Information reproducing system with improved response to intermittent power supply
First Claim
1. An information reproducing system for use in an automobile including a battery for generating a predetermined voltage level for supplying power to said system, comprising:
- a voltage detector circuit for detecting a predetermined drop in the voltage level of said battery and for detecting the predetermined voltage level, operating means for receiving the power supplied from said battery and reproducing information from that which has been stored on a recording medium, and control means for controlling the reproduction of the information by said operating means in response to an operation command input, and means for inhibiting said control means from responding to the operation command input when said voltage detector circuit has detected at least the predetermined drop in the voltage level of said battery until said voltage detector circuit detects the predetermined voltage level.

Abstract
An information reproducing system, such as an audio tape player, for automotive use, whereby errors which would otherwise occur when the engine is started are inhibited. The information reproducing system of the invention includes a voltage detector circuit for detecting the voltage of the automobile'"'"'s battery, an operating unit for operating the recording medium in response to the supply of power from the battery so as to reproduce information stored on the recording medium, and a control unit for controlling the operating unit. In this system, the application of an operation command input to the control unit is inhibited when the voltage detector circuit detects a drop in the voltage of the battery at the time the engine is started. In addition, the inhibition of the operation command input is cancelled when the restoration of the voltage of the battery is detected.
