Nedium processing apparatus

Abstract

A medium process device (card reader 1) reading or writing information record medium comprises: insert opening (11a) front component (shade plate 11) supplies information record medium insert; the information record medium walks in a walking channel inside of the device body (12) from the insert opening (11); a curtain door (PIN curtain door 15) is arranged at the side end of the front component (11) of the device body relative to the walking channel entering / withdrawing and preventing the information recording medium from inserting into the device body (12); a dustproof component (dustproof plate 18) is arranged between the front component (11) and PIN curtain door (15) and seals the walking channel. Using the present invention, it can prevent card from retaining or prevent foreign body from mistaking to be inserted, have dustproof performance and security, and be easy to maintain and check.

Description

technical field [0001] The present invention relates to a medium processing device for reading or writing information on an information recording medium. Background technique [0002] Conventionally, various techniques for sealing the card insertion port of the card reader have been developed. For example, there are guillotine curtain doors, reversible curtain doors, PIN curtain doors, or dust-proof panels. This technology prevents a card from being inserted into the card slot of the card reader by mistake, or a foreign object from being inserted mischievously, and prevents dust from entering the card reader. [0003] The structure of the knife-type curtain door is that opening and closing components such as metal plates can be allowed to enter and exit from the card traveling passage up and down or left and right in the card traveling passage. The structure of the reversible curtain door is that a door that rotates when the card contacts (collision) is provided on the car...

AI Technical Summary

Problems solved by technology

[0005] However, the mechanism of the knife-type curtain door is complicated, and the increase in cost and the enlargement of the device cannot be avoided, and it is difficult to perform regular maintenance and inspection.

In addition, it is difficult to prevent the entry of dust even if the insertion of foreign objects can be prevented

The reversible curtain door is in contact with the hard revolving door when the card walking channel is open, so it will cause damage to the card, and it is difficult to carry out regular maintenance and inspection on its mechanism

There are also problems in the following aspects: the need for a gap for avoiding the revolving door, and the lack of dustproofness

The PIN curtain door can only partially seal the card passage, but cannot seal most of the card passage. In addition to lack of dust resistance, there are also safety concerns such as peeping into the device.

Although the dustproof board is excellent in dust resistance, it is generally made of soft materials, so it cannot be said to be effective against the wrong insertion of cards and the insertion of foreign objects.
