Lens apparatus diagnostic system, diagnostic program, record medium, lens diagnostic system and controller diagnostic system

A lens diagnostic system for performing an offset diagnosis of a lens drive apparatus having a control signal outputting device which outputs a control signal of a value according to a setup position of an operating member and a driving device which drives a movable optical element of the lens apparatus to be in a state corresponding to the value of the control signal, the system comprising:

• a control signal detection device which detects the value of the control signal outputted by the control signal outputting device;
• a follow signal outputting device which outputs a follow signal for indicating the state of the movable optical element;
• a first determination device which, in the state where the operating member is set up at a setup position determined to have the movable optical element set up in a predetermined state, determines whether or not the value of the control signal detected by the control signal detection device meets the condition of being within a range of standard values allowed as the values for setting up the movable optical element in the predetermined state;
• a second determination device which, in the state where the operating member is set up at a setup position determined to have the movable optical element set up in a predetermined state, determines whether or not the value of the follow signal outputted by the follow signal outputting device meets the condition of being within the range of the standard values allowed as the values for indicating the predetermined state of the movable optical element;
• and
• a diagnostic device which diagnoses it as normal in the case where both the first and second determination devices determine that the conditions are met, diagnoses the control signal outputting device as abnormal in the case where, of the first and second determination devices, at least the first determination device determines that the condition is not met, and diagnoses the driving device as abnormal in the case where, of the first and second determination devices, only the second determination device determines that the condition is not met.

• a control signal detection device which detects the value of the control signal outputted by the control signal outputting device;
• a follow signal outputting device which outputs a follow signal for indicating the state of the movable optical element;
• an output voltage detection device which detects the voltage of the analog voltage signal outputted by the signal processing device;
• a first determination device which, in a state where the operating member is set up at a setup position determined to have the movable optical element set up in a predetermined state, determines whether or not the value of the control signal detected by the control signal detection device meets the condition of being within a range of standard values allowed as the values for setting up the movable optical element in the predetermined state;
• a second determination device which, in the state where the operating member is set up at the setup position determined to have the movable optical element in the predetermined state, determines whether or not the value of the follow signal outputted by the follow signal outputting device meets the condition of being within the range of the standard values allowed as the values for indicating the predetermined state of the movable optical element;
• a third determination device which, in the state where the operating member is set up at the setup position determined to have the movable optical element set up in the predetermined state, determines whether or not the voltage detected by the output voltage detection device meets the condition of being within the range of the standard values allowed as the values for setting up the movable optical element in the predetermined state;
• and
• a diagnostic device which diagnoses it as normal in the case where all of the first, second and third determination devices determine that the conditions are met, diagnoses the control signal outputting device as abnormal in the case where, of the first, second and third determination devices, at least the first determination device determines that the condition is not met, diagnoses the signal processing device as abnormal in the case where the first determination device determines that the condition is met and, of the second and third determination devices, at least the third determination device determines that the condition is not met, and diagnoses the driving device as abnormal in the case where, of the first, second and third determination devices, only the second determination device determines that the condition is not met.

A lens apparatus diagnostic system which diagnoses a lens apparatus, the system comprising:

• a data storage device which automatically records diagnostic results obtained by diagnosis of the lens apparatus as diagnostic history data at least with date information on a record medium, and records and stores the diagnostic history data of the diagnoses performed in past;
• a diagnostic history display instruction device which provides an instruction to display diagnostic history;
• and
• a diagnostic history list display device which, if instructed to display diagnostic history by the diagnostic history display instruction device, reads the diagnostic history data of the past recorded and stored on the record medium by the data storage device from the record medium and list-displays the read diagnostic history data.
