    • PURPOSE:To obtain a compact measuring tape device for both manual and electrical drive by containing an electric motor and a power transmission mechanism in a handle for manual winding of a measuring tape and adding a clutch mechanism. CONSTITUTION:A clutch mechanism for changing over of winding of a measuring tape to either manual or electrical drive is provided, and for example, an electric motor is contained in a grip for manual winding handle, and a power transmission mechanism in a handle respectively. For instance, at the time of operating the device by the electrical drive, the rotation of the motor contained in the grip 4 of the handle is transmitted to the winding drum of a measuring tape 14 by a reduction gear contained in a handle 9 via the clutch. On the other hand, when a manual- electric changeover slider 11 is changed over to the manual side, the above-mentioned clutch is disengaged, and the handle part is fixed to the above-mentioned drum, whereby manual winding is made possible. Thereby, the compact measuring tape device that permits smooth changeover of the electric and manual drive is obtained.
    • 目的:通过在手柄中卷绕卷尺并附加离合器机构,在手柄中装入电动马达和动力传递机构,以获得手动和电力驱动的紧凑型测量带装置。 本发明提供一种用于将卷带卷绕到手动或电动驱动器上的离合器机构,例如,电动马达包含在手柄上的手柄和手柄中的动力传递机构。 例如,在通过电驱动来操作设备时,容纳在手柄的手柄4中的电动机的旋转通过包含在手柄9中的减速齿轮经由操作杆14被传递到卷尺14的卷绕鼓 离合器。 另一方面,当手动电动切换滑块11切换到手动侧时,上述离合器分离,把手部固定在上述滚筒上,从而可以进行手动上弦。 由此,能够实现电动和手动驱动的平滑切换的小型卷带装置。
