This model of Mini Camera was manufactured in Hong Kong during the 1970s. This is a very low-end model replica of the Arrow Camera previously made in Japan. This model existed in different colors like blue, red, green or black. It uses 17.5mm, 14 x 14mm exposure film. The term "HIT" has come to mean any camera with features similar to the original model -- even if made by another manufacturer. The definition of a HIT camera is generally a camera with a single shutter speed, a fixed-focus lens, using 17.5mm paper-backed film, a body style similar to the original HIT, a fixed aperture, and it produces a 14x14mm image. But there are many cameras that come close to this definition, so what is and isn't a HIT is arguable. These 17.5mm cameras are also sometimes called Mycro (or Micro) or Midget cameras after other common nameplates. The film and format are sometimes called Mycro, as well. Not all 17.5mm cameras are HIT-type cameras, and not all HIT-type cameras use 17.5mm film. Some "HIT" cameras use 16mm film, so it is all quite muddled.

For all cameras of this type named HIT type, there is a book with a very complete CD: The HIT Project 2003 from Mike Parker. In this book, Mike Parker classifies these devices in several families in relation to their characteristics.
