Description

  The present invention relates to a card reader that reads data recorded on a card and records data on the card.

  2. Description of the Related Art Conventionally, a so-called dip type card reader is known that manually operates a card to read data recorded on the card or record data on the card (see, for example, Patent Document 1). The card reader described in Patent Document 1 is formed with a card passing path through which a card passes. The card reader also includes an IC contact block having a plurality of IC contact springs and a lever member for preventing the card inserted into the card reader from being pulled out. The lever member is connected to a solenoid and is rotatable between a closed position for closing the card passage and an open position for opening the card passage.

  In the card reader described in Patent Document 1, when a card is inserted into the card reader and the external connection terminal of the IC chip formed on the card is in contact with the IC contact spring to perform data communication, the card reader When the card is pulled out from the card, there are problems that data to be recorded on the card is not recorded or data recorded on the card is erased. Therefore, in this card reader, when the card is inserted into the card reader and the external connection terminal of the IC chip and the IC contact spring are in contact with each other to perform data communication, the lever member disposed at the closed position causes the card to be Pull-out is prevented.

  Further, in the card reader described in Patent Document 1, the lever member includes a card contact portion that closes a part of the card passage when the lever member is disposed at the closed position. The back end surface of the card abutting portion is an inclined surface that inclines toward the back as it goes downward when the lever member is disposed at the closed position. Therefore, in this card reader, when the front end of the card pulled out from the card reader comes into contact with the back end surface of the card contact portion, the front end of the card is lifted and the force in the direction in which the lever member moves toward the closed position is Acting on the member makes it difficult for the lever member to move to the open position. Therefore, in this card reader, the lever member can reliably prevent the card inserted into the card reader from being pulled out.

JP 2006-122376 A

  As described above, in the card reader described in Patent Document 1, the lever member can reliably prevent the card inserted into the card reader from being pulled out. On the other hand, in the card reader described in Patent Document 1, after the card is inserted into the card reader, the lever member in the closed position can be automatically rotated to the open position for some reason such as a solenoid failure. If it runs out, it is difficult to pull out the card from the card reader. Further, if the card is forcibly pulled out from the card reader, the card may be damaged.

  That is, in the card reader described in Patent Document 1, when the lever member in the closed position cannot be automatically rotated to the open position after the card is inserted into the card reader, the user can remove the card. It is very difficult to pull out the card from the card reader without damaging it. In the card reader described in Patent Document 1, when the lever member in the closed position cannot be automatically rotated to the open position after the card is inserted into the card reader, the card is removed from the card reader. If it is forcibly pulled out, the card reader may be damaged.

  Therefore, an object of the present invention is to prevent the inserted card from being easily pulled out, and to damage the card when the pull-out preventing member that prevents the card from being pulled out automatically stops due to a failure or the like. It is an object of the present invention to provide a card reader that allows a card to be pulled out.

  In order to solve the above problems, a card reader of the present invention is a card reader that performs at least one of reading of data recorded on a card and recording of data on the card, and a card passage path through which the card passes, A pull-out prevention member configured to be movable between a closed position for closing the card passage path and an open position for opening the card passage path to prevent the card inserted into the card reader from being pulled out, and the closed position and the open position. And a movement mechanism for moving the pull-out prevention member between the positions, and the direction perpendicular to the direction of the card passing through the card passage and the thickness direction of the card passing through the card passage is defined as the card width direction. The card insertion direction side to the card reader is the back side, the card withdrawal direction side from the card reader is the front side, and one side of the card thickness direction is the first direction. When the other side in the card thickness direction is the second direction side, the pull-out preventing member closes a part of the card passage when the pull-out preventing member is disposed at the closed position. The card abutting portion moves toward the second direction when the pull-out preventing member moves from the open position to the closed position, and the card abutting portion has the pull-out preventing member disposed at the closed position. A first abutting surface on which the front end of the card inserted into the card reader can abut, and a second abutting surface connected to the first abutting surface and disposed on the second direction side of the first abutting surface. The first contact surface and the second contact surface are directed toward the second direction when viewed from the width direction of the card in a state where the pull-out preventing member is disposed at the closed position. The pull-out prevention part has an inclined surface that inclines toward the near side according to When viewed from the width direction of the card in a state where the card is placed in the closed position, the inclination angle of the first contact surface with respect to the card thickness direction is the inclination angle of the second contact surface with respect to the card thickness direction. It is characterized by being smaller than.

  In the card reader of the present invention, the front end of the card inserted into the card reader can come into contact with the card contact portion that closes a part of the card passage way when the pull-out prevention member is disposed at the closed position. A first abutment surface and a second abutment surface that is connected to the first abutment surface and is disposed on the second direction side of the first abutment surface are formed. The first abutment surface and the second abutment surface are directed toward the front side toward the second direction side when viewed from the width direction of the card in a state where the pull-out preventing member is disposed at the closed position. Although the inclined surface is inclined, the angle of inclination of the first abutting surface with respect to the thickness direction of the card when viewed from the width direction of the card in a state where the pull-out preventing member is disposed at the closed position is It is smaller than the inclination angle of the second contact surface with respect to the thickness direction. Therefore, in the present invention, the card inserted into the card reader can be easily used by using the first contact surface whose inclination angle with respect to the thickness direction of the card is small when the pull-out preventing member is disposed at the closed position. It becomes possible to prevent being pulled out.

  In the present invention, the card abutting portion moves toward the second direction when the pull-out preventing member moves from the open position to the closed position, and the first abutting surface has the pull-out preventing member at the closed position. When arranged, the inclined surface is inclined so as to go to the near side as it goes to the second direction side. Therefore, in the present invention, when the front end of the card pulled out from the card reader comes into contact with the first contact surface in a state where the pull-out prevention member is disposed at the closed position, the card contact portion moves toward the first direction. A direction force acts on the pull-out preventing member. Therefore, in the present invention, if the card inserted into the card reader is pulled out with a certain amount of force in a state where the pull-out preventing member is disposed at the closed position, the card contact portion moves toward the first direction side. It will be possible to start.

  Further, when the card contact portion starts to move toward the first direction side, the front end of the card that has been in contact with the first contact surface can be brought into contact with the second contact surface. Since the inclination angle of the second contact surface with respect to the card thickness direction is larger than the inclination angle of the first contact surface with respect to the card thickness direction, the front end of the card contacts the second contact surface. After that, it is possible to move the card abutting portion toward the first direction even if the card is pulled out with a relatively small force. As described above, in the present invention, if the card inserted into the card reader is pulled out with a certain amount of force in a state where the pull-out preventing member is disposed at the closed position, the card contact portion is directed toward the first direction side. Since it becomes possible to move the card, it is possible to pull out the card from the card reader without damaging the card when the pull-out preventing member stops moving automatically due to a failure of the moving mechanism or the like.

  In the present invention, the card reader includes a main body frame to which a moving mechanism is attached. The moving mechanism is disposed on the first direction side with respect to the card passage, and the inner end portion of the moving mechanism is fixed to the main body frame. It is preferable.

  With this configuration, since the front end side portion of the moving mechanism is not fixed to the main body frame, when the front end of the card pulled out from the card reader comes into contact with the first contact surface, the front end of the moving mechanism The side portion can be easily moved in the first direction, and the moving mechanism and the pull-out prevention member can be easily moved in the first direction. That is, when the front end of the card pulled out from the card reader comes into contact with the first contact surface, the card contact portion can be easily moved in the first direction. Therefore, it becomes possible to effectively prevent the card from being damaged when the card is pulled out from the card reader when the pull-out preventing member is not automatically moved due to a failure of the moving mechanism or the like. Further, it becomes possible to effectively prevent the card reader from being damaged.

  In the present invention, for example, the pull-out prevention member is configured to be rotatable between a closed position and an open position, and the moving mechanism includes a rotation center axis serving as a rotation center of the extraction prevention member, and a rotation center axis. And the axial direction of the rotation center axis coincides with the width direction of the card, and the rotation center axis is on the back side of the card contact portion and the card passing path. In addition to being disposed closer to the first direction, it is supported by the front end side portion of the shaft support member, and the back end side portion of the shaft support member is fixed to the main body frame.

  In this case, since the front end side portion of the shaft support member is not fixed to the main body frame, when the front end of the card pulled out from the card reader comes into contact with the first contact surface, the hand of the shaft support member It becomes easy to move the front end side portion in the first direction side, and it becomes easy to move the rotation center shaft and the pull-out prevention member in the first direction side. That is, when the front end of the card pulled out from the card reader comes into contact with the first contact surface, the card contact portion can be easily moved in the first direction. Therefore, it becomes possible to effectively prevent the card from being damaged when the card is pulled out from the card reader when the pull-out preventing member is not automatically moved due to a failure of the moving mechanism or the like. Further, it becomes possible to effectively prevent the card reader from being damaged.

  In the present invention, one end side of the rotation center shaft is supported by the shaft support member, and the main body frame supports the other end side of the rotation center shaft and the first direction side on the other end side of the rotation center shaft. It is preferable that a shaft support portion that restricts movement to the is formed. With this configuration, when the front end of the card pulled out from the card reader comes into contact with the first contact surface, the front end side portion of the shaft support member can be easily moved in the first direction side. When the force for pulling out the card is weak, it is possible to prevent the rotation center shaft and the pull-out preventing member from moving toward the first direction. Therefore, when the force to pull out the card is weak, it is possible to prevent the card abutting portion from moving toward the first direction, and as a result, the card inserted into the card reader can be easily It becomes possible to prevent being pulled out.

  In the present invention, the thickness direction of the card between the boundary portion between the first contact surface and the second contact surface and the surface on the second direction side of the card when the pull-out preventing member is disposed at the closed position. Is preferably substantially equal to the thickness of the card. With this configuration, when the card contact portion starts to move toward the first direction, the front end of the card that has been in contact with the first contact surface can be easily contacted with the second contact surface. Become.

  In the present invention, the width of the first contact surface in the thickness direction of the card when the pull-out preventing member is disposed at the closed position is, for example, wider than twice the thickness of the card.

  In the present invention, when viewed from the width direction of the card in a state where the pull-out preventing member is disposed at the closed position, the inclination angle of the second contact surface with respect to the thickness direction of the card is, for example, the thickness direction of the card 10 times or more and 11 times or less of the inclination angle of the first contact surface.

  In the present invention, the card pulling force when the card is pulled out from the card reader in a state where the card is inserted into the card reader and the pull-out preventing member is disposed at the closed position is, for example, 1.5 kg or more. It is less than 5kg. In this case, the card inserted into the card reader cannot be easily pulled out with the thumb and index finger in a state where the card is inserted into the card reader and the pull-out preventing member is disposed at the closed position. However, if the pull-out preventing member does not automatically move due to a failure of the moving mechanism or the like, the card can be pulled out by picking up the card with the thumb and index finger.

  In the present invention, the back end surface of the card contact portion is constituted by a first contact surface and a second contact surface, a boundary portion between the second direction end surface of the card contact portion and the second contact surface, and In addition, it is preferable that R processing is applied to a boundary portion between the first contact surface and the second contact surface. If comprised in this way, it will become possible to suppress generation | occurrence | production of the damage | wound of a card | curd when pulling out a card | curd when the drawing-out prevention member stops moving automatically.
