Title: Furniture capable of preventing popping out with earthquake sensing capability
Inventor: NISHIMURO KYUICHI
IPC: A47B96/00
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To prevent falling down of furniture and popping out of drawers and doors in an earthquake to avoid secondary disaster by transferring a weight to a receive part in accordance with the oscillation and inclination of a furniture main body to turn a seesaw member and locking pin to a stopper to prevent motion of the drawers and doors. SOLUTION: When large oscillation and inclination occur at the time of earthquake, a weight 10 moves to a door 3 side on a guide 9 and is transferred onto a receive part 6, which moves downward. Then, a bending part 8c of a seesaw 8 slides in the direction in which it leaves the receive part 6 and is tilted so as to lift a thick wall part 8b of an end part. As result, a locking pin 7 provided on a lower face of the receive part 6 protrudes from a hole on a lower face of a case and passes through a U-shaped space of a U-shaped fitting 11 provided on an inner side of the door 3. The door 3 and the fitting 11 also move to an open side in this condition, but the fitting 11 hits the locking pin 7 so that the door 3 is not opened any more. Consequently, it is possible to prevent objects stored in a cupboard 1 from popping out securely due to the oscillation and inclination.

Title: Circulating type automatic original feeding device
Inventor: SAKAI TOSHIYUKI
IPC: G03B27/62
Filed: 1988-11-09
Abstract: PURPOSE:To simplify a carrying path by making the original reciprocate at an exposing part in a grouping copying mode and exposing it the necessary number of times successively. CONSTITUTION:The original document OD is made to reciprocate at the expos ing part 12 in the grouping copying mode. And exposing is carried out the necessary number of times. For this reason, the original document OD is passed in close contact to an exposing position on an upper surface of a platen glass 12, throughout the whole range, from its leading tip to the end tip, guided by an exposure guiding path 171. Therefore, diversion of focus at the time of exposure with even a part of the surface of the original OD rising from the exposing position on the upper surface of the platen glass 12, does not generate. Further, rising of temperature at an illuminating lamp 13 is prevented by provid ing a fanning path 172 for cooling, in the lower part of the platen glass 12, and fanning by a fan 173. Thus the carrying path can be simplified.
