An information processing apparatus (S) of an on-vehicle type is provided with a fan ( ) and a detecting device ( ) for detecting an operation status of a vehicle. The information processing apparatus is also provided with a controlling device ( ), for controlling a rotation speed of the fan in accordance with the detected operation status.

A system for moving a television set has a carrier slidably mounted in a casing. The television set is pivotally mounted in the carrier at a front portion of the carrier. A carrier driving motor and a television set rotating motor are provided. A memory is provided for storing positions of the carrier and an angular position of the television set. A control unit is provided for controlling the carrier driving motor and the television set rotating motor in accordance with the positions stored in the memory for moving the carrier between a forward position and a backward position in the casing and for rotating the television set between a downward position and a standing position. Thus the television set is moved between a retracted position in the casing and the standing position outside the casing.

A car stereo has a detachable grille attached to a body of the car stereo. A display is provided on the car stereo body for display operating modes of the car stereo. A cover is provided on the car stereo body for covering the display when the grille is detached. The cover is moved to a retracted position so as to expose the display when the grille is attached to the body.

Car stereo having a detachable grille

A grille of a car stereo has a recess, an operation flap pivotally mounted in the recess, an opening for inserting a sound recording medium formed at a position behind the flap, and a liquid crystal display panel provided in the flap. The lighting device has a light source provided behind the grille and a light introducing plate, so that the liquid crystal display panel and the opening are lighted by light transmitted from the light source through the light introducing plate.

A burglarproof device includes an accessory switch detection circuit for detecting ON/OFF states of an accessory switch provided in a vehicle. An accessory switch detection signal is sent to an alarm generation circuit. The alarm generation circuit generates an alarm signal when the accessory switch is in an OFF state. This alarm signal alarms that a detachable electronic equipment adapted to be mounted in vehicles which has been mounted in a vehicle is actually attached to the vehicle. This alarm informs a driver that he forgets detachment of the electronic equipment adapted to be mounted in vehicles, thus preventing burglarly.

A cassette tape loading and ejecting mechanism in a tape player for playing back tapes using a driving force of a main motor. The mechanism includes a sun gear provided in part of a mechanism for transmitting the driving force of the main motor. A stationary ring gear is arranged coaxially with the sun gear. A carrier is mounted on a shaft coaxially with the sun gear and is engaged by friction with the sun gear. A planet gear supported by the carrier engages the sun gear and the ring gear. A slot-in type tape cassette holder is driven by the forward and reverse rotation of the carrier for loading and ejecting tape cassettes. The planet gear engages the ring gear when the main gear when the main motor rotates forwardly and the carrier is caused to turn forwardly whereby the planet gear is positioned opposite to an untoothed portion of the ring gear after a tape cassette is loaded and the carrier then stops to allow the playback of the tape continuously. The planet gear again engages the ring gear when the main motor rotates reversely and the carrier turns reversely to cause the tape cassette to be ejected.

In a head rotation mechanism in an auto-reverse type tape player, the head rotation mechanism comprising a sector gear engaging with a cam gear provided on a head lead side of a rotary head; a boss extending in the direction opposite to the rotary head side of the sector gear and having a tapered foreend; and a link mechanism for rotating the head. The link mechanism is rocked by the cam gear and equipped with a U-shaped member engaging with the boss on the sector gear. The boss on the sector gear engages with the U-shaped member of the link mechanism for rotating the head only when the rotary head is located at a release position, and the boss is out of contact with the U-shaped member when the rotary head is located ahead of the release position, whereby a reversible rotation of the single cam gear is used to change a direction of the rotary head and move the head forward.
