IPC: G03G15/00
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To improve the quality of a recording image by fitting a removal means for removing foreign matter on a document onto a document conveyance route leading to a reading position for removing foreign matter on the document before reading an image. SOLUTION: At the time of reading the images of moving documents on a document feed tray, the documents are separated one by one by separating rollers 35, 36, and are conveyed so as to pass over a light transmitting plate 23 along a document conveyance route 41 running along guide plates 38, 39. The image on the document is read on the light transmitting plate 23. While the document is passing through the document conveyance route 41, foreign matter such as dust adhering to the surface to be read of the document is dropped off into a recessed part 40. Storage of the foreign matter into the recessed part 40 is carried out by dropping it off directly into the recessed part 40 or dropping it off before it reaches the recessed part 40 and guiding it into the recessed part 40 along a guide plate 39.  As a result, foreign matter such as dust on the moving document is removed, therefore, it is possible to improve image quality.

Title: Clock synchronizing circuit
Inventor: OSAWA TOMOYOSHI
IPC: H04L7/02
Filed: 1986-02-04
Abstract: PURPOSE:To attain clock synchronization without receiving reference data by providing an initial phase difference estimation device. CONSTITUTION:N samples of transmission data at an interval Tb are sampled at an interval Ts, when it is supposed that the time difference between the sample point of time at the N-th sampling and that of a demodulation data is psi, then the initial clock phase difference (that is, the time difference between the 1st sample point of time and the 1st demodulation data )phi is expressed as phi=modTb(N.Ts+Y), where modx(y) in an equation is the modulo representing the remainder when a function (y) is divided by a function (x). Since N, Ts and Tb are known and the time difference psi is the time difference from the input of the N-th sample till the demodulation time, it is obtained simply. The section executing the said operation is the initial phase difference estimation device 5. Thus, the phase in the 1st step is continuous to that in the 2nd step after the changeover of the switch 4 by changing the phase of the interpolation filter by a control circuit 6 so as to compensate the phase difference calculated according to the equation at the demodulation data output after the changeover of the switch 4 and the transmission data matching with the clock phase is demodulated completely.

Abstract: PURPOSE:To enable exact sensing of a rise action of pantograph by forming an optical loop whose reflective surface is a rotating shaft causing said pantograph to rise and fall. CONSTITUTION:When a pantograph 1 is lowered, the light from a light emitting diode 17a within a rise sensor 17 is guided through optical cable 15a, collimator 16a, surface of main shaft A with low reflectance, collimator 16b and optical cable 15b and an incident light to a photosensor 17b is in dark state. On the other hand, if a frame 5 of said pantograph 1 rises by a turning force of main shafts A, B, a reflector piece 14 turns with turning of the main shaft A and reflected light from the collimator 16a comes to be reflected by a reflector piece 14 with high reflectance. Accordingly, said incident light to the photosensor 17b shifts from dark state to light state.

Filed: 1993-01-19
Abstract: PURPOSE:To easily arrange the slave screen and message display position of PinP in an effective screen at a low cost by using a vertical blanking signal as a reference signal for position setting. CONSTITUTION:When reference pulses determining the positions of the slave screen and a display of a message are detected on the basis of the rising of the pulses, inverted vertical blanking pulses are used as the reference signal for position setting on condition that the slave screen, etc., are displayed at the upper part on the screen of a CRT (For example, the position of the slave screen PU is left upper.). Consequently, even when the display position is still on a 20th line, the slave screen, etc., are displayed within the effective screen 10S of the CRT. Further, when the slave screen, etc., are displayed at a lower position on the screen of the CRT (For example, the position of the slave screen PD is left lower.), on the other hand, the vertical blanking pulses are used as the position setting reference signal. Consequently, even when the display position is still on a 160th line, the slave screen, etc., are displayed within the effective screen 10S of the CRT.
