BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless telephone device that charges and uses a storage battery housed in a handset.

2. Description of the Related Art FIG. 4 shows the configuration of a conventional cordless telephone device in which a handset is placed face down and placed on a charging stand for charging. In FIG. 4, reference numeral 4 denotes a handset, which houses a rechargeable storage battery and a transmission / reception circuit for making a wireless call with a telephone body connected to a telephone line. Reference numeral 4a denotes a power supply terminal surface, on which power supply terminals 41 and 42 are arranged at regular intervals. 4b is a push button surface on which the push button 6 is arranged. 4c is a mouthpiece surface, and a mouthpiece 7 is provided. Reference numeral 8 is an earpiece, and 9 is a wireless communication antenna. 3 is an AC adapter for converting a commercial AC power supply voltage into a DC voltage. Reference numeral 5 is a charging stand that houses a charging circuit. 5a
Is a charging terminal surface, 5b is a handset mounting guide, 5c is a charging base upper surface, and 5d is a charging base slope. 51 and 52 are power terminals 41 and 42
The charging terminals are arranged on the charging terminal surface 5a with an interval equal to the interval therebetween.

Next, the operation of the above conventional example will be described. The handset 4 is placed on the charging stand 5 such that the power supply terminal surface 4a and the charging terminal surface 5a, the push button surface 4b and the charging stand upper surface 5c, the mouthpiece surface 4c and the charging stand slope 5d face each other. When the power supply terminals 41, 42 and the charging terminals 51, 52 are in contact with each other, it is assumed that the condition as shown in FIG. The handset 4 is charged from 5.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in this type of telephone device, when the handset 4 is placed on the charging stand 5 in a state as shown in FIG. There is a problem that charging is not performed because the charging terminals 51 and 52 are not in contact with the charging terminals 41 and 42.

The present invention solves such conventional problems,
An object of the present invention is to provide an excellent cordless telephone device that prevents a contact failure between a power supply terminal and a charging terminal due to how the handset is placed by allowing the handset to be normally placed on a charging stand.

Means for Solving the Problems In order to achieve the above object, the present invention provides a handset with a positioning protrusion provided on both sides of the handset, and a charging base with guide recesses for engaging the handset. When it is placed on, the positioning projection of the handset is guided and engaged with the guiding recess provided in the charging stand so that the power supply terminal and the charging terminal can come into contact with each other.

Therefore, according to the present invention, when the handset is placed on the charging stand, the handset and the charging stand are provided with the engaging portions, so that the charging terminal and the power supply terminal can be surely brought into contact with each other for stable use. Has the effect.

Embodiment FIG. 1 shows the structure of an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a handset, which houses a rechargeable storage battery and a transmission / reception circuit for performing wireless communication with a telephone body connected to a telephone line. Reference numeral 1a is a power supply terminal surface, and power supply terminals 11 and 12 are arranged on this surface at regular intervals. 1b is a push button surface, on which the push button 6 is arranged. 1c is a mouthpiece surface, and a mouthpiece 7 is provided. Numerals 13 and 14 are positioning protrusions provided on the two sides of the handset 1, respectively.
It has the shape of a triangular prism. Reference numeral 8 is an earpiece, and 9 is a wireless communication antenna. 3 is an AC adapter for converting a commercial AC power supply voltage into a DC voltage. 2 is a charging stand that houses a charging circuit. 2a is a charging terminal surface, 2b is a handset mounting guide, 2c is a charging base upper surface, and 2d is a charging base inclined surface. 21 and 22 are charging terminals, and these charging terminals 21 and 22 are power terminals 11 and 12.
With a space equal to the space between the handset 1 and the charging stand 2, the power supply terminal surface 1a and the charging terminal surface 2a, the push button surface 1b and the charging stand upper surface 2c, the mouthpiece surface 1c and the charging stand slope 2d. Power terminals 11 and 12 when they are placed facing each other.
It is provided at the position where it respectively contacts with. Reference numerals 23 and 24 denote guiding recesses provided in the handset mounting guide 2b,
In the above-mentioned installed state, the positioning protrusions 13 and 14 are guided and engaged with each other, and are provided at the engaging positions.

Next, the operation of the above embodiment will be described. In the above embodiment, when in the above-mentioned installed state, that is, the power supply terminal surface 1a
And charging terminal surface 2a, push button surface 1b and charging stand top surface 2c,
The mouthpiece surface 1c and the charging base slope 2d face each other, and the positioning protrusions 13 and 14 and the guiding recesses 23 and 24 are engaged with each other. This state is a normal placement state. At this time, the power supply terminals 11 and 12 and the charging terminals 21 and 22 are brought into contact with each other, so that the charging stand 2 is charged into the handset 1. FIG. 2 is a schematic sectional view at this time.

Further, as shown in FIG. 3, when the handset 1 is tilted with respect to the charging stand 2, the positioning protrusions 13 and 14 are guided to the guiding recesses 23 and 24, and the handset 1 is indicated by an arrow. In the normal mounting state shown in FIG. 2, the charging stand 2 is charged into the handset 1.

Thus, according to the above embodiment, the handset 1 is connected to the charging stand 2
Since the positioning projections 13 and 14 are guided to the guiding recesses 23 and 24 even when placed in a tilted manner, the above-described placement state is obtained.
It has the advantage of being charged.

Although the positioning protrusions 13 and 14 are triangular prisms in the above embodiment, they may be hemispherical. In this case, the degree of freedom in the initial placement for the handset 1 to be normally placed on the charging stand 2 is increased.

EFFECTS OF THE INVENTION As is apparent from the above-described embodiment, the present invention has positioning protrusions provided on both sides of the handset, and is provided as a pair in the handset placement guide of the charging stand, and the handset is placed on the charging stand. When
Since the positioning projection is guided and has a guiding recess for engaging, even when the handset is tilted and placed on the charging stand,
Since the charging terminal and the power supply terminal can be surely contacted with each other and the positioning projection is projected to the outside of the housing, positioning can be easily performed when the positioning projection is engaged with the guiding recess. It has the effect that
