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.
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.
One of Doraemon’s most commonly used gadgets is the dokodemo door, a door which allows travel to anywhere by simply going through the door. In an early story, the door is able to travel to the end of the universe, but in later chapters, the door is said to only be able to travel a maximum distance of 100,000 light years and cannot access other dimensions. Another limitation of the door is that it can only safely connect two known locations in its mapping computer, which also has a limited range of information based on Time as shown in the movie “Nobita’s Dinosaur.”
One of the main modes of transportation for the various characters is the take-copter, which combines the words taketombo (bamboo dragonfly, the Japanese name for the bamboo-copter), and part of the word herikoput which means helicopter. The take-copter was also called the heri-tombo in early stories. The device is a propeller attached to a tiny suction cup which can be attached to enable flight. Ever since the first few Doraemon stories, the take-copter is seen attached to the head instead of the waist, similar to a propeller beanie, due to a mishap with Nobita’s shorts. The take-copter has also been attached to objects to enable its flight. One of its disadvantage is its short battery life. Have a build in batteries, speed 80km/hour of 8 hours continous operation possible, if fly slower the battery will last longer. Have some sort of anty-grafity mechanism to blog earth’s gravity. How to use: Just imagine the direction and speed and your thought will transmitted to the mechine. it can move / fly freely. In the first appearence it was called “Dragonfly Helicopter” but after that it was called Take Copter.
Fourth-dimensional pocket / 4D PocketThe inside of this pocket connects to the fourth dimension and acts like a wormhole. It is usually shown attached to Doraemon’s abdomen. Doraemon has a spare pocket which connects to the same location. Nobita has used the spare pocket on ocasion, often for mischievous purposes but sometimes for helpful purposes (for example, he used it to save Doraemon on the movie Nobita and Tin-Plate Labyrinth).
