Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention has at least a first constant speed running mode and a second constant speed running mode. The present invention relates to a running display device such as a tape recorder.

0002

[Conventional technology]

Conventional tape recorders that record and play back audio, etc., can record, for example, the content of a meeting. In order to listen to the recorded content and create minutes, etc., In addition to the line mode, there is a constant speed mode that is slightly slower than this mode, and there is also a constant speed mode that is slightly slower than this mode. For use in practice, etc., you can select a constant speed driving mode depending on your level of proficiency. In addition to the normal constant speed driving mode, there is also a slightly slower or slightly faster speed mode. Tape recorders that have a constant speed running mode and multiple constant speed running modes are known. ing.

0003 In addition, the tape recorder has multiple Equipped with a display device consisting of segments or multiple dots. There is. FIG. 4 shows an example of the travel indicator 1, and in this example, each of the four sides is A total of 12 segments are arranged, 3 segments each.

0004 Then, these three segment groups 1a, 1b, 1c, and 1d on each side are blinked. The constant speed driving mode is displayed by controlling the controller.

[0005] That is, as shown in FIG. 5, each segment group 1a, 1b, 1c, 1d is The segments are displayed in a clockwise manner as a whole by controlling the blinking at a predetermined cycle when clicked. Indicates constant speed driving mode by flashing as if it is rotating in the opposite direction. can be done.

[0006]

[Problem that the idea aims to solve] By the way, in conventional tape recorders that have multiple constant speed running modes, this To display each of these multiple constant speed driving modes, display as shown in Fig. 4 and Fig. 5. In device 1, each segment group 1a, 1b, 1c, 1d flashes cyclically. The controlled period can simply be made slower or faster depending on the selected constant speed driving mode. You can check which driving mode is available among multiple constant speed driving modes by simply It was designed to make a judgment.

[0007] Therefore, even if the tape recorder has multiple constant speed running modes, The display on the driving display 1 that displays the mode is simply a distinction based on the length of the flashing cycle. , the display will be visually uniform, and you will not be able to see which driving mode you are using, etc. In some cases, it could not be easily determined without comparing the driving mode and flashing cycle.

[0008] Therefore, this idea takes into account these conventional problems, and is designed to solve multiple problems. The display shows which driving mode you are using among the constant speed driving modes. To provide a running display device such as a tape recorder that is easier to visually distinguish. It is.

[0011]

【Example】

Next, regarding one embodiment of the running display device such as a tape recorder according to this invention, This will be explained in detail with reference to FIG. 1 and subsequent figures.

0012 Figure 1 shows a display control system 1 in a running display device such as a tape recorder according to this invention. FIG. 2 is a block diagram showing an example of 0. In the same figure, 11 is the main microcomputer, 12 13 is a key input for inputting the operation mode to the tape recorder. 12 key operations, the input ports A1 and A2 of the main microcomputer 11 are A comparator 14 for outputting “H” level or “L” level respectively When the play operation is obtained, the switch operation is accepted and the play operation is in progress. This is a selector switch for selecting the constant speed driving mode.

[0013] Key input 12 is STOP (stop), PLAY (play), FF (fast forward). ), REW (rewind), and other operations to obtain various operating modes of the tape recorder. There is a corresponding signal. In the figure, STOP is a typical example. key 21, PLAY key 22, FF (fast forward) key 23, REW (volume) 24 shows key inputs associated with the return) key 24.

[0014] In response to the various key operations of these key inputs 12, the comparator 13 outputs the information shown in FIG. As shown in the figure, "H" level is applied to the input ports A1 and A2 of the main microcomputer 11. Or "L" level is output respectively, and the driving display is displayed via the main microcomputer 11. This is to control the device 1.

[0015] Additionally, there is a switch to select the constant speed driving mode during play. The switch 14 operates when the PLAY key 22 is operated at the key input 12, and the comparator 13 to the input port A1 of the main microcomputer 11. There is an "H" level input to port A2, and the play mode is activated by a known means (not shown). The switching operation is accepted and judged to be valid only when the code is obtained. It will be done.

[0016] The method for making this judgment will become clearer as described below, but the above It is assumed that the play mode is obtained as follows.

[0017] First, when the selector switch 14 is in the "N" position, as shown in FIG. The input port S1 of the main microcomputer 11 has "L" level and the input port S2 has an “L” level input, and is in normal constant speed driving mode (PLAY/NORMAL). ). In the case of a cassette tape recorder, it is 4.8 cm/sec.

[0018] Next, when the selector switch 14 is in the "H" position, the above-mentioned normal Compared to the constant speed driving mode, the high speed constant speed driving mode is approximately 25% faster ( PLAY/HIGH).

[0019] Furthermore, when the selector switch 14 is in the "L" position, the normal Compared to constant speed driving mode, there is a low speed constant speed driving mode where the speed is reduced by about 10% ( PLAY/LOW) Each of these constant speed running modes is controlled by a known method (not shown) via the main microcomputer 11. This is obtained by means of a canism drive means.

[0020] The display control system of the display device according to the present invention has the above configuration, and An example of the display in this mode is shown in FIG.

[0021] First, a1 in Fig. 3 shows the stop mode (STOP), in which all segments The light is off.

[0022] A2 to a4 in Fig. 3 are high-speed constant speed driving modes (PLAY/HIGH), respectively. , normal constant speed driving mode (PLAY/NORMAL) and low speed constant speed driving mode (PLAY/LOW).

[0023] In other words, in high-speed constant speed driving mode (PLAY/HIGH), each segment 3 of the groups sequentially Segment group 1a, 1b, 1c → 1b, 1c, 1d → 1c, 1d, 1a → 1d, 1a, 1b → 1a, 1b, 1c →... The blinking is controlled as follows (a2 in FIG. 3).

[0024] Next, in normal constant speed driving mode (PLAY/NORMAL), each segment Two of the two groups move clockwise in sequence. Segment group 1a, 1b→1b, 1c→1c, 1d→1d, 1a→ 1a, 1b →... Flashing is controlled as follows. (a3 in Figure 3) Furthermore, in low-speed constant speed driving mode (PLAY/LOW), each segment group One of them is clockwise in turn. Segment group 1a→1b→1c→1d→1a→... Flashing is controlled as follows. (a4 in Figure 3) In addition, in these constant speed driving modes, the segment groups are sequentially set for 400 msec. It is lit for a while.

[0025] A5 in Fig. 3 shows the fast forward mode (FF), in which two of each segment group clockwise in order Segment group 1a, 1b→1b, 1c→1c, 1d→1d, 1a→ 1a, 1b →... Flashing is controlled as follows.

[0026] A6 in FIG. 3 shows the rewind mode (REW), in which each segment group is the two in turn counterclockwise Segment group 1a, 1d→1d, 1c→1c, 1b→1b, 1a→ 1a, 1d →... Flashing is controlled as follows. In addition, rewind mode (REW) and fast forward mode ( FF), the blinking interval between segment groups is 200 msec in this example.

[0027] As described above, in each driving mode, the segment group moves clockwise or counterclockwise. The flashing is controlled as if it were rotating in the direction.

[0028] In particular, in the constant speed driving mode, it corresponds to each of multiple constant speed driving modes. Since the number of flashing segments is different, it is easy to see which mode is selected. Easily identified visually.

[0029] The above is a blinking control of the segment groups 1a, 1b, 1c, and 1d of three on each side. Although the case has been described above, the present invention is not limited to this embodiment.

[0030] Further, the present invention can also be applied to a travel display device or the like that is expressed using dots.

[0031] Furthermore, the blinking cycle is not limited to the above example, and can be fixed as in conventional devices. Even in fast driving mode, the flashing cycle may be changed depending on each mode. stomach.

[0032]

[Effect of the idea]

As explained above, according to the present invention, each of multiple constant speed driving modes is supported. and the number of blinking segments or dots on the display device is varied. Therefore, it is easy to visually determine which driving mode is selected and used.
