movement member and a second member connected to rotate said drive member; said first member and second member being mounted for selective movement to an engaged position, wherein rotation of said first member is imparted to said second member, and to a disengaged position, where rotation of said first member is not imparted to said second member.

Claim 10

Apparatus as in claim 8, wherein: one of said first and second members is mounted for rotation on a shaft which is selectively translatable to place said first and second members in said engaged and disengaged positions; and said actuating means is selectively operative to translationally move said shaft for controlling said engagement of said first and second members.

Claim 11

Tape recording apparatus, comprising: a tape movement member operative for movement in either of two directions to accomplish corresponding movement of the recording tape in either a forward or a reverse direction; motion transmitting means operatively connected to be driven in either of two directions by movement of said tape movement member; one-way drive means having an input member connected for movement by said motion transmitting means and having an output member operative to move only in response to movement of said input member in a predetermined direction corresponding to forward movement of tape; means operatively connected to said output member to urge the output member in a direction opposite to said predetermined direction, brake means selectively engaging said output member to prevent said opposite direction movement of the output member, said brake means being selectively releasable to permit said opposite direction movement; and indicator means operative in response to movement of said output member to provide an indication of the amount of movement of said tape movement member in such predetermined direction.

Claim 12

Tape recording apparatus, comprising: a tape movement member operative for movement in either of two directions to accomplish corresponding movement of the recording tape in either a forward or a reverse direction; motion transmitting means operatively connected to be driven in either of two directions by movement of said tape movement member; one-way drive means having an input member connected for movement by said motion transmitting means and having an output member operative to move only in response to movement of said input member in a predetermined direction corresponding to forward movement of tape; means operatively connected to said output member to urge the output member in a direction opposite to said predetermined direction, brake means selectively engaging said output member to prevent said opposite direction movement of the output member, said brake means being selectively releasable to permit said opposite direction movement; and indicator means operative in response to movement of said output member to provide an indication of the amount of movement of said tape movement member in such predetermined direction.

Claim 13

Apparatus as in claim 10, wherein: said input member includes a driving member which moves in a predetermined path as said input member is moved by said motion transmitting means; said output member includes a driven member disposed in said predetermined path to be drivingly engaged by said driving member moving in said predetermined direction along said predetermined path; and said driving member being free to move out of said driving engagement with said driven member when moved in a direction opposite said predetermined direction.

Claim 14

Apparatus as in claim 11, wherein: said predetermined path has a certain extent, and said motion transmitting means is operative to move said input member a distance not exceeding the extent of said predetermined path in response to movement of said tape movement member which moves in a forward direction all of the tape in a tape supply available for recording.

Claim 15

Apparatus as in claim 11, wherein: said motion transmitting means includes selectively disengagable clutch means to enable said output mEmber and said input member to be moved in said opposite direction by said force applying means.

Claim 16

Apparatus as in claim 13, further comprising: actuating means operatively connected with said clutch means and with said brake means; said actuating means being selectively operable to concurrently disengage said clutch means and release said brake means.
