Title: Facsimile equipment
Inventor: TANAKA HIDEKI
IPC: H04N1/00
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To print out a seal stamp on an original with a proper density held for a long time by providing a control means that sets a press time of pressing a stamp member onto an original and depresses the stamp member continuously for the press time by means of a print means. SOLUTION: A print unit 17 excites an electromagnetic solenoid 17a for an input period of an excitation signal to extend a drive shaft to allow a stamp member 17b to be protruded toward an upper guide plate 5. As a result, the print unit 17 presses the stamp member 17b onto an original D to print out a seal stamp in ink from the stamp member 17b at a prescribed position of the original D. In this case, a CPU allows a timer to count a time after the exciting signal is outputted to the print unit 17 and interrupts the exciting signal in a timing when the count time reaches a preset press time thereby turning carrier roller pairs 8, 9 and a paper discharge roller pair 18 and restarting carriage of the original D.

Title: Device for detecting thickness of a sort of paper
Inventor: SASAKI MASAMITSU
IPC: G01B5/06
Filed: 1985-06-05
Abstract: PURPOSE:To measure directly thickness while a sort of paper is transported by facing and disposing a drum and a cam in a shape where length from a center to an outer periphery is changed by holding the transportation path of a sort of paper and detecting the rotational angle of the cam. CONSTITUTION:The drum 5 is pivotally supported by aligning it with a transporting roller 4 forming the transportation path 2 of a sort of paper, and the cam 6 is supported so as to rotate in such a way that it faces the drum 5 and the transportation path 2 so as to hold them. The cam 6 is made into such a shape that the length from the supporting center point to the outer peripheral surface changes slowly. When a sort of paper is transported in such a way, the rotational angle of the cam 6 is detected to measure the thickness of a sort of paper, because the cam 6 turns until a clearance between the drum 5 and the cam 6 equals the thickness of a sort of paper. Thus a sort of paper with different thickness can be sorted out while it is transported.
