Further, auxiliary claws 12d and 13d are formed on the cam portion side of the first mountain tumbler 12 and the second mountain tumbler 13, respectively. When a card key that does not match is inserted, it enters the determination unit 3d together with the claws 12c, 13c, 15c, and restrains the slide of the internal unit 4. This prohibits inadvertent locking / unlocking.

  On the other hand, the number 0 tumbler 14 is a tumbler having no claw as described above. There is no entry into the determination unit 3d or disengagement. The 0th tumbler 14 is a tumbler that does not act on the discriminating portion 3d, and does not know the position where the 1st mountain tumbler 12 or the 2nd mountain tumbler 13 is provided.

  An auxiliary cam portion 15 d is provided on the cam portion 15 b side of the conversion tumbler 15. The auxiliary cam portion 15d is formed to engage and disengage while making cam contact with the slide rail portion 3e. When engaging with the rail portion 3e, the internal unit 4 is allowed to slide in that state, but the internal unit 4 resists the force of pulling out and prohibits pulling out. The auxiliary cam portion 15d is disengaged from the rail portion 3e, so that the internal unit 4 can be slid and removed. In addition to the tumblers 12 to 15 described above, a dummy tumbler (not shown) that functions as a so-called dummy is also provided as appropriate.

  The arrangement of the tumblers 12 to 15 is appropriately combined, laminated on the tumbler shaft 11, and incorporated in the inner case 7 integrally with the leaf spring 10, thereby forming the inner unit 4. When this internal unit 4 is incorporated in the external case 3, a card key device having the structure shown in FIG. 7A can be assembled. The orientation of the tumblers 12 to 15 is alternately arranged as shown in FIG. 7C, for example, by taking the No. 1 mountain tumbler 12 as an example.

  Thus, the state of each tumbler incorporated in the card key device is specifically shown in FIG. 8 (a) for the No. 1 mountain tumbler 12, and FIG. 9 (a) for the No. 2 mountain tumbler 13. FIG. 10 shows a cross-sectional view of FIG. 10 and the conversion tumbler 15 is shown in FIG. 11B.

  That is, the tumblers 12 to 15 are urged by the spring force in the free state of the leaf spring 10, and the claws 12c, 13c, and 15c enter the determination unit 3d. On the other hand, the cam portions 12b, 13b, 15b face the card key insertion path (insertion path) 16.

<Card key and conversion card key>
The card key 1 and the conversion card key 5 are formed by molding a transparent synthetic resin material. The card key 1 has a planar shape shown in FIG. 12 (a), and a tapered portion 1a having an inclination angle of, for example, about 20 ° is formed at the tip edge so as to make cam contact with the cam portions 12b to 15b of each tumbler. Is done. On the upper surface, a key groove 1b having a cross-sectional mountain shape that engages with the cam portion 12b of the first mountain tumbler 12 and a key groove 1c having a cross-sectional mountain shape that engages with the cam portion 13b of the second mountain tumbler 13 are engraved. The The depth of the keyway 1c for the second mountain is set larger than that of the keyway 1b for the first mountain. The conversion card key 5 has a planar shape shown in FIG. 12B, and key grooves 1b and 1c having the same shape as the card key 1 are arranged on the upper surface thereof. The only difference from the card key 1 is that a key groove 1d having a mountain-shaped cross section that is engaged with the cam portion 15b of the conversion tumbler 15 is formed.

<Bridge member>
As shown in FIGS. 5 (f) and 7 (a), the eaves member 9 is formed of a gate-shaped portion 9a and an L-shaped portion 9b extending from the portal-shaped portion 9a. The portal portion 9a is provided so as to embrace both sides of the box portion 7a of the inner case 7. The L-shaped portion 9b is provided so that the guide groove 3j of the outer case 3 can be moved in and out (see FIG. 3A). Thus, when the card keys 1 and 15 are in the locking position as shown in FIG. 7A, the L-shaped portion 9b protrudes from the outer case 3 and locks a lock (not shown). On the contrary, when the card keys 1 and 15 are slid to the unlocking position on the left side, the L-shaped portion 9b is immersed in the outer case 3 and unlocks the lock. When the internal unit 4 is taken out from the external case 3 and replaced with another internal unit 4 at the unlocking position using the conversion card key 5, the bag device 9 is left behind in the external case 3.

Until then, the nail | claw 12c which has entered the determination part 3d is released. The auxiliary claw 12d does not enter the determination unit 3d. As a result, the inner case 7 is slidable integrally with the card key 1 and can be locked and unlocked.

  If the keyways do not match, as shown in FIG. 8C, the claw 12c remains in the determination unit 3d and is in a non-slidable state. Although not shown, when the cam portion 12b rides on the flat surface of the card key 1 that is not a keyway, the auxiliary claw 12d enters the determination portion 3d and makes sliding impossible.

  When the card key 1 is inserted in the state of FIG. 9A, the cam portion 13b rides on the key groove 1c for the second mountain of the card key 1 as shown in FIG. Similarly to the case of the first mountain tumbler 12, the claw 13c and the auxiliary claw 13d of the tumbler 13 are released from the determination unit 3d. As a result, the internal unit 4 that has been in a restrained state can be slid, that is, can be locked and unlocked.

  As shown in FIG. 5C, when the user rides on a key groove different from the key groove 1c, the auxiliary claw 13d enters the determination unit 3d. Thereby, the slide of the internal unit 4, that is, the locking / unlocking operation is restrained.

  As for the 0th tumbler 14, as shown in FIG. 10, the 0th tumbler 14 rides on the flat surface of the card key regardless of whether the card key 1 for locking / unlocking or the card key 5 for conversion is inserted. Move. However, since the 0th tumbler 14 does not have a claw, it does not enter the determination unit 3d. For this reason, the slide of the internal unit 4 is not restrained from beginning to end.

  As described above, when the card key device 1 is inserted into the card key device, the internal unit 4 can be slid with respect to the outer case 3 together with the card key 1. As a result, the bag device 9 can be locked and unlocked.

  Next, for the conversion tumbler 15, as shown in FIG. 11B, the cam portion 15 b of the tumbler 15 rides on the flat surface of the conversion card key 5. The conversion tumbler 15 swings in the clockwise direction around the tumbler shaft 11 against the urging force of the leaf spring 10. The auxiliary cam portion 15d comes into contact with the slide rail portion 3e. Thus, the internal unit 4 is restrained from being pulled out to the left, but the auxiliary cam portion 15d can slide along the slide rail portion 3e, so that the internal unit 4 can be slid.

  When the conversion card key 5 is inserted into the locking position shown in FIG. 11 (a) and used, when the normal card key 1 is inserted as shown in FIG. 11 (c), it is shown in FIG. 11 (b). Thus, the cam portion 15b rides on the key groove 1d of the conversion mountain. Since the auxiliary cam portion 15d is released from the contact with the slide rail portion 3e, the internal unit 4 can be removed. The internal unit 4 cannot be taken out at the locked position.

  When the conversion card key 5 is slid from the locked position to the unlocked position together with the internal unit 4 in this state, the scissor device 9 is unlocked and the internal unit 4 remains externally with the conversion card key 5 inserted. The case 3 can be taken out. As a result, the external case 3 taken out can be carried and exchanged with another new internal unit 4 to be stored and set in the external case 3 for use.

  When a new internal unit 4 is set, the conversion card key 5 is slid from the unlocked position to the locked position together with the internal unit 4 while the conversion card key 5 is inserted. If only the conversion card key 5 is pulled out after being slid to the locking position, the bag device 9 can be locked. Thereafter, the card key device can be locked and unlocked again using the normal card key 1.

  According to the present embodiment, the locking / unlocking operation is performed by sliding the card key 1, unlike the conventional embodiment in which the key blank is rotated and used. For this reason, it is possible to differentiate from products of other companies, and it is possible to obtain operational performance overflowing with a smart sense in terms of use. Further, if there is a shallow installation space in the card key insertion direction, the card key device can be easily attached. Further, by using the conversion card key 5, the card unit can be used by exchanging the internal unit 4, and a convenient card key device can be obtained while ensuring security. Although a large number of tumblers are used, since the swing of all the tumblers 12 to 15 is controlled by a single leaf spring 10, the number of parts can be greatly reduced, and the card key device with a simple structure. Can be realized. Furthermore, the design can be improved by making the card keys 1 and 5 transparent. Moreover, since the conversion card key 5 can be manufactured using the same card as the locking / unlocking card key 1, a cost-effective card key device can be obtained.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea thereof.

  For example, in the above embodiment, two tumbler shafts 11 are provided, but the number of tumblers does not have to be alternately arranged with one. Further, the conversion tumbler 15 may be provided at any position in the sliding direction.

  In the above description, the hook member 9 is slid and locked / unlocked before the lock. However, as the hook member, for example, either the outer case 3 or the inner unit 4 is interposed between the outer case 3 and the inner unit 4. A rack and pinion mechanism having a rack tooth on one side and a pinion gear on the other side may be used to convert the slide of the internal unit 4 into a rotational motion.

  Moreover, although the card keys 1 and 5 were formed using the synthetic resin material, you may use a metal. The leaf spring 10 is pivotally supported on the box portion 7 a of the inner case 7 using the tumbler shaft 11. However, the leaf spring 10 may be attached to the box portion 7 a without using the tumbler shaft 11.

  In the above description, a single plate spring 10 is used as the spring member. However, a plate spring, a coil spring, or the like that swings and biases the tumbler may be provided for each tumbler.

  INDUSTRIAL APPLICABILITY The present invention is used for a card key device as a locking / unlocking device employed in various devices such as office desks, wagons, lockers, cabinets and cupboards.
