PROBLEM TO BE SOLVED: To provide a punching mechanism capable of reducing power consumption while making it possible to ensure discharging punch waste from a discharge passage.SOLUTION: A punching mechanism 5 includes: a punch blade 8 punching part of a card medium 2 to form a hole in the card medium 2; a punch drive source 9 driving the punch blade 8 to operate linearly; a discharge passage 11 for discharging punch waste 2a generated as a result of punching the card medium 2 by the punch blade 8; and an air-current generation mechanism 13 generating an air current in a direction of discharging the punch waste 2a from the discharge passage 11, within the discharge passage 11. The punch blade 8 extrudes the punch waste 2a to the discharge passage 11 at a time of punching the card medium 2, and the air-current generation mechanism 13 operates by power of the punch drive source 9 generated when the punch blade 8 forms the hole in the card medium 2 and generates the air current within the discharge passage 11. 【課題】排出路からパンチ屑を確実に排出することが可能であっても、消費電力を低減することが可能なパンチ機構を提供する。【解決手段】パンチ機構５は、カード状媒体２の一部を打ち抜いてカード状媒体２に孔を開けるパンチ刃８と、パンチ刃８を直線動作させるパンチ駆動源９と、パンチ刃８で打ち抜かれたパンチ屑２ａを排出するための排出路１１と、排出路１１からパンチ屑２ａが排出される方向への気流を排出路１１の内部に発生させる気流発生機構１３とを備えている。パンチ刃８は、カード状媒体２を打ち抜く際にパンチ屑２ａを排出路１１に押し出し、気流発生機構１３は、パンチ刃８がカード状媒体２に孔を開けるときのパンチ駆動源９の動力によって動作して、排出路１１の内部に気流を発生させる。【選択図】図２
