Claims
- 1. A recording apparatus in which ink can flow from the end of a recording head to effect recording on a recording medium, comprising an ink supply path leading from an ink container to the recording head, and a filter disposed in said supply path and having a number of minute communication bores extending linearly and substantially parallel to the direction of liquid flow in said supply path, said bores being formed by a number of tubes of a ceramic material having hydrophilic properties bundled and integrally shaped in cross-section into the form of a honeycomb substantially without spaces between said tubes, wherein the diameter d of each of said communication bores of said filter is 10-50 .mu.m, the number of communication bores per 1 mm.sup.2 is 20-800 and the ratio of the length L of each of said communication bores to the diameter d of each of said communication bores is at least 10.
- 2. A recording device comprising a recording head, an ink supply path and a filter, wherein:
- said recording head is adapted to effect recording on a recording medium with ink supplied through said ink supply path from an ink container to said recording head; and
- said filter is disposed in said supply path and has a number of minute communication bores extending linearly and substantially parallel to the direction of liquid flow in said supply path, said bores being formed by a number of tubes of a ceramic material having hydrophilic properties bundled and integrally shaped in cross-section into the form of a honeycomb substantially without spaces between said tubes, the diameter d of each of said communication bores of said filter being 10-50 .mu.m, the number of communication bores per 1 mm.sup.2 being 20-800 and the ratio of the length L of each of said communication bores to the diameter d of each of said communication bores being at least 10.
