A coin-operated phonograph in which certain functions are remotely controlled. A transmitter is provided for transmitting a number of modulated carrier signals, including an up volume signal and a down volume signal. The phonograph carries a multi-channel receiver that is adapted for receiving the carrier signals transmitted by the transmitter. A detector is connected to the receiver for detecting the modulated carrier signals. An amplifier with gain control is provided and is controlled in accordance with receipt of the modulated carrier signals. A manually-operable volume control switch is carried by the phonograph and may be used instead of the transmitter to control the gain of the amplifier.

Remote-control system for coin-operated phonographs

A coin-operated phonograph is provided which includes a cathode ray tube for displaying information, such as title strip data, in alphanumeric form. The phonograph includes means for storing the information to be displayed in digital form. An optical character reader is used for entering the information into storage in the storage means. Means are responsive to the storage means for controlling the presentation of the information on the cathode ray tube.

Coin-operated phonograph

An arcade game in which the housing defines an opening on the front portion of the housing. A sliding panel which carries electronic circuitry is slid into and out of the housing, through the opening, along tracks. The front of the housing has a door for covering the opening, but this door is normally locked and can be unlocked only from inside the housing. To obtain access to unlock the door, the coin box closure on the front of the housing must be unlocked, enabling the operator to extend his hand into the interior of the housing to unlock the door.

Arcade game housing

An electronic test circuit is disclosed for pinball type games. A microprocessor is programmed to provide scoring responsive to detecting the actuation of the various switches located on the game surface. A sequencing device controls operation of the microprocessor to perform a test routine whereby the microprocessor will sequentially operate every light, ball ejector and switch position to permit testing of these devices for possible repair or replacement. The sequencing device can cause the microprocessor to continuously cycle through all of the test positions or can cause the microprocessor to single step through each test position and repeat testing of a given position as often as necessary to correct a located defect.
