The pockets 6, 13, and 17 are opposed to each other, and the pockets 4 and 12 are opposed to each other in the lower portion, so that the first four pockets 4, 12, and 16 communicate with the upper portion as a whole. One auxiliary pocket portion 21 in which the pocket portion 20 communicates with the auxiliary pockets 6, 13, 17 is formed, and four second pocket portions 22 in which the pockets 4, 12 communicate in the lower portion are formed.

  Then, an operation locking mechanism 24 is provided in each of the first pocket portions 20 located at the upper portion, and a setting spacer supply mechanism 25 is provided in each of the second pocket portions 22 located on the lower side. A reset mechanism 26 is provided.

  The operation locking mechanism 24 contacts the coil spring 30, the base body 31 pressed by the coil spring 30, the block 32 that contacts the base body 31, the setting spacer 33 that contacts the block 32, and the setting spacer 33 from the outer peripheral side. Each of the projecting pins 34 or each of the coil spring 30, the base body 31, the block 32, and the projecting pin 34 is provided.

  The setting spacer supply mechanism 25 includes a coil spring 36, a base body 37 that is pressed by the coil spring 36, and a setting spacer 33 that contacts the base body 37 from the outer peripheral side.

  The cord reset mechanism 26 includes a base body 41 integrally including an operation unit 40 projecting from the outer peripheral side through the opening 5 of the outer peripheral cylinder 1, a first auxiliary block 42 that contacts the base body 41, and the first auxiliary block 42. The second auxiliary block 43 that comes into contact with the coil and a coil spring 44 that presses the second auxiliary block 43 toward the outer peripheral side are provided.

  FIG. 17A is a partial view of the variable lock as viewed from the key insertion hole 15 side. In the vicinity of the end portion of the key insertion hole 15 on the end surface of the inner cylinder 14 located near the outer cylinder 1 is shown. A mark 80 for indicating the position of the key insertion hole 15 is provided, and a mark 81 is also provided on the end surface of the outer cylinder 1 so as to correspond to the mark 80. These marks 80 and 81 are integrally formed and attached at the time of die-casting the member.

  By attaching the marks 80 and 81 as described above, when the marks 80 and 81 are opposed to each other as shown in FIG. 17A, the key insertion hole 15 is recognized as a position during normal locking and unlocking operations. 17B, when the marks 80 and 81 are separated from each other as shown in FIG. 17B, the key insertion hole 15 can be recognized as the position when the code setting is changed. It is possible to easily prevent leaving in the changed state.

  Next, the operation of the variable lock will be described with reference to FIGS. 6 (A), 6 (B), 7 (A), 7 (B), 8 (A), and 8 (B). The description will be given with reference.

  In the state shown in FIG. 6 (A), the variable lock is code-set so as to correspond to the key Ka shown in FIGS. 6 (B) and 7 (A).

  That is, in the upper pocket portion 20, one, two, zero, and one setting spacer 33 are stored from the left [setting code 1201]. Accordingly, only when the key Ka having the shape of the pin pushing portion 39 as shown in FIG. 6B is inserted, the contact surface between the base body 31 and the block 32 is just the outer cylinder 1 in each operation locking mechanism 24. And the intermediate cylinder 8 are positioned in a straight line so as to coincide with the upper contact surface X.

  On the other hand, in the lower pocket portion 22, in the setting spacer supply mechanism 25, the contact surface between the setting spacers 33 and the contact surface between the setting spacer 33 and the base body 37 are just between the outer cylinder 1 and the intermediate cylinder 8. It is located in a straight line so as to match the lower contact surface X.

  In this state, as shown in FIG. 6B, when the operation unit 40 of the reset mechanism 26 is not pushed in, the contact surface between the base body 41 and the first auxiliary block 42 is the upper contact surface X. And the second auxiliary block 43 is positioned on the upper contact surface Y portion of the intermediate cylinder 8 and the inner peripheral cylinder 14. Therefore, in this state, sliding rotation is possible only at the contact surface X, and when the key Ka is rotated, the intermediate cylinder 8 and the inner cylinder 14 are rotated together with the key Ka. Along with this rotation operation, locking and unlocking operations are performed by the action of a lock portion (not shown) integrated with the intermediate cylinder 8.

  In the above, if the key Kb of [setting code 0120] shown in FIGS. 7B and 8A is used, the state shown in FIG. 8B is obtained. In this case, the left two blocks 32 and the rightmost block 32 are both located in the upper contact surface X portion, and the third base body 31 from the left side coincides with the contact surface X portion. As a result, the intermediate cylinder 8 and the inner cylinder 14 do not rotate integrally even when the key Kb is turned, and the locking and unlocking operations cannot be performed. The rotation is not performed only when one of the block 32 or the base body 31 is located at the contact surface X portion.

  Consider the case where the intermediate cylinder 8 is continuously integrated with the outer cylinder 1 and the base body 31 and the block 32 are continuously integrated when the key Kb is used. In this case, the configuration in which the three blocks 32 are located in the contact surface X portion and the configuration in which the one base body 31 is located in the contact surface X portion are not obtained, and the third block 32 from the left side is not obtained. Only the structure in which the part corresponding to is located in the contact surface Y part is obtained. Accordingly, since the portion corresponding to the one block 32 is located in the contact surface Y portion, the inner cylinder 14 is prevented from rotating integrally with the key Kb.

  However, if a key Kc (not shown) having the shape of [setting code 0000] is used under the same conditions as described above, the contact surface Y is set to rotate with the projecting pin 34 in all the operation locking mechanisms 24. Since it matches the contact surface with the spacer 33 or the contact surface between the protruding pin 34 and the corresponding portion of the block 32, the inner cylinder 14 also rotates with the rotation of the key Kc. That is, in the variable lock structure in which the intermediate cylinder 8 is not used and the block 32 is not used, in the case of the lock of [setting code abcd], [setting code efgh] (where e ≦ a, f ≦ b, g ≦ c, h It is possible to lock and unlock even with a key of ≦ d).

In order to eliminate the above inconvenience, in the present embodiment, when the intermediate cylinder 8 is provided and the blocks 32 are respectively mounted and a key having a different setting code is used, the block 24 or the base body 31 is always positioned on the contact surface X. In this way, any key with a different setting code cannot be used. As a result, when m setting spacers 33 are used and the number of the operation locking mechanisms 24 is n, m ⁿ The setting code is obtained.

  Next, the code setting changing operation will be described.

  When changing the code setting of the variable lock, as shown in FIG. 7A, in the state where the key Ka is inserted, the operation unit 40 of the reset mechanism 26 is pushed, and in that state, the key Ka is rotated 180 degrees. In the state where the reset mechanism 26 is pushed in, the lower portion of the base body 41 is positioned on the contact surface X portion, and the contact surface between the first auxiliary block 42 and the second auxiliary block 43 is just aligned with the upper contact surface Y. Then, only sliding rotation on the contact surface Y is possible. Therefore, when the key Ka is rotated, only the inner cylinder 14 is rotated 180 degrees.

  Then, in the rotated state, the key Ka is removed. In the state where the key Ka is pulled out, each protruding pin 34 protrudes into the key insertion hole 15 due to the pressing of each coil spring 36.

  Next, when the key Kb desired to be used is inserted as shown in FIG. 7B, each of the protruding pins 34 is pushed in corresponding to the shape of the pushing portion 39 of the key Kb. Corresponding to the push-in degree of the projecting pin 34, the setting spacer 33 is supplied to the pocket 16 side of the inner peripheral cylinder 14 by leaving 0, 1, 2, 0 from the left side. The key Kb is rotated in the direction opposite to the rotation direction from 6 (B) to FIG. 7 (A). At this time, the reset mechanism 26 is pushed in, so that only the inner cylinder 14 rotates.

  When the reset mechanism 26 is restored after the rotation is completed, the contact surface between the base body 41 of the reset mechanism 26 and the auxiliary block 42 matches the upper contact surface X as shown in FIG.

  Thereby, the setting change of the variable lock is completed, and in this state, the variable lock is changed from the key Ka, and the operation of locking and unlocking with the key Kb becomes possible. That is, in the above code setting changing operation, the [setting code 1201] corresponding to the key Ka is changed to [setting code 0120] corresponding to the key Kb.

  In the variable lock described above, the operation unit 40 of the reset mechanism 26 is pushed in to change the shape of the key that can be locked and unlocked, that is, the key code is changed. As another example of the means for changing the shape of the key, the reset mechanism 26 may not be used. For example, it is different from the range in which the key is inserted into the key insertion hole and rotated during locking and unlocking. It can also be done by rotating to a range.

  The present invention prevents unauthorized modification of a key shape that can be locked and unlocked, that is, a key code. This configuration will be described below with reference to the drawings.

  9A and 9B are diagrams illustrating a first embodiment of a restricting member that prevents unauthorized alteration of the key code. FIG. 9A is a perspective view illustrating a state in which the restricting member is attached to the setting key switch 501, and FIG. It is a perspective view which shows the setting key switch 501 which removed the restriction member, (C) is the front view which looked at the setting key switch 501 of (B) from the direction of the key insertion hole, (D) shows a restriction member.

Configured. The setting key switch 501 is provided with a hole 501b into which the arm portion 503b is inserted.

  A wedge-shaped wedge portion 503c is provided at the tip of the arm portion 503b. When the arm portion 503b is inserted into the hole 501b, the wedge portion 503c does not fit into the hole 501b and is not pulled out, and the setting key switch 501 has a restriction member 503. Can be attached and fixed. Once this restricting member 503 is mounted, it becomes a wedge portion 503c, so that it cannot be removed unless it is damaged.

  In the first embodiment, in order to change the key code of the setting key switch 501, it is necessary to rotate the key inserted into the key insertion hole 501a clockwise. On the other hand, the rotation restricting piece 503a of the restricting member 503 restricts the clockwise rotation of the key. On the other hand, the regulating member 503 does not regulate the off / on switching operation shown in FIG.

  According to the first embodiment, it is possible to prevent the key code from being changed illegally. If the restricting member 503 is forcibly removed, the restricting member 503 is damaged, leaving an improper trace.

  In the above description, the movement range in which the key is inserted into the key insertion hole 501a and rotated is described as the operation range. However, the present invention is not limited to this, and the operation range of the key may be an operation range other than rotation. For example, it may be the depth at which the key is inserted into the key insertion hole 501a, and the restriction member may be any member that restricts these operating ranges.

  Next, Example 2 of the regulating member will be described.

Configured. A wedge-shaped wedge portion 1503c is provided at the tip of the arm portion 1503b, and the configuration for attaching and fixing the regulating member 1503 to the setting key switch 501 is the same as that of the first embodiment. The configuration for restricting the change of the key code of the setting key switch 501 in the restricting member 1503 is the same as that of the first embodiment.

  The restriction member 1503 has a thin portion 1503d, and is easily damaged by the thin portion 1503d when it is likely to be removed from the setting key switch 501 due to an illegal act. For this reason, traces of fraudulent acts remain due to breakage of the regulating member 1503.

  Further, according to the second embodiment, it is possible to prevent the key code from being changed illegally.

  Next, a third embodiment of the restricting member will be described.

  The restricting member 2503 according to the third embodiment is configured to be rotatable by a rotating unit 2503g, and thereby, a person in charge of the store where the slot machine 100 is introduced can change the key code.

  For example, when the slot machine 100 is shipped from the factory, the wedge portion 2503c is not inserted into the hole 501b of the setting key switch 501, and only the wedge portion 2503f is inserted into the hole 501b. In this state, the store clerk who has delivered the slot machine 100 turns the turning portion 2503g so that the rotation restricting piece 2503a does not restrict the rotatable range of the key, and sets the key code of the set key switch 501 to the own store. Change to the key used in. When the key code change is completed, the wedge portion 2503c can be inserted into the hole 501b of the setting key switch 501, and the regulating member 2503 can be attached and fixed to the setting key switch 501. Once the regulating member 2503 is mounted in this manner, the wedge portions 2503c and 2503f are in a state that cannot be removed unless they are damaged.

  According to the third embodiment, it is possible to prevent the key code from being changed illegally. If the restricting member 2503 is forcibly removed, the restricting member 2503 will be damaged, leaving an improper trace.

  Further, if only one wedge part 2503f is fitted in the hole 501b of the setting key switch 501, the restriction by the rotation restricting piece 2503a can be released by turning by the turning part 2503g. The key code can be changed.

  Next, a fifth embodiment of the restricting member will be described.

  13A and 13B are diagrams showing a fifth embodiment of a regulating member that prevents unauthorized alteration of a key code. FIG. 13A is a perspective view showing a setting key switch, and FIG. It is a perspective view which shows a regulation member in the state which carried out, (C) is a side view of a regulation member, (D) is a perspective view which shows the state which mounted | wore the setting key switch with the regulation member.

  In the above-described first, second, third, and fourth embodiments, the restriction member for the one that needs to rotate the key inserted into the key insertion hole 501a clockwise to change the key code of the setting key switch 501 has been described.

In this case, the change of the key code can be restricted by providing the rotation restricting piece 5503a of the restricting member 5503 at the upper right position of the key insertion hole 501a. According to the rotation restricting piece 5503a, the key inserted into the key insertion hole 501a can be rotated 90 degrees counterclockwise.

  FIG. 14D shows an example in which the setting key switch 2501 needs to rotate the key inserted into the key insertion hole 2501a counterclockwise in order to change the key code. In this case, the change of the key code can be restricted by providing the rotation restricting piece 6503a of the restricting member 6503 at the lower right position of the key insertion hole 2501a. According to this rotation restricting piece 6503a, the key inserted into the key insertion hole 2501a can be rotated 90 degrees clockwise.

Unlocking and locking the front door 102 can be performed by turning the inserted key clockwise.

  In such a lock, a configuration is known in which the key code can be changed by rotating the key inserted into the key insertion hole, for example, by a half turn (180 degrees). Therefore, in the following, a restricting member that restricts the key inserted into the key insertion hole so that it can be rotated in both the clockwise and counterclockwise directions, but cannot be rotated in the half circumference, will be described.

As a function of the lock 3501, the lock 3501 rotates in both the clockwise and counterclockwise directions. An example of what needs to be done. In this case, the rotation restricting piece 8503a of the restricting member 8503 is provided on the right side of the key insertion hole 3501a, and can be rotated clockwise and counterclockwise while restricting half-turn rotation so that the key code cannot be changed. ing.

As a function of the lock 3501, the lock 3501 rotates in both the clockwise and counterclockwise directions. An example of what needs to be done. In this case, the rotation restricting piece 9503a of the restricting member 9503 is provided on the left side of the key insertion hole 3501a so that clockwise and counterclockwise rotation is possible, but half rotation is restricted so that the key code cannot be changed. ing.
