Title: Filter circuit for data reception
Inventor: YOSHIZAWA SHIGEO
IPC: H03H11/12
Filed: 1990-01-10
Abstract: PURPOSE:To facilitate a base band process including a noise state by detecting a preamble signal, and then varying the in-band ripple of a base-band filter and varying the in-band gain. CONSTITUTION:When the output of a comparing circuit 110 is a preamble signal with a predetermined bit rate, a preamble signal detecting circuit 111 detects it and a switch 112 is controlled with its output. The switch 112 is in the OFF state until the preamble signal is detected and turned on when the preamble signal is detected. When the switch 112 is in the ON state, this circuit operates as a normal tertiary LPF, but when the switch 112 is in the OFF state, the ripple in the band increases, so that the gain nearby a cutoff frequency increases. Consequently, the passing band gain is high in a period from the noise state at the stop of transmission to the preamble signal detection and noise detection in the base band behind the comparing circuit 110 is easy; and in-passing-band group delay characteristics become stable after the preamble signal detection and the filter which is free from inter-code interference is obtained.

Filed: 1983-01-12
Abstract: PURPOSE:To accurately find out the time of exchange of recording paper, by counting drive pulses for a pulse motor for sending out the recording paper, to exactly detect the remaining quantity of the paper. CONSTITUTION:Drive pulses from a drive control section 40, which correspond to the sent-out quantity of recording paper, are applied to a counter circuit 50 to count the drive pulses to detect the sent-out quantity of the paper.

Therefore, the latest counted value is always stored in the memory 60. The value indicating the latest used quantity of the recording paper is applied to an indicating section 70 and subtracted from a value corresponding to the preset initial quantity of the paper, to show its remaining quantity. The operating person can thus be informed of the remaining quantity of the recording paper.

Title: Document reading and transporting apparatus
Inventor: SANNOMIYA AKIO
IPC: B65H5/06
Filed: 1981-01-13
Abstract: PURPOSE: To shorten the processing time by reducing the speed of a motor drive of a transport apparatus for an optical character reader from the time when a detector detects the leading end of a document until the completion of reading and the detection of trailing end of the document are accomplished, and stopping the drive of taking out.  
     CONSTITUTION: When a detector detects the leading edge of a document which is taken out and transported by a transport mechanism, a motor is stopped for a fixed time so that the document is stopped before a reading portion. Subsequently, the motor is intermittently driven at a low speed, and the document reaches the reading portion to be read. When the detector detects the trailing edge of the preceeding document during reading, a signal of a reading mechanism has priority and the motor is driven at a low speed until reading is completed. If the reading is completed before the trailing end of the document is detected, on detecting the trailing edge, the motor is changed to high-speed driving. Since the motor driving is such controlled, the processing time can be shortended so as to assuredly take out the document.
