It is intended to facilitate the opening of the lid that opens and closes the opening of the battery housing concave portion.

(B. Outline of the Invention) In the electronic device of the present invention, a lid that opens and closes the opening of the battery accommodating recess is formed rotatably and slidably on the main body, and the lid is installed from the closed position to the auxiliary electronic device unit. The lock is released by sliding so as to project from the end surface side, and it can be rotated to the open position.
As the lid is slid in the above direction, the slope formed on the auxiliary electronic device unit pushes up the pivot end of the lid so that the lid is slightly rotated toward the open position. Even when the device unit is attached to the main body, the lid body can be easily rotated in the opening direction, which significantly improves the operability.

(C. Prior art) [FIGS. 4 and 5] An electronic device including a main body having a battery storage recess for storing a power supply battery and an auxiliary electronic device unit detachably attached to the main body. As an example, a rechargeable battery and a dry battery can be used together as a power source, and a main body portion having a recess for accommodating the rechargeable battery and a battery case detachably accommodated and detachably attached to the main body portion are provided. There are electronic devices.

For example, such is found in portable stereo cassette players.

4 and 5 show an example a of such a portable stereo cassette player.

Reference numeral b denotes a main body portion, which is not shown, but is provided with a cassette mounting portion for mounting an audio tape cassette, a mechanical deck for reproducing the mounted tape cassette, a reproducing circuit portion, and the like.

Reference numeral c denotes a battery case, in which a dry battery (not shown) is detachably accommodated, and an attaching means (not shown) is attached to one end surface (hereinafter referred to as “battery case attachment end surface”) d of the main body portion b. When the battery is attached to the main body b, the dry battery stored in the main body b serves as a power source for the mechanical deck, the circuit, and the like.

A rechargeable battery accommodating recess e is formed at an end portion of the main body portion b in contact with the battery case attaching end surface d, and the accommodating recess e has an opening g on one side face f adjacent to the battery case attaching end surface d. Have The accommodating recess e accommodates a rechargeable battery such as a nickel-cadmium battery.
It will be the power source for the mechanical deck and circuit section.

Reference numeral h is a lid for opening and closing the opening g of the rechargeable battery storage recess e.

The lid h is rotatably supported by the end of the opening g on the side opposite to the attachment end face d and slidable along the side face f.

Then, the lid h has an opening g as shown in FIG.
Is locked in the closed position where the
Is slid in the direction, and its rotation end i is attached to the battery case attachment end surface d.
The above-mentioned lock is released in the state of being protruded from, and it becomes possible to rotate toward the open position for opening the opening g as shown in FIG. 5 (B).

A notch j is formed in the battery case c at a position facing the rotation end i of the lid h, and when the lid h is opened with the battery case c attached to the main body b, the lid h is opened. Battery case c to unlock by sliding h in the direction of arrow A
Is out of the way.

(D. Problems to be Solved by the Invention) [FIGS. 4 and 5] In the conventional electronic device a described above, a battery is used to slide the lid h to unlock. Although the case c does not get in the way, there is a problem that it is difficult to perform an operation for rotating the unlocked lid h toward the open position.

That is, in order to rotate the lid body h toward the open position, the pivot end i must be hooked with the fingertip k and pulled toward the open position. First, the fingertip k of the lid body h is moved. The cutout j is too small to fit the turning end i, and the operability is extremely poor. However, increasing the size of the cutout j undesirably increases the shape of the battery case c itself and is not preferable for a portable electronic device. Next, even if the fingertip k is applied to the rotating end i, most of the moment of the force applied to the rotating end i closes the lid h when the rotating end i is in the notch j. Since it acts so as to slide it toward the position, the operability is also very poor in this respect.

In order to improve such a drawback, a spring is attached to the lid body h, and when the lock is released, the lid body h is slightly pivoted toward the open position by the spring so that the pivot end i thereof. It is conceivable that the fingertips can be easily hooked on the pivoting end i by making it float, but this is not preferable because the number of parts increases and the structure becomes complicated.

Means for Solving the Problem) In order to solve the above-mentioned problems, the electronic device of the present invention has a lid body for opening and closing the opening of the battery accommodating recess provided in the body portion, which is rotatable on the body portion. The lid is slidably formed, and the lid is slid so as to project from the attachment end surface of the auxiliary electronic device unit so that the lock can be released and the lid can be rotated toward the open position. In addition, as the lid slides in the above direction, the slope formed on the auxiliary electronic device unit pushes up the turning end of the lid, so that the lid is slightly turned toward the open position. It is the one.

Therefore, in the electronic device of the present invention, the lid is unlocked by sliding the lid from the closed position in the direction in which the pivot end projects from the attachment end face of the auxiliary electronic device unit, and subsequently, the lock is released. Since the turning end of the lid is pushed up by the slope of the auxiliary electronic device unit and protrudes from the side surface of the main body and battery case, it is extremely easy to hook it with your fingertip to turn it.
