Printers

Reliable technologies that create a sense of security and raise productivity—Printers

Greater sense of security based on proven technological strengths and constant enhancements in productivity

Our inkjet print heads are a core component of industrial inkjet printers that print by spraying micro ink droplets directly onto the targeted object. These print heads are contributing to improvements in productivity and quality in the advertising billboard industry as well as the construction materials and textile industries. Our thermal printer mechanism, which enables printing by applying a heating element to thermal paper, is compact and outstanding in terms of quiet operation and low maintenance. Thanks to these features, this printer mechanism is being used in an extensive range of areas close to our lives, including POS registers, payment settlement terminals, and medical and measuring devices.

Compactness, low power consumption and high functionality―Electronic devices

Realizing compactness, low power consumption and high functionality

Our electronic devices, which originate from the development of quartz watches, play a key role in a broad range of fields that include smart phones, digital home electronic appliances, automobiles and industrial equipment. Our CMOS ICs and quartz crystals feature compact low-voltage drives, low power consumption and high precision, all of which contribute to the realization of more compact and highly functional devices with longer operating times. Our CMOS ICs are widely used for vehicles which require stable operation under harsh conditions, and their capabilities are highly acclaimed. Meanwhile, our ICs for quartz crystal modules command the world's largest share. Our battery technologies cultivated during the development and manufacturing processes for watch components and our magnetic and high-functional metallic products are currently contributing to the miniaturization and high functionality of electronic devices.

Basic Strategies

The Electronic Devices business will concentrate the allocation of management resources on core businesses and raise earnings power. We also have carried out a business reorganization that includes selling the large-sized printer business and establishing a joint venture company in the semiconductor (IC) business. In the future, we will invest in core businesses and cooperate with external partners to achieve further growth.
