Abstract

PURPOSE:To easily check a sensor and light source, by scanning a photosensor matrix except when reading a card, and confirming its function. CONSTITUTION:This card reader is provided with an OR circuit 13 for inputting low output singnals R0-R9 obtained by column signals CLA-CLE, and an AND circuit for inputting an output of this OR circuit 13 and a signsl CHECK from the outside, and nakes the CHECK an ''H'' level at the time when a card is not read, and executes the check by continuously generating the column signal. According to this constitution, if a part of a sensor matrix 5 becomes faulty or a lamp been disconnected, it is detected immediately, and maintenance of the device is executed easily.
