Title: Colorant film forming material
Inventor: MARUYAMA SEIJI
IPC: B42D15/10
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To simply discriminate genuineness by changing the observation angle of a significant information image section of a recognizable first image section and a significant information image section of an unrecognizable second image section to convert a recognizable image into an unrecognizable image and the unrecognizable image into the recognizable image. SOLUTION: When a first image section 7 formed by combining a first significant information image section 9 utilizing only a brilliant ink with a background image section 8 utilizing the brilliant ink and a black ink is observed on an area other than a regular reflection ray area, three primary components are predominant by making the colors on the same level, and the first significant information image section 9 is not recognized on the image section, while when a significant image section is observed on a regular reflection ray area, brightness can be discriminated to recognize the significant information.  On a second image section 10 provided with a second significant information image section 12 and a second background image section 11, colors are different when observed on an area other than the regular reflection ray area to make it impossible to discriminate and recognize the background image section, The genuineness can be discriminated at a glance.

Filed: 1993-12-28
Abstract: PURPOSE:To obtain a management method for a storage part which stores data such as image information and voice information by managing the storage part as plural divisions. CONSTITUTION:An external system sends a division quantity setting command for a buffer memory, an input selection condition setting command for respective buffer divisions, and an output data selection condition setting command for the respective buffer divisions to a central processing part. For example, data of a CD-ROM disk which are outputted from a CD-ROM decoder 14 are stored in buffer divisions 54 to 56 according to data selection conditions of input data selection parts 51 to 53.

Filed: 1994-12-20
Abstract: PURPOSE: To efficiently conduct storage work of documents by making an image display based upon display settings when an error in reading retrieval information is generated. CONSTITUTION: If a bar code is not decoded normally owing to a stain of the document, information showing a failure in decoding is sent from a bar code reader 300 to a CPU 10. The CPU 10 once receiving it does not feed a next document stack on an original platen, so the storing operation is stopped temporarily at the point of time. At the same time, a display showing the failure in reading the bar code is made on a display 32. In this state, the CPU 10 indicates the start of a read scan on the bar code to a handy bar code reader 310 as a 2nd retrieval information read means. Therefore, an operator takes the original out of a paper discharge part and applies the handy bar code reader 310 to read the bar code.
