This invention presents a film reader equipped with a reflecting type screen, which is arranged in a housing of the reader and has a number of ring strip surfaces having different inclination angles and arranged concentrically. The common center of the ring strip surfaces is deviated from the center of the screen and locates outside of the screen and the end of the screen nearest to the common center is placed near to an observing aperture in the housing. A light source for illuminating a microfilm having recorded images and an optical system for projecting the image of the illuminated film to the screen are provided. Further, the screen is formed by one synthetic resin or preferably at least two kinds of synthetic resins having different refractive indices and mutually non-soluble property. A reflecting substance may be mixed with said resins.

An object of the invention is to provide an armature of an electric motor that provides a maximum of space for winding without causing an increase of the magnetic resistance and reduction of the coil space factor. The armature of the electric motor includes a stator yoke 5 of a stator core 1 wherein a plurality of the stator cores 1 forms a substantially annular shape; and a film insulator 4 formed corresponding to a tooth 6 and a stator yoke 5 of the tooth 6, shoes 2b and 3b being provided at locations corresponding to both side ends of a front portion of a protrusion 6a of the tooth 6, the film insulator 4 being fittingly fixed to grooves 2c and 3c by its being sandwiched between a connection-side insulator 2 and an opposite-side-of-connection insulator 3, the insulators 2 and 3 having grooves 2c and 3c at roots of the shoes 2b and 3b, respectively, along both side ends 6b of the front portion of the tooth 6.

To provide a spool for a coil winding device capable of preventing poor insulation caused by a leakage of coil wires without initially inserted coil wires staying at the vicinity of slot openings. A spool for a coil winding device of this invention includes a plurality of coil winding surfaces increased stepwise in diameter from the bottom upward in a state where the spool is disposed on the coil winding device. The spool includes a front spool part and a rear spool part, which are placed at a distance from each other so that each turn of coil has a length corresponding to arbitrary lamination thickness of the stator core. The plurality of coil winding surfaces includes a coil winding surface corresponding to the outermost coil that is formed so that a portion in a radial pattern from the vicinity of a portion corresponding to a central axis of the stator core towards an opening of the slot in which each coil is loaded is extended at least to a position corresponding to a core back where the roots of the teeth outside the slot of the stator core are connected.

A recording and/or reproducing apparatus, such as a tape recorder, includes a recording and/or reproducing unit housed within a main body portion, an electro-acoustic transducing section, an actuating input unit, first and second connection cord assemblies and first and second cord take-up units. The recording and/or reproducing unit records and/or reproduces the information on or from a recording medium, such as a magnetic tape. An electro-magnetic transducer is fed with information signals reproduced by the recording and/or reproducing unit. An actuating input unit, removably mounted on the main body portion, sets or switches the recording or reproducing state of the recording and/or reproducing unit. The first connection cord assembly interconnects the actuating input unit and the recording and/or reproducing unit for exchanging information signals, and the second connection cord assembly interconnects the electro-acoustic transducing unit and the actuating input unit. The first take-up unit is provided in the main body portion for taking up the first connection cord assembly and the second take-up unit is provided in the actuating input unit for taking up the second connection cord assembly.
