Abstract
Abstract A manual position indicating device comprises a body portion (1) that can be moved by hand across a surface; and a support member (4) movably mounted to the body portion. The support member includes a graticule (13) and associated signal generating or detecting circuitry for interaction in use with position determining apparatus, whereby the relative positions of the graticule (13) and the body portion (1) are selected by suitably moving the support member and body portion relatively to one another. A cooperating ball (11) and notch system (10) is provided for locking the support member (4) relative to the body portion (1) in a number of different positions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
103 words
A manual position indicating device comprising a body portion (1) that can be moved by hand across a surface; and a support member (4) movably mounted to the body portion, the support member including a graticule (13) and associated signal generating or detecting means for interaction in use with position determining apparatus, whereby the relative positions of the graticule (13) and the body portion (1) are selected by suitably moving the support member and body portion relatively to one another characterised by locking means (10-12) for locking the support member (4) relative to the body portion (1) in a number of different positions.
Claim 2
Dependent Claim
103 words
A manual position indicating device comprising a body portion (1) that can be moved by hand across a surface; and a support member (4) movably mounted to the body portion, the support member including a graticule (13) and associated signal generating or detecting means for interaction in use with position determining apparatus, whereby the relative positions of the graticule (13) and the body portion (1) are selected by suitably moving the support member and body portion relatively to one another characterised by locking means (10-12) for locking the support member (4) relative to the body portion (1) in a number of different positions.
Claim 3
Dependent Claim
28 words
A device according to claim 1, wherein the support member is pivoted to the body portion so that it can swing to and fro in a lateral plane.
Claim 4
Dependent Claim
43 words
A device according to claim 1 or claim 2, wherein the locking means comprises a co-operating ball (11) and notch system (10), the ball being coupled with the body portion (1) while the notch system (10) is mounted on the support member (4).
Claim 5
Independent Claim
