Embodiment Construction

[0031] 1 is a plan view showing a substrate 40 on which a control circuit (signal output device) 20 and an electrostatic actuator (electromechanical conversion element) 30 according to the first embodiment of the present invention are mounted. The block diagram of FIG. 2 shows the connection between the control circuit 20 and the electrostatic actuator 30.

[0032] As shown in FIG. 3, the control circuit 20 includes a control unit 21, a timing waveform generating device 22, an output port switching device 23, a boosting device (not shown), and a switching device (not shown). The timing waveform generating device 22 and the output port switching device 23 constitute a signal output device.

[0033] The control unit 21 includes a register 21a. The register 21a includes registers 21b-21d. The control unit 21 outputs waveform time register data D1, waveform data register data D2, and output port exchange data D3.

[0034] The waveform time register data D1 and the waveform data regist...

Abstract

The signal output unit comprises a timing waveform generator outputting signals from a plurality of output ends, respectively, and an output port exchange unit having output ports for outputting signals from the timing waveform generator and exchanging a corresponding relationship of the output ends and the output ports based on a predetermined exchange rule.

Description

[0001] Cross-references to related applications [0002] The present invention is based on the prior Japanese patent application JP2004-107337 filed on March 31, 2004, and claims priority, the entire content of which is incorporated herein by reference. Technical field [0003] The present invention relates to a signal output device that outputs a waveform signal for controlling a control target device, and more particularly to a signal output device. When the signal output device is connected to a control target device mounted on a mounting substrate, it can Reduce the component installation area for mounting the substrate. Background technique [0004] A signal output device that outputs a waveform output signal for driving the electrostatic actuator is known (for example, see Japanese Patent Application Publication JP08-140367). [0005] In the wiring pattern design of the substrate connecting the signal output device for outputting multiple waveform output signals and the cont...
