    Abstract: A touch panel driving device, for sequentially performing scanning for selecting a pair of adjacent transmission signal lines and a pair of adjacent reception signal lines on a touch panel, includes a reception circuit configured to receive reception signals whose waveforms are changed by a capacitance change caused by an operation from the pair of reception signal lines of the touch panel and generate a detection value for monitoring a touch panel operation. The reception circuit generates the detection value by comparing levels of the reception signals from the reception signal lines while sequentially switching capacitance values of a measurement capacitance unit connected to one of the reception signal lines. The measurement capacitance unit includes capacitance units each forming a certain capacitance value by parallel connection or series connection of capacitors as a capacitance unit forming one capacitance value used for switching the capacitance value of the measurement capacitance unit.

    Abstract: A print head includes a light guide portion including a light blocking part having a lattice shape, and a plurality of light guide paths defined by the light blocking part, and a light emitting element array in which a plurality of organic EL elements emitting light incident to each light guide path are arranged. In the print head, the plurality of light guide paths of the light guide portion are designed to have an identical width of 30 μm or less, and thus it is possible to reduce exposure unevenness which is one of exposure characteristics.

    Abstract: The parameter setting device has a parameter data input unit and a setting control unit which stores parameter data in an empty channel in the steering signal received from the transmitter and sends it to the transmitter. The parameter setting device and the transmitter are connected, and the parameter data is input to the parameter setting device. The parameter setting device stores the parameter data in the empty channel of the steering signal received from the transmitter and sends it back to the transmitter. The transmitter sends its steering signal to the body to be steered. The parameter data of the specific operation object mounted on the object to be steered can be reliably changed while continuing the operation of the operation object mounted on the object to be steered.

    Abstract: A scanning line driving device drives scanning lines in a display unit including data lines each connected to a plurality of pixels arranged in a column direction and the scanning lines each connected to a plurality of pixels arranged in a row direction, the pixels arranged at respective intersections of the data lines and the scanning lines. The device is configured to sequentially keep each of the scanning lines in a selected state pursuant to a predetermined order and output a scanning line drive signal, which is set to a low level in a high-luminance display drive and to a high level in a low-luminance display drive, to all the scanning lines during a blanking period between a period in which one scanning line is kept selected and a period in which a next scanning line is kept selected.
