Description

[Detailed Description of the Invention] ■Object of the Invention The present invention relates to an improvement in the mechanism of a tape recorder,
Proposes a tape mechanism devised so that the playback button can be controlled to first put the tape in a pause or playback state at the first push-in position, and then switch to the playback or pause state at the second push-in position,
The purpose is to propose a mechanism that does not require a pause button separate from a play button.

@ Outline of the mechanism according to the present invention The present invention has two embodiments as detailed below.

First, as shown in Figures 1 to γ, the first mechanism [■] first holds the playback button in the paused state at the first push-in position, and the second mechanism holds the playback state at the second push-in position of the playback button. Third mechanism E
It is equipped with l.

On the other hand, as shown in Figs. 8 to 10, part 2 is a first mechanism [D
and a third mechanism (2) for holding the regeneration button rod in a paused state at the second pressed position.

In either case, a second mechanism prevents the playback button from progressing so that each switching position is adopted in the second operation such as pause → playback or playback → pause, that is, playback is performed at once, or the playback button is prevented from proceeding to pause. [Provides a phase.

In addition, by pressing the playback button lever again from the second push-in position, it is configured to return to the first push-in position and return from playback to pause in the first embodiment, and from pause to playback in the second embodiment. has been done.

Furthermore, in either case, by operating the stop button, the playback button rod, which was in the playback or pause state at the first push-in position or the second push-in position, can be returned to the stop state.

0 Description of the First Embodiment The attached drawings show the main parts of the mechanism of the tape recorder.

(In both cases, the chassis is omitted to make it easier to understand the mechanism.

) From Stop to Pause By pressing down the playback button 1 from the stop position shown in FIG. It will be understood from FIG. 2 that the tip 3 of the button rod 2 is lowered and brought to the position shown in FIG. 2, but the blocking piece 5 of the blocking lever 4 prevents the regenerating button rod 2 from being pushed in further.

In this state, when the pressure on the regeneration button is slightly loosened, the blocking lever 4 is rotated counterclockwise due to its firing and becomes the state shown in FIG. The locking portion 6 of the button rod 2 and the locking piece 8 of the horizontal rod 7 come into contact with each other, and the reproduction button rod 2 maintains the paused state.

In this state, the pinch roller 9 does not come into contact with the capstan 10, and the drive shaft 11 also does not come into contact with the take-up reel stand 12. In other words, the electric motor (not shown) is energized by the electric switch 13. The tape is not running and is in a paused state.

From Pause to Playback By pushing the playback button 1 further downwards from the pause state shown in Figure 3, the tip 3 of the hook rod 2 can move down in the groove of the blocking lever 4, so that it will move downward as shown in Figure 4. The first lateral control piece 14 of the hook rod 2 is a pinch roller pivotally supported on a transition plate 15.
Rotate the rod 16 counterclockwise and press the pinch roller rod 16.
As a result, the extension portion 17 of the pinch roller 9 is also rotated.
is brought into contact with the capstan 10, and the pin 19 of the arm rod 18 on which the drive shaft 11 is mounted is brought into contact with the capstan 10 by the rotation of the extension portion 11.
1 in a clockwise direction to bring the drive shaft 11 into sliding contact with the reel stand 12.

At this time, as shown in FIG.
The hook rod 2 descends along the upper curved portion of the locking lever 23 and is locked by the hook portion 24 of the locking lever 23, so that the hook rod 2 maintains the regenerated state without returning.

From playback to pause If the playback button 1 is pressed again from the playback position shown in FIG. become.

This is because, in FIG. 5, when the control piece 22 and the hook portion 24 are slightly disengaged, the locking lever 23 is rotated counterclockwise by the spring.

Due to this change, the hook rod 2 is pulled upward by the spring and returns to the pose state shown in FIGS. 2 and 3.

From playback to stop Press the stop button 26 in Figure 4 to stop the playback 2.
Since γ pushes the release piece 28 of the horizontal rod γ to the left as usual, the locking lever 23 is moved from the position shown in FIG. 29 takes an inclined position against the spring, and the above-mentioned second side control piece 2
2 moves from the hook part 24 to the lower side of the cut-and-raised slope part 25 (Fig. 7) of the locking lever, and the hook rod 2 is no longer restrained by anything and returns to the stop position shown in Fig. 1. This can be fully understood from the attached drawings, and anyone skilled in the art who handles this type of tape recorder can understand that the pinch roller is naturally separated from the capstan, and the drive shaft is also separated from the reel stand. There is no need to add any additional information to the explanation.

From Pause to Stop By operating the stop button from the pause state (Fig. 2), which is the first push-in position, the first mechanism between the regenerating hook rod 2 and the horizontal rod 1 [the locking part 6 of the hook rod 2 and the horizontal Needless to say, the locking piece 8 of the rod 1 is released and returns to the stop position shown in FIG.

An appropriate button 30 located between the play button 1 and the stop button 24 in the figure
By adding marks for PAUSE and PLAY with an arrow above, in this embodiment, the button that is used for both operations can be used as a guide to know whether the button is in the pause position or the playback position.

The second embodiment is basically the same as the previous embodiment, except that the regenerating hook rod is held in the regenerated state in the first pushed position and locked in the paused state in the second pushed position. The order is reversed for the king's pedestal, and only some of the levers and armrests have been changed accordingly.

Therefore, the s, s, io diagrams correspond to the 1°2.4 diagram of the previous embodiment.

Parts with the same drawing numbers will be described with the same drawing numbers as in the previous embodiment.

From stop to play When the playback button 1 is pushed down from the stop position shown in FIG. The tip 3 of the hook rod 2 is brought to the position shown in the figure, but the blocking piece 5 of the blocking lever 4 prevents the regenerated hook rod 2 from being pushed in further.

(See Figure 9) When the hook rod 2 is pressed down, the transition plate 15 connected by the spring moves downward, and moves below the pinch roller rod 16 and its extension 17, which are pivotally supported thereon, and the pinch roller -9 is brought into contact with the capstan 10, and the drive shaft 11 is brought into contact with the take-up reel stand 12.

At this time, when the pressing force on the push button 1 is slightly weakened, the blocking piece 4 is rotated counterclockwise due to the spring, and the third
It assumes a position similar to that shown in the figure and enters a regenerated state, and in this state, the regenerated hook rod 2 maintains its regenerated state due to the contact between the locking portion 6 of the hook rod 2 and the locking piece 8 of the horizontal rod 1.

From playback to pause When the playback button 1 is pushed further downward from the playback state, the tip 3 of the hook rod 2 descends into the groove of the blocking lever 4, and the hook rod 2
As shown in FIG. 5 of the previous embodiment, the side control piece 22 descends along the upper curved portion of the blocking lever 23 constituting the third mechanism (2) of the present invention, and the hook of the locking lever 23 is moved downward. Part 24
The hook rod 2 remains in the pose state without returning to its original position.

At this time, the pin 29 (FIG. 10) on the button rod 2 presses down the second extension piece 17 of the pinch roller rod 16, causing the pinch roller rod 16 to rotate clockwise. Stan 10, drive shaft 11 and take-up reel stand 1
2 is disconnected and the mechanism enters a pause state.

From Pause to Playback To return to the playback state from the pause state described above, by pressing the playback button 1 again, the hook rod 2 will be slightly pushed back from the position explained in FIG. 5 in the previous embodiment. As a result, the side control piece 22 and the hook portion 24 of the locking lever are unlatched, and the locking lever 23 rotates clockwise to be located below its sloped portion 25. In the drawing, the hook rod 2 is spring-loaded (not shown) so as to escape upward, so if we explain using the drawings of the previous embodiment, it will return as shown in Fig. 6 → Fig. T, i.e. Although the third mechanism is disengaged and the hook rod 2 returns upward, the locking piece 8 of the horizontal rod γ comes into contact with the locking portion 6 of the hook rod 2, returning to the regenerated state shown in FIG. 9.

By pressing the stop button from playback or pause to stop, the horizontal rod is moved to the left, so if it is in the playback state, the first mechanism (1) will be removed, and if it is in the pause state, the third mechanism rule will be removed. is released and all mechanisms return to the stopped state shown in Figure 8.

Regarding both examples, Yokoyama of the 1st to 3rd aircraft [Regarding the relationship between the fence and the mark in each case, in the case of holding, blocking, and locking, there is an x mark, and in the opposite case, holding, blocking, and locking are released. The times are shown below with a ÷ mark added.

Effects that can be expected by implementing the present invention: According to the mechanism of the present invention, there is no need to provide a separate pause button, and the playback and pause states can be specified by operating - playback buttons, and the number of parts can be reduced. As for the operation, the pause state related to the playback state is associated with the playback button, which has the effect of making the use of the usage table convenient.
