摘要： PROBLEM TO BE SOLVED: To correctly provide prescribed information even where pulses of disturbing light exist. SOLUTION: A prescribed object (work to be sewn) is irradiated by a light emitting means 3 which emits pulse light, radiation light irradiating the object is received by light receiving means 4a, 4b, and prescribed information (edge part information) is obtained by an information obtaining means (edge part information obtaining means) 19 based on received light quantity received by the light receiving means 4a, 4b. In the meanwhile, as pulses of disturbing light are detected by a disturbing light pulse detection means 70 in a pulse light emitting timing of the light emitting means 3, the light emitting means 3 again is set to emit pulse light before the next pulse light emitting timing by a light emission control means 55, and the information obtaining means 19 obtains prescribed information based on received light quantity received by the light receiving means 4a, 4b at the time of above second pulse emission, while prescribed information when the pulses of disturbing light are detected is ignored.

摘要： PURPOSE:To surely remove the thread remaining on a bobbin so as to improve the reliability on a residual thread remover by judging that the device has failed in pull out of thread when it has detects the nonrevolution of bobbin during removal of residual thread, and executing the pull of the thread again, in case of removing the residual thread on a bobbin. CONSTITUTION:If a bobbin case 4 is set in a residual thread removal zone, according to a carrier 3, a control means 50 is operated. And, an air cylinder 12 is advanced by turning on a solenoid valve 12a, and also when the end of thread wound on a bobbin 10 is caught between a thread remover 7 and a receiving shaft 9 after a lapse of specified time, a winding means 60 is rotated in the opposite direction to that at winding of thread by operating a motor 37 so as to wind the thread wound on the bobbin 10 on a spindle 8. At this time, if photointerruptor 11 detects the nonrevolution of the bobbin 10, it performs the catching and winding operation of the winding means 60 again. Then, after a lapse of a specified time, the motor 37 is stopped, and also the air cylinder 12 is retreated.

摘要： PURPOSE:To improve operation efficiency remarkably, by a method wherein the title device is composed so that stacking with the drive of a sewing machine or without the drive thereof is alternately done. CONSTITUTION:After cloth is set on a presetter 56, presetter presser feet 8 are lowered and the cloth is depressed, when a start switch 10 is turned on, and after that, the presetter 6 is moved forward. When a forward switch for the presetter 6 is turned on, conveying part presser feet 4 are lowered and the cloth is depressed with a conveying part 3. After the presetter presser feed 8 are raised, the presetter 6 is moved backward and the end part of the cloth is dropped by the operation of a cloth-dropping blower. In case of a pair mode, a sewing flag is reset or set by the decision of the sewing flag, and after that, on the basis of the decision of the sewing flag, stacking with the drive of a sewing machine is done, or only the stacking without the drive thereof is done. In case of no pair mode, the sewing flag is not reset or not set, and on the basis of the decision of the sewing flag, the same movement is done.

摘要： PROBLEM TO BE SOLVED: To provide a method and device for measuring an object wherein the object to be measured such as cream solder can be three-dimensionally measured with sure in a low-cost configuration. SOLUTION: A laser beam from a laser light source 1 is projected to an object 11 to be measured through a line generator lens 5 as a line beam. A projector unit 7 is moved at a constant speed by a linear actuator 8, and when it comes to a light shielding position, the laser light source is turned on to shield the light, measuring the height of the object. For 2-dimension measurement of the object, a line beam is projected with the laser light source turned on so that the object is irradiated with the line beam for acquiring an image. With this configuration, a 2-dimension form can be imaged with a single line beam scanning, resulting in a shorter image analysis time.

摘要： PURPOSE:To detect the cloth end position with high accuracy even if the lower cloth has a step part by making a solar cell for measuring the upper cloth and the lower cloth end positions, and a light emitting element for the upper cloth supported with an anti-insertion side of a separating plate as a supporting point so as to be turnable integrally in the vertical direction. CONSTITUTION:In the case of sewing the lower cloth 3 having a step part 3a onto the upper cloth 2, solar cells 1C, 1D for measuring a lower cloth end position, a light emitting LED panel 3A for the upper cloth and solar cells 1A, 1B for measuring an upper cloth end position are turned upwards integrally with a shaft 13 as a supporting point, therefore, the lower cloth 3 is inserted without a hindrance between a light emitting LED panel 3B for the upper cloth and the solar cells 1C, 1D. In this case, a relative position relation of the panel 3B and the solar cells 1C, 1D is varied sine the panel 3B is fixed to a throat plate side 11 side. This turning angle is detected by a solar cell 10C for discriminating the lower cloth step part, and the lower cloth end position corresponding to an output voltage of the solar cells 1C, 1D is corrected by a control means.

摘要： PURPOSE:To prevent a sewing machine from halting due to an error treatment and increase productivity by designing it so that a counter measuring the number of feeding motions reacted with no-button outputs button feed error when it has reached a specified value and stops feeding of buttons. CONSTITUTION:When it is detected that there is no button by a button presence- judgement means 16, the error is immediately treated and a re-feed means 18 of buttons is actuated without halt of the machine and this actuated numbers is counted by the no-button counter 17, and a button feeder 12 is driven through the button re-feeder 18 and a button feed designator 13 by a plurality of times, subsequently 10 times, for instance, until buttons are fed hereafter. When the buttons are not fed even after 10 times of the feeding operation of buttons, only at the time, the machine is stopped by a stopping means 19 of the machine, and when buttons are fed until the no-button counter 17 counts 10 times, the counter is cleared to continue the fitting work of buttons.
