摘要： A recording medium reproducing device comprises: reading means using a pickup to read data from a recording medium, and outputting the data thus read; memory control means for controlling the output data of the reading means to store the data in a memory; reproducing means for reading data from the memory and converting the data into a reproducing signal; and a microcomputer for controlling the reproducing means. In the reproducing device, the microcomputer varies a threshold value set for the memory, according to the time of absence or the frequency of absence of the output data of the reading means. Thus, the reproducing device eliminates the difficulty that the user feels unpleasant because of the frequent pause of sound reproduction.

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.
