Next, the printing paper 70 supplied in a reel form from the front of the printing unit 44 of the calendar conveying unit 30 by the forward and backward operation is pressed onto the printing unit of the calendar while the press block is pushed. The advertising section of the company logo is printed on the printing unit.

At this time, the printing paper 70 is supplied in the form of a reel from the bottom to the top, and once the printing operation is completed, the printing paper 70 is progressed to the top of one space, and a new printing medium for the next printing (for example, a new sheet of uneaten paper) ) Can be provided.

On the other hand, when the printed calendar is pushed to one side by a calendar coming for the next print job, the calendar display sheet of the calendar is placed on the guide rod 51 which is bent while drawing a predetermined trace on the rear side of the holder. It naturally leans forward and merges to the pedestal side.

The reason for the automatic folding of calendar displays is that most of the calendars are printed on both sides of the calendar's pedestal so that the printed products can be fed directly to the calendar supply conveyor.

Here, the method of supplying the printing paper while advancing upward one space in connection with the operation of the printing unit, the method of pressing the printing paper on the calendar printing unit surface, and the like, is not particularly limited as long as it is commonly known in the art. Can be adopted without.

The finally printed calendar is ejected by being pushed to one side by a new calendar located next to the printing area, which completes one cycle of calendar printing, while one cycle of such calendar printing is continuously repeated. As such, calendar printing can be performed in a continuous automated process.
