Abstract

A recording and/or reproducing apparatus includes a microphone, a semiconductor memory, an operating section and a controller. An output signal from the microphone is written in the semiconductor memory and the written signals are read out from the semiconductor memory. The operating section performs input processing for writing a digital signal outputted by an analog/digital converter, reading out the digital signal stored in the semiconductor memory and for erasing the digital signal stored in the semiconductor memory. The control section controls the writing of the microphone output signal in the semiconductor memory based on an input from the operating section and the readout of the digital signal stored in the semiconductor memory. The control section operates so that, if, when the signals written in the storage section is read out from it, an input for erasure is entered by the operating section, the signal being read out from the storage section is erased when, after reading out the signal from the storage section for a pre-set period, an input for erasure is again entered from the operating section.

Especially By pressing the display button 61h, the recording date, recording time and remaining recordable time will be sequentially displayed on the liquid crystal display panel 41. If the user operates the 1C recorder 1 in a dark environment, the backlight 42 may be illuminated in the display unit 40. Referring to FIG. 9, if the light button 61g is pressed, the CPU 32 of the 1C recorder 1 proceeds to step ST51 to check whether the backlight button 61g is pressed. If the back button 61g is pressed, the process will be transferred to step ST52, and if not, the process will be transferred to step ST56. At step ST52 ', the CPU 32 resets the timer 33 to start time counting. If the timer 33 is reset, the process proceeds to step ST53 to determine whether the backlight 42 has been lit for more than 10 seconds. If it is within 10 seconds, then the backlight will be continuously lit, or if it has exceeded -20- (Xu first read the precautions before filling in this page) This paper size applies the Chinese National Standard (CNS) A4C grid (210X297) 4 52 8 C-) _____ 1Γ 5. Description of the invention 彳 8) If the time is 10 seconds, the backlight 42 will be turned off in step ST55. If the backlight 42 is continuously lit in step S, the CPU 3 2 returns to step ST51 to determine whether the backlight button 61g has been pressed. If the CPU 32 finds that the backlight button 6U has not been pressed, the process proceeds to step ST56. In step ST56, the CPU 32 determines whether any of the buttons 61 of the timer 33 has been pressed while the backlight 42 is lit. If in step ST57 the CPU 32 finds that any of the buttons 61 of the timer 33 is pressed while the backlight 42 is lit, the CPU 32 resets the timer 33 again to start Time count. If no buttons have been pressed, the process returns to step ST53 again. In step ST53, it is determined whether the backlight 42 has been turned on for more than 10 seconds. The lighting state is maintained for 10 seconds from the start of lighting, and if it has exceeded 10 seconds, the backlight 42 is turned off in step ST5.
