Definitions
- the present invention relates to a medium stacker in which a plurality of card-shaped media is stored in a stacked state, and a medium feed device including the medium stacker.
- a card feed mechanism which includes a card stacker stored with a plurality of cards in a stacked state (see, for example, Patent Literature 1).
- the card feed mechanism described in Patent Literature 1 includes a support member which supports rear end sides in a feeding direction of cards stored in the card stacker at a predetermined height, a restriction member which is disposed in an inside of the card stacker at substantially the same height as the support member and restricts tip end sides in the feeding direction of the cards, a movable member structured to abut with the cards supported by the support member and lift rear end sides in the feeding direction of a plurality of the cards, a drive part structured to drive the movable member in an upper and lower direction that is a stacked direction of the cards, and a kick roller for feeding the lowest card of a plurality of the cards stored in the card stacker.
- the support member is provided with an inclined card support face, which is inclined with respect to the upper and lower direction, and a guide portion which is formed in a substantially perpendicular shape and is connected with a lower end of the inclined card support face.
- the movable member is disposed on an inner side of the support member. Further, the movable member is provided with a card abutting face which is abutted with rear end sides in the feeding direction of the cards when the movable member is moved upward by a drive force of the motor as a drive part.
- the card abutting face is formed in a step shape which is inclined with respect to the upper and lower direction.
- the card feed mechanism when the movable member is lifted, the rear end sides in the feeding direction of the cards abutted with the card abutting face are lifted. Therefore, even when a plurality of cards in a stacked state stored in the card stacker is in a stuck state on each other, mutually stuck cards can be separated from each other by lifting and lowering the movable member. Accordingly, in the card feed mechanism, even when the card feed mechanism is used under an environment where a plurality of stacked cards is easily stuck to each other, a plurality of the cards stored in the card stacker can be successively fed out one by one.
- At least an embodiment of the present invention provides a medium stacker capable of surely feeding out a card-shaped medium even when a frictional coefficient between a plurality of card-shaped media stored in a stacked state is high. Further, at least an embodiment of the present invention provides a medium feed device including the medium stacker.
- At least an embodiment of the present invention provides a medium stacker in which a plurality of card-shaped media is stacked and stored.
- the medium stacker includes a medium feed-out port which is formed at a lower end of the medium stacker and from which the lowest card-shaped medium of a plurality of the card-shaped media stored in the medium stacker is fed out.
- the medium stacker includes a front side plate structuring a front side face of the medium stacker, a rear side plate structuring a rear side face of the medium stacker, and at least an upper end side of the rear side plate is formed of an inclined part which is inclined to a rear side toward an upper side and the inclined part is contacted with the card-shaped media stored in the medium stacker.
- At least an upper end side of the rear sideplate structuring a rear side face of the medium stacker is formed of an inclined part which is inclined to a rear side toward an upper side and the inclined part is contacted with the card-shaped media stored in the medium stacker.
- the rear side plate structuring the rear side face of the medium stacker an entire region from a predetermined position in the upper and lower direction of the rear side plate to the upper end of the rear side plate is inclined to a rear side and the card-shaped media stored in the medium stacker are contacted with the inclined part.
- a load of a plurality of the card-shaped media stored on at least an upper end side of the medium stacker can be received by the inclined part of the rear side plate. Accordingly, in at least an embodiment of the present invention, a load applied to the lowest card-shaped medium of a plurality of the card-shaped media stored in the medium stacker can be reduced.
- At least an upper end side of the rear side plate is inclined to a rear side toward the upper side. Therefore, when the lowest card-shaped medium stored in the medium stacker is fed out from the medium feed-out port, a plurality of remaining card-shaped media stored in the medium stacker becomes easy to incline so that front sides of the card-shaped media are lifted as the lowest card-shaped medium is fed out from the medium feed-out port.
- a load of a plurality of the remaining card-shaped media stored in the medium stacker is hard to be applied to the lowest card-shaped medium as the lowest card-shaped medium is fed out from the medium feed-out port.
- a load applied to the lowest card-shaped medium stored in the medium stacker can be reduced and, in addition, when the lowest card-shaped medium stored in the medium stacker is to be fed out from the medium feed-out port, a load of a plurality of the remaining card-shaped media stored in the medium stacker is hard to be applied to the lowest card-shaped medium as the lowest card-shaped medium is fed out from the medium feed-out port.
- the medium stacker in at least an embodiment of the present invention is mounted, even when a frictional coefficient between a plurality of card-shaped media stored in a stacked state in the medium stacker is high, a frictional resistance between the lowest card-shaped medium and the card-shaped medium just above the lowest card-shaped medium stored in the medium stacker can be reduced and thus the card-shaped medium stored in the medium stacker can be surely fed out from the medium feed-out port.
- the entire region from a predetermined position in the upper and lower direction of the rear side plate to the upper end of the rear side plate is inclined to a rear side and thus, even when the number of the card-shaped media stored in the medium stacker is increased, a load of the increased card-shaped media can be received by the inclined part.
- a load applied to the lowest card-shaped medium stored in the medium stacker can be reduced and, as a result, a frictional resistance between the lowest card-shaped medium and the card-shaped medium contacting with the lowest card-shaped medium stored in the medium stacker can be reduced and the card-shaped medium stored in the medium stacker can be surely fed out from the medium feed-out port.
- the rear side plate is structured of a parallel part, which is parallel to the upper and lower direction and is a lower end side portion of the rear side plate, and an inclined part connected with an upper end of the parallel part .
- the front side plate is structured of a front side parallel part, which is parallel to the upper and lower direction and is a lower end side portion of the front side plate, and a front side inclined part which is connected with an upper end of the front side parallel part and is substantially parallel to the inclined part.
- a detection opening part for detecting a supply time of the card-shaped media to the medium stacker based on presence or absence of the card-shaped media in the medium stacker is formed at least one of a portion of the parallel part in a vicinity of a boundary between the parallel part and the inclined part and a portion of the front side parallel part in a vicinity of a boundary between the front side parallel part and the front side inclined part.
- the whole of the rear sideplate is the inclined part which is inclined to the rear side toward the upper side. According to this structure, a load of all card-shaped media stored in the medium stacker can be received by the rear side plate. Therefore, a load applied to the lowest card-shaped medium stored in the medium stacker can be reduced effectively. Further, according to this structure, when the lowest card-shaped medium stored in the medium stacker is fed out from the medium feed-out port, a plurality of remaining card-shaped media stored in the medium stacker becomes easy to incline so that front sides of the card-shaped media are lifted as the lowest card-shaped medium is fed out from the medium feed-out port.
- a load of a plurality of the remaining card-shaped media stored in the medium stacker is further hard to be applied to the lowest card-shaped medium which is fed out from the medium feed-out port.
- the card-shaped medium is, for example, a card which is accommodated in a bag.
- a bag in which a card is accommodated is, for example, a film bag made of polypropylene or the like, bags of stacked card-shaped media are easily contacted tightly and the card-shaped media are easy to be stuck on each other.
- a load applied to the lowest card-shaped medium stored in the medium stacker can be reduced and, in addition, when the lowest card-shaped medium stored in the medium stacker is to be fed out from the medium feed-out port, a load of a plurality of the remaining card-shaped media stored in the medium stacker is hard to be applied to the lowest card-shaped medium which is fed out from the medium feed-out port as the lowest card-shaped medium is fed out from the medium feed-out port. Therefore, even when a card-shaped medium is a card accommodated in a film bag made of polypropylene or the like, sticking of card-shaped media is prevented and the card-shaped medium stored in the medium stacker can be surely fed out from the medium feed-out port.
- the medium stacker in accordance with at least an embodiment of the present invention may be used in a medium feed device which includes a medium feed mechanism structured to feed the lowest card-shaped medium of the card-shaped media stored in the medium stacker from the medium feed-out port.

Description
- This is the U.S. national stage of application No. PCT/JP2013/084665, filed on Dec. 25, 2013. Priority under 35 U.S.C. §119(a) and 35 U.S.C. §365 (B) is claimed from Japanese Application No. 2013-051173, filed Mar. 14, 2013, the disclosures of which are incorporated herein by reference.
- The present invention relates to a medium stacker in which a plurality of card-shaped media is stored in a stacked state, and a medium feed device including the medium stacker.
- Conventionally, a card feed mechanism has been known which includes a card stacker stored with a plurality of cards in a stacked state (see, for example, Patent Literature 1). The card feed mechanism described in
Patent Literature 1 includes a support member which supports rear end sides in a feeding direction of cards stored in the card stacker at a predetermined height, a restriction member which is disposed in an inside of the card stacker at substantially the same height as the support member and restricts tip end sides in the feeding direction of the cards, a movable member structured to abut with the cards supported by the support member and lift rear end sides in the feeding direction of a plurality of the cards, a drive part structured to drive the movable member in an upper and lower direction that is a stacked direction of the cards, and a kick roller for feeding the lowest card of a plurality of the cards stored in the card stacker. - In the card feed mechanism described in
Patent Literature 1, the support member is provided with an inclined card support face, which is inclined with respect to the upper and lower direction, and a guide portion which is formed in a substantially perpendicular shape and is connected with a lower end of the inclined card support face. The movable member is disposed on an inner side of the support member. Further, the movable member is provided with a card abutting face which is abutted with rear end sides in the feeding direction of the cards when the movable member is moved upward by a drive force of the motor as a drive part. The card abutting face is formed in a step shape which is inclined with respect to the upper and lower direction. - In the card feed mechanism, when the movable member is lifted, the rear end sides in the feeding direction of the cards abutted with the card abutting face are lifted. Therefore, even when a plurality of cards in a stacked state stored in the card stacker is in a stuck state on each other, mutually stuck cards can be separated from each other by lifting and lowering the movable member. Accordingly, in the card feed mechanism, even when the card feed mechanism is used under an environment where a plurality of stacked cards is easily stuck to each other, a plurality of the cards stored in the card stacker can be successively fed out one by one.
- [PTL 1] Japanese Patent Laid-Open No. 2006-99224
- In the card feed mechanism described in
Patent Literature 1, the rear end sides in the feeding direction of cards are lifted by the movable member. Therefore, in the card feed mechanism, a large load due to weight of a plurality of the cards stored in the card stacker is easily applied to a tip end side in the feeding direction of the lowest card of a plurality of the cards stored in the card stacker. Accordingly, in the card feed mechanism, when a frictional coefficient between cards is high, a situation may be occurred that a card is unable to be fed out from the card stacker due to a frictional resistance between the lowest card and the card just above the lowest card. - In view of the problem described above, at least an embodiment of the present invention provides a medium stacker capable of surely feeding out a card-shaped medium even when a frictional coefficient between a plurality of card-shaped media stored in a stacked state is high. Further, at least an embodiment of the present invention provides a medium feed device including the medium stacker.
- To achieve the above mentioned, at least an embodiment of the present invention provides a medium stacker in which a plurality of card-shaped media is stacked and stored. The medium stacker includes a medium feed-out port which is formed at a lower end of the medium stacker and from which the lowest card-shaped medium of a plurality of the card-shaped media stored in the medium stacker is fed out. Further, when a feed direction side for the card-shaped medium which is fed out from the medium feed-out port is referred to as a front side and an opposite side in a feed direction of the card-shaped medium is referred to as a rear side, the medium stacker includes a front side plate structuring a front side face of the medium stacker, a rear side plate structuring a rear side face of the medium stacker, and at least an upper end side of the rear side plate is formed of an inclined part which is inclined to a rear side toward an upper side and the inclined part is contacted with the card-shaped media stored in the medium stacker.
- In the medium stacker in accordance with at least an embodiment of the present invention, at least an upper end side of the rear sideplate structuring a rear side face of the medium stacker is formed of an inclined part which is inclined to a rear side toward an upper side and the inclined part is contacted with the card-shaped media stored in the medium stacker. In other words, in the medium stacker in accordance with at least an embodiment of the present invention, in the rear side plate structuring the rear side face of the medium stacker, an entire region from a predetermined position in the upper and lower direction of the rear side plate to the upper end of the rear side plate is inclined to a rear side and the card-shaped media stored in the medium stacker are contacted with the inclined part. Therefore, according to at least an embodiment of the present invention, a load of a plurality of the card-shaped media stored on at least an upper end side of the medium stacker can be received by the inclined part of the rear side plate. Accordingly, in at least an embodiment of the present invention, a load applied to the lowest card-shaped medium of a plurality of the card-shaped media stored in the medium stacker can be reduced.
- Further, in at least an embodiment of the present invention, at least an upper end side of the rear side plate is inclined to a rear side toward the upper side. Therefore, when the lowest card-shaped medium stored in the medium stacker is fed out from the medium feed-out port, a plurality of remaining card-shaped media stored in the medium stacker becomes easy to incline so that front sides of the card-shaped media are lifted as the lowest card-shaped medium is fed out from the medium feed-out port. Accordingly, in at least an embodiment of the present invention, when the lowest card-shaped medium stored in the medium stacker is to be fed out from the medium feed-out port, a load of a plurality of the remaining card-shaped media stored in the medium stacker is hard to be applied to the lowest card-shaped medium as the lowest card-shaped medium is fed out from the medium feed-out port.
- As described above, in at least an embodiment of the present invention, a load applied to the lowest card-shaped medium stored in the medium stacker can be reduced and, in addition, when the lowest card-shaped medium stored in the medium stacker is to be fed out from the medium feed-out port, a load of a plurality of the remaining card-shaped media stored in the medium stacker is hard to be applied to the lowest card-shaped medium as the lowest card-shaped medium is fed out from the medium feed-out port. Therefore, in a device on which the medium stacker in at least an embodiment of the present invention is mounted, even when a frictional coefficient between a plurality of card-shaped media stored in a stacked state in the medium stacker is high, a frictional resistance between the lowest card-shaped medium and the card-shaped medium just above the lowest card-shaped medium stored in the medium stacker can be reduced and thus the card-shaped medium stored in the medium stacker can be surely fed out from the medium feed-out port.
- Further, in at least an embodiment of the present invention, the entire region from a predetermined position in the upper and lower direction of the rear side plate to the upper end of the rear side plate is inclined to a rear side and thus, even when the number of the card-shaped media stored in the medium stacker is increased, a load of the increased card-shaped media can be received by the inclined part. Therefore, according to at least an embodiment of the present invention, even when the number of the card-shaped medium stored in the medium stacker is increased, a load applied to the lowest card-shaped medium stored in the medium stacker can be reduced and, as a result, a frictional resistance between the lowest card-shaped medium and the card-shaped medium contacting with the lowest card-shaped medium stored in the medium stacker can be reduced and the card-shaped medium stored in the medium stacker can be surely fed out from the medium feed-out port.
- In at least an embodiment of the present invention, for example, the rear side plate is structured of a parallel part, which is parallel to the upper and lower direction and is a lower end side portion of the rear side plate, and an inclined part connected with an upper end of the parallel part . The front side plate is structured of a front side parallel part, which is parallel to the upper and lower direction and is a lower end side portion of the front side plate, and a front side inclined part which is connected with an upper end of the front side parallel part and is substantially parallel to the inclined part. A detection opening part for detecting a supply time of the card-shaped media to the medium stacker based on presence or absence of the card-shaped media in the medium stacker is formed at least one of a portion of the parallel part in a vicinity of a boundary between the parallel part and the inclined part and a portion of the front side parallel part in a vicinity of a boundary between the front side parallel part and the front side inclined part.
- In at least an embodiment of the present invention, it is preferable that the whole of the rear sideplate is the inclined part which is inclined to the rear side toward the upper side. According to this structure, a load of all card-shaped media stored in the medium stacker can be received by the rear side plate. Therefore, a load applied to the lowest card-shaped medium stored in the medium stacker can be reduced effectively. Further, according to this structure, when the lowest card-shaped medium stored in the medium stacker is fed out from the medium feed-out port, a plurality of remaining card-shaped media stored in the medium stacker becomes easy to incline so that front sides of the card-shaped media are lifted as the lowest card-shaped medium is fed out from the medium feed-out port. Therefore, a load of a plurality of the remaining card-shaped media stored in the medium stacker is further hard to be applied to the lowest card-shaped medium which is fed out from the medium feed-out port. As a result, even when a frictional coefficient between a plurality of card-shaped media stored in a stacked state in the medium stacker is high, a frictional resistance between the lowest card-shaped medium and the card-shaped medium just above the lowest card-shaped medium stored in the medium stacker can be further reduced and thus the card-shaped medium stored in the medium stacker can be further surely fed out from the medium feed-out port.
- In at least an embodiment of the present invention, the card-shaped medium is, for example, a card which is accommodated in a bag. In a case that a bag in which a card is accommodated is, for example, a film bag made of polypropylene or the like, bags of stacked card-shaped media are easily contacted tightly and the card-shaped media are easy to be stuck on each other. However, according to at least an embodiment of the present invention, a load applied to the lowest card-shaped medium stored in the medium stacker can be reduced and, in addition, when the lowest card-shaped medium stored in the medium stacker is to be fed out from the medium feed-out port, a load of a plurality of the remaining card-shaped media stored in the medium stacker is hard to be applied to the lowest card-shaped medium which is fed out from the medium feed-out port as the lowest card-shaped medium is fed out from the medium feed-out port. Therefore, even when a card-shaped medium is a card accommodated in a film bag made of polypropylene or the like, sticking of card-shaped media is prevented and the card-shaped medium stored in the medium stacker can be surely fed out from the medium feed-out port.
- The medium stacker in accordance with at least an embodiment of the present invention may be used in a medium feed device which includes a medium feed mechanism structured to feed the lowest card-shaped medium of the card-shaped media stored in the medium stacker from the medium feed-out port. According to the medium feed device, even when a frictional coefficient between a plurality of card-shaped media stored in a stacked state in the medium stacker is high, a frictional resistance between the lowest card-shaped medium and the card-shaped medium just above the lowest card-shaped medium stored in the medium stacker can be reduced and thus the card-shaped medium stored in the medium stacker can be surely fed out from the medium feed-out port.
- As described above, in the device on which the medium stacker in accordance with at least an embodiment of the present invention is mounted, even when a frictional coefficient between a plurality of card-shaped media stored in a stacked state in the medium stacker is high, the card-shaped medium stored in the medium stacker can be surely fed out from the medium feed-out port. Further, in the medium feed device in accordance with at least an embodiment of the present invention, even when a frictional coefficient between a plurality of card-shaped media stored in a stacked state in the medium stacker is high, the card-shaped medium stored in the medium stacker can be surely fed out from the medium feed-out port.

Therefore, when twocards 2 are fed out from thecard stacker 4 in an overlapped state, thecard 2 whose under face is abutted with thefeed roller 11 is conveyed to a front side and thecard 2 whose upper face is abutted with theseparation roller 13 is returned to a side of the card stacker 4 (in other words, to a rear side). - The
detection mechanism 7 is an optical type sensor having a light emitting element and a light receiving element. Thedetection mechanism 7 is provided for detecting a supply time ofcards 2 to thecard stacker 4 by detecting presence or absence ofcards 2 in thecard stacker 4. Specifically, thedetection mechanism 7 detects whether acard 2 is present or not on an upper end side in a region surrounded by theparallel part 4 g of thefront side plate 4 b, theparallel part 4 k of therear side plate 4 c, theright side plate 4 d and theleft side plate 4 e in thecard stacker 4 and thereby a supply time ofcards 2 to thecard stacker 4 is detected. - An upper end side of the
parallel part 4 g is, as shown inFIG. 3 , formed with adetection opening part 4 p for detecting presence or absence ofcards 2. In other words, thedetection opening part 4 p is formed in theparallel part 4 g in a vicinity of a boundary between theparallel part 4 g and theinclined part 4 h (specifically, just below a boundary between theparallel part 4 g and theinclined part 4 h).

Further, in this embodiment, rear end sides ofcards 2 stored in a region surrounded by theinclined part 4 h, theinclined part 4 m, theright side plate 4 d and theleft side plate 4 e in thecard stacker 4 are contacted with theinclined part 4 m. Therefore, according to this embodiment, a load ofcards 2 stored in a region surrounded by theinclined part 4 h, theinclined part 4 m, theright side plate 4 d and theleft side plate 4 e in thecard stacker 4 can be received by theinclined part 4 m. Accordingly, in this embodiment, a load applied to thelowest card 2 of a plurality of cards stored in thecard stacker 4 can be reduced. - In other words, when “W” represents the weight of all
cards 2 except thelowest card 2 of a plurality of thecards 2 stored in thecard stacker 4, “P” represents a load applied to thelowest card 2, “Q” represents a reaction force which is applied to thecards 2 by theinclined part 4 m and “μv” represents a frictional coefficient between theinclined part 4 m and thecards 2, in a case that theinclined parts card stacker 4, the load “P” applied to thelowest card 2 is expressed as follows. -
P=W - On the other hand, when the
inclined parts card stacker 4, a load “P” applied to thelowest card 2 is expressed as follows. -
P=W−Qsinθ−μvQcosθ - Therefore, according to this embodiment, a load applied to the
lowest card 2 of a plurality of thecards 2 stored in thecard stacker 4 can be reduced. - Further, in this embodiment, the upper end side of the
rear side plate 4 c is formed to be theinclined part 4 m which is inclined to a rear side toward the upper side. Therefore, when thelowest card 2 stored in thecard stacker 4 is fed out from the card feed-outport 4 j, a plurality of remainingcards 2 stored in thecard stacker 4 becomes easy to incline so that front sides of thecards 2 are lifted as thelowest card 2 is fed out from thecard feed port 4 j. Accordingly, in this embodiment, when thelowest card 2 stored in thecard stacker 4 is to be fed out from the card feed-outport 4 j, a load of a plurality of the remainingcards 2 stored in thecard stacker 4 is hard to be applied to thelowest card 2 as thelowest card 2 is fed out from the card feed-outport 4 j. - As described above, in this embodiment, a load can be reduced which is applied to the
lowest card 2 stored in thecard stacker 4 and, in addition, when thelowest card 2 stored in thecard stacker 4 is to be fed out from the card feed-outport 4 j, a load of a plurality of the remainingcards 2 stored in thecard stacker 4 is hard to be applied to thelowest card 2 as thelowest card 2 is fed out from the card feed-outport 4 j. Therefore, according to this embodiment, even when a frictional coefficient between a plurality ofcards 2 stored in a stacked state in thecard stacker 4 is high, a frictional resistance between thelowest card 2 and thecard 2 just above thelowest card 2 stored in thecard stacker 4 can be reduced and thus thecard 2 stored in thecard stacker 4 can be surely fed out from the card feed-outport 4 j. - Further, in this embodiment, the entire region from a predetermined position of the
rear side plate 4 c in the upper and lower direction to the upper end of therear side plate 4 c is inclined to a rear side and thus, even when the number of thecards 2 stored in thecard stacker 4 is increased, a load of the increasedcards 2 can be received by theinclined part 4 m. Therefore, according to this embodiment, even when the number of thecards 2 stored in thecard stacker 4 is increased, a load applied to thelowest card 2 stored in thecard stacker 4 can be reduced and, as a result, a frictional resistance between thelowest card 2 and thecard 2 contacting with thelowest card 2 stored in thecard stacker 4 can be reduced and thus thecard 2 stored in thecard stacker 4 can be surely fed out from the card feed-outport 4 j. - In this embodiment, a lower end side of the
front side plate 4 b is formed to be theparallel part 4 g and a lower end side of therear side plate 4 c is formed to be theparallel part 4 k. Therefore, according to this embodiment, a conventional card stacker (see, for example, Japanese Patent Laid-Open No. 2013-20283) in which the entirefront side plate 4 b and the entirerear side plate 4 c are parallel to the upper and lower direction can be attached to themain body part 5. Accordingly, in this embodiment, versatility of themedium feed device 1 can be enhanced. - Although the present invention has been shown and described with reference to a specific embodiment, various changes and modifications will be apparent to those skilled in the art from the teachings herein.
- In the embodiment described above, the
rear side plate 4 c is structured of theparallel part 4 k and theinclined part 4 m. However, the present invention is not limited to this embodiment. For example, the entirerear side plate 4 c may be formed of an inclined part which is inclined to a rear side toward the upper side. In other words, the entirerear side plate 4 c from its lower end to its upper end may be structured of an inclined part which is inclined to a rear side toward the upper side. In this case, therear side plate 4 c can receive a load of all thecards 2 stored in thecard stacker 4. Therefore, a load applied to thelowest card 2 stored in thecard stacker 4 can be reduced effectively. Further, in this case, when thelowest card 2 stored in thecard stacker 4 is fed out from the card feed-outport 4 j, a plurality of remainingcards 2 stored in thecard stacker 4 becomes easy to incline so that front sides of thecards 2 are lifted as thelowest card 2 is fed out from thecard feed port 4 j. Therefore, a load of a plurality of the remainingcards 2 stored in thecard stacker 4 is further hard to be applied to thelowest card 2 which is fed out from the card feed-outport 4 j. As a result, even when a frictional coefficient between a plurality ofcards 2 stored in a stacked state in thecard stacker 4 is high, a frictional resistance between thelowest card 2 and thecard 2 just above thelowest card 2 stored in thecard stacker 4 can be further reduced and thus thecard 2 stored in thecard stacker 4 can be further surely fed out from the card feed-outport 4 j. In this case, the entirefront side plate 4 b is also formed of an inclined part which is inclined to a rear side toward the upper side. An inclination angle of thefront side plate 4 b with respect to the upper and lower direction in this case may be the same as the inclination angle of therear side plate 4 c with respect to the upper and lower direction or may be different from each other. - Further, in the embodiment described above, the
rear side plate 4 c is structured of theparallel part 4 k and theinclined part 4 m. However, a guide part for guidingcards 2 to be stored in thecard stacker 4 may be formed so as to be connected with an upper end of theinclined part 4 m. In this case, the guide part is inclined to a rear side toward the upper side. Further, an inclination angle of the guide part with respect to the upper and lower direction is set to be larger than the inclination angle “θ” of theinclined part 4 m with respect to the upper and lower direction. Similarly, a guide part for guidingcards 2 to be stored in thecard stacker 4 may be formed so as to be connected with an upper end of theinclined part 4 h of thefront side plate 4 b. In this case, the guide part is inclined to a front side toward the upper side. - In the embodiment described above, the
detection opening part 4 p is formed on an upper end side of theparallel part 4 g of thefront side plate 4 b. However, the present invention is not limited to this embodiment. For example, instead of thedetection opening part 4 p, it may be structured that a detection opening part is formed on an upper end side of theparallel part 4 k of therear side plate 4 c and a detection opening part is formed at a portion corresponding to the detection opening part on a rear end side of theright side plate 4 d. In this case, a light emitting element and a light receiving element are disposed so that an optical axis of a light directing from the light emitting element to the light receiving element structuring thedetection mechanism 7 passes the detection opening part of therear side plate 4 c and the detection opening part of theright side plate 4 d. Further, in addition to thedetection opening part 4 p and the detection opening part formed on the front end side of theright side plate 4 d, it may be structured that a detection opening part is formed on an upper end side of theparallel part 4 k and a detection opening part is formed on a rear end side of theright side plate 4 d. - In the embodiment described above, the
card feed mechanism 6 includes thefeed roller 10 structured to abut with thelowest card 2 of a plurality ofcards 2 stored in thecard stacker 4 so as to feed out thelowest card 2 to a front side. However, the present invention is not limited to this embodiment. For example, thecard feed mechanism 6 may include, instead of thefeed roller 10, a pawl member structured to abut with a rear end face of thelowest card 2 stored in thecard stacker 4, a pawl member drive mechanism for driving the pawl member and the like. In a case that the thickness of acard 2 is thin and thus the rigidity of thecard 2 is low, it is preferable that thecard 2 stored in thecard stacker 4 is fed out by thefeed roller 10. On the other hand, in a case that the thickness of acard 2 is thick and thus the rigidity of thecard 2 is high, it is preferable that thecard 2 stored in thecard stacker 4 is fed out by a pawl member. - In the embodiment described above, the
card stacker 4 is detachably attached to themain body part 5. However, the present invention is not limited to this embodiment. For example, thecard stacker 4 may be fixed to themain body part 5. For example, thebottom plate 4 a, thefront side plate 4 b, therear side plate 4 c, theright side plate 4 d and theleft side plate 4 e may be integrally formed with a frame of themain body part 5. - In the embodiment described above, the
card 2 is a bagged card, in other words, a card is accommodated in a bag. However, thecard 2 may be a card made of vinyl chloride, a PET card, a paper card or the like which is not accommodated in a bag. Further, in the embodiment described above, thecard 2 is formed in a substantially rectangular shape but thecard 2 may be formed in a substantially square shape. Further, in the embodiment described above, a member for increasing a contact resistance of theinclined part 4 m with acard 2 may be fixed to a front face of theinclined part 4 m. For example, a felt or the like may be fixed to a front face of theinclined part 4 m. - While the description above refers to particular embodiments of the present invention, it will be understood that many modifications may be made without departing from the spirit thereof. The accompanying claims are intended to cover such modifications as would fall within the true scope and spirit of the present invention.
- The presently disclosed embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, rather than the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
