摘要:
The rotation of the inner press roller 16 is synchronized with the rotation of the printing drum 10 by the gear train including a gear wheel 22 coaxial with the printing drum, a gear wheel 24 meshing with the gear wheel 22 and rotatably supported by an arm 26 swingable about the central axis of the printing drum, and a gear wheel 28 meshing with the gear wheel 24 and coaxially connected with the inner press roller 16 to rotate therewith and rotatably supported by an arm 18 swingable about a pivot axis Ob parallel with and distant from the central axis Oa of the printing drum. A clutch 86 is provided to apply a torque from the printing drum when driven to the arm 26 to control the biasing out operation of the inner press roller 12 against the circumferential wall 12 of the printing drum. The clutch may be replaced by the linear actuator 96. The clutch or linear actuator may be temporarily actuated stronger during a starting up of the printing operation. The distance between the axes of the gear wheels 24 and 28 may desirably be restricted not to increase beyond a predetermined distance.

In the gear train, a brake 86 or 90 is provided for braking the gear wheel 28 or 24 to control the biasing out operation of the inner press roller 12 against the circumferential wall 12 of the printing drum. The braking action may be temporarily increased during a starting up of the printing operation. The distance between the axes of the gear wheels 24 and 28 may desirably be restricted not to increase beyond a predetermined distance.

A sticky sheet which is to be disposed of is fed in a first direction parallel to its surface so that its leading edge abuts against a stopper construction. The sticky sheet is then further fed in the first direction and is folded up in a second direction substantially perpendicular to the first direction into several layers against the stopper construction, these layers resting upon a plane support construction which extends from the lower part of the stopper construction in the direction opposite to the first direction. Then the superposed layers of the folded sticky sheet are moved in a third direction substantially perpendicular to the first and second directions while being compressed together so as to stick them together so as to be disposed of in the form of a relatively thick and narrow strip including several superposed layers which are adhering together due to their stickiness. A machine is also disclosed for disposing of a sticky sheet in the above described way.

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.
