Description

[Detailed Description of the Invention] The present invention relates to a tape recorder, and particularly relates to operation control between a tape recorder and other equipment related to the tape recorder, such as a tuner. Other devices such as the tuner can be operated in the stopped state, which is a non-operating state, but other devices such as the tuner cannot be operated when the tape recorder is in the playback state or in the fast-winding state such as fast forwarding or rewinding. let me,
When the tape recorder is in a recording state, other equipment such as a tuner is enabled so that signals from other equipment such as the tuner can be recorded.

Conventionally, when a tape recorder and another device such as a tuner are connected to each other, and the tape recorder is operated for playback or fast winding while the other device such as the tuner is in operation, the power to the other device such as the tuner is turned off each time. It was inconvenient as it required cutting.

The present invention solves such conventional drawbacks, and when the tape recorder is placed in the playback state or fast winding state while other equipment such as the tuner is in operation, the power of the other equipment such as the tuner is automatically turned off, and the tuner etc. To inexpensively and reliably perform a series of control operations in which the power source of other equipment such as the tuner is maintained as it is when a tape recorder is put into a recording state to record the contents of other equipment with a simple configuration. The main objective is to provide a tape recorder that can perform

Another object of the present invention is to control other equipment such as the tuner as described above, and to control the playback operation state and the fast winding operation state such as fast forwarding and rewinding.
To prevent the inconvenience of other equipment such as a tuner returning to an operating state due to the operation of the recording operation member by mistake, and to prevent the inconvenience that occurs even if a large operating force is applied to the recording operation member in the above case. It is an object of the present invention to provide a tape recorder which prevents malfunctions from occurring in the control of other equipment such as a tuner.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a playback rod, 2 is a fast-forward rod, and 3 is a recording rod, each of which is slidably provided in the directions of arrows A and A' by a guide member (not shown), and by a spring (not shown) in the direction of arrow A'. In other words, it is biased in the stopping direction. Reference numeral 4 denotes a locking plate, which is provided so as to be slidable by shafts 5 and 6 in the directions of arrows B and B', which are substantially perpendicular to the directions of arrows A and A'.
One end 4a thereof is engaged with a concave portion 7a of a head substrate 7 which is interlocked with the reproduction rod 1. Reference numeral 8 denotes a first control plate, which is driven by the shafts 5 and 6 to move arrows B,
It is provided so as to be slidable in the direction B', and is biased in the direction of arrow B by a spring 9. Reference numeral 10 denotes a switch operating lever, which is rotatably provided on the shaft 11 of the recording rod 3, biased counterclockwise by a spring 12, and whose first engaging portion 10a is connected to one end of the first control plate 8. 8a, and is held in the state shown in FIG. 1 in the stopped state. Reference numeral 13 designates a second control plate, which is used to operate the recording rod 3 from the stopped state shown in FIG. Just before the engagement is released (at least at the same time), the second engaging portion 10b of the switch actuating lever 10 is brought into contact with the second engaging portion 10b to prevent the switch actuating lever 10 from rotating in the counterclockwise direction. The sloped portions 8b and 8c of the first control plate 8 are adapted to engage with the shaft 1a of the regeneration rod 1 and the shaft 2a of the fast-forwarding rod 2, respectively. 14 is a control switch,
an actuating piece 15 provided opposite the switch actuating lever 10 and made of an elastic body of the lever 10;
The operator 14a is pushed and moved, and the switch 14
The switching is now taking place.

Further, the control switch 14 is connected to a power supply control means 16 of other equipment such as a tuner, as shown in FIG. 8, so as to control the power supply control means 16.

Reference numeral 17 designates a power switch for the tape recorder of this embodiment, which is linked to the first control board 8, and when the playback rod 1 and fast forward rod 2 are operated, its operator 17a is pushed and moved by the first control board 8. The power supply 19 is turned on from off to supply power 19 to the recording/reproducing amplifier 18 of the tape recorder, the tape running drive motor (not shown), and the like.

Next, the operation of the above embodiment will be explained.

When the recording rod 3 is operated in the direction of arrow A from the stopped state, which is the non-operating state of operations such as recording, playback, and fast winding shown in FIG. The shaft 1a and the inclined surface 8b of the first control plate 8 cause the first control plate 8 to slide in the direction opposite to the arrow B, ie, in the B' direction, against the force of the spring 9, and the power switch 17 is turned on. Then, tape constant speed feeding starts.

At the same time, the head board 7 is moved in the direction of arrow B, and therefore the locking plate 4 is also moved in the direction of switch B, so that the first engaging portion 10a of the switch actuating lever 10 is connected to the other end of the locking plate 4. 4b, the recording rod 3 is held in the state shown in FIG. 3, and at the same time the electric circuit system is switched to the recording position, and the tape recorder enters the recording state. The regeneration rod 1 is held in the operating position by a locking mechanism (not shown). At this time, the switch operating lever 10 is prevented from rotating counterclockwise by the spring 12 by the second control plate 13, so that the control switch 14 is in the operating state (in this embodiment, the off state) as well as the stopped state. situation)
Therefore, the power supply control means 16 for other equipment such as tuner
does not perform an operation to cut off power to the device, and other devices such as the tuner are enabled to operate, and the signal from the tuner etc. can be recorded by a tape recorder.

When the playback rod 1 is released from the operating position in the recording state shown in FIG. 3, the playback rod 1 is slid by the force of a spring (not shown) in the direction opposite to arrow A, that is, in the direction of A', and at the same time the head board 7 is also moved. arrow
The locking plate 4 is also slid in the B' direction, and the second engaging portion 10b of the switch actuating lever 10 and the second control plate 13 are in contact with each other. The first engaging portion 10a of the switch actuating lever 10 and the other end 4b of the locking plate 4 are released from the lock and returned to the stopped state shown in FIG. 1. At this time, the control switch 14 is kept in the OFF state, and other devices such as the tuner remain operable.

Next, when the regeneration rod 1 is operated in the direction of arrow A from the stopped state in FIG. 1, the locking plate 4 is slid in the direction of arrow B and the power switch 17 is turned on, and the first control plate 8 and spring 9
It is slid in the direction of arrow B' against the force shown in FIG. 4, resulting in the regenerated state shown in FIG. When the locking plate 4 is in the state shown in FIG.
c, and the recording rod 3 is prevented from being operated in the direction of arrow A.

At the same time, the control switch 14 becomes inactive (on in this embodiment), and the power supply control means 16 for other equipment such as the tuner is operated to cut off the power supply to the equipment, and the other equipment such as the tuner is operated as necessary. It is assumed to be in working condition.

Next, from the stopped state shown in FIG.
When the switch is operated in the direction of the arrow A, the first control plate 8 is slid in the direction of the arrow B' by the shaft 2a and the slope 8c against the force of the spring 9, and together with the switch actuating lever 10, the first control plate 8 is moved in the fast forward direction shown in FIG. state. When the switch operating lever 10 is in the state shown in FIG.
The first engaging portion 10a is the other end 4 of the locking plate 4.
This comes into contact with the stepped portion 4d of b and prevents the recording rod 3 from being operated in the direction of arrow A.

At the same time, the control switch 14 is brought into the inactive state and turned on, as in the previous playback state, and the power supply control means 16 for other equipment such as the tuner is operated to cut off the power supply to the other equipment, such as the tuner. is considered inactive.

Next, after operating the recording rod 3 in the direction of arrow A from the stopped state shown in FIG.
The switch operating lever 1 is slid in the direction B'.
0 is the second control plate 13 and the second engaging portion 10b
As a result, the state shown in FIG. 7 is reached, and the recording rod 3 is not locked. When the operation of the recording rod 3 is released, the state shown in FIG. 6 is achieved.

Next, from the stopped state in Figure 1, press the recording rod 3 halfway and operate the playback rod 1, and the second
As shown in the figure, the first engaging portion 10a of the switch actuating lever 10 and the other end 4b of the locking plate 4 come into contact with each other, but if the recording rod 3 is operated in the direction of arrow A from this state, the recording as shown in FIG. state, recording rod 3
If the operation is released, the playback state shown in FIG. 4 will be achieved.

Also, at this time, the switch operating lever 10 is in the first position.
Although it is further rotated clockwise from the state shown in the figure or the state shown in FIG. 3, since the actuating piece 15 is made of an elastic body, no great load is applied to the control switch 14. .

Preventing the operation of the recording rod 3 from the playback state shown in FIG. 4 and from the fast forward state shown in FIG.
0a is brought into contact with one end 4b of the locking plate 4. At this time, the switch actuating lever 10 is rotated clockwise, and when it becomes greater than the frictional holding force, the blocking is released. As shown in Fig. 5, stepped portions 4c and 4d are provided to reliably prevent the rotation. In this embodiment, one end 4 of the locking plate 4
Although step portions 4c and 4d are provided at b, these may be simply inclined portions.

The interlocking mechanism between the reproducing rod 1 and the head board 7 is well known, so detailed description thereof will be omitted.

Further, in this embodiment, only the fast forward operation was explained as the fast winding operation, but it goes without saying that the same applies to the rewinding operation.

As explained above, the tape recorder of the present invention includes a recording operation member, a switch operation member rotatably provided on the recording operation member and biased in one direction by an elastic body, and a switch operation member that is operated by the switch operation member. a switch means for controlling power supply to other devices such as a tuner in an operating state and stopping power supply in an inactive state; a playback operation member;
It is interlocked with a fast winding operation member that performs a rewinding operation, etc., and prevents rotation of the switch operating member due to the biasing force of the elastic body in the stopped state, so that even if the switch operating stage is brought into the operating state, the playback does not occur from the stopped state. a first control member that is moved out of a rotation blocking position of the switch operating member by the biasing force of the elastic body by operating an operating member or a quick winding operating member, and causes the switch means to be in a non-operating state; The recording operation member is operated from a stopped state, and the switch operation member is prevented from rotating at least at the same time when the first control member is about to release the rotation prevention of the switch operation member, and the switch means is brought into the operation state. Since a second control member is provided to hold the tuner, if a recording operation is performed while another device such as a tuner is in operation, the other device such as the tuner continues to operate as it is, and no sound is heard from the tuner. Although it is possible to record signals, if you perform playback or fast winding while another device such as a tuner is in operation, the power of the other device such as a tuner is automatically turned off, and you have to manually turn off the power of the other device such as a tuner. There is no need to turn off the power, improving operability.

In addition, if the recording operation is prevented from the playback mode or fast winding mode, it is possible to accidentally perform the recording operation when other equipment such as a tuner is turned off in the playback mode or fast winding mode. The power supply to the other devices will not be restarted as a result of this operation, and the user will not feel any discomfort.

Furthermore, if a sloped portion is provided in the operation blocking portion of the locking member that prevents the recording operation from the playback state or the fast winding state, the operation blocking state can be easily released even if the recording operation member is operated with great force. It won't happen.
