Provided is a press molding method in which a plate material is molded into a target molded body including a ridge section, said method including: a first step for molding an intermediate molded body; and a second step for forming the target molded body from the intermediate molded body. The target molded body and the intermediate molded body have coincident regions where the cross-sectional shapes coincide on both sides of an intermediate ridge section, and an intermediate region where the cross-sectional shapes do not coincide. The intermediate region includes: an outer region in which the intermediate molded body protrudes outward of an edge radius with respect to the target molded body; and an inner region in which the intermediate molded body is curved inward of the edge radius with respect to the target molded body.

This press forming method includes a first drawing step for forming a first drawn step portion, a second drawing step for forming a second drawn step portion, and a finishing step for completing a stepped portion. In the first drawing step, a first outside curved portion is formed to the outside of a second outside curved portion with respect to an extension region of a character line, and a first parallel portion is formed to the same depth as the drawn depth of a second parallel portion. In the second drawing step, a second inside curved portion having a greater curvature than a first inside curved portion is formed.

Press forming method

The present invention is a press forming method for obtaining a target formed article that has an edge-shaped ridge section and that has a negative surface on one side and a positive surface on the other side with respect to the ridge section as a border, said press forming method including: a first step for forming an intermediate formed article having an intermediate ridge section having a larger radius than the edge radius of the ridge section; and a second step for forming the target formed article from the intermediate formed article. The intermediate formed article has a first intermediate positive surface that corresponds to the site extending from the ridge section to the negative surface of the target formed article and also has a second intermediate positive surface that corresponds to the site extending from the ridge section to the positive surface of the target formed article and that continues from the first intermediate positive surface and an intermediate negative surface continuing from the second intermediate positive surface.

A recording and/or reproducing apparatus has a disk transfer mechanism, a mechanical chassis lifting/lowering mechanism, and a gear switching mechanism. The disk transfer mechanism transfers a disk onto a disk table with a motor. The disk transfer mechanism has a rotation transmitting assembly having a gear train including a swing gear and another gear. The mechanical chassis lifting/lowering mechanism lifts and lowers a mechanical chassis with respect to the disk, which is transferred onto the disk table by the disk transfer mechanism. The gear switching mechanism brings the swing gear out of mesh with the other gear of the gear train after the disk is transferred onto the disk table by the disk transfer mechanism, thereby preventing the disk transfer mechanism from being actuated by the motor, and actuating the mechanical chassis lifting/lowering mechanism with the motor. After the disk is transferred onto the disk table by the disk transfer mechanism, the motor having actuated the disk transfer mechanism actuates the mechanical chassis lifting/lowering mechanism.

A plurality of supporting portionsinclines with respect to a top portionas a vertex. A trayis formed into a substantially triangular pyramid (three-dimensional) configuration, and a planar dimension of the traycan be smaller than that of a conventional turntable. Accordingly, a plurality of disks can be mounted on the tray. The supporting portionof the traycan be placed in parallel to a door leaf without a slide mechanism that has conventionally been used for sliding a tray. Accordingly, a desired disk can be attached/detached merely by rotating and driving the tray, and a mechanism disposed at a stereo apparatus is made compact and manufactured inexpensively.
