Title: Image-recording apparatus and facsimile apparatus using the apparatus and method for inspecting ink discharge
Inventor: IMAI TAKASHI
IPC: B41J2/175
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To detect even a discharge failure at a part of a nozzle array of a recording head in a detection operation for a quantity of ink remaining. SOLUTION: In the facsimile apparatus having a recording part which records by discharging ink to a recording medium from a recording head 5 equipped with a nozzle array 5c of a plurality of ink discharge nozzles, a photosensor is set with a lightemitting element 81 and a light-detecting element 82 disposed so that an optical axis is a predetermined angle to the nozzle array of the recording head 5. An ink discharge detection signal is generated at a change of an output of the photosensor when the discharged ink from the recording head traverses the optical axis. The presence/absence of an ink discharge, that is, whether the ink is discharged is inspected accordingly. The ink is discharged at a time point when the recording head 5 is located at each of discharge positions (1)-(n), and the ink discharge is detected by the photosensor.  The ink discharge at each part of the nozzle array is inspected in this manner.

Title: Memory destruction verifying system
Inventor: MAEJIMA YUKITO
IPC: G06F12/16
Filed: 1982-12-22
Abstract: PURPOSE:To discriminate the presence of destruction of program data of a main memory quickly by verifying destruction of program or data of the main memory using a cyclic code generating device. CONSTITUTION:When loading an initial program, a central controlling unit 1 transfers programs and data stored in an auxiliary memory 4 to the main memory 3. Then, the unit gives command to the cyclic (CRC) code generating device 2 to generate CRC code generation starting address and size of programs and data of unchanged contents to generate CRC code input data. The CRC code generating device 2 generates and stores CRC code. When it is necessary to check programs and data stored in the main memory 3, the central controlling unit 1 gives the same starting address and size to the CRC code generating device 2 as input data, and indicates the generation of CRC code. The CRC code is collated with the result generated at the time of initial program loading, and if they coincide, it is discriminated that there is no destruction of memory.
