<p>PURPOSE:To dispense with a special examination machine at the time of shipment examination by providing a pulse measuring test mode for detecting a change of external light for turning a pulse detection pattern ON and OFF at a predetermined cycle and displaying the turning ON/OFF number of times per min other than a usual pulse measuring mode. CONSTITUTION:A liquid crystal panel 2 is provided with a pulse detection pattern 2c other than a time display part 2a and a calendar display part 2b and a photoreflector 3 being an optical pulse sensor is arranged to the under surface of the pulse detection pattern 2c. When a pulse measuring function mode is selected by the operation of a switch button 4, the photoreflector 3 arranged to the under surface of the pulse detection pattern 2c detects the turning ON/OFF number of times being a cycle of a change of the external light due to the turning ON/OFF of the pulse detection pattern 2c and displays the turning ON/OFF number of times per a min, that is, performs the same display as pulse measurement. By repeating the turning ON/OFF of the pulse detection pattern 2c at a definite cycle, pulse function is examined on the basis on whether a predetermined number of pulses are displayed. Therefore, the examination number of times are reduced.</p> |
