If the above-mentioned one-way juice dispenser 1 0 1 returns to step S 1 04. If the above-mentioned y rate information is the same, the controller m updates the non-volatile memory 1 〇 4 using the sheep eagle /=, then s 1 〇 8). The controller 101 will calculate the upper squad (step unit 103 (step S116). Because of this, whenever the non-pinch 7 is displayed on the display internal data, the display unit 103 is "dry" = body 1 〇4 is replaced by the controller 2 0 2) automatically calculate the above non-volatile cutting tool (control, and will calculate the above utilization rate 4: the utilization rate of the body L04 can be compared without the previous use of the display In the display unit 103. The information is directly used by the display unit to "utilize the information. g is different from the utilization rate.

1262502 i, invention description (fantasy " ' """ ---- For example, when the above external storage device has a power supply, the non-volatile memory 104 corresponds to the latest update The utilization unit is in a first state to display the most recently updated utilization information. When the display unit 丨〇3 is in the absence of power supply (for example, the external storage device 1 1 〇 电脑 电脑 电脑 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( A bistab 1 e display, such as an e_paper, an electronic ink (e-丨nk) technology display, or other organic bistable light-emitting diodes (abbreviated as 〇BLED). Whenever the non-volatile memory 丨〇4 is changed by internal data, the bistable display automatically switches to a display state to reflect the utilization information of the non-volatile memory 1 。4. The display is still in the above display state without power supply. The display state of the above bistable display can be observed to know the utilization information of the non-volatile memory 丨〇 4. For example, the above display unit 1 〇 3 For the ratchet (ra ΐ ch ).
