Abstract

PURPOSE:To decrease intermittent time of a music tone by starting the release of the 1st transport after it is detected that the 2nd transport is operationable. CONSTITUTION:When the arrival of a leader tape section is detected by a leader tape detecting section 21 at a time t1, the 2nd transport 23 starts driving by a drivemeans 22 while the operation of the 1st transport 26 is continued, it is operated at a time t2 and the reproduction or recording is attained. When the operation enable state of the 2nd transport 23 is detected by an operation enable detecting means 24 at the time t2, the 1st transport 26 starts releasing and is released completely at a time t4. Then the muting is released at a time t3 by the 2nd transport 23 and the music signal is reproduced or recorded. Thus, intermitting time of the music is decreased.

Description

[Detailed description of the invention]. ,,) Brother 1□ (Yo, っ. か.□, 1st work'fjJ i□
, 7 Yogada.

The first transport and the second transport of a tape player housed in the same case are sequentially moved in sequence from the first transport to the second transport in a continuous product or reproduction work. The aim is to reduce the interruption time of the musical sound during the transition to BJ and J.
It is something that

Conventionally, in order to transfer the operation from the first transport to the second transport in this tape player device, the first transport is detected to have stopped operating, and the second transport is driven using this detection signal. was the majority.

Zunawaji, in the first transport) detects the stoppage of the briel or a change in the tape tension, and
When the head fixing plate of the transport is moved to the i9r position after sliding the head fixing plate of the transport to release the contact between the tape and the head, this is detected by a relay, etc., and then this detection No. 11 is used to detect the second transformer. Slide the plate towards the head of the port to the iJI position.Second!・Make contact between the transport tape and the head.

In addition, during this period, the capstan should be driven or stopped, the pinch roller should be moved, and the reel stand should be moved.
It is well known that ``1 order'' is carried out.

Expressing this for the 1st
The motion of the transformer fμ, (b) is the second transformer: "j
(C) indicates the presence or absence of action i.

Assuming that the time when one person takes out the + and 4 ends of the tape is [1], the first transport starts removing the body from [l and is completely removed by 11.(2).

Then, the 2 transport starts operating from [2,
(The operation ij itg occurs.

Also, [4 is the unpleasant sign in the 4th period of the second transport, 1 case of muting to remove, 1 time of urine>j<"it".

Therefore, the musical tone is interrupted from 11 to L4.

In addition to this, if the end of the tape is detected by stopping the block IJ or by increasing the tape tension, the running time of the leader tape is added to this, and the running time of the leader tape may be longer than before. Become.

In the case of transport, the head is fixed by a motor or the rotational force of the spindle motor is used to fix the head.
Due to the slow connection of Kari, it becomes longer in Rakushu's Naka lI, l11 Anma or Kari.

Therefore, in this invention, 441) After detecting -1:lI of the leak tape of the transport, the driving of the second transformer is detected, and after detecting that the second transformer has become operational. , the interruption time of musical tones is reduced by opening the release of the first transport i+Q-, and the embodiment will be explained in detail below.

In the first embodiment shown in the second example, 21 is a means for detecting the arrival of the leader tape, and specifically, it uses a first transistor and a light emitting diode to detect the light transmittance or separation between the tape and the leader tape. Detect changes in the bower.

Reference numeral 22 denotes means for rotating the second shaft port 23, which includes means for transmitting the rotational force of a spindle motor or a spindle motor for sliding the head plate.

24 is an operation 1""1 stop (fire 1"4) which detects that the +ij head fixing plate of the second transport 23 is in complete image contact with the tape and the head and the second transport 23 is ready for operation. It is a means.

1 tool IJ'J has a writing head lI8+1 hiki board or 1 si 1
This is a relay that when moved to the positive position by 1+'l, the hand is temporarily pressed and releases the circuit by 1".

2b is for releasing the first transformer il'--to 26 by the output of the 1jth detection stage 10 for l'l-! JA drive means - Thank you, 1llljC drive car 32 stages 2
A disaster similar to 2 will occur.

To explain the operation of the tape player μ of this invention by IIJ Sei with reference to FIG. 3, FIG. (C) shows the interruption of the beep.

When the leak tape detecting means 21 detects the arrival of the leak tape capital at t], the first transport 2 (
The second transport 23 hears the drive by the driving means 22 while continuing, and the playback or recording operation becomes [2] and the playback or recording operation becomes [1] b and 1. evening. □ When the operation OJ+il; of the second transport 23 is detected by the detection means 24, the first transport 26 starts to release, and the first transport 26 starts to release completely at [4]. +4. Hidden.

Also, in porridge 2 transport 23, 1IIJ at t3
(It's muting as if it were a trip) The eyes are urinated, and the musical tone No. 1 is played or played.

However, in this invention, the interruption time of Shibakubi is between [1 and t3.

At Ifushi Temple, the transport is driven, 1 da I! Since the muting time was approximately 0.4 seconds and the muting time was 0.2 seconds, in the conventional example, a 1- would occur during an interruption of approximately 1 second, but in this invention, this is reduced to 0.6 seconds. I was able to do that.

As is clear from the above Mengming, this invention can reduce the interruption time caused by the transition from the first transport to the second transport in continuous playback recording, and the discomfort caused by 1υ in +H. (This is a rather conventional invention, as it can reduce ■.
