Abstract
A card reader has an opening at the base thereof in communication with the card insertion slot and forward of the IC contacts of the contacts carriage. When foreign materials such as coins are inserted into the card passageway, they are discharged through this bottom opening without contacting or causing damage to electronic contacts and without building up in the reader. Further, a blocking mechanism for the card passageway prevents foreign material such as coins from being inserted. When a read head senses the magnetic swipe of a card as the card is initially inserted, the blocking member is pivoted out of the way.
Description




BACKGROUND OF THE INVENTION




This invention relates in general to a card reader having arrangements that protect the card reader mechanism from the insertion of extraneous matter such as coins.




Card readers that accept cards which are inserted in a horizontal plane are known to include an opening at a bottom surface to divert extraneous foreign matter such as coins which might be inserted into the card receiving slot.




The type of opening provided along the bottom surface of such readers for horizontally inserted cards cannot be employed effectively for a card reader that is designed to accept cards which are inserted in a vertical plane.




One problem in these vertical card reading arrangements is that the coins or other foreign matter may hit and damage electronic components such as the IC contacts which are employed for reading the IC circuits on cards containing such.




The coins or other foreign matter may remain inside the card reader and can either be lodged at a point or built up to a point where they will damage the cards that are being inserted.




Accordingly, it is a major purpose of this invention to provide a card reader with a device that protects the reader from damage through the insertion of coins or other foreign matter.




It is a particular purpose of this invention to provide a card reader which is particularly adapted to provide such protection in designs where the card reader accepts cards that are manually inserted in a vertical plane.




It is a related purpose of this invention to provide the above objects in a simple configuration in which the unwanted foreign matters such as coins will be prevented from damaging the interior of the coin reader and will be blocked or discharged easily and with certainty.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




A First Embodiment (

FIGS. 1-3

)





FIGS. 1 through 3

show a manual card reader of an embodiment of the present invention. The embodiment described is an IC card reader having a magnetic head. Further, the present embodiment is configured in a vertical arrangement in which an IC card is vertically inserted.




The IC card reader has a pair of frames


1




a,




1




b


which are engaged with one another to provide a card passageway


2


. The card passageway


2


is a thin passageway tall enough to accept the card and which guides the IC card


3


in right and left directions as seen in

FIGS. 1 and 2

. At the front of the card passageway


2


(left side in FIG.


1


), the card inlet


4


includes a pair of tapered surfaces that taper out toward the outside of the device.




As shown in

FIG. 3

, the card inlet


4


is formed vertically. A pair of narrow inserting portions


4




a


and


4




c


are provided at top and bottom ends of the card inlet


4


. A slightly wider inserting portion


4




b


is provided between the narrower inserting portions


4




a


and


4




c.


Each of the narrower inserting portions


4




a


and


4




c


has a small gap (width) dimension corresponding to the thickness of the IC card


3


to accept the top portion and bottom edge of the IC card


3


. The narrower inserting portion


4




a


positioned at the top side has a length of about half of the entire length (vertical direction in the figure) of the card inlet


4


. The narrow inserting portion


4




c


at the bottom in the figure is extemely short. The wider d


1


inserting portion


4




b


is formed with a gap dimension slightly wider than the narrower inserting portion


4




a


so as to accommodate any warping or bending of the IC card


3


. The length of this portion


4




b


is close to half of the entire length (vertical direction in the figure) of the card inlet


4


.




In one embodiment, the inlet


4


has a height of approximately 55 mm, the portion


4




a


is approximately 29 mm long, and the portion


4




b


is approximately 24 mm long. The portion


4




c


is between one and two mm long. In that embodiment, the portion


4




a


is 1.2 mm wide, the portion


4




b


is 2.45 mm wide and the portion


4




c


is 1.45 mm wide. This is sufficient to accept most warped cards.




In the vicinity of the card inlet


4


, a magnetic head


5


for reading information in a magnetic stripe on the IC card


3


is positioned in the upper portion of the card passageway


2


. The magnetic head portion


5


also functions as a sensing means for sensing the insertion of the IC card


3


by detecting the presence of the magnetic stripe or magnetic data which is on the IC card


3


.




Further, a contacts carriage


6


that moves upon the insertion of the IC card


3


is positioned at the far end of the card passageway


2


in the card insertion direction (right side of FIG.


1


). The contacts carriage


6


is mounted so as to move back and forth in the card transporting direction with respect to an opening (not illustrated) provided at one of the pair of frames


1




a


and


1




b.


The carriage position shifts upwardly from a center line


2




a


in the card width direction (vertical direction in

FIG. 1

) of the card passageway


2


. The carriage is configured to move upon the insertion of the IC card


3


while controlling the position thereof relative to a predetermined reference surface


6




a.


More specifically, the contacts carriage


6


is mounted on the frame


1




b


by a parallel link mechanism


6




b,


consisting of two identical links, and arranged so as to move back and forth in the card transporting direction, and to stay parallel to the card passageway


2


. It is also capable of moving diagonally.




At the front side portion of the contacts carriage


6


in the card insertion direction, there is a key-shaped card contacting portion


6




c.


The front end of the IC card


3


contacts the portion


6




c,


which projects across the card passageway


2


. A plurality of contacts


6




d


are mounted on an elastic member and contact the contact pattern on the IC card


3


when the card is inserted. The contacts


6




d


which record and reproduce data by contacting the IC card


3


are arranged on one side of the surface of the contacts carriage in multiple lines along the card transporting direction.




Upon the manual insertion of the IC card, the front edge of the IC card


3


contacts the card contacting portion


6




c


of the contacts carriage


6


. This causes the contacts carriage to move parallel to the IC card


3


inside the card passage


2


shortening the distance that brings the points of the contacts


6




d


into contact with the contact pattern on the IC card


3


and to release the points of the contacts


6




d


from the contact pattern on the IC card


3


when moving in the reverse direction.




In addition, the contacts carriage


6


is energized in the card insertion direction (to the left in

FIG. 1

) of the card passage


2


by an energizing means of a coil spring


6




e


. When the IC card


3


is not inside the card passage


2


, the contacts carriage


6


stands by at a predetermined non-contact position.




On a sidewall surface of the frame


1




a


which faces the contacts carriage


6


, that is, a surface which faces a flat surface of the IC card


3


, an opening A for discharging foreign matter such as a coin C is formed. The opening A is provided, in case the card reader is constructed not in a vertical arrangement like the present embodiment but in a horizontal arrangement, to discharge foreign matter such as coin C inserted inside the card passageway


2


, and formed to let the card passageway


2


communicate to the outside.




The foreign matter discharge opening A is formed to have an opening area slightly larger than the size of the coin C having the largest diameter in the currently used coins; therefore, the coins C having different diameters inserted in the card passageway


2


are all discharged to the outside. Also, the foreign matter discharge opening A is positioned between the card inlet


4


and the contacts carriage


6


in the card insertion direction so that foreign matter inserted in the card passage is discharged outside before contacting electronic components such as IC contacts.




A frame bottom surface IC lower than the center line


2




a


of the card passage


2


is positioned so as to face the bottom edge of the IC card


3


. On a card-edge-facing wall


1




e


which constitutes the frame bottom surface


1




c,


a long, thin opening for discharging foreign matter B that extends along the card passage


2


is formed such that it lets the card passage


2


communicate with the outside via tapered surfaces


1




d,




1




d


provided at the card-edge-facing wall. The foreign matter discharge opening B is for a device of a vertical arrangement type like this embodiment. As illustrated in

FIG. 2

, the width dimension, W


2


, along the card passage


2


is set longer than the outer diameter, W


1


, of the coin C which has the largest diameter in the currently used coins. Thus, all kinds of coins C likely to be inserted in the card passage


2


will be discharged outside through the foreign matter discharge opening B.




Also, the foreign matter discharge opening B is formed to have a gap dimension, t


2


, equal to or larger than the gap dimension, t


1


, of the wider in inserting portion


4




b


of the card inlet


4


. Thus, all kinds of coins inserted in card passage


2


through the wider inserting portion


4




b


of the card inlet


4


are discharged outside.




The foreign matter discharge opening B is positioned between the card inlet


4


(left side in

FIG. 2

) and the contacts carriage


6


in the card insertion direction (right side in

FIG. 2

) so that foreign matter inserted in the card passage


2


is discharged toward the outside before contacting electronic components such as IC contacts.




In the IC card reader of this embodiment, foreign matter such as coins inserted in the card passage


2


through the card inlet


4


moves toward the opening B provided at the frame bottom surface


1




c


to which the foreign matter drops naturally, and the opening B is located before the contacts carriage


6


in the insertion direction; therefore, foreign matter will be discharged toward the outside of the device with certainty before contacting electronic components such as IC contacts.




When foreign matter such as coin C is inserted, it tends to come through the wider inserting portion


4




b


of the card inlet


4


. Since the foreign matter discharge opening B has a gap dimension, t


2


, that is larger than that of the widener inserting portion


4




b,


all foreign matter inserted to the device will be discharged outside through the foreign matter discharge opening B.




In this embodiment, the foreign matter discharge openings A and B are respectively provided at the side surface of the frame


1




a


and the bottom surface of the frame


1




b


. Therefore, no matter which arrangement type, vertical or horizontal, the IC card reader is, the foreign matter discharge opening A or B is provided on the frame wall surface to which foreign matter such as coin C, inserted into the device through the card inlet


4


, drops, thus discharging the foreign matter.




Moreover, in this embodiment, since the gap dimension, W


1


, of the foreign matter discharge openings A and B is set larger than the outer diameter W


1


of the coin C having the largest diameter in currently used coins, the coin C inserted inside the device as foreign matter will always be discharged outside.




Note that, although the above mentioned embodiment is an example of the preferred embodiments of the present invention, the present invention is not limited to this, but can be variously modified within the scope of the present invention. For example, the above mentioned embodiment is a manual card reader of a vertical arrangement type. However, it may be of a horizontal arrangement type or can be applied to a card reader in which cards are transported by a motor.




A Second Embodiment (

FIGS. 4-6

)





FIGS. 4 through 6

show a further embodiment of a card reader


101


. The card reader


101


includes a recess


104


for receiving cards


106


. A card


106


is inserted in the direction shown by arrow A. After being read, the card is removed by a reverse motion. The frame


102


has a card inlet slot


103


with a flared mouth to facilitate card insertion. When the card is fully inserted, it is inserted to the stop


107


at which the forward edge of the card contacts an engaging surface on the frame


102


. The card reader


101


includes a shutter member


105


to prevent coins and other extraneous items from entering the card reader. The recess


104


in the frame


2


facilitates hand insertion and removal. The portions


109


at both sides of the recess


104


aid in guiding insertion of the card.




The card inlet slot


103


extends around the recess


104


. The card


106


which is to be read by the card reader


101


may be an IC card having a magnetic stripe and/or an IC chip.




The card reader


101


includes features to read the information on the card. These features include a contact block


108


for the IC chip and a magnetic head


110


for reading magnetic data on the card


106


. The magnetic head


110


also functions as a detecting means for detecting the insertion of the card


106


by detecting the magnetic data on the card


106


.




The contact block that reads the IC chip on the IC card is positioned near the distal end of the inlet slot


103


close to the stop


107


.




The shutter member


105


normally closes the card inlet slot


103


. Magnetic head


110


is provided near one of the guide portions


109


in front of or proximal of the shutter


105


. The shutter


105


is rotatably mounted to a support shaft


114


which in turn is mounted to the frame


102


. As illustrated in

FIG. 6

, a coil spring


115


is attached to the shaft


114


. When the shutter


105


is unlocked and the card


106


is inserted, the shutter member


105


rotates against the spring force of the coil spring


115


to receive the card into the reader. When the card


106


is removed, the shutter member


105


returns to its original position by the force of the coil spring


115


.




The blocking part


128


of the shutter


120


is positioned to prevent coins and other foreign matter from entering when the card


106


is not inserted. The shutter actuating element


105


engages a tip of a plunger


117


. Plunger


117


is part of the disabling or canceling means


113


which, upon detection of the card, rotates the shutter out of the way so that the card can enter and which otherwise prevents shutter rotation when the card is not detected. The tip of the plunger


117


functions as a control to prevent the shutter actuating element


105


from moving into a disabling state when no card is present. The mechanism


113


for disabling the block can be constructed with a solenoid


116


inside the reader


101


. The plunger


117


attached to the solenoid


116


is moved back and forth by the solenoid


116


.




When the card


106


is not inserted, the tip of the plunger


117


engages a stopper in the shutter actuating element


105


so that the shutter is prevented from rotating. The shape of the stopper element


118


is not particularly limited as long as the shutter is prevented from rotating. The stopper element


118


locks the shutter only in the insertion direction.




Further, other than the stopper piece


118


, a stopper piece which locks the shutter member


105


in both the card insertion direction and the reverse direction may be used. The stopper piece is not limited to one which completely locks the shutter member


105


so as not to move at all, but some rotation may be allowed as long as it prevents foreign matter from entering.




The solenoid


116


is fixed to the frame


102


. A twisted coil spring


119


for returning the shutter member is provided around the plunger


117


to bias the plunger


117


in the projecting direction (to the right in

FIG. 4

) by pushing on a stopper ring


117


A on the plunger


117


. Therefore, the plunger


117


is projected by the spring force of the twisted coil spring


119


to return the shutter member when the solenoid


116


is not energized, i.e., at OFF state. On the other hand, when solenoid


116


is energized, i.e., at ON state, the plunger


117


is attracted into the solenoid


116


due to electromagnetic force, and tip of the plunger


117


and the stopper piece


118


are disengaged.




When the magnetic head


110


detects the presence of the card


106


having magnetic data, the solenoid is turned on and plunger


117


is attracted to the solenoid


116


. Accordingly, the stopper piece


118


is unlocked and the shutter member


105


becomes rotatable. When the card


106


is removed, the solenoid is turned off, the plunger


117


is returned to the original position and locks the stopper piece


118


again.




As illustrated in

FIG. 6

, a portion of the shutter member


105


is notched according to the shape of the solenoid


116


and the mounting position of the solenoid so that the shutter member


105


and the solenoid


116


main body do not interfere with each other to restrict the rotation of the shutter member


105


.




The manual card reader


101


is provided with a card locking member


120


which locks the card


106


so that it cannot be removed while data is being read by the contact block for IC card


108


. The card locking member


120


is arranged to move between a stand-by position


120




a


shown by a solid line in

FIG. 5 and a

detecting position


120




b


shown by a two dotted line. For example, until a detecting switch (not illustrated) detects that the card


106


has reached the card stopping position


107


, the card locking member stays at the stand-by position


120




a


. Upon detection of the card reaching the card stopping position


107


, the card locking member


120


is moved to the detecting position


120




b


through a solenoid (not illustrated) to lock the card


106


. Upon completion of data reading, the solenoid (not illustrated) is turned off so that the card locking member


120


returns to the stand-by position


120




a


to enable the card


106


to be removed.




In the frame


102


, foreign matter discharge openings


111


and


112


are provided at a plane


102




a


parallel to a reading surface


106




a


of the inserted card


106


and a plane


102




b


perpendicular to the reading surface


106




a


of the card


106


. For this reason, no matter which arrangement, horizontal or vertical, of the manual card reader


101


, any foreign matter such as a coin is inserted into the manual card reader


101


, can be discharged.




The operation of the manual card reader


101


configured as above will be described.




When the card


106


is not inserted, the shutter member


105


in the manual card reader


101


is locked from rotating by the stopper piece


118


and plunger


117


. Consequently, even if one tries to insert foreign matter other than cards into the manual card reader


101


through the card inlet


103


, the insertion will be prevented.




When the card


106


is inserted along the guide portions


109


, first the magnetic head


110


detects magnetic data and the solenoid


116


is electrified. With this, the plunger


117


is attracted to the solenoid, the engagement thereof with the stopper piece


118


is canceled, and the shutter member


105


becomes rotatable. The card


106


is inserted up to the card stopping position, pushing the shutter member


105


to open against the spring force of the twisted coil spring


115


.




When the detecting switch (not illustrated) detects that the card


106


has reached the card stopping position


107


, the card locking member


120


is moved by the solenoid (not illustrated) to the detecting position


120




b


to lock the card


106


in place. At this position, the contact block for IC card


108


contacts the card


106


to read data on the card. After data is read, the solenoid is turned off so that the card locking member


120


is returned to the stand-by position


120




a


to enable the card


106


to be removed.




Upon completion of data reading, the card


106


is removed. With the removal of the card


106


, the shutter member


105


is closed with the spring force of the twisted coil spring


115


. When the card


106


is removed completely from the manual card reader


101


, the solenoid is turned off and the plunger


117


is returned to the original position. The shutter member


105


is again locked with the engagement between the plunger


117


and the stopper piece


118


.




As described above, even when one tries to insert foreign matter other than the card


106


, since the shutter member


105


is locked from rotating, the foreign matter is prevented from entering the card reader


101


.




Although the above embodiment is an example of the preferred embodiments of the present invention, the present invention is not limited to this, but is variously modifiable within the scope of the invention.




For example, the shutter member


105


in this embodiment closes the portion of the card inlet


103


facing the recess portion of the card passageway. The card inlet


103


is wide compared to the guide portions


109


to accommodate a warped card. The shutter member may be extended to the guide portions


109


to close the entire card passageway.




The

FIG. 7

Shutter




A shutter member


121


illustrated in

FIG. 7

can be used as an example in which the shape of the shutter member


105


is modified. The shutter member


121


is arranged such that a rotation axis


125


of the shutter member


121


is positioned on the card incoming side to close the card inlet


103


. The same solenoid


116


and plunger


117


as those in the above embodiment can be used for the foreign matter insertion prevention by the shutter member


121


and cancellation of the previously mentioned prevention. In this case, in the same manner as the above embodiment, a stopper piece


122


is unlocked only when an appropriate card


106


is inserted, and the shutter member


121


becomes rotatable. The shutter member


121


is formed with support arms


123


that are tapered along the card insertion direction (the direction A) so that the shutter rotates clockwise as the arms ridge on the leading edge of the card


106


. For this reason, when the manual card reader


101


is installed in a horizontal arrangement, the shutter member


121


returns to the original position by gravity upon removal of the card


106


. The shutter member


121


can be configured to return to the original position with the spring force of a spring member


126


. By configuring the shutter member


121


to return to the original position using the spring member


126


, the shutter member


121


can be returned to the original position with certainty in the manual card reader


101


not only in a horizontal arrangement, but also in a vertical arrangement.




The detecting means for detecting the card insertion is not limited to the magnetic head


110


. For example, the detecting means may be configured with a triangle lever


124


as illustrated in FIG.


5


. The triangle lever


124


can be configured movable to the stand-by position shown by a two dotted line and returnable to the original position shown by a solid line according to the card


106


inserted and removed, and positioned at the guide portions


109


and before the shutter member


105


in the card insertion direction. When the triangle lever


124


moves, the insertion of the card


106


can be detected. Further, the detecting means of the triangle lever


124


can be combined with the detecting means of the magnetic head


110


.




Although the plunger


117


inserted in the solenoid


116


is engaged with the stopper


118


to lock the shutter member


105


in the above description, the stopper piece


118


may be omitted and the shutter member


105


be locked directly by the plunger


117


.




The shutter member


105


may also be opened and closed directly by an actuator such as a solenoid.




Recapitulation of the Invention




As understood in the above description, the present invention is configured such that, in a manual card reader of a vertical arrangement type, an opening for discharging foreign matter is provided at a bottom surface of a frame to which foreign matter such as coins inserted into the device by the card inlet drops, and the foreign matter discharge opening is positioned before a contacts carriage in the card insertion direction to discharge the foreign matter toward the outside of the device before the foreign matter touches electronic components such as IC contacts in the same manner as that of a horizontal arrangement type. Therefore, even when the present invention is applied to a card reader of a vertical arrangement type, foreign matter can be discharged easily and with certainty with a simple configuration of the device, thus increasing reliability of the card reader.




No matter which arrangement type, vertical or horizontal, the card reader is applied to, since the present invention is configured such that the foreign matter discharge opening is provided at the wall surface of the frame to which foreign matter such as coins inserted into the device through the card inlet drops and located before the contacts carriage in the card insertion direction, foreign matter is discharged toward the outside of the device before contacting electronic components such as IC contacts. Therefore, a card reader in a simple configuration can be provided in which foreign matter can be discharged easily and with certainty whether the card reader is arranged vertically or horizontally. Thus, reliability thereof is increased.




Further, the present invention provides a card inlet with narrow inserting portions for accepting top and bottom edges of the card and a wider inserting portion for accepting the warp of the card. The gap dimension of the foreign matter discharge opening is set equal to or larger than that of the wider inserting portion to discharge all the foreign matter inserted into the device toward the outside through the foreign matter discharge opening which has a gap dimension larger than that of the wider inserting portion. Therefore, foreign matter will be discharged with certainty.




Furthermore, the present invention is configured such that the width dimension of the foreign matter discharge opening is larger than all kinds of currently used coins to discharge all of those outside of the device if coins are inserted in the device as foreign matter. Therefore, when inserted foreign matter is a coin, the coin can be discharged with certainty.




The shutter member for preventing foreign matter such as coins from entering is located inside the recess. The disabling means for disabling the shutter is positioned so that when insertion of the appropriate card is detected, the disabling means is actuated to disable (unlock) the shutter and thus allow the card to be fully inserted. The shutter member is locked in a blocking position until an insertion attempt with the card is detected. Thus the present invention prevents foreign matter, other than the appropriate cards having magnetically encoded data, from being inserted by mistake or on purpose.




The shutter member is positioned between the recess inlet and the contact block for IC cards. Therefore, the contact block for the IC card, which block is important and is a fragile component, is protected by the shutter member.




A magnetic head for detecting magnetic data on the card is positioned at one of the side guide portions which guide the card to be inserted. This magnetic head is positioned proximal of the shutter member in the card insertion direction, so that when a card is inserted a detection of the magnetic stripe occurs before the card reaches the shutter member. Upon detection of the insertion of the card having magnetic data, the shutter member is disabled and the card can be fully inserted. But in the absence of detecting the card, the shutter member remains locked and foreign matter other than a card having magnetic data, is prevented from entering.




An opening for discharging foreign matter such as coins is provided. The opening is positioned inside the recess portion at one or more of two planes of the frame, which planes are parallel to and perpendicular to a reading surface of the card. Therefore, if the manual card reader is arranged in either a horizontal or a vertical position, foreign matter such as coins that are inserted into the reader will be discharged.




The disabling means for disabling the blocking by the shutter member includes a solenoid that actuates a plunger which normally locks the shutter member. When the plunger is actuated, it is removed from its blocking state and the locking of the shutter member is disabled and the shutter member will move out of the way of the appropriate card.




BRIEF DESCRIPTION




In brief, in one embodiment there is disclosed a vertical card reader having an opening at the base thereof positioned in communication with the card insertion slot and positioned forward of the IC contacts of the contacts carriage used in reading the card. Accordingly, when foreign materials such as coins are inserted into the card passageway through the inlet slot for the card, they are discharged through this bottom opening without contacting or causing damage to electronic contacts and without building up so as to cause damage to a card that is inserted.




In another embodiment, a blocking mechanism for the card passageway prevents foreign material such as coins from being inserted. In this embodiment, when a card is inserted, a read head is appropriately positioned to sense the magnetic swipe of the card as the card is initially inserted. When such sensing occurs, the blocking member is pivoted out of the way so the card can be fully inserted into the card passageway and properly read by the card reader.



Claims
  • 1. A card reader adapted to provide protection from insertion of foreign matter such as coins comprising:a frame having a front surface and a base surface, a card passageway having a card inlet at said front surface of said frame, said base surface being below said card inlet when the card reader is oriented to accept cards that are vertically inserted, a contacts carriage near a rear portion of said card passageway for contacting a card when said card is fully inserted, an opening in the base of said frame, said base opening being in communication with said card passageway at a location between said card inlet and said contacts carriage, insertion of foreign matter into said card inlet resulting in the foreign matter falling through said base opening without contacting said contacts; wherein said card inlet has a first portion having a thickness corresponding to a thickness of the IC card and a second wider portion with a thickness sufficiently larger to permit insertion of a warped card, a width dimension of said foreign matter discharge opening in the base of said frame being at least as large as the width of said second wider portion of said card inlet; wherein said contacts carriage is arranged to be shifted upwardly from a vertical center of said card passageway when an appropriate card is fully inserted in said reader.
  • 2. The card reader of claim 1 further comprising a sidewall opening in said card reader, said sidewall opening being in communication with said card passageway at a location between said contacts carriage and said inlet to said card passageway, whereby when said card reader is in a horizontal position, foreign matter or coins inserted into said card inlet will be discharged through said side passageway without contacting said contacts of said contacts carriage.
  • 3. The card reader of claim 1 wherein said foreign matter discharge opening in said base is larger than diameter a of largest anticipated foreign matter.
  • 4. The card reader of claim 1 wherein tapered portions are provided at said foreign matter discharge opening.
  • 5. The card reader of claim 1 wherein tapered portions are provided at said foreign matter discharge opening.
  • 6. The card reader of claim 2 wherein said card is an IC card, and said contacts of said contacts carriage elastically contact a contact pattern on said IC card, and said contacts carriage retaining said contacts and moving upon the insertion of said IC card so that said contacts are brought into contact with said contact pattern on said IC card.
  • 7. A card reader adapted to provide protection from the insertion of foreign matter such as coins comprising:a frame having a front surface and a base surface, a card passageway having a card inlet at said front surface of said frame, said base surface being below said card inlet when the card reader is oriented to accept cards that are vertically inserted, a head portion which records data on or reproduces data from a magnetic stripe on a card inserted into said passageway, said head portion being positioned above a center line of said card passageway, an opening in the base of said frame, said base opening being in communication with said card passageway at a location between said card inlet and said head portion, insertion of foreign matter into said card inlet resulting in the foreign matter falling through said base opening without contacting said contacts; wherein said card inlet has a first portion having a thickness corresponding to a thickness of the IC card and a second wider portion with a thickness sufficiently larger to permit insertion of a warped card, a width dimension of said foreign matter discharge opening in the base of said frame being at least as large as the width of said second wider portion of said card inlet; and wherein said contacts carriage is arranged to be shifted upwardly from a vertical center of said card passageway when an appropriate card is fully inserted in said reader.
  • 8. In a card reader having a recess portion for manually inserting a card through a card inlet into a card passageway, the improvement comprising:a shutter member having a normal blocking state and an unblocking state, said shutter member when in said blocking state being positioned across the card passageway near said inlet to prevent foreign matter from being inserted into said card passageway; and a means responsive to detection of the insertion of a card into said passageway to switch said shutter member into said unblocking state to permit passage of the card into its fully inserted position; wherein said inlet has a first portion having a thickness corresponding to a thickness of the IC card and a second wider portion with a thickness sufficiently larger to permit insertion of a warped card, a width dimension of said foreign matter discharge opening in the base of said frame being at least as large as the width of said second wider portion of said inlet; wherein said contacts carriage is arranged to be shifted upwardly from a vertical center of said card passageway when an appropriate card is fully inserted in said reader.
  • 9. The card reader of claim 8 wherein said card passageway extends along both sides of said recess to provide first and second guide portions for the card at both sides of said recess, and further comprising a magnetic head for detecting magnetic data on a card positioned at one of said guide portions to detect an inserted card prior to the inserted card abutting against said shutter member.
  • 10. The reader of claim 9 having a frame and further comprising at least one opening for discharging foreign matter at one of two planes which are parellel to and perpendicular to a reading surface of said card.
  • 11. The card reader of claim 9 wherein a switching means comprises a solenoid that drives a plunger which engages with said shutter for switching the state of said shutter.
