The electronic device and precision products operations segment includes the microdevice business, watch business, and FA business.

Microdevices Business

Aiming for lower energy consumption, compact size, higher precision, and greater reliability

By fusing the QMEMS technology that was developed through expertise in creating crystal devices toghther with semiconductor technology, Epson is working to improve the performance of every electronic device product. Epson is also creating systematized and modularized microsystem products that combine Epson's crystal device, semiconductor and software technologies. By doing so, we can offer products and propose solutions that help support customers in a variety of fields, including products such as PDAs, DSC/DVCs, AV equipment, automotive electronics, healthcare, and sensor networks.

Timing devices

Business printer
crystal oscillator

Timing devices provide timing signals for transmitting data at the right time and speed and provide continuous synchronizing signals.

Sensing devices

Business printer
6-axis sensor

Sensing devices transform physical quantities such as angular velocity, temperature, or pressure, into electronic signals.

Semiconductor devices

Business printer
EPD controller

Epson's semiconductor devices apply our three low-power technologies: low current leakage process, electricity efficient algorithms, and low power analog IP.

Micro systems

Sensing platforms
Inertial Measurement Unit

System units combine Epson's crystal device and semiconductor devices with our software technology to create new systems and modules.

Ever since releasing the world's first quartz wristwatch to great acclaim, Epson has taken its place among the world's leading companies. The technology behind that product was the starting point for Epson's precision and microprocessing technologies. Today the development and production of Epson's line of mostly high-end and mid-range wrist watches is supported by three major technologies-Spring Drive, solar radio wave and kinetics.

Factory automation

Advanced controller technologies revolutionize the factory

Epson's robotic technology started with the development of robots to assemble wristwatches. That know-how has carried over to the present day in the form of extreme precision, high speed and total reliability, and continues to evolve into "saving " technologies (space-saving, energy-saving, and time-seving) and advanced controller technologies.


Epson handlers have made possible high throughput and stable operation at a world-ranking level, and are contributing to the ongoing growth of the semiconductor industry.

Production process reform through industrial-use inkjet technology
