Description

  The present invention relates to a card issuing machine and a shutter mechanism, and more particularly to a card issuing machine provided with a shutter mechanism provided in the vicinity of a card discharge port of a card stacker and the shutter mechanism.

  A card issuing machine that sends out cards one by one from a stacked state is arranged opposite to a card stacker in which a plurality of cards are stacked, and a bottom portion of the card stacker, and is at the bottom of the plurality of cards. And a sending means for sending a card to be placed out of the card stacker. At the bottom of the card stacker, a card discharge port is formed for sending out the cards placed at the lowest position one by one (see, for example, Patent Document 1).

  A pair of members are opposed to the card discharge port with a predetermined gap therebetween. The gap is about the thickness of the card, and is dimensioned so that only the bottom card is passed through and the card placed thereon is not passed.

  Since the card stacker is detachably attached to the card issuing machine, when a card is replenished in the card stacker, the card stacker is usually removed from the card issuing machine and the card is replenished at another location. At this time, if the card discharge port at the bottom of the card stacker is left open, the card may jump out of the card discharge port and be lost while the card stacker is being carried after the card is replenished.

Various studies have been made on such problems. For example, in Patent Document 2, a shutter is provided in the vicinity of the card discharge port of the card stacker to prevent the card from jumping out of the card stacker during conveyance, and a key lock mechanism is provided on the card stacker so that the shutter can be opened and closed. A card issuing machine has been proposed.

  As shown in FIGS. 1 and 2, the card stacker 11 is opened when a card discharge port 41 for sending out the card 1 b placed at the bottommost position and when the card stacker 11 is detached (removed) from the hopper 21. And a support plate 14 provided on the card discharge port 41 side and supporting the movement of the shutter 61 (corresponding to a card stacker wall surface on the card discharge port 41 side). ) And restricting means provided on the support plate 14 to prevent the shutter 61 from moving to the open position.

  In the vicinity of the inside of the card discharge port 41, reference plates 44 and 45 are provided so as to face each other with a predetermined gap so that only one card can pass through. The shutter 61 includes the reference plate. 44 and 45 are provided on the outside (on the card discharge port 41 side) so that the card discharge port 41 can be closed. As shown in FIG. 1, the card 1 is stacked on the bottom plate 13 of the card stacker 11, and the weight 2 that slides in the vertical direction by the weight engaging flange 3 is placed on the uppermost card 1a. ing. Further, a cover plate 16 that closes the card slot 12 is provided above the card stacker 11, and a handle 48 and a lock 50 as shown in the drawing are usually provided on the cover plate 16.

  The shutter structure 60 is provided above the card discharge port 41 and can open and close the card discharge port 41 by attaching and detaching the card stacker 11 and the hopper 21. As shown in FIG. , And a horizontal moving member 63 sandwiched between the card stacker 11 and the shutter 61. In other words, the shutter structure 60 includes the shutter 61, the support plate 14 that forms the wall surface on the card discharge port 41 side of the card stacker 11, and the horizontal moving member 63 provided between the shutter 61 and the support plate 14. Arm members (regulating means).

  The horizontal moving member 63 is a member that slides horizontally on the inclined surface 66 (see FIG. 3) of the engaging member 65 by the relative movement of the engaging member 65 in FIG. 1 in the vertical direction. Is a pin-shaped contact member that is provided on the lower end side of the plate-shaped member 91 and contacts the engaging member 65.

  As shown in FIG. 1, the engaging member 65 is provided at a position opposite to the shutter structure 60, and engages the shutter structure 60 from below when the card stacker 11 is attached to the hopper 60 to open the shutter 60. Specifically, as shown in FIG. 3, the member is a member having a substantially triangular shape, which is provided on the hopper wall surface 67 so as to protrude toward the card stacker 11 and includes an inclined surface 66 and a tip portion 68.

  Hereinafter, two embodiments of the shutter structure of the card issuing machine of the present invention will be illustrated and described in detail.

(First embodiment)
FIG. 4 is an explanatory diagram of the shutter structure 60 according to the first embodiment. The wall surface 14 (hereinafter referred to as a support plate 14) on the card discharge port side of the card stacker, the horizontal moving member 63, the shutter 61, It is a disassembled block diagram with the engaging member 65. FIG.

  The shutter structure 60 shown in FIG. 4 is sandwiched between the card stacker 11 and the shutter 60, and the engaging member 65 moves relative to the vertical direction to slide horizontally on the slope 66 of the engaging member 65. A horizontal moving member 63 is provided. The shutter 60 allows the shutter 60 to move upward when the engaging member 65 moves relatively upward and the horizontal moving member 63 moves horizontally by a predetermined dimension. When the engagement member 65 is relatively moved downward and the horizontal moving member 63 returns to the original position, the shutter 60 is not cut into an inverted L-shape or T-shape or the like which makes the upward movement impossible. One or two or more slits 79, 79 are provided.

  As shown in FIG. 4, a pair of horizontal moving members 63 are attached to the support plate 14. The horizontal moving member 63 is a member that slides on the inclined surface 66 of the engaging member 65 as the engaging member 65 moves in the vertical direction and moves horizontally as indicated by the arrow in FIG. It is illustrated as a shape member. The horizontal moving member 63 is provided on the lower end side of the vertically long plate-like member 91 extending upward. The upper end of the plate-like member 91 is attached to the support plate 14 via a shaft member 93 so that the plate-like member 91 can rotate, and a pair of plate-like members is slightly below the shaft member 93. An elastic member (spring 89) is provided to act so as to shrink between 91 and 91. The elastic member (spring 89) urges the horizontal moving member 63 to come into contact with the engaging member 65. Therefore, the elastic member (spring 89) can also be referred to as an “urging member”.

  Furthermore, the support plate 14 on the card discharge port side of the card stacker is provided with a flange-shaped pin for mounting a shutter 61 that moves up and down. In FIG. 4, it engages with a long hole 77 above the shutter. There are provided a pin 75 and two pins 87 respectively engaged with a pair of left and right slots 81 and 81 provided below the shutter. The flanges formed on the pins 75 and 87 act to prevent the shutter 61 from falling off.

  In the example of FIG. 4, the shutter 61 is held by the support plate 14 in a state in which the three long holes 77, 81, 81 engage with the corresponding pins 75, 87, 87 and can move up and down. The opening portion 76 that is continuous with the elongated hole 77 is an opening portion for releasing the shaft members 93 and 93 of the horizontal moving member 63 and the spring 89, and is cut out in a size that does not hinder the vertical movement of the shutter 61. ing.

  The shutter 61 is formed with two slits 79, 79 cut out in a T shape, for example, at a position where the horizontal moving member 63 is inserted. The slits 79 are elongated hole regions (also referred to as guide portions) that allow the horizontal movement member 63 to move in the vertical direction, and horizontal that disable the horizontal movement member 63 in the vertical direction. 4 to 6 is formed as a T-shaped slit, and in the examples of FIGS. 7 and 8, it is formed as a composite hole composed of a lateral hole region (also referred to as a lock portion) extending in the direction. It is formed as an inverted L-shaped slit. The number of the slits 79 is not particularly limited as long as the slits 79 are provided corresponding to the number of the horizontal moving members 63. In the example of FIG. 4, two slits 79 are formed for the two horizontal moving members 63, but may be one, or three or more.

  This slit 79 is (i) when the plate-shaped members 91 and 91 are contracted by the action of the spring 89 which is an elastic member and the horizontal moving members 63 and 63 are urged against the wall of the horizontal hole region. (Ii) the engaging member 65 moves upward and the horizontal moving member 63 moves horizontally by a predetermined dimension, thereby obstructing the relative movement in the vertical direction. In the state of reaching the region, the horizontal moving member 63 can be relatively moved in the vertical direction to allow the shutter 61 to move upward, and (iii) the engaging member after the relative movement in the upward direction. In a state in which 65 is relatively moved downward and the horizontal moving member 63 returns to the original lateral hole region, the upward movement of the shutter 61 is disabled as in the case (i).

  In addition, a protrusion 83 is provided slightly above the slit 79 so as to come into contact with the tip 68 of the engagement member 65 when the engagement member 65 moves upward. The shape of the protrusion 83 is not particularly limited as long as the protrusion 83 can be brought into contact with the tip 68 of the engaging member 65, and may have a plate shape as shown in FIG. There may be. As described above, the inclined surface 68 of the engaging member 65 brings the horizontal moving member 63 to the long hole region, and the distal end portion 68 of the engaging member 65 pushes up the projection 83, thereby pushing the shutter 61 upward. It is done. Reference numeral 85 denotes an opening, which is provided, for example, when a small protrusion 95 as shown in FIGS. 7 and 8 is provided on the support plate 14. Reference numeral 71 denotes a spring as a third urging member hung between the shutter 61 and the support plate 14, and is provided so as to urge the shutter 61 toward the card discharge port.

  Next, the opening / closing mechanism of the shutter structure 60 according to the first embodiment will be specifically described. 5 and 6 are explanatory views showing an example of an opening / closing mechanism having a shutter structure, and FIGS. 7 and 8 are explanatory views showing another example of the opening / closing mechanism having a shutter structure.

  The shutter structure shown in FIGS. 5 and 6 is the same as that shown in FIG. FIG. 5A shows a stage before the engaging member 65 is engaged from the bottom of the shutter structure 60, and the plate-like members 91 and 91 are contracted by the action of the spring 89, which is an elastic member. 63 are biased to the inner wall of the slit 79 lateral hole region. In this state, since the horizontal moving member 63 is constrained by the lateral hole region, the relative movement of the horizontal moving member 63 in the vertical direction is prevented, and the upward movement of the shutter 61 is impossible.

  FIG. 5B shows that the horizontal movement member 63 slides on the slope 66 of the engagement member 65 by the relative movement of the engagement member 65 in the upward direction, and the horizontal movement member 63 resists the biasing force of the spring 89. It is in a state where it has moved horizontally by a predetermined dimension to reach the slot region. In this state, since the horizontal moving member 63 is not constrained by the lateral hole region, the horizontal moving member 63 can move in the vertical direction, and the shutter 61 can move in the upward direction.

  FIG. 6A shows the state in which the shutter 61 can be moved in the upward direction, the distal end portion 68 of the engaging member 65 abuts against the protruding portion 83, and then the engaging member 65 is further relative to the upward direction. By moving, the shutter 61 is pushed upward as shown in the figure, and the card discharge port is opened. In this state, the horizontal moving member 63 is relatively moved below the elongated hole region of the slit 79.

  FIG. 6B shows a state in which the engaging member 65 after the relative movement in the upward direction relatively moves in the downward direction and the horizontal movement member 63 returns to the original lateral hole region. In this state, similarly to the case of FIG. 4A, the upward movement of the shutter 61 is impossible.

  7 and 8 are explanatory views showing an opening / closing mechanism of the shutter structure when the small protrusion 95 is provided on the support plate 14. In this embodiment, as shown in FIG. 7A, the engaging member 65 relatively moves upward, and the front end 68 extends from the support plate 14 before the position where it abuts against the protrusion 83. A small protrusion 95 is provided. A U-shaped hole through which the small protrusion 95 can be guided is formed at the distal end portion 68 of the engaging member 65. The inner width of the U-shaped hole is larger than that of the small protrusion 95. In this embodiment, the slit shape is an inverted L-shaped slit 80. Note that FIG. 7A and FIG. 8B are the same as the states of FIG. 5A and FIG.

  FIG. 7B is the same as the state shown in FIG. 5B. However, if the U-shaped hole 97 is not formed at the distal end portion 68 of the engaging member 65, the engaging member 65 reaches the predetermined position. The horizontal movement member 63 is designed to have such a size that it cannot move upward and the horizontal moving member 63 cannot reach the elongated hole region of the inverted L-shaped slit 80. Therefore, in FIG. 7B, the small protrusion 95 is in a state of entering the U-shaped hole 97 of the engaging member 65, and the horizontal moving member 63 reaches the slotted hole region of the slit 80 for the first time in this state. The horizontal movement member 63 can be moved in the vertical direction, and the shutter 61 can be moved in the upward direction.

  FIG. 8A shows the state in which the shutter 61 can be moved upward, the tip 68 of the engagement member 65 abuts against the projection 83 and the small projection 95 is the U-shape of the engagement member 65. After entering into the hole 97, the engaging member 65 is further relatively moved upward, so that the shutter 61 is pushed upward as shown in the figure and the card discharge port is opened. In this state, the horizontal moving member 63 is relatively moved below the elongated hole region of the slit 80.

  As shown in FIG. 7 and FIG. 8, a small protrusion 95 is provided in front of the position where the engaging member 65 relatively moves upward and the tip 68 contacts the protrusion 83. Even if an engaging member that does not correspond to the small protrusion 95 or a thin plate having a simple structure is inserted, the small protrusion 95 prevents the entry. As a result, it becomes extremely difficult to open the shutter 61, which is safe in terms of security.

  FIG. 9 is a front view showing another example of the engaging member. The shape of the engaging member 65 is not particularly limited as long as it has an inclined surface 66 that can slide the horizontal moving member 63, and examples thereof include those shown in FIGS. 4 to 8. The complicated form shown in (1) may be used, and the security can be further improved. The engaging member 65 shown in FIG. 9 has a wave shape in which the shape of the inclined surface 66 makes the horizontal movement of the horizontal movement member 63 irregular.

  For example, as shown in FIG. 9A, it may be an engaging member 65A in which a left-right asymmetric waveform is formed on each of the inclined surfaces 66A, 66B, or as shown in FIG. 9B. The engaging member 65B which formed the various waveform shape in the position which each slope does not oppose may be sufficient. That is, in FIG. 9B, the positions of the inclined surfaces 66A and 66D having the waveform shape are the engaging members 65B provided at different positions in the vertical direction. For such an engagement member 65B, the position of the slit provided in the shutter 61 is also provided corresponding to this engagement member 65B, and the position of the horizontal movement member 63 is also corresponding to this engagement member 65B. Will be provided.

  Such engagement members 65A and 65B are provided, and furthermore, by adjusting the relationship between the distance that the horizontal moving member 63 moves horizontally and the position of the slit 79, it is possible to completely open even if a thin plate or the like having a simple shape is used. It is not possible to maintain a very high level of security.

  As described above, according to the card issuing machine according to the first embodiment of the present invention, the shutter structure 60 provided in the card stacker 11 and the engaging member 65 provided in the hopper 21 are engaged. Since the shutter 61 is opened, it is not necessary to insert and remove a key as in the prior art. Further, since the shutter structure 60 constituting the present invention has one or more slits (79, 80) cut out in the inverted L shape or T shape as described above, a predetermined engagement member If 65 is not used, the shutter 61 cannot be opened. As a result, the shutter 61 cannot be opened with a thin plate having a simple structure, which is safe in terms of security.

  Furthermore, according to the present invention, the pin-like horizontal moving member 63 and the slit (79, 80) having an inverted L shape or a T shape formed by a long hole region and a horizontal hole region are engaged. Thus, when the engaging member 65 is relatively moved upward and the horizontal moving member 63 is horizontally moved by a predetermined dimension, the shutter 61 is allowed to move upward, and after the relative movement in the upward direction is performed. When the engaging member 65 is relatively moved downward and the horizontal moving member 63 is returned to the original position, the upward movement of the shutter 61 can be disabled.

  Furthermore, according to the present invention, since the horizontal moving member 63 has the elastic member (spring 89) that urges the wall of the lateral hole region, the engaging member 65 is not engaged and the horizontal moving member 63 is in the original position. In other words, the horizontal moving member 63 that has abutted against the wall of the horizontal hole region by the urging force of the elastic member (spring 89) cannot move upward in the shutter 61. As a result, there is a security merit that the shutter 61 cannot be opened unless the predetermined engaging member 65 is engaged.

  Furthermore, according to the present invention, if the protrusion 95 is provided in front of the position where the engaging member 65 is relatively moved upward and the tip end 68 abuts the protrusion 83, the protrusion 95 is not supported. Even if an engaging member or a thin plate having a simple structure is inserted, the protrusion 95 prevents entry. As a result, the shutter cannot be opened, which is safe in terms of security.

  Furthermore, according to the present invention, the shape of the inclined surface 66 (66A, 66B, 66C, 66D, 66E) of the engaging member 65 (65A, 65B) is a wave shape that makes the horizontal movement of the horizontal movement member 63 irregular. Therefore, by adjusting the relationship between the distance that the horizontal moving member 63 moves horizontally and the position of the slit (79, 80), it is impossible to completely open even using a thin plate having a simple shape. Extremely high security can be maintained.

(Second Embodiment)
FIG. 10 is an explanatory diagram of the shutter structure 160 according to the second embodiment, and FIG. 11 is a perspective view illustrating an example of an engaging member 165 that engages with the shutter structure 160. The shutter structure 160 according to the second embodiment includes the shutter structure 60 according to the first embodiment described above in terms of technical idea.

  As shown in FIG. 10, the shutter structure 160 according to the second embodiment includes a shutter 161 that closes the card discharge port 41 by moving from the open position P to the closed position Q when the card stacker 11 is removed from the hopper 21. Of the four side plates constituting the card stacker 11, the support plate 114 is provided on the card discharge port 41 side to support the movement of the shutter 161, and the support plate 114 is provided with the shutter 161 at the open position P. And at least regulating means for preventing movement. Then, an engaging member 165 having a predetermined shape as shown in FIG. 11 is engaged with the shutter structure 160 from below when the card stacker 11 is mounted on the hopper 21, and the engaging member to the shutter structure 160. By the engagement operation of 165, the shutter 161 moves from the closed position Q to the open position P (see FIG. 2 for the open position P and the closed position Q).

  As shown in FIG. 10, a pair of plate-like arm members (referred to as first arm members 191) are attached to the support plate 114. The first arm member 191 is a member that extends in the vertical direction in which the shutter 161 moves, and includes a first contact member 163 and a first regulating member 164. As shown in FIG. 10, two first arm members 191 may be provided on the support plate 114 (a pair of left and right), or one may be provided on either the left or right side. Alternatively, a total of three may be provided, one on each of the left and right and one of the left and right, or two or more on the left and right. The first arm member 191 constitutes a main part of a restricting means that prevents the shutter 161 from moving to the open position P or releases the restriction.

  The first contact member 163 is a member called the horizontal movement member 63 in the first embodiment, and is provided on the lower end side of the first arm member 191 as shown in FIG. 10 is a member that slides in contact with the slope 166 of the engaging member 165 by relative movement in the vertical direction, and moves horizontally as indicated by the arrow in FIG. In addition, as the 1st contact member 163, as shown in FIG. 10, the pin-shaped member which contacts the slope 166 of the engaging member 165 and is slippery is preferable.

  A first regulating member 164 to be described later is provided at the upper end of the first arm member 191, and the first arm member 191 is placed on the support plate 114 at any part other than the upper and lower ends of the first arm member 191. A shaft member 193 that rotates and horizontally moves the first contact member 163 and the first restriction member 164 is provided. Slightly below the shaft member 193, an urging member (referred to as a first urging member 189) that acts to shrink the space between the first contact members 163 and 163 provided on the pair of first arm members 191 and 191, respectively. ) Is provided.

  The first restricting member 164 is the same member as the first contact member 163 or a separate member, and is a member that prevents the shutter 161 from moving to the open position P. As shown in FIG. 10, the first arm member 191 is used. It is provided on the upper end side of. As the first restricting member 164, as shown in FIG. 10, a pin-shaped member that comes into contact with a first lock portion 198 and a first guide portion 199 described later and is slippery is preferable.

  The shutter structure 160 shown in FIG. 10 is a form in which the first regulating member 164 is provided on the upper end side and the lower end side of the first arm member 191 as a separate member from the first contact member 163. On the other hand, the shutter structure 60 shown in FIG. 4 is a form in which the first regulating member is provided on the lower end side of the plate-like member 91 as the horizontal moving member 63 that is the same member as the first contact member. In the present invention, the first restricting member 164 may be provided as the same member as the first contact member 163 as shown in FIG. 4 as shown in FIG. Although it may be provided as a separate member, when a second arm member 192 described later is provided, the first restricting member 164 is separated from the first contact member 163 as shown in FIG. It is desirable to be provided because of structural limitations.

  The first urging member 189 is provided so that the first contact member 163 contacts and urges the inclined surface 166 of the engaging member 165. If it exhibits such an action, the first urging member 189 having various forms can be employed. In the example shown in FIG. 10, a spring is provided so as to pass between the protruding portions slightly below the shaft member 193 provided on the pair of left and right first arm members 191. In general, a coil spring or the like is preferably used as the first biasing member 189, but biases the first contact member 163 of the first arm member 191 so as to contact the inclined surface 166 of the engaging member 165. If it is a thing, elastic members other than a coil spring can be used.

  Further, in FIG. 10, another spring member (first member) is attached so that one protrusion part of the pair of left and right protrusion parts for stopping the spring and one shaft member of the pair of left and right shaft members 193 are hooked. It is preferable to further provide an adjustment member 190). As the first adjustment member 190 (or the first adjustment spring member), a coil spring or the like is usually preferably used, but an elastic member other than the coil spring may be used. Further, as shown in FIG. 10, in addition to a method of changing the biasing force by applying a first adjustment member 190 made of a coil spring, a method of making it non-uniform using a first adjustment member that combines a strong spring and a weak spring. May be adopted.

  In the first adjustment member 190, when two or more first arm members 191 are provided, at least one of the first arm members 191 is horizontally moved by the first biasing member 189. The biasing member is provided as a biasing member that makes the force at the time and the force when the other first arm member 191 moves horizontally by the first biasing member 189 non-uniformly. By providing the first adjustment member 190, the urging force for at least one first arm member is different from the urging force for the other first arm member, so that the urging force other than the predetermined engagement member 165 provided in the hopper 21 is different. Even if the member attempts to open the shutter 161, the balance between the left and right of the at least two first arm members is lost due to the non-uniform biasing force. As a result, the horizontal movement of the first restricting member 164 deviates from a predetermined dimension. Therefore, the first restricting member 164 is prevented from moving by a first lock portion 198 described later, and the shutter 161 cannot move to the open position P. , Become safer in terms of security.

  The support plate 114 is provided with flange-shaped pins for mounting a shutter 161 that moves up and down. In FIG. 10, a pin 175 that engages with a long hole 177 above the shutter and a pair of left and right pins below the shutter. Are provided with two pins 187 respectively engaged with the long holes 181 and 181 provided in. The flanges formed on the pins 175 and 187 act to prevent the shutter 161 from falling off. Reference numeral 171 denotes a spring as a third urging member hung between the shutter 161 and the support plate 114, and is provided so as to urge the shutter 161 toward the card discharge port.

  In the example of FIG. 10, the shutter 161 is held by the support plate 114 in a state in which the three long holes 177, 181, 181 engage with the corresponding pins 175, 187, 187 and can move up and down. A large opening 176 formed in the central region of the shutter 181 is an opening for releasing the shaft members 193 and 193 and the first biasing member 189 of the first contact member 163, and prevents the shutter 161 from moving up and down. Cut out in a size that does not become.

  Also, above the shutter 161, as shown in FIG. 10, a slit-shaped first lock portion 198 having a wall end surface extending in the horizontal direction and a slit-shaped first guide portion 199 having a wall end surface extending in the vertical direction. And are provided. The first lock portion 198 and the first guide portion 199 correspond to the two slits 79 and 79 cut out in a T shape in the first embodiment shown in FIG. In other words, the shutter 161 is formed with a slit cut into, for example, a substantially T-shape at a position where the pin-shaped first regulating member 164 that moves horizontally is inserted. The slits are a first lock portion 198 which is a horizontal hole region extending in the horizontal direction that disables the relative movement of the shutter 161 and the first restricting member 164 in the vertical direction, and the vertical direction of the shutter 161 and the first restricting member 164. The first guide portion 199 is a long hole region extending in the vertical direction that enables relative movement of the first guide portion 199. In the examples of FIGS. 12 to 16, the slit is formed as a substantially T-shaped slit. Yes. Such slits may be substantially L-shaped as well as inverted L-shaped, and the number of slits is not particularly limited as long as it is provided corresponding to the number of first regulating members 164. In the example of FIG. 10, two substantially T-shaped slits are formed above the shutter 161 for the two first regulating members 164.

  More specifically, the first lock portion 198 acts to abut against the first restricting member 164 when the shutter 161 is in the closed position Q to prevent the shutter 161 from moving to the open position P. At this time, “when the shutter 161 is in the closed position Q” means that the first contact member 163 is not in contact with the engagement member 165 and the engagement member 165 pushes the shutter 161 upward to the open position P. This is the case. In this case, since the first arm member 191 does not rotate around the shaft member 193, the first restricting member 164 provided on the upper end side is a wall end surface 198A extending in the horizontal direction constituting the first lock portion 198. It is prevented from moving up and down.

  The first lock portion 198 also acts to release the hindrance to the movement of the shutter 161 to the open position P when the first contact member 163 contacts the engagement member 165 and moves horizontally by a predetermined dimension. At this time, “when the first contact member 163 contacts the engaging member 165 and moves horizontally by a predetermined dimension” means that the first contact member 163 contacts the engaging member 165 and the first contact member 163 is the shaft. This is the case where the member 193 is moved horizontally in the horizontal direction by a predetermined dimension and reaches the position guided by the first guide portion 199. In this case, the first restricting member 164 provided on the upper end side of the first arm member 191 is separated from the horizontally extending wall end surface 198A constituting the first lock portion 198 and is guided by the first guide portion 199. Therefore, the shutter 161 can be moved in the vertical direction, and the hindrance to the movement to the open position P is released.

  On the other hand, the first guide portion 199 acts to guide the relative movement of the first restricting member 164 from the closed position Q to the open position P when the hindrance to the movement of the shutter 161 to the open position P is released. To do. At this time, “when the hindrance to the movement of the shutter 161 to the open position P is released” means that the engagement member 165 is engaged with the shutter structure 160 and the first contact member 163 moves horizontally by a predetermined dimension. is there. In this case, the first restricting member 164 provided on the upper end side of the first arm member 191 is separated from the wall end surface 198A extending in the horizontal direction constituting the first lock portion 198 and is guided by the first guide portion 199. As a result, the shutter 161 can be moved in the vertical direction, and the first restricting member 164 guides the relative movement from the closed position Q to the open position P.

  The slit notched in an inverted L-shape or T-shape formed of the first lock portion 198 and the first guide portion 199 is (i) the first arm member by the action of the spring as the first biasing member 189. In a state in which the distance between the upper end portions of 191 and 191 is increased and the first restricting members 164 and 164 are biased by the wall end surface 198B extending in the longitudinal direction of the first lock portion 198, the first restricting member 164 is the first lock member. Since the wall end surface 198A extending laterally of the portion 198 is prevented from moving in the vertical direction, the shutter 161 cannot be moved to the open position P, and (ii) the engaging member 165 is relatively moved in the upward direction to cause the first movement. In a state where the restricting member 164 moves horizontally by a predetermined dimension and reaches the elongated hole region of the first guide portion 199, the first restricting member 164 can be relatively moved in the vertical direction, so that the shutter 161 is moved to the open position P. Can be moved, and (iii) In a state in which the engaging member 165 after the relative movement in the upward direction is relatively moved in the downward direction and the first restricting member 164 returns to the lateral hole region of the original first lock portion 198, Similarly, the shutter 161 cannot be moved to the open position P.

  Further, a shutter 161 as a part of an opening continuous with the slit is slightly above the slit formed in the inverted L-shape or T-shape formed by the first lock portion 198 and the first guide portion 199. Is provided with a long hole 177 corresponding to a flange-shaped pin 175 for mounting to the support plate 114. The long hole 177 is engaged with the flange of the pin 175 to prevent the shutter 61 from falling off.

  A pair of left and right elongated holes 181 and 181 are provided below the shutter 161, and the support plate 114 is provided with two pins 187 and 187 that engage with the respective elongated holes 181 and 181. The shutter 161 is held by the support plate 114 so that the three long holes 177, 181 and 181 are engaged with the corresponding pins 175, 187 and 187 and can move up and down.

  The shutter 161 is provided with a protrusion 183 that contacts the concave contact portion 184 of the engagement member 165 when the engagement member 165 moves upward. The shape of the protrusion 183 is not particularly limited as long as the protrusion 183 can be brought into contact with the tip 168 of the engaging member 165. The protrusion 183 may have a pin shape or a plate shape as shown in FIG. There may be. As described above, the inclined surface 168 of the engaging member 165 horizontally moves the first contact member 163 by a predetermined distance in the horizontal direction, and the distal end portion 168 of the engaging member 165 pushes up the protruding portion 183 so that the shutter 161 is moved. Pushed up.

  Next, the second arm member 291 will be described. The second arm member 291 is a member unique to the second embodiment, and is provided to further improve the security of the shutter structure 160.

  As shown in FIG. 10, the second arm member 291 is a pair of plate-like arm members, and is attached to the support plate 114 in the same manner as the first arm member 191. The second arm member 291 is a member that extends in the vertical direction in which the shutter 161 moves and is provided adjacent to the outside of the first arm member 191, and includes a second contact member 263 and a second restriction member 264. It is. As shown in FIG. 10, two second arm members 291 may be provided on the support plate 114 (a pair of left and right), or one may be provided on either the left or right side. Alternatively, a total of three may be provided, one on each of the left and right and one of the left and right, or two or more on the left and right. The second arm member 291 constitutes a main part of a restricting unit that prevents the shutter 161 from moving to the open position P or releases the restriction.

  The second contact member 263 is a member that operates in the same manner as the first contact member 163. As shown in FIG. 10, the second contact member 263 is provided on the lower end side of the second arm member 291 and moves the engagement member 165 in the vertical direction. Is a member that slides in contact with the inclined surface 166 of the engagement member 165 by relative movement, and moves horizontally as indicated by an arrow in FIG. As the second contact member 263, as shown in FIG. 10, a pin-shaped member that contacts the slope 166 of the engaging member 165 and easily slides is preferable.

  A second regulating member 264 described later is provided at the upper end of the second arm member 291, and the second arm member 291 is placed on the support plate 114 at any part other than the upper and lower ends of the second arm member 291. A shaft member 293 that rotates and horizontally moves the second contact member 263 and the second restriction member 264 is provided. A biasing member (referred to as a second biasing member 289) that acts so as to shrink the space between the second contact members of the pair of second arm members 291 and 291 is provided slightly below the shaft member 293.

  The second restricting member 264 is a member that prevents the shutter 161 from moving to the open position P, and is provided on the upper end side of the second arm member 291 as shown in FIG. As the second restricting member 264, as shown in FIG. 10, a pin-shaped member that comes into contact with a second lock portion 298 and a second guide portion 299, which will be described later, and is slippery is preferable.

  The second urging member 289 is provided so that the second contact member 263 contacts and urges the inclined surface 166 of the engaging member 165. As long as such an effect is exhibited, the second urging member 289 having various forms can be employed. In the example illustrated in FIG. 10, the shaft member 293 is provided adjacent to the second arm member 291. Specifically, as shown in FIG. 10, a fixing pin 293A provided slightly below the shaft member 293 provided on the pair of left and right first arm members 291 and a second arm member 291 slightly above the shaft member 293. A spring-shaped second urging member 289 for rotating the fixing pin 293 </ b> B provided above through the shaft member 293 is provided. The second urging member 289 is not limited to such a configuration, and may be any member that urges the second contact member 263 of the second arm member 291 to contact the inclined surface 166 of the engaging member 165. Various elastic members can be used.

  Further, if the strength of the second urging member 289 provided on the left and right second arm members 291 is changed, at least one second arm member 291 among the plurality of second arm members 291 is the second urging member 289. Therefore, the force when moving horizontally by the second biasing member 289 and the force when moving horizontally by the second urging member 289 can be made non-uniform. Further, the forces of the second urging members 289 and 289 provided on the left and right second arm members 291 and 291 are unbalanced by changing the strength of the left and right springs or changing the number of left and right springs, for example. May be. Such a non-uniform biasing member is referred to as a second adjustment member (or second adjustment spring member). Such a second adjusting member may or may not be provided, but is preferably provided from the viewpoint of safer security. In the case where the second adjustment member is provided, even if an attempt is made to open the shutter 161 with a member other than the predetermined engagement member 165 provided in the hopper 21, the left and right of the at least two second arm members are caused by a non-uniform biasing force. Is out of balance. As a result, the horizontal movement of the second restricting member 264 deviates from a predetermined dimension. Therefore, the second restricting member 264 is prevented from moving by a second lock portion 298 described later, and the shutter 161 cannot move to the open position P. , Become safer in terms of security.

  Further, as shown in FIG. 10, a second lock portion 298 having a wall end surface 298A extending in the horizontal direction and a second guide portion 299 having a wall end surface 299A extending in the vertical direction are provided above the shutter 161. ing. The second lock portion 298 and the second guide portion 299 are notched into an inverted L shape or a T shape. That is, the shutter 161 is cut out in an inverted L shape as shown in FIG. 10, for example, at the position of the pin-shaped second regulating member 264 that moves horizontally. The notch includes a second lock portion 298 having a wall end surface 298A extending in the horizontal direction that disables the relative movement of the shutter 161 and the second restricting member 264 in the vertical direction, and the shutter 161 and the second restricting member 264. And a second guide part 299 having a wall end surface 299A extending in the vertical direction that enables relative movement in the vertical direction. In the examples of FIGS. Such a notch may be substantially T-shaped in addition to the inverted L-shape, and the number thereof is not particularly limited as long as it is provided corresponding to the number of the second restricting members 264. In the example of FIG. 10, two inverted L-shaped notches are formed on the left and right sides above the shutter 161 with respect to the two second restricting members 264.

  More specifically, the second lock portion 298 contacts the wall end surface 298A of the second regulating member 264 when the second contact member 263 contacts the inclined surface 166 of the engaging member 165 and moves horizontally by a predetermined dimension. It acts to prevent 161 from moving to the open position P. At this time, “when the second contact member 263 contacts the engagement member 165 and moves horizontally by a predetermined dimension” means that the second contact member 263 contacts the inclined surface 166 of the engagement member 165 and the second contact member 263. As a result of the horizontal movement in the horizontal direction of the predetermined dimension around the shaft member 293, the second restricting member 264 moves in the horizontal direction of the predetermined dimension in the direction opposite to the moving direction of the second contact member 263 around the shaft member 293. The second restricting member 264 reaches the wall end surface 298 </ b> A extending in the horizontal direction constituting the second lock portion 298 from the position guided by the second guide portion 299. In this case, the second restricting member 264 provided on the upper end side of the second arm member 291 reaches the wall end surface 298A constituting the second lock portion 298 from the position guided by the second guide portion 299. The shutter 161 cannot be moved in the vertical direction, and the movement to the open position P is prevented.

  In addition, the second lock member 298 has a second restriction member 263 as a result of the second contact member 263 contacting the narrow portion 186 of the engagement member 165 after the second contact member 263 contacts the slope 166 of the engagement member 165. When the H.264 moves horizontally by a predetermined dimension in the direction away from each other, it also acts to release the hindrance to the movement of the shutter 161 to the open position P. In this case, the second restricting member 264 provided on the upper end side of the second arm member 291 is separated from the horizontally extending wall end surface 298A constituting the second lock portion 298 and is guided by the second guide portion 299. Therefore, the shutter 161 can be moved in the vertical direction, and the hindrance to the movement to the open position P is released.

  On the other hand, when the second contact member 263 does not contact the inclined surface 166 of the engaging member 165 or when the second guide member 299 contacts the engaging member 165 and moves horizontally by a dimension other than the predetermined dimension, the second restricting member H.264 is allowed to move to the open position P without contacting the H.264. At this time, “when the second contact member 263 does not contact the inclined surface 166 of the engagement member 165” is when the second contact member 263 and the engagement member 165 do not engage with each other, “When the second contact member 263 contacts the inclined surface 166 of the engagement member 165 after the second contact member 263 contacts the inclined surface 166 of the engagement member 165”. This is when the narrow portion 186 is contacted. In this case, the second restricting member 264 provided on the upper end side of the second arm member 291 is separated from the horizontally extending wall end surface 298 </ b> A constituting the second lock portion 298 and is guided by the second guide portion 299. As a result, the shutter 161 can be moved in the vertical direction.

  The notch having an inverted L shape or T shape formed of the second lock portion 298 and the second guide portion 299 is (i) an upper end portion of the second arm members 291 and 291 by the action of the second urging member 289. In the state in which the distance between the second restriction member 264 and the second restriction member 264 is increased, the second restriction member 264 is located in the second guide portion 299, so that the second restriction member 264 can be moved in the vertical direction. (Ii) The engaging member 165 moves relatively upward to contact the second contact member 263, and the second restricting member 264 moves horizontally by a predetermined dimension to the wall end surface 298A of the second lock portion 298. In the reached state, the relative movement in the vertical direction of the second restricting member 264 is hindered, so that the movement of the shutter 161 to the open position P becomes impossible, and (iii) the engagement member 165 further moves in the upward direction. The second contact member 263 is an engaging member. In the state where the second restricting member 264 comes into contact with the 65 narrow width portion 186 and the second restricting member 264 moves horizontally by a predetermined dimension and returns to the second guide portion 299, the second restricting member 264 can move in the vertical direction. The shutter 161 can be moved to the open position P.

  The second contact member 263 included in the second arm member 291 is disposed at a position closer to the closed position Q of the shutter 161 than the first contact member 163 included in the first arm member 191 as illustrated in FIG. Is preferred. The engaging member 165 engages with the shutter mechanism from below, but the engaging member 165 contacts the second contact member 263 before the first contact member 163 that pushes up the shutter 161 and opens the shutter 161 at the open position P. Restrict movement to As a result, the movement of the shutter 161 to the open position P can be regulated twice, which is more preferable from the viewpoint of security. Since the second contact member 263 and the first contact member 163 have the above positional relationship, the second arm member 291 having the second contact member 263 at the lower end is bent near the lower end, The second contact members 263 and 263 included in the second arm members 291 and 291 are adapted to approach each other.

  As shown in FIGS. 10 and 11, the engaging member 161 abuts on a protrusion 183 included in the shutter 161 to push the shutter 161 to the open position P, and the contact 184 becomes a protrusion 183. The second contact member 263 comes into contact with the second urging member 289 when the shutter 161 is pushed up to push up the shutter 161, and has a narrow portion 186 extending in the vertical direction. The engaging member 165 having the abutting portion 184 and the narrow width portion 186 can abut on the projection portion 183 included in the shutter 161 to push the shutter 161 up to the open position P. Even if a thin plate or the like having a structure is inserted, the protrusion 161 provided in the shutter 161 can prevent entry. As a result, the shutter 161 cannot be opened, which is safe in terms of security.

  Next, the opening / closing mechanism of the shutter structure 160 according to the second embodiment will be specifically described. 12-16 is explanatory drawing of the opening / closing operation | movement of the shutter structure 160. FIG.

  The shutter structure 160 shown in FIGS. 12 to 16 is the same as that shown in FIG. FIG. 12 is a stage before the engaging member 165 is engaged from below the shutter structure 160, and the first contact on the lower end side of the first arm members 191, 191 by the action of the spring as the first urging member 189. The first contact members 163 and 163 are biased by the wall end surface 161A of the shutter 161 processed to have a predetermined width by contracting between the members 163. At the same time, the second contact members 263 on the lower end side of the second arm members 291 and 291 are also contracted, and the second contact members 263 and 263 are also urged by the wall end surface 161A of the shutter 161 processed to a predetermined width. . If an attempt is made to open the shutter 161 in this state, the first restricting member 164 on the upper end side of the first arm member 191 contacts the wall end surface 198A extending in the horizontal direction of the first lock portion 198, so that the shutter 161 moves upward. Thus, the movement to the open position P is prevented.

  FIG. 13 is a first stage in which the engaging member 165 is engaged from the bottom of the shutter structure 160, and the second contact member 263 is moved to the inclined surface of the engaging member 165 by the relative movement of the engaging member 165 upward. When the second contact member 263 moves horizontally by a predetermined dimension against the urging force of the spring 289 (see FIG. 10) as the second urging member, the second contact member 263 is provided on the upper end side of the second arm member 291. The second restricting member 264 also moves horizontally by a predetermined dimension to the opposite side. Due to this horizontal movement, the second restriction member 264 prevents the relative movement of the second restriction member 264 from the position of the second guide part 299 that allows the second restriction member 264 to move relatively up and down. 2 Moves to the position of the lock part 298. In this state, the relative movement in the vertical direction of the second restriction member 264 is hindered, and the movement of the shutter 161 to the open position P is disabled by the second restriction member 264. At this time, the movement of the shutter 161 to the open position P is also disabled by the first restricting member 164.

  In the illustrated example, a pair of the second arm member 191, the second lock portion 298, and the second guide portion 299 are provided symmetrically in the left-right direction, but may not be left-right symmetrical, or only one side may be provided on both sides. Three or more may be provided asymmetrically or symmetrically. In short, at this stage, it is only necessary that at least one second restricting member 264 moves horizontally to a position where it abuts on the second lock portion 298, and the relative movement of the second restricting member 264 in the vertical direction is prevented.

  FIG. 14 is a second stage in which the engaging member 165 is engaged from the bottom of the shutter structure 160, and the second contact member 263 is moved further upward by the relative movement of the engaging member 165. The side wall 165A is slid without changing the width, the second restricting member 264 is held at a position where it abuts against the second lock portion 298, and the relative movement in the vertical direction of the second restricting member 264 is hindered to open the shutter 161 at the open position P. The second restricting member 264 makes it impossible to move to.

  At this time, the first contact member 163 slides on the slope 166 of the engagement member 165 by the relative movement of the engagement member 165 upward, and the first contact member 163 is a spring of the first biasing member 189. When the horizontal movement with a predetermined dimension is performed against the urging force, the first regulating member 164 provided on the upper end side of the first arm member 191 also moves horizontally with a predetermined dimension on the opposite side. By this horizontal movement, the first restricting member 164 allows the first restricting member 164 to move up and down from the position of the first lock portion 198 that prevents the first restricting member 164 from moving up and down relatively. It moves to the position of one guide part 199. In this state, since there is nothing that prevents the relative vertical movement of the first restricting member 164, the movement of the shutter 161 to the open position P is not disabled by the first restricting member 164, but the open position of the shutter 161. The movement to P is prevented by the second restriction member 264 described above.

  Even at this stage, in the example shown in the figure, the second arm member 191, the second lock portion 298, and the second guide portion 299 are provided in a bilaterally symmetric manner. Or three or more of them may be provided asymmetrically or symmetrically on both sides. In short, at this stage, even when all the first restricting members 164 move horizontally to a position where the shutter 161 can move up and down, the position where at least one second restricting member 264 contacts the second lock portion 298. It is only necessary that the second regulating member 264 is prevented from relative movement in the vertical direction.

  FIG. 15 shows a third stage in which the engaging member 165 is engaged from the bottom of the shutter structure 160, and the second contact member 263 is moved further upward by the relative movement of the engaging member 165. The narrow portion 186 is reached. The narrow width portion 186 of the engaging member 165 is substantially the same as the width between the wall end surfaces 161A of the shutter 161 where the second contact member 263 is biased by the first biasing member 189. The member 264 returns from the position of the second lock portion 298 that prevents the relative movement of the second restricting member 264 to the position of the second guide portion 299 that enables the relative movement of the second restricting member 264. The second regulating member 264 can move the shutter 161 to the open position P.

  At this time, the first contact member 163 reaches the side wall 165A from the inclined surface 166 of the engaging member 165, and slides on the side wall 165A without changing the width. While the first contact member 163 slides on the side wall 165A, the first restricting member 164 is in the position of the first guide portion 199, so that the shutter can be freely moved up and down with respect to the first restricting member 164. It has become. When the first contact member 163 slides on the side wall 165A and the second contact member 263 reaches the narrow portion 186 of the engagement member 165, as shown in FIG. And the second restricting member 264 are located in the first guide portion 199 and the second guide portion 299, respectively, the movement of the shutter 161 to the open position P is the same as the first restricting member 164 and the second restricting member 264. This is possible for both members 264.

  FIG. 16 shows a fourth stage in which the engaging member 165 is engaged from the bottom of the shutter structure 160. When the engaging member 165 further moves upward, the U-shaped groove provided at the tip of the engaging member 165 is shown. The protrusion 183 hits the inner contact portion 184 and the shutter 161 moves upward to be pushed up to the open position P. At this time, when the shutter 161 moves upward, the first restricting member 164 enters the elongated hole region of the first guide portion 199, so that the first contact member 163 is thereafter engaged with the engaging member 165 as shown in FIG. Even when the first narrowing portion 186 is reached, the first restricting member 164 moves relative to the first guide portion 199 in the vertical direction and does not hinder the vertical movement of the shutter 161.

  The movement when the engaging member 165 engaged from the bottom of the shutter structure 160 is removed is the reverse of the operation of the shutter structure 160 shown in FIGS.

  FIG. 17 is a front view illustrating another example of the engaging member according to the second embodiment. The shape of the engaging member 165 is not particularly limited as long as it has an inclined surface 166 and a narrow width portion 186 that can slide the first contact member 163 and the second contact member 263, and has the form shown in FIG. Although the complicated form shown in FIG. 17 may be used, the security can be further improved. The engaging member shown in FIG. 17 has a wave shape that makes the horizontal movement of the first contact member 163 and the second contact member 263 irregular.

  For example, as shown in FIG. 17A, it may be an engaging member 165A having a left-right asymmetric waveform shape formed on each of the inclined surfaces 166A, 166B, or as shown in FIG. The engaging member 165 </ b> B may be formed with a simple corrugated shape formed at a position where each inclined surface is not opposed. That is, in FIG. 17B, the positions of the inclined surfaces 166A and 166D having a waveform shape are the engaging members 165B provided at different positions in the vertical direction. For such an engagement member 165B, the positions of the first contact member 163 and the second contact member 263 provided on the shutter 161 are also provided corresponding to the engagement member 165B. Further, such a corrugated shape may be formed in the narrow width portion 186 as shown in FIG.

  By providing such engagement members 165A and 165B, and further adjusting the relationship between the distance that the first contact member 163 and the second contact member 263 move horizontally and the position of each lock portion and guide portion, a simple shape can be obtained. Even if a thin plate or the like is used, it cannot be opened at all, and extremely high security can be maintained.

  As described above, according to the card issuing machine according to the second embodiment of the present invention, the shutter 161 is opened by the engagement of the shutter structure 160 included in the card stacker 11 and the engaging member 165 included in the hopper 21. Therefore, it does not take the trouble of inserting and removing the key as in the prior art. Further, the shutter structure 160 constituting the present invention has a pin-shaped first restricting member 164 that prevents the shutter 161 from moving to the open position P, and a first lock that restricts the operation of the first restricting member 164. Since the portion 198 and the first guide portion 199 are provided, the shutter 161 cannot be opened unless the predetermined engagement member 165 that contacts the first contact member 163 and restricts the movement of the first restriction member 164 is used. As a result, the shutter 161 cannot be opened with a thin plate having a simple structure, which is safe in terms of security.

  Furthermore, according to the present invention, the pin-shaped second contact member 263 that moves horizontally by sliding on the inclined surface 166 of the engaging member 165, and the pin shape that prevents the shutter 161 from moving to the open position P. The second contact member 263 includes the second arm member 291 having the second restricting member 264 and the second lock portion 298 and the second guide portion 299 that restrict the operation of the second restricting member 264. The shutter 161 cannot be opened without using a predetermined engaging portion 166 material that is in contact with the second restriction member 264 and restricts the movement of the second restriction member 264. That is, according to the present invention, the shutter 161 can be opened only when the engaging member 165 is engaged with the first contact member 163 and the second contact member 263 at a predetermined position. With a thin plate or the like, the shutter cannot be opened, which is more secure in terms of security.

Further, according to the present invention, the engaging member 165 having the contact portion and the narrow width portion can contact the protrusion provided in the shutter 161 to push the shutter 161 up to the open position P. Even if a joint member or a thin plate having a simple structure is inserted, the protrusion prevents the entry. As a result, the shutter cannot be opened, which is safe in terms of security.
Furthermore, according to the present invention, the shape of the inclined surface 166 of the engaging member 165 is a wave shape that makes the horizontal movement of the first contact member 163 and the second contact member 263 irregular, and therefore the first contact member 163 and By adjusting the relationship between the distance that the second contact member 263 moves horizontally and the positions of the first lock portion 198, the first guide portion 199, the second lock portion 298, and the second guide portion 299, a simple operation can be performed. Even if a thin plate or the like is used, it cannot be opened completely, and extremely high security can be maintained.

(Card sending means)
Next, the card sending means will be briefly described. The card sending means 51 is a device that is opposed to the bottom of the card stacker 11 and sends out the card 47 placed at the bottom of the plurality of cards 1 to the outside of the card stacker 11. The form shown in FIG. 1 is an example, and is not necessarily limited to the form of FIG.

And a delivery roller 42 that contacts the surface of the card 47 being pushed out and feeds the card 47 out of the card stacker 11. The push-out member 33 has a push-up portion 37 that pushes up the other card 1b placed on the bottommost card 47, and the push-up portion 37 causes the card 47 to be pushed out from above. It can be easily extruded without pressure. The pushing member 33 and the push-up portion 37 may be provided as separate bodies.

  The pushing member 33 is attached to a chain 34 spanned between two sprockets 30 and 32, for example. Specifically, the pushing member 33 constitutes a part of the link of the chain 34 that is spanned between the drive sprocket 30 and the driven sprocket 32. In the vicinity of the chain 34, a chain guide 35 for preventing the chain 34 and the pushing member 33 from sinking is provided. In FIG. 1, two sprockets 30 and 32 are used. However, the sprocket 30 or 32 may be composed of three or more sprockets. The drive sprocket 30 is driven by a driving means such as a stepping motor.

  The delivery roller 42 is provided near the outside of the card discharge port 41 arranged in the direction in which the bottommost card 47 is pushed out. The delivery roller 42 is a roller for contacting the surface of the card 47 being pushed out by the pushing member 33 and feeding the card 47 out of the card stacker 11, and is driven by a driving means such as a stepping motor.

  As shown in FIG. 1, it is preferable that an opposing roller 43 that sends out the card 47 in cooperation with the sending roller 42 is provided at a position facing the sending roller 42. The opposing roller 43 applies a frictional force between the card 47 and the delivery roller 42 by pressing the card 47 to be delivered downward. Such a frictional force ensures that the card 47 is fed out.

  A pair of members for allowing only one card to pass through is preferably provided on the sending roller 42 side of the bottom of the card stacker 11. FIG. 1 shows an example in which a reference plate 45 along the inner wall of the card stacker 11 is disposed on the upper side, and a reference plate 44 extending in the sending direction is disposed on the lower side. The pair of members (reference plates 44 and 45) are disposed in opposition to each other in the vicinity of the inside of the card discharge port 41 with a predetermined gap through which only one card can pass. The gap is dimensioned so that only one card passes and the card above it does not pass. The reference plates 44 and 45 are preferably made of a material that does not easily wear.

  The card issuing machine 10 of the present invention includes a driver that drives the stepping motor and a control unit that outputs a position command or a speed command to the driver.
