摘要： An arrangement is designed to achieve satisfactory tape contact by setting a specific ratio for the width of a drum window and the head length of a double azimuth head. The head length L is defined as the distance from the front end of the preceding head to the back end of the succeeding head. When the drum window width W is defined as the distance of the drum window in the rotary direction, the preceding head and the succeeding head are arranged within the drum window to satisfy the relation 1.15 L.ltoreq.W.ltoreq.1.28 L. When the space S1 is defined as the distance from the front end of the preceding head to the front end of the drum window, and the space S2 is defined as the distance from the back end of the succeeding head to the back end of the drum window, the preceding head and the succeeding head are arranged within the drum window to satisfy the relation 0.075 L.ltoreq.S1.ltoreq.0.14 L and 0.075 L.ltoreq.S2.ltoreq.0.14 L. According to this arrangement, the magnetic tape intrudes preferably into the space between the double azimuth head and the drum window. The magnetic tape envelopes and contacts the head surface, so that the tendency for a spacing to occur between the head and the tape is suppressed. The reproducing output is increased and stabilized in this way.

摘要： An image forming apparatus includes a light source provided with converting structure for converting an advancing direction of light emitted from the light source, whereby a direction in which the light source is disposed can be determined regardless of a direction in which light is emitted. The advancing direction of the light emitted from a light emitting element is converted into a direction in which light transmitting structure can transmit the light, so that a luminous intensity on a photosensitive drum can be increased. The light source is designed so as to increase a light emitting area of the light emitting element and condense light emitted therefrom. The light emitting element utilizes a flat luminous unit, which is combined with a light transmitting structure in one optical piece.

摘要： A highly reliable optical disk apparatus adapted to record and reproduce the information in and from plural types of optical disks is disclosed. An acquisition unit acquires a predetermined signal from the reflected light obtained by radiating a predetermined laser on each of the optical disks. A comparator compares the waveform of the signal acquired by the acquisition unit with the comparative waveform of the signal stored in a memory beforehand and obtained from the radiated laser corresponding to the optical disk. An identification unit identifies the type of the optical disk based on the result of comparison by the comparator.
