Card processing unit and card issuing device

摘要

A card processing unit that enables increasing a degree of freedom of a location of a communication antenna between pad rollers and simplifying a structure of the card processing unit itself. Specifically, a card processing unit equipped with a communication antenna for communicating with a non-contact IC card. The processing unit includes: two transfer rollers for transferring the non-contact IC card through contacting a surface of the non-contact IC card; pad rollers so placed as to face and bias themselves to the transfer rollers; fixed shafts protruding at both sides of each of the pad rollers in the axial direction for supporting the pad roller so as to be rotatable; and coil springs for biasing the fixed shafts at both the sides of the pad roller 16 in the axial direction so as to press the pad roller toward a corresponding one of the transfer rollers.

主权项

1. A card processing unit comprising:
a communication antenna configured to communicate with a non-contact IC card; two transfer rollers configured to transfer the non-contact IC card while contacting a surface of the non-contact IC card; pad rollers placed so as to face and bias themselves to the transfer rollers; two fixed shafts, each protruding in an axial direction from both sides of each pad roller, each fixed shaft supporting the corresponding pad roller so as to be rotatable; two compression coil springs provided for each fixed shaft, each pair of compression coil springs being configured to bias the corresponding fixed shaft in a direction so as to press the corresponding pad roller toward the corresponding transfer roller at the both sides in the axial direction of the corresponding pad roller; and a spring penetrating shaft provided for each compression coil spring, each spring penetrating shaft being fixed to a spring support plate for supporting each compression coil spring; wherein a top end of each compression coil spring contacts the corresponding fixed shaft and a bottom end of each compression coil spring contacts an upper surface of the corresponding spring support plate in a state that each compression coil spring is supported by the corresponding spring penetrating shaft, and thereby each pair of compression coil springs bias the corresponding fixed shaft upward to bias the corresponding pad roller in a direction for pressing the corresponding pad roller toward the corresponding transfer roller.
