A switch device () includes: a cap () including, on a top surface (), a first region () and a second region () corresponding to a position where an internal light () is disposed and being thinner than the first region (); and a switch () to which the cap () is mounted.

Switch device, electronic apparatus, and electronic musical instrument

There is provided an ink jet recording apparatus including an ink jet head and a drive circuit. The ink jet head forms an image on a recording medium in response to a drive signal applied to multiple piezoelectric elements. The drive signal causes multiple pressure chambers corresponding to the multiple piezoelectric elements to expand or to contract in volume and causes ink in the multiple pressure chambers to be discharged from multiple nozzles. The drive circuit generates a drive signal for discharging multiple liquid droplets to one pixel for combining the multiple liquid droplets together and applies the drive signal to each of the multiple piezoelectric elements of the ink jet head. The drive signal includes multiple discharge pulses which make velocities of tips of respective liquid columns substantially same after a predetermined time from starting of ink discharge from the nozzles.

Ink jet recording apparatus and ink jet recording method

A liquid droplet ejection apparatus including a headin which a plurality of ink chambersare aligned in one or both of an X direction and a Y direction, liquid droplets are ejected from nozzles, and printing is carried out in a print region of a recording medium based on print data, wherein the ink contains a dispersion medium and solid particles having higher specific gravity than that of the dispersion medium, and the liquid droplet ejection apparatus includes a flushing device that performs a flushing operation when the headis present in a non-print region in such a manner that an amount of liquid droplets ejected from the nozzleplaced at an end portion in an alignment direction becomes larger than an amount of liquid droplets ejected from the nozzleplaced in a central portion in the alignment direction.

Liquid droplet injection apparatus and method for recovering nozzle of liquid droplet injection apparatus

An inkjet head includes pressure chambers arranged in 2 or more rows and a common ink chamber connected to all the pressure chambers, wherein each of the pressure chambers includes a damper member inside of the common ink chamber of the inkjet head for commonly supplying an ink from the common ink chamber via an ink inlet which faces the common ink chamber, and the shortest distance between the damper member and the ink inlet is made shorter than the distance between ink inlets in adjacent rows of pressure chambers.
