の紛失によるトラブルが発生し易く、またキーの不正使
用による盗難事故も多発している。<Prior Art> Conventionally, for example, a locker for renting is provided with a lock that opens and closes with a unique key for each locker. In the case of this type of lock, since the locker user carries the key around, troubles due to the loss of the key are likely to occur, and thefts due to unauthorized use of the key also frequently occur.

〈発明が解決しようとする問題点〉 これを解消するのに、キーを必要としない符号錠を用い

号が固定的に決められているため、その解錠符号が他人
に知られると、もはや錠として機能を喪失し、その他人
により不正に解錠される虞がある。<Problems to be Solved by the Invention> In order to solve this, there is a method of using a code lock that does not require a key, but in the conventional code lock, the unlock code is fixedly determined for each lock. Therefore, if the unlock code is known to another person, it may lose its function as a lock and may be unlocked illegally by another person.

解錠符号は、錠内部のメカ構造を調整すれば変更するこ
とも可能であるが、その種の作業には熟練を要し、ロッ
カーなどの使用者が変わる毎にその種の作業を行うこと
は管理者にとって甚だ煩雑である。It is possible to change the unlock code by adjusting the mechanical structure inside the lock, but it requires skill to perform such work, and such work must be performed every time the user such as the locker changes. Is very complicated for the administrator.

特に不特定多数人が使用するゴルフ場などの貸ロッカー

更に先立ち各ダイヤルをフリー状態にするための特別な
操作が必要である。In particular, in the case of a rental locker such as a golf course used by an unspecified large number of users, since the user changes every day, it is necessary to change the unlock code each time. Recently, a crescent lock has been proposed in which the user can mechanically change the unlock code (Act. No. 53-103493), but such a lock is not suitable for use as a locker and the unlock code Special operation is required to set each dial to the free state before setting or changing.

また近年、キーボード操作により任意の解錠符号を設定
できる電気式の符号錠も提案されているが、この種の符
号錠の場合、電源の供給が必要であって設備が大掛かり
となり、設備費用が高価となる問題がある。In addition, in recent years, an electric code lock that can set an arbitrary unlock code by keyboard operation has been proposed, but in the case of this type of code lock, it is necessary to supply a power source, and the equipment becomes large-scale, and the equipment cost is low. There is a problem of becoming expensive.

以上の実情から、電源を必要とせず、しかも解錠状態下
でダイヤル調整だけで機構的に解錠符号の設定や変更が
可能な錠の出現が望まれているが、現在そのようなもの
は存在しない。From the above circumstances, the emergence of a lock that does not require a power supply and is capable of mechanically setting and changing the unlock code only by adjusting the dial under the unlocked state is desired. not exist.

ック状態が保たれる。At this time, an arbitrary numeral 36 used for unlocking is aligned on the dial stop line 15 of the housing 1. Next, by rotating the locking mechanism 2 by a photographing operation, the cam plate 22 engages with the fixed-side receiving portion and is locked. At this time, the operating shaft 30 comes out of the unlocking recessed portion of the outer tubular collar portion 27 and engages with the locking recessed portion 28, and the bush 33 causes the operating piece 4 to move.
0 is located at the high position 29b of the cam 29, and each dial 3
4 and the convex groove 37 and the concave groove 38 are engaged with each other, and the protrusion 31 on the actuating shaft 30 is released from the protrusion engaging groove 35, and the unlocked number is set. When the push button 54 of the zero return mechanism 5 is pressed in this state, the operating arm 55 rotates the corresponding eccentric cam 53, and the dials 34 are simultaneously rotated via the transmission gear 52 and the gear 50. Three
Align the unlocked number “0” of 4 on line 15 of housing 1. As a result, the protrusions 31 and the protrusion engagement grooves 35 are displaced from each other, so that the movement of the actuating shaft 30 is prevented and the locked state is maintained.

等を処理する。In the lock of this embodiment, if the numeral 36 used for unlocking is forgotten, or if it is accidentally locked without looking at the numeral, a suitable key (not shown) can be used to unlock it. When inserting into the inner cylinder 20 through the keyhole opened in the operation photograph 24, the disk tumbler 26 operates the side bar 25 to cut off the space between the outer cylinder 23 and the inner cylinder 20, and the inner cylinder 20 can rotate independently. . In this state, by rotating the key in the same direction as the operation shooting 24, leaving the outer cylinder 23,
The inner cylinder 20 pivots. Since the cam plate 22 is axially fixed to the inner cylinder 20, the lock can be unlocked. After that, open the door and turn the dial 34 to rotate the housing 1
A guide pin is inserted through the guide hole 13 on the back side of the, the pin hole of the bush 33 is searched for, the unlocked number 36 is confirmed, and the forgotten number is processed.
