Title:
【発明の名称】インクジェット装置のための液滴検出器
Document Type and Number:
Japanese Patent JP2001505498
Kind Code:
A
Abstract:
A drop detection apparatus has a thermosensitive substrate for receiving drops of ink and providing a signal representative of a change in the temperature in the thermosensitive substrate which is caused by the ink drops deposited on the thermosensitive substrate. The thermosensitive substrate is made from a pyroelectric material, such as, for example, polyvinylidene fluoride (PVDF) and lead zirconium titanate (PLZT). As a result, a drop detection apparatus has a substantially simplified structure for detecting drops of ink ejected from large numbers of jets. Furthermore, since a drop detection apparatus relies on the temperature difference between the thermosensitive substrate and the drop of ink which is substantially small in size, the drop detection apparatus can be made substantially small in size, therefore suitable for a small sized ink jet apparatus.
