Abstract

A groove for allowing passing of a component storage section during conveyance of a carrier tape having the component storage section protruding is formed in a tape conveyance path of a feeder. The groove is provided with a tape lower face biasing member which is pressed by the lower face of the carrier tape and is deformed downward when the carrier tape has the component storage section protruding until the carrier tape inserted from a tape insertion section reaches a rear side sprocket, and biases the lower face of the carrier tape when the carrier tape has the component storage section not protruding.

First claim

The invention claimed is:

1. A feeder comprising:
a feeder main body which has a tape insertion section formed in a rear portion of the feeder main body, the tape insertion section being configured to receive a carrier tape in which a component storage section storing a plurality of components is formed so as to protrude downward and a carrier tape in which a component storage section not protruding downward is formed;
a tape conveyance path which is provided between both side walls of the feeder main body so as to communicate with the tape insertion section in order to convey the carrier tapes toward a front side from a back side; and
a rear side sprocket which is rotatably provided in the feeder main body, has an engageable engagement protrusion in an engagement hole of the carrier tape inserted from the tape insertion section, and transmits the carrier tape along the tape conveyance path,
wherein a groove for allowing passing of the component storage section during the conveyance of the carrier tape having the component storage section protruding is formed in the tape conveyance path, and
wherein the groove is provided with a tape lower face biasing member which is pressed by a lower face of the carrier tape and is deformed downward when the carrier tape has the component storage section protruding, and biases the lower face of the carrier tape when the carrier tape has the component storage section not protruding, until the carrier tape inserted from the tape insertion section reaches the rear side sprocket.

2. The feeder according to claim 1 , further comprising:
an inlet pressing member which is provided in the feeder main body and presses the carrier tape inserted from the tape insertion section toward the tape conveyance path; and
a tape upper face biasing member which is provided in the inlet pressing member so as to face the tape lower face biasing member, and biases the upper face of the carrier tape inserted from the tape insertion section.

3. The feeder according to claim 2 ,
wherein the tape lower face biasing member and the tape upper face biasing member are made of elastic bodies, and
wherein an elastic modulus of the tape lower face biasing member is lower than an elastic modulus of the tape upper face biasing member.

4. The feeder according to claim 2 , further comprising:
a detection device which is provided in the feeder main body on a side closer to a downstream side of conveyance than the rear side sprocket in the tape conveyance path, and detects the carrier tape by a tip end of the carrier tape, inserted from the tape insertion section, abutting against the detection device,
wherein the tape upper face biasing member is provided up to at least an arrangement position of the detection device.

5. The feeder according to claim 4 , further comprising:
a rotatable lever which is provided in the feeder main body and raises the inlet pressing member when the carrier tape is inserted from the tape insertion section,
wherein the detection device outputs a rotation instruction signal of the lever for lowering the inlet pressing member when detecting the carrier tape.
