  Further, at a position adjacent to the tag catcher 2, a vertically long coin passage 3 having a coin insertion slot 3 </ b> A on the upper side and a coin payout opening 3 </ b> B on the lower side that is slightly wider than the thickness of the substantially coin a is provided. ing. On the rear wall surface of the coin passage 3 on the coin insertion slot 3A side, three vertically elongated hole portions 9 are formed vertically, and via a support shaft 10 disposed sideways so as to penetrate the vertically elongated hole portion 9, Three coin checkers 6 each having a lower protrusion 6B and an upper protrusion 6A are supported in a swingable manner.

  As shown in FIG. 4, each coin checker 6 is in a free rotation state around the support shaft 10, but is always restricted to rotate clockwise around the support shaft 10. Each lower protrusion 6B protrudes from the vertically long hole portion 9 toward the coin passage 3 side, and each upper protrusion 6A can always maintain a state of being retracted from the vertically long hole portion 9 to the coin passage 3 rear side.

  The two sides of the coin checker 6 are formed integrally with the L-shaped coin shutter 7, and the coin checker 6 swings sideways on the upper side of the three vertically long holes 9 as the coin shutter 7 swings. The one end side of the L-shaped piece protrudes toward the coin passage 3 from the horizontally elongated hole portion 11 formed as described above or retreats to the rear side of the coin passage 3.

  At a position between the tag catcher 2 and the coin passage 3 and adjacent to the coin checker 6, a coin checker 6 side locking arm piece 4B at one end and a tag catcher side locking claw 4A at the other end. The lock lever 4 is arranged so as to be swingable through a central support shaft 12. Before the coin a is inserted from the coin insertion slot 3A, as shown in FIGS. 3 and 4, the coin of the lock lever 4 is moved by the upper protrusion 6A retracted to the rear side of the coin passage 3 of the coin checker 6. At the same time that the checker side locking arm piece 4B is locked, the tag catcher side locking claw 4A of the lock lever 4 is suspended from the deep groove engaging recess 2C of the tag catcher 2.

  On the other hand, when the coin a is inserted, as shown in FIGS. 5 and 6, each lower protrusion 6 </ b> B of the coin checker 6 is pushed backward by the coin a to the vertically long hole 9, and the coin insertion slot 3 </ b> A is pressed by the coin shutter 7. Is closed, and the upper protrusion 6A is pulled into the vertically long hole 9 so that the coin checker side locking claw 4B of the lock lever 4 is disengaged from the upper protrusion 6A and the lock lever 4 is moved around the support shaft 12. The tag catcher 2 can be rotated counterclockwise by rotating clockwise and the tag catcher side engaging claw 4A of the lock lever 4 being separated from the deep groove engaging recess 2C.

  The rocking range of the lock lever 4 itself is restricted by loosely fitting a stationary pin 12B provided at a projecting portion in the approximate center of the lock lever 4 into a loose coupling hole 12A formed near the support shaft 12. . That is, as shown in FIG. 3, in the unlocked state of the latch lever 2A, the stationary pin 12B is located at one end (right side in the figure) of the idler hole 12A in front of the first coin locking portion 5A above the coin stopper 5 ( It is located in a state slightly protruding in the direction of the coin passage 3). When the coin a is inserted into the coin passage 3 from the coin insertion slot 3A, the stationary pin 12B is pushed by the gravity of the coin a and retracted to the other end of the loose hole 12A, and at the same time the lock lever 4 is pivoted. It is assumed that it rotates clockwise around twelve.

  Further, in the vicinity of the lock lever 4, a second coin locking portion 5 </ b> B as a secondary holding of the coin a protrudes sideways through a slightly long arm so as to slightly overlap the lock lever 4. A coin stopper 5 is formed on the other end, and is formed with a first coin locking portion 5A as a primary storage for the coin a projecting laterally through a slightly short arm in the same manner as described above. It is arranged so that it can swing. The coin stopper 5 itself is always urged to rotate clockwise through a spring 8 disposed on the first coin locking portion 5A side.

  When a coin a is inserted from the coin insertion slot 3A, the coin a first hits the stationary pin 12B of the lock lever 4 and is pushed to slide the idle hole 12A, and then the first coin is locked. As described above, the tag catcher-side locking claw portion 4A of the lock lever 4 is separated from the deep groove engaging recess 2C when locked by the portion 5A and in the primary holding state. Then, as shown in FIG. 7, when the tag catcher 2 is slightly rotated counterclockwise, the first portion of the coin stopper 5 is changed from the deep groove first recess 2D to the shallow groove second recess 2E. A locking projection 5C on the opposite side of the two coin locking portion 5B is suspended. Further, as shown in FIGS. 8 and 9, when the tag catcher 2 is rotated in the same direction, the locking projection 5 </ b> C is released from the second recess 2 </ b> E having a shallow groove and is placed on the outer peripheral surface of the tag catcher 2. After the coin a is detached from the first coin locking portion 5A and dropped, the coin a is locked by the second coin locking portion 5B located below the coin passage 3 of the coin stopper 5 to enter the secondary holding state. At the same time, the latch lever 2A is locked.

  Further, as shown in FIG. 10, when the tag catcher 2 is rotated counterclockwise from the secondary holding state to unlock the latch lever 2A, the shallow groove engaging recess 2B and the deep groove of the tag catcher 2 are unlocked. The tag catcher side locking claw 4A of the lock lever 4 moves in the order of the engaging recess 2C, and at the same time, the locking protrusion 5C on the opposite side of the second coin locking portion 5B of the coin stopper 5 has a shallow groove. The second concave portion 2E and the deep groove first concave portion 2D are moved in this order, and the coin stopper 5 is rotated clockwise around the support shaft 12 so that the coin a is detached from the second coin engaging portion 5B and is secondary. It is assumed that the hold state is released and falls to the coin refund port 3B side. During the unlocking of the latch lever 2A, the tag catcher side latching claw portion 4A of the lock lever 4 is suspended in the shallow groove engaging recess 2B of the tag catcher 2, and the tag catcher 2 is rotated counterclockwise. This prevents rotation, that is, prevents re-locking by the latch lever 2A.

  As shown in FIG. 3, the coin checker side locking arm piece 4B of the lock lever 4 is locked by the upper protrusion 6A retracted to the rear side of the coin passage 3 of the coin checker 6, and at the same time the stationary pin 12B. Also slides to one end of the idle hole 12A, and the coin shutter 7 of the coin insertion slot 3A is opened, and at the same time, the tag catcher side engaging claw 4A of the lock lever 4 is inserted into the deep groove engaging recess 2C of the tag catcher 2. Is suspended, the state before the coin a is inserted from the coin insertion slot 3A is restored.

  Next, an example of use and operation of the best mode configured as described above will be described. Before the coin a is inserted from the coin insertion slot 3A, as shown in FIGS. At the same time that the coin checker side locking arm piece 4B of the lock lever 4 is locked by the upper projection 6A retracted to the rear side of the coin passage 3 of the checker 6, the lock lever is inserted into the deep groove engaging recess 2C of the tag catcher 2. 4 tag catcher side latching claw part 4A is suspended. At this time, when the fixed pin 12B of the lock lever 4 is located at one end (right side in FIG. 3) of the mating hole 12A in a state slightly protruding in front of the first coin locking portion 5A above the coin stopper 5. At the same time, a locking protrusion 5C below the coin stopper 5 is suspended in the first recess 2D of the tag catcher 2. The rotation operation unit is in a state where it cannot be removed from the tag catcher 2.

  On the other hand, when the coin a is inserted from the coin insertion slot 3A at the time of locking, as shown in FIGS. 5 and 6, each lower projection 6B of the coin shutter 7 is pushed backward by the coin a to the vertically long hole portion 9, The coin insertion slot 3 </ b> A is closed by the coin shutter 7. Then, the upper protrusion 6A is pulled into the vertically long hole 9, the coin checker side locking arm piece 4B of the lock lever 4 is disengaged from the upper protrusion 6A, and the stationary pin 12B located at one end of the loose hole 12A is a coin. The lock lever 4 is pushed by the weight of a and retracted to the other end of the loose hole 12A, so that the lock lever 4 rotates clockwise around the support shaft, and the tag catcher side latching claw portion 4A of the lock lever 4 is a deep groove. It separates from the engaging recess 2C. In this state, the latch lever 2A is locked by rotating the tag catcher 2 counterclockwise via the inserted rotation operation unit.

  At this time, the coin a inserted from the coin insertion slot 3A is in a state in which the stationary pin 12B is first withdrawn to the rear of the first coin locking portion 5A of the coin stopper 5, thereby causing the first coin locking portion 5A to move to the first coin locking portion 5A. The locked primary holding state is established. Then, as shown in FIGS. 7 to 9, the tag catcher 2 is rotated counterclockwise, so that the coin stopper 5 is moved from the deep groove first recess 2D of the tag catcher 2 to the shallow groove second recess 2E. After the locking projection 5C on the opposite side of the second coin locking portion 5B is suspended, the locking projection 5C of the coin stopper 5 and the tag catcher side locking claw portion 4A of the lock lever 4 are connected to the tag catcher 2. Hanging on the outer peripheral surface (non-recessed portion), the coin a falls off the first coin locking portion 5A and falls into a secondary holding state locked by the second coin locking portion 5B of the coin stopper 5, and is latched. Locking by lever 2A is completed. In addition, the rotation operation part at this time can be removed from the tag catcher 2.

  On the other hand, when the latch lever 2A is unlocked, as shown in FIG. 10, when the tag catcher 2 is rotated counterclockwise via the inserted rotation operation portion, the shallow groove engagement of the tag catcher 2 is achieved. At the same time as the tag catcher side locking claw 4A of the lock lever 4 moves in the order of the recess 2B and the deep groove engagement recess 2C, the locking protrusion 5C on the opposite side of the second coin locking portion 5B of the coin stopper 5 Moves in the order of the second recess 2E having a shallow groove and the first recess 2D having a deep groove, and the coin stopper 5 is rotated clockwise around the support shaft 12 so that the coin a Falls and falls to the coin payout port 3B side.

  As shown in FIG. 3, the coin checker side locking arm piece 4B of the lock lever 4 is locked by the upper protrusion 6A retracted to the rear side of the coin passage 3 of the coin checker 6, and at the same time the stationary pin 12B. The coin shutter 7 of the coin insertion slot 3A is opened, and the tag catcher side engaging claw 4A of the lock lever 4 is engaged with the deep groove engaging recess 2C of the tag catcher 2. By suspending, the state before the coin a is inserted from the coin insertion slot 3A is restored. At this time, the rotation operation unit cannot be removed from the tag catcher 2.
