There are provided: a paper folding unit folding and sending a content sheet to a transfer path; an inserter unit sending an insert sheet to the transfer path; an acquiring unit acquiring information on a top/bottom direction and a surface/obverse direction of the content sheet and insert sheet; a merging unit in which the content sheet folded by the paper folding unit is overlapped with the insert sheet; and an enclosing unit enclosing the merged content sheet and insert sheet into an envelope sheet, in which, when the content sheet and insert sheet merge and are overlapped, the content sheet is folded so that the top/bottom direction and the surface/obverse direction of an image of the content sheet match those of an image of the insert sheet, based on the information acquired by the acquiring unit.

Sealed-letter preparing device

In a method for forming a duplicate image by reading an original image from an original sheet and forming a duplicate image according to the original image, to allow the designation of a number of regions for forming duplicate regional images, from an overall image, with desired color separation or other various attributes to be carried out accurately, promptly and simply by mounting the original sheet only once on a digitizer or the like without regard to the number of processes of forming a duplicate image, a plurality of regions designated on a single original sheet are stored in a storage device such as computer memory, either the designated region stored in the storage device or the region other than the designated region is defined as an effective region, a duplicate image of only the effective region is formed for a first process of forming a duplicate image, only the region other than the effective region for the first process of forming a duplicate image is defined as a new effective region, and a duplicate image only for this new effective region is formed for the second process of forming a duplicate image.

Method and device for forming a duplicate image

A stencil printing machine in which a rolled stencil is cut for obtaining a printing stencil of a printing image, the stencil printing machine includes: printing-stencil making section including a thermal head and a platen roller, for making the printing stencil from the rolled stencil held and conveyed by the thermal head and the platen roller; a cutter for cutting the rolled stencil to obtain the printing stencil; and controller for controlling the platen roller such that the front end portion of the rolled stencil separated from the printing stencil by the cutter is moved a predetermined distance backwardly, towards the printing-stencil making section, and then moved forwardly beyond the cutter to a predetermined position.

Stencil conveying device in a stencil printing machine

A stencil printing machine including a stencil presence/absence detector for determining whether or not a stencil sheet is wound on a rotary cylindrical drum when the rotary cylindrical drum is located at a predetermined position of rotation; a memory for storing latest data on the presence or absence of the stencil sheet which is detected by the stencil presence/absence detector and a controller which, in confirmation of the presence or absence of a stencil sheet for a printing process or a stencil making process, reads the latest data from the memory and performs necessary processes according to the latest data thus read.

Stencil printing machine for reducing the time required for stencil

Provided is a vertical movement control device for a paper feed table device which allows a favorable paper feeding action to be carried out at an appropriate paper feed pressure for all kinds of paper without involving any failure to properly lift the paper feed table or any occurrence of seizure of the electric motor, and eliminates any unduly long waiting period even when the required lift of the paper feed table is relatively great due to addition of new paper or removal of paper jamming. An upper limit sensor 19 detects if the upper surface of the paper stack on the paper feed table 1 has reached a prescribed height by the upward movement of the paper feed table 1. The motor 13 is driven in the upward direction in an intermittent manner until the upper limit sensor 19 has detected that the upper surface of the paper stack on the paper feed table 1 has reached the prescribed height, and the duration of the intermittent drive period of the electric motor 13 is gradually increased with the elapsing of time until the upper limit detecting sensor 19 has detected that the upper surface of the paper stack on the paper feed table 1 has been positioned at the prescribed height.

Vertical movement control device for a paper feed table device

A mimeographic printing machine equipped with a sorter for moving a plurality of bins to sort printed sheets, comprises: speed set-up means for setting up a desired print speed; sorter mode set-up means for setting up the sorter for the sort mode; and control means for changing the print speed, which is set up by the speed set-up means, to a predetermined print speed so as to conform to the sorting of the sorter, when the sort mode is set up in the sorter mode set-up means.

Mimeographic printing machine

A mimeographic printing machine comprising: mimeographic printing means for printing an image of an original document on successive sheets one at a time and for discharging the printed sheets; a sorter having a plurality of bins for receiving the printed sheets discharged from the mimeographic printing means; mode setting means for setting up the sorter for a specified mode such that a number of the printed sheets, which are printed for the same original document and exceed the number of the bins of the sorter, will be received on the bins in a specified order; and control means for detecting that the specified mode is set up by the mode setting means and for controlling the mimeographic printing means and the sorter in such a manner that the printed sheets discharged from the mimeographic printing means will be received orderly one after another in the bins, from the first bin to the last bin, and then the following printed sheets discharged from the mimeographic printing means will be received orderly one after another in the bins from the first bin.
