Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a video printer device that prints a video signal onto print paper.

Conventional technology Conventionally, video printer devices have been used to determine whether or not the print paper is genuine before printing, and if irregular print paper is used, the paper is ejected without performing a printing operation. There is.

Hereinafter, the conventional video printer device as described above will be explained with reference to FIGS. 3 and 4.

Figure 3 is a front view of the main parts of a conventional video printer device;
The figure is a block diagram of the same device. Currently, irregular print paper 2 that is not compatible with the apparatus is loaded in the paper feed case 1 mixed with regular print paper 3 that is compatible with the apparatus. When the print execution key 4 is input, the paper feed control means 6 drives the paper feed drive section 6 to feed the irregular print paper 2 and the paper from the paper supply case 1 to the print section 7 . At this time, the paper feed determination means 8 determines from the output of the paper feed detector 9 that the print paper being fed is irregular. In this case, the print control means 10 does not issue a print command to the print section 7, but instructs the paper discharge control means 11 to discharge the irregular print paper 2 from the print section 7. In response to this, the paper discharge control means 11 drives the paper discharge drive section 12 to discharge the irregular print paper 3 to the paper discharge case 13. A paper discharge determining means 15 determines whether the paper discharge is completed based on the output of the paper discharge detector 14. When paper ejection is completed, the apparatus enters a standby state.

When the print execution key 4 is input again, the paper feed control means 6 drives the paper feed drive unit 6 to feed the regular print paper 3 from the paper supply case 1 to the print unit 7. Paper feed determination means 8
determines from the output of the paper feed detector 9 that the print paper being fed is genuine, and prints the print control unit 1.
o controls the printing section 7 to perform a printing operation. After printing is completed, the paper ejection control means 11 drives the paper ejection drive section 12 to transport the print paper from the printing section A to the paper ejection case 1.

Problems to be Solved by the Invention In such conventional video printer devices, if an attempt is made to print when illegal print paper is loaded in the paper feed case, the print paper is ejected without being printed. After printing, the printer enters a standby state, and in order to continue printing, the user must press the print execution key again, resulting in poor usability.

The present invention solves the above problem, and is a video printer device that feeds the next print paper when an irregular print paper is ejected, and prints if it is a regular print paper. The purpose is to provide

Means for Solving the Problems In order to achieve the above object, the present invention provides a paper detector for detecting the presence or absence of print paper in a paper feed case, a paper feed detector for detecting the print paper being fed, A paper feed determination means for determining whether or not the print paper is genuine based on the output of the paper feed detector; a paper ejection detector for detecting the ejected print paper; The paper discharging determining means determines whether or not the paper has been completed, and the paper refeeding determining means determines whether or not to refeed the paper based on the output of the paper discharging determining means and the paper detector.

According to the above configuration, when the paper feed determination means determines that the fed print paper is irregular based on the output of the paper feed detector, the paper is ejected without printing, and the paper is ejected without printing. When the paper discharge determination means determines from the output of the detector that the irregular print paper has been discharged, the paper refeed determination means checks the output of the paper detector, and if there is print paper in the paper supply case, Feed the paper.

Embodiment Hereinafter, a video printer device according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 is a block diagram of a video printer apparatus according to an embodiment of the present invention, and FIG. 2 is a flowchart showing the operation of the apparatus. In step 42, press the print execution key 21.
When inputted, the paper feed control means 22 drives the paper feed drive unit 23 in step 43 to feed the print paper from the paper feed case to the print unit 24 . In step 44, the paper feed determination means 25 determines from the output of the paper feed detector 26 whether or not the fed print paper is legitimate. If it is determined that the print paper is irregular, the print control means 27 does not print, and in step 46 the paper discharge control means 28 drives the paper discharge drive section 29 to print the irregular print paper. The paper is ejected from the section 24. When the paper discharge determination means 30 determines that paper discharge has been completed based on the output of the paper discharge detector 31 in step 46, the paper refeed determination means 32 checks the output of the paper detector 33, and determines whether the print paper is in the paper supply case. If there are any remaining sheets, the paper is fed again in step 43. If the paper feed determining means 25 determines that the fed print paper is genuine in step 44, step 4
At step 7, the print control means 27 controls the print section 24fc to execute printing. If no print paper remains in the paper feed case in step 46, the apparatus enters a standby state in step 49.

Effects of the Invention As is clear from the above description, according to the present invention, even if irregular print paper is mixed in the paper feed case, the print paper is ejected, the next print paper is fed, and the next print paper is fed. If the paper is a regular print paper, printing will be executed, so printing can be performed reliably with a single print execution key manually, improving the reliability and usability of the device.

It can exhibit excellent effects.
