摘要： PROBLEM TO BE SOLVED: To provide a control structure for a shutter capable of being indicated by deciding faults occurring in a driving section and a power source section constituting the shutter or the fact of the necessity for maintenance inspection. SOLUTION: The shutter A is constituted by having a shutter body 1, a mechanism having a hoisting drum 2, the driving section 4 transferring the rotation of a motor 3 to the hoisting drum 2, the power source section 10, an operating section 14, a rotation detection 12 for detecting the rotation of the motor 3, a power source detection 11 for detecting voltage or current of the power source section 10, an operating signal detection for detecting an operating signal, a storage section 15a for storing the rotation of the motor 3 in a normal state and the value of the voltage and current in the power source section 10, a control section 15 transmitting the signal by deciding whether or not the driving section 4, power source section 10 and operating section 14 are normally operated by comparing the information detected by the rotation detection, power source detection and operating signal detection with the rotation and value of the voltage and current stored in the storage section and indicating sections 16 and 20 indicatint whether or not the shutter is normally operated on the basis of the signal transmitted from the control section 15.

摘要： PROBLEM TO BE SOLVED: To wind or lower a shutter with a simple structure and to judge an abnormal situation when a shutter body bites an obstacle. SOLUTION: This shutter A is provided with a mechanism section having the shutter body 1 and a winding drum 2, a drive section 4 having a stepping motor 3 and transmitting the rotation of the stepping motor 3 to the winding drum 2, a power supply section 10, a power supply detecting section 11 detecting a current, an operation section 12 having operation buttons 12a-12c, and a controller 13 stopping the rotation of the stepping motor 3 based on a judgment as a winding limit or a lowering limit when the stepping motor 3 is rotated in one direction and the power supply detecting section 11 detects a current larger than the set current, then rotating the stepping motor 3 by the prescribed angle in the opposite direction to the previous rotating direction, and storing the number of drive pulses for the stepping motor 3 when its rotation of the prescribed angle is stopped between the winding limit and the lowering limit in its memory section 13a.

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.

摘要： PROBLEM TO BE SOLVED: To check a stepping motor whether it is normally rotated or not at present, and whether it is probable to cause step out running or not, and so on, and perform optimum control, by detecting the change of a drive current in the stepping motor, checking a load, and generating a signal. SOLUTION: This control device is constituted by providing a driver part 21 generating a drive signal based on a command pulse given to a stepping motor 1 from a control part 3, a current detection part 22 detecting a drive current, a pulse signal conversion part 23 converting the current detected in the current detection part 21 into a pulse signal, and the control unit 3 previously storing information of a pulse width corresponding to torque of the stepping motor and a control program made to correspond to the pulse width as stored to measure the width of the pulse signal converted in the pulse signal conversion part, comparing it with the stored pulse width, and generating a control signal in accordance with the corresponding pulse width.
