Abstract

A tape feeder includes: a feeder bottom support that rotatably holds a sprocket; and a tape presser mechanism that presses a carrier tape toward the feeder bottom support. The tape presser mechanism includes a tape presser that is at one end pivotally supported by the feeder bottom support and swingable to the feeder bottom support and that presses the carrier tape toward the sprocket while situated at a close position where the tape presser is closed to the feeder bottom support, and a tape presser operation member that is swingably attached to the feeder bottom support and that swings between a fixed position where the tape presser operation member presses the other end of the tape presser toward the feeder bottom support and an unfixed position where the other end of the tape feeder is released from pressure.

First claim

The invention claimed is:

1. A tape feeder that rotates a sprocket with feed pins of an outer circumference of the sprocket engaged with sprocket holes of a carrier tape to feed the carrier tape, the tape feeder comprising:
a feeder bottom support that rotatably holds the sprocket and that has a sprocket drive section that rotationally drives the sprocket; and
a tape presser mechanism that presses the carrier tape toward the feeder bottom support, wherein
the tape presser mechanism includes
a tape presser that is at one end pivotally supported by the feeder bottom support and swingable with respect to the feeder bottom support and that presses the carrier tape toward the sprocket while situated at a close position where the tape presser is closed with respect to the feeder bottom support, and
a tape presser operation member that is swingably attached to the feeder bottom support and that swings between a fixed position where the tape presser operation member presses the other end of the tape presser toward the feeder bottom support to fix the tape presser at the close position and an unfixed position where the other end of the tape feeder is released from pressure, and,

when the tape presser operation member is swung to the unfixed position from the fixed position, the tape presser operation member applies an upward force to the other end of the tape presser and lifts up the other end of the tape presser to form a carrier tape insertion space that enables insertion of the carrier tape between the tape presser and the feeder bottom support.

2. The tape feeder according to claim 1 , wherein an end of the tape presser operation member near the other end of the tape presser is forced downwardly by a biasing member provided between the feeder bottom support and the tape presser operation member, and the end of the tape presser operation member has a press portion that presses the other end of the tape presser and a lift portion that lifts the other end of the tape presser.

3. The tape feeder according to claim 2 , wherein the press portion of the tape presser operation member assumes a shape such that the press portion does not interfere with the tape presser which swings from the close position in a direction of opening with respect to the feeder bottom support while the tape presser operation member is situated at the unfixed position and that the press portion interferes with the tape presser which swings toward the close position from a position where the tape presser is opened with respect to the feeder bottom support while the tape presser operation member is situated at the fixed position.

4. The tape feeder according to claim 1 , wherein
the tape presser operation member includes a regulation portion, and
wherein when the tape presser operation member is in the unfixed position the tape presser is movable in a direction of opening with respect to the feeder bottom support to a position wherein the tape presser comes into contact with the regulation portion.

5. The tape feeder according to claim 2 , wherein the other end of the tape presser is free to pivot away from the sprocket and past the tape presser operation member.

6. A tape feeder that rotates a sprocket with feed pins of an outer circumference of the sprocket engaged with sprocket holes of a carrier tape to feed the carrier tape, the tape feeder comprising:
a feeder bottom support that rotatably holds the sprocket and that has a sprocket drive section that rotationally drives the sprocket; and
a tape presser mechanism that presses the carrier tape toward the feeder bottom support, wherein the tape presser mechanism includes
a tape presser that is at one end pivotally supported by the feeder bottom support and swingable with respect to the feeder bottom support and that presses the carrier tape toward the sprocket while situated at a close position where the tape presser is closed with respect to the feeder bottom support, and
a tape presser operation member that is swingably attached to the feeder bottom support and that swings between a fixed position where the tape presser operation member presses the other end of the tape presser toward the feeder bottom support to fix the tape presser at the close position and an unfixed position where the other end of the tape feeder is lifted up when the tape presser operation member applies an upward force to the other end of the tape feeder and is released from pressure, and, when the tape presser operation member is situated at the unfixed position, the tape presser and the feeder bottom support form a space for carrier tape insertion.
