摘要： PROBLEM TO BE SOLVED: To miniaturize a power transmission for winding particularly at a part without space such as a shutter or a thick stage curtain. SOLUTION: A gear train composed of gears 6a-6d including a moving gear 5 is arranged between an input shaft 1 formed of the output shaft of a motor, and an output shaft 2. A fixed gear 10 is arranged in a specified position near the gear train. A lever 8b is driven by a three-position drive source 8a constituting a driving member 8, and a movable shaft fitted with the moving gear 5 is fixed to the lever 8b. When the moving gear 5 is moved into a first position, the moving gear 5 is meshed with the gear 6a of the input shaft 1 to transmit the rotation of the input shaft 1 to the output shaft 2. When moved into a second position, the moving gear 5 is meshed with the fixed gear 10 to restrain the output shaft out of rotation. When moved into a third position, the moving gear 5 is meshed with neither the input shaft 1 nor the fixed gear 10, so that the output shaft 2 is held in a freely rotatable state.

摘要： PROBLEM TO BE SOLVED: To alleviate labor when a shutter is opened and to realize opening of the shutter in a short period of time when the shutter is opened/closed by manual operation. SOLUTION: A drum 16 on which a shutter body 11 constructed by arranging a plurality of slats in parallel, is wound, and a pulley 15 which is driven by a cord 2 which is to be manually operated, are installed on a shaft pipe 13 which is a fixed shaft. A clutch member 17 is interposed between a transmission member 19 which is combined with the internal periphery of the drum 16 in one body, and the pulley 15, and as the pulley 15 is rotated, a ball 17a of the clutch member 17 is protruded or withdrawn with respect to the transmission member 19 side, whereby the ball engages with or disengages from a projection. A spring 20 is arranged between the drum 16 and the shaft pipe 13, and when the drum 16 winds down the shutter body 11, energy is stored at the spring 20. On the other hand, when the engagement at the clutch member 17 is cancelled, the spring 20 is released, whereby the drum 16 is rotated in a winding-up direction.

摘要： PROBLEM TO BE SOLVED: To set the stop position of a hoisted body without using a sensor directly detecting the hoisted body in a hoisting device of a shutter and a thick curtain or the like. SOLUTION: A rotary encoder 6 is fitted to the motor 4a of a drive member 4 for generating a signal in a response to the rotation of a cylinder for winding a shutter body 1. The pulse signal generated from the rotary encoder 6 is calculated by the arithmetic section 7a of a control member 7. A setting switch 8d generating an instruction signal is provided on an operation panel 8. When the shutter body 1 reaches a winding limit position Su, an instruction signal is generated from the setting switch 8d, and the calculated value of the pulse signal is stored in a primary memory section 7b. A winding switch 8a or an unwinding switch 8b are operated to wind or unwind the shutter body 1, and a stop signal is sent to a motor 4b from the control member 7 when the pulse number from the rotary encoder 6 coincides with the value stored in the primary memory section 7b.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for detecting obstacles for an electric shutter by detecting the electric current value or the rotational frequency of a mortar provided in the electric shutter. SOLUTION: In a method of detecting obstacles in an electric shutter, the electric current value or the rotational frequency of mortar 4b in the winding-up process of a shutter body 1 from the lowest winding point Sb to the highest winding point Sa and also the winding-down process from highest winding point Sa to the lowest winding point Sb are respectively measured in advance in condition that there are no obstacles both in the shutter body 1 and a winding drum 2. A winding-up control value and a winding-down control value are determined in accordance with the measured values. The apparatus recognizes the existence of obstacles in case that the measured value of the electric current value or the rotational frequency of mortar 4b in a practical operation surpasses the predetermined winding-up control value or the winding-down control value.

摘要： PROBLEM TO BE SOLVED: To assure stable stop precision even when a shutter body is repeatedly wound or rewound. SOLUTION: In a shutter A, the shutter body 1 is wound or rewound by speed-reducing rotation of a motor 4b by a reduction gear 4c having a gear train to rotate a winding drum 2. When the shutter body 1 reaches a speed reduction start point Sad close to a winding upper limit position Sa, or when the shutter body reaches a speed reduction start point Sbd close to a winding lower limit position Sb, rotation speed of the motor 4b is reduced, and when the shutter body 1 reaches the winding upper limit position Sd or the winding lower limit position Sb, it is stopped.
