Abstract
Abstract A data recording device for camera which comprises a keyboard and display section which is set in a camera in light communication with a film frame, and emits light in accordance with data supplied by the actuation of a keyboard in response to the operation of a shutter release. This data recording device further comprises a memory circuit for causing data supplied by operation of the keyboard to be stored in the address corresponding to an output signal from the frame number indicating means. When a shutter release is operated, data is read out from the address of the memory circuit corresponding to an output signal from the frame number counter. The display section is actuated in accordance with data thus read out, thereby making it possible to previously specify data to be recorded on a given film frame.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
170 words
A data recording device for camera comprising: frame number selecting means which is provided with an operation member and sends forth a signal denoting a serial number of a given film frame by actuating the operation member thereof; data generating means which is provided with an operation member and issues a signal representing a given data by actuating the operation member thereof; memory means connected to said frame number selecting means and data generating means for causing data corresponding to the data signal to be stored in an address corresponding to a frame number signal; counting means which is operated in response to a shutter operation of a camera, and emits a count singal representing the number of operation times of the shutter; and light emitting means providing in a camera in light communication with a film frame and connected to the memory means and to the counting means for emitting light in accordance with data stored in the address of the memory means which corresponds to the count signal.
Claim 2
Dependent Claim
170 words
A data recording device for camera comprising: frame number selecting means which is provided with an operation member and sends forth a signal denoting a serial number of a given film frame by actuating the operation member thereof; data generating means which is provided with an operation member and issues a signal representing a given data by actuating the operation member thereof; memory means connected to said frame number selecting means and data generating means for causing data corresponding to the data signal to be stored in an address corresponding to a frame number signal; counting means which is operated in response to a shutter operation of a camera, and emits a count singal representing the number of operation times of the shutter; and light emitting means providing in a camera in light communication with a film frame and connected to the memory means and to the counting means for emitting light in accordance with data stored in the address of the memory means which corresponds to the count signal.
Claim 3
Dependent Claim
135 words
The data recording device according to claim 1, further comprising: operation mode changing means which is connected to the memory means, and, at a first operation mode, sets the memory means in a state ready for the writing of data, and at a second operation mode, sets the memory means in a state preventing the writing of data; and display means which is mounted on the outer wall of a camera body and emits a light in accordance with data stored in the address of said memory means corresponding to the film frame number signal when said memory means is set in the first operation mode, and in accordance with data stored in the address of the memory means corresponding to a count signal when said memory means is set in the second operation mode.
Claim 4
Dependent Claim
73 words
The data recording device according to claim 2, further comprising switching means which is connected between said memory means and said light emitting means, and, at said first operation mode of said operation mode changing means, allows data stored in said memory means to be transmitted to said light emitting means, and, at a second operation mode of said operation mode changing means, prevents said transmission of data to said light emitting means.
Claim 5
Dependent Claim
22 words
The data recording device according to claim 1, wherein said light emitting means is provided behind a film frame in a camera.
