Products.
The company began in 1951 as a manufacturer of photo processing equipment. The first minilab, the QSS-1 (Quick Service System 1) was introduced by Noritsu in 1976. In 1979 Noritsu released the QSS-2, which for the first time allowed for photo processing, from film development to color printing in just 45 minutes. In 2002 Noritsu introduced the first dry minilab, using Epson's seven color inkjet piezoelectric printing head. It was significantly cheaper than its 
"wet" silver halide counterparts.
Noritsu printer-paper processors (called minilabs) are typically designated a model number beginning with "QSS" followed by a number which increases with each new model. As of August, 2019, the newest Noritsu minilab are the wet silver halide QSS 39 series, introduced in 2018. Noritsu film processors for both C-41 negative and E-6 slide films are typically designated QSF, followed by a letter/number combination. Noritsu made the QSF series of minilab film processors (small film development machines).
Noritsu does not produce consumer photographic products such as film, photographic paper, and chemicals. Because of this, Noritsu works with Eastman Kodak, which produces film, photographic paper and chemicals, but not photofinishing equipment. Some Noritsu models have been re-branded and sold by Kodak as their own equipment. More recently, Noritsu has sold their digital minilabs under their own name, but with Kodak's software (called DLS for Digital Lab System) providing image processing and a user interface, rather than Noritsu's own software. Noritsu sold and supported Kodak's "Picture Maker" kiosks when they were first introduced in the mid-1990s. Noritsu equipment works with different brands paper and chemicals including Kodak, Fujifilm, and Trebla.
Noritsu printer-paper processors are designed for color photographic prints but can be modified to print black and white.
Although Noritsu has typically produced minilabs that utilize traditional silver halide papers and photographic exposure systems, inkjet printing systems in partnership with Epson have been added to the product line since 2003. Noritsu refers to them as "digital dry printers".
In March 2006, Noritsu and Fuji announced a strategic alliance for Noritsu to manufactures all of Fuji's photofinishing hardware. Each company produces its own software.
In 2009, the wide adoption of digital cameras and thus a reduced need for photo processing machines, prompted Noritsu to reorganize into a holding company. 2015, it purchased JLab Audio. In 2016, it sold off its imaging business which manufactured minilabs and is now called Noritsu Precision. Because of this, Noritsu Koki moved its headquarters to Tokyo from Wakayama Prefecture, Japan the year before. Noritsu Precision still uses Noritsu Koki's logo, manufactures minilab printers and is headquartered in Wakayama.
In April 2020, Noritsu bought AlphaTheta Corporation, owner of Pioneer DJ.
