<p>PURPOSE:To prevent a key depression error without permitting a cord to be entangled to a hand by providing a means for preventing the hand from being entangled by the cord. CONSTITUTION:A coordinate indication device has a device main body 1. A ball part 4 for deciding the coordinate of a cursor in a display screen by a rotational direction and a rotation amount, for example, is arranged at the upper part of the device main body 1 so that it can be rotated. A first key 5 and a second key 6 are arranged in front of the device main body 1, and the keys are used for executing various operations on the display screen such as to select/terminate an icon designated by the cursor and the shift the cursor on the screen by clicking the keys once or twice, for example. A divider 2 for dividing the keys is integrally formed at the intermediate place of the keys with the device main body 1. The exit of the code 3 is arranged at the top part of the divider 2.</p> |
