And the main part is comprised by the front-end | tip part comprised by 14 A of 1st fork parts and the 2nd fork part 14B which were extended in the fork shape from the front end of this trunk | drum 14E. The base end portion 14C, the lead wire mounting portion 14D, the body portion 14E, the first fork portion 14A, and the second fork portion 14B are formed from a single elastic plate that is a spring material.
[0020]
A first contact portion 14a curved in an arc shape is formed at the tip of the first fork portion 14A so as to contact the electrode 24a formed on one outer surface 25a of the battery 25. A second contact portion 14b curved in an arc shape is formed at the tip of the second fork portion 14B so as to contact the electrode 24b formed on the other outer surface 25b of the battery 25.
[0021]
The first fork 14A branches from one end of the body part 14E in order to urge the battery 25 in the insertion / extraction direction of the battery 25, and forms a part of a dogleg with a large degree of bending together with the body part 14E. The second fork portion 14B is branched from the one end of the trunk portion 14E in order to urge the battery 25 in a direction substantially perpendicular to the insertion / extraction direction of the battery 25, and is bent with a small degree of bending together with the trunk portion 14E.

FIGS. 3 and 4 show a state in which the battery 25 is inserted and the battery lid 11 is closed in the battery housing chamber 10 in which the contact piece 14 formed in this manner is fixed to the ceiling surface 10B with screws 19. . The first contact portion 14a of the contact piece 14 contacts the electrode 24a of the battery 25 and urges the battery 25 in the battery discharge direction α ′ in the battery insertion / removal direction.
[0023]
Conventionally, as shown in FIG. 5, when the battery 250 is brought into contact with the electrical contact piece 120 and accommodated in the battery accommodating chamber 100, the pressing spring 140 disposed on the ceiling surface of the battery accommodating chamber 100 Although the upper surface of the battery 250 is urged in the battery discharge direction of the battery insertion / removal direction, in the present embodiment, the contact piece 14 also serves as a pressure spring, and therefore it is not necessary to dispose the pressure spring. .
[0024]
When the battery 25 is inserted into the battery housing chamber 10 and the battery lid 11 is closed, the second contact portion 14 b of the contact piece 14 comes into contact with the electrode 24 b of the battery 25. Thereby, as shown in FIG. 4, the electrode 24 of the battery 25 is in contact with the contact portions (14a, 14b) of the contact piece 14 by the electrodes (24a, 24b) on the two surfaces.
[0025]
In this way, when the electrode 24a of the battery 25 is brought into contact with the first contact portion 14a of the contact piece 14 and the first fork portion 14A is biased toward the insertion side α in the battery insertion / removal direction, the fork of the contact piece 14 is obtained.

[0026]
Accordingly, the force by which the first contact portion 14a of the contact piece 14 urges the battery 25 in the battery discharge direction of the battery insertion / extraction direction is increased, and the second contact portion 14b of the contact piece 14 is increased by the battery 25. Is increased in the direction substantially perpendicular to the battery insertion / removal direction, so that the contact pressure between the first contact portion 14a and the electrode 24a and the second contact portion 14b and the electrode 24b increases. Therefore, the first contact portion 14a prevents chattering from occurring in the battery insertion / removal direction, and the chattering occurrence is second from the vibration in a direction substantially perpendicular to the battery insertion / removal direction. This is prevented by the contact portion 14b.
[0027]

Therefore, for example, even if vibration is generated in the height direction and the lateral direction of the digital camera by, for example, placing the digital camera body roughly on the desk while recording the captured image data on the medium, the battery 25 Is urged by the contact piece 14 in the battery insertion / removal direction and the direction perpendicular to the battery insertion / removal direction, so that even if the contact piece slides on the battery electrode, the contact piece is separated from the electrode. Therefore, the occurrence of chattering due to vibration can be suppressed.
[0029]
Further, since the first contact portion 14a of the contact piece 14 urges the battery 25 in the battery discharge direction of the battery insertion / extraction direction, there is no need to provide a pressing spring in the battery housing chamber 10. Further, since the second contact portion 14b of the contact piece 14 urges the battery 25 in a direction substantially orthogonal to the battery insertion / removal direction, the first contact portion 14a, the electrode 24a, the second contact portion 14b, The contact pressure of the electrode 24b increases, and the battery 25 can be reliably fixed in the battery housing chamber 10.
[0030]

It may be formed on any surface of 25. In this case, the contact piece 14 may be disposed at a position where it can come into contact with the electrode 24 in the battery housing chamber 10 according to the position where the electrode 24 is formed.
[0031]
For the sake of simplicity, three electrodes (a negative electrode 21a, a thermistor electrode 22a, and a positive electrode 23a) formed along a direction substantially perpendicular to the battery insertion / extraction direction of one outer surface 25a are used as the electrode 24a, and the other outer surface 25b. The electrodes (the negative electrode 21b, the thermistor electrode 22b, and the positive electrode 23b) formed along the battery insertion / removal direction are referred to as electrodes 24b. The electrodes 24a and 24b are connected to the first contact piece 14 in the first embodiment. Although the contact portion 14a and the second contact portion 14b are in contact with each other, actually, three contact pieces 14 are arranged in the battery housing chamber 10, and each of the three first contact portions 14a is The three second contact portions 14b are in contact with the negative electrode 21b, the thermistor electrode 22b, and the positive electrode 23b, respectively, in contact with the negative electrode 21a, the thermistor electrode 22a, and the positive electrode 23a.
