Inventor: WAKUI HIROMITSU
IPC: B41J29/46
Filed: 1992-09-07
Abstract: PURPOSE:To enable a signal processor to quickly and easily specify a faulty location on a signal processing substrate by adding a simple test circuit to the processor so that the processor can compare signal data with test pattern data. CONSTITUTION:When the mode of the substrate is switched from a picture to a test mode, the select signal SEL of a register 10 changes from, for example, L to H and is inputted to a multiplexer 16. Then the data of the multiplexer 16 are changed from picture data to test pattern data prepared by a CPU 12 and selected test pattern data are inputted to the logic circuit and memory of a picture processing substrate 18 through a CPU interface(I/F) 14. In addition, the data held by the registers of a plurality of gate arrays are returned to the CPU 12 as output response data through the I/F 14. Therefore, the CPU 12 judges whether or not the holding (response) data of each register of the substrate 18 are proper by comparing the data with the test pattern data and, by reading out abnormality of the data, specifies an abnormal location, namely, a defective gate array.
