2. Description of the Related Art A still video camera device is called a so-called Mavica. As shown in FIG. 13, a recess 10D is formed in a part of the bottom surface 10C of the still video camera apparatus main body 10 so that a battery 60 can be housed and connected. This recess 10D includes a battery terminal electrode 110.
, 111, and four battery lock installation guides 117A to 117D are provided. The elastic force acting on the battery terminal electrodes 110 and 111 is biased toward the connection surface 62 of the battery 60 by a spring disposed within the still video camera apparatus main body 10. Since the battery 60 presses the battery terminal electrodes 110 and 111 when disposed in the recess 10D, each electrode is housed within the still video camera apparatus main body 10.

[Problem to be Solved by the Invention] By the way, if it is considered to transmit data from a still video camera device via a general telephone line or digital line, a still picture transmitter is required. become.

For this reason, it is conceivable to simply integrate the still video camera device and the still image transmitter, but the size of the still image transmitter would become too large. Even if the above-mentioned still image transmitter is used as an adapter, a new area must be provided somewhere in the main body of the still video camera apparatus for the connection part. Securing this new connection area poses a problem in terms of space.

[0006]Furthermore, when the still video camera device is used only for photographing and does not require electric transmission, the still video camera device integrated with the still image electric transmitter is large in size and has poor operability. Furthermore, when considering a power transmission adapter as a substitute for the still image transmission device, the power transmission adapter has a fairly large-scale circuit configuration, so for example, a new IC is required to prevent the power transmission adapter from becoming too thick. The need also arises. This use of IC leads to an increase in the cost of the still video camera device.

In view of the above-mentioned circumstances, the present invention has been developed to provide a compact and lightweight still video camera with good maneuverability, in which the power transmission adapter can be separated according to the necessity of power transmission, and which can also perform photographing and data transmission with good operability. The object of the present invention is to provide a still video camera device that is capable of providing a high-performance still video camera device.

[0008]

In the camera device, a power transmission adapter for electrically transmitting a video signal obtained from the still video camera body to the outside via a telephone line is provided at a mounting portion of the still video camera body to which the battery is attached, and a power transmission adapter is disposed in the power transmission adapter. and the battery that supplies power to the power transmission adapter and the still video camera body via a terminal, the power transmission adapter being connected between the battery and the still video camera body, and further comprising: The above problem is solved by forming the electrical transmission adapter so that the contact area when connected to the still video camera body is larger than the contact area when the battery is connected to the still video camera body. do.

[0009]

[Operation] In the still video camera device according to the present invention, the power transmission block section and the battery section are arranged and housed integrally so that the connection points on the main body of the device can be shared.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a still video camera apparatus according to the present invention will be described with reference to FIG. The still video camera device shown in FIG. 1 is a simplified block diagram. This charge-coupled device (CCD) 11 shown in FIG. 1 converts the light captured by each pixel into an electrical signal and supplies this output signal to the camera block 12. This camera block 1
2 converts the output signal of the image sensor into a video signal. The output video signal from this camera block 12 is supplied to a recording system 13. This recording system 13 is a recording block, switch 15
, an amplifier 17, and a head 18.

First, the output video signal from the camera block 12 described above is supplied to a recording block 14 which converts it into a recording signal. This recording block 14 modulates the supplied output video signal from the camera block 12, outputs it as a recording signal, and supplies this signal to a terminal 15a of a switch 15 for selective switching. Here, the terminal 15a of this switch 15 corresponds to a first position which will be described later. In this way, the output recording signal of the recording block 14 is amplified by the amplifier 17, which is the recording means, via the switch 15, and is recorded on the magnetic disk, which is a recording medium, via the head 18.

On the other hand, the reproduction system 20 is composed of the above-mentioned head 18, amplifier 17, switch 15, and reproduction block 21 in the order of signal flow. In this reproducing system 20, a reproduced signal is extracted and supplied to an amplifier 17 via a head 18, which is a reproducing means for reproducing recorded information recorded on a magnetic disk. This amplifier 17 amplifies the supplied reproduction signal and supplies it to the switch 15. This output signal is selectively switched to the terminal 15b of the switch 15 as described later and is supplied to the reproduction block 21. This reproduction block 21 demodulates the reproduction signal supplied via the switch 15 and outputs a video signal. This output video signal is supplied to a terminal 16b of a selectively switching switch 16. The other end 15b of the switch 15 and the terminal 16b of the switch 16 described above correspond to a second switching position described later. In this still video camera device, the amplifier 17 and head 18 of the recording system 13 and the reproducing system 20 are used in common.

As described above, the output recording signal from the recording block 14 is supplied to the recording means, and the output video signal from the camera block 12 is supplied to the electric transmission block 22 for electric transmission via the telephone line. It is supplied to the terminal 16a of the switch 16. Here, the terminal 16a of the switch 16 corresponds to the first switching position. The output video signal is supplied to the electric transmission block 22 via this switch 16. This transmission block 22 modulates the supplied video signal into an audio band signal and outputs it to the modular jack 23. As will be described later, the modular jack 23 is connected to a public telephone and transmits the signal via the telephone line.

[0014] At this time, the photographed video signal can be directly transmitted electronically without causing the signal deterioration that occurs when it is once recorded on a recording medium. Here, the above-mentioned switches 15 and 16 are switched, for example, by providing a switch operating section on the outer casing of the camera body, and selectively interlocking the signals supplied to each block. At this time, the first switching position means that the output recording signal of the recording block 14 is transferred to the amplifier 17 as described above.
Terminal 15b of the switch 15 that supplies the output video signal of the camera block to the transmission block, and terminal 16a of the switch 16 that supplies the output video signal of the camera block to the transmission block. Also,
The second switching position refers to a position on the terminal 15b side of the switch 15 that supplies the above-mentioned reproduction signal to the reproduction block 21 and the terminal 16b side of the switch 16 that supplies the output video signal of the reproduction block to the transmission block. It is.

[0015] Also, the switch 1 which is the switching means described above
5 and 16, when located at the first switching position,
When the output video signal of the camera block 12 is supplied and the camera block 12 is located at the second switching position, the output video signal of the reproduction block 21 is supplied. Finder 25
(hereinafter abbreviated as EVF) is also supplied to an EVF block 24 that drives the EVF. In the EVF block 24, the drive signal is
It is possible to display the image on the VF 25 and monitor still images during shooting or playback using the EVF 25. Note that the viewfinder section of the camera that monitors this still image is not limited to the EVF 25 mentioned above, but can be substituted by outputting to a small liquid crystal externally provided through an output terminal, or a television such as a cathode ray tube, for example. You may let them.

[0016] Furthermore, the recording medium for storing the photographed recording signal is not limited to a magnetic disk. If the camera used for photographing is a digital still camera, a semiconductor memory or a magneto-optical disk may be used. good. With this configuration, this still video camera device can directly transmit a captured video signal by electronic means without signal deterioration caused by once recording it on a recording medium. Further, the configuration of the above-described still video camera apparatus can be changed to a block configuration in which the electric transmission block 22 is connected after the reproduction block 21 of the reproduction system 20 to transmit electric power, as shown in FIG.

In FIG. 2, parts common to the configuration of FIG. 1 described above are given the same reference numerals, and explanations thereof will be omitted. If an optical viewfinder was used in this still video camera device, it was not possible to monitor the still images taken by the camera itself during playback. Still images taken by the camera itself can be viewed on the EVF 25 provided on the camera body, which simplifies the effort of carrying the monitor.

The actual usage of a still video camera device having such a configuration will be explained with reference to FIGS. 3 to 5. Further, the description will be made with reference to the block diagram of FIG. 1 as necessary. The still video camera device 10 shown in FIG. 3 has a female modular jack 23 disposed on the side surface 10A of the main body. In the still video camera device, a female modular jack 23 is integrally embedded in the housing by insert processing and protrudes from the side surface 10A. The two female modular jacks 23 shown connect to male modular jacks 32A, 32B, respectively, provided by an external telephone 30 and a converter 31 that converts the telephone line into a modular jack. Through this connection, video data captured by the still video camera device 10 is transmitted via the telephone line.

Further, as shown in FIG. 4, when the telephone side does not have the above-mentioned modular jack, for example, when transmitting data via the public telephone 35, the receiver 36 of the above-mentioned public telephone is connected to the coupler 37, and Data can also be transmitted from the still video camera device 10 by connecting the coupler 37 to a terminal (not shown) on the side surface 10B of the still video camera device 10.

Furthermore, as shown in FIG. 5, a digital public telephone 38 compatible with ISDN (Integrated Service Digital Network)
When transmitting data via, for example, a cable stored in a recess with a lid (not shown) formed in the female modular jack 38A of the digital public telephone 38 and the side surface 10B of the still video camera device. 39 and engages and connects it with the male modular jack 38B disposed at the tip of the cable. By connecting in this way, the still video camera device 10
Data can be sent electronically from

[0021] It is also possible to control a switch so that the operation of the power transmission block 22 is turned on when the cable is pulled out from the main body of the still video camera apparatus. Also, during this data transmission, the still video camera device 1
0 can transmit data while checking the data to be transmitted through the electronic viewfinder 24. In addition, the still video camera device 10 can output data to a liquid crystal monitor, a video camera recorder, etc. via an output terminal, and transmit data electronically.

Furthermore, the still video camera device can not only directly record on a disc via the external output terminal, but also output to a video tape recorder or printer via the external output terminal.

FIG. 6 shows a mechanism for connecting the still video camera device to the main body side using a modular jack.
The explanation will be made with reference to FIG. 3 as necessary. FIG. 6 shows the positional relationship of the microswitch 52 on the cable side and the still video camera side, which have a male modular jack 51 via a female modular jack 50.

As explained above with reference to FIG. 3, the female modular jack 23 is integrally embedded in the side surface 10A of the still video camera device by insert processing into the housing, and only the terminal portion 53 is inserted into the side surface 10A. It's on 10A. A microswitch 52 is provided inside the housing. The microswitch 52 includes, for example, a connection terminal portion 54 and a main body 55. The free end 54A side of the connection terminal portion 54 is shaped to bulge toward the female modular jack 50 side. The free end 54A side is disposed at the opening 56 inside the female modular jack 50. A male modular jack 51 is inserted into a female modular jack 50 from the outside and engaged internally.

At this time, the male modular jack 51
Due to this engagement, the tip portion 57 projects from the opening 56 of the female modular jack 50 and presses the free end 54A of the connection terminal portion 54 of the microswitch. The microswitch 52 has a spring (not shown) that biases in a direction opposite to the pressing direction. This press causes the microswitch 52 to be electrically turned on, for example. Further, when the male modular jack 51 is unplugged, the microswitch 52 is turned off by the bias of a spring installed inside the switch, and is electrically turned off, for example.

With such a mechanism, the still video camera apparatus does not need to perform data transmission processing when data transmission is not performed, that is, when the male modular jack 51 is not inserted and engaged. Taking this into consideration, power consumption is reduced by the operation of the microswitch 52 described above. With this configuration, high-quality still images can be transmitted as data in real time. Furthermore, this still video camera device is capable of various connections depending on the telephone line and telephone model used for data transmission, and is therefore very convenient when transmitting data to urgent media.

Next, a method of separating the still picture transmitter as a transmitter adapter and integrating it with the still video camera device will be described with reference to the exploded perspective view shown in FIG. The battery 60 is connected to the still video camera device main body 10 at once.
The battery 60 supplies power to the still video camera main body 10, and the video signal obtained from the still video camera main body is transmitted to the mounting portion of the still video camera main body 10 to which the battery 60 is attached. A power transmission adapter 70 for transmitting power to the outside via a telephone line is provided.

Specifically, the above-mentioned engagement arrangement is performed using a recess 10D formed in the bottom surface 10C of the still video camera device main body 10.
The mark 61 on the surface of the battery 60 is the installation guide 1.
It is arranged so as to face the 17C and 117D sides. In the electrical transmission adapter 70, the joint surface 71 with the battery 60 has the same shape as that of a battery with good shape and ease of use, such as NP-55 or NP-77 manufactured by Sony Corporation.

In this way, the still video camera device main body 1
By making the bonding area of the 0 batteries the same and using them in common, there is no need to newly secure a space for bonding when installing the power transmission adapter 70. Further, the structure of the electrical transmission adapter 70 can be simplified and engaged and arranged.

Electrodes 72, 73 and battery power lock installation guides 74A to 74D are provided on the joint surface 71 side of the power transmission adapter 70 as contacts for the battery power supply. These two electrode contacts 72 and 73 are elastically supported. Therefore, the protruding electrodes 72 and 73 that are pressed when the battery 60 is attached are housed within the power transmission adapter 70 and form a flat joint surface 71 of the power transmission adapter 70. Further, the battery power lock installation guides 74A to 74D have L-shaped claws protruding from the joint surface 71 of the power transmission adapter 70.

Next, this battery 60 is slid toward the lens 121 of the still video camera device 10. By this sliding, a recess (not shown) formed in the joint surface 62 of the battery 60 engages and integrates the battery power lock installation guides 74A to 74D. Further, in this integrated state, the elastically supported electrodes 72 and 73 are positioned opposite to the electrode surface (not shown) of the recess formed in the joint surface 62 of the battery. When the pressure is removed, the electrodes 72 and 73 are biased toward the joint surface 62 by a spring installed inside the power transmission adapter 70.
It is bonded to the electrode surface of the recess formed in.

Further, in the recess 10D, electrodes 110 and 111 are provided as contacts for the battery power source, and a contact 112 for signal transmission is provided.
and electrical transmission adapter lock installation guide 117A~1
17D is installed. The signal transmission contact 112 consists of five contacts 112A to 112E. The electrodes 110 and 111 as contacts of the battery power supply and the contact 112 for signal transmission are elastically supported as described above. Therefore, the protruding electrode that is pressed when the power transmission adapter 70 is attached is housed within the still video camera device 10, and the bottom surface of the recess 10D becomes flat. The signal transmission contact 112 is a contact for outputting a video signal obtained from the still video camera device body 10 to the outside via a telephone line.

[0033] Furthermore, the electrical transmission adapter lock installation guides 117A to 117D are arranged in a direction L from the bottom of the recess 10D.
It protrudes in the shape of a claw. Next, this electrical transmission adapter 70 is slid in the direction of the lens 121 of the still video camera device 10. By this sliding, a recess (not shown) formed on the joint surface 71' of the electrical transmission adapter 70 engages with and integrates the electrical transmission adapter lock installation guides 117A to 117D. In addition, in this integrated position, the elastically supported electrodes 110 and 111 and the signal transmission contact 112 are in a position facing a recess (not shown) in which the electrode surface of the electrical transmission adapter 70 is disposed. It is joined to the electrode surface of the concave portion formed in the joining surface 71' by the biasing force of a spring installed in the still video camera apparatus main body 10.

In this way, the still video camera device 1
The battery 60 and the power transmission adapter 70 are integrated into the recess 10D formed in the bottom surface 10C of the camera 0, thereby reducing the size of the still video camera device 10 and transmitting data. The power transmission adapter 60 is attached to a side surface 70A, which is one side of the housing of the still video camera device, for example, to a telephone 3 shown in FIG.
Male modular jack 32 on the 0 side and the telephone line 31 side
Female modular jacks 75 and 76 are provided to engage with the connectors A and 32B.

Further, how to use the power switch of the power transmission adapter 70 will be explained with reference to FIGS. 8 to 10. As mentioned above, the electrical transmission adapter 7 shown in FIGS. 8 to 10
0 is a still video camera device main body 10 and a battery 60
It has an integrated structure sandwiched between the two. The switch 77 in the power transmission adapter 70 shown in FIG.
It is arranged between the input battery electrode contact 72 and the output battery electrode 79 in the power transmission adapter from the electrode surface 63 of the power transmission adapter, and is used as the main power switch of this still video camera apparatus. This output battery electrode contact 79 is in contact with the battery electrode contact 110 of the still video camera device. The other electrode surface 64 of the battery 60 is connected to a battery electrode contact 111 of the still video camera device via an input battery electrode contact 73 and an output battery electrode contact 80.

When the switch 77 is turned on, power is supplied from the battery 60 to the still video camera apparatus main body 10 via the power transmission adapter 70. In response to this power supply, the still video camera device main body 10 turns on/off the power using a switch 123 provided in the camera internal circuit 120. The still video camera device main body 10 also includes a decoder (not shown),
It has a Y/C separation circuit and an external input/output terminal, such as a female modular jack. Although this configuration increases the size of the still video camera device itself, it allows input/output to and from the outside without the need for the electrical transmission adapter 70.

Next, the switch 77 in the power transmission adapter 70 shown in FIG. 9 is arranged in parallel to the power line to the still video camera apparatus main body 10 when integrated to supply power. Further, the adapter internal circuit 78 built in the above-mentioned power transmission adapter 70 has a circuit configuration consisting of a decoder, a Y/C separation circuit, an external input/output terminal, etc. built in the still video camera device main body 10 shown in FIG. It has the same circuit. In this way, the switches 123 of the still video camera device main body 10 and the power transmission adapter 70,
77 is independent, so if data transmission is not necessary, turn off the switch 77 on the transmission adapter 70 side.
Power consumption can be reduced, and the still video camera device 10 can perform input/output with the outside at a low cost by simply adding an input/output terminal to the outside without the above-mentioned internal adapter circuit 78 for electrical transmission. can.

Further, in the block diagram shown in FIG. 10, the power transmission adapter 70 does not include a switch, but a switch 123 that is provided in the still video camera device main body 10.
It also serves as a switch for the electrical transmission adapter. In order to use this method, power is supplied from one end of the in-camera circuit 120 to the in-adapter circuit 78 by connecting it to the electrode contact 82 of the power transmission adapter 70 via the electrode contact 118. In addition, the power line from the adapter internal circuit 78 is connected to the power contacts 73 and 8.
It is connected to the power line between 0 and 0.

With such wiring, the electrical transmission adapter 7
Since there is no need for a switch space within the power transmission adapter 70, the power transmission adapter 70 can be made smaller. The internal adapter circuit 78 built into this power transmission adapter 70 has the same circuit configuration as the decoder, Y/C separation circuit, external input/output terminal, etc. built into the still video camera device body 10 shown in FIG. It has a circuit.

Furthermore, when there is no need for data transmission, the still video camera device 10 can be connected to the outside at low cost by simply adding an input/output terminal to the outside without the above-mentioned internal adapter circuit 78 for transmission as described above. Input and output can be performed, and systemization is also possible. Like the power transmission adapter shown in FIGS. 9 and 10, the power transmission adapter 70 has a built-in decoder, Y/C separation circuit, external input/output terminal, etc. in the adapter circuit 78, so the still video camera device main body 10 , can be made the most compact.

Next, a case will be described in which a recess is formed by increasing the contact area of the power transmission adapter provided on the bottom surface of the still video camera device. The need to increase the contact area when engaging and disposing the electrical transmission adapter 70 is due to the fact that the circuit scale within the electrical transmission adapter 70 includes, for example, a decoder, a Y/C separation circuit, an external input/output terminal, etc. from,
It will become quite large. Therefore, it is conceivable that the circuit in the power transmission adapter 70 may be integrated into an IC so as to be housed within the power transmission adapter 70 without increasing the thickness of the power transmission adapter 70, but this is not preferable since it would lead to an increase in cost.

[0042] Therefore, the connection point of the conventional battery 60,
In other words, the battery electrodes 110, 111 and the battery mounting guides 117A to 117D are made to match each other without newly providing them individually, and the contact area of the recess 10D of the still video camera device main body 10 is expanded to accommodate different areas. There is.

This specific configuration will be explained below with reference to FIGS. 11 and 12, and FIG. 7 as necessary. The recess 10D of the still video camera device 10 is formed larger than the contact area of the battery 60 described above. At this time, the battery 60 is pressed to the connection position shown in FIG.
In order to fix it with the battery installation guides 117A to 117D while storing it in alignment with the lens 121, it is slid in the direction of the lens 121 and installed.

However, since the area of the formed recess 10D is larger than the contact area of the battery 60, it is not possible to cover the entire formed recess 10D even when the battery 60 is attached. It becomes impossible to cover it. Among the signal transmission contacts 112, the contacts that cannot be protected are housed and protected by attaching a contact cover 63 to press the contacts that cannot be protected. The contact cover 63 is provided with four mounting guides in the same manner as the battery 60 and is mounted in the same manner. The locking mechanism of this contact cover 63 is locked using attachment guides 119A to 119D as in the case of the battery 60.

As described above, even if the area of the recess 10D formed on the bottom surface of the still video camera device 10 is made large, the contact for signal transmission that cannot be completely covered can be protected by using the contact cover 63.

In addition, the input/output terminals and attachment of the power transmission adapter 70 will be explained with reference to FIG. 12 and FIG. 3 as necessary. The electrical transmission adapter 70 has, for example, female modular jacks 75 and 76 on a side surface 70A, which is one side of the housing, for engaging and connecting from the telephone 30 side and the telephone line 31 side, as shown in FIG. In addition, for example, a switch section 84 consisting of a plurality of selection switches, a liquid crystal display 83 for displaying the status of the still video camera device, etc. are disposed at functional positions.

The battery 60 is attached to the joint surface 71 of the power transmission adapter 70 shown in FIG. 12 to supply power to the power transmission adapter 70.
and is supplied to the still video camera device main body 10. Further, the power transmission adapter 70 is integrated with the still video camera device 10 by being sandwiched between the battery 60 and the recess 10D of the still video camera device main body 10. The procedure for attaching the electrical transmission adapter 70 can be performed in the same manner as the procedure for attaching the battery 60.

[0048] In this recessed portion 10D, eight mounting guides are provided. That is, they are installation guides 117A to 117D and 119A to 119D for installing the battery 60 and the above-mentioned contact cover 63. There is a recess 10D in each of the eight installation guides.
Installation guides 117A, 117B, 1 at four locations around the
Attach using 19C and 119D. At this time, attach the four installation guides 117C, 117D, 119 near the center.
A and 119B are simply formed with slits 124 at corresponding positions on the surface 71' of the electrical transmission adapter 70 facing the still video camera device 10, and are not involved in attachment.

[0049] In order to increase the installation strength, the electrical transmission adapter 70 may use all eight installation guides. Electrical transmission adapter 70 with increased contact area in this way
can be attached to the bottom of the still video camera device 10. The electrical transmission adapter 70 has various connection terminals, a plurality of selection switches, a display section for displaying the status of the device, and the like arranged at functional positions on one side of the casing.

As described above, the power transmission adapter 70 has a large contact area in the recess 10D formed on the bottom surface of the still video camera device 10, so that the decoder in the adapter circuit 78, the Y/C separation circuit, and the external It becomes possible to include not only a circuit configuration consisting of input/output terminals, etc., but also the various switches described above, a driving circuit for the liquid crystal display 83, and the like. Further, as described above, the thickness of the electrical transmission adapter 70 can be made to a practical thickness without the need to stack printed circuit boards in multiple stages by widening the contact area of the recess 10D formed on the bottom surface of the still video camera device 10. Can be done.

[0051]

[Effects of the Invention] As is clear from the above description, according to the still video camera device of the present invention, the power transmission adapter is sandwiched between the battery and the main body of the still video camera device with the same shape as the battery joint. By aligning the respective connection points and engaging and arranging them, space can be secured and a simplified structure can be achieved without providing a new connection area for the electrical transmission adapter. As a result, it is possible to create a switchable video camera device that is a small and lightweight camera with good mobility and operability. Furthermore, depending on the need for the above-mentioned power transmission adapter, only a battery can be attached, and the camera can be used as a smaller camera.

[0052] Furthermore, by providing a wide contact area for housing the power transmission adapter while maintaining the same connection points as described above, and dealing with a large scale power transmission circuit, expensive dedicated ICs can be used.
The electrical transmission circuit can be placed on a single printed circuit board without having to divide the printed circuit board, divide the printed circuit board, or arrange the printed circuit board in multiple stages. At this time, more contacts for signal transmission can be provided.

[0053] Even in data transmission, displays, switches, etc. necessary for data transmission can be functionally arranged in the transmission adapter, thereby improving the functionality of the device.
