Title: Fingerprint input device
Inventor: GOTOU YUKARI
IPC: A61B5/117
Filed: 1988-12-19
Abstract: PURPOSE:To provide fingerprint input with less noise due to light interference by furnishing a film having light control function, which allows passing of only the light incoming at a certain angle on at least one of the light, which is incoming to the incident surface of a prism, and the lighttaken out of the takeout surface. CONSTITUTION:A beam of light 6 cast down from a light source 2 passes through a vertical beam penetrative highpolymer film 22, and only the beam 16 consisting of component vertical to the cast-down surface 20 of a prism reaches the reflex surface 14 of the prism. The all-reflex conditions are met in a recess 13 of the fingerprint to generate an all-reflex light 17. The light incoming to a protrusion 12 of the fingerprint, on the other hand, misses complete all-reflex-conditions to cause drop of the reflexion ratio, and the light incoming to a water layer 15 also reflects in different directions to become a beam 18 with light quantity and reaches the above-mentioned vertical beam penetrative highpolymer film 22. This light 18 with the direction disturbed will further weaken after passing through the highpolymer film 22, and the light intensity of an all-reflex light can be sensed by a reflex light sensing part without generating interference.

Title: Electronic device
Inventor: HIRAMOTO MASATO
IPC: G06F12/16
Filed: 1989-12-11
Abstract: PURPOSE:To eliminate the wasteful power consumption of a backup battery and to prevent backup time from being shortened by detaching a voltage detection circuit from the backup battery at a time excepting a time when the voltage of the backup battery is supervised. CONSTITUTION:When the output port OUT of LSI 1 is switched to a high level and the circuit of an analog switch 9 is closed before the execution of a program which the voltage of the backup battery 4 supervises, a current from the backup battery 4 flows into the voltage detection circuit 5 and the voltage detection circuit 5 detects the voltage of the backup battery 4. When the supervisory program terminates execution, the output port OUT of LSI 1 returns to a low level and the circuit of the analog switch 9 is opened. Thus, backup time is prevented from being shortened since the backup battery does not come to consume wasteful power at a time excepting the supervisory time of the voltage.
