When the drive switch 15 is turned on, the external remote control terminal 6 The motor 14 can be driven or stopped by a control circuit connected to the external remote control connection terminal 4 connected to the external remote control connection terminal 4 . On the personal computer 1 side, this control is performed by opening and closing a relay 16. When nothing is connected to the external remote control terminal 6, the internal switches 6a and 6b of the external remote control terminal 6 are connected, and the motor 14 is driven or stopped only by opening and closing the drive switch 15.

When attempting to examine the contents of recorded data in a program recorder configured as described above, a human being cannot understand the data even if it is monitored through a speaker, and the data must be input into a personal computer. For this reason, it is common practice to record the contents as audio just before recording the data. Also, add audio between programs,
It is also common to use it for instructions or explanations.

However, with conventional program recorders,
If you connect it to a personal computer and try to record audio while recording data, it is necessary to disconnect the external signal input connection terminal 3 and the external remote control connection terminal 4 each time, which is very complicated and necessary. This has the problem that sounds other than the above are likely to enter.

Purpose of the invention This invention solves the above-mentioned conventional problems. Even when a personal computer and a program recorder are connected, it is possible to easily record desired audio by pressing a switch provided on the program recorder side. Its purpose is to provide a program recorder.

Structure of the invention This invention is a program recorder equipped with a circuit and a switch for recording audio, making it possible to easily input data contents, instructions, or explanations by audio before and after data recording. Become.
