A fishing reel equipped with a motor case in which a motor for driving a spool and a level winder driving mechanism are accommodated. The motor case is provided with a driving shaft cylinder in which is accommodated a driving shaft and on which is mounted a bearing supporting a spool wall, the driving shaft and a driving shaft cylinder being shiftable into the spool cylinder arranged in a hole defined in the side plate, with an annular cylinder having projection on the circumferential surface thereof, the projections being slidably engageable with slits defined in the inner wall of the side plate when the annular cylinder is fitted to a hole defined in the side plate, with a cylindrical projection supporting a level winder driving gear therein, which is shiftably engaged with a groove defined in the side plate, with a slit defined therein along which is slidable a projection button shiftably arranged in a hole defined in the side plate and protruding from the surface of the side plate by means of biasing force of a coil spring arranged in the hole and with a button slidably positioned through a hole defined in the motor case. The motor case is attached to or detached from the fishing reel housing by means of the slidable movement of projection button through the hole defined in the inner plate of the housing and the slidable movement of the sliding button through the hole defined in the motor case.

摘要:
An image forming apparatus including an image carrying member, a detecting section, and a linear-speed deriving section. The image carrying member carries a toner image. The detecting section detects passages of a mark, provided on the image carrying member, at a plurality of predetermined detection positions. The linear-speed deriving section determines a linear speed of the image carrying member from times at which the detecting section detects the passage of the mark.

An image forming apparatus using an electrophotographic process includes an image forming unit, a storage unit, and a control unit. The image forming unit performs monochrome printing and color printing. The storage unit stores print ratio data that relates to printing in the image forming unit is measured over time. The control unit separately performs correction of monochrome toner density and color toner density based on a predetermined first condition. If the first condition in the monochrome printing is met, the control unit performs correction of the monochrome toner density if a predetermined second condition concerning an amount of variation in the print ratio identified from the print ratio data is also met.

In an image density correction method in accordance with an embodiment of the present invention, an image density correction is carried out by obtaining an actual toner amount through obtaining a density of a between-sheet patch image having been formed during continuous printing, reconstructing relational characteristics in which the actual toner amount is associated with each variation in developing biases, by considering that the actual toner amount and a reference toner amount are to be made in agreement, when a determination that the actual toner amount disagrees with the reference toner amount is made, and resetting a developing bias for realizing the reference toner amount based on the reconstructed relational characteristics and the reference toner amount. By this means, a high quality image can be obtained by suppressing color fluctuations with printing efficiency maintained at a high level even if large color fluctuations occur during continuous printing.

In conventional optical isolators, an optical signal is dispersed by polarization or the characteristics are varied by heat generation in a garnet crystal. According to the invention, the crystal optical axis (3c) of rutile crystal (3) is oriented so that the separation directions of the ordinary ray (O) and the extraordinary ray (E) are perpendicular to the plane including the optical axes of optical fibers (10, 11). Furthermore, the focusing central optical axis (6c) of a focusing rod lens (6) is arranged parallel with optical axes of the optical fibers (10, 11) and at a substantially equal distance from the four rays, i.e. the ordinary ray (O) and the extraordinary ray (E) propagating along the optical axis of the optical fiber (10) and the ordinary ray (O) and the extraordinary ray (E) propagating along the optical axis of the optical fiber (11). An air gap (7) of about 200 [μm] is provided, as a heat insulating means, between the focusing rod lens (6) and a magnetized garnet crystal (8).
