ム85に当接させ，両者の係合作用で上記数字輪84を帰零
回動するようになっている。When the integrated display is to be reset to zero, as shown in FIG. 6, the operation transmitting portion 911 of the resetting operation knob 91 pushes and rotates the operating lever 92 which is supported on the resetting shaft 83. . Thus, the return-to-zero engagement portion 871 is brought into contact with the heart cam 85, and the numeral wheel 84 is caused to return to zero by the engagement of the two.

分だけ（第６図においてＨにより示す），積算計の高さ
寸法が大きくなる。However, in the conventional zero-return mechanism, the operating lever is pressed and rotated in the same direction as the operation direction by the operation transmitting part of the zero-return operation knob. Therefore, the height of the integrator is increased by the thickness of the operation transmitting portion (indicated by H in FIG. 6).

計自体の構造が複雑となる。このため，組付け性が悪
く，ひいてはコスト的に不利であった。Further, as described above, while the numeral wheel is driven by the pinion to shift the girder, the numeral wheel is returned to the zero rotation by the engaging action of the return zero engaging portion and the heart cam. Becomes complicated. For this reason, the assemblability was poor, and the cost was disadvantageous.

And a detection switch unit having a rotation return means such as the above. The rotation receiving gear is arranged so as to be able to mesh with a rotation transmission gear interlocked with the integrator main body. is there.
本発明においては，上記操作伝達部のテーパは平面状
に限定されることなく，曲面状であっても良い。In the present invention, the taper of the operation transmitting portion is not limited to a flat surface, but may be a curved surface.
また，上記回転復帰手段としては，ねじりコイルば

接点部を配設することが望ましいが，スイッチ検出では
なくインジケータとしての使用も可能である。The detection switch is turned on by the rotation of the operation shaft.
It is desirable to arrange the wiring pattern and the contact portion so as to be in the state or the OFF state, but it can be used as an indicator instead of a switch detection.

において，スイッチはON状態若しくはOFF状態となって
いる。Since the present invention is configured as described above, the operation receiving portion of the detection switch unit and the rotation transmission gear of the integrator main body normally mesh with each other to rotate the rotation receiving gear. Then, the rotation of the rotation receiving gear causes the operation receiving shaft portion to rotate with the rotation, thereby performing distance detection and the like. In this case, in the detection switch section, the switch is in an ON state or an OFF state.

受け部と同様に作動伝達部も操作伝達部の操作力と略90
度方向の回転力に変換される。Then, when returning the integrator to zero, the depressing operation knob is pressed. As a result, the operation transmitting portion of the return-to-zero operating knob slides on the operation receiving portion of the operating lever, and the operating force of the operation transmitting portion is converted into the rotational force of the operation transmitting portion in a direction substantially 90 degrees. In this case, in the operating lever, since the operation receiving portion and the operation transmitting portion are formed at an acute angle, the operation transmitting portion, like the operation receiving portion, has approximately 90% of the operating force of the operation transmitting portion.
It is converted into a rotational force in the degree direction.

As a result, the engagement between the rotation receiving gear and the rotation transmitting gear is disengaged, and at the same time, the switch in the detection switch unit is turned off or on. As described above, in a free state in which both gears are disengaged, the rotation receiving means such as a torsion coil spring returns the operation receiving shaft portion to the zero point position.
本発明によれば，帰零操作ノブの操作力をこれと略90
度角方向の作動レバーの回転力に変換しているため，積
算計の高さ寸法を小さくすることができる。According to the present invention, the operating force of the zero operation knob is substantially 90
Since the torque is converted into the rotational force of the operating lever in the angle direction, the height of the integrator can be reduced.
また，積算計本体に連動させた回転伝達ギヤに対して
帰零機構の回転受けギヤを噛合させているため，組付け

ヤ50との噛合が外れる。また，これと同時に，上記接点
部380が基板34上の配線パターンから離れる。The operation transmitting part 22 rotated in this manner is the fourth transmitting part.
As shown in the figure, the operation receiving shaft 32 is pressed and moved toward the case 31. As a result, the engagement between the rotation receiving gear 33 and the rotation transmitting gear 50 is released. At the same time, the contact portion 380 separates from the wiring pattern on the substrate 34.

の状態に戻る。そのため，作動受け軸部32が零点位置の
状態に戻る。In a state where the gears 33 and 50 are disengaged in this way, the operation receiving shaft portion 32 becomes rotatable. Therefore, the substrate
Torsion coil spring 35 twisted by rotation of 34
Becomes rotatable, and returns to its original state by its untwisting action. Therefore, the operation receiving shaft part 32 returns to the state of the zero point position.

ね部23により，また検出スイッチ部３はコイルばね36に
よりそれぞれ元の状態に復帰する。When the hand is released from the return-to-zero operating knob 1, the return-to-zero operating knob 1 is returned to its original state by the coil spring 14; Return to.
このように本例によれば，帰零操作ノブ１の操作力を
これと略90度角方向の作動レバー２の回転力に変換する
ことができる。これにより，帰零機構５の高さ寸法を小
さくすることが可能となる。As described above, according to this embodiment, the operating force of the return-to-zero operating knob 1 can be converted into a rotational force of the operating lever 2 in a direction substantially 90 degrees from the operating force. As a result, it is possible to reduce the height of the return-to-zero mechanism 5.
また，板ばね部23により，別途復帰ばねを介装させる
必要がない。これにより，部品点数が少なくなる。Further, the leaf spring portion 23 eliminates the need to separately interpose a return spring. Thereby, the number of parts is reduced.

る。Further, the return-to-zero mechanism 5 can be disposed outside the integrator main body 6 by meshing the rotation transmitting gear 50 and the rotation receiving gear 33. Furthermore, each component can be attached to the bracket 4 and the case 31 with one touch. This improves the ease of assembly.
また，検出スイッチ部３により，距離をスイッチ検出
することができる。Further, the distance can be switch detected by the detection switch unit 3.
それ故，本例によれば，コンパクトで，部品点数が少
なくて，組付け性が良く，かつ，スイッチ機能を備え
た，距離検出器７の帰零機構を得ることができる。Therefore, according to the present embodiment, it is possible to obtain a zero-return mechanism of the distance detector 7 which is compact, has a small number of parts, has good assemblability, and has a switch function.

インジケータとして使用することが可能である。In this example, the contact spring 38 was eliminated, and a display roll was used instead of the substrate 34.
The detection method of the detection switch unit 3 can be changed by providing an opening in the 31 corresponding to the display roll portion. That is, the detection switch unit 3 can be used as an indicator that changes the color of the roll according to the distance, instead of the switch detection as in this example.
