後退が阻止される。First, the unlocking numerals 47 are aligned on the dial stop line 15 of the housing 1, and then the movable hook 3 is engaged with the fixed side hook by rotating the operating mechanism 2 by a photographing operation. At this time, the end of the actuating shaft 41 has an unlocking recess 23 of the collar 22.
While protruding from a and fitting into the lock recess 23, each of the on-axis projections 42 corresponds to a projection engagement groove 46 (FIG. 4).
By rotating each dial 45 arbitrarily in this state,
The protrusion engagement grooves 46 are displaced from the protrusions 42 to prevent the operation shaft 41 from retracting.

従って、操作機構２の操作軸21は、作動軸41がカラー22
のロック凹部23に係合状態にあるため、軸回転せず、ロ
ック状態が保たれる。Therefore, in the operating shaft 21 of the operating mechanism 2, the operating shaft 41 has the collar 22.
Since it is engaged with the lock recess 23, the shaft does not rotate and the locked state is maintained.

の設定を完了する。When changing the unlocking number 47, when inserting the projecting rod through the small hole 12 of the housing 1 and pressurizing the pressing member 51, each bush
44 compresses and slides the spring 50, and the engagement between the ridge 48 and the groove 49 between the bush 44 and the dial 45 is released. At this time, each dial 45 is turned to position a new numeral 47 on the dial stop line 15 of the housing 1, and then the pressing member is pressed.
Release the pressure on 51. This allows each bush 44 to
Re-engage into dial 45 with 50 force and unlock new number 47
Complete the settings.

整列させて設定を行う。In the embodiment shown in FIGS. 5 to 7, when the movable hook 3 is disengaged from the fixed side hook, the outer cylinder of the operating mechanism 2 is removed.
By the 24 and the cam 55, the operating shaft 41 is located on the dial 45 side, and the bushes 44 are slid in the opposite direction to the operating shaft 41, and the ridges 48 and the concave grooves 49 between the dials 45 and the bushes 44 are located. Is disengaged, while each protrusion 42 on the actuating shaft engages with the protrusion engagement groove 46 of each bush 44 (FIG. 5). As a result, each dial 45 is in a state of free rotation with respect to each bush 44, and the unlocking numbers 47 are aligned on the line 15 of the housing 1 for setting.

置をずらせることにより、ロック状態が保たれる。At the time of locking, similarly to the above-described example, the movable hook 3 is engaged with the fixed side hook by rotating the operation photograph 21, and the recess 23 of the outer cylinder 24 of the operation mechanism 2 is attached to the operating shaft 41. Correspondingly, the tips engage. On the other hand, the higher part of the cam 55
56b corresponds to the slide bush 53, and each bush 44 is engaged in the dial 45. By the reverse sliding of the bush 44 and the operating shaft 41, the respective projecting pieces 42 on the shaft are disengaged from the projecting piece engaging grooves 46 of each bushing 44 (FIG. 7). At this time, the locked state is maintained by rotating each dial 45 to shift the position of each projection engaging groove 46 with respect to each projection 42.

がサイドバー26を解放する。In this embodiment, if the user forgets the unlocked number 47, or if he / she accidentally locks it without looking at the number, in order to unlock it, a suitable key (not shown) is placed on the operation camera 21. When inserting into the inner cylinder 25 through the opened keyhole, use the disc tumbler 27
Releases sidebar 26.

Since the movable hook 3 is axially fixed to the inner cylinder 25, the lock can be released. After that, the door is opened, the colored display 52 of the bush 44 is seen through the see-through window 13 on the back side of the housing 1 while turning the dial 45, the unlocked number 47 is confirmed, and the forgotten number is processed.

施例と同様であるため、その説明を省略する。In the embodiment shown in FIGS. 11 to 13, the movable hook 3 is of a sliding type, and is projected and retracted from the housing 1 by the pin 28 of the actuating shaft 20, and the connection with the dial lock 4 is the same as in the above-mentioned respective embodiments. Therefore, the description thereof is omitted.

The mechanism and the mechanism can be configured together, and the practical effect is remarkable by simplifying the configuration.
