Title: Image forming device
Inventor: SAITO TAKESHI
IPC: G03G15/01
Filed: 1986-10-06
Abstract: PURPOSE:To prevent the developers of plural developing units from mixing with each other with a simple constitution by rotating a latent image carrier before a prescribed developer carrying member gets in a development position at the time of rotating a developing unit. CONSTITUTION:With the development roller 10 of a 1st developing unit 3 in the development position, a key 27R or 27B is depressed to rotate the developing unit 1 in the direction of an arrow (a). Before the development roller 10R or 10B in the selected developing unit gets in the development position, a photosensitive body 11 is rotated clockwise by an angle theta. Thus, the developer (toner) T moving to the photosensitive body 11 from the development roller 10 is separated from a development area D by the angle theta. Hence the development roller faces the clean surface of the photosensitive body without the developer when the selected development roller gets in the development position. The developer T attaching to the photosensitive body never mix with the developer on the development roller 10R or 10B getting in the development position. Consequently the color change of a visible image, which is caused by color mixing, never occurs.

Title: Eaves edge structure
Inventor: TSURUNO OMIHISA
IPC: E04D13/076
Filed: 1994-10-03
Abstract: PURPOSE: To surely receive the rain water falling from a roof and prevent an eaves edge from being broken by accumulated snow by fitting a tubular body rotatable centering on the axis between an eaves gutter and a roof tip section. CONSTITUTION: An eaves gutter 3 is fitted to a hanger 5 below the tip section 21 of a roof 2, and a tubular body 4 is fitted to the hanger 5 along the eaves gutter 3 between the eaves gutter 3 and the tip section 21. Many vanes 41 are provided on the outer periphery of the tubular body 4, and the tubular body 4 is rotatably supported by bearings 45, 45 fitted at the upper end sections of arms 42. The rain water falling from the roof 2 collides with the vanes 41 and falls into the eaves gutter 3 as if being twined on the outer periphery of the tubular body 4, and the rain water can be surely received by the eaves gutter 3. When snow falls on the roof 2, the accumulated snow protruded into a block shape at the tip section 21 slidingly falls to the outside of the eaves gutter 3 while rotating the tubular body 4. The collision energy at the time of falling is weakened by the rotation of the tubular body 4, and the breakage of the eaves gutter 3 can be prevented.

Title: Sheet feeder
Inventor: HIRANO HIROFUMI
IPC: B41J13/10
Filed: 1985-10-28
Abstract: PURPOSE:To make pinch rollers in plural rows also releasable easily, by making the opening part of a sheet guide member so as to shift when rotating this sheet guide having a regular interval with a circumferential surface of a sheet feed roller, and to let a pressure-contact member run on the guide member, then to release the pressure contact. CONSTITUTION:When a recording sheet's edge is trued up or it is conveyed with a pin tractor feed system, if a releasing lever is operated and a sheet guide member 5 is rotated in a rotational downstream direction of a feed roller 1, a releasing cylindrical part 8b of a pinch roller 8 runs on a releasing part 7c, therefore a pressure-contact part 8a of the pinch roller 8 comes off an outer circumferential surface of the roller 1, whereby each pressure-contact state of these rollers 1 and 8 is released, and furthermore a sheet keeper 10 also separates from the outer circumferential surface of the roller 1. Accordingly, the recording sheet is feedable along the outer circumferential surface of the roller 1 without any resistance. Thus, since pressure contact between a feed roller and a pressure-contact member is made so as to be released by rotating the sheet guide member, pinch rollers in plural rows also are easily releasable without installing any releasing member.

A single piece of the data 210 to be retrieved is extracted out of a storing area 107 fro data to be retrieved. Then a partial coincidence detecting mechanism 108 checks whether or not the data 210 contains 'AMERICA' or 'AFRICA'. If the partial coincidence is detected, the corresponding data 210 is displayed at a terminal 103 as one of retrieving data.
