  Next, the relationship between the screen displayed on the display unit 2 and the operation buttons will be described.

  In the reproducing apparatus 1, when the power switch 4b is turned on, the latest end state is reproduced based on the data stored in the sub CPU 16 (resume function).

  Assume that the title list screen of “Video” is displayed as shown in FIG. When the button 3b is pressed (touched) in this state, the “Music” title list screen shown in FIG. 10 is displayed, and when the button → 3b is further pressed, the “Photo” title list screen shown in FIG. 11 is displayed. When the → button 3b is further pressed, a title list screen of “Setup” shown in FIG. 12 is displayed. When the ← button 3a is pressed, the title list screen is switched on the contrary. That is, by pressing the → button 3b, the title list screen is switched in the order of “Video”, “Music”, “Photo”, “Setup”, and by pressing the ← button 3a, the title list screen is “Setup”, It is switched in the order of “Photo”, “Music”, and “Video”.

  Then, a cursor in the screen is moved from these title lists with the up / down buttons 3e to select a predetermined file, for example, a video file, and the file selected with the ENTER button 3c is executed. For example, the video of the selected video file is displayed from the display unit 2.

Next, the operation of the ↑ / ↓ button 3e will be described with reference to the flowcharts shown in FIGS.
(1) While resetting the current time Tc = 0, it is checked whether any of the touch sensors of the ↑ / ↓ buttons 3e has a key touch (S1, S2).

When it is detected that a key touch is made in S2, the touched key is set to K_start, T_start = Tc (S3), and time measurement of Tc is started (S4), and the finger is released within a predetermined time. Whether the touched sensor has been slid (S6) and whether the touched time is within a predetermined time (S7).
(2) If it is determined in S5 that the finger has been released within the predetermined time, the mode shifts to the short press key mode and a short press code is issued (S8).

When K_start is “1” or “2” in FIG. 2, a code for raising the cursor is issued. When K_start is “4” or “5” in FIG. 2, a code for lowering the cursor is issued. When K_start is “3” in FIG. 2, a code for moving the cursor is not issued.
(3) When the touched sensor is not slid (S6) and the touched time exceeds a predetermined time (S7), the mode shifts to the long press key mode and a long press code is issued. (S9). T_long = Tc.

  Here, when K_start is “1” or “2” in FIG. 2, a code for raising the cursor is issued. When K_start is “4” or “5” in FIG. 2, a code for lowering the cursor is issued. When K_start is “3” in FIG. 2, a code for moving the cursor is not issued.

  Measurement of the time Tc is started (S10), whether the finger is removed within a predetermined time (S11), whether the touched sensor is slid (S12), whether the touched time is within the predetermined time Watching (S13).

When the finger is removed within a predetermined time, the process is terminated. When the touched sensor does not slide and the touched time exceeds the predetermined time, the mode again shifts to the long press key mode and a long press code is issued (S9).
(4) In S6 and S12, when it is detected that the touched sensor has been slid, the mode shifts to the slide mode.

  Here, T_slide = Tc (S14), Tc time measurement is started (S15), whether the finger is released (S16), and two or more touch sensors separated from the K_start touch sensor are slid. It is checked whether it is touched (S17).

  When the touch sensor is slid from the touch sensor of K_start to two or more touch sensors and is not touched, that is, when the slide is one touch sensor, the following key code is issued (S18).

If the slide is up, issue a code to raise the cursor. If the slide is down, issue a code to move the cursor down. When not sliding, the key code is issued as follows. When K_start is “1” or “2” in FIG. 2, a code for raising the cursor is issued. When K_start is “4” or “5” in FIG. 2, a code for lowering the cursor is issued. When K_start is “3” in FIG. 2, a code for moving the cursor is not issued.
(5) When the touch sensor is slid to and touched two or more touch sensors from the K_start touch sensor, the moving speed of the cursor is set according to the slide speed (S19), and a key code is issued (S20).

  When 0 <t1 <t2, when Tc-T_slide <t1, the slide speed is high, when t1 <or = Tc-T_slide <t2, the slide speed is medium, and when t2 <or = Tc-T_slide The slide speed is low. By setting tn appropriately, finer speed setting is possible.

When the slide is upward, a code for raising the cursor at the speed set in this way is issued. If the slide is down, a code is issued to move the cursor down at the speed set in this way.
(6) After issuing the key code in S20, the key code is biased. That is, after that, it is detected whether the key code is up or down (S21). When the key code is up, Key_bias = UP (S22), and when the key code is down, Key_bias = DOWN (S23).

Here, all the measurement times are reset to the current time (S24), the measurement of the time of Tc is started (S25), whether or not the finger is released (S26), two or more touch sensors separated from the K_start touch sensor Is slid and touched (S27), the time interval T_cycle for issuing the key code set in S19 is observed. (S28)
(7) When it is detected in S26 that the finger has been released, the process is terminated. When two or more touch sensors separated from the touch sensor of K_start are slid and touched, the process returns to S19 and a key code is issued again (S27).

  If two or more touch sensors are not slid and touched, and more than T_cycle set in S24 to S19 has elapsed (S28), it corresponds to Key_bias set in S22 and S23. A direction key code is issued (S29).

  As described above, in this embodiment, when the touch sensor is slid to two or more touch sensors away from the touch sensor and is not touched, that is, when the slide is one touch sensor, it is regarded as not a slide with respect to the touch sensor. Even if the user does not intend to slide, but simply intends to touch and the finger moves a little, there will be no erroneous operation.

Next, an operation of skipping, for example, a CM using the ↑ / ↓ button 3e during video reproduction will be described with reference to the flowcharts shown in FIGS.
(1) While resetting the current time Tc = 0, it is checked whether any of the touch sensors of the ↑ / ↓ buttons 3e has a key touch (S1, S2).

When it is detected that a key touch is made in S2, the touched key is set to K_start, T_start = Tc (S3), and time measurement of Tc is started (S4), and the finger is released within a predetermined time. Whether the touched sensor has been slid (S6) and whether the touched time is within a predetermined time (S7).
(2) If it is determined in S5 that the finger has been released within the predetermined time, the mode shifts to the short press key mode and a skip key code is issued (S8). As a result, the video is skipped for a predetermined time, for example, about 15 seconds.
(3) When the touched sensor is not slid (S6) and the touched time exceeds a predetermined time (S7), the mode shifts to the long press key mode and the long press skip key code. A code for issuing is issued (S9). Thereby, the video is skipped for a predetermined time, for example, 30 seconds, 45 seconds, etc., according to the long press time.

  Measurement of the time Tc is started (S10), whether the finger is removed within a predetermined time (S11), whether the touched sensor is slid (S12), whether the touched time is within the predetermined time Watching (S13).

When the finger is removed within a predetermined time, the process is terminated. When the touched sensor does not slide and the touched time exceeds the predetermined time, the mode again shifts to the long press key mode, and a long press skip key code is issued (S9).
(4) In S6 and S12, when it is detected that the touched sensor has been slid, the mode shifts to the slide mode.

  Here, T_slide = Tc (S14), Tc time measurement is started (S15), whether the finger is released (S16), and two or more touch sensors separated from the K_start touch sensor are slid. It is checked whether it is touched (S17).

When the touch sensor is not touched by being touched by two or more touch sensors away from the K_start touch sensor, that is, when the slide is one touch sensor, a skip key code is issued (S18).
(5) When the touch sensor is slid from the touch sensor K_start to two or more touch sensors, the moving speed of the cursor is set according to the slide speed (S19), and a skip key code is issued (S20). .

  When 0 <t1 <t2, when Tc-T_slide <t1, the slide speed is high, when t1 <or = Tc-T_slide <t2, the slide speed is medium, and when t2 <or = Tc-T_slide Judge the slide speed as low.

Then, a skip key code corresponding to the speed is issued.
(6) After issuing the key code in S20, the key code is biased. That is, after that, it is detected whether the key code is up or down (S21). When the key code is up, Key_bias = UP (S22), and when the key code is down, Key_bias = DOWN (S23).

  Here, all the measurement times are reset to the current time (S24), the measurement of the time of Tc is started (S25), whether or not the finger is released (S26), two or more touch sensors separated from the K_start touch sensor Whether or not is touched by sliding (S27), the time interval T_cycle for issuing the key code set in S19 is observed (S28).

  If it is detected in S26 that the finger has been released, the process is terminated. When two or more touch sensors separated from the touch sensor of K_start are slid and are touched, the process returns to S19 and a skip key code is issued again (S27).

  When two or more touch sensors that are separated from each other are not slid and touched, and more than T_cycle set in S24 to S19 has elapsed (S28), a skip key code is issued (S29).

  As a result, the user can skip CM and the like with a simple operation.

  In addition, this invention is not limited to said embodiment.
