Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing device for a binding such as a calendar.

Conventionally, a special printing machine was used to print the orderer's company name or trade name on the bottom of each sheet of a 7-page or 13-page calendar with a cover. In this printing machine, a calendar is set on a table, and the printing mechanism moves back and forth to print on predetermined locations on the paper sheets, but the upper paper sheets are manually printed one by one. The operation of turning pages is not only labor-intensive but also inefficient.
In particular, there was a lack of safety, with fingers sometimes getting caught in the machine and causing injuries.

The present invention has been developed in view of the above circumstances, and allows automatic setting of a garenda (booklet) in a fixed position and setting on a booklet supporting device, and also reduces weight as compared to the prior art. The structure is simplified by reciprocating the calendar without reciprocating the heavy printing mechanism, and the simple structure automatically turns printed sheets, improving safety and printing. The purpose is to provide a highly efficient printing device.
