向に回転する場合について説明する。The state of the opening in FIG. 2 is the same as that shown in FIG.
When the input rotation shaft 1 rotates a little from the state shown in Figure 2, the weight 4 falls as much as possible to a stable state due to gravity and reaches the second position.
The state shown in Figure C is reached. When moving from the state shown in FIG. 2 (opening) to the state shown in FIG. send a signal. After the state shown in FIG. 2C, the input rotating shaft 1 continues to rotate.
The state shown in FIG. 2A is reached again, and the above-mentioned operations are repeated. Next, a case where the input rotating shaft 1 rotates in a clockwise direction opposite to the arrow shown in FIG. 1 will be described.

リードスイッチ７の近傍を通過するため、次のような欠
点を生じていた。In FIG. 3A, when the input rotation shaft 1 starts rotating clockwise, the push rod 101 engages with the protrusion 301 from the opposite direction to the state in FIG. introduce.
Therefore, the weight 4 is pushed up to the state shown in Figure 3. At this time, the magnet 6 gradually passes near the reed switch 7 at a rotational speed equal to the rotational speed of the input rotating shaft 1, thereby closing the reed switch 7 and transmitting a pulse signal. Third
The state changes rapidly from the state shown in the figure to the state shown in FIG. 3C due to the gravitational action of the weight 4. Thereafter, the above-mentioned operation is repeated. In this conventional pulse transmitter, the input rotating shaft 1
During forward rotation (counterclockwise direction), a regular pulse signal is transmitted every time the input rotation shaft 1 rotates, but when input rotation shaft 1 rotates clockwise (counterclockwise direction), the magnet 6 causes the reed switch 7 to rotate at a speed equal to the input rotation speed. Because it passes through nearby areas, it has the following drawbacks:
（ａ）リードスイッチ７の閉成している時間が一定しな
い。（ｂ）リードスイッチ１が閉成状態から開放状態に
切換わる直前て長時間停滞すると、リードスイッチ７の
接触抵抗が大きく且つ接触抵抗の変動が激しくて接点の

くなり、パルス数の計数の誤りを生じる原因となる。こ
の発明は上記のような従来のものの欠点を除去するため
になされたものである。(a) The time that the reed switch 7 is closed is not constant. (b) If the reed switch 1 remains stagnant for a long time just before switching from the closed state to the open state, the contact resistance of the reed switch 7 is large and the contact resistance fluctuates rapidly, causing welding of the contacts. (c) The number of times the reed switch 7 is opened and closed increases, causing an error in counting the number of pulses. This invention was made in order to eliminate the drawbacks of the conventional ones as described above.

端面５０１ｂとの間に、所定距離が設けられている。In FIG. 6A, when the input rotating shaft 1 starts to rotate clockwise, the push rod 101 engages with the protrusion 301 from the opposite direction to the state in FIG. to communicate. When the rotating plate 3 rotates clockwise, the engaging portion 401 of the weight 4 engages with the other end surface 501b of the engaging protrusion 501 of the driving plate 5, rotating the driving plate 5 to the state shown in FIG. become. In this case, since a predetermined distance is provided between the one end surface 501a and the other end surface 501b of the engaging protrusion 501, the magnet 6
has not passed near the reed switch 7 yet. 6th
When the input rotating shaft 1 rotates a little from the state shown in the figure, the weight 4 falls as much as possible to a stable state due to gravity, resulting in the state shown in FIG. 6C. When moving from the state shown in FIG. 6 to the state shown in FIG. send a signal. After the state shown in FIG. 6C, the input rotating shaft 1 continues to rotate, and the state shown in FIG. 6B is reached again, and the above-described operation is repeated. The present invention is configured as described above, and the engaging protrusion 50 engages with the engaging portion 401 of the weight 4 when the input rotating shaft 1 rotates forward.
A predetermined distance is provided between one end surface 501a of the engagement protrusion 501 and the other end surface 501b of the engagement protrusion 501 with which the engagement portion 401 of the weight 4 engages when the input rotation shaft 1 rotates in reverse.
従つて磁石６が入力回転軸１の回転速度と等しい回転速

Therefore, the reed switch 7 can accurately transmit a pulse every time the input rotating shaft 1 rotates. As described above, according to the present invention, it is possible to accurately transmit a pulse every time the input rotating shaft is rotated.
