Optical fiber cutter

An optical fiber cutter that cleaves a part of an optical fiber, the optical fiber cutter comprising:

• a main body;
• an openable and closable clamp attached to the main body and configured to hold the optical fiber;
• and
• a movable blade configured to scratch the optical fiber held by the clamp, wherein
• a scrap collection mechanism configured to collect scraps of the cleaved optical fiber is further provided, and
• the scrap collection mechanism includes a case configured to accommodate the scraps, and a lid configured to open and close with respect to the case in conjunction with an opening and closing operation of the clamp, wherein
• the scrap collection mechanism further includes:
• a rotating roller provided in the case and including an upper roller pivotally supported on the lid and a lower roller pivotally supported within the main body, the lower roller being provided with a feed-out portion;
• and
• a driver configured to transmit a rotational force of the clamp to the lid and the rotating roller, wherein
• the rotating roller is configured to hold and feed out the scraps in a direction away from the clamp by sandwiching the scraps between the upper roller and the feed-out portion of the lower roller, wherein
• the driver transmits a closing operation of the clamp to the lid and does not transmit the closing operation to the rotating roller, wherein
• the driver includes a drive lever configured to interlock with the clamp, and a first gear configured to rotate according to an operation of the drive lever,
• the rotating roller integrally includes a second gear at one end of the rotating roller, and
• the first gear moves toward the second gear and is directly or indirectly engaged with the second gear according to the operation of the drive lever interlocked with the opening operation of the clamp, and moves toward an opposite side of the second gear and is disengaged from the second gear according to an operation of the drive lever interlocked with the closing operation of the clamp.
