is fitted to the connection terminal, wherein one of the external terminal or the connection terminal is configured to be elastically deformable to allow the external terminal and the connection terminal to fit to each other by sandwiching the other one of the external terminal or the connection terminal between the one of the external terminal or the connection terminal, the lever includes an arm including the fulcrum and a first action part, the first action part being located closer to the battery device than the fulcrum in the state where the external terminal of the battery device is fitted to the connection terminal and being configured to contact the battery device when the lever rotates about the fulcrum, and a gripper connected to a side of the arm opposite to the first action part with respect to the fulcrum, and when the lever rotates about the fulcrum by a force applied to the gripper, the first action part applies a force to the battery device such that the battery device slides in a direction in which fitting between the external terminal and the connection terminal is canceled. ### Claim 2 (depends on 1) The battery mounting unit according to claim 1, wherein the lever rotates about the fulcrum to be switched between a fixed state where the battery device is fixed to the apparatus with the external terminal fitted to the connection terminal and an unfixed state where fitting between the external terminal and the connection terminal is canceled. ### Claim 3 (depends on 1) The battery mounting unit according to claim 1, wherein the lever includes a first protrusion serving as the first action part, and the first action part is configured to apply a force to the battery device through a first load receiving surface of the battery device such that the battery device slides in a direction in which fitting between the external terminal and the connection terminal is canceled when the lever rotates about the fulcrum in a first direction by a force applied to the gripper. ### Claim 4 (depends on 1) The battery mounting unit according to claim 1, wherein the lever includes a second protrusion serving as a second action part, and the second action part is configured to apply a force to the battery device through a second load receiving surface of the battery device such that the battery device slides in a direction in which the external terminal is fitted to the connection terminal when the lever rotates about the fulcrum in a second direction by a force applied to the gripper. ### Claim 5 (depends on 4) The battery mounting unit according to claim 4, wherein the first direction in which the external terminal is slidable with respect to the connection terminal is a direction in which the battery device moves away from the apparatus, and the first protrusion is disposed at a location closer to the apparatus than the second protrusion in the lever. ### Claim 6 (depends on 1) The battery mounting unit according to claim 1, wherein the first direction in which the external terminal is slidable with respect to the connection terminal is a direction in which the battery device moves away from the apparatus, the first action part is located between the battery device and the apparatus in the state where the external terminal of the battery device is fitted to the connection terminal, and the lever is configured such that when the lever rotates about the fulcrum by a force applied to the gripper, the first action part applies a force to the battery device in a direction in which the battery device moves away from the apparatus. ### Claim 7 (depends on 1) The battery mounting unit according to claim 1, wherein the arm includes a connection portion between the first action part and the gripper when seen in
