  The present invention relates to an improvement in a USB mouse that is point-driven by feeding from a USB standard power supply bus, and in particular, a heating mouse that heats a mouse case by driving an electric heating element using power supplied from the power supply bus. .

  When performing computer input operations using a mouse in a room with low winter temperature or in a summer-cooled room, the body temperature is deprived from the palm and finger of the operator holding the mouse, especially when the fingertip cools down, For example, there is a problem that the “click” operation is typically difficult. On the other hand, it has been proposed to deal with this by putting a cloth cover on the mouse or by wearing an operator's gloves. It is only a measure to suppress heat dissipation to the fingertips, and not only can the problem of cooling the fingertips be completely eliminated, but rather the operability of clicking etc. will be lowered, and it is unsatisfactory as a countermeasure for cooling the fingertips mentioned above. It was something.

  Recently, by connecting to a computer via a USB connector connected to one end of a USB (Universal Serial Bus) standard cable, it is housed in the case of a computer input operation mouse from the computer power supply via a USB power supply bus terminal. In the USB mouse that can be driven by supplying power to the pointing circuit, there is a heating type mouse that heats the mouse case by installing an electric heating element that supplies power from the USB power supply terminal inside the mouse (Patent Document 1 and Non-patent document 1).

However, there is a problem in that the electrothermal material is not arranged in close contact with the inner surface region of the mouse case, the thermal efficiency is poor, the temperature distribution varies, and the power consumption increases.
In addition, since the electrothermal material such as a film heater is placed only on the palm of the hand when the mouse is held, the click pushbutton cannot be heated.
Furthermore, there has been a problem that the mouse is enlarged in order to secure a space for providing an electrothermal material such as a film heater or a nichrome wire.
