Title: Image communication device
Inventor: KUKIHIRA HIROO
IPC: H04M11/00
Filed: 1991-08-12
Abstract: PURPOSE:To easily and securely switch a line to a facsimile side by generating a prediction tone and switching the line in response to on-hook operation when a facsimile signal is received from an opposite party while a telephone set is in the off-hook state. CONSTITUTION:The contact of a CML relay 8 is connected normally to the telephone set side. When facsimile transmitting operation from the opposite party is performed in this state, a hook detecting circuit 1 detects the off-hook state and sends its output to a control circuit 7. An identification signal detecting circuit 3, on the other hand, sends variation of the facsimile identification signal to the circuit 7 when detecting the facsimile identification signal. The circuit 7 recognizes the variation of the outputs of the circuits 1 and 3 and puts a prediction tone generating circuit 4 in operation. After the prediction tone, the circuit 7 switches the contact of the relay 8 to the facsimile side a constant time later. Consequently, the line can easily and securely be switched to the facsimile side without requiring any hooking operation.

Title: Bimorph shutter
Inventor: TANAKA YOSHIHIRO
IPC: G03B9/10
Filed: 1988-09-09
Abstract: PURPOSE:To always attain a correct exposure operation by correcting an exposure control value derived from the object luminance and the film sensitivity with the corrected amount based on the detected temperature and controlling an energization to a bimorph element. CONSTITUTION:The bimorph Bi to be a shutter driving force is equivalently a sort of capacitor, increases in volume as temperature rises, and decreases in volume as temperature falls. Therefore, when the microcomputer muC reads a photometric value Bv from a photometric circuit Bv and carries out an exposure arithmetic operation using the film sensitivity and photometric value Bv derived from a film sensitivity reading circuit DX, the temperature dependency of the exposure amount is corrected. For this purpose, a temperature detecting circuit TEMP is provided near the bimorph to detect the surrounding temperature and this data is outputted to the microcomputer muC. Thus, by feeding back the temperature characteristic of the bimorph Bi to the exposure control and by compensating the temperature, the appropriate exposure movement is always attained.
