Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device including an outer casing having a mechanism for fixing a battery at a predetermined position on a substrate.

[0002]

2. Description of the Related Art Conventionally, for example, an electronic device having a timepiece function uses an output of a small battery such as a button type battery as a power source of the timepiece. In general, a battery lid for disposing and closing the button type battery at a predetermined position on the substrate is provided.

This battery lid is provided with a lock mechanism so that it cannot be opened easily. With this locking mechanism, it is possible to avoid accidental ingestion accidents, such as an infant taking out the button-type battery without permission and swallowing the battery, or an accident in which the watch stops due to the unexpected removal of the battery. Therefore, in the battery lid that covers the battery as described above, a lock mechanism that prevents the battery lid from being opened unexpectedly is indispensable.

Further, for example, when replacing the battery, it is possible to release the lock mechanism and then open the battery cover.

[0005]

By the way, when it becomes necessary to open the battery cover, it is necessary to once release the lock mechanism as described above. Therefore, conventionally, in order to open the battery lid, a two-step operation of releasing the lock mechanism and moving the battery lid was required. Further, there is no way to confirm the operation of the first stage, that is, whether or not the lock mechanism is released.

Further, since the lock mechanism is provided so that the battery lid is not opened inadvertently, the lock mechanism is not easily released. If the user replaces the battery, If the battery lid is to be opened before the lock mechanism is released or before the lock mechanism is completely released, the battery lid and the lock mechanism portion may be damaged.

Therefore, it is possible to solve the above-mentioned problem by providing a confirmation mechanism for confirming whether or not the lock mechanism is in the completely released state. However, in addition to the members constituting the confirmation mechanism being required, a space for arranging these members is also required.

Therefore, the present invention has been made in view of the above-mentioned circumstances, and the lock mechanism of the battery lid is not easily released, and the state of the lock mechanism can be confirmed without additional members. It is an object of the present invention to provide an electronic device having a mechanism for fixing various batteries on a substrate.

[0009]

In order to solve the above-mentioned problems, the present invention provides an electronic apparatus including an outer casing having a mechanism for fixing a battery at a predetermined position on a substrate,
A rotating lid that fixes the battery at a predetermined position on the substrate and that is rotatably supported by the outer casing, and a lock member that is supported by the outer casing so as to be contactable and separable with respect to the rotating lid.
An operating portion for operating the lock member, and an elastic member for elastically biasing the lock member in a direction approaching the rotary lid are provided, and the engaging projection provided on the rotary lid and the lock member are provided. The lock lid is engaged with the lock claw, and the rotation torque required to rotate from the closed position to the open position is larger than the rotation torque required to rotate the rotary lid from the open position to the closed position. It is provided in.

Further, the lock member, the operating portion and the elastic member may be integrally formed.
Further, the lock claw forms a gentle inclination with respect to the rotation locus of the engagement protrusion from the open position to the closed position, and has a steep inclination with respect to the rotation locus from the closed position to the open position. Can be mentioned.

[0011]

According to the present invention, in an electronic device, when a battery, for example, a button type battery is arranged at a predetermined position on the substrate, the rotary lid is fitted into a predetermined position of the outer casing, and rotated toward the closed position. , Because the rotation torque required to rotate the rotary lid from the open position to the open position is larger than the rotation torque required to rotate the rotary lid from the open position to the closed position. No significant force is required to rotate from the open position to the closed position. Further, since the lock member is elastically biased by the elastic member in the approaching direction to the rotary lid, the lock claw is pushed outward by the engaging projection toward the rotary lid, When the rotary lid is rotated to the closed position, the rotary lid returns to the original position, and the lock claw and the engagement protrusion are engaged with each other.

Further, when the rotary lid is in the closed position, the lock claw and the engagement protrusion are engaged with each other. A large force is required to rotate the rotary lid from the closed position to the open position without performing the above operation, and therefore, if the engagement between the lock claw and the engagement protrusion is not released, the rotation is not performed. The lid does not rotate towards the open position.
