Abstract
PURPOSE: To make possible checking of film winding by detecting the load to be applied upon a motor with a switching member.
CONSTITUTION: When a motor M runs and a film or the like is being normally wound, the magnetic force of a current detecting element L by its load current becomes above the specified and when the switch member Sl of the display circuit closes, display is accomplished and when it opens, the display goes OFF, whereby checking of normal winding is performed. When the motor M is idling, the magnetic force of the current detecting member L by its load current does not each the specified and the switch member Sl of the display circuit opens to put out the display, from which the idling of the motor may be known. In this way, checking of the film winding is made possible.
