We are applying our inkjet, machine vision, image processing, and other technologies in diverse initiatives. They include the Japanese government-supported Funding Program for World-Leading Innovative R&D on Science and Technology and joint R&D with universities and independent administrative corporations. We are reinforcing relationships with venture enterprises to accelerate the creation of new businesses.

Open innovation case study

Inspecting bridges with drones

We are undertaking research under the auspices of the Infrastructure, Maintenance, Renovation and Management Technologies initiative of the Cross-Ministerial Strategic Innovation Promotion Program of the Japanese Cabinet’s Council for Science, Technology and Innovation. The New Energy and Industrial Technology Development Organization is supervising that initiative. The theme is R&D into drone systems for acoustic and proximity visual inspections of bridges. Associate Professor Kazunori Ohno of Tohoku University is heading this research.

3D bioprinters

We are participating in a national project led by the Japan Agency for Medical Research and Development, which is undertaking joint research with Osaka University.

Inspecting roads with stereo cameras

We developed technologies as part of the Road Surface Condition Monitoring Verification Testing Consortium. Its members are the Ministry of Land, Infrastructure and Transport, Akita Prefecture and Semboku, a city in that prefecture, and the Ricoh Institute of Information and Communication Technology.

In March 2016, we established a fund to foster tech ventures that drive progress in next-generation industries.
Through this fund, we aim to contribute to industry development by financing tech ventures and by supporting start-up and accelerating the commercialization of technologies.

R&D investments and intellectual property initiatives

The Ricoh Group consistently earmarks 5% to 6% of consolidated sales for R&D to ensure a steady stream of innovation. In the fiscal year ended March 31, 2017, R&D expenses reached ¥114.3 billion, or about 5.6% of sales. Of this amount, 10.7%, or ¥12.3 billion, went into basic research.
Intellectual property , the fruit of our R&D efforts, is vital to our competitiveness. We therefore encourage efforts that yield valuable intellectual property and seek to acquire and use intellectual property that protects and grows our businesses. We have deployed business and technological strategies to reinforcing core businesses, globalizing by cultivating operations in emerging nations, and launching new businesses to expand our domains.
We have deployed strategies to expand our domains, reinforcing core businesses, globalizing by cultivating operations in emerging nations, and launching new businesses. We accordingly continue to secure patents in Japan and abroad. As a result, the number of registered patents overseas has exceeded the number in Japan since the fiscal year ended March 31, 2015. We are conducting a review of maintained patent rights by assessing future market and business conditions and determining whether to abandon any unnecessary patent rights.

Initiatives in Intellectual Property

Changes in R&D investment

Changes in R&D investment *In the fiscal year ended March 31, 2017, R&D investments relating to the camera business were included in the Other segment after being part of Imaging and Solutions.
If R&D investments based on the approach for the fiscal year ended March 31, 2016 were applied in the fiscal year ended March 31, 2017, they would have been ¥3.4 billion.

Transforming workplaces through knowledge creation

In pushing forward with EMPOWERING DIGITAL WORKPLACES, we are developing technologies to support ongoing knowledge creation by working people.

Supporting knowledge creation by organically linking inputting, processing, and outputting

We defined three necessary steps that we organically link and evaluate to supply smart systems and solutions that support knowledge creation.

  • Capture: Collect a range of information with optimal devices
  • Analytics: Examine and process collected information and convert it into intelligence
  • Visualize: Optimally supply the results of processing to systems and people

Knowledge Creation Support

Knowledge Creation Support

● Road surface inspection system

Special vehicles are commonly used to maintain road infrastructure. We developed a camera system that can be mounted on standard monitor vehicles to evaluate road surfaces. Multiple stereo cameras can measure the rate of cracks, the depth of ruts, and flatness in a single pass. The system decodes images with a model obtained through machine learning, reducing man-hours. The Maintenance Control Index, a comprehensive benchmark for making repair decisions, is calculated based on findings, and provides support for writing up inspection records. The results can be mapped to visualize the road surface conditions.

● Public infrastructure inspection system

The aging of bridges and other structures has become a social problem worldwide. The need to perform inspections in high places poses considerable risks. Another issue in recent years has been shortages of inspectors.
We developed a spherical shell drone equipped with a camera that can maintain appropriate distances from target structures and can safely capture macro shots of bridge floor slabs and supporting sections. The photos are automatically reconstructed into 3D panoramic images. The system links images with bridge position information to help with preparing records according to inspection procedures. This saves a lot of labor and contributes to report consistency.

●Localization service

We provide services that optimize the use of precious time at medical institutions by pinpointing the locations of people and objects in real time, reducing inconvenience, wasted effort, and inconsistency.
Radio frequency identifier (RFID) tags on patients, medical staff, and medical equipment transmit information to in-hospital receivers. The acquired positioning data goes to our location information server on the cloud and is processed, with each location being displayed on in-hospital maps.
This setup eliminates considerable time otherwise wasted seeking people and objects, helping to streamline work efficiency.
