Abstract: As a weighing device which can not only make water and dust less likely to reach the sensor unit, but also simply discharge water having reached that position if any, and which further can improve the maintenance workability of water-washing of the sensor unit, an electronic balance includes a weighing pan, a load cell that measures a load of a measuring object placed on the weighing pan, and a scale main body case that supports the load cell. The load cell is disposed outside and over the scale main body case, a cylindrical transparent cover that covers the whole side face of the load cell is integrally provided for the weighing pan, and the lower end of the transparent cover is disposed with a clearance over an upper face of the scale main body case.

Abstract: A network printer includes a communication unit for carrying out transmission/reception of data via a network and a recording unit for printing out received print data. The communication unit includes a priority level determination unit, when second print data is accepted during reception of first print data, for determining priority between the first and second print data, and a first persistent connection control unit for executing a persistent connection control that prohibits a transmission source of print data determined as lower priority data from transmitting the print data while a session is being connected with the transmission source, and for permitting a transmission source of print data determined as higher priority data to transmit the print data.

Abstract: An image forming device includes a receiving unit, a generating unit, a forming unit, a detecting unit and an error information generating unit. The receiving unit receives print data and device information relating to a remote device from the remote device. The generating unit generates image data from the print data received by the receiving unit. The forming unit forms an image based on the image data generated by the generating unit onto a recording medium. The detecting unit detects a generation of a print error based on the print data received by the receiving unit. When the detecting unit detects the generation of the print error, the error information generating unit generates error information including the received device information and information relating to the detected print error.
