Abstract

An electronic apparatus comprises: a displacement unit provided to an electronic apparatus main body; a first power source provided to the main body and supplying power to a load provided to the displacement unit; a first connecting unit that opens and closes a first supply path supplying an electric current from the first power source to the load in response to displacement of the displacement unit; a limiting unit provided on the first supply path and limiting an electric current flowing through the first supply path for a predetermined time from when an electric current is supplied from a second power source; and a second connecting unit that opens and closes a second supply path supplying an electric current from the second power source to the limiting unit in response to the displacement, wherein the first connecting unit opens and closes the second supply path in response to the displacement.

First claim

What is claimed is:

1. An electronic apparatus comprising:
a drawer unit configured to be provided drawable from a main body of the electronic apparatus main body;
a first power source configured to be provided to the main body and supply power to a load provided to the drawer unit;
a first connecting unit configured to open and close a first supply path that supplies an electric current from the first power source to the load in response to displacement of the drawer unit;
a limiting unit configured to be provided on the first supply path and limit an electric current flowing through the first supply path for a predetermined time from when an electric current being to be supplied to the limiting unit is supplied from a second power source different from the first power source; and
a second connecting unit configured to open and close a second supply path that supplies an electric current from the second power source to the limiting unit of an electric current in response to displacement of the drawer unit, wherein
the first connecting unit opens and closes the second supply path in response to displacement of the drawer unit.

2. The electronic apparatus according to claim 1 , wherein
the first connecting unit and the second connecting unit are provided in series on the second supply path.

3. The electronic apparatus according to claim 1 , wherein
the first connecting unit uses a closed loop on the second supply path provided to the drawer unit, thereby closing the second supply path.

4. The electronic apparatus according claim 1 , wherein
the drawer unit is moved parallel or is opened and closed with respect to the electronic apparatus main body.

5. The electronic apparatus according to claim 1 , further comprising an opening and closing unit configured to be arranged on the first path and comes into a closed state when receiving an electric current from the second power source.

6. The electronic apparatus according to claim 1 , wherein
the first connecting unit and the second connecting unit come into a closed state when the drawer unit is housed in the electronic apparatus main body.

7. An image forming apparatus comprising:
a main body of the image forming apparatus;
a displacement unit configured to be provided displaceably with respect to the main body;
a first power source configured to be provided to the main body and supply power to a load provided to the displacement unit;
a first connecting unit configured to open and close a first supply path that supplies an electric current from the first power source to the load in response to displacement of the displacement unit;
a limiting unit configured to be provided on the first supply path and limit an electric current flowing through the first supply path for a predetermined time from when an electric current being to be supplied to the limiting unit is supplied from a second power source different from the first power source; and
a second connecting unit configured to open and close a second supply path that supplies an electric current from the second power source to the limiting unit in response to displacement of the displacement unit, wherein
the first connecting unit opens and closes the second supply path in response to displacement of the displacement unit.
