Publication number: 20090185461Abstract: A medium transporting mechanism for transporting one of stacked media each of which has a hole is provided. A holder is provided on a movable transporting arm and holds the one of the media. A guide is provided in the transporting arm, the guide has a tapered surface that is inclined with respect to an axis of the guide. The tapered surface is configured to be brought into contact with an inner surface of the hole of the one of the media when the guide is inserted into the hole of the one of the media. The tapered surface includes a first surface on a tip end portion of the guide and a second surface on a base end portion of the guide. An inclined angle of the first surface with respect to the axis of the guide is greater than an inclined angle of the second surface with respect to the axis of the guide.Type: ApplicationFiled: January 16, 2009Publication date: July 23, 2009Applicant: Seiko Epson CorporationInventor: Hideki Kawakami

Publication number: 20090178066Abstract: A transport arm device for carrying at least one disc comprising a driving means, a sway control member, and a swaying mechanism is disclosed. The sway control member comprises a hole in substantial middle of the sway control member for receiving a portion of the driving means and two leaf springs extending up from two sides of the sway control member respectively. The swaying mechanism is capable of grabbing the discs. The swaying mechanism comprises a rotating connection for engaging with a suspension of the transport arm device, wherein the two leaf springs are contacted with the swaying mechanism. The sway control member is moved by the driving means so as to rotate the swaying mechanism along a rotary axis on the rotating connection, and the two leaf springs provide elasticity for the swaying mechanism rotating back.Type: ApplicationFiled: March 23, 2009Publication date: July 9, 2009Inventors: Ming-Hsun Liu, Chung Hsuan Tsai

Publication number: 20090175137Abstract: A standard reproduction model for ensuring real time reproducing on a disk-shaped information recording medium, includes a pickup (102) that reads the real time data from the information recording medium, a buffer memory (103) that temporarily stores the real time data read by the pickup, and a decoding module (104) that reads the real time data from the buffer memory (103) and processes the read real time data. An access time Tacc of the standard reproduction model is expressed by the following formula, Tacc=A·dN+Trev+B where dN is a difference in rotational speed of the disk-shaped information recording medium, Trev is a rotation waiting time at a target access position, A and B are constants.Type: ApplicationFiled: March 5, 2009Publication date: July 9, 2009Inventors: Shuichi Yoshida, Tatsushi Bannai, Yoshiho Gotoh, Takashi Kishimoto

Publication number: 20090086588Abstract: In a feedforward timing extractor for extracting timing information from a playback signal, a frequency ratio calculation section 2 calculates the ratio between the frequency of the playback signal and the frequency of the output clock of a frequency synthesizer 6 by utilizing a specific pattern and a specific pattern appearing interval in the playback signal. A control section 4 controls the frequency dividing rate of the frequency synthesizer 6 in such a manner that the frequency ratio calculated by the frequency ratio calculation section 2 has a set value. Thus, as compared with a case in which the output clock of the frequency synthesizer 6 is a high-frequency fixed-rate clock, it is not necessary to operate the digital circuits at high speeds. Consequently, even in cases where the playback frequency (the playback rate) of the signal changes with time, the decimation rate at which pulses of a fixed clock are eliminated is constant, thereby reducing power consumption.Type: ApplicationFiled: July 18, 2006Publication date: April 2, 2009Inventors: Kouji Okamoto, Akira Yamamoto, Hiroki Mouri
