A printer having a hopper without shaft which performs a print operation on a roll of continuous paper. Detection marks are provided in flanges provided in supported members removably attached to the continuous paper, and the presence / absence of the detection mark in a detection position of an optical sensor is determined. A rear end of the continuous paper in the hopper is determined if the result of determination of the presence / absence of the detection mark during conveyance of the continuous paper is the same. A passage length from the position of the determined rear end of the continuous paper to a print unit is equal to or longer than a predetermined maximum print size. By this arrangement, the rear end of the continuous paper can be detected without upsizing the apparatus and without complicating the structure, and the continuous paper can be effectively utilized without causing shortage of the continuous paper during execution of print operation.

A light unit, a backlight, a front light, and a display device, have a structure such that an uneven luminance generated in display is suppressed by radiating light in a sufficient amount even to an end portion of a display region, thereby uniformly radiating light in a sufficient amount to the entire display region, without a complicated structure. The light unit includes a light guide plate and a plurality of light sources, the plurality of light sources being arranged in a line to oppose at least one side surface of the light guide plate, wherein one or more light sources at at least one terminal among the plurality of light sources are positioned outside a lateral edge of a display region, and such a light unit is preferably used in a side-light type backlight or front light.

An optical module includes a light emitting element, a connector part that supports one end of an optical fiber and optically couples the optical fiber to the light emitting element, and a monitoring light receiving element that has a characteristic to increase photosensitivity with an increase in an ambient temperature, and receives a part of components of light emitted from the light emitting element.

A sealing device with a tone wheel formed to seal between a fixed side member and a rotating side member. A slinger comprises a fitting cylindrical part fitted to the rotating side member and a flanged part radially extendedly formed at one end part of the fitting cylindrical part positioned on the outer side of a sealed portion. The outer surface of the flanged part positioned on the outer side of the sealed portion comprises a tone wheel stuck surface on which the tone wheel formed of a magnetic ring is stuck integrally with each other and an extended surface on which the tone wheel is not stuck and extended to the fixed side member. The sealing device is characterized in that a core comprises at least a fitting cylindrical part fitted to the fixed side member, the one end part of the fitting cylindrical part positioned on the outer side of the sealed portion is projected from the outer surface of the flanged part of the slinger to the outside, a part of the seal lip part is formed to be brought into elastically slidable contact with the extended surface of the slinger from the outside, and the flanged part is held by the seal lip part and the other seal lip part from the inside and the outside.

In a torsion beam wheel suspension system, a stabilizer bush made of resilient material is received in a hollow interior of a torsion beam that connect intermediate points of a pair of trailing arms, and retains an intermediate part of the stabilizer to the torsion beam. A bracket including a pair of vertical walls opposing lateral sides of the stabilizer bush is attached to a part of the torsion beam to prevent the lateral shifting of the stabilizer bush without any part of the bracket or stabilizer bush restraining the torsional deformation of the stabilizer or torsion beam. The vertical walls may be spaced apart from the stabilizer bush. The structure is not costly and does not cause any complication or difficulty in the assembly work of the rear wheel suspension system. The bracket may have dual purposes of retaining the stabilizer bush and supporting a dynamic damper.

A power supply coil is disposed on a rear surface of a display via a shield plate. When a current flows in the power supply coil, a magnetic flux emitted from the power supply coil traverses an opening of the shield plate. As a result, the power supply coil and the shield plate are electromagnetically coupled and the shield plate defines and functions as an antenna. Accordingly, a communication terminal communicates favorably with a smartcard, which is a device positioned on a front surface side of the display.

A shock absorber includes a shock absorber main body composed of a vehicle-body side tube and a wheel side tube and formed with a lubrication clearance, a damper including a cylinder, a piston which partitions the interior of the cylinder into two working chambers, and a rod, a reservoir chamber composed of an air chamber and a working fluid chamber, a partition wall member for partitioning the working fluid chamber into an upper working fluid chamber and a lower working fluid chamber, a flow path having a check valve for permitting only a movement of the working fluid from the upper working fluid chamber to the lower working fluid chamber, and a communication path for allowing communication between the lower working fluid chamber and the lubrication clearance. A cross-sectional area of the lubrication clearance and that of the rod are different.
