Card reader and card lock mechanism

Abstract

Disclosed is a card reader and a card lock mechanism which are capable of preventing a prevention pawl for preventing drawing of a card from disengaging from a card in a state that drawing is prevented by the prevention pawl contacted with the card. In the card reader, a card lock mechanism (7) is structured to prevent drawing of the card from a card insertion port when the card is clogged in a card conveying passage. The card lock mechanism (7) includes a motor (14), a lock member (15) which is configured with prevention pawls (35a) contacted with a card and preventing drawing of the card and which is movable between a contact position where the prevention pawls (35a) are contacted with the card and a retreated position where the prevention pawls (35a) are retreated from the card conveying passage, and a power transmission mechanism (16) for transferring power of the motor (14) to the lock member (15). The power transmission mechanism (16) is configured with a final gear (25) arranged at a place closest to a lock member (15) side in a power transmission direction from the motor (14) to the lock member (15), and the lock member (15) is configured with a sector gear (35b) engaging with the final gear (25).

Description

technical field [0001] The present invention relates to a card reader for reading data recorded on a card or recording data to a card. Furthermore, the present invention relates to a card locking mechanism installed and used in the card reader. Background technique [0002] Conventionally, a card reader for reading data recorded on a card or recording data to a card has been widely used. In industries such as financial institutions that use card readers, criminals intentionally jam cards in card readers to illegally obtain cards, so-called phishing fraud, which is a major problem. Therefore, conventionally, a card reader having a card lock mechanism for preventing phishing fraud has been proposed (for example, refer to Patent Document 1). [0003] In the card reader described in Patent Document 1, the card lock mechanism has a lock lever that prevents the card from being pulled out of the card insertion slot. The locking handle has a substantially triangular-shaped lockin...

Problems solved by technology

[0006] In the card reader described in Patent Document 1, since the locking handle and the sector gear are connected through the connecting handle, there is a hidden danger that the connecting part between the locking handle and the connecting handle and the connecting part between the connecting handle and the sector gear shake.

Also, since the connecting handle is formed in a flat plate shape, if a large load is applied to the connecting handle, there is a possibility that the connecting handle may be deformed

According to the research of the inventors of the present application, in the card reader described in Patent Document 1, if the connecting part of the locking handle and the connecting handle and the connecting part of the connecting handle and the sector gear shake and the connecting handle deforms, there are obviously the following hidden dangers : Although the motor is stopped, the locking tooth is disengaged from the card in a state where it is in contact with the locking tooth and extraction is prevented, and the card is pulled out
