Title: Optical sensor switch
Inventor: OSHIMA TAKESHI
IPC: H01H35/00
Filed: 1995-02-16
Abstract: PURPOSE: To provide a small-sized multiple circuit optical sensor switch with high reliability by providing one or more light emitting diodes, a plurality of optical sensors, a key top capable of oscillating, and a reflector shifted according to the oscillation. CONSTITUTION: An optical sensor switch 1 for performing four kinds of circuit switch operations, for example, is formed of a key top 5 capable of oscillating, an oscillating body 3, a housing 7, a light emitting diode 9, four optical sensors 4A-4D, and a lower cover 10. The four surfaces of' a quadrangular pyramid 30 mounted on the lower end of the support shaft 3A of the oscillating body 3 are formed of four mirrored reflectors 31A-31D. When the key top 5 is oscillated, the support shaft 3A is inclined, the light beam from the light emitting diode 9 is reflected by, for example, the reflector 31C, and incident to the optical sensor 4C, from which a detection current is then outputted to perform a switch operation. On the other hand, when the key top 5 is not operated, the support shaft 3A remains vertical, and no detection current is outputted from the optical sensors 4A-4D.

IPC: G03G15/08
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a nonmagnetic one-component developing device capable of obtaining a uniform image without the density unevenness of an image by making the diameter of the core metal of a developer supplying roller large in its longitudinal central part, to prevent the oversupplying of a developer to the longitudinal central part of a developer carrier caused by pressing run-off. SOLUTION: The diameter of the core metal 55a of a toner supplying roller 55 is made larger than those of both longitudinal end parts of the toner supplying roller, in its central part. Thus, the strength of the core metal of the longitudinal central part of the toner supplying roller is higher to prevent the core metal of the toner supplying roller from being deflected with pressure by pressing against a developing roller 51, so that a stuck toner quantity in the longitudinal central part of the developing roller is prevented from increasing because of the pressing run-off between the toner supplying roller and the developing roller.

Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To make a cursor unhindering at keyboard operation time, and improve visibility of the cursor when a coordinate input device is operated without impairing operability by changing the cursor to an unhindering position when the fact that an operator releases the coordinate input device is detected. SOLUTION: A proximity sensor 23 is a sensor to detect that a hand of an operator holds a mouse 7, and a proximity sensor control part 21 detects that the mouse 7 is held from output of the proximity sensor 23, and outputs a hold detecting signal MS-HOLD to a host I/F control part 22. Retreat processing of a cursor position is performed by a change in this MS-HOLD, and the cursor position is retreated. The retreated cursor position is returned by return processing of the cursor position. Since these operations are automatically performed when an operator holds or releases the mouses 7, special input is not necessary, and operability is improved.
