Herein, any measurement processor 13a carries out the inspection of certain paper is handled.In addition, each sensor element 11 detected various data from certain paper have been supplied to measurement processor 13a, and are stored among the sensing data memory block 42c of internal RAM 42.

At first, the CPU nuclear 41 in the high-speed CPU 31 is implemented to handle, with the inside (step S1) of initialization high-speed CPU 31 based on the control program among the control program memory block 42a that is stored in internal RAM 42.Relevant therewith, the CPU nuclear 41 in the high-speed CPU 31 is judged handling procedure (step S2) among the handling procedure memory block 42b that will download to internal RAM 42 based on above-mentioned control program.Realize this point, judge that each program that comprises a plurality of command units at least is as the handling procedure that will download.Herein, with the handling procedure that will download of each handling procedure unit judges corresponding to each process.

But, when a handling procedure corresponding to a process had the size of data that can not comprise in the 42b of the handling procedure memory block of internal RAM 42, CPU nuclear 41 can judge that each program of separating is as the handling procedure that will download in a downloading process from a handling procedure corresponding to a process.In addition, when a plurality of handling procedures corresponding to a plurality of processes had the size of data that can comprise in the 42b of the handling procedure memory block of internal RAM 42, CPU nuclear 41 can be judged the handling procedure that will download corresponding to a plurality of handling procedures conducts of a plurality of processes in a downloading process.

When having determined the handling procedure that will download in judgement, the CPU of high-speed CPU 31 nuclear 41 is to low speed CPU 32 output download requests, request download handler (rewriteeing the request of handling procedure) (step S3).

The low speed CPU 32 that has received this download request carries out processing, downloads the corresponding handling procedure of described request (transmitting the process of handling procedure) with high-speed CPU 31.That is, received in the handling procedure of low speed CPU 32 from be stored in external ROM 33 of download request and optionally read the high-speed CPU 31 processing of request programs that to download.In case low speed CPU32 has read handling procedure, it with download handler in high-speed CPU 31.

When the request of low speed CPU 32 beginning handling procedures was downloaded, the handling procedure that high-speed CPU 31 will transmit (download) stored among the handling procedure memory block 42b of internal RAM 42 (step S4).At this moment, wipe data (executed handling procedure) among the handling procedure memory block 42b that is stored in internal RAM 42.That is, in step S4, rewrite the handling procedure among the handling procedure memory block 42b that is stored in internal RAM 42.

When entire process program that low speed CPU 32 downloads is stored among the handling procedure memory block 42b of internal RAM 42, i.e. (step S5 when finishing from low speed CPU 32 download handler, "Yes"), the CPU of high-speed CPU 31 nuclear 41 is downloaded the download of finishing to low speed CPU 32 output expressions and is finished notice (step S6).

In addition, when finishing the download of handling procedure, the CPU of high-speed CPU 31 nuclear 41 judges whether to obtain sensing data to be processed (step S7).Carry out described judgement, whether be stored among the sensing data memory block 42c of internal RAM 42 with the data of judging at least sensor element 11 that will be by the routine processes downloaded.Attention each measurement processor 13a herein is to each sensor element 11 ... the various data that detect from certain paper are implemented to handle.Therefore, can judge each sensor element 11 ... whether the various data that detect from certain paper are stored among the sensing data memory block 42c of internal RAM 42.

When top judgement is (a step 7 when having obtained sensing data to be processed, "Yes"), the CPU of high-speed CPU 31 nuclear 41 implements to be stored in the handling procedure among the handling procedure memory block 42b of internal RAM 42, is stored in the data (step S8) among the sensing data memory block 42c of internal RAM 42 with processing.In addition, the CPU of high-speed CPU 31 nuclear 41 result's (result) of execution being stored in the handling procedure among the handling procedure memory block 42b of internal RAM 42 stores among the result memory block 42d of internal RAM 42 (step S9).

When use was stored in finishing dealing with that handling procedure among the handling procedure memory block 42b of internal RAM 42 implements, the CPU nuclear 41 of high-speed CPU 31 judged whether to finish the processing (processing that all handling procedures will be carried out) (step S10) of whole series.Carry out described judgement, judge whether that for the sensing data among the sensing data memory block 42c that is stored in internal RAM 42 processing that all handling procedures will be carried out finishes.In other words, carry out above-mentioned judgement, judge whether to exist the handling procedure that to carry out subsequently.

When above-mentioned judgement is the processing of whole series (step S10 when having finished, "Yes"), the CPU of high-speed CPU 31 nuclear 41 is exported the information that the result in the result memory block 42d that is stored in internal RAM 42 has been distributed identifying information by shared storage 13b to CPU (central processing unit) 15.In addition, also by shared storage 13b to the data accumulation parts 14 output information of having distributed identifying information of the result in the result memory block 42d that is stored in internal RAM 42 wherein.

Notice that each measurement processor 13a handles each sensor element 11 detected various information from every paper herein.Therefore, if the sensing data among the sensing data memory block 42c that is stored in internal RAM 42 has been finished whole series of processes (step S10, "Yes"), be stored in the check result that result among the result memory block 42d of internal RAM 42 is a paper that identifying information is determined.

Therefore, in step S11, from measurement processor 13a, provide the check result of the paper that identifying information is determined by shared storage 13b to CPU (central processing unit) 15 and data accumulation parts 14.

In addition, if above-mentioned judgement is whole series of processes when not finishing, promptly, if above-mentioned judgement is to have the handling procedure (step 10 that will carry out subsequently, "No"), the CPU of high-speed CPU 31 nuclear 41 turns back to step S2, and the processing of implementation step S2 to S10 once more.In the case, the handling procedure that high-speed CPU 31 will be stored among the handling procedure memory block 42b of internal RAM 42 is rewritten as next handling procedure, and implements to handle according to next handling procedure.

At first, the CPU nuclear 141 in the high-speed CPU 131 is implemented to handle the inside of initialization high-speed CPU 131 (step S101) based on the control program among the control program memory block 142a that is stored in internal RAM 142.Relevant therewith, CPU nuclear 141 in the high-speed CPU 131 is exported download requests according to control program to low speed CPU 132, its expression is downloaded the handling procedure that is used for character zone detection processing and is handled as first, as the handling procedure (step S102) among the handling procedure memory block 42b that at first downloads to internal RAM 142 in a series of processing (determining the processing of classification destination).

The low speed CPU 132 that has received this download request carries out processing, and response is downloaded the handling procedure (process of transmission handling procedure) that is used for the character zone detection and handles from the request of high-speed CPU 131.That is, received optionally to read in the handling procedure of low speed CPU 132 from be stored in external ROM 133 of download request and be used for character zone and detect the handling procedure of handling.In case low speed CPU 132 has read handling procedure, it downloads to handling procedure in the high-speed CPU 131.

When low speed CPU 132 started the request that is used for the handling procedure that character zone detects and downloads, the handling procedure that high-speed CPU 131 will transmit (download) stored among the handling procedure memory block 142b of internal RAM 142 (step S103).

When the entire process program that is used for character zone detection processing of low speed CPU 132 downloads is stored in the handling procedure memory block 142b of internal RAM 142, i.e. (step S104 when finishing from low speed CPU 132 download handler, "Yes"), the CPU of high-speed CPU 131 nuclear 141 is downloaded the download of finishing to low speed CPU 132 output expressions and is finished notice (step S105).

In addition, when finishing the download that is used for the handling procedure that character zone detect to handle, the CPU nuclear 141 of high-speed CPU 131 judges whether to obtain the view data (step S106) on the mail to be processed.Make described judgement, judge whether the mail view data of being read by scanner 121 is stored among the sensing data memory block 142c of internal RAM 142.

When use was loaded in finishing dealing with that handling procedure among the handling procedure memory block 142b of internal RAM 142 implements, the CPU nuclear 141 of high-speed CPU 131 judged whether to finish the processing (processing that all handling procedures will be carried out) (step S109) of whole series.Make described judgement, judge whether that for the mail view data among the sensing data memory block 142c that is stored in internal RAM 142 processing that all handling procedures will be carried out finishes.In other words, make above-mentioned judgement, judge whether to exist the handling procedure that to carry out subsequently.

When above-mentioned judgement is the processing of whole series (step S109 when having finished, "Yes"), the CPU of high-speed CPU 131 nuclear 141 is to the information of control assembly 112 outputs to the distribution of the result among the result memory block 142d that is stored in internal RAM 142 identifying information (information of identification mail).

In addition, do not finish if above-mentioned judgement is whole series of processes, that is, if above-mentioned judgement is to have the handling procedure (step 109, "No") that will carry out subsequently, the CPU of high-speed CPU 131 nuclear 141 is judged the next handling procedure (step S111) that will download.Realize this point, judge that each program that comprises a plurality of command units at least is as the handling procedure that will download.Herein, according to the handling procedure that will download of each handling procedure unit judges corresponding to each process.

In addition, the same with above-mentioned first embodiment, when a handling procedure corresponding to a process had the size of data that can not comprise in the 142b of the handling procedure memory block of internal RAM 142, CPU nuclear 141 can judge that each program of separating is as the handling procedure that will download in a downloading process from a handling procedure corresponding to a process.In addition, when a plurality of handling procedures corresponding to a plurality of processes had the size of data that can comprise in the 142b of the handling procedure memory block of internal RAM 142, CPU nuclear 141 can be judged the handling procedure that will download corresponding to a plurality of handling procedures conducts of a plurality of processes in a downloading process.

When having determined the handling procedure that will download in described judgement, the CPU of high-speed CPU 131 nuclear 141 is to low speed CPU 132 output download requests, request download handler (being used to rewrite the request of handling procedure) (step S112).

The low speed CPU 132 that has received this download request carries out processing, downloads and the described corresponding handling procedures of high-speed CPU 131 requests (transmitting the process of handling procedure).That is, received in the handling procedure of low speed CPU 132 from be stored in external ROM 133 of download request and optionally read the high-speed CPU 131 processing of request programs that to download.In case low speed CPU 132 has read handling procedure, it with download handler in high-speed CPU 131.

When the request of low speed CPU 132 beginning handling procedures was downloaded, the handling procedure that high-speed CPU 131 will transmit (download) stored among the handling procedure memory block 142b of internal RAM 142 (step S113).At this moment, wipe data (executed handling procedure) among the handling procedure memory block 142b that is stored in internal RAM 142.That is, in step S113, rewrite the handling procedure among the handling procedure memory block 142b that is stored in internal RAM 142.

When entire process program that low speed CPU 132 downloads is stored among the handling procedure memory block 142b of internal RAM 142, i.e. (step S114 when finishing from low speed CPU 132 download handler, "Yes"), notice (step S115) is finished in the CPU of high-speed CPU 131 nuclear 141 download from download to low speed CPU132 output expression that finish.

In addition, the same with top step S107 when finishing the download of handling procedure, the handling procedure (step 107) that the CPU nuclear 141 of high-speed CPU 131 is carried out among the handling procedure memory block 142b that is stored in internal RAM 142.In the case, the CPU of high-speed CPU 131 nuclear 141 is carried out the handling procedure that is stored among the 142b of handling procedure memory block also with reference to the Processing Structure that obtains in pre-service.For instance, when the detection of enforcement character line was handled as second processing, described handler reference was stored in result (information of expression character zone) the detection character line of the character zone detection processing of conduct first processing among the 142d of Processing Structure memory block.

In addition, identical with top step S108, result's (result) that the CPU of high-speed CPU 131 nuclear 141 is stored in execution the handling procedure among the handling procedure memory block 142b of internal RAM 142 stores among the result memory block 142d of internal RAM 142 (step S108).

When use was loaded in finishing dealing with that handling procedure among the handling procedure memory block 142b of internal RAM 142 implements, the CPU nuclear 141 of high-speed CPU 131 judged whether to finish the processing (processing that all handling procedures will be carried out) (step S109) of whole series.When above-mentioned judgement is the processing of whole series (step S109 when having finished, "Yes"), the CPU of high-speed CPU 131 nuclear 141 is to the information of control assembly 112 outputs to the distribution of the result among the result memory block 142d that is stored in internal RAM 142 identifying information (information of identification mail).

In addition, if being whole series of processes, above-mentioned judgement do not finish, promptly, if above-mentioned judgement is to have the handling procedure (step 109 that will carry out subsequently, "No"), the CPU of high-speed CPU 131 nuclear 141 returns step S111, and the processing of implementation step S111 to S115 and S107 to S108 once more.In the case, the handling procedure that high-speed CPU 131 rewrites among the handling procedure memory block 142b that is stored in internal RAM 142 is next handling procedure, and implements to handle according to next handling procedure.

In classification of mail equipment 100, from external memory storage, will determine that the classification destination of classification destinations is determined to handle and going in the internal RAM in the high-speed CPU according to each handling procedure unit load of carrying out as high-speed CPU 131 corresponding to a plurality of handling procedures of various processing.This just can improve the processing speed in the definite processing in whole classification destination.As a result, can also in classification of mail equipment 100, realize paper process more efficiently.
