Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape recorder with a clock configured to control the operation of a tape recorder section using a control signal from a clock section and to use a playback signal from the tape recorder section as an alarm signal. Its purpose is to eliminate the complexity of the snooze operation of the clock section, and to enable the tape recorder section to exhibit a good pause state during the snooze operation of the clock section. There is a particular thing.

Generally, when a tape recorder with a clock is used as an alarm, a control signal is output for a predetermined time at a preset time, and at any time during the output period of the control signal, a snooze switch is used to output the control signal. a clock portion configured to temporarily stop the operation for a predetermined period of time;
The regeneration state caused by the regeneration button is temporarily canceled by the pause button, that is, the power supply to the motor is temporarily stopped by the pause button, and the contact state of the pinch roller against the capstan is temporarily stopped. A tape recorder section capable of displaying a pause state to be released is combined, and when there is a control signal from the clock section, the pause state of the playback state by the pause button of the tape recorder section is canceled and the above-mentioned When the tape recorder section is returned to the playback state by the playback button, and the snooze switch of the clock section is operated in the playback state, the tape recorder section is restarted by the temporary stop of the control signal from the clock section. The tape recorder section is configured to temporarily stop the playback state and return the tape recorder section to the playback state again after a predetermined period of time has elapsed due to the snooze operation. However, in the above-mentioned tape recorder with a clock, the snooze switch of the clock section temporarily stops the control signal of the clock section, so during the snooze operation, the playback state of the tape recorder section is changed by the control signal. Even if the motor is temporarily stopped, it only temporarily stops the power supply to the motor. Therefore, in this snooze operation, the pinch roller is temporarily stopped while being pressed against the capstan, which is not preferable in terms of maintaining the function of the tape recorder section. In other words, although the pinch roller and the capstan are pressed against each other during a short pause due to the snooze operation, if this snooze operation is repeated, the pinch roller may eventually become deformed, which may impede tape running. There was a problem with adding. In order to avoid this problem of deformation of the pinch roller, the pressure contact state of the pinch roller against the capstan during the snooze operation is released again by operating the pause button, and the tape recorder section is completely paused. However, in this case, you have to perform two operations: operating the snooze switch on the clock section and operating the pause button on the tape recorder section, making the operation for snoozing operation complicated. There were flaws.

The present invention eliminates such conventional drawbacks, and the present invention will be described below with reference to drawings of embodiments.

FIGS. 1, 2, and 3 show an embodiment of a tape recorder with a clock according to the present invention. In the figures, A is a clock section, and B is a tape recorder section. Above clock part A
is equipped with a clock LSI 1, a time display 5, a clock power source 3, and a snooze switch S ₁ , and a control signal is output from the output terminal 4 for a predetermined time at a preset time, and the control Snooze switch at any time during the signal output period
When _S1 is operated, the control signal from the output terminal 4 is temporarily stopped for a predetermined period of time. It goes without saying that the output period of the control signal is set to a time width that is sufficiently larger than the pause period of the snooze switch _S1 . The tape recorder section B includes a reproduction amplification circuit 5, a plunger 6, a motor 7, a power switch _S2 , transistors _TR1 to _TR4 , and resistors _R1 to
_R4 , a capacitor C, and a diode D, and is configured such that the tape playback state by a playback button (not shown) can be temporarily canceled by pressing the pause mechanism 8. That is, in the regeneration state, the power switch _S2 is closed to supply power to the motor 7, and a pinch roller (not shown) and a capstan (not shown) are pressed together,
A magnetic head is brought into contact with the tape in a tape cassette (not shown), and playback is performed at a predetermined tape running speed. However, in the paused state, the power switch _S2 and the magnetic head remain as they are, and the pinch roller is turned off. This releases the press-contact state of the capstan and temporarily stops the power supply to the motor 7. Here, the temporary stop mechanism 8 is attached to the tip of a temporary stop lever 9, as shown in FIGS. 2 and 3, and the temporary stop lever 9 is equipped with a lock pin 10, and is attached to the first mounting board 11 so as to be slidable. The lock pin 10 of the temporary stop lever 9 protrudes from the relief hole 12 of the first mounting board 11 and faces the locking pawl 15 of the lock lever 14 supported by a shaft 13 provided on the first mounting board 11. are doing. The lock lever 14 has one end of a coil spring 16 attached to the shaft 13 hooked on a protrusion 17 of the lock lever 14, and the other end hooked on a protrusion 18 provided on the first mounting board 11. As a result, it is biased clockwise in FIG. 2, and is supported on a shaft so that it can rotate counterclockwise in FIG. A lock release lever 19 having an escape hole 22 for the lock pin 10 is provided on the lower surface of the lock lever 14. This lock release lever 19 has a protrusion 21 inserted into the through hole 20 of the first mounting board 11. It is supported so that it can swing freely. At the other end of the lock release lever 19, there is provided a second mounting plate located opposite to the first mounting board 11.
A plunger 6 fixed to a mounting board 23 is connected. This plunger 6 is the rod 2
4 is urged by a spring 25 in the direction of arrow X in FIG. It is connected to the lock release lever 19. Further, a snooze switch _S1 is disposed on the first mounting board 11 within the rotation locus of the lock lever 14 so as to be closed when the lock lever 14 rotates clockwise.

In a tape recorder with a clock configured as described above, the playback button is pressed to enter the playback state, the pause button is pressed to temporarily stop the playback state, and the fourth
As shown in FIG.
5, and the tape recorder section B is maintained in a paused reproduction state. On the other hand, the clock section A is set so that the control signal is output at a desired time. In this state, when the time preset by the clock section A arrives, a control signal is output from the clock section A to the output terminal 4 to turn on the transistor TR ₁ , which causes the transistors TR ₂ and TR ₄ to be turned on.
is turned on, power is supplied to the motor 7 and the regenerative amplification circuit 5, and they begin to operate. On the other hand, when the transistor TR ₁ is turned on by the control signal, the transistors TR ₂ and TR ₄ are turned on for a time determined by the capacitor C and the resistor R ₃ .
TR ₃ is turned on, power is supplied to the plunger 6, and the plunger 6 is operated. When the plunger 6 is operated, the rod 24 is pulled in the direction opposite to the arrow X shown in the figure against the biasing force of the spring 25, so that the lock release lever 1 connected to the plunger 6 is pulled.
9 rotates counterclockwise in FIG. 3 about the projection 21, and the lock lever 14 is rotated counterclockwise in FIG. 3 by the lock release lever 19. Therefore, the locked state of the lock pin 10 provided on the temporary stop lever 9 by the locking pawl 15 of the lock lever 14 is released as shown in FIG. 4a. At this time, it is no longer possible to maintain the temporarily released state of pressure contact between the pinch roller and the capstan, so the tape is returned to the playback state, and the playback signal is used as an alarm signal.

If you want to temporarily stop the alarm sound that uses the playback signal as a wake-up signal in this playback state, press the pause button on the tape recorder section B again and release the lock pin 10 provided on the pause lever 9. It is sufficient to engage the locking pawl 15 of the lock lever 14.
In the process of pressing the pause button, the lock lever 14 rotates counterclockwise against the biasing force of the coil spring 16, as shown in FIG _. Since it turns on instantly, the control signal is temporarily not output to the output terminal 4 of the clock section A. Therefore, during this snooze operation, the transistor
TR ₁ is turned off, transistors TR ₂ and TR ₄ are turned off, and at the same time, the power to the motor 7 and the regeneration amplification circuit 5 is temporarily cut off, and at the same time, the pressure contact state between the pinch roller and the capstan is released, and the regeneration state is temporarily restored. Stop at. Then, at the end of the snooze operation, the control signal appears again and the transistor _TR1 is turned on, so that the playback state returns to the same as described above and an alarm sound is generated using the playback signal as a wake-up signal.

In the above embodiment, in order to interlock the snooze switch _S1 of the clock section A with the pause mechanism 8 of the tape recorder section B, the snooze switch S1 of the clock section A is linked to the rotational movement of the lock lever 14 that constitutes the pause mechanism 8.
In addition to this, if the temporary stop lever 9 is given a stroke exceeding the lock position, the temporary stop lever 9 can be associated with a snooze switch _S1 .

As described above, according to the present invention, the snooze switch of the clock section is associated with the pause mechanism of the tape recorder section, so even when the clock section is to be snoozed, it can be performed using the same operation as for pausing the tape recorder section. This eliminates the complexity of the operation, and also prevents the deformation of the pinch roller that tends to occur when the pinch roller and capstan are released from the pressure contact state during the snooze operation and the snooze operation is repeated. It is possible to maintain good tape playback.
