Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate making / printing apparatus, and more particularly to a plate making / printing apparatus having a plate making unit and a printing unit for continuously performing plate making and printing.

2. Description of the Related Art A stencil printing device for making a stencil printing stencil sheet and a stencil printing device using the stencil printing stencil sheet supplied with the stencil printing stencil sheet prepared by the stencil printing means are already known. This plate-making / printing apparatus is disclosed, for example, in JP-A-59-96983 and JP-A-59-143679.

Problems to be Solved by the Invention In the plate making printing apparatus as described above, the plate making and the subsequent printing are automatically performed by a series of sequence control, which requires a lot of artificial operation. However, plate making and printing are not performed in parallel, and when making the plate for the original to be printed next, it is necessary to wait until the previous printing work is completed, and therefore many sheets are printed. When printing the originals in sequence, the next original can be made during the printing by the previous original, compared to the case where a plate making device is used as a separate device, which is separate from the printing device. There is a problem that the print processing time becomes long.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved plate making / printing apparatus which solves the above problems.

Means for Solving the Problems According to the present invention, the object as described above includes a stencil printing means including a cylindrical plate cylinder having a clamp means for locking one end of the stencil printing base paper on an outer peripheral surface, and a roll. A stencil sheet storage means for storing a continuous sheet-shaped stencil sheet for forming a stencil sheet, a stencil sheet feeding means for supplying a stencil sheet for a stencil sheet, and a plate making means Plated stencil stock means for storing the plate-made stencil printing base paper, and a stencil stencil feed roller for sending the stencil printing stencil made by the plate-made stencil stock means toward the stencil printing means and the A stencil sheet stencil sheet feeding device including a stencil sheet cutting device provided on the exit side of the stencil sheet stencil sheet feeding roller, and the stencil sheet making means and the stencil sheet stencil sheet feeding means operate independently of each other. It is achieved by a plate-making printing apparatus characterized in that

According to the above-mentioned configuration, the stencil printing base paper made by the plate making means is stocked in the midway of the stencil printing base paper feeding path from the plate making means to the stencil printing means, thereby,
In the case of printing using a large number of originals, for example, during the printing of the first original, it is possible to carry out plate making by the subsequent originals in advance and stock them, and the printing for each original is performed. Each time the process is completed, the stocked stencil sheet can be sequentially supplied to the stencil printing means. This makes it possible to shorten the entire processing time of printing, especially when using a large number of originals, without impairing the continuous automatic operation effect of plate making and printing.

Another feature of the stencil printing apparatus according to the present invention is to use a continuous sheet-shaped stencil printing base paper as the stencil printing base paper instead of a single-cut sheet, and leave the continuous paper form in the base paper stock section. This means that each time the stencil printing means is sent to the stencil printing means, the stencil printing stencil cutting means cuts the stencil printing paper from the stencil stock part to the stencil printing means. The base paper feeding means for feeding by means of may be a roller type simple one which does not need a sheet separating means for separating and feeding the sheets one by one, and the printing order does not get out of order with respect to the plate making order, Further, there is no problem such that two stencil printing base papers that have been plate-made overlap and are sent to the printing means.

When the plate making means has an electrically controlled plate making means such as a thermal head and plate making is carried out by image information of a time series from a communication line or the like, in the plate making printing apparatus of the present invention, the plate making means is Plate making with given image information can be performed continuously regardless of the printing process, and by completing the plate making based on the image information, a large number of sheets can be continuously printed without requiring a special storage device such as a buffer memory. Image information can be obtained.
