After the second signal sent by the processor No. L to the processor 10 is processed, the connection 40 is again transmitted through the navigation control unit 20 and the register 7 is connected. The processing is performed with the same number of pages as the number of pages stored in the buffer 7: the second page is stored in the temporary storage 70. For example, the first M + 1 w and the inner valley are stored in the scratchpad output page to the (M+1) MN page starting from the first page, and then the last crawl and ^^, the same content is stored in the temporary The ^7Qt>_H phase signal is sent to the page turning control unit 20 and automatically enters the sleep mode. [0013] When reading using the e-reader 100 described above, the processor is accommodated from the Keilong 50 towel_to the material_towel, the miscellaneous material = the page turning control unit 2, and then self-connected to the sleep mode to save power = when receiving When the external (four) signal is sent, (4) the control list (10) will turn the page on behalf of the money and display the page content on the display screen. It can be seen that the processor 10 is in the intermittent sleep mode and does not need to be in the working state. When the air conditioner 1 is in the sleep mode, 099141382, the form number plane 1 is 7 1 / the total page 201222324, and the small page turning control unit 2 is replaced; the machine is 〇 receiving and executing the page turning generated by the input unit 60 Instructions to save power. [0018] [0018] [0018] [0018] printing - and referring to FIG. 1 and FIG. 2, t, FIG. 2 is a flow chart of the steps of the pain control method of the electronic reader of the present invention, wherein the steps are Step 209 is performed by the processing benefit, and step 211 is performed by the page turning control unit. The step of the power saving control method includes the following steps: Step S201: Display the selected page content on the display screen. Step S2G3 prompts the user to set a range of reading pages. Specifically, the pop-up dialog box prompts the user to set the threshold value and the end value, such as N and Μ, which are self-sewn. In other embodiments, the reading page range (4) may also be pre-set by the system. The step S2G5' judges whether the user has finished setting the reading page range, and if not, returns to step S2G3, and if so, enters the step lake. In step S207, the page content of the set page range is stored in the temporary register. In the initial stage, the processor 1G stores the contents of the first page from the scratchpad. When the processing (4) is awakened from the sleep mode, the processing H1G will be from the next page of the last page stored in the temporary storage (4), and the page number of the last page stored in the temporary lion is the same. The contents of the number of pages are stored in the memory. For example, the content of the M+1th to the (M+1)+ (M°, W (ie, the MN page starting from the M+1th page) is stored in the temporary storage and automatically transmitted in step S209'. The first signal is sent to the page turning control unit 2 to enter the sleep mode. 099141382 Form No. A0101 Page 8 / Total 16 Pages 0992071992-0 [0019] 201222324 [0020] Step S211, after the page turning control unit 20 receives the first signal, [0021] Referring to FIG. 3, step S211 specifically includes: [0022] Step S2110, receiving a page turning instruction and displaying the page content after the page turning on the display screen 40. wherein the page turning instruction is input The unit 60 is generated according to the touch operation of the user.
