Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrophotographic apparatus designed to obtain the following characteristics.In particular, the present invention relates to a removable unit type electrophotographic apparatus in which a recording and sickle reproducing section is unitized.

Figure 1 shows a conventional electrophotographic device (hereinafter referred to as an electronic camera)
FIG. @1 As shown in Figure 1, the light incident from lens 1 passes through an aperture mechanism (not shown),
The light passes through a shutter, etc., and further passes through a half mirror 2 to reach a solid-state emotional element 3, and forms an image of the subject on this image sensor. In addition, the light that is lost in the half mirror 2 is guided to the finder 5 by the i-lase, allowing you to determine the field of view, etc.

The object l formed on the solid-state image sensor s is successively scanned by the dry 1 circuit 6, and then roughly scanned by the video circuit 7.
After the video signal is converted into a video signal, it is supplied to the recording head 8. The recording head 8 records image information on the recording surface of the disk 9 while being driven in the radial direction of the magnetic disk 9 as indicated by arrows in the figure by a drive mechanism (not shown). The magnetic disk 9 is loaded into the camera body from the outside and is rotationally driven by a motor 10. The Naori Mera main body 11 is equipped with a battery 1 as a power source.
2 is housed tightly, and the power supply can be operated using the power switch 13.

The conventional electronic camera having the above configuration has the following problems. In other words, the record of great information! The disk 9 as a recording medium that performs seven recordings, a motor 101 for rotating the disk 9Yr, and a drive mechanism for driving the recording head 8 must be installed inside the camera body.
The camera body becomes large and heavy. As a result, there is a problem in that it is difficult to reduce the size and weight, which is the most important requirement in realizing a portable electronic camera. Furthermore, if the motor 10, which is the drive source for the disk 9, comes close to the solid-state image sensor 3, it will cause noise generation, so it is necessary to keep the motor 10, etc. sufficiently far away from the solid-state image sensor 3, and the arrangement of each component is very difficult. It's difficult. Furthermore, in order to reproduce the recorded image information, one is taken out from the camera body 11 on the disk 9, and then a separate reproduction device 14 is installed as shown in FIG.
It is necessary to load it into the computer and display it on the monitor display 15. For this reason, there is a problem that not only the playback operation is complicated, but also the playback device 14 must be prepared separately. In addition, when remotely controlling an electronic camera, not only the imaging unit but also the recording means must be remotely controlled, which results in a large diameter control cable, which causes some difficulty in handling. For this reason, the reality is that remote control cannot be performed with conventional electronic cameras.

The present invention has been made in consideration of these circumstances, and its purpose is to make the camera body small and lightweight, which makes it possible to easily realize a small portable electronic camera, and to eliminate the noise caused by the disk drive source. A removable unit type electrophotographic device that has almost no components, allows for easy parts arrangement within the camera body, does not require a special playback device, allows playback operations to be performed immediately after recording, and can be easily controlled remotely. The goal is to provide the following.

In other words, the present invention allows the recording and reproducing section of a disk or the like to be housed separately in a unit that is detachable from the camera body. It is possible to use the camera body housing only the unit and the unit separately from the unit housing the recording/playback section. It is characterized in that it can be used as a control device and a recording/reproducing device.
