Title: Labyrinth trap
Inventor: KOIKE TADASHI
IPC: F16T1/34
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To surely discharge only condensate by forming fine clearances by a trap casing and a plate member, making the clearances variable according to the displacement of the plate member, arranging the plate member orthogonal to the flow-down direction of the condensate, and elastically urging the plate member in the flow-down direction of the condensate. SOLUTION: A trap chamber 2 part of a body 4 is formed of an inclined wall 9 which is wider downward, and clearances 10 are provided between a plate member 6 and the inclined wall. A regulation screw 7 can appropriately regulate the distance of the clearances 10 by turning a rotary part 13 of an upper end part to vertically move the regulation screw 7 while it is rotated, and increasing/decreasing the clearance between the plate members 6. When the quantity of the condensate flowing from an inlet 1 is large, the plate member 6 is displaced downward by the flow, the clearance 10 is increased, and more condensate is discharged outside from an outlet 3. When the quantity of the flow-in condensate is small, only the condensate is discharged from the outlet 3 in a condition where the displacement of the plate member 6 is small, and the distance of the clearance 10 is small.

Title: Sheet feeder for printer
Inventor: ENDO KENJI
IPC: B65H1/26
Filed: 1989-12-22
Abstract: PURPOSE:To prevent various kinds of troubles caused by improper setting of a sheet feed cassette by installing a set detecting means which detects whether or not the sheet feed cassette is set on a sheet feed deck properly. CONSTITUTION:In case a stopper cover 2 is closed by mistake, an improper setting prevention rib 2a of the stopper cover 2 comes into contact with a sheet feed fore plate 8. Therefore, a window hole 1a for detecting sheet existence which is formed in a unit body 1 dislocates from a sheet existence detecting sensor 5 by the thickness of the improper setting prevention rib, and an anti-reflection part 1b is positioned at the sheet existence detecting sensor 5. With this constitution, light from the sheet existence detecting sensor 5 is absorbed in the anti-reflection part 1b, so that the sheet existence detecting sensor 5 does not detect printing sheet P. As a result, an operational panel displays no sheet. It is thus possible to detect improper setting of a sheet feed cassette A.

Filed: 1990-11-28
Abstract: PURPOSE:To simplify an inner structure of a ribbon to make a low-cost ribbon available by providing a control means conducting one ribbon take-up action every time when a counter counts correction tape take-up actions to the predetermined number. CONSTITUTION:When correction actions and correction tape take-up actions are continuously performed by an input means 1, the number of the actions is counted by a counter 2. After the third action is completed, one ribbon take-up action is performed before the start of the fourth action. At this time, the forward and reverse rotation of a DC motor 4 is controlled based on a control means 3 controlled by the counter, and a printing hammer 5 is actuated. In this manner, when a frame is vertically moved in conjunction with continuous correction and take-up actions, ribbon take-up actions are performed in a constant ratio to prevent the ribbon from slacking due to vibration. Therefore, since a high-accuracy back tension mechanism is not required, a low-cost ribbon with a simple inner mechanism is made available.
