In a safety stock control system, safety stock is changed in response to updating of a setting value so as to be continuously maintained as a proper value. The safety stock control system is comprised of a demand prediction means, an actual value calculating means, a predicted remainder calculating means, a parameter calculating means, and a safety stock calculating means for calculating safety stock based upon a parameter calculated by the parameter calculating means. In response to updating of the setting value, data of an area, which is different from such a data read when a plan is made, is temporarily read from a data storage means to the respective means, and then, various sorts of calculating process operations are carried out either one time or plural times.

A production plan is created so as to minimize risk of demand variations. Forecasted values of amounts of requests are entered for each different item of products, markets, dates, past accuracy of demand forecasts, and order achievements at the time when the plan is created. Scenario information is created in which assumable amounts of request for each different item of the products, markets, and dates and probabilities at which the amounts of requests agree with actual amounts of requests are defined. Management indexes are found from the amount of stockout and amount of stock calculated in each different scenario, based on the scenario information, target values of the management indexes, and information on strongpoints. An amount of production that maximizes the achievement ratios of the management ratios to their targets within the ranges of supplied materials and within the range of the production capacity is calculated by an optimization algorithm.

Fee imposition system and method for application software, in which a software providing corporation can collect the fee without fail and charge a fair fee to a customer, and thereby the customer can use the application software with a paying method easy to estimate. The fee imposition system includes a server machine installed in a management center for managing the software, a client machine installed in a customer's office and connected with the server machine through a communication means, a ticket issue unit for issuing a ticket file on the basis of a predetermined fee schedule, and a data copy/writing unit for copying data corresponding to the information designated by the ticket file from a data source memory unit and recording the copied data on a data target memory unit.

Fee imposition system for application software

A scanner head cartridge is constituted by a lower case which houses optical parts required for reading and electrical parts required for image processing, and an upper case which can engage with the lower case to cover the open surface of the lower case, and a positioning guide means used upon inserting the cartridge into the carriage is formed on the surface of the upper case, that is opposite to the lower case. A scanner head cartridge is held on a carriage that moves an ink head cartridge of an ink-jet printer for performing recording on a recording medium, in place of the ink head cartridge, and can be commonly used using a common base unit even in carriages which mount different ink head cartridges and have different shapes. In addition, the scanner head cartridge allows easy adjustment of the optical system.

Scanner cartridge and information processing apparatus

A printing apparatus and method therefor reduces power-source capacity of the apparatus imposing any load on the printing apparatus and varying its printing speed. In parallel to printing operation, the number of print dots is counted by using a counter, and information amount for calculating the scanning period for each scanning is measured by also using a counter. Then, at the completion of each scanning, a print-duty ratio is calculated from the number of print dots and the information amount for calculating the scanning period for each scanning, and a waiting period to delay starting of the next scanning is set, based on the calculated duty ratio.

Printing apparatus and driving method therefor

A scanner head cartridge, which can be mounted exchangeably with an ink head cartridge on a carriage capable of moving the ink head cartridge of an information processing apparatus for recording on a recording medium, includes a lower case containing therein optical parts required for reading, an upper case structured to be coupled with the lower case for covering the open face of the lower case and guiding means arranged on the upper surface of the upper case for positioning when being inserted into the carriage. With the structure thus arranged, it is possible to mount the scanner head cartridge on the carriage by a simple mounting operation with a highly precise positioning simultaneously.

Scanner head cartridge and apparatus for processing information capable

In a printing apparatus of the type in which a printing head is detachable to a carriage, a detecting circuit is provided for detecting whether or not a printing head 8 is mounted on a carriage. A CPU 2 included in the printing apparatus supervises the output of the detecting circuit at every predetermined time interval. When determined the printing head 8 is not mounted, the supplement of the driving voltage for the printing head 8 is suspended.

Printing apparatus

A printer has an electric power supply controller which controls electric power supplied to an indicator indicating a state of the printer so as to prolong a driving time of the printer, which is driven by a battery. When the apparatus is set to an on-line state using an on-line key, electric power is initially supplied to an on-line LED, which indicates the apparatus is in the on-line state. Afterwards, when a predetermined time period has passed, the supply of electric power is cut off to the on-line LED, whereby the consumption of electric power supplied to the indicator can be minimized.

A battery-driven recording apparatus records a plurality of lines by recording-scan by using a recording head having a plurality of recording elements. A capacity of a battery is detected, and when the capacity of the battery is lowered, the number of lines to be recorded in one recording scan is reduced.

Recording apparatus for controlling recording in accordance with battery

A printing apparatus is capable of being driven by a battery for an extended period of time without using a battery having a large capacity, and the battery is capable of being charged while the occurrence of the memory effect is suppressed. Also provided is a method of charging the battery in this apparatus. Battery capacity is detected in the driving interval of a carriage motor and/or conveyance motor. When the battery capacity falls below a predetermined value, control is performed in such a manner that the driving intervals of the carriage motor and conveyance motor will not overlap. When charging of the battery is designated, the battery is discharged using a current load in the apparatus, after which the battery is charged.

Printing apparatus and method of charging battery therein

A control signal is outputted from a CPU in a predetermined period to a one-shot circuit. An output signal of the one-shot circuit is maintained at a predetermined level, as far as the control signal is supplied to the one-shot circuit in the predetermined period. The output signal of the one-shot circuit is applied to a charging circuit for a battery. The charging circuit performs a charge operation for the battery while a predetermined level of the output signal of the one-shot circuit being kept on.
