Changing the lead in certain Pica pencils, like the Pica Fine Dry model shown in the reference, is a straightforward process facilitated by the pencil's mechanical design.
Understanding the Pica Lead Changing Mechanism
The reference provides insight into how the lead is advanced or "changed" in a Pica Fine Dry pencil once the current lead runs out.
- Automatic Feeding: According to the video snippet, "So when you run out you can just keep on pressing. And it will feed you another one out..."
- Simple Action: This indicates that to get a new piece of lead ready for writing when the current one is fully used, you simply continue pressing the pencil's advancing button.
- Internal Supply: This process implies that the pencil holds multiple leads inside an internal reservoir or magazine and automatically pushes a new lead into position when the button is pressed after the previous lead is exhausted.
Step-by-Step Lead Changing (Pica Fine Dry Model based on reference)
For the specific model referenced:
- Use the pencil until the lead is too short to write with effectively or runs out completely.
- Press the advancing button on the pencil.
- If there are leads stored inside, the pencil will automatically feed the next lead forward.
- Repeat pressing until the new lead extends to your desired writing length.
This method, described in the reference, shows how the pencil automatically manages the transition to a new lead from its internal storage simply by pressing the actuator. While the reference doesn't detail how to initially load leads into the internal reservoir, it clearly illustrates the 'changing' process of getting a new lead ready once the previous one is finished, making it a simple, press-to-feed action.
