Abstract

This apparatus provides a guide for card readers which is suitable for reading credit cards and the like. The reader is provided with a slot for receiving the card. A magnetic head or other device suitable for reading the encoded data on the card is positioned on one side of the slot. A roller clamp is pivotally mounted on the opposite side of the slot, and is urged into contact with an inserted card by a spring. An extension of the pivoted roller clamp protrudes through the top or upper surface of the card reader and when a card is inserted in the slot, slight hand pressure on the protrusion of the pivoted roller clamping member causes the roller clamp to be deflected permitting easy entry of the card in the reader.

Guide and Positioning Device for Card Reader

This apparatus provides a guide for card readers which is suitable for reading credit cards and the like. The reader is provided with a slot for receiving the card. A magnetic head or other device suitable for reading the encoded data on the card is positioned on one side of the slot. A roller clamp is pivotally mounted on the opposite side of the slot, and is urged into contact with an inserted card by a spring. An extension of the pivoted roller clamp protrudes through the top or upper surface of the card reader and when a card is inserted in the slot, slight hand pressure on the protrusion of the pivoted roller clamping member causes the roller clamp to be deflected permitting easy entry of the card in the reader. As soon as contact with the extension is removed, the pivoted roller clamp is urged into contact by the restoring force of the spring. The roller clamp urges the card into engagement with the reading head mounted in the opposite wall, and maintains intimate contact between the card and the head as the card is advanced through the reader. The roller clamp includes a ball journaled in the main frame member of the roller clamp assembly. Thus, only rolling friction is presented to the card as it is moved through the reader past the reading head.
