Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stencil printing machine for performing a stencil printing on a stencil sheet by thermally stenciling a desired image on a stencil sheet and transferring ink from the perforated portion of the stencil sheet to the printing paper. More particularly, the present invention relates to a stencil printing apparatus capable of writing a plurality of original images in an image writing area in a well-balanced manner.

[0002]

2. Description of the Related Art Conventionally, a stencil printing apparatus using a stencil sheet has been known as an image forming apparatus for writing a document image signal read by a CCD or the like in a document reading section.

A stencil printing apparatus of this type performs stencil making on a stencil sheet in a stencil writing section comprising a thermal head and a platen roller based on an image signal of a document, winds the stencil sheet on the printing drum, and thereafter prints the stencil sheet. Printing is performed by transferring the ink that has been extruded from the stencil sheet and that has passed through the perforated portion of the original image formed on the stencil sheet to printing paper.

Many stencil printing apparatuses of this type perform writing by arranging two B5 size document images side by side on printing paper having a B4 size document writing area, for example.
It has a so-called continuous printing function of making a plurality of original images on a stencil sheet for one plate.

In a conventional stencil printing apparatus, when stencil making is started using the continuous shooting function, an image of a first original to be continuously shot is read by an original reading unit. Simultaneously with this operation, the original image is thermally stencil-made on a stencil sheet by a stencil making section having a thermal head and a platen roller. Then, after the end of plate making for one original with the first original, the apparatus is temporarily stopped to wait for setting of the next original. When a predetermined time (e.g., 15 seconds) fixed in advance for waiting for setting of a document elapses, or the user presses a restart key within the predetermined time,
Start platemaking for the next manuscript. By this repetitive operation,
A plurality of original images are made on a stencil sheet of one plate length.

[0006]

However, when the continuous printing function is used in a conventional stencil printing apparatus, a waiting time for setting the next original (hereinafter referred to as a continuous shooting waiting time) is fixedly set in the apparatus in advance. Therefore, the user cannot arbitrarily change the continuous shooting waiting time.

In the conventional stencil printing apparatus, if the continuous photographing waiting time is exceeded, the next stencil making operation is restarted even if the original is not set on the image reading section, so that a desired stencil cannot be produced. There was a case.

For example, when a book is used as a document and plate making is performed using images with different pages, it is necessary to turn the pages of the book after the completion of plate making using the first document, and it takes time to prepare the next document. . If the continuous shooting waiting time is exceeded while the next document is being prepared, the prepress operation is performed without setting the next document. For this reason, the plate creation at that time becomes useless, and a situation arises in which the plate must be created again.

In view of the above, the present invention is capable of arbitrarily setting the continuous photographing waiting time in the continuous photographing plate making operation processing, extending the continuous photographing waiting time arbitrarily, and reliably producing a desired plate without failure.

By pressing e and operating the numeric keypad 102a, the continuous shooting waiting time can be set to an arbitrary time.

If it is determined that the original cannot be prepared during the continuous shooting waiting time set during the continuous shooting operation standby, the stop key 102f of the operation panel 101 must be pressed until the continuous shooting waiting time elapses. , The continuous shooting waiting time can be extended.

Since the extended continuous photographing waiting time is not canceled unless the plate making start key on the operation panel 101 is pressed, a sufficient time necessary for preparing the original for setting the second original on the image reading section 2 is required. The plate making operation can be resumed. As a result, it is possible to reliably create a desired plate, without the plate making operation being automatically restarted due to the time lapse and the plate creation being failed as in the related art.

In the above-described embodiment, the configuration has been described in which the continuous shooting waiting time can be arbitrarily set using the waiting time setting key 102e, but the present invention is not limited to this configuration.

Is to be resumed. Specifically, when the stop key 102f is pressed during the continuous shooting operation, the continuous shooting waiting time is extended, and when the plate making start key 102b is pressed, the continuous shooting operation is restarted. It is not limited to this configuration.

More specifically, as shown in FIG. 8, when the stop key 102f is pressed during standby for the continuous shooting operation, the timer 105a of the control means 105 resets the time counted up to that point, and restarts the timer again. It may be configured to measure the time of 105a. For example, the setting time of the continuous shooting waiting time is 1
In the case of 5 seconds, if the stop key 102f is pressed when the timer 105a of the control means 105 measures 5 seconds, the timer 105a is reset, and the timer 105a is restarted from 0 second. And timer 1
When the time of 05a exceeds 15 seconds of the continuous shooting waiting time, the plate making process is executed under the control of the control unit 105.
This can prevent the stencil printing apparatus 1 from continuing to stop in a halfway state (continuous shooting standby state).

In the above embodiment, the configuration using the stop key 102f as a key for extending the continuous shooting waiting time has been described, but the present invention is not limited to this stop key 102f. For example, the operation panel 101 shown in FIG.
, A reset key (not shown), a combination of a plurality of keys, a soft key such as a touch panel, and a command input. The operation keys 102 on the operation panel 101 are
