Abstract

In accordance with one embodiment, a power supply apparatus includes a movable terminal section configured to be attached on or detached from and electrically connected with a fixed terminal section corresponding to the attaching or detaching of a unit on or from a main body; a sliding section configured to support the movable terminal section and slide; a guide stud which has a positioning section inserted into the guide hole of the sliding section, a shaft section smaller in sectional area than the positioning section and a connection section for connecting the positioning section with the shaft section, configured to guide the sliding section; and an elastic section configured to press the sliding section towards a unit terminal section.

First claim

1 . A power supply apparatus, comprising:
a movable terminal section configured to be attached on or detached from and electrically connected with a fixed terminal section corresponding to the attaching or detaching of a unit on or from a main body; a sliding section configured to support the movable terminal section and slide; a guide stud, which has a positioning section inserted into the a guide hole of the sliding section, a shaft section smaller in sectional area than the positioning section and a connection section for connecting the positioning section with the shaft section, configured to guide the sliding section; and an elastic section configured to press the sliding section towards a unit terminal section.

2 . The power supply apparatus according to claim 1 , wherein
the fixed terminal section is a unit terminal fixed on the unit, the sliding section slides towards or away from the main body, and the guide stud is fixed on the main body.

3 . The power supply apparatus according to claim 2 , wherein
the guide stud fixes the an apical portion at the side of the positioning section on the main body; and the elastic section is a coil spring into which the guide stud is inserted and applies a pressure in a direction of separating the sliding section from the spring stop section at the rear end part of the guide stud.

4 . The power supply apparatus according to claim 1 , further comprising:
a guide plug configured to guide the fixed terminal section and the movable terminal section to an inserting position, wherein when the difference in level on an inclined guide at the front end of the guide plug is F, the diameter of the guide hole is φE, and the diameter of the shaft section is φB, then F, φE , and φB meet the following relationship: φE−φB>F.

5 . An image forming apparatus, comprising:
a main body configured to include an image forming section for forming an image on a recording medium; a movable terminal section configured to be attached on or detached from and electrically connected with a fixed terminal section corresponding to the attaching or detaching of a unit on or from the main body; a sliding section configured to support the movable terminal section and slide; a guide stud, which has a positioning section inserted into the a guide hole of the sliding section, a shaft section smaller in sectional area than the positioning section and a connection section for connecting the positioning section with the shaft section, configured to guide the sliding section; and an elastic section configured to press the sliding section towards a unit terminal section.

6 . The image forming apparatus according to claim 5 , wherein
the fixed terminal section is a unit terminal fixed on the unit, the sliding section slides towards or away from the main body, and the guide stud is fixed on the main body.

7 . The image forming apparatus according to claim 6 , wherein
the guide stud fixes the an apical portion at the side of the positioning section on the main body; and the elastic section is a coil spring into which the guide stud is inserted, and applies a pressure in a direction of separating the sliding section from the spring stop section at the rear end part of the guide stud.

8 . The image forming apparatus according to claim 5 , further comprising:
a guide plug configured to guide the fixed terminal section and the movable terminal section to an inserting position, wherein when the difference in level on an inclined guide at the front end of the guide plug is F, the diameter of the guide hole is φE, and the diameter of the shaft is φB, then F, φE, and φB meet the following relationship: φE−φB>F.

9 . The image forming apparatus according to claim 5 , wherein the unit is a paper feed cassette for storing the recording medium fed to the image forming section.
