ABSTRACT OF THE DISCLOSURE A recorder pen device having a closed cartridge or housing in which is enclosed an ink saturated fibrous material. A writing nib is secured to the cartridge with the opening of the nib communicating with the ink saturated material inside the housing. The nib feeds a smoothly flowing trace of ink to a recording chart upon which the point of the nib is in contact. By providing various tip lengths and staggering the pens, clearance is provided so that the pens can move past each other without interfering with their respective operation. In one form of the invention a retainer is provided for supporting the nib in position on the cartridge. A modified form of retainer serves as the one end cap for the cartridge and is adapted to support the nib in one of two positions whereby the cartridge may be mounted in either one of two 180° opposite positions. Two such oppositely mounted pens can be supported to move past each other without interference. The cartridge is disposable requiring no service during a long period of operation.
