Abstract
Abstract An ultraminiature tape recorder of double panel type having a case comprising front and rear (or upper and lower) compartments partitioned by a dividing means wherein, in one compartment a recess is provided for a tape cartridge with a recording button on that side. In the opposite compartment, a speaker is provided arranged to emit sound in a direction away from the first compartment, and a reproducing button is provided on the side opposite the recording button, thereby eliminating erroneous operation of the recording and reproducing buttons and permitting increased speaker size for a given overall recorder size. Means are provided whereby all of the components of the recorder are actuated on pushing the recording button, whereas all of the components with the exception of the erasing head are actuated on pushing the reproducing button.
