Abstract

Camera apparatus including a loading detection sensor for detecting the completion of the loading of a solid-state memory cartridge, a contact member for contacting electric contacts on the cartridge for communicating data between the camera and the cartridge, and a communication control circuit for starting data communication between the memory cartridge and the camera when the loading detection sensor detects that the cartridge has been installed. The contact member moves from a first position at a distance from the memory cartridge contacts to a second position contacting the memory cartridge contacts.

Claims

1. Camera apparatus comprising:

loading detection means for detecting completion of loading of a semiconductor memory cartridge in the camera, the memory cartridge being detachable from said camera;

communication means for communicating data between the memory cartridge and said camera, said communication means having a plurality of electrodes which contact a corresponding plurality of electrodes of the memory cartridge in response to the loading of the memory cartridge in said camera;

electrode moving means for moving said electrodes of said communication means from a position apart from a loading path of said memory cartridge to a position at which said electrodes of the communication means contact the electrodes of the memory cartridge in response to loading of the memory cartridge;

control means, provided in said camera, for starting data communication between said camera and the memory cartridge by said communication means when said loading detection means detects the completion of the loading of the memory cartridge; and

display means for displaying information provided from the memory cartridge immediately after the cartridge is detected as being inserted by said loading detection means, said display means being integral with said camera and being controlled by said control means.

2. Apparatus according to claim 1, further comprising:

(d) imaging means for receiving image information and converting it into an electric signal; and

(e) signal processing means for converting the electrical signal of said imaging means into a form storable within the semiconductor memory cartridge.

3. Apparatus according to claim 2, further comprising a cartridge-housing unit coupled to said camera, for holding the memory cartridge, and wherein said loading detection means comprises a switch disposed within said cartridge-housing unit.

4. Apparatus according to claim 1, wherein said communication means comprises plural electric contacts connected to one another by the loading of the memory cartridge.

5. A camera comprising:

loading detection means for detecting completion of loading of a removable solid-state memory cartridge into the camera;

connection means for providing a communication channel for data between the memory cartridge and the camera, said communication means having a plurality of electrodes which contact a corresponding plurality of electrodes of the memory cartridge responsive to the loading of the memory cartridge in said camera;

electrode moving means for moving said electrodes of said connection means from a position apart from a loading path of said memory cartridge to a position at which said electrodes of said connection means contact the electrodes of the memory cartridge in response to loading of the memory cartridge;

control means, integral with said camera, for controlling said connection means in response to the detection by said loading detection means to provide said communication channel between the memory cartridge and said camera, and for starting data communication between the memory cartridge and said camera via said communication channel; and

display means for displaying information provided from the memory cartridge immediately after the cartridge is detected as being inserted by said loading detection means, said display means being integral with said camera and being controlled by said control means.

6. A camera according to claim 5, wherein said solid-state memory cartridge comprises a semiconductor memory which can store a plurality of image information.

7. A camera according to claim 6, further comprising:

(d) imaging means for receiving image information and converting it into an electric signal; and

(e) signal processing means for converting an output signal of said imaging means into a form storable within the semiconductor memory cartridge.

8. A camera according to claim 5, wherein said loading detection means includes an operation member which moves in accordance with the loading operation of the memory cartridge, and moves said connection means toward the electrode of the memory cartridge when the cartridge is loaded.

9. A camera according to claim 8, wherein said loading detection means includes a switch which is turned on and off by the operation of said operation member.

10. A camera according to claim 9, wherein said control means starts data communication between said camera and said memory cartridge via said communication channel when said switch is turned on.

11. A camera comprising:

(a) a movable connection electrode which moves from a first position apart from a path of a removably mounted semiconductor memory cartridge to a second position connectable to the electric contact of the removably mounted memory cartridge by a loading operation of the semiconductor memory cartridge;

(b) a switch for detecting the movement of said connection electrode to said second position; and

(c) a control circuit, integral with said camera, for starting data communication between said camera and the semiconductor memory cartridge when said switch detects that the connection electrode has moved to the second position; and

(d) display means for displaying information provided from the memory cartridge immediately after the cartridge is inserted, said display means being integral with said camera and being controlled by said control circuit.
