PURPOSE:To reduce the amplification of transmission signals relating to a single element tape reception circuit for which a light emitting element is used as a light receiving element. CONSTITUTION:In this single element type reception circuit, a preamplifier output fixing circuit 4 is provided between a preamplifier 3 and an amplifier 5. By providing the preamplifier output fixing circuit 4 between the preamplifier 3 and the amplifier 5, at the time of driving a transmission circuit, the amplification of the transmission signals current-voltage converted by the preamplifier can be reduced. |
