Battery supplying apparatus for camera
First Claim
1. In an electric power supply system for a camera including a camera body employing a large load circuit with a flash lamp and a signal processor, and at least a removable, primary power supply package accommodating a primary battery serving as an electric power supply for said camera, the improvement comprising:
- first terminal means disposed on said power supply package for connecting said primary battery to said large load circuit and to said signal processor;
voltage stabilizer means disposed on said power supply package to compensate for voltage fluctuations caused by said flash lamp;
said first terminal means including a first positive terminal connected through said voltage stabilizer means to a positive electrode of said primary battery, a second positive terminal connected to said positive electrode of said primary battery, and a minus terminal connected to a negative electrode of said primary battery; and
second terminal means disposed on said camera body for connecting said primary battery to said large load circuit and to said signal processor;
said second terminal means including a first input terminal for said signal processor connected through said first positive terminal via said voltage stabilizer means to said positive electrode of said primary battery, a second input terminal for said large load circuit connected through said second positive terminal to said positive electrode of said primary battery, and a minus terminal for said large load circuit and said signal processor connected through said minus terminal of said package to said negative electrode of said primary battery.

Abstract
An electric power supply system for a camera that includes a camera body containing a charging circuit for a stroboscope and a signal processor, and at least a primary battery type of power supply package accommodating a primary battery electrically connected by terminals disposed on the package and terminals disposed on the camera body. The terminals of the package include a first positive terminal connected through a voltage stabilizer to the positive electrode of the primary battery, a second positive terminal connected to the positive electrode of the primary battery, and a minus terminal connected to the negative electrode of the primary battery. The terminals of the camera body include a first input terminal for the signal processor connected through the first positive terminal via the voltage stabilizer to the positive electrode of the primary battery, a second input terminal for the charging circuit connected through the second positive terminal to the positive electrode of the primary battery, and a minus terminal for the signal processor and the charging circuit connected through the minus terminal of the package to the negative electrode of the primary battery.

5. An electric power supply system for a camera comprising:
-
image pick-up means for generating a signal representing an image in a field of view of the camera; a signal processor for processing the signal from said image pick-up means into a recordable signal; recording means for recording the recordable signal from said signal processor onto a recording medium; strobe means for emitting stroboscopic light, said strobe means including a charging circuit being capable of supplying a large current for exciting a lamp to generate the stroboscopic light; means for selectively holding a first battery package having a battery with known internal resistance or holding a second battery package having a battery with an internal resistance smaller than said known internal resistance where said first battery package and said second battery package have substantially identical dimensions; discriminating means for determining whether said first battery package or said second battery package is held by said means for holding; and voltage stabilizer means for stabilizing a voltage output from said first battery package and producing a substantially constant output voltage, wherein said signal processor receives the constant voltage from said voltage stabilizer when said discriminating means determines that said means for holding holds said first battery package. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
