Title: Optical deflector
Inventor: SETO MASANORI
IPC: G02B26/12
Filed: 1995-01-20
Abstract: PURPOSE: To provide an optical deflector constituted to prevent the heat generated from a driving section from being transferred to a revolving shaft and bearing, to attenuate the transmission of the vibration generated by rotation of a rotating body and to prevent an optical unit packaged in a box from being affected by the vibration. CONSTITUTION: A motor housing 21 supports windings 24, an iron core 25, etc., and functions as a mounting flange to the optical box 5. The ball bearing 26 turnably supports the rotating body. A cylindrical sleeve 30 is lower in thermal conductivity and transmittance of the vibration as compared with the housing 21 and is disposed between the housing 21 and the bearing 26. The cylindrical sleeve 30 insulates the heat generated in the windings 24 according to the constitution described above and, therefore, the heat is not transmitted to the bearing 26 and the deterioration and run-out of the lubricating oil of the bearing 26 are prevented. Since the cylindrical sleeve 30 attenuates the transmission of the vibration, the vibration from the bearing 26 is not transmitted to the housing 21 and the optical box and the vibration of the optical unit is prevented.

Title: Digital-analog converter
Inventor: KAJITANI MASANORI
IPC: H03M1/68
Filed: 1985-02-12
Abstract: PURPOSE:To decrease high frequency distortion by designing the converter that two potentials are alternated once or over during one converting period without fail so as to suppress a high frequency spectrum at a low frequency in any case. CONSTITUTION:Voltages V1, V2 are obtained from a D/A converting circuit 1 in response to input data a4-a11 in high-order 8-bit. The V1 and V2 have a potential difference twice the minimum potential difference eM (eM is voltage division being (Vref-VE)/(2<8>+2) by a voltage division circuit 12). On the other hand, a signal in response to data a0-a3 of low-order 4-bit where the 3rd bit from the low-order is logical 1 and the other bits are all logical 0 by an adder circuit 21 is outputted from a pulse forming circuit 24 in a D/A converter circuit 2. The said output signal is inputted to a selection synthesis means 25, from which the V1, V2 are outputted alternately. In this case, since the mean level between the V1 and V2 in one converting period uses 2<5> clock pulse count number, the effect of the said data fed by the adder circuit 21 is lost and the mean level in response to the data a0-a3 is obtained.

Title: Inhibiting mechanism for movement of original platen of copying machine
Inventor: KURATA MITSURU
IPC: G03B27/62
Filed: 1984-02-16
Abstract: PURPOSE:To inhibit the original platen from moving unpreparedly through simple constitution by providing a stopper which engages and disengages elastically from a driving arm for coupling the original platen with its endless driving means operatively. CONSTITUTION:The original platen 1 at its stop position can not be moved because a driving arm 7 abuts on the projection 12a of a stopper 12 for leftward movement and abuts on a pin 11 provided to a chain 9 for leftward movement. When the chain 9 is run as shown by an arrow A for copying operation, a projection part 16 provided thereto abuts on the projection 12b of the stopper 12, which is then rotated clockwise. The arm 7 starts moving forth as shown by an arrow A after moving right. In this case, the arm 7 presses down the projection 12a, so the stopper 12 causes no hindrance to the run of the original platen 1. The stopper 12 is pressed down with a knob 12e so as to move the platen 1 during the stop of the copying machine. This simple constitution prevent the unexpected movement of the platen.
