Abstract: An optical communication equipment performs optical communication between a first apparatus and a second apparatus. The optical communication equipment includes a monitoring section configured to monitor a light amount during optical communication, and a control device configured to output predetermined information when the light amount is less than a first threshold value and shut off communication between the first and second apparatuses when the light amount is less than a second threshold value lower than the first threshold value.

Abstract: A trace memory that stores trace logs of multiple feeders set on a feeder setting table of a component mounter is provided in the feeder setting table, and while the component mounter is operating, trace logs of each feeder are output from the control sections of the multiple feeders on the feeder setting table to the feeder setting table, and are stored by a communication control section of the feeder setting table in the trace memory linked to identification information of each feeder. By this, it is possible to save trace logs from multiple feeders on the feeder setting table all together in a shared trace memory, such that it is not necessary to load trace memory on each feeder, thereby meeting requirements of compact feeders and lower costs.

Abstract: A power supply control device for controlling a consumption current supplied from a power supply device to a tape feeder loaded on a component supply device, the component supply device being exchangeably loaded with multiple of the tape feeders, the power supply control device including: a consumption current acquiring section configured to acquire the consumption current corresponding to a state of the multiple tape feeders; a total consumption current calculating section configured to calculate a total consumption current that is a total of each of the consumption currents of the multiple tape feeders; and an operation controlling section configured to control the specified operation of the multiple tape feeders within a range in which the total consumption current does not exceed an output current capacity of the power supply device.

Abstract: There is provided a component mounting machine in which when detecting a lowermost end position of a component sucked by a suction nozzle, a lower edge position of the component is detected at predetermined intervals from a left side and a right side using the lowermost end position as a reference. The component mounting machine derives an approximate straight line obtained by approximating multiple lower edge positions detected from the side having a larger detection number and the lowermost end position and an angle of the approximate straight line is detected as the suction angle of the component. Accordingly, the component mounting machine can appropriately detect the suction angle of the component with a simple process and correctly determine the suction posture of the component.

Abstract: A power supply control device that controls consumption currents that are supplied from power supply devices in a component supply device in which multiple tape feeders are replaceably installed, the device including: a total consumption current measuring section that obtains, based on measurement, a total consumption current by adding actual consumption currents which are supplied to a plurality of tape feeders; and an overcurrent protection section that causes a specific tape feeder, which is in an operation state, to transition to a stop state or a standby state, in a case of an overcurrent state where the total consumption current exceeds an output current capacity of the power supply device. Accordingly, even though the overcurrent state occurs during setup changing work in which the multiple tape feeders can operate, the overcurrent state is rapidly canceled, and thus a protecting function is improved.

Abstract: Electronic component supply device of the present invention includes multiple feeders each having an individual control section configured to operate by use of operation software to control a tape feeding mechanism, a host control section capable of holding update software configured to be replaced with at least part of the operation software, and multiple information transmission sections connected between the host control section and the individual control sections of the multiple feeders so as to transmit information and configured to transmit the update software from the host control section to the individual control sections independently of one another. According to this configuration, the multiple information transmission sections can transmit the update software to the different feeders in parallel in terms of time, whereby the updating time can be shortened significantly compared with a case where update software is transmitted sequentially to multiple feeders.

Abstract: A component mounting machine is provided with a suction nozzle including a nozzle suction surface, a camera acquiring nozzle imaged data of a tip end of the suction nozzle, and a control device determining the quality of a nozzle suction surface.

Abstract: A mounter is provided with a head unit with a suction nozzle capable of picking up an electronic component that transfers the electronic component to a specified position, an imaging device that images the pickup orientation of the electronic component, a component data acquiring device that acquires the size of the electronic component, an image processing section that image processes the captured image, and an image processing pattern selecting section. The image processing pattern selecting section, based on the size of the electronic component, is able to select one image processing range and one image processing accuracy from multiple predetermined image processing ranges and multiple predetermined printing accuracies, and, as the size of the electronic component acquired from the component data acquiring section becomes smaller, selects a smaller image processing range and a more accurate image processing accuracy from the multiple image processing ranges and multiple image processing accuracies.
