摘要:
Strap-like step portions each having a smaller external diameter than the external diameter of an ink supply roller are provided at opposite ends of the ink supply roller provided in a drum. Guide surfaces of ink dams urged by springs are brought into contact with the strap-like step portions respectively. Inclined surfaces of the ink dams are brought into contact with the strap-like step portions and side end surfaces of the strap-like step portions respectively. Ink leaked onto the strap-like step portions is led to the inclined surfaces in conjunction with the rotation of the ink supply roller and returned to the inner side of the ink supply roller. Ink is prevented from being leaked out of the ink supply range of the ink supply roller, so that a printing apparatus and sheets of printing paper are not stained with ink. The state of contact between the ink dams and the ink supply roller is kept stable. If the elastic force of the springs is changed, the state of contact can be changed.

A printing drum of a stencil printing machine is formed of a base member having two annular members spaced apart from each other and a transverse bar connecting the two annular members; a flexible multi-porous sheet having a filled portion at at least a part of a peripheral portion except a central portion thereof and being wrapped into a cylindrical shape around the outer peripheral surface of the base member, and around which a stencil sheet is wrapped; a spring member situated between one end of the flexible sheet and the base member to attach the flexible sheet resiliently on the base member; a stencil clamping device provided on the transverse bar for selectively clamping one end part of the stencil sheet; and an inner pressing device situated inside the flexible sheet for supplying ink outwardly. The inner pressing device pushes the flexible sheet radially outwardly when the base member and flexible sheet assembly rotates. Sliding areas are formed at portions of the annular members contacting the filling portion of the flexible multi-porous sheet. Thus, the flexible sheet can smoothly move on the annular members.

A stencil printing screen body includes an ink-previous printing area, an ink-impervious non-printing area provided around the printing area, and a pressure sensitive adhesive area formed on the surface where the stencil sheet of non-printing area is attached and having adhesion to the stencil sheet. The stencil printing body is wrapped in a cylindrical form on peripheral surfaces of annular members, and a squeeze member is provided in the screen body for supplying ink. The stencil sheet is applied onto the screen body without leaking ink.

A starter driving semiconductor switch apparatus energizes and de-energizes a starter according to a command from an outside. A series circuit to which semiconductor switches are connected in series is provided between a battery serving as a power supply and the starter. The starter is energized by bringing all the semiconductor switches into conduction. A voltage or a current at a predetermined point in the series circuit is monitored to make a self-diagnosis on whether the starter is allowed to start and whether there is a failure in the semiconductor switches according to a monitor output. The starter driving semiconductor switch apparatus is thus expected to have a longer useful life by energizing the starter not by using mechanical contacts but by using semiconductor switches.

There is a disclosure of a system which controls a folding unit performing folding processing to one set of sheets supplied by a print unit. The one set of sheets includes sheets of a first size and/or a second size which is smaller than the first size. The system includes a first controller and second controller. When the one set of sheets includes a sheet of the first size, the first controller inhibits the folding processing to a sheet of the second size. When the one set of sheets does not include a sheet of the first size but includes a sheet of the second size, the second controller permits the folding processing to a sheet of the second size.
