Abstract

An image capturing apparatus includes a main unit including an optical unit for acquiring an image of an object, and a photographing unit for photographing the image acquired by the optical unit as image data by optical-to-electronic conversion; and a replacement unit including an image recording unit for storing the image data photographed by the photographing unit, and a number information storing unit for storing information specifying a number of images stored in said image recording unit, wherein the replacement unit is detachably mounted on the main unit.

Claims

1. An image capturing apparatus comprising:

a main unit comprising an optical unit for acquiring an image of an object, and a photographing unit for photographing said image acquired by said optical unit as image data by optical-to-electronic conversion; and

a replacement unit comprising an image recording unit for storing said image data photographed by said photographing unit, and a number information storing unit for storing information specifying a number of images stored in said image recording unit, said replacement unit being detachably mounted on said main unit.

2. An image capturing apparatus as claimed in claim 1, wherein said replacement unit forms a portion of external housing of said photographing apparatus.

3. An image capturing apparatus as claimed in claim 1, wherein said replacement unit further comprises a battery for driving said main unit.

4. An image capturing apparatus as claimed in claim 1, wherein said replacement unit further comprises an outputting unit for outputting said stored image data.

5. An image capturing apparatus as claimed in claim 1, wherein said replacement unit further comprises a convex or concave portion in order for a user to grasp said photographing apparatus easily.

6. An image capturing apparatus as claimed in claim 1, wherein said photographing apparatus further comprises:

a setting unit for storing a predetermined possible storage number in a range of one (1) to a number of storable images determined by a capacity of said image recording unit; and

an image reception determining unit for refusing to store said image data in said image recording unit in case that a number specified by number specifying information stored in said number information storing unit is not smaller than said possible storage number stored in said setting unit, and permitting to store said image data in said image recording unit in case that said specified number is smaller than said possible storage number.

7. An image capturing apparatus as claimed in claim 6, wherein said number information storing unit stores key information of which the number is the same with said possible storage number, and changes said key information into a format indicating use-ending whenever said photographing unit outputs said image data to said image recording unit.

8. An image capturing apparatus as claimed in claim 1 further comprising:

a battery for driving said main unit;

a setting unit for storing a predetermined possible storage number in a range of one (1) to a number of storable images determined by a capacity of said image recording unit; and

a power supply determining unit for stopping supplying power from said battery in case a number specified by number specifying information stored in said number information storing unit is not smaller than said possible storage number.

9. An image capturing apparatus as claimed in claim 7, wherein said battery, said setting unit and said power supply determining unit are provided in said replacement unit.

10. A replacement unit for an image capturing apparatus, which is detachably mounted on a main unit comprising an optical unit for acquiring an image of an object and a photographing unit for photographing said image acquired by said optical unit as image data by optical-to-electronic conversion, the replacement unit comprising:

an image recording unit for storing said image data photographed by said photographing unit;

a number information storing unit for storing information specifying a number of images stored in said image recording unit; and

a battery for driving said main unit.

11. A replacement unit of an image capturing apparatus as claimed in claim 10, further comprising an outputting unit for outputting said stored image data.

12. A replacement unit of an image capturing apparatus as claimed in claim 10, further comprising a convex or concave portion in order for a user to grasp said photographing apparatus easily.

13. A replacement unit of an image capturing apparatus as claimed in claim 10 further comprising:

a setting unit for storing a predetermined possible storage number in a range of one (1) to a number of storable images determined by a capacity of said image recording unit; and

an image reception determining unit for refusing to store said image data in said image recording unit in case that a number specified by number specifying information stored in said number information storing unit is not smaller than said possible storage number stored in said setting unit, and permitting to store said image data in said image recording unit in case that said specified number is smaller than said possible storage number.

14. A replacement unit of an image capturing apparatus as claimed in claim 13, wherein said number information storing unit stores key information of which the number is the same with said possible storage number, and changes said key information into a format indicating use-ending whenever said photographing unit outputs said image data to said image recording unit.

15. A replacement unit of an image capturing apparatus as claimed in claim 10, further comprising:

a setting unit for storing a predetermined possible storage number in a range of one (1) to a number of storable images determined by a capacity of said image recording unit; and

a power supply determining unit for stopping supplying power from said battery in case a number specified by number specifying information stored in said number information storing unit is not smaller than said possible storage number.
