      In addition, the infrared communication port 52 may be configured by replacing the Bluetooth method or other various communication methods.

Next, the operation of the present invention made as described above with reference to the drawings in detail as follows.

First, in order to print a predetermined data on a sheet-like paper 70 such as a courier waybill or the like via a sheet-fed portable printer according to the present invention, the battery 44 having been fully charged in the lower body 40 is completed. ) Or by connecting an adapter to the power input unit 49 so that a predetermined power from the outside is supplied to the portable printer, and a data cable is plugged into the communication port 50 so as to be portable with an external device such as a notebook computer or a PDA. Interconnect the printers.

As described above, when the preparation for printing via the portable printer is completed, the predetermined power is applied to the portable printer by operating the power switch 48, and the sheet-like form such as a parcel delivery note or the like is delivered through the paper inlet 12. The paper 70 is pushed and supplied.

At this time, the pair of sensing sensors 66 configured to be arranged in a row on the upper surface of the lower body 40 detects the position of the paper 70 to be input, respectively, and transmits the signal to the main control board 54. Accordingly, the main control board 54 controls the printing to be performed only when all signals sensing the position of the paper 70 are input from the pair of sensing sensors 66, while the paper 70 is controlled. If the signal is input only from one sensor 66 because it is not properly input, control is performed so that printing does not proceed abnormally.

On the other hand, a sheet-like paper 70, such as a waybill for printing, is pushed through the paper inlet 12 of the portable printer, and a predetermined key for printing through a notebook computer or a PDA connected to the portable printer is provided. When the operation is performed, the sensor 72 located in front of the pair of detection sensors 66 formed on the lower body 40 has a marking portion 72 formed on the back surface of the paper 70 fed through the paper input hole 12. At the same time as detected by the 66, the main control board 54 drives the drive motor 58 to rotate the feed roller 56.

Accordingly, the paper 70 inserted into the portable printer is automatically moved forward by the rotation of the transfer roller 56 and at the same time the notebook computer or the like through the head 32 located above the transfer roller 56. After the predetermined data transmitted from the PDA is printed, it is discharged through the paper outlet 14.

That is, according to the present invention configured as described above, when performing a print job on a sheet 70 of a sheet form such as a courier waybill through a portable printer, a pair of sensing sensors 66 formed on the portable printer are mediated. By accurately detecting the alignment and the printing position of the paper 70 is fed into the portable printer it is possible to perform a higher quality print job.

Even if the modified embodiments different from the contents described in the present invention are not to be understood individually from the technical idea or the prospect of the present invention.
