Title: Current mirror circuit
Inventor: AOKI HIDEHIKO
IPC: G05F3/26
Filed: 1985-09-30
Abstract: PURPOSE:To set the input voltage at an optional level with no limitation given to the range of application with a current mirror circuit, by using the 3rd transistor having the different polarity from the 1st and 2nd transistors and plural resistances in addition to said 1st and 2nd transistors. CONSTITUTION:The 1st-3rd transistors TrQ11-Q13 are provided and the TrQ13 has the polarity different from other two TrQ11 and Q12. The base of the TrQ13 is connected to the collector of the TrQ11. The emitter of the TrQ13 is connected to a power supply VCC via the 1st constant current source I10 and also to the bases of both TrQ11 and Q12 in common with each other via the 1st resistance R12. While the collector of the TrQ13 is grounded. Thus the currents flowing to both resistances R12 and R11 are equal to each other as long as the base currents of both TrQ11 and Q12 are disregarded. Then the current obtained by subtracting the current flowing to the R12 from the current supplied to the source I10 flows to the emitter of the TrQ13. Thus the input voltage can be set at an optional level by changing the resistance ratio R12/R11. Then the limita tion can be avoided for the range of application with a current mirror circuit.

CONSTITUTION:When a feed roller 116 at the lower side is driven, if current- energization to a solenoid 74 is stopped, the tip end side of a clutch selector arm 72 operates the side of a clutch member 10, moving a clutch selector member 30 to the side of the member 10. Therefore, toothed parts 30a and 10a are engaged with each other, and rotational force of a driving source is transmitted to a feed roller shaft 116a at the lower side, thus the roller 116 is driven. Next, when a feed roller 115 at the upper side is driven, if the solenoid 74 is energized with current, the tip end side of the arm 72 is attracted to the solenoid 74 and operates the side of a rolling clutch member 20, moving the selector member 20 to the side of this member 20. Therefore, toothed parts 30b and 20a are engaged with each other, whereby rotational force of the driving source 50 is transmitted to a feed roller shaft 115a at the upper side, driving the roller 115. Thus, a device can be made into miniaturization and lightweightiness.
