A photographic lens system for forming an object image is placed in the lens barrel of an electronic camera. In a camera body, a beam splitter for forming branched optical paths and an image sensing element for photoelectrically converting the formed object image are arranged. An optical filter attached to a filter cap is inserted between the beam splitter and the image sensing element. The filter cap intimately contacts with the perimeter of the exit surface of the beam splitter and the perimeter of the image sensing surface of the image sensing element, thereby forming closed spaces, between the optical filter and the beam splitter and between the optical filter and the image sensing element, which allow incident light to pass through.

In a camera body section of a camera according to the present invention, a cartridge chamber unit and a spool chamber unit are located on a lower connecting member with a lens barrel unit as a central unit. Furthermore, a driving-force transfer mechanism is located under the lower connecting member. An output of a driving motor located inside the spool chamber is transferred to the lens barrel unit, cartridge chamber unit, and spool chamber unit through a driving-force transfer mechanism by changing the unit receiving the output. In particular, the driven sections of the lens barrel unit and cartridge chamber unit are driven through a worm gear. According to this camera, it requires a minimum change of each unit section to accommodate a specification change and/or a model change. In addition, it is easy to perform partial assembly of every unit.

摘要:
A cooling structure of a rotary electric machine (10) that includes a rotating shaft (16), a rotor (18), and a stator (20) that includes a coil end (22), includes a coolant passage (38) that is included in the rotating shaft (16) and through which coolant flows, and a squirt hole (42) that is included in the coolant passage (38). The squirt hole (42) is included in the coolant passage (38). An opening portion of the squirt hole (42) is positioned on an outer peripheral surface of the rotating shaft (16) and to an outside of the coil end (22) in the axial direction. The squirt hole (42) squirts the coolant such that the coolant is distributed to an inner peripheral surface (C1, C2) of the coil end (22) and an end surface (A1, A2) of the coil end (22) in the axial direction.
