摘要： PURPOSE: To improve the lifting of an arm with the fingers when a recording paper is replaced, to facilitate the replacement of the recording paper and to make it possible to record the measured value with the warping of the recording paper caused by moisture being corrected by providing a pen lifting member for separating a pen from the recording paper in the vicinity of the outer surface of the recording paper. CONSTITUTION: A pen lifting member 1 having a slant part 1a and a recording paper guide 1b is fixed to the vicinity of the outer surface of a recording paper 12. At the time of recording, the warping of the recording paper 12 is corrected with the recording paper guide 1b. When the replacement of the recording paper 12 is required, a pulse motor is rotated and an arm 16 is driven. A pen 15 is separated from the recording paper by utilizing the slant part 1a and stopped at the outside of the outer surface of the recording range of the recording paper 12. Under this state, the recording paper 12 can be replaced without lifting the arm 16 with the fingers. After the replacement, the recording paper is fixed with a recording-paper rotating shaft 13, and then the arm 16 is returned to the measuring state. The arm 16 is automatically slid and mounted on the pen lifting member 16, and the pen 15 is separated from the recording paper 12. Therefore, the pen 15 does not become the obstacle when the recording paper 12 is replaced, and the possibility of the deformation of the arm by external force becomes nil.

摘要： PURPOSE:To exchange easily a data with other device by providing a fixed bus opening period or a bus opening possible period for exchanging a data, in a period of a sequence program which makes the round in a fixed period. CONSTITUTION:Other computer device 1 and a sequence 11 are coupled by an external bus 10 through each bus interfaces 7, 19. A clock (CLK) supplies a clock signal to a central processing unit 12 of a sequencer 11, and also communication control signals 44-46 are generated by counting said clock signal by a bus opening signal circuit 21 extracted from a bus interface 19. The bus opening signal 45 among them stops the central processing device 12 for a fixed period (bus opening period) TC1 by a signal of said period in a cycle time in which a sequence program makes the round. Accordingly, in this period TC1, a memory 13 of the sequencer 11 side is subjected to access from other computer 1 side, and a data exchange is executed.

摘要： PURPOSE:To generate magnetic fluxes in the spacing between a cover and an objective lens so as to attract the magnetic powder tending to infilter and to prevent the infiltration thereof into the optical head by fixing and providing an annular permanent magnet having about the inside diameter coinciding with the diameter of a circular hole to a cover coaxially with the objective lens. CONSTITUTION:The optical head of the optical disk device disposed with the objective lens 2 coaxially in the circular hole part 31 provided on the cover 3 is provided with the annular permanent magnet 1 of the inside diameter not smaller than the diameter of the circular hole 31 by fixing this magnet coaxially with the objective lens 2. The lines of the magnetic fluxes 11 generate the effect to attract the magnetic powder by the magnetic force generated around the permanent magnet when the magnetic powder tends to infilter by passing the circular hole 31 of the spacing between the objective lens 2 and the cover 3. The magnetic infiltrating into such place is as very small as the powder is suspended in the air and, therefore, the magnetic powder moves easily toward the permanent magnet and is attracted by the magnet. The magnetic powder is captured by the permanent magnet 1 and is thereby prevented from infiltering the inside of the optical head even if the magnetic powder tends to infiltrate into the optical head in such a manner.

摘要： PURPOSE:To eliminate the influence of the offset component of track crossing signals to an optical pickup by providing a counter which measures the period between rising signals of binarization signals about the track crossing signals and another counter which measures the period between falling signals and alternately setting the counted values of the counters in a register, with the set values being used as the speed signal of the optical pickup. CONSTITUTION:A binarization means 1 which binarizes track crossing signals, a 1st interval counter 4 which is triggered at every rise of the binarization signals 1a of the means 1 and measures the period of the signals 1a, and 1 2nd interval counter 5 which is triggered at every fall of the signals 1a and measures the period of signals 1a are provided. The counted values of the counters 4 and 5 are alternately and successively selected just before the counters 4 and 5 are re-triggered and sent to a common storing means 7. Since the output of the storing means 7 is used as the speed data of an optical pickup, the optical pickup does not receive any influence from the offset component of the track crossing signals.
