摘要： PURPOSE:To prevent the exhaustion of printing paper on the way of printing and to minimize the wastefulness of the paper when continuous printing paper is used in a calculator system equipped with a printer. CONSTITUTION:Prior to performing the printing of printing data 31, a printing paper use quantity calculating means 12 calculates the quantity of printing paper becoming necessary at the time of the printing of the printing data 31 and a judging means 15 judges whether the exhaustion of the printing paper is generated when the printing of the printing data 31 is performed on the basis of the quantity of the printing paper calculated by the printing paper use quantity calculating means 12 and the residual quantity of the printing paper of a printer 2 held to a residual printing paper quantity holding means 14. A printing control part 17 outputs the printing data 31 to the printer 2 only when the exhaustion of the printing paper is judged to be not generated by the judging means 15 and a paper deficiency information means 18 displays the information of paper deficiency on a CRT 6 when the exhaustion of the printing paper is judged to be generated by the judging means 15 to issue a command for an operator to supply and replace the printing paper.

摘要： PURPOSE:To shorten the data reading time by calculating the moving distance of the data reading part of an auxiliary memory for each data storing position and reading the data stored in the storing position having the minimum distance. CONSTITUTION:A storing position calculation means 1 calculates (A1-A3) the storing positions of an auxiliary memory for the data to be referred to for each data stored in multiple. A data reading part-data storing position distance calculation means 2 calculates the distance between a data reading part and a data storing position for each data stored in multiple based on the position H of the data reading part stored previously in a main memory and the data storing position calculated by the means 1. Then the data having the minimum distance between the data reading part and the data storing position is read and a data reading part position calculation part 3 calculates a new data read ing part position and stores it in the main memory. Thus the data reading time is shortened.

摘要： PURPOSE:To execute the processing at a high speed by calculating a distance in which a data writing part moves at every combination of a write sequence of data at the time of writing the data which is stored in multiple on an auxiliary storage and executing write of the data in the sequence in which the distance becomes the shortest. CONSTITUTION:It is assumed that data d1 is written in positions 101-103 on an auxiliary storage device 10, and a position of the present data writing part is denoted as 100. A combination of write sequence of the data in this case consists of six kinds of positions 101 102 103, positions 101 103 102, positions 102 101 103, positions 102 103 101, positions 103 101 102, and positions 103 102 101. In this case, the sequence of the positions 103 102 101 becomes the shortest. Therefore, write of the data d1 is executed by the sequence of the positions 103 102 101, and the data writing part moves by a distance shown by a distance M1+M2+M3. In such a way, the processing can be executed at a high speed.

摘要： PURPOSE:To prevent wasteful printing being performed by comparing the abrasion degree of a printing type normally printable by a printer with that of the printing type after printing when printing data is sent out to the printer. CONSTITUTION:A printing possibility judge means 3 compares the limit abrasion degree of each printing type normally printable by a printer 4 stored in a printing type limit abrasion degree table 7 with the abrasion degree of each printing type after printing stored in a printing type abrasion degree table 6 calculated by a printing type abrasion degree calculation means 2 to judge whether printing data ready to print presently is normally printable with respect to all of printing types and monitors the normality of printing. The printing possibility judge means 3 permits the sending out of printing data to the printer 4 when the printing data ready to print presently is normally printable with respect to all of the printing types but does not permit the sending-out of the printing data to the printer when the printing data is not normally printable even with respect to a part of the printing types.

摘要： PURPOSE:To prevent the blurring of printed characters or the like from occurring due to deficiency of an ink, by obtaining the cumulative consumption of a printing ink by summing up the consumption of the ink upon completion of the preceding printing operation and the consumption of the ink necessary for printing data to be printed this time, and comparing the cumulative consumption with a preset threshold. CONSTITUTION:When an instruction to print printing data 4a prepared in a storage device 4 is given, an ink consumption calculating means 6 calculates a total consumption CD of a printing ink necessary for the printing, and a cumulative ink consumption calculating means 7 adds the consumption OD of the ink upon completion of the preceding printing operation to the consumption CD of the ink for this-time printing operation, thereby calculating the total ink consumption ND upon the completion of printing of printing data to be printed this time. A judging means 8 as to whether printing can be performed compares the total ink consumption ND with a threshold TD preset as a maximum ink consumption with which normal printing free of blurring or the like can be performed, and when ND TD, it is judged that printing can not be performed. When it is judged that printing can be performed, a printer-controlling part 3 controls a printer 1 to print the printing data, whereas when it is judged that printing can not be performed, printing is not conducted, and a signal 8a indicating that printing can not be performed is outputted to the exterior.

摘要： PURPOSE:To shorten a time required for the reference of a data, by comparing the distance to be moved of the data reading part (head) of respective auxiliary memory device at the time of referring the data stored in multiplex in plural sets of auxiliary memory devices, and selecting the auxiliary memory device wit the minimum distance. CONSTITUTION:A storing position calculating means 1 calculates the storing position of the data to be referred on the auxiliary memory device at every auxiliary memory device, and an inter-data reading part (head) and data storing position distance calculating means 2 calculates the distance between the data reading part and the storing position from the position of the data reading part (head) stored in a main storage in advance and the storing position of the data calculated by the storing position calculating means 1. And after the data is referred to the content of the auxiliary memory device with the minimum distance between the data reading part (head) and the data storing position, a data reading part (head) position calculation means 3 calculates the new position of the data reading part (head), and stores it in the main storage. In such a way, it is possible to execute the reference of the data within a short time.

摘要： PURPOSE:To early recover the abnormality of a control memory by storing a microprogram stored in the control memory also in a main memory and transferring the microprogram from the main memory when the control memory has abnormality. CONSTITUTION:An information processor 100 stores a microprogram in a control memory 102 from an external memory device 101 in a rise mode. When a setting action is over, the contents of the memory 102 are written to a memory module 201 of a memory device 200. The processor 100 reads the microprogram out of the memory 102 and sends it an instruction decoding part 103. Then the decoded information controls the processor 100 to perform the processing. The normalness of the microprogram is checked by the memory 102 and the abnormality is detected. In such a case, the subsequent control is discontinued and the microprogram stored in a specific address of the device 200 is read out and written to the memory 102 if said checked microprogram is broken. Then the contents of the memory 102 are replaced. Thus the memory 102 is early restored.
