摘要： PURPOSE:To improve remarkably the operability by obtaining desired function through a single operation and executing the changeover from any of at least two functions into other function through the single operation. CONSTITUTION:When a cassette half is loaded to a tape deck 7 at first, a loading detection switch 21 supplies the 1st operation command signal to a tape power supply 24, a power voltage is fed to the tape deck 7 to attain tape reproducing state. In operating an eject key, an eject detection tuner 22 applies the 1st stop command signal to a tape power supply 24 to stop the tape deck 7. In operating the tuner switch 23 next, a power upply command is fed to the tuner power supply 25, an FM tuner section 9 becomes in the FM broadcast reception state. In operating the AM switch 4 to the FM broadcast reception state, an AM reception command signal is fed to the tuner power supply 25 from a control circuit 10 to stop the supply of the power voltage to the FM tuner 9 and the power is fed to the AM tuner 8 to attain the AM broadcast reception state.
摘要翻译：目的：通过单次操作获得所需功能，并通过单次操作执行从至少两个功能中的任何一个切换到其他功能，从而显着提高可操作性。构成：首先将盒半体装载到磁带架7时，装载检测开关21将第一操作命令信号提供给带式电源24，将电源电压馈送到磁带卡座7以获得磁带重放状态。在操作弹出键时，弹出检测调谐器22将第一停止命令信号施加到磁带电源24以停止磁带卡座7.接下来，在操作调谐器开关23时，向调谐器电源25馈送电力供应命令 FM调谐部9成为FM广播接收状态。在将AM开关4操作到FM广播接收状态时，AM接收命令信号从控制电路10馈送到调谐器电源25，以停止向FM调谐器9提供电源电压，并且将电力馈送到 AM调谐器8，以实现AM广播接收状态。

摘要： A motor vehicle broadcast receiver is specified which contains: a first memory for recording received field strength information in accordance with the received field strength determined from a broadcast transmitter currently received when a traffic announcement/programme identification detector circuit outputs a PI signal which identifies a broadcast station sending out traffic programmes or a TA signal which identifies the current sending-out of a traffic announcement; and a second memory for recording received frequency information at the time at which the first memory records the received field strength information. The first and second memory are set up in such a manner that the received field strength information which is recorded in the first memory is compared with a subsequently determined received field strength information in order to overwrite the content of the first memory with the new received field strength information when the latter represents a higher field strength level than the received field strength information previously stored in the first memory. At the same time as the content of the first memory is overwritten, the frequency information contained in the second memory is overwritten with the new frequency information allocated to the higher received field strength so that the broadcast receiver is automatically set to a traffic programme transmitter which generates the highest received field strength at the location of reception.

摘要： PURPOSE:To make a user recognize the cause of being unable to lock in by completing the ejection of a disk in disregard of a reloading command by the user during the ejection of the disk in the case that focusing of the disk is not effected. CONSTITUTION:A command to commence a focusing action is generated to a focusing servo circuit 28 by CPU 20, and simultaneously a timer built in CPU 20 is started. Then, it is discriminated whether the focusing servo is locked in or not, and the timer is cleared in the case that the servo is locked in. In the case where the servo is judged as not being locked in, it is discriminated whether a fixed time has elapsed or not; and if it has elapsed, a command for ejection is generated to a loading motor 7 through a motor driving circuit 30. In other words, a disk is ejected after a fixed time is elapsed in the case that focusing is not effected for such reason as the disk is inserted upside down.

摘要： PURPOSE:To always attain the restriction of continuous focusing operation by detecting no output of a lock-in signal also after the passage of prescribed time and clearing the contents of a detecting signal counting counter to be transferred to a stop mode in accordance with a disk inject or stop command. CONSTITUTION:When an optical pickup 14 is defocused, focusing operation for feedback control is started through a focus servo circuit 28 or the like and a lock-in signal is supplied from a circuit 29 to a CPU 20 in accordance with leading-in of focus servo. When the CPU 20 detects no generation of the lock-in signal within a prescribed time, a counter built in the CPU 20 counts up the detection signals, and when the count value reaches a prescribed value, the CPU 20 transfers the operation to the stop mode. If a disk inject or stop command is applied through an operation key group 5, the CPU 20 clears the contents of the built-in counter and prepares the succeeding operation processing. Consequently, continuous focusing operation more than the prescribed number of times is always restricted and the pickup is prevented from heating or the like through the focusing actuator.

摘要： PURPOSE:To simplify the control of replaying of an ejected disk by invalidating the contents stored in a recording information storing means in a read-in area of a disk at the disappearance of a slot position detecting signal after the completion of carrying of the disk by a loading mechanism. CONSTITUTION:In the read-in area of the disk 3, TOC information such as the number of musical programs recorded on the disk, the total absolute time and the playing time of each musical programs is recorded, and the read TOC information is stored in a RAM21. When the ejecting operation of the disk 3 is completed after the end of playing, a CPU20 detects the completion and then decides the existence of a load command. When the disk 3 is ejected at the decision of absence of the load command, the TOC information stored in the RAM21 is invalidated at the decision of ejection of the disk from a slot position. Thus, the replaying of the ejected disk can be simply controlled.

摘要： PURPOSE:To suppress the continuous supply of starting current to a focus actuator by counting up the number of times of no generation of a lock-in signal within a prescribed time and transferring operation to a stop mode. CONSTITUTION:An optically read reproduced signal of information on a disk 3 by a pickup 14 is supplied to a CPU 20 through a signal processing circuit 25 or the like, and at the time of out-of-focusing, focusing operation of the pickup 14 is started through a focus servo circuit 28 and a lock-in signal is supplied at the leading-in of the focus servo. If the lock-in signal is not supplied after the passage of prescribed time from the start of focus servo, the CPU 20 detects the status and allows a built-in counter to count up the number of times of detection. When the count value of the counter reaches a prescribed value, the CPU 20 specifies a stop mode. In an on vehicle disk player which may easily generate defocusing, the number of times of focusing operation is restricted, the continuous supply of starting current to the focus actuator is suppressed and the pickup is prevented from heat generation.
