each cell of the sticker matrix and then stick each cell printed with the
identification onto the surface of the corresponding key top. A key cap from
the accessory bag can be snapped on the key top to protect the sticker (ref. Fig.
3-2). In this way the user may feel a lot easier in using the programmable
keyboard.
At the bottom of the programmable keyboard, the user may find an adjustable
key clip which can be used to pick up the key cap whenever required (ref. Fig.
3-2). The two “feet” of the key clip should be pulled wide for use with double
key and quad key (ref. Fig. 3-5). It is advisable to use a flattop (minus sign)
screw driver to help getting the key top off when necessary (ref. Fig. 3-2, 3-3
and 3-4).
If there is a need to install a key top onto the programmable keyboard, the user
should notice that at the bottom of each key top, one of the four walls is
springy and in the hole on the keyboard to accept the bottom of the key top
there is a protuberance at the lower side. The user should match the springy
wall of key top against the protuberance in the hole (ref. Fig. 3-6) and press the
key top down till a click sound is heard. The key cap (except the blank key)
should be placed after the printed label is stuck onto the key top.
Among the options available for this programmable keyboard is a set of
“numerical keys” which is composed of 12 individual keys each is pre-printed
with one from the set of “0”, “00”, “.”, “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”
and “9”. These numerical keys are moulded in a little different shape from the
normal individual keys and are suitable for the user to create a particular
“numerical keypad” at any zone on the programmable keyboard which is
convenient to the user (ref. Fig. 3-7).
Furthermore, there are blank keys available which the user can use to form
visible partitions or clusters of key tops on the programmable keyboard. When
the user wants to make a group of keys on the programmable keyboard clearly
separated from the rest part of the keyboard for certain specific application,
he/she can use the blank keys to replace the normal individual keys around the
area. The top surface of a blank key is at the ground level of the key stroke for
other keys (ref. Fig. 3-7). The blank key will not be pressed down when
pressed. The user may order for accessional quantity of the blank keys as
option for his/her application.
There are also double key and quad key available for the user to configure the
programmable keyboard such that the most frequently used keys may occupy
larger areas. The double key occupies two “vertically” adjacent positions and
