An easy-to-use battery life display that operates the display board from the standby position to the operating position in the same way as when the battery voltage drops to a predetermined value even when the battery voltage is not in use, i.e., the display board does not remain in the standby position in such a state. The purpose is to provide equipment.

回動吸引レバーとからなっている。Conventionally, this type of battery life display device sends a display drive signal for only a few seconds at a predetermined voltage value that is slightly higher than the lowest voltage value that can normally drive a clock movement. A check time period having a substantially constant time interval shown in the functional ice crystal clock is set, and the number of output pulses from any predetermined stage of the frequency dividing circuit is added and counted to the first time period of the check time period. During the time period 2, the number of output pulses of the predetermined stage is subtracted and counted while the voltage applied to the part including the oscillation circuit and the frequency divider circuit is decreased by a certain amount, and when the difference between the added value and the subtracted value is more than a certain amount, the battery is activated. An electronic circuit that issues an end-of-life notice signal, a magnetic pole plate containing a permanent magnet, and is wound around the magnetic pole plate and inputs the display drive signal, and the magnetic force generated at this time has a polarity that cancels out the magnetic force of the permanent magnet. A display drive coil, a rotating suction lever having a magnetic body attracted to the magnetic pole plate on one end and a locking part on the other end for holding the display plate in the standby position, which has a standby position and an operating position. It consists of

ことにより回動吸引レバーの吸着が解かれて回動し、従
って表示板の係止も解かれ表示板は待機位置から作動位
置へ落下し電池交換を指示するのである。In such a configuration, until the voltage of the battery drops to a predetermined voltage value, a rotary suction lever attracted to the magnetic pole plate hangs the display board and maintains the standby position, and the voltage drops to a predetermined voltage value. When the magnetic force decreases, a signal is input from the electronic circuit to the display drive coil, and the magnetic force generated here cancels the magnetic force of the permanent magnet, causing the rotary attraction lever to release its attraction and rotate, thus also locking the display board. When released, the display plate falls from the standby position to the operating position, instructing battery replacement.

合関係に房り始め回動吸引レバーが磁極板に吸着した状
態では表示板は完全に係止され待機位置に保たれる。After replacing the battery, if you push up the display board in the operating position, a part of the display board will displace the rotary suction lever to the side where it will attract the magnetic pole plate, and will also engage with the locking part of the rotary suction lever. When the rotary suction lever is attracted to the magnetic pole plate, the display plate is completely locked and kept in the standby position.

く従って使用者に時計が故障であるかの誤解を与える欠
点があった。The battery life is displayed in this way, but the signal is input to the display drive coil only when the battery is at a predetermined voltage value, and in order to minimize battery consumption, it can only be secured for a few seconds. Even if the battery is removed, if you push up the display board, the rotating suction lever will be attracted to the magnetic pole plate, so the display board will naturally remain in the standby position even though the clock is not running. There was a drawback that the display plate was not in the operating position, giving the user a misunderstanding that the watch was malfunctioning.

またこの時計を使用するにあたり表示板の動作を確認す
るには電池に接続される電子回路の端子間に所定の電圧

用者では極めて困難である欠点をも有していた。Additionally, when using this watch, the only way to check the operation of the display board is to apply a predetermined voltage between the terminals of the electronic circuit connected to the battery, which is extremely difficult for normal users. It also had drawbacks.

本考案はかかる欠点を除去したもので以下図面に従って
説明する。The present invention eliminates these drawbacks and will be described below with reference to the drawings.

うにしである。A rotary suction lever 13 is rotatably supported in holes 11 and 12 provided corresponding to a bearing plate 10 attached to the base 7a and the electronic circuit section 4. The end face 7 of the base part 7a and the opposing part 7c of the magnetic pole plate 7
(A suction plate 14 that can be attached to L7e to form a magnetic short circuit state is attached. The other side has a locking part 13d that has a relationship with the display plate 5 through a bent part 13c. If this is taken as a reference, the weight of the side having the suction plate 14 will be larger.

It has a detection part 17a that comes into contact when the battery 3 is inserted and held normally, and a pressing part 17b that can come into contact with the tip 13b of the rotating suction lever 13 at the other end, so that the detection part 17a and the battery 3 come into contact. When in contact, the tip portion 13b and the pressing portion 17
b is a shape with a slight void, and the energizing spring 1
8, it is always energized clockwise.

。Here, the biasing force of the biasing spring 18 is applied to the magnetic pole plate 7 when the battery 3 is removed, the battery detection lever 17 rotates clockwise, and the pressing part 17b presses the tip 13b of the rotating suction lever 13. The size is set so that the adsorption of the plate 14 can be released.

第３図は作動機構部の正面図を示す。FIG. 3 shows a front view of the operating mechanism.

３ｄから解除され作動位置へ落下して電池交換の指示を
する。In this state, the battery voltage gradually decreases, and when it reaches a predetermined voltage value, a signal is input from the electronic circuit 4 to the display drive coil 9, and the magnetic force generated thereby cancels the magnetic force of the magnetic pole plate 7. Since the attraction of the suction plate 14 is released, the rotary suction lever 13 rotates clockwise according to its own weight imbalance, and the display plate 5 is moved to the locking portion 1.
It is released from 3d and falls to the operating position to instruct battery replacement.

電池寿命表示機能を果す。When the display plate 5 is pushed up after battery replacement, the pressing end 5c presses the base 13a of the rotary suction lever 13 and rotates the lever 13 counterclockwise.When pushed up enough, the suction plate 14 becomes the magnetic pole plate. 7, and the engaging end portion 5b is locked to the locking portion 13d, so that even if you release your hand from the display board 5, the display board 4
maintains a suspended, so-called standby position and functions in the same manner as below to perform the battery life display function.

圧して吸着を解除するのである。Next, the battery detection lever 17, which was not available in the conventional example, keeps the detection part 17a in elastic contact with the battery 3 when the battery 3 is inserted and held in a predetermined position, and when the battery 3 is removed. It is rotated clockwise by the biasing spring 18,
When the suction plate 14 attached to the rotary suction lever 13 is attracted to the magnetic pole plate 7, the pressing portion 17b presses the tip portion 13b to release the suction.

Since it is pushed back by the detection lever 17, the suction is released and it is not kept in the standby position.
