Title: Camera
Inventor: ITO KAZUYA
IPC: G03B7/099
Filed: 1995-06-20
Abstract: PURPOSE: To provide a camera miniaturized further by constituting the optical system of an infrared active range-finding device and a photometric optical system so that their optical paths may be partially shared. CONSTITUTION: The photometric optical system and a range-finding optical system used in this camera are constituted so that their optical paths may be partially shared by providing an optical system 10. Since a cold mirror is used for an optical path dividing surface 2, an incident light beam is divided into infrared light and visible light, and only the infrared light is guided to a range-finding element 5 and only the visible light is guided to a photometric element 7. Therefore, the utilization efficiency of the incident light beam guided to the respective elements is improved. Furthermore, a visible light cut filter and an infrared light cut filter need not be arranged in front of the elements 5 and 7, respectively, whereby the photometric and the range-finding optical systems are miniaturized.

Title: Printer
Inventor: YAGI TAKASHI
IPC: B41J25/308
Filed: 1980-10-31
Abstract: PURPOSE: To prevent a printing head and a ribbon guide from interfering with a printing ribbon and recording papers, etc., by providing the tip of the printing head with a ribbon guide which is capable of holding the printing ribbon and the printing head in such a position as to keep them facing to each other and slide them freely.  
     CONSTITUTION: In the case of printing letters on such papers as a receipt and a journal, etc., a printing head 21 is kept opposite to a platen 28a on one side. At first, when a drive shaft 2 is turned by driving a motor 10, a carrier frame 1 is moved along the platen 28a and a platen 28b, and during this period, a command for printing is given to the printing head 21, and printing is executed. As a chip 14 cuts off the light axis of a photocoupler 13 by shifting of the carrier frame 1, a reset pulse is emitted whereby the motor 10 is stopped. Other operation commanding signals, such as those for feeding of the papers, turning of the printing head 21 toward the platen 28b and reversing of the motor 10 for shifting the carrier frame 1 in the opposite direction, etc., are also emitted at the same time.

Title: Correction system for coding error
Inventor: NISHIMURA KEIZOU
IPC: H04L1/00
Filed: 1981-09-30
Abstract: PURPOSE:To suppress the generation of erroneous words which can not be corrected by a correcting operation, by counting the number of coding error flags added with a data word, comparing the number with a prescribed number and controlling the error correction operation. CONSTITUTION:An eraser flag added to a word in a block consisting of a data work group and a parity word group is inputted from a terminal 1 to a shift register 4 via a counter 2 and a multiplexer 3. The number of flags in a block counted at the counter 2 is decoded at a decoder 5 depending whether it is 0 or 1 and outputted to a controller CT6. The CT6 controls a detection correction operating circuit 7, the circuit 7 sequentially checks each word and when an erroneous word to be corrected exists, a correction pulse is outputted to the  CT6. When the value of the counter 2 is 0, the CT6 outputs the correction pulse  to a terminal 9. When no correction pulse is outputted from the circuit 7, the  CT6 gives the 2nd erase flag to all words in the register 4 and outputs the result from a terminal 10.
