Abstract:
1. A needle moving device comprising: a performing device which includes an arithmetic processing device connected to the performing device to transmit, to the performing device, a signal for moving the needle to a position; a detector provided in the performing device, the detector being configured to detect whether, after the performing device moves the needle, a needle position after the movement based on the measurement signal from the encoder coincides with the signal transmitted to the performing device by the arithmetic processing device; and a determining portion provided in the arithmetic processing device, the determining portion being configured to determine whether, after the performing device moves the needle, the needle position after the movement based on the measurement signal from the encoder coincides with a designated position that is inputted into the arithmetic processing device from outside, wherein the needle moving device is configured to (i) compare the needle position after the movement with the designated position that is inputted into the arithmetic processing device from outside, and (ii) compare the needle position after the movement with the signal transmitted to the performing device by the arithmetic processing device, so as to determine whether a fault in the movement of the needle to the designated position is caused by the performing device or by the signal provided by the arithmetic processing device to the performing device.
