摘要： A roll-paper printing system comprises carry-amount detecting means, recording means, and updating means. The carry-amount detecting means detects a carried amount of the roll paper; the recording means records amount information regarding an amount of the roll paper; and the updating means makes the amount information be recorded on the recording means based on the carried amount detected by the carry-amount detecting means. The updating means makes the amount information be recorded on the recording means when a physical process for indicating a break in roll-paper usage is conducted to the roll paper.

摘要： A space for housing an optical sensor is formed between a detection gear of a drive transfer gear and a frame for supporting the detection gear. A detected part shaped like comb teeth is formed integrally on inner walls of the detection gear. The optical sensor is placed so that the detected part passes through a space between a photo emitter and a photo receptor of the optical sensor. Since the detection gear and the frame protect the optical sensor from stray light and interfering substances such as paper powder, or the like, a high-reliability, small-sized detection mechanism can be provided.

摘要： A method of detecting the amount of remaining sheets of paper in a paper feeding cassette of a printing apparatus, wherein the printing apparatus receives a paper feeding cassette having a knock-up plate on which paper is placed, and which pivots as paper is removed therefrom, a pickup roller installed in the printing apparatus which elastically moves up and down within a predetermined range to contact the paper, the pickup roller being made to rotate in close contact with the paper to sequentially feed the paper into the printing apparatus, a lifting mechanism which lifts the knock-up plate step by step according to the consumption of paper, thereby placing the loaded paper against the pickup-roller, calculating a difference in the number of operations of the lifting mechanism for lifting the knock-up plate toward the pickup roller when a maximum number of sheets of paper is loaded into the paper feeding cassette and when only a single sheet of paper is placed in the paper feeding cassette, calculating an amount of consumed paper per one operation of the lifting mechanism as a set value from the calculated difference, lifting the knock-up plate when the paper feeding cassette enters into the printing apparatus until the loaded paper closely contacts the pickup roller, and counting the number of operations of the lifting mechanism, and calculating the amount of paper remaining in the paper feeding cassette based on the number of operations counted and the set value calculated. As a result, a user is always able to roughly determine how many sheets of paper are left in the cassette, thereby avoiding situations where the printing job is stopped due to a lack of paper.
