Title: Original reader
Inventor: IKEDA YOSHINORI
IPC: H04N1/107
Filed: 1984-09-25
Abstract: PURPOSE:To prevent the throughput from dropping irrespective of the placed state of an original by recognizing the original placed state on an original platen and controlling the original scan start position or original scan termina tion position. CONSTITUTION:An original platen 136 where an original 40 is placed is preliminarily scanned by an exposure scan stand prior to an original read action. At such a time, a reflecting plate for reflecting totally incident light is fitted on the interior of an original cover, and the original is colored except black and white colors. Accordingly the original cover can be distinguished from the original 40. As a result, head coordinates X1 and end coordinates X2 of the original 40 can be detected by the preliminary scan. After the end coordinates X2 are detected, the exposure scan stand terminates the preliminary scan and is returned to a top part (c) of the original 40. Afterward only the section between coordinates X1 and X2 is scanned by prescribed times to terminate the original scan, and the exposure scan stand is returned to a scan start position (g).

Title: Data transfer method, data transmitter and receiver
Inventor: TSUZUKI CHIKAU
IPC: H04B7/24
Filed: 1993-07-19
Abstract: PURPOSE:To reduce overhead caused by searching a communication enable channel every time with data transfer or waiting time until radio waves to be transmitted get stable in the case of transmission with a simplex communication system using packets. CONSTITUTION:In the case of transmission, a state code SC and a code EC for error detection are added to print data and defined as a packet and the plural packets are continuously transmitted. On the reception side to receive these packets, concerning each packet, it is detected by using the code for error detection whether the data are normally transferred or not. When the presence of any error is judged, code NAK is returned, and the transmission side retransmits the data of the packet where the error is found out. Since it is not necessary to repeatedly search the idle channel for each packet, transfer speed is not decelerated. Further, by increasing/decreasing the size of the packet corresponding to the frequency of error generation, best transfer efficiency can be provided.

IPC: G10L19/00
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To reduce noise component by smoothing only digital data discriminated to be noise data in the case of bit length extension. SOLUTION: A difference detection section 1 takes a difference between a sample this time and a sample at a preceding time when input N-bit digital data are sampled and the result is given to a pattern detection section 2. When the detection section 2 discriminates noise data, the section 2 provides an output of coefficient information to a smoothing section 3, output information to a storage section 4 and delay information to a delay section 5. The coefficient information is a coefficient used to smooth the noise data, the delay information is number of samples required to detect noise data by the detection section 2 and the smoothing section 3 delays the input data by the ample number at bit length extension processing to correct the time for accurate extension processing.  Then the smoothing section 3 calculates the digital data from the delay section 5, based on the coefficient information outputted from the detection section 2 to conduct bit length extension processing and smoothes the noise data thereby reducing a level of the noise data signal.
