Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic device that is electrically connected to an external device by an adapter.

[Conventional technology]

Recently, electronic still cameras have become popular, but with the recent increase in the capacity of solid-state memory, electronic cameras with built-in solid-state memory that are more reliable, durable, smaller, and lighter than electronic still cameras are becoming popular. It is being realized.

This electronic camera with a built-in solid-state memory has a built-in solid-state memory such as a semiconductor memory in a non-removable manner.
The solid-state memory 1 stores image signals obtained by an electronic imaging means such as a CD-type solid-state imaging device.

By the way, in such an electronic camera, once image signals corresponding to the storage capacity of the solid-state memory are stored, the next photograph cannot be taken, so the image signals stored in the solid-state memory must be erased. At this time, if the image signal already stored in the solid-state memory needs to be saved,
Transfer the image signal to another recording medium (external recording medium)
need to be memorized.

Therefore, there is an information recording device for recording image signals stored in a solid-state memory built into an electronic camera on a recording medium with a relatively large storage capacity, such as a floppy disk or a semiconductor memory, which is different from the solid-state memory described above. . This information recording device is connected to the above-mentioned electronic camera, receives image signals stored in the solid-state memory of the connected electronic camera, and records them on a predetermined recording medium.

Furthermore, even if an electronic camera has a removable information recording medium such as a floppy disk or an IC card, the information recorded on the information recording medium can be read when the information recording medium is attached to the electronic camera. The information may be read out to the outside of the electronic camera, and the read information may be recorded on another information recording medium loaded in the information recording device or reproduced on an information reproducing device.

As described above, when information recorded on an information recording medium provided in an electronic camera is read out to the outside of the camera for recording or playback, information is read from the information recording medium provided in the electronic camera. Connection between an information recording device or an information reproducing device including an information reading device and an electronic camera is performed using a connection cord, but conventionally, this connection cord was generally connected to the electronic camera using a plug. This is done by a connector consisting of a jack.

That is, a plug is provided at one end of the connection cord, and the connection cord is connected to the electronic camera by inserting the plug into a jack provided on the electronic camera side.

[Problem to be solved by the invention]

In conventional electronic camera systems such as those mentioned above, the jack for connecting the connection cord is sunk into the electronic camera, but this jack is usually provided in an exposed state. . Here, electronic cameras are often taken outdoors for use, and if the jack is exposed to the outside as described above, there is a risk that the connector will be damaged or corroded by rain or the like. Moreover, noise from the outside tends to enter.

Therefore, it is conceivable to cover the jack part with a cover that can be opened and closed to prevent the above-mentioned problems, but since the lid that can be opened and closed has a complicated structure, it is not very preferable in terms of cost and the like.

Further, Japanese Patent Application Laid-Open No. 114053/1983 discloses an electronic device that has a signal terminal for connection to an external device in a battery storage chamber and is connected to the external device via this signal terminal. . With this electronic device, the signal terminals are not exposed to the outside of the device, making it possible to protect the signal terminals and prevent noise from entering the signal terminals.

However, in the electronic device disclosed in the above-mentioned Japanese Patent Laid-Open No. 63-114053, the signal terminal and the circuit that performs signal processing etc. must be electrically connected with a lead wire or the like. When connecting a signal terminal and a circuit that performs signal processing, etc. using a lead wire, etc., the lead wire is fixed to both the signal terminal and the circuit, for example by soldering. The present invention was made in consideration of these circumstances, and the purpose of the present invention is to protect the connector part while having a simple structure. It is an object of the present invention to provide an electronic device that can minimize noise contamination and signal attenuation.

[Means to solve the problem]

In the first invention of the present application, a terminal for connecting an adapter is formed directly on the circuit board of the electronic device, and this terminal is exposed to the battery mounting portion.

In addition, in the second invention of the present application, a terminal for connecting an adapter is formed directly on the circuit board of the electronic device, and this terminal is exposed to a battery mounting part, and when a battery is mounted to the battery mounting part, The external shape of the adapter is substantially the same as the external shape when the adapter is attached to the battery mounting part.

In a third invention of the present application, in the electronic device according to the first or second invention, the battery connection terminal and the adapter connection terminal are arranged at different heights.

[Effect]

By taking such measures, the following effects are achieved. That is, by forming the adapter terminal directly on the circuit board, there is no need to use a lead wire or the like to connect the adapter connection terminal and the circuit board, and the number of parts that cause noise intrusion and signal attenuation is reduced.

It becomes possible to read out the image signals stored in the . Further, the electronic camera 10 is driven by electric power obtained from a commercial power source.

As described above, according to this embodiment, the connector pattern 65 serves as a connection terminal for connecting the information recording/reproducing device 20.
However, it is covered by the battery 15 when photographing or the like, that is, during normal times.

Therefore, the connector pattern 65 can be reliably protected without providing a new cover or the like to cover the connector pattern 65.

In addition, the contact pieces 41a, 41b and the information input terminal 56 have a step difference due to the convex portion 55, so that the battery 1
5 or the connecting head 21 to the battery mounting part 30, the contact pieces 41a, 41b do not come into contact with the connector pattern 65, which may cause unnecessary wear of the connector pattern 65 or cause excessive current to flow in the circuit. It is possible to prevent the elements from being destroyed by Furthermore, when the electronic camera 10 is connected to the information recording/reproducing device 20, it does not have to be portable, so it does not need to be battery-powered, and it is preferable that it be operated by power from a commercial power source. , if this electronic camera 10 is used, it can be used as a commercial electric camera 11iX118 by simply attaching the connecting head 21.
It is convenient because there is no need to obtain power from a separate power cord or the like. Furthermore, since all the circuits are mounted on one board, the device can be made smaller. Further, since the heavy battery 15 is provided in the grip, the weight balance is good and stability is improved during photographing and the like.
