Title: Image forming device
Inventor: SHIRATORI TATSUYA
IPC: G03G15/00
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To inhibits the copying operation of a copying machine if there is not a document on the document table glass of the copying machine having an automatic document feeder. SOLUTION: Control is exerted such that when the absence of a document from the surface of a document tray is detected by a document presence/absence detection sensor and after a lapse of time from the close of a document carrier by a document placing table is stored by a storage device 43a and the lapse of time is over a specific time, the operation of the copying machine is inhibited even if a user operates a copy button. This avoids copying carried out with a document absent from the surface of the document placing table, and prevents a copy in blank paper.

Title: Rotation detecting apparatus
Inventor: SEKI HIDEO
IPC: G01P3/488
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent a rotation signal error from being output being caused by a rattling object to be detected in a rotational direction. SOLUTION: When a code of a differential output s4 between outputs A and B of Hall elements 2a and 2b reverses, a holding circuit 6 takes an output C of a middle Hall element 2c. A level of the output C is different depending on a rotational direction of a gear (object to be detected) 1, and therefore an output prohibiting circuit 8 detects a change in rotational direction on the basis of the level of the output C held by the holding circuit 6. The output prohibiting circuit 8 shuts a power source of an output transistor 7 for an estimated time when detecting the change in rotational direction, thus prohibiting a rotational signal from being output. Only a normal rotation is output as a detect signal and a rotation resulting from rattling is prevented from being detected and output.

Title: Protector
Inventor: MORI HARUO
IPC: E21D19/00
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a protector which secures the safety of operation space with reliability similar or superior to that provided by structures of the prior art although the protector does not have a horizontal brace piece nor a column near its center. SOLUTION: A cushioning material layer 13 is provided on the roof 12 of a protector 1 in such a way as to have a certain thickness. The kinetic energy of an object falling from the top of a tunnel is absorbed by the cushioning material layer 13 and the distance over which the object falls before colliding against the protector 1, i.e., the kinetic energy of the falling object, is smaller than before. Therefore, although the protector does not have a column 11 near its center and no horizontal brace piece is used at the connection between the column 11 and the roof 20, the protector can secure the safety of operation space with reliability similar or superior to that provided by structures of the prior art.
