Clothes Changing Camera/ Dress Up Camera (着せ替えカメラ, Kisekae kamera?)
A camera that uses a picture of clothing instead of film, and changes the clothes of the person in the viewfinder to the clothing in the picture. It may also be used with no picture or an incomplete picture, with embarrassing results. The story about Doraemon’s fourth-dimensional dustbin shows that the damaged camera will make the person naked (ie. when Shizuka used the damaged camera on Nobita, he turned naked). The camera is often used in the long stories and movies, where the gang must disguise themselves in unfamiliar places to avoid attracting undue attention, or to provide with a second change of clothes such as bathing suits.
Translation konyaku/ Translation Jelly (ほんやくコンニャク, hon’yaku-konnyaku?)
A piece of konjac jelly which enables a person to understand and speak any known language in the universe. The effect begins after the person ingests the jelly, but the duration of the effect is unknown. While the ones Doraemon uses are usually unflavored, in the story Nobita’s Birth of Japan (のび太の日本誕生?), he used one labeled to be miso flavored, suggesting the existence of various flavors, which are more expensive.
Small light is a lamp similar to a flashlight that will shrink objects and people to minuscule sizes. Its opposite is the big light (ビッグライト?), which enlarges objects and people. Another tool that is used in a similar capacity is the Gulliver Tunnel, which causes a person to grow or shrink depending on which entrance he takes; however, its ratio of shrinking and enlarging is fixed. Unlike the Gulliver Tunnel, however, the effect of the Small light is not permanent and will wear off after a period of time has passed (seen in the series to be anywhere from a few hours in the comics to a few days in the movie Doraemon: Nobita’s Little Star Wars)
Another frequently used gadget, the time cloth has the ability to advance or reverse time depending on which of its two different colored sides are used. When an object is wrapped around with one face outward, the flow of time reverses, causing the object to become newer. When wrapped around the other way, time moves forward, causing the object to become older. It was first used by Nobita to turn old appliances to new appliances to make money, but its uses extend to many other things, such as converting an object back to its starting material, repairing broken machinery, aging or de-aging people, and restoring millions-of-years old fossils. When picked up, of course, the holder does not age, which means the cloth is only activated upon covering an item, hence it can floating over objects with no user and still change the time of objects.
