The recording progress status is displayed differently when the number of music files to be recorded is plural and when the number of music files to be recorded is one.

  When the number of music files to be recorded is plural, the ratio of the number of recorded music files to the total number of music files to be recorded is displayed on the liquid crystal display 51 as the recording progress status. For example, in the indicator 51a (recording progress display means) 51a provided with five lighting areas of a predetermined size adjacent to each other as shown in FIG. 2A, the number of lighting areas to be lit is increased. Thus, it is conceivable to display the recording progress status in five stages. That is, when there are 10 music files to be recorded, if the position of the lighting area to be lit is increased sequentially from one end to the other end, FIG. As shown in i) to (vi), all the lighting areas are turned off in the initial state, and when two music files are recorded, one lighting area is turned on and 20% of music files have been recorded. Is displayed, and when the music files for 4 songs are recorded, the lighting area to be turned on is increased by one, and it is displayed that 40% music files have been recorded as two, and 6 songs are recorded. When the music file is recorded, the lighting area to be further lit is increased by one to indicate that 60% of the music files have been recorded, and when eight music files are recorded. Further lighting The area is incremented by 1 to indicate that 80% of the music files have been recorded, and when all 10 music files have been recorded, all the lighting areas are turned on, and the recording is completed. By displaying this, it is possible to display the recording progress of the music file.

  On the other hand, when the number of music files to be recorded is one, the indicator 51a is used to display a display indicating that the music file is being recorded as the recording progress status while being updated every predetermined unit time. . Here, the display indicating that the music file is recorded may be any display. For example, as shown in FIG. 2B, the display is turned on every predetermined unit time (200 ms). As shown in (i) to (vi), the position of the lighting area to be moved moves in a certain direction, so that a display indicating the passage of time or a lighting area that is lit every predetermined unit time is displayed. A display in which the position changes randomly, a display in which other characters move, or any display can be performed.

  The key matrix 52 is formed in a sheet shape using a transparent material, and has a switch in which electrodes are arranged in a vertical and horizontal manner like a grid. When the user presses various operation buttons provided on the operation screen displayed on the liquid crystal display 51, an operation instruction corresponding to the pressed position is input to the control unit 60 via the display control / input detection unit 53. .

When the ratio of the number of music files reaches 60% (step S7: Y), the number of lighting areas to be lit is increased by one to display 60% recorded (step S8). When the ratio of the number reaches 80% (step S9: Y), the number of lighting areas to be lit is increased by one to display 80% recorded (step S10), and all the recording target music files are recorded. When the recording is completed (step S11: Y), all turns on the lighting area of the five in the 100% recorded display (step S12).

  On the other hand, when the number of music files to be recorded is one (step S1: N), the control unit 60 turns off all five lighting areas of the indicator 51a in cooperation with the main microcomputer 61 and the sub-microcomputer 62 ( Step S21). Then, a reset signal is input to the counter 80, and the count number of the counter 80 is set to C = 0 (step S22). And it waits until 200 ms is time-measured by the time measuring part.

  Next, when 200 ms is measured by the time measuring unit (step S23: Y), the control unit 60 sends a count signal to the counter 80, sets the count number of the counter 80 to C = C + 1 (step S24), and sets the indicator 51a. Display according to the number of counts (step S25). Specifically, when the count number is C = 0, the display shown in FIG. 2 (b) (i) is counted. When the count number is C = 1, the display shown in FIG. 2 (b) (ii) is counted. When the number is C = 2, the display shown in FIG. 2 (b) (iii) is displayed. When the count number is C = 3, the display shown in FIG. 2 (b) (iv) is displayed, and the count number is C = 4. In this case, the display shown in FIGS. 2B and 2V is performed. When the count number is C = 5, the display shown in FIGS. When the count number is C = 6, the display returns to the display shown in FIGS.

  When the counter number of the counter 80 becomes C = 6 (step S26: Y), the control unit 60 sends a reset signal to the counter 80, and resets the count number of the counter 80 to C = 0 (step S27). ). The above process is repeated until the recording of the music file is completed (step S28: Y).

  According to the embodiment described above, when the number of music files to be recorded is plural, as shown in FIG. 2A, the number of recorded music files with respect to the number of music files to be recorded Since the ratio is displayed on the liquid crystal display 51 as the recording progress, the user can easily grasp the recording progress of the music file.

  If the number of music files to be recorded is one, the display shown in FIG. 2B is performed instead of the recording progress status, so that a meaningful display can be performed. In the above embodiment, the lighting region to be turned on is switched every time 200 ms is counted, so that the user can visually determine the passage of time.

  In addition, as shown in FIG. 2, it is possible to easily grasp whether a plurality of recording target files are currently recorded or one recording target file is recorded by observing the lighting state of the lighting area in the indicator 51a. be able to.
