Instead of using traditional pin for this machine. Figure no. (3) shows the shape and parts of pin.

The seventh claim: According to the fourth element, the third annex and the pin is characterized by:

• The plastic head is electrically insulating.

• The round head of the w3w332proposed pin appropriately where it does not impede the movement of the needle.

• The pin was used with a white head, but it is no problem to use it black as in the old pin, it does not affect anything.

The eighth claim; According to the first claim - the fourth annex:

Adjuster to adjust the stitch's length with contrary and prominence signs and numbers:

• Number (5) in annex (4)-( gure 4) represents an indicator to adjust the length of the stitch. It is in the same place of the traditional indicator, taking into consideration increasing its length and make it prominent and its length shall be 1.5 cm.

This is a device adapted to the nature of Visual impairment in terms of the prominence of some parts, or the use of color variation, or use both together that was done during the practical experience.

The adjuster has been prepared by clarifying the numbers in it, as well as the punctuation marks between the numbers by prominence them as well as coloring them in different and contrasting color with the adjuster's background, as well as using colors to clarify the beginning or end of the punctuation marks and to define the adjuster's outer frame.

The ninth claim: According to eight element, the fourth annex, the adjuster is manufactured in the industry:

• The adjuster's background is white or black because the white or black color achieves good contrast with all colors, especially when close-up vision.

• The prominent parts on the top of the adjuster and they are essential in the adjuster's design (in the adjuster's body) to avoid losing some of them and the presence of these pieces makes it easier to adjuster movement when moving to adjust the length of the stitch.

• The indicator is varied and prominent and its height is so large that it is facilitate the touch the prominent numbers or the corresponding prominence of the numbers in the top of adjuster to enable the correct adjustment of the length of the stitch. • Connect the adjuster and provide it with ligi¾;ing by an electric circuit where each number lights up when the adjuster is moved and the number is facing the indicator (for each number different color from the other indicated on it and differentiated by the user), in addition to the prominence in the top of the adjuster.

The tenth claim: According to the first claim - the fifth annex:

Parts of the device and the mode of operation:

• Number (2) in annex (5)-( gure 5) represents a hollow exible arm made with the idea of spring (Yay),its length ranges from 30-35 cm.
