Slide unit moving device with energy-assisted movement, and image formation apparatus

A slide unit moving device provided between an apparatus main body of an image formation apparatus and a slide unit provided on the apparatus main body to be withdrawable from the apparatus main body, for moving the slide unit with respect to the apparatus main body, comprising:

• a rail on which the slide unit moves between an accommodation position and a withdrawal position;
• a charge elastic member which is charged with energy to interlock with the slide unit moving from the accommodation position to the withdrawal position;
• a lock unit which locks the charge elastic member into a state of being charged with the energy;
• an interlocking release unit which releases interlocking of the charge elastic member with the slide unit with respect to the moving of the slide unit from the withdrawal position to the accommodating position;
• and
• an unlock unit which releases locking of the charge elastic member by the lock unit at a final stage of moving the slide unit from the withdrawal position to the accommodation position,
• wherein the slide unit is moved to the accommodation position by the energy charged in the charge elastic member by releasing locking by the lock unit at the final stage of moving the slide unit.
