PURPOSE:To effectively detect the malfunction defect of jamming by monitoring the presence or absence of a sheet by a sensor in conjunction with the operation of sheet feeding. CONSTITUTION:A reflection type sensor 9 for detecting the presence or absence of a sheet is disposed near a cutter 4. The printing operation (d) is executed, the sheet is fed to cutting size necessary to issue a ticket (e), and the presence of the sheet is detected by the sensor 9 in this state. Then, the sheet cutting operation (a) is achieved. If the sensor detects the absence of the sheet before entering the cutting operation while there is a command of sheet feeding operation (a), a defect display of stopping the following operation is executed as the malfunction state of a jam. After the sheet cutting is executed, reverse feeding operation (c) is executed corresponding to the reduction in an issued card, and the printing operation is then executed. At this time, if the presence of the sheet is detected by the sensor 9, the following operation is stopped as the malfunction state of a jamming. |
