And a medium discharge system for starting a drive motor to discharge the recording medium out of the unit body, regardless of whether the power supply of the recording apparatus is on or off. , A unit power control system for operating each of the medium detection means, the medium display system, and the medium discharge system.

In this case, the unit power supply control system includes a power supply battery which is constantly charged from a charging terminal,
The medium detection means, the medium display system, and the medium discharge system are operated by an operation signal output from a power supply control circuit connected to the power supply battery.

Further, the medium detecting means can be constituted by a light emitting element such as a light emitting diode and a light receiving element.

Further, the medium display system includes a medium display circuit which operates in response to an operation signal from a power supply control circuit.

Further, the medium discharge system may include a drive motor started by an operation signal from a power supply control circuit and a medium discharge mechanism operated by the drive motor.

Therefore, according to the above configuration, when a recording medium such as a disk is mounted inside the unit main body, the medium detecting means detects the disk and sends a detection signal to the medium display system. The medium display circuit here sends an operation signal to the medium display section to operate the medium display section, and displays on the display window that the disc is mounted.

Here, the operation of the medium display circuit can be continued even if the main power supply of the recording apparatus is turned off. The reason is that it operates by a power supply control circuit which is always supplied with power using a battery as a power supply.

Similarly, even when the power supply of the main body of the recording apparatus is turned off, the disk can be ejected from the unit main body and taken out. That is, when the medium discharge switch is turned on, the drive motor is started via the power supply control circuit, and the medium discharge mechanism can be operated to take out the disk.
