Publication number: 20020052735Abstract: A sound reproduction apparatus includes a digital memory and a specified reproduced frame number decoding section. The digital memory stores audio data such as MP3 data. The specified reproduced frame number decoding section decodes specified frames and outputs reproduced sound. The sound reproduction apparatus further includes a reproduced frame number setting section and a skipped frame number setting section that contain a reproduced frame number and a skipped frame number, respectively. When a fast forward/reverse instruction section instructs the fast forward, the specified reproduced frame number decoding section decodes only the reproduced frames and outputs reproduced sound at a higher speed than a normal speed. The sound reproduction apparatus can freely change the reproduced frame number and skipped frame number, and hence can vary the speed of the fast forward.Type: ApplicationFiled: December 21, 2001Publication date: May 2, 2002Inventors: Soichi Nagano, Kenji Miyashita, Takahisa Aoyagi

Patent number: 6059286Abstract: First bearing position 22 and second bearing position 23 are formed on bearing member 14 that supports rotational shaft 32 of driving conveyance roller 12 while being subjected to pressure from bearing spring 15. Normally, rotational shaft 32 is supported by first bearing position 22, and driving conveyance roller 12 is kept in pressure contact with the driven conveyance roller via the force from bearing spring 15. Conveyance of sheets is performed in this state. When the apparatus is stopped due to a paper jam and the user pulls out the jammed sheet, the force of the pulling causes rotational shaft 32 to detach from first bearing position 22 and move to second bearing position 23 and driving conveyance roller 12 loses pressure contact with the driven conveyance roller. Therefore, the sheet may be easily pulled out, and the apparatus may be reset for continued use.Type: GrantFiled: February 5, 1998Date of Patent: May 9, 2000Assignee: Minolta, Co., Ltd.Inventor: Kenji Miyashita
