An information processing apparatus such as a computer of the class for office and home use is disclosed which employs a magnetic disk cartridge as an information storage medium, together with a disk drive assembly for information transfer with the disk cartridge. The apparatus has a housing having defined therein a disk drive compartment, in which there is accommodated the disk drive assembly inclusive of its own enclosure having an entrance slot for the insertion of the disk cartridge. Upon full insertion of the disk drive assembly into the disk drive compartment, the disk drive assembly is locked into position by a locking lever which, under the influence of a cantilever spring, engages a first opening in the disk drive assembly. The disk drive assembly may later be disengaged from the disk drive compartment by inserting a tripping tool through the entrance slot and a second opening in the disk drive assembly and exerting a force against the locking levers opposite to the force of the cantilever spring to disengage the locking lever from the disk drive assembly, thus permitting ready withdrawal of the disk drive assembly from the disk drive compartment of the information processing apparatus as for maintenance purposes.

A data transfer apparatus employs a pair of magnetic transducer heads for contact with the opposite faces of a magnetic disk for data transfer. The magnetic disk is rotatably housed in a relatively rigid envelope to make up an interchangeable disk cartridge, with the envelope having a shutter openable to expose parts of the opposite faces of the magnetic disk for data transfer contact with the transducer heads. The apparatus has a cartridge cradle movable between a first position where the disk cartridge is loaded on and unloaded from the same, and a second position where the loaded disk cartridge engages wtih a disk drive mechanism to be driven thereby. The cartridge cradle is dually locked against accidental travel from the first to the second position, in order to prevent the collision of the pair of transducer heads with each other. As the second locking mechanism, in addition to the first which is normally employed for latching the cartridge cradle in the first position, a lever for opening the shutter of the disk cartridge is adapted to positively lock the cradle in the first position even if the first locking mechanism is tripped accidentally.

A flexible magnetic disk drive to be mounted between, and fastened to, a pair of opposed holder plates forming parts of the housing of a data processing instrument such as a computer or word processor. The disk drive has a base structure comprising a platform, on which there are mounted such standard components as a drive drive mechanism and a head transport mechanism, and a pair of side walls on the opposite sides of the platform. Usually in the form of an aluminum die casting, the base structure would suffer deformation if it were fastened directly to the holder plates, due to positional errors between their screw holes. The deformation of the base structure is avoided by coupling the base structure to the holder plates via a pair of connectors which are fastened to the opposite side walls of the base structure. Each connector has a pair of lugs each having a hole formed therethrough for receiving screws or like fastener elements passing through holes in the holder plates. Being less in rigidity than the base structure and the holder plates, the connector lugs are deformable to take up possible positional errors between the connector lug holes and the holder plate holes.

A printer comprises a transportation belt, a printer head, and a pneumatic paper sucker. The transportation belt is driven by a driving roller that drives a driven roller. The printer head includes a plurality of head units each having ink-jet surfaces. In the printer, print paper is adsorbed to the transportation belt by the sucker, and transported in a direction of transportation. Ink drops jetted out from the head units are shot at correct points on the print paper specified in print data. Thus, printing is achieved. According to the printer, the printer head need not be shifted in the process of printing, but printing can be achieved at a high speed. Moreover, the costs of manufacturing can be reduced, and the printer can be designed compactly.

An exposure apparatus is arranged to project one unit of a circuit pattern onto the surface of a resist on a substrate to be manufactured and to expose it over the surface of this resist. The exposure apparatus includes a processing unit that enables forming a high-resolution circuit pattern image on the substrate by the use of an image display which is able to ensure a wide display region without deteriorating the resolution, and that when dividing the one unit of circuit pattern into a plurality of regions in order to ensure an inexpensive, reliable exposure operation, divides it so that adjacent ones of the divided regions may partly overlap each other. An exposure device includes a plurality of optical systems each of that projects one of a plurality of the divided regions onto the surface of the resist on the substrate. A control unit causes a plurality of the divided regions to be simultaneously projected on the surface of the resist in such a way as to cause duplex regions between the adjacent regions to overlap each other on the surface of the resist on the substrate to thereby cause the one unit of circuit pattern image to be formed on the surface of the resist on the substrate.

An apparatus comprises a lever provided in a housing. The lever has a stop piece on its first end which is located near a card insertion slot. The lever also has contact rollers on its second end which is opposite to the first end. The lever is rotatable around an axis with respect to a card passageway. The axis extends perpendicular to the passageway between the first and second ends. The lever is urged by a tension spring so that the contact rollers can contact a card being transferred in the passageway and that the stop piece cannot block the passageway. If a card is inserted from the insertion slot into the housing and transferred along the passageway, the card abuts the contact rollers to rotate the lever. As a result, the stop piece blocks the passageway to prevent successive insertion of two cards.

A hybrid card comprises a substrate carrying an IC chip. An IC terminal is electrically connected to the IC chip and is arranged on a first surface of the substrate. A contact region is defined around the IC terminal and is occupied when a contact terminal of a recording/reproducing apparatus electrically contacts the IC terminal. An optical recording region has a plurality of tracks extending parallel to each other on the first surface. The contact region and the optical recording region are spaced apart in a direction parallel to the tracks.

A shutter mechanism for use in a recording and/or reproducing apparatus having a guide slot through which a record card is inserted/discharged. The mechanism includes a shutter blade arranged behind the guide slot, shafts secured to side walls of the blade, and contact members, with inclined surfaces, disposed on the rear surface of the blade. The shafts are inserted into U-shaped recesses formed in supporting members so as to move rotatably and up and down. A first coiled spring biases the blade to rotate to close the guide slot, and second and third coiled springs press the blade downward to close the guide slot. During insertion of the card, the blade is pushed by the front edge of the card to rotate the blade about the shafts against the force of the first spring to open the guide slot. After full insertion of the card, the blade is returned to an upright position to close the guide slot. During discharge of the card, the rear edge of the card is urged against the inclined surfaces of the contact members to generate a force for moving the blade upward against the force of the second and third springs. After discharge of the card, the blade is moved downward by the force of the second and third springs. The contact members are secured to the rear surface of the blade rotatably in an opposite direction in which the blade is rotated by the card during insertion.
