Keyboard Stamps
Keyboard sized stamps that type entire words, and potentially entire sentences. | |
These stamps are the size of keyboards, and have large handles for ease of use. Each letter is sequentially arranged by reduced depth, each offset just enough to allow for one depression to type an entire word maximizing efficiency.

By the time the last letter (or key) goes down, the first one has been pressed down for a while. Is there a risk of the held-down key repeating or jamming the input, or do you need a hammer mechanism like on a piano, to retract the key after it's been pressed? |

Take the pegged cylinder from a music box, flatten
it out, and set up so each peg strikes a metal
finger, pushing straight down on the plunger
which presses the key. Then, the finger passes
the peg (ping!) and another one can play its key. |

You'd need several plates, and the handle would
have a long distance of travel (number of
keypresses * keystroke length) but you'd gain the
ability to use a single key multiple times, for which
your vowels will thank you. |
