Title:
MOTOR DRIVING DEVICE FOR CAMERA
Document Type and Number:
Japanese Patent JPS6214134
Kind Code:
A
Abstract:

PURPOSE: To simplify rewinding operation by forming a connecting/disconnecting means for turning a rewinding drive transmitting mechanism to a transmission state on the basis the rotational driving force of a motor in a prescribed direction and a rewinding setting mechanism for driving a rewinding setting operation part in a camera body.

CONSTITUTION: A reversing circuit 34 outputs a HIGH signal in accordance with the closing of a normally-opened switch S4. The output terminal of the circuit 34 is connected to the base of a transistor (TR) T4 for turning on/off a relay switch RL4, and when the circuit 34 outputs the HIGH signal, the TR T4 is connected, the switch RL4 is turned on and the motor M is reversed. When the switch RL4 is turned on, base current flows into the TR T4 and the connected state is held. A mode setting circuit has opening and closing switches S8, S9 to switch the winding mode to a high speed continuous winding mode, a low speed continuous winding mode or an one-frame winding mode in accordance with the setting state by a winding operation mode setting member 16.
