Why does the picture count on my DSC-HX9V revert to number 1?

Hi,

I use my Sony Cyber-shot DSC-HX9V for taking approx 650 Lots each fortnight at my auction house, I need a running total of pictures taken ,however ,on both occasions I have used the camera the picture counter has reverted to number one. The first time I had taken 385 pictures then the counter reverted to number one, the second time I had reached 212 pictures before the counter again reverted to number one. On each occasion the file size was the same & the picture mode was the same. Any ideas on what is the cause of this happening?
