Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pause device for a tape recorder that can temporarily stop the tape drive during recording or playback.

Recently, tape recorders are equipped with a pause device that temporarily stops the tape drive without operating the record button or playback button when you want to temporarily stop the tape running during recording or playback. However, the number of parts was large and the configuration was complex.

Furthermore, as a conventional example, Japanese Utility Model Publication No. 52-18091 describes a technique in which the tape drive is temporarily stopped by the ON-OFF operation of the main switch. When the PLAY button is operated while the main switch is in the non-operating position, one contact piece of the main switch is forcibly deformed and turned on, and when the pause button is operated in this state, the main switch Since the configuration is such that a forcible elastic deformation force is applied to the other contact piece to turn it into the OFF state, it is possible to operate the pause button and maintain this state continuously using a lock lever, etc. In this case, a forced elastic deformation force is always applied to the pair of contact pieces of the main switch, which creates a risk of damage to each contact piece of the main switch and also causes damage to the pair of contact pieces. There were drawbacks such as the inability to perform stable contact and separation operations.

The present invention has been developed in view of these points, and has realized temporary stop of tape drive with an extremely simple configuration.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 is a plan view showing the playback state, Figure 2 is a plan view of the main part showing the paused state, and Figures 3a and l) are side views showing the different states of the button/button lock mechanism of the pause lever. , FIG. 4 is a schematic motor power supply circuit diagram.

1 shown in the figure is a motor installed on the chassis 2,
Rotational driving force is transmitted from the motor pulley 3 to a flywheel 6 having a capstan 5 via a bell l-4.

Reference numerals 7 and 8 denote a supply reel holder and a take-up reel holder, to which rotational driving force is transmitted via an idler, respectively.

A head slide 9 includes a magnetic head 10, 11, a pinch roller 12, etc., and is slidably provided on the chassis 2, and is biased in the direction A by a spring 13.

Reference numeral 14 denotes an operating lever having an operating piece 15 that opens and closes a power switch, which will be described later, when a temporary stop lever, which will be described later, is in a non-operating position.Like the head slide 9, it is slidably provided on the chassis 2. At the same time, it is always urged in the direction A by the spring 16.

17 is a temporary stop lever that moves from a non-operating position to an operating position against the urging force of a return spring 18;
The temporary stop lever 17 is slidably provided on the top of the temporary stop lever 17.
is held in the operating position by a bushing/button locking mechanism 19.

Incidentally, since the bushing/bushing locking mechanism 19 is well known, a detailed explanation of its configuration will be omitted.

20 is a power switch mounted on the temporary stop lever 17, the first contact piece 21 is connected to the lead wire from the power supply positive terminal, and the second contact piece 22 is connected to the lead wire from the power supply negative terminal to the motor. connected via i.

Reference numerals 23 to 27 indicate operation levers for recording, rewinding, reproducing, fast forwarding, stopping, etc., each having hook portions 28 to 32, and are biased to slide in the A direction by respective return springs 33 to 37.

Of these, the operating levers 24, 25, and 26 have projecting shafts 38, 39, and 39 that push and slide the operating levers in the opposite direction of arrow A.
40 is provided, and a pressing shaft 42 is further provided on the reproduction lever 25 to press and slide the head slide 9 in the opposite direction of arrow A via a spring body 41 to bring it into the reproduction state.

43 is a lock piece 44 that locks the operating levers 23 to 26.
-47, is slidably provided on the chassis 2, and is always moved by the arrow B by a spring 48.
Forced in the direction.

The device of the present invention is constructed as described above, and its operation will be described below.

First, in the reproducing state shown in FIG. 1, as the reproducing lever is operated, the operating lever 14 slides forward in the opposite direction of arrow A via the protruding shaft 39, and along with this sliding, the operating lever 14 slides forward in the opposite direction of arrow A. The operating piece 15 of the operating lever is the first contact piece 21 of the power switch.
The first contact piece 21 is elastically deformed in the direction opposite to the arrow A, thereby opening the power switch 20 and supplying power to the motor 1.

At the same time, the press shaft 42 on the regeneration lever 25 causes the head slide 9 to slide forward in the direction opposite to the arrow A via the spring body 41 to bring it into the regeneration state.

Furthermore, when operating the rewind or fast-forward operating lever, the operating lever 14 is slid forward, so the first contact piece 21 of the power switch is elastically deformed to be in the open state, and the motor 1 is power is supplied.

Next, when the pause lever 17 is operated in the playback state shown in FIG. The power switch 20 is released by releasing the elastic deformation of the first contact piece 21 and the second contact piece 22.
is opened, motor 1 is stopped, and tape drive is temporarily stopped (see Figure 2).

Incidentally, the temporary stop lever 17 is held at the operating position by a bushing/bushing lock mechanism 19.

3A shows the state of the bushing-bush locking mechanism 19 in which the temporary stop lever 17 is locked, and b shows the unlocked state.

As described above, according to the device of the present invention, the temporary stop lever that moves from the non-operating position to the operating position is provided with a power switch that moves together with the lever, and the power switch is configured to close the tape when the temporary stop lever is in the non-operating position. It has a pair of contact pieces that come into contact with an operating lever that is operated by the lever when the playback lever of the recorder is operated, and are elastically deformed and change from an open state to an open state, and in this state, the pause lever is operated. The temporary stop lever is configured so that when the power switch moves to the position, the pair of contact pieces are separated from the operating lever and each contact piece is set to the open state due to the accompanying positional change of the power switch. Even if the power switch is operated and the state is continuously maintained using a lock lever, etc., no elastic deformation force is applied to the pair of contact pieces of this power switch; Therefore, it is possible to eliminate the risk of damage to each contact piece of the power switch, and at the same time, the pair of contact pieces can be stably connected and separated over a long period of time, and its effects have practical value. This is extremely high.
