key or typehead of typebar or arm, in Parkinson

Parkinsonの用語選択というか 誤用?が 結構あとあとに影響? keys..

Background on keyboard design

  • photo of early typewriter
    • この挿入写真というかイラスト? 右サイドにあるのはスペースキーか? カリグラフ?にしては段数が少ないし 奥行きも乏しい、、

It turns out that this keyboard was designed experimentally by Christopher Sholes, the inventor of the typewriter, to slow the typist down. The keys on the early machines hung down in sort of a basket arrangement, and pivoted up to strike the platen (roller) from underneath. To see what you had typed, you had to lift up the roller so you could look at the paper. Since the keys had no springs on them, they fell back into place by gravity. This meant their action was very sluggish and if two keys that were close together in one quadrant of this ``basket'' were struck rapidly, one after another, they would jam.

The Dvorak Simplified Keyboard: Forty Years of Frustration

誤用ではなく 意図された用語法であったか? それはないかな。

あるいは Parkinsonは key と typebarの両方の一挙動作性を keyを用いてあらわしていたのか?

いや それでは

  • The keys ……, pivoted up to to strike the platen(roller) from underneath.
  • The keys ……, they fell back into place by gravity.

の説明がつかない というか、 プラテン下面を叩くのは typebar だし、gravityで落ち戻るのもtypebar、、

key leverは spring back してたようなきがするし。

誤用であった場合

Parkinsonのマシン記述において、少なくともこの部分の"key"は タイプバーのことあるいはそのタイプヘッドのことのような。そう読み替えると、

On the early machines

  • The keys typebars hung down in sort of a basket arrangement, and pivoted up to strike the platen(roller) from underneath.
  • The keys typebars had no springs on them, they fell back into place by gravity.
  • This meant their action was very sluggish and if two keys typebars that were close together in one quadrant of this "basket" were struck rapidly, one after another, they would jam.

Parkinsonのこの部分の記述においては タイプバスケット上の配列のことしか語っていない。keyboard上のキー配置への波及についての言及はあるのか?ないのか?

あるいは タイプバーのことを keyと呼ぶ慣用表現も あったか。
