3 (a) and 3 (b) are output characteristic curves of the initializer circuit section of FIG. 1 and waveform diagrams of clear pulses obtained by differentiating the outputs thereof.

4 is a preset timing chart for explaining the operation of the preset portion in FIG.

The present invention particularly relates to a program reproducing apparatus suitable for an automatic selection apparatus of a tape recorder.

In recent years, the so-called radio cassette (redio cassette) that incorporates a radio receiver in a tape record order is rapidly spreading. Also in this kind of radio sub-recorder, large output, hi-fi and multi-function are required.

Meanwhile, in the field of audio equipment, it is desired to be able to reflect the intention of participation of the user itself, and among them, so-called karaoke (kaaaoke: background or chestra without singiugmelody) is causing an all-boosting.

For this reason, it is required to be able to show a karaoke function simply also in the above-mentioned radio tape recorder. In this case, the tape recorder can be relatively easily coped with a conventionally known tapping device and an automatic selection device which is one type of program reproduction device that has developed it.

However, it is not just to be able to cope with the karaoke function, and it can also be easily realized with a limited constant space and with a simple configuration as well as an affordable price, and the operation function is simple and reliable. There is no saying that it must be achieved.

By the way, the conventional automatic selection apparatus counts substantially the detection signal in the grain stem detection part which detects no signal part of a grain stem, and compares this count value with the setting value set by the grain number setting part, It was configured to automatically select the desired song set in the song number setting section by the coincidence signal from the temporal detection that actually matched, and above all had the drawback that the composition of each part was complicated and the operation was too complicated. . Here, the automatic selection operation is to send the tape at high speed (fast forward, rewind) until the designated song, stop sending at a high speed when the specified song comes to the fixed speed playback It is done by switching.

The setting section itself of the music selection operation may be set in a so-called up-down manner by successively pressing up or down setters, and selecting a plurality of setters and setting them in one-touch type. This is, of course, convenient for the latter, so that as many touch (button) switches are provided as the number corresponding to the number of songs, the physical space is limited so much that there is a drawback that the number of selectable songs is easily limited. In this case, it can be seen that once the selection is made to the maximum number of songs that can be selected, the operation of repeating the selection process again with a different tape position is repeated, but it cannot be denied that it is very complicated.

In addition, when the automatic selection function is enabled, it may be considered to omit this completely or to coexist both functions in a separate configuration for the conventional tapping function, but it is inconvenient in the former and uselessly long in the latter. It had the defect that it became the constitution.

For this reason, it has been requested to be able to provide convenience in terms of operability and to simplify the configuration by organically configuring the stroke function and the automatic selection (generally, program reproduction) function.

Therefore, in view of the above, the present invention is particularly limited in space, and has a simple configuration, and as simple as possible, can be easily realized with a low cost, and also easy and reliable operation of the program reproducing apparatus desired It aims to provide.

That is, when applied to the automatic selection apparatus of the tape recorder, the program reproduction apparatus according to the present invention substantially counts the detection signal from the intermission detecting unit that detects the intermission (no signal) portion of the tape which is initially sent at high speed. By switching the tape from high speed to constant speed by the matching signal from the coincidence detection unit which compares the count value and the setting value set in the song number setting unit, it automatically selects and plays the designated song number set in the song number setting unit. In this case, for example, the first sub-setting part and the first sub-setting part which have five setters that can be designated independently, for example, 1, 2, 3, 4, and 5, are assigned. A specific song number, such as the maximum number in the first sub setting unit, is added to the song number designated by the sub setting unit algebraically as needed. By configuring as a second sub-setting unit having a setter that can be specified, for example, all six setters have 1 to 5 and 1 + 5 = 6, 2 + 5 = 7... … All 5 + 5 = 10 allows you to set the curve of 10 arbitrarily.

That is to say, in general, a tape is played from fast playback to constant speed playback by substantially matching the data executive signal obtained by high speed playback of a plurality of pieces of data and a desired data value set in advance. In a program reproducing apparatus which is switched to automatically select and reproduce desired data, the desired data number setting section is 1, 2,... … Maximum number in the first sub-setting section that is added algebraically as needed to the first sub-setting section and the data number specified in the first sub-setting section with a plurality of setters that can independently designate a consecutive data number of n. and it is connected to the input end of the comparison driving circuit 18 to be described later via the resistor R ₁₀ a ⁺ n specific data time as at the same time as connected to the power supply + B through the anode and the common resistance R ₉ have the assignable setter .

The flip-flop FF ₆ is connected to its normal output end Q and its input end (corresponding to Q of FF ₁ ) corresponding to each cathode, and each anode is connected to the power supply + B through the resistor R ₁₁ in common. A repeating instruction unit for instructing the repeating operation to the shift register SR together with a switching circuit 16 of diodes D ₆ and D ₇ directly connected to the input end D at the _first end FF ₁ of the shift register SR ( 19).

This comparative driving circuit 18 as soon the base is connected to the resistance R ₁₀ at the same time the emitter capacitor to the collector of the power source + B the addition the collector is grounded via the resistor R ₁₂ to the transistor Q ₃ and the transistor Q ₃ C ₆ in at the same time as the resistance R ₁₃ between the base is connected transistor Q ₄ and the transistor Q _4, the base is connected via a resistor R ₁₄ to the collector - the via base is connected as soon while the emitter is connected to the power supply + B addition emitter The emitter is grounded and connected to the power supply + B via leaf switches SW ₇ and SW ₈ in conjunction with the fast forward and rewind controls of the high speed system in the coil and tape recorder mechanisms of the collector plunger PL. As the terminated transistor Q ₃ . The movable iron core of the plunger PL is connected to an operation unit of a high speed system (fast forward, rewind) in the tape recorder mechanism as described later, and is used to release only the high speed system during operation.

로 하는 것이다.In the figure, SW ₉ and SW ₁₀ are the high-speed fast forward and rewind operation units of the tape recorder mechanism. Each of the stages is connected to the power supply + B and the other stage is common. First, the emitters of the transistors Q ₆ constituting the preset circuit 21 are connected via the differential circuit 20 serving as the capacitors C ₇ and R ₁₅ . The transistor Q ₆ is connected to the preset terminal Pr of the terminal FF ₁ in the shifter resistor SR via the diode D ₈ of the polarity _shown by the collector, and the base thereof is connected to the comparison drive circuit through the resistor R ₁₆ . It is connected to the collector of the transistor Q ₃ in (18). In this case, first, the preset circuit 21 is a preset for automatic selection as described below, and preferentially designates the song number so that a normal (one song) export function can be performed when the song number is not designated.

It is to be.

In the above description, it is assumed that the clock terminal CK of the flip-flop FF ₆ and the cooler terminal CL are connected in parallel to the corresponding terminals CK and CL of the first end FF ₅ of the shift register SR described above, respectively.

And a system example of a system of the +5 preset switch SW ₁ -SW ₆ and the display light emitting diode LED ₁ -LED ₆ in the second part setting. In addition, the 2 LED _7, LED ₈ in Figure is to the diode indicating the normal and reverse (正逆) of the tape running direction.

Next, the operation of the automatic selection device configured as described above will be described. A recorder having this type of device can be locked at an operation position by a plurality of operators at one time, It goes without saying that the lock mechanism is provided so that other operators are released while leaving only a predetermined operator.

That is, in this case, in order to perform automatic selection, first operate the playback operator of the shape recorder (in the case of a radio tape recorder, turn on the power switch, and then set the function switch to the tape mode). By this, a predetermined power supply voltage is applied to the power supply + B to enable the preservation for automatic selection, that is, the music number assignment operation of the desired music.

If the start position of the tape is known in advance before such playback operation, it is possible to move to the pre-serving operation for automatic selection immediately, but in general, the tape is often wound freely. If the position cannot be known in advance, the playback state is continued as it is, and the first and second sub-setting portions of the current tape are configured. … n, 1 + n, 2 + n,... … The data number of 2xn-1 and 2xn can be arbitrarily set, and the feature of the present invention is that the number of data can be set as much as possible with a few setters. Next, with reference to the drawings will be described in detail the case applied to the automatic selection device of the tape recorder as one embodiment of the present invention.

That is, in Fig. 1, reference numeral 11 denotes a grain stem (generally between data) detecting portion of the grain stem of the playback system of the tape recorder, for example, a saturation amplifier, rectifier circuit, and Schmitt circuit. In this configuration, a pulse signal is output for each grain stem (data-to-data) portion. The output end of the inter grain difference detecting section 11 is connected to the clock terminal CK in the 5-bit shift register SR constituting a part of the music number setting section through the differential circuit 12 serving as the capacitor C ₁ and the resistor R ₁ . At the same time, it is connected to the parallel serial cutting terminal P / S of the shift register SR via the preset delay circuit 13 serving as the capacitor C ₂ and the resistor R ₂ and the diode D ₀ of the polarity shown.

Here, the 5-bit shift register SR is composed of five-stage subordinate flip-flops FF ₅ to FF _1. For convenience, they are treated as if they are integrated into ICs. The switching terminal P / S and the collier terminal CL are displayed only at the ultra high end FF ₅ , and the normal output terminal Q is displayed only at the end FF ₁ .

As described later, the shift register SR functions as a serial mode at the time when the parallal serial switching terminal P / S becomes a high level H and when the count is a low level L. .

The first part setting part is connected to each of the stages of the preset switches SW ₅ to SW ₁ correspondingly connected to each other and the respective anodes of the diodes D ₅ to D ₁ correspondingly connected to each other. Configure. Here, the other ends of the preset switches SW ₅ to SW ₁ are commonly connected to the power supply + B. The cathodes of the diodes D ₅ to D ₁ are connected in common and then connected to the shift register SR and the para-serial switching terminal P / S through the differential circuit 14 as the capacitor C ₃ and the resistor R ₃ . It is connected to the clear terminal CL of the shift register SR via the differential circuit 15 serving as the capacitor C ₄ and the resistor R ₄ . In addition, the output terminal of the initializer circuit 17 described later is connected to the common cathode of the diodes D ₅ to D ₁ through a coupling circuit constituted by the capacitor C ₅ and the resistor R ₅ .

Here, the initializer circuit 17 is composed of NPN and PNP transistors Q ₁ and Q ₂ that have a bias resistor R ₆ -R ₈ between + B and ground and are called PNPN connections (commonly referred to as SCR connections).

의 연번을 독립하여서 표시가능하게 하게 하기 위한 발광 다이오드 LED₅-LED₁의 각 캐소우드가 대응하여서 접속된다.In this case, the inverse output terminal Q at each stage FF ₅ to FF ₁ of the shift register SR is

The flip-flop FF ₆ is connected to the preset terminal Pr, in this case, the number specified by the preset switches SW ₅ to SW ₁ .

A second subsidiary government is formed by connecting one end of the preset switch SW _{8 that} can assign a specific song number +5 to a logarithmic value of 5 anywhere. In addition, a cathode of the LED LED ₆ capable of displaying a specific song number +5 is connected to the reverse phase output terminal Q in the same manner.

Here, the other end of the preset switch SW ₆ is connected to the power supply + B in common with the other ends of the preset switches SW ₅ to SW _{1 described} above. Also after checking the angular position of said one light emitting diode LED _{5 1} -LED lifting know-Ke of the light emitting diode LED ₆ is more convenient for performing a preset operation.

In this case, the desired song number can be set in the first sub setting section.

If any of

The preset numbers SW ₅ to SW ₁ that can be specified independently can be selected, but if the desired song number is any of 6-10, the sequence number specified by the preset switches SW ₅ to SW ₁

It is necessary to operate the preset switch SW ₆ of the setting part of the second part which has the meaning of adding 5 algebraically to the part of which is able to designate a specific song number +5, and 1 + 5 = 6, 2 + 5 = 7, 3+ 5-10, 4 + 5 = 9, and 5 + 5 = 10 to store 6-10.

Next, the case where the 3rd and 8th songs are designated as a specific example is frosted.

의 프리세튼 스위치 SW₃을 조작한다. 이에 의하여 시프트 레지스터 SR의 3단째 플립플롭 FF₃의 프리세트 단자 Pr에 전원 +B 전원이 공급되어서 당해 3단째 FF₃가 프리세트된다. 그러면, 이 3단째 FF₃의 역상출력단부 Q는 로우레벨로 되기 때문에

표시용의 발광 다이오드 LED₃이 점등구동되어서 3 3즉째곡에 프리세트 되었다는 것을 표시한다.If you specify the third song first

The operation of the pre-seteun switch SW _3. As a result, the power supply + B power supply is supplied to the preset terminal Pr of the third-stage flip-flop FF ₃ of the shift register SR, and the third-stage FF ₃ is preset. Then, the reverse phase output terminal Q of the third stage FF ₃ goes low.

The light emitting diode LED ₃ for display is turned on to indicate that it is preset to the third music.

In this state, the fast forward operator of the tape recorder is operated to bring the tape recorder to the high speed sending state. In other words, in the normal fast forward state, the head is retracted and the tape signal for intermission detection cannot be reproduced. Thus, the high-speed sending state is made in the reproducing state.

As a result, the pulse shape signal as described above is output by the grain stem (no signal portion) detecting section 11 for each grain stem of the tape. This intermission signal is waveform-formed by the differential circuit 12 and applied to the cool-lock terminal CK of the shift register SR. As described above, the shift register SR becomes a parall (parallel) mode at the time of presetting and a serial (serial) mode at the time of counting (this control will be described later). The preset flip-flop (in this case, FF ₃ ) is shifted to the rear flip-flop whenever the intermission signal is applied. In this case, the first intermission sub-signal is shifted from the third stage FF ₃ to the fourth stage FF ₂ , and the _second intermission portion signal is shifted from the fourth stage FF ₂ to the fifth stage FF ₁ .

Light-emitting diode LED ₂ for display lights up, then

LED LED ₂ for display turns off

The light emitting diode LED ₁ for display is turned on to indicate the progress (the number of music remaining until the desired music) on the way.

표시용의 발광 다이오드 LED₁이 소등된다.Then, when the third grain stem signal comes, the content of the fifth stage FF ₁ is reversed.

The light emitting diode LED ₁ for display turns off.

Then, since all of the light emitting diodes are turned off at this point, which one of the light emitting diodes is always in the lit state after being preset, the comparison driving circuit 18 operates. In this state, the flip-flop FF ₆ is not involved in any action by the action of the switching circuit 16 as the diodes D ₆ and D ₇ described later.

Here, the synchronism of the comparison driving circuit 18 will be described. As described above, any of the light emitting diodes in the lit state is turned on by the driving current, so that all the diodes Q ₃ The lamp is turned off to be turned off because the drive flow is lost. Then, the transistor Q ₄ that copes here is turned on from off, and therefore the transistor Q ₃ is turned off from on. As a result, the plunger PL slowed down to the collector circuit of the transistor Q ₃ is in a state where washing is applied through the leaf switch SW ₇ which is in the closed state, and the movable iron core is described in the tape recorder mechanism as described above. Only the fast forward operation unit is released, and the operation is made to switch to the reproducing state by stopping the high speed sending.

In this way, the reproduction is none other than the eighth preset song, which enables automatic selection (reproduction) of a desired song.

의 프리세트 스위치 SW₃을 조작하고 그후에 제2부설 정부의 +5 프리세트 스위치 SW₆를 조작하여 주면된다. 이것은 후술하는 클리어 동작에 의하여 +5+를 먼저 조작하면

을 조작한 시점에서 +5+의 프리세트 상태가 클리어 되어버리도록 되어져 있기 때문이다(다른 경우도 같다).When the eighth is specified next, the first sub-setting section

Operating the preset switch SW _3, and thereafter operates the main surface is +5 preset switch SW ₆ of the second laid state. This is because +5+ is first operated by the clear operation described later.

This is because the preset state of +5+ is cleared at the time of operation (other cases are the same).

의 프리세트 상태 및 그것에 의한 자동곡선의 도중 경과는 상기한 바와 동일하고, +5+의 프리세트와 동시에 +5+표시용의 발광다이오드 LED₆가 점등 구동되어져 있는 것만이 다르다.in this case

The preset state and the progress of the automatic curve by the same are as described above, except that the light emitting diode LED ₆ for +5+ display is turned on and driven at the same time as the +5+ preset.

발광 다이오드 LED₁이 소등되고 +5 의 발광다이오드 LED₆만이 점등되어 소당하는 곡까징 나머지가 5곡이라고 하는 것의 도중 경과를 표시하고, 3번째의 곡간부 신호로서 FF₆이 반전되기 때문에 +5의 표시자체는 꺼지나, 이번에는 그와 동시에

의 표시용 발광다이오드 LED₅가 점등하는 것에 의하여 동작이 계속된다.Then, when the second intermittent signal in the middle of the automatic curve as described above is received, the normal output end Q of FF ₁ and FF ₆ together becomes high level, and at least one of which is in the on state until then is switched. Since the diode switches D ₆ and D ₇ of the circuit 16 are turned off together, the power supply + B voltage is applied to the input terminal D of the shift register SR through the resistor R ₁₁ and at the same time FF as the third intermittent signal. _Is shifted from ₁ to FF _{6. During} this second to third intermittent signal,

Light-emitting diode LED ₁ is turned off and only +5 light-emitting diode LED ₆ is turned on to indicate the progress of 5 songs remaining, and FF ₆ is inverted as the third interlude signal. The indicator itself turns off, but this time

The operation is continued by the light emitting diode LED ₅ being displayed on.

That is, the human being is supplied with the high level of + B voltage at the input terminal D in the first stage FF ₅ of the shift register SR by the action of the switch circuit 16 as the diode switches D ₆ and D ₇ as described above. As a result, a kind of ring counter circulating function is performed, as if shifted from FF ₆ to FF ₅ .

It is shifted from FF ₅ to FF ₄ as the _fourth intermission signal, shifted from FF ₄ to FF ₃ as the fifth intermission signal, and FF ₃ -FF ₂ -FF by the sixth and seventh intermission signals. _The comparison driving circuit 18 operates by shifting in the order of ₁ and turning off all the feet and the diodes by turning the contents of FF ₁ as the eighth signal and the same as that described below. (Playback) operation is performed.

In this case, since FF ₆ is inverted and the normal output terminal Q is at a low level, the switching circuit 16 again prevents the circulation function.

In addition, it is obvious that the case of designating music numbers 1, 2, 3, 4, 5 and 6, 7, 9, and 10 other than the third and eighth songs can be similarly described in accordance with the above-described cases.

The above description is for the case where the playback operator and the fast forward operator are combined, i.e., how many songs in the forward or backward position from the current tape position are the same, ie how many songs in the reverse direction from the current tape position. The same applies to the automatic selection operation when there is a desired song in the front. In the latter case, however, the grain cue signal is detected at the grain top of the grain (the former is the grain bottom of the grain). . That is, in this case, the first intermission signal is obtained from the granularity of the current song. Therefore, when specifying one track ahead, it is possible to make the reproduction state from the one ahead of the first tune in the same manner as 1 + 1 = 2.

Advantageously, in the former case, the grain stem signal obtained as the arrival of the current song is obtained from the winning part of the next song, so that the desired song number can be set as it is without correction.

In the case of making the tenth or more song numbers (11, 12, ...) into a desired song, the tune is automatically selected as a preset to the tenth song, and the remaining number of songs from the tenth song to the desired song (less than ten) is selected. It may be set again, but since it usually takes a random playback position as a tape that contains 14 songs, most of them will not need to do this.

However, when using a tape that contains more than 14 songs, the setting part that can specify a specific song number + N, which has the meaning of applying algebraically to the serial number designation part such as +5, for example +5 N '+10 can be installed in multiple numbers, such as +10 to use the setting part of +5 together, and up to 11-15 to use the +10 setting part together, and again to 16-20 to +5 and +10 By using the setting unit together, the operation can be preset up to the 20th song in one operation.

In this case, as in the case of n = 5 and + N-5 of the above example, if n = N, it is reasonable and convenient to preset 1-10 in one operation, and N'-2N (= 10) is reasonable for the preset of 1-20, but can be any number without being limited thereto, and may be 1-n, + N, + N ', + N "……. will be.

로 하여 버린다고 하는 것이다. 즉, 상기한 바와 같이 이와같은 경우에는 통상의 (1곡)두출 기능을 나타낼 수 있도록 한 편이 편리하기 때문이다.Next, the operation of the preset circuit 21 will be described first. This means that after operating the playback operator, the operator immediately operates the fast-wooward operator or the rewind operator without performing the preset operation for the automatic curve as described above. Automatically resets the preset value if

It is said that. That is, as described above, in this case, it is convenient to be able to exhibit the normal (one song) stroke function.

의 표시용 발광 다이오드 LED₁이 점등하고, 1번째의 곡간부 신호가 오면 상기한 바와 같이 동일하게 동발광 다이되드 LED₁을 소등하여 고속상태에서 재생상태로 절환하여서 소위(1곡) 두출 기능을 영위하는 것이 가능하게 되는 것이다. 단, 리와인드 조작자를 조작하였을 경우에는 상기한 것과 같은 이유에 의하여 현재의 곡의 머리부터 재생되도록 한 소위 레뷰(Review) 기능으로 되나, 어떻게하든지 1곡 앞의 머리에서 재생하고 싶을 경우에는 이 시점에서 재차 리와인드 조작자를 조작하여주면 된다.That is, in this case, if the fast forward or rewind operator is operated immediately without performing the preset operation for automatic selection after operating the playback operator, either of the leaf switches SW ₁ , SW ₁₀ and the differential circuit 20 Since the transistor Q is turned on momentarily through, the preset essential is supplied to the preset terminal Pr of the fifth stage FF _{1 in} the shift register SR via the diode D ₈ . And by this

When the light emitting diode LED ₁ of LED lights up and the first intermittent signal comes, the same light emitting die LED ₁ is turned off in the same manner as described above to switch from the high speed state to the regeneration state to perform the so-called (one song) tapping function. It is possible to live. However, if the rewind operator is operated, it is a so-called review function that allows the current song to be played from the head of the current song for the same reason as described above. You can operate the rewind operator again.

에 자동적으로 프리세트되는 것은 자동선곡을 위한 프리세트 조작이 되어지기 이전뿐만이고, 만약 그것이 되어져 있을 경우에는 트랜지스터 Q₆에 의하여 금지된다. 즉, 이 트랜지스터 Q₆의 베이스 전위는 비교 구동회로(18)에 있어서의 트랜지스터 Q₃의 에미터 전위로서 다해 트랜지스터 Q₃이 상기한 바와 같이 프리세트 되어 있어서 어느 것인가의 발광 다이오드가 점등상태에 있으면 온 상태에 있으므로, 이때의 에미터 전위에 의하여 역바이어스 상태로 되어지기 때문이다. 바꾸어 말하면, 프리세트 조작전에는 트랜지스터 Q₃이 오프되므로 트랜지스터 Q₆의 베이스 바이어스가 순바이어스 상태에 있으므로 상기한 바와같은 패스트 포오워드 혹은 리와인드 조작자에 의한

에의 우선 프리세트가 가능하게 되는 것이다.First, the preset circuit 21 is as described above.

It automatically and before it is the preset operation for the automatic selection of music that is pre-set as in, if it has been that it is inhibited by the transistor Q _6. In other words, the base potential of the transistor Q ₆ serves as the emitter potential of the transistor Q _{3 in} the comparison driving circuit 18, and the transistor Q ₃ is preset as described above. It is because it is in an on-bias state by the emitter potential at this time since it is in an ON state. In other words, since the transistor Q ₃ is turned off before the preset operation, the base bias of the transistor Q ₆ is in a forward biased state, so that the fast forward or rewind operator described above is used.

Preferred presetting is enabled.

Next, various circuit operations are described in which the above-described automatic pole operation is made satisfactory without contradiction and without malfunction.

First, the initializer circuit 17 will be described, which is intended to solve the inconvenience caused by the gentle granularity of the power supply at the time of power supply. That is, each flip-flop FF ₁ -FF ₆ of the preset part is cleared immediately after the power is turned on, so that all of the light emitting diode LEDs _1- LED ₅ are turned off, thereby requiring the preset standby state.

However, if the initializer circuit 17 is not used, since the power supply is smoothly formed, the state of each flip-flop does not become constant, and there is a inconvenience that it cannot be cleared on the spot. Thus, the initializer circuit 17 converts a gentle power supply into a pulsed pulse by the NPN and PNP transistors Q ₁ and Q ₂ connected to the 4-layer PNPN (so-called SCR connection). By using it as a clear pulse, it becomes possible to eliminate the above inconvenience. In other words, NPN and PNP transistors Q ₁ and Q ₂ connected by a four-layer connection of PNPN have the same vertical shape as the solid line shown with respect to the power granularity characteristic (a) of the dotted line shown in Fig. 3 (a). to as to have the output characteristics (B) to the particulate trigger level of the output characteristic (b) is determined as a base voltage V _be of the PNP transistor Q ₁ side. 3 (b) shows a waveform in which the output of the riser circuit 17 is a clear pulse through the differential circuit 15. When this clear pulse is supplied to each of the clear terminals CL of the flip-flops FF _{1 to} FF ₆ when the power is turned on, the initialized stable clearing action can be performed.

In addition, when the clear operation according to the preset operation is explained, it is made through the diodes D ₁ -D ₅ connected between the respective preset switches SW ₁ -SW ₅ and the clear terminal CL of each flip-flop FF ₁ -FF ₆ . To lose. That is, when operating the one preset switch (to be described later is to exclude only SW _6), will be given here for the clear pulse to flip-flop, except that the flip-flop corresponding to the via any one of a diode.

Thus, when correcting the preset numerical value, the previous preset value can be cleared by simply setting the numerical value again without requiring a dedicated clearance position.

의 프리세트 스위치 SW₁-SW₅의 어느 것인가를 먼저 조작한 후에 조작할 필요가 있다는 것은 이클리어 동작때문인 것이다. 즉 +5의 프리세트 스위치 SW₆를 먼저 조작한 후

의 프리세트 스위치 SW₁-SW₅의 어느 것인가를 조작하면, +5의 프리세트 치가 클리어되어 버리기 때문이다. 반대로

의 프리세트를 먼저 조작하고 +5의 프리세트를 뒤에 조작하였을 경우에는 프리세트 스위치 SW₆에는 클리어용의 다이오드가 접속되어 있지 않으므로 하등 클리어되는 일 없이 그대로

의 어느 것인가와 +5의 프리세트가 되어지는 것이다.By the way, when operating the preset switch SW ₆ of the second sub-set portion +5 as described above, the first laying government

It is because of the clear operation that one of the preset switches SW _{1 to} SW ₅ needs to be operated first. That is, first operate the +5 preset switch SW ₆

This is because the +5 preset value is cleared when any of the preset switches SW _{1 to} SW ₅ are operated. Contrary

If the preset is operated first and the +5 preset is operated later, the clear switch is not connected to the preset switch SW ₆ , so it is not cleared at all.

Which will be a +5 preset.

This is preferable in that it is easy to change a preset without providing a dedicated clear (button) switch as described above.

Incidentally, although the shift register SR can be used as the parallel mode at the preset time and as the serial mode at the time of counting, the control operation of the serial parallel switching will be described. In other words, when any _{one of the} preset switches SW _1- SW ₅ is operated, it is applied to any of the diodes D ₁ -D ₅ and the differential serial switching terminal P / S of the shift register SR through the differential circuit 14. The parallax mode is set by the high reel voltage, and the serial mode is set at the time when the high level voltage disappears and becomes low level.

When any _{one of the} preset switches SW _{1 to} SW ₅ is operated, each of the flip flops FF _{1 to} FF ₆ is _first cleared as described above, so that each of the flip flops FF _{1 to} FF ₅ can be actually preset. It is after this clearing period. In the case of presetting, the shift register SR functions as a pararell mode when the high level is controlled by the control of the pararell serial switching for the shift register SR as described above. There is a need.

It is the preset delay circuit 13 that ensures the timing of such a preset, whereby the preset pulse obtained by the delay can be surely preset.

4 shows the timing timing of the preset as described above, (a) is the timing of the preset switch operation, (b) is the timing of the pararell serial switching control signal generated by the preset switch operation, (c ) Denotes the timing of the clear pulse, (d) shows the timing of the preset pulse accompanied by the delay, and (e) indicates the timing of the intermission signal which becomes the clock pulse.

It goes without saying that the present invention can be modified in various ways without departing from the gist of the present invention without limiting the above-described and illustrated embodiments.

For example, in the above, the preset setting unit is not limited to the combination of the shift register SR and the flip-flop FF ₅ , but may be a counter (including a ring counter). In comparison, the tape drive mechanism is controlled by switching from high speed transmission to constant speed transmission. The preset display unit is not limited to a light emitting diode but may be another display element such as a lamp.

In addition, the present invention is particularly suitable for applying to an automatic selection apparatus of a tape recorder, but of course, the data recorded on the tape may be different from music (songs) or widely applied to a general apparatus for handling the tape. In this case, each of the grain cubic part signals is an inter-data signal, and the inter-signal signal is not limited to detecting a no-signal part (blank), but to detect main data and other identifiable signals (data). It may be.

Therefore, as described above, according to the present invention, the desired data number setting section is 1. … the first data set part having a plurality of setters that can be independently set to n, and the maximum data number in the first part set part added algebraically to the data number specified in the first sub set part as needed; By configuring the same specific data number + N as a second setting unit having a settable designator, as many data sets as possible can be set with a small number of setters, whereby a limited number of data can be set as possible. It is possible to provide an extremely good program reproducing apparatus which can be easily realized at a low cost and can be easily realized, and whose operation can be easily and surely desired.
