ろいろな情報をそこに一度に表示することができない。[Prior Art] As the name suggests, a handheld terminal is something that is held in the hand. Therefore, there is a limit to the size of the display screen, and it is not possible to display a variety of information at once, unlike a so-called display device of a personal computer.
このため電池電圧が低下したことを使用者に報知するに

できる。Therefore, it is necessary to take some measures to notify the user that the battery voltage has decreased. Jitsukaisho 60-57839
In the device disclosed in the above publication, the user is notified of a drop in battery voltage by blinking the display content on one display section. In this way, the screen display based on the program being executed at the time is used as is, so that the minimum necessary processing can be performed using that display before the battery is completely discharged.
［発明が解決しようとする課題］
しかし乍ら、現在手持型電子計算機端末に使用されてい

である。視認性の点ではプラズマによるものの方が好ま
しいが、駆動に要する電圧が高いため、この種装置には
使用されていない。[Problems to be Solved by the Invention] However, most of the display devices currently used in hand-held computer terminals are based on liquid crystals, and their visibility is poor. Although it is preferable to use plasma in terms of visibility, it is not used in this type of device because the voltage required for driving is high.
このように視認性の良くない液晶表示装置に於て表示を
一時的に消滅させるだけの上記方式は視認性が今−歩不
足しており、電池切れの警告として使用者へ与える印象
がいささか不足している。The above-mentioned method, which only temporarily erases the display on liquid crystal display devices with poor visibility, lacks visibility and leaves a somewhat insufficient impression on the user as a warning that the battery is running low. are doing.
［課題を解決するための手段］
そこで本発明では、電池電圧低下を検知する検知手段と
、該手段の出力信号に応動し、そのとき実行されている
プログラムによる画面を所定間隔で反転表示させる制御
手段を用い上記課題の解決を図る。[Means for Solving the Problems] Accordingly, the present invention includes a detection means for detecting a battery voltage drop, and a control that responds to an output signal of the means and displays a screen in reverse video at predetermined intervals according to a program being executed at the time. We will try to solve the above problems by using means.
［作 用］
即ち上記制御手段により、実行中のプログラムに関する
情報が途切れなく表示されながら画面が反転表示され、
これにより使用者は電池電圧低下を明確に認識でき、し
かもその時実行している入力作業等を中断されることも
ない。[Function] That is, the control means causes the screen to be displayed in reverse video while continuously displaying information regarding the program being executed;
This allows the user to clearly recognize the drop in battery voltage, and also does not interrupt the input work, etc. that is being performed at the time.

A liquid crystal display device I (LCD) 7 displays information supplied from the same <CPtJ2. Reference numeral 8 reads a barcode attached to a product (not shown) using a barcode reader. 9 emits an input confirmation sound with a buzzer. Reference numeral 10 denotes an input/output port for exchanging information with a host computer (not shown).

せる。The CPU 2 is executing a certain program stored in the ROM 3 or RAM 4, for example, a product ordering program, and the LCD 7 displays an application 1 as shown in FIG.
Assume that the main screen is displayed. At this time, when the voltage monitoring circuit 11 detects a drop in the terminal voltage of the main battery 12 and supplies an interrupt signal to the CPU 2, the CPU 2 responds to this and enters an interrupt processing routine, and the screen of the LCD 7 is displayed as shown in FIG. is displayed in reverse video for 1 second, and then returned to the original screen 13. If the terminal voltage continues to drop, the CP
U2 displays the inverted screen 14 on the LCD 7 for one second each time.
