摘要
The invention relates to an ink-jet marking device adapted to provide a record, on paper, of the position of a mobile object at given time intervals. The jet-ink marking device shoots tiny drops of ink on a piece of paper as the mobile object is moving. The marking frequency is controled by a quartz frequency generator. The device is adapted to be mainly used in mechanical physics experiments such as estimation of gravitational acceleration, whereby an object is allowed to fall freely and the position of the object at given time intervals is recorded. However the device mentioned herein is also designed for experiments involving air tracks and air tables experiments. An infra-red remote control unit is provided.
