This is fa Figure 3-1, Figure 3-2 70-cha) K
explain about.

First, when the button operation switch 491L is turned on and a control input command is input to the control means M and the control means B, the radio mode and mechanism mode are in the stopped state (step 2) when the button operation switch 491L is turned on (step 1). .3)
If the button operation switch 491L is ON for less than 0.6 seconds, go to playback (step 4.6);
If it is longer than 6 seconds, an operation command is output so that the state of the radio mode and mechanism mode changes to radio activation (step 4.6). If the mechanism is in the regeneration state (step 7) and the button operation switch 49& is ON for more than 0.6 seconds, go to inversion (step 8゜9).
If it is the first time in less than 0.6 seconds, stop (steps a, 1o
, 11), or fast forward (step 12.1) for the second time.
Go to step 3) and rewind for the third time (step 14.1g)
A mechanism operation command is issued so that the mechanism changes state.

When the mechanism is neither in the stop state nor in the regeneration state (steps 3 and 7), a mechanism operation command is output to bring the mechanism into the regeneration state (step 6) regardless of how long the button operation switch 491L is pressed.

While the radio is operating (step 2), if the button operation switch 491L is on for more than 0.6 seconds, it will stop (step 17.18), and if it is less than 0.6 seconds, it will turn on.
For the second time, change the memory (ST, PU 1y, 1s, 2o)
), and for the second time, switch the band (step 21, 2).
2) Outputs radio operation commands to

Here, steps 2 to 18 are the states and operation commands of 300 control means B, and steps 19 to 23 are the states and operation commands of 32 control means B.

As described above, the step of determining the state of the radio mode and mechanism mode when one button operation switch 49 & is turned on, the pulse width which is the ON time of the one button operation switch 491L, and the pulse number which is the number of ON times are determined. Combining the steps of detection and discrimination, playback 2 reversal, fast forward 1
Rewind, stop.

By outputting operation commands for radio 0N10FF, memory switching, and band switching in accordance with the detected pulse width and number of pulses, the radio mode and mechanism mode can be switched to the next state with a single operation switch. can.

Further, when the mechanism is in the operating state, the control means B of a2 does not perform any operation related to the radio operation, but the output 30h of the control means B of 30 sends a signal corresponding to the operating state of the mechanism to the control means 32. By sending it to input 321 of B,
The operating state of the mechanism can be output more than 32h and displayed on the display unit 36. The output aoh of the control means 3o outputs a signal that displays the operating state of the mechanism on the display unit 35 only when the operation of the mechanism is confirmed.
6 outputs a signal that does not appear.

In addition, although the embodiment describes a tape recorder with a radio, the present invention can also be applied to other audio devices.

Further, in the embodiment, two control means are used, but it is also possible to use one control means.

Effects of the Invention As described above, the present invention includes a control means for executing operation control in mechanism mode and operation control in radio mode, and 1 for generating preset pulse signals to issue a plurality of operation commands of the control means. The control means is provided with a pulse signal detection means and a control means for issuing operation commands, and the mechanism mode and radio mode are controlled, so that multiple operations can be performed with a single operation switch. becomes possible.

Furthermore, by dividing the control means for controlling the mechanism operation and the radio operation control into two, it becomes possible to implement the control means using different power supply voltages.

Furthermore, a control means K executes operation control of the radio.

(by inputting a signal corresponding to the operating state of the mechanism from a control means that controls the operation of the mechanism),
The operating status of radio mode and mechanism mode can be displayed.
