摘要:
A junction/disjunction unit of a multicolored image forming apparatus joints/disjoints a transfer material holder with/from an image holder, to switch over between a monochromatic image forming mode which uses a specific image forming unit and a multicolored image forming mode which uses a plurality of image forming units. For switching the image forming mode, a driving unit for driving the junction/disjunction unit also drives an auger provided for conveying toner, which has been recovered by a transfer material holder cleaning unit for recovering toner remaining on the transfer material holder, into a recovery container. Accordingly, a driving force outputted from the driving unit can be effectively utilized, and thereby good cost performance can be realized.

An image forming apparatus transfers a toner image formed on a photoconductor drum onto a sheet-like recording member while the sheet-like recording member is transported and attracted to a transfer belt, and comprises a jam handling control unit for detecting a transport fault of the sheet-like recording member, and for stopping the transport operation when the transport fault is detected. When the transport fault is detected in a section other than a fixing section, the jam handling control unit first causes the transport operation of the fixing section, and thereafter causes the transfer belt and the transport operation on the upstream side thereof to stop, and any sheet-like recording member remaining on the transfer belt so that the transport mechanism on the upstream side thereof is transported and stopped at the position spanning between the area of the fixing section and the area of the transfer belt.

In an optical scanning device for forming an electrostatic latent image on an image-bearing body with scanning beam released from a light source, a support body having a plurality of supporting faces and first and second optical means for directing the scanning beam from the light source onto the image-bearing body are installed. Moreover, in the support body, a light transmitting means for transmitting the scanning beam from the first optical means to the second optical means is installed in the vicinity of a ridge portion thereof that is the least susceptible to deformation and distortion and strongest in its strength. Thus, it becomes possible to improve a light image in its precision that is formed by the scanning beam directed onto the image-bearing body.

A magnetic head is disclosed. The magnetic head has a block which is formed of a first magnetic material in which a groove for a winding is formed, a first magnetic film which is deposited on a surface of the block in which the groove is formed and is formed of a second magnetic material having a higher saturation magnetic flux density than that of the first magnetic material, a nonmagnetic film which is formed on the first magnetic film and serves as a magnetic gap, a second magnetic film which is deposited on the nonmagnetic film and is formed of the second magnetic material, and a reinforcing block. A portion of the reinforcing block on the side of a magnetic recording medium slide surface is formed of a nonmagnetic material, and the other portion is formed of a magnetic material. A magnetic material-side boundary portion between the nonmagnetic and magnetic materials is inclined to form an acute angle with the nonmagnetic film.

摘要:
The table on which a workpiece is put can travel on a guide rail mechanism relative to a working head with a cutting tool mounted thereon. The table is connected through a nut to a ball screw part to move in an axial direction thereof as the ball screw part rotates. One end of the ball screw part is supported by a bearing and the other end is connected to a servomotor to be rotationally driven. A hollow part is provided in the table to receive therein a damper mechanism part, which comprises a spring, a damper, and a weight, the table and the weight being arranged to enable traveling separately on guide rails. Thereby, even when the workpiece is heavy, the weight can move relative to the table to effectively damp vibrations of the table in a feed direction.
