The present invention provides multiple song selection functions in one with the addition of only a few parts.
The present invention relates to a multiple song selection prohibition circuit of a cue selection device that switches to a song selection function. Recently, there has been a trend to add a skipping function for selecting the beginning of a song to tape players. What is cue selection? Detects unrecorded parts (intervals) between songs in fast forward (FF) or rewind (REW) mode, and cancels FF or REW when the number of intervals reaches the set number. The function is to start playback (PLAY) from there.There are the following methods for this song selection operation. (1) “1
If you turn on the song selection switch and then turn on the FF/REW switch, the performance will resume from the position where the song interval was first detected. (2) One method of "multiple song selection",
Turn on the cue selection switch multiple times, then
When the FF/REW switch is turned on, the performance is restarted from the position where the song interval has been detected as many times as the song selection switch has been operated. (3) Use another method for "multiple song selection" to turn on the cue selection switch to enter cue selection mode, then enter the number of skipped songs using the 10 (numeric) key, etc., and finally turn on the FF/REW switch. When turned on, the performance will resume after skipping the number of songs entered using the 10 key etc. Among the above-mentioned song selection methods, (3) multiple song selection requires a 10 key to enter the number of skipped songs, but (1)
and (2), all you need is a cue selection switch.
If the device is capable of performing multiple song selections in (2), the operation of pressing the cue selection switch only once is no different from the one-shot song selection in (1). Therefore, the cue selection devices (1) and (2) use most common parts, and by slightly different parts, it should be possible to differentiate their music selection functions. It has great merits such as reduced manufacturing costs. The present invention has been made in view of the above-mentioned points, and attempts to switch the music selection device to a single song selection type by simply adding a circuit for inhibiting multiple song selection, which is a simple circuit component, to a music selection device having a multiple selection function. It is something. That is, the multiple song selection prohibition circuit of the present invention has a multiple song selection function that specifies the number of songs to be skipped by turning on the cue selection switch multiple times, and specifies the direction in which to skip by turning on the fast forward or rewind switch. In the music selection device, an electronic switch is connected in parallel to the music selection switch, and the electronic switch is turned on by an internal signal that changes from the time the music selection switch is pressed until the music selection operation is completed. However, this will be explained in detail below with reference to the illustrated embodiment. 1 and 2 are diagrams showing one embodiment of the present invention, and FIG. 1 shows a tape deck control device using a microcomputer. The control device is pre-equipped with a multiple song selection function. That is, in the figure, IC 1 is a 4-bit, 1-chip microcomputer, which has internal RAM, ROM, CPU, and I/O ports. IC 2 is a decoder driver that converts BCD (binary coded decimal) codes into seven-segment signals for digital display (numbers). IC 3

下表に示す。[Table] However, the R terminal is a reference voltage input, and the rail motor MOT 1 changes its rotation speed in proportion to this input voltage. IC 4 is an IC that controls the capstan motor MOT 2 , and its truth values are the same as in Table 1.
However, since the R terminal is grounded, motor MOT 2 rotates at a constant speed. PLN 1 is an electromagnetic solenoid that drives the mechanism that loads and ejects the cassette pack, and PLN 2 is the mechanism that moves the magnetic head toward and away from the magnetic tape surface in the pack, and the pinch roller that moves the pinch roller toward and away from the capstan. This is an electromagnetic solenoid that interlocks and drives the mechanism. RL is a relay that switches between A track and B track (described later) of the magnetic tape, T r1 is a transistor that drives plunger PLN 1 , and T r2 and T r3 are plunger PLN 2.
T r4 is a transistor that provides high and low binary reference voltage to the six terminals of IC 3 ,
BUF is buffer, D is diode, L 1 to L 5 are
AUTO-J (start selection), FF (fast forward), REW
These are light emitting diodes that display (rewind), run A, and run B. The inputs of the microcomputer IC 1 include a delayed reset signal RST from the integrator circuit INT when the power is turned on, and 16 inputs K 0 to K 3 from the key matrix KM according to timings 1 to 4 .
There are reel rotation detection signals A, B, audio signal, and the output is AUTO.
- There are 18 ways from J to MUTE. The key matrix KM is a 4×4 matrix as shown in Fig. 2, and among the switches S 01 to S 34 at each intersection, S 03 ,
S 04 , S 13 , S 14 , S 21 , S 23 , S 24 , S 32 , and S 33 are manually operated, and the rest are linked to the movement of internal mechanisms or other mechanisms. The on states of these switches are read by scan signals 1 to 4 having different phases from the microcomputer IC 1 .
For example, switch S 04 is turned on and output K 0 is turned on at timing 4 . At this time, switches S 14 , S 24 , and S 34 are off, so K 1 ~
K 3 never turns on and switch S 01 ~
Since S 03 is off, K 0 at timing 1 to 3
never turns on. Among these, the switches used in the cue selection operation are the FF switch S 13 , the REW switch S 13 , the REK switch S 23 and the cue selection switch S 33 . On the other hand, the output AUTO-J is a signal indicating that cue selection is in progress, and the light emitting diode L1 lights up. FF and REW are 2Hz signals indicating fast forwarding and rewinding, and drive the light emitting diodes L 2 and L 3 to blink, respectively. Running A and running B indicate the running direction of the magnetic tape, and running diode L 4
lights up, and light emitting diode L 5 lights up in driving B. The song number displays A to C indicate how many songs are to be skipped when selecting the beginning of a song using 3 bits. The contents are shown in the table below.

If it is composed of only S34 , multiple songs can be selected, and the number of songs to be skipped is determined depending on the number of times the switch S33 is pressed. On the other hand, a multi-track prohibition circuit consisting of a transistor Tr and resistors R 1 and R 2
If INH is added, song selection is limited to one shot.
In other words, the transistor Tr is connected in parallel to the switch S33 , and the AUTO
Since it is controlled by the -J output or the track number display A output, as shown in Figure 3, when switch S 33 is turned on once, the falling edge is detected by IC 1 , and the AUTO
-J becomes "1" or the song number display A becomes "1", so the transistor Tr is turned on.
Since IC 1 only detects the falling edge of switch S 33 ,
Once the transistor Tr is turned on, the input of IC 1 will not change even if the switch S33 is turned on twice, three times, etc. In addition, AUTO-J and track number display A will remain on until the selection operation is completed, that is, switch S 13 or
Press S 23 and press “1” until cueing is actually completed.
Since the level is maintained, the number of songs selected by the switch S33 is ultimately limited to one regardless of the number of operations. FIG. 4 shows the operation flow for one song selection and multiple song selection, where --- indicates one song selection, and --- <--> indicates multiple song selection. The indicator at the beginning of the figure is the light emitting diode L 1 in Figure 1.
corresponds to The multiple song selection prohibition circuit INH in Figure 2 is the root −
− is forced. As described above, according to the present invention, by adding a small number of components to a cue selection device capable of selecting multiple songs, the song selection function can be limited to one song. Cost reductions are expected through mass production.
