Title: Preview mechanism provided with automatic film rewinding function
Inventor: KAKIUCHI TOSHIHIRO
IPC: G03B9/07
Filed: 1990-05-14
Abstract: PURPOSE:To efficiently use a motor built in a camera by stopping down a stop-down structure by utilizing the one-way rotation of the motor and using the reverse rotation of the motor for a rewinding driving source.

Abstract: PURPOSE:To make wider the dynamic range, to make equal the leading and trailing slope time, and to reduce the variation in the slope time variation due to temperature, by providing the switching circuit for the constant current circuit flowing the discharge current of capacitor. CONSTITUTION:The input signal (a) is fed from the input terminal, and the constant current circuit flowing the discharge current of the capacitor C2 (consisting of transistors TrT13-T15) is switched with the switching TrT16. Since the constitution like this is taken, the collector currents I5, I7 and I8 of TrT13-T15 are almost equal, and the charging current I6 (collector current of TrT12) of the capacitor C2 is equal to the collector current I5 of TrT11 with the constant current circuit constitution of TrT10-T12, the discharge current of the capacitor C2 I9 is nearly equal to I6. Accordingly, the saw tooth wave (b) in which the leading slope time T'3 by current I6 is equal to the trailing slope time T'4 by current I9, can be obtained. Further, since the low level of the saw tooth output is lowered to the level of VCFsat voltage (nearly equal to zero) of TrT14, T15, the dynamic range (difference between the low and high level of saw tooth wave) can be taken broader.

Abstract: PURPOSE:To eliminate the necessity of converting the time differential against a communicating partner by discriminating the nation code of the communicating partner in the registered telephone number of the partner and sending the facsimile message after changing the transmitting time in the transmitting source information to the time of the nation of the communicating partner. CONSTITUTION:A control circuit section 8 takes the sum of the already inputted time differencial between its own equipment and the equipment of a communicating partner and the current time of its own equipment so as to calculate the current time of the nation where the partner equipment is installed and outputs the calculated current time of the partner equipment to a transmitting source information preparing section 4 as an information signal (c) indicating the time of the nation of the communicating partner. At the moment when a communicating procedure protocol is completed before sending picture signals, the control circuit section 8 outputs a transmitting source information output instructing signal (m) to the transmitting source information preparing section 4 and the section 4 outputs the transmitting source information to a coding circuit 3 as transmitting source information outputting signals (b). The signals (b) are coded by means of the coding circuit 3 and sent to the partner equipment through a MODEM 2 and line control circuit 1. Therefore, the problem of converting the transmitting time in the transmitting source information can be eliminated.
