[0054] The present invention provides a card reading and writing device 100.

[0055] Please refer to Figure 7 , in some embodiments of the card reading and writing device 100 of the present invention, the card reading and writing device 100 includes:

[0056] A housing 10, within which a card channel is formed;

[0057] A conveying mechanism 20, which is disposed within the housing 10 and is used for conveying the cards within the card channel;

[0058] An IC card reading and writing mechanism 30, which is movably disposed within the housing 10 so that at least a part of the IC card reading and writing mechanism 30 can enter and exit the card channel;

[0059] A magnetic stripe reading and writing mechanism 40, which is arranged in sequence with the IC card reading and writing mechanism 30 along the conveying direction of the card channel, and the magnetic stripe reading and writing mechanism 40 is movably arranged so that at least a part of the magnetic stripe reading and writing mechanism 40 can enter and exit the card channel;

[0060] A guiding member 50, which is disposed on one side of the card channel and extends along the conveying direction of the card channel; and

[0061] A side pressing mechanism 60, which is disposed on the other side of the card channel and is arranged opposite to the guiding member 50 to press the card towards the guiding member 50.

[0062] The card reading and writing device 100 proposed in this application includes a housing 10, a conveying mechanism 20 and a reading and writing mechanism disposed within the housing 10. A card channel is formed within the housing 10 for conveying cards. The conveying mechanism 20 is disposed within the housing 10 to drive the cards in the card channel to move forward. When a user uses the card reading device, they only need to insert the card into the card channel from the entry end, and then the conveying mechanism 20 can transport the card to the working position of the reading and writing mechanism, where the reading and writing mechanism performs information processing. In this embodiment, a guiding member 50 and a side pressing mechanism 60 are respectively disposed on both sides of the card channel. The guiding member 50 and the side pressing mechanism 60 both extend along the length direction of the card channel, and the guiding member 50 and the side pressing mechanism 60 are oppositely disposed to limit the card, so that the card moves along the guiding member 50 in the card channel under the drive of the conveying mechanism 20. Specifically, when the card enters the card channel from the entry end, the side pressing mechanism 60 presses against the side of the card opposite to the guiding member 50, causing the card to move towards the guiding member 50 and abut against the guiding member 50. At this time, when the conveying mechanism 20 drives the card to move forward, the card is stably moved to the position of the reading and writing mechanism under the limiting action of the side pressing mechanism 60 and the guiding member 50, and will not shake in the card channel, thereby ensuring that the magnetic head 42 of the reading and writing mechanism accurately aligns with the magnetic stripe of the card for information processing, improving the accuracy of card reading and writing.

[0063] Furthermore, in the card reading and writing device 100 proposed in this application, an IC card reading and writing mechanism 30 and a magnetic stripe reading and writing mechanism are provided. The magnetic stripe reading and writing mechanism 40 and the IC card reading and writing mechanism 30 are arranged in sequence along the conveying direction of the conveying mechanism 20. When a user inserts an IC card and a magnetic stripe card respectively, the conveying mechanism 20 transports the cards to the corresponding reading and writing mechanism positions according to the type of the inserted card to perform card reading and writing operations, thereby improving the applicability of the card reading and writing device 100.

[0064] Therefore, it can be understood that in the card reading and writing device 100 of the present invention, by respectively disposing a guiding member 50 for guiding the card to move forward and a side pressing mechanism 60 for pressing the card towards the guiding member 50 on both sides of the card channel of the conveying mechanism 20, the card moves along the guiding member 50 in the card channel under the drive of the conveying mechanism 20, avoiding the problem that the card deviates outside the predetermined trajectory when moving forward along the card channel. Therefore, the card reading and writing device 100 of the present invention enables the card to be accurately aligned with the reading and writing mechanism within the card channel by setting the side pressing mechanism 60 and the guiding member 50, improving the accuracy of card reading and writing of the card reading and writing device 100.

The elastic member 62 is disposed on a side of the side pressing member 61 facing away from the guiding member 50. With such a setting, when the card is placed between the guiding member 50 and the side pressing member 61, the side pressing member 61 is subjected to the top thrust of the card and transmits it to the elastic member 62, so that the elastic member 62 contracts to generate a reverse elastic holding force, thereby driving the side pressing member 61 to press the card so that the card abuts against the guiding member 50 and moves along the guiding member 50 under the drive of the conveying mechanism 20, improving the stability of the card movement.
