       [0002]    At least an embodiment of the present invention relates to a card conveying mechanism structured to convey a card. Further, at least an embodiment of the present invention relates to a card issuing device which includes the card conveying mechanism. 
       BACKGROUND 
       [0003]    Conventionally, a card issuing device structured to issue a card in which predetermined information is recorded has been known (see, for example, Patent Literature 1). The card issuing device described in Patent Literature 1 includes a card reader part structured to perform reproduction and the like of information recorded in a card, a plurality of card stack parts in which cards before issue are stacked and accommodated, a card turning part in which a card is turned, and a card conveyance part structured to convey a card between the card reader part, the plurality of the card stack parts and the card turning part.

       PATENT LITERATURE 
       [0005]    [PTL 1] Japanese Patent Laid-Open No. 2007-41635 
         [0006]    The card issuing device described in Patent Literature 1 includes the card conveyance part and thus a card can be conveyed in a horizontal direction (specifically, in a short-side direction of a card). Further, since the card issuing device includes the card turning part, a longitudinal direction of a card can be inclined with respect to the horizontal direction by utilizing the card turning part and, therefore, various processes can be performed on the card. However, in the card issuing device, the card conveyance part having the carriage and the card turning part having the attaching member are separately provided and placed on the main body base and thus an area of the main body base is large and, as a result, installation area of the card issuing device becomes wide. 
       SUMMARY 
       [0007]    Therefore, in view of the problem described above, at least an embodiment of the present invention provides a card conveying mechanism capable of reducing an installation area of a host apparatus to which the card conveying mechanism is mounted even when a card is capable of being conveyed in a horizontal direction, a card is capable of being set in parallel to the horizontal direction, and a card is capable of being inclined with respect to the horizontal direction. Further, at least an embodiment of the present invention provides a card issuing device including the card conveying mechanism. 
         [0008]    To achieve the above, at least an embodiment of the present invention provides a card conveying mechanism including a card holding part having a drawing and sending-out mechanism structured to perform drawing and sending out a card, the card holding part being configured to temporarily hold the card in its inside, a drawing and sending-out drive mechanism structured to drive the drawing and sending-out mechanism, a carriage on which the card holding part is mounted, a carriage drive mechanism structured to linearly move the carriage in a horizontal direction which is perpendicular to a drawing direction of the card into the card holding part, and a turning mechanism structured to turn the card holding part with respect to the carriage with the moving direction of the carriage as an axial direction of turning. 
         [0009]    The card conveying mechanism in at least an embodiment of the present invention includes a carriage drive mechanism structured to linearly move the carriage on which the card holding part is mounted in a horizontal direction and a turning mechanism structured to turn the card holding part with respect to the carriage with the moving direction of the carriage as an axial direction of turning. Therefore, according to at least an embodiment of the present invention, a card held by the card holding part is capable of being conveyed in the horizontal direction, and a card held by the card holding part is capable of being set in parallel to the horizontal direction and being inclined with respect to the horizontal direction. Further, in at least an embodiment of the present invention, the card holding part mounted on the carriage is linearly moved in the horizontal direction and is turned with the moving direction of the carriage as an axial direction of turning. Therefore, in comparison with a case that a card holding part linearly moved in the horizontal direction and a card holding part turned with the moving direction of the carriage as an axial direction of turning are separately provided from each other, the size of the card conveying mechanism can be made small and an installation area of the card conveying mechanism can be reduced. Accordingly, in at least an embodiment of the present invention, even when a card can be conveyed in the horizontal direction and a card can be set in parallel to the horizontal direction or inclined with respect to the horizontal direction, an installation area of a host apparatus on which the card conveying mechanism is mounted can be reduced. 
         [0010]    In at least an embodiment of the present invention, it is preferable that the card conveying mechanism includes two or more card holding parts which are disposed so as to overlap with each other in an upper and lower direction and, when the card holding parts are turned to predetermined positions by the turning mechanism, the card is capable of being transferred between the card holding parts in the upper and lower direction. According to this structure, a card is capable of being conveyed in an upper and lower direction. 
         [0011]    In at least an embodiment of the present invention, it is preferable that two or more card holding parts are mounted on a common carriage so as to overlap in the upper and lower direction. According to this structure, in comparison with a case that carriages on which each of two or more card holding parts is mounted are individually provided, the structure of the card conveying mechanism can be simplified. 
         [0012]    In at least an embodiment of the present invention, it is preferable that the card conveying mechanism includes a first card holding part and a second card holding part as the card holding part, the turning mechanism includes one turning motor which is a drive source and, when the turning motor is rotated, the first card holding part and the second card holding part are turned together. According to this structure, the first card holding part and the second card holding part can be turned by one turning motor and thus the structure of the turning mechanism can be simplified. Further, according to this structure, alignment of the first card holding part with the second card holding part can be performed by controlling the one turning motor when a card is transferred between the first card holding part and the second card holding part in the upper and lower direction. Therefore, the card conveying mechanism is easily controlled when a card is conveyed in the upper and lower direction. 
         [0013]    In at least an embodiment of the present invention, for example, the turning mechanism includes a first turning pulley which is fixed to a turnable shaft fixed to the first card holding part, a second turning pulley which is fixed to a turnable shaft fixed to the second card holding part, and a turning belt which is stretched over the first turning pulley and the second turning pulley. When the turning motor is rotated, the turning belt is turned and thereby the first card holding part and the second card holding part are turned together. 
         [0014]    In at least an embodiment of the present invention, it is preferable that the card conveying mechanism includes, as the card holding part, a first card holding part and a second card holding part, the first card holding part includes a first drawing and sending-out mechanism as the drawing and sending-out mechanism, and the second card holding part includes a second drawing and sending-out mechanism as the drawing and sending-out mechanism. The drawing and sending-out drive mechanism includes one drawing and sending-out motor which is a drive source and, when the drawing and sending-out motor is rotated, the first drawing and sending-out mechanism and the second drawing and sending-out mechanism perform a drawing operation or a sending-out operation of the card. According to this structure, a drawing operation or a sending-out operation of the card can be performed by the first drawing and sending-out mechanism and the second drawing and sending-out mechanism by using the one drawing and sending-out motor and thus a structure of the drawing and sending-out drive mechanism can be simplified. Further, according to this structure, a sending-out operation of a card by the first drawing and sending-out mechanism and a drawing operation of the card by the second drawing and sending-out mechanism can be easily synchronized with each other, and a sending-out operation of a card by the second drawing and sending-out mechanism and a drawing operation of the card by the first drawing and sending-out mechanism can be easily synchronized with each other. Therefore, when performing transfer of a card between the first card holding part and the second card holding part in the upper and lower direction, a card can be easily and smoothly transferred between the first card holding part and the second card holding part. 
         [0015]    In at least an embodiment of the present invention, for example, the drawing and sending-out drive mechanism includes a first drawing and sending-out pulley with which the first drawing and sending-out mechanism is connected, a second drawing and sending-out pulley with which the second drawing and sending-out mechanism is connected, and a drawing and sending-out belt which is stretched over the first drawing and sending-out pulley and the second drawing and sending-out pulley. When the drawing and sending-out motor is rotated, the drawing and sending-out belt is turned and thereby the first drawing and sending-out mechanism and the second drawing and sending-out mechanism perform the drawing operation or the sending-out operation of the card. 
         [0016]    In at least an embodiment of the present invention, it is preferable that the drawing and sending-out drive mechanism includes a first gear which is coaxially disposed with the first drawing and sending-out pulley and is rotated together with the first drawing and sending-out pulley, a first gear train which is disposed between the first gear and the first drawing and sending-out mechanism and is engaged with the first gear in a transmission path of power from the drawing and sending-out motor to the first drawing and sending-out mechanism, a second gear which is coaxially disposed with the second drawing and sending-out pulley and is rotated together with the second drawing and sending-out pulley, and a second gear train which is disposed between the second gear and the second drawing and sending-out mechanism and is engaged with the second gear in a transmission path of power from the drawing and sending-out motor to the second drawing and sending-out mechanism. The turning mechanism includes one turning motor which is a drive source, a first turning pulley which is fixed to a turnable shaft fixed to the first card holding part, a second turning pulley which is fixed to a turnable shaft fixed to the second card holding part, and a turning belt which is stretched over the first turning pulley and the second turning pulley. When the turning motor is rotated, the turning belt is turned and thereby the first card holding part and the second card holding part are turned together. The first drawing and sending-out pulley and the first turning pulley are coaxially disposed with each other, and the second drawing and sending-out pulley and the second turning pulley are coaxially disposed with each other. When one of the moving direction of the carriage is referred to as a first direction, the first drawing and sending-out pulley, the second drawing and sending-out pulley, the drawing and sending-out belt, the first gear, the first gear train, the second gear, the second gear train, the first turning pulley, the second turning pulley and the turning belt are disposed on the first direction side with respect to the first card holding part and the second card holding part in the moving direction of the carriage. Gears structuring the first gear train are rotatably held by the first card holding part, gears structuring the second gear train are rotatably held by the second card holding part and, when viewed in the moving direction of the carriage, the first card holding part and the second card holding part are point-symmetrically disposed and the first gear train and the second gear train are point-symmetrically disposed with respect to a midpoint of an imaginary line obtained by connecting a turning center of the first card holding part with a turning center of the second card holding part. 
         [0017]    According to this structure, the first drawing and sending-out pulley, the second drawing and sending-out pulley, the drawing and sending-out belt, the first gear, the first gear train, the second gear, the second gear train, the first turning pulley, the second turning pulley and the turning belt are disposed on the first direction side with respect to the first card holding part and the second card holding part in the moving direction of the carriage. Therefore, for example, in comparison with a case that the first drawing and sending-out pulley, the second drawing and sending-out pulley, the drawing and sending-out belt, the first gear, the first gear train, the second gear and the second gear train are disposed on the first direction side with respect to the first card holding part and the second card holding part in the moving direction of carriage, and that the first turning pulley, the second turning pulley and the turning belt are disposed on an opposite side in the first direction with respect to the first card holding part and the second card holding part in the moving direction of carriage, maintenance of the card conveying mechanism can be performed easily. 
         [0018]    Further, according to this structure, when viewed in the moving direction of the carriage, the first card holding part and the second card holding part are point-symmetrically disposed and the first gear train and the second gear train are point-symmetrically disposed with respect to the midpoint of an imaginary line obtained by connecting the turning center of the first turning pulley with the turning center of the second turning pulley. Therefore, even when the first drawing and sending-out pulley, the second drawing and sending-out pulley, the drawing and sending-out belt, the first gear, the first gear train, the second gear, the second gear train, the first turning pulley, the second turning pulley and the turning belt are disposed on the first direction side with respect to the first card holding part and the second card holding part in the moving direction of the carriage and, even when the first card holding part to which the first gear train is attached and the second card holding part to which the second gear train is attached are formed in the same shape as each other, an interference of the first gear train and the second gear train with the turning belt can be prevented when the first card holding part and the second card holding part are turned. 
         [0019]    In at least an embodiment of the present invention, it is preferable that the card conveying mechanism includes a guide shaft which guides the carriage in the moving direction of the carriage and a support frame which supports both end sides of the guide shaft. The drawing and sending-out drive mechanism includes a drawing and sending-out motor which is fixed to the support frame, a drawing and sending-out power transmission shaft formed in a polygonal-column shape whose both end sides in the moving direction of the carriage are rotatably supported by the support frame, a first drawing and sending-out power transmission mechanism structured to transmit power of the drawing and sending-out motor to the drawing and sending-out power transmission shaft to rotate the drawing and sending-out power transmission shaft, and a second drawing and sending-out power transmission mechanism structured to transmit power transmitted to the drawing and sending-out power transmission shaft to the drawing and sending-out mechanism. The turning mechanism includes a turning motor which is fixed to the support frame, a turning power transmission shaft formed in a polygonal-column shape whose both end sides in the moving direction of the carriage are rotatably supported by the support frame, a first turning power transmission mechanism structured to transmit power of the turning motor to the turning power transmission shaft to rotate the turning power transmission shaft, and a second turning power transmission mechanism structured to transmit power transmitted to the turning power transmission shaft to the card holding part. 
         [0020]    According to this structure, the drawing and sending-out motor and the turning motor are fixed to the support frame and the drawing and sending-out motor and the turning motor are not mounted on the carriage. Therefore, cables for supplying electric power to the drawing and sending-out motor and the turning motor and controlling the drawing and sending-out motor and the turning motor are not required to be led out from the carriage. Accordingly, leading-around processing of a cable connected with the drawing and sending-out motor and leading-around processing of a cable connected with the turning motor can be performed easily. 
         [0021]    In at least an embodiment of the present invention, it is preferable that the card conveying mechanism includes, as the guide shaft, a first guide shaft which is supported in an upper end side portion of the support frame and a second guide shaft supported in a lower end side portion of the support frame. When a direction perpendicular to the moving direction of the carriage and an upper and lower direction is referred to as a second direction, the first guide shaft is supported in a portion on one side in the second direction of the support frame, one of the drawing and sending-out power transmission shaft and the turning power transmission shaft is rotatably supported in a lower end side portion of the support frame, and the other of the drawing and sending-out power transmission shaft and the turning power transmission shaft is rotatably supported in a portion of the support frame on an upper end side and one side in the second direction. According to this structure, the other of the drawing and sending-out power transmission shaft and the turning power transmission shaft and the first guide shaft which are supported on the upper end side of the support frame are disposed on the one side in the second direction. Therefore, for example, even in a case that the card conveying mechanism is mounted on a card issuing device and card processing parts for processing a card are disposed around the card conveying mechanism, when performing maintenance of the card conveying mechanism and the card processing parts, an operator can easily put his/her hand in toward a lower end side of the card conveying mechanism from an upper side of the card conveying mechanism. Accordingly, maintenance of the card conveying mechanism and the card processing parts can be performed easily. 
         [0022]    The card conveying mechanism in at least an embodiment of the present invention may be used in a card issuing device including a card accommodation part in which cards before issue are accommodated and a card taking-out part for taking out the card to be issued. According to the card issuing device, even when a card can be conveyed in a horizontal direction and a card can be set in parallel to the horizontal direction or inclined with respect to the horizontal direction, an installation area of the card conveying mechanism can be reduced and thus an installation area of the card issuing device can be reduced. Further, in the card issuing device, the card holding part can be turned with respect to the carriage while linearly moving the carriage in the horizontal direction and thus time required to perform processing of issue of a card can be shortened. 
         [0023]    As describe above, in at least an embodiment of the present invention, even when a card can be conveyed in a horizontal direction and a card can be set in parallel to the horizontal direction or inclined with respect to the horizontal direction, an installation area of a host apparatus such as a card issuing device on which the card conveying mechanism is mounted can be reduced.

       [0034]    At least an embodiment of the present invention will be described below with reference to the accompanying drawings. 
       (Entire Structure of Card Issuing Device) 
       [0035]      FIG. 1  is a perspective view showing a card issuing device  1  in accordance with an embodiment of the present invention.  FIG. 2  is a perspective view showing the card issuing device  1  shown in  FIG. 1  which is viewed from another angle.  FIGS. 3(A) and 3(B)  are explanatory views showing a card  2  which is used in the card issuing device  1  shown in  FIG. 1 . 
         [0036]    A card issuing device  1  in this embodiment includes two card readers  3  and  4  structured to perform reproduction of data recorded in a card  2  (see  FIGS. 3(A) and 3(B) ) and recording of data to the card  2 , a printer  5  structured to print on a card  2 , a labeling machine (labeler)  6  structured to stick a label (seal) on a card  2 , five card accommodation parts  7  in which cards  2  before issue are accommodated, a card taking-out part  8  for taking out a card  2  to be issued, a card collection part  9  to which a card  2  having become unnecessary is collected, and a card conveying mechanism  10  structured to convey a card  2  between these structures. 
         [0037]    A card  2  is a substantially rectangular-shaped card made of vinyl chloride whose thickness is about 0.7-0.8 mm. A rear face  2   a  of the card  2  is formed with a magnetic stripe  2   b  in which magnetic data are recorded. A front face  2   c  of the card  2  is formed with a magnetic stripe  2   d  in which magnetic data are recorded. The magnetic stripes  2   b  and  2   d  are magnetic stripes specified by JIS standard “JISX6302-2”. Further, the front face  2   c  of the card  2  is formed with a magnetic stripe  2   e  in which magnetic data are recorded. The magnetic stripe  2   e  is formed in a longitudinal direction of the card  2  and, in a short-side direction of the card  2 , the magnetic stripe  2   e  is separately formed from the magnetic stripe  2   d  with a predetermined space therebetween. In other words, in this embodiment, the front face  2   c  of the card  2  is formed with two magnetic stripes  2   d  and  2   e,  and the card  2  in this embodiment is a so-called double stripe card. 
         [0038]    The rear face  2   a  of the card  2  may be formed with two magnetic stripes. In other words, the card  2  may be a double stripe card whose rear face  2   a  is formed with two magnetic stripes. Alternatively, the card  2  may be formed so that one magnetic stripe is formed on each of the rear face  2   a  and the front face  2   c.  Further, an IC chip may be incorporated in the card  2 . In this case, a terminal part with which the IC chip is electrically connected is formed on the front face  2   c  of the card  2 , or an antenna is incorporated in the card  2 . Further, the card  2  may be a PET (polyethylene terephthalate) card whose thickness is about 0.18-0.36 mm, or may be a paper card having a predetermined thickness. 
         [0039]    In the following descriptions, three directions perpendicular to each other are referred to as an “X” direction, a “Y” direction and a “Z” direction. In this embodiment, the “Z” direction is coincided with the vertical direction and thus the “Z” direction is an upper and lower direction. Further, the “X” direction is referred to as a right and left direction, the “Y” direction is referred to as a front and rear direction, and the “X1” direction side is a “right” side, the “X2” direction side is a “left” side, the “Y1” direction side is a “front” side, the “Y2” direction side is a “rear” (back) side, the “Z1” direction side is an “upper” side, and the “Z2” direction side is a “lower” side. 
         [0040]    Card readers  3  and  4  are disposed so as to be adjacent to each other in the right and left direction. In this embodiment, the card reader  3  is disposed on a left side and the card reader  4  is disposed on a right side. Further, the card readers  3  and  4  are disposed on a front end side of the card issuing device  1 . The card reader  3  and the card reader  4  are similarly structured to each other. In other words, the card reader  3  and the card reader  4  are structured so that the same structural components are similarly disposed. The card reader  3  and the card reader  4  structured similarly are disposed so that their postures in the front and rear direction are reversed to each other. In other words, when viewed in the upper and lower direction, the card reader  3  and the card reader  4  are point-symmetrically disposed with respect to the midpoint of an imaginary line obtained by connecting the center of the card reader  3  and the center of the card reader  4 . Further, a card conveying passage is formed in each of the insides of the card readers  3  and  4 , the card readers  3  and  4  include conveying mechanisms for a card  2 , and the card readers  3  and  4  are disposed so that a card  2  is conveyed in the front and rear direction. In the card readers  3  and  4 , a card  2  is conveyed in a state that a longitudinal direction of the card  2  and the front and rear direction are coincided with each other. 
         [0041]    The card readers  3  and  4  include magnetic heads (not shown) configured to perform reading of magnetic data recorded on a card  2  and/or recording of magnetic data to a card  2 . In this embodiment, reading of magnetic data recorded in the magnetic stripes  2   b  and  2   d  and/or recording of magnetic data to the magnetic stripes  2   b  and  2   d  are performed by the magnetic heads of the card reader  3 , and the reading of magnetic data recorded in the magnetic stripe  2   e  and/or recording of magnetic data to the magnetic stripe  2   e  are performed by the magnetic head of the card reader  4 . 
         [0042]    The card reader  3  includes two magnetic heads, i.e., a magnetic head configured to perform reading and/or recording of magnetic data to the magnetic stripe  2   b  formed on the rear face  2   a  of the card  2  and a magnetic head configured to perform reading and/or recording of magnetic data to the magnetic stripe  2   d  formed on the front face  2   c  of the card  2 . The card reader  3  and the card reader  4  are similarly structured to each other and thus the card reader  4  also includes two magnetic heads. However, it is sufficient that the card reader  4  includes a magnetic head configured to perform reading and/or recording of magnetic data to the magnetic stripe  2   e  formed on the front face  2   c  of the card  2  and thus the card reader  4  may include only one magnetic head. Further, in a case that an IC chip is incorporated in the card  2 , it is sufficient that only one of the card reader  3  and the card reader  4  includes IC contact points and/or an antenna for performing data communication with the card  2 . For example, it is sufficient that only the card reader  3  includes IC contact points and/or an antenna. As described above, the structure of the card reader  3  and the structure of the card reader  4  may be different from each other. 
         [0043]    The printer  5  and the labeler  6  are disposed so as to be adjacent to each other in the right and left direction. In this embodiment, the printer  5  is disposed on the right side and the labeler  6  is disposed on the left side. Further, the card issuing device  1  in this embodiment is provided with a so-called two-story structure, and the printer  5  and the labeler  6  are disposed on the front end side of the card issuing device  1  and on the upper side of the card readers  3  and  4 . In other words, the card readers  3  and  4  and the printer  5  and the labeler  6  are overlapped with each other in the upper and lower direction. Further, the labeler  6  is disposed on the upper side of the card reader  3  and the printer  5  is disposed on the upper side of the card reader  4 . 
         [0044]    An inside of the printer  5  is formed with a card conveying passage and the printer  5  includes a conveying mechanism for a card  2 . The printer  5  is disposed so that a card  2  is conveyed in the front and rear direction. Further, an inside of the labeler  6  is formed with a card conveying passage and the labeler  6  includes a conveying mechanism for a card  2 . The labeler  6  is disposed so that a card  2  is conveyed in the front and rear direction.

The belt  78  in this embodiment is a turning belt. 
         [0075]    As described above, the pulley  54  is rotatably held by the turnable shaft  33  and the pulley  73  and the pulley  54  are coaxially disposed with each other. Further, the pulleys  73  and the belt  78  are disposed on the right side with respect to the card holding parts  15  and  16 . Further, the pulleys  73  and the belt  78  are disposed on the left side with respect to the pulleys  54 , the gears  55  and the gear trains  56 . In this embodiment, a second turning power transmission mechanism is structured by two pulleys  73  and the pulley  77  and the belt  78  for transmitting power transmitted to the power transmission shaft  72  which is a turning power transmission shaft to the card holding parts  15  and  16 . The turning mechanism  24  includes a tension pulley  79  for applying tension to the belt  78  (see  FIG. 6 ). The tension pulley  79  is adjacently disposed to the pulley  77  on the front side. Further, the tension pulley  79  is rotatably held by a fixed shaft which is fixed to the side plate  28  of the carriage  17 . 
         [0076]    In the card conveying mechanism  10 , when the motor  71  is rotated, the power transmission shaft  72 , the pulleys  73  and  77 , the belt  78  and the like are turned and the turnable shaft  33  is turned and thus, the card holding part  15  and the card holding part  16  are turned together in the same direction around the turnable shafts  33 . In other words, the card holding parts  15  and  16  are turned with the right and left direction as an axial direction of turning. Each of the card holding parts  15  and  16  in this embodiment is turnable by 180° with the turnable shaft  33  as a center from a state that the card conveying passage  32  is parallel to the horizontal direction (state shown in  FIG. 6  or state shown in  FIG. 8(B) ) to a vertically reversed state of the card conveying passage  32  (state shown in  FIG. 8(B)  or state in  FIG. 6 ). Further, in this embodiment, when the card holding parts  15  and  16  are turned to middle positions of turning ranges of the card holding parts  15  and  16  (in other words, when the card holding parts  15  and  16  are turned by 90° from the state shown in  FIG. 6  or the state shown in  FIG. 8(B) ), an axial distance between the turnable shaft  33  fixed to the card holding part  15  and the turnable shaft  33  fixed to the card holding part  16  is set so that a card  2  is capable of being directly transferred between the card holding part  15  and the card holding part  16  in the upper and lower direction. 
         [0077]    In this embodiment, in a state that the turnable shaft  33 , the pulleys  54  and  73 , the gear  55  and the gear train  56  are attached, the card holding part  15  and the card holding part  16  are formed in the same shape as each other. Further, when viewed in the right and left direction, the card holding part  15  and the second card holding part  16  are point-symmetrically disposed and the gear train  56  rotatably held by the card holding part  15  and the gear train  56  rotatably held by the card holding part  16  are point-symmetrically disposed with respect to the midpoint “C” of an imaginary line “L” (see  FIG. 6 ) obtained by connecting the turning center of the card holding part  15  (in other words, an axial center of the turnable shaft  33  fixed to the card holding part  15 ) with the turning center of the card holding part  16  (in other words, an axial center of the turnable shaft  33  fixed to the card holding part  16 ). 
         [0078]    In this embodiment, in a state that the card conveying passage  32  is set to be parallel to the horizontal direction, in the upper and lower direction, the heights of the card conveying passages of the card readers  3  and  4  and the height of the card conveying passage  32  of the card holding part  16  are coincided with each other, and the height of the card conveying passage of the printer  5  and the height of the card conveying passage of the labeler  6  and the height of the card conveying passage  32  of the card holding part  15  are coincided with each other. Further, in a state that the card conveying passage  32  is set to be parallel to the horizontal direction, in the upper and lower direction, the height of the card conveying passage  32  of the card holding part  15  and the heights of the sending-out apertures for a card  2  of two card accommodation parts  7  disposed on an upper side are coincided with each other. Further, the height of the card conveying passage  32  of the card holding part  16  and the heights of the sending-out apertures for a card  2  of three card accommodation parts  7  disposed on a lower side are coincided with each other. In addition, in a state that the card conveying passage  32  is set to be parallel to the horizontal direction, the card conveying passage  32  of the card holding part  15  is disposed on a slightly upper side with respect to a bottom face of the card taking-out part  8 . 
       (Card Issuing Operation of Card Issuing Device) 
       [0079]    A card issuing device  1  structured as described above issues a card  2 , for example, by being operated as described below. An issuing operation of a card  2  as described below is an example of a card issuing operation by the card issuing device  1  and a card issuing operation by the card issuing device  1  is not limited to the operation described below. 
         [0080]    In order to issue a card  2 , first, either of five card accommodation parts  7  sends out a card  2  toward a front side. In this case, the card conveying passages  32  of the card holding parts  15  and  16  are set to be parallel to the horizontal direction, and the drawing and sending-out mechanism  22  of the card holding part  15  or the drawing and sending-out mechanism  22  of the card holding part  16  draws a card  2  sent out from the card accommodation part  7  into the inside of the card holding part  15  or the inside of the card holding part  16  and holds it. Further, in a case that a card  2  has been drawn into the inside of the card holding part  15 , the card holding parts  15  and  16  are turned by 90° and the drawing and sending-out mechanisms  22  transfers the card  2  from the card holding part  15  to the card holding part  16 . When transfer of the card  2  from the card holding part  15  to the card holding part  16  is finished, the card holding parts  15  and  16  are turned so that the card conveying passages  32  are parallel to the horizontal direction. 
         [0081]    After that, the drawing and sending-out mechanism  22  of the card holding part  16  sends out the card  2  to a front side toward the card reader  3  and the card reader  3  draws the card  2 . When the card  2  has been drawn into the inside of the card holding part  15  or the inside of the card holding part  16 , in a case that the position in the right and left direction of the card holding part  16  and the position in the right and left direction of the card reader  3  are different from each other, the carriage  17  is moved in the right and left direction so that the position in the right and left direction of the card holding part  16  and the position in the right and left direction of the card reader  3  are coincided with each other before the drawing and sending-out mechanism  22  of the card holding part  16  sends out the card  2  toward the card reader  3 . In this case, in a case that the card  2  is transferred from the card holding part  15  to the card holding part  16 , the carriage  17  may be moved in the right and left direction while performing the transfer operation. 
         [0082]    After that, the card reader  3  reads magnetic data recorded in a magnetic stripe  2   b  and a magnetic stripe  2   d  of the card  2  and records magnetic data in the magnetic stripes  2   b  and  2   d.  Further, in a case that an IC chip is incorporated in the card  2 , the card reader  3  records data in the IC chip of the card  2 . When recording of magnetic data to the magnetic stripes  2   b  and  2   d  and recording of data to the IC chip are finished, the card reader  3  sends out the card  2  to a rear side. The drawing and sending-out mechanism  22  of the card holding part  16  draws the card  2  sent out from the card reader  3  into the inside of the card holding part  16  and holds it. After that, the carriage  17  is moved to the right direction so that the position of the card holding part  16  and the position of the card reader  4  are coincided with each other in the right and left direction. 
         [0083]    After that, the drawing and sending-out mechanism  22  of the card holding part  16  sends out the card  2  to a front side toward the card reader  4 , and the card reader  4  draws the card  2 . The card reader  4  records magnetic data in a magnetic stripe  2   e  of the card  2  and, after that, the card  2  is sent out to a rear side. Further, the drawing and sending-out mechanism  22  of the card holding part  16  draws the card  2  sent out from the card reader  4  into the inside of the card holding part  16  and holds it. 
         [0084]    After that, the card holding parts  15  and  16  are turned by 90° and the drawing and sending-out mechanisms  22  transfers the card  2  from the card holding part  16  to the card holding part  15 . When transfer of the card  2  from the card holding part  16  to the card holding part  15  is finished, the card holding parts  15  and  16  are turned so that the card conveying passages  32  are parallel to the horizontal direction. In this case, the position of the card holding part  15  and the position of the printer  5  are coincided with each other in the right and left direction. 
         [0085]    After that, the drawing and sending-out mechanism  22  of the card holding part  15  sends out the card  2  to a front side toward the printer  5 , and the printer  5  draws the card  2 . After the printer  5  prints on the card  2 , the card  2  is sent out to a rear side. Further, the drawing and sending-out mechanism  22  of the card holding part  15  draws the card  2  sent out from the printer  5  into the inside of the card holding part  15  and holds it. After that, the carriage  17  is moved to the left direction so that the position of the card holding part  15  and the position of the labeler  6  are coincided with each other in the right and left direction. 
         [0086]    In a case that printing is performed on both faces of the card  2 , the card holding parts  15  and  16  are turned by 180° in a state that the card  2  sent out from the printer  5  is held in the inside of the card holding part  15 , and front and back faces of the card  2  are reversed. After that, the drawing and sending-out mechanism  22  of the card holding part  15  sends out the card  2  toward the printer  5  and the printer  5  draws the card  2  and printing is performed on the card  2  and the card  2  is sent out to a rear side. 
         [0087]    When the carriage  17  is moved so that the position of the card holding part  15  and the position of the labeler  6  are coincided with each other in the right and left direction, the drawing and sending-out mechanism  22  of the card holding part  15  sends out the card  2  to a front side toward the labeler  6 , and the labeler  6  draws the card  2 . After the labeler  6  has stuck a label on the card  2 , the labeler  6  sends out the card  2  to a rear side. The drawing and sending-out mechanism  22  of the card holding part  15  draws the card  2  sent out from the labeler  6  into the inside of the card holding part  15  and holds it. 
         [0088]    After that, the carriage  17  is moved to the left direction so that the position of the card holding part  15  and the position of the card taking-out part  8  are coincided with each other in the right and left direction. After that, the drawing and sending-out mechanism  22  of the card holding part  15  sends out the card  2  to a rear side toward the card taking-out part  8 , and the card  2  sent out is entered in the card taking-out part  8  formed in a box shape. In this case, when some error such as a recording error of magnetic data is generated during performing issue processing of the card  2 , the card holding parts  15  and  16  are turned so that the rear end side of the card holding part  15  is inclined downward in a state that the position of the card holding part  15  and the position of the card taking-out part  8  are coincided with each other in the right and left direction. After that, the drawing and sending-out mechanism  22  of the card holding part  15  sends out the card  2  to an obliquely rear lower side toward the card collection part  9 , and the card  2  sent out is entered in the card collection part  9  formed in a box shape. 
         [0089]    As described above, in this embodiment, the drawing and sending-out mechanisms  22  of the card holding parts  15  and  16  draw a card  2  toward the insides of the card holding parts  15  and  16  to the front direction or to the rear direction. In other words, in this embodiment, the front and rear direction (“Y” direction) is a drawing direction of a card  2  to the card holding parts  15  and  16 . Further, the drawing and sending-out mechanism  22  of the card holding part  16  sends out a card  2  from the inside of the card holding part  16  to a front direction, and the drawing and sending-out mechanism  22  of the card holding part  15  sends out a card  2  from the inside of the card holding part  15  to a front direction or a rear direction except a case sending out a card  2  to the card collection part  9 . 
         [0000]    (Principal Effects in this Embodiment) 
         [0090]    As described above, the card conveying mechanism  10  in this embodiment includes the carriage drive mechanism  18  structured to linearly move the carriage  17  on which the card holding parts  15  and  16  are mounted in the right and left direction. Further, the card conveying mechanism  10  includes the turning mechanism  24  structured to turn the card holding parts  15  and  16  with respect to the carriage  17  with the right and left direction as an axial direction of turning, and the card holding parts  15  and  16  are capable of turning by 180° with the turnable shafts  33  as turning centers. Therefore, in this embodiment, a card  2  held by the card holding parts  15  and  16  is capable of being conveyed in the right and left direction, and a card  2  held by the card holding parts  15  and  16  is capable of setting to be parallel to the horizontal direction and being inclined with respect to the horizontal direction. Further, in this embodiment, the card holding parts  15  and  16  mounted on the carriage  17  are linearly moved in the right and left direction and are turned with the right and left direction as an axial direction of turning. Therefore, in comparison with a case that a card holding part linearly moved in the right and left direction and a card holding part turned with the right and left direction as an axial direction of turning are separately provided from each other like the card issuing device described in Patent Literature 1, the size of the card conveying mechanism  10  can be made small and an installation area of the card conveying mechanism  10  can be reduced. Accordingly, in this embodiment, even when a card  2  can be conveyed in the right and left direction and a card  2  can be set in parallel to the horizontal direction or inclined with respect to the horizontal direction, an installation area of the card issuing device  1  on which the card conveying mechanism  10  is mounted can be reduced. Further, in this embodiment, the card holding parts  15  and  16  can be turned with respect to the carriage  17  while the carriage  17  is linearly moved in the right and left direction and thus a time for performing issue processing of a card  2  can be shortened. 
         [0091]    In this embodiment, the card holding part  15  and the card holding part  16  are disposed so as to overlap with each other in the upper and lower direction and, when the card holding parts  15  and  16  are turned to the state shown in  FIG. 8(A) , a card  2  can be transferred between the card holding part  15  and the card holding part  16  in the upper and lower direction. Therefore, according to this embodiment, a card  2  can be conveyed in the card conveying mechanism  10  in the upper and lower direction. Accordingly, in this embodiment, even when the card readers  3  and  4  and the printer  5  and the labeler  6  are disposed so as to overlap in the upper and lower direction and, even when two card accommodation parts  7 , the card taking-out part  8  and the card collection part  9  and three card accommodation parts  7  are disposed so as to overlap in the upper and lower direction, a card  2  sent out from the card accommodation part  7  can be conveyed between the card readers  3  and  4 , the printer  5  and the labeler  6  by the card conveying mechanism  10  and can be sent to the insides of the card taking-out part  8  and the card collection part  9 . 
         [0092]    In this embodiment, two card holding parts  15  and  16  are mounted on the common carriage  17 . Therefore, according to this embodiment, in comparison with a case that carriages on which two card holding parts  15  and  16  are respectively mounted are individually provided, the structure of the card conveying mechanism  10  can be simplified. 
         [0093]    In this embodiment, when one motor  71  is rotated, two card holding parts  15  and  16  are turned together in the same direction. Therefore, according to this embodiment, in comparison with a case that a motor for turning the card holding part  15  and a motor for turning the card holding part  16  are individually provided, the structure of the turning mechanism  24  can be simplified. Further, according to this embodiment, alignment of the card holding part  15  with the card holding part  16  can be performed by controlling one motor  71  when a card  2  is transferred between the card holding part  15  and the card holding part  16  in the upper and lower direction. Therefore, the card conveying mechanism  10  is easily controlled when a card  2  is conveyed in the upper and lower direction. 
         [0094]    In this embodiment, when one motor  52  is rotated, the drawing and sending-out mechanism  22  of the card holding part  15  and the drawing and sending-out mechanism  22  of the card holding part  16  perform an drawing operation of a card  2  or an sending-out operation of a card  2 . Therefore, according to this embodiment, in comparison with a case that a motor for driving the drawing and sending-out mechanism  22  of the card holding part  15  and a motor for driving the drawing and sending-out mechanism  22  of the card holding part  16  are individually provided, a structure of the drawing and sending-out drive mechanism  23  can be simplified. Further, in this embodiment, a sending-out operation of a card  2  by the drawing and sending-out mechanism  22  of the card holding part  15  can be easily synchronized with a drawing operation of the card  2  by the drawing and sending-out mechanism  22  of the card holding part  16 . Further, a sending-out operation of a card  2  by the drawing and sending-out mechanism  22  of the card holding part  16  can be easily synchronized with a drawing operation of the card  2  by the drawing and sending-out mechanism  22  of the card holding part  15 . Therefore, when performing transfer of a card  2  between the card holding part  15  and the card holding part  16  in the upper and lower direction, a card  2  can be easily and smoothly transferred between the card holding part  15  and the card holding part  16 . 
         [0095]    In this embodiment, the pulleys  54 , the belt  62  and the gears  55 ,  63  and  64  structuring the drawing and sending-out drive mechanism  23  and the pulleys  73  and the belt  78  structuring the turning mechanism  24  are disposed on the right side with respect to the card holding parts  15  and  16 . Therefore, according to this embodiment, for example, in comparison with a case that the pulleys  54 , the belt  62  and the gears  55 ,  63  and  64  are disposed on the right side with respect to the card holding parts  15  and  16 , and that the pulleys  73  and the belt  78  are disposed on the left side with respect to the card holding parts  15  and  16 , maintenance of the card conveying mechanism  10  is easily performed. 
         [0096]    In this embodiment, when viewed in the right and left direction, the card holding part  15  and the second card holding part  16  are point-symmetrically disposed and the gear train  56  rotatably held by the card holding part  15  and the gear train  56  rotatably held by the card holding part  16  are point-symmetrically disposed with respect to the midpoint “C” of an imaginary line “L” obtained by connecting the turning center of the card holding part  15  with the turning center of the card holding part  16 . Therefore, according to this embodiment, even when the pulleys  54 , the belt  62  and the gears  55 ,  63  and  64  structuring the drawing and sending-out drive mechanism  23  and the pulleys  73  and the belt  78  structuring the turning mechanism  24  are disposed on the right side with respect to the card holding parts  15  and  16  and, even when the card holding part  15  and the card holding part  16  are formed in the same shape as each other in a state that the gear train  56  is attached, an interference of the gear train  56  with the belt  78  can be prevented when the card holding parts  15  and  16  are turned. 
         [0097]    In this embodiment, power of the motor  52  is transmitted to the pulley  61  through the power transmission shaft  53  rotatably supported by the support frame  21  and the motor  52  is fixed to the support frame  21 . Further, power of the motor  71  is transmitted to the pulley  77  through the power transmission shaft  72  rotatably supported by the support frame  21  and the motor  71  is fixed to the support frame  21 . In other words, in this embodiment, the motors  52  and  71  are not mounted on the carriage  17 . Therefore, according to this embodiment, cables for supplying electric power to the motors  52  and  71  and controlling the motors  52  and  71  are not required to be led out from the carriage  17 . Accordingly, in this embodiment, leading-around processing of cables connected with the motors  52  and  71  can be performed easily. 
         [0098]    In this embodiment, the guide shaft  19  is supported in portions on an upper end side and a rear end side of two side plates  26 , and the power transmission shaft  72  is adjacently disposed to an obliquely front upper side of the guide shaft  19  and is turnably supported by the portions on the upper end side and the rear end side of two side plates  26 . Further, the guide shaft  20  is supported in a lower end side portion of two side plates  26  and the power transmission shaft  53  is turnably supported by a lower end side portion of the two side plates  26 . Therefore, according to this embodiment, even in a case that the card readers  3  and  4 , the printer  5 , the labeler  6  and the card accommodation parts  7  are disposed around the card conveying mechanism  10 , when performing maintenance of the card conveying mechanism  10 , the card readers  3  and  4 , the printer  5 , the labeler  6  and the card accommodation parts  7 , an operator can easily put his/her hand in toward a lower end side of the card conveying mechanism  10  from an upper side of the card conveying mechanism  10 . Accordingly, in this embodiment, maintenance of the card conveying mechanism  10 , the card readers  3  and  4 , the printer  5 , the labeler  6  and the card accommodation parts  7  can be performed easily. 
         [0099]    In this embodiment, the card reader  3  and the card reader  4  designed to perform recording and/or reading of magnetic data to and/or from the magnetic stripes  2   b  and  2   d  specified in JIS standard “JISX6302-2” are disposed so that their postures in the front and rear direction are reversed each other. Further, reading of magnetic data recorded in the magnetic stripes  2   b  and  2   d  and/or recording of magnetic data to the magnetic stripes  2   b  and  2   d  are performed by magnetic heads of the card reader  3 , and reading of magnetic data recorded in the magnetic stripe  2   e  and/or recording of magnetic data to the magnetic stripe  2   e  are performed by a magnetic head of the card reader  4 . Therefore, according to this embodiment, even when magnetic data can be recorded and/or read to and/or from a so-called double stripe type card  2 , a dedicated card reader is not required to prepare for performing recording and/or reading of magnetic data to the magnetic stripe  2   e.  Further, in this embodiment, recording and/or reading of magnetic data can be performed to and/or from a double stripe type card  2  by selecting a conveyance destination of the card  2  by the card conveying mechanism  10 . 
       (Other Embodiments) 
       [0100]    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. 
         [0101]    In the embodiment described above, the card issuing device  1  includes the card reader  4  and the labeler  6  but the card issuing device  1  may include no card reader  4  and no labeler  6 . In this case, the card reader  4  and the labeler  6  may be detached as they are from the card issuing device  1  in the embodiment described above, but the card reader  3  and the printer  5  may be disposed so as to be adjacent to each other in the right and left direction. Alternatively, in this case, the printer  5  may be disposed on an upper side of the card reader  3  so that the card reader  3  and the printer  5  are overlapped with each other in the upper and lower direction. 
         [0102]    In a case that the card reader  3  and the printer  5  are disposed so as to be adjacent to each other in the right and left direction, for example, the printer  5  is disposed at the position where the card reader  4  is disposed in the embodiment described above and two card accommodation parts  7  and the card taking-out part  8  and the card collection part  9  overlapped with each other in the upper and lower direction are disposed so as to be adjacent to each other in the right and left direction at the position where three card accommodation parts  7  are disposed so as to be adjacent to each other in the embodiment described above. In other words, the card issuing device  1  is structured as a so-called one story structure. In this case, as shown in  FIG. 9 , one card holding part  16  is mounted on the carriage  17  and the card conveying mechanism  10  conveys a card  2  sent out from the card accommodation part  7  between the card reader  3  and the printer  5  and, after processing in the card reader  3  and the printer  5  is finished, the card  2  is sent to the card taking-out part  8  or the card collection part  9 . Further, when performing printing on both faces of a card  2  by the printer  5 , the card conveying mechanism  10  turns the card holding part  16  so that the front and back faces of the card  2  are reversed. In a case that the card reader  3  and the printer  5  are adjacently disposed to each other in the right and left direction, a height of the card issuing device  1  can be set low. In  FIG. 9 , the same reference signs are used in the same structure as the embodiment described above. 
         [0103]    In a case that the printer  5  is disposed on an upper side of the card reader  3 , the card issuing device  1  includes, for example, three card accommodation parts  7 , and two of the three card accommodation parts  7  are disposed so as to be adjacent to each other in the right and left direction. Further, remaining one card accommodation part  7  and the card taking-out part  8  and the card collection part  9  overlapped in the upper and lower direction are disposed on an upper side of the two card accommodation parts  7 . In this case, a width of the card issuing device  1  in the right and left direction can be narrowed. 
         [0104]    In the embodiment described above, the card issuing device  1  is structured as a two-story structure, but the card issuing device  1  may be structured as an “N”-story structure (“N” is an integer not less than 3) such as a three-story structure. In this case, “N” pieces of the card holding part which are disposed so as to be overlapped in the upper and lower direction are mounted on the carriage  17 . 
         [0105]    In the embodiment described above, in the upper and lower direction, an axial distance between the turnable shaft  33  fixed to the card holding part  15  and the turnable shaft  33  fixed to the card holding part  16  is set so that a card  2  can be directly transferred between the card holding part  15  and the card holding part  16 . However, the present invention is not limited to this embodiment. For example, an axial distance between the turnable shaft  33  fixed to the card holding part  15  and the turnable shaft  33  fixed to the card holding part  16  may be set longer than a length that a card  2  can be directly transferred between the card holding part  15  and the card holding part  16 . In this case, a drive roller and the like for conveying a card  2  may be disposed between the card holding part  15  and the card holding part  16  in the upper and lower direction so that a card  2  can be transferred between the card holding part  15  and the card holding part  16  in the upper and lower direction. 
         [0106]    In the embodiment described above, the card holding parts  15  and  16  are capable of turning by 180° from a state that the card conveying passage  32  are parallel to the horizontal direction to a state that the card conveying passage  32  is vertically reversed with the turnable shaft  33  as a center. However, the present invention is not limited to this embodiment. For example, the card holding parts  15  and  16  may be turned by 90° from the state that the card conveying passage  32  is parallel to the horizontal direction with the turnable shaft  33  as a center. In this case, although the front and back faces of a card  2  is unable to be vertically reversed but a card  2  can be conveyed in the upper and lower direction. 
         [0107]    In the embodiment described above, power of the motor  52  is transmitted to the power transmission shaft  53  by the pulleys  58  and  59  and the belt  60 . However, power of the motor  52  may be transmitted to the power transmission shaft  53  by a gear train. Further, in the embodiment described above, power transmitted to the power transmission shaft  53  is transmitted to the gear  55  by two pulleys  54 , the pulley  61  and the belt  62 , but power transmitted to the power transmission shaft  53  may be transmitted to the gear  55   b  by a gear train. In addition, in the embodiment described above, power transmitted to the pulley  54  is transmitted to the drawing and sending-out mechanism  22  by the gear  55  and the gear train  56 . However, power transmitted to the pulley  54  may be transmitted to the drawing and sending-out mechanism  22  by a pulley and a belt. Further, the drawing and sending-out mechanism  22  includes the pulley  37  and the belt  38  but may include a gear train instead of the pulley  37  and the belt  38 . 
         [0108]    In the embodiment described above, power of the motor  71  is transmitted to the power transmission shaft  72  by the pulleys  74  and  75  and the belt  76 . However, power of the motor  71  may be transmitted to the power transmission shaft  72  by a gear train. Further, in the embodiment described above, power transmitted to the power transmission shaft  72  is transmitted to the card holding parts  15  and  16  by two pulleys  73 , the pulley  77  and the belt  78 . However, power transmitted to the power transmission shaft  72  may be transmitted to the card holding parts  15  and  16  by a gear train. 
         [0109]    In the embodiment described above, the pulleys  54 , the belt  62  and the gears  55 ,  63  and  64  structuring the drawing and sending-out drive mechanism  23  and the pulleys  73  and the belt  78  structuring the turning mechanism  24  are disposed on the right side with respect to the card holding parts  15  and  16 . However, the present invention is not limited to this embodiment. For example, it may be structured that the pulleys  54 , the belt  62  and the gears  55 ,  63  and  64  are disposed on one of the right side and the left side with respect to the card holding parts  15  and  16  and that the pulleys  73  and the belt  78  are disposed on the other of the right side and the left side with respect to the card holding parts  15  and  16 . In this case, the card holding part  15  and the card holding part  16  may not be disposed point-symmetrically with respect to the midpoint “C” of the imaginary line “L”. Further, in this case, the gear train  56  rotatably held by the card holding part  15  and the gear train  56  rotatably held by the card holding part  16  may not be disposed point-symmetrically with respect to the midpoint “C”. 
         [0110]    In the embodiment described above, two card holding parts  15  and  16  are mounted on the common carriage  17 . However, a carriage on which the card holding part  15  is mounted and a carriage on which the card holding part is mounted may be provided individually. Further, in the embodiment described above, the drawing and sending-out mechanism  22  of the card holding part  15  and the drawing and sending-out mechanism  22  of the card holding part  16  are operated by one motor  52 . However, a motor for operating the drawing and sending-out mechanism  22  of the card holding part  15  and a motor for operating the drawing and sending-out mechanism  22  of the card holding part  16  may be provided individually. Similarly, in the embodiment described above, two card holding parts  15  and  16  are turned by one motor  71 . However, a motor for turning the card holding part  15  and a motor for turning the card holding part  16  may be provided individually. In this case, the card holding part  15  and the card holding part  16  may not be disposed point-symmetrically with respect to the midpoint “C” of the imaginary line “L”. Further, in this case, the gear train  56  rotatably held by the card holding part  15  and the gear train  56  rotatably held by the card holding part  16  may not be disposed point-symmetrically with respect to the midpoint “C”. 
         [0111]    In the embodiment described above, the motor  52  is not mounted on the carriage  17  but the motor  52  may be mounted on the carriage  17 . Similarly, the motor  71  is not mounted on the carriage  17  but the motor  71  may be mounted on the carriage  17 . Further, in the embodiment described above, the card holding part  15  and the card holding part  16  are formed in the same shape as each other, but the shape of the card holding part  15  and the shape of the card holding part  16  may be different from each other. Further, in the embodiment described above, the power transmission shafts  53  and  72  are formed in a hexagonal columnar shape. However, the power transmission shafts  53  and  72  may be formed in a polygonal columnar shape such as a rectangular columnar shape or an octagonal columnar shape other than a hexagonal columnar shape. 
         [0112]    In the embodiment described above, the drawing and sending-out mechanism  22  includes the drive roller  34  and the pad roller  35 . However, the drawing and sending-out mechanism  22  may include a belt for drawing or sending a card  2  in or out instead of the drive roller  34  and the pad roller  35 . Further, in the embodiment described above, the carriage moving mechanism  18  includes the belt  49  and the carriage  17  is moved in the right and left direction by the belt  49 . However, the carriage moving mechanism  18  may move the carriage  17  in the right and left direction by a ball screw or the like. 
         [0113]    In the embodiment described above, the printer  5  and the labeler  6  are disposed on an upper side of the card readers  3  and  4 . However, the present invention is not limited to this embodiment. For example, the card readers  3  and  4  may be disposed on an upper side of the printer  5  and the labeler  6 . Further, in the embodiment described above, the card conveying mechanism  10  is mounted on the card issuing device  1 . However, the card conveying mechanism  10  may be mounted on a host apparatus other than the card issuing device  1 . 
         [0114]    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. 
         [0115]    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.
