Claims

A printing paper detecting device comprising: a paper detecting sensor for detecting a printing paper amount; and a control unit for estimating a paper amount according to a result detected by the paper detecting sensor.

The printing paper detecting apparatus according to claim 1, wherein the paper detecting sensor detects a pressure of the printing paper and outputs a current value corresponding to the amount of the printing paper.

The image forming apparatus according to claim 2, wherein the control unit includes a memory storing current value data corresponding to a printing paper amount, reads the current value output from the paper detecting sensor from the memory, and estimates a paper amount corresponding thereto And the print medium amount detection device is configured to print the print medium amount detection signal.

The printing paper detecting device according to any one of claims 1 to 3, further comprising a display unit for displaying an estimated printing paper weight.

A printing paper detecting method of a printing apparatus including at least a paper detecting sensor for detecting a printing paper amount and a memory for storing information on a paper amount that can be detected by the paper detecting sensor, And then estimates the amount of paper from the memory with the inputted information after inputting the sensed information.

The printing paper detecting method according to claim 5, wherein the amount of paper detected by the paper detecting sensor is a value of a current corresponding to a pressure of the paper.

The printing paper detecting method according to claim 5 or 6, further comprising the step of displaying an estimated paper amount from the memory.
