Abstract

Abstract An endless tape traveling device includes a substrate and a tape roll loaded stationary reel secured to the substrate. An endless tape is delivered from the innermost periphery of tape roll, through a slit provided across the width of the reel, toward the interior of the reel and, after running at high speed through a tape traveling path, wound around the the outer periphery of the tape roll.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 136 words
An endless tape traveling device comprising: a substrate; a stationary reel mounted on the substrate and having an annular body around which an endless tape roll is wound, and communicating means formed in the annular body to communicate the outer peripheral surface of the annular body to the inner peripheral surface thereof; a guide member mounted on the substrate within the interior of the annular body; and driving means for driving the endless tape such that an air film is formed between the innermost periphery of the tape roll and said outer peripheral surface of said annular body and the endless tape wound around the annular body is delivered from the innermost periphery of the tape roll, through the communicating means to the guide member, and taken up around the outer periphery of the tape roll.
Claim 2
Dependent Claim 136 words
An endless tape traveling device comprising: a substrate; a stationary reel mounted on the substrate and having an annular body around which an endless tape roll is wound, and communicating means formed in the annular body to communicate the outer peripheral surface of the annular body to the inner peripheral surface thereof; a guide member mounted on the substrate within the interior of the annular body; and driving means for driving the endless tape such that an air film is formed between the innermost periphery of the tape roll and said outer peripheral surface of said annular body and the endless tape wound around the annular body is delivered from the innermost periphery of the tape roll, through the communicating means to the guide member, and taken up around the outer periphery of the tape roll.
Claim 3
Dependent Claim 34 words
An endless tape traveling device according to claim 1, in which said tape driving means includes a member to cause the endless tape to travel at a high speed of more than 3 m/sec.
Claim 4
Dependent Claim 31 words
An endless tape traveling device according to claim 1, in which said tape driving means has a capstan and a pinch roll between which the endless tape is sandwiched for driving.
Claim 5
Dependent Claim 25 words
An endless tape traveling device according to claim 1, in which said guide member includes a pole mounted on the substrate in an inclined manner.
Claim 6
Dependent Claim 50 words
An endless tape traveling device according to claim 3, further including means for guiding the endless tape from said guide member to between said capstan and said pinch roll and guiding the endless tape from bewteen said capstan and said pinch roll toward the outermost periphery of the tape roll.
Claim 7
Dependent Claim 57 words
An endless tape traveling device according to claim 1, in which said communicating means has an opening provided across the width of said annular body, said opening curvilinearly extending from the outer periphery of the annular body and being open at the inner periphery of the annular body in a manner that a predetermined curvature is defined.
Claim 8
Dependent Claim 57 words
An endless tape traveling device according to claim 1, in which said communicating means has a slit provided across the width of said annular body, said slit curvilinearly extending from the outer periphery of the annular body and being open at the inner periphery of the annular body in a manner that a predetermined curvature is defined.
Claim 9
Dependent Claim 171 words
A tape traveling device comprising: a substrate; a stationary annular body mounted on the substrate and having an endless tape roll wound thereon and a communicating means for delivering the endless tape from the innermost periphery of the tape roll toward the interior of the annular body; rubber rolls arranged around the outer periphery of the annular body for contacting the lower side surface of the tape roll; a guide member mounted upon the substrate and within the inner periphery of the annular body for guiding the delivered endless tape toward the outside of the annular body; a tape traveling means adapted to guide the endless tape from the guide means toward the annular body to permit the endless tape to be wound around the outer periphery of the tape roll; and a tape driving means mounted within the tape traveling means for driving the endless tape such that an air film is formed between the innermost periphery of the tape roll and the outer peripheral surface of said annular body.
Claim 10
Dependent Claim 171 words
A tape traveling device comprising: a substrate; a stationary annular body mounted on the substrate and having an endless tape roll wound thereon and a communicating means for delivering the endless tape from the innermost periphery of the tape roll toward the interior of the annular body; rubber rolls arranged around the outer periphery of the annular body for contacting the lower side surface of the tape roll; a guide member mounted upon the substrate and within the inner periphery of the annular body for guiding the delivered endless tape toward the outside of the annular body; a tape traveling means adapted to guide the endless tape from the guide means toward the annular body to permit the endless tape to be wound around the outer periphery of the tape roll; and a tape driving means mounted within the tape traveling means for driving the endless tape such that an air film is formed between the innermost periphery of the tape roll and the outer peripheral surface of said annular body.
Claim 11
Dependent Claim 20 words
An endless tape traveling device as set forth in claim 4, wherein said guide member is stationary upon said substrate.
