    摘要： An on-vehicle electronic device includes a main body which is fastened to a vehicle and has a first terminal, and an operation unit which is detachably mounted in the main body and which has a second terminal electrically connected to the first terminal when the operation unit is mounted in the main body. The main body includes a reference power source applying a reference voltage to the first terminal, and a voltage detection unit for detecting a voltage applied to the first terminal. The main body further includes a mounting detection unit. The mounting detection unit determines, based on a difference between a first detection voltage detected by the voltage detection unit when the operation unit is mounted and a second detection voltage detected by the voltage detection unit when the operation unit is not mounted, whether or not the operation unit is mounted and electrically connected to the main body via the first and second terminals.

    摘要： An audio apparatus having a detachable control panel or operating-part main unit includes a microcomputer for detecting an OFF state of an ACC position of the ignition key, or the attached/detached state of the operating-part main unit. When such states are detected, normal operations of the microcomputer; namely, the operations to turn on an SWD V.sub.DD terminal and an A/D port and to set a KEY DATA terminal into a standby mode, are stopped intermittently in order to execute a low consumption process in which electric power is consumed only for holding information in memory in the microcomputer. When the microcomputer detects the OFF state of the ignition key or the OFF state of an installation detection switch and, an alarm ON state is set in the memory in the microcomputer, then an alarm sound is generated from a speaker for a predetermined time. When the alarm sound is unnecessary, the state of the memory in the microcomputer can be updated to an alarm OFF state by depressing a function button and operating the ignition key. When the installation detection section detects the removal of the operating-part main unit, on the basis of a decrease in voltage value of an installation detection switch section and CPU recognizing the removal of the operation-part main unit, a control section sends control signals to a power supply limiting circuit and a data transmission switch section.

    摘要： The information recording unit has a memory for firstly storing data, a record medium for intermittently recording the stored data in the memory, a record means for recording the data on the record medium, and a valid-data decision means for determining whether the recorded data is valid. The record means records the data in at least two different areas on the record medium, and the decision determines one valid data among the recorded data in the different areas. The unit includes a record control means for controlling the record means. The record control means provides a control command for the record means to record a predetermined quantity of data stored in the memory at a first recording location on the record medium and also provides a control command for the record means to read the predetermined quantity of the data at least one recording location different from the first recording location after the predetermined quantity of the data is recorded at the first recording location.

    摘要： An information reproduction unit has a data read means with a pickup for intermittently reading data recorded on a storage medium, a write means for writing the data in a memory, and a reproduction means for sequentially reading out the data written in the memory. The unit also has a defect detection means for detecting a defect of the storage medium during a data read waiting period. The defect detection means may determine the presence of a defect based on a readout result provided by the data read means. The unit may further include a storage means for storing a defect position information. Furthermore, a read characteristic may be adjusted on reading data at the defect position on the storage medium.
