A sheet-feeding device for separating sheets stored in a sheet storage unit by blowing air heated by a heater toward the sheets includes a controller which detects an abnormality when a heater temperature does not reach a first predetermined temperature within a predetermined time. The controller continues to control the heater temperature but stops determining whether or not the heater temperature is increased to the first predetermined temperature within the predetermined time when it is detected that the sheet storage unit is in an open state.

A method and a device for testing an array substrate for a liquid crystal display that allow time for testing to be reduced are provided. An array substrate is divided into two test blocks, and two scanning signal lines in total, one from each of the test blocks, are selected and tested at a time, so that the addresses of possible defective pixels are specified. Then, the array substrate is divided into three test blocks, and three scanning signal lines in total, one from each of the test blocks, are selected and re-tested at a time, so that the addresses of possible defective pixels are specified. Then, the address of a pixel common between the first testing and re-testing is specified as a defective address.

A control board includes a main-board and a plurality of sub-boards which control loads. The sub-boards each include a providing unit which provides a board type ID, a read unit which reads an installation location ID, and a transmission unit which transmits the board type ID and the installation location ID to the main-board. The main-board includes a communication control unit, a configuration information acquisition unit which acquires configuration information expressed by a combination of the board type ID and the installation location ID, an analysis unit which analyzes the configuration information, and a control unit which controls the sub-unit on the basis of information analyzed by the analysis unit.
摘要:
A copy machine comprises a fluorescent lamp inverter circuit for supplying a voltage necessary to light on a fluorescent lamp for exposing an original, an inverter control circuit for outputting an inverter drive signal of a first frequency to control the fluorescent lamp inverter circuit, a light modulation control circuit for outputting a light modulation drive signal of a second frequency to control a current flowing in the fluorescent lamp, and a synchronization circuit for synchronizing the inverter drive signal and the light modulation drive signal with each other by using a clock division circuit and a phase-locked loop (PLL) circuit. Thus, unevenness in exposing of the original is eliminated, thereby improving image quality.
