Tape feeder

1. A tape feeder which supplies electronic components to a board working machine, comprising:

a reel holding section at which a first reel around which a first tape that holds the electronic components is wound is held, and a second reel around which a second tape that holds the electronic components is wound, at different positions on a reel holding surface;

a feeder main body which feeds the first tape from the first reel to the board working machine, and automatically feeds the second tape from the second reel to the board working machine after the first tape is consumed; and

a movable mechanism which is provided between the reel holding section and the feeder main body, and allows the reel holding section to relatively move with respect to the feeder main body,

wherein the movable mechanism is capable of changing the position of the reel holding section with respect to the feeder main body between an upper position and a lower position, and is capable of changing the position of the reel holding section between a proximity position and a separation position at least at the lower position; wherein the movable mechanism includes a guide arm having a guide section that extends in parallel to the reel holding surface, and wherein the reel holding section is configured to be slidable between the proximity position and the separation position along the guide section; wherein an opening which extends along the sliding direction of the reel holding section is formed as the guide section in the guide arm, wherein one pair of grooves including a lower groove formed at a lower edge which defines the opening, and an upper groove formed at an upper edge which defines the opening, are formed at the opening, wherein the reel holding section includes one pair of rollers which are inserted into the opening of the guide arm, and wherein the position of the reel holding section with respect to the feeder main body is fixed when one of the one pair of rollers is fitted to the lower groove, and the other one is fitted to the upper groove.

2. The tape feeder according to claim 1 ,

wherein the guide arm is configured to be capable of moving in parallel between a position when the reel holding section is disposed at the upper position, and a position when the reel holding section is disposed at the lower position.

3. The tape feeder according to claim 1 ,

wherein the movable mechanism includes a first attachable and detachable section and a second attachable and detachable section which are selectively attachable and detachable due to the guide arm,

wherein the reel holding section is disposed at the upper position when the guide arm is attached to the first attachable and detachable section, and

wherein the reel holding section is disposed at the lower position when the guide arm is attached to the second attachable and detachable section.

4. The tape feeder according to claim 1 ,

wherein the one pair of grooves are respectively formed at one end portion and at the other end portion of the opening of the guide arm,

wherein the reel holding section is disposed at the proximity position when the one pair of rollers are fitted to the one pair of grooves which are formed at one end portion of the opening, and

wherein the reel holding section is disposed at the separation position when the one pair of rollers are fitted to the one pair of grooves which are formed at the other one end portion of the opening.

5. The tape feeder according to claim 1 ,

wherein the reel holding section includes a first holding section and a second holding section,

wherein the first holding section is configured to hold the first reel, and

wherein the second holding section is disposed further toward a far side from the feeder main body than the first holding section, and is configured to be capable of moving between a normal position at which the second reel is held and a retracted position which is close to the feeder main body and at which the second reel is not held.
