Publication number: 20010042468Abstract: A printer includes a printing mechanism and an ink container. The ink container includes a cylinder having a side wall and provided with an ink discharge port in its front end face, a piston received in the cylinder to be slidable along the side wall of the cylinder, and ink between the piston and the front end face in the cylinder. An LED projects light onto the side wall of the cylinder in a predetermined position in the longitudinal direction of the cylinder, and a phototransistor is positioned near a rear end face of the cylinder to be adapted to receive the light projected by the LED and passing through the side wall of the cylinder only once, and outputs an electric signal upon receipt of light. The remainder of ink in the ink container is detected on the basis of the output of the phototransistor.Type: ApplicationFiled: May 22, 2001Publication date: November 22, 2001Inventors: Hideaki Inoue, Makoto Miyaki
