摘要:
A needle bar stopper is provided in a sewing machine having a main shaft and a needle bar which moves vertically upon reception of a driving force from the main shaft. The needle bar stopper comprises a transmission prohibiting unit, including a needle bar stopping solenoid, which prohibits transmission of the driving force from the main shaft to the needle bar and a braking unit, including a needle bar stopping solenoid, which applies a braking force to the needle bar when transmission of the driving force is prohibited by the transmission prohibiting unit. The needle bar stopper can stop the needle bar reliably by use of the braking unit.
摘要:
A sewing machine including a needle bar for holding a sewing needle which conveys a sewing thread; a shaft member to which the needle bar is connected; a needle-bar drive motor which reciprocates the needle bar via the shaft member; a loop catcher which cooperates with the sewing needle to catch a loop of the sewing thread conveyed by the sewing needle; a catcher drive motor which rotates the loop catcher; an asynchronism detector which detects a first asynchronous state in which an amount of asynchronism between the needle bar and the loop catcher is greater than a first reference value and/or a second asynchronous state in which it is expected that the amount of asynchronism will be greater than a second reference value; and a holding device which holds, when the asynchronism detector detects the first and/or second asynchronous state, the needle bar and/or the loop catcher, at a holding position where the sewing needle and the loop catcher do not collide with each other.
摘要:
An embroidery machine having a spindle, a sewing machine motor driving the spindle, and a thread cutting device including a thread cutting motor and a thread cutting mechanism provided with a movable blade driven by the thread cutting motor. The thread cutting motor is provided independently of the sewing machine motor and is driven so that the movable blade is moved in synchronism with the spindle. The movable blade is movable between a maximum pivot positioned farthest from a stationary blade and a stand-by position close to the stationary blade.

A sewing device including a head portion for mounting a needle; a support frame; and a bed unit supported on the frame and switchable between a usage position in confrontation with the head portion and a retracted position retracted away from the head portion compared with the usage position.
摘要:
A sewing machine capable of cutting only a needle thread without cutting a bobbin thread during the middle of stitching operation for changing the needle thread with another needle thread. A thread cutting motor is driven independent of a sewing machine motor. A rotary hook control unit is provided for controlling rotation of a rotary hook as well as driving mode of the thread cutting motor in relation to a rotation of a spindle. A thread cutting mechanism including a movable blade pivotably driven by the thread cutting motor is provided between the rotary hook and a throat plate. If the movable blade is moved from its maximum pivot position to a stand-by position, both needle thread and bobbin thread are cut at the final number of stitch. If the movable blade is moved from a needle thread cutting position to the stand-by position, only the needle thread can be cut.
摘要:
A sewing machine including a needle bar having a sewing needle, a spindle for driving the needle bar, a bed portion movable selectively to a using position or a retracted position, and a rotary hook housed in the bed portion. A stitch is formed by the cooperation of the sewing needle and the rotary hook. A rotary hook drive motor is provided in the bed portion for driving the rotary hook. A sensor is provided for detecting a position of the bed portion. The needle bar and the spindle is selectively disconnected from each other. If the bed portion is out of the using position, and this out position is detected by the sensor, the needle bar is released from the spindle for stopping the sewing needle. Further, in this case, the rotation of the rotary hook drive motor is also stopped.
摘要:
An embroidery machine having a plurality of beds and corresponding heads. In each of the heads, a plurality of needle bars supporting needles and thread take up levers are provided. Each bed contains a rotary hook drive motor provided independent of a sewing machine motor which drives a spindle extending through the heads. The rotary hook drive motor is driven in synchronization with the spindle for performing embroidery stitching, but is driven independently of the spindle at a specific rotation angle range thereof based on number of stitching. In each bed, a conventional needle thread holding mechanism is dispensed with. By controlling rotation of the rotary hook drive motor, a residual end part of the needle thread has a sufficient length capable of avoiding disengagement of the residual end part from an eyelet of the needle at a thread cutting operation.
摘要:
A visually-distracted-driving detection device that can detect visually distracted driving with high accuracy. The visually-distracted-driving detection device includes a visually-distracted-driving determination unit that determines that a driver is visually distracted if the direction in which the driver is looking is greater than or equal to a predetermined angle with respect to the front of the driver; and a prohibition unit that, if it is specified that the present position of the vehicle as specified by a present-position specifying unit is within a first predetermined distance from an intersection, prohibits a process that is performed in cases where it is determined that the driver is visually distracted.

An automotive instrument specifying unit of an automotive instrument operating device specifies a group of automotive instruments on the basis of the direction of gaze of an occupant detected by a gaze direction detector, and specifies one automotive instrument from among the specified group of automotive instruments on the basis of the up/down direction selected by up/down direction selecting unit when the up/down direction selecting unit has been operated in a state in which the group of automotive instruments has been specified.

In a sight line vector detecting system comprising: an infrared light source for illuminating either an eye or a face; a camera for photographing either the eye or the face; and a computer for processing photographed image data of said camera so as to calculate a sight line vector, the computer includes an image processing unit for detecting the true luminance point and the center of the pupil from the photographed image data; and a calculating unit for calculating the sight line vector; and the image processing unit performs such a processing operation that the image processing unit determines a luminance point capable of satisfying a predetermined requirement as the true luminance point among luminance points having the pupils at near places, calculates a center of the pupils, and further, calculates a center of a cornea ball.
