The financial storer of storage financial information is installed on financial storer substrate 10.Finance storer is flash memory or OTP-ROM etc.Memory print is installed on EJ storer substrate 11 to EJ (electronics day-to-day account) storer of the printing information on receipt.Finance storer substrate 10 and EJ storer substrate 11 are covered by the epoxy resin of black.At printer, control on substrate 12 the printer control CPU18 for each mechanism of printer main body 2 is controlled is installed.
CPU21 for financial control as financial control portion is installed on financial control substrate 13, as the flash memory 22 of the 1st storage part, distort and confirm with CPU23, flash memory 24 as the 2nd storage part, RTC (real-time clock) 25, as the MCU (memory control unit) 26 of rewriting control part, as standby one-shot battery 27 and the reset IC28 of power supply as distorting the program of confirming control part.
Financial control is carried out financial control etc. with CPU21, and this financial control is for carrying out to writing of the financial information of financial storer and writing to the printing information of EJ storer.In flash memory 22, store financial control and with CPU21, carry out the financial control program of financial control.Financial control is the financial control program based on being stored in flash memory 22 with CPU21, carry out to the financial information of financial storer write and to writing of the printing information of EJ storer etc.In addition, the flash memory 22 of the manner is serial flash.
Program is distorted and is confirmed to distort and to confirm to control with CPU23, and this is distorted and confirms to control situation about not being tampered for confirming to be stored in the financial control program of flash memory 22.In flash memory 24, have program stored therein distort confirm with CPU23 distort confirm to control distort confirmation control program.Program is distorted and is confirmed based on being stored in, in flash memory 24, to distort confirmation control program with CPU23, when starting printer 1, is relatively stored in financial control program in flash memory 22 and financial control program substantially.In addition, if the content of two control programs is inconsistent, program is distorted and is confirmed with CPU23, printer 1 to be stopped, if the content of two control programs is consistent, program is distorted and confirmed to make printer 1 become the state that can work with CPU23.In addition, the flash memory 24 of the manner is paralleling flash memory.In addition,, in the manner, the data of the several bytes that started by the data from being stored in the start address of flash memory 24 form vector table portion.
RTC25 possesses storage and distorts by described later that testing agency's (omit diagram) is detected carries out the generation date of tampering and the function of time to financial storer.RTC25 for example exports the wavy digital signal of rectangle.If after printer 1 finishes and the use that completes its manufacturing process and printer 1 started, distort testing agency and detect the tampering to financial storer, the level of the output signal of RTC25 changes.For example, if distort testing agency, detect the tampering to financial storer, the level of the output signal of RTC25 is switched to high level or is switched to low level from high level from low level.
MCU26 rewrites control, this rewriting control for rewrite be stored in flash memory 24 distort confirmation control program.This MCU26 possesses and has stored for rewriting the flash memory of the rewrite control program of controlling.By describing in the back the rewriting that MCU26 carries out in detail, control.
One-shot battery 27 is connecting the required various electronic units of supply standby power such as SRAM (static random access memory).These electronic units are connected with one-shot battery 27 via resistance 29 (with reference to Fig. 4).The following function of resistance 29 performance, that is: prevent from causing these electronic units impaired because of the dash current from one-shot battery 27.
In addition, on one-shot battery 27, via switch 30, flash memory 24, MCU26 and reset IC28 have been connected.Flash memory 24, MCU26 and reset are directly connected to one-shot battery 27 via switch 30 with IC28.That is, flash memory 24, MCU26 and reset with IC28 not via producing the electronic units such as resistance of pressure drop but be directly connected to (with reference to Fig. 4) on one-shot battery 27.Switch 30 is conventionally in cutting off flash memory 24, MCU26 and resetting by the open mode being connected between IC28 and one-shot battery 27.In addition, if detect the situation of financial storer being carried out to tampering by the testing agency of distorting illustrating below, switch 30 becomes closure state, connect flash memory 24, MCU26 and reset with IC28 and one-shot battery 27, and from one-shot battery 27 to flash memory 24, MCU26 and reset supply with electric power with IC28.
In addition, fiscal module 3, except above-mentioned structure, also possesses testing agency's of distorting (omitting diagram), for detection of financial storer being carried out to the situation of tampering.This is distorted testing agency and for example detects the situation that unloads fiscal module 3 and unload coating member 16 from housing 15 from printer main body 2.In addition, this is distorted testing agency and unloads fiscal module 3 and framework 14, utilize drilling machine etc. to open the situation in hole such as detecting from printer main body 2.; distorting testing agency unloads fiscal module 3 and from housing 15, unloads the situation of coating member 16 by detecting from printer main body 2; or by detecting from printer main body 2, unload fiscal module 3 and framework 14, utilize drilling machine etc. to open the situation in hole, thereby detect, financial storer is carried out to tampering.
The rewriting that MCU carries out is controlled
Fig. 5 is the process flow diagram of the example controlled of the rewriting carried out of MCU26.In fiscal module 3, if distort testing agency, detect financial storer is carried out to tampering (step S1), Closing Switch 30, from one-shot battery 27 to flash memory 24, MCU26 and reset and supply with electric power (step S2) with IC28.So, from resetting, by the reset signal of IC28 output, be input to MCU26 (step S3).
Then, MCU26 reads the state of the interrupt output of RTC25.That is, MCU26 confirms whether the level of the output signal of RTC25 variation (step S4) has occurred.In the situation (be the situation of "Yes" in step S4) that has occurred to change at the level of the output signal of RTC25, MCU26 rewrites to be stored according to rewrite control program and distorting confirmation control program (step S5) in flash memory 24.In the manner, in step S5, MCU26 writes for deleting and distorts the fixed data of confirming control program to flash memory 24.In addition,, in step S5, MCU26 rewrites and distorts confirmation control program from the start address of flash memory 24.
In addition, in step S5, MCU26 sends the data of 4 bytes to flash memory 24 in the mode of byte access, and according to the regulation order accordingly of the specification with flash memory 24, rewrites to be stored in and distorts confirmation control program in flash memory 24.For example, in step S5, first MCU26 is to address bus setting " AAAh ", to data bus setting " AAh ".Then, MCU26 is to address bus setting " 555h ", to data bus setting " 55h ".Then, MCU26 is to address bus setting " AAAh ", to data bus setting " A0h ".Then, MCU26 is to address bus setting " 000h ", to data bus setting " 00h ".Then, MCU26 triggers WE (allowing to write) terminal.When WE terminal is triggered, data writing in flash memory 24 " 00h ".That is,, when WE terminal is triggered, in flash memory 24, write 0 data.
In step S5, if rewrite, be stored in and distort confirmation control program in flash memory 24, the rewriting that MCU26 carries out is controlled and is finished.In addition, in the situation (being the situation of "No" in step S4) not changing at the level of the output signal of RTC25, do not rewrite to be stored in and distort confirmation control program in flash memory 24, but finish the rewriting that MCU26 carries out, control.
The main effect of present embodiment
As described above, in the manner, if distort testing agency, detect the level that financial storer is carried out to the output signal of tampering and RTC25 variation has occurred, MCU26 rewrites to be stored in and distorts confirmation control program in flash memory 24.That is, in the manner, in the situation that be accompanied by the tampering of financial storer likely to be caused reading wrongly distort, confirm control program, MCU26 rewrites and distorts confirmation control program, so that cannot read, distorts confirmation control program.Thereby, in the manner, can prevent from distorting confirmation control program and be read by improper.
In addition, the required time of rewriting of distorting the total data of confirming control program of the manner is about 12 seconds.On the other hand, until unload fiscal module 3 and unload coating member 16 or utilize the perforates such as drilling machine that flash memory 24 is exposed from housing 15 from printer main body 2, need 1 minute above time framework 14.Thereby in the manner, in the situation that carried out distorting the rewriting of confirming control program, the total data of conventionally distorting confirmation control program is rewritten (that is, distort and confirm that the total data of control program is deleted).
In the manner, MCU26 writes for deleting and distorts the fixed data of confirming control program to flash memory 24.That is, in the manner, MCU26 distorts confirmation control program in order to rewrite, as long as fixed data is write to flash memory 24.Therefore,, in the manner, it is easy that the control of MCU26 becomes.
In the manner, if the level of the output signal of RTC25 changes, MCU26 rewrites to be stored in and distorts confirmation control program in flash memory 24.That is, in the manner, even if distort testing agency, detect and carried out tampering, if the level of the output signal of RTC25 does not change, MCU26 just can not rewrite to be stored in and distort confirmation control program in flash memory 24.Thereby, in the manner, for example, in the manufacturing process of printer 1, can prevent from distorting and confirm that control program is rewritten mistakenly.
In the manner, MCU26 rewrites and distorts confirmation control program from the start address of flash memory 24.Thereby, even if the residual capacity of the one-shot battery 27 when for example MCU26 rewrites control is few, cause from one-shot battery 27 to MCU26 and the electric power of flash memory 24 supply interruption at short notice, the vector table portion that also can rewrite flash memory 24.Therefore,, in the manner, even if the residual capacity of the one-shot battery 27 when MCU26 rewrites control is few, also can prevent from deliberately and wrongly reading the situation of confirming control program of distorting.In addition, even if for example the capacity of one-shot battery 27 is little and cause rewriting while controlling from one-shot battery 27 to MCU26 and the electric power of flash memory 24 is supplied with and interrupted at short notice, the vector table portion that also can rewrite flash memory 24 at MCU26.Therefore,, in the manner, even if reduce the capacity of one-shot battery 27, also can prevent from deliberately and wrongly reading the situation of confirming control program of distorting.
In the manner, flash memory 24, MCU26 and reset with IC28 not via producing the electronic units such as resistance of pressure drop but be connected directly on one-shot battery 27.Thereby, in the manner, to flash memory 24, MCU26 and reset while applying the voltage from one-shot battery 27 with IC28, the useless pressure drop that can not have a resistance etc. and to cause.Therefore, in the manner, even if the residual capacity of the one-shot battery 27 when for example MCU26 rewrites control is few, also can make IC28 work for flash memory 24, MCU26 and reset, to carry out the rewriting of MCU26, control.In addition,, in the manner, the useless pressure drop causing owing to can not having a resistance etc., therefore, even if for example the capacity of one-shot battery 27 is little, also can carries out the rewriting of MCU26 and control.That is, in the manner, even if reduce the capacity of one-shot battery 27, also can make flash memory 24, MCU26 and reset with IC28 work, to carry out the rewriting of MCU26, controlling.
