The prototype "Everest Champion" (1964, Bicycle Culture Center collection) by Tsuchiya Seisakusho for the 1962 Tokyo Olympics is also drawing attention.
A unique special exhibition "Scene with a bicycle" that approaches bicycles from an art perspective will be held from 17th to 9th September. → Continue reading

The word "prototype" (prototype) is different from experimental machines, test machines, prototype machines (cars), etc.Formula(Official) Decide to hirecompetitionSometimes it is lost in mass production after all, and there is no strict distinction.
Created for testing purposes, such as before moving a new product to mass production, to avoid problems due to product design and other issues.MalfunctionCan be found and will be considered for a specific modification. By doing this, mass productionMarketYou can prevent the problem from being discovered after going to.
If it is determined that the production prototype is sophisticated enough to meet its functionality, toughness, productivity and other goals, the product can be put into production. Often, a large number of prototypes for such applicationsIndustrial scienceManufactured using a different technology. The techniques and methods for this arePrototypingCalled.

Adobe_DirectorUsing tools such as, you can create prototypes and demonstrations such as menu screens more quickly than in a normal development environment. In addition, there is an incompatibility with the actual development environment, so there is an advantage that the prototype can be certainly destroyed.

These vehicles形式(EF66 type ← EF90 type) Or different series number (JR East E231 series 900 series ←209 series 950 series), appearance andComposition/organizationEtc. are different from mass-produced vehicles (Series 300 Shinkansen J1 formation,E3 Series Shinkansen R1 formation ← S8 formation,JR West Japan 207 Series F1 formationand so on. Although it is often modified to suit mass-produced vehicles, it is not uncommon to continue to use it as it is.
In addition, if mass production is postponed, it may be a vehicle with only a small number of power or one type 1 car (in the formerJNR 207 series,JNR 713 series, In the latterJR East Kuha 415-1901AndJapan Freight Railway(JR Freight)EF500 typeandED500 typeIs an example). For vehicles that have completed a series of tests and vehicles that have been put off mass production,OperationBefore the vehicle age is less than 10 years due to inconvenienceScrapped carIn some cases (in the latter caseJR East E331 seriesSuch). In addition, some vehicles have been scrapped without conducting a test, let alone commercial operation (JR Hokkaido Kiha 285 series railcarIs an example).JR Tokai OfN700 series,N700S seriesLike the preceding prototype car (9000 series), after the appearance of the mass-produced car, it is not put into commercial operation, but there is an example in which it is used as a test formation as it is.
Technically,CreatureAnything that is not, including structures, equipment and accessories,NATURE OfLandscapeEverything is useful as a prototype. EspeciallyDiorama,Layout, The case where it is used as a reference in order to produce a scenery (modeling of terrain and landscape in a railway model) is applicable.
However, in North America the following are preferred prototypes:
- Automobile(1957 modelChevroletMany models were manufactured)
- weapon(For exampleM4 Sherman tank.. OtherArmored car-Battleship-FighterSuch)
- Rail vehicles and facilities
- オ ー ト バ イ
- Space ship(ア ポ ロ,Saturn v,ISSSuch)
Fiction items (eg,Star Wars,ス タ ー ト レ ッ クIt is open for debate whether the spacecraft ofEur-lex.europa.eu eur-lex.europa.eu,dolls(EspeciallyAction figure) Is never called a "prototype" for the humans and creatures that are the models when it is produced.
In Japanese models, the word prototype is often used for small-scale production/small-distribution prototypes made at the individual level, as well as corporate prototypes/mass production precursors.
"Mobile Suit Gundam]Real robotOf the lineAnimeSo, I wasn't originally a pilot of the prototype aircraftheroOne of the standard story patterns is that the story is unfolded as a result of being boarded and piloted by accident. In such works, the story is developed with the prototype machine that the hero boarded as the protagonist. In addition, even in the case of a controlled machine, it can be seen that a small-volume machine that is virtually the same as a prototype machine is the leading mechanism.
When the prototype machine is the main character's boarding machine, the story development may be made in which "mass production machine" and "successor machine" appearing in the play are modeled from this. In this pattern, the aircraft that is positioned as a mass production machine / successor aircraft is detuned compared to the prototype aircraft in terms of maneuverability and combat ability in order to give priority to productivity improvement, cost reduction, stable operation of the aircraft, etc. There are many.
However, in actual weapons, most mass-produced machines have improved problems found in prototypes, so mass-produced machines have higher performance.It is extremely rare for the prototype to be superior. In the case of the succeeding machine, it is basically that the performance is improved by the improvement. In the case of anime on the real robot route,"One-of-a-kind special that ignores profitability and stability (One off) Machine"Or"Experimental machine with the latest technology" "Only a person with special abilities and elements can exhibit the prescribed performance(Many people with maneuvering ability cannot be secured even if they are mass-produced as it is)” is often set.
In addition to this, there are small variations for each work, but in many works, the prototype machine is set to be higher performance than the mass production machine for some reason, and the mass production machine is destroyed in large quantity or thoroughly. RuHurtIs carried out, which makes the prominence of the protagonist's strength and the protagonist's machine outstanding.
