Title: Optical recording device
Inventor: YAMAGUCHI SHOJI
IPC: G11B7/08
Filed: 1990-10-31
Abstract: PURPOSE:To prevent that an optical head and an optical recording medium are run while they are being brought into contact with each other by a method wherein, before the optical recording medium stops turning, a movable body is housed in a housing member. CONSTITUTION:The following are provided: a movable body 3 which is moved while it is guided by a guide member installed along the radial direction of an optical recording medium 2 which is turned; and an optical head 5 which is levitated and moved by an air current caused when the optical recording medium 2 is turned. A guide member is arranged and installed so as to be extended toward the outside from the outer circumferential end of the optical recording medium 2. In addition, a housing member 7 which houses the moved and scanned movable body 3 in this part when the optical recording medium 2 stops turning and which is provided with a head contact face to and with which the optical head 5 of the movable body 3 is slid and brought into contact is installed in a position corresponding to the guide member. A displacement means 9 is attached to the housing member 7 and displaces the head contact face to a direction which does not prevent the movable body 3 from being advanced and retreated when the movable body 3 is housed or sent out. Thereby, it is possible to prevent that the optical head and the optical recording medium are run while they are being brought into contact with each other immediately after the optical recording medium has started turning or immediately after it has finished turning.

Inventor: KOGA TAKATOSHI
IPC: G06F13/38
Filed: 1985-12-25
Abstract: PURPOSE:To eliminate the need for a complicated program by executing, based upon the value of the second RSF/F, whether the supply prohibiting control to an 8-bit shift register is executed for the clock inputted from a shift clock input terminal by an external input terminal or by the 1st RSF/F. CONSTITUTION:By using the inverse of EN terminal 11 as a shift clock supplying prohibiting signal, the action to fetch 8-bit data desired out of the continuous serial data which needs the complicated program in the conventional technology can be controlled only by impressing 'low' to the inverse of EN terminal only in the desired 8-bit data input. Thus, not only the conventional complicated program is not necessary, but also it is not necessary to also think the timing in the complicated program and with a simple control, the serial data can be read.
