Detailed Description of the Invention 3. Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a playback device for an electronic still camera.

[Prior art and its problems] First, some sub-still cameras have been proposed that are equipped with a display device so that images of recorded subjects can be monitored on the spot (for example, Japanese Patent Laid-Open Publication No. 6
No. 0-160278).

In this proposal, electronic still cameras are used for television (TV).
It also functions as a receiver, and the camera and receiver are integrated into one unit.

Originally, electronic still cameras and TV receivers are both heavy and relatively bulky, so
Devices that combine both functions are particularly heavy and large, making them difficult to operate and carry; It was inconvenient and difficult to use.

[Object of the invention] This invention was made in view of the above-mentioned circumstances, and its purpose is to make the still camera itself compact so that it can be used both as a camera and a TV receiver, and to improve its operation. An object of the present invention is to provide a still camera playback device that is excellent in performance and portability.

[Summary of the Invention] In order to achieve the above-mentioned object, the present invention configures a TV receiver to be detachably attached to a camera section, and, if necessary,
The key point is that the TV receiver can be attached to a camera section and the camera section can have a player section, or the TV receiver can be removed to watch television.

[Example] Hereinafter, an example of the present invention will be specifically described with reference to the drawings.

Additionally, a volume switch 12 is located above the speaker 11.
and a tuner switch 13, and an antenna 1 on the top.
4 are provided, and these have the same configuration as an ordinary liquid crystal television.

Also, on the back side of the TV receiver 9, as shown in FIG. 2B, when the TV receiver 9 is housed in the TV receiver storage part 7 so that the back side is joined to the back side of the case body 1, a camera, which will be described later, is provided. An image terminal 16 is provided as a data transmission means for receiving a reproduced image signal from a floppy disk on the side, and therefore, there is also an image terminal used as a pair at a position δ corresponding to the image terminal 16 on the camera side. 26 (FIG. 5) is provided. Further, a projection 17 and a switch 18 are provided at the bottom of the image terminal 16.
7 and the switch 18 are provided on the camera side when the TV receiver 9 is stored in the RV2 receiver storage section 7, as will be described later in detail with reference to FIGS. 3 and 4. The protrusion 17 closes the switch contact on the camera side to switch the camera to playback mode, and the switch 18 closes the switch contact on the TV side to switch the camera to the camera via the image terminal 16. It is designed to switch to a mode in which the reproduced image signal received from the side is reproduced and displayed.

FIGS. 3 and 4 are for explaining the configuration of the protrusion 17 and switch 18 in FIG. 2B, and how they interact with the configuration of the camera when the TV receiver 9 is housed in the camera. In particular, FIG. 3 shows the state before storage, and FIG. 4 shows the state after storage. In the drawings, the upper side is the TV side and the lower side is the camera side.

As can be seen from the drawing, the square protrusion 17 is the case 20.
It is integrally formed as a part of the

The switch 18 is made of an elastic and insulating material such as rubber, which is stretched along the inside of the case 20, and has a relatively thin part 18a and a rectangular side that extends from both sides of the part 18a. Consisting of protruding parts 18b and 18c, and a conductive movable contact 21 affixed to the top surface of the protruding part 18c with a suitable adhesive, the protruding part 18b is inserted through a spacious opening provided in the case 20. It protrudes to the outside. Thus, when the protruding portion 18b of the switch 18 is pushed inward, the movable contact 21 short-circuits the stationary contact 23 and the stationary contact 24 provided on the substrate 22, thereby functioning as a switch.

On the other hand, if you look at the camera side, there is a protrusion 1 on the TV side.
A switch 27 having the same configuration as that described in connection with the switch 18 is provided at a position corresponding to 7, and a protrusion 28 similar to the protrusion 17 is provided at a position t corresponding to the switch 18 on the TV side. There is. Therefore, when the switch 27 is pushed in, the movable contact 29 provided on the internal protrusion of the switch 27 short-circuits the stationary contacts 31 and 32 provided on the board 30, and Establish continuity.

As can be expected from the above description, the protrusion 17 and the switch 27, and the switch 18 and the protrusion 28 are eventually used as a pair, and the TV receiver 9 is housed in the TV receiver housing 7 of the camera (FIG. 4). In this case, the protrusion 17 pushes the switch 27 to short-circuit between the stationary contact 31 and the stationary contact 32, and the protrusion 28 pushes the switch 18 to short-circuit the stationary 1h contact 23.
and the stationary contact 24.

FIG. 5 shows the overall circuit configuration of this embodiment, in which the left side surrounded by the dashed line shows the camera side 35, and the right side shows the television side 36.

On the camera side 35, a system control section 37 controls the entire circuit, and reads instruction data such as shutter time, aperture priority, shutter priority, program, etc. from an information setting section 38 consisting of a setting data input switch. , perform the necessary processing.

In addition, the system control ffl 37th sends a drive signal to the shutter control unit 40 in response to a shirt release command from the shutter switch 39, and controls the shutter 41.
is opened, so the light ray A from the subject is directed to the imaging lens 4.
The image sensor 43 in this embodiment is composed of COs arranged in a matrix.
D, one scene of the subject image is imprinted at a time,
By detecting the density distribution of this subject image, the image formed thereon is converted into a frL signal. That is, the horizontal and vertical data corresponding to the image imprinted on the image sensor 43 are generated in the synchronization signal generator 44 and sent to the image sensor 4 via the drive section 45.
The signal is extracted by the clock signal supplied to the imaging signal processing circuit 46 and is supplied to the imaging signal processing circuit 46.

The signal converted into a format suitable for recording by the image pickup signal processing circuit 46 is supplied to the head section 49 via the recording amplifier 47 and the recording/playback switching section 48, and the signal is sent to the head section 49 to produce one image per track on the floppy disk 50. Recorded as data. Note that the imaging signal processing circuit 46 is driven and controlled by a clock signal from the synchronization signal generating section 44.

Further, the system control unit 37 controls a switch 56 for recording or reproducing image data on the floppy disk 50.
When reproducing image data from the floppy disk 50 by the operation, a servo M control signal is supplied to the servo control unit 51 to rotate the motor 52, and
At the end of recording or reproducing image data for a track, a head control signal is given to the head control section 53 to slide the head section 49 to the next track position.

The image data signal read from the floppy disk 50 by the head section 49 is amplified by the reproduction amplifier 54, and then converted into a format suitable for display by the reproduction image signal processing section 55 and output to the image terminal 26. Ru.

On the television side 36, video and audio radio waves captured by a receiving antenna 57 are provided to a tuner IF amplifier 58. In this tuner IF amplification unit 58, a radio wave of a designated channel is selected, and regardless of the reception channel, it is always converted into a video and audio intermediate frequency signal of a constant frequency, amplified, and detected. This signal is
On the one hand, the low frequency is amplified by the audio amplifying section 59 and emitted by the speaker 60, and on the other hand, the video signal amplifier 61
is amplified to the required size.

The output of the video signal amplifier 61 is input to the synchronization circuit 63 via the mode changeover switch 62, where the synchronization signal is separated, and the output is converted to a digital signal by the A/D converter 64. 216
6 and is reproduced as an image by a synchronization signal sent from the synchronization circuit 63 via a driver 67.

In this case, since the matrix display device 66 is configured as an LCD, the TV receiver 9 can be made quite compact.

[Operation of the Embodiment] Next, as previously explained in connection with FIGS. 1 to 4,
If the TV receiver 9 is attached to the camera side, the switches 18 and 27 are closed, and at the same time the image terminal 16.2 is closed.
6 are electrically connected.

Thus, on the television side 36, in response to the closing of the switch 18, the mode selector switch 62 is set to the dotted line side! 7J can be replaced. Furthermore, on the camera side 35, the system control 37 detects that the switch 27 is open, and switches the recording/reproduction switching section 48 to the reproduction side shown by the dotted line.

As a result, the image data signal read from the floppy disk 50 by the head section 49 is amplified by the reproduction amplifier 54, and then the data is converted into a format suitable for input to the television side 36 by the reproduction image signal processing section 55. After undergoing processing such as conversion, it is input to the TV side 36 via the image terminal 26.16, and on the TV side 36, the A/D
Processing such as conversion and timing control is applied. As a result, the matrix display section F! 166 contains image data for one track on the floppy disk 50, that is, one
The image of the subject is reproduced and displayed.

In this way, by storing the TV receiver 9 in the TV receiver storage section 7 of the camera section only when a refurbished device is required, the TV receiver 9 automatically becomes a monitor display section.
The image data already recorded on each track of the floppy disk 50 of the camera section will be displayed, and when taking pictures, you only need to bring the camera body.

[Effects of the Invention] As described in detail above, the present invention has a 4R configuration in which the TV receiver is attached to and detaches from the still camera section, and the TV receiver when attached to the camera section receives TV radio waves. Since the output from the camera section can be switched from the state in which the output is input to the state in which the output from the camera section is input, it is easy to handle due to the reduction in weight when used separately, has good portability, and also because of the high frequency of use separately. Not only can the resulting high utilization rate be enjoyed, image data already recorded in the camera section can be reproduced and displayed as needed, and the TV receiver can also be used repeatedly as a standalone TV receiver.

Figures 2A and 2B are front and rear perspective views of the TV receiver attached to the camera;
FIG. 4 is a partially extracted sectional view for explaining the mechanical and electrical connection state when the TV receiver is attached to the camera.

In particular, FIG. 3 shows the state before installation, FIG. 4 shows the state after installation, and FIG. 5 shows the overall circuit configuration of this embodiment.
