Abstract

PURPOSE:To improve the operability by forming a portion of an AC adapter such that it can be inserted into the battery containing section of an electronic machinery. CONSTITUTION:When it is used as an AC adapter, the joint section 22 is rotated in the direction of an arrow A around a pivot pin 20 and locked then it is inserted into the battery containing section of an electronic still camera. Consequently, the terminal 24 at the joint 22 is connected with the battery terminal of the electronic still camera 30, and when a plug 28 is inserted into an AC source receptacle voltage can be applied onto the electronic still camera. When the AC power adapter 10 is used as a battery charger, the mount/dismount section 22 is taken out from the electronic still camera 30 and the AC power adapter 10 is unlocked, then the mount/dismount section 22 is rotated in the direction of an arrow B around the pivot pin 20 and contained in the lower stage 16 at an exposed section 12. Then a battery is inserted into a receiving port 14A and recharged.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an AC power adapter, and particularly to an AC power adapter used in electronic equipment using a battery.

[Conventional technology]

When using a VTR etc. outdoors, a battery is used as the power source, but when using a VTR etc. indoors, AC Ml! is used instead of the battery. An AC power adapter connected to H may be used. This AC power adapter is
It is formed in the same shape as a battery used as a power source for a TR, etc., and is attached to a battery storage section.

However, with the miniaturization of devices that use batteries, such as electronic still cameras, the batteries have become smaller, so it has become difficult to miniaturize the AC power adapter into the same shape as the batch r.

In order to solve this problem, a separate type AC power adapter has been devised. In this type, a power coupler having the same shape as the battery is connected to the AC power adapter via a cable. Therefore, it is possible to attach the buff coupler to an electronic still camera and connect the AC power adapter to an alternating current power source to apply voltage to the camera body.

[Problem that the invention seeks to solve]

However, this type has a problem that the electronic still camera has poor operability because the AC power adapter and power coupler are separated.

Additionally, there may be a problem that the cable may break during transportation.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide an AC power adapter with improved operability and whose cable does not break during transportation.

[Means for solving problems]

In order to achieve the above object, the present invention provides an AC power adapter for applying voltage to an electronic device using a battery, in which a part of the AC power adapter is configured in a shape that can be inserted into a battery storage section of the electronic device. It is characterized by:

[Function] According to the present invention, a part of the AC power adapter is configured in a shape that can be inserted into the battery compartment of an electronic device, thereby improving the operability of the device and preventing cable breakage during transportation. I can do it.

〔Example〕

Preferred embodiments of the AC power adapter according to the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, the AC power adapter 10 has an exposed portion 12, and the exposed portion 12 includes an upper stage I4 and a lower stage 16.
is formed. There is a battery receiving port 1 in the upper stage 14.
4AS14A is formed, and a terminal (not shown) is disposed within the receiving port 14A. This receiving port 14A is formed so as to be able to accommodate a battery (not shown).
When the battery is stored, the battery terminal and inlet 14A
The terminals inside are electrically connected.

Further, in a plane 18 perpendicular to the upper stage 14 and the lower stage 16,
The end of the pivot pin 22 is fixed.

The lower end of the connecting portion 22 is rotatably supported by the pivot pin 22 . The lower end surface of the connecting portion 22 is connected to the pivot pin 20
It is formed in a semi-circular arc shape centered on the axis of. Also,
Terminals 24.24 are arranged at the upper end of the connecting portion 22. In addition, in FIG. 1, 26 is a cable and 28 is a connector.

The operation of the AC power adapter according to the present invention configured as described above will be explained.

First, the case where it is used as an AC power adapter will be described. The connecting portion 22 is rotated in the direction of the arrow with the pivot pin 20 as a fulcrum and locked at the position shown in FIG. Insert the locked connection part 22 into the battery compartment of the electronic still camera. At this time, the terminals 24, 24 of the connection part 22,
A terminal (not shown) for the battery of the electronic still camera 30 is connected. Therefore, when the outlet 28 is inserted into an outlet (not shown) of an AC power source, voltage can be applied to the electronic still camera 30.

Next, a case will be described in which the AC power adapter 10 is used as a battery charger. The removable part 22 is taken out from the battery removable part of the electronic still camera 30, the lock is released, the removable part 22 is rotated in the direction of arrow B about the pivot pin 20, and is stored in the lower stage 16 of the exposed part 12. After storing, insert the battery (not shown) into the receiving port 14A, 1.
When inserted into 4A, the terminals of the battery and the terminals of the receiving port are connected, so the battery is charged.

In the above embodiment, an AC adapter for an electronic still camera in which the battery is stored from the bottom of the camera body has been described, but the invention is not limited to this, but an electronic still camera in which the battery is stored from the side of the camera body as shown in FIG. May be used for 50. In FIG. 2, 52 is an AC power adapter, 54 is a cable, 56 is a connector, and 58 is a terminal.

Further, the AC power adapter according to the present invention may be used not only for electronic still cameras but also for other battery-powered devices.

〔Effect of the invention〕

As explained above, according to the AC power adapter according to the present invention, a part of the AC power adapter is configured in a shape that can be inserted into the battery compartment of an electronic device, so that the operability of the device is improved. , it is possible to prevent cable wires during transportation.
